Single cylinder four stroke CI engine Exhaust Manifold System back pressure reduction: A review
The present review paper is on the performance improvement of IC engine by using backpressure reduction in the exhaust manifold and their CFD analysis of Single Cylinder Four Stroke C.I. Engine. It is found that development of energy-efficient exhaust manifold system is possible by minimization of backpressure on the engine, due to an increase in brake thermal efficiency. Effective utilization of energy from exhaust manifold can be achieved by designing for backpressure reduction by energy-efficient exhaust manifold system. The exhaust manifold system design with reduced back pressure requirements is an important factor for upgrading engine performance. It is analysis by CFD on reduction in the backpressure of the exhaust manifold system to increase the efficiency.

ABO blood group and Rh factor distribution in population of Bhopal, Madhya Pradesh
Blood group system was disclosed by Karl Landsteiner, the ABO blood group system is the most vital blood group system in Transfusion Medicine. The blood group systems are also relevant in population genetic studies, researching population migration patterns as well as in solving certain medico-legal issues. This study will be carried out with an objective to provide data regarding gene frequency and distribution of ABO and RH blood groups in the population of Bhopal, Madhya Pradesh, India. Blood samples will be collected from willing individuals of Bhopal (M.P.) 180 blood samples are required for this study. Before blood sample collection we take written consent of subjects and short questionnaire based on such as an address, age, any type of diseases, medical history and sex. After blood sample collection the samples will analyze for blood group ABO and Rh factor by slide agglutination method by using Anti-A, Anti- B, Anti-D per ABO blood grouping.

Efficient battery charging technique using a soft-switching DC-DC Converter
Soft-switching schemes have become famous nowadays because of its simplicity and ease of control. This paper presents an efficient way of battery charging by using a parallel- loaded resonant converter. This converter is constructed by cascading a half-bridge inverter, L-C-L resonant circuit, and a full bridge rectifier. The operation of circuit charger is switched with the technique of zero-voltage switching and resonant components. The main advantages of this converter are low EMI, low switching losses, less weight of components due to high frequency and high efficiency. The conversion efficiency of the proposed converter reaches up to 88%. Two types of charging algorithms such constant current (cc) charging, constant current–constant voltage (cc-cv) charging were implemented using proposed converter topology in MATLAB/ SIMULINK environment and the results obtained are satisfactory.

Image quality assessment to enhance handwritten signature
The fact that the signature is widely used as a means of personal verification emphasizes the need for an automatic verification system. Verification can be performed either Offline or Online based on the application. Online systems use dynamic information of a signature captured at the time the signature is made. Offline systems work on the scanned signature. We have worked on the Offline Verification of signatures using a set of shape-based geometric features. The features that are used are Baseline Slant Angle, Aspect Ratio, Normalized Area, Center of Gravity, number of edge points, number of cross points, and the Slope of the line joining the Centers of Gravity of two halves of a signature image. Before extracting the features, preprocessing of a scanned image is necessary to isolate the signature part and to remove any spurious noise present. The system is initially trained using a database of signatures obtained from those individuals whose signatures have to be authenticated by the system. For each subject, a mean signature is obtained integrating the above features derived from a set of his/her genuine sample signatures. This mean signature act as the template for verification against a claimed test signature. Euclidian distance in the feature space between the two. If this distance is less than a pre-defined threshold(corresponding to a minimum acceptable degree of similarity), the signature is verified to be that of the claimed subject else detected as a forgery. The details of preprocessing as well as the features depicted above are described in the report along with the implementation details and simulation results.

Performance analysis of batteries fast charging process topology
The scarcity of fossil fuel and increasing pollution leads the use of Electrical Vehicles (EV) and hybrid electrical vehicle instead of conventional Internal Combustion (IC) engine vehicle. The scope of this paper is to design and develop an electrical vehicle fast charge controller using Battery Management System (BMS) with Cuk Converter that is powered by an electric motor which gets its supply from rechargeable batteries. This paper will focus on, main battery (lithium ion) and auxiliary battery (lead acid) parts of battery storage, aimed to fast charging of electrical vehicle. An electrical vehicle requires an on board charger (OBC) to charge the main as well as auxiliary battery. The objective of this paper is to design a charger to charge both the battery fast and to reduce the charging stress on main battery by employing an auxiliary battery in Battery Management System. Due to such BMS to enhance battery lifetime, to avoid prolonged charging and to reduce overall cost of battery management system. These proposed topological are simulated in MATLAB software and some results are show the performance of the system.
