For classification purposes, support vector machine (SVM) was utilized. The purpose of our research is to provide additional information on rust conditions for reconfirmation use, prevent errors during rust evaluations, and to create a robust and practical rust evaluation system. For our methodology, we took photographs of steel structures using a digital camera and divided those images into smaller regions in order to calculate the evaluation parameters. The parameters themselves were determined by using a rust recognition process. We then used the classification results provided by evaluation experts and the parameters as SVM input vectors in order to classify rust conditions. As a result of our efforts, we developed an evaluation system with a correct classification rate of 99% for learning sets and a correct classification rate of 66% for test sets. The results we obtained suggest that the creation of a rust evaluation system using this method is possible.","PeriodicalId":6299,"journal":{"name":"2008 3rd International Conference on Sensing Technology","volume":"1 1","pages":"409-413"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82279833","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}

Gravity is a critical factor and its effects are usually included in the measurements obtained from accelerometers. This results in a need to eliminate gravity effects from the measurements in order to accurately determine the true acceleration of a moving object. In the present study, a new method has been proposed to estimate the gravity using the measurements from the existing INS sensors without employing any additional sensors. This significantly reduces the complexity of INS based system design. Two different types of models have been developed based on the proposed gravity compensation method to be used in Gyro-Based and Gyro-Free INS applications. The performance of both these models is illustrated by simulations and experiments. Results of simulations demonstrate that by including the proposed gravity compensation model, the errors in the acceleration measurements reduces significantly.","PeriodicalId":6299,"journal":{"name":"2008 3rd International Conference on Sensing Technology","volume":"81 1","pages":"218-223"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83874387","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 is mainly achieved by real-time control of camera parameters affecting the light exposure, i.e. camera gain, shutter speed and iris. Several other new strategies are also proposed to recognize and segment the person from the environment, and to reacquire the person when he is lost during difficult walking maneuvers. In addition to the camera exposure control, the camera pan and tilt, and the robot speed and steering are controlled based on the characteristics of the detected personpsilas image such as mass (area), centroid, and shape characteristics. The system has been implemented on a Segway robotic platform that has been equipped with a camera, an onboard computer, loud speakers, game-pad, etc. A video has been prepared that shows indoors and outdoors trials under a variety of conditions.","PeriodicalId":6299,"journal":{"name":"2008 3rd International Conference on Sensing Technology","volume":"1258 ","pages":"147-152"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91457176","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 term MI also has social and psychological implications, both as an indicator of a major health problem and as a measure of disease prevalence in population statistics and outcomes of clinical trials. In the distant past, a general consensus existed for the clinical entity designated as MI. In studies of disease prevalence by the World Health Organization (WHO), MI was defined by a combination of two of three characteristics: typical symptoms (i.e., chest discomfort), enzyme rise and a typical ECG pattern involving the development of Q waves. Biomedical sensors dedicated to acquire signals from cardiac instrumentation, even if sophisticated, cannot precisely reveal and help doctors to understand, at a glance, pathologies leading towards MI. This paper traces out an integrated algorithm based on a combination of level set evolution and variational approach according to Mumford-Shah model.","PeriodicalId":6299,"journal":{"name":"2008 3rd International Conference on Sensing Technology","volume":"21 1","pages":"457-461"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90694349","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 sandwich structure for flexible tactile sensor consists of top and bottom soft substrates made of Polystyrene, and in between of two soft substrates a piezoelectric thin film, PVDF, and a PDMS microstructures array are utilized as sensing material and microstructures, respectively. The experimental results showed the output voltage was linear with contact force from 10N to 0.5 N and good reliability within low frequency range 1 ~ 100 Hz. In addition, the shape recognition also can be achieved as the objective contacted with the 4 by 4 electrodes array. The effects of structural electrode on the enhancement of sensitivity were also numerically simulated by finite element method (FEM) and verified experimentally by dynamic measurement system, respectively. In general, the flexible tactile sensor developed in this study is not only applied for detecting contact force but also for the human physiology monitoring system, such as pulsation, heart rate and blood pressure, etc.","PeriodicalId":6299,"journal":{"name":"2008 3rd International Conference on Sensing Technology","volume":"36 1","pages":"504-507"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89951579","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}

These diaphragms are intended to establish the actuation mechanism for micropumps and similar microfluidic devices. The actuation method of the diaphragm relies on the electrostatic coupling between the diaphragm and the output Inter digital transducer (IDT) of the SAW device. In this paper, the theory governing the SAW device based novel actuation mechanism, is elaborated using the parallel plate approximation in electrostatic actuation. To validate the theoretical model, a finite element model (FEM) is developed using ANSYS simulation tools and presented. Different design methods are considered to enhance the deflection of the diaphragm for a low input voltage. As such, inclusion of corrugations around a flat square-shaped diaphragm and selection of different bio-compatible materials for various sections of the diaphragm are analysed at the simulation level. Deflection of the diaphragm is obtained as a function of the electric potential at the output IDT of the SAW device, and compared with results obtained from published research.","PeriodicalId":6299,"journal":{"name":"2008 3rd International Conference on Sensing Technology","volume":"54 1","pages":"125-129"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87210441","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}
