Authors: Zhu Xiongfeng, Hou Zhongxi, Liu Yang, Shang Guoqiang

IJAET/ Volume VII/ Issue IV/ Oct.-Dec..'2016/01-06

ABSTRACT
The conceptual design of the solar-powered airplane plane with considerable payload mass and payload power is studied for the present paper. Two parameters of the payload mass coefficient and the payload power coefficient are introduced to describe the payload. The couple parameters are substituted into the conceptual design derivation to yield the maximum flight altitude, wing loading, payload mass and payload power. A numerical test of the SolarEagle with the assumed Zephyr 7 parameters is brought forward. The result shows the feasible design of the SolarEagle using the above technical parameters is flying on 17km altitude with 310kg payload and 5kW payload power or flying on 17km altitude with 450kg payload and 2.6kW payload power.

POROUS RADIANT BURNER FOR HOUSEHOLD COOKING PURPOSE: A REVIEW

Authors: Vijay Kumar, Amandeep, Keshwer Eqbal Khan

IJAET/ Volume VII/ Issue IV/ Oct.-Dec..'2016/07-12

ABSTRACT
For cooking, liquefied petroleum gas (LPG) is one of the most commonly used fuels in India and many other countries. LPG being a clean fuel burns with no soot and has high calorific value than kerosene and wood. In India, as the living standard of the people is improving the number of LPG consumers is also increasing. The total domestic consumption of LPG in India is almost comparable with other petroleum products used in industrial applications. The thermal efficiency of the current LPG cooking stoves available in the Indian market are in the range of (60-65) % and at the same time the CO and NOX emissions levels are above the world health organization standards. Considering the energy conservation, environment issues and increase in demand of LPG in the near future. The present review paper summarizes the recent modification in the design of free flame conventional LPG burner by using porous materials and highlights its potential.

COMPARATIVE ANALYSIS OF THERMAL ACCUMULATION AT VARIOUS POINTSINSIDE A CAR CABIN

Authors: Amit Mehta, Sahib Singh*

IJAET/ Volume VII/ Issue IV/ Oct.-Dec..'2016/13-15

ABSTRACT
Car cabin heat is the major problem in many countries especially in India. Car owners are facing problems where the temperature is extremely high in the car cabin when they are parked directly under the sun during the summer season. The accumulated heat inside the vehicle cabin is affecting many interiors such as the vinyl materials of the dashboard, the leather covers and the electron IC- components. Also, it represents an uncomfortable operating period for the passengers. The temperatures inside the car can go as high as 60°C and surface temperatures up to 80°C during summer making the persons inside the car uncomfortable, Moreover, the car interior (seat cover, dash board etc.) can also have aging problem and bring damage to other goods present in the car. Therefore cooling of car cabin will result in increasing the durability of interiors of the car; will bring comfort to the persons inside the car and results in minimizing the Air conditioning load.In the present study, experimental and numerical analyses were conducted. The experimental results were obtained from measurements on a car parked unshaded area. Four different cases had been investigated consisting of full windows closing case,windows opening settings by 1cm, windows opening settings by 2cm and sun shade usage case. The temperature at 8 different locations inside the car had been recorded initially and 4 maximum temperature areas in the car have been identified and analyzed. Natural circulation take place with large scale cavity due to natural heat transfer from the dashboard and the rear windshield. The drop down of the front side windows by 20mm caused reduction in the front air gap by 18%. The sunshade on the front had considerably reduced the heat accumulation inside the cabin, where the dashboard surface temperature dropped by 23% and the maximum air temperature was found to be 25% lower.

INFLUENCE OF CUTTING FORCES IN DRILLING OF 34CrMO4

Authors: Sahib Singh*, KaranVohra,Vishal Gupta

IJAET/ Volume VII/ Issue IV/ Oct.-Dec..'2016/16-17

ABSTRACT
Drilling is an extensively used metal working operation through which holes are produced by means of multipoint cutting tool known as drill. Drilling is a roughing operation as the holes produced by this process are not perfect. During drilling process heat is produced which develops high temperature resulting in tool wear, dimensional inaccuracy and less surface finish. To increase tool life and to improve surface finish of the work piece during drilling we have to minimize the thrust force and torque on drill. This paper deals with the investigation of thrust force, torque on drill. The purpose of this paper is to find those values of spindle speed, feed and depth of cut during drilling where thrust force, torque on drill, current consumed and time taken will be minimum for 34CrMo4.

A LOW CONTRAST COLOR IMAGE ENHANCEMENT BASED ON COLOR SPACE CONVERSION 2D-DWT AND SVD

Authors: G. Saravanan* and G. Yamuna

IJAET/ Volume VII/ Issue IV/ Oct.-Dec..'2016/18-22

ABSTRACT
Digital Imaging systems are traditionally not good in low light conditions. In order to solve this issue, a new algorithm is proposed for contrast perfection. This technique first convert RGB color image to HSV, then the luminance part V decomposes into the four frequency sub- bands by using 2D-DWT. These techniques also apply the general histogram equalization (GHE) for V component then apply 2D-DWT it decomposes into four sub bands. To compute brightness improved LL sub band, normalize singular value matrix (SVD) obtained by both LL sub bands. The new LL sub band merged with high frequency sub bands, it reconstructs the image by applying 2D-IDWT. The new enhanced V combined with adaptive histogram equalized saturation part of S and H is unaltered due to color distortion and back to enhanced high contrast color image. The experimental results indicated that the image contrast improved by the proposed scheme is higher than the other methods and state-of-the-art techniques. .

REPLACEMENT OF THE BRICK BY PET BOTTLE WITH M-SAND
(New Innovative Constrcution Material)


Authors: Ravikumar S

IJAET/ Volume VII/ Issue IV/ Oct.-Dec..'2016/23-25

ABSTRACT
This Clay bricks are most commonly used in all kind of buildings such as for the load & non load bearing walls and columns. This bricks withstands high volume and increase the weight of the building. These are most commonly used to construct the walls and columns and in RC structure as non-load bearing walls.
This project is mainly based on replacement of PET (Polyethylene terephthalate) bottles filled with M-sand (Manufactured Sand) instead of bricks. The empty bottle alone cannot withstand the load, so it is filled with M-sand and Natural sand (N-sand) It is also known as pet bottle bricks. The strength obtained is greater than the bricks. It reduces the carbon emissions during burning of clay brick during the manufacture of brick. It is eco-friendly and energy efficient. The cost comparison also done between normal clay brick work with PET bottle brick work for cement mortar ratio of 1:3 masonry.
