As transistor counts and clock frequencies increase, distributing a low-skew global clock becomes increasingly more difficult. Iyer and Marculescu studied GALS-based microprocessors and concluded that they could gain power advantages by allowing fine tuning of the supply voltages and clock speeds for different functional blocks and by eliminating the need for a global, low-skew clock.Crossing clock domains is the central problem in GALS designs. If the data for a flip-flop or latch comes from...
Android is based off Linux software. For a few people they think Android is just an operating system for their cellular devices but it also helps middleware and key applications. Most of the devices that this software powers are usually touchscreen devices such as smartphones and tablet computers. With such success it is now able to power other devices such as televisions, netbooks and cameras. Android powers hundreds of millions devices in over 190 countries around the world. It was considered...
In this chapter we present a brief overview about mobile ad hoc networks and, in the following section we start with a brief description of distributed systems which is a computational model commonly used in the design of self-stabilizing algorithms. In section 2.3 we will give an overview about self-stabilization which is a very active area of research. 2.1 MANET Mobile ad hoc networks are formed dynamically by an autonomous system of mobile nodes that are connected via wireless links without...
SQL Server 2005 : SQL Server is a relational database management system (RDBMS) developed by Microsoft thats designed specifically for the enterprise environment. SQL Server runs on T-SQL (Transact -SQL), a set of programming extensions from Sybase and Microsoft with some additional features to standard SQL, including transaction control, exception and error handling, row processing, and declared variables. Oracle 9i : Oracle is a relational database management system (RDBMS) from...
American Pharmacorp is a pharmaceutical manufacturing company that was established in 1995. This company manufactures herbal, cosmetics and pharmaceutical products. One of the few companies in Trinidad that has herbal products registered with the Food and Drug for legal sale in the country. It is a pioneer and leader in the nutraceutical in Trinidad and Tobago. It manufactures scientific validated herbal products that are registered with the Food and Drug Authorities and also conventional...
As digital technology has matured, analog discrete components have been replaced with the digital discrete, then with the integrated circuits(IC's) plus software, after this creation of microprocessor and these were implemented with standard processors and software. As these developments followed for low speed signal processing as a result it leads to overall development in the field of discreet signal processing (DSP), at this point dream of multimode band wireless systems became attainable...
There are two different tasks in explaining a software in detail. First, analyze the Software and assess the quality of that software. Then present those results to the software engineers.a tool, VizzAnalyzer is used for the detailed examination and illustration of software. Its illustration does not allow for a qualitative diagram representation. Therefore it is problematic task for others to understand it, and we need to explain the meaning of non-standard diagram elements.This problem can...
Internet became a vital part in day to day life for wide-ranging population for many purposes like business transaction, instructive purpose etc. Since many organizations rely on online business transactions there is a need for their database to get secured from intruders. Every organization uses web application for accessing their data from the database, these applications uses user inputs to create a query for storing, retrieving data from the database. Although all the organizations...
So the future point is to make Wi-Fi Hotspot more secure and an infrastructure, which everyone could use everywhere easily. The future belongs to Hotspots network, and for this reason the manufacturers looking for new ideas and applications, in order to provide more services to wireless users. About security, the manufactures start to incorporate into their Wi-Fi Hotspot networks the NAC (Network Access Control) protocol. NAC is a protocol, which try to control the access of an endpoint in a...
In this report, the features of the OpenCL framework are described. The matrix multiplication problem is picked for investigating the computation performance of GPU. The resultant implementation features at most 100 times speedup. Conclusions are drawn from the test results, which reflect the effects of using shared memory, different data types, and different workgroup sizes. Introduction Motivation GPUs are manycore processors capable of handling tremendous computation and data throughput....
