Applications of force actuators and variable stiffness systems with base isolation
(Massachusetts Institute of Technology, 2008)
Recent developments have occurred that limit the effectiveness of conventional strength-based structural design. First, there has been a trend towards designing more flexible structures that require increased emphasis on ...
Improving parameterization of scalar transport through vegetation in a coupled ecosystem-atmosphere model
(Massachusetts Institute of Technology, 2008)
Several regional-scale ecosystem models currently parameterize subcanopy scalar transport using a rough-wall boundary eddy diffusivity formulation. This formulation predicts unreasonably high soil evaporation beneath tall, ...
Pile design using wave equation analysis program application in offshore wind farm
(Massachusetts Institute of Technology, 2008)
Pile driving has been of interest to geotechnical engineers for a very long time. Originally, empirical pile driving formulae were used to interpret pile displacements caused by a hammer blow. Smith (1960) proposed a ...
Optimization of stiffener placement for thin plate buckling
(Massachusetts Institute of Technology, 2008)
Stiffened plates are a common component in many structures, from plate girders and box girder bridges to ships and offshore structures. Plates and stiffened plates buckle into doubly curved surfaces, substantially complicating ...
Financing infrastructure projects
(Massachusetts Institute of Technology, 2008)
Infrastructure is of great importance to the development and economic growth of communities. Due to the increased demand on sophisticated infrastructure, governments' budgets are not anymore able to satisfy this growing ...
General overview of the Nigerian construction industry
(Massachusetts Institute of Technology, 2008)
The purpose of this study is to investigate and provide a general overview of the Nigerian construction industry, its role in the national economy, the main participants in the industry, the problems that they face, and ...
Price competition in the top US domestic markets : revenues and yield premium
(Massachusetts Institute of Technology, 2008)
Since 2000 the US airline industry has gone through a severe crisis which initiated important changes in the competitive environment of the industry. The economic downturn, the fierce competition between Legacy carriers, ...
All fired-up about coal : technology & policy recommendations for the 2030 United Kingdom energy strategy
(Massachusetts Institute of Technology, 2008)
Given United Kingdom (UK) carbon dioxide emissions policies that direct attention at the electricity segment, the focus is on the largest electricity polluter, coal, and the immediately pressing issue of UK coal policy. ...
Aquatic microenvironments in bacterial ecology and diversity
(Massachusetts Institute of Technology, 2008)
Molecular surveys have revealed tremendous bacterial diversity in the world's oceans; yet how do these diverse bacteria with the same essential nutrient requirements co-exist in the same environment? This study examines ...
Real-time Multi-period truckload routing problems
(Massachusetts Institute of Technology, 2008)
In this thesis we consider a multi-period truckload pick-up and delivery problem dealing with real-time requests over a finite time horizon. We introduce the notion of postponement of requests, whereby the company can ...
