Welding Journal - October 2012
There are a wide range of important applications for metal tube materials in various fields. The production process of high-frequency longitudinally welded pipe includes first using a roller to coil the long steel strips of a certain size into a cylinder shape, and then join them by heating the steel materials at the welding edge with a high-frequency welding machine — Fig. 1. The processes inc...

One of the most important tasks in robust design is to select an appropriate system output response in the study. The quality of this selection will greatly affect the effectiveness of the robust design project. Currently, this selection process is more like art than science. By using TRIZ and Axiomatic Design principle, several new approaches to enhance robust design are developed. These appro...

Figure 1 Atmospheric layers environment. We learned that scientists now estimate 3-5% of the ozone layer, which protects us from exposure to ultraviolet rays, has been destroyed by chlorofluorocarbons (CFCs), increasing our risk of cataracts and skin cancer.' (See Figure 1.) But what about the volatile anesthetic agents, hydrochlorofluorocarbons (HCFCs), which closely resemble the CFCs? Are the...

Two kinds of perceptual priming (word identification and word fragment completion), as well as preference priming (that may rely on special affective mechanisms) were examined after participants either read or named the colors of words and nonwords at study. Participants named the colors of words more slowly than the colors of nonwords, indicating that lexical processing of the words occurred a...

We thank Dr. Stern (1) for his interest in our work (2). We agree that risk distribution curves are a valuable addition in the assessment of risk prediction models, particularly in the interpretation of reclassification measures. Two identical risk distribution curves that differ in location reflect models with different calibration, and 2 risk distribution curves that differ in dispersion refl...
