In order to cope with rapid growth of congestion levels in urban areas, it is necessary to improve performances of a traffic network which can be one of the basic tasks of transport planning. In this situation „‟build only‟‟ approach, in most cases, is not the right approach. New transport strategies on the local and political levels must be defined and all stakeholders must be identified. The ...

Numerical simulation analyzes the mixed convection flow of $$\hbox {Al}_{2}\hbox {O}_{3}{-}\hbox {Cu}{-}\hbox {H}_{2}\hbox {O}$$ (aluminium oxide–copper–water) hybrid nanofluid inside a split lid-driven trapezoidal cavity. A triangular-shaped cold obstacle is placed The horizontal base cavity kept cold, whereas side walls are chosen adiabatic. thermally active upper wall maintained at constant ...

BACKGROUND There is a paucity of reports in the literature examining the pattern of sensory and autonomic neural recovery of myocutaneous microvascular flaps and skin grafts to the lower limbs after a prolonged period of time. OBJECTIVES To investigate the recovery of sensation and autonomic nerve activity in long-standing split-skin grafts applied to fascial beds and in myocutaneous microvas...

This article is concerned with the formulation and numerical solution of equations for modelling multicomponent, two-phase, thermal fluid flow in porous media. The fluid model consists of individual chemical component (species) conservation equations, Darcy’s law for volumetric flow rates and an energy equation in terms of enthalpy. The model is closed with an equation of state and phase equili...

The engine and its exhaust flow behaviors are investigated in a turbo-charged gasoline direct injection engine under simulated cold-fast-idle condition. The metrics of interest are the exhaust sensible and chemical enthalpy flows, and the exhaust temperature, all of which affect catalyst light off time. The exhaust sensible enthalpy flow is mainly a function of combustion phasing; the exhaust c...

With the globalization of integrated circuit (IC) design flow and the outsourcing of chip fabrication service, intellectual property (IP) piracy and malicious logic insertion become main security threats to tamper hardware infrastructures. While most of the protection methods are dedicated for digital circuits, we try to protect radio-frequency (RF) designs which are more likely to be IP piracy...

A technique is developed for measuring the flow stress of metals over a broad range of strains, strain rates, and temperatures, in uniaxial compression. It utilizes a recent, enhanced version of the classical (Kolsky) compression split Hopkinson bar [l], in which a sample is subjected to a single stress pulse of a predefined profile, and then recovered without being subjected to any other addit...
