  • Virtually every computing system today is part of a distributed system. Programmers, developers, and engineers need to understand the underlying principles and paradigms as well as the real-world application of those principles. Now, internationally renowned expert Andrew S. Tanenbaum – with colleague Martin van Steen – presents a complete introduction that identifies the seven key principles of distributed systems, with extensive examples of each. Adds a completely new chapter on architecture to address the principle of organizing distributed systems.

  • We now begin our look at building protocols using the basic tools that we have discussed. The discussion in this lecture will focus on issues of key establishment and the associated notion of authentication These protocols are not real, but instead are meant to serve just as a high-level survey Later lectures will go into specific protocols and will uncover practical challenges faced when implementing these protocols

  • Compact substation" is a general name for, in fact, outdoor operated substation. Our range includes different access, equipment arrangement, depending on client requirement (space availability, operation habits). Everywhere, where access and transportation facilities are a key factor, we offer a technique based on a light concrete technology micro-concrete & GRC. (Glass Reinforced Cement). With higher mechanical resistance than concrete, GRC is widely used in construction throughout the world, when weight is an important factor.

  • A query speller is crucial to search engine in improving web search relevance. This paper describes novel methods for use of distributional similarity estimated from query logs in learning improved query spelling correction models. The key to our methods is the property of distributional similarity between two terms: it is high between a frequently occurring misspelling and its correction, and low between two irrelevant terms only with similar spellings. We present two models that are able to take advantage of this property. ...

  • The fishery of the Mekong River is one of the largest and most significant in the world, and most of the production is based on migratory river fishes. An earlier report provided an overview of the general patterns of fish migrations and their significance for management. This complementary report provides more detailed information on 40 key species which are significant in the Mekong River fishery. For each species we provide notes on distribution, feeding, size, population structure, critical habitats, life cycle and its importance in fisheries.

  • One key distinction is that business angels invest their own funds, unlike VC funds, who primarily invest funds committed by others (e.g. institutional investors). For this reason they typically invest in companies with which they can maintain close contacts (OECD, 2006). Furthermore, typically companies that receive BA financing are smaller (i.e. in terms of turnover – see also table 1 later in this text) than VC backed companies. Most of the companies that receive BA financing, do not receive VC financing at the same time.

  • The current study was undertaken in a new manufactured house set up as a research facility. The plan was to conduct longitudinal measurements of VOC concentrations in the house along with measurements of key physical parameters including house air change rate, indoor and outdoor temperature and relative humidity, and wind conditions over a period of approximately one year. The primary objective was to evaluate changes in the emissions of formaldehyde and other VOCs in response to time, house air change rate, and the other parameters.
