Using Poisson's Equation to Characterize Brain Tumor Shape
The role that tumor shape plays in disease treatment, progression, and outcome is not well understood. This work investigates the quantification of shape information required for the statistical analysis of tumors. The statistical shape characterization method proposed by Haidar et al. 2006 that …

NDT to characterize 3D printed concrete interlayer bonds
… render traditional inspection methods to characterize material quality useless. This research examines nondestructive testing (NDT) techniques that characterize the interlayer bond quality (bond strength) of 3D printed concrete in situ. An experimental study applied four NDT methods (x-ray …

Instrumentation to characterize needle insertion into biological tissue
… human skin using micro needles. It is crucial to characterize the insertion of micro needles into biological tissues. Hence, instrumentation will be designed and fabricated for the characterization of micro needle insertion. This thesis focuses on the design and fabrication of such …

Hydrogeological engineering approaches to investigate and characterize heterogeneous aquifers
This dissertation presents a compilation of five stand-alone manuscripts (Chapters 2 through 5 and Appendix A). Chapters 2 through 5 present hydrogeological analysis approaches, while Appendix A is utilized within the dissertation introduction as an example of a non-physically based modeling …

How Engineering Innovators Characterize Engineering Innovativeness: A Qualitative Study
<p>The use of science and engineering skills to address the problems of modern society is regarded as an economic strategy in developed countries across the world. However, business and political leaders in the United States feel that we, as a society, do not understand that new global competition …

Modeling approaches to characterize the disposition of monoclonal antibodies
… PBPK model to account for a target, relevant to characterize the non-linear clearance due to mAb-target interaction. With model reduction techniques, we reduce the dimensionality of the simplified PBPK model to design 2-compartment models, thus guiding classical model development with …

Characterize the molecular dynamics of materials for 4D printing
4D printing is a nascent field that is foundational for fabrication of complex 3D objects with programmable, temporal attributes that undergo exceptional configuration changes of the 3D structure. While gel-based composite inks are at the crux, the lack of a foundational, materials chemistry …

Patterns of Overeating that Characterize Addictive Tendencies towards Palatable Foods
Previous work focusing on the notion of food addiction has shown that in abundant amounts, highly-caloric- and hyper-palatable-foods can lead to addictive tendencies akin to drugs of abuse such as alcohol, nicotine, cocaine, opioids, and methamphetamine. However, such research is still in its …

Probing early human embryonic development to characterize BMP signaling stimulators
Bone morphogenetic proteins (BMPs) sind sowohl in der Embryonalentwicklung als auch im adulten Organismus von entscheidender Bedeutung. Da ein fehlregulierter Signalweg mit zahlreichen chronischen und schwerwiegenden Krankheiten assoziiert ist, stellt dessen Modulierung einen vielversprechenden …

Pharmacometrics to characterize pharmacokinetics and optimize treatment in understudied populations
… limited data from understudied populations to characterize pharmacokinetics, evaluate existing practices and guide the consideration of alternative dosing scenarios

Use of gene expression to characterize heterogeneous liver cell populations
… limited by their inability to systematically characterize the addition of non-parenchymal cells. In this dissertation, I use gene expression levels quantified by real-time RT-PCR to determine tissue composition. The identified genes demonstrate significant cell-type specificity, magnitude, and …

Development of laboratory class experiment to characterize magneto-rheological fluid
An experimental apparatus has been developed that characterizes magneto-rheological (MR) fluid for an MIT Mechanical Engineering laboratory class by charting the fluid's yield stress versus magnetic field strength. The apparatus consists of a cantilevered beam that is damped using MR fluid, through …

Femtosecond CARS Microscopy to characterize lipid droplets in Engineered Adipose Tissue
Adipose tissue is a type of connective tissue whose purpose was once thought to be limited to fat storage but is now understood to be a key factor in the pathogenesis of different metabolic diseases, including obesity and type-II diabetes. Adipose tissue consists largely of adipocytes, cells …

Engineering Tools to Promote and Characterize Wnt-Mediated Stem Cell Differentiation
… component β-catenin are regulated. To better characterize the downstream effects of Wnt signaling during the manufacturing of therapeutic cells, we also generated CRISPR/Cas9 edited reporter iPSC lines which are designed to detect the expression of Wnt-regulated marker genes with high …

Using natural language processing to characterize the phenomenology of déjà vu
… non-déjà vu reports and found that déjà vu was characterized by increased filler words and recollective confabulation (i.e. recollection of incorrect episodic details). In line with prior work, trials where participants reported déjà vu were more positive, but that was not an important feature …

Using waterflood performance to characterize flow-units in a heterogeneous reservoir
Simulation of waterflood performance is used to verify the characterization of flow-units in a heterogeneous reservoir. BOAST98 software was used for simulation of waterflood performance. Two adjacent five spot patterns in the Stringtown field in West Virginia were selected to be evaluated in this …
