A prevalent technique to explore the underwater environment is ‘diving’. Underwater diving is considered to be a very dangerous as well as an adventurous task. The reason behind this is underwater environment is always varying in terms of temperature and pressure. Divers when dive through deep sea beds, heart beat and blood pressure keeps on varying. Sometimes they fail to inhale properly because they may not get sufficient airflow. In such cases, divers have to communicate with buoy station. But many times, the communication fails and divers die out of these issues. So a continuous monitoring of diver health is important where in diver can communicate and get the issues solved. There are many researches done on this issue. But none of them are up to the mark. This is the reason why we need a survey on this topic.","PeriodicalId":237016,"journal":{"name":"2017 International Conference on Technological Advancements in Power and Energy ( TAP Energy)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122606278","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}

Design and development of RF energy harvesting systems has renewed research interest in rectenna research domain. A rectangular cement substrate based patch resonating at 1 GHz is analysed for its receiving characteristics. The root mean square (RMS) AC voltage developed at antenna terminal (terminal voltage) upon plane wave incidence is the parameter under consideration. Simulated results employing High Frequency Structure Simulator (HFSS), are observed, and the voltages are in the range 0–5 mV. Experiments are conducted on a prototype structure with cement substrate, and the observed return loss and terminal voltage measurements are encouraging. A terminal voltage of around 5–7 mV is observed for direct plane wave incidence. In practice, direct RF energy incidence is unlikely. Nevertheless, the experimental results are encouraging, and further studies on available terminal voltage over a period of time needs to be undertaken. Development of cement based antennas provides a low profile front end implementation for rectenna systems, thereby enhancing implementation of RF energy harvesting systems in commercial and residential infrastructure.","PeriodicalId":237016,"journal":{"name":"2017 International Conference on Technological Advancements in Power and Energy ( TAP Energy)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128735083","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 inverter is modified from a dual buck inverter, and it retains the advantage of no reverse recovery of body diode. The DC voltage utilization rate can be increased by adopting the voltage commutation-bridge instead of the voltage-dividing capacitors in the inverter. Comparing with other dual buck inverters, this inverter has only one filter inductor, which reduces the volume and weight of the system observably and improve the integration. In the controlling method a combination of high and low frequency modulation is adopted to reduce the complexity of control and to improve the reliability and stability of the system. A feed forward loop is also incorporated into the system to make the output voltage constant irrespective of input voltage variation. The simulation of feed forward controlled dual buck full-bridge inverter is done using MATLAB/Simulink software. Arduino is used for generating control pulses for the switches and for implementing feed forward controlling loop.","PeriodicalId":237016,"journal":{"name":"2017 International Conference on Technological Advancements in Power and Energy ( TAP Energy)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127294346","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}

Switching sequences and timing signals for this method are derived from the two virtual PWM patterns. In this scheme only active switching states are used to control inverter. The proposed method is free from neutral point fluctuations and clamping diodes in comparison with CMV elimination methods for conventional 3-level inverter topologies.","PeriodicalId":237016,"journal":{"name":"2017 International Conference on Technological Advancements in Power and Energy ( TAP Energy)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124926705","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 Ideal case, the radial and vertical component of the magnetic field produced by the Ohmic transformer coil should be approximately zero at some specific location inside the vacuum vessel. Non-zero radial & vertical component of the magnetic field within the plasma region acts as error field and causes difficulties in the gas breakdown. The error field effect can be compensated by placing the transformer coils in series with the solenoid coil. These coil positions must be estimated precisely for designed plasma current inception. This paper proposes a method to optimize the coil positions in order to obtain the null position at the described location inside the vacuum vessel. After optimal positioning of the coils, the magnetic field and plasma formation are analyzed using ANSYS, EFFI, and Poisson codes. The analysis is conducted at Plasma Research Lab. The results obtained with ANSYS simulation is validated with Analytical calculations.","PeriodicalId":237016,"journal":{"name":"2017 International Conference on Technological Advancements in Power and Energy ( TAP Energy)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121671069","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 our study we used Online Labs theory and videos and incorporated CTML principles into it. According to CTML principle it will maximize learning without causing cognitive overload. The study sample was 58 students from an English medium secondary education school from south India. The experiment involves a control and experiment group where the control group is tested on content which does not adhere to CTML and the experimental group is tested on content designed based on CTML. A pre-test is conducted to assess the level of pre-knowledge in the subject and a post-test is conducted to assess the retention and understanding by students. This suggests that tablet content incorporated with CTML principle can lead to a deeper understanding of the subject.","PeriodicalId":237016,"journal":{"name":"2017 International Conference on Technological Advancements in Power and Energy ( TAP Energy)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123299045","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}
