Enhancing The Engineering Curriculum: Defining Discovery Learning At Marquette University, Jay R. Goldberg, Mark L. Nagurka
Enhancing The Engineering Curriculum: Defining Discovery Learning At Marquette University, Jay R. Goldberg, Mark L. Nagurka
Biomedical Engineering Faculty Research and Publications
This paper summarizes the results of our investigation into the feasibility of increasing the level of discovery learning in the College of Engineering (COE) at Marquette University. We review the education literature, document examples of discovery learning currently practiced in the COE and other schools, and propose a Marquette COE-specific definition of discovery learn-ing. Based on our assessment of the benefits, costs, and tradeoffs associated with increasing the level of discovery learning, we pre-sent several recommendations and identify resources required for implementation. These recommendations may be helpful in enhancing engineering education at other schools.

Powered Transtibial Prosthetic Device Control System Design, Implementation And Testing, Jinming Sun
Master's Theses (2009 -)
A powered lower limb prosthesis, which consists of a four bar mechanism, a torsional spring and a brushed DC motor, was previously designed and fabricated. To regulate the motor power input, a two level controller was proposed and built. The control algorithm includes a higher level finite state controller and lower level PID controllers. To implement the control system, a digital signal processor (DSP) control board and MATLAB Simulink were used to realize the higher level control and a DC motor controller was used to realize the lower level PID control. Sensors were selected to provide the required feedback. The …
Mechanism State Matrices For Spatial Reconfigurable Mechanisms, Philip A. Voglewede, Brian Korves, Brian Slaboch
Mechanism State Matrices For Spatial Reconfigurable Mechanisms, Philip A. Voglewede, Brian Korves, Brian Slaboch
Mechanical Engineering Faculty Research and Publications
This paper improves augmented mechanism state matrices by replacing joint code with screw system notation. The proposed substitution allows for a more specific description of the joints in the mechanism and the capability to describe both spatial and planar mechanisms. Examples are provided which elucidate the proposed approach.

Ergonomic Design Of An Aerial Bucket For Ingress And Egress, Bianca M. Bain
Ergonomic Design Of An Aerial Bucket For Ingress And Egress, Bianca M. Bain
Master's Theses (2009 -)
Electric utility companies across the US have been using aerial bucket trucks for line work and troubleshooting for decades. The use of these trucks eliminates the need for workers to climb utility poles in order to repair or maintain lines. Poor ingress and egress design can lead to acute injuries (slips and falls) as well as cumulative injury (musculoskeletal disorders (MSDs)). Utility companies want to know the best combination of steps and handlebars for aerial bucket ingress and egress that would minimize the risk of injury. American National Standards Institute (ANSI) standard – ANSI/SIA A92.2-2009, sets design requirements for aerial …
Are Posture Data From Simulated Tasks Representative Of Field Conditions? Case Study For Overhead Electric Utility Workers, Cristiane Shinohara Moriguichi, Leticia Carnaz, Luiz Carlos De Miranda Jr, Richard W. Marklin, Helenice Jane Cote Gil Coury
Are Posture Data From Simulated Tasks Representative Of Field Conditions? Case Study For Overhead Electric Utility Workers, Cristiane Shinohara Moriguichi, Leticia Carnaz, Luiz Carlos De Miranda Jr, Richard W. Marklin, Helenice Jane Cote Gil Coury

Many ergonomics studies are conducted in laboratory-simulated work environments to assess risks for the development of musculoskeletal disorders under more controlled conditions. However, the simulated conditions could be of questionable validity with respect to reproduction of field conditions involving risk factors. The objective of this study was to verify whether the postures recorded for neck extension/flexion and upper arm elevation of overhead electric utility workers in a simulated environment were similar to those recorded in a field environment. Of the three frequently performed tasks analysed, two presented similar exposure in both conditions. However, differences were identified for a more complex …
An In Vitro Comparative Study Of Intracanal Fluid Motion And Wall Shear Stress Induced By Ultrasonic And Polymer Rotary Finishing Files In A Simulated Root Canal Model, Jon Koch, John Borg, Abby Mattson, Kris Olsen, James Bahcall
An In Vitro Comparative Study Of Intracanal Fluid Motion And Wall Shear Stress Induced By Ultrasonic And Polymer Rotary Finishing Files In A Simulated Root Canal Model, Jon Koch, John Borg, Abby Mattson, Kris Olsen, James Bahcall
Mechanical Engineering Faculty Research and Publications
Objective. This in vitro study compared the flow pattern and shear stress of an irrigant induced by ultrasonic and polymer rotary finishing file activation in an acrylic root canal model. Flow visualization analysis was performed using an acrylic canal filled with a mixture of distilled water and rheoscopic fluid. The ultrasonic and polymer rotary finishing file were separately tested in the canal and activated in a static position and in a cyclical axial motion (up and down). Particle movement in the fluid was captured using a high-speed digital camera and DaVis 7.1 software. The fluid shear stress analysis was …
