Influence of Climatic Factor for Landslides Formation
Olejár, Filip ; Novotný, Jan (advisor) ; Kudrna, Zdeněk (referee)
TITLE INFLUENCE OF CLIMATIC FACTOR FOR LANDSLIDES FORMATION ABSTRACT Slope movements are divided into several groups, either by speed, method of movement or by factors causing their formation. The climate conditions of different territories are one of the main reasons that significantly affect the formation of slope movements. The most important climate factor that causes slope movements is precipitation. However, the effect of freezing soil can also be included here because water in the soil changes its volume and after thawing changing geomechanical properties of the material. In this work, the impact of precipitation will be discussed as the most significant climatic factor that induces breaking of the slopes. Rainwater can either gradually infiltrate into the slope, or can infiltrate in the single event with a high amount of rainfall, until it reaches a critical stage during which the weight of watered zone together with pore pressure are being increased whereas the effective shear strength is being reduced. This causes subsequent disintegration of the slope and movement of material along the slip surface in case of sliding movements and along the native surface in case of debris flows. This work summarizes the available knowledge about the precipitation as a significant factor which affects the...

Stability of volcanic islands in relation to giant landslides on the example of El Hierro island, Canary Islands
Olejár, Filip ; Blahůt, Jan (advisor) ; Novotná, Ivona (referee)
Title: Stability of volcanic islands in relation to giant landslides on the example of El Hierro Island, Canary Islands Volcanic islands are known by common occurrence of volcano collapses usually connected with their early stage of formation. When this type of slope deformation occurs, large masses of material, often exceeding hundreds of thousands of cubic meters of rocks, are moving downslope. The development of this kind of movements is firmly linked with the period of volcanic islands growth. Nowadays, slope movements of such dimensions could have catastrophic consequences on inhabited islands. Additionally, in several cases there has been proved emergence of tsunami waves with far-reaching impacts because of these movements. Tsunami hazards have been one of the impulses to examine the probability of these slope movements' developments in today's conditions. In this work, the author tries to prove the impact of seismic activity and rapid changes of ocean water level on the slope stability model of San Andrés giant landslide on the El Hierro Island, Canary Islands archipelago. The geotechnical model parameters were obtained from laboratory analysis of rock material from the island. Then, slope stability models on San Andrés giant landslide were prepared using different combinations of input...

Simulation of the operation of the hospital department
Olejár, Filip ; Dlouhý, Martin (advisor) ; Kuncová, Martina (referee)
This diploma thesis deals with the solution to a real situation that occurred at Nemocnice Na Františku in Prague. The problem is solved by using a computer simulation in SIMUL8 simulation program. At the beginning I describe the theoretical foundations that are afterwards used as a basis for the main practical part. The main subject of the work is a simulation of an operation of the hospital outpatient department. The hospital management decided to change the system for handling patients operations. I have created simulation models for particular workday and weekend means of patients serving operations. The created simulation models and their outputs are evaluated in the final part of the thesis and will serve as a basis for making reorganization decisions in the hospital. The provided advice for hospital management fulfills the goal of this thesis.

Stock models and their solution in MS Excel
Olejár, Filip ; Kořenář, Václav (advisor) ; Flusserová, Lenka (referee)
The goal of my thesis was to analize special stock models and to create a small aplication in MS Excel. Introduction is devoted to common description of stocks. The main part is focused on special stock models especialy on quantity rabate and model Q system. Application in MS excel is created for this models. In conclusion I verified application on fictive datas.
