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.

Parametric study of castellated beam with coupled stiffener
The castellated beam is artificial from its parent solid I beam by cutting it in zigzag pattern and again amalgamation it by welding, so that the depth of the beam increases. Therefore, due to increase in depth of beam load carrying capacity of the parent I section is greater than before with same quantity of material. The increase in depth of castellated beam leads to web post buckling and lateral torsional buckling breakdown when these beams are subjected to loading. Generally the opening provided for castellated beams are hexagonal shaped openings, which are dispersed at regular intervals on the web portion of castellated beam. Castellated beams are comprehensively used as flexural members in steel construction. The inexpensive and structural advantages of these rudiments have prompted many researchers to investigate the failure performance of such structures. In this paper steel I section ISMB 150 is selected, castellated beams are fabricated with increase in thickness of stiffener and stiffener is provided between the two openings and beam is analyzed with the help of Finite Element Analysis (ABAQUS) software. Experimental testing is conceded out on beam with two points loading. The deflection at centre of beam and various failure patterns are studied. The prevalent use of castellated steel beam as a structural constituent has prompted several exploration in their structural behavior. The aim of this manuscript to find out increase or decrease the load carrying capacity of optimized stiffener is provided within the hexagonal opening of castellated beam. Study shows that use of stiffeners in the web portion of beam helps in minimizing these failures.

Parametric study of CFST column element with and without shear studs under axial compression
The compressive performance of the concrete-filled steel tubular (CFST) members is investigated in this study. Tests are carried out on the specimens under axial compression and bending. The parameter of the experimental work is the steel relative amount of the cross section, and the hollow tubular members are designed for comparison. In recent times, engineers have increasingly utilized composite members of concrete-filled steel tubes (CFSTs) in contemporary projects such as buildings and bridges. Concrete Filled Steel Structures (CFST) offers wide benefits like high strength, ductility, energy absorption with the combined benefits of steels and concrete. It also reduces the time consumption in constructing since it doesn’t require shuttering works hence they are frequently used. Moreover, the CFST members are more economical and allow for rapid construction and cost savings by eliminating formwork and workmanship. Concrete filled steel tube is gaining supplementary popularity now days in construction area. Concrete filled steel tube is component with good performance resulting from the confinement effect of steel with concrete and design versatility need. This Paper present a review the performance of CFST comparing the models with & without shear studs differentiating position of shear studs. The composite actions of steel and concrete to occur there need a strong bond between steel and concrete interface. In the present study, it mainly focuses on design load carrying capacity of CFST using Euro code and Indian code &compares it with the analytical & experimental result. Analysis of CFST column using the Finite element method (ABAQUS) software and the experimental study is done on the selected case under concentric loading condition.

Evaluation of properties of paver block using dismantaled concrete for medium traffic
Concrete paver blocks are versatile, attractive, cost-effective and functional, blocks for the construction of pavement, if paver blocks are correctly manufactured and laid then paver blocks, required very less maintenance. In India as per Indian standard paver blocks can be used for roadways. Paver blocks are divided into different traffic categories by Indian standard i.e. very heavy traffic, non-traffic, Light-traffic, medium traffic, and heavy traffic. Wastes of the demolished building are generally used in landfills, these waste contain waste of bricks and concrete. These demolished building wastes which are also known as Demolish Concrete Aggregates are increasing gradually; Many engineers are working on these wastes to make it effectively useable. One of the best uses of this waste is to use it as a coarse aggregate in concrete. In this project coarse aggregate is replaced by Demolish Concrete Aggregate which contains wastes of concrete from demolished i.e. wastes from a beam, column, and slab up to 100% at an interval of 10% in M 40 concrete of paver blocks for medium traffic. Demolish Concrete Aggregate which passes from 10mm IS sieve and retained on 4.75mm IS sieve was used. For this project test like compressive strength and the flexural test was performed on paver blocks and to evaluate the workability of fresh concrete slump cone test was performed. The study indicated that compressive strength, flexural strength, and workability of concrete is required but aggregate enough to be used as paver blocks for medium traffic.
