Advancements in technology are enabling us to look at new use cases in the methods of teaching, information sharing, knowledge dissemination, and self-learning. Learning environments are not only for teaching things to people., but also for providing more information to them on any subject that they may require from time to time. User friendliness can be enhanced with clever use of sensors to give hands free interactivity with the devices/gadgets. Context aware applications require sensors to get the context information. Mobile devices like smart phones and tablets today come with a hand full of sensors mounted on them which include one or two cameras, a microphone, a touch screen, an accelerometer to sense motion, and in addition have GPS and digital compass to provide location information to applications requiring these sensory inputs. The computational power packed in the processors used in these devices/gadgets including special support for graphics processing, the near general purpose computer like operating system environments, and the quality of cameras available, are all enabling application developers to map some serious computer vision based applications on today's mobile devices. This reality has encouraged us to get into development of Augmented Reality (AR) based interactive learning environments on mobile devices, leading to our development of a software framework for AR applications development and also development of an AR book and an AR board. AR has been called the eighth mass medium, after print, recordings, cinema, radio, television, Internet and mobile phones. There is ample scope for enhancing the learning/teaching experiences of the users with AR based learning environments. AR makes learning more effective and an enjoyable experience by providing more realistic information with the use of 3D graphics and animated models.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"803 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123914672","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 flow injection analysis-electrochemical quartz crystal nano-balance (FIA-EQCN) biosensor is presented for label free analysis of sulphadiazine residues in milk. The biosensor constituted a polyclonal antibody of sulphadiazine covalently immobilized to a gold coated quartz crystal mounted on a flow cell attached with FIA-EQCN setup. The biosensor showed linearity in the range 50 to 200 μg kg -1, with minimum detection limit of 10 μg kg-1, R2 0.97 and % R.S.D. 0.83. Good recoveries were obtained (98.6-100.5%) for sulphadiazine in the spiked milk samples. A good correlation was observed between the sulphadiazine concentrations measured through FIA-EQCN and the commercial ELISA kit. These results indicate that utilizing this system could be very effective to detect low level of sulphadiazine residues in milk.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"138 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128803450","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}

Several moisture measuring instruments are available in the market but for most of these instruments some sort of sample preparation is needed that involves shelling, grinding and weighing. The samples in this process are usually destroyed, and the measurement involves considerable time and labor. In this work, estimating moisture content (MC) of various types of grain, nuts, and bio-fuel materials from measurement of certain dielectric related properties of a parallel-plate capacitor holding samples of these materials between them at radio frequencies is presented.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121582867","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}

Much of the research is motivated by aerospace, biomedical and robotics industry where lightly damped flexible structures characterized by low frequency high magnitude are common. With the use of smart materials active vibration suppression becomes ease in various fields. In this work shape memory alloy (Nickel Titanium) wires are used as actuators for active vibration suppression of a piezoceramic laminated flexible cantilever beam, which is characterized by low natural frequency with closely spaced modes. Vibration control is experimentally performed at the first modal resonance frequency of the beam at which the magnitude of vibration is maximum. Pulse width modulation technique is adopted to control the actuation force through Matlab/Simulink via a data acquisition system. The aim is to implement a design based On-Off control rather than a model based control.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115225468","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 paper presents an unique approach for identification and classification of environmental contaminants by perturbing an electrochemical (EC) sensor with an oscillating potential rather than static voltage levels for extraction of statistically rich information from the current response. The dynamic response, being a function of the degree and mechanism of contamination, is then processed with a symbolic dynamic filter for extraction of representative patterns, which are then classified using a trained neural network. The approach presented in this paper promises to extend sensing power and sensitivity of these EC sensors by augmenting and complementing the sensor technology with state-of-the-art embedded real time signal processing capabilities.","PeriodicalId":367665,"journal":{"name":"2012 Sixth International Conference on Sensing Technology (ICST)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115436945","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}
