User Guide For Dust Modeling Using Cmaq 5.3.1 And Wrf 4.2.1, Zachary D. Lawless, Ariel S. Cable, Cameron B. Van Dyke, Bradley R. Adams Jan 2021

User Guide For Dust Modeling Using Cmaq 5.3.1 And Wrf 4.2.1, Zachary D. Lawless, Ariel S. Cable, Cameron B. Van Dyke, Bradley R. Adams

Faculty Publications

Researchers at Brigham Young University (BYU) have developed a software framework for modeling dust emission and transport using the Community Multiscale Air Quality (CMAQ) modeling system in conjunction with the Weather Research and Forecasting (WRF) model and other utility programs. This framework uses meteorological data, land use data, and soil properties to predict dust concentrations for a specified area. This User Guide describes the start-to-finish process required to install and utilize relevant software to calculate and visualize dust concentrations. Note that the examples and figures provided in the guide are specific to Utah in the western United States, where this …


Non-Equilibrium Behavior Of Large-Scale Axial Vortex Cores, Robert L. Ash, Irfan R. Zardadkhan Jan 2021

Non-Equilibrium Behavior Of Large-Scale Axial Vortex Cores, Robert L. Ash, Irfan R. Zardadkhan

Mechanical & Aerospace Engineering Faculty Publications

A logical basis for incorporating pressure non-equilibrium and turbulent eddy viscosity in an incompressible vortex model is presented. The infrasonic acoustic source implied in our earlier work has been examined. Finally, this non-equilibrium turbulent vortex core is shown to dissipate mechanical energy more slowly than a Burgers vortex, helping us to explain the persistence of axial vortices in nature. Recent molecular dynamics simulations replicate aspects of this non-equilibrium pressure behavior.


Évaluation Des Méthodes D’Essai Pour Déterminer La Résistance Au Glissement Des Chaussures Sur Des Surfaces Glacées : Document Synthèse, Chantal Gauvin, Atena Roshan Fekr, Yue Li, Gordon Wong, Wayne Cheng, David Pearsall, Tilak Dutta Jan 2021

Rapports de recherche scientifique

En saison hivernale, glisser sur la glace est l’un des principaux risques inhérents aux activités professionnelles exercées à l’extérieur. Alors que de nombreux travailleurs comptent sur leurs chaussures de travail pour les empêcher de glisser, ces derniers se retrouvent souvent devant un choix difficile quand vient le temps de sélectionner les meilleures bottes antidérapantes pour l’hiver. Des méthodes d’essai normalisées existent déjà pour évaluer le coefficient de friction (CdF) des chaussures sur des surfaces autres que la glace. Bien que l’appareil utilisé pour ces tests puisse être utilisé en tandem avec une machine qui permet de fabriquer des surfaces glacées …


Evaluation Of Test Methods For Determining Footwear Slip Resistance On Ice Surfaces, Chantal Gauvin, Atena Roshan Fekr, Yue Li, Gordon Wong, Wayne Cheng, David Pearsall, Tilak Dutta Jan 2021

Evaluation Of Test Methods For Determining Footwear Slip Resistance On Ice Surfaces, Chantal Gauvin, Atena Roshan Fekr, Yue Li, Gordon Wong, Wayne Cheng, David Pearsall, Tilak Dutta

Rapports de recherche scientifique

Slipping on ice is one of the main risks of outdoor occupational activities during winter. Ice and freezing rain were involved in 14% of slip, trip and fall (STF) accidents from 2014 to 2016 in Quebec. Many workers who perform outdoor activities rely on their boots to prevent them from slipping. However, choosing the best slip resistant footwear is challenging. Currently, there is no standard test method for evaluating slip resistance of footwear on ice surfaces. The SATRA STM 603 whole shoe tester is used in standard test methods (ASTM International, 2019b, F2913-19; International Organization for Standardization [ISO], 2019, 13287:2019) …


Mise Au Point D’Une Méthode De Mesure Objective De L’Effet D’Occlusion Basée Sur La Voix, Hugues Nélisse, Hugo Saint-Gaudens, Franck Sgard, Olivier Doutres Jan 2021

Mise Au Point D’Une Méthode De Mesure Objective De L’Effet D’Occlusion Basée Sur La Voix, Hugues Nélisse, Hugo Saint-Gaudens, Franck Sgard, Olivier Doutres

Rapports de recherche scientifique

Lors de l’utilisation de protecteurs auditifs ou de prothèses auditives, le fait d’obstruer le canal auditif peut engendrer un effet indésirable et désagréable, appelé « effet d’occlusion », qui se manifeste notamment par la sensation que notre propre voix sonne différemment, avec de basses fréquences amplifiées, qu’elle est distordue. L’effet d’occlusion est souvent considéré comme une source d’inconfort qui entraîne parfois les utilisateurs de protecteurs ou de prothèses à mal les utiliser ou encore à simplement les retirer. Dans le cas des travailleurs, par exemple, le retrait des protecteurs auditifs peut les exposer à des niveaux de bruits potentiellement dangereux, …


การประยุกต์ใช้แผ่นที่ปรับค่าความแข็งด้วยลมเข้ากับมือจับแบบง่าย, เจตนิพิฐ อรุณรัตน์ Jan 2021

การประยุกต์ใช้แผ่นที่ปรับค่าความแข็งด้วยลมเข้ากับมือจับแบบง่าย, เจตนิพิฐ อรุณรัตน์

Chulalongkorn University Theses and Dissertations (Chula ETD)

จากแนวคิดการใช้งานผิวหนังเทียมหรืออุปกรณ์ห่อหุ้มเพื่อเพิ่มความปลอดภัยและประสิทธิภาพในการทำงานของหุ่นยนต์ นำมาสู่การพัฒนาผิวหนังเทียมที่ติดตั้งบริเวณมือจับของหุ่นยนต์ โดยผิวหนังเทียมเหล่านี้จะมีค่าความแข็งที่แตกต่างกันตามการใช้งาน วิทยานิพนธ์เล่มนี้นำเสนอการออกแบบและขึ้นรูปแผ่นที่ปรับค่าความแข็งได้ (VSPs) ด้วยความดันลม ซึ่งทำหน้าที่เสมือนเป็นผิวหนังเทียมของมือจับ จากนั้นนำแผ่นดังกล่าวไปทดลองใช้กับมือจับแข็งเกร็งอย่างง่าย เพื่อหยิบจับวัตถุซึ่งไม่ทราบตำแหน่ง รูปทรงและความแข็งที่แน่ชัดด้วยวิธีการควบคุมอิมพีแดนซ์ VSPs สร้างขึ้นจากวัสดุอ่อนนุ่มประเภทซิลิโคน ซึ่งขึ้นรูปโดยใช้การหล่อและเสริมความแข็งแรงด้วยเส้นใยไฟเบอร์ มีโครงสร้างภายในเป็นทรงกระบอกเรียงตัวขนานกัน สามารถควบคุมค่าความแข็งผ่านการควบคุมค่าความดันโดยใช้ปั๊มเข็มฉีดยาร่วมกับตัวควบคุมแผนเลื่อน จากการทดลองประยุกต์ใช้ VSPs ร่วมกับมือจับแข็งเกร็งพบว่า VSPs ช่วยเพิ่มความปลอดภัยและความยืดหยุ่นในการทำงาน เนื่องจากสามารถปรับค่าความแข็งให้เหมาะสมกับการทำงานนั้น ๆ ได้ โดยการปรับค่าความแข็งเพิ่มจะช่วยลดระยะเวลาในการทำงาน หากลดค่าความแข็งจะช่วยเพิ่มความปลอดภัยและความเสถียรในการทำงานแทน

A Numerical Study Of Flow Past Arrays Of Cylinders At Low Reynolds Number, Woraphon Wannaviroj Jan 2021

A Numerical Study Of Flow Past Arrays Of Cylinders At Low Reynolds Number, Woraphon Wannaviroj

Chulalongkorn University Theses and Dissertations (Chula ETD)

Coastal erosion along shorelines has increasingly been prevalent. A popular method for alleviating this problem is to use breakwaters, made of bamboo, known as “bamboo fencing”. The thesis numerically investigates steady, low-velocity flow past several geometrical configurations of bamboo fencings, modelled as array of cylinders using the ANSYS®-Fluent software. The Reynolds number based on incoming flow velocity (U∞), cylinder diameter (D), and fluid kinematic viscosity is Re = 100. Validation is done for mesh convergence and time-step size for the two-dimensional flow past a circular cylinder. For a pair of side-by-side arranged cylinders, it is found that the effect of …


A New Line-By-Line Methodology Based On The Spectral Contributions Of The Bands, Felipe R. Coelho, Aline Ziemniczak, Somesh Roy, Francis H.R. França Jan 2021

A New Line-By-Line Methodology Based On The Spectral Contributions Of The Bands, Felipe R. Coelho, Aline Ziemniczak, Somesh Roy, Francis H.R. França

Mechanical Engineering Faculty Research and Publications

This study presents a new methodology to solve thermal radiation in participating gases, the spectrally reduced integration (SRI), which employs a non-uniform spectral discretization to considerably reduce the computational cost of the line-by-line (LBL) solution while still maintaining good levels of accuracy. This non-uniform spectral mesh is generated from discretization schemes based on the spectral contributions of the bands, which apply less or more refined spectral resolution depending on the importance of the bands to the radiative transfer. Based on this methodology, several schemes were initially proposed and evaluated for a homogeneous H2O-CO2 mixture test case. Results …


Human-Robot Collaboration Enabled By Real-Time Vision Tracking, Travis Deegan Jan 2021

Human-Robot Collaboration Enabled By Real-Time Vision Tracking, Travis Deegan

Electronic Theses and Dissertations

The number of robotic systems in the world is growing rapidly. However, most industrial robots are isolated in caged environments for the safety of users. There is an urgent need for human-in-the-loop collaborative robotic systems since robots are very good at performing precise and repetitive tasks but lack the cognitive ability and soft skills of humans. To fill this need, a key challenge is how to enable a robot to interpret its human co-worker’s motion and intention. This research addresses this challenge by developing a collaborative human-robot interface via innovations in computer vision, robotics, and system integration techniques. Specifically, this …
