TEACHING INTERFACING FOR REAL-TIME SYSTEMS: NOW AND TOMORROW
Authors: Kinser Witold , Schor Dario , Beigun Ken 
Published: April 2017

Teaching undergraduate students about interfacing of microprocessors and microcontrollers in real-time systems is challenging because the circuits have moved from medium to increasingly higher frequencies (multimega- and giga hertz), while wired interfacing has been augmented with wireless interfacing. This paper describes an attempt to accommodate the changes in an undergraduate course called Microprocessor Interfacing (µI) that has been offered at the University of Manitoba for many years now [1-4].The course presents real-time wired and wireless interfacing of microcontrollers, microprocessors, and microcomputers to the external world, including interfacing of input/output (I/O) devices with minimum hardware and software, as well as data acquisition with and without microprocessors, data communications, transmission and logging with embedded computers. The following topics are covered: (i) introduction on computing, architectures, processors, and technologies, (ii) architecture and organization of small computer buses, and synchronization of data transfers on local buses (iii) digital input and output (I/O), (iv) digital-to-analog (D/A) and analog-to-digital (A/D) signal conversions and converters, (v) and interfacing aspects in data communications, including encoding, modulation, error detection and forward error protection. The course also includes (a) demonstrations of bus architectures, modules, systems, and new devices, as well as (b) updates on new concepts, technologies, protocols, and software. The laboratories are innovative in terms of three levels of complexity: the Tier1 level includes five 3-hour standard labs designed for all students, the Tier2 is designed for more experienced students, and the Tier3 level lab is designed as a project for groups of students with demonstrated prior design and implementation experience [3].Tomorrow’s teaching will require a deeper exposure to high-speed circuits, as the impact of the distributed nature of signals in circuits increases due to the circuit interconnections acting as transmission lines. This requires software-based simulation and emulation of designs. Embedded systems on a chip may mitigate the problem to a degree. Course laboratories may also change because of the inexpensive equipment such as logic analyzers, protocol analyzers [5], and computer-based digital oscilloscopes. Since the test cost of such equipment is within a range of a student, laboratories-athome may also become a reality.The paper provides a description of a class structure of an interfacing course today, and identifies changes required by future material in such as course. An example of an implementation of a change is also provided.
TRANSLATING A CORPORATE LEADERSHIP PHILOSOPHY AND PRACTICE TO THE ENGINEERING CLASSROOM
Authors: Colcleugh David , Reeve Doug 
Published: April 2017

A multi-billion dollar chemical company (DupontCanada) developed, over twenty years, a unique leadership philosophy and practice that was instrumental in the company’s remarkable improvement and great financial and societal success. The beliefs that are fundamental to this Developmental Leadership model are: values are the foundation of leadership; everyone can learn to lead; leaders develop role model leading competence through learning certain skills, character attributes and purposeful behaviours; the work of leaders in organizations is developing high performance work systems dedicated to achieving sustainable growth; and learning to be a better leader is a life-long endeavor. A leadership course for engineering students based on this was developed by the former CEO and Chairman of the company (first author David Colcleugh), an engineer by training, and has been offered to undergraduate and post-graduate engineering students at the University of Toronto since 2007. At first the course was offered as a combined undergraduate-graduate course. In 2011 it was decided to offer separate coursesfor graduate students and undergraduate students. Atextbook, Everyone a Leader, was prepared (byColceugh) and beginning in 2012 was used, in manuscript form, in both courses. The textbook provided the curriculum and instructional framework that permitted a second instructor to lead the course –(second author Doug Reeve). The Developmental Leadership Model serves as a framework for instruction so long as the instructor’s own leadership experience is well integrated into course discussions. The course hasnow been offered eight times.The motivation for the course arises from the belief that engineering students should, in addition to having strong scientific and technical capabilities and being self-motivated to contribute, should be well prepared emotionally, socially, and ethically to accept challenges and should be to committed to develop non-technical as well as technical competencies.
TEACHING FEEDBACK CONTROL THEORY USING AN INTEGRATING DESIGN PROJECT
Authors: Couturier Michel F. 
Published: April 2017

Teaching feedback control theory is challenging because it is important to cover theoretical material intended for fundamental understanding as well as material directly related to industrial practice. One approach to reach this dual objective and prevent control theory from becoming abstract to students is to assign a design project that requires integration of all main concepts taught in class. This approach has been successfully used in eight offerings of the course ChE 3601 Process Dynamics and Control in the Chemical Engineering program at the University of New Brunswick. The one-semester course is an introduction to the dynamic behavior of chemical processes and feedback control loops. The project is assigned at the beginning of the course and involves the design of a feedback control system for a realistic chemical process. The design project is divided into five milestones with deliverables due every two weeks. The final report due at the end of the course must include a description of the proposed system using a P&I diagram, specifications for all control equipment, a dynamic model for all components of the feedback loop, settings for the tuning parameters of the PID controller, and dynamic simulations using Polymath to validate the proposed solution. The course is organized around the project in a manner similar to that used in problem-based learning. The active learning approach used in ChE 3601 provides a deeper understanding of control theory and its application.
Design of a teachers’ training workshop for improving technology integration skills
Authors: Mavinkurve Madhuri , Patil Mahesh 
Published: April 2017

Educationists and researchers recommend integration of simulations in classrooms to promote student-centric constructivist learning. The simulations need to be carefully designed toward improvement ofconceptual understanding of students. In this paper, we report on a training workshop for teachers with the specific goal of imparting simulation integration skills for classroom teaching. In the workshop, we used SEQUEL, a freely downloadable circuit simulator, and focused on electronic circuits taught typically at the second-year undergraduate level. We applied education technology principles as well as constructivist alignment methods to design the workshop. In particular, collaborative learning strategies such as think-pair-share and peer instruction were covered specifically for the intended simulation integration. Furthermore, application of the flippedclassroom model in the context of circuit simulation was explained to the participants. We report on the workshop design in detail and report the impact of the training workshop on integration skills of the teachers. We found that teachers (N=15) perceived the workshop to be usefulin designing their aligned lesson plans. Teachers also reported their field study in which they found improved motivation of students to solve electronics circuit problems.
TEACHING AND ASSESSING “LIFELONG LEARNING” IN ENGINEERING COMMUNICATION COURSES
Authors: Patterson Laura , Labun Carolyn , Eikenaar Jannik 
Published: April 2017

Recent changes to CEAB’s accreditation process have resulted in the need for engineering programs in Canada to find ways to assess critical graduate attributes. While many of the attributes can be measured through traditional methods, others are more subtle and challenging to assess. One that can be particularly challenging both to teach and assess is lifelong learning. As its name suggests, lifelong learning is a process that begins before and continues after a person’s formal education; it is a learner-initiated activity or habit of mind. As such, educators must develop ways to ensure that students understand the importance of learning itself, both during and after their formal engineering studies.Technical Communication courses are excellent vehicles for delivering and reinforcing the skills and competencies associated with lifelong learning. This paper will explore how “Lifelong Learning” as a CEAB graduate attribute can be taught and assessed in communication courses (APSC 176 and APSC 201) housed in an engineering program at UBC’s School of Engineering. This paper will also explore the next steps in developing appropriate metrics for determining the success of these courses in meeting this element of accreditation.

Published: April 2017

Four Canadian Engineering Education students from the Universities of Manitoba, Saskatchewan, Toronto and Calgary have conceptualized conducting a national study to characterize the identities of graduate students studying Engineering Education in Canada. We developed the Canadian Engineering Education Student Identity Study (CEESIS). This is a mixed methods cross-case comparison research study designed to explore how Canadian Engineering Education graduate students’ identities are formed through the intersection of our intellectual, institutional and networking academic experiences nested within our personal lives.In this paper, we detail the realization, purpose, benefits, theoretical design and methodology of this study. The development of our theoretical framework and survey through the use of McAlpine’s identity-trajectory construct is discussed. We conclude with individual personal reflections on how this research process has shaped our own growth as Engineering Education graduate students and how participation in this research group has influenced our understanding and identity of being Engineering Education graduate students and emerging Engineering Education researchers in Canada

Published: April 2017

Background Head and neck ossifying fibroma (OF) is a rare, benign, locally aggressive, fibro-osseous tumor. The mandible is the most common site of involvement, followed by the maxilla, and, less frequently, the sinonasal cavities, orbit, skull base, and calvarium. In this study, we aimed to expand our understanding of this entity by presenting a case series of OF that involved the maxilla and sinonasal tract. Methods A multicenter retrospective review was performed on all the patients with a diagnosis of OF from 2004 to 2013. Data were collected with respect to age, sex, clinical presentation, treatment, and outcome. Results A total of 13 patients were identified. The mean age was 37 years, with a female predominance (69%). The maxillary sinus was most frequently involved site (46%). Eighty-five percent underwent open surgical resection. After a mean follow-up time of 47.3 months, three patients (23%) developed recurrent disease; all of whom were treated with an open approach. Conclusion OF of the maxilla and sinonasal tract is an uncommon clinicopathologic entity. Although a timely diagnosis may obviate the need for external approaches, open surgical resection is often still necessary for management of extensive lesions. Close follow-up and additional surgery may also be required to treat recurrent disease.

Published: April 2017

Background There is preliminary evidence that patients with chronic rhinosinusitis (CRS) and comorbid obstructive sleep apnea (OSA) have reduced quality-of-life (QOL) improvements after functional endoscopic sinus surgery (FESS) compared with patients without OSA. The effect of OSA severity on QOL improvement after FESS is unknown. Objectives To better characterize the QOL improvement after FESS for patients with comorbid OSA and to assess whether QOL improvement is dependent on OSA severity. Methods This multi-institution, retrospective cohort study evaluated adult patients with CRS who underwent FESS between 2007 and 2015. Preoperative, 1-month, 3-month, 6-month, and 1-year postoperative 22-Item Sino-Nasal Outcome Test scores were used to evaluate QOL. We compared patients without OSA with patients with stratified OSA based on the preoperative apnea-hypopnea index. A multilevel, mixed-effects linear regression model was used for the analysis. Results Of 480 participants, 83 (17%) had OSA, and 47 of these patients had polysomnography results available for review. Both patients with OSA and patients without OSA reported significant QOL improvement after surgery (p < 0.0001) relative to baseline. In the unadjusted model, the subjects with OSA demonstrated a statistically worse outcome in 22-Item Sino-Nasal Outcome Test scores at each time point (2.4 points higher per time point, p = 0.006). When controlling for covariates, the adjusted model showed no difference in QOL outcome based on OSA status (p = 0.114). When stratified by OSA disease severity, the adjusted model showed no difference in the QOL outcome. Conclusions Patients with CRS and comorbid OSA had worse QOL outcomes after FESS; however, when controlling for patient factors, there was no difference in QOL outcome. OSA disease severity did not seem to predict QOL improvement after FESS.

Published: April 2017

Background: Migraine causes difficulties in daily life. Objective: The purpose of this present study was to assess the severity of migraine associated with comorbidities.Methodology: This cross sectional study was carried out in Headache Clinic and Neurology outdoor in the Department of Neurology at Dhaka Medical College and Hospital (DMCH), Dhaka during the period of July 2010 to June 2011 for a period of one (01) year. All the patients presented with migraine were included as study population who were divided into two groups. Migraine patients without comorbidities were designated as group I and with comorbidities were in group II. The comorbidities were assessed which were both physical as well as psychiatric. The severity of migraine was assessed on the basis of four principal components like pain intensity, nausea, disability and tolerability.Result: A total of 70 patients with migraine were recruited of which 37 patients were in group I and 33 patients were in group II. In group II major depressive disorder was in 8(24.3%) cases, generalized anxiety disorder was in 6(18.1%) cases and hypertensive was in 7(21.2%) cases. Among 8 major depressive disorder patients, mild, moderate and severe migraines were found in 1(3.03%) cases, 2(6.06%) cases and 5(15.15%) cases respectively. Out of 6 GAD patients, mild, moderate and severe migraine were found in 1(3.03%) case, 1(3.03%) case and 4(12.12%) cases. Seven patients were hypertensive of which 1(3.03) patient had mild, 2(6.06%) had moderate and 4(12.12%) had severe migraine. Mild migraine was found in 18(48.6%) patients in group I and 6(18.2%) patients in group II. Moderate migraine was found in 12(32.5%) patients and 8(24.2%) in group I and group II respectively. Severe migraine was found in 7(18.9%) patients in group I and 19(57.6%) patients in group II.Conclusion: Severity of migraine is associated with different physical and psychiatric comorbidities.

Authors: Hossain Md Shahadat , Begum Hasina , Haider Ismat Ara , Sarker Md. Selim 
Published: April 2017

Background: Tracheal intubation in oro-maxillofacial surgery is an important issue during operation. Objective: The purpose of the present study was to demonstrate the feasibility and the reliability of submandibular tracheal intubation as an alternative method for airway management in oro-maxillofacial surgery. Methodology: This clinical trial was conducted in the Department of oromaxillofacial Surgery at Dhaka Dental College and Hospital, Dhaka from January 2010 to June 2011 for a period of one and half year. Patients suffering from painful fractures associated with displaced nasal fracture were selected as study population. Results: A total number of 9 patients were recruited for this study of which 1 was female and 8 were males and the age range was between 16 to 51 years. The technique was found easy and offers a secure airway to the anaesthetist, an optimal operating field and an opportunity to check the dental occlusion with limited morbidity for the patient. In all patients the submandibular tracheal tube was extubated after the operation without complications or difficulties. Accidental dislodgement of the tube to the right main bronchus occurred in one patient while carrying out the procedure. It was rapidly detectedand corrected. No other complications were encountered. Conclusion: Submandibular tracheal intubation is a safe, simple and effective technique for upper airway management when both oral and nasal tracheal intubations are not convenient in some oromaxillofacial surgery.

Scottish Rolls of Honour and Rolls of Service: A Neglected Source
Authors: Riddell Linda 
Published: April 2017

Although built memorials of the Great War have been the subject of academic research, rolls of honour and service have been accorded much less attention; nevertheless they are potentially of great interest and value for historians. This article examines rolls covering geographical areas of Scotland, showing that they often contain much more than lists of those who fought and those who died. As written documents, they are not so dependent as monuments are on symbolism to convey meaning and their overt language is more susceptible to analysis. Besides their obvious value for the study of family history and the history of particular localities in the war and soon after, they can be scrutinised as an example of how local history can add nuanced understanding of an international event and challenge generalisations based on limited evidence mainly from large urban areas. They are also illustrative of the thoughts and aspirations of the compilers, providing insights about perceptions not only of the Great War and perhaps war in general, but also of class, gender roles, religion, children and education. The rolls can contribute to debates about continuity and change, about modernism and tradition, as well as the interplay between local and national identities.
Phase transformations in liquids and the liquid–gas transition in fluids at supercritical pressures
Authors: Brazhkin V V 
Published: April 2017

Abstract
It is an experimental fact that in the neighborhood of melting curves, including those measured at above-critical pressures and temperatures, all fluids have some short- and intermediate-range order and their excitation spectra contain high-frequency transverse waves. At high pressure, both smooth and sharp first-order phase transitions involving changes in the liquid structure and properties can occur between various liquid states. However, at sufficiently high temperatures, any liquid loses its identity and turns into an unstructured dense gas in which only longitudinal waves can propagate. We discuss theoretical and experimental evidence for the existence of a boundary between a ‘solid-like’ melt and a dense gas at supercritical pressures.
Aux filles et aux fils des dieux du carnage. Filiations religieuses dans la psychanalyse
Authors: Tort Michel 
Published: April 2017

Le rapport que la psychanalyse entretient aux normes et au genre est profondément lié à la religion et aux religions. L’enjeu est de poursuivre l’entreprise de L’avenir d’une illusion en repérant ses butées. On reconstitue d’abord comment les positions religieuses notamment chrétiennes sont l’horizon des débats passionnés sur le genre et les sexualités depuis les années 1970, après les mouvements de 1968. Certains psychanalystes ont tendance depuis à faire dériver leurs discours et leurs pratiques de ces positions religieuses traditionnelles. Des notions psychanalytiques données pour fondamentales, comme la « fonction paternelle », sont solidaires de cette dérive et traduisent l’intrusion dans la psychanalyse du patriarcat religieux. On montre les difficultés des psychanalystes à sortir de leurs histoires avec leurs religions. On examine enfin la consistance du modèle freudien de la maladie religieuse issu de L’avenir d’une illusion en l’appliquant à la « maladie chrétienne » dont on fait ressortir les ravages historiques redoutables, à un moment où d’autres religions lui font concurrence.
Le pouvoir de l’autonomination. Sur la loi argentine d’identité de genre
Authors: Rosenberg Martha I 
Published: April 2017

L’assignation de sexe initiale et la réassignation de genre autoperçu sont-elles tributaires d’une conception essentialiste de la sexuation ? Ont-elles en partage l’idée qu’à une position sexuée au sein du binarisme conventionnel correspond une morphologie anatomique déterminée ? Procèdent-elles à un diagnostic de normalité ou de pathologie en lisant l’apparence des organes génitaux externes à partir d’un appareil idéologique de réduction de la sexualité à une finalité reproductive ? Le traitement d’adéquation de l’image au vécu n’indique-t-il pas que la correspondance entre ces deux instances « normalise » et confère ainsi une intelligibilité aux corps humains qui ne correspondent pas aux modèles ?
La représentation qui rend fou… Psychopathologie du processus représentatif dans les états psychotiques
Authors: Di Rocco Vincent 
Published: April 2017

Cet article s’appuie sur l’hypothèse qu’une représentation peut paradoxalement confronter l’appareil psychique à l’irreprésentable, l’irreprésentable n’étant pas lié directement à la nature du vécu à représenter, mais à ce qui apparaît comme un échec du travail de transformation des processus psychiques. Cette confrontation à l’irreprésentable mobilise la psyché selon deux registres : d’une part, les différents registres de l’expression symptomatique peuvent être compris comme une tentative de représenter le vécu qui reste insaisissable, et d’autre part, dans le cadre psychothérapique, les modalités d’expression du sujet représentent une tentative de figurer le processus psychique en échec. Deux exemples cliniques illustrent ces logiques.
