Abstract:

The dissertation deals with the time-domain dielectric relaxation spectroscopy of carboxymethylcellulose. The main attention was paid to the experimental part of research, mainly to the design and subsequent development of an experimental setup for the measurement of discharge currents and for their processing and analysis. The subject of the measurement is carboxymethylcellulose (CMC), which is a simple polysaccharide used in wide range of applications, among else also in biomedical engineering. The study of CMC properties has required the development of a new experimental set-up of original design, which includes the equilibration (short-circuiting) of a sample before the measurement, charging and discharging at defined time intervals, switching between these two modes, recording of measurement, adjustments and processing of measured signals up to Fourier transformation into the frequency domain and, finally, calculation of complex permittivity of the sample. The frequency dependence of complex permittivity or its imaginary part, obtained by Fourier transformation of discharge current in time domain, is then referred to as the dielectric spectrum. In view of the fact that current measurements were done at very low levels of measured signal (below 10-12 A) the whole measurement was no easy matter. The framework of the work also necessitated studies and subsequent resolution of problems associated with shielding, grounding, presence of noise and sensitivity to various ambient influences. The research work focused on a reliable and trustworthy measurement of very low discharge currents and, subsequently, mathematical processing of noise present in them, i.e., operations with the original, experimentally established signal in time domain, leading in principle to a digital filtration of measured dielectric data. A further pursued objective is the explanation of dielectric parameters of tested carboxymethylcellulose sample in the widest possible frequency spectrum. The integral part of the research was the selection and application of the method for the transformation of the adjusted signal to the frequency domain. The experimental works, including data processing, were carried out in the Department of Physics, Brno FEEC BUT. Measurements were done with Keithley 617 Electrometer, HP4284A Frequency Analyzer and Janis CCS-400-204 cryogenic system. The results were completed with results obtained at the V Department of Experimental Physics, Centre for Electronic Correlations and Magnetism, University of Augsburg, Germany.

Abstract:

The goal of this master's thesis is to design and implement a system for recognition of home appliances based on their power consumption characteristics. This system should identify the individual home appliances from measurements of the total household consumption. The acquired data could be used for statistics of usage of a particular appliance and subsequent detection of errors or non-standard behavior of the measured device. An important part of my work is a design and hardware implementation of a unit for measuring and a system for processing the measured signal. The first version of my project uses pulse output of an electrometer to measure the energy. This method does not provide a sufficient sample rate but it's a quick way to obtain data for processing and analysis. The second version monitors the power consumption with a multi-purpose AC converter which measures active and reactive power with the desired sample rate. The data is then processed and recognized by two classifiers - HMM and KNN.

Abstract:

This Master thesis deals with low-current measurement in order of picoamps up to a few tens of femtoamps. Such low currents measuring is necessary for determination of air ions concentration. Disturbances, which are otherwise negligible for ordinary measurements must be considered. For example, leakage currents and noise generated in measuring device circuit. The choice of a precise operation amplifier with low input bias current is as important as the selection of low noise passive components. The aim of the thesis is to design and implement a precise low-level amplifier for the purposes of air ions concentration measurements.

In dieser Arbeit wurde ein computergestütztes, dynamisches Ein-Spur-Modell eines Pkw mit einem parallelen hybrid-elektrischen Antrieb (P2-Topologie) in Matlab-Simulink entwickelt. Es erlaubt die Skalierung des elektrischen Leistungsanteils und simuliert die Betriebsarten elekt- risches, konventionelles und hybrides Fahren, Bremsenergierückgewinnung und Start-Stopp- Betrieb. Ferner kann durch die Modellierung einer Einscheiben-Trockenkupplung zwischen Verbrennungs- und Elektromotor die Momentenübertragung bei schlupfender Kupplung wäh- rend des Anfahrens oder beim Start des Verbrennungsmotors durch den Elektromotor nach- gebildet werden. Die Fahrzeugsimulation kann in drei verschiedenen Fahrzyklen (NEFZ, WLTP, FTP-75) durchgeführt werden. Als Ausgabegrößen stehen u.a. der Kraftstoffverbrauch, die CO2-Emissionen, die Antriebs- und Rekuperationsarbeit am Verbrennungs- bzw. Elektro- motor und an den Rädern sowie die dafür benötigte bzw. rückgeführte elektrische Energie zur Verfügung. Zusätzlich kann der zeitliche Verlauf zahlreicher relevanter Größen dargestellt wer- den. Die Validierung der Simulation zeigte eine gute Übereinstimmung mit den Daten eines realen Fahrzeuges in Bezug auf Beschleunigungsverhalten, Maximalgeschwindigkeit und Kraftstoffverbrauch
In the frame of this Master Thesis a dynamic single-track-model of a hybrid electric vehicle was developed. The model comprises basic operation modes such as electric, conventional and hybrid driving, recuperation of braking energy and engine start-stop. It allows to scale the split of the propulsion between the combustion and electric engine. A further fundamental com- ponent is the model of a friction disc clutch, enabling the simulation of torque transmission of a slipping clutch during the vehicle start and the upspeeding of the combustion engine through the electric engine. The program offers three driving cycles for simulation (NEDC, WLTC, FTP- 75). Fuel consumption, CO2-emissions, propulsion and recuperation work of the combustion engine, electric engine and the wheels are provided as output variables as well as the required and recuperated electric energy. Furthermore several relevant variables are displayed in their progress over time. The model was validated against real vehicle data showing a good corre- lation regarding acceleration, maximum speed and fuel consumption

Abstract:

The master thesis done within the master study programme Transport vehicles and handing machinery presents a design of a wood splitting machine. The first part of the thesis is a literary review focused on current state in the field of wood splitting machines and on the overview of the most common wood species including their technical parameters. In the second part of the thesis, suitable machine components were chosen for the conceptual design of the wood splitter, taking into account predefined parameters. Then a machine frame was designed and its strength was verified by analytical and FEM method. Finally, drawing documentation for the machine, machine frame and splitting tool was created.

Abstract:

The thesis describes the design of the wood-splitting machine including stress and check calculations and design of the hydraulic circuit. For structural design, it is necessary to choose the maximum dimensions of wooden logs, which have length 1,1 m and diameter 0,5 m and over. The machine structure is vertical. Another task of the thesis is a technical report of similar machines and the justification of the design concepts of splitting machine. In the thesis, there is elaborated an experiment on different types of wood splitters, stress analysis calculated by using finite element method and there is also drawn up technical parameters of wood.
