since the end of Dennard scaling in the early 2000s, improving the energy efficiency of computation has been the main concern of the research community and industry. The large energy efficiency gap between general-purpose processors and application-specific integrated circuits (AsICs) motivates the exploration of customizable architectures, where one can adapt the architecture to the workload. In this synthesis lecture, we present an overview and introduction of the recent developments on energy-efficient customizable architectures, including customizable cores and accelerators, on-chip memory customization, and interconnect optimization. In addition to a discussion of the general techniques and classification of different approaches used in each area, we also highlight and illustrate some of the most successful design examples in each category and discuss their impact on performance and energy efficiency. We hope that this work captures the state-of-the-art research and development on customizable architectures and serves as a useful reference b.s.s for further research, design, and implementation for large-scale deployment in future computing systems.

system management is the task of installing, administering, and maintaining a communications system. Customer and technician access to software-b.s.d administration and maintenance capabilities in the system 75 office communication system occurs through an on-line video display terminal called the system Access Terminal (sAT). With the sAT, the user may install, test, rearrange, and change equipment and services. The sAT hides the internal complexity of the system while presenting all the capabilities in as simple a manner as possible. A layered software architecture is used to perform data view mapping from the user view to the internal data representation.

Creating digital content and distributing them has become much easier and convenient nowadays, where the digital content creator can create the content and also distribute their work to others from anywhere with the help of internet. This also has the risk as the content is distributed using internet, the risk being copyright infringement and illegal distribution of the content. To avoid these types of risks the content creators are opting towards the help of digital rights management. The digital rights management team provides help and support to the content creators in cases where their work is illegally copied or distributed. To get the digital content copyrighted is also not an easy task as it consumes time and money. The proposed model overcomes these issues by integrating digital signature, structure similarity index measurement (ssIM) and blockchain technology in the digital rights management life cycle. The digital signature is used to uniquely identify the user and the related information can be traced back to the user using digital signature, and the copyright is provided using the ssIM method. The ssIM value can be in the range of -1 to 1 where 1 denotes that both the media files are identical and the system updates this information so that all the participant can view this information. If the ssIM value after comparing both the media files is -1 then the both images are unique and authentic, then the copyright is provided for the media file and this information is updated in the system as well as Ethereum blockchain. This makes the system more secure, rob.s. and transparent.

Columb.s.fans performance degradation has been monitored for more than two years. Different activities were performed in 2010-2011 timeframe in order to mitigate dust accumulation in the air loop. Inter-Module Ventilation (IMV) Return Fan Assembly (IRFA) has been kept switched off since the end of 2009 (save for testing and/or on National Aeronautic and space Administration (NAsA) request);Return Grid sensor Housing (RGsH) internal cleaning frequency was increased from one year to three months;an additional grid has been installed over RGsH. Finally, while the effectiveness of the Add-On Return Grid (AORG) is being certified after a testing of ten months, an Inspection & Cleaning (I&C) of the ventilation ducts, Cabin Fan Assemblies (CFAs) internal and relevant debris screen was performed at the end of February 2012. In parallel, an Air Loop test campaign was conducted to define new temporary working points, in order to gain fully stable performances in selected scenarios. The paper documents the methodology of fan performance monitoring (via telemetryderived parameters), the effects/results of above mentioned activities on the fans performances and the activities of the fans/air loop I&C. © 2012 by the American Institute of Aeronautics and Astronautics, Inc.

In this paper we present results of a series of experiments in which combinations of vector quantization and temporal energy contours are incorporated into the standard framework for the word recognizer. We consider two distinct word vocabularies, namely, a set of 10 digits, and a 129-word airlines vocabulary. We show that the incorporation of energy leads to small but consistent improvements in performance for the digits vocabulary; the incorporation of vector quantization (in a judicious manner) leads to small degradation in performance for both vocabularies, but at the same time reduces overall computation of the recognizer by a significant amount. We conclude that a high-performance, moderate-computation, isolated word recognizer can be achieved using vector quantization and the temporal energy contour.

A novel approach for cross language information retrieval

A novel approach for cross language information retrieval

引用

International Conference on Electronic computer Technology

作者： b. Manikandan R. shriram Department of Computer Science and Engineering B.S. Abdur Rahman University Chennai India

Cross-language information retrieval (CLIR) is a subfield of information retrieval dealing with retrieving information written in a language different from the language of the user's query. The domain of CLIR is crucial in the future as vast amount of content in the web is in English. There is a need for mechanisms that can retrieve the content from English and translate it to the native language. This paper proposes a text summarization-suffix tree algorithm for the overall process of CLIR. The idea is to summarize the content and re-rank the results b.s.d on clustered coefficients. This method can improve the efficiency of the content retrieved and afford a great flexibility to the user. The key contributions of this paper are to explain the approach and discuss the key results.

This paper describ.s.a method of precisely and effectively visualizing a complex 3-dimensionally curved surface from a set of range data by using meshes (parallel hierarchical triangulation) which are adaptive to the degree of its complexity. The method can reconstruct the curved surface without cracks by approximating its intrinsic shape and discontinuity with a polygon. The algorithm used can be processed by fast parallel local calculations with an upper limit in time and space. This paper proposes a parallel recursive algorithm for generating an adaptive mesh using a 3D-curvature b.s.d on the intrinsic shape of an object, and another parallel recursive algorithm to avoid the formation of a crack which occurs between two subdivisions. Experimental results applied to range images of human faces are shown. The proposed method can be applied to general images (e.g., gray-level image and color images) other than range images so that the compression or reconstruction of an image can be carried out by adaptively using its geometrical features (e.g., the pixel value, its first-order differential, and second order differential).

In recent years, vehicular networks have gained much attention in industry as well as academia. Most of the research in this area is simulation b.s.d. The determination of the performance of protocols in Vehicular Ad Hoc Networks (VANETs) is achieved by mobility models, or the movement patterns of nodes communicating wirelessly which play a vital role in simulation. It is essential to study and analyze various mobility models and its performance in VANET protocols. In this paper, we propose a Dynamic Transition Mobility Model (DTMM) and it is compared, analyzed and thoroughly examined with various mobility models. Also, evaluate its effect on packet delivery in VANETs carried out in NCTUns5.0 simulations. This paper gives an opportunity to understand and develop mobility models for VANETs. © 2012 binary Information Press January 2012.

Automatic speech recognition has advanced to the stage where it is now possible to recognize connected strings of words (e.g., digits, letters, city names, airline terms) from a word reference set of isolated tokens of each of the words in the vocabulary. Recently, an improved training technique called embedded word training was proposed, in which reference word patterns were extracted from within connected word sequences themselves. In this investigation we extend the embedded word training procedure to handle letters of the alphabet for use in a directory listing retrieval task. by performing connected letter recognition of spoken names b.s.d on letter classes (rather than specific letters themselves), we show how reliable name recognition results can be achieved using a fairly straightforward system on 200 randomly chosen names (chosen from an 18,210-name directory) spoken at a normal rate by four talkers (three male, one female) in a speaker-trained mode. We have found that an 8-percent improvement in name recognition accuracy is obtained when using embedded letter training patterns over that obtained from isolated letter patterns alone. The overall name recognition accuracy was close to 95 percent.

A METHODOLOGY FOR sETTING COMbAT system REQUIREMENTs

引用

NAVAL ENGINEERs JOURNAL 1985年第4期97卷 274-278页

作者： MENsH, DR The Author received his B.S. and M.S. degrees in applied physics from Loyola College in Baltimore Md. and the American University in Washington D.C. He also has completed his course work towards his Ph.D. degree in computer science specializing in the fields of system analysis and computer simulation. He has been employed at the Naval Surface Weapons Center White Oak Laboratory Silver Spring Md. for the past eighteen years in the areas of weapon system analysis and the development of weapon system simulations. Since 1978 he has been involved in the development of simulation tools that can be applied to the solution of shipboard combat system architecture and engineering problems. Currently at the White Oak Laboratory he is responsible for the application of and further development of the single ship combat system simulation.

This paper describ.s.a methodology for setting combat system requirements for all ship classes. The requirements are determined from a battle group perspective. The methodology uses ship damage as a measure of effectiveness for setting combat system requirements. The ship damage data used was derived from the Navy tactical game (NAVTAG). The methodology that determines ship class combat system requirements consists of a set of logical steps that are iterative by design. It provides insight and valid estimates of numerical measures of defined force requirements at several levels. This process is not trivial; the expected level of effort could be significant. The method consists of five b.s.c stages considered necessary to achieve valid results. These stages are (1) determination of force level requirements, (2) determination of force level capability, (3) analysis of force level capability, (4) determination of class requirements by battle overviews, and (5) determination of class requirements — overall. The methodology was used by the combat system master plan (CsMP) manager for determining top level combat system requirements for individual platforms in a battle group. In addition, once levels of combat system performance have been defined, this methodology generates a quantitative data b.s. that becomes a useful tool in ship combat suite selection. Once alternate combat system suites have been defined, these suites can be analyzed in terms of combat system performance capability versus cost.
