Geometry of Linear Model
Línek, Vítězslav ; Hykšová, Magdalena (advisor)
The advantage of the geometric approach to linear model and its applications is known to many authors. In spite of that, it still remains to be rather unpopular in teaching statistics around the world and is almost missing in the Czech Republic. In this work, we use geometry of multidimensional vector spaces to derive some well-known properties of the linear model and to explain some of the most familiar statistical methods to show usefulness of this approach, also known as "free-coordinate". Besides, historical background including selected results of R. A. Fisher is briefly discussed; it follows that the geometry approach to linear model is justifiable from the historical point of view, too. Powered by TCPDF (www.tcpdf.org)

Nursing case report of a patient with diagnosis stroke
Rusnáková, Tereza ; Línek, Vladimír (referee) ; Horová, Hana (advisor)
The theme of this bachelor thesis is "A nursing case report of a female patient with the diagnosis of stroke." The thesis is divided into clinical and actual nursing-care parts. The clinical part is subdivided into chapters, in which I first described the characteristics of the disease, basic identification of the patient, overview of patient history and other diagnoses. In the end I focused on the description of therapeutic care and a brief summary of the hospitalization. In the nursing-care part, I described the nursing history, futher on is the definition of the nursing diagnosis, the plans of nursing-care and their realization and evaluation. The aim of this thesis was to describe the problematics of stroke and elaborate a nursing case report regarding the biological and psycho-social needs of the patient. Key words:

Gas Hold-up and Volumetric Mass Transfer Coefficient of Various Impeller Types in Gas-Liquid Dispersion with Higher Viscosity
Zedníková, Mária ; Linek, V. ; Moucha, T.
In a vessel with inner diameter 0.29 m supplied by one, two or three impellers on a common shaft, there were measured transport characteristics (gas hold-up and volumetric mass transfer coefficient) in dependence on power consumption. As an impeller there was used the pitched blade impeller pumping the liquid either upwards or downwards. Air was used as a gas phase and 3% solution of Sokrat 44 as a liquid phase. The solution behaves as a newton liquid with viscosity 12.9mPa.s. Volumetric mass transfer coefficient was measured by dynamic pressure method. Gas hold-up and kLa were presented in dependence on power consumption and on gas superficial velocity. Results are compared with the data of given impeller types obtained in low viscous solutions and with the data of other impeller types.

Transportní charakteristiky různých vícemíchadlových konfigurací v míchané disperzi kapalina-plyn s vyšší viskositou
Moucha, T. ; Zedníková, Mária ; Linek, V.
Mixing intensity, gas hold-up and volumetric mass transfer coefficient of various multiple-impeller configurations are measured in a vessel of inner diameter 0.29 m equipped with three impellers on a common shaft. Five types of impellers are used. Distilled water with 3 vol.% Sokrat 44 is used as a liquid phase with Newtonian behaviour and viscosity 12.9 mPa.s. Air is used as gas phase. Mixing intensity was measured using tracer experiment and Dynamic Pressure Method was used for the measurement of volumetric mass transfer coefficient. Transport characteristics are presented for individual impeller configurations as functions of power consumption and superficial gas velocity. The impellers are compared each other and with transport characteristics for non-viscous solutions measured previously.
