On A Wing And A Strap, Tim Brady
In 1958, as part of Operation Jingle Bells, a Hercules C-130, ferrying cargo and personnel to the United States from the Far East, encountered weather and abbreviated their flight into Langley. Little Rock Air Force Base was chosen as the alternative landing site. Getting the C-130 down onto the ground proved to be challenging when the controls for the trim system did not operate correctly. Through sweat and ingenuity, the crew got the bird landed and the personnel in the back applauded their efforts. The personnel and cargo were used as ballast to change the center of gravity. After that ...

Sarah M. Ryan
We are developing a new learning environment that supports a suite of interrelated modules based on real-world scenarios. The primary goals of the project are to integrate industrial engineering courses, improve students’ information technology skills, and enhance students’ problem solving skills. In particular, metacognitive abilities will be strengthened as students apply domain knowledge, data, methods and software tools while monitoring their own solution processes. This paper presents the design of two modules that have been developed.
Scaffolding To Improve Reasoning Skills In Problem Formulation, 2017 Iowa State University
Scaffolding To Improve Reasoning Skills In Problem Formulation, John K. Jackman, Sarah M. Ryan, Craig A. Ogilvie, Dale Niederhauser
Sarah M. Ryan
Scaffolding to Improve Reasoning Skills in Problem Formulation Abstract Educators in engineering and science disciplines are well aware of student difficulties in formulating problems. Correct problem formulation is a critical phase in the problem solving process because the solution follows directly from the formulation. Students in this phase are engaged in reasoning and argumentation activities that result in support for a specific formulation. Empirical evidence from our work in ill-structured STEM problem solving indicate that more research is needed to understand the nature of problem formulation and what the cognitive challenges are for STEM students. Students work in teams to ...
Engineering Problem Solving In Industrial Engineering Curriculum Reform, 2017 Iowa State University
Engineering Problem Solving In Industrial Engineering Curriculum Reform, Veronica J. Dark, Frank Peters, Sarah M. Ryan, John K. Jackman, Sigurdur Olafsson
Sarah M. Ryan
Problem solving is a major focus of the engineering profession, and upon graduation new engineers are faced with increasingly complex problems. Yet, existing engineering education practices often fall short in preparing students to tackle complex engineering problems that may be ambiguous, open-ended and ill-structured. In this paper, we describe a newly developed learning environment called the Engineering Learning Portal (ELP), which focuses on improving engineering problem solving throughout the industrial engineering curriculum. In the ELP, students are engaged in a structured process for solving unstructured problems while encouraging metacognitive activities, such as planning, monitoring, and evaluating. This helps students acquire ...
Recombinant Aav Serotype And Capsid Mutant Comparison For Pulmonary Gene Transfer Of Alpha-1-Antitrypsin Using Invasive And Noninvasive Delivery, Rejean Liqun Wang, Thomas J. Mclaughlin, Travis Cossette, Qiushi Tang, Kevin Foust, Martha Campbell-Thompson, Ashley Martino, Pedro Cruz, Scott Loiler, Christian Mueller, Terence R. Flotte
Recombinant adeno-associated viral (rAAV) vectors have been widely used in pulmonary gene therapy research. In this study, we evaluated the transduction and expression efficiencies of several AAV serotypes and AAV2 capsid mutants with specific pulmonary targeting ligands in the mouse lung. The noninvasive intranasal delivery was compared with the traditional intratracheal lung delivery. The rAAV8 was the most efficient serotype at expressing alpha-1-antitrypsin (AAT) in the lung among all the tested serotypes and mutants. A dose of 1 x 1010 vg of rAAV8-CB-AAT transduced a high percentage of cells in the lung when delivered intratrachealy. The serum and the broncho-alveolar ...

A Simple Electric Field Probe In A Gauss's Law Laboratory, Daniel O. Ludwigsen, Gregory N. Hassold
Early in our calculus-based introductory course, students are introduced to electric fields and sometimes struggle with the abstraction of a vector field. They have less familiarity with the phenomena associated with electric fields, and the connection between phenomena and mathematical formalism is weaker. Our very next topic is Gauss's law.
Length And Floor Construction Of Dairy Stalls, 2017 Iowa State College
Length And Floor Construction Of Dairy Stalls, Henry Giese, C. Y. Cannon
Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)
One of the problems confronting the designer of a dairy barn is to determine the proper length of the stall platform. Cows vary considerably in length, and the stall length should vary to to meet the requirements of individual cows. Stalls that are too short make uncomfortable beds, force the cows to stand with one or both hind feet in the gutter and cause them, in reaching for hay in the manger, to carry manure to the stall floor. Long stalls are equally objectionable as the droppings fall on the platform rather than in the gutter. Adjustable stanchions are available ...

Hybrid buoyant aircraft are possible substitutes for jet and turbo-propeller aircraft currently utilized in aviation, and this manuscript is a country-specific (Malaysia) analysis to determine their potential market, assessing the tourism, business, agricultural, and airport transfer needs of such vehicles. A political, economic, social, and technological factors (PEST) analysis was also conducted to determine the impact of PEST parameters on the development of buoyant aircraft and to assess all existing problems ...
The Effect Of A Lower Extremity Kinematic Constraint On Lifting Biomechanics, 2017 Iowa State University
The Effect Of A Lower Extremity Kinematic Constraint On Lifting Biomechanics, Sangeun Jin, Gary A. Mirka
Gary A. Mirka
Leaning against a stationary barrier during manual materials handling tasks is observed in many industrial environments, but the effects of this kinematic constraint on low back mechanics are unknown. Thirteen participants performed two-handed lifting tasks using both a leaning posture and no leaning posture while trunk kinematics, muscle activity and ground reaction force were monitored. Results revealed that lifting with the leaning posture required significantly less activity in erector spinae (26% vs. 36% MVC) and latissimus dorsi (8% vs. 14% MVC), and less passive tissue moment compared with the no leaning posture. Peak sagittal accelerations were lower when leaning, but ...
Medial Longitudinal Arch Deformation During Walking And Stair Navigation While Carrying Loads, 2017 Iowa State University
Medial Longitudinal Arch Deformation During Walking And Stair Navigation While Carrying Loads, Elizabeth Rose Hageman, Michelle Hall, Eric Gerard Sterner, Gary A. Mirka
Gary A. Mirka
Understanding the biomechanics of the medial longitudinal arch (MLA) may provide insights into injury risk and prevention, as well as function of the arch-supporting structures. Our understanding of MLA deformation is currently limited to sit-to-stand, walking, and running.
Material and Methods:
Three-dimensional deformation of the MLA of the right foot was characterized in 17 healthy participants during several simulated activities of daily living. MLA deformation was quantified by both changes in arch length and navicular displacement during the stance phase of three motions: walking, stair ascent, and stair descent. Three levels of load were also evaluated: no load, a ...
The Effect Of Sinusoidal Rolling Ground Motion On Lifting Biomechanics, 2017 Iowa State University
The Effect Of Sinusoidal Rolling Ground Motion On Lifting Biomechanics, Xiaopeng Ning, Gary A. Mirka
Gary A. Mirka
The objective of this study was to quantify the effects of ground surface motion on the biomechanical responses of a person performing a lifting task. A boat motion simulator (BMS) was built to provide a sinusoidal ground motion (simultaneous vertical linear translation and a roll angular displacement) that simulates the deck motion on a small fishing boat. Sixteen participants performed lifting, lowering and static holding tasks under conditions of two levels of mass (5 and 10 kg) and five ground moving conditions. Each ground moving condition was specified by its ground angular displacement and instantaneous vertical acceleration: A): +6°, −0 ...

An Improved Algorithm For Learning To Perform Exception-Tolerant Abduction, 2017 Washington University in St. Louis
An Improved Algorithm For Learning To Perform Exception-Tolerant Abduction, Mengxue Zhang
Engineering and Applied Science Theses & Dissertations
Inference from an observed or hypothesized condition to a plausible cause or explanation for this condition is known as abduction. For many tasks, the acquisition of the necessary knowledge by machine learning has been widely found to be highly effective. However, the semantics of learned knowledge are weaker than the usual classical semantics, and this necessitates new formulations of many tasks. We focus on a recently introduced formulation of the abductive inference task that is thus adapted to the semantics of machine learning. A key problem is that we cannot expect that our causes or explanations will be perfect ...
