Producing nanofibers of a desired predetermined diameter is important for all applications where the nano-sized dimension plays a key role. In this research, nanofibers from a blend of lignin and recycled poly(ethylene ...

Throughout their service life, highway bridges are subject to progressive deterioration in performance; an issue that may render the use of these facilities unsafe at some point in time. Over the last few decades, there ...

The design optimization considering the system reliability of a structural system is a computationally challenging task. This is especially the case in an indeterminate structure that has many possible modes or paths to ...

The casing treatment is an effective method for increasing the stall margin of compressors and enhancing the flow distribution at the blades tip. The present numerical study focuses on making an optimization of the casing ...

Three variations of the particle swarm optimization (PSO) method are used to solve the boundary inverse heat conduction problem, in one, two, and three dimensions. Both steady and transient problems are studied. It is shown ...

The lifetime reliability of existing structures may be quantified by lifetime functions. Redundancy is an additional type of structural performance indicator that is defined as a measure of warning available prior to system ...

The need to design and construct structural systems with adequate levels of reliability and redundancy is widely acknowledged. It is as crucial that these desired levels are maintained above target levels throughout the ...

Continuous progress in structural reliability theory and methods, in addition to the evolving advances in optimization solution techniques, drives the steady development of reliability-based structural design process. The ...

The weighted average simulation technique is one of the newest techniques that showed promising capabilities in solving structural reliability problems. In this paper, a modification to the weighted average simulation ...

The waste management processes typically involve numerous technical, climatic, environmental, demographic, socio-economic, and legislative parameters. Such complex nonlinear processes are challenging to model, predict and ...
