according to the changing business, nowadays teams are cornerstones of successful organizations, in addition, with the developments and technological innovations in communication and information, virtual teams are playing more critical role in today's business. on this basis, determining factors which affect virtual team's performance are important to both scholars and practitioners. ...

In the context of industrial engineering, the predetermined time systems (PTS) play an important role in workplaces because inefficiencies are found in assembly processes that require manual manipulations. In this study, an approach is proposed with the aim to analyze time and motions in a manual process using a capture motion system embedded to a virtual environment. Capture motion system trac...

At every level of the visual system - from retina to cortex - information is encoded in the activity of large populations of cells. The populations are not uniform, but contain many different types of cells, each with its own sensitivities to visual stimuli. Understanding the roles of the cell types and how they work together to form collective representations has been a long-standing goal. Thi...

Recent advances in crowd simulation techniques have led to realistic agent and group behavior through elaborate behavioral models, complex motion planning algorithms and impressive physics systems. As many crowd simulation solutions typically target only specific types of environment and scenario, a variety of special-purpose methods and systems has emerged that are hard to re-configure and re-...

although there are many potential benefits associated with the use of virtual product development teams, exploiting these benefits requires an appropriate management. managing virtual product development team is a critical issue as many of these teams fail to accomplish their goals. review of previous literature shows that body of knowledge in managing virtual product development teams is fragm...

Aim: The purpose of this study was to examine the relationship between subjective social status (SSS) and objective socioeconomic status (SES) on sleep status (sleep duration and daytime sleepiness). Method: The study sample included 73 primary care patients from a free medical clinic in which low-income individuals are primarily treated. Subjective social status was measured using the MacArthu...
