Analýza výstupních parametrů souprav na zpracování půdy
Němec, Lukáš
The thesis introduces and briefly describes an overview of tillage's technologies which are applied in modern agricultural operations. These are the technical resources by which it is possible to achieve maximum productivity values, with minimum impact on the environment, which are requested by their users these days. It further approaches on trends in the area of the precision agriculture and provides a list of innovations which have the potential to streamline systems of tillage and crop production. Finally, the thesis analyses the output of parameters of the kit Case IH Quadtrack and Horch Tiger Lt. This is in particular the dependence of values such a performance and hectare consumption on the operating mode of the engine. This analysis was based on data collected during field measurement on 30th March 2016 on land owned by company called Roštenice a.s.
PCM-based heat and cold storage
Němec, Lukáš ; Ostrý, Milan (referee) ; Šikula, Ondřej (advisor)
In the first part of the bachelor thesis I will deal with the accumulation of heat and cold using materials with phase change and also the design of a PCM storage tank. The aim of my effort is to design the most ideal spacing of tubes in a given tank, so as to achieve the greatest possible heat capacity. I performed simulation experiments in CalA 4.0. The second part is computational, where I focus on the design of heating in the pension. I solve heating with an air-to-water heat pump. I designed solar collectors for hot water heating. The last and third part is the project, which contains the project documentation together with the technical report.
The world of work through the perspective of state, labour unions and employers. Building a hegemony.
Němec, Lukáš ; Lánský, Ondřej (advisor) ; Májíček, Jan (referee)
(in English): During adolescence, a person's value orientations towards society, employment, and the economy are being shaped significantly. The educational system plays an important role in this maturing of a person's values in that it provides key social orientation in the form of knowledge, consciousness, or opinions. The theory of cultural and social reproduction was among the first analyses of critical education that drew attention to the fact that this mediation of orientation serves for the maintaining (reproduction) of social inequalities in society. The basic question of education according to these analyses of critical education thus is not what knowledge we get at school, but rather whose knowledge. In the Czech Republic, ca. 73% of pupils go through secondary vocational training. After graduation, most of these pupils are the first to enter the world of paid labor at a relatively early age. Between 2004 and 2012, intermediate vocational training underwent a change of system in the form of the implementation of curriculum reform in connection with the adoption of Act No. 561 / 2004 Coll. on Preschool, Elementary, Secondary, Tertiary Vocational, and Other Education. Curriculum reform enabled various social agents to influence the goals and content of education at the national level...
Optimal Path Planning for Omnidirectional Robot
Němec, Lukáš ; Kapinus, Michal (referee) ; Rozman, Jaroslav (advisor)
The work is devoted to planning trips for robot, which is equipped with Mecanum omnidirectional wheels and a square carriage. The theoretical part is devoted omnidirectional wheels and various types of planners With a focus on informed planners, locating the position and movement of optimality. The practical part is devoted to the implementation of selected planners and comparing their results in terms of optimality of movement for omnidirectional robot, optimality check consists of comparing several properties of the proposed path.
Comparation of The Dutch and American pension system (2015)
Němec, Lukáš ; Brabec, Petr (advisor) ; Lukášová, Tereza (referee)
This bachelor thesis is focused on the problematic of systems of old age security pension in the Netherland and the United States of America. The theoretical part attemps to introduce the breakdown of pension systems according to the financing method, the operator, or the construction of pension benefits. The practical part deals with the brief presentation of history of pension systems, the demographic situation in the monitored countries and the analysis of the state of pension systems according to individual pillars. The aim of the thesis is to analyse and to compare the state of pension systems in selected countries and to propose changes for the pension system of the Czech Republic. This bachelor thesis concludes that the Netherlands pension system is more advantageous and better set than the system in the USA. Therefore, the outcome of the thesis is that the Dutch pension system is a convenient inspiration for the Czech pension system.
He who doesn't work, neither shall he eat, shan't he? The image of work in the debate about a basic income.
Němec, Lukáš ; Hrubec, Marek (advisor) ; Slačálek, Ondřej (referee)
This work will focus on the relationship between basic income and work. We will pursue how the work is reflected in debates on basic income, and seek other arguments for universal basic income through a new rethinking of work. To be able to thematize the new rethinking of work, however, the politicization of work is required. In our work, we will focus on the history of basic income, its normative justification and essential characteristics. We will address basic income and the financial crisis. We will also show how the work has been thematized in the society since its "modern" discovery in the 18th century. With Dominique Méda, we will describe three images of work: the Smithian concept of work, the images of work associated with the thinking of Karl Marx, and the image of work connected with the origin of the welfare state. All these images of work are reflected by basic income. Eventually, we will demonstrate for basic income being able to be an instrument of the politicization of work, it has to abandon the Smithian concept of work.
Localisation of Mobile Robot in the Environment
Němec, Lukáš ; Hradiš, Michal (referee) ; Veľas, Martin (advisor)
This paper addresses the problem of mobile robot localization based on current 2D and 3D data and previous records. Focusing on practical loop detection in the trajectory of a robot. The objective of this work was to evaluate current methods of image processing and depth data for issues of localization in environment. This work uses Bag of Words for 2D data and environment of point cloud with Viewpoint Feature Histogram for 3D data. Designed system was implemented and evaluated. 
Analýza vybraných parametrů spalovacích motorů
Němec, Lukáš
The thesis introduces and briefly describes the technologies which are applied in modern diesel engines used in agricultural industry. They are facilities with which it is possible to achieve the maximum productivity, with minimal impact on the environment, which is now required by users. It also describes future trends in engine design and offers a list of innovations, which are currently under the development and have got the potential to improve parameters of diesel engines in the future. There are also described characteristics of combustion engines, according to which are the selected parameters assessed. Last but not least, the work deals with the analysis of selected parameters of the internal combustion engine depending on their structural design. This analysis was based on data obtained from the Institute of DLG and independent testing laboratory of motor vehicles at the University of Nebraska.
The analysis of financing options for executing new thermal insulation of an apartment building including the proposal of optimal amount of repairs fund

The subject of the work is put forward and evaluate different financing options including thermal insulation of residential building list of essential criteria and generalization optimal procedure. Analysis of the individual components of long-term backup or repair fund, determining the optimum amount of funding inserted before insulation. Determine which folders and to what extent will be affected by thermal insulation of the house. Part of this work is to determine the normal price of a residential building as a whole and explanations of technical terms.
Object Detection Using Kinect
Němec, Lukáš ; Veľas, Martin (referee) ; Španěl, Michal (advisor)
This paper address the problem of object recognition using Microsoft Kinect in the fi eld of computer vision. The objective of this work was to evaluate current methods of detection of objects using depth map (RGB-D sensor). The work deals with the enviroment of point cloud and Viewpoint Feature method. It also describes the use of binary classifi er in the context of object recognition. Object detection was implemented and performed experiments with it.
