The trend towards smaller and less expensive spacecraft continues. The University of Manitoba has participated in the design and implementation of a triple-pico-satellite (code TSat) since 2010, with over 100 undergraduate and graduate students from five faculties and 16 departments, as well as 50 advisors from academia, aerospace industries, business, military, and government. Such small satellites are used for atmospheric study and testing of new research concepts such as new forms of data communications, and constellations of space robots. A graduate course on small spacecraft engineering has recently been developed to address the needs of many students in this area. The course provides foundations for the design, implementation and testing of nano-, pico- and femto-satellites. The topics cover the anatomy of a small spacecraft, its design process with the specific design of its mission and payload, orbital mechanics, spacecraft subsystems, and mission operations handling. The specific subsystems include (i) attitude determination and control (ADC), (ii) telemetry, tracking, and command (TTC), (iii) command and data handling (CDH), (iii) power (PWR), (iv) thermal (TRM), (v) structures (STR), and (vi) guidance and navigation (GAV) [1-3]. Emphasis is given to the algorithms and computing tools for such small satellites. The basis for modeling and simulation is the Systems Tool Kit (STK) from Analytical Graphics Incorporated (AGI). The course is supported by our experience in developing the TSat1 nano-satellite. This paper describes the structure of the course, the methodology used, the set of topics covered, the set of course projects, and the lessons learned from the delivery of this unique course. Although the course is now intended for electrical and computer engineering students only, its scope will be expanded to accommodate mechanical and other engineering students.

Student success was the motivation for evolving an individual project-based course into a project-centric curriculum. A one semester project was first extended across a sequence of three interrelated courses tied together through their focus on the success of small team projects that spanned those courses. This sequence was then targeted as the core of a redesign of the entire program curriculum focused on project and student success. Currently, the department is in the process of introducing the measurement of project success as a tool for assessment and control of the departments learning objectives. An overview of the design of this curriculum, lessons learned from developing it, and benefits of this type of curriculum in quality of student learning, community engagement, and reputation of the university, will be discussed.

A frictionless environment simulation platform, utilized for accomplishing three-axis attitude control tests in small satellites, is introduced. It is employed to develop, improve, and carry out objective tests of sensors, actuators, and algorithms in the experimental framework. Different sensors (i.e. sun, earth, magnetometer, and an inertial measurement unit) are utilized to assess three-axis deviations. A set of three inertial wheels is used as primary actuators for attitude control, together with three mutually perpendicular magnetic coils intended for desaturation purposes, and as a backup control system. Accurate balancing, through the platform’s center of mass relocation into the geometrical center of the spherical air-bearing, significatively reduces gravitational torques, generating a virtually torque-free environment. A very practical balancing procedure was developed for equilibrating the table in the local horizontal plane, with a reduced final residual torque. A wireless monitoring system was developed for on-line and post-processing analysis; attitude data are displayed and stored, allowing properly evaluate the sensors, actuators, and algorithms. A specifically designed onboard computer and a set of microcontrollers are used to carry out attitude determination and control tasks in a distributed control scheme. The main components and subsystems of the simulation platform are described in detail.

ABSTRACT The Algerian Space Agency has been active in the field of microsatellite engineering for more than 15 years and has successfully developed microsatellites under several know-how transfer technology programs, six to date. This paper presents the flight results and lessons learned from the attitude determination and control system (ADCS) flown on the ALSAT-2B satellite, an Earth observation microsatellite, by analysing the behaviour of the satellite from the initial attitude acquisition through the coarse pointing mode then the nominal mode, where the payload is first tested, and finally the orbit control mode. The spacecraft was launched on 26 September 2016 and placed into a 670km Sun-synchronous orbit with a solar local time at an ascending node of 22:15. The ADCS performance presented here mainly focuses on the launch and early operation results. ALSAT-2B includes four reaction wheels in a pyramidal configuration, three gyros, three Sun sensors, three magneto-torquers, one magnetometer, and one star tracker for agile and accurate attitude control. In addition, a propulsion system based on four 1N hydrazine thrusters is also used on board the microsatellite. The main new development in this platform compared with previous ones of the same type is the fusion of the star tracker and measurements by the three gyroscopes into one gyrostellar estimator that was implemented for the first time on ALSAT-2B, and the pyramidal configuration of the wheels, aiming to increase the angular momentum. The results obtained from the early launch operations for different ADCS modes are very encouraging and fulfil all the requirements set during design and testing. Currently, the satellite has accomplished its fourth year in orbit and is still operational and producing high-quality images.

This work aimed to analyse students’ conceptions in a graduate course of biology teachers at the University Centre of Formiga, Minas Gerais, Brazil, of topics related to evolutionary theory (Chance and Natural selection) and creationism (God and Intelligent design). We used a part of the European BIOHEAD-CITIZEN questionnaire in a sample of 56 students, studying in their 2nd, 4th and 6th terms. The four-category Barbour model (conflict, independence, dialogue and integration) was used to analyse the data and characterise the students’ ideas of the relationship between science and religion. Using the Pearson chi-square statistical test (χ2), the differences among the groups of students were tested, at the statistical significance level of 5%. The results show that most students are able to establish a relationship of independence between issues of evolutionary theory and creationism. Even religious students can establish boundaries that separate the fields of science and religion. Due to the importance of evolutionary theory for science and for biology in particular, it is necessary for new research to be carried out in the Brazilian context to determine students’ and teachers’ perceptions on the topic and to improve the teaching of evolutionary theory in the biological context and to refrain from inserting personal religious considerations into general science and biology classes.

Information Landscape

As the information landscape becomes increasingly complex, librarians must adapt accordingly. With information so readily available, students overestimate their research skills and lack awareness of how the library can help. However, librarians’ academic training makes them ideal resources to support students’ complex information needs - whether students know it or not. In this paper, we argue that embedded librarianship is the solution to this disconnect between librarian and user. Specifically, this paper provides case studies at two Canadian universities of librarians approaching embedded librarianship from different directions. At the University of Waterloo, two engineering librarians worked toward an embedded model of librarianship where this was not yet an established model in the Faculty of Engineering. At the University of Saskatchewan, a librarian was hired with the intention of the new position being embedded, without a formal structure or precedent for this within the College of Engineering.  The term “embedded librarian” describes a service model where an academic librarian participates in an academic course or program on a continuing basis in order to understand the learning objectives and determine which resources best support them. In order to “do this, the librarian has to be familiar with the work and understand the domain and goals. Doing this, the librarian becomes an invaluable member of the team” [1]. The variables associated with embeddedness include location, funding, management and supervision, and participation [1]. To this end, the authors explore how each of these variables contribute to the success of moving towards this embedded model: how moving out of the library influences overall connection, how they acquired funding to grow a new collection, how management supports the overall goal, and how sustained participation in the program grows new opportunities.  At both universities, librarians have seen most success embedding in programs with a strong emphasis on integrated STEM education where the focus is on providing real-world context with the aim of graduating well-rounded engineers [2]. The authors will discuss how programmatic learning outcomes and trends in integrated and interdisciplinary education have allowed them to stretch beyond the traditional boundaries of academic librarianship to demonstrate value to the Engineering departments in new ways.  This paper reports on the experiences, advantages, and lessons learned in moving toward this model, and provides concrete examples for adapting these concepts to programs at other institutions. Through an intrinsic case study [3] the authors aim to understand how librarians’ embeddedness can adapt and change to support student learning in different contexts. This session is targeted towards practicing engineering librarians and engineering faculty members and educators. Attendees will leave the session with ideas on how to stimulate new partnerships between their library and Engineering programs.

Students from Princeton University partnered with students from the American University in Cairo in a three-week intensive hands-on field experience in Egypt. The project was to assemble, install, and test a wind mill-driven pump used for irrigation and to survey communities across Egypt in the Delta and Red Sea coast to assess water needs in these communities. The course offered a perspective on sustainable development in Egypt followed by water and energy resource challenges in Egypt's diverse geographic areas. Students assembled a wind pump and installed it at the American University in Cairo for testing prior to installation at El Heiz, a desert oasis community in the Western Desert. The students were selected from diverse backgrounds in Mechanical and Aerospace Engineering, Civil and Environmental Engineering, Computer Engineering, and Operations Research and Financial Engineering, and learned the value of having diverse teams address engineering problems in a truly global context. This paper presents the case study including lessons learned in implementation of this experiential learning field project.

Abstract The Control community has recently witnessed an almost exponentially growing interest in the application of game-theoretic concepts and tools in research on control, multi-agent systems, and networks. In an interview with NSR, Professor Tamer Başar, a member of the US National Academy of Engineering, Swanlund Endowed Chair and CAS Professor of Electrical and Computer Engineering, and Director of the Center for Advanced Study at the University of Illinois at Urbana-Champaign in the USA, former president of both the IEEE Control Systems Society and the American Automatic Control Council, and the founding president of the International Society of Dynamic Games, talked about the recently emerging role of game theory in control and networking research, how it broadens the territorial boundaries of control into disciplines outside engineering, and opportunities and challenges that lie ahead.

Capstone projects offer an excellent oppor- tunity to assess the attributes of engineering students in their final year of studies. For the purposes of accredi- tation and outcomes assessment, capstone projects can be used to establish that engineering students have ob- tained a suitable level of mastery of the skills necessary to be successful in their field of study. At the University of Waterloo, a committee was formed by the Faculty of Engineering to investigate, develop, and implement a common set of rubrics for the purpose of consistently assessing graduate attributes across all engineering disciplines. Faculty members from every engineering discipline were appointed to the committee. Using the collective experience of the committee members, a set of rubrics for outcomes assessment was established. This paper examines the design of the six rubrics that the committee deemed to be equally applicable to all engineering disciplines. These rubrics assess the CEAB graduate attributes of problem analysis, design, individual and team work, communication skills, and economics and project management. Each rubric subdivides the assessment of an attribute into a set of elements that are examined independently. This paper presents the rubrics, examines the elements of each CEAB graduate attribute, and examines the expected level of mastery associated with each assessment level. This paper concludes with a discussion of the recent use of the rubrics in the assessment of capstone projects in the Department of Electrical and Computer Engineering.
