Swarm Intelligence Based Data Mart Maintenance
No full textData mart is the concise and user specific version of data warehouse. It is basically a confined data warehouse for manipulator to access data of his interest. The data within data mart is used to make strategic decision which relies severely on the accurate repossession of details. Therefore it is essential to brush up the data mart periodically so that the end user gets updated and accurate information. To accomplish this purpose, an efficient and effective method is required for optimizing the process of maintenance. This paper presents an algorithm to maintain the data mart using ant colony optimization. This algorithm uses the concept of clustering and meta-heuristic techniques to maintain and search the element in the data mart. The paper discusses the proposed algorithm for protein data bank and shows the effectiveness of the algorithm to maintain the data mart. The searching time is the main issue of concern. The technique described in the paper reduces the search time effectively

Optimization of Area, Power & Delay By Using Efficient Digit Serial FIR Filter
No full textIn the endure three decades, number of active rule for solving a problem in step and constructions have been introduced for the design of low complexity bit-parallel multiple constant multiplications (MCM) operation which explain the difficulty of different digital signal processing systems. Instead small debate has been given to the digit-serial MCM design that gives low complexity MCM operations although at the cost of rising delay. In this paper, we pitch the problem of minimizing the gate-level area in digit-serial MCM designs and present high-level synthesis algorithms, design constructions, and a computer aided design tool. Experimental outcomes show the efficiency of the given optimization algorithms and of the digit-serial MCM architectures in the design of digit-serial MCM operations and finite impulse response filters. The common approaches to the implementation of digital filtering algorithms are general purpose digital signal processing chips for audio applications, or special purpose digital filtering chips and application-specific integrated circuit for high rate
Dynamic Analysis and Design of Motorcycle Mounting System Subjected to Road Loads
Get PDFThis paper presents a comprehensive model of a motorcycle mounting system. The model presented herein consists of two main assemblies. The powertrain assembly and the swing-arm assembly are modeled as a six degree of freedom rigid bodies. The two assemblies are connected to each other using a shaft that is usually referred to as the coupler. The connection points on both assemblies are known.Unlike automobiles, motorcycle performance and handling is highly affected by the external disturbance. In addition to minimizing the shaking loads, the mounting system must be set up such that it also minimizes the external disturbance from the environment such as irregularities in the road profile and road bumps. This disturbance can be transmitted through the tire patch to the engine causing it to hit nearby components. The engine movement needs to be minimized due to space limitations surrounding the engine. In order to do so, these transmitted external loads must be minimized by the use of the mounting system. The load minimization process is achieved by selecting the optimum stiffness parameters, location and orientation of the mounting system that are supporting the engine. This goal is achieved by an optimization scheme that guarantees that the transmitted loads are minimized. An investigation will be done to explore the effect of different road profiles on the mount final geometrical shape
Step Down Converter With Efficient ZVS Operation
No full textStep down converters has many applications in modern electronic devices. For these purposes, circuits have voltage/current requirements outside the efficient range of most classical converters. Therefore there was an urge for development of new converter topologies. Converters employing soft switching methods were emerged as an efficient alternative while considering the switching losses of a conventional converter. Here modifications are made on conventional buck converter. An auxiliary switch, a diode, and a coupled winding to the buck inductor are added with the conventional buck converter. By transferring the buck inductor current to the coupled winding in a very short period, a negative built-up of leakage inductor current in buck winding is achieved, which guarantees the Zero- Voltage Switching (ZVS) operation of the buck switch in all load conditions. Furthermore, since the negatively built-up leakage inductor current is minimized after the zero voltage of the buck switch is achieved; the unnecessary current build-up and the conduction loss are minimized. Therefore, a converter with efficient ZVS operation with load variation is achieved. To verify the performance of this topology, simulations are done using MATLAB or SIMULINK
