The aftermath of the pandemic in 2020 shocked country’s economy, but at same time, desire to keep business allowed, record completely rebuild usual patterns behavior implementation processes across all sectors economy. inability go work, solve everyday issues, carry out a commodity-money exchange, allowed remote service model burst so rapidly. construction mechanism for formation work on basis ...

Patients with coronary artery disease face increased risks when they undergo noncardiac surgery. This is attributable to the cardiovascular stress imposed by the surgical procedure and the effects of anesthetic agents on the cardiovascular system. Several approaches to managing patients with coronary artery disease before, during, and after noncardiac surgery include "prophylactic" myocardial r...

This paper describes a method for the determination of the four grasping points that are necessary to get a force closure grasp for a planar object considering frictionless contacts. The geometric model of the object is assumed to be unknown. The proposed approach starts from the object boundary obtained from the binary digitalization of an object image, and then uses the dual representation of...

Traditional concepts for manufacturing process optimization, e.g., Lean Production and Total Quality Management, represent management-driven and experience-based approaches. The increasing use of cyber-physical systems as well as the digitalization of manufacturing operations management by manufacturing execution systems (MES) lead to enormous amounts of structured and unstructured manufacturin...

We investigate in this paper problems of theoretical foundation of collocations and mechanical quadratures methods for approximate solution of singular integral equation systems in the case, when their symbols have on the integration contour a finite set of integer degree zeroes. We consider the case when equation digitalization points are taken in such a way that each point of the contour can ...

In this paper we present three experiences about combining 3D digitalization techniques for cultural heritage documentation. Retable of Bouro (Portugal) is a big and complex wood structure from the XVII century part of the Monastery of Santa Maria do Bouro. An urgent conservation and restoration program was promoted in order to prevent further damage in the retable. A complete 3D graphical reco...

This paper introduces a digitally performed current mode and voltage control for the dc-dc step down converter based on voltage to frequency converter where the average values of inductor current and output voltage are obtained. These current and voltage measurement are realized by the voltage control oscillator (VCO) and counters (digital integrator). Such an approach enables full digitalizati...

During the years 1970-1973, the Laboratory of Information Processing Science at the Helsinki University of Technology carried out the Computer Graphics Project (CGP). The activities focused on the problems of producing newspaper text, advertisements, and complete pages using interactive computer graphics. The project and its commercial spinoff, Typlan, as well as the BUNPAPS continuation projec...
