Many of the physical phenomena, like friction, backlash, drag, and etc., which appear in mechanical systems are inherently nonlinear and have destructive effects on the control systems behavior. Generally, they are modeled by hard nonlinearities. In this paper, two different methods are proposed to cope with the effects of hard nonlinearities which exist in friction various models. Simple inver...
This article indicates how competition between afferent data and learned feedback expectancies can stabilize a developing code by buffering committed populations of detectors against continual erosion by new environmental demands. The gating phenomena that result lead to dynamically maintained critical periods, and to attentional phenomena such as overshadowing in the adult. The functional unit...
the present paper deals with criminal issues. for example, legal injunction on the necessity of returning a deposit has a legal nature and legal injunction on the punishment of those who breach the trust has a criminal nature. existing social issues are the basis of classification of some instances into the issue, some of which are based on variation and others on quality. therefore, the motiva...
Complexity and conflict are some of the strategies to increase visual diversity, which is less considered today in the context of extensive construction and adherence to the universal, inclusive model. This issue has led to long-term boredom in contemporary homes. However, the factors of contradiction and complexity are seen in the visual diversity of traditional architecture. In this way, the ...
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
Environmental problems in agriculture have proven difficult to address due to the spatial heterogeneity and temporal variability intrinsic to agriculture. Agriculture is largely a struggle against nature; both its sustainability and the prospects for improving environmental performance and farm income simultaneously are thus inherently limited. Agriculture’s high degree of variability makes dir...
Successful target detection, especially if there is a similarity between the target and the background area, always is a noticeable issue in remote sensing studies. Because of the spectral behavior similarity to the other phenomena and spatial distribution of these units, the mapping of wind erosion units is difficult. Thus, this study attempts to detect the favorable areas by using matched fil...
During the few past years, there has been a growing interest in the timing and locating of moving stimuli. The most popular spatio-temporal phenomena that have been studied are the flash-lag effect (FLE) [Nature 370 (1994) 256] and the Fröhlich effect (FE) [Z. Sinnesphysiol. 54 (1923) 58]. Most often these phenomena are examined by some spatial task (e.g., judging whether moving and flashed sti...
abstract nowadays, industries cannot play a crucial role in national and international competitions. the tourism industry is no exception. tourism industry development as the most important economic sector and income generation is one of the key challenges of economic development in the world. therefore, countries were successful that take advantage of the capabilities of tourism sector using ...
