An Improved Analytical Model For Wormhole Routed Networks With Application To Butterfly Fat-Trees, Ronald I. Greenberg, Lee Guan

Ronald Greenberg

A performance model for wormhole routed interconnection networks is presented and applied to the butterfly fat-tree network. Experimental results agree very closely over a wide range of load rate. Novel aspects of the model, leading to accurate and simple performance predictions, include (1) use of multiple-server queues, and (2) a general method of correcting queuing results based on Poisson arrivals to apply to wormhole routing. These ideas can also be applied to other networks.

Swarm Engineering, S. Kazadi '90

Sanza Kazadi

Swarm engineering is the natural evolution of the use of swarm-based techniques in the accomplishment of high level tasks using a number of simple robots. In this approach, one seeks not to generate a class of behaviors designed to accomplish a given global goal, as is the approach typically found in mainstream robotics. Once the class of behaviors has been understood and decided upon, specific behaviors designed to accomplish this goal may be generated that will complete the desired task without any concern about whether or not the final goal will actually be completed. As long as the generated behaviors …

A Comparison Between Single And Dual Monitor Productivity And The Effects Of Window Management Styles On Performance, Alex Stegman, Chen Ling, Randa Shehab

Dr. Chen Ling

Several research studies have been published on user opinion and productivity of using dual monitor systems. These studies found that users typically enjoy using multiple monitors, but none found a strong increase in performance and productivity. Other researchers have focused on improving multiple monitor usability, but often without any statistical framework. This study compared single and dual monitor productivity measures: task time, cursor movement, and number of window switches. Additionally, window management styles (WMS) were studied in order to help designers understand user behavior better. WMS were broken into two categories, toggler and resizer, and then compared to the WMS …

The advantages of the traceability system are more obvious for products that are exported and those imported from overseas. Traceability is highly important in food management and for products with short expiry. In recent years there have been several investigations and publications on traceability systems criteria especially in the food industry in the US, Europe and Southeast Asia.

Innovation And Learning Through Knowledge Gatekeepers:A Critical Examination Of The Relationship Betweentrust, Openness, And The Use Of Gatekeepers, Deogratias Harorimana Dr

Dr Deogratias Harorimana

The term ‘gatekeeper’ is widely used to represent a class of those who collect information, knowledge and contextualise this before they can share with the rest of the members of the organisation knowledge networks-both formal and informal organisations. In this study, it was found:

1 that there is a strong relationship between the openness of a given firm, as regards its knowledge sharing culture and level trust, and that firm’s use of knowledge gatekeepers

2 that the stage of a given firm’s growth corresponds to its strategic use of different types of gatekeeping.

In early and decline (renewal) stages, for …

Engineering Innovative Mobile Data Services: Developing A Model For Value Network Analysis And Design, Mutaz M. Al-Debei, Enas M. Al-Lozi, Guy Fitzgerald

Dr. Mutaz M. Al-Debei

Purpose – This study aims to analytically develop a reference model for engineering (i.e. analysis, design, development, evaluation, delivery, maintenance, modification, and management) powerful value networks capable of creating innovative mobile data services.

For building the model (i.e. the design science artifact in this research), we followed three iterations: (1) Literature Review Analysis; (2) Semi-Structured Interviews analyzed through content analysis; and (3) examination of real-life case studies. But for evaluating the model, we utilized the NTT DoCoMo’s i-mode case. Findings …

A Value-Based Approach For Explaining The Adoption Intention Of Mobile Data Services, Mutaz M. Al-Debei

Dr. Mutaz M. Al-Debei

This study aims at explaining the factors affecting the adoption intention of mobile data services from the perspective of consumers as users. In this study we focus on the value users can potentially gain from using these services. We hypothesize that if we can examine users' utilitarian, hedonic, uniqueness, epistemic and economic value, then we can explain and predict their intention to use mobile data services. Our results show that utilitarian value is according to previous studies an important adoption factor. Additionally, economic value is also important and significant. Nevertheless, it seems that in our context, hedonic, uniqueness, and epistemic …

Cfp: Handbook Of Research On Technological Applications And Innovation For Economic Development, Deogratias Harorimana Mr

Dr Deogratias Harorimana

The innovation in the 21st century goes significantly beyond the high-tech picture driven by small or large industry clusters in a specific region-typically Silicon Valley and M4Corridor. The future of innovation will lie within knowledge management and seamless technological applications. These will be supported by planned funding strategies, possibly with clients as drivers of the innovation. This view seems to be supported by the UK government “Technology and Innovation Futures” (2011); the USA government (2011), study into which leading scholars concede that the future innovation and technological applications for economic growth will include products and processes, improvements in areas such …

Adaptive Algorithms For Coverage Control And Space Partitioning In Mobile Robotic Networks, Jerome Le Ny, George J. Pappas

George J. Pappas

We consider deployment problems where a mobile robotic network must optimize its configuration in a distributed way in order to minimize a steady-state cost function that depends on the spatial distribution of certain probabilistic events of interest. Three classes of problems are discussed in detail: coverage control problems, spatial partitioning problems, and dynamic vehicle routing problems. Moreover, we assume that the event distribution is a priori unknown, and can only be progressively inferred from the observation of the location of the actual event occurrences. For each problem we present distributed stochastic gradient algorithms that optimize the performance objective. The stochastic …
