Biological pretreatment sewages water
Veselý, Václav ; Beňo, Zdeněk (referee) ; Pěček, Jan (advisor)
Bachelor's thesis deals with waste water purification at the stage of pre-inflow of water into the biological waste water treatment plants. It is divided into two parts, a theoretical and calculation. The theoretical part deals about sewage water and the method of biological treatment. Design proposal is part of the activation tank for quantity EO.

Connection simulation between master and end unit in passive optical networks
Moravcová, Klára ; Kočí, Lukáš (referee) ; Horváth, Tomáš (advisor)
The purpose of this bachelor’s thesis is to introduce and explain the standards of passive optical networks, their way of establishing connection between master unit and end unit in a network, as well as creating a working simulation in Matlab. The first chapter of this thesis covers the description of optical networks. In the chapter, individual layers of the GPON standard by ITU-T and the EPON standard by IEEE are described. The process of an ONU unit activation towards the OLT unit of these standards is covered in detail. The thesis describes the following standards: EPON, GPON, 10G-EPON, XGPON and NG-PON2. The practical part covers the simulations of the mentioned standards, which are displayed in the form of graphs. The results are interpreted through comparison of the graphs with various input parameters (number of connected ONU units and the length of the distribution network) with a final evaluation of these results.

Methods of treatment of urban waste water and the possibility of using treated water
Charalambous, Panagiotis ; Benešová, Libuše (advisor) ; Tonika, Jaroslav (referee)
Nowadays, wastewater treatment is becoming increasingly necessary due to the reduction of water resources, the increasing price of drinking water, as well as the shrinking underground water reserves. The treatment of wastewater for reuse and disposal is particularly important for countries and regions which suffer from drinking water shortage. Thus, it is vital to find sustainable solutions for the better protection of the environment and also to improve the water's quality by adapting new and more efficient technologies. This bachelor thesis contains a comprehensive study of different methods and technologies that are used today for the wastewater treatment, with a specific emphasis on urban wastewaters. Furthermore, it examines the post-treated wastewater management, including possible ways of reusing them in many aspects. Keywords: urban wastewater, activation process, biofilters

Gpon Attacks And Errors Classification
Tomašov, Adrián
This paper focuses on various types of attacks and errors in an activation process of Gigabitcapablepassive optical networks. The process sends messages via Physical Layer Operation Administrationand Maintenance header field inside the transmitted frame. An exemplar network communicationis captured by a special hardware-accelerated network interface card capable of processing opticalsignals from passive optical networks. The captured data is filtered of irrelevant parts and messagesand correctly formatted into a suitable shape for a neural network. The filtered data is divided intosmall sequences called time windows and analyzed using a recurrent neural network-based on Gatedrecurrent unit cells. A new neural network model is designed to classify sequences into several categories:additional message, missing message, error inside (noisy) message, and message order error.All of these categories represent a certain type of attack or error. The proposed model can distinguishmessage sequences into these categories with high accuracy resulting in revealing a possible attackeror drift from protocol recommendation.

Units Connecting to the PON
Kočí, L.
Transmission Convergence Layer represents the principal part of the standard for 10Gbit/s networks (XG-PON). There are seven conditions under which the ONUs pass through when activated. The first five conditions focus on implementing data communication. The simulation demonstrates that as the number of simultaneous connections to an ONU increase, the longer the wait time for each additional connection becomes. The speed up of the connecting ONUs has been proven.
