Dynamic business network process management in instant virtual enterprises
Authors: Paul Grefen, Nikolay Mehandjiev, Giorgos Kouvas, Georg Weichhart, Rik Eshuis
Venue: Computers in Industry (2009)

Nowadays, business supply chains for the production of complex products or services are likely to involve a number of autonomous organizations. The competitive market requires that these supply chains are highly agile, effective and efficient. Agility and effectiveness are obtained by forming highly dynamic virtual enterprises within supplier networks. We call these instant virtual enterprises (IVEs). The required efficiency of creating and operating IVEs can only be obtained by automated support for design, setup and enactment of business processes within these IVEs. This process support involves the dynamic composition of local processes of network members into global processes at the IVE level. This functionality goes significantly beyond traditional approaches for interorganizational workflow management. The approach, architecture and technology required for this dynamic network process management in IVEs are outlined in this paper. We show how the developed approach is applied in the automotive industry in the context of the CrossWork IST project.
Upper-Body Contour Extraction Using Face and Body Shape Variance Information
Authors: Kazuki Hoshiai, Shinya Fujie, Tetsunori Kobayashi
Venue: Proceedings of the 3rd Pacific Rim Symposium on Advances in Image and Video Technology (2009)

We propose a fitting method using a model that integrates face and body shape variance information for upper-body contour extraction. Accurate body-contour extraction is necessary for various applications, such as pose estimation, gesture recognition, and so on. In this study, we regard it as the shape model fitting problem. A model including shape variance information can fit to the contour robustly even in the noisy case. AAMs are one of these models and can fit to a face successfully. It needs appearance information for effective fitting, but it can not be used in our case because appearance of upper-body easily changes by clothes. Instead of intensity image, proposed method uses edge image as appearance information. However, discrimination between a true contour edge of upper-body and other edges is difficult. To solve this problem, we integrate shapes of upper-body and face. It is expected that this integrated model is more robust to edges in clutter background and various locations of the body than a body shape model using only body shape information. We conduct experiments and confirm improvement in accuracy by integration of face and body variance information.
A Masking Model for Motion Sharpening Phenomenon in Video Sequences
Authors: Akira Fujibayashi, Choong Seng Boon
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

In this paper, we show that motion sharpening phenomenon can be explained as a form of visual masking for a special case where a video sequence is composed of alternate frames with different level of sharpness. A frame of higher sharpness behaves to mask the ambiguity of a subsequent frame of lower sharpness and hence preserves the perceptive quality of the whole sequence. Borrowing the mechanism for visual masking, we formulated a quantitative model for deriving the minimum spatial frequency conditions which preserves the subjective quality of the frames being masked. The quantitative model takes into account three fundamental properties of the video signals, namely the size of motion, average luminance and the power of each frequency components. The psychophysical responses towards the changes of these properties are obtained through subjective assessment tests using video sequences of simple geometrical patterns. Subjective experiments on natural video sequences show that more than 75% of viewers could make no distinction between the original sequence and the one processed using the quantitative model.
A Probabilistic Multi-Cycle Model for Serving Continuous Streams from Disks
Venue: Proceedings of the 1996 International Conference on Multimedia Computing and Systems (1996)

Existing models for serving continuous streams from disks are generally based on worst-case deterministic head displacement times and on a round-robin strand service approach consisting of serving all strands once per round. We propose an alternative approach, where the head displacement time is described as a random variable with known probability density and where strands are served in a round-robin manner consecutively several times per service period. By establishing the frame loss rate separately in each cycle and for each of the strand's display deadlines, we compute the mean number of lost frames per second for a given configuration. By serving strands consecutively several times in consecutive cycles, we show that for a given frame loss rate, less buffer space is needed than in the conventional single round approach.

Analysing Biochemical Oscillation through Probabilistic Model Checking
Authors: Paolo Ballarini, Radu Mardare, Ivan Mura
Venue: Electronic Notes in Theoretical Computer Science (ENTCS) (2009)

Automated verification of stochastic models has been proved to be an effective technique for the analysis of a large class of stochastically behaving systems. In this paper we show how stochastic model-checking can be effectively applied to the analysis of biological systems. We consider a few models of biological systems taken from the literature, and we consider both their encodings as ordinary differential equations and Markovian models. We show that stochastic model-checking verification of biological systems can complement both deterministic and stochastic simulation techniques when dealing with dynamical properties of oscillators. We demonstrate how stochastic model-checking can provide exact quantitative characterization of properties of systems exhibiting oscillatory behavior, providing insights that cannot be obtained with differential equations models and that would require a large number of runs with stochastic simulation approaches.
Lean collaboration through video gestures: co-ordinating the production of live televised sport
Authors: Mark Perry, Oskar Juhlin, Mattias Esbjörnsson, Arvid Engström
Venue: Proceedings of the 27th international conference on Human factors in computing systems (2009)

This paper examines the work and interactions between camera operators and a vision mixer during an ice hockey match, and presents an interaction analysis using video data. We analyze video-mediated indexical gestures in the collaborative production of live sport on television between distributed team members. The findings demonstrate how video forms the topic, resource and product of collabora-tion: whilst it shapes the nature of the work (editing), it is simultaneously also the primary resource for supporting mutual orientation and negotiating shot transitions between remote participants (co-ordination), as well as its end prod-uct (broadcast). Our analysis of current professional activi-ties is used to develop implications for the design of future services for live collaborative video production.
A leakage-aware cache sharing technique for low-power chip multi-processors (CMPs) with private L2 caches
Authors: Hyunhee Kim, Sungjun Youn, Jihong Kim
Venue: Proceedings of the 9th workshop on MEmory performance: DEaling with Applications, systems and architecture (2008)

Power dissipation becomes an important issue in modern microprocessors such as chip multiprocessors (CMPs). Especially as the process technology advances below 90nm, the leakage power consumption becomes dominant in the total power dissipation, thus reducing the leakage power consumption is an important design goal for low-power CMPs. In particular, since most CMPs employ a large L2 cache, reducing the leakage power consumption of the L2 cache is critical in realizing low-power CMPs. In this paper, we propose a leakage-aware on-chip L2 cache organization called LACS. The proposed LACS, like the existing RACS organization, is based on a private L2 cache organization with an inter-L2 cache sharing support. However, unlike the RACS organization, which determines a peer L2 cache block for an inter-L2 cache sharing based on the reusability of the evicted L2 block and performance implications of peer L2 cache blocks, the LACS organization considers both the performance and leakage. The LACS organization reduces the leakage power consumption significantly over the leakage-oblivious RACS organization while achieving a similar performance gain over a private L2 cache organization. Experimental results show that the proposed LACS technique reduces the energy consumption by 23.6% and improves the energy delay product by 18.6% on average over the existing RACS scheme.

Authors: Wei Lin, Weiqiang Wu, Qinyu Zhang
Venue: Proceedings of the 2008 International Conference on Advanced Infocomm Technology (2008)

Due to the variety of wireless networks, the handover among heterogeneous wireless networks has become a research hotspot in recent years. More attention have been paid to the radio access network and the core network than the terminal side. In the future the mobile terminal will face a myriad of air interfaces. To roam freely in such a complex network environment, the mobile terminal should be able to handle the known and unknown air interfaces. In this paper, we proposed the smart architecture of the mobile terminal based on multiband multimode radio (MMR), Also we designed a handover strategy for the smart mobile terminal. Using the proposed strategy the mobile terminals can handover among heterogeneous wireless networks and the users can access different network at will with one equipment.

Automatic Generation of Test Inputs for Mercury
Authors: François Degrave, Tom Schrijvers, Wim Vanhoof
Venue: Logic-Based Program Synthesis and Transformation: 18th International Symposium, LOPSTR 2008, Valencia, Spain, July 17-18, 2008, Revised Selected Papers (2009)

In this work, we consider the automatic generation of test inputs for Mercury programs. We use an abstract representation of a program that allows to reason about program executions as paths in a control-flow graph. Next, we define how such a path corresponds to a set of constraints whose solution defines input values for the predicate under test such that when the predicate is called with respect to these input values, the execution is guaranteed to follow the given path. The approach is similar to existing work for imperative languages, but has been considerably adapted to deal with the specificities of Mercury, such as symbolic data representation, predicate failure and non-determinism.

Authors: Qinghua Bai, Yuejin Ma
Venue: Proceedings of the 2009 International Asia Conference on Informatics in Control, Automation and Robotics (2009)

Welding is a complex process including of physics, conducting heat, metallurgy, mechanics. when producing residual stress, crack, air holes and so on in the parts, it will reduce welding strength and welding quality. Though there are many methods to relif residual stress, it is a difficult problem about how to improve it. We use welding with trailing peening to reduce residual stress. In the process it is important to decide when to peen it. In the article, using the software ANSYS to simulate muti-welding seam process of flat, taking advantage of indirect couple method, we can know temperature field after welding, so we can be ready to peen the part.

Effects of chaotic exploration on reinforcement learning in target capturing task
Authors: Koichiro Morihiro, Teijiro Isokawa, Nobuyuki Matsui, Haruhiko Nishimura
Venue: International Journal of Knowledge-based and Intelligent Engineering Systems (2008)

A process of trial and error plays an important role in not only the human learning but also the machine learning. Such a process is called exploration in the reinforcement learning which has originated from experimental studies on learning in psychology. A uniform pseudorandom number generator appears to be suitable for exploration. However, it is known that a chaotic source also provides a random-like sequence as like as a stochastic source. By applying this random-like feature of a deterministic chaotic generator for exploration in a nonstationary shortcut maze problem, we have observed that a deterministic chaotic generator provides a better performance than a stochastic random exploration generator when used for exploration based on a logistic map. In this study, in order to confirm this difference in the performances of the two generators, we examine another nonstationary task - target capturing. The simulation result of this task agrees with the result of our previous study. From the view of multi-agent system, it is an inhomogeneous or heterogeneous system composed of some kinds of agents in many cases. In such situations, the exploration of them is not uniform. Chaotic exploration may suit well this heterogeneity in such a multi-agent system.

Modified Generalized Discriminant Analysis Using Kernel Gram-Schmidt Orthogonalization in Difference Space for Face Recognition
Authors: Yunhui He
Venue: Proceedings of the 2009 Second International Workshop on Knowledge Discovery and Data Mining (2009)

In this paper, we propose an efficient method to compute the optimal discriminant vectors of Generalized Discriminant Analysis (GDA) for face recognition tasks. The optimal discriminative features of face images are obtained by directly performing the kernel Gram-Schmidt orthogonalization procedure on the difference vectors only once. The theoretical justification is presented. The nonlinear difference vectors are first expressed using data matrix and two transformation matrices. Then, the Cholesky decomposition is performed on a kernel matrix which is obtained using data matrix and two transformation matrices. Since the proposed method does not apply the singular value decomposition as does in the traditional GDA, the high numerical stability is achieved. Moreover, because there is no need to compute the mean of classes and the mean of total samples in the proposed method, the computational complexity is reduced greatly. The effectiveness of the proposed method is verified in the experiments on two standard face databases.
Model-based signature verification with rotation invariant features
Authors: Jing Wen, Bin Fang, Y. Y. Tang, TaiPing Zhang
Venue: Pattern Recognition (2009)

Non-linear rotation of signature patterns is one of the major difficulties to solve in off-line signature verification. This paper presents two models utilizing rotation invariant structure features to tackle the problem. In principle, the elaborately extracted ring-peripheral features are able to describe internal and external structure changes of signatures periodically. In order to evaluate match score quantitatively, discrete fast fourier transform is employed to eliminate phase shift and verification is conducted based on a distance model. In addition, the ring-hidden Markov model (HMM) is constructed to directly evaluate similar between test signature and training samples. With respect to the side effect of outlier training samples for stable statistical model and threshold estimation, we propose a selection strategy to improve the performance of system. Experimental results demonstrated that the proposed methods were effective to improve verification accuracy.
Simple and efficient scheduling scheme in sensor networks
Authors: Ensaf A. Alzurqa, Hesham N. Elmahdy, Gamal Darwish
Venue: Proceedings of the 8th conference on Applied informatics and communications (2008)

The design of data communication protocols in wireless sensor networks often take into account real-time delivery of reports of the mission critical applications. The sensed data need to be delivered with some real-time constraints, such as end-to-end deadlines. Since the data communication model is different from the traditional wireless ad hoc networks or any centralized systems, different solutions have been proposed, such as real-time sensitive routing protocols, data packet prioritization, and real-time scheduling. Most of these solutions prioritize packets at the MAC layer according to their deadlines and distances to the sink. Packet prioritization by itself cannot completely support real-time data communication requirements. In our work, we develop Simple and Efficient Scheduling Scheme in Sensor Networks (SES-SN), in which packet scheduling, queuing as well as routing are considered. This scheme efficiently utilizes the limited energy and available memory resources of sensor nodes and also has a significant impact on the success of real-time sensor data communication and avoids collision.
