A method of creating new valency entries
Authors: Sanae Fujita, Francis Bond
Venue: Machine Translation (2007)

Information on subcategorization and selectional restrictions in a valency dictionary is important for natural language processing tasks such as monolingual parsing, accurate rule-based machine translation and automatic summarization. In this paper we present an efficient method of assigning valency information and selectional restrictions to entries in a bilingual dictionary, based on information in an existing valency dictionary. The method is based on two assumptions: words with similar meaning have similar subcategorization frames and selectional restrictions; and words with the same translations have similar meanings. Based on these assumptions, new valency entries are constructed for words in a plain bilingual dictionary, using entries with similar source-language meaning and the same target-language translations. We evaluate the effects of various measures of semantic similarity.

Authors: Akiyuki Minamide, Kazuya Takemata, Nobuyuki Naoe, Hirofumi Yamada, Pee Suat Hoon
Venue: Proceedings of the Fifth IEEE International Conference on Wireless, Mobile, and Ubiquitous Technology in Education (2008)

This paper described the outline of a Long-Distance-Controlled Robot (LDCR) System for engineering education. In the LDCR system, the players operate the robots on one physical site via the Internet. To confirm whether the developed system was able to be used, we held exchange association between the elementary schools in Japan by the robot game named ‘Ball Rolling Game’ using this system. It was clarified that our system could be used for the exchange association between the elementary schools from the results of the questionnaire. In addition, we tried the international exchange between Singapore and Japan using the system.
Electronic Records Management in Local Government Agencies: The Case of the Clerk of Courts Office in Lake County Florida
Authors: James L. Parrish,  Jr., James F. Courtney
Venue: Information Systems Management (2007)

Local governments must provide public access to records such as court proceedings, deeds, marriage licenses, birth, and death records, and so on, often on tight budgets. This article focuses on how a local agency, the Clerk of Courts office in Lake County, Florida, used a planning process developed by the National Center for State Courts. This process was loosely coupled with the principles of sensemaking (Weick, 1995) to stay ahead of the curve concerning changes that would significantly affect its records management system. By applying the scanning methods, the organization was able to paint a plausible picture of its future environment that allowed it to attack the issues related to legislative changes in its electronic records management (ERM) practices proactively rather than reactively.
Providing platform heterogeneity-awareness for data center power management
Authors: Ripal Nathuji, Canturk Isci, Eugene Gorbatov, Karsten Schwan
Venue: Cluster Computing (2008)

Power management is becoming an increasingly critical component of modern enterprise computing environments. The traditional drive for higher performance has influenced trends towards consolidation and higher densities, artifacts enabled by virtualization and new small form factor server blades. The resulting effect has been increased power and cooling requirements in data centers which elevate ownership costs and put more pressure on rack and enclosure densities. To address these issues, we exploit a fundamental characteristic of data centers: "platform heterogeneity". This heterogeneity stems from the architectural and management-capability variations of the underlying platforms. We define an intelligent heterogeneity-aware load management (HALM) system that leverages heterogeneity characteristics to provide two data center level benefits: (i) power efficient allocations of workloads to the best fitting platforms and (ii) improved overall performance in a power constrained environment. Our infrastructure relies upon platform and workload descriptors as well as a novel analytical prediction layer that accurately predicts workload power/performance across different platform architectures and power management capabilities. Our allocation scheme achieves on average 20% improvements in power efficiency for representative heterogeneous data center configurations, and up to 18% improvements in performance degradation when power budgeting must be performed. These results highlight the significant potential of heterogeneity-aware management.

Authors: Shaneel Narayan, Samad Kolahi, Rick Waiariki, Madeleine Reid
Venue: Proceedings of the 2nd WSEAS International Conference on Computer Engineering and Applications (2008)

In this paper, in a laboratory environment the performance of four different operating systems (Windows NT4, Windows 2000, Windows 2003, and Linux Fedora) are compared. The performance parameters measured are bandwidth and network delay. Linux Fedora provided the highest bandwidth for a file server at 17.1Mbps, Windows 2000 was fastest for a FTP (83.2Mbps), and Windows 2003 and Windows 2000 gave the highest bandwidth for a web server (4.3Mbps and 4.5Mbps respectively).
An efficient centralized scheduling algorithm for IEEE 802.16 multi-radio mesh networks
Authors: Jun Wang, Weijia Jia, Liusheng Huang
Venue: Proceedings of the 2nd international conference on Ubiquitous information management and communication (2008)

In centralized scheduling for IEEE 802.16 mesh networks, all packets should be transported through the BS (Base Station). The links to or from the BS become the system's bottleneck and the throughput is heavily impacted by the interference. To solve this problem, multiple radios are equipped in some stations to increase the bandwidth of these links. This paper proposes a new efficient scheduling algorithm for IEEE 802.16 mesh mode. It is a centralized scheduling algorithm that considers the usage of multiple radios. Extensive simulation results obtained from different configurations are presented. The result shows that our algorithm has improved the system performance in the aspects of scheduling length, transmission delay, channel utilization ratio and system throughput.
An integrated information system for product design planning
Authors: Hsu-Fang Hung, Hsing-Pei Kao, Ying-Shen Juang
Venue: Expert Systems with Applications: An International Journal (2008)

In recent years, new product development (NPD) has become more and more competitive and globalized, and the planning phase is absolutely critical for the success of a NPD project. Quality function deployment (QFD) has been recognized as one of the most important approaches for NPD. Nevertheless, the issues of product design scheduling and costing have not been explicitly addressed in the deployment process. On the other hand, the design structure matrix (DSM), a popular representation and analysis technique, has led to its increasing use in a variety of contexts, including product development, project management and system engineering. In this paper, we develop a novel framework which integrates QFD and DSM to support product design planning, including product architecture/components deployment, design scheduling and costing. A knowledge-based database is developed to support the proposed framework. The details are presented and a prototype product design planning system is implemented with a practical application in the semiconductor industry, system-on-a-chip product design planning, to validate the completeness and benefits of the proposed approach.
The Compression Intensity Index: A practical anatomical estimate of the biomechanical risk for a deep tissue injury
Authors: Amit Gefen
Venue: Technology and Health Care (2008)

Pressure-related deep tissue injury (DTI) is a severe form of pressure ulcer that initiates in compressed muscle tissues under bony prominences, and progresses superficially towards the skin. Patients with impaired motosensory capacities are at high risk of developing DTI. There is a critical medical need for developing risk assessment tools for DTI. A new anatomical index, the Compression Intensity Index: CII = (BW/Rt){1/2}, which depends on the body weight (BW), radius of curvature of the ischial tuberosities (R) and thickness of the underlying gluteus muscles (t), is suggested for approximating the loading intensity in muscle tissue during sitting in permanent wheelchair users, as part of a clinically-oriented risk assessment for DTI. Preliminary CII data were calculated for 6 healthy and 4 paraplegic subjects following MRI scans, and data were compared between the groups and with respect to a gold standard, being a previously developed subject-specific MRI-finite-element (MRI-FE) method of calculating muscle tissue stresses (Linder-Ganz et al., J. Biomech. 2007). Marked differences between the R and t parameters of the two groups caused the CII values of the paraplegics to be < 1.6-fold higher than for the healthy (p<0.001), thereby indicating on the sensitivity of this parameter to the pathoanatomical changes that occur in the buttocks with paraplegia. Data of CII correlated reasonably with the gold standard calculations of MRI-FE muscle stresses (correlation coefficient 0.65). Since CII measurements do not require highly-specialized biomechanical numerical analyses such as MRI-FE, CII has the potential to serve as a practical, quick, and cost-effective approximation of the loading intensity in muscles of wheelchair-bound or bedridden patients. Hence, CII measurements can be integrated into DTI-risk-assessment tools, the need of which is now being discussed intensively in the American and European Pressure Ulcer Advisory Panel meetings.
Simulation optimization and correlation with multi stage Monte Carlo optimization
Authors: Wiliam Conley
Venue: International Journal of Systems Science (2007)

The importance of simulation in our complex computer laden 21st century cannot be overstated. Also optimization is of vital concern in business, industry, engineering and science. These fields frequently require analyzing sets of data to see whether variables are correlated or can be used in forecasting. Presented here is an attempt to combine these three areas with a new correlation statistic for single or multivariate, linear or nonlinear work that can be calculated using the multistage Monte Carlo optimization algorithm in our computer age. Several examples will be presented along with an explanation of how to simulate the sampling distributions for subsequent testing of correlation hypotheses.
Supporting Rich Interaction in the Classroom with Mobile Devices
Authors: Gustavo Zurita, Nelson Baloian, Felipe Baytelman
Venue: Proceedings of the Fifth IEEE International Conference on Wireless, Mobile, and Ubiquitous Technology in Education (2008)

Mobile computing devices facilitate mobility and face-to-face interaction when compared with desktop computing, but lacks of the computing power of the latter. Therefore, a key aspect to ensure success of a learning supporting mobile application is whether mobility is really needed for the activity it supports and if mobile devices do really represent an added value compared with the same application implemented on non-mobile devices. In this work we first analyze the best known collaborative learning practices trying to find out which are the real need for mobility and face-to-face interaction and then design and develop an application called MC-Supporter implementing a, problem-based, collaborative learning application based on these requirements.
Separating the communication complexities of MOD m and MOD p circuits
Authors: V. Grolmusz
Venue: Proceedings of the 33rd Annual Symposium on Foundations of Computer Science (1992)

The author proves in this paper that it is much harder to evaluate depth-2, size-N circuits with MOD m gates than with MOD p gates by k-party communication protocols: he shows a k-party protocol which communicates O(1) bits to evaluate circuits with MOD p gates, while evaluating circuits with MOD m gates needs Omega (N) bits, where p denotes a prime, and m a composite, non-prime power number. As a corollary, for all m, he shows a function, computable with a depth-2 circuit with MOD m gates, but not with any depth-2 circuit with MOD p gates. He proves in the second part that the GIP function by L. Babai et al. (1989) needs exponential size in n when it is computed by some depth-3 circuits, with threshold, symmetric, and MOD m gates.
mStruct: a new admixture model for inference of population structure in light of both genetic admixing and allele mutations
Authors: Suyash Shringarpure, Eric P. Xing
Venue: Proceedings of the 25th international conference on Machine learning (2008)

Traditional methods for analyzing population structure, such as the Structure program, ignore the influence of mutational effects. We propose mStruct, an admixture of population-specific mixtures of inheritance models, that addresses the task of structure inference and mutation estimation jointly through a hierarchical Bayesian framework, and a variational algorithm for inference. We validated our method on synthetic data, and used it to analyze the HGDP-CEPH cell line panel of microsatellites used in (Rosenberg et al., 2002) and the HGDP SNP data used in (Conrad et al., 2006). A comparison of the structural maps of world populations estimated by mStruct and Structure is presented, and we also report potentially interesting mutation patterns in world populations estimated by mStruct, which is not possible by Structure.
Evaluation of process parameter space of bulk FinFETs using 3D TCAD
Authors: Muhammad Nawaz, Stefan Decker, Luis-Felipe Giles, Wolfgang Molzer, Thomas Schulz
Venue: Microelectronic Engineering (2008)

Using full 3D TCAD, an evaluation of process parameter space of bulk FinFET is presented from the point of view of DRAM, SRAM and I/O applications. Process and device simulations are performed with varying uniform fin doping, anti-punch implant dose and energy, fin width, fin height and gate oxide thickness. Bulk FinFET architecture with anti-punch implant is introduced beneath the channel region to reduce the punch-through and junction leakage. For 30nm bulk FinFET, anti-punch implant with low energy of 15 to 25keV and dose of 5.0x10^1^3 to 1.0x10^1^4cm^-^2 is beneficial to effectively suppress the punch-through leakage with reduced GIDL and short channel effects. Our simulations show that bulk FinFETs are approximately independent of back bias effect. With identical fin geometry, bulk FinFETs with anti-punch implant show same I"O"N-I"O"F"F behavior and approximately equal short channel effects like SOI FinFETs.
Optimistic transactional active replication
Authors: Hiroshi Horii, Hayato Yamana
Venue: Proceedings of the 2nd international conference on Ubiquitous information management and communication (2008)

Critical database applications require 2-safe replication between at least two sites for disaster-tolerant services. At the same time, they must provide consistent and low-latency results to their clients in normal cases. In this paper, we propose Optimistic Transactional Active Replication (OTAR), which replicates the transaction logs with low latency and provides a consistent view to database applications. The latency of our replication is lower than Passive Replication, and guarantees the serializability of transaction isolation levels that cannot be supported by Active Replication. For our replication, each client sends a transaction request to all replicas and all of the replicas execute the request and optimistically return the result of the transaction to the client. Each replica generates a causality history of the transaction, sent to the client with the result. With the causality histories, the client can make sure that the requested transaction was executed in the same order at all of the replicas and eventually commit it. If the client cannot validate the order, then the client waits for the pessimistic result of the transaction from the replicas. This paper describes the algorithm and its properties.
An aspect-oriented approach for improving architecture design efficiency
Authors: Thorsten Keuler
Venue: Companion of the 30th international conference on Software engineering (2008)

Major issues in software engineering today are the ever increasing size and complexity of systems with, at the same time, high demands for quality. Software architectures are a means for coping with size and complexity of systems and also for assuring required qualities. The processes of creating architectures, however, remain affected by these issues. Since, in practice, architectures have to be constructed iteratively, the number of established architectural strategies and the number of inter-related models heavily increase over time. Hence, the impact analysis of newly introduced quality strategies during later stages becomes highly effort-intensive and error-prone. With our approach we aim at the mitigation of effort needed for such quality impact analyses by enabling efficient separation of concerns. For achieving efficiency, we introduce an aspect-oriented approach that enables the automatic weaving of quality strategies into architectural artifacts. By doing so, we are able to conduct selective quality impact evaluations with significantly reduced effort.

Venue: Computing in Science and Engineering (2008)

The adoption of large-scale distributed computing for high-energy physics presents new opportunities and challenges for physicists analyzing the data from the Large Hadron Collider experiments. With petabytes of data to manage, accessed by thousands of systems and used by thousands of collaborators, effective provenance is critical to the understanding of how the physics results were produced. In this article, the authors discuss several uses of data provenance in high-energy physics workflows and the opportunities for improvements in data analysis workflows that result from decentralized provenance collection and fine-grained object annotations.
A New Centroid-Based Classifier for Text Categorization
Authors: Lifei Chen, Yanfang Ye, Qingshan Jiang
Venue: Proceedings of the 22nd International Conference on Advanced Information Networking and Applications - Workshops (2008)

In recent years, centroid-based document classifiers receive wide interests from text mining community because of their simplicity and linear-time complexity. However, the traditional centroid-based classifiers ususally perform less effectively for Chinese text categorization. In this paper, we tackle the problem by developping a new way to calculate the class-specific weights for each term in the training phase; in the testing phase, the new documents are assigned to the centroid to which the document is most similar based on the weighted distance measurement. The experimental results demonstrate that the accuracy of our algorithm outperforms the traditional centroid-based classifiers, as well as outstanding efficiency compared with the Support Vector Machine (SVM) based classifers for Chinese text categorization.
Software engineering for multicore systems: an experience report
Authors: Victor Pankratius, Christoph Schaefer, Ali Jannesari, Walter F. Tichy
Venue: Proceedings of the 1st international workshop on Multicore software engineering (2008)

The emergence of inexpensive parallel computers powered by multicore chips combined with stagnating clock rates raises new challenges for software engineering. As future performance improvements will not come "for free" from increased clock rates, performance critical applications will need to be parallelized. However, little is known about the engineering principles for parallel general-purpose applications. This paper presents an experience report with four diverse case studies on multicore software development for general-purpose applications. They were programmed in different languages and benchmarked on several multicore computers. Empirical findings include: 1) Multicore computers deliver: Real speedups are achievable, albeit with significant programming effort and speedups that are typically lower than the number of cores employed; 2) Massive refactoring of sequential programs is required, sometimes at several levels. Special tools for parallelization refactorings appear to be an important area of research; 3) Autotuning is indispensable, as manually tuning thread assignment, number of pipeline stages, size of data partitions and other parameters is difficult and error prone; 4) Architectures that encompass several parallel components are poorly understood. Tuneable architectural patterns with parallelism at several levels need to be discovered.
Resolving heterogeneity of Web-service composition in network manufacturing based on ontology
Authors: Derong Shen, Ge Yu, Yue Kou, Tiezheng Nie, Zhibin Zhao
Venue: International Journal of Computer Integrated Manufacturing (2007)

Web-service composition provides more powerful service functions through integrating existing Web services on the Internet, and collaborative working and resource-sharing among enterprises on the Internet have become a popular trend by means of Web-service composition technologies. Network manufacturing plays an important role in the manufacturing domain and can be realized based on Web-service composition. However, heterogeneity exists widely in complicated Web-service composition, except for manufacturing resources, and this must be resolved. In this paper, we focus on the heterogeneity existing in the execution of composite Web services in network manufacturing, in which the heterogeneity is classified into the heterogeneity between semantic equivalent Web services and the heterogeneity between subsequent Web services in a composite service. We summarize five types of conflicts, namely Semantic Conflict, Parameter Data Type Conflict, Parameter Structure Conflict, Parameter Number Conflict, and Parameter Data Unit Conflict. According to these five types of conflicts, an ontology-based approach for resolving them is proposed, including the definition of domain business process ontology knowledge, domain and industry ontology knowledge, and meta-ontology knowledge about transformation rules. Finally, a case is given, and the implementation technologies are introduced. The ontology based on heterogeneity resolution policy should be established as middleware and applied to any domain to make Web-service composition more available.
