The Power of Creative Space in Engineering Education
In order to graduate globally capable engineers who are not only technically savvy, but socially competent and business smart, Sheridan’s School of Engineering has found both a process and a ‘place’ to meet these goals and align with their vision to create curricula that inspire innovation and creativity. The process: the CDIO methodology that helps graduate “ready to work” engineers. The place: Sheridan’s Centre for Advanced Manufacturing and Design Technologies (CAMDT).
In the fall of 2013 Sheridan unveiled its new visual identity with a tag line that challenges people to get creative. It\u27s a bold and courageous statement that reflects Sheridan\u27s belief that creativity is, among other things, an essential life skill. Our focus on creativity, which can best be described as \u27creativity with purpose\u27 or \u27practical creativity,\u27 extends across all programs. It\u27s about challenging students to re-imagine ideas, experiment, collaborate, take risks and build a resourceful, resilient and flexible mind. How realistic and authentic is this Creative Campus philosophy at Sheridan? How did this notion of creativity make its way into our mission, values and strategic goals?
For the CDIO methodology to translate into outcomes, students need the creative space to get the real world practice that makes CDIO such a powerful learning strategy. Operating like a research and development arm for small and medium sized enterprises, CAMDT unites engineering students, faculty and community partners to solve real world challenges and produce solutions that benefit the local economy. At Sheridan, CAMDT is not just a physical space, it’s a creative space where the collaboration between engineering students, educators, industry and community partners not only benefits enterprise partners, but helps Sheridan shape engineering education.
In travelling down the road to university recognition, Sheridan has engaged its academic community to describe the characteristics that best represent the Sheridan University of the future. It is through this process that the plan for the Creative Campus emerged. The paper reviews Sheridan’s Creative Campus Strategy and draws parallels to the four high-level expectations in the CDIO syllabus
About Local Optimum of the Weber Problem on Line with Forbidden Gaps
Abstract. The location problem of interconnected facilities on the line with forbidden gaps is considered. The located facilities are connected among themselves and with gaps. Location in forbidden gaps is not allowed. It is need to minimize the total cost of connections between facilities and between facilities and gaps. It is known that the initial continuous problem is reduced to series discrete subproblems of smaller dimension. In this paper the definition of the local optimum of the problem is introduced. In order that to obtain the local optimum it is necessary to solve some subproblems. The variants of lower bounds of the goal function of the subproblems are proposed. The bounds can be used in the branch and bounds algorithm for solving the subproblems
Measuring system for testing electrical parameters of EMCCDs of various formats
This article describes the developed equipment that allows measuring the photoelectrical parameters of multielement photodetectors, specifically various formats of EMCCD (electron multiplying charge-coupled device) chips. The authors present the measuring techniques and test results on dark currents, output amplifier sensitivity, charge transfer efficiency, charge capacity and other parameters. The studies were conducted, both on the wafer and in the body, on samples of the following formats: 576×288, 640×512, 768×576, 1024×1024, and 1280×1024.В данной статье описывается разработанное оборудование, позволяющее измерять фотоэлектрические параметры многоэлементных фотоприемников, в частности, различных форматов микросхем ПЗСЭУ (приборы с зарядовой связью и электронным умножением).

Gamma radiation exposure of MCT diode arrays
Investigations of electrical properties of long-wavelength infrared (LWIR)
mercury cadmium telluride (MCT) arrays exposed to gamma-radiation have been
performed. Resistance-area product characteristics of LWIR n{+}-p photodiodes
have been investigated using microprobe technique at T=78 K before and after an
exposure to various doses of gamma-radiation. The current transport mechanisms
for those structures are described within the framework of the balance equation
model taking into account the occupation of the trap states in the band gap.Comment: 11 pages, 4 figures, submitted to Semiconductor Science and

Zero bias terahertz and subterahertz detector operating at room temperature
In this paper, the experimental study of the terahertz and subterahertz hot
electron bolometer based on narrow-gap semiconductor compound Hg₁₋xCdxTe is
presented. The measurements were performed in the temperature range from 77 to
300 K at various operating mode and frequency. The estimated value of the noise
equivalent power at room temperature for detector proposed was 1.3·10⁻⁸ W/Hz¹/² and
5.4·10⁻⁹ W/Hz¹/² at bias current I = 1 mA and I = 0, respectively
Detection of IR and sub/THz radiation using MCT thin layer structures: design of the chip, optical elements and antenna pattern
Two-color un-cooled narrow-gap MCT (mercury-cadmium-telluride) semiconductor thin layers, grown by liquid phase epitaxy or molecular beam epitaxy methods on high resistivity CdZnTe or GaAs substrates, with bow-type antennas were considered both as sub-terahertz direct detection bolometers and 3...10-micrometer infrared photoconductors. Optical system with aspheric THz lenses were designed and manufactured. An antenna pattern of structures on the thick substrate was discussed, and sensitivity of detector in both IR and sub-THz regions was measured
