A CRITICAL INTRODUCTION TO DEEP ECOLOGY IN HIGHER EDUCATION: AN APPLICATION OF KOLB’S MODEL OF EXPERIENTIAL LEARNING

The shared understanding that different students in higher education do indeed learn differently - or at least prefer to learn - differently [Diaz and Carrtnal, 1999; Lemire, 1996; Snyder, 2000] makes it necessary for educators to use a variety of methods in their classrooms [Doolan and Honingsfeld, 2000; Ebeling, 2001; Nulty and Barrett, 1996], The fuli involvement of students in the learning process could be achieved through active, rather than passive, learning approaches. Active learning, as opposed to passive learning, directly and actively involves students in the learning process. This means that instead of simply receiving Information verbally and visually, students are receiving and participating and doing[McKeachie, 2001]. Active learning includes everything from listening practices, which help students to absorb what they hear, to complex group exercises in which students apply course materiał to “real life” situations and/or new problems

Automated generation of flat tileable patterns and 3D reduced model simulation

The computational fabrication community is developing an increasing interest in the use of patterned surfaces, which can be designed to show ornamental and unconventional aesthetics or to perform as a proper structural material with a wide range of features. Geometrically designing and controlling the deformation capabilities of these patterns in response to external stimuli is a complex task due to the large number of variables involved. This paper introduces a method for generating sets of tileable and exchangeable flat patterns as well as a model-reduction strategy that enables their mechanical simulation at interactive rates. This method is included in a design pipeline that aims to turn any general flat surface into a pattern tessellation, which is able to deform under a given loading scenario. To validate our approach, we apply it to different contexts, including real-scale 3D printed specimens, for which we compare our results with the ones provided by a ground-truth solver

Prediction of 3D High Frequency Eddy Current Loss in Rotor Magnets of SPM Machines

This paper proposes a computationally efficient method, for accurate prediction of 3-dimensional (3D) high frequency eddy current loss in the rotor magnets of surface mounted permanent magnet machines employing the imaging method. 2D finite element analysis (FEA) is used to generate the information on radial and tangential 2D magnetic field variations (eddy current sources) within the magnet. The diffusion of eddy current sources along the axial plane of the magnet computed analytically is incorporated in the imaging method to establish the 3D eddy current source variations within the magnet. The modified method is validated with results from 3D time-stepped finite element analysis (FEA) for an 8-pole, 18-slot permanent magnet machine, evaluating its magnet loss considering axial and circumferential segmentation

Computationally Efficient 3D Eddy Current Loss Prediction in Magnets of Interior Permanent Magnet Machines

This paper proposes a computationally efficient method based on imaging technique, for accurate prediction of 3- dimensional (3D) eddy current loss in the rotor magnets of interior permanent magnet (IPM) machines. 2D time-stepped finite element analysis is employed to generate the radial and the tangential 2D magnetic field information within the magnet for application of the 3D imaging technique. The method is validated with 3D time-stepped finite element analysis (FEA) for an 8 pole-18 slot IPM machine evaluating its resistance limited magnet loss with increase in axial and tangential segmentation. Magnet loss considering eddy current reaction at high frequencies is evaluated from the proposed method by employing the diffusion of the 2D magnetic field variation along the axial plane. The loss associated with all the frequencies together in the armature currents is evaluated by considering each of the harmonics separately in the proposed method employing the frozen permeability to account for magnetic saturation. The results obtained are verified with 3D FEA evaluating the magnet loss at fundamental, 10 and 20 kHz time harmonics in armature currents

Experimental validation of 3D magnet eddy current loss prediction in Surface Mounted Permanent Magnet Machines

This paper presents the experimental validation of 3D Fourier method employed for predicting magnet eddy current loss in surface mounted permanent magnet (SPM) machines. The magnet loss is measured for a 12-slot,14-pole SPM machine from experimental tests when the machine is operated with inverter under locked rotor conditions by repeating tests with two rotors, one with magnets and one without. The eddy current loss associated with each significant harmonic in the captured armature currents is predicted separately employing the developed method and the total magnet loss is evaluated by applying the principle of superposition. The magnet loss at real operating conditions of the machine is predicted from the method using the phase current captured when the SPM is operating at its maximum speed conditions. The result is used as example to devise an effective means of further reduction in the total magnet loss

Information Privacy and Emerging Technologies in the U.A.E. Current State and Research Directions

The rapid developments in the front of emerging technologies, such as Big Data, Cloud Computing, and Internet of Things, pose certain challenges for societies that are trying to keep up with the changes these technologies introduce. As a consequence, significant concerns are being raised in relation to such developments. One of the most widely debated and discussed issue in relation to the latter, has to do with the potential threats to personal information privacy. This paper briefly introduces some of the related emerging technologies and explores some of the expressed concerns on information privacy and disclosure in the U.A.E. in this context. In addition, related research themes that could be interesting to explore in the future are being identified, with a focus on the local socioeconomic environment

Peptic Ulcer Perforation as the First Manifestation of Previously Unknown Primary Hyperparathyroidism

A patient admitted for acute abdomen was incidentally found with elevated serum calcium level. In surgery, under conservative treatment of the hypercalcemia, a perforated duodenal ulcer was found and simple closure was performed. Postoperatively, calcium level continued to rise, parathyroid hormone was elevated and ultrasonographic examination showed a lesion in the right anterior neck, while serum gastrin level was normal, thus documenting the diagnosis of primary hyperparathyroidism. Conservative treatment had no effect on calcium level and the patient was subjected to emergency neck exploration, where a large parathyroid adenoma was removed. After surgery, calcium and PTH levels were normalized and the patient was discharged on the 5th postoperative day. Peptic ulcer and its complications are usual manifestations of primary hyperparathyroidism, with or without increased gastrin level. On the other hand, cases of a perforation of peptic ulcer as the first clinical manifestation of primary hyperparathyroidism are extremely rare
