in this study, we have theoretically investigated designing possibility of a seismometer using fiber bragg grating (fbg) and metal bellows pairs attached on a mechanical system. this new seismometer can record earthquakes according to sensitivity of fiber optic to changes in physical parameters such as stress and strain. firstly, in order to understand the quantity and quality of sensor perform...

The article provides morphological and functional characterization of the new coronavirus (COVID-19) based on latest scientific research data, study biological properties, epidemiology course infectious process in humans, some issues treatment prevention.

In this paper we describe the product modeling techniques that we use for the development of a computer-aided decisionmaking tool for the building industry. We start with an introduction to modeling and a brief description of the goals and scope of the project, and follow with an extensive presentation and discussion of the modeling techniques employed. We conclude with a brief description of o...

The Talbot effect is usually modeled using the Helmholtz equation, but its main experimental features are captured by solution to free Schr\"odinger equation with Dirac comb as initial datum. This simplified description a consequence of paraxial approximation in geometric optics. However, it heuristic that not mathematically well justified, so K. I. Oskolkov raised problem "mathematizing" it. W...

peri-implantitis is a site-specifi c infectious disease that causes an infl ammatory process in soft tissues, and bone loss around an osseointegrated implant in function. the etiology of the implant infection is conditioned by the status of the tissue surrounding the implant, implant design, degree of roughness, external morphology, and excessive mechanical load. the microorganisms most commonl...
