Physic learning usually requires more observation to form certain knowledge and concepts. does not only consist of a collection various or facts that can be memorized, but also consists an active process using the mind in studying natural phenomena cannot explained. Physics subject is one keys success increasing ability adapt change enter world technology. Therefore, ways are needed convey mate...

Industry is increasingly turning to predictive maintenance by using digital twins (DTs) follow and predict evolution of mechanical system. This article presents, compares discusses two DTs diagnose wear bush bearings under dynamic loads. The first DT driven a model based on data analysis statistical process control (SPC). second physical laws: Boussinesq's Archard's equations. Both are fed reco...

High power targets are one of the major issues in an accelerator complex for future HEP physic studies. The paper will review status of studies worldwide. It will focus on the status of the MERIT mercury-jet target experiment at CERN.

In this work we review the status of tree-level vacuum stability in general two-Higgs doublet models. We also discuss the problem of Normal minima in some classes of potentials. In some of these potentials, Normal minima can coexist leading to potentially dangerous physic scenarios as, for instance, a two step spontaneous symmetry breaking.

To determine the area of glass formation in system As2S3-ErS were synthesized alloys range concentrations 0-30 mol. % ErS. The methods physico-chemical analysis differential-thermal (DTA), X-ray phase (RFA), microstructural (MCA) analyzes, as well measurement microhardness and density determined studied them physic?-chemical propertes. It is established that on basis As2S3 during slow cooling r...
