Several MANET characteristics that distinguish MANET from other wireless networks and makes routing a challenging task. This paper presents a novel clustering algorithm, which uses both internal and external factors of node in mobile ad hoc network. In Cluster based MANET routing scheme, various mobile nodes are formed as clusters. Each cluster has its own cluster head, which is having more res...
Movement is fundamental to individual and population dynamics, as it allows individuals to meet their basic requirements. Although movement patterns reflect interactions between internal and external factors, only few studies have examined the effects of these factors on movement simultaneously, and they generally focused on particular biological contexts (e.g. dispersal, foraging). However, th...
There has been tremendous growth in electronic commerce over the past few years. This growth is expected to sustain momentum in the future. Hence, the Internet has become an essential tool for business and customers. However, unlike traditional retailers, it lacks key aspects of a shopping experience like interacting with customer sales people and being physically in a store. A well-designed us...
Blood coagulation factors V and VIII each serve cofactor functions with different vitamin K-dependent serine proteases of the coagulation cascade. Physical, physiologic, and kinetic data suggest analogous structures and functions for these two proteins. Proteolytically activated factor V (factor Va) is required for the efficient production of thrombin from prothrombin by factor Xa. Similarly, a...

On the one hand, researchers have studied factors that influence collaboration and on the other, researchers have proposed models of collaborative problem solving. However, we have not found research on the relation between these factors and the dimensions used in order to describe the collaborative activity within the models. This article’s goal is to propose such relations for a situation of ...
CONTEXT Shortfalls in the US physician workforce are anticipated as the population ages and medical students' interest in careers in internal medicine (IM) has declined (particularly general IM, the primary specialty serving older adults). The factors influencing current students' career choices regarding IM are unclear. OBJECTIVES To describe medical students' career decision making regardin...
In order to improve the measurement accuracy of the linear CCD in the intersection of vertical target measurement system, the calibration model of linear CCD’s internal parameters is established and the various factors that affect the accuracy in the calibration process are analyzed. Making use of the linear CCD imaging optical principle, the optical center and the effective focal length are ca...
Although homeostatic mechanisms remain of utmost importance, rhythmic changes are present also. The main ones have a period of 24 h (circadian) or about 2-3 h (ultradian). Circadian rhythms are derived from a body clock, found in the base of the brain, and from the pattern of our sleep wake cycle, including activity and meal times. These rhythms promote the regular changes between an active wak...
