Sewage connections to the sewer network
Novotný, Jiří ; Raček, Jakub (referee) ; Hluštík, Petr (advisor)
The Bachelor thesis comprehensively focuses on the issue of sewerage connection. The first part deals with technical sewerage connections approaches according to the applicable standards and laws. Secondary the thesis describes a procedure of furnishing sewerage connections. The following part emphasizes the steps which has do be done by a builder to get a permission from the construction authority and the operator to approved the connection. The last part compares selected city standards that clearly define the rules for a construction and an operation of the sewer system in the area.

An Arrhytmia Classifiication Based on RR Interval
Novotný, Jiří ; Škutková, Helena (referee) ; Kozumplík, Jiří (advisor)
This bachelor’s thesis deals with automatic classification of cardiac rhytm based on the sequence of RR intervals. The theoretical part deals both with characteristics of arrhytmias, which have been classified and the principles of the detectors and classificators used in this thesis. In the practical part, the QRS detector based on the calculation of the envelope of the ECG signal was realized in Matlab. Furthermore, the algoritm classifying arrhytmias based on the analysis of RR intervals was created. The reliability of the detector and the efficiency of the classificator was tested on the standard database CSE. The sensitivity of the detector was 98,28% and its positive predictive value was 98,38%. The diagnoses of the implemented classificator concurred in 73,17% with the cardiologists‘ diagnoses.

Impact of Drivers' Working Regimes in Freight Road Transport on Transport Safety
Máša, Vojtěch ; Novotný, Jiří (referee) ; Libertín, Josef (advisor)
Working arrangements are restrictive limits for drivers important for both motor carriers and drivers. Have a major impact on the logistical arrangements of manufacturing companies that transport their goods by road. Failure to comply with these limits, is recently one of the major problems in road transport and leads to unfair competition between road hauliers. Carrier's failure to obtain such social legislation crucial competitive advantage. Recently the problem devoted much time from the perspective of politicians. States, violations of social legislation by the carrier and the driver severely punished and often the articles we read on the operating modes of drivers and their associated hazards of freight transport, road safety hazard, danger for drivers of cars. For 10 years devoted to the issue and participate in the creation of training materials on the subject of Logistics and. In my work I wanted to examine the issue of working arrangements drivers from professional point of view - how the limits are set and working arrangements whether they comply with road safety. Next, consider the statistics of accidents in the CR in relation to drivers' working arrangements and to propose changes that would contribute to the improvement of social legislation in relation to road safety.

Evaluation of Legislative Regulations for Special Road Transport between the Czech Republic and North Europe
Kuře, Arnošt ; Novotný, Jiří (referee) ; Kudláček, Jaroslav (advisor)
he project evaluates legislative regulations for special road transport between the Czech Republic and Northern Europe. The main purpose of the project is to formulate a basic methodology for non-standard shipment’s transit. Work observes destination of the Czech Republic - Denmark, Finland, Norway and Sweden. There exist differences in legislative conditions for the particularly heavy and oversized loads transport in these countries. The main objective is to evaluate these conditions and recommend utilization for Czech carriers. The thesis aims to enumerate the various national legal standards for excessive transportation and recommend implementation outputs for correct and a quick orientation in the rights and obligations during executing carriage for the Czech carriers. The basic metodology how to transport oversized loads results from this project.

Ways of Using Digital Tachograf Data for Authorised Experts' Work
Zeman, Petr ; Novotný, Jiří (referee) ; Libertín, Josef (advisor)
The introduction of digital tachographs has brought many changes compared to previously used analogue tachograph. Legislation addressing this issue is quite extensive and often amended. Ever-present threat of industrial equipment, which affect the observed, and the stored data has a negative impact on road safety. The aim of this paper is to present a comprehensive overview of legislation regulating the issue of digital tachographs in relation to the introduction and use of digital tachographs, with obligations to use a tachograph, tachograph functional requirements. Process further review of data on vehicle operation recorded with a digital tachograph and analyze their availability in terms of approval of the different actors (the driver, carrier, service, police, other supervisory authorities). Contribution of this work is the elaboration of recommendations for the expert's methodology in analyzing data from the digital tachograph.

Muscle noise filtering in ECG signals
Novotný, Jiří ; Kubičková, Alena (referee) ; Smital, Lukáš (advisor)
This master's thesis deals with the optimization of numerical coefficients of the Wiener filter for muscle noise filtering in ECG signals. The theoretical part deals with ECG signal characteristic and muscle interference. It also contains a summary of the wavelet transform, wavelet Wiener's filtration, methods for calculating of the threshold and thresholding. In the last theoretical part the characteristic optimization techniques, the exhausive search and Nelder-Mead simplex method are mentioned, which were implemented in the practical part of this thesis in MATLAB. The functional verification and Wiener's filter optimization were tested on the standard electrocardiograms database CSE. By using the methods of exhausive search, the initial estimate for the solution method Nelder-Mead was obtained. The optimization method Nelder-Mead gives better results in the orders of hundredths or tenths than the method of exhausive search. The practical part is finished by the comparison of results of implemented algorithm with optimum coefficients, implemented in this thesis, with the results of other methods for filtering muscle interference in ECG signals.

Analysis of possibilities to improvement induction motors efficiency
Novotný, Jiří ; Hájek, Vítězslav (referee) ; Mach, Martin (advisor)
In the first part of the master’s thesis dealing with the increasing efficiency of induction motors there are briefly presented basic information about induction motors, followed by an overview of the losses of induction motors. The next part deals with the ways to increase efficiency of induction motors without increasing tooling costs. The practical part consists of four measurements of four induction motors, with their various mechanical adjustments to make comparing benefits of these modifications possible. The measured results are compared by a finite element method in Maxwell 2D Design program, in which the same motors are simulated as measured. Theoretical knowledge about the increase of efficiency is practically applied while being implemented in the simulations.
