We investigate the dynamics of beef-cattle pricing which is affected by several factors such as beef supply, demand for foreign currency, etc. The model incorporates mean-reversion to give insights into relationship be-tween supply a developed region (or country) and third world country’s hard currency. consider industry seg-mented two markets: Farmer-Local Cattle Agency (LCA) market in LCA buy...

The system dynamics applied in this research on modeling a tourist destination (area) life cycle (TALC) contributes to understanding its behavior and the way that information feedback governs use of loops, delays stocks flows. On basis, dynamic three-staged TALC model is conceptualized, with number visitors V as an indicator carrying capacities’ flow function V(t) determine stages. In first sup...

Mini and micro robots, which can swim in an underwater environment, have drawn widespread research interests because of their potential applications to the clinical drug delivery, biotechnology, manufacturing, mobile sensor networks, etc. In this paper, a prototype of microrobot based on the motion principle of living microorganisms such as E. Coli Bacteria is presented. The properties of this ...
