Modeling, design and testing of the software underlying distributed robotic systems is a challenging task, especially when a large number of mobile robots and task coordination are involved. Model continuity, the ability to use the same model of a system throughout its design phases, provides an effective way to manage this development complexity and maintain consistency of the software. In thi...

In this research, hydrodynamics of the Bubble Train Flows (BTF) in circular capillaries has been investigated by Direct Numerical Simulation (DNS).The Volume of Fluid Based (VOF) interface tracking method and streamwise direction periodic boundary conditions has been applied. The results show that there exists an appropriate agreement between DNS and experimental correlation results. The re...

In this paper, sg-closed sets and sg-open sets are used to define and investigate a new class of functions. Relationships between this new class and other classes of functions are established.

vascular lesions rise from abnormalities in blood vessels or endothelial proliferation . capillary hemangiomas are formed by small capillaries surrounded by a layer of endothelial cells in a connective tissue stroma . various treatments are used for these conditions like excisional surgery , sclerotherapy, and recently laser irradiation. in this case study, we report successful treatment of int...

BACKGROUND Continuity is a fundamental tenet of primary care, and highly valued by patients; it may also improve patient outcomes and lower cost of health care. It is thus important to investigate factors that predict higher continuity. However, to date, little is known about the factors that contribute to continuity. The purpose of this study was to analyse practice, provider and patient predi...

According to the central limit theorem (CLT ), the distribution function Fn of a normalized sum n(X1 + ... + Xn) of n independent random variables X1, ..., Xn , having a common distribution with mean zero and variance σ 2 > 0, converges to the distribution function Φσ of the normal distribution with mean zero and variance σ, as n → ∞. We will write Φ for Φ1 for the case σ = 1. The densities of ...
