Towards A Pedagogy Of Comparative Visualization In 3d Design Disciplines, James Birt, Jonathan Nelson, Dirk Hovorka Mar 2016

Towards A Pedagogy Of Comparative Visualization In 3d Design Disciplines, James Birt, Jonathan Nelson, Dirk Hovorka

Jonathan J Nelson

Spatial visualization and interpretation are important skills for designers. However, these skills generally require significant experiential development over the course of years. Visualizations allow the human brain to convey complex spatial concepts in intuitive, navigable and manipulable forms improving learner outcomes and perceptions. But often these visualizations are studied as single modality solutions. Dual modality and multimedia presentation studies show positive improvements in learner outcomes but dual modality is often difficult to compare. This paper presents ongoing research in the use of comparative multimodal visualizations produced with emerging technology solutions in 3D Design classrooms. Presented are previous findings from multimedia …


Intelligent Systems Development In A Non Engineering Curriculum, Emily Brand, William Honig, Matthew Wojtowicz Feb 2016

Intelligent Systems Development In A Non Engineering Curriculum, Emily Brand, William Honig, Matthew Wojtowicz

William L Honig

Much of computer system development today is programming in the large - systems of millions of lines of code distributed across servers and the web. At the same time, microcontrollers have also become pervasive in everyday products, economical to manufacture, and represent a different level of learning about system development. Real world systems at this level require integrated development of custom hardware and software.

How can academic institutions give students a view of this other extreme - programming on small microcontrollers with specialized hardware? Full scale system development including custom hardware and software is expensive, beyond the range of any …


Teaching And Assessing Programming Fundamentals For Non Majors With Visual Programming, William Honig Feb 2016

Teaching And Assessing Programming Fundamentals For Non Majors With Visual Programming, William Honig

William L Honig

Visual programming tools and mobile device applications are a natural tool to engage university students; but, are they effective in teaching quantitative thinking skills to non computer science majors? Answering this question can be based on careful assessment of the learning outcomes. This paper reports the results from teaching over 100 students mobile app development with App Inventor in a university core course. Results were measured using an assessment process motivated by Bloom's Taxonomy that included student self assessment, ratings by instructors, and comparisons of the two results. The categories in the assessment were mapped to specific levels of skills …


Precis: A Design-Time Precision Analysis Tool, Mark L. Chang, Scott Hauck Jul 2012

Precis: A Design-Time Precision Analysis Tool, Mark L. Chang, Scott Hauck

Mark L. Chang

Currently, few tools exist to aid the FPGA developer in translating an algorithm designed for a general-purpose-processor into one that is precision-optimized for FPGAs. This task requires extensive knowledge of both the algorithm and the target hardware. We present a design-time tool, Precis, which assists the developer in analyzing the precision requirements of algorithms specified in MATLAB. Through the combined use of simulation, user input, and program analysis, we demonstrate a methodology for precision analysis that can aid the developer in focusing their manual precision optimization efforts.


Low-Cost Stereo Vision On An Fpga, Chris A. Murphy, Daniel Lindquist, Ann Marie Rynning, Thomas Cecil, Sarah Leavitt, Mark L. Chang Jul 2012

Low-Cost Stereo Vision On An Fpga, Chris A. Murphy, Daniel Lindquist, Ann Marie Rynning, Thomas Cecil, Sarah Leavitt, Mark L. Chang

Mark L. Chang

We present a low-cost stereo vision implementation suitable for use in autonomous vehicle applications and designed with agricultural applications in mind. This implementation utilizes the Census transform algorithm to calculate depth maps from a stereo pair of automotive-grade CMOS cameras. The final prototype utilizes commodity hardware, including a Xilinx Spartan-3 FPGA, to process 320times240 pixel images at greater than 150 frames per second and deliver them via a USB 2.0 interface.


Model Checking In The Absence Of Code, Model And Properties, David Lo, Siau-Cheng Khoo Nov 2011

Model Checking In The Absence Of Code, Model And Properties, David Lo, Siau-Cheng Khoo

David LO

Model checking is a major approach in ensuring software correctness. It verifies a model converted from code against some formal properties. However, difficulties and programmers ’ reluctance to formalize formal properties have been some hurdles to its widespread industrial adoption. Also, with the advent of commercial off-the-shelf (COTS) components provided by third party vendors, model checking is further challenged as often only a binary version of the code is provided by vendors. Interestingly, latest instrumentation tools like PIN and Valgrind have enable execution traces to be collected dynamically from a running program. In this preliminary study, we investigate what can …


Mining Scenario-Based Specifications With Value-Based Invariants, David Lo, Shahar Maoz Nov 2011

Mining Scenario-Based Specifications With Value-Based Invariants, David Lo, Shahar Maoz

David LO

There have been a number of studies on mining candidate specifications from execution traces. Some extract specifications corresponding to value-based invariants, while others work on inferring ordering constraints. In this work, we merge our previous work on mining scenario-based specifications, extracting ordering constraints in the form of live sequence charts (LSC), a visual specification language, with Daikon, a tool for mining value-based invariants. The resulting approach strengthens the expressive power of the mined scenarios by enriching them with scenario-specific value-based invariants. The concept is illustrated using a preliminary case study on a real application.
