Using Design of Experiments Approach to analysis Factors Effecting on the PV Cells

Many factors affect the performance of a PV module. In this experiment, we will use the factorial experimental design method to investigate these factors. Several factors are studied in this experiment such as phase change martial type, PCM thickness, fin length thickness, fin count and the wind speed. A factorial design is often used by scientists wishing to understand the effect of two or more independent variables upon a single dependent variable so applying factorial design in PV parameters will give us the most significant parameter on the temperature of the cells. The statistical results showed that the most significant factors affected on the temperature of the cells are PCM thickness and wind speed.

Improvement in Productivity by Lean Approach Method in Amararaja Industries

To survive in the market, the goal of any manufacturing industry is to produce goods at the lowest time and lowest cost possible. To attain this lean approach improves productivity systems by manufacturing without wastes. The purpose of this project work is to improve production system in assembly section and finishing section at the Amara raja batteries, Tirupathi. In the finishing section the cycle time is reduced from 103 sec to 68 sec and production rates is increased from 245 skids shift to 371 skids shift. The fatigue of workers also reduced by adapting belt conveyor system.

Expermential Investagation and Analysis of Bitumen Modifaction Using Fly Ash

The increase of crude oil prices in recent years resulted in an increase in bitumen prices as crude oil is origin for bitumen, asphalt and in other hand the fly ash from the power generating plants causes severe disposal problems. The main purpose of this project is to study the possibility of using fly ash as mineral filler in Bituminous paving mixes. Fly ash, a coal combustion product once treated as waste and disposed in landfills, is used today in substructure and road works. The research of fly ash properties may solve the problems of treatment and intelligent use of this residual material. This Marshall stability test is employed to determine the properties like stability, flow value, air voids, voids in mineral aggregate VMA , voids filled with bitumen VFB for a Dense Bituminous Macadam DBM mix. The experimental work is carried out by using specifications from MORTH Ministry of road transports and highways, specifications for road and bridge works,5th revision .By replacing the stone dust with fly ash at the levels 4 , 6 and 18 the results are compared. The variation of properties, optimum bitumen and fly ash contents are evaluated. It is observed that the mixes with fly ash as filler not differ much in properties when compared with control mix and satisfy desired criteria specified by a much higher margin. Hence, it has been recommended to utilize fly ash wherever available, not only reducing the cost of execution, but also partly solve the fly ash utilization and disposal problems.

A Review on Fire Impacts on Concrete Structures

Concrete has been used as a construction material due to its versatile behaviour. It exhibits a high degree of fire resistance. The characteristic ability of concrete structures to combat one of the most devastating catastrophes can be attributed to its constituent materials which make it passive and have relatively poor thermal conductivity. However, concrete structures must be designed for fire outbreaks. The properties of concrete must be balanced against concerns about its fire resistance and susceptibility to spalling at elevated temperatures. In this paper, the causes, effects and some remedies of deterioration in concrete due to fire hazard will be presented. Also, some economical solutions to produce fire resistant concrete will be discussed.

Burnout Syndrome, Shift Work Disorder, Work Rumination and Quality of Work Life among Nursing A Valuable Staff

Nursing is a profession within health care sector, focused on the care of individuals, families, and communities so that they may attain, maintain, or recover optimal health and quality of life. Nurses play a pivotal role in the health care system. Today, nursing profession is facing numerous challenges, leading to poor quality of nursing care delivery to patients. In an attempt to look into this problem, this study considers the following concepts

New Design Criteria in Performance Based Earthquake Engineering

In order to increase the resistance of the building against earthquake effect in performance based design, the main objective is to select a performance target as design criteria and to design the structure to meet this target. In the nonlinear analysis with finite element method, the formation of the plastic hinge can lead to great potential damage to the building, so they are one of the basic data to determine the state of the building. Accordingly, if the number of plastic hinges in the building is increased, the total horizontal load carrying capacity of the structure increases proportionally. Theoretically, when the structure of plane frame bearing system reaches a plus value of the degree of indeterminacy of the structure, the structure will reach the capacity to bear the largest final horizontal load. For this reason, in this study, in addition to the current design criteria in the relevant codes, it is aimed to increase the structure to the maximum load carrying capacity level by adding the new criterion “to increase the number of plastic hinges to be formed in the structure as much as possible and to keep the structure below its targeted performance by code”. As a result of the studies conducted according to the new performance criteria presented, the load bearing capacity of the frame bearing system has increased by 50 compared to the current code results.

Microcontroller Based High Voltage Low Voltage Protection System

This paper presents methods for estimation and autonomous control of voltage which is done by an unmanned microcontroller based protection system with thermistor. It used to check temperature along with voltage protection. The transformer used is copper cored and it works only on alternating current source. The thermistor is used to detect the temperature in case of overheating or fire problems.GPS module is also used to aware the owner of the system by sending the text message on phone in case of detection of any unusual activity. Such as low voltage, high voltage, high temperature. The main challenge is to make a sequence of codes for proper functioning.
