Laser subtitles projector

Obsahem této práce je návrh a realizace HW doplněného o SW pro zařízení na projekci titulků do filmu, který se promítá z promítacího zařízení na 16mm film, synchronizace titulků s filmem, zároveň práce také řeší princip problematiku změny vzdálenosti plátna. Titulky se načítají pomocí slotu pro SD kartu, ovládání probíhá pomocí ovládacího prvku, kde je použit grafický monochromní displej tlačítek, který slouží také pro nastavení celého zařízení a jeho úpravy.The content of this work is the design and implementation of HW supported by SW for viewing subtitles into the movie, which translates from the projection equipment on 16 mm film, synchronizing subtitles with the movie, at the same time the work also addresses the issues of principle changes the distance of the canvas. Subtitles are loaded by using the SD card slot control by using the control, which is used to display graphics monochrome buttons that are also used for setting the device and its modifications.

Synthesis, structure, and opto-electronic properties of organic-based nanoscale heterojunctions

Enormous research effort has been put into optimizing organic-based opto-electronic systems for efficient generation of free charge carriers. This optimization is mainly due to typically high dissociation energy (0.1-1 eV) and short diffusion length (10 nm) of excitons in organic materials. Inherently, interplay of microscopic structural, chemical, and opto-electronic properties plays crucial role. We show that employing and combining advanced scanning probe techniques can provide us significant insight into the correlation of these properties. By adjusting parameters of contact- and tapping-mode atomic force microscopy (AFM), we perform morphologic and mechanical characterizations (nanoshaving) of organic layers, measure their electrical conductivity by current-sensing AFM, and deduce work functions and surface photovoltage (SPV) effects by Kelvin force microscopy using high spatial resolution. These data are further correlated with local material composition detected using micro-Raman spectroscopy and with other electronic transport data. We demonstrate benefits of this multi-dimensional characterizations on (i) bulk heterojunction of fully organic composite films, indicating differences in blend quality and component segregation leading to local shunts of photovoltaic cell, and (ii) thin-film heterojunction of polypyrrole (PPy) electropolymerized on hydrogen-terminated diamond, indicating covalent bonding and transfer of charge carriers from PPy to diamond

AVONET: morphological, ecological and geographical data for all birds

Functional traits offer a rich quantitative framework for developing and testing theories in evolutionary biology, ecology and ecosystem science. However, the potential of functional traits to drive theoretical advances and refine models of global change can only be fully realised when species‐level information is complete. Here we present the AVONET dataset containing comprehensive functional trait data for all birds, including six ecological variables, 11 continuous morphological traits, and information on range size and location. Raw morphological measurements are presented from 90,020 individuals of 11,009 extant bird species sampled from 181 countries. These data are also summarised as species averages in three taxonomic formats, allowing integration with a global phylogeny, geographical range maps, IUCN Red List data and the eBird citizen science database. The AVONET dataset provides the most detailed picture of continuous trait variation for any major radiation of organisms, offering a global template for testing hypotheses and exploring the evolutionary origins, structure and functioning of biodiversity

Strukturální, optické a mechanické vlastnosti tenkých diamantových vrstev a tenkých vrstev karbidu křemíku deponovaných mikrovlnnou plasmou podpořenou chemickou plynnou depozicí s rozvodem lineární anténou za nízkého tlaku

In this work, we detail the properties of thin silicon carbide and polycrystalline diamond layers grown by microwave plasma enhanced chemical vapour deposition with linear antenna delivery. Structural, mechanical and optical properties are compared for their potential use as transparent hard coatings. Silicon carbide layers exhibit mechanical properties comparable to thin diamond layers but with a significantly higher adhesion and lower optical absorption coefficient over a wide spectral range.V tomto článku jsou studovány vlastnosti karbidu křemíku a polykrystalických diamantových vrstev deponovaných mikrovlnnou plasmou podpořenou chemickou plynnou depozicí s rozvodem lineární anténou za nízkého tlaku. Jejich strukturální, mechanické a optické vlastnosti jsou porovnány s ohledem na jejich potenciální využití v oblasti transparentních tvrdých potahů. Karbid křemíku vykazuje mechanické vlastnosti porovnatelné s tenkými diamantovými vrstvami, ale podstatně vyšší adhezi a nižší absorpční koeficient v širokém spektrálním oboru
