Multi-component machining systems are being used in every sphere of engineering sector such as job shops, flow lines, communication system, computer system, etc. This paper presents fuzzy analysis of availability characteristics of machining system comprising of multiactive units and multi-standby units. The Markov machine repair model has been developed by incorporating the concepts of switchi...

1. In peripheral arterial insufficiency, leg blood flow during exercise is reduced. The aim of this study was to investigate the metabolic response in different muscle types during exercise at reduced versus normal exercise blood flow. 2. A modified rat hindlimb perfusion model was used. Muscle metabolites and distribution of labelled microspheres were analysed in the soleus and the gastrocnemi...

The response of the living tissue to the effects of strong heating or cooling can cause the blood flow rate to vary by an order of magnitude. A mathematical model for the freezing of living tissue is formulated which takes into account the nonlocal temperature dependence of the blood flow rate when the temperature distribution in the tissue is substantially nonuniform, as in cryosurgery. INTROD...

The recent penetration of renewable sources in the energy system caused a transformation of the needs of the distribution system and amplified the need of energy storage systems to properly balance the electricity grid. Among electrochemical energy storage devices, all vanadium flow batteries are those of the most promising technologies due to their high efficiency, long lifetime, reliability a...

The problem of finding the source distribution for particles (or radiation) in a bounded domain D from the emitting flow through the boundary of D is considered. The particles are supposed to move with unit velocity along geodesics of a Riemannian metric and can be absorbed by the medium. The metric and the absorption are known. Uniqueness of the solution to this problem and a stability estimat...

We prove that for closed surfaces M with Riemannian metrics without conjugate points and genus ?2 the geodesic flow on unit tangent bundle T1M has a unique measure of maximal entropy. Furthermore, this is fully supported T1M, limiting distribution orbits, mixing respect to measure. formulate conditions under which result extends higher dimensions.

Introduction: Lava flow surface morphology results from processes that occur during emplacement. Features such as tumuli and lava rises are indicators of flow inflation [1]. Tumuli in particular have been identified as possible indicators of lava tube location [2-5], indicating that their distribution on the surface of a lava flow is a function of the internal pathways of lava present during fl...

A noninvasive dynamic method for the measurement of blood flow, using 15O-labeled water and positron emission tomography, has been developed and used to study 20 patients with breast carcinoma. The mean tumor flow was 29.8 +/- 17.0 (SE) ml/dl/min of tissue, while normal breast flow was 5.6 +/- 1.4 ml/dl/min of tissue. The exchanging water space of tissue known as the volume of distribution of t...
