This paper introduces how geographically distributed virtual prototyping, a new Internet technology, can be designed to facilitate designer-customer communication in product development of small electronic devices, such as mobile telephones. The research approach to understand how cooperative work happens in conceptual design is discussed with an example of requirements focusing on communicatio...

The tradeoff between performance and scalability is a fundamental issue in distributed sensor networks. In this paper, we propose a novel scheme to efficiently organize and utilize network resources for target localization. Motivated by the essential role of geographic proximity in sensing, sensors are organized into geographically local collaborative groups. In a target tracking context, we pr...

A partially distributed team (PDT) consists of two or more subteams that are separated geographically. In a PDT, members of a given subteam are co-located, but they collaborate with members of geographically distant subteams. PDTs are commonplace across diverse IT settings, including outsourcing, off-shoring, and distributed organizations. Often the distance separating subteams spans multiple t...

The concept of coupling geographically distributed (high-end) resources for solving large-scale problems is becoming increasingly popular, forming what is popularly called grid computing. The management of resources in the grid environment becomes complex as they are (geographically) distributed, heterogeneous in nature, owned by different individuals/organizations each having their own resourc...

Web applications have evolved from serving static content to dynamically generating Web pages. Web 2.0 applications include JavaScript and AJAX technologies that manage increasingly complex interactions between the client and the Web server. Traditional benchmarks rely on browser emulators that mimic the basic network functionality of real Web browsers but cannot emulate the more complex intera...

Recent investigations reveal an important new class of transient radio phenomena that occur on submillisecond timescales. Often transient surveys’ data volumes are too large to archive exhaustively. Instead, an on-line automatic system must excise impulsive interference and detect candidate events in real-time. This work presents a case study using data from multiple geographically distributed ...

We show that autocatalytic networks of -machines and their population dynamics differ substantially between spatial (geographically distributed) and nonspatial (panmixia) populations. Generally, regions of spacetime-invariant autocatalytic networks—or domains—emerge in geographically distributed populations. These are separated by functional membranes of complementary -machines that actively tr...

Open Source Software development often resembles Agile models. In this paper, we report about our experience in using SCRUM for the development of an Open Source Software Java tool. With this work, we aim at answering the following research questions: 1) is it possible to switch successfully to the SCRUM methodology in an ongoing Open Source Software development process? 2) is it possible to ap...

As the number of users of cloud services increase all over the world, cloud service providers keep deploying geographically distributed data centers more. Since resource capacity of a data center is limited, cloud service providers need to distribute load to data centers. However, when the provider distributes load, SLAs (service level agreements) established with consumers should be guaranteed...

Grid Computing is a collection of computing and storage resources that are collected from multiple administrative domains. Grid resources can be applied to reach a common goal. Since computational grids enable the sharing and aggregation of a wide variety of geographically distributed computational resources, an effective task scheduling is vital for managing the tasks. Efficient scheduling alg...
