Topology optimization can be divided into continuum and discrete types, the latter being the emphasis of the present work. In the field of discrete structural topology optimization of trusses, the generation of an initial ground structure is crucial. Thus, this paper examines the generation of ground structures for generic structural domains in two and three dimensions. It compares two methods ...

Vertical Axis Wind Turbines (VAWTs) are not mature enough yet for offshore wind farms, but they offer benefits compared to conventional Horizontal (HAWTs). Higher power densities, reduced wakes, lower center of mass, and different thrust curves make VAWTs an interesting option complement existing farms. The optimization farm layouts—finding the optimal positions turbines in a park—has proven cr...

The application of Max-Min Ant System for layout and size optimization of pipe networks is described in this paper. The formulation conventionally used for pipe size optimization of networks with fixed layout is extended to account for layout and pipe size determination of the networks. This is achieved by including a new constraints regarding the reliability of the network and modifying the av...

This paper presents an overview of recent advances on modeling and layout optimization of devices and interconnects for high-performance VLSI circuit design under the deep submicron technology. First, we review a number of interconnect and driver/gate delay models, which are most useful to guide the layout optimization. Then, we summarize the available performance optimization techniques for VL...

With the fast development and utilization of underground space resource in cities, the spatial distribution of urban underground pipelines becomes more and more complex. How to efficiently utilize the latest technology, realize underground space resources' management, visualization, layout optimization and mine applications, are challenging issues in current digital city development. Taking int...
