Dubai, United Arab Emirates

Rochester Institute of Technology - Dubai is a satellite campus of Rochester Institute of Technology, New York, USA in Dubai, United Arab Emirates. The college, is located in the Dubai Silicon Oasis and started offering part-time graduate courses in Fall 2008. In 2009, the university began its full-time graduate program. RIT Dubai's first graduating class was in 2010, with the graduation ceremony taking place in Rochester, NY. In 2010, a full-time undergraduate program was started as part of the university's planned expansion. In the fall of 2011, RIT Dubai moved its campus to a new premises to accommodate the growing student body. By 2019, RIT plans to expand the campus to 1,000,000 square feet to provide facilities for 4,000 students.The RIT Dubai campus is the Rochester Institute of Technology's third international campus. The university's other satellite campuses are American College of Management and Technology located in Croatia and American University in Kosovo. Wikipedia.

The current worldwide effort to integrate sustainability components within University curricula is generating increasing demand for coursework directed at green and sustainable building design. The overarching outcomes of these courses include understanding the building energy balance, and the application of appropriate strategies to reduce instantaneous and yearly energy consumption. The respective course syllabi often focus on examples applicable within the range of the regional or national climatic conditions; for example, in the UAE little time is typically spent on discussing heating equipment; the focus is on air conditioning and reduction of solar gains. In addition to climatic considerations, building energy-efficiency related coursework requires developing an understanding of what the consumption is when instantaneous energy use is integrated over the hours of the day and over the course of a year. This step is not intuitive, as, while the theoretical background is primarily developed in steady state (such as heat transmission through walls and windows, infiltration, solar gains, heating and air conditioning loads, etc.), the effectiveness of the measures is typically assessed by the change in the building's annual consumption (and thus includes daily and seasonal cycles). The combination of both factors, the need to investigate energetic strategies in widely varying climatic environments, and the difficulty in developing engineering intuition of the long-term effect of efficiency measures, make energy simulations an attractive tool for an experiential learning approach. Especially locations with a strong international exposure, such as RIT Dubai, which hosts of a variety of nationalities from the Gulf region as well as students from the US main campus (thus at home in very different climatic regions), require a global approach for the teaching of sustainable buildings, and can thus benefit most from using energy simulations in their sustainable building courses. The experiential learning component utilized here follows the recommendations of the well established methodology by Kolb [6] and was integrated into a graduate course in Sustainable Energy Management in the Built Environment in the form of a series of simulation-based exercises and projects. The simulation assignment sequence is matched with the course lecture content, the experiential learning sequence, and the learning curve of the simulation software, starting with the analysis of a given building under given circumstances, followed by the critical observation of the results, and the subsequent formation of abstract formulations to be tested in the form of new, increasingly open-ended design projects. A key point is the requirement to carry out these design simulations in different climates (including both cooling and heating environments), and for the two principal energetic building classifications - internal load dominated and envelope dominated. The work presented here discusses the motivation for and effectiveness of simulation-based experiential learning in the sustainable buildings context, presents the approach taken at RIT's Dubai campus, and discusses lessons learned and outcomes. After two course iterations, and subsequent formative and summative assessment of this experiential component in particular, results show high levels of student support, and significant enhancement of perceived learning.

In interference-limited OFDMA systems, fractional frequency reuse (FFR) algorithms can be used to combine the superior performance offerings of a universal reuse plan near cell center and a higher reuse plan near cell edge. A proper configuration of FFR requires knowledge of throughput statistics at all locations in the cell coverage area. This paper introduces an analytical optimization technique to configure a FFR solution for the downlink of LTE cellular system based on a throughput model developed herein. The optimal configuration is based on maximizing the average sector throughput subject to a minimum cell-edge performance and other performance constraints related to the standard reuse plans. © 2012 IEEE.

An assessment of the structural integrity of members containing irregularly-shaped cutouts necessitates knowing the associated stresses. Stress analysis of such structures can be challenging as theoretical solutions are seldom available for finite geometries having non-simple shaped discontinuities and, like numerical methods, they require accurate knowledge of external loads. The latter are often unavailable in practice. This paper describes the ability to process load induced temperature information with an Airy stress function in real polar coordinates to determine the stresses in an isotropic linear elastic finite tensile plate containing an irregularly-shaped hole. Using polar coordinates is significant in that while a relatively simple general solution to the governing biharmonic equation is available in polar coordinates, this is seemingly not so with orthogonal curvilinear coordinates. Compared with displacement-based experimental or finite element techniques, important advantages of the present technique include not having to differentiate recorded data, or know constitutive properties or external loads. © 2013 Society for Experimental Mechanics.

My ab initio electronic structure calculations in RSn2n-1Te2n, n=16, R = a vacancy, Cd, and In show that when Sn atom is substituted by R, the Density of State (DOS) of the valence and conduction bands get strongly perturbed. There are significant changes near the band gap region. Sn vacancy causes very little change near the bottom of the conduction band DOS whereas there is an increase in the DOS near the top of the valence band. Results for In impurity shows that, unlike PbTe, the deep defect states in SnTe are resonant states near the top of the valence band. In PbTe these deep defect states lie in the band-gap region (act as n-type). This fundamental difference in the position of the deep defect states in SnTe and PbTe explains the experimental anomalies seen in the case of In impurities (act as n-type in PbTe and p-type in SnTe). © (2013) Trans Tech Publications, Switzerland.

In this work, we describe a security solution that can be used to securely establish mobile payment transactions over the Near-Field Communication (NFC) radio interface. The proposed solution is very lightweight one; it uses symmetric cryptographic primitives on devices having memory and CPU resources limitations. We show that our approach maintains the security of NFC communications and we further demonstrate that our solution is simple, scalable, cost-effective, and incurs minimal computational processing overheads. © 2016 Published by Elsevier B.V.
