The main challenge in Wastewater Treatment Plants (WWTP) by activated sludge process is the reduction of the energy consumption that varies according to the pollutant load of influent. However, this energy is fundamentally used for aerators in a biological process. The modeling of energy consumption according to the decision parameters deemed necessary for good control of the active sludge ...

today’s challenge is learning about how to live with the change instead of planning for it and the critical point that causes the organizational change programs to fail is the lack of integrated conceptual model. to face this issue, the article has a literature review to develop a holographic model. in this model. content analysis has been used in this article. theresult was a holographic model...

this article presents an implementation of a reinforcement learning (rl) method for a snake like robot navigation. the paper starts with developing kinematics and dynamics model of a snake robot in serpentine locomotion followed by performing simulation and finishes with actual experimentation. first, gibbs-appell's method is used to obtain the robot dynamics. the robot is also modeled in simme...
