Tato práce se zabývá optickým chováním LCD displejů, které se používají v kokpitech v automobilovém průmyslu. Konkrétně se zaměřuje na analýzu možných vlivů výrobního prostředí na rovnoměrnost černé homogenity displejů pomocí statistických metod. Během experimentů jsou zkoumány údaje o černé homogenitě a rovinnosti vstupního materiálu i polotovarů ...
In laser etching of ITO glass, the warpage due to workpiece positioning causes breakpoint or deformation of micron-scale etching circuits. Based on traditional laser etching, a micro-airflow array pressurization is proposed by using a micro-flow air bearing through airflow positioning. The objective is to achieve high-precision laser etching by pre...

Das VGF-Verfahren ist ein moderner Prozess zur Züchtung von Einkristallen, der Grundlage für nahezu alle elektronischen Anwendungen. Die sukzessive Erstarrung der Schmelze zum Einkristall wird dabei durch geeignete Ansteuerung der als Aktoren in der Anlage zur Verfügung stehenden Heizer realisiert. Dieses Regelungsproblem ist Gegenstand des Beitrag...

The purpose of this paper is to propose an energy management strategy (EMS) based on flatness control method for a standalone hybrid photovoltaic-battery system. The goal of the proposed method is to use non-linear flatness theory to develop an efficient EMS in order to provide a stable DC bus voltage and an optimal power sharing process between th...

As part of the structural inspection, compliance with the specified flatness tolerances according to DIN (in particular DIN 18202:2019-07) has to be checked. Today, the monitoring of the flatness is carried out mainly with levelling instruments and tacheometers. However, these measuring methods are time-consuming, as stacking out the measuring grid...
In this paper, we completely describe flatness of the simplest class of interconnected systems: we consider an interconnection of (controllable) single-input linear subsystems in dimension two with a star topology and a linear interconnection dynamics (with no inputs acting directly on the interconnection variable). First, we observe that even if e...
The wind tower block is welded with the flange to assemble the wind tower. The inherent strain due to local heating and cooling of the weld affects the flatness of the flange. Therefore, line heating is performed to satisfy the design criteria of the flange flatness, but the work variables depend on the operator’s empirical judgment. This study pro...
We consider linear one-dimensional strongly degenerate parabolic equations with measurable coefficients that may be degenerate or singular. Taking 0 as the point where the strong degeneracy occurs, we assume that the coefficient a = a(x) in the principal part of the parabolic equation is such that the function x → x/a(x) is in L p (0, 1) for some p...
Diplomska naloga preučuje ravnost debele pločevine jekla AISI 304 po vročem valjanju. Delo zajema tehnološko pot izdelave debele pločevine od valjalnega stroja pa vse do skladiščenja pri sobni temperaturi. Posebej sem preučil delovanje vročega ravnalnika, njegovo delovanje in vpliv na ravnost plošč. Vsi preizkusi so potekali na industrijski ravni v...

Two-dimensional (2D) van der Waals materials are subject to mechanical deformation and thus forming bubbles and wrinkles during exfoliation and transfer. A lack of interfacial "flatness" has implications for interface properties, such as those formed by metal contacts or insulating layers. Therefore, an understanding of the detailed properties of 2...
