This paper presents the Eclipse-II, a new six degree-offreedom parallel mechanism, which can be used as a basis for general motion simulators. The Eclipse-II is capable of x, y and z-axis translations and a, b and c-axis rotations. In particular, it has the advantage of enabling continuous 360-degree spinning of the platform. The computational procedures for forward and inverse kinematics of th...

Abstract Oil rim reservoirs are characterised with a small thickness relative to their overlying gas caps and underlying aquifers the development these planned very carefully in order avoid water coning maximise oil production. Studies have shown low recoveries from injection, while foam alternating injections resulted positive recoveries, it is viewed that an option of application chemical enh...

Fracture reservoirs contain most of the oil reserves of the Middle East. Such reservoirs are poorly understood and recovery from fractured reservoirs is typically lower than those from conventional reservoirs. Many efforts have been made to enhance the recovery and production potential of these reservoirs. Fractured reservoirs with high matrix porosity and low matrix permeability need a seconda...

STATEMENT OF PROBLEM Mechanical properties of denture acrylic resins are important for the clinical success of multiple types of prostheses. Acrylic resins must be strong and resilient so as to withstand impact. Few studies utilize cyclic loads to characterize material response to repeated stress. PURPOSE The purpose of this study was to evaluate static and dynamic flexure properties of a var...

We report on an unusually bright observation of PSR J2051$-$0827 recorded during a regular monitoring campaign black-widow pulsar systems with the Effelsberg 100-m telescope. Through fortunate coincidence, particularly scintillation maximum is simultaneous eclipse by companion, enabling precise measurements variations in flux density, dispersion measure (DM), and scattering strength throughout ...

Microscopic oil displacement of water flooding and sweep efficiency of continuous gas injection could be improved by water alternating gas (WAG) injection. The WAG injection process aims to squeeze more oil out of the reservoirs; in this method, water and gas are alternatively injected into the reservoir. Also, availability of hydrocarbon or CO2 gases in the field makes it attractive for gas-ba...
