=1.3,Like Section 3.3.7,CT Like Section 3.3.8,CDD Like Section 3.3.9,C N Like Section 3.3.10.3.4C o s t G r o u p II: B a s i cMoldsThe basic mold retains the cavities, the basic functional components (runner, heatexchange and ejector system) and any necessary special functional elements (three-platemold, slides, unscrewing unit). As far as self-made basic molds are concerned, it ispractical to distinguish different quality grades.A basic mold of grade I is for a small number of moldings with little precision, for testseries etc. It is not hardened.A basic mold grade II has case-hardened plates, additional alignment, heat insulationon the stationary half and, if of round design, is equipped with three leader pins. It isassumed to produce technical parts and medium-sized quantities.A basic mold grade III is largely hardened and made with large quantities, highprecision and reliability in mind [3.7].However, injection molds are largely built with mold standards. Thus the total costsof the basic mold are primarily the costs for the readily usable standards, expenses forspecific machining operations not included (Figure 3.8). It is suggested, though, toconsult the catalogs of suppliers for up-to-date prices and the availability of mold basesof a different design like such with floating plates, etc.Standard basic molds are all of the highest quality and differ only in the steel gradebeing employed, which affects the service life of the mold, its polishability or its

Tiêu chuẩn Châu Âu EC3: Kết cấu thép phần 4.3: Ống dẫn (Eurocode3 BS EN1993 4 3 e 2007 Design of steel structures part 4.3: Pipeline)

(1) This Part 43 of EN 1993 provides principles and application rules for the structural design of cylindrical steel pipelines for the transport of liquids or gases or mixtures of liquids and gases at ambient temperatures, which are not treated by other European standards covering particular applications. (2) Standards dealing with specific pipeline applications should be used for these purposes, notably EN 805 : 2000 for water supply systems (drinking water); EN 1295: 1997 for buried pipelines under various conditions of loading (waste water); EN 1594: 2000 for gas supply systems for operating pressures over 16 bar; EN 12007: 2000 for gas supply systems up to and including 16 bar; EN 12732: 2000 for welding; EN 13941: 2003 for preinsulated bonded pipe systems for district heating; EN 13480: 2002 for industrial pipelines; EN 14161: 2004 for pipeline transportation systems for the petroleum and natural gas industries. (3) Rules related to special requirements of seismic design are provided in EN 19984 (Eurocode 8: Part 4 Design of structures for earthquake resistance: Silos, tanks and pipelines), which complements the rules of Eurocode 3 specifically for this purpose. (4) This Standard is restricted to buried pipelines, corresponding to the scope of Eurocode 8 Part 4 for pipelines. It is specifically intended for use on: Buried pipelines in settlement areas and in nonsettlement areas; Buried pipelines crossing dykes, traffic roads and railways and canals. (5) The design of pipelines involves many different aspects. Examples are routing, pressure safety systems, corrosion protection, construction and welding, operation and maintenance. For aspects other than the structural design of the pipeline itself, reference is made to the relevant European standards listed in 1.2. This is also the case for elements like valves, fittings, insulating couplings, tees and caps. (6) Pipelines usually comprise several associated facilities such as pumping stations, operation centres, maintenance stations, etc., each of them housing different sorts of mechanical and electrical equipment. Since these facilities have a considerable influence on the continued operation of the system, it is necessary to give them adequate consideration in the design process aimed at satisfying the overall reliability requirements. However, explicit treatment of these facilities, is not included within the scope of this Standard. (7) Although large diameter pipelines are within the scope of this Standard, the corresponding design criteria should not be used for apparently similar facilities like railway tunnels and large underground gas reservoirs. (8) The provisions in this Standard are not necessarily complete for particular applications. Where this is the case, additional provisions specific to those applications should be adopted. (9) This Standard specifies the requirements regarding material properties of plates and welds in terms of strength and ductility. For detailed guidelines and requirements about materials and welding, reference should be made to the relevant standards listed in 1.2. `,,`,`,``,,,,`,`,```,```,`````,,`,,`,`,,`

An Internetbased system also allows process planners in anyindustry to react to any unanticipated changes. Tosupport the data exchange between different systemsused at different virtual enterprise companies, thecombination of the Internet and STEP provides anattractive solution. However, there are still somesetbacks in the current systems, such as too large datapackage to be transferred and lack of methods that canmanage cooperative control commands more efficiently.STEP helps to solve the problem of sharinginformation between different applications and software that arise from the incompatibility of productdata representations (Kramer et al. 2006). Because ofits neutral product data format, use of STEP in CAPPleads to the possibility of using standard datathroughout the entire product process chain in themanufacturing environment, hence increases the system’s capability of integrating with other systems in theentire CIM environment.

[FULL] Cooperative communications and networking by K.J.Ray liu, Ahmed K.Sadek, Weifeng Su and Andres Kwasinski

[FULL] COOPERATIVE COMMUNICATIONS AND NETWORKING BY K.J.RAY LIU, AHMED K.SADEK, WEIFENG SU AND ANDRES KWASINSKI

The main goals of this textbook are to introduce the concepts of space, time,frequency diversity, and MIMO techniques that form the foundation of cooperativecommunications, to present the basic principles of cooperative communicationsand networking, and to cover a broad range of fundamental topics where significantimprovements can be obtained by use of cooperative communications. The bookincludes three main parts:• Part I: Background and MIMO systems In this part, the focus is on buildingthe foundation of MIMO concepts that will be used extensively in cooperative communicationsand networking. Chapter 1 reviews of fundamental material on wirelesscommunications to be used in the rest of the book. Chapter 2 introduces the conceptof space–time diversity and the development of space–time coding, includingcyclic codes, orthogonal codes, unitary codes, and diagonal codes. The last chapter inthis part, Chapter 3, concerns the maximum achievable space–time–frequency diversityavailable in broadband wireless communications and the design of broadbandspace–frequency and space–time–frequency codes.• Part II: Cooperative communications This part considers mostly the physicallayer issues of cooperative communications to illustrate the differences and improvementsunder the cooperative paradigm. Chapter 4 introduces the concepts of relaychannels and various relay protocols and schemes. A hierarchical scheme that canachieve linear capacity scaling is also considered to give the fundamental reasonPreface xiiifor the adoption of cooperation. Chapter 5 studies the basic issues of cooperationin the physical layer with a single relay, including symbol error rate analysis fordecodeandforward and amplyandforward protocols, performance upper bounds,and optimum power control. Chapter 6 analyses multinode scenarios. Chapter 7presents distributed space–time and space–frequency coding, a concept similar tothe conventional space–time and space–frequency coding but different in that it isnow in a distributed setting where assumptions and conditions vary significantly.Chapter 8 concerns the issue of minimizing the inherent bandwidth loss of cooperativecommunications by considering when to cooperate and whom to cooperatewith. The main issue is on devising a scheme for relay selection and maximizing thecode rate for cooperative communications while maintaining significant performanceimprovement. Chapter 9 develops differential schemes for cooperative communicationsto reduce transceiver complexity. Finally, Chapter 10 studies the issues ofenergy efficiency in cooperative communications by taking into account the practicaltransmission, processing, and receiving power consumption and illustrates the tradeoffbetween the gains in the transmit power and the losses due to the receive andprocessing powers when applying cooperation.• Part III: Cooperative networking This part presents impacts of cooperative communicationsbeyond physical layer, including MAC, networking, and applicationlayers. Chapter 11 considers the effect of cooperation on the capacity and stabilityregion improvement for multiple access. Chapter 12 studies how special properties inspeech content can be leveraged to efficiently assign resources for cooperation andfurther improve the network performance. Chapter 13 discusses cooperative routingwith cooperation as an option. Chapter 14 develops the concept of source–channel–cooperation to consider the tradeoff of source coding, channel coding, and diversityfor multimedia content. Chapter 15 focuses on studying how source coding diversityand channel coding diversity interact with cooperative diversity, and the systembehavior is characterized and compared in terms of the asymptotic performance of thedistortion exponent. Chapter 16 presents the coverage area expansion with the helpof cooperation. Chapter 17 considers the various effects of cooperation on OFDMbroadband wireless communications. Finally, Chapter 18 discusses network lifetimemaximization via the leverage of cooperation.This textbook primarily targets courses in the general field of cooperative communicationsand networking where readers have a basic background in digital communicationsand wireless networking. An instructor could select Chapters 1, 2, 4, 5, 6, 7.1, 8,10, 11, 13, 14, and 16 to form the core of the material, making use of the other chaptersdepending on the focus of the course.It can also be used for courses on wireless communications that partially cover thebasic concepts of MIMO andor cooperative communications which can be consideredas generalized MIMO scenarios. A possible syllabus may include selective chaptersfrom Parts I and II. If it is a course on wireless networking, then material can be drawnfrom Chapter 4 and the chapters in Part III.xivPrefaceThis book comes with presentation slides for each chapter to aid instructors with thepreparation of classes. A solution manual is also available to instructors upon request.Both can be obtained from the publisher via the proper channels.This book could not have been made possible without the contributions of the followingpeople: Amr ElSherif, T. Kee Himsoon, Ahmed Ibrahim, Zoltan Safar, KarimSeddik, and W. Pam Siriwongpairat. We also would like to thank them for their technicalassistance during the preparation of this book.

17M o l dS t a n d a r d sInjection molds are always made in accordance with the same rules. Therefore, it shouldnot come as a surprise that their design approach is always similar. This holdsparticularly true for the basic components. A great number of companies are specializedin manufacturing such basic elements. They produce these elements on a large scale andin a variety that a detailed discussion of these products would be beyond the scope of thischapter. We emphasize, therefore, to contact a supplier of mold standards. Suppliers offerextensive and very informative catalogs. Sometimes the information is also available asa software database. Figures 17.1-17.3 and Table 17.1 show the most common moldstandards and their application areas.Mold standards are parts or modules whose dimensions have been standardized andcharacterized. In line with the basic design of a mold, they can be classified as standardsfor the mold structure, the cavity, the gate system, the guides and centering, for heatcontrol, for demolding and for accommodating the mold in the injection moldingmachine.The use of mold standards shortens production times and relieves the designer andmold maker of routine work. Advantages are:- For computer-assisted design, standards can be retrieved from a database, displayed onthe screen and employed in the design ("features"). The user has the option to "play"with several variants to select the solution which is the most suitable one in hisopinion. This relieves him of routine work.- The uncertainty in a quotation is smaller because one can calculate with fixed costs forthe individual elements.- Work input into the production of the molds can be reduced by 25-45% through theuse of standards. Extensive studies have shown that 55% of the total work is performedby the mold maker himself, 25% by the standards producer, and 20% can additionally

AUTOMATICALLY CREATING MULTILINGUAL LEXICAL RESOURCES

English, Spanish and Japanese), to be resource-rich in relative terms; researchers havecreated many resources to facilitate various aspects of computational processing for suchlanguages. There are a few other languages that have a limited number of resources, butcan benefit from additional resources (e.g., Arabic and Vietnamese). Other languages havevery few resources, if any. Many other languages are becoming endangered, a state whichis likely to lead to their extinction, without determined intervention. Some endangeredlanguages are Chrau and Tai Daeng in Vietnam, Karbi and Dimasa in India, Cherokee andCheyenne in America.We construct lexical resources necessary for computational processing of natural languages in areas such as information retrieval, automatic word-sense disambiguation, computing document similarity, machine learning, and machine translation. Consider bilingualdictionaries, an essential tool for human language learners. Most existing (print or online) bilingual dictionaries are between two resource-rich languages (e.g., English-Spanish,Japanese-Chinese and French-German dictionaries), or between a resource-rich languageand a resource-poor language (e.g., English-Assamese and English-Cherokee dictionaries).The powerful online machine translators (MT) developed by Google6 and Bing7 providepairwise translations for 80 and 50 languages, respectively. These machines provide translations for single words and phrases also. In spite of so much information for some “privileged”language pairs, there are many languages for which we are lucky to find a single bilingualdictionary online or in print. For example, we can find an online Karbi-English dictionaryand an English-Vietnamese dictionary, but we can not find a Karbi-Vietnamese dictionary.Another important resource that is very helpful in computational processing and in humanlanguage learning is a thesaurus providing synonyms and antonyms of words.
