The large spread of the response to anthropogenic forcing simulated by state-of-the-art climate models in the Arctic is investigated. A feedback analysis framework specific to the Arctic is developed to address this issue. The feedback analysis shows that a large part of the spread of Arctic climate change is explained by the longwave feedback parameter. The large spread of the negative longwav...

Recent results show that a nonsmooth time invariant feedback control law can be used to stabilize an axi symmetric rigid body using only two control torques to the zero equilibrium This method however may require a signi cant amount of control e ort especially for initial conditions close to an equilibrium manifold In this paper we propose a modi cation of the previous control law which reduces...

Recent results show that a nonsmooth, time-invariant feedback control law can be used to stabilize an axi-symmetric rigid body using only two control torques to the zero equilibrium. This method, however, may require a signiicant amount of control eeort, especially for initial conditions close to an equilibrium manifold. In this paper we propose a modiication of the previous control law which r...

this study is a typological description of written formative feedback in an efl context in iran. twenty m.a. students of tefl participated in the study. they were required to summarize a scholarly article in each session on which the instructor would provide written corrective feedback (cf). written formative comments were extracted, coded, and categorized into various types, such as asking for...

A semi-distributed resource allocation scheme based on multihop equilibrium is proposed for OFDM-relay networks. This method aims to reduce the amount of feedback information from the relay nodes (RNs). Moreover, it utilizes radio resource by striking an efficient balance between the capacities of the BS-RN link and RN-MS link. Simulation results show that the proposed semi-distributed scheme a...

This paper reports a new four-dimensional energy-saving and emission-reduction chaotic system. The system is obtained in accordance with the complicated relationship between energy saving and emission reduction, carbon emission, economic growth, and new energy development. The dynamics behavior of the system will be analyzed by means of Lyapunov exponents and equilibrium points. Linear feedback...

We establish a nonlinear real estate model based on cobweb theory, where the demand function and supply function are quadratic. The stability conditions of the equilibrium are discussed. We demonstrate that as some parameters varied, the stability of Nash equilibrium is lost through period-doubling bifurcation. The chaotic features are justified numerically via computing maximal Lyapunov expone...

Market-based methods are an emerging paradigm for controlling large decentralized systems. We propose a bidding mechanism for allocation network resources among competing agents and analyze it under a gametheoretic perspective. We show the existence and uniqueness of a Nash equilibrium with certain pro t maximization properties. We further propose update algorithms that allow users to converge ...

We consider strongly monotone games with convex separable coupling constraints, played by dynamical agents, in a partial-decision information scenario. start designing continuous-time fully distributed feedback controllers, based on consensus and primal-dual gradient dynamics, to seek generalized Nash equilibrium networks of single-integrator agents. Our first solution adopts fixed gain, whose ...
