in this paper, a simple and efficient method for modeling and solving the equations of a rotor with any number of disks, bearings and mass unbalances is presented using the assumed modes method. this model consists of a continuous shaft, arbitrary number of mass unbalances in any axial location and phase angle, and any number of rigid disks and bearings. this arrangement is extensively used in ...

Use of auxiliary elements in refining and betterment of engineering properties of soil have gained attention since a long time ago. Nowadays the effectiveness and capability of the soil reinforcing technique for giving proper practical solutions in various projects have resulted in this technique quickly gaining a place in geotechnical engineering. In this paper, the results of laboratory studi...

results the means ± standard deviations of the averaged emg during the lateral and frontal wp exercises were 40.1 ± 19.1, and 23.7 ± 11.3 µv, respectively. those of the percent maximal voluntary contraction during the lateral and frontal wp exercises were 51.4 ± 29.7, and 31.3 ± 20.5, respectively. gmax activity during the lateral wp exercise was significantly higher than that during the fronta...

abstract   statement of problem: hertzian indentation test has been proven to be an efficient and reliable alternative upon vickers hardness test. this method has been used to test dental ceramics, amalgams, glass ionomers and luting cements.there is limited published information about the load-bearing capacity of resin composites using hertizian indentation test. objectives: to investigate the...

Several deficient steel structural members require to be strengthened all over the world. In this article, horizontal defects were generated at three locations (top, middle, and bottom) on the middle element and the middle of the side element. Consequently, the effects of the location of such defects on axial behavior of Carbon Fiber Reinforced Polymer (CFRP) strengthened steel Square Hollow Se...

Spirituality........A single word yet with many definitions due to the fact that it may comprise several aspects of human existence. Spirituality is often linked to the human spirit thus it is considered as a superior component for human existence [1]. Furthermore, it is recognized as one of the basic components of health and well-being and as a basic dimension of wellness along with others suc...

Two main arguments are presented in current debates on women and economic empowerment. The right-based argument focuses on increasing women's job opportunities and their freedom to work in security and dignity. The economic argument emphasises women's economic capacities and potential contribution to economic growth. The economic argument draws on the fact that women tend to reinvest their inco...
