For this it is necessary that movement is modelled effectively. In this paper we propose an emergency scenario movement modelling by managing the co-ordination task by a four way directional movement. The communication between the stages is considered to be provided by a MANET based network setup, since they are easy to deploy and do not require elaborate infrastructure. Mobility of MANET nodes between the stages has been modeled with random waypoint mobility model (RWM). Performance of the scenario is analyzed for three routing protocols viz. LAR [1], DYMO [2] and AODV [3]. Packet delivery ratio, end to end delay, normalized routing load and data packets forwarded is estimated for these protocols. From the results it is observed that for such situations, performance of geographic routing protocols is better than other reactive protocols.","PeriodicalId":229600,"journal":{"name":"2014 Recent Advances in Engineering and Computational Sciences (RAECS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114995293","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}

By annealing at 500°C, the structure has changed from amorphous to the anatase crystalline state. The phase transformation from anatase to rutile was observed in the temperature range 600-700°C.

This panel gives the dc power which can be directly used in dc power application. In our daily life we generally work with ac load. Hence an inverter is proposed in this paper which will provide a robust operation and very simple to implement. A hysteresis current controlled inverter is proposed with fixed band and the value of the load variation is determined with output current THD lower than 5%. Inverter is developed with three level techniques. Maximum power tracking of panel power is done by constructing artificial neural network. System performance is measured in terms of the efficiency of the MPPT controller and flexibility in the inverter operation for standalone load.","PeriodicalId":229600,"journal":{"name":"2014 Recent Advances in Engineering and Computational Sciences (RAECS)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126655328","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}

It uses very narrow pulses, of the order of a few nano-seconds, in order to have very high data rate communications. These narrow pulses spread the energy over a wide frequency band, and hence the name ultra-wideband (also called Impulse radio). As one of the major concern while choosing a pulse shape for UWB communication is that it should meet the FCC emission mask requirements. So In this paper, we will study the spectral properties of UWB pulses. Firstly we analyze the UWB Pulse Generation and Power Spectral Density (PSD) of the Gaussian monocycle and then extends our study for finding optimal values of pulse shape factors for Gaussian derivatives in order to meet the requirements of FCC emission mask. Then we study the pulses obtained by Modified linear combinations and Least Square Error Combination of Gaussian derivatives for same, different and optimal values of the pulse shape factors. In the end we conclude the work based on the obtained results.","PeriodicalId":229600,"journal":{"name":"2014 Recent Advances in Engineering and Computational Sciences (RAECS)","volume":"522 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116572590","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 new kind of Ad hoc network with an immense improvement in technological innovations is emerging these days known as VANET (Vehicular ad hoc network). It is an assortment of vehicular nodes that act as mobile hosts establish a transient network without the assistance of any centralized administration or any established infrastructure. Therefore, it is called autonomous & self configured network. In VANET, two kinds of communication can be done to provide a list of applications like emergency vehicle warning, safety etc. These are between various vehicles known as vehicle to vehicle and between vehicles and roadside units known as vehicle to roadside communication. Performance of such kind of communication between vehicles depends on various routing protocols. We have a tendency to survey a number of the recent analysis leads to routing space.

In modern competitive market, low cost and high performance are the key factors to attract the customers towards their products. Growing system complexity demands robust control to mitigate system control and disturbances. As more and more components are integrated on to a single chip, the probability of damage is increased, as the different components have different characteristics and different operating conditions. So a condition monitoring techniques are employed which embraces a knowledge of failure mechanism of individual part or integrated system, and diagnosis the health condition of a system in real time such that if it drifts from scheduled outcomes, an appropriate action to be taken before serious deterioration or breakdown occurs. The electronic system needs a fault prediction methodology to prevent the system from accidental failure and discrepancies. In this paper, different failure prediction methods have been discussed. For an efficient working of system, it is the prime requirement to analyze reliability prediction of electronic components along with life cycle costs.","PeriodicalId":229600,"journal":{"name":"2014 Recent Advances in Engineering and Computational Sciences (RAECS)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114477124","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}

These methods should help us address issues such as ownership management, authentication, and forgery detection. This paper aims to propose an algorithm for secure photography by embedding photographer's face (or related features) as an invisible watermark into the images captured by a smartphone equipped with dual cameras. The proposed system embeds an image taken by front camera while photographing a scene from the back camera. The proposed algorithms are first profiled in Matlab to make them ready for implementation on the Android phone. The trade-off between data size, quality of the owner's image, and the quality of the scene images is used to design an optimal operating point for the system. The results shown in this paper show that the proposed method holds promising grounds for addressing the issues related to ownership management of mobile images.","PeriodicalId":229600,"journal":{"name":"2014 Recent Advances in Engineering and Computational Sciences (RAECS)","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122041448","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 reference current signals are generated by sensing the source voltage, load current and dc bus voltage. With these signals the driving signals are generated via hysteresis band PWM current controller. To check robustness of the control algorithm four different cases such as ideal, unbalanced, balanced distorted and unbalanced distorted main voltage are considered and simulated with different firing angle of the load.
