This paper reports the design and scale-up of an active learning exercise centered around color coding of psychrometric charts. The initial version of this exercise was used with small classes of 60 students. When the class size doubled to 120 students, the previously successful exercise failed. The failure was then used as a workshop example for faculty development. Workshop participants successfully identified a number of details of planning and implementation which could be improved, and the revised exercise was once again successful in the classroom. The results are a framework for design of active learning exercises, a number of lessons learned about how to successfully implement active learning in large classes, and a highly polished 2-lecture unit on psychrometric charts, including two animated and worked examples which form part of the paper.

Electromagnetic modeling of split-ring resonators Gurel, Levent; Unal, Alper; Ergül, Özgür Salih (2006-09-15) In this paper, we report our efforts to model split-ring resonators (SRRs) and their large arrays accurately and efficiently in a sophisticated simulation environment based on recent advances in the computational electromagnetics. The resulting linear system obtained from the simultaneous discretization of the geometry and Maxwell's equations is solved iteratively with the multilevel fast multipole algorithm. As an example, we present an array of 125 SRRs showing a negative effective permeability about 92 GHz.
Mobile Robot Heading Adjustment Using Radial Basis Function Neural Networks Controller and Reinforcement Learning BAYAR, GÖKHAN; Konukseven, Erhan İlhan; Koku, Ahmet Buğra (2008-10-28) This paper proposes radial basis function neural networks approach to the Solution of a mobile robot heading adjustment using reinforcement learning. In order to control the heading of the mobile robot, the neural networks control system have been constructed and implemented. Neural controller has been charged to enhance the control system by adding some degrees of strength. It has been achieved that neural networks system can learn the relationship between the desired directional heading and the error posi...
Robust data hidings scheme with turbo codes Ünal, Barış; Ergül, Rüyal; Department of Electrical and Electronics Engineering (2005) This study describes the design and implementation of a robust data hiding algorithm which is provided by turbo codes. As the digital technology grows up, it is getting easy to copy and distribute multimedia products without getting legal permission. This has forced researchers to study in digital watermarking areas. Along with watermarking researches, data hiding studies have gained interest in the last decade. Different watermark and data hiding algorithms have been proposed considering different requirem...
Inverse design of compressor cascades Kaplan, B.; Eyi, Sinan (2001-12-01) In this paper an inverse design method is presented which couples a Navier-Stokes flow solver and a numerical optimization algorithm. The design method generates a compressor cascade, producing a specified surface pressure distribution at a transonic speed. A least-square optimization technique is used to minimize pressure discrepancies between the target and designed cascades. In order to represent the nonlinear, rotational and viscous physics of transonic flows, Navier-Stokes equations are used to predict...
Usability Problem Reports for Comparative Studies: Consistency and Inspectability Vermeeren, Arnold P. O. S.; Attema, Jelle; Akar, Evren; de Ridder, Huib; van Doorn, Andrea J.; Erbuğ, Çiğdem; Berkman, Ali E.; Maguire, Martin C. (2008-01-01) This study explores issues of consistency and inspectability in usability test data analysis processes and reports. Problem reports resulting from usability tests performed by three professional usability labs in three different countries are compared. Each of the labs conducted a usability test on the same product, applying an agreed test protocol that was collaboratively developed by the labs. Each lab first analyzed their own findings as they always do in their regular professional practice. A few weeks ...
