This paper presents a new algorithm for real-time tracking of pairs of closest points as well as their corresponding surface features between certain general types of objects (which can be non-convex) with parametric curved surfaces. The fact that the algorithm works directly on accurate parametric descriptions of curved surfaces rather than polygonal approximation of surfaces (i.e., polygonal ...

Solar farm suitability in remote areas will involve a multi-criteria evaluation (MCE) process, particularly well suited for the geographic information system (GIS) environment. Photovoltaic (PV) solar farm criteria were evaluated for an island-based case region having complex topographic and regulatory criteria, along with high demand for low-carbon local electricity production: Ulleung Island,...

In this article, we defend the thesis that geographical proximity remains essential for knowledge transfer, but not often implies the co-location of innovation and research activities. The need for geographical proximity now mostly affects certain stages of the process of production, research or development. Short or medium-term visits are often sufficient for the partners to exchange the infor...

History, geography, environment, and technology influence the cultural practices and institutions of a society and vice versa. But how strongly do geography, environment, and technology correlate with culture and institutions? To add insight into this question, we use a new methodology which explores the relationship between a variety of bilateral proximity measures developed using the societie...
