Conventional Instant Messaging (IM) applications and chat tools are inefficient in facilitating a conversation of a small group discussing several topics simultaneously. This paper presents an innovative IM system, Relaxed Instant Messenger (RIM), that combines a tree layout with a linear layout to support group chat. A tree layout is used to organize chat messages in a structural order, while ...

Grouping the machines and parts in a cellular manufacturing system based on similarities is known as the cell formation. This paper proposes a method for design of cell layout for a manufacturing system under dynamic demand environment for automation batch production industry. The proposed method of cell layout has two phases. In the first phase, Rank Order Clustering (ROC) was used to determin...

sheet metal components design and manufacture need a great deal of experience and know-how. strip layout design is usually done with trial and error until best design for strip layout is finally achieved. knowledge for the system is formulated from plasticity theories, experimental results, and the empirical knowledge of field experts. in this paper, an algorithm which can automatically design ...

Both the quality of the results of TEX s formula layout algorithm and the complexity of its description in the TEXbook are hard to beat The algorithm is verbally described as an imperative program with very complex control ow and complicated manipulations of the data structures representing formulae In a forthcoming textbook we describe TEX s formula layout algorithm as a functional program tra...

  This paper deals with the cellular manufacturing system (CMS) that is based on group technology concepts. CMS is defined as identifying the similar parts that are processed on the same machines and then grouping them as a cell. The most proposed models for solving CMS are focused on cell formation problem while machine layout is considered in few papers. This paper addresses a mathematical mo...
