Background: Despite the irreplaceable role of cyberspace in the behaviors of modern society and the importance of observing ethics in it, so far no research has been presented to build a model of practical ethics in this space. The present study examines how ethical laws are enacted in cyberspace. Conclusion: By descriptive analysis of the concept of ethics in cyberspace, the perception is tha...

There is considerable evidence to support the hypothesis of relationship between paradoxical sleep (PS) and learning–memory processing. It has been suggested that PS is important in memory retention at the specific time course called PS windows (PSW). The time of PSWs occurrence and duration of these PSWs following the training sessions and, the neurochemical nature of PSWs has not been well kn...

Introduction: During the last decades, simulation of radiation therapy treatment conditions in treatment room for studying with more details in comparison with treatment planning system (TPS) is taken into consideration. The most problem with starting these kind of researches is the geometry of Medical linacs and verification of the accelerators. Therefore, researchers tried to...

The log-polar image geometry, first introduced to model the space-variant topology of the human retina receptors in relation to the data compression it achieves, has become popular in the active vision community for the important algorithmic benefits it provides. Despite these advantages, foveated sensing has not been widely used due to the lack of specific image processing tools. We demonstrat...

Today for the expedition of the identification and timely correction of process deviations, it is necessary to use advanced techniques to minimize the costs of production of defective products. In this way control charts as one of the important tools for the statistical process control in combination with modern tools such as artificial neural networks have been used. The artificial neural netw...
