Nuclear power plant condenser design
Havel, Jaroslav ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
The submitted bachelor’s thesis deals with the design of a condenser for the new Dukovany II nuclear power plant with an electrical output of 1,200 MW. The specified condensation parameters reflect typical parameters of pressurized light-water moderated and cooled reactors of the same power and climatic conditions in the given location. From the assignment of the thesis and the research carried out, the following requirements for the designed device emerged: to ensure the condensation of steam in the secondary circuit in filmwise condensation mode, to comply with the maximum cooling water heating of 10 K, to install the tube bundle at optimum angle and to ensure the competitiveness of the product. For the selected concept with a four-body condenser, a thermal analysis was made and solved numerically by a fixed-point iteration method. The calculation was performed using the EES software. The results showed that a heat transfer surface area of 121,263.96 m is required to ensure failure-free operation of the condenser. Each condenser body consists of 31,400 titanium tubes with a cross-section of ( 22 × 0,5) mm and a length of 14,554 mm. A dimensional drawing is also attached.
Evaluation of the natural value and ecosystem services of natural biotops in the intensively managed agricultural landscape
HAVEL, Jaroslav
My thesis is focused on valuation methods intensively used agricultural landscapes according to the importance of near-natural habitats in terms of their natural values and ecosystem services. This is done at four sites using pitfall traps, where there was a catch beetles (Carabidae). To evaluate the data I used indicators such as the Shannon index serenity. Procedures for calculating the ecological value of the area and the ecosystem services provided I processed according to the proposed method Seják et al., (2010). Rating I performed by BVM (,, habitat valuation methods "). Replacement cost method I used for the calculation of ecosystem services.
Cloud technology in an environment of banks
Havel, Jaroslav ; Kubálková, Markéta (advisor) ; Koubalíková, Jitka (referee)
Bachelor's thesis deals with public cloud technologies in the banks, especially the risks associated with the use of public cloud in banking institutions. The first part is in detail analyzing the concept of cloud computing and explaining the key characteristics of this technology. The next chapter defines the concept of a bank and there is a listing of the most important regulatory requirements in relation to outsourcing, by extension cloud computing. In the last two chapters are the threats arising from the use of public cloud services correlated with regulatory and legal requirements that banks must comply. Then there is the table of risks that every financial institution should consider when they intend to use public cloud technologies.
Use self-propelled sprinkles in agricultural primary production business.
HAVEL, Jaroslav
My bachelor´s work is pointed to the sprinklers, type Rogator 418 and type Samec 2. These sprinklers are in the ownership of AGRO Radomyšl, where I could use all financial and technical figures from. The company AGRO Radomyšl is busy in the sphere of agricultural plant protection. It serves as to small farmers, as well as to big agricultural companies. I could compare the running costs in four years. I was concentrated to the costs of every sprinkler, up to its type. The technical figures of every sprinkler I entered into the transparent tables. Thanks to observed parametres, I obtained general knowledge of every sprinkler up to its costs.
