It is commonly accepted that for the analysis of wood beams, the neutral axis coincides with the centroid of the beam. Although this assumption is used in analysis, wood is not an isotropic material, as it has different elastic properties in the tangential, radial and longitudinal directions, nor is it...
In the United States there are currently two different options for providing safety audits to roadway projects. Traditional audits can be conducted using procedures similar to those in the United Kingdom, or those similar to Australia and New Zealand (Austroads). Another option for conducting safety audits is to use the...
Because of the increased need for sustainable construction in an ever urbanizing culture, new sustainable drainage systems are being developed and implemented. Bioswales are becoming
an increasingly popular form of sustainable urban drainage used for parking lots and
subdivisions. But little is known regarding the effectiveness of bioswales in really...

The educational environment is filled with different types of students, all with diverse learning styles. The Meyers-Briggs Type Indicator and Kolb’s Theory of Experiential Learning are generally accepted methods for determining and assessing a person’s preferred method of information processing. There has been research that suggests learning styles are specific...
While damages due to ponding are common and expensive, provisions for design and
construction of flat roof systems lack guidance regarding these loads. The goal of this research is
to present methods of designing or building flat roofs that are less vulnerable to this condition. An
investigation of the literature,...
Aesthetics should be emphasized as much as possible in a design project without
exceeding scope, budget, or schedule to satisfy the stakeholders involved. There
is a rising trend of increased emphasis on aesthetics. This trend of using various
techniques to help structures blend in or contribute to the surrounding
environment...
Cob is an earthen building material composed of sand, clay and straw. Though cob homes
are presently being built in the Pacific Northwest, there is no applicable building code for this
material. The purpose of this study is to establish estimates for the major engineering parameters,
including both average values...
The intent of this thesi s is to prove whether or not simple moving averages can be
used to predict the future price performance of stocks and outperform the buy-and-hold
method of investing in the stock market. The importance of this research is that if moving
averages can predict future...
This study considered collision data for Seattle, Washington and Portland, Oregon
in order to determine whether or not red light cameras are effective in reducing red light
running collisions. Red light running is extremely dangerous and is a leading cause of
urban automobile collisions in the United States. Red light...
