Effect Of The Physical Environment On Teacher Satisfaction With Indoor Environmental Quality In Early Learning Schools, Stuart Shell

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

While the quantity and quality of teacher-child interactions plays a key role in emotional and cognitive development for children, there is scant evidence regarding the contribution of physical environment to child outcomes. This study seeks to understand better the relative importance of variables within the physical environment for occupants. The research design targets teachers’ satisfaction with the physical environment as the outcome variable, based on the assumption that teachers who are more satisfied with their classroom provide higher-quality interactions with children. Teachers from two early learning schools with a total of 31 classrooms completed a written survey that asked about …

Food For Function, Ryan Desilva

Architecture Senior Theses

This thesis proposes to develop and apply sustainable energy strategies driven by the needs of yet commercial kitchens within the context of adaptive re-use of buildings. Spatializing systems within the framework of building envelopes will minimize energy usage, promote smarter holistic building design; but most importantly, teach culinary students sustainable strategies related to the growth, use and reuse of food as it pertains to the consumption and production of energy.

On Turbulent Mixing In Stably Stratified Wall-Bounded Flows, Farid Karimpour, Subhas Karan Venayagamoorthy

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this paper, we provide an analysis of turbulent mixing in stably stratified wall-bounded flows to highlight a number of important issues such as prediction of the turbulent viscosity, the turbulent diffusivity, and the irreversible flux Richardson number. By invoking the equilibrium assumption between the production rate of the turbulent kinetic energy (P), the dissipation rate of the turbulent kinetic energy (P), and the turbulent potential energy dissipation rate (εPE) as P ≈ ε + εPE and also assuming equilibrium between the buoyancy flux (B) and εPE as -B ≈ εPE, we first propose that the irreversible flux Richardson number …

Consolidation-Induced Solute Transport For Constant Rate Of Strain. Ii: Comparison With Incremental Loading, Patrick J. Fox, Hefu Pu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This paper presents a numerical investigation of one-dimensional large strain consolidation-induced solute transport for incremental loading (IL) and constant rate of strain (CRS) conditions. Solute transport accounts for advection, diffusion, dispersion, linear and nonlinear sorption, and equilibrium and nonequilibrium sorption, and is consistent with temporal and spatial variations of porosity and seepage velocity in the consolidating soil. Simulations were conducted using material properties for kaolinite clay and indicate that IL and CRS conditions produce significantly different responses during the course of consolidation, including applied stress, rate of settlement, excess pore pressure, and local strain. However, for a given set of …

Consolidation-Induced Solute Transport For Constant Rate Of Strain. I: Model Development And Simulation Results, Hefu Pu, Patrick J. Fox

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

A numerical model, called CSTCRS1, is presented for coupled one-dimensional consolidation and solute transport under constant rate of strain (CRS) loading conditions. The consolidation algorithm accounts for vertical strain, general constitutive relationships, relative fluid velocity, changing compressibility and hydraulic conductivity during consolidation, and an external hydraulic gradient. The solute transport algorithm accounts for advection, dispersion, linear and nonlinear sorption, and equilibrium and nonequilibrium sorption. Soil compressibility is rate-independent and as such CSTCRS1 is more appropriate for less-structured soils. The model is based on a dual-Lagrangian framework that separately tracks the motions of sold and fluid phases. The development of CSTCRS1 …

Influence Of Portland Cement And Ground-Granulated Blast-Furnace Slag On Bleeding Of Fresh Mix, Hong Jae Yim, Jae Hong Kim, Seong Ho Han, Hyo Gyoung Kwak

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Bleeding occurs when freshly mixed cement-based materials settle in a form, and this phenomenon influences the quality of the fresh state as well as the hardened state. This paper attempts to measure the bleeding of Portland cement and ground granulated blast furnace slag (GGBFS) paste mixtures. To investigate the influence of water-to-powder ratio and the used powders under high pressure on bleeding, a pressure vessel and various types of freshly mixed paste were prepared. The packing density and permeability were measured and discussed to understand material effects on the bleeding phenomenon.

Development Of Simulation Modules For Liquid Desiccant Systems In Sorpsim, Zhiyao Yang

Open Access Theses

Liquid Desiccant Systems (LDS) have been an attractive alternative to the conventional vapor-compression air conditioning technology in HVAC applications for their thermally-driven nature and the expertise in dealing with large latent load in a more energy-efficient way. Much effort has been made during the past decades to study the performance of LDS and their components both experimentally and through modelling approach. However, predicting the performance of LDS is still a skill-demanding task because it involves model implementation, retrieval of fluid properties, solving procedure setup, and preparation of a good set of initial guess value to model just one component. It …

Modeling Person-To-Person Contaminant Transport In Enclosed Environments, Chun Chen

Open Access Dissertations

It is essential to predict person-to-person contaminant transport in enclosed environments to improve air distribution design and reduce the infection risk from airborne infectious diseases. This study aims to improve and accelerate the simulation of person-to-person contaminant transport in enclosed environments. ^ This investigation first conducted experimental measurements of person-to-person contaminant transport in an office mockup and the first-class cabin of a functional MD-82 aircraft. The experimental data of steady-state airflow, temperature, and gas contaminant concentration fields obtained in the office were used to validate the steady-state computational fluid dynamics (CFD) models. In the aircraft cabin, the transient particle concentrations …

Aspen Art Museum, Rumiko Handa

Architecture Program: Faculty Scholarly and Creative Activity

'I hope when people come to the New Aspen Art Museum they will sense that this building is very much at home in Aspen and could only live here', Shigeru Ban states in a short essay to visitors included in the museum brochure. Indeed, the way in which Ban's design fits uniquely within its context is nothing less than extraordinary. A full appreciation of his accomplishment, however, requires a study of Aspen's history.

What strategies are available to the architect who intends to design a museum that fits well for a community with keen interests in arts but lacking in …

Failure At Fidenae: Visualization And Analysis Of The Largest Structural Disaster In The Roman World, Rebecca Napolitano

Physics, Astronomy and Geophysics Honors Papers

A digital reconstruction of the amphitheater at Fidenae, which collapsed in 27 A.D., was produced as a result of textual, architectural, archaeological, and engineering analysis. Primary literary sources, such as Tacitus and Suetonius, examined in conjunction with proximal archaeological evidence, allowed for the most probable seating capacity and the scale of the amphitheater to be determined. Architectural evidence of other wooden structures found on Trajan’s Column allowed for a most probable projection of a three dimensional model to be created using AutoCAD. With this most probable model determined, engineering analysis was utilized in order to understand the failure at Fidenae …

Influence Of Collaborative Learning On Women’S Experiences Of Engineering Education, Shannon Chance, Brian Bowe

Other resources

In a study of 55 electrical engineering students, Yadav, et al., found learning gains among students in Project-Based Learning (PBL) to be twice the gains of those taking traditional lecture courses. Du and Kolmos indicate groupbased PBL is more supportive and appealing to women than traditional lecture formats. Savin-Baden posits that female and minority students are more likely to ask questions in non-competitive PBL environments. This study interrogates the claim that PBL is particularly supportive to female and minority students. This work-in-progress uses a phenomenological research methodology to investigate how collaborative learning (in formal as well as non-formal settings) influences …

Evaluation Of An Improved Technique For Geosynthetic-Reinforced And Pile-Supported Embankment, Jun Zhang, Shao Wen Liu, He Fu Pu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

With a large number of applications of conventional technique for geosynthetic-reinforced and pile-supported (GRPS) embankment (called CT embankment), many deficiencies have been exposed. In view of the deficiencies, an improved technique, fixed-geosynthetic-reinforced and pile-supported embankment (called FGT embankment), is developed. To investigate the performance of the FGT embankment, the comparison analyses and parametric studies are conducted by Finite Element Method (FEM). The influencing factors investigated include elastic modulus of soil, tensile stiffness of geosynthetics, pile length, pile spacing, and pile elastic modulus. In addition, the cost evaluation for the FGT embankment and CT embankment is also made. The results show …
