Modeling and suppression of latchup
… of external latchup and the standard latchup tests. The term collection efficiency is defined in this chapter to represent the number of injected carriers participating in triggering latchup. Circuit-level models are proposed to understand latchup behavior under various testing conditions. …

A descriptive study of the use of troponin I testing at a Cape Town district hospital
Introduction: Troponin I tests have been shown to be accurate and are relied upon to assist in making critical decisions regarding patient care in patients presenting with chest pain. The tests are expensive, however, and so their rational use becomes extremely important in a budget-constrained …

Environmental effects on the fatigue behavior of copper nickel alloys
Mode I and Mode III fatigue tests were performed on copper nickel alloys in helium, salt water environments. The hydrogen, oxygen, two alloys used air and in this investigation were 90-10 and 70-30 copper nickel. Both alloys contained iron which was added to improve the erosion corrosion …

A comparison of spatial interpretations of NASA's payload operations control center, Marshall Space Flight Center, using real world and virtual reality observations
… using the Wilcoxon Signed Ranks Test, and I tests. Findings revealed few differences among the real and the VR worlds. Changes to the virtual world were generally recognized.

An International Spatial Analysis of the Welfare Spending’s Influence on Measles Immunization
… analytical approach, global and local Moran’s I tests indicate that spatial relationships are present among the variables of interest. Therefore, a conditional autoregressive model is also tested to account for spatial random effects. In the fourth manuscript, these results outline the findings …

Essays on structural changes in high dimensional econometric models
… estimation. This essay also proposes (i) tests for the null of no change versus the alternative of l changes and (ii) tests for the null of l changes versus the alternative of l + 1 changes. These tests allow us to make inference on the presence and number of structural changes. Simulation …
