E-wastes consist of discard of electronic appliances such as computers, mobiles and telephones. Major producers of e-wastes are USA, China, Europe and Australia and the total estimate of these products is about 25 million tonnes per year. These countries are forced to adopt the "reuse" procedure to save environment and money flow. However certain e-wastes are having their self-life, which cannot be reuse. Hence, it is essential to recycle or disposal of these with suitable precautions. Uncontrolled disposal and recycling activities generate and release high toxic metals such as Hg, Pb, Cd, Cr, Cr(IV), Co, Cu, Ni, and Zn. These also release high concentrations of different types of flame retardants such as PolyBrominated Diphenyl Ethers (PBDEs), Poly-Chlorinated Biphenyls (PCBs) and OrganoChlorine Pesticides (OCPs). In this current research paper, potential environmental health consequences of these toxic metals and organo compounds are described.The selection of this topic is to evaluate electronic waste (e-waste) pollution and the toxicsubstances present in the e-waste and their threats to human health. Due to technologyadvancement and development makes new innovative electronic products which areaffordable rather repair outdated equipment. It is evident that disposal of electronicproducts is due to production of new ones. This article mainly focuses on overview ofIndia's current e-waste scenario and their problems in recycling and disposal of e-waste.The tools for e-waste management like life cycle assessment (LCA), material flowanalysis (MFA) have been developed to manage ewastes especially in developedcountries. By developing eco-design devices and collecting e-waste and safe handlingthe disposal brings clean environment. There is no exact tool to solve this issue.

This paper presents the simulation and the experimental validation of the designed robust power system stabilizer (RPSS) to stabilize a linearized uncertain power system using Glover-McFarlane's H∞ loop shaping design procedure. Guidance for setting the feedback configuration for loop shaping, weighing functions selection and synthesis are also presented. The efficiency of the designed controller is simulated using Matlab/Simulink and tested by implementing on real time environment using dSPACE work stations DS1005 and DS1104. The real time experimental results of RPSS are compared with that of the conventional power system stabilizer (CPSS) for a three phase fault. Also, the real time simulation results of RPSS are compared with the off-line simulation results of RPSS, thus validating the simulation results with the experimental results. Justification of robustness is also presented by considering three different operating points. The proposed method presented in this paper shows the effectiveness of the RPSS in damping the power system oscillations. © 2011 Elsevier Ltd. All rights reserved.

In this paper, the experiments of tensile and flexural tests were carried out on composites made by reinforcing jowar as a new natural fibre into polyester resin matrix. The samples were prepared up to a maximum volume fraction of approximately 0.40 from the fibres extracted by retting and manual process, and compared with established composites like sisal and bamboo developed under similar laboratory conditions. Jowar fibre has a tensile strength of 302MPa, modulus of 6.99GPa and an effective density of 922kg/m3. It was observed that the tensile strength of jowar fibre composite is almost equal to that of bamboo composite, 1.89 times to that of sisal composite and the tensile modulus is 11% and 45% greater than those of bamboo and sisal composites, respectively at 0.40 volume fraction of fibre. The flexural strength of jowar composite is 4%, 35% and the flexural modulus is 1.12 times, 2.16 times greater than those of bamboo and sisal composites, respectively. The results of this study indicate that using jowar fibres as reinforcement in polyester matrix could successfully develop a composite material in terms of high strength and rigidity for light weight applications compared to conventional sisal and bamboo composites. © 2011 Elsevier Ltd.

A linear stability analysis of convection in viscoelastic liquids with temperature-dependent viscosity is studied using normal modes and Galerkin method. Stationary convection is shown to be the preferred mode of instability when the ratio of strain retardation parameter to stress relaxation parameter is greater than unity. When the ratio is less than unity then the possibility of oscillatory convection is shown to arise. Oscillatory convection is studied numerically for Rivlin-Ericksen, Maxwell and Jeffreys liquids by considering free-free, rigid-rigid and rigid-free isothermal/adiabatic boundaries. The effect of variable viscosity parameter is shown to destabilize the system. The problem reveals the stabilizing nature of strain retardation parameter and destabilizing nature of stress relaxation parameter, on the onset of convection. The Maxwell liquids are found to be more unstable than the one subscribing to Jeffreys description whereas the Rivlin-Ericksen liquid is comparatively more stable. Free-free adiabatic boundary combination is found to give rise to a most unstable system, whereas the rigid isothermal rigid adiabatic combination gives rise to a most stable system. The problem has applications in non-isothermal systems having viscoelastic liquids as working media. © 2009 Elsevier Masson SAS. All rights reserved.

This paper presents a way to build a Multi-colored line following and obstacle avoiding helicopter using 4 infrared sensors. This helicopter is built on an ATmega8 microcontroller which has been programmed using Arduino. It has 1 infra-red sensor (LM358) below it in-between the landing gears, one infra red sensor to its left, one to its right and one at front to detect obstacles. It has 3 DC motors, two at the top and one at the rear. There are 2 H-bridges (L293D) mounted on it to provide the driving mechanisms for the motors. Three DC motors with rated voltage of 3.7V are used. Once the helicopter has been turned on, it rises about 5cms above the ground and goes straight and left until a line has been detected by the sensor. It then starts going straight right until the sensor stops encountering the line. If at all at any point of time any of the sensors detect an obstacle it will stop until the obstacle has been removed. It continues doing this until there is no line to follow in which case it continues going in a straight and left way or it has been brought to rest by switching it off. © 2011 IEEE.

In the present study the wear behavior of aluminium alloy LM25 reinforced with SiC particulate and further addition of TiO2 particulate fabricated by stir casting process is investigated. The wear resistance and frictional properties of hybrid metal matrix composite are studied by performing dry sliding wear test using a pin on disk wear tester. The experiments are conducted at a constant sliding velocity of 1.04m/s and sliding distance of 628m over a various load of 3,4,5kg for addition of particulate volume fraction of SiC 7.5% and increase in volume fraction by 2.5% & 5% TiO2. The results show that, the reinforcement of the metal matrix with SiC and TiO2 reduces the wear rate at room temperature. An attempt has also been made by keeping SiC percentage constant and increasing the TiO2 percentage it also proves wear rate decreases as the TiO2 content increases. The results also indicate that the wear of the test specimen increases with the increasing load and sliding distance. The coefficient of friction decreases with load and increasing volume content of reinforcement. The worn surfaces are examined by Scanning Electron Microscope to study the wear mechanism. At high speeds mechanical mixed layer (MML) and lubricating property of TiO2 exhibits between the composite pin and steel and thereby reducing the wear rate. The wear mechanism changes from severe abrasive wear to mild oxidative wear as the distance increases. © 2013 The Authors. Published by Elsevier Ltd.

A study has been carried out to investigate the tensile, flexural and dielectric properties of composites made by reinforcing vakka as a new natural fibre into a polyester resin matrix. The fibres extracted by retting and manual processes have been used to fabricate the composites. These composites are tested for tensile, flexural and dielectric properties and compared with those of established composites like sisal, bamboo and banana made under the same laboratory conditions. The composites are fabricated up to a maximum volume fraction of fibre of 0.37 in the case of tensile testing, and 0.39 for flexural and dielectric testing. It has been observed that the tensile properties increase with respect to volume fraction of fibre for vakka fibre composite and are also more than those of sisal and banana composites and comparable to those of bamboo composites. The flexural strength of vakka fibre composite is more than that of banana composite and is closer to sisal fibre composite with respect to the volume fraction of fibre, where as the flexural modulus is much higher than those of banana and sisal fibre composites and also very much closer to bamboo fibre composites. The dielectric strength of vakka fibre composite increases with increase in volume fraction of fibre in the composite unlike the case of sisal, bamboo and banana composites. The dielectric strength being a unique feature of vakka fibre composite, can be suggested for electrical insulation applications. © 2009 Elsevier Ltd. All rights reserved.

In this paper, an economic order quantity model for deteriorating items with time discounting has been developed for varying demand pattern over a fixed planning horizon. Optimal solutions with complete backlogging and without backlogging are established and has proven that the total variable cost is convex. The main contribution of this paper is based on the assumption of the demand which is the linear function of the instantaneous stock level I(t). In this paper, a new type of demand has been considered which will help us to obtain qualitative insights without much analytical complexity. Optimal solutions of the proposed models are derived and effects of deterioration on the inventory replenishment policies are studied with the help of numerical examples. © 2011 Springer-Verlag London Limited.
