Právo i dobro Argumentace a diskurs českých aktivistek za volební právo pro ženy / Right and good : Argumentation and Discourse of Cze ch Activists for Women's Suffrage

Gelnarová, Jitka January 2013 (has links)
Right and good : Argumentation and Discourse of Czech Activists for Women's Suffrage Jitka Gelnarová Abstract The dissertation deals with the concept of suffrage within the discourse of Czech women's suffrage activists between 1897 and 1914. The aim is to define how the concept of suffrage was constructed by Czech suffragists within the context they lived in, how their notion of the suffrage was influenced by the fact that different women were positioned differently within the system of hierarchies based on gender, class and nation. The dissertation focuses on the hierarchies present in the discourse; the relation of "public" and private" in the discourse; the notion of "political representation" in the discourse; positions the suffragists spoke from and their representation of the enemy ("us/them"); the functions the concept of "Czechness" fulfilled in relation to the demand of female suffrage in the discourse; and the relation of "universality" and "particularity" to the demand of female suffrage in the discourse.

Dolování víceúrovňových sekvenčních vzorů / Mining Multi-Level Sequential Patterns

Šebek, Michal January 2017 (has links)
Dolování sekvenčních vzorů je důležitá oblast získávání znalostí z databází. Stále více průmyslových a obchodních aplikací uchovává data mající povahu sekvencí, kdy je dáno pořadí jednotlivých transakcí. Toho může být využito například při analýze po sobě jdoucích nákupů zákazníků. Tato práce se zabývá využitím hierarchického uspořádání položek při dolování sekvenčních vzorů. V rámci práce jsou řešeny dvě základní oblasti - dolování víceúrovňových sekvenčních vzorů s křížením a bez křížení úrovní hierarchií. Dolovací úlohy pro obě oblasti jsou v práci formalizovány a následně navrženy algoritmy hGSP a MLSP pro jejich řešení. Experimentálně bylo ověřeno, že především algoritmus MLSP dosahuje výborných výkonnostních vlastností a stability. Význam nově získaných vzorů je ukázán na dolování reálných produkčních dat.

There Is Softness Hidden in Your Walls : A Material Exploration Uncovering the Textile Elements in Building Construction

Salvall, Lisa January 2023 (has links)
A wall might appear as basic, a clean surface without an identity of its own, nothing but a clean slate upon which to leave any impression. Though the walls surrounding us are all but anonymous. They are built with a structure making them stand tall and strong. They are filled with insulation to keep us warm and sheltered. They are hard and they are soft. They can allow us to isolate ourselves from each other or they are fragile enough to let us know someone is on the other side. They cover the basic necessities of our houses, and we in return cover them to make our spaces less anonymous. There is softness hidden in your walls mainly aims to highlight the textile components of architecture which we usually never see. While we tend to view textiles mostly as decoration, they constantly perform in a lot of various ways all around us. In this project I have worked with prefabricated building materials that according to me have textile qualities, but they aren’t viewed as textile. Or I have tried to adapt textile techniques to non-textile materials to test them in new ways. The wall as the leading actor has first and foremost been used as a conversation partner for the material exploration and contextualization. The main material used is wool sheep insulation though many other materials have been put to the test throughout the process.

Route Planning of Battery Electric Heavy-Duty Commercial Vehicles : Using Contraction Hierarchies and Mixed Integer Programming

Delborg, Olle, Insulander, Elias January 2023 (has links)
This thesis addresses route planning of Battery Electric Heavy-Duty Commercial Vehicles to enhance the reliability of electric vehicle transport. Collaborating with Scania, a Swedish truck manufacturing company, the goal is to develop a pipeline that uses open source data from OpenStreetMap and performs a modified Contraction Hierarchy in order to create a graph that can be used as input to a modified Vehicle Routing Problem formulation using Mixed Integer Programming. The input graph is preprocessed to support a Battery Electric Heavy-Duty Commercial Vehicle model in order to more accurately predict energy consumption. The challenges lie in balancing computational efficiency and electric vehicle characteristics. The implemented pipeline demonstrates success but initial tests show that a naive version of the pipeline, not implementing Contraction Hierarchies, can perform better. Several speedups can be made in order to improve the efficiency of the pipeline, the main being in programming in a more efficient programming language than Python. Further testing is needed for larger input graphs to assess performance accurately.

[pt] O FORMALISMO CLOCKWORK PARA HIERARQUIAS NATURAIS DE FÉRMIONS / [en] THE CLOCKWORK APPROACH TO NATURAL FERMION HIERARCHIES

FERNANDO ABREU ROCHA DE SOUZA 02 August 2019 (has links)
[pt] O Modelo Padrão de física de partículas é uma das teorias mais bem estabelecidas no campo da física, sendo capaz de fazer previsões verificadas experimentalmente até doze algoritmos significativos. No entanto, o Modelo deixa algumas perguntas sem resposta, o que vem perturbando os físicos por muitos anos. Uma dessas questões é a estrutura hierárquica presente no setor dos férmions, onde matrizes Yukawas possuem autovalores que diferem um do outro por várias ordens de magnitude. Outro aspecto cabível de investigação é relacionado com a matriz CKM, responsável pela mistura entre férmions de sabores distintos. Por que tal matriz é aproximadamente diagonal e por que os ângulos de mistura são tão pequenos? Por que o elétron é muito mais leve que seus primos de outras gerações? A mesma pergunta pode ser feita para os quarks e o Modelo Padrão não seria capaz de responder nenhuma delas. Nesse trabalho, uma explicação proposta vem da utilização de um novo modelo, chamado de Mecanismo Clockwork, que pressupõe a existência de novos férmions pesados, nomeados Clockwork Gears, que são capazes de naturalmente gerar acoplamentos exponencialmente suprimidos a partir de Yukawas de ordem um, após a ocorrência de quebra espontânea de simetria. Além disso, simulações foram feitas com o objetivo de otimizar os parâmetros livres do modelo, assim como confirmar sua eficiência em acomodar os dados experimentais. Por fim, foi feita uma análise de alguns processos, envolvendo correntes neutras que trocam sabor, no regime de teoria efetiva de campo, para poder-se estipular um limite para a escala típica de massa para essas novas partículas. / [en] The Standard Model of particle physics is one of the most well established theories in the field of physics and is able to make predictions correctly measured and verified up to twelve significant figures. However, the theory leaves some unanswered questions that have been bothering physicist for many years. One of those questions is the hierarchical structure of the fermion sector, where Yukawa matrices have eigenvalues that differ from each other by several orders of magnitude. Another aspect concerns the CKM matrix, which dictates the mixing between fermions of distinct flavours: why is this matrix almost diagonal, and why are the mixing angles so small? Why is the electron so much lighter than its cousins from different generations? The same question could be made for the quarks and the Standard Model would not be able to answer neither of these. In this work, an explanation is proposed by employing a novel model, called Clockwork Mechanism, which assumes the existence of new heavy fermion particles, named Clockwork Gears, which are able to naturally generate exponentially suppressed couplings out of order-one Yukawas, after spontaneously symmetry breaking occurs. In addition, simulations were run in order to optimize the free parameters of the model, as well as to confirm its efficiency at fitting with experimental data. Lastly, a few processes involving Flavour Changing Neutral Currents were considered in the effective field theory regime as a means to stipulate a typical mass scale for these new particles.

Shopping centre development strategies for emerging markets in KwaZulu-Natal

Warrington, Neville Harold 01 January 2002 (has links)
Summaries in English and Afrikaans / The first fully enclosed, airconditioned shopping mall in a black township in South Africa opened in 1979 in Umlazi, outside Durban. The provincial development corporation (lthala) spearheaded emerging market shopping centre development in KwaZulu-Natal to the extent that, with the involvement of the private sector, substantial knowledge and experience have been gained in shopping centre development in emerging markets over the past two decades. The study focuses on black shopping patterns and household income and expenditure in townships and rural areas in KwaZulu-Natal. The assessments include: • empirical trade areas; • geodemographics and geographic infonnation systems (GIS); • buying power modelling; • market share estimates; • retail hierarchies; • viability and feasibility studies; • centre design (including taxi rank developments); • informal trading; and • tenant mix; location; financing and research strategies. The study fonnulates a universal buying power model for KwaZulu-Natal that transcends ethnic and geographic classifications, to enhance, with the aid of computer technology and census information, the accuracy and cost effectiveness of viability and feasibility studies in shopping centre development. An IntegJ.-ated Commercial Assessment Model (JCAM) is formulated whereby demographic data of a trade area and financial feasibility parameters are integrated to assess the viability of a shopping centre. The study concludes that although there are many unique features associated with shopping centres in emerging market locations, the :fundamental principles that apply all over the world in shopping centre development, also apply to emerg1ng markets in KwaZulu-Natal. Relatively low disposable incomes limit the sustainable size of the emerging market shopping centre. Shopping centre locations are linked to the interdependence on public transportation by emerging market patrons. Factors conducive fo-r shopping centre development, such as high private vehicle ownership, high disposable income, willing retailers, effective town planning and state assistance, have not yet reached levels that would benefit the widespread development of shopping centres in townships. Emerging market shopping centre developments in the central business districts of rural towns, however, have been generally very successful and are setting the benchmarks in South Africa. / Die opening van die eerste ingeslote winkelsentrum met sentrale lugreeling in 'n swart woonbuurt in Suid-Afrika, het in 1979 in Umlazi (buite Durban) plaasgevind. Die provinsiale ontwikkelingskorporasie (Ithala) het aan die spits van winkelsentrum ontwikkeling in opkomende markte in KwaZulu-Natal gestaan. Die toetrede van die privaatsektor tot die mark het verder ook substansieel bygedra tot kennnis en ondervinding in winkelsentrumontwikkeling oor twee dekades in opkomende markte. Hierdie studie fokus op swart kooppatrone en huisgesin inkomste and uitgawes in swart woonbuurtes en landelike gebiede in KwaZulu-Natal. Die ondersoeke sluit die volgende in: • empiriese handelsgebiede; • geodemografie en geografiese inligtingstelsels (GIS); • koopkrag modellering; • markaandeel skatting; • kleinhandel hierargie; • lewensvatbaarheid en uitvoerbaarheid studies; • sentrum ontwerp (ingesluit taxi staanplek ontwikkelings); • informele handel; en huurdersamestelling, ligging. finansiering en navorsingsstrategie. Die studie formuleer 'n universele koopkrag model vir KwaZulu-Natal wat etniese en geografiese klassifikasies oorskry en met die hulp van 'n rekenaar en sensus inligling, die akkuraatheid en koste effektiwiteit van lewensvatbaarheid en uitvoerbaarheid studies in winkelsentrum ontwikkeling, moontlik maak. 'n Geintegreerde kommersiele evalueringsmodel (GKEM) is geformuleer waarmee demografiese data van 'n handelsgebied en finansiele data geintegreer word om die lewensvatbaarbeid van 'n winkelsentmm te evalueer. Die studie kom tot die gevolgtrekking dat, ongeag die baie unieke eienskappe van winkelsentrums in opkomende markte, die fundamentele reels wat reg oor die wereld met winkelsentrumontwikkeling toegepas word, ook vir die opkomende markte van KwaZulu-Natal geld. Relatief lae besteebare inkomstes beperk die drakrag grootte van winkelsentmms in opkomende markte. Winkelsentrumliggings word verbind met die interafhanklikheid van publieke vervoer van die marksegment. Faktore gunstig vir winkelsentrumontwikkeling soos hoe privaatmotorbesit, hoe besteebare inkomste, gewi1lige kleinhandelaars, effektiewe stadsbeplanning en staatsondersteuning het nog nie vlakke bereik wat die grootskaalse ontwikkeling van winkelsentrums in swart woonbuurtes bevoordeel nie. Winkelsentrumontwikkeling in die sentrale sakegebiede van landelike dorpe is wel, in die algemeen, suksesvol en stel tans die standaard vir winkelsentrumontwikkeling vir opkomende markte in Suid Africa. / Geography / D.

I like it dirty

Pontén, Stina January 2018 (has links)
Using dirt and cleaning as a point of departure, I have examined how categorization and intentionality affects our perception of value. The work is partly performative in its nature where this performativity sets the limelight on the transition between categories: From dirt to craft, from irrational behaviour to art. In the artistic process, I have used coffee rings on table cloths, shoeprints on wallpapers and  the act of mopping as a means of questioning. Through this, I also reveal and question hierarchies in society. The essay discusses and theoretically relates to the artistic work. / Med utgångspunkt i smuts har jag underökt hur kategorisering och intentionalitet påverkar vår uppfattning av värde. Arbetet är delvis performativt till sin natur, där denna performativitet sätter fokus på övergången från en kategori till en annan: Från smuts till konsthantverk, från irrationellt beteende till konst. I den konstnärliga processen har jag använt mig av kafferingar på dukar, skoavtryck på tapeter och moppande av golv som medel för ifrågasättande. PÅ detta vis blottlägger och ifrågasätter jag hierarkier i samhället. I uppsatsen diskuterar jag och relaterar teoretiskt till det konstnärliga arbetet.
