Performance of the system for energy utilization from biomass
Koláček, Richard ; Máša, Vítězslav (referee) ; Pavlas, Martin (advisor)
This diploma thesis deals with the problems associated with acquisition of experimental data from technological unit for biomass combustion with nominal capacity of 1 MW, with regard to determination of thermal efficiency. In the introduction part, parameters of currently available biomass-based fuels as well as of those with large potential in the future are summarized. Further, a review in the field of biomass combustion technology is given. Biomass boilers are compared according to their technical parameters, function and benefits and drawbacks. In theoretical part methods for determination of thermal efficiency by direct method, indirect method and modified indirect method are described. Main parameters influencing resultant values of efficiency are included into the analysis. In final part an evaluation of real operational data from prototype unit combusting wooden chips is made. Recommendations for further experimental data gathering and their processing with the aim to evaluate thermal efficiency are suggested.

Software for Communication and Configuration of JSD600 Data Collection Unit
Pajgrt, Michal ; Kreslíková, Jitka (referee) ; Kotásek, Zdeněk (advisor)
This diploma thesis describes a JSD600 unit intended for mathematical processing, measuring and data recording. The JSD600 unit is highly intended for industrial measuring of water steam energy delivery.First part of the work focuses on basics of the JSD600 unit detailing and describing main structures and principles for relevant data storing.Next part summarizes some basic facts and knowledge from the area of industrial liquid flow, energy measuring and describes water steam states. All these points within this range are needed for dilemma understanding.Last task deals with complete list of communication datagrams, which have been used for communication with JSD600 unit, including a main packet of structure descriptions.The second part of this dissertation brings the unit setup application description including some implementation details of the most interesting parts.

Polynomial Equations Roots
Tomšík, Filip ; Kopřiva, Jan (referee) ; Kunovský, Jiří (advisor)
Bachelor´s thesis purpose was been study solution algebraic and differential equation. We were studying Bairstow method, which is the most conducive to solution homogenous differential equation higher order. Implementation Bairstow method and her connection with Gauss elimination method. In the end we are performed tests on rate calculation and accuracy.

Methodology Comparison of the Statement of Cash Flows as Regulated by Czech Accounting Legislation, IFRS and US GAAP
Přibáňová, Aneta ; Zelenková, Marie (advisor) ; Vašek, Libor (referee)
This masters thesis main focus is a statement of cash flows as regulated by czech accounting legislation, International Financial Reporting Standards and US GAAP. First chapter describes the importance of Statement of cash flows and his value added for users of financial statements. The historical context of the statement is shown, it is stated which entities are obligated to report statement of cash flows and lastly the internal structure of the statement is discussed. The second chapter begins by general methods of preparing the statement, then so called specific items are dealt with. The solution of some advanced accounting transactions (government grants, leases, loans, deferred payments etc.) is described. In the end the presentation and dislocure requirements are discussed. Last chapter contains research, where 99 companies are researched, answers are made concerning stated research questions and research hypothesis are concluded.

Cash flow statement in Czech republic
Kreslová, Pavlína ; Randáková, Monika (advisor) ; Zelenková, Marie (referee)
The bachelor thesis deals with the cash flow statement in Czech republic. The thesis is divided into two parts, theoretical and practical. Theoretical part follows up the components of financial statements especially the cash flow statement. Next chapters observes the structure of the statement and methods of constructing the statement which are explained on simple illustrations. Practical part analysis the cash flow statements of chosen enterprises in Czech republic.
