Firesport stopwatch
Drška, Jan ; Drexler, Petr (referee) ; Dušek, Jan (advisor)
The goal of the bachelor thesis is to design, construct and test a timer for fire sport including a large display and automatic targets. The thesis includes a market research around commercially available timing devices, their comparison with each other according to available parameters, and finally a system is designed and constructed that combines the capabilities of already manufactured sets with new features and possibilities for large-scale extension beyond the boundaries of fire sport.

Draft solution of unified industrial communication system (ICS) for the foundry object
Dušek, Jakub ; Jordán, Vilém (referee) ; Sedlák, Petr (advisor)
This bachelor thesis deals with the design of a complex network infrastructure for the Brno foundry, which is supposed to replace the inadequate infrastructure within the foundry. In the second part of the thesis are explained the concepts of computer network, network topology, Ethernet, section of cabling system and basic concepts needed to understand network infrastructure design. The third part deals with the analysis of the current situation and sets out recommendations for a new network infrastructure. The last part deals with the complex design of the network infrastructure in the foundry premises.

Design and implementation of control applications capable to connect laboratory MES system
Dušek, Jakub ; Pásek, Jan (referee) ; Kaczmarczyk, Václav (advisor)
The goal of this bachelor thesis is to understand the ISA-95 standard and the manufacturing executing system (MES) based on this standard. Control application of discrete manufacturing controlling for PLC is then created and applied on a school device model. The thesis explains the ISA-95 standard and its influence on MES. The division and functions of MES according to ISA-95 are further described and explained. The theoretical part, the application of discrete manufacturing controlling for PLC is implemented on a drill model, simulating a segment of drilling. Structure of the software has been implemented in a way to correspond to the requirements given by MES and to be easily built upon.

Reactive sputtering Al2O3
Dušek, Jan ; Boušek, Jaroslav (referee) ; Fořt, Tomáš (advisor)
Diploma thesis describes technology of pulse reactive magnetron sputtering of Al2O3 coating. Furthermore it deals with design of deposition process and testing new aluminium target. The technological window was determined by tests. As a result, it was possible to create Al2O3 coatings in the widest possible working range. The coatings created by apparatus PLS 160 were tested for optical properties in order to obtain transmittance. Besides the optical tests, the evaluation of mechanical properties and adhesion were performed. The obtained results from measurement were evaluated. Based on the results, some possible applications of the coating were suggested.

Measuring system for recording and displaying LF magnetic field
Dušek, Jiří ; Soukup, Ladislav (referee) ; Vyroubal, Petr (advisor)
Diploma thesis describes types and measuring principes of magnetic field as first. Furthermore it deals with parameters of sensor HMC2003 and data acquision. Selected card for acquision was USB-6218 from company National Instruments. After that project describes programing interface LabVIEW, which was used for desing of acquision program. Next part deals with comuncation between card and computer, drivers and properties of card. After that were explained requirements on measuring interface. Furthermore it deals with basic parts of the acquision software and describes its function with connection to user interface. Finally the interface was tested.

Penetration testing of ANC
Dušek, Jakub ; Jakub,, Přibyl (referee) ; Sedlák, Petr (advisor)
This diploma thesis deals with the evaluation of a security solution that was recently deployed by a British company renting office space. This validation system is based on a database of MAC addresses, a database of clients and active filtering of connected devices. The first part explains the concepts of computer network, VLAN and basic concepts needed to understand the function of dynamic assignment of VLAN and IP addresses. The second part is devoted to measurements based on hypotheses, according to which measures are proposed in the last part to solve these security problems.
