Course Outcome Prediction Using An Expert System, Michael Kuehn, Jared Estad, Jeremy Straub, Eunjin Kim Apr 2015

Course Outcome Prediction Using An Expert System, Michael Kuehn, Jared Estad, Jeremy Straub, Eunjin Kim

Jeremy Straub

Determining how well a student will perform in a course based on their prior knowledge of the course material and other factors may help determine student placement and the need for remedial instruction. This poster presents work on the creation of an expert system that attempts to predict a student’s performance based on a pre-evaluation test and responses to background preparation questions. This work utilizes data from prior students to train and test the system.


Classroom Polling Software For Use With Mobile And Web-Based Devices, Nick Renford, Jeremy Straub, Scott Kerlin Apr 2014

Classroom Polling Software For Use With Mobile And Web-Based Devices, Nick Renford, Jeremy Straub, Scott Kerlin

Jeremy Straub

The goal of this project is to create an interface for Android, iOS, and Win-dows Phone smartphones, as well as a web interface that will act as a “clicker”. The instructors will be able to send out questions, and the students will be able to answer the questions, and get feedback if the instructor wants them to have it. The teacher can decide whether the feedback is instant or manually initiated, and what format the response will be, whether it includes the correct answer, and what type of chart, if any, indicating the most com-monly selected answer(s). There will be …


The Use Of Solar Balloons At Und As A Low-Cost Alternative To Helium Balloons For Small Spacecraft Testing And Stem Education, John Nordlie, Jeremy Straub, Chris Theisen, Ronald Marsh Mar 2014

The Use Of Solar Balloons At Und As A Low-Cost Alternative To Helium Balloons For Small Spacecraft Testing And Stem Education, John Nordlie, Jeremy Straub, Chris Theisen, Ronald Marsh

Jeremy Straub

Helium-filled latex weather balloons have been utilized for many years to carry small satellite prototypes and subsystems into the stratosphere to allow testing in a “near space” (stratospheric) environment. A variety of environmental factors similar to the space environment can be found in this region, such as a rarified atmosphere, increased thermal stress including very low temperatures, increased solar radiation, the necessity of remote command and control, tracking, and telemetering of data. While this method of flight testing has been well-proven, a recent increase in the price of helium has driven the cost of such test programs to much higher …


The Use Of The Roofsat For Computer Science And Engineering Education, Jeremy Straub, Ronald Marsh Mar 2014

The Use Of The Roofsat For Computer Science And Engineering Education, Jeremy Straub, Ronald Marsh

Jeremy Straub

This poster presents an overview of a tool that has been created to provide students with real-world experience in the design, development and operation of control and scientific mission software for a cyber-physical system. The ROOFSAT, developed at UND, is a low-cost analog for a small spacecraft (though in many ways these capabilities also enable similar UAV work). The ROOFSAT was constructed with approximately $1,500 generously provided by the John D. Odegard School of Aerospace Sciences out of commercially-available parts. It includes multiple cameras, a pan-tilt mount and the same space-qualified computer hardware which has been used on both spacecraft …


Roofsat: Teaching Students Skills For Software Development For Gis Data Collection And Other Activities, Jeremy Straub, Ronald Marsh, Donovan Torgerson, Christoffer Korvald Dec 2013

Roofsat: Teaching Students Skills For Software Development For Gis Data Collection And Other Activities, Jeremy Straub, Ronald Marsh, Donovan Torgerson, Christoffer Korvald

Jeremy Straub

Small Spacecraft provide an excellent platform for the collection of geospatial data. In order to enable the low-cost creation of small remote sensing space-craft in a university environment, a training pathway for students is required. The Realistic Operational Ob-ject for Facilitating Software Assessment and Testing (RoofSat) serves to provide students with experience developing software for a small satellite platform typi-cal of those used for remote sensing missions. It al-lows software to be tested with hardware that re-sponds in a similar manner to that found on the satel-lite for a fraction of the cost of development. This poster details the goals …


A Review Of Online Collaboration Tools Used By The Und Openorbiter Program, Jeremy Straub, Christoffer Korvald May 2013

A Review Of Online Collaboration Tools Used By The Und Openorbiter Program, Jeremy Straub, Christoffer Korvald

Jeremy Straub

The OpenOrbiter program at the University of North Dakota is a student-initiated, student-run effort to design, develop, test, launch and operate a CubeSat-class spacecraft to validate the designs of the Open Prototype for Educational NanoSatellites (a framework that will be made publically-available to allow faster and lower-cost missions at other educational institutions worldwide). OpenOrbiter involves (at various participation levels) over 200 faculty and students spanning five colleges and ten departments. To coordinate this large group of participants who comprise over seventeen teams and work at disjoint hours in a plethora of locations, online project management, software source control and hardware …


The International Trafficking In Arms Regulations: Precluding Innovation In Academic Spacecraft Engineering — Or Are They?, Jeremy Straub, Joe Vacek Feb 2013

The International Trafficking In Arms Regulations: Precluding Innovation In Academic Spacecraft Engineering — Or Are They?, Jeremy Straub, Joe Vacek

Jeremy Straub

Government regulations and uncertainty about their enforcement can be a significant barrier to innovation. In business, it is undesirable to consume time and other resources developing a product that cannot be sold or which requires navigating significant bureaucracy for each sale. In academ-ia, where limited funding is available prior to the submission of a grant pro-posal and receipt of an award, proposal-stage compliance costs can derail a project long before it begins. This paper reviews the International Traffick-ing in Arms Regulations (ITAR) and their impact on spacecraft research in academia, private research labs and industry. It reviews the exemptions available, …


Formalizing Mission Analysis And Design Techniques For High Altitude Ballooning, Jeremy Straub, Ronald Fevig Jun 2012

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 …
