BATCH PROCESSING AND REAL TIME PROCESSING: MERITS AND DEMERITS

ABSTRACT The needs of real-time software require the use of one or more synchronous programming languages, real-time operating systems, and real-time networks which provide the essential frameworks on which to build a real-time software application. Few technologies can help improve business responsiveness as dramatically as real time processing of event data. By implementing real time processing solutions to monitor streaming data as it enters your organization, you can identify new opportu...

APPLICATION OF FUZZY LOGIC IN AN ELEVATOR

ABSTRACT An elevator group supervisory controller is a control system that manages systematically two or more elevators in order to serve passengers as required. The elevator cars are assigned accordingly in response to hall calls, so as to optimize waiting time, riding time, power consumption, passengers’ comfort, etc. In this paper, the simplicity of ordinal structure fuzzy logic in making crucial supervisory control decisions is demonstrated. In addition, in order to further improve...

APPLICATION OF EXPERT SYSTEM

ABSTRACT Computers have been in existence for some time. Personal computers have emerged in the early eighties and changed substantially the way corporations perform their functions. Large quantity of application software, tools making the computer more useful, have been developed over the years. Different classes that describe application software, such as "Spreadsheets", "Word Processors" and "Data Bases", are now as much a part of our vocabulary as "fax" and "cellular phone" machines.  A...

ANALOGUE TO DIGITAL CONVERSION SYSTEM THEORY AND APPLICATION

ABSTRACT Digital signals propagate more efficiently than analog signals, largely because digital impulses, which are well-defined and orderly, are easier for electronic circuits to distinguish from noise, which is chaotic. This is the chief advantage of digital modes in communications. Computers "talk" and "think" in terms of binary digital data; while a microprocessor can analyze analog data, it must be converted into digital form for the computer to make sense of it. A typical telephone mo...

ADVANTAGES AND DISADVANTAGES OF OFF THE SHELF SOFTWARE AND CUSTOMIZED SOFTWARE

ADDRESSING PRINCIPLES USED IN TCP/IP PROTOCOLS

ABSTRACT Network administrators need a thorough understanding of both types of addressing to administer Transmission Control Protocol/Internet Protocol (TCP/IP) networks and troubleshoot TCP/IP-based communication. This chapter discusses in detail the types of Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) addresses, how they are expressed, and the types of unicast addresses assigned to network node interfaces. We demonstrate that the dynamic behavior of queue and ...

A SECURITY GATEWAY

ABSTRACT In the context of computer networking, an application-level gateway (also known as ALG or application layer gateway) consists of a security component that augments a firewall or NAT employed in a computer network. It allows customized NAT traversal filters to be plugged into the gateway to support address and port translation for certain application layer "control/data" protocols such as FTP, Bit-Torrent, SIP, RTSP, file transfer in IM applications etc. In order for these protocols ...

Since there is constrain in time, this project wil...

DESIGN AND CONSTRUCTION OF AN ELECTRIC DICE DISPLAY WITH AUDIO UNIT.

This work deals extensively with the design and construction of an electrodice display (EOD) with audio unit. The device displays the value of a ludo dice in numerical form and also produces sound as it displays the number. The device works with principle of chance employed by ludo game players. The output of the display is usually very rapid that the player does not actually see the number when the device is switched ON so that it will purely be a game of chance. When the off key is pressed,...
