Proton emission imaging of the nuclear burn in inertial confinement fusion experiments
A proton core imaging system has been developed and extensively used for measuring the nuclear burn regions of inertial confinement fusion implosions. These imaging cameras, mounted to the 60-beam OMEGA laser facility, use the penetrating 14.7-MeV protons produced from the fusion of deuterium and …

Optimal stress screening for products sold under warranty
In the face of increasing awareness among customers and today's competitive market, the warranty of a product has become an added feature in marketing strategy. A reliable product causes less warranty support cost. However, a more reliable product costs more to manufacture. Thus, a suitable …

Optimizing product testing in the electronics manufacturing industry
This thesis provides insight into methods for data analysis of testing procedures to optimize the overall testing times within the electronics manufacturing industry. By analyzing each test regime within the manufacturing sequence individually, with the goal of overall test time reduction, better …

Modeling 0.18[m̳u̳]m BiCMOS (S18) high sheet resistance (RPH) polysilicon resistor lifetime drift
… lifetime test (HALT), is a stress testing methodology for accelerating product reliability that is universally conducted during the engineering development process. In conducting a HALT for circuit components, a burn-in procedure is executed, where the circuit/device is heated to a high …

Choice functions, dynamics, and equal representation
In this thesis, we study dynamics of systems evolving according to choice functions; such scenarios have the potential of being applicable in data and network processing, decision theory, and sampling. In particular, consider n linearly ordered size-one "spots" and k classes from which to fill the …

A Narrative-Focused Machine Learning Approach to Predicting Feature Film Success
… by marketability, and it has relied on gut feelings and subjectivity to produce feature films. The analysis of the relationship between a screenplay’s narrative and a film’s success has been widely overlooked due to the challenges involved in data acquisition and complexity. This study …

Experimental Analysis on Aging of Integrated Circuits
<p>As we enter into sub-nanometer technologies in order to increase performance of CMOS devices, reliability issues such as negative bias temperature instability (NBTI), hot carrier injection (HCI), time dependent dielectric breakdown (TDDB), and electromigration (EM) are coming up as potential …

Death and Value Reignition: Lucky in the Chance to Die
In this thesis I examine life-extension and embodied immortality and ask whether these are intrinsically problematic or undesirable. I examine the history of the concept of immortality and find that the usage of the term has nearly always referred to extended but mortal lifespans. I observe that …

Redefining manufacturing quality control in the electronics industry
The most time consuming and capital intensive portion in the assembly of power electronic devices is the test system. A comprehensive test system including functional and stress screening technologies can significantly increase assembly times and more than double the capital investment required in …

Isothermal model of ICF burn with finite alpha range treatment
A simple model for simulating deuterium tritium burn in inertial confinement fusion capsules is developed. The model, called the Isothermal Rarefaction Model, is zero dimensional (represented as ordinary differential equations) and treats disassembly in the isothermal limit. Two substantive …

Predicting the post-fire responses of two forest tree precursors after an autumn fire in mountain fynbos
This study investigated whether post-fire survival of two fynbos forest precursors Rapanea melanophloeos (L). Mez and Kiggelaria afri.cana L. were dependent on plant size or fire intensity. Two possible mechanisms of size dependent survival were investigated; 1) is fire survival the (ability to …

Study of space-time evolution of flux in a long-life traveling wave reactor
Simulations using MCNPX have been carried out to analyze the space and time evolution of flux in a Traveling Wave Reactor under constant thermal power condition. For the analyses of flux shape, a 3-D box-shaped model of the reactor is developed. The reactor core is divided into two primary regions: …

Spatial distribution of charcoal after a prescribed fire on Middle Mountain, VA
This study examines the spatial distribution of surface charcoal after a managed fire and its relationship to fire intensity and site characteristics. Such studies are lacking for the southern Appalachian Mountains. In April 2010, The Nature Conservancy conducted a ~150ha prescribed burn in pine- …

Synthesis and characterization of metal-based reactive powders
Aluminum added to propellants, explosives, and pyrotechnics, boosts their energy density. Different approaches were investigated that could shorten aluminum ignition delays, increase combustion rates, and decrease the tendency of aluminum droplets to agglomerate. Here, Al-based reactive, …

Scald burn admissions to Princess Margaret Hospital in 1998 and 2008: A comparative analysis
Scald is the most common form of burn in young children, accounting for over 50% of all paediatric burn admissions in Western Australia (WA). Interventions implemented over the past few years focussed on prevention, first aid, and improved services postinjury (Department of Health Western …

Characterization of 1-butanol electrospray combustion
This study examined the characteristics of electrosprays of 1-butanol that burn in air. Still images and high-speed movies captured with a laser sheet present helped to establish general flame phenomenology and features such as shape, size, and stability of the spray flame. The dependence of the …

Fuel burn reduction potential from delayed deceleration approaches
Changing aircraft operational procedures is one strategy that can be used to reduce fuel burn and mitigate environmental impacts of aviation in relatively short timeframes with existing aircraft types. One promising modification comes from increasing the use of Delayed Deceleration Approaches where …
