DESIGN AND FABRICATION OF SINGLE CYLINDER SOLENOID ENGINE

Abstract

Solenoids are the coils of wire when connected to electric current a magnetic field is set up at its surface surrounding and this works as electromagnet which applies an electromagnetic force over a metallic element. The electromagnetic force depends upon the current flowing through the coil & number of turns that is wound around the cylinder. Solenoids help convert electrical energy into mechanical work i.e. a linear motion for the application that requires quick activity. It is an electromagnetic device which operates the piston inside a cylinder as per the coil magnetism and creates no harm or pollution into the atmosphere compared to conventional IC engines which runs on burnt fuel consumption causing dangerous pollution to the natural environment. As the current passes through the coil, the electromagnetic field is induced and the engine runs on magnetic attraction and repulsive principle. In this thesis a single cylinder solenoid engine is designed and fabricated which runs on a 230v AC supply which gives out approximately 82% of efficiency.

ANALYSIS OF SAFETY MANAGEMENT IN COMMERCIAL BUILDING CONSTRUCTION

Abstract

The construction industry is the second last biggest industry in India. Construction of any structure includes various danger and critical situations. For implementation of successful construction project an effective safety management system is required. The object of the study is to cover existing safety issues in commercial projects. The study also focused on the factors effecting safety management during construction at site work. To achieve the goal of this study quantitative research approach will be conducted, in which the questionnaire survey can be used. The questionnaire include the mostly questions about safety issues during construction at site. The questionnaires will distribute to the construction workers. The interview method also applied to those workers who unable to understand and read the questions. In questionnaire Likert scale 1 to 5 will be used. Result of this study will be determined through relative importance index method and the rank will be determined. In this study the researcher trying to know about the most affecting factors of safety management. This study will be helpful to know about drawbacks in safety management and to improve the safety issues.

ANALYSIS OF WATER-RESISTANCE STRUCTURE AT COASTAL AREA WITH HSC

Abstract

Over the years studies have revealed that location and environmental impact are important factors to be considered in building materials selection. These have become major criteria in selection of appropriate building materials especially in the coastal regions of the world. Hence, in order to curb these effects, understanding the impact of this saline air on building materials and the way towards improving the resistance of buildings within this area to salt reaction is necessary. This study present the result gotten from the review of literature on the effect of salt on buildings in coastal areas and the possible ways of ensuring a reduction of the negative effect of this salt reaction with building materials. Findings revealed that salt attack on concrete and steel reinforcements leads to structural failure in buildings. Also, moisture penetration leads to blistering, chalking, and peeling of paints, which leads to constant re-painting of buildings. Cracking of walls, deterioration of floorboards and wood degradation a

AN EXPERIMENTAL STUDY ON MECHANICAL PROPERTIES OF LIGHTWEIGHT AGGREGATE CONCRETE WHEN FINE AGGREGATE IS REPLACED WITH CINDER POWDER AND DOLOMITE POWDER

Abstract

in recent years because of its many advantages over regular Concrete. Low density and high thermal conductivity are two of the main advantages of lightweight concrete. Its advantages include reduced dead weight, faster construction, and lower transportation and handling expenses. Instead of cinder from steel mills, coarse aggregate has been used. Cement has an uneven and porous surface because of mineral deposits. Due to the low specific gravity of cinder in compressive with natural particles, the cinder-based Concrete was lighter than conventional Concrete. According to the literature, the primary purpose of using cinder material is to reduce costs and the amount of garbage that must be disposed of while also aiding in reducing dead load. An experimentally study has been conducted on concrete with partial replacement of conventional fine aggregate by cinder powder. The M25 concrete mix is designed. We make concrete by replacing fine aggregate with cinder of different percentages like 0%, 20%, 40%, 60%, 80% and 100% and fine aggregate by dolomite powder in 10%, 20%, 30%, 40% and 50% with curing of 28 days.

SEISMIC EVALUATION OF EXISTING STRUCTURE

Abstract

Buildings are planned following code standards, satisfying all of the code\'s particular criteria and assuming that structural parts would behave in a linear elastic manner. Furthermore, it is vital to understand the behaviour of buildings built to earlier regulations or that were not meant to withstand earthquake pressures. Natural disasters are known to strike the world from time to time, posing a major hazard. The repercussions of earthquake reoccurrence, in particular, include the loss of human lives and the damage of property, both of which impact the natural economy. Because earthquakes cannot be foreseen or avoided, the ability of buildings to withstand seismic forces becomes more crucial. This thesis attempts to examine the performance of a typical chosen R.C. building regarding seismic vulnerability, keeping in mind the ongoing revision of the seismic zones in India and the lack of suitable design and detailing of buildings against earthquakes. For this seismic evaluation, a linear static has been performed by software ETABS considering material modification factor (Knowledge factor, K) FEMA 154. The analysis results showed the performance levels, the components\' behaviour, and the building\'s failure mechanism. It also showed the failure concerning the concrete deterioration of the existing buildings. Based on the analysis retrofitting is done by considering shear walls at different positions of the building, and the result has been compared with a term of story displacement, story drift, time periods, base shear and area of steel, and several columns failure with Knowledge factor.

DESIGN AND FPGA IMPLEMENTATION OF AN XOR BASED 16-BIT CARRY SELECT ADDER FOR AREA DELAY AND POWER MINIMIZATION

Abstract

Now a days in the world of VLSI Technology, the word low power consumption is only possible with the concept of Reversible logic design. Reversible concepts will attain more attraction of researchers in the past two decades, mainly due to low-power dissipation and high reliability. It has received great importance due to because of there is no loss of information, while we are processing the data from input to output. The study of designing fast circuits that use less power and take up less space is one of the most important aspects of VLSI design. To implement the CSLA in FPGA, the Verilog code of 4-bit CSLA, 8-bit CSLA and 16-bit CSLA have been written. These codes are then simulated in Model sim software to check the functionality of the design. When the simulation results are ok then the synthesis and power analysis is done in Quartus II software. Finally, The 4-bit CSLA and 8-bit CSLA in Altera DE2-115 FPGA board. Due to pin constraints up to 8-bit CSLA have been implemented.
