In particular there are 3 main contributions: First, a novel sensors selection algorithm based on the concepts of entropy and information gain from information theory is developed, to reduce the number of sensors without affecting, or even improving, model accuracy; Second, a novel tec

Urban warfare is unfortunate reality of the modern world and that fact is unlikely to change in the near future. One significant danger to soldiers in an urban setting is posed by concealed snipers. The large amount of cover among densely packed buildings make snipers hard to detect by sight or sound. When a sniper fires at troops, it is imperative to positively locate the sniper as soon as possible to ensure the safety of soldiers in the field. One method of sniper detection is the use of distributed sensor nodes. These nodes may be stationary, mounted on a soldier or mounted on a ve

Abstract:

Epigenetic phenomena are essential for the regulation of gene expression and consequently, cell fate. At the forefront is the methylation of DNA at cytosine in CpG nucleotides, which causes histone remodeling and eventually leads to gene repression. This is particularly important in cancer, as DNA methylation is used to repress tumor suppressor genes. Our purpose is to develop a rapid and direct approach for detecting DNA methylation to enhance DNA diagnostic systems.

Abstract:

碩士<br>國立臺灣科技大學<br>資訊工程系<br>100<br>Wireless sensor networks have been used in many applications. One of the most important applications is to detect a target or an event in the monitored region. However, most of previous target detection studies are based on the unrealistic disk model, and use a single sensor’s decision as the decision of the overall network. This simple detection scheme may result in high false alarm probability and deteriorate the detection performance. Therefore, data fusion is required to improve the performance of detection. It has been broadly exploited to alleviate the i

Abstract:

碩士<br>國立清華大學<br>電子工程研究所<br>100<br>Liver cancer is usually the No. 1 of the top ten causes of death in Taiwan. Many studies have found that the breath ammonia level is significantly higher in chronic patients with liver disease（> 0.7 ppm）than that in normal people. Therefore, the detection of ammonia concentration in exhaled breath becomes more and more important. In this work, we used ultrathin indium nitride (InN) epilayer（~10 nm）to fabricate gas sensors for the detection of ammonia with sub-ppm level. Furthermore, we used curve fitting to distinguish different ammonia concentration and tried

Abstract:

Biological/biochemistry analyses traditionally require bulky instruments and a great amount of volume of biological/chemical agents, and many procedures have to be performed in certain locations such as medical centers or research institutions. These limitations usually include time delay in testing. The delays may be critical for some aspects such as disease prevention or patient treatment. One solution to this issue is the realization of point-of-care (POC) testings for patients, a domain in public health, meaning that health cares are provided near the sites of patients using well-designed

Abstract:

碩士<br>中華大學<br>資訊工程學系(所)<br>96<br>In general, large amount of cameras are demanded to surveil a large building or area but this may introduces a high data transmission rate and computation cost. The reason why a high data transmission rate is required is that no matter what a event occurs the video bit stream form the cameras are transmitted continuously. In this study, a location-aware system using the sensor network is developed and then cooperated with the vision-based surveillance system to construct a new sensor-based surveillance system. When the location-aware system detects an event, th
