<italic>Virtual environment (VE) technologies have considerable potential to extend the power of information visualization methods, and those of scientific visualization more broadly. Our specific focus here is on VE technologies as a medium for geographic visualization and on some of the challenges that must be addressed if the potential of VE is to be(More)
Most work with geospatial data, whether for scientific analysis, urban and environmental planning, or business decision making is carried out by groups. In contrast, geographic visualization environments and related geographic information technologies have been built and assessed only for use by individuals. In this paper, we describe a prototype(More)
Ligand-mediated endocytosis is a key autoregulatory mechanism governing the duration and intensity of signals emanating from cell surface receptors. Due to the mechanistic complexity of endocytosis and its emerging relevance in disease, simple methods capable of tracking this dynamic process in cells have become increasingly desirable. We have developed a(More)
This paper presents work exploring the potential of virtual reality (VR) within an affordable environment in the early years of architectural education has been limited. Through an immersive environment system in the studio, students create space by manipulating solids and voids while evaluating the anthropometric relations of the proposed solution. The(More)
Mechanical analyses of sediments are studied by comparison with other analyses. Both graphical and numerical methods of comparison are in use, each kind having its limitations. Two terms of a Gram-Charlier series, expressed in Krumbein's phi units, represent the data in many types of analyses, thus enabling them to be reduced to three numerical values or(More)
Four objectives of quantitative study of sediments are outlined, each of which requires specially collected samples. The corresponding techniques of collection are here called engineering sampling, descriptive sampling, environmental sampling, and correlation sampling, according to the purpose of the samples. The steps in the systematic collection of(More)
