A new characterization of nondeterministic concurrent strategies exhibits strategies as certain discrete fibrations—or equivalently presheaves—over configurations of the game. This leads to a lax functor from the bicategory of strategies to the bicategory of profunctors. The lax functor expresses how composition of strategies is obtained from that of profunctors by restricting to ‘reachable’ el...

In [5] and [7] adaptation algorithms taking in account the ”positive” feedback coupling arising in most of the active noise and vibration control systems have been proposed and analyzed. The stability of the system requires satisfaction of a positive real condition through an appropriate filtering of the regressor vector. It is shown in this note that the presence in addition of a feedback cont...

Field Editor: C. Schade Although there is evidence that regulatory focus is associated with opportunity exploitation, there is a lack of research examining its role at the early stages of opportunity recognition. The present study makes two major contributions to address this gap. First, we demonstrate that entrepreneurs' promotion focus is positively related to opportunity recognition, whereas...

Seam carving is a content-aware resizing method. Based on a seam carving approach to obtain semantic video compression, the non salient parts of the video are suppressed and the reduced sequence is encoded with H.264/AVC. To avoid a large overhead to encode the seams, the seams are regrouped together and approximated. In this paper, after the approximation, the seams are resynthesized similarly...

This paper investigates the development o f a direct neuro-active vihration control (AVC) mechanism for vibration reduction ofa flexible plate structure. A multi layer perceptron (MLP) neuro-controller is designed to characterise the ideal controller characteristic using an online adaptation and training mechanism. The effectiveness ofthe MLP neurocontroller is then verified within the AVC syst...

This paper mainly studies the main circuit topology, the working principle, modulation technique and control strategy of the STATCOM based on H-bridge. The STATCOM direct power control algorithm based on the virtual flux is used to control the AC side reactive power compensation, and in accordance with the principle of conservation of power, the DC side voltage imbalance factors are analyzed, a...
