A controller is designed which is serving the purpose of voltage control and damping of power oscillations.

The proposed electronic ballast uses a Cuk buck-boost ac-dc converter in continuous conduction mode (CCM) as a power factor preregulator. In this electronic ballast topology, a self oscillating half bridge series resonant parallel loaded inverter (SRPLI) is used for the conversion of dc to high frequency ac voltage. The design, modelling and simulation of this topology is done in MATLAB-SIMULINK environment for a 18W, 220V, 50Hz compact fluorescent lamp. The zero voltage switching (ZVS) is achieved which reduces the switching losses. The power quality indices like total harmonic distortion of ac mains current (THDi), power factor (PF) and crest factor (CF) are evaluated to demonstrate the behaviour of proposed electronic ballast.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"25 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125764796","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 combined classification approach using K-Nearest Neighbor classifier and Minimum distance classifier is developed to predict the class label of the unknown sample. Experiments are conducted on electric component images which are rotated between 0° to 360° angle.

Since location based services (LBS) are one of the major applications of the AR, it is important to have a privacy-aware management of location information, providing location privacy for clients against vulnerabilities or abuse. This paper discusses how to protect the location privacy from various privacy threats, which occurred because of the unlimited usage of LBS, by a scalable architecture. We have developed an efficient LBS privacy protection algorithm. In our model, k-anonymization and pseudo-anonymization methods are used hand in hand. The proposed location privacy frame work is implemented by an efficient trusted third party server. We have studied the efficiency of our algorithm under different conditions using realistic work loads. Our experiment shows that the k-anonymization and the pseudo-anonymization methods used together in our algorithm provide an efficient location privacy.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131983387","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 proposes a novel low-cost technique to compensate for the temperature dependence of piezoresistive sensor configured in a Wheatstone bridge. A calibration algorithm is established by relating temperature and pressure sensor readings at three different temperature ranges. The test result shows that the signal conditioning method provides thermal error less than 0.25% in the compensated temperature ranges −10 °C to +70°C. The obtained results show the offset compensation is up to 50 mV and sensitivity is of 250 mV/bar. These results are discussed and found comparable with reported data. Sensor repeatability and process repeatability were tested. The digital process of temperature compensation using software and hardware is discussed.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128266768","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 India, there are many such villages which have been electrified through renewable isolated power plants like biomass gasifier and solar photovoltaic (PV) systems. Case studies have been conducted for such a biomass gasifier based isolated power plant in the state of Maharashtra, India. This paper discusses the various power quality measurements taken at site during its operating hours. It has been observed that the large unbalance and high THD (Total harmonic Distortion) in voltage and current leads to excess heating of motor loads and over head line conductors in the network. The measured data shows that some improvements in the power quality of isolated power systems are required to bring it on par with grid power supply.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114339167","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 current multiplier approach with average current control is employed for PFC controller which is designed for continuous conduction mode (CCM) of operation. For the control of current and torque in the PMBLDCM, a rate limiter is designed in the reference voltage at DC link. Detailed design, modeling and performance of the proposed drive are presented for an air-conditioner driven by a PMBLDC motor of 0.817 kW, 1500 rpm rating.
