Abstract: Hydraulic cylinder actuators are used extensively in industrial, construction and agricultural works. The small sized outlet ports of the cylinders resist the flow of discharged oil; and as a result the piston motion is slowed down. This causes a lot of heat generation and energy loss within the actuators. The study investigates and analyzes the possibilities of reducing the hydraulic resistance and increasing efficiency of the hydraulic actuator. Conventional hydraulic cylinders are simulated in FLUENT. Results show that the small outlet ports are the sources of energy loss in hydraulic cylinders. A new hydraulic system was proposed as a solution to relieve the hydraulic resistance in the actuators. The proposed system is a four ports hydraulic cylinder fitted with a novel flow control valve. The proposed four ports cylinder was simulated and parameters such as ports sizes, loads and pressures are varied during the simulation. The hydraulic resisting forces, piston speed and mass flow rates are computed. Results show that the hydraulic resistance is significantly reduced in the proposed four ports actuators; and the proposed cylinders run faster than the conventional cylinders and a considerable amount of energyis saved as well. Key words: Computational Hydraulic, Energy Efficient Actuators, Energy Saving in Hydraulic, Hydraulic Control

Abstract: Analysis of the robot hand was analyzed using dedicated software for FEM analysis. The model was exported to FEM processor i.e. in ANSYS, the geometry was updated and the structure meshed using 3D elements. Finiteelement analysis is a method to computationally model reality in a mathematical form to better understand a highly complex problem. In the real world, everything that occurs results from the interaction between atoms (and sub-particles of those atoms). Billions and billions and billions of them. If we were to simulate the world in a computer, we would have to simulate this interaction based on the simple laws of physics. However, no computer can process the near infinite number of atoms in objects, so instead we model 'finite' groups of them. Key words: robot hand, Robotics, Robot Finger, Finger joints, FEA modeling.

Abstract: Leprosy or Hansen's disease is caused by an obligate intracellular pathogen i.e. Mycobacterium leprae. Leprosy is a granulomatous disease of peripheral nerves and mucosa of the upper respiratory tract. This infectious disease results in Leprosy reactions that cause irreversible nerve damage and disabilities. The organism requires minimal set of functional genes for its survival. Most of the genes are involved in biosynthetic and metabolic pathways, so the product of these genes can be aimed for the novel drug target. Acyl CoA Synthetase is an enzyme that participates in fatty acid biosynthesis. The activation of fatty acids by Acyl-CoA Synthetase is the need of de novo lipid biosynthesis, fatty acid catabolism and remodeling of biological membranes. Therefore by emphasizing this protein as a drug target can help in the identification of novel drugs to cure leprosy. A well organized research comprising of analogue based drug design and molecular dynamics plays a major role in obtaining the lead molecules. The bacteria have developed resistance against many of the drugs available in the market. Therefore identification of the novel drug target and potent drug can be helpful in better prevention of the disease. Key words: docking, homology modeling, leprosy, M.leprae, molecular, molecular dynamics, ramachandran plot.

Abstract: For dynamic optimization problems, the aim of an effective optimization algorithm is both to find the optimal solutions and to track the optima over time. In this paper, we advanced two kinds of cellular genetic algorithms inspired by the density dependence scheme in ecological system to solving dynamic optimization problems. Two kinds of improved evolution rules are proposed to replace the rule in regular cellular genetic algorithm, in which null cells are considered to the foods of individuals in population and the maximum of living individuals in cellular space is limited by their food. Moreover, in the second proposed rule, the competition scheme of the best individuals within the neighborhoods of one individual is also introduced. The performance of proposed cellular genetic algorithms is examined under three dynamic optimization problems with different change severities. The computation results indicate that new algorithms demonstrate their superiority respectively on both convergence and diversity. Key words: cellular genetic algorithm, dynamic optimization, density dependence scheme

Abstract: This paper introduces a new concept of optimal utilization of a unified power quality conditioner (UPQC). The series inverter of UPQC is controlled to perform simultaneous 1) voltage sag/swell compensation and 2) load reactive power sharing with the shunt inverter. The active power control approach is used to compensate voltage sag/swell and is integrated with theory of power angle control (PAC) of UPQC to coordinate the load reactive power between the two inverters. Since the series inverter simultaneously delivers active and reactive powers, this concept is named as UPQCS (S for complex power). A detailed mathematical analysis, to extend the PAC approach for UPQCS, is presented in this paper. MATLAB/ SIMULINK -based simulation results are discussed to support the developed concept. Finally, the proposed concept is validated with a digital signal processor-based experimental study. Key words: Active power filter (APF), power angle control (PAC), power quality, reactive power compensation, unified power quality conditioner (UPQC), voltage sag and swell compensation.

Abstract: Induction heating is a well-known technique to produce very high temperature for applications. A large number of topologies have been developed in this area such as voltage and current source inverter. Recent developments in switching schemes and control methods have made the voltage-source resonant inverters widely used in several applications that require output power control. The series-resonant inverter needs an output transformer for matching the output power to the load but it carry high current as a result additional real power loss is occur and overall efficiency also is reduced. This project proposes a high efficiency LLC resonant inverter for induction heating applications by using asymmetrical voltage cancellation control .The proposed control method is implemented in a full-bridge topology for induction heating application. The output power is controlled using the asymmetrical voltage cancellation technique. The LLC resonant tank is designed without the use of output transformer. This results in an increase of the net efficiency of the induction heating system. The circuit is simulated using MATLAB .The circuit is implemented using PIC controller. Both simulation and hardware results are compared. Key words: Asymmetrical control, induction heating, zero-voltage switching (ZVS).

Abstract: The corruption of speech due to presence of additive background noise causes severe difficulties in various communication environments. This paper addresses the problem of reduction of additive background noise in speech. The proposed approach is a frequency dependent speech enhancement method based on the proven spectral subtraction method. Most implementations and variations of the basic spectral subtraction technique advocate subtraction of the noise spectrum estimate over the entire speech spectrum. However, real world noise is mostly colored and does not affect the speech signal uniformly over the entire spectrum. This method provides a greater degree of flexibility and control on the noise subtraction levels that reduces artifacts in the enhanced speech, resulting in improved speech quality. Key words: spectrum, noise subtraction.

Abstract: As the digital infrastructure in cities and buildings are in place, new forms and methods of spatial (location) are also growing.In between computational architectures, such as topological spaces, and non-Euclidean geometry, dynamical systems and developmental movement algorithms are alternative technological architectures.As Peter Zellner said: architecture , has renovated itself .Part of that, is the scientific study of topological geometry, computational part of that, is the production of plastics and part of that, is the creative visualization deals Kinetic space.The era of information, such as the previous age, the metal industry, challenges not only the design itself but also how these designs are. Creative and productive potential of digital media has created a new dimension in architecture. Lvtsma Barrett says, instead of trying for emplacing the thought of the traditional architecture, our strategy should be such that the architecture can integrate with other Medias to create a new link Reference

Abstract: The Flexible AC Transmission System (FACTS) technology is a promising technology to achieve complete deregulation of Power System i.e. Generation, Transmission and Distribution as the complete individual units. FACTS is based on power electronic devices, used to enhance the existing transmission capabilities in order to make the transmissionsystem flexible and independent in operation. The loading capability of transmission system can also be enhanced nearer to its thermal limit without affecting the stability. Complete closedloop smooth control of reactive power can be achieved using shunt connected FACTS devices. Static VAR Compensator (SVC) is one of the shunt connected FACTS devices, which can be utilized for the purpose of reactivepower compensation. As the Intelligent FACTS devices make them adaptable, it is emerging as the present state of the art n technology. This paper presents the design and simulation of the Fuzzy logic control to vary firing angle of SVC in order to achieve better, smooth and adaptive control of reactive power in transmission systems. The design, modeling and simulations are carried

Abstract: Signalized intersections have a great role in urban transportation and safety. Despite undeniable task of these traffic elements, they are facing many problems such as delays, inappropriate designing, miss using of traffic signs due to locations and dimensions at them. Besides these problems, the existence of traffic police at intersections is not always help to decrease these problems, but also can create more difficulties to the task of signalized intersections which might not obviously visible. For example the traffic police change cycle time and preventing some direction to cross the intersection and let some others cross which may cause more delays and other difficulties for regular and organized movement of vehicles. This study aims to investigate the above problems and find a solution to decrease them. For this purpose, a unique survey designed to analyze the four intersections in Tehran. These intersections selected from one arterial street and the specification of these intersections are somehow the same. The result shows that by changing the behavior of police in these intersections with correct training of traffic rules , can improve the traffic and decrease the delays. Key words: signalized intersections, police, traffic, delays.

Abstract: Aiming at the security requirement of the Intranet that is different from Internet, an security architecture for Intranet is proposed. In physical layer and data link layer, based on network switch the intranet is divided into several parts separated from each other as required. In network layer, making use of the NAT gateway integrated in virtual server the intranet or its part is hidden to ensure its security, and at the same time the other part of the intranet can securely access to the part of hidden resources. Using reliable IP address management and distribution mechanism the IP addresses are kept from being stolen or abused. In application layer, using bi -directional proxy server each part of the Intranet is separated, but the hosts can access each other based on application and user authority. The security switches are used to connect each separate part of the Intranet, based on application as well as user authorization control to carry out network access control. The security architecture focuses on security guarantee of intranet inside the traditional network boundary, and provides foundation framework to Intranet security which can ensure the reliability, usability, confidentiality, integrity, and maneuverability of the Intranet. Key words: Network Security; NAT Gateway; Bi-directional Pro; IP Address Management

Abstract: To achieve seamless mobility in unified network of heterogeneous wireless networks, vertical handoff is challenging problem. In this paper, we compare three vertical handoff algorithms, namely, HNE ( Handoff Necessity Estimation ) which determines the necessity of making a handoff to an available network and which works well for WLAN to cellular networks and vice versa, ALIVEHO ( Adaptive Lifetime based Vertical Handoff ) which uses RSS and expected duration after which the MT will be able to maintain its connection with WLAN to decide the vertical handoff and ARSST ( Adaptive RSS Threshold ) which achieves lower false handoff initiation probability and well suited for handoff from WLAN to 3G network. All these three algorithms are based on RSS and minimize the probability of false handoff. Key words: ALIVEHO, ARSST, False Handoff, HNE, RSS

Abstract: In this context of changing and challenging market requirements, Gas Insulated Substation(GIS) has found a broad range of applications in power systems for more than two decades because of its high reliability, easy maintenance and small ground space requirement etc. SF6 has been of considerable technological interest as an insulation medium in GIS because of its superior insulating properties, high dielectric strength at relatively low pressure and its thermal and chemical stability. SF6 is generally found to be very sensitive to field perturbations such as those caused by conductor surface imperfections and by conducting particle contaminants. A study of CIGRE group suggests that 20% of failure in GIS is due to the existence of various metallic contaminations in the form ofloose particles. The presence of contamination can therefore be a problem with gas insulated substations operating at high fields. If the effects of these particles could be eliminated, then this would improve the reliability of compressed gas insulated substation. It would also offer the possibility of operating at higher fields to affect a potential reduction in the GIS size with subsequent savings in the cost of manufacture and installation. The purpose of this paper is to develop techniques, which will formulate the basic equations that will govern the movement of metallic particles like aluminum, copper in a coated as well as uncoated busduct. Key words: GIS, Busduct, Particle Contamination

Abstract: In recent years, the areas of industrial application of AC drives, especially Induction machine based on DTC technique has gradually increased due to its advantages over the other techniques of control. In conventional direct torque control, the selection of flux linkage & electromagnetic torque errors are made within the respective flux and torque hysteresis bands in order to obtain fast torque response, low inverter switching frequency and low harmonic losses. However conventional DTC suffers from high torque ripple and variable switching frequency.This paper, propose a method to reduce torque fluctuations, where the circular flux vector is divided into twelve sectors and is compared with conventional DTC method where the flux vector is divided into six. The twelve sectors DTC method is simulated by using MATLAB/simulink package which represent the reduction of torque repulsions Key words: Induction machine, DTC, Twelve sector

Abstract: The paper deals with the reusability of command modules used during Apollo space missions. During Apollo missions in 1960-70's the module surface becomes charred up to some extent, hence decreasing the strength and scope of further reusability of the module. A new design has been proposed and simulation results have revealed the possibility to reuse the module again for another mission. The new design has incorporated an in-built mechanism that will extend some part of the module surface outwards near to the periphery of the base of the module. The design, mechanism, material and other details are discussed in succeeding sections. New ablative material has been introduced for more getting more promising results.

Abstract: Design patterns have been the target of a great deal of research in the last few years. A design pattern is a general solution to a commonly occurring problem[1]. They are composed of three parts: a problem context, a generalized approach to a solution, and a set of consequences. This paper concentrates on developing a catalog for design patterns for safety-critical real-time systems and allows flexibility to choose, search a design pattern and add more design patterns. To support the designers, a tool is developed to suggest the patterns that are appropriate for the software based on its characteristics/design problems. This tool will be able to help generate the code for the suitable design pattern. Key words: Design Pattern, Safety-Critical Real-Time Systems, Non-FunctionalRequirements, Safety-Critical Systems

Abstract: High-resolution signal parameter estimation is a significant problem in many signal processing applications. Such applications include direction of arrival (DOA) estimation for narrow band signals and wideband signal emitted by multiple sources and received by sensor arrays. It is well known that MUSIC algorithm outperforms any other method existing in the literature. In this article a modified MUSIC algorithm is proposed using the conjugate data. Strong consistency of the modified method is established. It is observed that the modified MUSIC works significantly better than the ordinary MUSIC at different SNR in terms of the mean squared error and for coherently sources. However, an important disadvantage of the ULA geometry in DOA estimation is that it can only estimate the azimuth angle. To estimate the elevation angle, Uniform circular arrays UCA geometries and planner array are employed in many applications. As the concentric circular arrays (CCA) that are discussed in this paper have better angle resolutions compared to ULAs,

Abstract: Forging is a forming method without any chips development, which is mainly used for serial produced machine parts with improved mechanical properties. A finite element method (FEM) model was developed to analyze the behavior of specimens made of the most commonly used aluminum alloy (EN AW-6082) in the Hungarian practice. Here an optimal forging model was searched for, moreover the connection between the variation of the mechanical properties and the scale of the deformation. An88 mm high cylindrical specimen of 90 mm diameter have been measured with 2 directional forming (it have been upset at 44 mm of its height), then samples were taken from it at different locations, and the local deformation with the change in the mechanical properties have been compared.

Abstract: In this paper we have presented an analytical model for power-aware, multi-hop wireless network nodes equipped with antennas such as omni directional, steerable and switched beam antennas. Complexity is day by day increasing of routing between the nodes because of highly dynamic nature of the mobile ad hoc network results due to frequent change in network topology. However, it may be possible to improve the network Congestion by using directional antennas. To find out which directional antenna gives better performance for mobile ad hoc networks, In this paper, we compare and analyze different directional antennas for various routing protocols such as DSR, OLSR, ZRP which comprise a good mix of reactive, proactive and hybrid protocols. To determined the average jitter, average end to end delay and throughput for application layer and power consumption between nodes in physical layer by using omni- directional, steerable and switched beam antennas. We are using Random waypoint mobility with rectangular frame in this simulation which is done with the QualNet 5.01 simulator. Key words: Ad hoc network, AODV, DSR, Directional antenna, QualNet, ZRP
