How discriminatory is the housing market in Slovakia: experimental investigation.
Sacherová, Kristína ; Pertold-Gebicka, Barbara (advisor) ; Kopečná, Vědunka (referee)
Housing discrimination is a widespread, but markedly underrated issue that is associated with diverse treatment of applicants for real estate's sale or rent based on their affiliation to some minority in society. Although there have been many experiments and studies conducted to uncover and measure the presence of discrimination mostly for African Americans in the US and Arabs in several European countries, such extensive researches for the Europe's largest ethnic minority, Roma, are lacking. This thesis presents an Internet field experiment on discrimination of Roma in the Slovak housing market which uses matched-pair method and four fictitious male applicants to request for a flat or house showing based on an online advert. In total, 396 requests were sent from email addresses with specific names signalizing ethnicity of applicants and the response rate was examined. Data shows that the applicants with Roma-sounding email addresses are 8 to 9.5% less likely to get an invitation for a showing compared to the applicants with the Slovak sounding email addresses. My analysis also suggests that the highest level of discrimination is found in the districts with median Roma contribution (specifically from 3 to 11%). Considering all my findings, it can be eventually concluded that in the Slovak housing...

What makes children feel good about their work: experimental investigation.
Janšta, Lubomír ; Matoušek, Jindřich (advisor) ; Zeynalova, Olesia (referee)
This bachelor thesis analyses how perceived meaning influences child performance, mood and enjoyment when performing work-related tasks. In laboratory settings, I manipulated the level of perceived meaning that was given for completion of an easy repetitive assignment by three different treatments. In the "Recognized" condition, each completed task was awarded with verbal recognition. The experimenter in the "Ignored" condition did not care about completed work. In the "Shredded" condition, the finished task was left not only unchecked, but it was destroyed immediately after submission. I observed a strong positive relationship between how "nice" experimenter behaved and how many tasks children finished. The same held for how good children felt. In general, even small acknowledgment mattered more than the demotivating procedure, but there were some gender-specific differences. Specifically, recognition played an important role for boys. On the contrary, destroying of completed tasks had a major negative effect on girls. These aspects significantly impacted both, performance as well as mood. Keywords Perceived meaning, Meaningful work, Futile work, Experimental investigation, Children

Hydrodynamic Behavior of Large Bubbles inSlot Channels.
Ezeji, Kingsley
We present the results of experimental investigation on the dy-namics of air bubbles rising in stagnant or co-flowing liquid insidean inclined rectangular channel. Variable channel geometry (withadjustable height𝐻, perimeter𝑃 = 2(𝐻 + 𝑊), inclination𝛼, and orien-tation – flat𝐻 < 𝑊or tall𝐻 > 𝑊) enabled us to evaluate the influenceof different operation parameters on the bubble shape and velocity. Measurements of the rise velocity of large Taylor bubbles (𝑈TB) werecarried out by using a high-speed video camera system and an imageprocessing technique.

Hydrodynamic Behavior of Large Bubbles in Slot Channels.
Ezeji, Kingsley
We present the results of experimental investigation on the dynamics of air bubbles rising in stagnant liquid inside an inclined channel. The experiments were conducted in a Plexiglas channel having a rectangular cross-section (240×20 mm). Different channel geometries were then obtained by insertion of suitable plates into this basic channel.

Numerical Simulation and Experimental Modelling of Fluid - Structure Interaction in Veins
Štembera, V. ; Chlup, Hynek ; Maršík, František
The mixed formulation of the finite element method with the separately interpolated pressure is used for the numerical simulation of the fluid structure interaction. To describe a wider class of problems we consider in the simulation the three material models: the Neo-Hookean, the isotropic Gent model and the anisotropic Gent material model to include the influence of collagen structure of blood vessels. The fluid is modelled as Newtonian liquid. The strong coupling of both structure and fluid solvers allow us to simulate large deflection oscillations of the structure. The special experimental mock up line was designed for the investigation of unsteady fluid structure phenomena. Latex tubes with variable inner diameter and wall thickness are used as specimens. The qualitative and quantitative fluid structure phenomenon investigation are performed for both the continuous and pulsatile flow.

Flow behaviour of highly concentrated slurries
Vlasák, Pavel ; Chára, Zdeněk
The paper describes results of experimental investigation of the highly concentrated fine-grained slurry. The flow behaviour of the slurry was experimentally investigated for the laminar and turbulent regimes with respect to the effect of solid concentration and flow velocity. The re-circulation pipe loop with smooth stainless steel pipe of the inner diameter D = 17.5 mm was used. Stony dust from Mistrovice quarry (d50 = 8 μm, ρs = 2 701 kg/m3) was used as a solid phase, water was used as a carrier liquid. Volumetric concentration and slurry velocity reached up to 44% and 6 m/s, respectively.

Experimentální výzkum Magnusovy síly působící na hladkou kouli při vysokých Reynoldsových číslech
Kharlamov, Alexander ; Chára, Zdeněk ; Vlasák, Pavel
The paper describes the results of experimental research dealing with rotating smooth spherical particles moving quasi-steadily in calm water. The motion of the particles was recorded by a digital video camera. The kinematics of the particles motion was analyzed numerically. The dimensionless Magnus force coefficient, the Reynolds number Re and spin parameter Γ (ratio of peripheral sphere velocity and translational velocity) were evaluated from the time series of the particle coordinates and its angle of rotation. The Magnus force was determined as a function of the Reynolds number and spin parameter for 3000 < Re < 42000 and 0.1 < Γ <7. The results were compared with results from literature and overall data were fitted by a simple function valid for 0.5 < Re < 140000 and 0.1 < Γ <10.
