Developing elementary behavior is the starting point for the realization of complex systems. In this paper we win describe a learning algorithm that realizes a simple goal-reaching behavior for an autonomous vehicle when a-priori knowledge of the environment is not provided. The state of the system is based on information received by a visual sensor. A Q-learnlng algorithm associates the optima...

Recent studies on artificial materials demonstrate that substantial improvements in electromagnetic response can be attained by combining different materials subject to desired metrics. However, the perfect material combination is unique and extremely difficult to determine without automated synthesis schemes. In this paper, we develop a versatile approach to design the microstructure of period...

background: it is estimated that major depression disorders constitute 8.2% of years lived with disability (ylds) globally. the repetitive transcranial magnetic stimulation (rtms) and electroconvulsive therapy (ect) are two relative common interventions to treat major depressive disorders, especially for treatment resistant depression. in this study the cost- effectiveness and cost-utility of r...
