Thermoelectric devices are solid-state devices. Semi-conductor thermoelectric power generation, based on the Seebeck effect, and semi-conductor thermoelectric cooling, based on the Peltier effect, have interesting capabilities compared to conventional power generation and cooling systems. The absence of moving components results in increase in reliability, a reduction in maintenance, and an increase of system life; the modularity allows for application in wide range without significant losses in performance; the absence of working fluid avoids environmental dangerous leakages; and the noise reduction appears also to be an important feature. With the rapid development of techniques to make excellent semi-conductor materials the practical applications and theoretical investigations of the thermoelectric devices have come into focus. This article begins with a brief overview of thermoelectric technology, thermoelectric materials, thermoelectric module construction and operation. A review of recent developments in research, commercial development, and typical applications of thermoelectric devices is made. The article draws conclusions on the development and potential application of thermoelectric devices suitable for thermoelectric cooling. © Taylor & Francis Group, LLC.

In this experimental study, an attempt has been made to optimize the process parameters of friction stir welding (FSW) for tensile strength and percentage elongation using Taguchi-based gray relation analysis (GRA). An orthogonal array of L9 has been implemented to fabrication of joints. The experiments have conducted according to the combination of rotational speed, tool tilt (TLT) and types of tool pin profile (TPP). The results revealed that the rotational speed is most significant process parameter with percentage contribution of 96.24 %. On optimization, tool rotation speed of 1,550 rpm, TLT angle of 4° and octagonal-type TPP have been found to be the best parameter setting for FSW process of aluminum 6061 and 6082 alloy welds. To ensure the robustness of GRA, a confirmation test was performed at selected optimal process parameter setting. © 2014, The Brazilian Society of Mechanical Sciences and Engineering.

Microwave welding process is almost in the league of joining the composite materials. But, it is really challenging to align with metals because they reflect the microwaves. In this paper, mild steel and stainless steel have been joined by the microwave welding at 2.45 GHz and 900 W. The joint has been formed at 600 sec exposure time. Ni-based powder is used to join the metals. The characterizations of joint have been carried out through microstructural analysis, tensile strength, elongation, and microhardness. The results reveal that the joint formation is clearly visible in microstructure. Tensile strength, elongation, and microhardness are 340.16 MPa, 11.67%, and 130 Hv, respectively. © 2013 Taylor & Francis Group, LLC.

The friction stir welding is a pioneering solid-state metal joining technique for producing high-quality joints in materials. In this article, Taguchi approach is applied to analyze the optimal process parameters for optimum tensile strength and hardness of welded dissimilar A6061 and A6082 alloys. An orthogonal array of L9 is implemented and the analysis of variance is employed to investigate the importance of parameters on responses. The experimental tests, conducted according to combination of rotational speed, tool tilt and types of tool pin profile parameters. The results indicate that the rotational speed is most significant process parameter that has the highest influence on tensile strength and hardness, followed by tool pin profile and tool tilt. The optimum results verified by conducting confirmation experiments. The predicted optimal value of tensile strength and hardness of dissimilar joints produced by friction stir welding are 267.74 MPa and 80.55 HRB, respectively. © IMechE 2012.

In this paper we are studying the performance of Hopfield neural network for recalling of memorized patterns from the Hebbian rule and genetic algorithm for English characters. In this process the genetic algorithm is employed in random form and sub-optimal form for recalling of memorized patterns corresponding to the presented noisy prototype input patterns. The objective of this study is to determine the optimal weight matrix for correct recalling corresponding to noisy form of the English characters. In this study the performance of neural network is evaluated in terms of the rate of success for recalling of noisy input patterns of the English characters with GA in two aspects. The first aspect reflects the random nature of the GA and the second one exhibits the suboptimal nature of the GA for its exploration. The simulated results demonstrate the better performance of network for recalling of the stored letters of English alphabets using genetic algorithm on the suboptimal weight matrix. © 2012 Elsevier B.V.

There are two important requirements in design and development of novel drug delivery system(NDDS).First it should deliver the drug at pre-determined rate and second therapeutic effective amount of drug should reach the site of action. The conventional dosage forms like tablets, capsules are unable to meet this requirement. Noisome are nonionic surfactants vesicles formed due to self-assembly of hydrates surfactant monomers. The proposed review deals with the composition, methods of preparation, stability, therapeutic potential. Mainaim for development of noisome is for sustain release of the drug and for drug targeting to specific sites of the body. © 2014, International Journal Of Pharmacy&Technology.

In the present investigation, A356/C355 aluminium alloys are welded by friction stir welding by controlling various welding parameters. A356 and C355 aluminium alloys materials have a set of mechanical and physical properties that are ideally suited for application in aerospace and automobile industries and not widely used because of its poor weldebility. To overcome this barrier, weldebility analysis of A356 and C355 aluminium alloys with high speed steel (Wc-Co) tool has been investgated. An attempt has been made to investigate the influence of the rotational speed of the tools, the axial force and welding speed on tensile strength of A356/C355 aluminium alloys joint. The experiments were conducted on a milling machine. The main focus of investigation is to determine good tensile strength. Response surface methodology (box Behnken design) is chosen to design the optimum welding parameters leading to maximum tensile strength. The result shows that axial force increases, tensile strength decreases. Whereas tool rotational speed and welding speed increase, tensile strength increases. Optimum values of axial force (3 /KN), tool rotational speed (900 RPM) and welding speed (75 mm/min.) during welding of A356/C355 aluminium alloys joint to maximize the tensile strength (Predicted 223.2 MPa) have been find out. © 2014 The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg.

In this study effective Young's Modulus of Ni-Alumina composites were evaluated using object-oriented finite element method (OOFEM). Two different type of composites having particulates structure and interpenetrating phase structure were studied. Three samples of each type of composites having 40%, 60% and 80% Ni reinforced in Alumina were studied. The results obtained from OOFEM were compared with ultrasonic measurements reported in literature. For certain particle-reinforced composites, the elastic moduli measured ultrasonically did not obey the OOFEM. The mismatch was attributed to the presence of damage because of debonding between Ni and Alumina phases. This damage could be accounted for using OOFEM. Composites with damage were treated as porous material and modeled as three phase composites containing nickel, alumina and damaged phase. To match the Young's Modulus with the ultrasonic measurements, the percentage of damage pixels in composites were obtained. Local stress distribution was studied across the mesh of composites to understand the effect of porous microstructures. © 2013 Elsevier B.V. All rights reserved.
