  • In response to a request by the Department of Homeland Security, the National Research Council formed an ad hoc committee to organize a two-day workshop to discuss the use of social network analysis (SNA) for the purpose of building community disaster resilience. The workshop was held February 11-12, 2009, in Washington, D.C., and engaged a group of approximately 30 researchers in the fields of SNA and resilience science as well as emergency management practitioners from different regions of the country.

  • Geographic Information System (GIS) analysis is basically spatial problem-solving. It can be quite challenging at first, especially if you get bogged down in syntax and details. The hardest part is to conceptually understand the problem, and the GIS tools available to solve your problem. This book will help you understand conceptually how various GIS tools work. So for now, forget about workspaces, libraries, spatial database engines, dangling nodes, fuzzy tolerances, requests and instances....

  • The performance of current transport systems is inadequate when viewed in terms of economic efficiency, sustainability, and safety. Towards Better Performing Transport Networks examines the tools that are necessary to effectively measure these systems and those that are required to improve them. Utilising advanced tools of network analysis, the contributors challenge various pieces of conventional wisdom and in particular the view that intermodal transport is more environmentally benign than road transport.

  • This paper brings a marriage of two seemly unrelated topics, natural language processing (NLP) and social network analysis (SNA). We propose a new task in SNA which is to predict the diffusion of a new topic, and design a learning-based framework to solve this problem. We exploit the latent semantic information among users, topics, and social connections as features for prediction. Our framework is evaluated on real data collected from public domain.

  • Chapter 15 - Network analysis, design, and implementation. In this chapter, we discuss the network development life cycle (NDLC) which consists of three phases: analysis, design, and implementation. We first discuss the cycle itself. We then discuss the steps in the analysis phase, the steps in the design phase, and finally the steps in the implementation phase.

  • Power flow solutions are needed in both for planning and operation studies. Power flow studies for three phases balanced power system can be carried out using very efficient methods. Power flow analysis for certain type of power system network can be carried on by using several software that already been develop without manual calculation on this time. One of the software is MATLAB with its toolbox: Power System Analysis Toolbox. This software also uses numerical methods to do power flow analysis like Newton-Raphson and its modified form, Fast Decoupled Method.

  • The objectives of this course are to introduce you to the fundamentals and benefits of using tcpdump as a tool to analyze your network traffic. We’ll start with introducing concepts and output of tcpdump. One of the most important aspects of using tcpdump is being able to write tcpdump filters to look for specific traffic. Filter writing is fairly basic unless you want to examine fields in an IP datagram that don’t fall on byte boundaries. So, that is why an entire section is devoted to the art of writing filters....

  • Security has become a major concern for every network administrator. Nearly every day we are bombarded with news articles describing yet another high-profile company that has fallen prey to a network-based attack. To fill in the occasional gap, we hear about new viruses that have been found “in the wild” or about additional software vulnerabilities that someone has figured out how to exploit for personal gain. The network security field has not always been this crazy. Most of us can remember a time when securing a network environment was a far easier task.

  • The protocol wars are over and TCP/IP won. TCP/IP is now universally recognized as the pre-eminent communications protocol for linking together diverse computer systems. The importance of interoperable data communications and global computer networks is no longer debated. But that was not always the case. When I wrote the first edition of this book, IPX was far and away the leading PC communications protocol. Microsoft did not bundle communications protocols in their operating system.
