A Live Video Imaging for Multiple Users
Authors: Yoshinari Kameda, Michihiko Minoh, Hideaki Miyazaki
Venue: Proceedings of the 1999 IEEE International Conference on Multimedia Computing and Systems - Volume 02 (1999)

Many activities are held in a certain fixed space in our society. It becomes possible to participate in such activities from remote places. Video is one of the best media for this purpose, and it is important to consider how to image such activities. In this paper, we propose a new video imaging method with multiple cameras for multiple users. Dynamic situations in an activity are defined for describing an imaging rule of each user, and they are detected by processing sensor data. Concretely, the imaging rule is described by a user with camera-works linked to each dynamic situation. With this description of the imaging rules, many users can request their own favorite camera-works, while the system mediates these requests to satisfy as many users as possible. We have built a prototype system and conducted an experiment in which several users could participate in lecture.

Venue: Human Factors in Ergonomics Manufacturing (2009)

In a highly competitive market, customers' product affection is a critical factor to product success. However, understanding customers' affective needs is difficult to grasp; product design practitioners often misunderstand what customers really want. In this study we report our experience in developing and using an affective design framework that identified critical affective features customers have on products and are systematically incorporated into product design attributes. To identify key affective features such as luxuriousness, we utilized the Kansei engineering methodology. This approach consists of three steps: (1) selecting related affective features and product design attributes through a comprehensive literature survey, expert panel opinion, and focus group interviews; (2) conducting evaluation experiments; and (3) developing Kansei models using multivariate statistical analysis and analyzing critical product design attributes. To demonstrate applicability of the proposed affective design framework, 30 customers and 30 product design practitioners participated in an evaluation experiment for car crash pads, and 44 customers and 20 designers participated in an evaluation experiment for two interior room products (wallpapers and flooring materials). The evaluation experiments were conducted via systematically developed questionnaires consisting of a 7-point semantic differential scale and a 100-point magnitude estimation scale. The results of the experiments were analyzed using principal component regression and quantification theory type I method. Using the analyzed survey data, the relationship between luxuriousness and related affective features and product design attributes were identified. This relationship indicated that there was a significant difference in the perception of luxuriousness between customers and designers. Consequently, it is expected that the results of this study could provide a foundation for developing affective products. &copy; 2009 Wiley Periodicals, Inc.

Authors: Joy Jiang, Claudio DeSanti
Venue: Proceedings of the 2008 International Conference on Advanced Infocomm Technology (2008)

Consolidation of the multiple traffic types present in current data centers over a single unified network is a big trend in the information technology industry. Extensions to 10G Ethernet are making it the most promising technology for achieving I/O consolidation. The emerging Fibre Channel over Ethernet (FCoE) protocol plays a critical role in this convergence process. This paper elaborates how FCoE leverages the ubiquity and economics of Ethernet networks while preserving the infrastructure, strengths, and tools of the existing Fibre Channel Storage Area Network (SAN) framework.

Authors: Samaneh Khakbaz, Mahmood Fathy
Venue: Proceedings of the 2008 The Second International Conference on Next Generation Mobile Applications, Services, and Technologies (2008)

Many of applications in Vehicular Ad Hoc Networks (VANET) are based on dissemination of information, so broadcasting is one of the fundamental services in these networks. Most of applications in VANET, especially safety applications, require broadcasting of messages with high reliability in different node densities. In this paper we propose a new broadcast method, which assures broadcasting of message to back and forward directions. To analyzes its performance, it has been evaluated by network Simulator (NS2). Simulation results show, this method has high reliability to deliver message in both directions, especially in low node densities.

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

With the Industrialization of MIM technology, it is urgent to resolve the waste of energy problem, which is caused by the parts’ repeated heating in degreasing, sintering segment. So, it is proposed that by the use of the continuously sintering furnace to make the traditional single process (such as degreasing process, sintering process and post-processing, etc.) merge into the integrated process; designed the sintering furnace motion control system by S7-200 PLC (Programmable Logical Controller). And then, introduced the structural design and the control system design of the sintering furnace in detail. The successful development of the continuously sintering furnace will significantly reduce the various uncertain factors during the produce process, which will help improve the quality of forming parts and production rate.
Strategic IT planning as change specification
Authors: William S. Shu
Venue: Proceedings of the 2nd International Conference on Theory and Practice of Electronic Governance (2008)

Prioritising strategic plan executions and determining the most appropriate models and architectures for IT plans, as well as temporally sequencing and reconfiguring the latter for optimal solutions, can be tough without a supporting tool. This article therefore proposes a model where strategic plans are simple processes whose basic actions are events that change the states of institutional components and alter organisational structure. Therein, the strategic planning process, plan execution, and routine daily tasks are carried out, conceptually, in the same manner. Furthermore, the plans themselves may be reconfigured or modified according to changing organisational and architectural models for IT activities. The work assumes a formal model of time that enables one to track institutional transformations over time. Hence, the model underpins IT governance issues and tool support to investigate possible future scenarios of what could happen, analyse past activities of what happened, or just perform routine duties.
A role-oriented BDI framework for real-time multiagent teaming
Authors: Jinsong Leng, Jiuyong Li, Lakhmi Jain
Venue: Intelligent Decision Technologies (2008)

Multi-agent teaming is an active research field of multi-agent systems. Flexible multi-agent decision making requires effective reaction and adaption to dynamic changes under time pressure, especially in real-time and dynamic systems. The joint intension and sharedplan are two most popular theories for the teamwork of multi-agent systems. However, there is no clear guidance for designing and implementing agents' teaming. BDI (Belief, Desire, and Intension) architecture has been widely used to design multi-agent systems. In this paper, a role-based BDI framework is presented to facilitate the team level optimization problems such as competitive, cooperation and coordination problems. This BDI framework is extended on the commercial agent software development environment known as JACK Teams. The layered architecture has been used to group the agents' competitive and cooperative behaviors. In addition, we present the reinforcement learning techniques to learn different behaviors through experience. These issues have been specified and investigated within a real-time 2D simulation environment known as soccerBots.
Performance analysis of deterministically-routed bi-directional torus with non-uniform traffic distribution
Authors: S. Loucif, M. Ould-Khaoua
Venue: Future Generation Computer Systems (2009)

Existing research has most often relied on simulation and considered the uniform traffic distribution when investigating the performance properties of multicomputer networks (e.g. the torus). However, there are numerous parallel applications that generate non-uniform traffic patterns, such as hot-spot. Furthermore, much more attention has been paid to capturing the impact of non-uniform traffic on network performance, resulting in the development of a number of analytical models for predicting message latency in the presence of hot-spots in the network. For instance, analytical models have been reported for the adaptively-routed torus with uni-directional as well as bi-directional channels. However, models for the deterministically-routed torus have considered uni-directional channels only. In an effort to fill in this gap, this paper describes an analytical model for the deterministically-routed torus with bi-directional channels when subjected to hot-spot traffic. The modelling approach adopted for deterministic routing is totally different from that for adaptive routing due to the inherently different nature of the two types of routing. The validity of the model is demonstrated by comparing analytical results against those obtained through extensive simulation experiments.
Guest Editor's Introduction: How Open Source Tools Can Benefit Industry
Authors: Christof Ebert
Venue: IEEE Software (2009)

The software industry has evolved toward complex supplier-user networks that cooperate and collaborate in many ways. We rarely see the traditional way of software development in which one company handles design, production, sales, delivery, and service. Business models, engineering life cycles, distribution channels, and services have changed dramatically. A key driver in these new value networks is open source software (OSS). Worldwide companies in various industries have invested in open source. Market leaders such as Google, IBM, Microsoft, SAP, and Siemens as well as many small companies turn to OSS for multiple reasons. IEEE Software has assembled this minitheme to provide a glimpse of where OSS is heading.
The Design and Implementation of a Scheduling Mechanism of Differentiated Services Based on Priority
Authors: Pei-zhi Liu, Jia-li Miao, Sheng-qing Dai
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 02 (2009)

A scheduling mechanism of differentiated services based on priority is presented in this paper, which is used to resolve a problem of resource assigned fairly in circumstance of wireless multi-services. This scheduling mechanism contrasts with other multi-services scheduling algorithms in performance by simulation. The simulation results indicate that the scheduling mechanism can provide QoS guarantee and opportunity of sharing fairly bandwidth for different services, and it also gives attention to capacity optimization and fair factor.

Preemptive stochastic online scheduling on two uniform machines
Authors: Manzhan Gu, Xiwen Lu
Venue: Information Processing Letters (2009)

This paper addresses a stochastic online scheduling problem in which a set of independent jobs are to be processed by two uniform machines whose speeds are 1 and s(s>=1). Each job has a processing time, which is a random variable with an arbitrary distribution, and all the jobs are arriving overtime, which means that no information of the job is known in advance before its arrival. During the processing, jobs are allowed to be preempted and resumed later. The objective is to minimize the sum of expected weighted completion times. In this paper, the optimal policy, named SMPR, is designed for the single-machine preemptive stochastic scheduling problem where jobs have a common arriving time. Based on SMPR, the online approximative policy-UMPR, is devised for the preemptive stochastic online scheduling on two uniform machines. Then, UMPR is proved to have an approximation factor of 2. Furthermore, it is concluded that UMPR could not have a smaller approximation factor than 2, which means 2 is the approximation ratio of UMPR for the two-uniform-machine scheduling problem.
Empirical Analysis on the Volatility Transmission of RMB Exchange Rate Under the 2007 Subprime Crisis
Authors: Jia-ping Zhang, Ridong Hu
Venue: Proceedings of the 2009 International Conference on Computer Modeling and Simulation (2009)

Since the reform of RMB exchange rate regime in 2005, RMB exchange rate is much more flexible and volatile. The status and influence of RMB are greater with the sustained growth of Chinese economy. This paper investigates the international linkage between RMB exchange rate and other currency exchange rates, especially Asian currencies using the multivariate GARCH model. To investigate the impact of the financial crisis caused by the subprime crisis, we divide the sample into two parts: pre-crisis period and crisis period. Finally, we find that there is evidently shock transmission of RMB during the crisis and give a few concluding remarks and some suggestions for future research on volatility transmission of RMB exchange rate under empirical analysis.
Face Recognition Based on Unit-Linking PCNN Time Signature
Authors: Haiyan Li, Dan Xu, Rong Zong
Venue: Proceedings of the 2009 International Conference on Advanced Computer Control (2009)

In this paper, a novel method is proposed for face recognition based on Pulse Coupled Neural network (PCNN) time signature. In this approach, a probe face is first extracted PCNN time signature as the recognition features, which a two-dimensional image is projected to a low one-dimensional feature space and then is classified based on the known samples. An extensive experimental investigation is conducted using AT&T face database covering face recognition under controlled/ideal conditions, different illumination conditions and different facial expressions. The recognition ratio is 83.75% when only PCNN time signature, including 5 features is used as the recognition features and three exemplar images per person are available. The recognition ratio is 94.50% when the PCNN time signature is integrated with PCA feature based on Euclidean distance. The recognition ratio is 98.50% when the PCNN time signature is integrated with ICA feature based on Support Vector Machine (SVM). The simulation result demonstrates that proposed recognition method is robust due to the translation, rotation and scale invariance of PCNN time signature, insensitive to illumination and facial expressions changes as well as fast due to the low feature dimensions.
Interconnection networks: a survey and assessment
Authors: Kenneth J. Thurber
Venue: Proceedings of the May 6-10, 1974, national computer conference and exposition (1974)

As the level of complexity of digital systems increases, the problem of interconnecting subunits is receiving increasing attention. We are reaching the point where processing speed cannot be further improved through the use of faster componentry. Further speed-up of systems will most likely result from changes in the organization and structure of hardware, rather than by raw circuit improvements. Another factor increasing the complexity of systems is the arrival of cheap, powerful LSI microcomputers which allow system construction involving a plurality of processors connected together to perform a specific task. Restructurable system concepts are also very promising, but require extensive amounts of interconnective capability. Thus, bus structures are attracting considerable attention. This paper focuses on a small segment of the general bus structure problem; namely, interconnection (permutation, sorting, etc.) networks.
Stackelberg Strategies and Collusion in Network Games with Splittable Flow
Authors: Tobias Harks
Venue: Approximation and Online Algorithms: 6th International Workshop, WAOA 2008, Karlsruhe, Germany, September 18-19, 2008. Revised Papers (2009)

We study the impact of collusion in network games with splittable flow and focus on the well established price of anarchy as a measure of this impact. We first investigate symmetric load balancing games and show that the price of anarchy is bounded from above by m, where m denotes the number of coalitions. For general networks, we present an instance showing that the price of anarchy is unbounded, even in the case of two coalitions. If latencies are restricted to polynomials, we prove upper bounds on the price of anarchy for general networks, which improve upon the current best ones except for affine latencies. In light of the negative results even for two coalitions, we analyze the effectiveness of Stackelberg strategies as a means to improve the quality of Nash equilibria. We show that for a simple strategy, called SCALE, the price of anarchy reduces to 1&thinsp;+&thinsp;&alpha; for general networks and a single atomic follower. Finally, we investigate SCALE for multiple coalitional followers, general networks, and affine linear latencies. We present the first known upper bound on the price of anarchy in this case. Our bound smoothly varies between 1.5 when &alpha;=&thinsp;0 and full efficiency when &alpha;=&thinsp;1.
Qualitative Chance Discovery - Extracting competitive advantages
Authors: Chao-Fu Hong
Venue: Information Sciences: an International Journal (2009)

There are two directions in data mining research, qualitative analysis and quantitative analysis. Chance Discovery is a useful qualitative analysis method to visualize the data structure and to discover the potential future scenario. But in reality, due to tremendous amount of information, data structure may be too complex for the user to comprehend. In this paper, using Chance Discovery as a basic driving force, we proposed an innovative interactive human-computing process model to extract the data structure of a specific topic that the user is most interested in. Our model combined the strength of both qualitative analysis and quantitative analysis where Grounded theory and text mining technology were applied to sift out meaningful but small data. Experiment results showed that the visualized results generated by our model were more accurate than those obtained by Chance Discovery method. Furthermore, users can evaluate the relevant data structure generated by our model to decide on potential chances.

Venue: Journal of Computing Sciences in Colleges (2009)

A simple cryptosystem is presented that is based solely on the properties of addition. The presentation of this cryptosystem could help computer science majors understand the topic of encryption because its design can easily be explained (and justified). This cryptosystem could also be used as a programming assignment that uses bit shifting and/or bit masking operations.
Intelligent products: Agere versus Essere
Authors: Paul Valckenaers, Bart Saint Germain, Paul Verstraete, Jan Van Belle, Hadeli, Hendrik Van Brussel
Venue: Computers in Industry (2009)

The notion of an intelligent product places suitability for integration firmly on the research agenda. Indeed, this paradigm aims for coordination and integration on a scale that is unseen until today. Note that this applies particularly where it concerns the core businesses of companies. For that reason, this paper presents a novel concept, the intelligent being, as a vehicle to achieve suitability for integration. The concept is applied to intelligent product instances, intelligent product types and intelligent resources alike. The paper identifies: (1) which services and functionalities can be offered by intelligent beings, (2) what are suitable candidate intelligent beings, and what are not. The paper shows that intelligent beings can reflect a corresponding reality - a product - in its current, past and future states. It thus argues for a role of the intelligent being that is analogous to what maps contribute in navigation systems (and may become as important).
Photo-based 3D modeling of construction resources for visualization of operations simulation: case of modeling a precast fa&ccedil;ade
Authors: Fei Dai, Ming Lu
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

3D models of building components or construction resources have been largely created by computer-aided-design (CAD) or by proprietary code for virtual reality development. Such 3D modeling methods entail accurate definition of points, lines and their relationships in the spatial coordinate system. Unlike CAD modeling, the surveying technique of photogrammetry takes a completely different approach by deriving metric information about an object through measurements conducted on photographs of the object. The very basic technique of photogrammetry is effective and computationally simple. With much less efforts, digital cameras and photogrammetry software have made possible 3D reconstruction of an object in digital form (coordinates and derived geometric elements). The resultant 3D models may well satisfy application needs in construction simulation visualization. In this paper, we introduce computing algorithms of photogrammetry and present an application of modeling a precast facade in 3D based on digital pictures taken at a building site.
