Full textThe Swedish model of elite sports secondary schools consist of Riksidrottsgymnasium, RIG,and National Sports Education Programs, NIU, which offer a training program with specialized sports to student-athletes in order for them to combine sport and study. The underlying philosophy for the model is seen as creating “winners in the long run” in preparingstudent-athletes for a post-athletic career, as well as coping with current demands to optimise development in an elite sporting career. For young student-athletes to successfully combine elite sport and study, it is important tohave a holistic perspective. Previous research in “dual careers” is based on the holistic perspective that describes the importance of a balance between sport, school and private life. The studies point out that the student-athlete has a challenging life situation to manage andit is important for the young student-athlete to feel good to be able to perform both in sportand study. The various research studies are based on and emphasize the sport, the sportenvironments and coaches. They put focus on the importance of the education and theimportance of the holistic perspective of sport, school and private life but do not go into depthhow the teacher's teaching or the student's way of learning should be designed for best results. This discourse analysis is defined as “mathematics at an elite sport secondary school”. The research question which shapes the given discourse reads: “What are the didactic perspectives in the student-athlete's educational environment, especially in mathematics teaching, seen as discourse?” The math teachers and the student-athletes are put into focus and the study investigates how they describe the math education at the RIG-school. The study is based onthe didactic perspective/teaching perspective in the student-athlete's educational environment. Data for the study was collected through interviews with math teachers and a questionnairefor student-athletes, at a RIG-school with approximately 60 student-athletes, during thespring of 2019.In the results of the analysis, the norms of the discourse, highly valued positions and dilemmaappear as five themes: “the important math-subject”, “the good student-athlete”, “thedilemma of the student-athlete's absence”, “strategies for support” and “the ambiguity of theform of the mathematics education”. These findings point to the fact that an ideal image of a successful student-athlete is clearly presented, that the math-subject is valued important and difficult based on its tradition and that the specific study form for mathematics education for student-athletes lacks a clear form. The model that is applied for the mathematics education at the RIG-school can be describedas teacher-led classroom education supplemented with various adaptations to facilitate the student-athletes' self-studies. In this study the discursive analysis also point out the success factors, which are summarized as the student-athletes' high responsibility, motivation and ability to plan and carry out self studies as well as the math teachers' various adaptations and support to facilitate the student athletes' self-studies.

Full textBased on the interlanguage hypothesis and with reference to skill learning and central concepts of connectionist language-acquisition theory, this study develops an explanatory model, with the help of which untutored acquisition of grammatical gender in German is shown to be a sequence of meta-individual developmental phases. The empirical evidence consists of linguistic data compiled from interviews with Italian, Portuguese, and Spanish foreign workers carried out within the framework of the ZISA- Cross-Sectional Study.
The acquisition process is promoted by a combination of two cognitive procedures, one analytic (restructuring) and the other reproductive (automation). Both contribute to the construction of a network of associative form-function mappings which, in the course of the process, assume the character of prefabricated linguistic elements or chunks, thus enabling automatic processing. Accordingly, the gender of a noun is not acquired separately as such, but rather as an integral component of an automatic form-function mapping.
Formula and routine are central concepts. They denote the norm-language (formula) and interlanguage (routine) chunks used by the learner and thereby the subsumed forms of the respective determiners, that is, gender markers. Their creation and substitution, as well as the sequence of their acquisition, are described and elucidated by means of cognitive mechanisms and psycholinguistic principles.
For the interlanguage routine in particular, but to some extent for the norm-language formula as well, it was possible to confirm the fundamental concept of the interlanguage hypotheses, according to which the learner sets up provisional hypotheses about the perceived elements and gradually approaches the form of the target language, albeit with the assistance of a concept of language acquisition that does not primarily center on any rule-defined morphology of the target language but rather on the phonetic surface-level form of concrete linguistic communication.
Against this background some key concepts of previous language-acquisition research, such as explicit/implicit, rules, chunks, simplification, omission, and over-generalization, are discussed and partially reassessed.

Full textDas NP-vollständige Problem k-SAT ist von zentraler Bedeutung in der theoretischen Informatik. In der Dissertation werden zufällige 4-SAT-Formeln mit > n^2 vielen Klauseln studiert. Diese Formeln sind mit hoher Wahrscheinlichkeit unerfüllbar. Hier wird erstmalig die Existenz eines Algorithmus gezeigt, der diese Unerfüllbarkeit effizient verifiziert. Hierfür wird die geringe Diskrepanz von Hypergrpahen und Multigraphen betrachtet. Der Schlüssel zu diesem Algorithmus liegt in der Kombination von spektralen Techniken mit Approximationsalgorithmen der klassischen kombinatorischen Optimierung. Der vorgestellte Algorithmus kann auf den effizienten Nachweis der Unerfüllbarkeit von Not-All-Equal-4-SAT-Formeln und die Nicht-2-Färbbarkeit von 4-uniformen Hypergraphen erweitert werden. Es wird ebenfalls eine Erweiterung der Hajos-Konstruktion nicht k-färbbarer Graphen auf nicht k-färbbare uniforme Hypergraphen angegeben

Full textUnder senare år har intresset för aktiemarknaden ökat allt mer, där aktörerna använder sig av en mängd olika sorters strategier, eller ingen alls. Vissa strategier kan anses vara mer komplicerade och tidskrävande medan andra är enklare att följa och förstå. Den Magiska Formeln och Piotroskis F-Score är två av de mer välkända investeringsstrategierna som båda har blivit utvecklade under 2000-talet och är relativt enkla att replikera. Syftet med denna studie är att jämföra prestationen för dessa två investeringsstrategier samt om de kan generera någon överavkastning i Danmark, Finland och Norge. Resultaten kommer dessutom jämföras med en tidigare studie gjord på den svenska marknaden, för att hitta eventuella skillnader mellan de nordiska länderna när investeringar skett enligt dessa strategier. Studiens resultat visade på att båda strategierna överträffar marknadens index flera gånger under tidsperioden samt att dess ackumulerade avkastning var högre än marknadens index mellan 2012–2021. Utav alla nordiska länder presterade portföljerna baserade på Den Magiska Formeln och Piotroskis F-Score bäst i Norge, och för samtliga tre länder presterade Piotroskis F-Score bäst av strategierna gällande ackumulerad avkastning under dessa nio år. Resultaten visade dock enbart statistiska skillnader mellan strategierna i Danmark och Norge. Samtidigt visar resultatet på statistiska skillnader för ackumulerad avkastning mellan länderna Norge och Sverige gällande portföljerna enligt Den Magiska Formeln under 2012–2020. Samma period visar även på statistiska skillnader mellan alla länder förutom Danmark och Finland gällande portföljerna enligt Piotroskis F-Score.

Full textBackground: The efficient market hypothesis is a widely spread concept throughout the financial sphere, but despite of its central roll it have had to withstand a lot of criticism. Anomalies have been identified which are a criticism against the markets efficiency. The interest of investment strategies has grown as of the emergence of the anomalies. Is it possible to generate abnormal returns through a pre-determined strategy, where the market inefficiency is exploited? We therefore find it interesting to study Greenblatt’s (2010) Magic Formula and if it is possible to generate abnormal returns by implementing the investment strategy. Purpose: The purpose of this study is to analyze whether the investment strategy Magic Formula can generate abnormal returns compared with the global stock market, and if it is possible to identify any performance differences between the European stock markets. Furthermore, the study aims to analyze how the re-balancing frequency and the time period effects returns from the Magic Formula. Methodology: To implement the study we have used a quantitative strategy with a deductive design. We have implemented a time series analysis where portfolios have been constructed and analyzed based on its return and risk. The results have been statistically tested through pairwise t-tests and regressions. The study is conducted on the European market from 2007-04-01 to 2017-04-01. Conclusion: 14 of the 18 Magic Formula portfolios have performed worse than the benchmark, according to annual average return and total return. Three of the 14 portfolios have had a significant lower return. The financial crisis affected the results greatly. If we excluded this time period only 11 portfolios performed worse, however without statistical support behind the results. Our results also suggest that a less frequent re-balancing of the portfolio generates higher return than a more frequent re-balancing.

Full textLet F ∈ Z[X1, . . . ,Xn] be a decomposable form, that is, a homogeneous polynomial of degree d which can be factored into linear forms over C. Denote by NF (m) the number of integer solutions to the inequality |F(x)| ≤ m and by VF (m) the volume of the set{x ∈ Rn : |F(x)| ≤ m}. In 2001, Thunder [19] proved a conjecture of W.M. Schmidt, stating that, under suitable finiteness conditions, one has NF (m) << mn/d where the implicit constant depends only on n and d. Further, he showed an asymptotic formula NF (m) = mn/dV (F) + OF (mn/(d+n−2)) where, however, the implicit constant depends on F. In subsequent papers, Thunder’s concern was to obtain a similar asymptotic formula, but with the upper bound of the error term |NF (m)−mn/dV (F)| depending only on n and d. In [20] and [22], hemanaged to prove that if gcd(n, d) = 1, the implicit constant in the error term can indeed be made depending only on n and d.The main objective of this thesis is to extend Thunder’s results to the p-adic setting. Namely, we are interested in solutions to the inequality |F(x)| · |F(x)|p1 . . . |F(x)|pr ≤ m in x = (x1, x2, . . . ,xn) ∈ Zn with gcd(x1, x2, . . . ,xn, p1 · · · pr) = 1. (5.4.3)where p1, . . . , pr are distinct primes and | · |p denotes the usual p-adic absolute value.Chapter 1 is devoted to the p-adic set-up of this problem and to the proofs of the auxiliary lemmas. Chapter 2 is devoted to extending Thunder’s results from [19]. In chapter 3, we show the effectivity of the condition under which the number of solutions of (5.4.3) is finite. Chapter 4 and chapter 5 generalize Thunder’s results from [20], [21] and [22]

Full textIn the last decade, the complexity of embedded systems has exploded and the usual industrial design flows do not suffice any more to propose reliable products while respecting time to market constrain. Thus, developing new design methodologies has become an imperative. The thesis aims at the improvement of the methodologies of conception of the embedded systems. It proposes a method for assisting the process of refinement along the design flow. The proposed approach splits the design flow into multiple-levels, in order to guide the designer in the design process, from the most abstract model down to a synthesizable model. Furthermore, by using formal techniques the method allows to check the preservation of functional correctness along the design flow

Full textThe HILECOP methodology has been developed for the formal design of critical complex digital systems; it therefore covers the entire design process, ranging from modeling to code generation for implementation on the hardware target (FPGA type electronic component), via formal validation. However, if the formal model, the Petri nets in this case, is inherently asynchronous, it is nevertheless executed synchronously on the target. In fact, the usual analysis approaches are not adapted in the sense that they construct state graphs that do not conform to the real state evolution within the target. In order to gain confidence in the validity of the results of the formal analysis, this work aims to capture the so-called non-functional characteristics, to reify them on the model and finally to consider their impact through the analysis.In other words, the aim is to improve the expressiveness of the model and the relevance of the analysis, considering aspects such as clock synchronization, effective parallelism, the risk of blocking induced by the expression of an event (condition) and a time window of occurrence, without omitting the management of exceptions.To deal with all these aspects, we have proposed a new method of analysis for extended generalized synchronous executed time Petri nets, transforming them into an analysable equivalent formalism. This formalism is associated with a formal semantics integrating all the particular aspects of the execution and dédicated state space construction algorithm: the Synchronous Behavior Graph.Our work has been applied to an industrial case, more precisely to the validation of the behavior of the digital part of a neuro-stimulator

Full textA software architecture describes its structure and behaviour using components and connectors, but their languages do not support the complete development of complex software systems, from architectural design to executable code. Some formal development methods permit to refine a software specification to obtain another one closer to the implementation, or even code, but without taking into account the system architectural description. We propose to use a refinement, mechanism to transform the architectural description into a "classical" formal specification, already supported by tools allowing the development achievement. We develop a formal system - named ß -SPACE - to bring successive refinements into operation, leading from the starting architectural description (in π-SPACE, a software architecture description language based on a process algebra) to a formal specification (a set of abstract machines of the B method, which is supported by tools to help the formal development and the code generation) to make a formal development of the application possible, in the B method framework, while guaranteeing that each refinement step preserves the initial architectural properties. The formal definition of the refinement is based on the rewriting logic, in which the abstract architectural and the target specification elements are represented. This logic is also supported by a tool which permits to automate the transformations. Our approach of the architectural refinement differs from other existing methods, by being interested not only in the addition of details to the formal description, but also in the transformation of its control structure: the composition of components and connectors in the architecture is transformed to obtain a hierarchy of B abstract machines. We ensure the conservation of the interesting architectural properties. This is an original approach both concerning its architectural range, its formalisation and its connection with the classical formal methods

Full textThe development of correct formal specifications for systems and software begins with the analysis and understanding of client requirements. Between these requirements described in natural language and their specification defined in a specific formal language, a gap exists and makes the task of development more and more difficult to accomplish. We are facing two different worlds. This thesis aims to clarify and establish interactions between these two worlds and to evolve them together. By interaction, we mean all the links, exchanges and activities taking place between the different documents. Among these activities, we present the validation as a rigorous process that starts from the requirements analysis and continues throughout the development of their formal specification. As development progresses, choices are made and feedbacks from verification and validation tools can detect shortcomings in requirements as well as in the specification. The evolution of the two worlds is described via the introduction of a new requirement into an existing system and through the application of development patterns. These patterns manage both the requirements and their associated formal specifications ; they are elaborated from the description of the form of the requirements in the client document. They facilitate the task of development and help to avoid the risk of oversights. Whatever the choice, the proposed approach is guided by questions accompanying the evolution of the whole system and makes it possible to detect imperfections, omissions or ambiguities in the existing

Full textThe cuspidal automorphic representations of the linear group over the rationals are, in a certain sense, "the final objects" in the theory of automorphic forms. Among these, a distinguished subclass are the algebraic representations. The complexity of such a representation is measured by two numbers, its motivic weight w and its conductor N. It is then natural to try to make lists of automorphic algebraic representations with small conductor and small weight. Chenevier and his coauthors succeeded in making such lists for motivic weight up to 23 and conductor N=1. The next logical case to consider is that of conductor N=p, a single prime. The first main result of this thesis is an explicit list of all such representations with motivic weight up to 17 and conductor N=2; there are 10 of them. This result can be extended under the additional hypothesis of self-duality up to motivic weight 19. There are similar results for prime conductor up to 17 (in which the weight bound becomes lower as the conductor becomes higher). Making exhaustive lists of automorphic representations (up to a certain motivic weight and conductor) involves two steps: firstly find the "footprints" of the representations in question; secondly, prove that the list is complete. For the first step, we use the theory of Arthur, which allows for the construction of many relevant representations from classical modular forms. (First the classical object leads to a representation of an orthogonal or symplectic group, which can then be transferred to a general linear group.) For the second step, we use an analytic method known as the explicit formula of Riemann-Weil-Mestre. For small weight and conductor, the lower bound provided by the constructive method coincides with the upper bound provided by the explicit formula, and hence one has obtained a complete list of automorphic representations. Along Arthur's theory, the relevant transfer for this thesis is that of split orthogonal groups SO₂ₙ₊₁ to GL₂ₙ. Since the goal is to construct representations of GL₂ₙ with prime conductor, a precise understanding of the representations of SO₂ₙ₊₁ with prime conductor is required. This is where the local part of the thesis comes in. We are able to classify the irreducible, admissible, tempered representations of SO₂ₙ₊₁(F) of prime conductor, where F is a p-adic field. We are furthermore able to characterize such representations according to a conjecture of Gross (which is then proven in the given case). This is the second main result of this thesis

Full textThe main goal of this PhD thesis is the study of the cohomology ring of the complement of a reduced algebraic curve in the complex weighted projective plane whose irreducible components are all rational (possibly singular) curves. In particular, holomorphic (rational) representatives are found for the cohomology classes. In order to achieve our purpose one needs to develop an algebraic theory of curves on surfaces with quotient singularities and study techniques to compute some particularly useful invariants by means of embedded Q-resolutions

Full textWe present two arithmetic applications of James Arthur's endoscopic classification of the discrete automorphic spectrum for symplectic and orthogonal groups. The first one consists in removing the irreducibility assumption in a theorem of Richard Taylor describing the image of complex conjugations by p-adic Galois representations associated with regular, algebraic, essentially self-dual, cuspidal automorphic representations of GL_{2n+1} over a totally real number field. We also extend it to the case of representations of GL_{2n} whose multiplicative character is ''odd''. We use a p-adic deformation argument, more precisely we prove that on the eigenvarieties for symplectic and even orthogonal groups, there are ''many'' points corresponding to (quasi-)irreducible Galois representations. Arthur's endoscopic classification is used to define these Galois representations, and also to transfer self-dual automorphic representations of the general linear group to these classical groups. The second application concerns the explicit computation of dimensions of spaces of automorphic or modular forms. Our main contribution is an algorithm computing orbital integrals at torsion elements of an unramified p-adic classical group, for the unit of the unramified Hecke algebra. It allows to compute the geometric side in Arthur's trace formula, and thus the Euler characteristic of the discrete spectrum in level one. Arthur's endoscopic classification allows to analyse precisely this Euler characteristic, and deduce the dimensions of spaces of level one automorphic forms. The dimensions of spaces of vector-valued Siegel modular forms, which constitute a more classical problem, are easily derived

Full textThis thesis is devoted to symbolic methods for local resolution of linear differential systems with coefficients in K = C((x)), the field of Laurent series, on an effective field C. More specifically, we are interested in effective algorithms for formal reduction. During the reduction, we are led to introduce algebraic extensions of the field of coefficients K (algebraic extensions of C, ramification of the variable x) in order to obtain a finer structure. From an algorithmic point of view, it is preferable to delay as much as possible the introduction of these extensions. To this end, we developed a new algorithm for formal reduction that uses the ring of endomorphisms of the system, called "eigenring". Using the formal classification given by Balser-Jurkat-Lutz, we deduce the structure of the eigenring of an indecomposable system. These theoretical results allow us to construct a decomposition on the base field K that separates the different exponential parts of the system and thus allows us to isolate, in indecomposable subsystems in K, the different algebraic extensions that can appear in order to treat them separately. In a second part, we are interested in Miyake’s algorithm for formal reduction. This algorithm is based on the computation of the Volevic weight and numbers of the valuation matrix of the system. We provide interpretations in graph theory and tropical algebra of the Volevic weight and numbers, and thus obtain practically efficient methods using linear programming. This completes a fundamental step in the Miyake reduction algorithm. These different algorithms are implemented as libraries for the computer algebra software Maple. Finally, we present a discussion on the performance of the reduction algorithm using the eigenring as well as a comparison in terms of timing between our implementation of Miyake’s reduction algorithm by linear programming and the algorithms of Barkatou and Pflügel

Full textWe study the notion of quasiperiodicity, introduced by Apostolico and Ehrenfeucht at the beginning of the 1990's, then extended to infinite words by Solomon Marcus at the beginning of the 2000's. A (finite or infinite) word w is quasiperiodic if it can be covered by occurrences, possibly overlapping, of another finite word, call its quasiperiod. In 2006, Monteil and Marcus introduced a stronger notion: multi-scale quasiperiodicity, the property of having infinitely many quasiperiods.First we study quasiperiodicity of two-dimensional infinite words. We show that, by contrast with the one-dimensional case where quasiperiodicity do not force any property on infinite words, there exist quasiperiods q which force 2D q-quasiperiodic words to have zero entropy. We also show that multi-scale quasiperiodicity in two dimension force the existence of uniform frequencies for factors.Then we give results on infinite words in one dimension. Most notably we give a method to determine the quasiperiods of an infinite words from its square and special factors. We show that the family of periodic words and standard Sturmian words are characterizable in terms of multi-scale quasiperiodicity
