This paper deals with the influence of different apertures shape in stencil on mechanical shear strength, electrical resistance and insulation distance. In the experiment, the SMD chip components 0805 were assembled on flexible substrate by electrically conductive adhesives (MG 8331S, CA 315...

The TOTEM collaboration has measured the elastic proton-proton differential cross section dσ/dt at √s = 13 TeV LHC energy using dedicated β ∗ = 90 m beam optics. The Roman Pot detectors were inserted to 10σ distance from the LHC beam, which allowed the measurement of...

Digitization, modern technology (IoT), development of sensor technology and data processing in recent years it has started to promote also in the agricultural sector (crop, livestock production) in the Czech Republic Republic. The aim of the paper is to explain the general principles&#x...

The paper describes the development, validation, and use of UWB1 code intended for fast calculation of nuclear fuel depletion in burnable absorber research. The degree of effectiveness of burnable absorbers in the form of natural abundance elements, nuclides, and their combinations are ...

Partial discharges are one of the most commonly occurring physical phenomena that can have a negative effect on the overall life of electrical equipment. The most basic types (besides surface and internal) are discharges occurring in places with a small radius of curvature. At ...

Purpose – The paper aims to describe the modeling of the induction-assisted laser welding process taking into account the keyhole effect and phase changes in the material. Design/methodology/approach – A sophisticated mathematical model of the above heat treatment process is presented,&...

Traditional three-phase voltage-source inverters supplied by constant dc-link voltage usually utilize the space vector PWM to achieve maximum output voltage. This paper deals with optimization of inverter leg voltages using linear programming method. System definition is based on the relationship ...

Production companies are adopting new methods for the improvement of their managing production processes. The cost, quality and time are still key important attributes for process improvement. This is reason why the Business Process Management (BPM) is the core of management in differen...

Rapid International Scientific Experiment Satellite (RISESAT) is a small Japanese experimental Earth-observing, science and technology demonstration satellite. One of the scientific instruments onboard is a miniature radiation monitor telescope RISEPix with two Timepix detectors, developed and built at the...

We present a newly developed modular and multiplatform acquisition and control package dedicated for high performance Timepix3 pixel detector. The software package was originally developed for operation at ATLAS experiment. Afterwards, it was further extended as an independent package for general...

This paper is focused on the study of copper thick film metallization on AlN. The copper metallization was realized by Thick Printed Copper (TPC) technology. The copper films were printed with a new adhesion copper paste designed for both AlN and Al2O3 substrates. Scanning ele...

Composites prepared from low-density polyethylene (LDPE) and tubular halloysite nanotubes (HNTs) with different contents of HNTs were comprehensively tested. HNTs were utilized to suppress the intensity of heat release from the ignition of LDPE. The results revealed that the large polarity d...

Possibilities of using surrogate techniques for modeling selected strongly nonlinear coupled problems of heating are evaluated. The main purpose is to significantly reduce the computing time in the case of computations of many variants of a given task by the finite element method o...

Cogeneration power plants have already been operated in the Czech Republic for several decades. These cogeneration power plants have been mostly operated with original technologies. However, these original technologies have to be continuously innovated during the entire operation time. This paper...

This paper is focused on the thick-film power resistors with copper terminals. These terminals are created by the new Thick Printed Copper (TPC) technology. This technology is based on sequential screen printing and firing of copper paste in nitrogen atmosphere on an alumina substr...

Prion disorders are fatal neurodegenerative diseases caused by the autocatalytic conversion of a natively occurring prion protein (PrPC) into its misfolded infectious form (PrPTSE). The proven resistance of PrPTSE to common disinfection procedures increases the risk of prion transmission in medic...

Autonomy in vehicles is a rapidly expanding technology that is of interest in many major car companies. Autonomous driving enables safer journeys by removing human error in driving, as well as reducing driving time and fuel consumption by optimizing the engine and brake actuation.&...

Cardiac output (CO) is a key parameter in the assessment of cardiac function, and its measurement is fundamental to the diagnosis, treatment, and prognostic evaluation of all heart diseases. In this paper the linear and nonlinear models for noninvasive estimation of CO are presente...

The paper deals with a problem of modeling of dynamic systems. The proposed approach to the problem solution is based on modified Tellegen’s theorem well known from electrical engineering. The novelty of this approach is that it is based on the instantaneous power calculation ...
