In recent years, megacity Dhaka is known to have one of the fastest urban population growths in Bangladesh. The population in Dhaka and other megacities has increased from 7 to 50 million during the last four decades. The rapid rate of urban population growth, along with the extreme paucity of real-estate for new infrastructure development or upgrading existing facilities, is already exacerbating the situation for the city planners and exerting tremendous pressure to come-up with viable solutions. Although practice of engineering geology, geotechnical exploration, and testing exists in Bangladesh; the system has still yet to adopt controlled quality standards with ...


Study Of Rheology And Flow Behavior Of Magneto-Rheological Fluids Under The Influence Of A Magnetic Field And Its Potential Applications For Drilling And Completion Operations, John Edwin Estrada Giraldo 2018 Louisiana State University and Agricultural and Mechanical College

Study Of Rheology And Flow Behavior Of Magneto-Rheological Fluids Under The Influence Of A Magnetic Field And Its Potential Applications For Drilling And Completion Operations, John Edwin Estrada Giraldo

LSU Master's Theses

The use of magnetorheological fluids (MRF) is presented as an alternative to overcome some of the problems encountered in the drilling and completion of a well. The magnetorheological fluids can modify their rheological properties instantaneously under the influence of a magnetic field. In this thesis, MRF consist of a base fluid, magnetizable particles and a polymer that supports the particles. The magnetizable particles align in the direction of the magnetic field, thus modifying the rheology of the mixture. Because of this characteristic, the use of this fluid can have advantages in controlling fluid losses while drilling in narrow operating windows ...

Maximizing Financial Benefit Of Lean Six Sigma Projects Through Optimized Selection Criteria, Colin Wasiloff

Engineering Management, Information, and Systems Research Theses and Dissertations

As evolving threats across the globe keep pace with increasing budget constraints, the US Army’s major subordinate commands and their sub-organizations are constantly challenged to do more with less. Resources such as human capital, information technology, facilities, and budgeted funding are stretched as thin as ever, while requirements to serve the Warfighter remain paramount. Each dollar of financial benefit gained through cost reduction efforts at the US Army can affect the Warfighter directly. Budgeted money saved or avoided is reprogrammed both locally and atop the hierarchy at the Department of Treasury to serve the Warfighter better.

Development Of A Uav-Based System To Monitor Air Quality Over An Oil Field, Siwen Liu 2018 Montana Tech

Development Of A Uav-Based System To Monitor Air Quality Over An Oil Field, Siwen Liu

Graduate Theses & Non-Theses

The growth of hydraulic fracturing has pushed the whole petroleum industries forward. As a result, gas (mainly methane [CH4]) emissions have significantly increased over the past decades (Macey et al., 2014). Gas leaks can occur at almost all stages of a petroleum production process, such as drilling, fracking, and refining. For years, ground-based air quality monitoring has been conducted around production sites. An improved understanding of air quality would be enabled by supplementing ground-based with airborne monitoring. The latter would involve the use of unmanned aerial vehicles (UAVs) to carry a compact, portable air monitoring system. The purpose of this ...


Application Of Computational Mbd For Simulation Of Wrap Packaging Performance, Niels Hojen Ostergaard, Stephane Danjou 2018 Rhine-Waal University of Applied Sciences

Application Of Computational Mbd For Simulation Of Wrap Packaging Performance, Niels Hojen Ostergaard, Stephane Danjou

Journal of Applied Packaging Research

This paper concerns evaluation of the performance of plastic wrap films applied for packaging engineering by numerical simulation. In particular, the feasibility of computational techniques as supporting tool for packaging testing is investigated. A wrap film model constituted by a web of point masses connected by springs and dampers is applied to a number of stacked box-shaped objects. These will be modeled as perfectly rigid using simulation techniques from 3D multibody dynamics. Contact mechanics are simulated by penalization methods. A simple example demonstrates the potential of the developed framework.


Post-Wrapping Behavior Of High-Performance Stretch Film, Jake Wyns, John Cook, Kyle Dunno 2018 Atlantic Packaging

Post-Wrapping Behavior Of High-Performance Stretch Film, Jake Wyns, John Cook, Kyle Dunno

Journal of Applied Packaging Research

Compressive force is the energy a stretch film exerts onto the corners of a unit load of product, this paper analyzes the effects of compressive force overtime after application to a unit load. Previous research has shown how storage conditions, pallet configurations, and storage duration affect the performance of various packaging materials, however, there is a lack of this type of study relating to stretch film and load unitization. This paper looks at trends in compressive force depending on whether a film is applied with negative or positive secondary stretch. When a load is stretch wrapped with negative secondary stretch ...

Articles

The problems presented by counterfeit products and documentation are discussed. Limitations of existing holograms for anti-counterfeit applications are described. We describe the advantages of full holographic serialisation and the requirements in terms of materials and techniques for mass production of true serialised holograms. These requirements having been met, we report for the first time the mass production of fully serialised holograms. The novelty of approach consists of the direct use of product manufacturer’s information as the object in a holographic recording system along with a self-processing photopolymer and modular optical system to facilitate mass production of truly serialised volume ...


Data-Driven Uncertainty Quantification Interpretation With High Density Regions, Matthew Gregor Peterson 2018 University of New Mexico

Data-Driven Uncertainty Quantification Interpretation With High Density Regions, Matthew Gregor Peterson

Computer Science ETDs

In a time when data is being constantly generated by phones, vehicles, sensor net- works, social media, etc. detecting anomalies with in the data can be very crucial. In cases where we know little prior knowledge about the data, it becomes difficult to extract uncertainty about our results. In this thesis, we will propose a framework in which we can extract uncertainty distributions from data-driven modeling prob- lems. We will show some concrete examples of how to apply framework and provide some insight into what the uncertainty distributions are telling us using High Density Regions (HDRs).

Demonstration Of The Gas Assisted Gravity Drainage (Gagd) Process In Carbonate Rocks., Alok Jiteshkumar Shah 2018 Louisiana State University and Agricultural and Mechanical College

Demonstration Of The Gas Assisted Gravity Drainage (Gagd) Process In Carbonate Rocks., Alok Jiteshkumar Shah

LSU Master's Theses

The Gas Assisted Gravity Drainage (GAGD) process was developed and patented by Dr. Rao at LSU in the early 2000s. The process involves the use of several existing or new vertical injection wells to inject gas and use the natural segregation of reservoir fluids from the density difference and the gravitational forces to displace the trapped oil and mobilize the oil downwards to be produced by a horizontal producing well. The GAGD process can be implemented as a secondary or tertiary oil recovery method. Several physical model experiments have been conducted to demonstrate the effectiveness of the GAGD process for ...

Discrimination Against Women In The Field Of Engineering, Julia Weber

Undergraduate Voices

This article focuses on the position of women in the field of engineering, specifically why the field is male-dominated and why this condition should change. When I state the field is male-dominated, I am addressing both the proportion of men in the field in comparison to women and discrimination towards women in the workplace.

Throughout this article, I will be focusing on women in the field of engineering. I will look into why the field is so male-dominated (Chu, 2005; Hunt, 2016; Ramirez & Wotipka, 2001) and how this has begun to change over time (Hill, Corbett, & St Rose, 2010; Morgan, 1992; Ramirez & Wotipka, 2001; Scandura & Ragins, 1993; Torre, 2014). Additionally, I will look into whether or not women within the ...
