Design and Implementation of Database Application for a Manufacturing Company

Hlavním tématem této práce je navržení a implementace databázové aplikace pro správu firemních dat menší firmy. Diskutována byla řada přístupů, z nichž bylo následně vybráno vhodné řešení. Takové řešení je založeno na platformě Microsoft Access s podporou jazyka Visual Basic for Applications. Implementace splňuje všechny požadavky a poskytuje plně funkční databázovou aplikaci, která bude primárně určena vedoucímu firmy. Hlavním přínosem práce je pak zefektivnění vnitřních firemních procesů.The main topic of this thesis is the design and implementation of a database application for data management of a small-sized company. Various approaches have been reviewed and subsequently an appropriate solution has been selected. The solution is based on Microsoft Access with a support of Visual Basic for Applications. The implementation satisfies all of requirements and provides a fully functional database application, which is going to be used primarily by the manager of the company. The most significant outcome of the thesis is an increased effectiveness of the internal business processes of the company.155 - Katedra aplikované informatikyvýborn

Mimetic Concept in Discussions about Representation in Literary Theory

Diplomová práce je zaměřená na koncept mimesis a s ním spojeným pojmem skutečnosti. Cílem práce je posoudit zda je mimesis stále funkčním konceptem, nebo zda je již překonaný. Stěžejní část práce je věnována analýze vybraných konceptů mimesis, a to antických a současných, a konceptů kriticky se vymezujících vůči mimesis. Z kritického zhodnocení konceptů bude vyvozena určité podmínky, za kterých je možné mimetický koncept zachovat. Práce se rovněž zaměří i na problematičnost pojmu skutečnosti a na tomto základě koncipuje tři základní přístupy ke skutečnosti. Závěrem se zaměří na nedostatečnost definic pojmu skutečnosti a navrhne exemplární možnost pro definování skutečnosti.Obhájeno683/5000 The diploma thesis is focused on the concept of mimesis and the associated concept of reality. The aim of this work is to assess whether mimesis is still a functional concept or whether it is already obsolete. The main part of the work is devoted to the analysis of selected concepts of mimesis, namely ancient and contemporary, and concepts critical of mimesis. From the critical evaluation of the concepts, certain conditions will be deduced under which the mimetic concept can be preserved. The work will also focus on the problematic concept of reality and on this basis conceives three basic approaches to reality. Finally, it focuses on the inadequacy of definitions of the concept of reality and suggests an exemplary option for defining reality

Real-Time Model-Free Minimum-Seeking Autotuning Method for Unmanned Aerial Vehicle Controllers Based on Fibonacci-Search Algorithm

The paper presents a novel autotuning approach for finding locally-best parameters of controllers on board of unmanned aerial vehicles (UAVs). The controller tuning is performed fully autonomously during flight on the basis of predefined ranges of controller parameters. Required controller properties may be simply interpreted by a cost function, which is involved in the optimization process. For example, the sum of absolute values of the tracking error samples or performance indices, including weighed functions of control signal samples, can be penalized to achieve very precise position control, if required. The proposed method relies on an optimization procedure using Fibonacci-search technique fitted into bootstrap sequences, enabling one to obtain a global minimizer for a unimodal cost function. The approach is characterized by low computational complexity and does not require any UAV dynamics model (just periodical measurements from basic onboard sensors) to obtain proper tuning of a controller. In addition to the theoretical background of the method, an experimental verification in real-world outdoor conditions is provided. The experiments have demonstrated a high robustness of the method to in-environment disturbances, such as wind, and its easy deployability

In-orbit commissioning of Czech nanosatellite VZLUSAT-1 for the QB50 mission with a demonstrator of a miniaturised lobster-eye X-ray telescope and radiation shielding composite materials

This paper presents the results of in-orbit commissioning of the first Czech technological CubeSat satellite of VZLUSAT-1. The 2U nanosatellite was designed and built during the 2013 to 2016 period. It was successfully launched into Low Earth Orbit of 505km altitude on June 23, 2017 as part of international mission QB50 onboard a PSLV C38 launch vehicle. The satellite was developed in the Czech Republic by the Czech Aerospace Research Centre, in cooperation with Czech industrial partners and universities. The nanosatellite has three main payloads. The housing is made of a composite material which serves as a structural and radiation shielding material. Anovel miniaturized X-Ray telescope with lobster-eye optics and an embedded Timepix detector represents the CubeSat's scientific payload. The telescope has a wide field of view. VZLUSAT-1 also carries the FIPEX scientific instrument as part of the QB50 mission for measuring the molecular and atomic oxygen concentration in the upper atmosphere
