The present thesis deals with a development of linear algebra, geometry and analysis based on (Z_2)^n-superalgebras: associative unital algebras which are (Z_2)^n-graded (for some natural number n) and graded-commutative, i.e., satisfying ab = (-1)^<deg(a),deg(b)> ba, for all homogeneous elements a, b of respective degrees deg(a), deg(b) in (Z_2)^n, and < . , . > denoting the usual scalar product. This generalization widens the range of applications of supergeometry to many mathematical structures -- the algebra of quaternions H and more generally Clifford algebras, Deligne algebra of superdifferential forms, higher vector bundles ... -- and appears also in physics -- for describing anyons, paraparticles -- proving its worth and relevance. In this dissertation, we first focus on (Z_2)^n-superalgebra theory: we define and characterize the notions of trace, determinant and Berezinian of matrices over graded-commutative algebras. Special attention is given to the case of Clifford algebras, where our study gives a new approach to treat the classical problem of finding a “good” determinant for matrices with non-commuting (quaternionic) entries. Further, we undertake the study of (Z_2)^n-graded differenital geometry. Privileging the ringed space approach, we define (smooth) (Z_2)^n-supermanifolds modeling their algebras of functions on the (Z_2)^n-commutative algebra of formal power series in graded variables, and develop the theory along the lines of supergeometry. Notable results are: the graded Berezinian and its cohomological interpretation (essential to establish integration theory); the theorem of morphism, which states that a morphism of (Z_2)^n-supermanifolds can be recovered from its coordinate expression; an analogous of Batchelor-Gawedzki theorem for (Z_2)^n-supermanifolds.

Two laboratory studies were carried out to assess the behavior of the active palmar sweat glands in both an active and a passive coping situation. Stressor in study I was watching a distressing film, in study II mental arithmetic. Subjects were male students, 17 in experiment I, 20 in experiment II. Both experiments involved a 10-minute baseline phase, a 10-minute stress period, and a follow-up of 10 minutes. PSI was assessed at 90-sec intervals and averaged across phases, as were readings in SCL, SCR, heart rate, diastolic and systolic blood pressure. PSI could be determined in 16 subjects of each study. In both experiments PSI increased significantly from baseline to stress (p less than 0.1%) and decreased from stress to follow-up (p less than 0.1%), and thus proved to be the most sensitive indicator for stress. The interrater reliability for counting the number of active sweat glands was high when the area for evaluation was defined unambiguously. Since the assessment of the PSI does not require a sophisticated technology and is thus also applicable in field research, we suggest giving more consideration to this variable. [less ▲]

Rule of law, whose core is „the access to an independent judiciary and judicial review”, fulfills in EU external policy two functions. Firstly, according to the art. 21 of TEU, all EU external actions have to be subdued to the rule of law. Secondly, promoting and consolidating the rule of law is one the objectives of EU external action. In most constitutional systems, a wide margin of appreciation is left as regards to foreign policy and judicial review is considerably limited. In case of EU, the Court’s jurisdiction over EU external policy is differentiated and reflects the old pillar structure. The question which arises here is whether it can be accommodated with the disposition of the art. 2 of TEU, which states that the European Union which is a single legal entity „is founded on the value of rule of law”, and with the principle of EU external policy coherence.

Streszczenie. Praca zawiera opis, wypracowanej przez firmę Eaton, metodyki obliczeń obudów skrzyń biegów zastosowaną w procesie konstruowania wyrobów. Dla lepszego zrozumienia zagadnienia omówione zostały cechy charakterystyczne korpusów wraz z szeregiem wymagań jakim muszą one sprostać (funkcjonalnym, technologicznym, kosztowym). Opracowany proces analizy został maksymalnie ujednolicony i ma zastosowanie zarówno dla przekładni wysokiej jak i niskiej obciążalności. Przedstawiono opracowane wymagania wytrzymałościowe jakie stawia się nowoczesnym konstrukcjom obudów skrzyń biegów, bazując na przeprowadzonych testach w pojazdach i naszym doświadczeniu. Zaprezentowano, jako docelowe rozwiązanie, spójną metodę analizowania obudów, które wykorzystują nowoczesne oprogramowanie metody elementów skończonych – ANSYS, ANSYS Workbench i zdobytą, w czasie testów i procesach walidacji wielu produktów, wiedzę. Model obliczeniowy został bardzo dobrze zweryfikowany, bazuje na wynikach laboratoryjnych badań zmęczeniowych, przeprowadzonych na rzeczywistych produktach, a także rezultatach prób drogowych w rzeczywistych pojazdach. Stworzona metodyka przyczynia się do znacznego skrócenia procesu konstruowania i weryfikacji konstrukcji, ograniczając do minimum konieczność testowania obudów. [less ▲]
