introduction: a comparision of cytogenetic methods in the evaluation of occupationally received radiation dose by medical radiation workwrs and a study of adaptive response to subsequent higher radiation exposure in this group.the purpose of this research was to study the effects of two cryoprotectants on viability, motility, morphology and fertilization rate of mouse sperm after freezing-thawi...

Adaptive learning is an educational method which uses computers as interactive teaching devices. Computers adapt the presentation of educational material according to students' weaknesses, as indicated by their responses to questions. The motivation is to allow electronic education to incorporate the value of the interactivity afforded to a student by an actual human teacher or tutor. The techn...

the error of inertial navigation systems increase versus time, therefore for achieving higher accuracy specially in long time navigations we have to use an aiding system. global positioning system is the best aiding system in this case. in this paper we first simulate a gps and ins; then simulate tightly integration and finally review adaptation method of kalman filtering a fuzzy adaptive kalma...

Slope stability analysis is an enduring research topic in the engineering and academic sectors. Accurate prediction of the factor of safety (FOS) of slopes, their stability, and their performance is not an easy task. In this work, the adaptive neuro-fuzzy inference system (ANFIS) was utilized to build an estimation model for the prediction of FOS. Three ANFIS models were implemented including g...

Laser materials processing (LMP) is highly sensitive to small disturbances in the process inputs, resulting changes thermal dynamics, particularly, peak temperature and cooling rate. These dynamic turn vary consistency of material mechanical properties processed material. There are numerous models estimate control these dynamics LMP processes. However, none existing can deal with real-time. In ...

When adversity strikes, when mental and physical functioning and health are at risk, humans ‘fight back’. Humans come with and develop a set of adaptive processes that gives them the potential to fend off disaster, to reshape challenges and to transform stressful experiences into psychological growth. Coping describes some of these adaptive processes (Coelho et al., 1974; White, 1974). Research...

The use of 3D (3 Dimensional) Virtual Environments is gaining interest in the context of academic discussions on E-learning technologies, as it provides several advantages over classical learning material. However, the use of 3D for learning environments also has drawbacks, especially usability and the effectiveness may cause problems. One way to overcome these drawbacks is by providing an adap...

A way to improve the effectiveness in e-learning is to offer the personalized approach to the learner. Adaptive e-learning system needs to use different strategies and technologies to predict and recommend the most likely preferred options for further learning material. This can be achieved by recommending and adapting the appearance of hyperlinks or simply by recommending actions and resources...
