Production and grinding/sharpening of cemented carbide tools
Prokeš, David ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis concerns the description of rotary tools made of cemented carbides. Ce-mented carbides appear as wide range tool material with reference to ductility, hardness of material and relatively low cost. New knowledge of cemented carbide manufacturing has still improved mechanical characteristics of this material. Tools made of cemented carbides are made on modern 5 axis CNC tool-making grinder machines which can be easily set with grinding parameters and interaction with measuring tools for quick parameters changeover. All of these qualities are suitable for serial and also piece tools production.

Tribotechnická diagnostika prvonáplní motorového oleje z motorů osobních automobilů
Prokeš, David
The master thesis Tribotechnical diagnostics of first-fill engine oil from passenger car engines deals with the composition, production, distribution, wear and tear, specification of passenger car engine oils and their diagnostics and evaluation during use and wear. The research part of the thesis deals with the classification of lubricants and their brief description, classification of engine oils and a brief description of their manufacture. Subsequently, the basic concepts related to the above topic are described. The experimental part of the thesis deals with the methodology, material and actual measurement of selected parameters for the assessment of engine oil condition during engine break-in of new passenger cars. The selected indicators are the amount and morphology of particles, determination of the water content of engine oil, alkaline reserve, oxidation and additive content. The following diagnosis of the condition of the primary engine oil confirmed the assumption of a higher content of wear metals. An interesting result was the detection of higher oxidation rates in engine oils, which may be a consequence of long storage periods before the car is sold.

Disaster Recovery plan for healthcare organisation
Prokeš, David ; Potančok, Martin (advisor) ; Bruckner, Tomáš (referee)
Theme of this thesis is Disaster Recovery and Business Continuity Planning. Main goal is design of Disaster Recovery plan for specific healthcare organization. One part of the design is analysis of analyzed hospital and identification of core applications and weak spots of the system. Within the analysis is risk assessment and assessment of its impact on the main applications. Based on this research the Disaster Recovery Plan is proposed. First part defines basic parts of Business Continuity Management and process of creating plans of recovery, including theoretical description of all steps necessary to implement these plans. Second part contains analysis of examined hospital with all the steps defined in previous chapters and definition of Disaster Recovery plan, which is main output of this work. Partial goal of this thesis includes proposal of implementation of Disaster Recovery plan and final assessment of analysis and its outputs
