This paper describes an animation approach with autonomous actors reacting to their environment and taking decisions based on perception systems, memory and reasoning. With such a system, we should be able to create simulations of situations such as virtual humans moving in a complex environment they may know and recognize, or playing ball games based on their visual and touching perception. In...

after the cold war and collapse of the bipolar system, the european :union: found more opportunity to play a role in regional and international arenas. on the other hand, russia was searching for a new status due to its widespread developments. changing the status of international system, emergence of new and powerful actors, expansion of the european :union: to the east and bordering with russ...

In the future, there will be an increased demand for biomass to replace energy and products of fossil origin with renewable alternatives. Such a transition requires action at both national local level. Municipalities as key actors need tools increase utilization biomass. One such tool is means assess biomass’ potential use. Consequently, this study investigated how aid “assessment potential” (A...

     It has been reported that in different regions and sowing dates, the response of crops to past climate change is not the same, due to different rates of decrease/increase in each climatic variable at different regions and months of year. This study was aimed to assess the effect of individual versus simultaneous changes in solar radiation (S), precipitation (P) and temperature (T) on rainf...

Forest ecosystems are among the largest terrestrial carbon reservoirs on our planet earth thus playing a vital role in global carbon cycle. Presently, remote sensing techniques provide proper estimates of forest biomass and quantify carbon stocks. The present study has explored Landsat-8 sensor product and evaluated its application in biomass mapping and estimation. The specific objectives were...

Due to the importance of Acer monspessulanum in Iranian mountain forests, a study was carried out to reliably estimate its woody biomass and growing volume via allometric equations. Four transects, five trees in each were chosen randomly. The characteristics of standing trees including: diameter at root collar, height, number of stems and crown width were measured, then trees were finally cut d...
