TL;DR: The subject addressed here is the reliable detection, at the communications receiver, of the individual bits when interference is present, so that the information carried by the sequence of data bits can be recovered.
Abstract: M ODERN military communications systems are , increasingly adopting the digital method of transmitting information. In a digital communications (or data) link, the information to be sent is represented by a sequence of electronic pulses. In the simplest form of digital signal transmission, these pulses are referred to as binary digits, or “bits.” Each pulse, or bit, is the smallest amount of data that can be communicated, and the messages to be sent ‘are composed of larger sets of these bits. The manner in which message information is imparted to the data bits is the subject of information modulation, a topic well covered in most basic texts on communications.” The subject addressed here is the reliable detection, at the communications receiver, of the individual bits when interference is present, so that the information carried by the sequence of data bits can be recovered. The time duration of a data bit implies a minimum bandwidth capability for the communications link. Thus, it is important to understand the basic concept of bandwidth involved in any criteria for reliable reception.

TL;DR: An evaluation against a manually categorized ground truth news corpus shows the TopCat technique is effective in identifying topics in collections of news articles.
Abstract: TopCat (Topic Categories) is a technique for identifying topics that recur in articles in a text corpus. Natural language processing techniques are used to identify key entities in individual articles, allowing us to represent an article as a set of items. This allows us to view the problem in a database/data mining context: Identifying related groups of items. This paper presents a novel method for identifying related items based on “traditional” data mining techniques. Frequent itemsets are generated from the groups of items, followed by clusters formed with a hypergraph partitioning scheme. We present an evaluation against a manually-categorized “ground truth” news corpus showing this technique is effective in identifying topics in collections of news articles.

TL;DR: A comprehensive survey of the past and current work on advance reservation for optical networks is provided and there have been many variations of the advance reservation concept proposed, so a broad classification is provided.
Abstract: Traditionally, research on routing and wavelength assignment over wavelength-routed WDM networks is concerned with immediate reservation (IR) demands. An IR demand typically does not specify a holding time for data transmission and the start time of the data transmission is assumed to be immediate (i.e. when the connection request arrives). The concept of advance reservation (AR) has recently been gaining attention for optical networks. An AR demand typically specifies information about the start of the data transmission or a deadline, as well as the holding time of the transmission. AR has several important applications for both wide-area networks and Grid networks. For example, AR can be used for adjusting virtual topologies to adapt to predictable peak hour traffic usage. It can be used to provide high-bandwidth services such as video conferencing and in Grid applications requiring the scheduled distribution of large files and for co-allocation of network and grid resources. AR can also be beneficial to the network by allowing the network operator to better plan resource usage and therefore increase utilization. Knowledge of the holding time can lead to more optimal decisions for resource allocation. This translates to better quality of service for users. In this paper we provide a comprehensive survey of the past and current work on advance reservation for optical networks. There have been many variations of the advance reservation concept proposed, so we will also provide a broad classification. In addition to the survey, we will discuss what we believe are important areas of future work and open challenges for advance reservation on optical networks.

TL;DR: Cyber Situational Awareness: Issues and Research as discussed by the authors is an edited volume contributed by worldwide cyber security experts to establish state of the art in cyber situational awareness area to set course for future research.
Abstract: Today, when a security accident occurs, the top three questions security administrators would ask are in essence: What has happened? Why did it happen? What should I do? Answers to the first two questions form the "core" of Cyber Situational Awareness. In addition, whether the last question can be well answered, is greatly dependent upon the cyber situational awareness capability of enterprises. Cyber Situational Awareness: Issues and Research is an edited volume contributed by worldwide cyber security experts. This book seeks to establish state of the art in cyber situational awareness area to set course for future research. A multidisciplinary group of leading researchers from cyber security, cognitive system, and decision science areas will elaborate on the fundamental challenges facing the research community and identify promising solutions paths. Case studies based on real world examples are provided throughout this book. Cyber Situational Awareness: Issues and Research is designed for a professional audience composed of government workers and practitioners working in the field of cyber security. Advanced-level students and researchers studying computer science will also find this book useful, as secondary text or a reference book.
