iARRIVE: An Incremental Algorithm for Robust Relative Influence Values Elicitation
Authors: S. E. Hegazy, C. D. Buckingham
Venue: Proceedings of the 2009 International Conference on eHealth, Telemedicine, and Social Medicine (2009)

This paper proposes an incremental approach to solving node weightings in a tree structure. The tree represents expertise used to quantify risks associated with mental health problems and it is incorporated within a web based decision support system called GRiST. The aim of the algorithm is to find the set of relative node weightings in the tree that helps GRiST simulate the clinical risk judgements given by mental health experts. This paper extends the solution presented in our earlier ARRIVE algorithm, to incorporate a larger pool of data and previous cases in the solution, hence producing better elicitation results. It is also useful in incorporating new cases into the GRiST tree parameters estimation process, one by one as they are encountered. The original ARRIVE algorithm showed that a very large number of nodes (several thousand for GRiST) can have their weights calculated from the clinical judgements associated with a few hundred cases (about 200 for GRiST). The new algorithm, iARRiVE, allows GRiST to learn by updating the node weightings to account for new cases. The results show that it can provide the best fit to an unlimited set of cases and thus ensure GRiST parameters provide the optimal solution for all the cases in its memory. Its solution can be applied to similar knowledge engineering domains where relative weightings of node siblings are part of the parameter space

Venue: ACM SIGGRAPH ASIA 2008 computer animation festival (2008)

Sony Pictures Imageworks was one of a few, select studios contributing to the ground-breaking VFX of "Speed Racer." Led by Senior Visual Effects Supervisor Kevin Mack, Imageworks completed three exhilarating racing sequences: Desert Flats, Mountain Rally, and Mountain Switchback. In Desert Flats, Imageworks' Marco Marenghi and his animation team added a sense of weight and realistic speed to all the elaborate cars and their exotic drivers. Patrick Witting's complex fluid-dust simulations and Theo Vandernoot's rigid-body simulations of debris and dirt further enhanced the realistic motion of the sequence. Imageworks' skilled lighters and compositors combined all the layers of these particular shots, ensuring the consistency of the pop-art/saturated look that Warner Bros. Visual Effects Supervisors John Gaeta and Dan Glass had envisioned from the beginning.
Glitch-free design for multi-threshold CMOS NCL circuits
Authors: Ahmad Al Zahrani, Andrew Bailey, Guoyuan Fu, Jia Di
Venue: Proceedings of the 19th ACM Great Lakes symposium on VLSI (2009)

In this paper, a novel design is proposed for eliminating glitches and signal bounces during wake-up events that result from incorporating multi-threshold CMOS (MTCMOS) into asynchronous NULL Convention Logic (NCL) circuits. A one-stage 8x8 NCL array multiplier is designed using the proposed method and compared with the previously published paradigm. Evaluation results of glitches, throughput, and power efficiency have shown advantages of the proposed design in all these categories over the state-of-the-art. The effect of supply voltage scaling on the proposed design is also examined and presented.
Improving error tolerance for multithreaded register files
Authors: Lei Wang, Niral Patel
Venue: IEEE Transactions on Very Large Scale Integration (VLSI) Systems (2008)

Chip multithreaded computing is exposed to the dual challenges of increasing system complexity and error sensitivity. It is critical to develop effective solutions that achieve better error tolerance without inducing performance degradation. In this paper, we propose a new error-tolerant memory design based on a unique computing phenomenon referred to as the dynamic multithreading redundancy (DMR). The proposed technique exploits the interplay between the concurrent threads for runtime error control. We also present two DMR enhancements, immediate write-back and self-recovery, to address the error accumulation effect. A multithreaded register file was implemented to demonstrate the proposed DMR technique. Simulation results on the SPEC CPU2000 benchmarks demonstrate significant overhead reduction in performance and energy efficiency related to error recovery. In addition, the proposed technique features good scalability with respect to the instruction-level and thread-level parallelism for next-generation processor design, where the soft error problem is expected to get worse due to technology scaling and architecture-affecting trends.

Steganalysis Versus Splicing Detection
Authors: Yun Q. Shi, Chunhua Chen, Guorong Xuan, Wei Su
Venue: Proceedings of the 6th International Workshop on Digital Watermarking (2008)

Aiming at detecting secret information hidden in a given image using steganographic tools, steganalysis has been of interest for years. In particular, universal steganalysis, not limited to attacking a specific steganographic tool, is of extensive interests due to its practicality. Recently, splicing detection, another important area in digital forensics has attracted increasing attention. Is there any relationship between steganalysis and splicing detection? Is it possible to apply universal steganalysis methodologies to splicing detection? In this paper, we address these intact and yet interesting questions. Our analysis and experiments have demonstrated that, on the one hand, steganography and splicing have different goals and strategies, hence, generally causing different statistical artifacts on images. However, on the other hand, both of them make the touched (stego or spliced) image different from the corresponding original (natural) image. Therefore, natural image model based on a set of carefully selected statistical features under the machine learning framework can be used for steganalysis and splicing detection. It is shown in this paper that some successful universal steganalytic schemes can make promising progress in splicing detection if applied properly. A more advanced natural image model developed from these state-of-the-art steganalysis methods is thereafter presented. Furthermore, a concrete implementation of the proposed model is applied to the Columbia Image Splicing Detection Evaluation Dataset, which has achieved an accuracy of 92%, indicating a significant advancement in splicing detection.
Harmonic analysis of pulse-width modulated systems
Authors: Stefan Almér, Ulf Jönsson
Venue: Automatica (Journal of IFAC) (2009)

The paper considers the so-called dynamic phasor model as a basis for harmonic analysis of a class of switching systems. The analysis covers both periodically switched systems and non-periodic systems where the switching is controlled by feedback. The dynamic phasor model is a powerful tool for exploring cyclic properties of dynamic systems. It is shown that there is a connection between the dynamic phasor model and the harmonic transfer function of a linear time periodic system and this connection is used to extend the notion of harmonic transfer function to describe periodic solutions of non-periodic systems.
Simplification and aggregation strategies applied for factory analysis in conceptual phase using simulation
Authors: Matías Urenda Moris, Amos H. C. Ng, Jacob Svensson
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

Despite that simulation possesses an establish background and offers tremendous promise for designing and analyzing complex production systems, manufacturing industry has been less successful in using it as a decision support tool, especially in the conceptual phase of factory design. This paper presents how simplification and aggregation strategies are incorporated in a modeling, simulation and analysis tool, with the aim of supporting decision making in conceptual phase. Conceptual modeling is guided by a framework using an object library with generic drag and drop system components and system control objects. Data inputs are simplified by the use of Effective Process Time distributions and a novel aggregation method for product mix cycle time differences. The out coming specification is through a Web Service interface handle by modeling system architecture, automatically generating a simulation model and analysis. Case studies confirm a breakthrough in project time reduction without appreciable effects on the model's fidelity.

Dweb model: Representing Web 2.0 dynamism
Authors: Raúl Peña-Ortiz, Julio Sahuquillo, Ana Pont, José A. Gil
Venue: Computer Communications (2009)

Due to the increase in the number and popularity of applications such as e-commerce or on-line booking systems, typical of the Web 2.0, dynamic contents are becoming more and more frequent. This trend suggests the review of widely accepted paradigms and models for the World Wide Web. As a system that is continuously changing, both in the offered applications and in its infrastructure, performance evaluation studies are a main concern to provide sound proposals when designing new web-related systems. Although the dynamism in the workload characterization has also been tackled in previous research, it has not been modeled in a precise way yet because of its complex nature. In this paper we propose the Dweb model which represents the dynamism of current web applications in the workload characterization. Dweb is based on three main concepts that allow to model dynamic workload: navigation, workload test and workload distribution. In addition, a dynamic workload generator has been implemented to show the practical application of the proposed model, which has been illustrated through a case study.

On the design of reconfigurable crossbar switch for adaptable on-chip topologies in programmable NoC routers
Authors: Henrique Cota de Freitas, Philippe Olivier Alexandre Navaux
Venue: Proceedings of the 19th ACM Great Lakes symposium on VLSI (2009)

Research works have focused on high-performance on-chip interconnections with low cost and energy consumption for the next generation of many-core processors. In the same way, parallel applications will explore thread level parallelism and message-passing communication through a Network-on-Chip (NoC) to perform a high data throughput. Due to the dynamic changing of communication patterns, the goal of this paper is to present the design of Reconfigurable Crossbar Switch for NoC Routers (RCS-NR) capable of adapting topologies on demand. RCS-NR has an optimized architecture, similar area and lower energy consumption (up to 87.41%) relative to a traditional crossbar switch. Furthermore, RCS-NR-based NoC router has a similar area, higher throughput, and it is up to 98.76% more efficient in energy consumption than a conventional NoC.
Painting the ideal home: using art to express visions of technologically supported independent living for older people in north-east England
Authors: Paul Vickers, Linda Banwell, Susan Heaford, Fausto J. Sainz de Salces
Venue: Universal Access in the Information Society (2009)

This paper describes the investigation of the development of future technological products to support older people in everyday living through the agency of a community art group. Recent research has identified a number of challenges facing designers seeking to use traditional participatory design approaches to gather technology requirements data from older people. Here, a project is described that sought to get a group of older people to think creatively about their needs and desires for technological support through the medium of paint. The artistic expression technique described in this article allowed the identification of issues that had also been found by previous research that used a range of different techniques. This indicates that the approach shows promise, as it allows information to be gathered in an environment that is comfortable and familiar using methods already known by the participants and which they find enjoyable. It provides a complement (or possible alternative) to standard protocols and has the potential benefit of extracting even richer information as the primary task for participants is enjoyable in its own right and is not associated with an interrogative process. Furthermore, it is argued that some of the key risks of traditional approaches are lessened or removed by the naturalistic setting of this approach.
Routing for chip-package-board co-design considering differential pairs
Authors: Jia-Wei Fang, Kuan-Hsien Ho, Yao-Wen Chang
Venue: Proceedings of the 2008 IEEE/ACM International Conference on Computer-Aided Design (2008)

Nanometer effects have complicated the designs of chips as well as packages and printed circuit boards (PCB's). In order to improve the performance, convergence, and signal integrity of the design, chip-package-board co-design is strongly recommended by industry. In this paper, we present the first routing algorithm in the literature for chip-package-board co-design with differential-pair considerations. Our algorithm is based on linear programming and integer linear programming and guarantees to find an optimal solution for the addressed problem. It first creates globalrouting paths among chips, packages, and a PCB. Without loss of the solution optimality, our routing formulation can reduce the numbers of integer variables (constraints) by 95% (99%) on average. Then, any-angle routing is applied to complete the routing. Experimental results based on five real industry designs show that our router can achieve 100% routability and the optimal global-routing wirelength and satisfy all differential-pair constraints, under reasonable CPU times, whereas recent related work results in much inferior solution quality.
A dual threshold-based fast vertical handover scheme with authentication support
Authors: Zhiwei Yan, Huachun Zhou, Hongke Zhang, Hongbin Luo, Sidong Zhang
Venue: Proceedings of the International Conference on Mobile Technology, Applications, and Systems (2008)

Vertical handover refers to the process that the interface connecting to wireless network changes across heterogeneous networks. The delay caused by vertical handover affects the quality of the ongoing applications, especially the real-time applications like VoIP. Authentication and security association is one of the major components of delay during vertical handover. If the Mobile Node(MN) uses stateless address configuration scheme during handover, it is another time consuming phase. In this paper, we propose a dual threshold based handover scheme, which uses the Media Independent Handover (MIH) services defined in the IEEE 802.21 to provide fast vertical handover with authentication support.

Surface chemical modification of multiwalled carbon nanotubes by a wet-mechanochemical reaction
Authors: Lifei Chen, Huaqing Xie, Yang Li, Wei Yu
Venue: Journal of Nanomaterials (2008)

A wet-mechanochemical reaction for surface modification of multiwalled carbon nanotubes (CNTs) has been developed. In the treatment, CNTs reacted with potassium hydroxide in alcohol solvent at room temperature under mechanical milling. The results from Fourier transmission infrared spectroscopy demonstrate that the nonreactive surfaces of CNTs have been modified successfully by multiple hydroxyl groups. Functionalized carbon nanotubes exhibit higher zeta potential values indicating their high dispersibility in polar solvents. XRD studies corroborate that the surface functionalization does not affect the basic crystal domain size of CNTs. TEM observations reveal that CNTs have been cut into shorter ones by the milling. Shortened CNTs with functionalized surfaces show good dispersion properties.
Scheduling a maintenance activity and due-window assignment on a single machine
Authors: Gur Mosheiov, Assaf Sarig
Venue: Computers and Operations Research (2009)

We study a single machine scheduling and due-window assignment problem. In addition to the traditional decisions regarding sequencing the jobs and scheduling the due-window, we allow an option for performing a maintenance activity. This activity requires a fixed time interval during which the machine is turned off and no production is performed. On the other hand, after the maintenance time, the machine becomes more efficient, as reflected in the new shortened job processing times. The objective is to schedule the jobs, the due-window and the maintenance activity, so as to minimize the total cost consisting of earliness, tardiness, and due-window starting time and size. We introduce an efficient (polynomial time) solution for this problem.
Design of Sliding Mode Controller with Low-Pass Filter for Robot Manipulators
Authors: Jianwu Zhu, Dachang Zhu, Jinbao Cai
Venue: Proceedings of the 2009 Second International Workshop on Knowledge Discovery and Data Mining (2009)

Sliding mode control had been designed for robot manipulators at presents popularly, but the chattering is also a primary factor which infected the precise of the trace tracking of robot manipulators. This paper proposed a sliding mode control combined with a low-pass filter to deduce the influence by chattering and increase the precise of the trace tracking of robot manipulators. The stability and convergence of the designed controller are proved. The effectiveness of the proposed method is verified by simulation and experiments.
Securing publish/subscribe for multi-domain systems
Authors: Jean Bacon, David Eyers, Ken Moody, Lauri Pesonen
Venue: Proceedings of the ACM/IFIP/USENIX 2005 International Conference on Middleware (2005)

Two convincing paradigms have emerged for achieving scalability in widely distributed systems: role-based, policy-driven control of access to the system by applications and for system management purposes; and publish/subscribe communication between loosely coupled components. Publish/subscribe provides efficient support for mutually anonymous, many-to-many communication between loosely coupled entities. In this paper we focus on securing such a communication service (1) by specifying and enforcing access control policy at the service API, and (2) by enforcing the security and privacy aspects of these policies within the service itself. We envisage independent but related administration domains that share a pub/sub communications infrastructure, typical of public-sector systems. Roles are named within each domain and role-related privileges for using the pub/sub service are specified. Intra- and inter-domain, controlled interaction is supported by negotiated policies. In a large-scale publish/subscribe service, domains are not expected to trust all message brokers fully. Attribute encryption allows a single publication to carry both confidential and public information safely, even via untrusted message brokers across a vulnerable communications substrate. Our approach provides the application designer with fine-grained expressiveness while, at the same time, improving system fault tolerance by allowing a single shared messaging network to route both public and confidential information. Early simulations show that our approach reduces the overall traffic compared with a secure publish/subscribe scheme that encrypts whole messages.
