Component technology and framework concepts are seen as the solution to typical engineering problems that emerge when building groupware. In this paper we introduce and discuss group editors as one example for the nee for component based design in the groupware application domain. We first outline the requirements for group editor applications and show how these requirements could be solved by ...

Multicriteria sequencing problems with criteria ordered according to their importance are considered. Additional precedence and group technology constraints are imposed. We introduce a notion of a priority-generating vector function and suggest general techniques that form a base for the construction of polynomial time algorithms for numerous sequencing problems including all known polynomially...

Traditionally, the information in speech signals is represented in terms of features derived from short-time Fourier analysis. In this analysis the features extracted from the magnitude of the Fourier transform (FT) are considered, ignoring the phase component. Although the significance of the FT phase was highlighted in several studies over the recent three decades, the features of the FT phas...

Cellular manufacturing (CM) has acquired an upward interest of researchers in recent era. The most important problem in designing cellular manufacturing systems is the cell formation (CF), which constructs part families with similar processing requirements and designates machines into machine cells to optimize the production process. This article presents a short research report based on hybrid...

Overweight and obesity are a major concern in young adults. Technology has been integrated into many weight loss interventions; however little is known about the use of this technology in young adults. The purpose of this study was to explore through focus group sessions the opinions of young adults on the use of technology for weight loss. A total of 17 young adults, between 18 and 25 years of...

The purpose of this paper is to extend the theory of task/technology fit by exploring the impact of different technology characteristics on performance of preference and intellective tasks in an inter-group context. The authors tested 80 participants on group performance using a 2x2 factorial design with task type and mode of collaboration as the independent variables. Structural equation model...

this study is done to define the technological contribution in the value chain of chemical industries and assess the effects of this on industrial’s value added. the value network contains 581 active firms in 5 stages and 21 groups, and date gathered with 141 questionnaires by snowball method. then the technology contribution and economic value added are defined for each stage and group. beside...

Exploratory Learning Environments (ELEs) allow learners to approach a problem in different ways; they are particularly suitable for ill-defined problems where knowledge is less structured and open-ended exploration is allowed. Moreover, multiple solutions which are equally valid are possible and a common and efficient way to convey this is by promoting and supporting students’ collaboration. Su...

Assistive technology (AT) aims at compensating for motor, sensory or cognitive functional limitations of its users. Severely disabled users typically need to rely on family and caregivers to setup and manage the technology they need to use on a daily basis. We propose a conceptual blueprint for an assistive technology micro-groupware platform for users with severe motor limitations. Stakeholder...

In this paper the Group Technology problem of grouping parts in families and machines in cells in order to convert a job shop production system to some pseudo ow shops is considered Several heuristic methods for solving Group Technology problem have been proposed in the literature in general not producing a ow shop in each cell unless a great number of extra machines is added We use known techn...
