Most biometric characteristics remain constant after they are fully developed. The hopes on biometric systems are in many respects justified and their use frequently gives good results. Fingerprint based biometric systems offer positive identification with a very high degree of confidence and compact solid state fingerprint sensors can be embedded in various systems. Fingerprinting does not require a laboratory for analysis, and fingerprints remain relatively constant over time, with the exception of injury. Each person has ten fingers, ten unique tokens tied to his or her identity. In this thesis, our objective is to design a fingerprint-based biometric system which is capable of achieving a fully automatic \"personal identification\" with a high level of confidence based on fuzzy sets in real time. Primarily the ends, branches of ridges and valleys of fingerprint are scanned. These points are unique for every person and are used to match fingerprints by their location. The following topics are covered: introduction, image requirements in acquisition and specifications, image noise reduction and enhancement, image processing methods, matching procedures and the conclusion.","PeriodicalId":161669,"journal":{"name":"2007 International Symposium on Micro-NanoMechatronics and Human Science","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123714692","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}

An interdigitated array (IDA) electrode with four independent microelectrode subunits was fabricated with indium-tin-oxide (ITO) and used as a template to form cellular micropatterns. A suspension of C2C12 cells was introduced into the device between the upper slide and the bottom IDA. In the present system, the n-DEP force is induced by applying an ac voltage (typically 12 Vpp, 1 MHz) to direct cells toward a weaker region of electric field strength. The cells aligned above one of the bands of IDA within 1 min since the aligned areas on the slide were regions with the lower electric field. The application of an ac voltage for 5 min allows the cells to adsorb onto the cell culture slide. After disassembling the device and removing excess cells, the culture slide was assembled again with the IDA electrode, and was rotated 90deg relative to the previous setup. The second cell type was patterned in lines using the same method as with the first set of cells, forming a grid pattern on the slide.","PeriodicalId":161669,"journal":{"name":"2007 International Symposium on Micro-NanoMechatronics and Human Science","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117349285","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}

The parallel typed two-axial actuator was composed of two bimorph piezoelectric elements and two small links connected by three joints. We formulated kinematics for the parallel typed two-axial actuator because the endpoint is controlled in the two-dimensional coordinate. Since relationship between applied voltage and displacement cause by the voltage shows a hysteresis loop in the bimorph piezoelectric element used as components of the two-axial actuator, we produce a control system for the two-axial actuator based on a multi-layered artificial neural network to compensate the hysteresis. The neural network is comprised of 4 neurons in the input layer, 10 neurons in the hidden layer and ones neuron in the output layer. The output neuron emits time derivative of voltage; two bits signal expressing increment or decrement condition is generated by two input neurons; one of the other two input neurons and the other calculate current values of voltage and displacement, respectively. The neural network is featured with a feedback loop including an integral element to reduce number of neurons. In the learning process, the network learns the hysteresis including a minor loop. In the verification test, the endpoint of the two-axial actuator traces the desired circular trajectory in the two-dimensional coordinate system.","PeriodicalId":161669,"journal":{"name":"2007 International Symposium on Micro-NanoMechatronics and Human Science","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131542318","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}

The size of GUVs is comparable to that of real cells (~10-100 mum). Thus, GUVs are employed to construct artificial cell models, which are reconstituted from biochemical materials to mimic real cellular functions in a simpler manner for investigation of fundamental mechanisms of living systems. However, transmembrane proteins are difficult to reconstitute on GUV bilayers. In order to obtain GUVs containing transmembrane proteins, giant proteoliposomes, here, we introduce the novel method using membrane fusion between GUVs and recombinant baculovirus (Autographa californica nucleopolyhedrovirus (AcNPV)). It is known that the AcNPV budded virus (BV) displays recombinant membrane proteins on their own envelopes. BVs have fusogenic envelope glycoproteins (gp64) sensitive to acidic pH. Combination of these two features may produce giant proteoliposomes. The fusion properties were observed using fluorescence microscopy to comprehend conditions suitable for reconstitution of proteoliposomes. The display of a 7-fold transmembrane receptor protein (G protein-coupled receptor) on GUVs was also demonstrated using fluoroimmuno microscopic observation.","PeriodicalId":161669,"journal":{"name":"2007 International Symposium on Micro-NanoMechatronics and Human Science","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125558214","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}
