Systems of coupled chaotic maps and flows arise in many situations of physical and biological interest. The aim of this paper is to analyze and to present numerical evidence for a common type of nonhyperbolic behavior in these systems: unstable dimension variability. We show that unstable periodic orbits embedded in the dynamical invariant set of such a system can typically have different numbe...

Combinations of some physically independent dimensions appear to fuse into a single perceptual attribute, whereas combinations of other dimensions leave the dimensions perceptually distinct. This apparent difference in the perceived distinctiveness of visual dimensions has previously been explained by the postulation of two types of internal representations -integral and separable. It is argued...

smp was substituted by wpc in four levels for preparing reconstituted milk. two ropy and one nonropy starter cultures was used for doogh preparation. yield stress, viscosity, consistency index and pseudoplastic behavior of doogh increased by increasing wpc content. results showed that wpc increased colloidal particles dimension and constructed a network which led to a decrease in doogh phase se...

Motion related human activity recognition using wearable sensors can potentially enable various useful daily applications. So far, most studies view it as a stand-alone mathematical classification problem without considering the physical nature of human motions. Consequently, they suffer from data dependencies and encounter the dimension disaster problem and the overfitting issue, and their mod...

Background: The coronary artery bypass grafting (CABG) is performed to completely or partially relieve the symptoms of coronary heart disease (CHD). One of the most important goals of this operation is the improvement of quality of life (QoL). The data obtained on healthrelated quality of life (HRQoL) represents the functional limitations and the alleviation of symptoms amon...

The present research was conducted to evaluate the quality of training services in maritime training centers of Khuzestan province (including DARYAYE DOOR, SERAJ DARYA and DARYA PEIMAYE GENAVE). For this purpose, SURVQUAL model was used. The research is of descriptive-field study type for which 110 trainees of maritime training centers of Khuzestan province were selected via stratified ra...
