Ratioed power and rate control for CDMA wireless networks
Authors: Jui Teng Wang
Venue: Wireless Communications Mobile Computing (2009)

We propose in this paper the ratioed power and rate control (RPRC) algorithm to satisfy the requirements of both the data rate and the signal quality. During the execution of the RPRC algorithm, only the representative user in each cell adjusts its power level according to certain distributed power control algorithm, and the ratio of the power level for the non-representative user to that for the representative user is kept constant. When the RPRC algorithm is finished, the power levels for all users remain unchanged and the transmission rate is determined by the available rate. We show that the RPRC algorithm can be used for allocating the bandwidth of each cell and achieving the required rate of each user. Furthermore, simulation results reveal that the RPRC algorithm results in larger throughput and finds a feasible power set faster than the other algorithm.

Reducing emergency department overcrowding: five patient buffer concepts in comparison
Authors: Erik M. W. Kolb, Sebastian Schoening, Jordan Peck, Taesik Lee
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

Emergency Department (ED) overcrowding is a common medical care issue in the United States and other developed nations. One major cause of ED crowding are holding patients waiting in the Emergency Room (ER) for inpatient unit admission where they block critical ED resources. With input data from a hospital in Massachusetts/USA, we tested five patient buffer concepts which aim at relieving pressure of the ER. The buffers are also assumed to improve patient and staff satisfaction through their design tailored to needs in patient flow. To ensure patients safety, we performed tests with discrete event simulation in which we discovered 'triage to bed time' reductions of up to 22% and 'diversion hour' decreases of up to 24%. All buffers managed to run with significantly less resources than the ER. Our findings have a potential impact on hospital process flow due to clear results which offer substantial improvement of hospital organization.
Preliminary exploration on different concepts of knowledge based on the meaning of information
Authors: Sufen Wang, Ping Cang
Venue: Proceedings of the 3rd WSEAS international conference on Computer engineering and applications (2009)

Dretske observes that an essential component for the notion of 'to know' is information provision. Following Dretske, we discuss the meaning of information based on data embody information provision. We analyze four basic relationships between information and dada (i.e. four types of meaning) by using formal context, namely, fully matched, the first partly matched, the second partly matched and unmatched, and obtain their physical signification. Then we look at how data convey information content, and how the types of meaning relate to different concepts of knowledge.
A Queuing Analysis of Tolerating for Denial-of-Service (DoS) Attacks with a Proxy Network
Authors: Myint Myint Aye
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 02 (2009)

Denial of Service is becoming a growing concern. As our systems communicate more and more with other that we know less and less, they become increasingly vulnerable to hostile intruders who may take advantage of the very protocols intended for the establishment and authentication of communication to tie up our resources and disable our servers. Since these attacks occur before parties are authenticated to each other. Proxy network based defense has recently emerged to address an open research challenge-protecting Internet service application from Denial of Service (DoS) attacks. Such schemes use a proxy network as a mediator for a hidden application to prevent direct attacks on the application’s physical infrastructure, while maintaining communication between users and the application. The proxy network provides a distributed front-end to disperse DoS attack traffic, thereby shielding the application. However, the basic feasibility and fundamental properties of such schemes remain unclear, posing critical challenges for their use. Resisting Denial of Service (DoS) attacks is an important open research. This work explores the use of overlay proxy networks to protect applications against DoS attacks. The analysis shows that proxy network-based DoS defense can effectively resist these attacks and protect application successfully.
The calendar is crucial: Coordination and awareness through the family calendar
Authors: Carman Neustaedter, A. J. Bernheim Brush, Saul Greenberg
Venue: ACM Transactions on Computer-Human Interaction (TOCHI) (2009)

Everyday family life involves a myriad of mundane activities that need to be planned and coordinated. We describe findings from studies of 44 different families' calendaring routines to understand how to best design technology to support them. We outline how a typology of calendars containing family activities is used by three different types of families&mdash;monocentric, pericentric, and polycentric&mdash;which vary in the level of family involvement in the calendaring process. We describe these family types, the content of family calendars, the ways in which they are extended through annotations and augmentations, and the implications from these findings for design.

Trustworthy Log Reconciliation for Distributed Virtual Organisations
Authors: Jun Ho Huh, John Lyle
Venue: Proceedings of the 2nd International Conference on Trusted Computing (2009)

Secure management of logs in an organisational grid environment is often considered a task of low priority. However, it must be rapidly upgraded when the logs have security properties in their own right. We present several use cases where log integrity and confidentiality are essential, and propose a log reconciliation architecture in which both are ensured. We use a combination of trusted computing and virtualization to enable blind log analysis, allowing users to see the results of legitimate queries, while still withholding access to privileged raw data.
A mode-based meta-model for the frequency response functions of uncertain structural systems
Authors: L. Pichler, H. J. Pradlwarter, G. I. Schuëller
Venue: Computers and Structures (2009)

Frequency response functions (FRFs) play an important role in the assessment of the structural response of linear systems subjected to dynamic forces. In this work a functional relation (meta-model) between the uncertain structural parameters and the model properties is presented. The meta-model provides a computationally fast solution to approximate the eigenfrequencies and mode shapes needed thereafter for evaluating the FRFs. The meta-model circumvents the repeated solution of the eigenvalue problem for each set of uncertain structural input parameters. The provided relations can be helpful in the design stage to control the dynamic response within certain frequency bands. Moreover, the meta-model can be used for optimization and reliability assessments based on Monte Carlo sampling procedures. Numerical examples show the application of the method focusing mainly on the variability of the FRFs. The efficiency and accuracy of the meta-model to compute approximate FRFs is assessed by a comparison with the solution by Finite Element (FE) analyses.
From Bruhat intervals to intersection lattices and a conjecture of Postnikov
Authors: Axel Hultman, Svante Linusson, John Shareshian, Jonas Sjöstrand
Venue: Journal of Combinatorial Theory Series A (2009)

We prove the conjecture of A. Postnikov that (A) the number of regions in the inversion hyperplane arrangement associated with a permutation w@?S"n is at most the number of elements below w in the Bruhat order, and (B) that equality holds if and only if w avoids the patterns 4231, 35142, 42513 and 351624. Furthermore, assertion (A) is extended to all finite reflection groups. A byproduct of this result and its proof is a set of inequalities relating Betti numbers of complexified inversion arrangements to Betti numbers of closed Schubert cells. Another consequence is a simple combinatorial interpretation of the chromatic polynomial of the inversion graph of a permutation which avoids the above patterns.
Inferring comprehensible business/ICT alignment rules
Authors: Bjorn Cumps, David Martens, Manu De Backer, Raf Haesen, Stijn Viaene, Guido Dedene, Bart Baesens, Monique Snoeck
Venue: Information and Management (2009)

We inferred business rules for business/ICT alignment by applying a novel rule induction algorithm on a data set containing rich alignment information polled from 641 organisations in 7 European countries. The alignment rule set was created using AntMiner+, a rule induction technique with a reputation of inducing accurate, comprehensible, and intuitive predictive models from data. Our data set consisted of 18 alignment practices distilled from an analysis of relevant publications and validated by a Delphi panel of experts. The goal of our study was to describe practical guidelines for managers in obtaining better alignment of ICT investments with business requirements. Our obtained rule set showed the multi-disciplinary nature of B/ICT alignment. We discuss implication of the alignment rules for practitioners.

Simulation-based sustainable manufacturing system design
Authors: Juhani Heilala, Saija Vatanen, Hannele Tonteri, Jari Montonen, Salla Lind, Björn Johansson, Johan Stahre
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

Manufacturing simulation and digital engineering tools and procedures have had a positive impact on the manufacturing industry. However, to design a sustainable manufacturing system, a multitude of system dimensions must be jointly optimized. This paper proposes an integrated simulation tool helping to maximize production efficiency and balance environmental constraints already in the system design phase. Lean manufacturing, identification and elimination of waste and production losses, and environmental considerations are all needed during development of a sustainable manufacturing system. Engineers designing the manufacturing system need decision support, otherwise sub-optimization is more likely to occur. We present methods for calculating energy efficiency, CO2 emissions and other environmental impacts integrated into factory simulation software.
Remote Attestation of Attribute Updates and Information Flows in a UCON System
Authors: Mohammad Nauman, Masoom Alam, Xinwen Zhang, Tamleek Ali
Venue: Proceedings of the 2nd International Conference on Trusted Computing (2009)

UCON is a highly flexible and expressive usage control model which allows an object owner to specify detailed usage control policies to be evaluated on a remote platform. Assurance of correct enforcement is mandatory for the establishment of trust on the remote platform claiming to implement UCON. Without such an assurance, there is no way of knowing whether the policies attached to the objects will be enforced as expected. Remote attestation, an important component of Trusted Computing, is highly suitable for establishing such an assurance. Existing approaches towards remote attestation work at a very coarse-grained level and mostly only measure binary hashes of the applications on the remote platform. Solutions at this level of abstraction cannot provide assurance to a challenger regarding behavior of a remote platform concerning enforcement of the owner's policies. In this paper, we provide a new remote attestation technique which allows a challenger to verify two important behaviors of a UCON system enforcing its policies. These two behaviors are the attribute update behavior and information flow behavior. Measuring, storing and reporting these behaviors in a trusted manner is described in detail and a mechanism for the verification of these behaviors against the original UCON policies is provided. The end result is a flexible and scalable technique for establishing trust on attribute updates and information flow behaviors of a remote UCON system.
The Value of Weights in Automatically Generated Text Structures
Authors: Dana Dannélls
Venue: Proceedings of the 10th International Conference on Computational Linguistics and Intelligent Text Processing (2009)

One question that arises if we want to evolve generation techniques to accommodate Web ontologies is how to capture and expose the relevant ontology content to the user. This paper presents an attempt to answer the question about how to select the ontology statements that are significant for the user and present those statements in a way that helps the user to learn. Our generation approach combines bottom-up and top-down techniques with enhanced comparison methods to tailor descriptions about a concept described in an ontology. A preliminary evaluation indicates that the process of computing preferable property weights in addition to enhanced generation methods has a positive effect on the text structure and its content. Future work aims to assign grammar rules and lexical entries in order to produce coherent texts that follow on from the generated text structures in several languages.
A layered United States Universal Service Fund for an everything-over-IP world
Authors: Scott Jordan
Venue: Telecommunications Policy (2009)

Support through the United States Federal Universal Service Fund for high-cost areas has been principally defined in terms of telephone service. Fund growth due to increases in wireless lines and implicit support for broadband infrastructure has created an untenable situation, and fundamental reform is expected. The cause underlying this growth is convergence between the telephone network, wireless networks, the Internet, and cable networks. This convergence will pose additional serious long-term challenges to the fund. This paper proposes a restructuring of the high-cost funds based on a layered model. Both contributions and distributions are focused on network infrastructure, without distinction between voice and broadband. The proposal uses a new definition of communication services to guarantee technology neutrality, and includes service area reform and cost efficiency measures. This layered approach repositions the fund for future converged networks.
Identifying differences between CAD and physical mock-ups using AR
Authors: Sabine Webel, Mario Becker, Didier Stricker, Harald Wuest
Venue: Proceedings of the 2007 6th IEEE and ACM International Symposium on Mixed and Augmented Reality (2007)

Since the last ten years product development in automotive industry is changing radically. Most physical mock-ups have vanished and are now replaced by digital ones. But they are still needed for final evaluations or issues, which cannot be adequately simulated. During their production, deviations from the CAD model may be made. Since digital and real mock-up must match for the further product development, the transfer of differences between physical and digital mock-up to the CAD format is a crucial issue. In this paper an Augmented Reality (AR) based tool-chain is presented, which allows matching the CAD data with real mock-ups and documents the differences between them. Essential functions like measurement and online construction are provided, allowing the end-users to create information in AR space and feeding them back into the CAD model.

Authors: Yihua Lam, Saadat M. Alhashmi
Venue: Proceedings of the 11th Pacific Rim International Conference on Multi-Agents: Intelligent Agents and Multi-Agent Systems (2008)

Certification of Halal food product supply becomes a challenging task as various validating procedures have to be undergone under the emergence of vast business networks in food supply chain. In order to maintain high quality assurance of every validating procedure, and to fulfill demand from immense religious population, highly efficient method will be needed to monitor, to record and to register, to decide and to certify every actor (agent) and every product in the supply chain. With the multi-agent architecture this research work simulates the Halal food supply chain planning with certification system, which attempts to replicate the actual market place coupled with Halal food quality requirement. Statistical study of the decision making of various agents in the supply chain and the response of certification system will verify the feasibility of the certification framework in supply chain.
Retrieval from episodic memory: Neural mechanisms of interference resolution
Authors: Maria Wimber, Roland Marcus Rutschmann, Mark W. Greenlee, Karl-Heinz Bäuml
Venue: Journal of Cognitive Neuroscience (2009)

Selectively retrieving a target memory among related memories requires some degree of inhibitory control over interfering and competing memories, a process assumed to be supported by inhibitory mechanisms. Evidence from behavioral studies suggests that such inhibitory control can lead to subsequent forgetting of the interfering information, a finding called retrieval-induced forgetting [Anderson, M. C., Bjork, R. A., & Bjork, E. L. Remembering can cause forgetting: Retrieval dynamics in long-term memory. Journal of Experimental Psychology: Learning, Memory & Cognition,20, 1063-1087, 1994]. In the present functional magnetic resonance imaging study, we investigated the neural processes underlying retrieval-induced forgetting and, in particular, examined the extent to which these processes are retrieval (i.e., selection) specific. Participants actively retrieved a subset of previously studied material (selection condition), or were re-exposed to the same material for relearning (nonselection condition). Replicating prior behavioral work, selective retrieval caused significant forgetting of the nonretrieved items on a delayed recall test, relative to the re-exposure condition. Selective retrieval was associated with increased BOLD responses in the posterior temporal and parietal association cortices, in the bilateral hippocampus, and in the dorsolateral prefrontal cortex. Medial and lateral prefrontal areas showed a strong negative linear relationship between selection-related neural activity and subsequent forgetting of competitors. These findings suggest reduced demands on inhibitory control processes when interference is successfully resolved during early selective retrieval from episodic memory.

Parallel Optimal Weighted Links
Authors: Ovidiu Daescu, Yam K. Cheung, James D. Palmer
Venue: Transactions on Computational Science III (2009)

In this paper we consider parallel algorithms for computing an optimal link among weighted regions in the plane. The problem arises in several areas, including radiation therapy, geological exploration and environmental engineering. We present a CREW PRAM parallel algorithm and a coarse-grain parallel computer algorithm for this problem. For a weighted subdivision with n vertices, the work of the parallel algorithms we propose is only an O(logn) factor more than that of their optimal sequential counterparts. We further adapt an algorithm for minimizing sum of linear fractionals, that has inherent parallelism, to solve in parallel the global optimization problems associated with our solution for the weighted region optimal link problem.

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

With the development of Agile Virtual Enterprise (AVE) in the context of globalization manufacturing, Innovative design is the key problem of product in the current changing world, which is seen as the core competitiveness of AVE. However, non-structured and semi-structured knowledge on the current Internet can not meet the demands of complexity, flexibility and Real-time for innovation design. Until the emergence of the semantic web, it is possible for innovative design based on semantics web services. We give a new knowledge management methodology based on semantics web services to support innovative design. This method gives ontology for innovative design which including design, process, skill, application domain and organization sub ontology. Then we proposes the innovative design method (SEM-PDM) based on semantic web services by combining knowledge engineering, and select the domain of environmental protection device manufacturing as the application field. In the end, an environmental protection device manufacturing ontology architecture is give and a case study is shown.
