The Study of Inventory Management in Connection with Manufacturing Process
Tieber, Michael ; Klíma, Jan (referee) ; Jurová, Marie (advisor)
This master’s thesis deals with problems of inventory management in the International Repair Centre for Symbol Technologies Czech Republic s.r.o.. Actual inventory management is described with a focus on materials planning, storage and evidence of inventory movements using information database systems. A part of the thesis is also an analysis of inventory categories from several different aspects. The purpose of the master’s thesis is to submit suitable suggestions of how to improve existing inventory management processes.

Spin waves in non-trivial magnetic landscapes
Klíma, Jan ; Staňo, Michal (referee) ; Wojewoda, Ondřej (advisor)
Magnonics is a branch of physics dealing with spin waves, or their quanta – magnons. Spin waves are one of the candidates for beyond CMOS technology. Circuits and components utilizing the properties of spin waves have the potential to complement or replace the current technologies based on CMOS chips, which are nearing their physical limit. Information processing via spin waves requires the ability to effectively steer spin waves in magnonic circuits, especially in variously bent waveguides connecting individual circuit elements. Due to spin waves’ anisotropic behaviour, this remains on of the challenges to tackle. In the presented thesis, we used corrugating of the magnetic layer of the waveguides, which induces uniaxial magnetic anisotropy, with which we can control the magnetisation landscape in the waveguide with sub-micrometre precision. Using this approach, we can achieve zero-field-propagation of spin waves in desired modes in arbitrary directions. To aid our designs, we developed a model that analyses energy contributions and calculates the resulting effective magnetic field. Using this model and a thorough analysis of the dispersion relation, we designed a bent magnonic waveguide capable of steering spin waves, which we demonstrated by Brillouin light scattering microscopy.

Academical crise 1969 in Coimbra
Vondrašová, Jana ; Binková, Simona (advisor) ; Klíma, Jan (referee)
The diploma thesis Akademická krize 1969 v Coimbře (The 1969 Academic Crisis in Coimbra) discusses the Coimbra Academic Crisis in both the Portuguese and international contexts. The assessment of the validity of the thesis that the Portuguese student movement in the late 60s was a part of the international movement of '68 is based on the study of sociological theories of social movements and on the comparison with historical events in economically developed democratic countries - United States, Germany, France and Italy. Portuguese student movements were from the beginning connected with student organisations, the so-called associations, which were attempting to change the legislative framework of out-of-school activities. In the authoritative regime of António de Oliveira Salazar, the so-called New state, the primary function of universities was to raise ideologically conscious elites. The restrictive character of the above-mentioned legislative enabled government control of student life. The protest leaders usually maintained contacts with political opposition and subordinated the aims of the movement to the interests of the illegal Communist Party. As a rule, the government did not have difficulties dealing with the relatively small activist groups, and persecution by police led effectively to the...

Systém pro vektorizaci rastrových obrázků
Klíma, Jan ; Skopal, Tomáš (advisor) ; Kopecký, Michal (referee)
The task of shape extraction is very complex and hasn't yet been satisfactorily solved. Although there exist lots of algorithms for shape extraction, the mere knowledge of such techniques doesn't give us an answer what methods should be used and how to combine them in order to obtain robust extraction method. This thesis is devoted to creating a component system for image vectorization, which is designed to allow easy configuration of shape extraction data-flows. The system's description is followed by a component catalogue that offers basic algorithms for image processing, vectorization and vector output handling. Component configurations as well as typical network scenarios are covered briefly. The proposed system is then compared to similar applications.

Presence of Colonial Past in Contemporary Portugal
Tošnerová, Barbora ; Rovná, Lenka (advisor) ; Klíma, Jan (referee)
This diploma thesis, titled "Presence of Colonial Past in Contemporary Portugal", deals with how the Portuguese society has coped with their loss of the last colonies after the democratic revolution in the year 1974. Portugal belonged, along with Spain, to the first colonial powers in Europe and for long time - till the 20th century - the independence of colonies was for many Portuguese people unimaginable. Therefore a lot of them were surprised with the speedy decolonization of these territories after 1974. Investigation of reactions of Portuguese society to this change is based on the analysys of responses of its political and academic communities after the year 1976. Attitudes held by the wider society was demonstrated by the massive support of Portuguese to the former colony of East Timor during Semptember 1999. The approach of politicans is analysed in this work through their speeches during the key' historical moments, which influenced relations between Portugal and its former colonies during the years 1976-1996, as well as through government' programmes and comments in mass media. Analysis of academical discussion is concentrated mainly on the 1990s and present, when the colonial past has became a topic of great interest to many portuguese perits. A new field of academic interest, reffered...

Politics and society in Angola in the 1970s: MPLA' s struggle for the consolidation of power
Caetano Joáo, Mário Augusto ; Kumsa, Alemayehu (advisor) ; Klíma, Jan (referee) ; Kropáček, Luboš (referee)
Politics and Society in Angola in the 70's of the 20th century: MPLA's struggle for the consolidation of power is a rigorous and meticulous work on the internal dynamics existing in MPLA, first as a movement and then as a political party, through the greatest moments, which in its development occurred. The seventies of last century represent the biggest crisis in the history of the Angolan strongest political party ever. The work seeks to highlight the political consequences but also consequences in human lives that these crises have influenced. During the 70's of the 20th century four major events bring MPLA on the verge of liberation process. On the eastern front, at the beginning of the seventies, there was an uprising in the MPLA army against the central leadership. Later, Daniel Chipenda, a member of the MPLA Steering Committee, took the lead of the rebellion. In terms of leadership in MPLA, this was the first major collapse between the Steering Committee and the MPLA social and rural bases. Right after took place another revolt, which was called Active Revolt, in May 1974 in Brazzaville, Republic of Congo where MPLA had its headquarters. It was carried out by mostly intellectual dissidents, but it brought structural catastrophic consequences for MPLA, when the 25th April 1974 in Portugal played a coup...

Morphological indications of water activity on Mars
Klíma, Jan ; Kalvoda, Jan (advisor) ; Šobr, Miroslav (referee)
Morphological indications of water activity on Mars Bachelor thesis deals with morphological indications of water activity on the Mars surface. In the papers are summarized and characterized the structures and forms on the surface of planet Mars, which originated in the past by water in gaseous, liquid or solid form. Based on research articles and expert studies, a bachelor thesis has been composed. It provides the summary of shapes on the Mars surface, which were created by water activity. There are many water formed parts of the Martian surface nowadays: valley networks, an extensive basin in the northern hemisphere, which is the remnant of antient ocean, craters lakes in the past, water bound as a solid component of polar caps and many others. The development of water-formed shapes of the Martian surface is described, and these shapes are also located on a brief map. In presented study is elaborated a comprehensive and complex view to morphological indications of the water activity on Mars.
