Artificial Recharge Of Groundwater As A Management Tool For The Kabul Basin, Afghanistan, Mohammad Farid Masoom

LSU Master's Theses

Decades of war and political instability, consecutive droughts, population increase and displacement, caused serious infrastructural damages to water resources of Afghanistan. The main source of water supply for people in Afghanistan is groundwater. However, over-exploitation of groundwater has led to groundwater level declines in most parts of the country. Kabul, the largest city of Afghanistan, is the capital city with a population of 4.5 million and the fifth fastest-growing city in the world. The city has observed groundwater level declines of 5-10 meters (m) since 1980. Decline of about 30 m has also been observed in one of the monitoring …

Integrated Analysis Of Flow, Form, And Function For River Management And Design Testing, Belize A. Lane, Gregory B. Pasternack, Samuel Sandoval-Solis

Civil and Environmental Engineering Faculty Publications

The extent and timing of many river ecosystem functions is controlled by the interplay of streamflow dynamics with the river corridor shape and structure. However, most river management studies evaluate the role of either flow or form without regard to their dynamic interactions. This study develops an integrated modelling approach to assess changes in ecosystem functions resulting from different river flow and form configurations. Moreover, it investigates the role of temporal variability in such flow–form–function trade‐offs. The use of synthetic, archetypal channel forms in lieu of high‐resolution topographic data reduces time and financial requirements, overcomes site‐specific topographic features, and allows …

Operational Impact Of Shadow Evacuation On Regional Road Networks During Short-Notice Emergency Evacuations, Efe Emre Tuncer

LSU Master's Theses

As part of evacuation planning, development of effective tactical and operational strategies are essential to safely and efficiently mobilize the public away from the threat. Evacuations are classified by the time between notification and the anticipated arrival of the threat which can be categorized as short, or no-notice emergencies. Emergencies involve the computation of the time required to evacuate the area of risk, which is the time to clear a radius of up to about 10-miles around the nuclear power plant, known as the emergency planning zone (EPZ). These evacuation time estimates (ETE) also account for the evacuation of the …

Experimental Investigation Of And Constitutive Model For The Thermo-Poro-Mechanical Deformation Of Granular Salt Under Hydrostatic Compression, Brandon C. Lampe

Civil Engineering ETDs

The influence of pore pressure and porosity on the ductile deformation of granular salt was experimentally investigated under hydrostatic compression. Confining and pore pressures were independently controlled while granular salt samples exhibited rate-dependent deformation that resulted in large decreases of sample volume and porosity. The sample deformation rates were observed to correspond with both the sample porosity and the pressure difference between the confining and pore pressures. Post-test observations revealed that the reduced porosity was caused by the solid particles deforming in a ductile manner. Insight into the cause of ductile deformation was gained by considering the local stress distribution …

Evaluating Classifiers' Optimal Performances Over A Range Of Misclassification Costs By Using Cost-Sensitive Classification, Ramy Al-Saffar

LSU Master's Theses

We believe that using the classification accuracy is not enough to evaluate the performances of classification algorithms. It can be misleading due to overlooking an important element which is the cost if classification is inaccurate. Furthermore, the Receiver Operational Characteristic (ROC) is one of the most popular graphs used to evaluate classifiers performances. However, one of the biggest ROC’s shortcomings is the assumption of equal costs for all misclassified data. Therefore, our goal is to reduce the total cost of decision making by selecting the classifier that has the least total misclassification cost. Nevertheless, the exact misclassification cost is usually …

Definite Indefiniteness Of "Molecular Weight" As A Claim Term For Polymer-Related Patents, Ping-Hsun Chen

The Journal of Business, Entrepreneurship & the Law

The molecular weight of a polymer is not just a number for a single molecule. In fact, molecular weight measurement is based on a large volume of molecules of the same polymer. Due to the non-uniformity of molecular weights, there are several methods to measure an “average molecular weight” of a polymer. Unfortunately, the Federal Circuit in Teva Pharms. USA, Inc. v. Sandoz, Inc., 789 F.3d 1335 (Fed. Cir. 2015), held that the term “molecular weight” in several polymer claims was indefinite, because the term could mean either peak average molecular weight, number average molecular weight, or weight average molecular …
