Establishing a service composition frame work for smart healthcare system
As the idea of location awareness has already matured and numerous applications are flooded in today???s word, the logical next step reasons out, to context-awareness. Though the idea of context-awareness has been in the research field for close to two decades, the recent advancement in Internet of Things has brought a more compelling thrust in its research. Sensor networks integrating billions of sensors and actuators will be prevalent in the near future producing big data. Filtering and analysing this data with the contextual information will yield more significant results. But deducing the context information itself poses many challenges and unresolved research problems. Context-awareness systems involve acquiring, analysing, reasoning the data and composing the services for suitable action. Service composition either by orchestrating or choreographing technique has been deployed in certain applications, however, each domain requires unique methodology. Healthcare has always been the top priority when it comes to applying novel technologies. Applying context-awareness computing in the healthcare service sector is of paramount importance. The problem context for this research lies in a cardiology speciality hospital???s Intensive Therapy Unit or the post-surgery recovery ward which has lot of scenarios emanating that involves course of actions to be delivered by the healthcare professionals depending on the context. Depending on mere human service may not be adequate. With the available advancements in technologies, it would be possible to leverage optimum service in that time critical situations, provided technology can sense the changes in context and act accordingly. The course of actions to be taken involves an amalgamation of understanding the location, presence availability, relevance of and coordination among various departments, machines and personnel. This can be summarized as ???Response??? with ???Context-Awareness???. The primarily task is to sense the context and then determine and locate the relevant services, which are distributed in the World Wide Web, to achieve a goal situation as a solution to the problem. In order to deliver such a solution we need to develop an exclusive context-aware framework. The existing frameworks will not be adequate to meet such a demanding situation and hence, the research problem is to evolve a comprehensive service composition framework for smart healthcare systems. In order to solve this problem, a use-case approach was followed. After identifying an appropriate use-case, the solution was first modelled using Automata. The concept of service automata and timed automata were fused to deliver a timed-service automaton which is appropriate to model and test the framework and algorithm for service composition. As a solution to the research problem, a composition based framework of a context-aware smart healthcare system has been presented. It will guide software developers to deploy services for critical healthcare, under the umbrella of Service Oriented Architecture. The matured concept of Automata has been tweaked to present novel timed-service automata which will enable service composition precisely for meeting the time constrained demands of modern healthcare service requirements. It has been tested with UPPAAL verification tool for validity and concurrency. A prototype has been implemented to study the validity of the established framework. Apache JMeter tool was used to test the strength of the services and engine developed based on the proposed algorithm for effective service composition. -

Evaluation and analysis of quality in e commerce (B2C Website) /
There has been a phenomenal growth in Ecommerce in the last few years and it is still growing. As the market is expanding, more and more organizations want to have web presence. Due to sudden and rapid demand in Ecommerce website, website development companies are ignoring or skipping the quality factor. Apart from this, due to popularity of Internet, more and more consumers are buying products and services through ecommerce websites. The software development companies want to delivery the products quickly, to make fast money. To meet the deadlines, usually the quality of the product is not taken as a priority, resulting in a product full of bugs, being shipped to the customers. Once the software becomes live, more and more bugs keep coming resulting in loss of business and credibility of the organization is affected. Lack of quality Ecommerce websites result in consumers moving back to the alternate methods of shopping or switching to another website. With the increase in the competition, companies have started studying the consumer behavior and determining the factors that affect the quality of Ecommerce websites form the consumers perspective. During these years, several lessons have been learned about the technology, business and economy of Ecommerce. -
Evaluation of Bending Stiffness of Transmission Line Conductors
Cables are made of helically wound wires and have a wide range of engineering applications. This thesis considers the use of such cables in overhead electrical power transmission lines. The loading on such cables is generally axial pull or tension and torsion. The oscillation of the overhead power transmission lines due to the wind or static bending in any applications, newlineintroduce an additional bending load on such cable assemblies and are subjected to varying newlinebending curvatures and results in reduction in bending stiffness. The effective stiffness of the cable assembly in its bent state varies widely between two extreme newlinebehaviours a monolithic infinite friction state offering the maximum stiffness and a newlinecompletely loose wire zero friction state offering the minimum thickness. Due to the wide variation of this extreme values, the estimation of the cable stiffness at any intermittent stage of bending has been quite challenging and is under continuous refinement. Though many mathematical models are stipulated in the last seven decades in cables, seldom they consider the influence of wire forces and moments about its normal, bi-normal, and axial directions together, in any analysis and evaluated the cable response. newlineThe dominant wire force and moments about the axial directions were never missed by many newlineauthors. Though the global behavior of the cable apparently seems to be all right even with the omission of some forces/moments, the mechanism of its constituent wires needs a fully proven scientific explanation that predicts the local behavior also correctly. The ultimate response of the cable will be complete when accurate theories are attributed for the global and local newlinebehaviours. Hence, this research work addresses the complete mechanics of the helically wound cables and considers the influence of wire forces and moments, in all the three directions, together in the newlineanalysis and evaluates the cable response. -
EVALUATION OF INFORMATION COMMUNICATION TECHNOLOGY PROJECTS FOR RURAL DEVELOPMENT
In India the ICT trend is in boom and as seen as hugely beneficial, and India is also been considered as the most preferred global destination foe outsourcing of IT and IT related activities after having said so it becomes important to use the benefits of IT to solve the prominent problem of India that is Rural development. Will the application of IT on this sector have the similar results? This study is based on the growing trend of information communication technology (ICT) based projects for development which is popularly known as ITCD. India being the hub for ICTD projects this paper attempts to evaluate the pros and cons of this developing system. It has been stated by many authors that most of the ICT projects are non-sustainable. This paper tries to examine the reasons for adopting this technology for rural development which is largely illiterate and the risks and reasons which lead to failure of such projects. Various organization like the government of India, International organizations and non-profit organizations have been investing largely in terms of finance as well as human resource. Is this investment worth the outcome is one major issue which the study looks into. In order to conduct this research qualitative tools have been employed. Interviews with experts were conducted and a case study was deeply analyzed. This paper presents a brief review of the technologies, the rural ICT projects and the issues associated with the use of ICT for rural development. -
Evolution of Virtual Prey using a Virtual Predator
Can evolution happen on a computer is it possible for Images to evolve? This paper tries to show that Mother Nature has got it right and evolution is the future for programs. How many times will a new release come to solve my previous problem and in the process create new problems! Evolution can happen on a computer is very clear in this work titled Evolution of a Virtual Prey using a Virtual Predator. The Virtual Prey can evolve its skin color based on an Artificial Intelligent Virtual Predator. Monochrome patterns have evolved very successfully. Some repeatable patterns in the Brodatz Texture Database have also evolved. Charles Darwin in his famous book Origin of Species suggests that evolution takes place using a method he termed Natural Selection. Survival of fittest has to be considered in context of the environment in which the species are living. One of the criteria of survival depends on whether the specie was able to propagate before it was hunted down by a predator. For example the skin color of a prey like an insect evolves to match the background it is living on such that the predators like birds and frogs will not detect them. Assume there are thousand insects on a surface and if nine hundred and ninety are eaten over a period of time are eaten. Then the last 10 will be those which have got skin color, pattern, and texture closest to the original. Some findings have been in the comparison of different genetic operators to evolve specie. Use of Mutation and Crossover operator is critical. Some level of continuation is required in the next generation to maintain and not lose the quality which has been already attained. The number of generations required depend on DNA length and on the correct use of these three parameters.. The runtime from thirty minutes has been reduced to ten minutes to evolve specie of 100 plus variables in the DNA of the images. If we are ready to run the program for a day on multiple machine in parallel then the possibilities of great diversity is very much possible. The predator will be an algorithm which tries to do a basic computer vision operation of correlating two images and ranking them. Then it eliminates a certain percentage of the population. The dissertation is broken down in chapters. Chapter 1 gives the Introduction and Chapter 2 gives an idea of what all research is happening in this area. Chapter 3 is the core content of my work and it shows the different approaches I have used to evolve textures, the use of different operators. This chapter is followed by the testing I had to do due to the complexity of the application and high chance of error creeping into the results. An idea of the application can be got from the Appendix where I have given a walk through of the Zing World -

Experience and Agency of Children with Intellectual Disabilities in Schools : An Ethnographic Study in Haryana, India
India currently has more than 24 million children within the age group of 0-18 years experiencing some form of disability. Among them, India has the highest population of children at risk of developmental disabilities (UNICEF, 2011). However, there is a significant dearth of knowledge regarding their lived experiences. Surprisingly, qualitative understandings of the lives of children with intellectual disabilities within their school environments are lacking in India. Thus, this research aims to fill this gap by focusing on comprehending the lived experiences and agency of these children within their schools, families, and neighborhoods. Recognizing them as social agents has the potential to challenge the marginalized status often attributed to them. The objective of this research was to understand the lived experiences of children with intellectual disabilities across various school setups, including government schools, private schools, and mainstream schools. Furthermore, it seeks to understand the values and perspectives of the schools, school authorities and teachers, and the manner in which children with intellectual disabilities employ their agency in their day- to-day lives within different educational structures. Ethnographic research was, therefore, conducted in four government schools, two private schools and two special schools in Karnal district, Haryana, India. Haryana was chosen due to the existence of previous research on the cultural understanding of disability in the state. A total of 25 children with intellectual disabilities and 44 school teachers were interviewed and observed. Classroom observations and shadowing also served as important methods of data collection. The findings reveal that policies, school structures and processes, as well as teachers' practices and attitudes, continue to perpetuate exclusionary practices for children with intellectual disabilities. The notion of "inclusive schooling" remains superficial within the Indian context. However, within these exclusionary systems and processes, a diverse range of differences were noted in terms of the experiences, beliefs, and preferences of children. These differences are influenced by a complex interplay of their social environment (school and home), cultural norms and personal attributes. Academic aspirations and experiences of personal friendship emerged as dynamic and intricate aspects of their lives. Evaluating these elements presents challenges as children's academic achievements and friendships are continually evolving, forming, and dissolving. Data analysis also demonstrates that children with intellectual disabilities not only actively construct meanings but also possess an awareness of the cultural context in which they exist. Their interactions with others, including the researcher, were heavily influenced by these cultural contexts. Their actions contribute differently to social and relational networks, depending on the barriers they encounter within each institution. The performativity of their agency was explored through an understanding of their "silences," which proved to be an essential element in analyzing their agency.Additionally, their agency was examined through their utilization of digital technologies which was actively used by children to maintain friendships with old friends, to develop new friendships and for entertainment purposes. This research, therefore, aims to integrate the notions of agency, culture, and structure in order to gain a comprehensive understanding of the experiences of children with intellectual disabilities in various educational environments in an Indian state. -

Experience of Resilience in Women with Breast Cancer : Implication for Resilience-Based Intervention
Breast cancer is prevalent among Indian women and affects their physical, emotional, and social well-being. Resilience in breast cancer refers to the ability to maintain newlinepositivity and adapt to challenges. However, evidence-based studies and theoretical newlineframework interventions on resilience in the Indian context are lacking. The current newlinestudy aims to explore the subjective experience of resilience and intend to provide resilience-based intervention in Indian women with breast cancer. The study also explores sociodemographic, clinical outcomes, relation with resilience, quality of life and posttraumatic growth in the Indian context. The study uses a qualitative approach with phenomenological paradigm to understand the patterns, processes and outcomes in exploring the concept of resilience. Purposive sample of 33 participants from two hospitals in Bengaluru, India were recruited. The participants consisted of 21 breast cancer survivors on follow-up, four on anti-cancer therapy and eight family members of breast cancer survivors for triangulation. Along with sociodemographic, clinical details, and the Connor-Davidson Resilience Scale (2003) to screen for categorising the resilience levels was collected. The in-depth interview guide was validated with experts to collect data. The interviews were tape-recorded, transcribed, and subjected to member checks, triangulation, intercoder reliability, and thick description to ensure the validity of the findings. The data was analysed using reflective thematic analysis by Braun and Clarke (2019). The finding describes four themes of experience of resilience in women with breast cancer. (1) Cancer diagnosis is a life-changing experience. Breast cancer diagnosis and therapy causes existential crisis, psychological distress, and social stigma. (2) Restoring healthy perception in an adverse event. Navigating challenges and achieving a balance between internal and newlineexternal factors. (3) Types of support-the pathway to resilience. -

Experiences of mindfulness-based relapse prevention on the smoking behaviour of working women
Smoking is the highest cause of preventable deaths in the world. The number of working women prone to addiction is high due to the levels of stress witnessed. The number of working women who have taken up to smoking has increased and is said to increase by 20 percent by the year 2025 if not addressed. Mindfulness, a Buddhist meditative technique helps with managing addiction to nicotine. Mindfulness based relapse prevention has showed promise to reduce relapse levels amongst people who smoke. The primary objective of the study is to check the experiences of mindfulnessbased relapse prevention (MBRP) on the smoking behaviour of working women in India. An embedded experimental design was carried out on eight working women who were selected using purposeful sampling. The participants went through eight two- hourly sessions of MBRP therapy, one session a week. Three sets of interviews (pre-intervention, mid intervention and post-intervention) were conducted including pre and post-test to check the levels of abstinence self-efficacy, mindfulness, perceived stress and craving. Follow up was carried out one week, one, two and six months post intervention. Thematic analysis was used for interpretation of qualitative data and paired sample t test was used for analysis of quantitative data. Themes that emerged were experiences with the habit of smoking, which included history of newlineinitiation, reasons for smoking, transformation seen and history of quit attempts. Four weeks into the intervention the themes that emerged were impactful components within self, supporting outcomes of practice and challenging experiences. Post the intervention experiencing changes, experiencing challenges through the intervention and strategies for abstinence and continued practice emerged. Mindfulness and abstinence self-efficacy had risen whereas craving and stress had reduced. Follow up at one week showed no changes in results. One and two months follow up showed newlinereduced practice hours of mindfulness with no full-blown relapse. -
Experiences of raising children with autism :
The purpose of the study was to address the gap in the literature related to fathers role and experiences in raising boys with autism in the Indian context. Though the study has tried to homogenise the sample to the best possible extent it does not aim to generalise the results; rather it seeks newlineto get an insight into some facets of the fathers experiences. A qualitative phenomenological approach was used for this study which addressed the three research questions: 1) What are the experiences of fathers before and after the diagnosis of autism? 2) What are the challenges that fathers experience as they raise their child with autism? 3) What are the personal changes that fathers go through as they raise their child with autism? Tied together these research questions sketches the journey travelled by the fathers and gave a sweeping picture of their overall newlineexperiences as fathers of children with autism. The study has mapped and constructed the passage of thirteen fathers of children with autism aged between six to 11 through a one on one interview. All the ethical newlineconsiderations have been followed. The participants were able to provide a rich and detailed account of their experiences of bringing up a child with autism. The analysis was done using Interpretative Phenomenologic alAnalysis. newlineSix major themes emerged from the study. They are 1) Making sense of early warning signs 2) The impact of diagnosis 3) Negotiating the social world 4) Accepting and accommodating autism 5) Personal transformations 6) Bonding with the child. One of the earliest behaviours noticed by all the fathers was a delay in speech. None of the fathers resisted going for a diagnosis. In fact, once they found that something was different in their child, they relentlessly pursued the reason for it. -

Explanations for anomalies in semi strong from of efficient market hypithesis
The tradition notion of efficient market described in the academic literature is quite strong and probably is unrealistic because of following factors: short selling, short covering, fresh buying and profit booking. After all, science is just a human idea about phenomena which can change over time. In real markets, traders can cause markets to be inefficient. According to verifiability newlinetheory of meaning, most of statements are meaningless such as prices reflect earning .in order to make a statement meaningful that statements have to be tested with all ideas related to it. Researcher is testing EMH under various conditions to make meaningful. In this study, researcher is testing so called semi strong under market condition and firm size which is based upon market capitalization. National stock exchange provides classification of companies based newlineupon market capitalization. This is an event study to study stock return to earning newlineannouncements in recession and post recession periods. In other words, testing so called semi strong under market conditions and firm size of market capitalization such as large cap, mid cap and small cap. Researcher uses AARs, CAARS and T-test to study the impact of earning announcements on stock returns. Result of this study shows its onerous to accept semi strong so Fama received the Nobel prize in economics for what?
