  W pracy badano stany wzbudzenia elektronowego, powstające z udziałem dwóch molekuł. Dzięki doborowi odpowiednich materiałów na warstwę przewodzącą dziury (pochodna trójfenyloaminy: m-MTDATA) i elektronów (pochodna oksadia-zolu:PBD) w cienkowarstwowej diodzie EL stworzono szczególnie dogodne warunki do generacji ekscypleksów (M-MTDATA-PBD) i wysokowydajnej (>1% foton/e-lektron) emisji ekscypleksowej.

• Effect of the let-through energy of overcurrent protective devices on the temperature of conductors during short-circuits

  Publikacja

  • S. Czapp
  • D. Kowalak

  - Przegląd Elektrotechniczny - Rok 2021

  The scope of the verification of low-voltage systems covers the earth fault loop impedance measurement. This measurement is usually performed with the use of low-value current meters, which force a current many times lower than the one occurring during a real short-circuit. Therefore, the international standard recommends consideration of the increase of resistance of conductors with the increase of temperature, which may occur...

  - RADIOENGINEERING - Rok 2020

  This paper presents a new approach for variability analysis of microwave devices with a high dimension of uncertain parameters. The proposed technique is based on modeling an approximation of system by its poles and residues using several modeling methods, including ordinary kriging, Adaptive Polynomial Chaos (APCE), and Support Vector Machine Regression (SVM). The computational cost is compared with the traditional Monte-Carlo...

  In this paper, a versatile technique for mesh defor- mation is discussed, targeted at the electromagnetic (EM) field simulation of high-frequency devices using the 3-D finite element method (FEM). The approach proposed applies a linear elasticity model to compute the displacements of the internal mesh nodes in 3-D when the structure geometry is changed. The technique is compared with an alternative approach...

  Publikacja

  - Archives of Acoustics - Rok 2020

  In the early days, consumption of multimedia content related with audio signals was only possible in a stationary manner. The music player was located at home, with a necessary physical drive. An alternative way for an individual was to attend a live performance at a concert hall or host a private concert at home. To sum up, audio-visual effects were only reserved for a narrow group of recipients. Today, thanks to portable players,...

  Recently, the physically realistic protocol amplifying the randomness of Santha-Vazirani sources producing cryptographically secure random bits was proposed; however, for reasons of practical relevance, the crucial question remained open regarding whether this can be accomplished under the minimal conditions necessary for the task. Namely, is it possible to achieve randomness amplification using only two no-signaling components...

We find a Bell inequality which can amplify arbitrarily weak randomness and give a detailed analysis of the protocol involving it. Our analysis includes finding a sufficient violation of Bell inequality as a function of the initial quality of randomness....
