Návrh vybraných strojně technologických zařízení ČOV se zaměřením na zlepšení hydraulických účinností / Design of Selected Parts of Machinery in WWTP focused on Improving Hydraulic Efficiency

Zejda, Vojtěch January 2020 (has links)
The wastewater treatment process is one of the most important processes which contributes to the protection of the environment. This process can also potentially recover necessary and scarce raw materials, such as phosphorus. Research of the wastewater treatment technology is an increasingly relevant topic and more innovative knowledge should be gradually implemented into existing plants. However, the implementation of such technology involves increased investment and often operating costs. This is, why there is a growing interest in improving the energy intensity and hydraulic efficiency of the installed wastewater plant machinery. The optimization of operating parameters in such machinery can also bring significant savings, which can be potentially re-invested into other technologies. This work deals with the issue of proper evaluation of installed machinery for the selection of operating parameters and assessment of their significance. As the challenge, wastewater treatment technology is very sensitive towards the combination of technological equipment and incorrect operational parameters can lead to erroneous evaluation of the efficiency of individual equipment or inappropriate engineering proposals. To eliminate these risks, an analytical procedure for the selection and evaluation of parameters is proposed in this work. This procedure is demonstrated on six types of equipment. To verify the conclusions of the proposed procedure, a model design of the equipment was performed, in which the influence of individual parameters was concisely assessed. By using the data, the proposed procedure could be validated more specifically. In this work, the necessary data for the design was obtained by experimental research and extensive testing. The results confirm the practical applicability of the proposed procedure.

Metodika návrhu optimálního způsobu zálohování velkých objemů dat / A guide to designing optimal method of backup for big volumes of data

Bartoňová, Veronika January 2012 (has links)
This diploma thesis deals with backup for big volumes of data. Data backup is a overlooked area of information technology and the data can be lost by trivial user error or breakdown on any components. In this thesis is discussed theory of backup - archive bit and his behavior based on various type of backup (full, incremental, differential or combination thereof), duration and frequency of backups or the point of ultimate recovery. In addition there are mentioned rotation schemes Round-Robin, GFS and Tower of Hanoi, where are described their principles and graphic diagram of rotation. In chapter Strategy of backup describes the backup strategy via choosing the right choice, taking into technical and economic parameters. Impact analysis, which is explained also in this chapter, describes the important moments in data recovery. For select the optimal strategy is necessary to consider not only the whole capacity of the backup data, but also the size of the backup window for data storage or storage location. In chapter Media storage you can acquainted with all backup media and their technical parameters that are available on the market and can be used for data backup. In section Guide methodology of large volumes of data backup is designed a backup plan with the necessary inputs for the actual implementation of the backup. The design methodology puts emphasis on regular backups and check their location. On practical demonstration is shown that the rotation scheme Tower of Hanoi are among the smallest need for backup media. A part of this thesis is also design of methodology for backup small amounts of data.

Nízkoúrovňová měření / Low level measurement

Roubal, Zdeněk January 2016 (has links)
The doctoral thesis presents methods for low-level measurements, which are exemplified by the general measurement of air ion concentration. Within the first section, the author progressively identifies certain critical effects influencing the concentration of air ions, and these effects are to be considered in evaluating the uncertainty of the measured concentrations. Thus, the thesis aims to provide a systematic description of the procedures and requirements related to low-level measurements; the proposed description then involves a discussion of the process reliability requirements, namely the factors of repeatability, elimination of errors, and definition and describability of measurement uncertainties. Such methodology facilitates, among other activities, the long-term monitoring of air ion concentration in extreme environments, including caves or spaces characterized by high temperatures and humidity. The use of common methods for determining the air ion mobility spectrum is accompanied by a number of disturbing effects, such as spurious fluctuation in the concentration of air ions in time. The experimental section of the thesis describes the testing of different configurations of the measuring device (a collecting electrode and a polarization capacitor); at this stage, we seek the most advantageous distribution of the electrostatic field in the sensor – a Gerdien tube. The systematic suppression of the influence of spurious fluctuations in air ion concentration during the measurement of saturation characteristics is carried out with the least-squares numerical method (as a supporting element), a hybrid technique to describe and evaluate the experimental model. In the second part of the thesis, the methodology of low-level measurement is complemented with procedures for the measurement of freezing potential. This latter domain, as an overall experimental approach applicable during phase changes of the sample, has hitherto not been sufficiently characterized from the metrological perspective, in an up-to-date manner; several subregions of the said domain remain somewhat obscured and deserve significantly more attention. In the given context, this thesis systematically considers a problem where comparable measurement results produced by multiple authors are not available. The measuring methodology proposed herein was utilized in applied research to facilitate the fabrication of an apparatus for the experimental measurement of freezing potential in pre-defined samples; the obtained results then lead us to conclusions with respect to the evaluation of effects that cause differences in the measured data, and the results can be further compared with those obtained by other researchers investigating the given segment of the problem.

Červenka, Martin January 2016 (has links)
Increased moisture of masonry occurs mainly in older buildings. In some cases these problems arise even in new buildings. This issue should be properly treated and process of rehabilitation of the building must be executed. Humid walls can be treated by chemical injections, which is nowadays quite extensive and widely used method. Unlike mechanical methods humid walls in the implementation of chemical grouting does not need a major redesign and thus is friendly to the construction of the object. The main objective of this thesis is to establish a methodology for testing the injection materials, which will include a selection of ideal injection gel.
