Water Balance Hydrological Models Method Comparison
Štolfa, Filip ; Bednář, Martin (referee) ; Marton, Daniel (advisor)
In this work, two types of lumped balance precipitation-runoff models were compiled, from which the model taken from the Sicilian regional climate model was subsequently modified and these modifications were compared with other models. The practical application was carried out in the Svratka river basin above the Vír reservoir ending in the final profile of Dalečín. The input data from this river basin were precipitation totals, average temperatures and flows in the final profile, from which the calculation was subsequently performed in a monthly step. The individual models were compiled in two variants differing in the length of the time series and the number of regression coefficients. All assembled models were subsequently calibrated using four calibration criteria, for which the effectiveness was verified during validation by one common criterion. At the end of the work, individual models and calibration criteria are compared.

System for LoRa Devices Management
Štolfa, Filip ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
The main goal of this thesis is to simplify the management of IoT devices in the LoRaWAN ecosystem and enable seamless migration between two central LoRaWAN servers. Two LoRaWAN network servers—ChirpStack and TheThingsStack—are described in this thesis. Based on user requirements for a smart city management system an application is designed and implemented that can communicate with these servers and offers users a single interface to manage devices on these servers. The device data is first stored in the application database and then synchronized with the selected LoRaWAN server using the provided application interface. The solution is implemented as a web application using the Angular application framework. The backend is implemented using the Express.js application framework and the AWS Lambda platform.
