Bovay Program in the History and Ethics of Professional Engineering Cornell UniversityAbstractHow do we prepare engineering students to make ethical and responsible decisions in theirprofessional work? This paper presents an approach that enhances engineering students’engagement with ethical reasoning by simulating decision-making in a complex scenario. Theapproach has two principal inspirations.

According to Engineers Canada, only 1 percent ofundergraduate engineering students enrolled in accredited engineering programs in Canadaidentify as an Indigenous person and Indigenous peoples represent only 0.73 percent ofprofessional engineers in Canada (Engineers Canada, 2020). Addressing inequities in ourcurrent educational system in the areas of STEM education are complex includingintersectional variables such as stereotypes, bias, racism, sexism, ableism, operational andprocess structures, and socioeconomic challenges. (Tefera et al., 2018) While it is importantto understand why we have these disparities and inequities, it is important to discover ways toinnovate potential solutions to the system

Missouri State University (MSU) signed a Memorandumof Understanding that allowed Missouri S&T to offer bachelor’s degrees in Civil and ElectricalEngineering on the MSU campus. The first classes in the new cooperative program were held onthe MSU campus in the fall of 2008. In the spring of 2012 fifteen students completed theprogram and became the first graduates.In this paper, the authors take a look back at the program to identify successes and problems aswell as strengths and weaknesses over these first four years. Hopefully this will be of interest tothose involved in similar problems.Overview – Major Milestones 1. August 2006 Memorandum of Understanding between Missouri S&T and MSU signed. 2.

the electromagnetic immunity of digital ICs could help the IC designer build betterICs and help the board designer build better systems that use these ICs, but unfortunately suchmodels are not widely available. A test IC containing components common to all digital ICs wasbuilt to help develop immunity modeling strategies (Figure 1). One component in test IC is anSRAM circuit, which requires many digital signals to properly read and write values frommemory. A method was needed for generating and reading the digital signals to and from theFPGA at high speeds. Digital signals were generated with a Cyclone III FPGA developmentboard with an external clock speed of 50 MHz. The switching frequency of the signals had to bearound 400 MHz, which is

To compound the issue, instructors in the “hard” disciplines deal with instructional 2material that lends itself to a more “teacher-centered” approach to learning where transmission ofinformation and worked examples are the highest goal.1 However, some research studies havefound that this approach is linked more to surface learning. Deeper learning has been linked to amore “student-focused/conceptual change” approach, more regularly seen with instructors in thehumanities and soft sciences. 2At a land-grant, research-intensive

well at low frequencies [1]. Optimization of the antenna design would force a compromise between frequency bandwidth (range resolution) and angular resolution. The upper bound of this frequency band was limited by the available instrumentation (a vector network analyzer), and the lower bound was limited by the size of the antenna. The frequency band of 1 - 6 GHz was chosen as an optimal solution to the requirements. This frequency band also achieved the acceptable compromise between the required resolution and penetration depth due to the size limitations of the array. Once the operating points of the antenna array were determined, a suitable antenna design was sought. In this case, a Vivaldi antenna design (an endfire, tapered-slot

While this design provided a reduction in dragcompared to fuselages with a non-circular frontal area, there were some issues with the design.A full-walled cylindrical tube made access to the various electronics in the front of the aircraftdifficult. Attaching the wing and landing gear to the fuselage also became difficult due to thelack of flat surfaces. This issue will be discussed further in the landing gear section. The 2011fuselage had a wall thickness of less than 1/8 inch, an outer diameter of four inches, a length of20.25 inches, and weighed two pounds. While
