Monitoring Mis-Operating Conditions of Journal Bearings based on Modulation Signal Bispectrum Analysis of Vibration Signals
(CEST_2018, 2018-09-27)
Journal bearings are widely used to undertake a wide range of operating conditions. Under high radial load, low rotating speed and thin lubrication films, asperity collisions between the journal and the bearing surfaces ...
Theoretical Investigation of an Indirect Evaporative Air Cooling System
(CEST-2018, 2018-09-27)
In this paper an indirect evaporative cooler theoretically investigated. Because of its low cost and low environment pollution, the indirect evaporative coolers have great potential as an alternative to conventional air ...
Investigations of Kaolin Clay Collapse Behavior Using an Oedometer Apparatus
(CEST-2018CE, 2018-09-20)
Geotechnical engineers face serious problems when construction sites contain collapsible soils, which are known by their strength when dry and experience sudden excessive settlement when inundated. Response-to-wetting ...
Aerodynamic Effects of Blade Positive Sweep in Axial Flow Cascades
(CEST-2018, 2018-09-27)
In this work, the effects of sweep applied to rotor of axial flow turbomachines were investigated by means of applying computational fluid dynamics (CFD) tools. Low-aspect-ratio rotors of positive sweep (PSW) have been ...
Design Of Reinforced Concrete Beams Using Two different Specification
(CEST-2018, 2018-09-27)
Nowadays, reinforced concrete beams are designed using traditional specification, such as BS8110 and Eurocode2 based on truss action. In this research BS8110 and Eurocode2 specification of designing a beam for flexure ...
Nonlinear Structural Dynamic Response of Multi-Story Buildings Under Seismic Loading
(CEST-2018, 2018-09-27)
A study of earthquakes in the world is performed, and also a study of methods of dynamic analysis suitable for use with linear and nonlinear systems is made with a stress on the nonlinear response of buildings due to ...
كيفية الاستفادة من مخلفات الخرسانة في حالتها الطازجة
(CEST-2018, 2018-09-27)
جزء كبير من الخرسانة في حالتها الطازجة والزائدة عن الكميات الفعلية المراد صبها تتحول إلى مخلفات صلدة مما يترتب عليه تكلفة عالية لإعادة تدويرها في هذه الحالة، وإذ تعتبر الخرسانة ثاني أكثر مادة استهلاكاً بعد الماء عليه فمن ...
Static and Dynamic Analysis of Multistory RC Building with Various Heights in High Seismic Zone
(CEST-2018, 2018-09-27)
The earthquake ranks as one of the most destructive natural disasters recorded all over the world. It has taken millions of lives and caused vast damages to infrastructures through the ages. Since the earthquake forces are ...
Influence of Surface Roughness on Adhesion Between the Existing and New Plain Concretes
(CEST-2018, 2018-09-27)
The bonding that exists between the old concrete and the new concrete depends largely on the quality of substrate surface preparation. The accurate representation of substrate surface roughness can help determine very ...
