Primary function of this system is to regulate gas concentrations in the Blood. It is modeled by Nonlinear Delay Differential Equations. Several dynamical models for respiratory regulation are available in the literature, which are broadly classified as Comprehensive and Minimal Models. Minimal models are derived from the comprehensive models with some assumptions and are linearized for simplified analysis. Current literatures in these mathematical modeling approaches are directed towards describing pathological conditions, giving little thrust for the prediction. Analyses of these systems are not straightforward because of the variable time delay. From the system's point of view, increasing delay makes the system oscillatory. Physiologically, delay depends on the blood flow. In this model, delay in feedback loop of alveolar oxygen and carbon dioxide partial pressures make the system oscillatory, causing discomfort or fatal to the subject. Present analysis is motivated to find out the range of delay for comfortable operation of the system.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121534462","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 healthcare insurance is one of the cost-effective solutions to control the out-of-pocket expenditure in the sector. Nevertheless, the existing information asymmetries in the field of healthcare insurance bewilder the potential client in selecting the right policy. They are more dependent on the business agents for information and the chances of being exploited become high due to the imbalance in the information. This paper proposes an information system that makes use of semantic Web techniques to minimize the information asymmetry in Indian healthcare insurance market. The emerging concepts of semantic data mining encourage the cooperative way of existence and reduced chances of exploitation of the client or patient.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126872526","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}

Detection of reflected ultrasonic waves from body tissues requires low noise amplifier with wide input dynamic range. The transducer, being capacitive, isolates dc voltage from the input of the amplifier necessitating additional biasing circuit. In this work, a differential amplifier topology is chosen for its ability to reject common mode interference. Biasing is done by low frequency feedback using CMOS transistors which do not add significant noise to the system. The amplifier is designed in 0.18 μm CMOS process. Its input referred noise is 24.3 μV rms in the band 1-15 MHz. At 10 MHz it provides a gain of 25.5 dB with an input dynamic range of 62.5 dB. The amplifier consumes 314 μW of power with 1.8V-GND supply.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132806692","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}

Proposed sink mobility scheme increases network throughput as well as conserves energy by optimal path construction. The proposed scheme divides whole network into sub regions, and they are coupled with quad tree. Mobile sink collects data region wise.

Cloudlets can be used to provide such services with wireless LANs. However, the device mobility is limited to that network. Hence, Mobile Cloud Computing leaves two serious challenges, mobility and energy efficiency. This paper proposes a model to tackle the issues in new direction. In order to support mobility of the device, various parameters like signal strength, bit rate, number of interactions between Cloudlet and mobile device are measured to evaluate the handoff conditions. Further, various decisions are made based on two factors, offload factor and risk factor, to optimize the energy usage. Fuzzy based approach is used for offloading decisions. The proposed model and algorithm were evaluated using “opennebula” based Cloud setup and related experimental results were reported.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133614667","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}

Thus, the need for fault tolerance and reliability of deployed systems becomes increasingly prominent. This paper discusses fault tolerance and reliability observed in the design of a parallel self-healing VLSI system, based on partial dynamic reconfiguration (PDR) and built-in-self-test (BIST) for delay/stuck-at faults. PDR is employed to keep the system on line while under repair, for reduced power consumption and also to reduce repair time. Results prove that, a self-healing FFT prototype system implemented on Virtex6 FPGA can tolerate stressful sequences of injected delay and permanent faults with nominal impact on the system performance (hardware overhead and delay). The review of research proves that the proposed system is ideal for VLSI implementations of low power application fault tolerant systems.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131809855","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 set point weighting factor is calculated online according to the process change of error through a simple sigmoid function.

The proposed dynamic set point weighted PID controller provides a significant amount of performance enhancement for higher order processes with dead time. Its superiority has been verified through simulation study as well as real time implementation.

On exploring the different teaching methods adapted by teachers in Indian schools, lack of interactivity and increasing disinterest was exposed. In order to overcome this, the focus was to introduce a fun and interactive environment in schools. While interviewing school students it was found that they face difficulties in visualizing the 3D solid shapes during blackboard teaching sessions. Hence, they are not able to grasp all the facts taught in the class. The design opportunities gathered after primary research lead to the key facts of this project. The target audience was middle school children and the aim was to teach 3D shapes such as cube, cuboid and cylinder using TUI (Tangible User Interface). The design constituted of tokens with fiducial markers, which were used as educational tools on interacting with the tabletop interface. The outcome of the design motivated students for viewing, sharing and presenting the concepts behind the 3D shapes.","PeriodicalId":265072,"journal":{"name":"Proceedings of the 2014 IEEE Students' Technology Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115932271","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 a fixed frequency hysteresis current (FFHC) controller, which is implemented on the basis of sliding mode control (SMC) technique and fixed frequency current controller with a hysteresis band. The controller retains the benefit of hysteretic current control having fast dynamic responses and mitigates the drawback of the variable switching frequency. These have been verified and compared with the carrier based pulse width modulated (PWM) voltage controller under the same load fluctuation. The proposed method is then applied to 6-KVA, 220V, 50Hz islanded 1-Φ voltage source inverter (VSI) system. The results show that the dynamic response is quite faster than that of widely used PWM-controlled inverter systems.
