Experimental investigation on shear strength of elastic end-web panels strengthened with CFRP strips
S. S. Safar and Mohamed N. Abou-Zeid
An experimental program was conducted to investigate the shear strength of elastic end-web panels of steel plate girders strengthened with intermediate-modulus carbon fiber-reinforced polymers, CFRP, strips. Test parameters included; number of strips, aspect ratio of end-web panel and width-to-thickness ratio of web plate. Twelve plate girder specimens composed of mild-steel were loaded in a four-point bending test till failure. The girders were proportioned so that the load capacity was governed by elastic web buckling. Four specimens were not strengthened to serve as reference girders whereas the remaining specimens were strengthened by applying CFRP strips in the diagonal tension direction on one or both sides of the web. Test results indicated that the buckling strength of strengthened specimens was not improved, however, the ultimate shear strength increased by 6% to up to 120% due to significant increase in post-buckling strength. The increment in post-buckling strength due to pasting CFRP strips on web plate was several multiples of that of reference girders and was reduced when slender web plates or long end-web panels were utilized. In addition to higher ultimate shear capacity, it was observed that vertical deflections, out-of-plane displacements of the web and bending curvature of transverse stiffeners of strengthened girders were reduced at ultimate load. It was concluded that the ultimate shear strength of elastic end-web panels was successfully improved using intermediate-modulus CFRP strips. On the other hand, current design rules adopted by current AISC specifications need to be revised to account for post-buckling strength of elastic end-web panels.

Normatizing State Power: Uncritical Ethical Praxis and Zionism
Steven Salaita
I do not believe that the production of research should be democratic, but its dissemination should not be so patently undemocratic. We need to think more about how the work we do as scholars coheres with the struggles of projustice advocates in all social and economic strata. I don’t have all the answers to these propositions, but I do know that on the cusp of promotion to associate professor, I’ve learned a few things about scholarship: if it claims to be objective, then it’s lying to you. And if it’s not political, then it doesn’t exist.

Hierarchical prior zero-forcing for cognitive relaying
Feeby Salib and Karim G. Seddik
In this paper, cognitive radio relaying in the physical layer is investigated where the cognitive base station (CBS) relays the PU's signal while transmitting its own signals to its secondary users (SUs). A new and simple linear method for beamforming, based on zero-forcing beamforming, adapted for the different levels of priority that users may possess in a cognitive radio network, is proposed and the special case of two SUs is analytically studied. © 2014 IEEE.

On the stability of random multiple access with feedback exploitation and queue priority
Karim G. Seddik
In this paper, we study the stability of two interacting queues under random multiple access in which the queues leverage the feedback information. We derive the stability region under random multiple access where one of the two queues exploits the feedback information and backs off under negative acknowledgement (NACK) and the other, higher priority, queue will access the channel with probability one. We characterize the stability region of this feedback-based random access protocol and prove that this derived stability region encloses the stability region of the conventional random access (RA) scheme that does not exploit the feedback information. © 2014 IEEE.

Network fabric fault-tolerance for Ethernet-based Networked Control Systems
Christine H. Alfi, Yara K. Hilal, Gina H. Aziz, Hassan H. Halawa, and Ramez M. Daoud
Networked Control Systems (NCS) are widely used in industrial applications. Ethernet has recently been used as the communication protocol in NCS. Since overcoming faults is crucial in control systems, fault-tolerance in NCS is being extensively investigated. This paper focuses on the fault-tolerance aspect of Ethernet-based NCS at the network fabric level. It proposes a novel architecture that achieves successful recovery from any single link or switch failure. The model was also tested and proved to be fault-tolerant for some multiple failures. © 2013 IEEE.
