Modelling and Management of Project Portfolio
Skalníková, Zuzana ; Trchalík, Roman (referee) ; Květoňová, Šárka (advisor)
This thesis is dedicated to modeling and management of project portfolio. In the first part, project is specified, along with methods for its managing. Next part describes the project portfolio, its managing and aspects that affect it. Thesis continues with analysis and design of software prototype capable of managing project portfolios. Most suitable methods are selected for project analysis. Designed prototype is then implemented and solution is described in the thesis. Last part of the work is user testing, which pointed out the functionality and usability of created prototype.

Coexistence of wireless communication systems and LTE in the ISM band
Mikláš, Michal ; Kratochvíl, Tomáš (referee) ; Polák, Ladislav (advisor)
This bachelor thesis deals with a definition, description and measurement of coexistence scenarios which can occur between LTE and WLAN (technology IEEE 802.11xx) wireless communication systems in the ISM band. Based on the common radio frequency (RF) bands, used by these systems, different coexistence scenarios are defined. Appropriate measurement testbed and method are proposed to measure coexistence between LTE and WLAN systems. Functionality of the proposed measurement testbed has been proved and extensive measurement of previously defined coexistence scenarios has been done. The obtained results are evaluated in details.

Co-existence of the still used and upcoming digital terrestrial television and mobile communication services
Plaisner, Denis ; Kratochvíl, Tomáš (referee) ; Polák, Ladislav (advisor)
This work deals with exploring, measuring and evaluation of possible coexistence scenarios between terrestrial digital TV (DVB-T/HT2) and mobile wireless services (GSM, LTE), which can occur in a shared RF frequency bands The DVB-T, DVB-T2 and LTE standards are briefly described. RF band, where these systems are operated, are outlined too. . There are defined different coexistence scenarios. For the measuring, monitoring and evaluation of these scenarios, an appropriate laboratory workplace is proposed and realized. Results from the measurements show various influence of interfering mobile services on the interacted DVB-T/H system, depending on the considered coexistence scenario.

LTE-Advanced/WLAN testbed
Plaisner, Denis ; Staněk,, Miroslav (referee) ; Miloš, Jiří (advisor)
This thesis deals with the investigation and assessment of communication standards LTE-Advance and WiFi (IEEE 802.11n/ac). The EVM error parameter is examined for each standard. To work with different standards a universal workplace have been proposed (testbed). This universal workplace serves for adjusting transmitting and receiving means and for processing signals transmitted and interpreted. Matlab was chosen for this work, through which only control devices such as generators and analyzers from Rohde & Schwarz. This workplace also measures the coexistence of these standards. At the conclusion of this thesis, different coexistence scenarios were designed and evaluated through testbed results.

Tool for Projects Management Support
Vlk, Jakub ; Bartík, Vladimír (referee) ; Kreslíková, Jitka (advisor)
This thesis focuses on support tool for project management. The introduction describes the areas of knowledge management according to current standards of PMI. The focus is placed on the inputs and outputs of each process of all knowledge areas. To demonstrate all the inputs and outputs of processes in order to specify system requirements for transformation the illustrations have been attached. The following chapter investigates the system itself, the process of transformation of inputs to outputs. First of all the requirements specification is created. Requirements are focused on functionality, characteristics and expectations of users. At the selected process in the proposal, in agreement with the supervisor, three methods are selected. Transformation of inputs to output is described in these methods. The system should be designed with regard to the appropriate visualization of the outputs of these three methods. The thorough analysis of the results obtained is presented in the final chapter along with the students' personal contribution and the possible future development.

Secure and Efficient State Preservation in Ethereum-Based Smart Contract Platforms
Eršek, Martin ; Perešíni, Martin (referee) ; Homoliak, Ivan (advisor)
Táto práca prezentuje riešenie problémov s uchovaním stavu v rámci Etherea. Na základe analýzy vnútorného fungovania Etherea a prečítania relevantnej literarúry boli adresované relevantné problémy. Proof-of-concept riešenie vykazuje sľubné výsledky ako je 33% redukcia vo veľkosti dôkazov členstva, ako aj takmer 50% redukciu v priemernom čase vykonávania transakcií v porovnaní s aktuálnym prístupom. Navyše, navrhované riešenie umožňuje efektívne paralelné spracovanie transakcií s viac ako 97% šancou bezkonfliktného vykonania 8 náhodných transferov natívnej meny. Potenciálna nadväzujúca práca zahŕňa implementáciu klienta schopného paralelného spracovávania transakcií do produkčného riešenia, ktoré rozšíri aktuálne možnosti manažmentu stavu v Ethereu.

Coexistence Of LTE And WLAN In The ISM Band
Mikláš, Michal
This paper deals with definition, description and measurement of coexistence scenarios, which can occur between LTE and IEEE 802.11g wireless communication systems in the ISM 2.4 GHz band. There are defined common RF frequency bands for both systems and coexistence scenarios which can arise between them. An appropriate measurement workplace and setup is proposed to measure the interaction between LTE and IEEE 802.11g. The rightness of the proposed measurement setup is verified by experimental laboratory measurements.
