Due to the flexibility and ease of control, unmanned aerial vehicles (UAVs) have been increasingly used in various scenarios applications recent years. Training UAVs with reinforcement learning (RL) for a specific task is often expensive terms time computation. However, it known that main effort process made fit low-level physical dynamics systems instead high-level itself. In this paper, we st...

This research has been conducted by the aim of analysis of the relation of inefficient Attitude and social undermining of the employees of football clubs in Kerman. The research method is descriptive-correlative. The statistical population of this research includes all employees of teenage, youth and adult employees of Kerman city in 2017 with the total number of 192 from which 153 replied to t...

An extensive literature identifies how rational people who observe the behavior of other privately-informed rational people with similar tastes may come to imitate them. While most of the literature explores when and how such imitation leads to inefficient information aggregation, this paper instead explores the behavior of fully rational observational learners. In virtually any setting, they i...

Actions are usually generalized among social group members. Importantly, the efficiency of an action with respect to achieving external target determines understanding, and it may have different degrees relevance groups. Thus, this study explored role in generalization. We used computer animations simulate actions groups initiated by visual cues or category labels, we measured differences respo...

in this work we deal with actions of vector groupoid which is a new concept in the literature‎. ‎after we give the definition of the action of a vector groupoid on a vector space‎, ‎we obtain some results related to actions of vector groupoids‎. ‎we also apply some characterizations of the category and groupoid theory to vector groupoids‎. ‎as the second part of the work‎, ‎we define the notion...

This paper proposes a theory of optimal public expenditure when unemployment is inefficient. The theory is based on a matching model. Optimal public expenditure deviates from the Samuelson rule to reduce the unemployment gap (the gap between the current and efficient rates of unemployment). Such optimal “stimulus spending” is described by a formula expressed with estimable sufficient statistics...

This paper presents ChronoTape, a tangible timeline for family history, as an example of ‘slow technology’. We discuss how the experience of using ChronoTape has led us to believe that successful slow technology is designed to be inefficient but resilient. Author
