M. Stańczyk, T. Figlus, The Silesian University of Technology, Faculty of Transport Katowice, Poland In the work the influence results of two different hardening coolant agents on the basic mechanical proprieties and microstructure of the round hot rolled bars were presented. The bars of 42CrMo4 steel were exposed to analysis, and for those bars in the hardening process, water and modern pro-ec...

In this paper, we define a general class of tensegrity structures consisting of both compression members (ie bars) and tensile members (ie cables). For a given number N of bars, we define the topological structure which is necessary to establish a tensegrity. Necessary and sufficient conditions for prestress mechanical equilibria of the tensegrity are then provided in terms of a nonlinear funct...

Error bars for MCMC are harder than for direct Monte Carlo. It is harder to estimate error bars from MCMC data, and it is harder to predict them from theory. The estimation and theory are more important because MCMC estimation errors can be much larger than you might expect based on the run time. The fundamental formula for MCMC error bars is as follows. Suppose Xk is a sequence of MCMC samples...

A fItrite element scheme (together with a conjugate gradient algorithmj is demonstrated to be a very effective method for analyzing general elastoplastic torsion of prismatic bars posed as quadratic programming problems. Solutions for bars with elliptical and Sokolovsky’s oval cross-sections are presented. The solutions for the elliptical bars agree with the existing elastic and limit plastic s...

The use of Glass Fibre Reinforced Polymer (GFRP) bars is considered an alternative option in reinforcing concrete structures instead of conventional steel bars especially in harsh severe environments, due to their mechanical properties and physical characteristics. GFRP bars offer many advantages over steel counterparts such as corrosion resistance, high tensile strength, low weight and electro...

I present a study of the sizes (semimajor axes) of bars in disc galaxies, combining a detailed R-band study of 65 S0–Sb galaxies with the B-band measurements of 70 Sb– Sd galaxies from Martin (1995). As has been noted before with smaller samples, bars in early-type (S0–Sb) galaxies are clearly larger than bars in late-type (Sc–Sd) galaxies; this is true both for relative sizes (bar length as fr...

O n 29 March 2004, Ireland became the first country in the world to implement legislation creating smoke-free enclosed workplaces that included bars and restaurants. While the legislation involved all workplaces, with minor exceptions, national and international media attention focused on how the legislation would be implemented in bars. Many commentators looked on in disbelief and suggested th...

BACKGROUND The UK government claims that between 10 and 30% of pubs and bars will be exempt from proposed legislation to achieve smokefree enclosed public places across England. This arises from the contentious inclusion that pubs and bars that do not prepare and serve food and private members clubs, will be able to allow smoking. We aimed to survey pubs and bars across the North West of Englan...

Along with a brief analysis we present data obtained from BVRI and Ks images of a sample of 19 galaxies (18 barred and 1 unbarred) which will be further explored in a future paper. We measured the lengths and colors of the bars, created color maps and estimated global color gradients. Applying a method developed in a companion paper, we could distinguish for 7 galaxies in our sample those whose...

Weightlifting training and competition involves lifting a revolving shaft bar loaded with weights. The design of a bar and the location of the weights result in bar deformation during lifting tasks. Because there are many manufacturers of weightlifting bars, the actual deformation of a bar may vary, depending on the steel alloys used. A modified 4-point static bending test was used to assess de...
