Implementing electronic mail in a telephone system: more than just talk
Authors: Gerald Tomanek
Venue: Proceedings of the May 19-22, 1980, national computer conference (1980)

For most of us, the office of the future is a vague concept. We can see some dim shapes through the mists which look like they might be the place we want to be in a few years, but there is no obvious road from here to there. It would help to define our goal so that we can know whether or not we have arrived at the right place once we have gotten somewhere, and it would help even more to know whether or not we are getting closer to it as we move forward. Then we could pick one of the paths that seems to lead in the right direction. The ACM Portal is published by the Association for Computing Machinery. Copyright © 2010 ACM, Inc.

Fingerprint Based Temporary Identity Supporting Emergency Actions in Collective Accidents
Authors: Adina Astilean, Camelia Avram, Tiberiu Letia, Florian Mihele
Venue: Proceedings of the 2009 International Conference on eHealth, Telemedicine, and Social Medicine (2009)

The paper presents a fingerprint based identification solution, integrated with a communication system in order to support and improve the activity of emergency services on large areas, in accidents implying multiple victims. In such situations, due to possible post-accident effects, it is difficult to obtain the victims' identity data. Consequently, the occasional patients must be local-identified before to be diagnosed and sent to the appropriate hospital unit. The implemented system allows the obtaining of a provisional identity of the persons, which replaces identity cards along the whole investigation and treatment period even in the absence of any identity act. This identity may be maintained during the whole post accident evolution of a patient, in all the hospitals where a specified person was sent. The victims are registered, their data and evolution being stored and finally, directed from the temporary identity to the true identity, if the conditions allow this. The fingerprint becomes, during a shorter or a longer time interval, the equivalent of an identity card. The proposed system allows local and remote data transmission, voice communication and distributed file sharing.

The Challenges of Multicore: Information and Mis-Information
Authors: Yale Patt
Venue: Proceedings of the 22nd International Conference on Architecture of Computing Systems (2009)

Now that we have broken the threshold of one billion transistors on a chip and multi-core has become a reality, a lot of buzz has resulted --- from how/why we got here, to what is important, to how we should determine how to effectively use multicore. In this talk, I will examine a number of these new "conventional wisdom" nuggets of information to try to see whether they add value or get in the way. For example: what can we expect multicore to do about saving power consumption? is ILP dead? should sample benchmarks drive future designs? is hardware sequential? should multicore structures be simple? is abstraction a fundamental good? Hopefully, our examinations will help shed some light on where we go from here.
Peers' Segment Replacement Strategies in P2P Vod System Based On Client-Side Segmented Cache
Authors: Lei Kai, Sun Xiao, Qiao Zhigang, Peng Lingjuan, Li Hui
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 03 (2009)

In client-side segmented cache based P2P VOD system, statically cached video files in peers' disks can efficiently improve data acquisition rate. However, since disk space in a single peer is very limited, it becomes a key problem to design reasonable strategies for replacing those data segments. We start at studying the three VOD system models, and analyze the necessity of utilizing segmented storage mechanism, then focus on discussing and comparing five segment replacement strategies at client side: FIFO, LRU, LRF, EDF, and LSSF. These strategies sufficiently take local system parameters of a peer and global data distribution patterns into consideration, and manage to save high use rate, high hit rate segments in limited peers' disk space. Our experiment results indicate that, when a peer's cache size is increased from 240M to 960M, the use rate of data segments at client side rises by 36%, but the rate will rise little if continuously increasing its cache size; overall, under the same system environment, LSSF shows best performance
New strategies for gridded physical design for 32nm technologies and beyond
Authors: Stephen P. Kornachuk, Michael C. Smayling
Venue: Proceedings of the 2009 international symposium on Physical design (2009)

In this invited talk, we present a physical design solution for manufacturability in advanced technology nodes that is significantly different than existing approaches based on DFM analysis tools and rules-based restrictions. This new gridded design strategy optimizes layout efficiency, conforms to existing CAD flows, and results in improved device and interconnect formation, which in turn reduces sub-threshold leakage and electrical variability. We first review lithography and manufacturing issues common to advanced technology nodes. We also look at existing DFM strategies and rules-base physical design solutions, and the reasons these approaches are insufficient for manufacturing success in 32nm and below. As an alternate solution, we propose optimization and use of a pre-determined set of layout sub-structures, with a fixed number of allowable shape placement grids, shape dimensions, and edge to edge relationships. The result is a physical design solution for general purpose layout that can be more finely optimized for the given process capability, achieving layout density efficiency similar to that realized for memory. The gridded physical design principles also result in predictable and fixed device and interconnect contexts, regardless of cell placement. This simplifies design flows by reducing the requirement for statistical timing analysis, and enhances cell and path performance by eliminating the over-margining required to compensate for multiple possible cell contexts. Lithographic and electrical simulations highlight how post-manufacturing improvements in device variability and leakage are achieved. Test silicon measurements also show significant reductions in variability and drain-source leakage. While the primary benefits of gridded physical design relate to polysilicon for 32nm, the extensions of these strategies for diffusion, contact, and local metal layers become more important at 28nm and below.
A simulation template for modeling tunnel shaft construction
Authors: Fangyi Zhou, Simaan M. AbouRizk, Siri Fernando
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

This paper presents the design and development of a template for analyzing shaft construction projects. It is suitable for integration with the existing Tunneling template of the Simphony modeling environment to provide users a complete, functional and more flexible simulation tool for tunnel construction. The developed system will be a powerful tool for decision-making and evaluating the feasibility of tunnel construction methods, in identifying and allocating site spaces, and in the visualization of tunneling construction sites as a mean of describing the site layout to other involved parties. Further, it assists users in modeling several scenarios without changing the developer's code or the base of the tool, and it does not require integration with any other modeling templates. This template design is then applied to a case study involving the construction of a circular tunnel shaft, part of the North Edmonton Sanitary Tunneling (NEST) system in Edmonton, Canada.
Challenges in execution of outsourcing contracts
Authors: Nagesh Mukunda Rao
Venue: Proceedings of the 2nd India software engineering conference (2009)

In today's world, companies try to maximize outsourcing to stay competitive in the market. Companies worldwide acknowledge the fact that to stay ahead in competition; they need to reduce costs, deliver the best quality, use latest high-tech skills, and be reliable and creative. Going a step ahead, customers expect a transformation rather than a transition partner, meaning the service providers are expected to add value to the business while supporting the product and meeting the defined service level agreements. Transformation determines the maturity level of the service provider's organization. In the software industry, approximately 50-70% of the revenue generation with major players comes from outsourcing deals. In many cases these deals are moved from one organization to another due to mismanagement by the service providers, leading to unsatisfied customers. This paper provides the insights in to the list of common issues faced during the execution of the outsourcing deals in medium and small sized organizations and the approaches implemented towards resolving the issues.
A Business-Level Service Model Supporting End-User Customization
Authors: Jianwu Wang, Jian Yu
Venue: Service-Oriented Computing - ICSOC 2007 Workshops: ICSOC 2007, International Workshops, Vienna, Austria, September 17, 2007, Revised Selected Papers (2009)

If end users can utilize the abundant Web services to construct business applications on demand and independently, the ever changing business requirements will be met efficiently and timely. However, Web services are difficult for end users to use directly due to both the diversity of Web services and the diversity of end-user requirements. To tackle the problem, we introduce feature modeling and configuring techniques in domain engineering into service-oriented computing, and correspondingly propose a business-level service model and an end-user friendly service customization mechanism. Feasibility of the proposals is demonstrated on an example.
To search or to explore -- that is the question: a study in mindful engagement
Authors: Jon Pearce, Sofia Pardo
Venue: Proceedings of the 20th Australasian Conference on Computer-Human Interaction: Designing for Habitus and Habitat (2008)

It's easy to attract someone's attention on the web -- seductive animations using software such as Flash make this all too easy. But how do you retain their interest and, more importantly, keep their focus on the task at hand? We have approached this question by producing a research tool called iFISH that enables us to quickly construct environments in which users explore a range of outcomes based on their dynamic changes to personal preference settings, together with reflections on the consequences of these changes. We first describe a study using this tool in the context of students given the task of making a selection from a large range of university subjects, and later we introduce other uses of such a system.
Efficient Processing of Metric Skyline Queries
Authors: Lei Chen, Xiang Lian
Venue: IEEE Transactions on Knowledge and Data Engineering (2009)

Skyline query is of great importance in many applications, such as multi-criteria decision making and business planning. In particular, a skyline point is a data object in the database whose attribute vector is not dominated by that of any other objects. Previous methods to retrieve skyline points usually assume static data objects in the database (i.e. their attribute vectors are fixed), whereas several recent work focus on skyline queries with dynamic attributes. In this paper, we propose a novel variant of skyline queries, namely metric skyline, whose dynamic attributes are defined in the metric space (i.e. not limited to the Euclidean space). We illustrate an efficient and effective pruning mechanism to answer metric skyline queries through a metric index. Most importantly, we formalize the query performance of the metric skyline query in terms of the pruning power, by a cost model, in light of which we construct an optimized metric index aiming to maximize the pruning power of metric skyline queries. Extensive experiments have demonstrated the efficiency and effectiveness of our proposed pruning techniques as well as the constructed index in answering metric skyline queries.

Equalizer: a scalable parallel rendering framework
Authors: Stefan Eilemann, Maxim Makhinya, Renato Pajarola
Venue: ACM SIGGRAPH ASIA 2008 courses (2008)

Continuing improvements in CPU and GPU performances as well as increasing multi-core processor and cluster-based parallelism demand for flexible and scalable parallel rendering solutions that can exploit multipipe hardware accelerated graphics. In fact, to achieve interactive visualization, scalable rendering systems are essential to cope with the rapid growth of data sets. However, parallel rendering systems are non-trivial to develop and often only application specific implementations have been proposed. The task of developing a scalable parallel rendering framework is even more difficult if it should be generic to support various types of data and visualization applications, and at the same time work efficiently on a cluster with distributed graphics cards. In this paper we introduce a novel system called Equalizer, a toolkit for scalable parallel rendering based on OpenGL which provides an application programming interface (API) to develop scalable graphics applications for a wide range of systems ranging from large distributed visualization clusters and multi-processor multipipe graphics systems to single-processor single-pipe desktop machines. We describe the system architecture, the basic API, discuss its advantadges over previous approaches, present example configurations and usage scenarios as well as scalability results.
A System for the Fast Prototyping of Multidimensional Image Retrieval
Authors: Carlo Meghini, Fabrizio Sebastiani, Umberto Straccia
Venue: Proceedings of the 1999 IEEE International Conference on Multimedia Computing and Systems - Volume 02 (1999)

Multidimensional image retrieval (MIR) views an image as a multidimensional object, where each dimension is a channel for retrieval. MIR has the potential of putting at work together the many methods and techniques for image retrieval proposed in several different fields of computer science. We have developed a model of MIR, based on a fuzzy description logic, that identifies two main dimensions in an image (form and content) and views MIR as a special form of uncertain implication. In this paper, we present ARIANNA, a system that implements the model. ARIANNA allows to quickly develop a prototype of a MIR application, and use it to test the adequacy of the application to the user's functional requirements.

Authors: Fang Yuefeng, Wang Xiaoyong
Venue: Proceedings of the 3rd WSEAS international conference on Circuits, systems, signal and telecommunications (2009)

Water often leads rust, it can also remove rust. The paper mainly discusses the mechanism of de-rusting by ultra-high pressure (short for u.h.p.) pure water as high as 200 to 250Mpa. It adopts u.h.p rotating waterjet, automatic wall-climbing and rust dregs vac sorbing and recycling. Mechanism of water-jtetting de-rusting is to scour and strip the rusty scale of the converted steel surface by normal hitting power and edge angle of waterjet and twisting force of rotating. The testing proves the mechanism equation.
Iterative decoding algorithms for turbo product codes
Authors: Rodica Stoian, Lucian Andrei Perisoara
Venue: Proceedings of the 5th conference on Applied electromagnetics, wireless and optical communications (2007)

In this paper we introduce the iterative decoding principle, "the turbo principle", for the bidimensional Turbo Product Codes (TPC's). The constituent codes used for encoding on rows and columns are two concatenated (7,4) Hamming block codes. Several Soft Input Soft Output (SISO) algorithms can be used for the iterative decoding process. At each iteration, the two decoders decode all rows, then all columns. For particular SISO algorithms, Maximum A Posteriori (MAP) algorithm and Soft Output Viterbi Algorithm (SOVA), the system is simulated and performances, in terms of Bit Error Rate (BER), are evaluated for an AWGN channel with BPSK modulation.
A Fast Acquisition Algorithm Based on FFT for DSSS Signal and FPGA Realization
Authors: Guoliang Sun, Huang Qihua, Zhu Lisen
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 01 (2009)

Traditional methods have some defects for DSSS signal acquisition, large quantities of calculation, high source occupation, worse dynamic performance, etc. As these taken into account, an fast acquisition algorithm based on FFT was put forward. In this method, multiple correlators were used to search code phase in the same time and a FFT function was shared to find the carrier Doppler frequency. As the frequency search eliminated from the acquisition process, the acquisition speed was increased and dynamic performance was improved. The principle of this method was described in detail. CycloneII EP2C70 FPGA of Altera Company was used to realize and verify the acquisition method. Key parameters design was given. The results of test show that it has a high speed of acquisition while saving the hardware resources.
ATL with Strategy Contexts and Bounded Memory
Authors: Thomas Brihaye, Arnaud Costa, François Laroussinie, Nicolas Markey
Venue: Proceedings of the 2009 International Symposium on Logical Foundations of Computer Science (2009)

We extend the alternating-time temporal logics ATL and ATL* with strategy contexts and memory constraints: the first extension makes strategy quantifiers to not "forget" the strategies being executed by the other players. The second extension allows strategy quantifiers to restrict to memoryless or bounded-memory strategies.We first consider expressiveness issues. We show that our logics can express important properties such as equilibria, and we formally compare them with other similar formalisms (ATL, ATL*, Game Logic, Strategy Logic, ...). We then address the problem of model-checking for our logics, especially we provide a PSPACE algorithm for the sublogics involving only memoryless strategies and an EXPSPACE algorithm for the bounded-memory case.

The forecasting model based on wavelet ν-support vector machine
Authors: Qi Wu
Venue: Expert Systems with Applications: An International Journal (2009)

Aiming at the series with small samples, seasonal character, nonlinearity, randomicity and fuzziness, the existing support vector kernel does not approach the random curve of the sales time series in the L^2(R^n) space (quadratic continuous integral space). A new wavelet support vector machine (WN @n-SVM) is proposed based on wavelet theory and modified support vector machine. A particle swarm optimization (PSO) algorithm is designed to select the best parameters of WN @n-SVM model in the scope of constraint permission. The results of application in car sale series forecasting show that the forecasting approach based on the PSOWN @n-SVM model is effective and feasible, the comparison between the method proposed in this paper and other ones is also given which proves this method is better than PSOW @n-SVM and other traditional methods.
Improving Broadcast News Segmentation Processing
Authors: Stanley Boykin, Andrew Merlino
Venue: Proceedings of the IEEE International Conference on Multimedia Computing and Systems - Volume 2 (1999)

This document discusses techniques and results for automatically segmenting multimedia sources, with specific emphasis on broadcast news. In this paper we describe techniques that detect news events (e.g., start and stop of stories or advertisements) using simple cues within and across multimedia streams (e.g., audio, video, text). In addition, we discuss a process for an evaluation and modification of our model using precision and recall metrics. Guided by our findings, we isolate multimedia cues that we consider critical in news story and advertisement segmentation. We also discuss ideas for improving segmentation beyond the methods described. Throughout the paper, we reference MITRE's Broadcast News Navigator (BNN) used to perform event segmentation.
Graphical Modelling for Simulation and Formal Analysis of Wireless Network Protocols
Authors: A. Fehnker, M. Fruth, A. K. Mciver
Venue: Methods, Models and Tools for Fault Tolerance (2009)

It is well-known that the performance of wireless protocols depends on the quality of the wireless links, which in turn is affected by the network topology. The aim of this paper is to investigate the use of probabilistic model checking in the analysis of performance of wireless protocols, using a probabilistic abstraction of wireless unreliability.Our main contributions are first, to show how to formalise wireless link unreliability via probabilistic behaviour derived from the current best analytic models [12], and second, to show how such formal models can be generated automatically from a graphical representation of the network, and analysed with the PRISM model checker.We also introduce CaVi, a graphical specification tool, which reduces the specification task to the design of the network layout, and provides a uniform design interface linking model checking with simulation. We illustrate our techniques with a randomised gossiping protocol.
