1 Different Materials Effects on Bloodstain Pattern Analysis for Crime Scene Reconstruction
Prof.(dr.) Samir Kumar Bandyopadhyay, Nabanita Basu

Abstract-The Oxford Dictionary defines ‘Crime’ as ‘an action or omission which constitutes an offence and is punishable by law’. The Uniform Crime Reporting program conducted by the Federal Bureau of Investigation (FBI) divides offences particularly into 3 broad categories based on the seriousness of the crime. They are – Part I offences, Part II offences and Other Offences. Part I offences as the FBI records are serious crimes that occur with regularity in all areas of the country and are likely to be reported to the police. Part I offenses include Criminal homicide, forcible rape, aggravated assault, burglary (breaking or entering), Larceny-theft (except motor vehicle theft), motor vehicle theft, arson. Part II offences include, other assaults (simple), Forgery and Counterfeiting, Fraud, Embezzlement, Stolen property: buying, receiving, possessing, Vandalism, Weapons: carrying, possessing etc., Prostitution and Commercialized vice, Sex offenses (except forcible rape, prostitution, and commercialized vice), Drug abuse violations, Gambling, Offenses against the family and children, Driving under the influence of an intoxicant, Liquor laws, Drunkenness, Disorderly conduct, Vagrancy. Other offenses include Suspicion, Violations by juveniles (under the age of 18) of local curfew or loitering ordinances, runaways by juveniles (under the age of 18) taken into protective custody under the provisions of local statutes. Given the large scale uncertainty involved in the study and interpretation of bloodstain patterns, we intend to design a semi-supervised tool that could probabilistically make a prediction of the relative position of the perpetrator/s, victim/s and bystander/s (if any) using bloodstain pattern evidence in conjunction with other circumstantial evidence such as presence/absence of objects in a crime scene, wound analysis results etc. This in its turn would particularly aid the whole process of crime scene reconstruction within a juridical setting.

2 Remit of Lower Order Harmonics with LMS Filter in Grid Connected Single Phase PV Inverter
Vijaykumar Kuchipudi, N Sriharish, Ch Rambabu

Abstract:-In this paper, explains the use of Cuk converter with MPPT technique in a photovoltaic system. When an adaptive filter operates in a changeable environment the filter coefficients can adapt in response to changes in the applied input signals and near the optimum solution. Its inner current control is realized with a dead-beat controller that allows fast tracking of stochastically fluctuating load currents. The approach is based on the measurement of line currents and performs the compensation of selected harmonics using a closed-loop repetitive-based control scheme based on a finite-impulse response digital filter. It is characterised by utilizing power balance at dc link in the steady state conditions, and hence eliminating the array output power detection. The output current of the inverter can be adjusted according to the voltage of the photovoltaic (PV) array so as to extract the maximum power from it. The power electronics inverter is a major contributor to the cost of the PV generation system. Price reduction is therefore an important issue in solar technology development. The proposed system should be implemented in MATLAB/SIMULINK.

3 Energy-Efficient Routing for Reliable Communication in Ad Hoc Networks
M.Savitha, N.Jayapal,M.Kanimozhi

Abstract:-Wireless Sensor Network is a network of sensor nodes without having any central controller. Its growth is expeditiously increasing and that’s why there is an immense field for research in this area. Sensors depend entirely on the trust of their battery of power, which can’t be revitalized or substituted. So the design of energy aware protocol is essential in respect to enhance the lifetime network. LEACH is an energy efficient hierarchical based protocol that balances the energy expenses, saves the node energy and hence to prolongs the lifetime of the network. So this paper presents a detailed review and analysis of LEACH protocol. Comparison of the various networks parameters is done in the form of tables and graphs. The simulation of the work has been carried out by using own set of parameters and in the last of the paper conclusions is drawn.

4 Safety for first responders using automatic and Robust multiuser breadcrumb system
Suvedha.K, Anand Joseph Daniel.D, Karthick.P, Rajini Girinath.D

Abstract:-In disaster situations the radio communication problems faced by First Responders is a highly needed tool for increasing safety in emergency response and military urban operations. Coordination and communication support are of the utmost importance in an indoor firefighter mission. Our work is focused on the frontline interaction between teams of firefighters and the base station in contrast to some large scale emergency response research. The drawbacks in firefighter communication systems have been investigated. To support firefighters inside buildings Breadcrumb systems (BCS) have been proposed by transmitting their physiological parameters to base stations outside the buildings. This project describes the design, characteristics and implementation of an automatic and robust multiuser breadcrumb system for firefighter applications. A new reliability model that consists of an optimized redundancy degree for breadcrumbs, a decision support system for wireless link estimation, a height effect solver to handle the gap in link quality after breadcrumbs drop from the dispenser, and an adaptive transmission power control to handle link quality variation problems in harsh environments have been proposed.

5 Regeneration of historical document Images based on the method of Binarization
V.Arivumalar, Suganya, K.Rejini, SM. Maheshwari, D. Rajinigirinath

Abstract:-Due to the large inter/intra variation, segmentation of foreground from background becomes a very challenging task. Analysis of visual image sharpness and detection of blur image by using the Human visual system. Because of additive noise, an imaging system capture the image emulates the degraded version of an original image. Binarization affects the process of recognition stage by stage and analysis of pixel-based binarization approach is identified for archaic handwritten document images. And the identification of missed text, text strokes, false alarms, background noise, character enlargement. The mean shift and trimmed median filter are used in the post processing step for phase deriving features. Adaptive median filter is used in existing system, which is removing the needed portions of image and also improving the performance. Removal of form line and stages of binarization is included in the preprocessing step. Binarization approach is improved based on high recall performance.
