This paper studies the dynamics of an economic growth model with global warming. Recent research on climate change suggests that there exists a negative feedback effect from global surface temperature and the capacity of the earth to reflect radiation. Our paper takes into account that the ratio of reflected to incident radiation of the earth, i.e. the albedo, negatively depends on the average ...

Augmented reality has recently achieved a rapid growth through its applications in various industries, including education and entertainment. Despite the growing attraction of augmented reality, trend analyses in this emerging technology have relied on qualitative literature review, failing to provide comprehensive competitive intelligence analysis using objective data. Therefore, tracing indus...

T paper proposes a descriptive model of the spatial and temporal evolution of retail distribution for new packaged goods. The distribution model postulates separate processes for local market entry by manufacturers, and adoption by retailers given entry. Of special interest is whether retail adoption occurs along a competitive network with retailers as nodes and overlapping trade areas of these...

Many empirical studies of ecological community indicate the coexistence of competing species is extremely common in nature. However, many mathematical studies show that coexistence of competitive species is not so easy. In the present article, we focus on the segregation of habitat (microhabitat). If habitats of species are spatially separated, they can coexist easily: under the habitat segrega...

This paper presents a case study where competitive e-learning strategies are used in the teaching of an undergraduate Database course in order to develop, in university students, the capacity to actively research and to lead their own learning process. The experience has been carried out in the spring semester (February-June 2007) and is based on the use of the QUEST system. This tool for activ...

Nowadays, with the increasing pressure of the competitive business environment and demand for diverse products, manufacturers are force to seek for solutions that reduce production costs and rise product quality. Cellular manufacturing system (CMS), as a means to this end, has been a point of attraction to both researchers and practitioners. Limitations of cell formation problem (CFP), as one o...
