To thermodynamical analysis of important thermal cycles
Bayer, Zdeněk
On examples of gas turbine cycles the paper shows the importance of thermodynamic optima definition and deals with possibilities of their formulations. The next part introduces the fundamentals of the combined cycles theory and with help of cycles formed by three reversible processes points out their properties. The last part introduces the fundamentals and results of Nekolný´s analytical thermodynamics of advanced Rankine cycles.

New product installation simulation
Medonos, Michal ; Dlouhý, Martin (advisor) ; Kuncová, Martina (referee)
One of the products produced by Motorpal a.s. is a camshaft. Recently, the company signed a contract with Bosch company to produce new types of camshaft. The analysis of the impact of the contract on the production was made by simulation. To perform the simulation it was necessary to map the whole process. The simulation of the current state was made in the first phase. The results shew many uneffectivnesses in the process and lack of capacity of some workplaces. Some changes in the process were suggested and tested with the aid of the simulation. The best results were achieved when the single-item flow was used. In the second phase the production of a new type of camshaft was added to the simulation. Analysis of these results was divided into two parts. The new production was analysed in the first part and it was discovered that the planned capacites are very deficient. The impact of the new production on the current one was analysed in the second part. It shew that this impact is negativ, especially on the duration of production.

System for computing distribution problems LP – Lingo/Excel interface
Lhoták, Petr ; Jablonský, Josef (advisor) ; Mynařík, Petr (referee)
This thesis deals with description of several distribution problems and their solutions. Distribution problems are the most typical problems of linear programming, which solves the optimalization of transportation of materials, people or goods. For this purpose I created an application, which combines two computer systems and makes computing of these problems easier. Concretely by combining of the systems LINGO and MS Excel through Visual Basic for Applications. Further in this work you will find solved examples of transportation problem, allocation problem, assignment problem and travelling salesman problem. You will also find the description of the main procedures of LINGO system and its connection to MS Excel through VBA. Last but not least there is brought up the programming solution of the application and its visual construction.

[13:10:23] Lenka Weingartová: Website auditing and its influence on competitive strength of organizations
Bacík, Jan ; Molnár, Zdeněk (advisor) ; Drašnar, Jindřich (referee)
The main purpose of this diploma thesis is to analyse the extent to which is the use of internet websites exploited by logistic companies. After executing an audit, the determined results are evaluated and some correct solutions are proposed. The diploma thesis is divided into a theoretical and a practical section. The theoretical section is concerned with essential aspects of high-quality websites. These aspects are usability, accessibility, search engine optimization, technical design and graphical design. These were the foundations for creating an audit framework, which was then used for analysing individual websites. The practical section consists of a detailed audit of a logistic company. It also contains user testing which is based on observing randomly selected respondents. After the detailed audit, the summary of individual audits follows. The output of this thesis is an overview of the website presentation quality of the logistic companies with varying size. The main contribution of this diploma thesis is a complex survey and status comparison of the logistic companies' websites.

Optimizing online presentations according to the product features
Novák, David ; Horný, Stanislav (advisor) ; Krsek, Libor (referee)
The purpose of this thesis is to highlight the importance of graphic design and its visual effects in day-to-day life, notice new methods, justify relevant investments to advertisement as well as mention continuously rising demands made on professional graphic designers. The theoretical part of the thesis is based on the research article, which subject is the extent of consumers' product understanding of products being sold online. The research concludes that it is possible to choose the appropriate presentation format according to task complexity (product features) in terms of graphical and multimedia means of online presentation, such as static pictures with text captions, videos with or without narration and Virtual Product Experiences (VPE ). This is followed by the definitions of communication process and relevant standards related to web design, concluding with the description and interpretation of the most interesting and useful theoretical foundations. The main body is about implementing the theoretical findings in the real world business case including advertising campaign in a project having the purpose to give a real economic/business value. All the project phases are described from finding the business partner to the launch of brand new web service and its propagation. The new web page and other propagation materials were made in order to attract selected companies.

Optimalization of flights and revisions on ČSA airplanes
Pourová, Alžběta ; Jablonský, Josef (advisor) ; Zouhar, Jan (referee)
Flights and revisions planning is the problem of assigning flights and revisions to aircrafts in such a way that constraints are satisfied, and some objective function is optimized. Objective function can be to minimalize the number of aircrafts. The intention of my thesis is to find the optimum solution in the problem of flights and revisions planning to aircrafts. In this work, I am using linear programming, which is important and irreplaceable in everyday practical use.
