Es konnte gezeigt werden, dass eisenhaltiges Schaumglas in Kupfer- und Zinklosungen deren Konzentrationen in ahnlichem Rahmen senkt wie bereits auf dem Markt etablierte und wesentlich teurere Produkte. Es scheint also grundsatzlich als konkurrenzfahiges Produkt in Frage zu kommen, denn es steckt noch ein grosses Verbesserungspotenzial in diesem Verfahren. Die Entwicklung eines Adsorbens aus modifiziertem Schaumglas steht erst am Anfang. Данное издание не является оригинальным. Книга печатается по технологии принт-он-деманд после получения заказа.

High Quality Content by WIKIPEDIA articles! The Sea Venture was a 17th-century English sailing ship, the wrecking of which in Bermuda is widely thought to have been the inspiration for Shakespeare's The Tempest. She was the flagship of the Virginia Company, and was a highly unusual vessel for her day. The Sea Venture sat atop the reefs off Gate's Bay long enough to be stripped of all useful parts and materials, not only by her crew and passengers, but by subsequent settlers; what was left of her eventually disappeared beneath the waves. Two of her guns were salvaged in 1612 and used in the initial fortification of Bermuda (one was placed on Governor's Island, opposite Paget's Fort, the other on Castle Island). The Sea Venture was also...

The Web bears the potential to become the world's most comprehensive knowledge base. Organizing information from the Web into entity-relationship graph structures could be a first step towards unleashing this potential. In a second step, the inherent semantics of such structures would have to be exploited by expressive search techniques that go beyond today's keyword search paradigm. This work proposes a wide variety of novel search and ranking strategies over data that is organized in entity-relationship graphs. All presented techniques have been implemented as components of the NAGA search engine and published in renowned international conferences. NAGA itself is a fully implemented prototype system and is part of the YAGO-NAGA...

In order to perform a visual search for an object two capabilities must be available: the ability to recognise the object when it comes into view; and a way of selecting these views. Although visual search is often complicated by object occlusion and low spatial resolution, colour may be used as a cue since it is salient and stable under reduced resolution. This book explores the use of colour in visual search for objects in digital images at low and high spatial resolutions. The book describes the visual search process and its confounding factors, as well as reviews several colour constancy, image segmentation and object recognition algorithms from the literature. It then presents three visual search algorithms that can represent 2 or...

Searsville Dam is a masonry dam that was completed in 1892, one year after the founding of Stanford University, and impounds San Francisquito Creek to form a reservoir known as Searsville Lake. Searsville Dam is located in the Jasper Ridge Biological Preserve and is owned and operated by Stanford University. Neighboring cities include Woodside and Portola Valley, California. A vocal group argues that the dam should be removed. Searsville Dam inundated former wetlands formed by the confluence of Corte Madera Creek, Sausal Creek, Dennis Martin Creek and Alambique Creek. These wetlands likely served a valuable historical function by removing sediment and pollutants from the San Francisquito Creek...

The emergence of quad-play services (i.e., voice, video, data, and mobility) leads to a stronger integration of optical and wireless networks. The resultant bimodal fiber-wireless (FiWi) access networks aim at providing wired and wireless services over the same infrastructure simultaneously, thus potentially leading to major cost savings. Ethernet passive optical network (EPON) is a promising technology to increase the per-user bit rate for bandwidth hungry-applications in fiber-to- the-home (FTTH) networks. Similarly, next-generation WLAN supports users with mobility in wireless networks. Until now, however, security has been mostly discussed separately either in wireless or optical networks. No profound research activity has been...

A critical issue with generating pseudo-random sequences for any cryptographic application is security. One of the common techniques used to generate pseudo-random sequences has been the use of Congruential Generators (CGs). One of the well-known forms of these generators is called the Linear Congruential Generator (LCG). However these generators are known to be cryptographically weak. A highly secure pseudo-random bit sequence generation scheme (Hex-Coupled System) using coupled LCGs is proposed in this book. This book introduces other schemes of coupling CGs that generate pseudo-random sequences and two novel algorithms to generate parameters for LCGs and QCGs (Quadratic Congruential Generators). It also includes the results for the...

As the demand for higher and more sophisticated security solutions has dramatically increased, a trustworthy and a more intelligent authentication technology has to takeover. That is biometric authentication. Although biometrics provides promising solutions, it is still a pattern recognition and artificial intelligence grand challenge. More importantly, biometric data in itself are vulnerable and requires comprehensive protection that ensures their security at every stage of the authentication procedure including the processing stage. Without this protection biometric authentication cannot replace traditional authentication methods. This protection however cannot be accomplished using conventional cryptographic methods due to the nature...

Dams are among the largest and most important projects in civil engineering. About thirty-five percents of earth dams failed because seepage through and under dam bodies. In December 4, 1991, the left side embankment of west Nubaria drain at Zawiat Abdoul Kadder village, Egypt, was failed. That failure which may be returned to the blockage effect through the dam material and/or through the filter material on the seepage forces through the embankment. In this study the effect of blockage on seepage characteristics through earth dams has been studied numerically, using a finite element based model (SWICHA), and experimentally, using a viscous flow model (Hele-Shaw), for three cases of earth dams as follows: 1-Earth dam without filter,...

This book provides details of the lateral load resistance behavior of a full scale unreinforced masonry model building subjected to contained underground explosions. The explosions were designed to simulate a high amplitude short duration seismic ground motion. Test results indicate that as an alternate to expensive and small scale shake table tests, adequately designed underground explosions can be very conveniently used for testing full scale short period structures in an actual field environment. The book also provides valuable input on the seismic hazard zoning of the city of Peshawar in Pakistan, correlation between experimental and finite element based numerical model results, and the seismic performance of low rise unreinforced...

Optical methods are increasingly used for measurement of surface texture, particularly for real measurements where the optical methods are generally faster. In the evaluation of surface roughness by machine vision technique, the scattered light pattern reflected from the machined surface is generally captured and optical surface finish parameters from the images are correlated with the actual roughness. Capturing of the image at appropriate conditions is required for the good correlation of the optical parameters with the roughness. Lighting conditions is a major factor that influences the image pattern and hence the optical parameters. In this work the lighting conditions like light source angle to the workpiece, and the angle of the...

The traditional approach for thermal insulation of cold piping is specifying either vapour-impermeable insulation material and/or a continuous vapour retarder on the warm side of the insulation to minimise vapour flow to the cold surface. In theory, these materials limit the rate of water vapour ingress to a level so low that the amount of condensed water is negligible. In practice, however, this approach requires that the vapour retarding system must be continuous at all the joints, elbows, valves and fittings present in real installation. The degree of success therefore depends heavily on both the installation and the degree of maintenance provided after installation. Even with the careful installation of vapour retarders, in...

As the complexity of engineering systems is constantly increasing, their design calls for the sustainability and reliability of their high performance. Fault diagnosis (FD) is a vital system tool that addresses this critically-important issue. This book presents a clear and easy introduction to the sequential integration of the two major approaches to FD with application, namely model-free and model-based and draws on the power of the two approaches vitally for the detection of incipient faults which are hard to uncover by a single approach alone. In the model-free approach, this book explores from the intuitive approach of plausibility checks to the more sophisticated learning approaches (ANN, FL, Genetic algorithms, etc.) and their...

Substantial research efforts have been spent over the last two decades on improving the modelling, control, and design of pneumatic systems, which resulted in a potential growth for their market. This increasing acceptance for pneumatic technology is due to their economy and simplicity compared to other technologies of equivalent performance in terms of robustness, simplicity, and cost-effectiveness. However, servo-pneumatic applications are still limited compared to their electric and hydraulic counterparts. One of the restricting factors preventing wider applications of pneumatic systems arises from the highly nonlinear dynamic behaviours associated with such systems. This book, therefore, presents an overview on the modelling...
