Authors: Yuchun Sun, Peijun Lü, Yong Wang
Venue: Computer Methods and Programs in Biomedicine (2009)

This study explored a method for fabricating removable complete denture aided by CAD&RP technology. 3D crossing section scanner and laser scanner were respectively applied to obtain the surface data of artificial teeth, edentulous models and rims made in clinic. The vertical and horizontal relations of models were recorded before scanning with a special device. A 3D graphic database of artificial teeth, which can be aligned with parameters, was established. Special CAD software developed by ourselves was applied to the 3D integrated design process including automatic setting up artificial teeth, semiautomatic designing aesthetic and individualized artificial gingiva and base plate, automatic constructing individualized virtual flasks according to the finished CAD digital models of removable complete denture. At last, 3DP technology was used to make the individualized physical flasks. In this study, AMT and classic denture materials were effectually combined to achieve making removable complete denture aided by CAD/RP technology.
Design of Non-Critical Path Resource Distributor for SMT Processors
Authors: Hongzhou Chen, Lingdi Ping, Xiaoping Chen, Kuijun Lu
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 02 (2009)

The performance in simultaneous multithreading (SMT) processors is mainly determined by the distribution of the common resources among the threads. However, resource distribution methods often take cycles to calculate a resource allocation solution. Implementing a many-cycles resource distributor in the critical pipeline path will result in an innegligible impact on SMT processor performance. This work proposes a design of non-critical path resource distributor (NCPRD) for SMT processors, which separates the resource distribution from the critical pipeline path to avoid the clock wastage caused by the computation on the allocation solution. Our limit case study shows that, NCPRD benefits from its asynchronous work mode under both throughput and fairness metric in all type workloads but the memory-intensive workloads, and obtains more gains over the critical-path-involved resource distributor when the computation on the allocation solution spends more cycles.
Improving Disease Early Detection and Prevention by Multiplex Longitudinal Outcomes Marker Modeling
Authors: Edward C. Conley, David R. Owens
Venue: Proceedings of the 2009 International Conference on eHealth, Telemedicine, and Social Medicine (2009)

We are interested in understanding how high quality information management systems can improve disease prevention and screening services, particularly in the prevention of diabetes and its complications. As part of this effort, we are exploiting standards-driven distributed data collation, processing and computational technologies to deduce comparative performance of disease outcomes markers. In the system design, data is sent to an individualized risk management information service (e.g. as part of a home or mobile-based telehealth service). Data originating across the 'patient path' is quality controlled to improve the accuracy of risk models. Delivery of these functions 'at scale' requires the development of new data trend management and decision support tools. Semantic standardization, particularly in representation of disease progression features for data aggregation and distributed search is a key requirement. We discuss some of the current challenges surrounding outcomes marker modeling to support disease prevention and screening services.

Applications of UV-nanoimprint soft stamps in fabrication of single-frequency diode lasers
Authors: Jukka Viheriälä, Juha Tommila, Tomi Leinonen, Mihail Dumitrescu, Lauri Toikkanen, Tapio Niemi, Markus Pessa
Venue: Microelectronic Engineering (2009)

We show how to use a modified poly-dimethyl-siloxane (PDMS) soft stamp to reduce pattern deformation and residual layer thickness in soft UV-nanoimprint lithography. A soft stamp thinned with toluene reduces the residual layer of a resist by as much as 50% compared to an unthinned stamp. We apply the soft UV-nanoimprint to prepare nanopatterned waveguides for a single-frequency diode laser. This laser operates with a side-mode suppression ratio of 50dB, which indicates that the patterns are precise and uniform over the whole imprint field. To the best of our knowledge, this is the first single-frequency laser fabricated by soft UV-nanoimprint technology.
A Mathematical Model of Interference between RFID and Bluetooth in Fading Channel
Authors: Junjie Chen, Jianqiu Zeng, Yuchen Zhou
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 01 (2009)

The performance of Bluetooth under the interference of RFID is investigated. A mathematical model is proposed to quantify the performance degradation of Bluetooth. The proposed model carefully takes PHY (i.e., the channel model, the transmitted power, the distance and the modulation) and MAC (i.e., the frequency hopping, the packet format and the traffic load) into account. Packet Error Rate (PER), the average delay and the throughput are selected as the performance metrics and are analyzed in this paper. In final, the theoretical analysis is justified by the simulation.
Of social television comes home: a field study of communication choices and practices in tv-based text and voice chat
Authors: Elaine M. Huang, Gunnar Harboe, Joe Tullio, Ashley Novak, Noel Massey, Crysta J. Metcalf, Guy Romano
Venue: Proceedings of the 27th international conference on Human factors in computing systems (2009)

Social television applications have emerged as a potentially valuable convergence of media and communication, but questions remain about the utility and nature of the communication experiences they will provide. We present our study of STV3, an application that adds freeform text and voice chat capabilities to the conventional television-viewing experience. We conducted an in-depth field study of STV3 to understand how friends integrate communication through social television into their lives. Our results reveal users' choices of communication modality, their topics of conversation, and the sense of connectedness that was fostered through their use of STV3. Our findings indicate that participants overwhelmingly preferred text chat to voice chat, and that they often communicated about topics unrelated to the television content.

Authors: Davor Delač, Zoran Krleža, Jan Šnajder, Bojana Dalbelo Bašić, Frane Šarić
Venue: Proceedings of the 10th International Conference on Computational Linguistics and Intelligent Text Processing (2009)

Collocations --- word combinations occurring together more often than by chance --- have a wide range of NLP applications. Many approaches for automating collocation extraction based on lexical association measures have been proposed in the literature. This paper presents TermeX --- a tool for efficient extraction of collocations based on a variety of association measures. TermeX implements POS filtering and lemmatization, and is capable of extracting collocations up to length four. We address trade-offs between high memory consumption and processing speed and propose an efficient implementation. Our implementation allows for processing time linear to corpus size and memory consumption linear to the number of word types.

Aspect mining meets rule-based refactoring
Authors: Santiago Vidal, Esteban S. Abait, Claudia Marcos, Sandra Casas, J. Andrés Díaz Pace
Venue: Proceedings of the 1st workshop on Linking aspect technology and evolution (2009)

Aspect-oriented software development allows the encapsulation of crosscutting concerns, achieving a better system modularization and, therefore, improving its maintenance. One important challenge is how to evolve an object-oriented system into an aspect-oriented one in such a way the system structure gets gradually improved. This paper describes a process to assist developers in the refactoring of object-oriented systems to aspects. To do so, we propose a tool approach that combines aspect mining techniques with a rule-base engine to apply refactorings.
Teaching client-driven software development
Authors: Allen B. Tucker
Venue: Journal of Computing Sciences in Colleges (2009)

To teach the principles and practice of software development, there's no better motivator than a team project that can be completed in a semester, real-world clients will value, and other courses and clients can freely adapt. This paper considers a model for teaching software development that uses modern collaboration tools, open source, continuous client involvement, and teamwork as primary ingredients. The model is based on an extraordinary software development experience that occurred in Spring 2008. This paper describes that experience and suggests guidelines that enable similar courses to be taught in the future.
LCN: a loosely coupled network system
Authors: Lowell H. Schiebe
Venue: Proceedings of the May 19-22, 1980, national computer conference (1980)

The Control Data Loosely Coupled Network (LCN) system is a set of hardware and software that interconnects computers and peripheral devices and provides them a means to communicate with each other over shared high-speed data trunks. The term Loosely Coupled is used to denote that there is no master/slave relationship in the LCN system. To effect communications between two units connected to LCN both units must agree to the transaction. This type of loosely coupled connection has been described previously.
An adaptive link adaptation scheme for multi-rate wireless LANs
Authors: Youngjae Kim, Jungjoon Kim
Venue: Proceedings of the 5th conference on Applied electromagnetics, wireless and optical communications (2007)

In this paper, we propose an efficient rate switching scheme for IEEE 802.11 Wireless LANs. The proposed scheme switches the transmission rate by the patterns of transmission successes and failures, and the measured signal strength of a recently received packet. Our simulation study shows that the proposed scheme shows better performance than existing rate adaptation schemes.

Automatic Web Page Classification Using Various Features
Authors: Hao Wen, Liping Fang, Ling Guan
Venue: Proceedings of the 9th Pacific Rim Conference on Multimedia: Advances in Multimedia Information Processing (2008)

A model of automatically classifying uncertain Web pages using multiple features is presented. Since the traditional tree structure can barely classify an avalanche of new Web pages, the proposed approach partially uses the idea of "bag of words" incorporating the idea of classification fusion to describe and categorize Web pages. The proposed approach extracts features of Web pages from various perspectives, such as consulting a Web directory service, analyzing the text features of Web pages' titles and meta-search keywords, and identifying primary content of Web pages. Through fusing the results from these three dedicated classifiers, Web pages are classified to one or more categories with a bunch of words representing the Web pages. In order to demonstrate the effectiveness of the proposed method, experiments are carried out. In the experiments, the Web pages are classified using the proposed fusion method to four categories. A comparison between the dedicated classifiers and fusion methods is also presented.

Venue: Gesture-Based Human-Computer Interaction and Simulation: 7th International Gesture Workshop, GW 2007, Lisbon, Portugal, May 23-25, 2007, Revised Selected Papers (2009)

Large displays are highly suited to support discussions in empirical science. Such displays can display project results on a large digital surface to feed the discussion. This paper describes our approach to closely involve multidisciplinary omics scientists in the design of an intuitive display control through hand gestures. This interface is based upon a gesture repertoire. This paper describes how this repertoire is designed based on observations of, and scripted task experiments with, omics scientists.

Venue: Proceedings of the 2009 International Conference on Advanced Computer Control (2009)

The paper considers the application of Robust Optimization (RO) technique to model predictive control (MPC). Robust Optimization has received considerable attention recently as a result of the well accepted and proven interior-point method. The robust optimization has been investigated and applied to various application areas. It is of interest to see the application of robust optimization method in control systems. The paper shows the robust optimization is directly applicable to MPC which relies on optimization as the workhorse to compute the control signal.
Community information centres---enabling e-governance in India: lessons learnt
Authors: Shefali S. Dash, Nandita Chaudhri
Venue: Proceedings of the 2nd International Conference on Theory and Practice of Electronic Governance (2008)

Geographic remoteness and difficult hilly terrain has made the North Eastern (NE) states of India less developed. In order to bring this region to the main stream, the Government of India in 2002 set up 555 Community Information Centres (CICs) at the block level. The CICs provide digital communication including e-governance services. After five years of operation, the CICs are in the process of merging with Common Services Centres (CSCs). The CSCs scheme entails public-private partnership and the available services go beyond e-governance to commercial services like bill payment etc. After merging with CSCs, the yeoman service being done by CICs for the local community would be continued. The project demonstrates that ICT can play a major catalytic role in socio-economic development as well as empowerment of people at the grass root level.
The generating of the cutting-covering receipts using Euclid's algorithm
Authors: Iacob Paul, Marinescu Daniela, Baicoianu Alexandra
Venue: Proceedings of the 12th WSEAS international conference on Computers (2008)

We are dealing with a cutting-covering problem defined by us in [4, 5, 6]. We try to model a practical problem, to cover a rectangular room with a material. This material is in a roll of fixed width. We want to cover the room with a minimum number of pieces and to waste a minimum amount of material. In the papers [4, 5, 7, 8] we gave the cutting and covering algorithms with a high complexity. In this paper we improve the complexity by a Greedy variant. The proof of the algorithm's complexity is based on Euclid's algorithm and Lamé's theorem.
Sequenced spatio-temporal aggregation in road networks
Authors: Igor Timko, Michael H. Böhlen, Johann Gamper
Venue: Proceedings of the 12th International Conference on Extending Database Technology: Advances in Database Technology (2009)

Many applications of spatio-temporal databases require support for sequenced spatio-temporal (SST) aggregation, e. g., when analyzing traffic density in a city. Conceptually, an SST aggregation produces one aggregate value for each point in time and space. This paper is the first to propose a method to efficiently evaluate SST aggregation queries for the COUNT, SUM, and AVG aggregation functions. Based on a discrete time model and a discrete, 1.5 dimensional space model that represents a road network, we generalize the concept of (temporal) constant intervals towards constant rectangles that represent maximal rectangles in the space-time domain over which the aggregation result is constant. We propose a new data structure, termed SST-tree, which extends the Balanced Tree for one-dimensional temporal aggregation towards the support for two-dimensional, spatio-temporal aggregation. The main feature of the Balanced Tree to store constant intervals in a compact way by using two counters is extended towards a compact representation of constant rectangles in the space-time domain. We propose and evaluate two variants of the SST-tree. The SSTT-tree and SSTH-tree use trees and hashmaps to manage spacestamps, respectively. Our experiments show that both solutions outperform a brute force approach in terms of memory and time. The SSTH-tree is more efficient in terms of memory, whereas the SSTT-tree is more efficient in terms of time.

Authors: Vikram Parmar, Gert Groeneveld, Ashis Jalote-Parmar, David Keyson
Venue: Proceedings of the 3rd International Conference on Tangible and Embedded Interaction (2009)

The paper presents a case of tangible user interface (TUI), which has been designed using traditional metaphors to access personal health information through an ICT based health system. An evaluative study of the designed TUI was conducted with (n=175) rural women in western India. The interaction with TUI was compared with previously designed customized iconic keyboard of an existing personal health information system. The results from the study illustrate that proposed TUI increased social interaction due to enhanced product engagement, product attachment, and community decision-making. As a consequence of increased social interaction, sensitive health information has been disseminated successfully to the rural women.
Approximating Probabilistic Behaviors of Biological Systems Using Abstract Interpretation
Authors: Alessio Coletta, Roberta Gori, Francesca Levi
Venue: Electronic Notes in Theoretical Computer Science (ENTCS) (2009)

In this paper we apply the Abstract Interpretation approach [P. Cousot and R. Cousot. Abstract Interpretation: A Unified Lattice Model for Static Analysis of Programs by Construction or Approximation of Fixpoints. Proc. of POPL'77, 238-252, 1977; P. Cousot and R. Cousot. Systematic Design of Program Analysis Frameworks. Proc. of POPL'79, 269-282, 1979] for approximating the behavior of biological systems, modeled specifically using the Chemical Ground Form calculus [L. Cardelli. On Process Rate Semantics. Theoretical Computer Science, 391 190-215, 2008], a new stochastic calculus rich enough to model the dynamics of biochemical reactions. Our analysis computes an Interval Markov Chain (IMC) that safely approximates the Discrete-Time Markov Chain, describing the probabilistic behavior of the system, and reports both lower and upper bounds for probabilistic temporal properties. Our analysis has several advantages: (i) the method is effective (even for infinite state systems) and allows us to systematically derive an IMC from an abstract labeled transition system; (ii) using intervals for abstracting the multiplicity of reagents allows us to achieve conservative bounds for the concrete probabilities of a set of concrete experiments which differs only for initial concentrations.
GPS Height Aiding Computation Using Multi-resolution Digital Terrain Models
Authors: Jing Li, Claire Jarvis
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 03 (2009)

This paper investigates how the accuracy of astandalone GPS receiver changes when the height derived from a Digital Terrain Model (DTM) is used as an extra equation in the single-point least squares solution. The results show that height aiding using a DTM can improve the accuracy of a GPS receiver when the number of satellites is low and PDOP (Position Dilution of Precision) is high.
A List Scheduling Algorithm for Scheduling Multi-user Jobs on Clusters
Authors: Jorge Barbosa, António P. Monteiro
Venue: High Performance Computing for Computational Science - VECPAR 2008: 8th International Conference, Toulouse, France, June 24-27, 2008. Revised Selected Papers (2008)

This paper addresses the problem of scheduling multi-user jobs on clusters, both homogeneous and heterogeneous. A user job is composed by a set of dependent tasks and it is described by a direct acyclic graph (DAG). The aim is to maximize the resource usage by allowing a floating mapping of processors to a given job, instead of the common mapping approach that assigns a fixed set of processors to a user for a period of time. The simulation results show a better cluster usage. The scheduling algorithm minimizes the total length of the schedule (makespan) of a given set of parallel jobs, whose priorities are represented in a DAG. The algorithm is presented as producing static schedules although it can be adapted to a dynamic behavior as discussed in the paper.
