Conventional soil maps represent a valuable source of information about soil
characteristics, however they are subjective, very expensive, and time-consuming to
prepare. Also, they do not include explicit information about the conceptual mental
model used in developing them nor information about their accuracy, in addition to the
error associated with...
La pêche côtière au Maroc a connu un essor remarquable ces dernières décennies, poussant là où les ports se créent et se développent sur la côte atlantique. D'abord concentrée a proximité du port de SAF où les débarquements ne dépassaient pas 60.000 tonnes dans les années quarante, l'activité de la...
With all of the efforts that have been conducted over the past 100 years since the first accident causation theory was published, the Accident Proneness theory by Vernon (1918), the construction still trails among different industries in terms of fatal and nonfatal work injuries. Theories and models that have been...
While safety improvements have been made in the construction industry, construction still experiences one of the highest numbers of fatalities annually compared to other industries in the United States with over 970 fatalities in 2016 alone. This number of fatalities drives researchers and safety managers to improve safety measures and...
Minimal research has focused on the social dimension of sustainability in the built environment especially as it relates to the construction workforce. As a result, there are few to no tools available to industry stakeholders to holistically assess and improve the social sustainability of the construction workforce. Given the high...
In the field of construction safety, many researchers have worked to create assessment tools. These tools focus on different aspects of construction safety, such as assessing safety climate, safety culture, etc. Although research indicates that the majority of incidents are caused by unsafe behaviors and acts, there are no comprehensive...
Soil properties may hold the key to improved predictions of soils during digital soil mapping (DSM), which has developed with a focus on environmental factors external to soil. The spatial variability in soil properties was modeled across Malheur National Forest in eastern Oregon as an approach to improve DSM. The...
In some practical systems, most of the errors are of 1 → 0 type and 0 → 1
errors occur very rarely. In this thesis, first, the capacity of the asymmetric
channel is derived. The capacity of the binary symmetric channel (BSC) and the
Z-channel can be derived from this...
Liquefaction of saturated granular material due to cyclic loading can result in catastrophic damage to the built environment. The mechanics of liquefaction have been previously studied through field testing, physical modeling, laboratory experiments, and numerical simulations. However, significant questions remain with respect to the particle-scale behavior of granular materials during...
Despite recent efforts to improve site safety, construction still accounts for a disproportionate injury and illness rate. According to the 2007 injury and illness data released by the National Safety Council, the construction industry has a fatality and disabling injury rate that is approximately three times higher than the all-industry...
