Understanding the global pattern of glaciation can aid interpretation of what caused late-Pleistocene glacial cycles. Here I investigate the glacial history of the Khumbu Glacier of the Mount Everest region of Nepal. Prominent hypotheses for Himalayan glaciation suggest importan…

Predecir el precio del cobre no es una tarea fácil. Productores, consumidores, inversionistas e incluso algunos gobiernos deben enfrentarse a este tema. Existen muchas fuentes de información y diferentes modelos para completarla, sin embargo, no hay un consenso claro de cuándo e…
In education contexts, agent-based simulations have been used at all levels, from the individual to the classroom to the state, to explore individual-level interactions and often to provide conclusions and explanations that could support decision-making. The aim of this research…
The Ganges-Brahmaputra-Meghna (GBM) river basins exhibit extremes in surface water availability at seasonal to annual timescales. However, due to lack of near basin-wide hydrological data, whether it is real-time or historical, water management at the basin-wide scale has been q…
Although the main limitation of crop production in the arid and semiarid regions of Morocco is lack of sufficient rainfall, phosphorus (P) nutrient deficiencies also are major obstacle to maximum crop production. Fertilizer management is an important step in sustainability of cr…
Digital signal processing (DSP) systems operating on analog inputs are often limited by the speed of the analog-to-digital (A/D) interface. With a given process, the maximum sample rate at which a given analog-to-digital converter (ADC) will operate is limited for a given resolu…
After undergoing a study about current engine modelling and mapping approaches as well as the engine modelling requirements for different applications, a major problem found to be present is the extensive and time consuming mapping procedure that every engine has to go through s…
The International Temperature Scale of 1990 (ITS-90) defines the present S.I.(“System International”) means of measuring temperature. The ITS-90 uses the freezing points of metals to define temperature fixed points. It also uses long-stemplatinum resistance thermometers to inter…
A constitutive model is a relationship between material stimuli and responses. Calibration of model parameters within well-defined constitutive models is thus key to the generation of accurate model-based predictions. One limitation of traditional material calibration is that on…
Historically, decision-makers have used expert opinion to supplement lack of data. Expert opinion, however, is applied with much caution. This is because judgment is subjective and contains estimation error with some degree of uncertainty. The purpose of this study is to quantif…
Dynamically Coupled Socioeconomic system dynamics models integrated with physically-based Environmental Models (DCSEM) can aid in resolving complex environmental problems involving dynamic interactions between socioeconomic and biophysical systems. DCSEMs are promising tools for…
Improvement in analytical methods, including extraction procedures has been a recurrent topic in mycotoxin research due to the fact that mycotoxins are ubiquitous, potent and notoriously difficult to eradicate from the food and feed supply chain. Effective management of these to…
The desire to unveil the mystery of dark matter which, according to compelling astrophysical and cosmological evidence, constitutes about 85% of the matter in the Universe, drives physicists to continuously develop their tools and search methodologies. There are several proposed…
Pseudo-Invariant Calibration Sites (PICS) are one of the most popular methods for in-flight vicarious radiometric calibration of Earth remote sensing satellites. The fundamental question of PICS temporal stability has not been adequately addressed. However, the main purpose of t…
Basin and Petroleum System Modeling (BPSM) is coupled-physics approach that tracks over the course of basin history, the evolution of basin geometry, compaction, pressure, fluid flow, temperature, and chemical transformation of organic matter to quantitatively predict petroleum …
A highly selective and rapid optical sensing approach was previously demonstrated as a potential non-invasive medical diagnostic method for real-time detection of acetone as a biomarker in human breath to determine the blood glucose level of the patients. The approach employed a…
This work concerns the planimetric evolution of free meandering rivers, whose associated riverbank erosion and channel changes notoriously pose a hazard to infrastructure within their vicinity as well as affect the health of the river ecosystem. It aims to address two research n…
This dissertation studies a special feature about the international financial market. Classical theories often assume that countries are symmetric, but realistically the international financial market is heavily US dollar dominated, which stimulates my interest to study whether …
