The overall target of the Swiss Energy Policy is to reduce CO2-emissions and thereby to achieve the vision of an energy-efficient ‘2000 Watt per Capita Society’. A major instrument to contribute to the vision in the residential building sector is standards about energyefficient building designs. However, new residual houses according to the energy-efficiency standard are not as often constructe...

This paper concerns the problem of output consensus in nonlinear non-minimum phase systems. The main contribution of the paper is to guarantee achieving consensus in the presence of unstable zero dynamics. To achieve this goal, an output redefinition method is proposed. The new outputs of agents are functions of original outputs and internal states and defined such that the dynamics of agents a...

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...

health systems research aims to understand the governance of health systems (i.e. how health systems function and perform and how their actors interact with each other). this can be achieved by applying innovative methodologies and concepts that are going to capture the complexity and dynamics of health systems when they are affected by shocks. the capacity of health systems to adapt to shocks ...

This commentary addresses two points raised by Kitson and colleagues’ article. First, increasing interest in applying the Complexity Theory lens in healthcare needs further systematic work to create some commonality between concepts used. Second, our need to adopt a better understanding of how these systems organise so we can change the systems overall behaviour, creates a paradox. We seek to m...

Water resources simulation is efficient tools to evaluate different options and decision in development conditions. Supply of water demand with high reliability need to exact and perfect planning. So, dam behavior recognition and it operation is from essentials of water resources systems management and future planning. In this study, the software VENSIM the method based on the dynamics of the s...
