Information Access Technology (IAT) software development, arabization, marketing and support, based on the Open Source Software (OSS) concepts and Web 2.0 trends. IAT applications include: Integrated Library Systems, Media Archiving Systems, Federated Search and Taxonomy/Foxonomy based Retrieval, Reference Linking (OpenURL), Document Delivery and Smart Knowledge Portals.
This document discusses simulation of OFDM modulation adapted for fixed image transmission over disturbed channels. It presents results from a MATLAB simulation of an OFDM system using various modulation schemes (BPSK, QPSK, 16PSK, 256PSK) with and without convolutional coding. The system is evaluated based on received image quality, SNR, BER, and other parameters when using a standard guard interval of 25% of the symbol period versus a modified shorter guard interval. Results show image quality of 98% can be achieved with the classic OFDM system using a 25% guard interval when convolutional coding is added to improve transmission quality over noisy channels.
The document discusses scanning techniques. It defines scanning as examining an area carefully but quickly, often to look for a particular person or thing. It then provides tips for how to scan effectively, such as scanning the margins and zigzagging the eyes across a page. The goal of scanning is to absorb essential information from a document in an efficient manner.

The document discusses types of computer networks and how they function. It describes peer-to-peer and client-server networks, and different types of area networks including LANs, WANs, CANs, and MANs. It also explains how networks connect to the internet using modems and ISPs, how information is transmitted over networks using protocols like TCP/IP, and how clients communicate with servers over the internet using domain names.
Network Scanning Phases and Supporting ToolsJoseph Bugeja
This presentation focuses on the network penetration scanning phase. It introduces tools and techniques that professional pen-testers and ethical hackers need to master to find target machines, openings on those targets and vulnerabilities.

This document discusses different types of programming applications including desktop, web, and mobile. It notes that desktop applications can be for informational or business purposes and run on Windows. Web applications can be only websites or websites with additional systems, while mobile applications are available for Android, iOS, and Windows Phone platforms.
This document contains notes from a Cisco Certified Network Associate (CCNA) training course covering networking topics such as IP subnetting, routers, routing, access lists, switching, VLANs, NAT, wireless LANs, IPv6, and WANs. The notes provide definitions and explanations of key concepts, such as what a subnet is, the benefits of subnetting, IPv4 addressing rules, and the different classes of IP addresses. Examples and configuration instructions are also included for various networking devices and protocols.
