Časově-frekvenční vztah mezi spotovými a termínovanými cenami ropy / The time-frequency relationship between spot and futures prices of crude oil

Tran Quang, Tuan January 2016 (has links)
This thesis investigates the relationship between daily spot and futures prices for maturities of one, two, three and four months of West Texas Intermediate (WTI) crude oil. The data cover period January 1987-April 2015. Based on economic theory, the futures prices should be closely related to the spot price, which - in the case of crude oil market - this thesis analyses using wavelet-based approach. Main contributions of this thesis are findings in the field of time-frequency relationship of spot-futures prices of crude oil, where an alternative methodology - wavelet transformation - is used. The usage of this advanced method is also an additional contribution of this thesis because it allows us to rigorously study how co-movement (relationship) differs across frequencies/scales and time. In this thesis wavelet Coherence, wavelet bivariate correlation and relatively new method wavelet band spectral regression (WBLS) are used. This thesis brings 4 main findings. First, relationship between Futures and spot prices of crude oil is strong in all time-periods (frequencies/scales), which supports economic theory. Second and In contrary to the first finding, in the gasoline spot-futures market, we find that the relationship is strong mainly in higher scales (lower frequencies) while in lower scales (higher...

Tradition and transformation : a critique of English setwork selection (2009-2011).

Silverthorne, Rosemary Ann 15 March 2010 (has links)
This Research Report critiques the English Home Language Literature setwork selection for the period 2009-2011 in terms of the National Curriculum Statement for English Home Language for Grades 10- 12 to establish whether there is consonance between policy and practice in this section of the syllabus and to determine whether the new national syllabus offers a traditional or a transformational approach to the subject. In order to do this, the National Curriculum Statement is analysed in terms of the principles and outcomes which it intends to be actualised in the study of English and selects those that seem applicable to literature studies. Questions are formulated encapsulating these principles and used as the tools to critique the new national literature syllabus both as regards its individual constituent parts and as regards the syllabus as a whole. A brief comparison between the current prescribed literature selection and setworks set from 1942 to the present day establishes whether the new syllabus has departed from old syllabus designs, whether it acknowledges the new target group of pupils in multiracial English Home Language classrooms by offering a revised, wider and more inclusive selection of novels, dramas, poems and other genres such as short stories, or whether it remains traditionally Anglocentric in conception. The conclusions reached are that although the setworks conform to the letter of the requirements set down in the NCS, the underlying spirit of transformation is not realised. The inclusion of some poets from Africa and South Africa is merely content addition to a Eurocentric core curriculum, a form of tokenism which does not reorientate the syllabus significantly or move it away from its traditional trajectory. The report suggests that literature of merit from both Africa and South Africa be included in every part of the syllabus so that it reflects in some degree the contributions that the continent makes to English literature, in this way including in its scope the interests and identities of the wide range of learners studying English Home Language in the South African context.

Modeliavimu grindžiamas J2EE platformos trijų sluoksnių informacinių sistemų kūrimas / Model-driven development of 3-tier JEE platform applications

Mikuckas, Modestas 20 June 2012 (has links)
Viena iš technologinių sričių, kur galima pritaikyti modeliavimu grindžiamą architektūrą (MGA) yra Java Enterprise Edition (J2EE) informacinių sistemų kūrimas. Nors generuoti pilną programinį kodą taikant MGA metodus nėra įprasta, tačiau egzistuoja abstraktūs metodai, bei daliniai sprendimai leidžiantys daryti prielaidą, kad tai yra įmanoma. Remiantis egzistuojančiais abstrakčiais metodais ir daliniais sprendimais buvo sukurtas MGA metodas ir kodo generatorius, leidžiantis sugeneruoti visą programinį kodą pagal modelio duomenis. Sukurtas metodas buvo išbandytas su realia informacine MagicTest žinių testavimo sistema. Bandymas su realia sistema parodė, kad pasiūlytas MGA metodas gali būti sėkmingai taikomas JEE platformos informacinių sistemų kūrimui. / One of the technological areas where can be used model driven architecture (MDA) is Java Enterprise Edition (J2EE) development of information systems. Although to generate a complete program using MDA is not common, but there are some abstract methods, and partial solutions suggesting that this is possible. Based on existing methods of abstract and partial solutions new MDA method and code generator was created. Generator allows to generate software code based on the model data. The method and generator was tested with the real information MagicTest knowledge testing system. The test of the real system showed that the proposed MDA method can be successfully applied to J2EE platform for developing information systems.

Art e miss

Samiotaki, Argyri Roula January 2023 (has links)
The project of Art e miss is a moving practice and research, an embodied exploration of the wild woman archetype. The research is aiming to practice ways to mobilize one-female-self in situations of feeling restricted. It is about approaching ways of mobilizing oneself to act and transform situations and moments of friction.  On a personal level, it works with the question ‘How can I overcome situations in which I feel restricted? How can I transform those situations into situations that support me and my desires?’ On a political level, it is a feminist practice for imagining and proposing alternatives. It tries to empower the female to seek possible different responses against dominant ideas and structures of oppression. For exploring this question within the field of dance and movement, the project of Art e miss uses imagination, playfulness, and modes of relating to generating mobility and movement. The project uses strict scores to generate the structure in which the performers can practice. In this structure, the performers practice spontaneously reacting at the moment through improvised dances and mobilizing themselves as a response to the restrictions of the task. / Performative and mediated practices, with specializations in choreography

A Variable Resolution Global Spectral Method With Finer Resolution Over The Tropics

Janakiraman, S 08 1900 (has links)
Variable resolution method helps to study the local scale phenomenon of interest within the context of global scale atmosphere/ocean dynamics. Global spectral methods based on spherical harmonics as basis functions are known to resolve a given function defined on the sphere, in an uniform manner. Though known for its mathematical elegance and higher order accuracy, global spectral methods are considered to be restrictive for developing mesh-refinement strategies. The only mesh refinement strategy available until now is due to the pioneering work of F. Schmidt. Schmidt transformation can study only one region with higher resolution. The study of tropical dynamics is an interesting theme due to the presence of teleconnections between various phenomena, especially Indian Monsoon and the El-Nino. The Inter-Tropical Convergence Zone (ITCZ)is a continental scale phenamenon. It is in the ITCZ, many monsoon systems and tropical cyclones do occur. To study such phenomena under variable resolution method, high resolution is required in the entire tropical belt. Hitherto such a kind of mesh refinement strategies were not available in global spectral models. In this work, a new variable resolution method is developed that can help to study the tropical sub-scale phenomena with high resolution, in global spectral models. A new conformal coordinate transformation named ’High resolution Tropical Belt Transformation(HTBT)’ is developed to generate high resolution in the entire tropical belt. Mathematical demonstrations are given to show the existence of additional conformal transformations available on the sphere, indicating additional degrees of freedom available to create variable resolution global spectral method. Variable resolution global spectral method with high resolution over tropics is created through HTBT. The restriction imposed by Schmidt’s framework that the map-ping factor of the transformation need to have a finite-decomposition in the spectral space of the transformed domain is relaxed, by introduction of a new framework. The new framework uses transformed spherical harmonics Bnm as basis for spectral computations. With the use of FFT algorithm and Gaussian quadrature, the efficiency of the traditional spectral method is retained with the variable resolution global spectral method. The newly defined basis functions Bnm are the eigenvalues of the transformed Laplacian operator . This property of Bnm provide an elegant direct solver for the transformed Helmholtz operator on the sphere. The transformed Helmholtz equations are solved accurately with the variable resolution method. Advection experiments conducted with variable resolution spectral transport scheme on the HTBT variable grid produces near-dispersion free advection on the tropical belt. Transport across homogeneous resolution regions produce very less dispersion errors. Transport of a feature over the poles result in severe grid representation errors. It is shown that an increase in resolution around the poles greatly reduces this error. Transport of a feature from a point close to poles but not over it, does not produce such representation errors. Fourth-order Runge-Kutta scheme improves the accuracy of the transport scheme. The second order Magazenkov time-scheme proves to be better accurate than the leap-frog scheme with Asselin filter. The non-divergent barotropic vorticity equation is tested with two exact solutions namely Rochas solution and Rossby-Haurwitz wave solutions. Each of the solution tests certain unique and contrasting characteristic of the system. The numerical behaviour of the solutions show non-linear interactions in them. The singularity at the poles, arising due to the unbounded nature of the latitudinal derivative of the map factor of HTBT, triggers Gibbs phenomena for certain functions. However the recent advances in spectral methods, especially spectral viscosity method and Boyd-Vandeven filtering strategy provide ways to control the Gibbs oscillation and recover higher accuracy; make the variable resolution global spectral method viable for accurate meteorological computations.

Projektová výuka v prostředí malotřídní školy / Projects learning in primary school settings

Dokoupilová, Pavla January 2018 (has links)
The diploma thesis on the subject of Project education in a littleclass school raises a research question: Does the inclusion of a project education in a littleclass school help to develop pupils key competencies? The aim is to describe, analyse and evaluate the use of project education at the primary level of a littleclass school. In here project education is understood as one of the possibilities of realising educational content, which is defined by the Framework Educational Program for elementary education. The thesis is divided into two parts - theoretical and practical. The theoretical part is based on the transformation of the Czech education after 1989. It points out the humanisation program of school reform and constructivist approaches in teaching. It deals with the characteristics of project education, typologies and phases of the project. It familiarises itself with the specifics of a littleclass school and with the possibility of incorporating project education into this type of school. It points out the positives, but maybe even the dificulties of project education. The practical part deals with the realization and reflection of several projects in the littleclass school with regard to the specifics of this type of establishment. On the basis of the analysis, it tries to assess whether...

L’oncogène Src et les protéines de la famille Bcl-2 : une coopération coupable : implication de la protéine Bik dans la résistance à l’apoptose de cellules transformées par l’oncogène Src / The src oncogene and the Bcl-2 family proteins : a guilty cooperation : Implication of the Bik protein in the resistance to apoptosis of Src-transformed cells

Lopez, Jonathan 04 May 2010 (has links)
La protéine tyrosine kinase c-Src est surexprimée et activée dans de nombreux cancers. De manière remarquable, Src est activé dans plus de 80% des adénocarcinomes coliques où il joue un rôle dans la carcinogenèse et la progression vers un phénotype métastatique. c-Src et son homologue viral v-Src activent un grand nombre de voies cellulaires permettant à la tumeur de proliférer, de résister à la mort cellulaire et d’acquérir des capacités accrues de migration et d’angiogenèse. Au cours de ma thèse nous avons mis en évidence un mécanisme inattendu d’échappement à l’apoptose de fibroblastes murins surexprimant de manière stable v-Src et de plusieurs lignées tumorales humaines (coliques en particulier) présentant une activité c-Src dérégulée. Nous avons montré que Src stimule la dégradation protéasomedépendantede la protéine Bik, un membre pro-apoptotique de la famille Bcl-2, connu pour être un suppresseur de tumeurs. Cette régulation post-traductionnelle du niveau d’expression de Bik est à l’origine d’une forte résistance de la voie mitochondriale de l’apoptose. L’inhibition de l’activité kinase de Src ou le blocage de la dégradation de Bik par le protéasome permettent de restaurer des concentrations normales de la protéine Bik dans les cellules transformées et de les restaurer efficacement l’apoptose. En revanche, l’inhibition des protéines anti-apoptotiques de la famille Bcl-2 par l’ABT-737 semble moins efficace. Par ailleurs, nous avons également contribué à mettre en évidence le rôle anti-migratoire et anti-invasif du lithium sur des cellules transformées par Src. Le mécanisme moléculaire mis en jeu implique l’activation redox des protéines tyrosine phosphatases cellulaires. Enfin, nous avons participé à l’étude de peptides mimant les hélices centrales d’insertion de Bax, Bcl-xL et Bid, représentant les trois sous-groupes de protéines de la famille Bcl-2. Nous avons comparé leur comportement vis-à-vis d’une monocouche lipidique mimant la membrane mitochondriale externe ainsi que leur capacité à perméabiliser des mitochondries isolées. Nos résultats nous ont permis de proposer que les fragments centraux d’insertion membranaire des protéines Bcl-2 seraient directement impliqués dans la divergence fonctionnelle des différents sous groupes qui composent la famille / C-Src tyrosine kinase is overexpressed and activated in a number of cancers. Remarkably, Src is deregulated in more than 80% of colorectal adenocarcinoma, playing a role in carcinogenesis and progression toward a metastatic phenotype. c-Src and v-Src activate a large number of intracellular pathways which allow the tumor to proliferate, to evade the cell death machinery and to acquired enhanced migratory and angiogenic abilities. During my PhD, we discovered an unknown mechanism to evade apoptosis developed by murine fibroblasts stably overexpressing v-Src and by some human tumor cell lines with c-Srcb deregulation. We have shown that Src stimulate the proteasomal degradation of the Bik protein, a proapoptotic member of the Bcl-2 family proteins known to act as a tumor suppressor. This post-translationnal regulation of the Bik protein expression level leads to a strong resistance of the mitochondrial pathway of apoptosis. Inhibition of the Src kinase activity or of the Bik proteasome-dependent degradation restore normal levels of the Bik protein and efficiently resensitize these cells to apoptosis. Inhibition of the antiapoptotic Bcl-2 proteins by ABT737 seems to be less efficient in these cells. We also contribute to show that lithium suppresses motility and invasivity of v-Src transformed cells. The molecular mechanism involve a redox activation of the protein tyrosine phosphatases. Finally, we compared the membrane behavior and the ability to permeabilize mitochondria of synthetic peptides derived from the central helical hairpin of Bax,Bcl-xL and Bid. We showed that these structurally analogous domains have distinct membrane behavior which could account for the functional divergence between the Bcl-2 family members
