 Abstract

This document explains the impact of autonomous vehicles on society. The project includes a background section which gives information about the history and technology of autonomous vehicles. To evaluate the socio-economic effect of the autonomous vehicles, we review the benefits and economic savings that will emerge as a result of the introduction of autonomous cars in the economy. Impacts on safety, traffic flow, fuel economy, professional driving and culture are some of the important issues mentioned in this report.

 Abstract

In This paper presents a design of Slope compensation in Dc-Dc flyback converter. Current mode control as usually implemented in switching power supplies senses and controls peak inductor current. Current mode control have cycle to cycle peak current limit, inherent voltage feed forward loop and simplified loop compensation. Flyback converter operates in peak current mode, which is suffer from instability, and sub-harmonic oscillation, when it operates in continuous conduction mode and the duty cycle is greater than the 50% .We analyze the slope compensation method for reducing the sub-harmonic oscillation and enhances the stability and to provide the feed forward property. Experimental result shows the value of M (slope) or ramp signal. Simulation result gives the less harmonic in the system and inductor current waveform with and without compensation.

 Abstract

The earliest way to managing electronic data in hard hard-drive is File System. In a typical File System electronic data are directly stored in a set of files. If only one table is stored in a file, they are called flat files. They contain values at each row seprated with a special delimiter like commas. The burden of locating the necessary file, going through the records ( line by line ) checking for the existence of a certain data, remembering what files/records to edit is on the user. The user either has to perform each task manually or has to write a script that does them automatically with the help of the file management capabilities of the operating system. Because of inconsistency, inability for concurrency, data isolation, threats on integrity and lack of security the File Systems are vulnerable

 Abstract

The basic principle of inventory control is ABC based on cost criteria. The objectives of this study are to identify the categories of spare items requiring greater managerial control, because not all inventories need to be controlled with equal attention. Another most important objective is to ensure continuous availability of stores to user departments while keeping the stock levels at optimum level is one of the important objectives of Stores Department. The study was conducted at a single ward of store depot SECR Raipur. From 189 items of spare, 17 items (8.99%) consume 70.56% of annual value and clasified into class A, 40 items (21.16%) consume 19.35% of annual value classified into class B, and 132 items (69.85%) of annual value consume only 10.09% forming class C. The results showed that there was items of class Amay warrant more care than forecasting class B and class C.

 Abstract

The usage of the FPGA (Field Programmable Gate Array) for neural network implementation provides flexibility in programmable systems. For the neural network based instrument prototype in real time application, conventional specific VLSI neural chip design suffers specific VLSI neural chip design precision artificial neural network design, FPGAs have higher speed and smaller size for real time application than the VLSI design. In addition, artificial neural network based on FPGAs has fairly achieved with classification application.

 Abstract

This paper presents the results of an experimental research on the workability and compressive strength of ordinary and standard concrete. The work focused on concrete mixes having water/cement ratios of 0.50 with different grade of concre dosages of a superplasticizer 0.2%, 0.4% and 0.6% by weight of cement based on carboxylic. The workability tests utilized in this research were the slump flow and compacting factor test dispersants to avoid particle aggregation, and to improve the flow characteristics of suspensions such as in directly improves the performance of the fresh and hardened state of concrete. In this project for a pa percentage of superplasticizers from 0.2% to 0.6% various mixes are design by IS 10262:2009. considered. The graphs between percentage of superplasticizers with W/C ratio, CF and strength are plotted. Same work is done with other grades of concrete also.

This paper presents a new five level diode clamped multilevel inverter topology which can be used for low-medium power industrial applications. In this work proposes single phase five level Diode Clamped Multilevel Inverter (DCMLI) topology using an auxiliary switch is presented, the number of power devices required to implement a five-level output. The topology is tested in the design of a 5 levels diode clamp multilevel inverter simplified; circuit operation is presented, simulated and validated with experimental tests performed on a laboratory prototype. In this paper, the concept of a 5-level diode-clamp and modulate principle are implemented to control the output waveform approaching to the sine-wave as close as possible. The simulation result, the output voltage waveform presents better harmonics profile.

 Abstract

The Mining Database archives and provides efficient access to all data necessary for the conduct of Survey Operations. Operational Database is the database-of-record, consisting of system-specific reference data and event data belonging to a transaction-update system. It may also contain system control data such as indicators, flags, and counters. The operational database is the source of data for the data warehouse. It contains detailed data used to run the day-to-day operations of the business. The data continually changes as updates are made, and reflect the current value of the last transaction. Data Warehouse Systems make use of storage techniques for efficient end user accessing and query facilities. With the evolution of semantic data representation in the operational database environment, the accomplished analysis in DWS demands new synchronism ways. The proposed algorithm uses the principle of Bernoulli trials to find expected frequent itemsets. This can reduce a number of times to scan an original database. Assuming that the minimum support and confidence do not change, the algorithm can maintain association rules for a dynamic database. We proposing a probability-based new association rule discovery algorithm are to deal with from a different perspective other than similar techniques. The proposed algorithm uses the principle of Bernoulli to find expected frequent itemsets. Hence, there is a growing interest in DWS that can rapidly absorb the operational database updates, without compromising the operational query processes.
