A Dolls House by Henrik Ibsen Essay Example for Free

A Dolls House by Henrik Ibsen Essay Happiness is a state of well-being characterized by emotions ranging from contentment to intense joy. In â€Å"A doll’s house† by Henrick Ibsen, the feelings concerning the home are not mutual. Torvald thinks that they have the ideal home and a perfect, happy life; Nora realizes that their life is far from perfect. Their home is like a playground, it is only all fun and games—there is no real love or care. A home that is like a playground, and not filled with love and care, is not a happy home. From the very beginning, Torvald treated Nora like a baby. Is that my little lark twittering out there? † (5). â€Å"Is it my little squirrel bustling about? † (6). Before all things that Torvald called Nora, he would put the adjective â€Å"little† before it, meaning it in a patronizing manner. He looked down on Nora from the start, but that’s how she thought it was supposed to be. He treated her like a little kid, and did not love her and care for her like she needed to be loved and cared for. Nora says to Mrs. Christine Linde that she was living a happy life. â€Å"The last eight years have been a happy time for me, I can tell you. (82). Nora believed that she was supposed to be treated like a little girl, just as Torvald treated her. She was not aware that she deserved to be treated like an adult and not a little kid. She deserved to be treated with kindness, respect, love, and care. At this point of the story, she has not yet realized how a husband is truly supposed to act. Nora compares their house during the past eight years she has spent with Torvald to a playroom; they had been like little kids just playing around, not a married couple. Our home has been nothing but a playroom†¦That is what our marriage has been, Torvald. † (288/289). Nora now realizes that they have not been living a truly happy life. Their marriage has been just like little kids playing ‘house’; they had been playing a ‘game’ and not truly acting like a married couple should. Nora decided that she wanted a husband who would love her and care for her, not one that just treated her like a little doll. â€Å"It was then it dawned upon me that for eight years I had been living here with a strange man. (302/303). This is when Nora realized that she wanted something better in her life and that Torvald was not right for her. She realized that Torvald was only a stranger, not really her husband. Spouses are supposed to love you with everything they have, care for you and adore you. All Torvald cared about was money; he thought money could buy happiness. Nora knew this was not true and she could not take it anymore, so she stopped considering him her spouse. Nora and Torvald think they have the ideal life, until Nora comes to the realization that Torvald’s life revolves around money and material objects. She realized that Torvald didn’t show her the love and care that he should have. So in order to be happy, she needed to be free from Torvald, so she divorced him. Divorcing him gave her the capability to go find somebody else to marry, and have a home with true love and true happiness. The key to having a happy home is having a home filled with love and care.

Adolescents Influence In Family Decision Making Social Work Essay

Adolescents Influence In Family Decision Making Social Work Essay Abstract This study examines the perceptions and behaviour of Adolescents influence in family decision making in different family circumstances and what products are more influenced through the child more than the adults. The research findings are based on different journal articles that show how much power children have in the decision making process based on different members of the family perceptions and how they get their message across on what they want through coalitions or solely on their own. In terms of family types; single-parent and step-families are increasing in todays society compared to intact families. Its now not unusual for parents to divorce and move on with someone else. This will make an impact on the childs role in family purchase decision making. Being a child in a single-parent family suggests that they have more power in the household whereas being a member of an intact family can cause disruption as there are many people to please in that household. However, in many circumstances the parents perceptions do not always agree with the childs opinion. A number of explanations and examples for this are given. Introduction For a long time, Adolescents have played an important role throughout family purchase decisions, with their capability to have an impact to directly and indirectly influence the decisions families make when purchasing products. (Thomson, Laing, McKee, 2007). This is put into practice throughout all different types of families, whether it is an intact family of 4, a family triad, a single parent family of 1 or a mix matched family making it a step-family. This means the perceptions on adolescent influence in decision making depend on what family the child belongs to. Adolescent behaviour is also important when the child makes an input into the decisions of purchase making. Coalition being the behaviour type authors focused on as children recognized a frequent need for a purchase between more than one family member and in the end created a coalition (Thomson, Laing, McKee, 2007). These include different members of the family working together with the child in order to make a stronger influence on family decisions whether it is a parent or a sibling. Children therefore play a part in family decision making no matter how big or small and the products in question can vary from groceries to holidays. Junk foods, toys, kids clothes and accessories for school are a few of the main products that children have been known to have a strong influence on. (Mangleburg T. F., 1990). Research on how much influence children have on certain products will also be explored. Childrens Behaviour -When and how do they influence buying? Children constitute a huge secondary market by influencing family purchases (McNeal, 2008). As soon as children have established the concept of using communication skills to make demands, they are then more involved in making an influence in family decision making. (Furnham, 1998), showing that from the moment they can talk, they will automatically have an influence on buying highlighting the fact that children are becoming a significant part to the family decision making process on purchases at an early age. The most important behaviour for a child when they influence decision making is the use of knowledge and information. When contemplating child purchase power, research shows that this is known as a uniting topic (Thomson, Laing, McKee, 2007). To get a child to participate in the decision stage of buying, knowledge is a great source as it points out the cleverness or experiences that the children have when a purchase is carried out by a family (Thomson, Laing, McKee, 2007). Inf ormation is also important as it shows whether the child knows about the products in question or not. Knowledge and Information is a significant role in justifying the childs choice of products and is the main factor on how they influence on the buying stage. Parents can decide whether the childs reasons are enough to buy the product in question through their knowledge and information. Studies show that lots of parents encourage the use of knowledge and information and are foreseen characteristic of some family decision making (Thomson, Laing, McKee, 2007). How do coalitions affect adolescents decision on purchasing? Coalition behaviour involves at least two members of a family to get together to form an alliance to influence the end decision of a purchase within a family. This process is often termed majority rule (Pearson, 1989). Majority rule may have a bigger impact than just the childs influence; therefore a child may form a coalition with another family member to make their influence have more of an impact on the final decision of the purchase. However, there have been authors that convey this as lousy behaviour. (Sheth, 1974) and (Belch et al. 1980) felt that coalition would be few and far in between. Coalitions can come in different forms: Mother and child, Father and child or if there is more than one child, siblings could get together. This can benefit the child as one parent might be easily persuaded into giving the child what they want and more understanding of the childs needs. It was distinguished that a significant number of coalitions occurred between mothers and daughters than mo thers and sons concluding that when the same-sex members of a family unite to influence a decision on a product that they have more power than what different-sex members would (Beatty Talpade 1994). This would suggest that daughters had more chance of having a stronger influence in the family household compared to sons when they both wanted to convince their mother of purchasing a product. Family Triads Should the child have an input? Before buying products for any family, there is a decision making process that they must think about in order to come to a concluding decision on what to purchase if they have children. This involves three stages of decision making; gathering information, negotiating within the family and the overall decision on what to buy. Family triads are found to disagree in their perceptions of adolescent influence on both a wide selection of products and general influence in family decision processes. Mothers, fathers and children all, however agree that children have some influence in purchase decisions for a variety of products. Previous research has put forward the fact that two family members can disagree in evaluating purchase decision influence (Burns Hopper 1985). Each member of the family triad had different opinions on how much power the child actually has when deciding on purchasing a product in studies shown in the Journal of Consumer Research. Out of 161 families from North Wester n Towns, The children themselves agreed that they have influence when shopping with parents, suggesting stores, brands and products, paying attention to new products and learning the best buy. Mothers and Fathers also agreed to some extent that the child had general influence on these factors when buying products. However, suggesting the price was one of the factors that all three members of the family agreed that the child does not have influence on the price of products (Foxman, Tansuhaj, Ekstrom, 1989). This concludes that not only does the children themselves think they have influence throughout the decision making process on products but the other members of the family also agree that children should have their say. Overall, family members regarding adolescent purchase decision influence came to the conclusion that: Families that agreed on the same level of childrens influence had older fathers, a concept-oriented family communication style, less children, and a mother who was a housewife. This would suggest that a family triad let their child have more influence than a family with more children would. Other family types does the child have more power in a single-parent family? There are different types of families where a child can influence on family decision making when buying products. Family triads are one but there are also single-parent and step families. Intact families can also have more than one child meaning there are more children to have an influence on the decision making. There has been a growth in rapid social change over the years where parents are divorcing, children are living with only one of their parents or living with people that are from another family due to one of the parents falling in love with someone else. The more a family has differences, the more likely they will have to face difficulties when making important decisions as consumers (cf. Rindfleisch, Burroughs, and Denton 1997). Children gain their knowledge and information through events such as going to school, eating out and technology. However, their family members are one of the most important sources a child could possibly have through their period of consumer learning (Moschis and Churchill 1978; Moschis and Moore 1979; Ward 174). This contributes to the fact that children grow up surrounded by their family; therefore they learn from their mothers, fathers or an older sibling. Depending on what family type the child belongs to, there will be a different level of how much influence they have. Studies (Darley and Lim 1986) show that children in single-parent families had greater influence in a family outing decision than did children in dual-parent families, but did not ascertain between intact and step-families. If a child has to convince two parents, it may be difficult as they will both have different opinions on products or will have the same opinion which will overrule the child, therefore a childs influence in a single-parent household will be much stronger as there are less people to convince and the bond between the child and parent will be stronger as they have went through certain circumstances to end up on their own. Two parents can joi n forces to back up each other when they dont agree with the childs influence when purchasing a product (Mangleburg, Grewal, Bristol, 1999). This will make the childrens influence weaker compared to the single-parent household which appears to be much stronger. A single-parent household is seen as the family type to let the child have a stronger influence on decision making when purchasing products as the child only has one parent to do their parental duties which means the parent will have weaknesses in parental control and find it difficult to be the boss all the time meaning the child will have more independence and equal rights to influence to balance out the family (Dornbusch et al. 1985; Hetherington 1988; Thomson, McLanahan, and Curtin 1992). Family type does have an impact on adolescents influence on decision making and specifically, children in single-parent families had greater influence in both types of decisions as compared with children in step families and intact fami lies (Mangleburg, Grewal, Bristol, 1999). Products children have more influence on Junk foods, toys, kids clothes and accessories for school are a few of the main products that children have been known to have a strong influence on (Mangleburg T. F., 1990). This information suggests that children have more power over products and services that they will be experiencing themselves as children tend to have more of an influence in product sections that are most significant to the children themselves (Beatty and Talpade, 1994). Contrasting, children dont have much of an influence on decision making for products that are expensive and not used only by the child (Foxman et al.,1989a, 1989b). Expensive items such as cars, TVs and furniture are not influenced as much by children as these as more expensive buys. The adults of the household feel they have more influence on bigger products that will affect the whole of the family. Studies from the Journal of Consumer Research (Foxman, Tansuhaj, Ekstrom, 1989) back this up as out of 161 families from North Western Towns, Both the parents and children feel that the parents should have more say overall on products such as Home computers, cars, furniture and cable TV. It appears that children do have a strong influence when it comes to decision making in the family based on purchasing products. However, the childs influence on certain products is weaker than the parents due to the price and who uses the product. Although some research has found next to nothing child influence for bigger, family buys, others have found higher levels of influence than was foreseen by earlier research ( Foxman Tansuhaj 1988; Lee and Beatty 2002). Family holidays and events that see the family come together to have fun are other purchase decisions that children can play a part in influencing (Mangleburg T. F., 1990). These products are seen as expensive and a treat for all the family, this shows that some authors may find that children dont have much influence on expensive products whereas others will find children do have in fluence on products more expensive than clothes and food. Grocery shopping within different families It has been proven that children have more influence on food shopping than expensive buys in the last section of this review. It has also been proven that children have different levels of influence in different family types whether it is a single-parent or dual-parent family. Studies show even though children have a strong influence on purchasing food, the level of influence differs depending on what family the child belongs to. Children in single-parent families are more likely to take part in family tasks, such as going shopping than other children do in bigger families with their parents relationship still intact. (Weiss 1979; Taylor, Glynn, and Taylor 1985; Peters 1985). This would suggest that the child in the single-parent family will participate more in influencing what is bought for the grocery shop compared to the dual-parent family where there are more people to influence what is bought. Summary and conclusion Adolescents influence the decision making process in the family when purchasing products. However, there are different levels of influence and this depends on what family type the child belongs to as this has an effect on how the parents relationship with the child helps or hinders on how much influence the child has when the decision making process is being done when buying new products differing from groceries, clothes and holidays. The review helped come to the conclusion that the most important behaviour for a child when they influence decision making is the use of knowledge and information. Knowledge and Information is a significant role in justifying the childs choice of products and is the main factor on how they influence on the buying stage. It has been discovered that a childs influence solely on their own against both parents can sometimes be overruled by the parents. This is when the child forms a coalition to get more support to gain a stronger influence on the decision making process It was distinguished that a significant number of coalitions occurred between mothers and daughters than mothers and sons concluding that when the same-sex members of a family unite to influence a decision on a product that they have more power than what different-sex members would (Beatty Talpade 1994). This review suggested that different family types determined the level of influence the child had, this included single-parent families, triad families and step families. However, mothers, fathers and children all agreed that children play a part in influencing a number of products in purchase decisions (Foxman, Tansuhaj, Ekstrom, 1989). Products that children have more influence on were also researched. Findings suggest that products that are actually used by the child themselves and not expensive were found to be the products children had more influence on whereas children have been found to have less influence on decisions making for products that are more expens ive and are not just used by the child themselves (Foxman et al.,1989a, 1989b). Grocery shopping is another group of products that children have influence on and the level of influence depends on what family type they belong to. It was found that children belonging to the single-parent family have more influence than children in a dual-parent family. Overall there are different levels of influence a child has when the family are making decisions and it all depends on family types, children behaviour and the products in question.

Cracks Detection using Digital Image Processing

Cracks Detection using Digital Image Processing Cracks detection using digital image processing   in MATLAB Usually visual investigation methods have been used for inspection and monitoring of concrete infrastructures. Huge and tall structure such as cables bridges, high rising towers, dams and industrial power plant are known to have an inaccessible area and limitations in inspection field due to its geometry structure which is often dangerous , labor -intensive and involves lot of risks. So, with rapid development in technology and its uses, researcher   are trying to overcome these problem. Every now and then some research is going regarding these problem and trying to overcome it. So, I also have come with the idea of using digital Image processing   in mat lab to detect the cracks in such structure. Literature   Review:- As   of todays world, digital Image processing is getting better and better   and used in all areas of science. With   the help of digital image processing tools, various image processing can be applied to detects the cracks in structure. Not only in structures but also for   bridges, towers, power plant and also in structure   like steel ,roads, fatigues and sewer pipes. A number of research studies have been conducted regarding   detection of cracks by using Digital   image processing .(1)The author of Korea Institute   combines UAV technology in the process of recent breakthroughs and digital image analysis techniques   to detect cracks in structure. In this study, the crack detection program with digital image analysis techniques was developed in order to the crack and width of the structure automatically. The developed program attempted to perform the image analysis for crack detection with Morphology method based morphological hydraulics and specially designed Morphological link for crack(Morph link-C)algorithm for S/W development was applied to the program. The digital image was acquired in order to evaluate UAV applicability and performance and field application of the crack detecting program after targeting the bridges in common use. Comparing with the measured values in order to verify reliability of the new structural inspecting system for application in this study, it is verified that the accuracy above a certain level is secured. Also, The below three core technologies shall be considered to develop the technology possible to detect cracks and calculate crack width of large structure through the digital image analysis and to put this technology to practical use. Optimal digital image acquisition and filming equipment configuration Crack analysis technique of a number of mass digital images Combining technique of multiple images that different positions are captured And also the author from china(2)  Ãƒâ€šÃ‚   proposed   inspection system for measuring cracks in concrete structure and providing objective crack data to be used in safety assessment. The system consists of the mobile robot system and crack detecting system. The mobile robot system is controlled to keep a constant distance from the wall to acquire image data with a CCD camera on scanning along the wall. The crack detecting system extracts crack information from the acquired image using image processing. To improve accuracy of crack recognition, the geometric properties and patterns of cracks in a structure were applied to image processing. Also,   an inspection system using an image process, which can be a solution to the problems of crack detection in concrete structure, slow rate, subjectivity, and the inefficiency in managing data. Also, the system ensures the validity and possibility based on the experiment in the indoor structure, road tunnel, and subway tunnel. However, an erroneous recognition of a crack as non-crack and vice versa prevails. Therefore, the system is semi automated to get rid of wrong recognition of non crack as crack, and to identify crack by a graph search method using the user-based input of the start point and end-point of crack. In order for a crack inspection system to develop into an expert system, there needs to be further study of the characteristics of cracks and the algorithm must move towards complete automation. Similarly,(3) The Komatsu Engineering Company has developed and commercialized an image acquisition system that can acquire the images of road and tunnel lining by using a laser-scanning device .(4) The Railway Technical Research Institute in Japan developed an image acquisition system of railway tunnel lining by using line CCD cameras. (5)Road ware Group Inc., Canada commercialized a system that acquires an image of the road with a CCD camera, an ultrasonic sensor, and a gyro-sensor with a speed of80km/h and a resolution of 3~4cm [7]. Those systems are useful to collect data of cracks, leakage, scale, and spall but only by using the image acquisition, and not through automatic defect detection. The algorithm for crack detection and measurement is required for fully automatic inspection system. It is necessary, therefore, to develop the automatic crack detection and measurement algorithm to obtain both fast inspection and objective crack data. From the author of University of central Florida , paper describes the mechanism of non-destructive bridge inspection methods using HRDI and HDV digital crack detection and IR thermograph   technology and the benefits of the combination thereof. The feasibility of applying these technologies for in-service bridge inspections are demonstrated and evaluated in the State of Florida under  the university-government-industry collaboration research program. The purpose of the joint research effort is to utilize the innovative technology for more efficient bridge inspection programs and bridge management in Florida by developing a new quantitative performance measure for long term bridge monitoring, such as crack ratio and delaminated area, and the use of objective data resulting in more efficient and scientific bridge inspection database and management system. With the quantity of roadway structure assets increasing annually, coupled with concurrent increasing rates of deteriorati on being experienced by many of the existing structures, bridge owners need to find new and creative ways to ensure the structural safety of their bridges while they all too often face problems of reduced budgets and dedicated bridge inspection resources. Currently, the determination of bridge condition ratings in  many countries is generally subjective depending on individual inspectors knowledge and experience, as well as varying field conditions. For the evaluation and documentation of concrete deterioration (cracks, efflorescence, delaminating, spalls, etc.) and changes overtime, the current practice of visual inspections can be lacking in accuracy and completeness, as well as time consuming and costly if road closures and access equipment  are required for the inspection. Using the proposed new non-destructive technologies, bridge engineers can quickly and efficiently obtain objective current bridge condition information that has traditionally been obtained by more time con suming and more subjective close-up visual inspections and sounding tests. The digital output of these NDE inspection techniques improves on-site inspection safety and objectivity and contributes to improved inspector efficiency by significantly reducing the amount of inspection time in the field. However, it must be noted that while most of the NDE or sensor technologies do offer new efficiencies and/or additional objective assessment results to the bridge inspection process, they are not a substitute for inspectors conducting on-site specific follow-up and detailed structure investigations. While improved efficiencies in bridge inspection methods resulting from the application of the above NDE technologies bring significant benefits to the overall bridge inspection process, they are not a substitute for the continued need for sound and experienced engineering judgment. The authors believe that by offering new and improved inspection technologies to experienced bridge engineers and inspectors, bridge inspection programs will be strengthened through enhanced inspection data and will be more objective, consistent, scientific, and efficient. Based on the nature of calculation   and development of technology approach to process image, Image Processing Technique for crack detection can be divided into several categories. Each image consists of pixel which are represented by its integer values from 0 to 255. Based on these pixel values Operation technique conducted is accomplished in the spatial domain. However , desirable outcome cannot be obtained in spatial domain. So in this case ,usually Fourier or wavelet transformation is performed on the image. Again, the outcome image is processed in frequency domain. After wise, to reconstruct the image in spatial domain   an inverse transformation is applied. Another procedure to detect cracks using image is based on the training algorithm to solve a problem. In this process ,some technique directly deal with image without any training while other first construct   a database which is divided into two subsets, the subset with crack image and subset with un-cracked images. For each subset ,a decision line is defined to represent the characteristics index, such as shape factor. With the help of these image , a program is used which is capable of comparing new images with decision line and assign it to the subset where it belongs. Especially Neural network and clustering   method are widely used among the popular training techniques to learn the decision line. Basically, two approaches have been applied to detect cracks from the images.   Using dye solution and the other is without using dye solution to the surface material. Usually ,In this dye based detection process, a particular dye solution such as fluorescent is injected on the surface of concrete or other material. Depending on the solution type   and color special or ordinary cameras are used to scan the surface of the material. These dye based method were used in past for detection of mini or micro cracks in different types of material like concrete ,ceramics tiles etc and also any kind of structure. The other approach for finding crack   is based on the color image without using dye solution. Since these method is less costly and less time consuming it is currently more popular. A number of research studies have been conducted regarding the surface   crack detection technique in different material. One of these attempts can be seen in work of Kittler at al. They proposed an idea of training based algorithm to get samples of the region, which are void of defects in the spatial domain. In this process, the new pictures were analyzed for the presence of any defects and also to find the location of the defects. In this method, clustering technique and morphological operation were performed to analyze the images. The experimental output of this method is shown in the figure below.   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   Figure . Crack detection on ceramic tiles (Kittler, Marik, et al. 1994) Image processing technique has been used for inspection of cement based materials for micro cracks and other micro defects (Ammouchea at al 2000). In this process, a red dye solution is used with the surface. So the dye solution can penetrate the porous region of the surface while the excessive solution are   removed by polishing the sample surface. Once the dye solution is injected, a color image of 256 x 265 was taken from camera of the surface. The following operation is carried out on the taken image. O(x,y) = max { R(x,y)0 G(x,y) } Where, O(x,y) à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ Intensity of the output gray level image at (x,y) co-ordinates R(x,y) à ¢Ã¢â‚¬  Ã¢â‚¬â„¢Ãƒâ€šÃ‚   Intensity of the original image at (x,y) co-ordinate in red region. G(x,y) à ¢Ã¢â‚¬  Ã¢â‚¬â„¢Ãƒâ€šÃ‚   Intensity of the original image at (x,y) co-ordinate in gray region. Afterward, using a thresholding value, the gray level   image is converted to the binary image. Then, using entropy maximization method value of the thresholding is evaluated. This method is based on maximization of the entropy function à ¡Ã‚ ´Ã¢â‚¬Å" of gray level pixel. à ¡Ã‚ ´Ã¢â‚¬Å"(k)=   [  Ãƒâ€šÃ‚   ] where, Pà ¡Ã‚ µÃ‚ ¢ is the probability of a given pixel to have an intensity of i (Pà ¡Ã‚ µÃ‚ ¢=Nà ¡Ã‚ µÃ‚ ¢/N)   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   Ni Number of pixel having i intensity   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   N Total no of pixel   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   Wà ¢Ã¢â‚¬Å¡Ã¢â‚¬â„¢ W1 Lower and upper bound of the probability to find pixel intensity And also computed as:-   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   k Based on the threshold to obtain binary image, a lower bound thresholding operation is performed. Then , using two morphological operations of eroding and rebuilding the binary image is post processed. This operation is conducted to eliminate noisy and small objects (i.e. Less than 10 pixel) from the image. However, second series of operation are needed to obtain the shape factors which are used to decide whether the pixels in a binary image are associated with cracks or other defects. To do so, a dimensionless packing density index Fc is defined. Fc = (2-4) Where, Aab=Object area Aac= Area of its circumscribed circle The value of Fc is equal to 1 for a circle and tends towards 0 for a very elongated object.Fig below shows results obtained in this method Fig. Also, Abdel-Ghader (_Abdel,Osama and kelly 2003) proposed an idea to find cracks on concrete surface using image processing technique .In this work, they implemented   and compared 4 cracks detection method   which include Fast   Haar Transform( FHT), Fast Fourier Transform( FFT),Sobel edge detector   and canny edge detection. They used 50   concrete image from a bridge deck of which 25 pictures with cracks and 25 pictures without cracks for   their research .From their research ,they concluded that FHT was more efficient and effective method rather than other 3 method. Basically, FHT, a simplified   Wavelet transformation decomposes the image into low and high frequency components, the mother Wavelet à ¡Ã‚ ´Ã‚ ª(t) of Haar function and scaling à ¡Ã‚ ´Ã¢â‚¬Å"(t) are defined as: à ¡Ã‚ ´Ã‚ ª(t) =   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   Relationship between Haar wavelet and scaling function and scaling function with itself is shown below   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   à ¡Ã‚ ´Ã‚ ª(t)=)   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   (t)=) In this process, to detect crack the three quadrants of the first level transformation i.e. 2,34 are passed through a high pass filter to reduce nose and   combined together to get magnitude of images. To decide whether crack exists or not, an empirical thresholding value is used. Fast   Fourier transfer motion (FFT) are used to derive the frequency component of the image intensity. The transformation and   the inverse transformation were carried out using: F(u, v)= F(x, y)= The canny edge detection is a convolution filter to detect filter noise from the image while processing. In addition, thresholding value is defined to see if a pixel belongs to an edge region or not. The   Sobel edge detection is also a convolution filter defined for vertical and horizontal edges in images. This edge detection technique helps to detect the change in the image intensity in neighboring pixels. Filtering was done using convolution operation for each filter separated. Then, two filtered images is combined together at each location and result is a gray level image with enhanced edges. G x =   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   G y= Default value of thresholding is defined as  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   where Another attempt to detect cracks in concrete specimen using optical fluorescent microscopy can be found in   this research( Litorowicz   2006). To continue these processes, a fluorescent dye solution   was used. The specimens were then light using Nikon optical microscope at a magnification of 10 times. The images were captured using a Sony DXC 350 P video camera. Then, image pro Plus analysis software was introduced to perform the image processing operation. Then, using segmentation method, the RGB images is connected into a binary image. The threshold level was calculated based on the effect of the dye solution to the surface. To distinguish cracks pattern, several parameters were introduced: Angle between the vertical axis and the major axis of the ellipse covering   the connected component Area of each connected component Dendritic   length, which is the total length of all the one-pixel thick branches.   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   4.

This research was conducted to develop an automatic detection system that analyze the concrete surface and visualize the crack more effectively and efficiently. Basically this research consists of two parts: Image processing and image classification. First stage include image processing tools like filtering, subtraction and morphological operation in order to extract cracks from the background image (i.e. data such as the number of pixel and the ratio of major axis to minor axis for pixel area. While in second step, existences of cracks are identified using neural network to automate the image classification. In this process, 105 images (cracked and non-cracked) of concrete were used as a trained image including every kind of cracks. Following steps were carried out for image processing : Fig. Image processing steps   to detect cracks First step in image processing is to convert RGB image into gray level intensity image followed by a subtraction transformation as follows: à °Ã‚ Ã‚ Ã‚ ¼Ãƒ °Ã‚ Ã¢â‚¬ËœÃ‚  (à °Ã‚ Ã¢â‚¬ËœÃ‚ ¥Ãƒ °Ã‚ Ã¢â‚¬Ëœ- ) = à °Ã‚ Ã¢â‚¬ËœÃ… ¡Ãƒ °Ã‚ Ã¢â‚¬ËœÃ… ½Ãƒ °Ã‚ Ã¢â‚¬ËœÃ‚ ¥ {à °Ã‚ Ã¢â‚¬ËœÃ… ¡Ãƒ °Ã‚ Ã¢â‚¬ËœÃ¢â‚¬â„¢Ãƒ °Ã‚ Ã¢â‚¬ËœÃ¢â‚¬ËœÃƒ °Ã‚ Ã¢â‚¬Ëœ-à °Ã‚ Ã¢â‚¬ËœÃ… ½Ãƒ °Ã‚ Ã¢â‚¬ËœÃ¢â‚¬ ºÃƒ °Ã‚ Ã¢â‚¬ËœÃ‚ ¥Ãƒ °Ã‚ Ã¢â‚¬Ëœ-à °Ã‚ Ã…“-à °Ã‚ Ã¢â‚¬ËœÃ¢â‚¬ ¦Ãƒ °Ã‚ Ã¢â‚¬Ëœ- [à °Ã‚ Ã‚ Ã‚ ¼(à °Ã‚ Ã¢â‚¬ËœÃ‚ ¥Ãƒ °Ã‚ Ã¢â‚¬Ëœ- ) à ¢Ã‹â€ Ã¢â‚¬â„¢ à °Ã‚ Ã‚ Ã‚ ¼(à °Ã‚ Ã¢â‚¬ËœÃ‚ ¥Ãƒ °Ã‚ Ã¢â‚¬Ëœ- )], 0} Where ,I(xi)   and I(xj) are   the intensity pixel of xi and X j respectively.   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   Ri Neighborhood of that pixel xà ¡Ã‚ µÃ‚ ¢ . When the subtraction is negative number, it is represented as zero. Once improved subtraction method is used, threshold value is defined to detect cracks more effectively. The thresholding operation is given as: à °Ã‚ Ã‚ Ã‚ ¼Ãƒ °Ã‚ Ã‚ Ã‚ ¼Ãƒ °Ã‚ Ã¢â‚¬ËœÃ‚  (à °Ã‚ Ã¢â‚¬ËœÃ‚ ¥, à °Ã‚ Ã¢â‚¬ËœÃ‚ ¦) = {2 ÃÆ'- à °Ã‚ Ã‚ Ã‚ ¼Ãƒ °Ã‚ Ã¢â‚¬ËœÃ‚  (à °Ã‚ Ã¢â‚¬ËœÃ‚ ¥, à °Ã‚ Ã¢â‚¬ËœÃ‚ ¦) à °Ã‚ Ã¢â‚¬Ëœ-à °Ã‚ Ã¢â‚¬ËœÃ¢â‚¬Å" à °Ã‚ Ã‚ Ã‚ ¼Ãƒ °Ã‚ Ã¢â‚¬ËœÃ‚   > à °Ã‚ Ã¢â‚¬ËœÃ¢â‚¬ ¡   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   à °Ã‚ Ã‚ Ã‚ ¼Ãƒ °Ã‚ Ã¢â‚¬ËœÃ‚  (à °Ã‚ Ã¢â‚¬ËœÃ‚ ¥, à °Ã‚ Ã¢â‚¬ËœÃ‚ ¦)  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   à °Ã‚ Ã¢â‚¬Ëœ-à °Ã‚ Ã¢â‚¬ËœÃ¢â‚¬Å" à °Ã‚ Ã‚ Ã‚ ¼Ãƒ °Ã‚ Ã¢â‚¬ËœÃ‚   à ¢Ã¢â‚¬ °Ã‚ ¤ à °Ã‚ Ã¢â‚¬ËœÃ¢â‚¬ ¡ To further smooth the image, a Gaussian law pass filter was applied. Then, an input gray level image is converted to a binary image where the values are represented as 0 or 1. Using Otsus   method or valley emphasis method, the threshold value was selected. Morphological image processing including closing and   labeling were applied to the image to extract image component such as shape of crack. The optimal parameters and their level associated with above operation are   mentioned below:   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   Fig. Parameters and their levels Using Artificial Neural Network (ANN) crack images were distinguished from non-cracked images. Also images were automatically identified as the crack or non-cracked images using ANN. The output value was represented either cracked (value 1) or non-cracked (value 2). Another example of tracing based image processing technique can be found on Nishikawa research paper (2012). A robust automated image processing method was applied to crack detection on concrete surface. This method consists of two parts: First part consists of automatic construction of a filter for crack detection while the other part consists of noise removal and determination of indistinct cracks using iterative process. Using generic algorithm the part is conducted, where genetic individuals was represented as a tree structure. Using a trained   program, a large number of images were combined and several images filtered were converted into a tree structure. An illustration of tree structure concept is shown below.   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   Fig. Construction of Tree structure   with multiple filters(Aoki and Nagao 1999) A combination of generic program was computed to train the program and results were compared to the target image (i.e. image generated by visual inspection. The comparison was between the distinct distributions of brightness between the images. To measure the filter performance the following formula was used. E= Where,    N- No of training images in database K-th target image -Output image -weighted image . -   Brightness of the weighted image in crack region )- brightness of k-th target image at position (i,j) To reduce the false negative result, a superimposition operation using low resolution image was implemented. Figure below shows the algorithm used in above algorithm. { algorithm}

Frankenstein Speech Outline :: Mary Shelley Shelly

Frankenstein Speech Outline Introduction What happens when you abandon somebody that you use to care for so dearly? Are they mad and want revenge because of this or do they keep on living their life? In the story Frankenstein by Mary Shelly, Robert Walton, the captain of a ship bound for the North Pole, recounts, to his sister back in England the progress of his dangerous mission. Successful early on, the mission is soon interrupted by seas full of impassable ice. Trapped, Walton encounters Victor Frankenstein, who has been traveling by dog-drawn sledge across the ice and is weakened by the cold. Walton takes him aboard ship, helps nurse him back to health, and hears the fantastic tale of the monster that Frankenstein created and abandon. The monster in Frankenstein goes through a lot of phases and changes and has traits such as being confused, sad, evil, good, and depressed. In the story Frankenstein, it suggests that people must take responsibility for what they do. (First, let’s talk about the very beginning of the monster’s life) Body I. Monster’s misunderstood by everybody. He doesn’t understand why people didn’t like him at first, until later on in his wandering. Making him confused and depressed all of the time because of this reason. A. People run away in fear of him, or try to kill him to get rid of him. Even his creator abandoned him. Everybody won’t give him chance to be understood, he is a mystery to everybody, representing the question marks going down the face for his confusion. 1. I, the miserable and the abandoned, am an abortion, to be spurned at, and kicked, and trampled on. (115) This line evokes the motif of abortion: the monster is an unwanted life, a creation abandoned and shunned by his creator. 2. The monster Frankenstein travels alone by himself a lot so no one hurting or screaming at him since he is the eight-foot-tall, hideously ugly creation that everybody runs in fear of. The monster clearly understands later on in the story his position in the world, the tragedy of his existence and abandonment by his creator. 2 3. The monster assists a group of poor peasants and saves a girl from drowning, but because of his outward appearance, he is rewarded only with beatings and disgust. Making him having to fight back and run away. B. Wants to be loved and taken care of, he also wanted to know his purpose in life and why was he created.

Stalking :: essays research papers fc

Based on a study done by Schwartz-Watts and Morgan at the American Academy of Psychology Law, they found that stalking was far more prevalent than anyone had imagined: 8% of American women and 2% of American men will be stalked in their lifetimes. That’s 1.4 million American stalking victims every year. The majority of stalkers have been in relationships with their victims, but significant percentages either never met their victims, or were just acquaintances - neighbors, friends or co-workers. I have broken down types of stalkers into three broad categories: Intimate partner stalkers, delusional stalkers and vengeful stalkers. Obviously, there is overlap. Intimate partner stalkers are typically known as the guy who "just can’t let go." These are most often men who refuse to believe that a relationship has really ended. Often, other people - even the victims - feel sorry for them. But they shouldn’t. Studies show that the vast majority of these stalkers are not sympathetic, lonely people who are still hopelessly in love, but were in fact emotionally abusive and controlling during the relationship. Many have criminal histories unrelated to stalking. Well over half of stalkers fall into this "former intimate partner" category. Delusional stalkers frequently have had little, if any, contact with their victims. They may have major mental illnesses like schizophrenia, manic-depression or erotomania. What they all have in common is some false belief that keeps them tied to their victims. In erotomania, the stalker’s delusional belief is that the victim loves him. This type of stalker actually believes that he is having a relationship with his victim, even though they might never have met. The woman stalking David Letterman, the stalker who killed actress Rebecca Schaeffer and the man who stalked Madonna are all examples of erotomanic stalkers. The final category of stalker is not lovelorn. He is the vengeful stalker. These stalkers become angry with their victims over some slight, real or imagined. Politicians, for example, get many of these types of stalkers who become angry over some piece of legislation or program the official sponsors. But, disgruntled ex-employees can also stalk, whether targeting their former bosses, co-workers or the entire company. Some of these angry stalkers are psychopaths, i.e. people without conscience or remorse. Some are delusional, (most often paranoid), and believe that they, in fact, are the victims. They all stalk to "get even." In general, for any type of stalker, the less of a relationship that actually existed prior to the stalking, the more mentally disturbed the stalker.

Explain How the Understanding of Peace Is Expressed Through the Sacred Texts in 2 Religious Traditions Essay

By looking into their sacred texts and teachings on peace, we can gain a valuable insight into how these religions explain peace. The teaching of peace is central to Christianity. They use the sacred text of the bible, mostly the New Testament with emphasis on the Gospels as the source for teachings on peace. The New Testament states peace as a virtue and identifies it as a key element of God. Christians use Jesus’ example to illustrate the ideal model for peace in their lives. This model allows for adherents to understand the peace of God through the gift of the Holy Spirit and peace in relationships whereby Christians are expected to work in harmony with others in order to achieve peace As well as this the teaching on war and peace â€Å"love your neighbour as yourself. †(Matthew) and the teaching on peace and justice are both exemplified by Pope John XXIII’s notion that there can only be peace if there is justice. The Christian teaching on peace revolves around the covenant relationship between the adherent and God. This peace is given by Christ and is shown in the sacred texts of the New Testament â€Å"My peace I leave with you,† and is described as â€Å"one of the fruits with the spirit. †(Galatians). Jesus tells his followers that â€Å"in me you may have peace,† (John) suggesting that the concept of spiritual peace is embodied in the teachings of Jesus Christ. The importance of peace is clear in the Beatitudes were Jesus stated â€Å"blessed are the pure in heart, for they shall see God†. Christians believe that through baptism they have been called to follow Jesus’ as their model in life. By following his example, Christians acquire peace by obeying the commands of Jesus and therefore the principle teachings of Christianity â€Å"You must love your neighbour as you love yourself. † The bible states that Christians can achieve peace through the specific teaching of Jesus to forgive those who have wronged you. â€Å"If he wrongs you†¦you must forgive him. † (Luke). Forgiveness and compassion is at the heart of the Bibles message. Further to this, Christians can achieve peace through their practice of individual and communal prayer. The Christian biblical view on peace is one that demonstrates the idea that they should work for it. Through the beatitudes, Christians are encouraged to be the peacemakers in society. â€Å"Blessed are the peacemakers for they will be called the children of God. † Further to this, Christians believe in the sanctity of life through the covenant of the 10 commandments which state â€Å"Thou shall not kill. † Peace is work of justice and the effect of charity. In the case of conflict, Christians resort to the idea of violence being a last resort and refer to the Just War theory in order to determine whether conflict is applicable. The bible teaches adherents to promote peace on an international level, aiming to work for peace, justice and reconciliation. Islam like Christianity was a religion founded on the virtue of peace. Islam is referred to in the Qur’an as â€Å"the paths of peace† and it is taught that peace must always be actively sought out by Muslims. The Qur’an sees reconciliation as a basic stance and states that Allah abhors the disturbance of peace. Muslims too believe that there can only be peace if there is justice. In Islam, peace takes a variety of forms. It is seen as a quality of personal tranquillity and fulfilment bestowed by Allah to reward submission. This surrender of mental and physical devotion begins with the concept of Dhikr, the remembrance of Allah in all aspects of Muslim life. The Qur’an states that â€Å"In remembrance of God do hearts fins satisfaction. † This concept is embodied by the 5 pillars of Islam. Through the Salat, attention is drawn to Allah, marginalising distraction in order to devote more fully to the divine. Sawm and Zakat illustrate physical sacrifices for Islam which allows the adherent to appreciate Allah’s role as of life. The Hajj focuses on morality by allowing the adherent o come closer to Allah in their individual search of inner peace. Along with this, the study of the sacred texts of Islam, the Qur’an and Hadith equips adherents with necessary theological understanding for a meaningful life of submission which in turn brings peace. This study allows Muslims to understand peace being a reward for following the teachings of Allah and his prophet Mohammad. Peace be upon you because you have persevered. † Another concept of achieving peace is through collective worship. It encourages commitment in the struggle against the greater Jihad. Like Christianity, Islam encourages adherents to strive for peace. Both typify the complex relationship between religion and peace. The standard greeting to another person in Arabic is â€Å"As-Salamu-Alaykum (Peace be with you) † (Qur’an), which encourages Muslims to â€Å"Promote peace among men. † (Sura). There are various organisations in Islam that promote peace. E. g. The Islamic Conference which promotes world peace and safeguards the interest of the Muslim world. The understanding of peace throughout both Christianity and Islam has been influenced by their sacred texts. It is ultimately through the interpretation of these texts that adherents learn the values of peace. They all demonstrate that peace is not merely the absence of conflict, but is also a complex intertwined system of teachings and that there are various avenues to achieving the ideal state of peace.

Hispanic vs. Pakistani: Gender Roles in Society Essay

When a culture has a way of doing things, it is supposed to be like that till the end of time. Little did ancestors know, with the way society evolved some customs cannot stay the same. Jobs are now created for both men and women and money has become more of a necessity to survive. Looking at two cultures in particular, Hispanics and Pakistanis, they both have diverse views on the roles of their men and women. In addition to what is permissible and frowned upon in a culture. They each allow distinctive roles to be played in society such as workforce, and or domestication. However, the cultures both had become affected by changes such as bills, taxes, keeping a home up, providing for children, and the requirements to be allowed a career. At the beginning of time these cultures first started out, nothing else was known but what they created and put in their own minds. Both Hispanic and Pakistani men made it their mindset that they must be the provider, the one waited on. Being a working Hispanic man with no formal education, minimum wage is about $7.25 an hour. With only that kind of pay many men cannot be the only provider for their family, household, or bills therefore many endure hardships. Some men wait behind buildings, or in alleys waiting for the average man seeking cheap labor just for any extra money they can receive. In Pakistan, â€Å"the minimum wage for the factory: 4600 RPK per month (equivalent to 37 US cents an hour for a 48-hour workweek) plus the required 44.23 rupees/hr overtime for more than the standard 48-hour workweek in Pakistan (equivalent to 74 US cents an hour)† (Cook). Nevertheless, some men go against how things should be and take on the role of a stay at home dad, while women financially provide for their family. There is no set role in the society people love in today, as times changes so do people to better adapt to the way of living. When the word â€Å"woman† was spoken, many thought, subservient towards men. Contrasting men, women were treated as if they had no backbone or way of doing as they chose in the Hispanic or Pakistani cultures. The role of a woman was, awake, clean thy home till spotless, bear to all children and husband needs, and make sure food was freshly made and served by the time their husband was home from work. Without an approval from their husband, any economic activities, such as employment and ownership of property were prohibited. However, with society altering so swiftly, a man making all decisions is not a worry of many women now. â€Å"The factor most responsible for the earlier high growth rate was the rapid increase in the labor force participation rate of women, which stood at 34 percent in 1950 and increased to 60 percent by 2000. The number of women in the labor force rose from 18 million in 1950 to 66 million in 2000..† (Toossi). Women found the reason to start working actual jobs to have a better chance of surviving in society and it’s vast changes. Hispanic women have the chance of a formal education, but if not financially able there are many low-class jobs that do not require a proper education. Most Hispanic women who are single mothers, or are the only person providing find quick and easy jobs like janitors, maids, servers, and retail, receiving only minimum wage or a little higher. * How much pakistani women get paid without formal education, how do they survive?
