A procedure has been developed to optimize designs of metal-clad post-frame buildings using an expert system. The novel part of the study is the development of a procedure that extends the solution of an engineering problem from a conventional algorithmic Computer Aided Design (CAD) program to be used by the...
Thesis explores the ways in which Information and Communication Technology (ICT)use, specifically that of telephones and the Internet, impacts the lives of Eritrean refugees in Rome, Italy. Informal interviews, semi-structured interviews, and participant observation were carried out in a 'center of second reception.' Results show that information obtained through the...
Metal-plate-connected wood trusses with semi-rigid joints were investigated by the matrix method of structural analysis. The element-stiffness matrix and fixed-end forces of an individual member with one or both ends semi-rigid were derived as modifications of the idealized cases. The case of unequal elastic connections at two ends of a...
Probability density functions (normal, lognormal, and three-parameter Weibull) were used to characterize strength data for three different types of metal-plate-connected wood truss joints (web at the bottom chord, tension splice, and heel). Modulus of elasticity (MOE) of the lumber used to fabricate the joints was also characterized. A probability-plot technique,...
Load-displacement characteristics and failure modes of metal-plateconnected wood truss joints are presented. Tension splice, heel, and web at the bottom chord joints are fabricated using southern pine (SP) no. 2 lumber and 20-gage punched metal plates. These joints are tested with a newly developed testing appratus that allows the testing...
This analysis explores potential changes in the behavior of Oregon's Supplemental Nutrition Assistance Program (SNAP) participants after the 2008 recession. I examine this using individual-level administrative data from the State of Oregon in a linear probability model and a duration model. After controlling for a standard set of factors known...
European hazelnut, Corylus avellana L., is the only economically important nut crop
in the family Betulaceae. One of the threats to the hazelnut industry in the Pacific
Northwest is the fungal disease eastern filbert blight (EFB) caused by the
pyrenomycete Anisogramma anomala. Host genetic resistance to EFB identified in the...
Ten full size (3.7 x 4.9 m) plywood roof diaphragms were constructed using metal plate connected (MPC) common and hip wood trusses or joists, typical of single-family dwelling (SFD) construction. The specimens included three gable roof slopes of 33, 67 and 100%, a hip roof of 33% slope, and a...
