In real-time embedded system, that must carry their own power source and cannot depends on the power outlet on the wall, apart from feasibly schedule the set of tasks, power management is also the major issue because without power the system is useless. In this paper, we propose a harvesting aware real-time scheduling algorithm with variable speed assignment scheme to set of periodic tasks aims...

As an application of mathematics to engineering problems, this paper formulates a simple optimal stopping problem to decide the opening time of harvesting farmed fishery resources that maximizes an economic objective function. A sufficient condition for unique existence of the internal optimal opening time is provided and its concrete mathematical analysis is carried out. Comparative statics of...

This paper deals with automatic analysis of Czech social media. The main goal is to propose an approach to harvest interesting messages from Twitter in Czech language with high download speed. This method uses user lists to discover potentially interesting tweets to download. It is motivated by the fact that only about 20% of Twitter users are posting informative messages, whereas the remaining...

Yield prediction before harvesting is one of the tools in order to planning food production supply in future.Yield prediction was carried out for Wheat(Triticum aestivum) using different meteorological variables with agrometeorological indices in Hamedan district during 2003-04 and 2004-05. According to correlation coefficients, standard error of estimate as well as relative deviation of predic...

Chaotic vibrations may appear in nonlinear energy harvesting systems, which can be problematic when using the recovered power, as it require an extra expenditure of to rectify voltage signal or reduce process efficiency charging battery. Both cases derail harvester’s functionality. An alternative this situation is explore chaos control stabilize system dynamics so that regular and more suitable...

The objectives in this study were to develop and test a data analysis system for calculating machine productivity from GPS-derived positional information alone. A technique was used where positions were ‘filtered’ initially to locate specific events that were independent of what actually traveled the path, then these events were combined using user-specified rules into machine functions. The sy...
