We study fluctuations of the matrix coefficients for the quantized cat map. We consider the sum of matrix coefficients corresponding to eigenstates whose eigenphases lie in a randomly chosen window, assuming that the length of the window shrinks with Planck’s constant. We show that if the length of the window is smaller than the square root of Planck’s constant, but larger than the separation b...

In two-party democracies (e.g. US and UK) the two parties often alternate at the government almost periodically. Here, we present a very simple continuous-time model with three state variables (social welfare and size of the lobbies associated with the two parties) that explains this tendency to cyclic behavior. However, the analysis of the model shows that when the lobbies are unbalanced, much...

Abstract This paper presents a multiplierless image-cipher, with extendable 2048-bit key-space, based on 4-dimensional (4D) quantized piece-wise linear cat map (PWLCM). The PWLCM exhibits limit-cycles of 4-bit encoded integers periods greater than 10 7 . synthesis the in finite state space allows to eliminate undesirable precision effect due hardware realization. proposed image-cipher combines ...

Problem Statement: Computerized adaptive testing (CAT) is a sophisticated and efficient way of delivering examinations. In CAT, items for each examin responses to the items. In this way, the difficulty level of the test is levels with a small number of items. A number of operational testing programs have applied to any operational test in Turkey, where there are several standardized assessments...

Cat Swarm Optimization (CSO) algorithm was put forward in 2006. Despite a faster convergence speed compared with Particle Swarm Optimization (PSO) algorithm, the application of CSO is greatly limited by the drawback of "premature convergence," that is, the possibility of trapping in local optimum when dealing with nonlinear optimization problem with a large number of local extreme values. In or...

The purpose of this study was to create maps of potentially sustainable leopard cat (Prionailurus bengalensis) habitats for all of South Korea. The leopard cat, which is on the International Union for Conservation of Nature (IUCN) Red List, is the only member of the Felidae family in Korea. To create habitat potential maps, we selected various environmental factors potentially affecting the spe...

OBJECTIVE The objective was to assess whether a concurrent but independent navigation task exacerbates the effects of hearing loss on speech recognition and whether hearing loss degrades performance of the navigation task during the concurrent but independent listening task. BACKGROUND Navigation performance and speech comprehension both decrease when a driver follows hard-to-hear concurrent ...
