Abstract

En 353 steel is an easily available and cheap material that is acceptable for heavy duty applications. Heat treatment on En 353 steel is improved the ductility, toughness, strength, hardness and relive internal stress in the material. X-ray diffraction (XRD) method is used to analyze the composition and the phase of the alloy material. The experimental results of hardness and microstructure are done to get idea about heat treated En 353 steel. It is found that the hardness of the En 353 steel is improved after the heat treatment and the microstructure is changed from ferrite to martensite.

Key words:En 353 steel, Heat treatment, Hardness, Microstructure.

Abstract
Neuro fuzzy hybrid system is a learning mechanism that utilizes the training and learning neural networks to find parameters of a fuzzy system based on the symptoms created by the mathematical model. Adaptive learning is the important characteristics of neural networks. Adaptive Neuro Fuzzy Inference System (ANFIS) is used for system identification based on the available data. The main aim of this work is to determine appropriate neural network architecture for training the ANFIS structure inorder to adjust the parameters of learning method from a given set of input and output data. The training algorithms used in this work are Back Propagation, gradient descent learning algorithm and Runge-Kutta Learning Algorithm (RKLM). The experiments are carried out by combining the training algorithms with ANFIS and the training error results are measured for each combination. The results showed that ANFIS combined with RKLM method provides better training error results than other two methods.

Abstract

Noise pollution has become a common problem in bigcities. Most of the noisegenerated the sounds of transportation and everything in the air. All of these noises on the highways impact to the increasing intensity of noise pollution. The research objective was to estimate the noise reduction using vegetation as a noise barrier in the highway along Waru - Sidoarjo. The present study was conducted on the highway alongWaru - Sidoarjo with existing vegetation at the side of the highway. A series of SLM(Sound Level Meter) was arranged at various distances from the highway, in the presence of vegetation, while another series was arranged in the absence of vegetation over the vegetation, the other series as control of those was placed without vegetation. Vegetation types used as samples wereSamaneasaman,Pterocarpusindicus,Tectonagrandis and Pithecellobiumdulce.From the measurement, noise reduction could be made created equal for each of the vegetation, so that estimation of noise reduction could be generated for specific distances. Theresult showed thatPithecolelobiumdulce havethe highest noise reductioneffectivity(P < 0.01) of 10.12% at 20 m distance.Noise was reduced when the location of the listener was away from the noise source and the noise reduction equation for this vegetation was y = 2.67 ln (x) + 2.18 with coefficient determination (R2) = 0.92.It was suggested that the settlement should be built more than 20 m away from the highway.

Abstract
This work explains recent advances in II–VI Ternary Semiconductor Alloys. Current work has significant potential for low-cost, scalable solar cells. The close interplay among the properties of the materials and their utility in solar cells is also briefly discussed. Almost group II–VI materials are direct band gap semiconductors with high optical absorption and emission coefficients. Group II–VI materials are good candidates for use in solar cells. The Electrical and Optical Properties of II-VI Ternary Semiconductor Alloys from Binary Semiconductor Alloys are derived using Additivity rule with Quadratic expressions. The Electrical and Optical Properties studied in this group are confined to Refractive index, Optical Polarizability, Absorption coefficient and Energy gap. A comparison of these data is made with reported data available. The relative merit of Present method based on refractive indices without recourse to the experimental methods is stressed. Merits of study of this group alloys is also outlined.

Abstract
In the present study, the effect of injection timing on combustion and heat release characteristics were analyzed in a single cylinder direct injection compression ignition engine using Neem, Rice bran and Pongamia biodiesels. The biodiesel of Neem, Rice bran and Pongamia was prepared by transesterification process using 2.5 gms of Sodium hydroxide and 400 ml of methanol between 70oC and 100oC. All the three biodiesel were blended in 5%, 10% and 15% ratios. The results showed that at 6 CAD advancement of injection timing, the maximum rise in combustion pressure was 2% to 4% and the rate of heat release was also improved with higher blends of Pongamia biodiesel. Blends of Neem and Rice bran also showed positive improvement but lower that Pongamia.
