A two-player differential game of pollution control with uncertain initial disturbance stock is considered. In pace contemporary policy in the resource extraction industry, we initiate our research based on a model rehabilitation process which firms are required to compensate local rehabilitate polluted and dilapidated areas. Given reality that plays critical role production, cannot rigorously ...

This extended abstract reports our on-going work on how to control and ensure smoothness of traffic flows using the sliding mode control theory. The preliminary results suggest that our approach is highly promising, and more results are expected in the near future. † 1 General Increase-Decrease Flow Control Model A key issue in control of packet flows is the increasedecrease (I-D) control syste...

What constitutes a good life? Few questions are of more fundamental importance to a positive psychology. Flow research has yielded one answer, providing an understanding of experiences during which individuals are fully involved in the present moment. Viewed through the experiential lens of flow, a good life is one that is characterized by complete absorption in what one does. In this chapter, ...

In this contribution we present an intrinsic description of time-variant Port Hamiltonian systems as they appear in modeling and control theory. This formulation is based on the splitting of the state bundle and the use of appropriate covariant derivatives, which guarantees that the structure of the equations is invariant with respect to time-variant coordinate transformations. In particular, w...

During the past two years, Chinese joint-stock companies have been converting nontradable stock held by the state and state-controlled institutions, which constitute twothirds of all stock in Chinese firms, into stock that can trade on local exchanges. This ownership reform reduces direct state control over industrial enterprises. It also greatly increases the supply of stock, which threatens t...

in this paper using catastrophe theory, we investigate non-smooth changes in tehran stock exchange. stock market crashes bring not only panic among investors, but also in deeper market lead to recession and decrease in consumer's confidence. as catastrophe theory is strong tool in explaining nonlinear phenomena, by applying stochastic cusp catastrophe model we examine sudden change in tehr...

This study explores the effect of internal control weakness on investment efficiency of companies listed in Tehran Stock Exchange. The statistical population included all companies listed in Tehran Stock Exchange during the time period 2012-2015. Purposive sampling was the sampling method. Given the theoretical principles and the research literature, two hypotheses were proposed which were test...

Abstract In this paper we propose a modification to the standard forecasting, periodic order-up-tolevel inventory control approach to dealing with intermittent demand items, when the lead-time length is shorter than the average inter-demand interval. In particular, we develop an approach that relies upon the employment of separate estimates of the interdemand intervals and demand sizes, when de...
