Sensor based on a fiber optic interferometer
Rozsypal, Filip ; Dejdar, Petr (referee) ; Čučka, Milan (advisor)
This diploma thesis deals with comparsion of 2x2 and 3x3 couplers. There is also description of issue of the Michelson interferometer and its use as a sensor. This sensor is very good at detecting vibrations. Part of the work is description of simulation of Michelson interferometer with 3x3 coupler as vibration sensor and localization of vibration on optical fiber by Michelson and Mach-Zehnder interferometer.

Simulation of Mach Zehnder interferometer
Rozsypal, Filip ; Münster, Petr (referee) ; Čučka, Milan (advisor)
This bachelor thesis deals with the simulations of Mach-Zehnder and Michelson interferometer. These simulations are realized by VPIphotoncs and MatLab. The thesis also describes the optical and physical phenomena, the usage and the principle of operation of interferometers and results of measurements with validation of the basic work of both interferometers.

Uncertainty in macroeconomics : making RBC path dependent
Rozsypal, Filip ; Sojka, Milan (advisor) ; Cahlík, Tomáš (referee)
Mainstream and alternative notions of uncertainty, time and expectations in economics are discussed. Then the consequences of relaxing some of the assumptions are examined. The relevance of the methodological issues is brought up, when economic theories are employed to deal with real economic problems. It is argued that the assumptions should be realistic. In second part of this text, it is demonstrated how a mainstream neoclassical model can be enriched with more realistic assumptions in line with the previous argumentation. The model is then analyzed using impulse response functions, simulations and long run variance of generated time series. The model manifests interesting behavior, such as path dependency. The higher persistence and lower variance can be interpreted as evidence against a view that technological shocks are main sources of business cycles. Powered by TCPDF (www.tcpdf.org)

Asymmetric monetary transmission?: evidence from CEE region
Šarić, Amela ; Rozsypal, Filip (advisor) ; Geršl, Adam (referee)
This thesis investigates monetary transmission asymmetries in CEE region. The first part addresses the role of credit growth in monetary transmission in the Czech Republic. Employing Logistic Smooth Transition Vector Autoregression model over the 1998:M1-2012:M3 period, we find that high credit growth dampens the effectiveness of monetary policy. No asymmetries in relative effects of contractionary and expansionary monetary policy shocks have been documented. In the second part, we apply the variation of Panel VAR to examine the role of financial structure in monetary transmission. The analysis is conducted on a sample of eight CEE states, encompassing the 1999:Q1-2009:Q4 period. Higher credit dependence is found to enhance the interest rate pass-through. However, cross-country asymmetries vanish when the credit dependence is interacted with the measure of banking sector competition. The ultimate role of financial structure in output and price fluctuations is indeterminable.
