In this study, the longitudinal and hoop tensile strengths of an industrial ±55° Glass Reinforced Epoxy (GRE) pipe with eighteen layers as well as the associated failure mechanisms are determined. To obtain the longitudinal and hoop tensile strengths values, three specimens are cut from the studied GRE pipe in each direction. A comparison is done between both the strength values, and the fractu...

The study of interactions of jet into cross flow at different longitudinal and transverse angles of jet was studied. The following components were designed and constructed: a low velocity wind tunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jet injection, and a spatial rake to measure the total pressure. The tests were carried out at longitudina...

the purpose of this study is to determine the effect of vierendeel panel width and vertical truss spacing ratio in an inelastic behavior of the stf system due to earthquake loads. the stf system is applied to a six-storey building that serves as apartments [2]. the stf system is used in the building in the transverse direction (n-s direction), while in the longitudinal direction (w-e direction)...

Novel feedback control which is designed in human-friendly way is applied to power assist wheelchair. It provides this three-dimensional control of a wheelchair taking the operation situation into considerations; wheelchair needs controlling in the three dimensions: the longitudinal direction, the lateral direction, and the pitch direction. To this end, three assist controls are suggested: dist...

Crystallization of Aluminum fluoride at atmospheric pressure has been considered. Structure, size and shape of crystals formed during the crystallization process have been investigated. By applying the direct analysis method for the existed aluminum in solution, the aluminum fluoride nucleation process has been detected as a concentration valley at the outset of crystallization process. The...

Assessment of the reservoir structure and determination of theinsitu stress direction arenecessary in oil production optimization andfield development. Today, the application of reservoir software and Image logsplay a central role in resolving this problem. Electricand ultrasonic imaging tools record vast amounts of high-resolution data within the borehole wall. This enables the geoscientists t...

We measured the conduction characteristics at the epicardial surface of the left anterior ventricular wall in the in situ canine heart before and 3 to 5 days (n = 9 dogs) after permanent occlusion of the left anterior descending coronary artery (LAD). During ventricular stimulation generating wavefronts conducted along the longitudinal or the transverse fiber direction, 61 unipolar electrograms...

thermomechanical control process steel produced by rolling has a significant anisotropy. the elongated grains and inclusions formed during hot rolling of ferrite and low carbon hsla steels directly influence the anisotropy of the steel’s mechanical properties as a result of microstructural anisotropy. the present research deals with this anisotropy, and particular attention has been paid to the...
