Lightweight Steel Frames (LSF) in building construction are becoming more popular due to their fast, clean, and flexible constructability. Typical LSF wall panels made of cold-formed thin-walled steel lipped channel studs with plasterboard linings. Due the high thermal conductivity steel, these components must be well engineered covered against unintended bridges. Therefore, it is essential inv...

Oil and gas transmission pipelines are critical items of infrastructure in providing energy sources to regions and countries. Steel pipes are commonly used which can be subject to both internal and external corrosion. This paper presents an advanced nondestructive inspection technique for detection of oil-gas pipeline corrosion defect. The Pulsed Eddy Current (PEC) method has been successfully ...

Between 1990 and 1998, the author published five conference papers which described the gradual development of a simple theoretical model for predicting the sound insulation of building partitions. The first aim was to extend Sharp’s model for cavity walls to cavities without sound absorption. The second aim was to remove the reported over prediction of Sharp’s model for cavity walls. The third ...

We report the performance of a kinetically enhanced copper-vapor laser of active dimensions 32-mm inner diameter by 1-m long as a function of the plasma tube thermal insulation. By reducing the insulation to levels much lower than typically used for conventional copper-vapor lasers, the input power for maximum steady-state output increased from 5.9 to 7.4 kW, whereas the laser wall-plug efficie...

The traditional brick bungalow is not conducive to long-term grain storage because of its poor thermal insulation. In this paper, a new type wall element for bungalows with both load-carrying and insulation functions, called “Structure-Insulation” integrated panel (SIW), proposed improving the environment. To study reliability SIW under multivariable randomness availability different zones, fin...
