Effective Thermal Management Of Electronic Devices From System To Die Level, Saket Karajgikar Jan 2010

Effective Thermal Management Of Electronic Devices From System To Die Level, Saket Karajgikar

Mechanical and Aerospace Engineering Dissertations - Archive

In any electronic device, the resistance to the flow of current through the transistors, interconnects, etc. results in a significant heat generation. If this heat is not removed from the device by providing appropriate cooling solutions, the possibility of thermal run away is very high. Under this condition the temperature would continue to rise until it reaches a point at which the device ceases to operate or loses its physical integrity. In presence of a cooling mechanism, the temperature rise is moderated as it asymptotically reaches an acceptable steady state value. Before any device is introduced in the market, it …

Formation Of Au Nanoparticles Through Reaction Of Na₃Au(So₃)₂ By Electrochemically Evolved Hydrogen, Yi Jiun Li Jan 2010

Formation Of Au Nanoparticles Through Reaction Of Na₃Au(So₃)₂ By Electrochemically Evolved Hydrogen, Yi Jiun Li

Material Science and Engineering Theses - Archive

Hydrogen evolution during electrochemical deposition has long been regarded as undesired and deliberately suppressed since small hydrogen bubbles could cause a rough surface of deposits. Here, we demonstrate a new role for electrochemically evolved hydrogen, serving as both templates and reducing agents for synthesizing Au nanoparticles via electroless depositions from Na₃Au(SO₃)₂ electrolytes. A series of experiments have been designed to investigate this new role. A working electrode of patterned Ag strips on the non-conductive substrates has been used. It has been observed that when a potential more negative than hydrogen evolution potential was applied to metal areas, a large amount …

Understanding Social Networks In Frazier Courts Hope Vi Development, Christopher Buentello Jan 2010

Understanding Social Networks In Frazier Courts Hope Vi Development, Christopher Buentello

Planning Theses - Archive

The HOPE VI program enacted in 1992 represented a shift in public housing by addressing resident's needs through physical design improvements, self-sufficiency programs, and the deconcentration of poverty. Funding through HOPE VI allowed local housing authorities to demolish deteriorated public housing units and replace them with new income-inclusive housing units. The "hope" would be that low income residents would interact with middle income residents to access resources that are normally beyond the reach of low income individuals. This assumes of course that residents will interact amongst each other. Therefore, I conducted a survey of residents at Dallas' Frazier Courts to …

Examining Individual Student Success Through The Lens Of New Institutional Economics In An Urban Public School District : The Great Graduation Gamble, Arvell Lynn Dehart

Public Affairs Dissertations - Archive

In a perfect world, neo-classical economics and rational theory make sense. But in this imperfect world this paper has turned to Oliver Williamson and his understanding of New Institutional Economics to help us make sense. NIE helps explain institutions and organizations and their role in creating and shaping contracts that fit a very diverse institutional, organizational and human landscape. NIE provides a new lens to examine institutions as diverse as politics and as rigid as economics. Yet, one critical institution has yet to be examined through that lens. That institution is Public Education. It is that examination which this paper …

The Effects Of Behavioral, Geometric And Heavy Vehicle Traffic Flow Characteristics On Capacity And Emissions At Roundabouts, Cho Honest Sone Jan 2010

The Effects Of Behavioral, Geometric And Heavy Vehicle Traffic Flow Characteristics On Capacity And Emissions At Roundabouts, Cho Honest Sone

Civil Engineering Theses - Archive

Modern roundabouts, first constructed in England in the early 1960s, are becoming increasingly popular replacements for signalized and stop controlled intersections in the United States. Roundabouts were introduced to replace traditional traffic circles and rotaries. With the characteristics of entering traffic that yield to circulating traffic and geometric constraints that slow entering vehicles, roundabouts have proven to be more efficient than traffic circles and in some cases than signalized and stop-controlled intersections. Roundabouts often require drivers to decelerate from, and reaccelerate to, highway speeds, and can involve one or multiple stops. One concern about congested roundabouts is that vehicle emissions …

Magnetic Resonance Spectroscopy Study Of Metabolic Profiles In Brain Tumors, Aditya Manoj Patel Jan 2010

Magnetic Resonance Spectroscopy Study Of Metabolic Profiles In Brain Tumors, Aditya Manoj Patel

Bioengineering Theses - Archive

Metabolic profiles in brain tumors were measured using proton (1H) magnetic resonance spectroscopy (MRS) at 3T. Spectra were obtained from normal tissues and tumor mass regions of 6 low-grade gliomas, 7 anaplastic astrocytomas and 23 glioblastoma (GBM) patients, using PRESS at two echo times (TE = 54 and 112 ms). Glutamate (Glu), glutamine (Gln) and lactate (Lac) were well resolved at TE = 112 ms. The ratio of Gln and Glu concentrations, [Gln]/[Glu], was elevated significantly (p < 0.05) in all the tumor types compared to normal tissue. Elevation of Gln was confirmed through [Gln]/[water]; the ratio was increased in all the three tumor types but the increase was significant only in GBM. Glycine (Gly) was increased significantly in GBM. Alanine was detectable from GBM only, indicating its elevation for most malignant tumor. Other observations included significant increases in choline (Cho) and Lac (p < 0.05) and decrease in NAA (N-acetylaspartate), in consistent with prior studies. The creatine to water ratio was observed to decrease in tumor patients but was not significant. Myo-inositol (mIns) was observed to decrease in low grade patients as compared to normal tissue, but was seen to increase with grade of tumor, but was not significant. [Lac]/[water] was significantly higher and [Cho]/[Lac] significantly lower for GBM patients indicating the increase in Lac as compared to normal tissue.Treatment had a significant impact on tumor cells. After radiation therapy the Lac was observed to be elevated significantly and decrease after bevacizumab treatment. [Cho]/[Cr], [Cho]/[NAA], [Gln]/[Glu] and [Cho]/[Gly] was reduced significantly after the bevacizumab treatment. Gly was not detectable after Bevacizumab treatment. Some of the patients showed no infiltrating tumor cells after successful surgery and therapy with ratios close to that of normal tissue. These observations can help in characterizing the effect of various therapies on brain metabolites and tumor cells.

Targeted Delivery Of Carbon Nanotubes To Cancer Cells, Pavitra Chakravarty Jan 2010

Targeted Delivery Of Carbon Nanotubes To Cancer Cells, Pavitra Chakravarty

Bioengineering Dissertations - Archive

CD22 is broadly expressed on human B cell lymphomas. Monoclonal anti-CD22 antibodies (MAbs) alone, or coupled to toxins, have been used to selectively target these tumors both in severe combined immunodeficient (SCID) mice with xenografted human lymphomas and in patients. Single-walled carbon nanotubes (CNTs) attached to antibodies or peptides represent another approach to targeting cancer cells. CNTs convert absorbed near-infrared (NIR) light into heat, which can thermally ablate cells in the vicinity of the CNTs. We have made MAb-CNT constructs where the MAb was either noncovalently or covalently coupled to CNTs, and investigated their ability to bind specifically to cells …

Enhanced Endothelialization On Surface Modified Poly(L-Lactic Acid), Hao Xu

Bioengineering Dissertations - Archive

Current synthetic vascular grafts and polymer-coated drug-eluting stents (DES) have certain limitations, such as thrombosis and restenosis due to the incomplete recovery of vascular endothelial cells on their luminal sides. Surface modification of these materials is a viable method to enhance the endothelialization on them. In this study, we proposed several way to modify poly(L-lactic acid) (PLLA), a promising material for vascular prostheses to enhance the endothelialization on its surface. In the first method, we modified the material surface with deposition of poly(vinylacetic acid) (PVAA) using plasma polymerization. PVAA having different surface densities of -COOH group or film thickness were …

Wide Field Of View Imaging Of Premotor And Sensorimotor Cortex Activation Patterns By Functional Near Infrared Spectroscopy, Pankaj Chand Jan 2010

Wide Field Of View Imaging Of Premotor And Sensorimotor Cortex Activation Patterns By Functional Near Infrared Spectroscopy, Pankaj Chand

Bioengineering Theses - Archive

Functional near infrared spectroscopy (fNIRS) is a non-invasive optical technique which can measure concentration changes of oxygenated (HbO), deoxygenated (HbR), and total hemoglobin (HbT) in brain tissue that are induced by neuronal activation. A major hindrance at present for brain optical imaging research is the limited field of view (FOV) size, which is restricted due to the limited number of source-detector pairs that current fNIRS hardware technology and cost considerations allow. As a result it is challenging to simultaneously capture hemodynamic changes in the premotor, motor and sensory cortex as some of these activations can occur outside the available FOV. …

Novel Animal Model And In Vivo Imaging System To Study Inflammatory Response-Mediated Cancer Metastasis, Cheng-Yu Ko Jan 2010

Novel Animal Model And In Vivo Imaging System To Study Inflammatory Response-Mediated Cancer Metastasis, Cheng-Yu Ko

Bioengineering Dissertations - Archive

Cancer metastasis is the leading cause of death in cancer patients. A vast majority of cancer-related mortality is attributed to this rather than the primary tumor itself, making the understanding of cancer metastasis critically important. Inflammatory responses have been implicated to play an important role in cancer metastasis. However, the investigation of the relationship between inflammation and cancer cell migration is limited by the lack of a reproducible cancer metastasis animal model. To fill the gap, we have recently developed an animal model. This model is composed of a two-step procedure. First, poly-L lactic acid (PLA) microspheres were implanted subcutaneously …
