A Study on Vehicle Detection and Tracking Using Wireless Sensor Networks

引用

Wireless Sensor Network 2010年第2期2卷 173-185页

作者： G. Padmavathi D. shanmugapriya m. Kalaivani 不详

Wireless Sensor network (WSN) is an emerging technology and has great potential to be employed in critical situations. The development of wireless sensor networks was originally motivated by military applications like battlefield surveillance. However, Wireless Sensor Networks are also used in many areas such as Industrial, Civilian, Health, Habitat monitoring, Environmental, military, Home and Office application areas. Detection and tracking of targets (eg. animal, vehicle) as it moves through a sensor network has become an increasingly important application for sensor networks. The key advantage of WSN is that the network can be deployed on the fly and can operate unattended, without the need for any pre-existing infrastructure and with little maintenance. The system will estimate and track the target based on the spatial differences of the target signal strength detected by the sensors at different locations. magnetic and acoustic sensors and the signals captured by these sensors are of present interest in the study. The system is made up of three components for detecting and tracking the moving objects. The first component consists of inexpensive off-the shelf wireless sensor devices, such as micaZ motes, capable of measuring acoustic and magnetic signals generated by vehicles. The second component is responsible for the data aggregation. The third component of the system is responsible for data fusion algorithms. This paper inspects the sensors available in the market and its strengths and weakness and also some of the vehicle detection and tracking algorithms and their classification. This work focuses the overview of each algorithm for detection and tracking and compares them based on evaluation parameters.

Optimization of Ceric Ammonium Nitrate Initiated Graft Copolymerization of Acrylonitrile onto Chitosan

引用

Journal of Water Resource and Protection 2011年第6期3卷 380-386页

作者： A. shanmugapriya R. Ramya m. Venkatachalam P.N. Sudha 不详

In the present work, graft copolymerization of polyacrylonitrile onto chitosan has been carried out in the presence of ceric ammonium nitrate redox initiator. Optimization of grafting of polyacrylonitrile onto chito-san was performed by varying the process parameters such as ceric ammonium nitrate (CAN) concentration, polyacrylonitrile concentration and reaction time to study their influence on percent grafting and grafting ef-ficiency. The optimum reaction conditions obtained for grafting of acrylonitrile onto chitosan were reaction time 55 mins, CAN concentration 1% in Con. HNO3, and polyacrylonitrile concentration 0.75 mol/L. The characterization of the grafted products by means of FTIR, thermal analysis, X-ray diffraction and scanning electron microscopy furnished the evidence of grafting of polyacrylonitrile onto chitosan.

Water Quality Index and Absorption of Zinc from Electroplating Industry Effluent Using Fungi

引用

Journal of Agricultural Science and Technology 2011年第3期5卷 337-341页

作者： m. R. Rajan m. Periyasamy K. shanmugapriya Department of Biology Gandhigram Rural Institute Deemed University Gandhigram Tamil Nadu 624302 India

The present study deals with the Water Quality Index (WQI) and absorption of zinc from electroplating industry effluent using fungi. The physico-chemical parameters such as EC (Electrical Conductivity), TDS (Total Dissolved Solids), total hardness, magnesium, calcium, chloride, sodium, potassium, nickel, chromium and zinc content was above the permissible limits of BIS (Bureau of Indian Standards). The WQI was 13, which showed that the pollution level of the electroplating industry effluent was severe in the rating scale and the effluent was not suitable for disposal without treatment. Three fungal species such as Aspergillus niger, Peinicillium chrysogenum and Rhizopus nigricans were used for absorption studies. Different concentrations (25, 50, 75 and 100%) of electroplating industry effluent along with 1 gm of fungal mycelium with (1%) and without carbon source was incubated in a shaker for a period of 7 days in order to observe zinc absorption capacity. The absorption capacity of zinc was found to be higher in Aspergillus niger followed by Rhizopus nigricans and Penicillium chrysogenum. Among the three fungal species Aspergillus niger had high (50%) potential of zinc absorption with carbon source and low concentration (25%) of electroplating industry effluent.
