Recycling Made Easy: An Ergonomic Approach To Home Recycling And Trash Containers, Landon P. Boisclair 2010 California Polytechnic State University - San Luis Obispo

Recycling Made Easy: An Ergonomic Approach To Home Recycling And Trash Containers, Landon P. Boisclair

Industrial and Manufacturing Engineering

The purpose of this project is to create an ergonomically sound recycling/trash container, with the ultimate hope of making the recycling process easier and more intuitive, thereby increasing recycling rates. Currently, while there are many recycling/trash containers available for purchase, there is no product that has a design without glaring ergonomic flaws. An ergonomic design and product prototype was created as a part of this project, and was subsequently tested against a conventional prototype model. The data collected from the experiments conducted suggests that the new ergonomic model makes the waste disposal process and the container transportation process ...


Evaluation Of An Eye Tracking Device To Increase Error Recovery By Nursing Students Using Human Patient Simulation, Yan Shen 2010 University of Massachusetts Amherst

Evaluation Of An Eye Tracking Device To Increase Error Recovery By Nursing Students Using Human Patient Simulation, Yan Shen

Masters Theses 1911 - February 2014

This study evaluates the application of an eye tracking device in nursing education. An experiment is designed to test the effectiveness of the eye tracking device used as a tool for providing instructional feedback in error identification and recovery by nursing students undertaking tasks in a simulated clinical setting. This experiment is performed on three groups of nursing students. In the first phase, all groups are tested in a simulated clinical scenario and their eye movements are recorded using an eye tracking device. In the second phase, the evaluation only group (control group) gets instructors’ feedback regarding their performance without ...


The Effects Of Horizontal Load Speed And Lifting Frequency On Lifting Technique And Biomechanics, Boyi Dai, Sangeun Jin, Xiaopeng Ning, Gary Mirka 2010 Iowa State University

The Effects Of Horizontal Load Speed And Lifting Frequency On Lifting Technique And Biomechanics, Boyi Dai, Sangeun Jin, Xiaopeng Ning, Gary Mirka

Industrial and Manufacturing Systems Engineering Publications

Lifting loads that have a horizontal velocity (e.g. lifting from a conveyor) is often seen in industry and it was hypothesised that the inertial characteristics of these loads may influence lifting technique and low back stress. Seventeen male participants were asked to perform lifting tasks under conditions of four horizontal load speeds (0 m/s, 0.7 m/s, 1.3 m/s and 2.4 m/s) and two lifting frequencies (10 and 20 lifts/min) while trunk motions and trunk muscle activation levels were monitored. Results revealed that increasing horizontal load speed from 0 m/s to ...


An Empirical Validation Of A Base-Excitation Model To Predict Harvestable Energy From A Suspended-Load Backpack System, Xu Xu, Simon M. Hsiang, Gary Mirka 2010 Harvard University

An Empirical Validation Of A Base-Excitation Model To Predict Harvestable Energy From A Suspended-Load Backpack System, Xu Xu, Simon M. Hsiang, Gary Mirka

Industrial and Manufacturing Systems Engineering Publications

Suspended-load backpacks have been proposed as a way to provide power for small electronic devices by capturing the mechanical energy generated by the vertical movement of the suspended load and converting it into electrical energy. The aim of the current study was to build a base excitation model able to predict the relative velocity of the load (an index of the amount of harvestable energy of such a system) using as inputs the mass of the suspended load, the walking speed and the leg length of the user. Nine human participants walked on a treadmill under two load conditions (15 ...


The Context Matters: Maritime Safety In The Vessel Traffic Service (Vts) Domain, Gesa Praetorius, Margareta Lützhöft, Karl Bruno 2009 Selected Works

The Context Matters: Maritime Safety In The Vessel Traffic Service (Vts) Domain, Gesa Praetorius, Margareta Lützhöft, Karl Bruno

Gesa Praetorius

Vessel Traffic Service (VTS) is a service to the maritime community implemented to promote and improve maritime safety. In recent years VTS has become a topic of increased interest for maritime stakeholders and the general public. To derive insights on how maritime safety is constructed in the VTS domain this exploratory study was conducted. Four VTS centres were visited and 15 VTS operators were interviewed and observed at work. Further a focus group interview with 8 VTS operators with focus on decision support tools in the VTS domain was conducted. The results of the study indicate that VTS operators define ...


Enacting Reliability: First Steps To Define Safety In The Vts Domain, Gesa Praetorius, Karl Bruno, Margareta Lützhöft 2009 Selected Works

Enacting Reliability: First Steps To Define Safety In The Vts Domain, Gesa Praetorius, Karl Bruno, Margareta Lützhöft

Gesa Praetorius

Although the term maritime safety is widely used in the maritime industry, there is no exact definition of what it entails. An explorative study of the VTS domain has been conducted to approach the concept of maritime safety. Four VTS centres were visited and 16 VTS operators were interviewed and observed to derive insights in how maritime safety is constructed from the perspective of an operator. Further, definitions of maritime safety by central actors in the maritime domain have been investigated through a literature study and several interviews. The results indicate that there is no common definition of the term ...
