The main goal of this paper is to compare various person detection approaches used in video surveillance applications. Over the last decade, person detection has made remarkable progress. The paper gives an overview of some of the successful techniques for people detection. In this paper we discuss about the current methods involved in human detection in fixed cameras used for surveillance purposes. Sliding window approach scans the image at all relevant positions and scales to detect a person. There are two stages in part based methods. First uses low level classifiers to identify the parts and second connects based on specified topology.

Groundwater is an important source of drinking water supply throughout the world. WQI, a technique of rating water quality, is an effective tool to assess spatial and temporal changes in groundwater quality. Fifty groundwater samples were collected from dug wells and bore wells during the pre monsoon season. Water quality index rating was carried out to quantify overall groundwater quality status of the area. The values of WQI have been affected mainly by the concentration of dissolved ions in ground water. The values of WQI of the samples were found in the range of 61-1933. The majority of groundwater samples fall in Poor (40%) and Unsuitable (34%) category indicating groundwater not fit for drinking purposes. Because of the highly industrialized area, the impact of natural sources of contamination is as same as anthropogenic activities.

Wireless Sensor Network (WSN) is an emerging and very interesting technology applied to different applications. They are formed by little, self-deciding sensors that cooperate to form a large scale network with thousands of nodes covering a large area. Clustering the sensor nodes is an effective technique for achieve the energy efficiency of the network. Current clustering schemes utilize the two Passive Clustering schemes that create a hierarchical control structure for the clusters in the Wireless Sensor Networks; selecting the cluster heads with more residual energy, and rotating the cluster heads periodically to distribute the energy consumption among nodes in each cluster and prolong the network lifetime. The proposed system is Enhanced ACK Aware Clustering mechanism, called EAACM, to provide persistent routing path in Wireless Sensor Networks. The EAACM introduces the Predicted Routing Path to assist in constructing the cluster head and gateway nodes. By determining the suitable Predicted Routing Path of the nodes in the cluster, the energy efficiency of the routing path will be increased, and by using the enhanced channel aware technique called ACKnowledgement Aware Detection for secure routing. An AAD uses the passive malicious node detection method, by measuring the time occurrence of ACK packets that are received by the source node. EAACM proposes the suitable efficient path for the ACK packet that increases the Energy-Efficiency and Secure-Routing by using ACK Aware Detection in Wireless Sensor Network. In AAD the ACK packet is sent after every node routing and also CH routing. If the ACK packet is delayed by the predefined time then the node is considered to be the malicious node and also that node will be avoided when routing. In case of the CH malicious node the next CH node will be elected according to the possible node from another possible route using the path provided by the PRP.

This paper mainly aims on the idea for the pothole detection system. This paper addresses some of the key steps and some of the challenges of the detection system. It reviews various types of software and hardware of various levels currently used. We also have proposed an algorithm which could computes the working of the whole system in short. We have come up with a low-cost, road-surface-monitoring method, which employs acceleration sensors mounted on public transport buses, as a viable solution to this problem. According to this method, the sensors record vertical and horizontal accelerations experienced by the vehicle on its route while a GPS device separately logs its corresponding GPS coordinates. The collected data can be then processed to locate potholes along the path traversed earlier by the vehicle.[2] This system also takes care of alerting the government authorities about a pothole or bad road on its own. Every time a commuter passes over a pothole the government will be alerted until and unless they come and repair that road.[3] In the conclusions, questions still open and opportunities for future research are discussed.

This paper proposes a novel framework for commendably ascertaining frequently accessed data items over a wireless XML broadcasting scheme. A proficient XML dissemination scheme is used for supporting twig pattern queries in the wireless environment. Twig pattern queries that contain intricate conditions are quite common and critical in XML query processing. The mobile client can retrieve the required data satisfying the given twig pattern by performing bit-wise operations on the Lineage Codes in the relevant G-nodes. Counter-based algorithm tracks a subset of items from the input, and monitor counts associated with these items. It decides for each new arrival whether to store this item as frequent item or not. The proposed framework is reliable, efficient and user-friendly.

The world has been revolutionized with the introduction of automation in almost all productivity, decreasing costs of manufacturing, improving quality and more importantly upgrading of working condition of the human labour. As we all know that water is very fragile natural resource which is very essential for every individual. So it’s become very mandatory to handle water properly in sophisticated way. Earlier water was supplied in metropolitan area’s was not so automated. So it becomes unprecised and water was not managed properly as per the requirement of various zones as they were mostly manually operated which results wastage of water. With the help of Programmable Logic Control (PLC) we have developed automatic control of Elevated Service Reservoir (ESR) which was previously done manually which leads to wastage of water in great extent. It not only controls but also it monitors whole process with the help of Supervisory Control and Data Acquisition (SCADA)

The sub synchronous resonance (SSR) phenomenon may occur when a steam turbine-generator is connected to a long transmission line with series compensation. The main purpose of this work is to verify the capability of the gate-controlled series capacitor (GCSC) to mitigate SSR. For this study the GCSC was tested in conjunction with the IEEE First Benchmark Model. The actual possibility of controlling SSR was verified by digital simulation using the Alternative Transients Program/Electromagnetic Transients Program. As a result it was shown that GCSC can damp SSR even without a specific control. It was also shown that, using a simple controller, SSR as well as electromechanical oscillation can be damped.

Several mechanisms for adaptive transmission of multimedia data, which is based on real time protocols RTP/RTCP.RTCP offers capabilities for monitoring the transmission quality of multimedia data. When multimedia data (audio, video) are transmitted over a network with low Quality of Service Management there is a high possibility of router queue overflow. To overcome this problem Adaptive Transmission Rate Algorithm is used. To do this Packet size of each source is adjusted according to network bandwidth. A controller is used to trace the data transmission rate at the router. An algorithm is developed and coded in Tool Command Language. Simulation is performed on NS2. The present work is developed using JMF over RTP only.

The idea of using the mobile phones is to deliver the valuable services except the basic communication that had been started in the early 1980s when the Internet was added in the Voice Telephony. In this application first you need to add your task in the To-do List with the places (like Bank work, withdraw money from an ATM etc.) then this application searches nearby places defined by you and generate a voice message of your work as our reminder. Your friends can add their To-do List in your list if you allow them and if they are added to your friend’s list. With this application we can search our favourite places within our vicinity, along with complete place address and how far it is from where you are.

Compensators are used in place of classical PID controllers for possible achievement of better performance. Highly oscillating processes require more effort in selecting proper controllers or compensators. In this work a novel compensator based on a series proportional controller and a feedback lag-lead compensator is proposed and applied to control a process having 85 % overshoot and about 6 seconds settling time. The proposed control scheme uses the gain constant of both the proportional controller and the feedback lag-lead compensator to control the steady-state characteristics of the closed-loop control system. The proposed controller-compensator is tuned using MATLAB optimization toolbox. It was possible with the proposed scheme to satisfy a system performance with only 0.0993 % overshoot and a settling time of 0.3886 seconds and steady-state error as low as 0.05 for a unit step input. Comparison with classical a PID tuned control was in favor of the proposed compensator.

The mechanical properties of epoxy and polyester matrix composites reinforced with Jute/Hemp fibres were evaluated. In this research the mechanical properties like impact strength, tensile strength and flexural strength were studied. These fibres were placed with matrix resin in different orientation (30%, 45%, and 90%) by using simple hand lay-up technique. The evaluation of the results show that the mechanical properties are higher in the 900 oriented hybrid composite than in 450 and 300orientation. There are indications that by the incorporation of both fibres the polyester resin will stabilize mechanical properties than epoxy resin.
