Manpower Cost Analysis Of A Distributed En Route Support Structure Versus A Consolidated En Route Support Structure, Phillip M. Rehmert
Theses and Dissertations
The United States military has developed an en route support structure for airlift requirements to deploy and sustain combat forces in conflict. The Air Mobility Command (AMC) is interested in determining the cost effectiveness of two distinctly different en route structures, in particular, the cost effectiveness of one large facility versus supporting combat forces with many smaller facilities. With the current operational tempo, continued analysis must be accomplished to determine if a smaller footprint is possible in the deployment and sustainment scenarios of conflicts seen today; conflicts more centered on a leaner and faster deployment force. This research examines the …

Conference papers
Abstract Since the 1990’s, there has been a rapid rise of Public Private Partnerships (PPPs) across the world. Governments in developing as well as developed countries are increasingly using this procurement method to bridge the much needed infrastructure gap. PPPs are seen as an important tool for producing an accelerated and larger pipeline of infrastructure investments, and catching up with the infrastructure deficit. Arguably, this is why developed and especially developing countries are very keen on PPP models. This paper will compare the PPP procurement process followed in Europe compared to India and presents a thorough review of literature on …

The importance of the construction industry to nation building necessitates that project implemented achieves project success. However, studies and evidence have shown that there is a low probability in consistently achieving project success. Nevertheless, it seems that the definition of project success and how to achieve project success is quite illusive. For more than a century, researchers have been grappling with its definition but the concept remained ambiguous. From the early identification of time, cost and quality as elements of project success, researchers have added many other outcomes and objectives including stakeholders, project manager, communication, leadership, project management, organization structure, …

Biomechanical Evaluation Of Modified Track Shoes, Marlon Alberetos Greensword
LSU Master's Theses
Track and field runners, especially sprinters and mid-distance runners, face many problems due to walking in spike shoes. Due to the fact that track and field spike shoes are designed specifically for running, the runner’s feet remain in an uncomfortable, flexed position when walking between workouts and races. Problems caused by the dangerous foot-positioning include, but are not limited to, the following: back pain, shin splints, bone spurs, blisters, and overall decreased level of running performance. Over time, runners wearing improper footwear for walking may face chronic injuries such as plantar fasciitis, shin splints, Achilles tendinitis, chondromalacia, and iliotibial band …

An Operational Policy For A Single Vendor Multi Buyer Integrated Inventory Supply Chain System Considering Shipping Time, Chiranjit Saha
LSU Master's Theses
Since its introduction, the concept of integrated inventory supply chain has received a considerable amount of attention. The majority of studies in the last three decades revealed an increase in holding cost as product moves further down the chain or up the chain. A recent study Hoque (2008) considered vendor’s setup cost and inventory holding cost. Some research also considered fixed transportation cost, which is unrealistic. This study focuses on a single-vendor, multi-buyer scenario and presents three models. First, two models illustrate the transferring of equally-sized batches. Then, a third model considers the transferring of unequally-sized batches in a lot. …

A Study Of Hough Transform For Weld Extraction, Rakesh Gunaseelan
LSU Master's Theses
The process of joining metals is called welding. At times, selecting a poor quality material or improper usage of welding technologies may cause defects in welded joints. Some of these welded joints have to be tested nondestructively, because their failure can cause lot of damage, for instance in power plants. Radiography is a very common method for non-destructive testing of welds. It is done by certified weld inspectors who have knowledge about weld flaws, looking at the radiograph of the welded joint with naked eye. The judgment of the weld inspector can be biased; subjective, because it is dependent on …
