Optimizing and Testing WLANs explores proven techniques for maximizing the coverage area and performance of wireless networks. The author's insider position on the IEEE committee developing standards for WLAN testing ensures timeliness and technical integrity of the material. The book includes coverage of newer multiple input/multiple output (MIMO) wireless networks. The techniques provided will allow engineers to help maintain continuous wireless connectivity to laptops and other mobile devices. Optimizing and Testing WLANs is the first book to address the need to test WLANs (Wireless Local Area Networks) for proper performance and to optimize their operation as they become increasingly common. It covers test equipment and methods for the RF (wireless) and physical layers of WLAN, protocols, the application layer, and manufacturing testing. The emphasis throughout is on underlying engineering principles along with modern metrics and methodologies, ensuring this book gives both a solid theoretical background along with field-proven techniques and applications. A particularly engaging chapter deals with manufacturing test that describes some of the different manufacturing test setups and equipment. A concise introduction to deployment testing of "hotspots" and WLANs in enterprises is also provided. This text will be of interest to RF wireless engineers and designers, networking engineers, IT professionals and managers, and graduate students. *Gives proven techniques for maximizing the coverage area and performance of wireless networks *Author's insider position on the IEEE committee developing standards for WLAN testing ensures timeliness and technical integrity of the material *Includes coverage of newer multiple input/multiple output (MIMO) wireless networks

The objective of this book is to present a comprehensive picture, first of the fundamentals of general contamination of solid surfaces and water, and in the second part, to review the main practical procedures and means of applied decontamination used in the fields of activity. The most emphasis on radioactive contamination deals with decontamination of the operational facilities in nuclear power plants. Other special decontamination branches of current interest are also dealt with briefly. The art of decontamination is being enriched by the progress achieved in relevant scientific disciplines and employs these relative advances. The current volume discusses in detail the following trends in decontamination: Firstly, the development and use of new decontamination methods that are highly efficient, non-agressive to decontaminated materials, and economically feasible; secondly, the utilization of progressive elements of automation and robotics; thirdly, the development and use of such decontamination formulations that would minimize the volume of wastes and would produce wastes in a form in which they could be either easily further treated or safely disposed of without risk to human health or the environment; finally, the choice of suitable materials used both for the structural and the technological parts of nuclear installations with regard to their minimal contaminability and ease of decontamination.

Burgos, the capital of medieval Spain and a lively city today, was a perfect venue to celebrate such an occasion. The conference has become a unique, established and broad int- disciplinary forum for researchers and practitioners in many fields to interact with each other and with leading academics and industries in the areas of machine lea- ing, information processing, data mining, knowledge management, bio-informatics, neuro-informatics, bio-inspired models, agents and distributed systems, and hybrid systems. IDEAL 2009 received over 200 submissions. After a rigorous peer-review process, the International Programme Committee accepted 100 high-quality papers to be - cluded in the conference proceedings. In this 10th edition, a special emphasis was given on the organization of workshops and special sessions. Two workshops were organized under the framework of IDEAL 2009: MIR Day 2009 and Nature-Inspired Models for Industrial Applications. Five special sessions were organized by leading researchers in their fields on various topics such as Soft Computing Techniques in Data Mining, - cent Advances on Swarm-Based Computing, Intelligent Computational Techniques in Medical Image Processing, Advances on Ensemble Learning and Information Fusion, and Financial and Business Engineering (Modelling and Applications).

The complete guide to using testing to minimize risk and reduce downtime in advanced enterprise networks * *When, what, and exactly how to test new products, solutions, and advanced technologies. *Authoritative answers to common questions about enterprise network testing, from test planning and resources to test outsourcing. *Includes sample test plans for branches, WANs/MANs, data centers, and campuses, as well as specific guidance for testing many network technologies. Enterprise networks are rapidly evolving from 'plumbing' into intelligent business application platforms. IT Managers must now meet business-driven Service Level Agreements, and testing has become crucial to meeting the expectation of near-zero downtime. Now, there's a comprehensive guide to all facets of enterprise network testing, not just security. Cisco enterprise consultants Andy Sholomon and Tom Kunath offer a complete blueprint that shows organizations when, what, and exactly how to test new products, solutions, and advanced technologies. Enterprise Network Testing presents best-practice methodologies and guidelines for both network system and solutions testing, helping professionals systematically minimize the risks of incurring downtime in new deployments by executing methodical test plans. The authors first explain how different levels of network testing can be leveraged to meet specific business goals. Drawing on their extensive experience with enterprise clients, they show how to build testing proofs of content; test features; test to ensure that a network is ready for use; and test both migration and security. Test plan samples are provided for key network locations including branches, WANs/MANs, the data center, and the campus. The authors also offer specific guidance on testing each of these technologies: MPLS/VPN, QOS, VoIP, video, security/IPSec VPNs, advanced routing (OSPF, EIGRP, BGP), and SANs.
