Using one-dimensional quantum dot approach on quantum box model, the transition of electrons from ground energy to a higher energy level (inter-band transitions) can be described by evaluating the time-dependent Schrödinger equation. By varying the dot size (1 nm, 2 nm, and 4 nm), different values of effective band-gap will be obtained. Using the perturbation theory, with dot size and light source variations, the power of the spontaneous emission can be obtained. With those variations, one kind of laser and an optimum dot size which can produce the highest spontaneous emission power can be acquired, that is by XeF laser radiation with 2 nm of quantum dot size.","PeriodicalId":395673,"journal":{"name":"2011 2nd International Conference on Instrumentation, Communications, Information Technology, and Biomedical Engineering","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114538599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, oxide conduction in γ-Bi2VO5.5 is modeled based on bond valence sum (BVS) method. In γ-Bi2VO5.5, there are oxide vacancies at the equatorial position in the perovskite-like layers. These vacancies can facilitate oxide movement. The γ-Bi2VO5.5 model was built in a primitive structure with the entire V coordination in one layer are tetrahedron and entire V coordination in the next layer are octahedron. Oxygen movement, based on BVS result, mainly occurs in equatorial site i.e. on [140] direction. The minimum achieved BVS value was 1.320, which is considered as a site that has large cavity and facilitates oxygen hopping.","PeriodicalId":395673,"journal":{"name":"2011 2nd International Conference on Instrumentation, Communications, Information Technology, and Biomedical Engineering","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132248030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A therapist flexes and extends the leg around the knee to eliminate the joint stiffness. The research is to design and develop a system of automatic Continuous Passive Motion (CPM) device so that patients no longer have to control it. The system will stop and return to its starting condition whenever there is patient pain. It is a force that is released by the patient in an opposite direction and will be represented as holding the DC motor shaft. A DC motor, H-bridge, microcontroller, and ADC modules are needed to develop this system. DC motor rotates clockwise with about 4V–5V as its voltage. If the DC motor receives load, the voltage will decrease and will be detected by ADC. The motor will stop if the voltage reaches 3V or less. After around 1.5s, it will rotate again with an opposite direction. The system is very sensitive to the patient pain, and if it is applied to CPM, it can improve patient safety.","PeriodicalId":395673,"journal":{"name":"2011 2nd International Conference on Instrumentation, Communications, Information Technology, and Biomedical Engineering","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133823288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are five pollutants material which is indicated as a source of air pollution, one of them is nitrogen oxide (NO2). The proper environmental monitoring system for air pollution management has demanding requirements. We have designed an integrated optical sensor to measure NO2 gas concentration using 1-D photonic crystal. The phenomenon of photonic pass band (PPB) has been used as a frequency filter in liquid concentration measurement. Photonic crystal, LED, and photodiode were designed to operate in NO2 absorption spectra that are in the range between 557.23 and 558.01 nm. The NO2 gas concentration is inversely proportional to intensity of peak PPB spectra. We built electronic signal conditioning circuit which is consisting of: current to voltage converter, voltage follower, active low pass filter, and instrumentation amplifier, to get an appropriate signal. The experimental results show that our optical integrated instrumentation is able to measure NO2 gas concentration, while requiring a filtering circuit addition because of the presence of internal noise.","PeriodicalId":395673,"journal":{"name":"2011 2nd International Conference on Instrumentation, Communications, Information Technology, and Biomedical Engineering","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134501715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Almost all devices equipped push-button or touch panel so that they can be operated by using finger easily. These interfaces are very useful and convenient, but still they have some drawbacks such as the fixed size, the squared shape, and the flat surface. Due to these restrictions, it is hard to add or to remove buttons when the number of commands is altered. To solve the above problems, we propose a new type of touch panel switch. Proposed panel can be stuck on an arbitrary bended surface, and be cut to arbitrary shape. Moreover the number of switch for one device controlling can be easily altered. Thus, it can be placed at various target objects existing in human living space. For examples, table, desk, chair, doll, handle of vehicle, pillow, and people's bodies etc. The method, experiments, and the results are explained in this paper. The demonstration shows the effect of proposed touch switch.","PeriodicalId":395673,"journal":{"name":"2011 2nd International Conference on Instrumentation, Communications, Information Technology, and Biomedical Engineering","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132445812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This motion estimation algorithm is block based, where all pixels within blocks share common motion probability distribution which leads to less effective side information generation.

Ten trial measurements were taken for each method. Descriptive analysis of both UTV 380 and DICOM were calculated. Computed mean and standard deviation for both measurements are 47.326±0.643345mm (UTV 380) and 47.099±0.377343mm (DICOM). Computed mean and standard deviation for 2D measurement is 46.290±0.455705mm.
