Abstract. A detailed analysis of the adiabatic-piston problem reveals peculiar dynamical features that challenge the general belief that isolated systems necessarily reach a static equilibrium state. In particular, the fact that the piston behaves like a perpetuum mobile, i.e., it never stops but keeps wandering, undergoing sizable oscillations, around the position corresponding to maximum entr...

We are developing a technique to measure segment misalignment of large telescopes based on wavefront estimation using phase-diverse (inand out-of-focus) images. We report the current results of an experiment to measure piston errors on the Keck II primary segmented mirror, through atmospheric turbulence, using phase-diverse phase retrieval. The segment piston errorss are separated from the rand...

RF-based location tracking in industrial environment possesses many challenges due to the complex propagation condition. This paper will address some of the problems in this environment. Firstly, we evaluate the performance of RF-based tracking in a harsh environment, i.e. in a car manufacturing plant. Secondly, the research presents a comprehensive study of an algorithm that utilises Bayesian ...

In this study, a tension extension spring fatigue machine was designed and manufactured. The force applied by jaws were driven pneumatic piston. air pressure is 6 bar that acquired from local network. maximum to meet at least 12 kN. Thereby, multiple quantity of springs can be tested simultaneously. adjusted adjuster. cycles controlled an electronic circuit. also complement desired number cycle...

Three strains of Geobacillus stearothermophilus (designated A1, P3, and D1) were isolated from a New Zealand milk powder manufacturing plant. Here, we describe their draft genome sequences. This information provided the first genomic insights into the nature of G. stearothermophilus strains present in the milk powder manufacturing environment.

This paper describes the application of discrete event simulation to study continuous material flow. Logistics is an integrated part of most manufacturing companies. The purpose of this study is to determine the required logistics operations to allow continuous operations of a chemical manufacturing plant. The application has been used to provide critical decision support.
