Vision Based Calibration and Localization Technique for Video Sensor Networks

The recent evolutions in embedded systems have now made the video sensor networks a reality. A video sensor network consists of a large number of low cost camera-sensors that are deployed in random manner. It pervades both the civilian and military fields with huge number of applications in various areas like health-care, environmental monitoring, surveillance and tracking. As most of the applications demand the knowledge of the sensor-locations and the network topology before proceeding with their tasks, especially those based on detecting events and reporting, the problem of localization and calibration assumes a significance far greater than most others in video sensor network. The literature is replete with many localization and calibration algorithms that basically rely on some a-priori chosen nodes, called seeds, with known coordinates to help determine the network topology. Some of these algorithms require additional hardware, like arrays of antenna, while others require having to regularly reacquire synchronization among the seeds so as to calculate the time difference of the received signals. Very few of these localization algorithms use vision based technique. In this work, a vision based technique is proposed for localizing and configuring the camera nodes in video wireless sensor networks. The camera network is assumed randomly deployed. One a-priori selected node chooses to act as the core of the network and starts to locate some other two reference nodes. These three nodes, in turn, participate in locating the entire network using tri-lateration method with some appropriate vision characteristics. In this work, the vision characteristics that are used the relationship between the height of the image in the image plane and the real distance between the sensor node and the camera. Many experiments have been simulated to demonstrate the feasibility of the proposed technique. Apart from this work, experiments are also carried out to locate any other new object in the video sensor network. The experimental results showcase the accuracy of building up one-plane network topology in relative coordinate system and also the robustness of the technique against the accumulated error in configuring the whole network

Strategic factors on interpreting remanufacturing quality- Certifying framework to address warranty aftermarket for Malaysian industry

While the concept of remanufacturing is gaining popularity globally, literature and theory on strategic decision-making on certifying for warranty in this area remain limited. A strategic and establish concept flow is developed based on extensive literature review and surveys with experienced experts who are dealing with remanufactured, reconditioned, rebuilt and reused components. The remanufacturing research on evaluating quality assurance of remanufactured component targets macro-level parameters and the indicators which must be confirmed for evaluation. The strategic remanufacturing factors identified from the literature review are discussed in a brainstorming session with a number of remanufacturing researchers and academic experts. The study is further broadened by industrial surveys and case studies to justify the inputs on developing a framework to certify remanufactured components. Preliminary results have established the key factors of remanufacturing quality control that might lead to the strict quality assurance of remanufactured components. Later, the developed framework can be used as a benchmarking tool to certify remanufactured components and warranty issuance. The findings serve as the foundation for further research concerning Original Equipment Manufacturer (OEM) or Original Equipment Remanufacturer (OER) and Independent Equipment Remanufacturer (IER) in the Malaysian Remanufacturing Industry

Integration in Perspective: An ethnic-based analysis towards understanding the integration of immigrants in Sweden

Previous research has uncovered that immigrants from Somalia are one immigrant group that have struggled to integrate in Sweden. In light of this, I employ an ethnic-based approach with the intent to understand the difficulties that immigrants from Somalia encounter in Sweden by examining their own perceptions of integration. The study utilizes a qualitative case study approach and draws on data collected through semi-structured individual interviews and focus group discussions. The analytical framework of this study is inspired by Toumas Martikainen’s multi-perspective approach to integration in which integration is scrutinized from multiple angles and perspectives. Finally, the study puts forth that the subjective perceptions of Somali immigrants regarding integration could be better understood within the context of certain cultural and political features which provide explanations to the integration struggles and difficulties that Somalis face in Sweden. Finally, the findings of the research include that there is a clear deviation of understanding regarding the basic notion of integration among Somali immigrants that is contrary to that of the official Swedish government

Using WEDPI learning package to upgrade teacher's skills on information technology

The change in teaching techniques which applies information technology brings about a paradigm shift in our country's educational system. However, past researches have shown that the application of information technology in classrooms is still at an unsatisfactory level. This is caused by a group of teachers who haven't been able to master the basic skills of information technology application even after attending the courses. Therefore, the purpose of this research is to determine the level of skillfulness of primary school teachers - especially those in the interiors - on information technology, and thereafter develop a multimedia learning package (WEDPI Package for Learning) which will hopefully assist these weak teachers to increase their level of skillfulness in information technology. WEDPI refers to the productivity tools, which includes applications for word-processing (Microsoft Word), electronic spreadsheet (Microsoft Excel), database (Microsoft Access), presentation (Microsoft PowerPoint) and the Internet. This research adopted the quantitative approach and the ADDIE model was used in the development of this multimedia learning package. To obtain information on the level of skillfulness, the researcher carried out a hands-on test. The pre-experimental designs, which are the pre-test and post-test, were executed to determine if there were any difference in the level of skillfulness of the teachers after using the WEDPI Package for Learning. The research findings showed that teachers involved gave positive comments about the experience in using this stand alone learning material. The respondents also stated that the WEDPI Package for Learning is easy to use, flexible and is able to help them increase their level of skills in information technology. This is supported by the t-test results which show that there is a significant difference in the achievement of teachers' scores
