Centre-fed microstrip patch antenna
Jireček, Martin ; Láčík, Jaroslav (referee) ; Raida, Zbyněk (advisor)
Systems with extreme bandwidth are part of advanced modern systems at radio high capacitive communication. Originally this technology was intended for radar scan. Thanks to wide frequency band had radar possibility „ see" a behind crimp, e.g. behind woody partitions etc . To his noise immunity, fail safe tapping plus small wattage heftiness began use for datal systŽm function. If is elementary antenna compound from coaxial probe and shorting outlet, it is possible use to actuating separate narrow slot placed in the middle of incandescent dabs. Impedance and radiating characteristics conventionally plumbed phlobaphene antennae excited tape lead and suggested microstrip phlobaphene antennae are experimentally explored plus collated. Explored is so and effect changes slotted longitude slot on characteristics elementary antenna.

Flash OFDM network efficiency
Jireček, Martin ; Mikulka, Jan (referee) ; Hanus, Stanislav (advisor)
The FLASH-OFDM networks (Fast Low-latency Access with Seamless Handoff-Orthogonal Frequency-Division Multiplexing) are insert to network of fourth generations. The system are set to fast data transfer. These networks have lower latency than network of third generations. On average is transmission speed for downlink cca 1,5Mb/s and for uplink cca 300-500kb/s. In connection with progress of high-speed network and systems with finite mobility (Bluetooth, IEEE 802.11), creationed want of new standard, which connect both merits. For WiMAX was defined new basic requirements: • mobility of user, • high-speed data transfer with roaming, • the lest latency of systém using aplications in real time, • high count of at the same time communication users in cell, • chance of better control QoS (Quality of Service).

Marketing activities of project of non-profit organization Lékořice "Naše kavárna"
Šebková, Kateřina ; Procházková, Markéta (advisor) ; Jireček, Martin (referee)
This thesis deals with project "Naše kavárna"("Our café"), which was established by the non-profit organization Lékořice, as an opportunity to create job vacancies for relatives of long term hospitalized patients. The theoretical section provides insight into the marketing principles used in the service sector and above all, in hospitality. The practical section through the use of marketing research, applies the theory on the actual project, describes the current situation, and arrives with plans and recommendations on how to improve the marketing of the café.
