Server Initiated Model for Location Aware Web Application using Binary Search Tree
Location-based and Location-aware Services and systems are an integral part of a modern era of smartphones, faster internet, and all time connectivity. The usage of location awareness of a user and to accordingly provide him the necessary services is the core of the services based on mobile and desktop applications. In the push model, subscribers register spatio-textual subscriptions to catch their interests, and publishers post spatio-textual information or messages. This requires the location aware publishing of relevant notification and messages to the user. Such location aware publish services can be user initiated where a user types certain keywords to search for certain things around his area or can be server-initiated push model, where the messages and notifications are pushed directly by a server based on location and interest of users. In this research work, a novel searching algorithm based on binary search tree method has been proposed for location-aware server initiated model. To showcase the idea a small web application has been developed which asks users to allow location access and based on that the relevant shopping offers are displayed to the user. This helps the retail shops to regularly update their offers to attract more customers increasing their footfall and sales.

Typology of Retractable Roof Structure
Retractable roof structure is mostly used in a stadium and sports complex. Roof is helped to protect structure from various climatic conditions, it provides maximum circumstances to facilitates various activities. Which are designed with stadium and sports hall. Retractable roof structure gives quality atmosphere as well as remembrabal experience to the visitors. Retractable roof structure is the best structure which permits sunlight and ventilation. It gives required atmosphere to the ground. Retractable roof structure which can be fold level by level, the folding feature of retractable roof structure enhance the effectiveness and efficiency of whole structure. Now, we research different system and identity characteristics of retractable roof structure and it can be moving system or folding structure.

Analyzing the Performance of BER and SER in an Equilized OFDM System over AWGN by Using 16, 64, 128, 256 QAM Modulation
For wireless communications system, Orthogonal Frequency Division Multiplexing (OFDM) is a widely applied technique. This system also enables simple filtration or equalization by cyclic prefix insertion. The sensitivity of single-carrier systems to carrier frequency offset (CFO) is much lesser than that of OFDM systems. In present OFDM standards, such as IEEE802.11a/g or DVB-T, preamble (or pilots) is used to estimate and compensate the carrier frequency offset (CFO) and channel impulse response. There is a considerable problem i.e. the residual carrier frequency offset still destroys the orthogonality of the received OFDM signals after the CFO estimation and compensation. This situation further worsens the bit error rate of OFDM systems during the equalization process. In this research work, an equalized OFDM system over AWGN noise by using 16, 64, 128 and 256 QAM is designed. The designed system is modified by using QAM mapping at transmitter and receiver ends. Also, normalization of transmission bits and de-normalization of received bits is done for decreasing BER and SER. Performance analysis of designed OFDM architecture with ZF equalization is performed by using four efficient modulation indexes (16, 64, 128 and 256) with M-QAM modulation. Whole analysis is implemented over OFDM model with AWGN noise. Here the OFDM architecture is used to reduce noise (can be inter-symbol interference) which is the most important loss or attenuation in optical signals, thus mapping and equalization (filtering) is performed. After implementation of proposed method, we have evaluated the performance of the same by using Symbol Error Rate (SER) and Bit Error Rate (BER). These parameters are calculated and plotted with respect to input SNR. MATLAB R2013a has been used as an implementation platform using generalized MATLAB toolbox and wireless communication tool box.

A Review on Recognition of Indian Handwritten Numerals
This paper presents a detailed review of various handwritten numeral recognition of various Indian languages. Character recognition is a field of pattern recognition which is in active research for the past few decades for its vast fields of application and still remains a challenging topic for research. Handwritting recognition is one the applications of Character Recognition. Various hand writing recognition for Indian languages has been under research in the past few years. The major challenges with handwritten character recognition is that the non-uniformity in the writing style of character, different styles of writing the same character, smoothness of the curves of the character and similarity between two characters. Several techniques have been developed to recognize Indian Numerals and have varying recognition rate. Some of the techniques are discussed below.

A Study on Working Capital Management in Apgenco Ltd., Muddanoor, Kadapa(D)
Working capital management plays a significant role in better performance of business entities. This study analyzes the influence of working capital management on RTPP Ltd. The manufacturing firms are in general facing problems with their collection and payment policies. Moreover, the financial leverage, ratio of current asset to current liability and firm size also have significant effect on the firm’s profitability. The effective policies must be formulated for the individual components of working capital. Furthermore, efficient management and financing of working capital (current assets and current liabilities) can increase the operating profitability of manufacturing firms. For efficient working capital management, specialized persons in the fields of finance should be hired by the firms for expert advice on working capital management in the production sector.

A Hop To Hop Energy Efficient Transmission for WBAN (Wireless Body Area Network)
It is a familiar fact that conservation and preservation of network energy is one of the primary objectives of the sensor nodes in a wireless sensor network. This becomes even more important when we are talking about Wireless Body Area Network (WBAN). In this case, the sensor nodes are working either very close to or inside a human body. Hence performance is a very important task here. In this project we aim to reduce the consumption of energy while a transmission is made. We tend to strategically toggle between working/non-working status of a sensor node while it is being involved or not involved in the transmission process. This was, we are able to increase the network time by a very good amount. Other deceptive parameters are also to be calculated. With the advancement in technology, we now have access to wearable physiological monitoring system. In this concept, an individual will wear a fabric in which a collection of sensors will be embedded. All these sensors will be connected to a central monitoring system. Sensors will continuously send data to these central monitoring systems. Hence, wireless sensors are now being used as wearable gadgets. But the limitation here is that they have very limited amount of energy. And when it comes in medical terms, every fault in an instrument can be a factor in determining the cause of a healthy life or an unnoticed illness. Hence, it becomes very important to work on these sensors and give them a long lifetime so that their monitoring does not get affected. There are many ways we can achieve this. Good amount of research has been done in this domain. We here are working on an algorithm in which a sensor node will be strategically switched on and off based upon its usage. This way, only the appropriate amount of energy will be used by the sensor and overall energy of the complete system or network will be preserved on a larger extent.
