geometric and material nonlinear behavior of slender webs in i-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. in addition, the effects of flange and web slenderness rati...

This paper is based on the adage that 'good privacy is good business'. Personal information holds significant value and web based businesses often seek to monetize that value. Unlocking personal information value in web based businesses, like social networks, can lead to disclosure of private and sensitive information, and subsequent harm. Personal information management business practices are ...

In this paper, Web 2.0 open content mashups or combinations are explored. Two case studies of recent initial teacher training programmes are reviewed where blogs and wikis were blended to create new virtual learning spaces. In two separate studies, students offer their views about using these tools, and reflect on the strengths and weaknesses of this approach. There is also discussion about agg...

The tension–tension fatigue behavior was investigated for a hybrid composite rod comprised of a unidirectional carbon fiber core and a glass fiber shell. Fatigue tests were performed at three R-ratios and four maximum applied stress levels (MAS) while recording the secant modulus at each cycle, and acoustic emission (AE) sensors were employed to monitor the activation of fatigue mechanisms. Fat...

.ABSTRACT: This paper discusses the material characterization of wide flange pultruded structural shapes (E-glass, Vinylester). The material was subjected to three loading conditions: tension, shear, and bending. Coupon samples were obtained from web and flanges of the I-section for tension and shear tests. Tensile properties were obtained from rectangular coupons with end tabs loaded in tensio...

search pointers organize the main part of the application on the internet. however, because of information management hardware, high volume of data and word similarities in different fields the most answers to the user s’ questions aren`t correct. so the web graph clustering and cluster placement in corresponding answers helps user to achieve his or her intended results. community (web communit...

In web transport systems, the main concern is to control independently speed and tension in spite of perturbations such as radius variations and changes of set point. In this paper we present multivariable H2 controllers, with and without integrator, applied to winding systems. Different controller structures are considered: a centralized and a semidecentralized controller with or without overl...

The aim of the study was to evaluate an innovative learning project in which middle school students and teachers completed chosen, group inquiries through virtual collaboration in a web-based learning environment. The students' task was to accomplish a cross disciplinary inquiry into cultural phenomena. Students worked mainly at home during the project and took much responsibility for their own...

In cable production, it is imperative to control speed and tension. This paper proposes a web tensile force regulation between input output pulling caterpillar devices. The controlled indirectly using PI controller based on feedback information about observer. also deals with the of input-pulling device torque (current) effect line temperature change at extruder zones. output-pulling devices ar...
