Virtual collaboration in corporations is an important factor for working efficiently without the limitations of time and place. As a business domain, product costing is characterized by a high demand for communication, coordination, and information exchange. Nevertheless, practitioners point out that product costing does not exhibit a modern tool-based collaborative practice. Thus, this paper e...

This article describes the different partnership strategies in the purchasing The paper compares the different customer-supplier relationships from the point of view of purchasing and deals with virtual companies in particular. Also, the contribution traces the architecture of the virtual organisations and analyses their advantages and disadvantages. The world of practice reveals that through t...

In order to take the developing field of Social Robotics a stage further, this work investigates mixed reality in embodied social agents. The Virtual Robotic Workbench is employed which provides a versatile framework for experimentation in interoperability and cooperation between heterogeneous robots (real, simulated and virtual) and humans in multi-reality domains. Explicit social interaction,...

1 Introduction Today, organisations and enterprises are currently facing fundamental changes such as rapidly changing markets, global competition, dynamic modifications in the economical and political environment, introduction of information technology, and worldwide availability of information. Consequently, enterprises have started to reengineer their internal structures by decreasing the siz...

Li Yunfei , Chen Chengqin School of Computer science & Technology, Soochow University, Suzhou ,Jiangsu,China [email protected] (Telephone: 086-0512-67799890) Abstract: The virtual instrument based on agent technique has such characteristics like adaptability, coordinative and learnable abilities in addition to these inherent advantages of virtual instrument. This paper introduces the architectur...

Developing and implementing software project is considered a teamwork effort that requires good collaboration and communication. Face-to-face meetings are not always feasible in some settings, such as, outsourcing, scattered stakeholders needed for requirements’ negotiating, remote quality team reviewers, etc. Designing successful virtual meeting sessions is generally a challenging task for a t...

Multiple-input multiple-output (MIMO) systems have recently emerged as one of the most significant wireless techniques, as they can greatly improve the channel capacity and link reliability of wireless communications. These benefits have encouraged extensive research on a virtual MIMO system where the transmitter has multiple antennas and each of the receivers has a single antenna. Single-anten...

We investigate the influence of the update dynamics on the evolution of cooperation. Three of the most studied games in this area are used: Prisoner’s Dilemma, Snowdrift and the Stag Hunt. Previous studies with the Prisoner’s Dilemma game reported that less cooperators survive with the asynchronous version of the game than with the synchronous one. On the other side, studies with the Snowdrift ...

We present and discuss polarimetric observations performed with the VLT–UT3 (Melipal) on the afterglow of GRB 011211, ∼ 35 hours after the burst onset. The observations yielded a 3-σ upper limit of P < 2.7%. We discuss this result in combination with the lightcurve evolution, that may show a break approximately at the time of our observation. We show that our upper limit is consistent with the ...

This chapter introduces a model which connects representations of the space surrounding a virtual humanoid’s body with the space it shares with several interaction partners. This work intends to support virtual humans (or humanoid robots) in near space interaction and is inspired by studies from cognitive neurosciences on the one hand and social interaction studies on the other hand. We present...
