the problem of relative motion control for spacecraft formation flying in eccentric orbits is considered in this paper. due to the presence of nonlinear dynamics and external disturbances, a robust fuzzy sliding mode controller is developed. the slopes of sliding surfaces of the conventional sliding mode controller are tuned according to error states using a fuzzy logic and reach the pre-define...

the permian deposits in the stratigraphic section of sangsar (located in the eastern alborz), are the best expose in the semnan area. this sequence consists of the doroud (asselian-sakmarian), ruteh (artinskian-murgabian) and nessen (early djulfian) formations. the dorud formation in the studied section with 56 m thickness consists of conglomerate, sandstone and quartzite, which is disconformit...

We prove that for generic network-formation games where players incur a strictly positive cost to propose links the number of Nash equilibria is finite. Furthermore all Nash equilibria are regular and, therefore, stable sets.

Biochemistry courses at Seattle University have been taught exclusively using process oriented guided inquiry learning (POGIL) without any traditional lecture component since 1997. In these courses, students participate in a structured learning environment, which includes a preparatory assignment, an in-class activity, and a follow-up skill exercise. Instructor-designed learning activities prov...

This paper studies a model of dynamic network formation when individuals are farsighted : players evaluate the desirability of a “current" move in terms of its consequences on the entire discounted stream of payoffs. We define a concept of equilibrium which takes into account farsighted behavior of agents and allows for limited cooperation amongst agents. We show that an equilibrium process of ...

This paper provides a survey of recent experimental work in economics focussing on social and economic networks. The experiments consider networks of coordination and cooperation, buyer-seller networks , and network formation.

I study a network based mechanism of norm enforcement in a community where agents play a Prisoner’s Dilemma with changing partners. Agents may choose a number of close friends. Communication to close friends within the network enforces cooperation. In a world with noiseless communication, it is optimal that each agent has close contacts to all other network members. Moreover, it is optimal to h...

We have observed transverse pattern formation leading to highly regular structures in both the near and far fields when a near-resonant laser beam propagates without feedback through an atomic sodium vapor. One example is a regular far-field honeycomb pattern, which results from the transformation of the laser beam within the vapor into a stable three-lobed structure with a uniform phase distri...
