The influence of load distribution on the reliability analysis of lumber properties data
… on light frame structures, distributions of maximum lifetime roof snow load and maximum lifetime floor live load were developed for use in differential reliability analyses of lumber properties data. The dead load was combined with the live load to obtain the total roof or floor load. …

Influence of lumber property correlations on roof truss reliability
… simulated trusses were subjected to a 50 year maximum lifetime snow load distribution plus a dead load distribution. Bending, tensile, and compressive strength properties were modeled by a weighted least squares regression analysis. Modulus of elasticity was used as the independent strength …

Cross-layer design for network performance optimization in wireless networks
… significant improvement on throughput and lifetime. In paper 3 and paper 4, an interference model is proposed and a transmission scheduling scheme is presented to minimize the end-to-end delay. This scheduling scheme is designed based on integer linear programming and involves interference …

Multiple Asteroid Retrieval Mission
… a spacecraft max life span. Explicitly, the maximum lifetime of the spacecraft fleet is set at 30 years. A fuel supply-chain is proposed and designed so that each spacecraft is refueled before departing for each asteroid. To maximize access to the number of asteroids and retrievable mass for …

Directional Communications to Improve Multicast Lifetime in Ad Hoc Networks
… designed to optimize max-min multicast path lifetime for directional antenna equipped networks in the presence of interference. The MILP is utilized to perform a comparison directional antenna use for signal transmission and reception. Results indicate that directional reception is slightly …

A spectroscopic investigation of novel doped glasses for active infrared devices
… is shown in this work to increase fluorescence lifetimes. However, the addition of >5% SnO<sub>2</sub> causes increased infrared absorption which would outweigh advantages gained by the increased lifetime. Thulium-doped tin silicate glass-ceramics were investigated for the first time, and show a …
