When processes wish to communicate, they must first establish communication. The stream mechanisms introduced in the Eighth Edition Unix system,1 which have now become part of AT&T’s Unix System V,2 provide a flexible way for processes to conduct an already-begun conversation with devices and with each other: an existing stream connection is named by a file descriptor, and the usual read, write...

a transversely isotropic half-space with axis of material symmetry perpendicular to the free surface supports a flexible circular plate. the contact area of the plate and the half-space is considered to be both frictionless and unbonded (tensionless). the foundation is affected by a vertical static axisymmetric load. detailed analysis of the interaction of these two systems is the target of thi...

This paper presents the fabrication and application of a micro-scale hybrid wicking structure in a flat polymer-based heat pipe heat spreader, which improves the heat transfer performance under high adverse acceleration. The hybrid wicking structure which enhances evaporation and condensation heat transfer under adverse acceleration consists of 100 μm high, 200 μm wide square electroplated copp...

The recent work on perception and measurement of visual motion has consistently advocated the use of a hierarchical representation and analysis. In most of the practical applications of motion perception it is absolutely necessary to be able to construct and process these hierarchical image representations in real-time. First, we discuss a simple scheme for coarse motion detection that highligh...

Abstract Based on the theory of electromagnetic field, Marine heavy oil induction heater uses principle to realize energy conversion and transfer, so as heat inlet temperature achieve purpose heating.By means induction, eddy currents are generated tubing wall under action a magnetic field. The heated pipe conducts in pipe. In this heating mode, coil is directly around supply unit pipeline ship ...

This paper shows the real situation about management of water and wastewater in Lebanon and focuses on problems related to urban water pollution released in environment. Water and wastewater infrastructures have been rebuilt since 1992. However, wastewater management still remains one of the greatest challenges facing Lebanese people, since water supply projects have been given priority over wa...

Pipe-in-Pipe (PIP) technology has been studied significantly owing to its superior performance in deep-water and high-pressure high temperature fields than conventional single pipe. The PIP system excellent track record of mitigating flow assurance problems from subsea wells through maintenance the fluid's It also applied marine environment where pipe cannot perform. However, complex interactio...
