Let There Be Light? Impact of Light Pollution on the Environment
Svoboda, Lukáš ; Mihai, Hana (referee) ; Ellederová, Eva (advisor)
Světelné znečištění patří mezi mnoho druhů znečištění, které ohrožují naši planetu. Důvod jeho vzniku je vedlejší efekt průmyslové civilizace a jeho negativní dopad ohrožuje lidské zdraví, zvěř, rostlinstvo a klima. Cílem této bakalářské práce je vymezit koncept světelného znečištění, popsat způsoby měření a negativní dopady. Teoretická část bakalářské práce se zabývá definováním pojmu světelného znečištění a popisuje způsoby, jakými se světelné znečištění projevuje. Dále řeší možnosti měření světelného znečištění, a také diskutuje negativními dopady na lidské zdraví, přírodu, ekonomiku, bezpečnost a astronomii. Navazující kapitola popisuje parametry běžně užívaných světelných zdrojů pro veřejné osvětlení, a nakonec jsou probírány základní praktiky, které napomáhají snížit světelné znečištění a jsou doplněny příklady správně navrženými svítidly pro venkovní osvětlení. Praktická část této bakalářské práce se zabývá kvantitativním výzkumem, který měl za cíl objasnit úroveň povědomí o světelném znečištění mezi širokou veřejností. Data pro tento výzkum byla shromážděna pomocí dotazníkového šetření.

Detekce osob v obraze pomocí Raspberry Pi
Svoboda, Lukáš ; Appel, Martin (referee) ; Matějásko, Michal (advisor)
This thesis describes the detection of people in the image using camera devices with focus on using a Raspberry Pi minicomputer. There were created algorithms processing image data and containing algorithms, which are able to distiguish whether it is incoming or outcoming person. Another role of these softwares is to send data to the ThingSpeak platform, where charts are made from the data. The detectors of people are based on Optical flow and ACF - Aggregate Channel features methods. All software was created in the development environment MATLAB/Simulink.

Local flood early warning system
Svoboda, Luděk ; Špaček, Jiří (referee) ; Růžek, Václav (advisor)
The aim of this Master's thesis is to design a local flood warning system. The system consists of two basic types of units. The first unit is placed in the field usingsensors and evaluates the presence of water in an otherwise dry area. In the event of flooding sends a warning message using wireless technology. The second unit evaluates the warning messages and informs the personabout the situation via text messaging. Outdoor equipment is fullyautonomous and permanently placed in an outdoor environment. The system is designed based 8-bit microcontrollers. The main parametersinclude low power devices, mechanical durability and reliability.

Development of autonomous fotovoltaic system
Svoboda, Luboš ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
The project considers realization system, which will allow us to test six different operation modes on lifetime accumulators. The system will link to computer, which will execute measurement current and tension and switch betwencharging and discharging modes. The measured values will record in someone time intervals in to computer memory. After someone time will analise these measured valuer and will provide optional operation mode.

Braking marks creation analysis in dependence of vehicle deceleration
Svoboda, Lukáš ; Panáček, Vladimír (referee) ; Vémola, Aleš (advisor)
The work is divided into two parts – theoretical and practical. The first, theoretical part is focused on introduction with the problematics, describing the concept of translation motion and brake physics, defining terms adhesion and friction, skid, driving resistances, calculation formulas etc. After the mechanics chapter follows the chapter about tire and its composition and properties, and a brake system chapter, describing Anti-lock brake system (ABS) and some other important brake-support systems. Second part of this thesis is focused on practical side, which contains acceleration measuring and skid marks creation, followed by evaluation of measured data in form of calculations and graphs.
