For the purpose to facilitate development of high-speed Spindle Units (SUs) running on rolling bearings, we have developed a beam element model, algorithms, and software for computer analysis of thermal characteristics of SUs. The thermal model incorporates a model of heat generation in rolling bearings, a model of heat transfer from bearings, and models for estimation of temperature and temper...

We prove a new lower bound on the critical density ρc of the hard disk model, i.e., the density below which it is possible to efficiently sample random configurations of n non-overlapping disks in a unit torus. We use a classic Markov chain which moves one disk at a time, but with an improved path coupling analysis. Our main tool is an optimized metric on neighboring pairs of configurations, i....

In the multiple authors case, the name with ∗ is the speaker.

Cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. By introducing cloud computing in 2012, the school has managed to ease access and sharing, enhance collaboration between teachers and school management and was able to adopt and consummate another digital competence in order to benefit our school curriculum. Another crucial ben...
