Work In Progress - Using Video And Self-Reflection To Enhance Undergraduate Teams, Nick Tatar, Debbie Chachra, Yevgeniya Zastavker, Jonathan Stolk
Debbie Chachra
Engineers today must be able to communicate and collaborate in teams. They also must be comfortable making adjustments within the team to maintain flow and progress toward project goals. With these goals in mind, students in a first-semester engineering seminar course were asked to videotape a team meeting in their design course and to write a self-reflection paper after viewing their video. After analyzing the video, students were asked to provide clear suggestions in their self-reflection paper for improving their own and their team's performance. Our preliminary analysis showed that video-supported reflections: 1) may be more effective than memory for …

Drowning In Method, Thirsty For Values: A Call For Cultural Inquiry, Jonathan Stolk, Mark Somerville, Debbie Chachra
Debbie Chachra
A decade or more has passed since publication of most calls for reform in engineering education. In the ensuing time, there has been significant work on the design, implementation, and transferability of appropriate methodsand techniques - accompanied by, in most cases, little discussion of the values and beliefs of the people involved. But many theories of change rely on a fundamental shift in human beliefs and values, and purport that institutionalization of methods is impossible without this shift. Given this, now may be a reasonable time to re-visit the questions: What are the values of people involved in engineering education, …

A Semi-Automatic Approach For Project Assignment In A Capstone Course, Mark Chang, Allen Downey
A Semi-Automatic Approach For Project Assignment In A Capstone Course, Mark Chang, Allen Downey
Mark L. Chang
This paper presents a semi-automatic approach to assigning students to project teams for a year-long, industry-sponsored senior capstone course. Successful assignment requires knowl- edge of at least individual project requirements, student skills, student personalities, and student project preferences. This mix of hard skills, soft skills, and interpersonal impres- sions requires human involvement to produce a high-quality assignment. The importance of faculty input often requires that the assignment process be labor- and time-intensive.
Our approach attempts to reduce the time required to perform this assignment by selectively automating parts of the task flow. An automated search uses a randomized greedy algorithm …

A Blank Slate: Creating A New Senior Engineering Capstone Experience, Mark L. Chang, Jessica Townsend
Mark L. Chang
This paper presents some of the challenges, successes, and experiences in designing a new senior engineering capstone program at the Franklin W. Olin College of Engineering. Senior capstone design programs in engineering colleges have evolved over many years and are often modified and reinvented to keep up with the needs of both students and external constituencies. Harvey Mudd College’s Clinic program is one of the largest and longest-running capstone programs in the country that relies heavily on industry sponsors to provide real world problems and funding to execute the projects. For many reasons, and in no small way because of …

Work In Progress - Impact Of Early Design Instruction On Capstone Experiences, Mark L. Chang, Jessica Townsend
Mark L. Chang
In the Olin College curriculum, students have significant, early, and continuous exposure to user-oriented design principles. As a result, our students have a very user-centered approach to problem solving that has affected our yearlong, industry-sponsored capstone in several ways. We have reflected on five years of capstone engagements in order to learn how our program has changed because of the design emphasis in our curriculum. The significance of our work is to inform the many departments that are already undertaking design-centric curriculum reform on how they may modify their capstone experiences to best take advantage of new student understanding, and …

'Kinetic Sculptures': A Centerpiece Project Integrated With Mathematics And Physics, Yevgeniya Zastavker, Jill Crisman, Mark Jeunnette, Burt Tilley
'Kinetic Sculptures': A Centerpiece Project Integrated With Mathematics And Physics, Yevgeniya Zastavker, Jill Crisman, Mark Jeunnette, Burt Tilley
Yevgeniya V. Zastavker
An integrated set of courses, or Integrated Course Block (ICB), developed for incoming first-year students at the Franklin W. Olin College of Engineering, is presented. Bound by a common theme of `Kinetic Sculptures', the individual courses in this ICB are mathematics (single variable calculus and ordinary differential equations), physics (kinetics and dynamics of linear and rotational motion, thermodynamics and fluids), and an open-ended engineering project. The project part of the ICB allows students to explore the motion through the design of kinetic (moving) sculptures while utilizing the mathematics and physics concepts learned in the accompanying courses. This paper considers the …

Faculty On Integrated Project-Based Learning, Yevgeniya Zastavker, Casey Canfield
Yevgeniya V. Zastavker
This paper examines the experiences, perspectives, and concerns of faculty involved in implementing a first-year integrated project-based engineering curriculum as they attempt to understand and reconcile their own and students’ views, attitudes, and beliefs regarding project-based learning (PjBL). A semi-structured, open-ended interview protocol is employed with seven mathematics and physics faculty participants. Grounded theory is used to identify the following themes: divergence of faculty perceptions regarding the effectiveness of an integrated approach in teaching and learning, the value of projects, and conflicting student expectations.

Capacitively Coupled Radio-Frequency Discharges In Nitrogen At Low Pressures, L. L Alves, L. Marques, C. D Pintassilgo, W. Wattieaux, Et. Es-Sebbar, J. Berndt, E. Kovačević, N. Carrasco, L. Boufendi, G. Cernogora
Dr. Et-touhami Es-sebbar
This paper uses experiments and modelling to study capacitively coupled radio-frequency (rf) discharges in pure nitrogen, at 13.56 MHz frequency, 0.1–1 mbar pressures and 2–30 W coupled powers. Experiments performed on two similar (not twin) setups, existing in the LATMOS and the GREMI laboratories, include electrical and optical emission spectroscopy (OES) measurements. Electrical measurements give the rf-applied and the direct-current-self-bias voltages, the effective power coupled to the plasma and the average electron density. OES diagnostics measure the intensities of radiative transitions with the nitrogen second-positive and first-negative systems, and with the 811.5 nm atomic line of argon (present as an …

Dicko Prof., Bertrand M’Batchi
Pr. Mamoudou H. DICKO, PhD
The present study reports the antibacterial capacity of alkaloid compounds in combination with Methicillin and Ampicillin-resistants bacteria isolated from clinical samples. The resistance of different bacteria strains to the current antibacterial agents, their toxicity and the cost of the treatment have led to the development of natural products against the bacteria resistant infections when applied in combination with conventional antimicrobial drugs. The antibacterial assays in this study were performed by using inhibition zone diameters, MIC, MBC methods, the time-kill assay and the Fractional Inhibitory Concentration Index (FICI) determination. On the whole, fifteen Gram-positive bacterial strains (MRSA/ARSA) were used. Negative control …

Ionization Photophysics And Rydberg Spectroscopy Of Diacetylene, M. Schwell, Y. Benilan, N.. Fray, M.-C. Gazeau, Et. Es-Sebbar, F.-G. Levrel, N. Campion, S. Leach
Dr. Et-touhami Es-sebbar
Photoionization of diacetylene was studied using synchrotron radiation over the range 8–24 eV, with photoelectron-photoion coincidence (PEPICO) and threshold photoelectron–photoion coincidence (TPEPICO) techniques. Mass spectra, ion yields, total and partial ionization cross-sections were measured. The adiabatic ionization energy of diacetylene was determined as IEad = (10.17 ± 0.01) eV, and the appearance energy of the principal fragment ion C4H+ as AE = (16.15 ± 0.03) eV. Calculated appearance energies of other fragment ions were used to infer aspects of dissociation pathways forming the weaker fragment ions , C3H+, and C2H+. Structured autoionization features observed in the PEPICO spectrum of diacetylene …

The North Dakota Space Robotics Program: Teaching Spacecraft Development Skills To Students Statewide With High Altitude Ballooning, Jeremy Straub, Ronald Fevig
Jeremy Straub
The University of North Dakota is serving as the lead institution in a statewide effort to develop student spacecraft engineering skills. This effort, which is part of the North Dakota Space Robotics Program (NDSRP), provides students the ability to participate in the design, development and fabrication of a small satellite analog that is launched by a high altitude balloon. The first iteration of the NDSRP Near-Spacecraft Project is generating a functional prototype of a remote sensing payload, which will perform onboard image processing. This project included undergraduate and graduate students from two institutions and five different academic departments. The students …

Formalizing Mission Analysis And Design Techniques For High Altitude Ballooning, Jeremy Straub, Ronald Fevig
Jeremy Straub
High altitude balloon (HAB) missions can be and are used to teach concepts related to spacecraft and satellite design. A HAB mission, however, presents unique characteristics, which must be understood and respected to produce a desirable outcome. Because of this, flying an unaltered satellite design as a HAB payload would be as undesirable as utilizing an unaltered HAB design as a satellite. A well-defined process for HAB mission design is thus needed. The process presented mirrors commonly used space mission design processes to facilitate easy transition between the two. It is also comparatively simple, due to the smaller scale of …

Shweta Chopra
Numerous reports have discussed the dearth of women in Science, Technology, Engineering; Mathematics (STEM) fields. Almost two-thirds of young children of age group 9-15 state that they enjoy science, but girls’ attitudes and interests change by middle school. During high school, girls and boys take the same number of science courses. In addition, girls perform as well as boys in those courses. Despite comparable performance levels, girls rarely continue studying science at college level. Lack of female progress in STEM education has been observed in STEM fields despite multiple measures taken by universities, colleges, schools, industries, and other organizations dedicated …

Emp And Geomagnetic Storm Protection Of Critical Infrastructure, George H. Baker Iii
Emp And Geomagnetic Storm Protection Of Critical Infrastructure, George H. Baker Iii
George H Baker
EMP and solar storm wide geographic coverage and ubiquitous system effects beg the question of “Where to begin?” with protection efforts. Thus, in addressing these “wide area electromagnetic (EM) effects,” we must be clever in deciding where to invest limited resources. Based on simple risk analysis, the electric power and communication infrastructures emerge as the highest priority for EM protection. Programs focused on these highest risk infrastructures will go a long way in lessoning societal impact. Given the national scope of the effects, such programs must be coordinated at the national level but implemented at local level. Because wide-area EM …

A Critical Perfomance Analysis Of Thin Client Platforms, Faith J. Shimba, Renatus Michael
Faith Joel Shimba
The nature of operation of Thin Client computing makes their performance to be affected by both the quality of the network and the terminals. For the past few years, there are few analyses on the performance of Thin Clients that can produce reliable, valid, and up-to-date results collected in a well designed and evaluated experiment based research. This paper analyses the performance of Thin Clients through experiment based research. The approach is to use benchmark application which is designed specifically for measurement of desktop computers by inserting delays in the visual elements of such benchmark application. In this technique, packet’s …

Rethinking Cs101: Or, How Robots Revolutionize Introductory Computer Programming, Lynn Stein
Lynn Andrea Stein
Introductory computer science education is entrenched in an outdated computational model. Although it corresponds neither to our computing environments nor to our work, we insist on teaching our introductory students computation-as-calculation, a mathematical problem-solving view of the role of the computer program. We can dramatically improve this situation -- and, as a corollary, all of undergraduate computer science -- by focusing on the kind of dynamic, interactive, inherently parallel computation that occurs in spreadsheets and video games, web applications and robots.

Jonathan Stolk
Against a backdrop of compelling societal needs, graduates in science and engineering now must master their disciplines and demonstrate a sophisticated level of cognitive, affective and social development. This has lead a number of national and international commissions on science and engineering to urge educators to re-think the way in which STEM disciplines are taught. We have chosen to “repackage” a traditional undergraduate materials engineering curriculum in a form designed to promote the development of higher-order cognitive skills like self-directed learning and design. Classic metallurgy experiments have been converted to project-based learning experiences where students are put in the role …

The Search For Design In Electrical Engineering Education, David V. Kerns, Sherra E. Kerns, Mark Somerville, Gill Pratt, Jill Crisman
Sherra E. Kerns
The importance of "design" in engineering education is well established and a cornerstone of most new engineering curricula as well as accreditation criteria Electrical and computer engineering (ECE) programs view many elements of design in ways similar to other engineering disciplines. However, in some respects other disciplines within engineering, such as Mechanical Engineering (ME), view design in broader terms, and perhaps gain value that electrical and computer engineering educators may miss. This paper describes how design is typically viewed in ECE programs, bow it's viewed in other engineering areas, particularly ME, and suggests some new possibilities for enhancing design education …

Janet M. Callahan
During Fall semester of 2007, a semester-long, quasi-experimental study was conducted at Boise State University to investigate the effectiveness of a systematically sequenced and managed, self-paced e-learning activity on improving students’ academic performance and motivation. A total of 125 students enrolled in 3 different sections of a Precalculus class participated in the study. The e-learning activity was implemented in 2 of the 3 sections as a required homework assignment. Students enrolled in one of the 2 selected sections were all engineering majors. The 3rd section was a control group that did not use the e-learning activity. A pre-test, measuring …

Dr. Et-touhami Es-sebbar
A quantitative agreement between nitrile relative abundances and Titan’s atmospheric composition was recently shown with a reactor simulating the global chemistry occurring in Titan’s atmosphere [Gautier et al. (2011) Icarus, 213: 625]. Here we present a complementary study on the same reactor using an in-situ diagnostic of the gas phase composition. Various initial N2-CH4 gas mixtures (methane varying from 1 to 10%) are studied, with a monitoring of the methane consumption and of the stable gas neutrals by in-situ mass spectrometry. Atomic hydrogen is also measured by optical emission spectroscopy. A positive correlation is found between atomic hydrogen abundance and …
