Study of the ecological impact of production, operation and disposal of various types of cars
Kutnar, Václav ; Jandová, Kristýna (referee) ; Jaššo, Kamil (advisor)
To reduce greenhouse gas emissions, countries have focused on (among other things) automobile transport. However, there are different car powertrains, and each produces a different amount of emissions from different parts of their lifecycles, which also vary from state to state. Knowing exact, comparable values is necessary for deciding how to reduce these emissions most efficiently and economically possible. Existing studies often focus on only one part of the life cycle and/or are not localized to a particular state. This study analyses the entire life cycle of a vehicle and its fuel or energy for a vehicle manufactured, operated, and recycled in the Czech Republic. It draws on existing studies, supplemented by data from state agencies, vehicle manufacturers, and our calculations. It was found that in the Czech Republic, compared to a vehicle with a petrol internal combustion engine (ICEVg), an electric vehicle (BEV) has 33% lower total GHG emissions, and a vehicle with hydrogen fuel cells (FCEV) 19% lower. However, an internal combustion engine vehicle has lower emissions from its production and as a result, its cumulative emissions are lower than an electric vehicle until 70,000 km driven and a hydrogen fuel cell vehicle until 111,000 km

Software support for alarm security system design
Kutnar, Václav ; Zeman, Václav (referee) ; Burda, Karel (advisor)
Intrusion alarm systems are an important part of quality security of residential, commercial, and other types of buildings. It is necessary to sufficiently and broadly asses the object and its surroundings. This bachelor's thesis proposes a methodology that should help with this designer. The thesis first discusses the general procedure of system design, relevant standards, then the elements of mechanical security of buildings, and burglary statistics in the Czech Republic. Based on this information, a methodology is then developed and software implemented, which, based on the entered information, will provide the designer with information important for the quality design of the system. These include possible object vulnerabilities, potential intrusions, the security level of the system, and more.
