Distribution of grease in rolling bearing
Hynek, Jakub ; Čermák, Jan (referee) ; Šperka, Petr (advisor)
The work deals with the issue of grease distribution in a rolling bearing. Grease lubricated ball bearing in this way often experience the problem of starvation, when the contact area is not sufficiently supplied with lubricant, which leads to bearing failure. In general, this is a very complex and comprehensive topic. Specifically, the description of the effect of selected parameters on the distribution of grease in the rolling bearing was solved. The evaluation took place on the contact surfaces of the inner and outer ring and bearing balls. The average film thickness in selected areas at the point of contact and in front of it were evaluated. The method for observation was fluorescence microscopy. The effects of the percentage filling of the bearing with grease, the speed, the material and the design of the cage on the distribution and distribution of the grease on the bearing surfaces are described in the thesis. The result is information about the distribution of the grease on the raceways and balls of the bearing and their immediate surroundings. It was shown that the new experimental approach used makes it possible to evaluate the amount of grease available for bearing lubrication in a real configuration.

Modern trends in logistics of shipments
VAŠÍČEK, Jakub
Progress is unstoppable and naturally also affects the field of logistics. One of the current trends is online shopping, which is closely linked to the delivery of goods to consumers. This bachelor's thesis defines modern trends in the logistics of unit shipments, primarily in terms of e-commerce on the domestic and foreign markets. The work uses a questionnaire survey both for target consumers and for operators of online stores. It also includes a controlled interview with the operator of the parcelshop. Thanks to the understanding of the issue of parcel delivery and obtaining data and information using the above-mentioned methods, at the end of the work it was possible to propose a solution for logistics practice that would help eliminate the shortcomings of current trends in the delivery of parcels.

Essays on Data-driven, Non-parametric Modelling of Time-series
Hanus, Luboš ; Vácha, Lukáš (advisor) ; Witzany, Jiří (referee) ; Ellington, Michael (referee) ; Trimborn, Simon (referee)
This thesis consists of four contributions to the literature on data-driven and non-parametric modelling of time series. In the first paper, we study the synchronisation of business cycles and propose a multivariate co-movement measure based on time-frequency cohesion. We suggest that economic inte- gration may lead to increased co-movement of business cycles, which may reflect the benefits of convergence and coordination of economic policies. The second paper presents a new methodology for identifying persistence in macroeconomic variables. Using time-varying frequency response func- tions, we identify heterogeneous persistence effects in US macroeconomic variables. The third and fourth papers propose data-driven techniques for probabilistic forecasting of time series using deep learning. We introduce a multi-output neural network that selects the most appropriate distribution for the data. The distributional neural network is valuable for modelling data with non-linear, non-Gaussian and asymmetric structures. The third paper demonstrates the usefulness of the method by estimating information-rich macroeconomic fan charts and distributional forecasts of asset returns. In the last paper, we present the distributional neural network to obtain the proba- bility distribution of electricity price...

Distributed Processing of IP flow Data
Krobot, Pavel ; Kořenek, Jan (referee) ; Žádník, Martin (advisor)
This thesis deals with the subject of distributed processing of IP flow. Main goal is to provide an implementation of a software collector which allows storing and processing huge amount of a network data in particular. There was studied an open-source implementation of a framework for the distributed processing of large data sets called Hadoop, which is based on MapReduce paradigm. There were made some experiments with this system which provided the comparison with the current systems and shown weaknesses of this framework. Based on this knowledge there was created a specification and scheme for an extension of current software collector within this work. In terms of the created scheme there was created an implementation of query framework for formed collector, which is considered as most critical in the field of distributed processing of IP flow data. Results of experiments with created implementation show significant performance growth and ability of linear scalability with some types of queries.
