The concept of logic entropy on D-posets
In this paper, a new invariant called {it logic entropy} for dynamical systems on a D-poset is introduced. Also, the {it conditional logical entropy} is defined and then some of its properties are studied. The invariance of the {it logic entropy} of a system under isomorphism is proved. At the end, the notion of an $ m $-generator of a dynamical system is introduced and a version of the Kolm...
متن کاملAn efficient maximum entropy technique for 2-D isotropic random fields
In this paper, we present a new linear MEM algorithm for 2-D isotropic random fields. Our procedure differs from previous 2-D MEM algorithms by the fact that we take maximal advantage of the symmetries implied by isotropy, which is the natural generalization to several dimensions of the l-D notion of stationarity. Unlike general 2-D covariances, isotropic covariance functions which are positive...
متن کاملImproved Genetic Algorithm Based 2-D Maximum Entropy Image Segmentation Algorithm
Since simple genetic algorithm based 2-D maximum entropy image segmentation algorithm has the problem of premature, this paper proposes an improved genetic algorithm. Through using Fitness Extreme Distance (FED), the improved genetic algorithm proposed in this paper establishes fuzzy evaluation mechanism in the evolution procedure. Compared with the simple genetic algorithm, improved algorithm ...
متن کاملInfrared image segmentation with 2-D maximum entropy method based on particle swarm optimization (PSO)
The 2-D maximum entropy method not only considers the distribution of the gray information, but also takes advantage of the spatial neighbor information with using the 2-D histogram of the image. As a global threshold method, it often gets ideal segmentation results even when the image s signal noise ratio (SNR) is low. However, its time-consuming computation is often an obstacle in real time a...
متن کاملBUPROPION-INDUCE D CLIMBING THROU GH D -1 AND D-2 DOPAMINE RECEPTOR ACTIVATION
Intraperitoneal (IP) injection of bupropion (3,6, amine (4,16 mg kg•') induced dose-dependent climbing in mice. The climbing response induced by both drugs were decreased in animals pretreated either with the 0-1 antagonist SCH 233<)0 or the 0-2 antagonist sulpiride. The α-adrenoceptor blocker phenoxybenzamine decreased the climbing induced by both bupropion and amphetamine, but the β-ad...
