A new mathematical model based on the alternative process routings in presence of a queuing system in a dynamic cellular manufacturing system has been proposed in this paper.This model integrates two problems of cell formation and inter-cell layout and also an efficiency factor which is defined for minimizing the cell load variation through the maximizing the busy time for all machine types. In...

The spatial layout of images plays a critical role in natural scene analysis. Despite previous work, e.g., spatial pyramid matching, how to design optimal spatial layout for scene classification remains an open problem due to the large variations of scene categories. This paper presents a novel image representation method, with the objective to characterize the image layout by various patterns,...

| This paper presents a fast and eecient algorithm to estimate the area cost of a given RTL datapath. This is achieved by considering the physical length of components (provided by a component library) and connections data (given by the datapath description) within an actual layout model and using analytical formulas in a constructive algorithm. Our layout estimator uses a non-probabilistic bas...

WebTV is a device which enables access to the Internet using a TV set rather than a conventional computer. User interaction is typically supported by a remote control. This results in a discrete approach to intra-page navigation, which yields specific requirements on page layout. We analyze the factors of page layout that may hurdle discrete navigation of web pages, and we propose a metric supp...

Our recent study of a nation-wide production network uncovered a community structure, namely how firms are connected by supplier-customer links into tightly-knit groups with high density in intra-groups and with lower connectivity in inter-groups. Here we propose a method to visualize the community structure by a graph layout based on a physical analogy. The layout can be calculated in a practi...
