The Higher Colleges of Technology was established in 1988 as one of the largest institutions of higher learning in the United Arab Emirates . During the 2012–2013 academic year, there were 11,232 female and 6,855 male students enrolled at 17 campuses throughout the country. More than 55,000 UAE nationals are graduates of the institution.The HCT provides post-secondary education in Business, Education, Engineering Technology, Computer & Information Science, Applied Communications and Health science. English is used as the medium of instruction, with faculty recruited from around the world.The HCT has formal alliances with a number of international tertiary education and training institutions, and corporate partnerships with local and multinational companies. Some programs have international accreditation: for example, the HCT's Bachelor of Education degree was developed with, and is certified by the University of Melbourne.The CERT is the commercial arm of the Higher Colleges of Technology, developing and providing education, training and applied technology for public and private sector clients. The Wharton Center for Family Business and Entrepreneurship Research for the Middle East is based at CERT. The University of Waterloo, Canada, offers dual degrees in collaboration with HCT through CERT.The Chancellor of the HCT is Mohammad Omran Al Shamsi. The Vice Chancellor, appointed in June 2005, is Dr Tayeb A. Kamali.There are 17 campuses throughout the country, with separate colleges for male and female students. The central administration of the HCT is located in Abu Dhabi and includes the Vice Chancellor's Office, Academic Central Services, Institutional Planning and Development, Human Resource division, and Central Finance and IT services.

Resolving disruptions, by dispatching and rescheduling conflicting trains is an NP-complete problem. Earlier literature classify railway operations as: (i) tactical scheduling, (ii) operational scheduling, and (iii) rescheduling. We distinguish the three based on operational criticality. Existing optimisation models do not distinguish precisely between scheduling and rescheduling based on constraints modelling; the only difference is in their objective function. Our model is the first of its kind to incorporate disruptions in an MILP model and to include conflicts-resolving constraints in the model itself. The major advantage of such a formulation is that only those trains which are disrupted are rescheduled and other nonconflicting trains retain their original schedules. Our model reschedules disrupted train movements on both directions of a single track layout with an objective to minimise total delay of all trains at their destinations. Using a small sized data it is proved that all possible conflicts out of a disruption are resolved. Apart from achieving optimal resolutions, we infer through experimental verification that a non-standard dispatch ordering is a requisite for global optimality, as cogitated by other authors. © 2012 Elsevier Ltd.

To date, despite the significant development in the field of structural mechanics, there still remains a paradox in the solutions available for a classical shell buckling problem. The difference in strength between a cylindrical shell under uniform axial compression and that under pure bending is not quite well investigated. This lack of research is reflected in the wide variations in the elastic bending strength and the slenderness limits given in current international design standards. The discrepancies in the available classical solutions and hence the design rules have initiated the current research. The main aim of this paper is to present a closed-form solution for the elastic buckling strength of unstiffened circular cylinders under pure bending using a new simplified energy approach employing the well-known Ritz method. Two types of analyses are presented for cylinders with large (D/t>200) and medium (100 Source

This paper provides strength and durability test results for rubberized concrete that contains silica fume (microsilica) for road side barriers with the intent to reduce injuries and fatalities during crashes. The test program involved the preparation of normal and high strength concretes made out of recycled waste tire rubber. The high strength was obtained by adding silica fume which enhanced the interfacial transition zone bonding. Tire rubber particles composed of a combination of crumb rubber and fine rubber powder were used to replace 10%, 20%, 30%, and 40%, of the total weight of the fine mineral aggregate. The fresh rubberized concrete exhibited lower unit weight and acceptable workability compared to plain concrete. The results of the uniaxial compressive and flexural tests conducted on hardened concrete specimens indicated considerable reductions in axial strength, flexural strength, and tangential modulus of elasticity. Cube Drop tests were performed and showed good resilience of the rubberized concrete. New design guidelines in accordance with the Australian Bridge Design Code AS 5100 for strength and serviceability of rubberized concrete road side barriers were derived based on the test results. New moment-thrust interaction curves and shear strength equations were derived for the rubberized concrete road side barriers. The newly derived design rules showed that shear strength is critical compared to the combined moment and axial thrust and the maximum rubber contents were 17% and 30% for normal and high strength concretes, respectively. © 2014 Elsevier Ltd.

Two case studies of students from California School for the Blind studying artworks in museums and on the Web are discussed. The analysis focuses on the traditional understanding that unreachable artworks in the museum are deciphered by non-intellectual elites primarily from the perspective of visual perception and museums are simple vessels of art, as contended by Ernst Gombrich and Pierre Bourdieu, and that exclusion is either passive or active. It is also argued that there is a bridge between sensing an object and understanding it that is beyond perceptions. The article concludes that the two students featured in the case studies were more likely to be passively rather than actively excluded from unreachable and two-dimensional artworks, and that they could still develop a symbolic intellectual and emotional connection with these artworks and the museum through verbal descriptions and being in their presence. © The Author(s) 2013.

This paper presents experiments and theoretical analysis of 16 steel I-section beams strengthened using externally bonded CFRP under quasi-static large deformation 3-point bending. The main parameters examined in this paper were the section and member slenderness and the location of the CFRP plates. The member slenderness examined in this paper was in the range of L e/r y=40-92. The section slenderness examined in this paper was in the range of b/t f=6.25-16.67. The CFRP plates were added either to the tension flange or both compression and tension flanges or even to the whole section including the web. An expression for the yield and plastic moments of the composite section were obtained by means of an equivalent thickness approach for the web and flange. The newly obtained strength results were compared against the present design rules in steel specifications. The CFRP increased the strength by up to 32% for compression and tension flange strengthening whereas the strength increased only by 15% for tension flange strengthening. The per cent increase in strength for short specimens was mostly affected by the section slenderness where the maximum gain was obtained for the semi-compact section. Plastic mechanism analysis was performed to predict the collapse curves. Good agreement was found between the theoretical and experimental post buckling loaddeflection curves. © 2012 Elsevier Ltd.
