Utilization of light polarization when filtering the optical signal
Alexa, Jan ; Vlček, Čestmír (referee) ; Wilfert, Otakar (advisor)
This master thesis deals with the possibility of separation of useful signal from noise using polarization of laser radiation. This thesis is structured into 5 thematic units. The first unit is focused on laser radiation and its properties. The second part contains a deeper focus on the polarization of radiation, its description and the possibilities of measuring the polarization states. The third part of the thesis is devoted to the design of the measuring chains and identification of used elements. Chapter four contains measurement of status of the polarization and its results. The last chapter analyzes particular measuring chains outputs according to their spectral characteristics.

Verification of Properties of WiFi IEEE 802.11n
Alexa, Jan ; Miloš, Jiří (referee) ; Kuder, Zenon (advisor)
This bachelor thesis is focused on introducing with WiFi standard – IEEE 802.11 in general. A deeper focus is devoted to modern standards 'n' and 'c', showing the main differences and innovation compared to older standards 'b', 'g', 'a'. Furthermore, this work focuses on the use of MIMO technology. The last part is devoted to the design of laboratory tasks for teaching at the undergraduate level, which demonstrates the use of MIMO technology. Part of this thesis is an application that demonstrates the differences between those standards.

Verification of Properties of WiFi IEEE 802.11n
Alexa, Jan ; Miloš, Jiří (referee) ; Kuder, Zenon (advisor)
This bachelor thesis deals with wireless systems of IEEE 802.11 standards. This thesis explains the fundamental terms and principles, which are relating to digital wireless systems. This thesis is structured into four thematic units. The first chapter discusses an introducing with Wi-Fi standard – IEEE 802.11 in general. Second part contains a deeper focus on modern standards 'n' and 'ac', showing the main differences and innovation compared to older standards 'b', 'g', 'a'. Further in this part of the thesis is described using of MIMO technology. The third chapter contains an analysis and description of the application, which is part of the thesis. The fourth part is detailed focused on to the design of laboratory tasks for teaching at the undergraduate level, which demonstrates the use of MIMO technology.

Demographic Security of Developed Countries
Alexa, Jan ; Střítecký, Vít (advisor) ; Plechanovová, Běla (referee)
The thesis offers comprehensive systemic view on the problem of demographic security. The main objective is to create framework enabling the risk assessment of population composition and demographic changes of developed countries. The key variables are identified step by step in the thesis, their relations are drafted out and the methods of operationalization suggested. Keywords: demography, security, policymaking

Reimbursement Decree and DRG mechanism and their influence on acute in-patient care
Alexa, Jan ; Zdenek, Michal (advisor) ; Bryndová, Lucie (referee)
Reimbursement Decree and DRG mechanism and their influence on acute in-patient care Abstract The thesis focuses on Czech reimbursement mechanisms and their influence on volume of healthcare provided. The main Czech reimbursement legal documents are presented and formalized and their influence on volume of provided care tested. The thesis also offers a discussion of possible ineffectiveness which may be caused by the reimbursement decree for 2012. Keywords: healthcare, DRG, reimbursement mechanism
