Full textThe subject of this thesis is to examine the link between the State and armed force, a link which embodied by war-faring activity, in other words by military function, while focusing on an approach to sociopolitical and legal theories of the State. Military function is part of the general activity of the State and it is up to the military authority to exercise this function. In order to deal with the ways and means this function is exercised, it will be subject to intra-functional analysis (i.e. a study centered solely on the military function) as well as inter-functional analysis (i.e. a study of the military function in relation to the executive and legislative functions). Military function is not autonomous. It is one of the functions carried out by the executive power. The military function is unique in that it is not carried out by a military organ which is responsible for this specific task ̶ the existence of such an organ has always been refused ̶ but by a political power based on a decisional authority hinging on a technical authority carrying out military command. What is at stake is to avoid the setting up of a military organ capable of evolving into a military power, a risk which threatens both the political authority as well as the military authority itself
Labarthette, Davy. "Contrat et prévision : contribution à l’étude des fonctions du contrat." Pau, 2004. http://www.theses.fr/2004PAUU2006.
Full textThe contract as an act of prevision. The drawing-up of the contract plays and essential part of the agreement itself : it organises the action by forsight, and in doing so endows the contract with security by respectfully guaranteeing the execution of its anticipations. In as far as circumstances allow in modern private law, it is the function of the act which is the object of the present study. In this respect, it appears that the duty of prevision is fully assumed by the contract although, at the same time, it seems to be neglected by the general theory of contract. Today, the parties have the means to fight against personal weaknesses thanks to the use of purely voluntary mechanics. Certain negotiated procedures allow them to face outside risks equally in order to protect the permanence of the agreement. Their use reveals itself as indispensable as since positive law, which carries a rigid conception of time, does not systematically have the concern of safe guarding relationships. The theory of unforseeability which favorises their durability is not always admitted, despite resources of the required good faith. The act of God's theory is unreliable. Although the agreement allows for the setting-up of methods of survival as protection of the parties, they are nonetheless not always respected sufficiently

Full textThis thesis work aims to develop Lab-On-Chip systems embedding magnetic functions. Here we report a novel, unconventional technology based on a composite polymer approach to integrate arrays of magnetic micro traps in microsystems. The composite polymer i-PDMS, consisting in a polydimethylsiloxane (PDMS) matrix combined with carbonyl iron (Fe-C) particles, exhibit magnetic properties while preserving the possibility of using soft lithography. It also can be covalently bonded to glass or PDMS, answering the problem of heterogeneous integration of metal-based materials in polymeric systems. Also, i-PDMS microstructure can be controlled by applying a magnetic field during its curing process. Such polyvalent material displays tunable magnetic properties according its inner organization or the concentration in magnetic powders. The manuscript starts with a presentation of the state of the art regarding magnetophoretic functions in microsystems, especially the classical fabrication process involved. A second part will be dedicated to the characterization of the i-PDMS physical and morphological properties. A theoretical model is then developed using finite element simulations to estimate the magnetic force generated by such array of micro traps. The experimental measurements of the magnetic force using an atomic force microscope are then presented. Finally, the i-PDMS membranes performances are characterized when implemented in microfluidic devices

Full textMeasure of mechanic properties of soft tissues provides a quantitative information which allow us to differentiate soft and pathological biological tissues. This can be done by propagating shear waves in the studied medium and measuring local displacements which are linked to the medium elasticity. A theoretical study of shear waves propagation is presented. An analytical model describes displacements induced in a homogeneous medium. A numerical model describes displacements induced in an inhomogeneous medium. An experimental study using a single element imaging system is realized. Afterwards, this imaging system is replaced with a linear multi-elements array. The medium image is then reconstructed from radiofrequency signals acquired separately on the linear array elements. A compromise is then found between time experimentation and estimation quality of displacements

Full textThe aim of this thesis is to quantify the hazard of rock fall on a rock-shed structure, and thus able to integrate this structure into a system of detection and warning. For this type of problem, the inverse methods may allow a characterization (identification and location) of the effort sustained by the structure. These methods are widely used for structures like beams and plates under dynamic loads unknown. To resolve this problem, one of the most used approaches is to create transfer functions between impact point and measuring point on the structure experimentally or numerically, measure responses, and find the force history by deconvolution of the signal. It is known that this type of problem is "ill posed". To obtain a stable solution with physical sense, it must generally be used to stabilize either by filtering noise, or by conventional methods of regularization, such as that of Tikhonov. The problem of characterization of impacts on a structure becomes more complex when the impact location is unknown. To resolve this problem, we can use an approach based on the minimization of an objective function representing the error between measured and estimated responses at several points forming a grid on the structure. In the case of a real structure with complex boundary conditions, it is preferable to opt for an experimental approach. A series of tests on simple structures like beams and plates can control the parameters affecting the quality of the force location and identification. To recreate the characteristics of the structure and behavior, an application of the approach on reinforced concrete slab is most appropriate. By using transfer functions obtained experimentally and validated numerically, the location and identification of force history becomes possible. This study opens perspectives to extend the application of inverse methods to characterize the efforts of such breath generated by a flood or an explosion

Full textA wave can be exponentially localized in a disordered medium, due to interference effects. This Anderson localization phenomenon leads to a cancellation of the conductance of a quantum fluid in 1D. However, theoretical works pointed out that an electric field may reduce or cancel this localization. We study here the effect of a force on the localization of a 1D quantum matter wave. Since both Anderson localization of an expanding wave packet and the effect of disorder on the transport between two reservoirs have been studied in ultracold atom experiments, we focus on two systems, namely the diffusion, or the transmission, of a particle.In order to calculate the transmission, we generalize a transfer matrix formalism to the presence of a, possibly inhomogeneous, force. The case of a speckle disorder as used in ultracold atom experiments is dealt with using two other analytical approaches. Our main is result is that the force can be entirely taken into account by renormalising the length with a local mean free path of the particle. For white-noise disorder, the force leads to a weaker, algebraic localization, whereas full delocalization appears for a correlated disorder. We then focus on the diffusion of a particle, using a numerical approach. A transition of delocalization of the particle for strong forces is shed into light through a power law increase of its position, whose exponent increases with the force. Moreover, we show that localization is systematically destroyed in a correlated disorder

Full textThis study presents constitutional law as an ideal framework to analyze the foreign relations of the State. Through a double standpoint, it examines these relations from the State’s perspective and through the action of the empowered organs of the State. In this way, the study aims to highlight the institutional and normative specificities of State’s foreign relations. When the State establishes diplomatic and military relations at the outer-limits of its borders, it assumes a singular role compared to other political non-state unities. It performs a political function (fonction-fin), as defined by Charles EISENMANN, which belongs to the field of foreign relations. This political function is hold by the State in order to fulfill one basic need of the sovereign collectivity : to establish and to maintain “good relations” outside its boundaries – irrespective of the conflictual or cooperative nature of these relations. Because law and politics are intertwined, the function of foreign relations do not pre-define the distribution of powers within the State. Nevertheless, it exerts some influence on the constituent’s choices and on the practices of the empowered organs. At the interface between the State’s interior and exterior, constitutional analysis enables therefore to reexamine many elements usually taken as evident. This study assesses them and observe its effects. For example, it is possible to nuance the State’s monopoly on foreign relations and, through a historical perspective, to moderate the governmental concentration of the direction of foreign affairs

Full textThis work has focused on the study of factors that explain the functionals performances of the lower limbs of the elderly. In a first study we showed that the maximum power (Pmax) and its component called the optimal speed (Vopt) obtained during a test of force-velocity of the knee extensors, are important determinants of functional performance elderly evaluated on three tests: walking on 6m, sit to stand 5 times from a chair and climbing 5 stairs. The more a person has a high Pmax and Vopt, the more its performance during functional tests will be. In addition, Vopt is considered an indirect assessment of the percentage of fast fibers; subjects with the highest values of Vopt are best performers during functional tests. The second study measured and compared the electromyographic (EMG) activity of the quadriceps when tested for isometric maximum voluntary contraction (IMVC), determination of maximum power and functional tests mentioned above. Measurement of EMG signal during these tests was used to determine to what extent the type of task induced a maximum activation or not. Older people show a greater ability to activate their quadriceps muscles when tested for concentric contraction rather than isometric or eccentric contractions. Tests using the IMVC compared to tests for determining the power, sit-tostand and stairs climbing would not be the most appropriate tests to measure the maximum neuromuscular activation capacity in the elderly. From these results improved testing of the elderly and guidelines for rehabilitation are proposed

Full textPoetry is considered as the existencialact of linking the being to concrete and empirical realties, while questionning the abstraction of langage. Modern architecture bethought as te form / fonction formula, corresponds to this definition of poetics, because its concern is time and place. It does so, nevertheless, in classical terms or words. The thesis analyses this formula as set forth by its inventor, Louis H. Sullivan, and shows that his work participates to the myth of modernity. But, because it is fictional, myth is different from poetry, and is radically opposed to it. Whereas architecture taht builds the real and lived place, reaches the poetic being, an accomplishment which is but an answer to the old need for a shelter. Some crucial point of Le Corbusier's work are also questionned, where is theory and metaphors of modernity are a matter of myth, and therefore are but rhetorics of this construction of space which we inherited

Full textThe order Primates is composed of species whose morphologies, life history traits and behaviors are very diversified. The oldest representatives are dated about 65 million years. Because of this diversity, studies have focused on understanding the relationships between different parameters. Among the morphological structures studied, the basicranium, in particular the characters of the ear, have very often been considered in a phylogenetic perspective. Since the development of new acquisition techniques such as micro-tomography (μCT), new data are available. Thus, the interest for the morphology of the inner and middle ear, hitherto difficult to access, is growing. The structures of the ear are recognized to have a functional role, both for locomotion, in balance, and for hearing, through auditory sensitivities. Concerning this second function, there is a great variability between the different primate species, suggesting a relation with the socio-ecological parameters. The aim of this thesis was to quantify and understand the morphological variation of the auditory system in primates. The first step consisted in characterizing the morphological structures of the ear and their variations, in order to obtain quantified parameters and to relate them to auditory parameters. The second step was to identify covariations between the morphological structures of the ear and the different biotic and abiotic factors, defining the species in their environment. From these covariations, the third step was to propose prediction models for fossil species, for which only the morphology is available. Finally, the last step of this study was to estimate the correlations between the auditory sensitivities, the frequencies emitted during the vocalisations and the morphological characteristics related to the oral communication. A first result of this work, carried out on a macro-evolutionary scale, allowed us to characterize in 3 dimensions the internal structures of the ear, to quantify the variation within the order, and to highlight a new variable: the degree of pneumatisation. This quantification of pneumatisation, on a large taxonomic scale, shows that the shape diversity of the ear cavities is largely explained by the effect of body mass and phylogeny. Beyond this relationship, a strong pneumatization seems linked to a good perception of the low frequencies, which can be related to a type of habitat and a lifestyle. The second step allowed us to demonstrate a covariation between morphological variables describing ear structures and ecological variables describing life history traits and habitat. A predictive model could thus be established from these covariations based on current species and applied to a fossil species. Thus, Adapis parisiensis, an Eocene fossil primate, could be described as a folivorous and frugivorous, diurnal species, living in humid tropical forests, in a small to medium size group (up to 20 individuals), and was probably monogamous. These results confirm those of previous studies and also make it possible to propose original reconstructions, especially for behavior. Finally, the morphology of the ear, reflecting the auditory sensitivities, but also other cranial characters, indicate correlations with the vocal repertoire. Although these results are more prospective, they nevertheless allow to propose a type of communication for fossil species. This work has shown that ear morphology was a good proxy to reflect the relationships between species with their environments

Full textMost problems of physics and mechanics lead to partial differential equations. The many methods that exist are relatively low degree. In this thesis, we propose a method of very high degree. Our idea is to increase the order of interpolation function via a perturbation technique to avoid or reduce the difficulties caused by the high cost operations such as integrations. In dimension 1, the proposed technique is close to the P-version finite elements. At a basic level, approximates the solution by a power series of order p. In the case of a linear equation of order 2, the local resolution can build an element of degree, with two degrees of freedom per element. For nonlinear problems, a linearization of the problem by Newton's method is needed. Tests involving linear and nonlinear equations were used to validate the method and show that the technique has a similar convergence in the p-version finite elements. In dimension 2, the problem is discretized through reorganizing polynomials in homogeneous polynomials of degree k. After a definition of variables called principal and secondary combined with a vertical scanning field, the problem becomes a series of 1D problem. A collocation technique allows to take into account the boundary conditions and coupling conditions and determine the solution of the problem. The collocation technique coupled with the least-squares enabled to improve the initial results and has made more robust the perturbation technique

Full textFemoroacetabular impingement (FAI) is a pathomechanical process of the hip joint, which could lead to hip pain and functional disability. Aim of this thesis was to investigate hip muscle function in patients with a symptomatic FAI. Hip muscle function was first investigated before patients underwent any surgical treatment for managing FAI. It was shown that they present with reduced hip muscle strength (i.e., muscle weakness), probably due to hip muscle inhibition. Nevertheless, hip muscle weakness was not associated with exaggerated hip muscle fatigue. Hip muscle strength recovery was then evaluated in a series of patients after hip arthroscopy to treat FAI. These patients demonstrated a good recovery for all hip muscle groups, except for hip flexors. The case of a professional ice hockey player who underwent bilateral hip open surgeries for treating bilateral FAI was also documented. This report showed that iliotibial band dehiscence could occur after hip open surgery, thereby preventing hip abductor strength increase during rehabilitation and delaying the return to sport. In addition, the assessment of the rate of force development scaling factor for the hip muscles was evaluated in a group of healthy adults. This parameter seems to be promising for the evaluation of hip muscle inhibition. The testing protocol was feasible and reproducible for hip adductors, external rotators and flexors. Taken as a whole, these findings show that patients with symptomatic FAI demonstrate an impaired hip muscle function, which is however mainly resolved after surgical treatment

Full textFar from the oecumenical celebration and the negritudian idealization of pre-colonial africa on the one hand, and the worship of formal franch language made from writers of his generation on the other hand, kourouma elaborates a new and deliberately inconoclastic and novelistic aesthetics in his novels. Half-way between oral tradition and classical novel writing, kouroumian aesthetics is embeded in an enunciative problematic. If the ultimate goal of this study is the expression of high degree, our approch is double-sided : showing the influence of oral tradition on the novelist's writing through his excessive use of hyperbole in the narration ; showing, by the description of linguistic expressiveness mechanism, in general, how the essential concern of the quest for a discursive credibility is solved. Among other subjects, we deal here with the frame of kouroumian aesthetics, that is, the problem of linguistic interferences and peculiarities, the problem of synonyms, polysemy and lexical creation. Un other words, without pretending to be exhaustive, this linguistic and semantic study intends to answer the questions of expressive and affective syntax, of grammar and, above all, of psychological and socio-cultural conditions of enunciation

Full textThis research work treats the convective phenomena in transitory mode. More particularly, it identifies the convective exchange coefficient on a heated plane plate and placed in a rectangular channel. Two analytic models are discussed:The first model is based on the resolution of the heat propagation equation in a plate using the Green functions method. By this method the evolution of penetrating parietal flow in the fluid and the convective exchange coefficient are deduced in a rigorous way. We notice that this coefficient takes very significant values in the vicinity of t = 0 then decreases and tends towards a constant limit value in permanent mode near the values obtained from the correlations used in he literature. The second model is based on the resolution of the fluid energy equation in the case of a heat flow applied to the solid-fluid interface also by using the Green functions method. This original approach allows, by knowing the speed profile in the dynamic boundary layer, to determine the temperature profile in all the fluid and thus the temperatures and the thermal boundary layer. An experimental test bench permitted to identify the necessary limiting conditions for the two analytical models. In this test bench the plane plate is exposed on its lower face to a crenel of flow transmitted by conduction and penetrating in the fluid by the higher face without disturbing the flow. An Infra-red Camera is installed towards the plate in order to record the temperature profile on this face. To avoid modifying the thermal and dynamic boundary layers, no flow measurement system is installed on the higher face of the plate

Full textThis dissertation treats nominal patterns in Modem Hebrew (henceforth MH). In it, I explore the two following claims: 1)Words are built in Syntax. 2)The form of a word is indicative of its syntactic structure. It follows from the conjunction of the two claims that the form of a word is less arbitrary than it might seem, because it an be motivated by the syntactic structure of the word. Inversely, the (morpho-)syntactic structure of word can be detected through the examination of the form of that word. In the dissertation, I show several cases in which this approach to morphology is invalidated through its capacity to motivate the distribution of signifiants in the language. My main conclusion is that the form of a word, however arbitrary, is often not accidental: it can be motivated synchronically. The first part of the dissertation deals with exclusively phonological processes. I examine vocalic alternation between two different vowels or between a vowel and Ø (=syncope or epenthesis). The following three analytic chapters deal with different aspects of MH morpho-syntax. In chapter 4 I study unaffixed nouns and draw conclusions for Phase Theory chapter 5 examines the various suffixes of MH and the processes related to them. Finally, in the last chapter I turn to nouns that are related to verbs: participles, m-nouns, infinitives and agentives. In these chapters, homophony and allomorphy are shown to be non-arbitrary. These three chapters ail point to a non-trivial dependency between form (phonology) and function (syntactic structure). The dissertation thus lends support to (1&2) above

Full textThe form of a bone results from many genetic, developmental and adaptive processes. This study aims to work with the form in descriptive, comparative and functional approaches to highlight morpho-functional (evolutionary) patterns with a specific focus on islands. The feeding apparatus of Crocidura russula is a good example of a highly integrated structure particularly sensitive to selection pressures related to diet. Indeed, C. Russula is a generalist consumer whose spectrum of prey diversity and size is extremely varied. Morphometry currently offers methods, sliding-landmarks in 2D and 3D, to describe anatomical areas poorly studied because they posses few or no anatomical landmarks. This study showed that the form of these areas has, however, great descriptive potential at the specific and populationel levels. Moreover, this approach is capable of detecting a distinct functional signature that informs the selective pressures driving the observed variation in form

The aim of this thesis was to investigate muscular function and energetics in response to acute exercise, ischemia – reperfusion and endurance training in a mouse model of SCD, as well as identify the mechanisms involved in proton exchanges between muscle and blood.Sedentary and trained SCD mice were submitted to protocols of rest – stimulation – recovery and rest – ischemia – reperfusion during which muscular force and energetics (by magnetic resonance spectroscopy of phosphorus 31) were measured. Monocarboxylate transporter 1 (MCT1) haploinsufficient mice were also submitted to the stimulation protocol. Several muscles were sampled and permitted to analyze in vitro enzyme activities, content of proteins involved in pH regulation and some markers of oxidative stress.This thesis demonstrated that muscular function and energetics were impaired in SCD mice in response to both exercise and ischemia – reperfusion and that endurance training could alleviate some of these abnormalities, particularly acting on oxidative processes. We have also observed that MCT1 is involved in proton uptake by myocytes at rest, but its action is less important during exercise

Full textIn this document, we study efficient representations, in term of size, of a given semantic content. We first extend an equational specification of median forms from the domain of Boolean functions to that of lattice polynomials over distributive lattices, both domains that are crucial in artificial intelligence. This specification is sound and complete: it allows us to algebraically simplify median forms into median normal forms (MNF), that we define as minimal median formulas with respect to a structural ordering of expressions. We investigate related complexity issues and show that the problem of deciding if a formula is in MNF, that is, minimizing the median form of a monotone Boolean function, is in sigmaP, at the second level of the polynomial hierarchy; we show that this result holds for arbitrary Boolean functions as well. We then study other normal form systems (NFSs), thought of, more generally, as a set of stratified terms over a fixed sequence of connectives, such as (m, NOT) in the case of the MNF. For a fixed NFS A, the complexity of a Boolean function f with respect to A is the minimum of the sizes of terms in A that represent f. This induces a preordering of NFSs: an NFS A is polynomially as efficient as an NFS B if there is a polynomial P with nonnegative integer coefficients such that the complexity of any Boolean function f with respect to A is at most the value of P in the complexity of f with respect to B. We study monotonic NFSs, i.e., NFSs whose connectives are increasing or decreasing in each argument. We describe optimal monotonic NFSs, that are minimal with respect to the latter preorder. We show that they are all equivalent. We show that optimal monotonic NFSs are exactly those that use a single connective or one connective and the negation. Finally, we show that optimality does not depend on the arity of the connective

Full textIn the ancient Near East various stones were used for jewelry production. For the Bronze and Iron Age, in the Caucasus, Luristan and Levant many carnelian beads have been collected from the beginning of the archaeological activities till present days. Up to now, no specific study had been led on carnelian omaments. Using the methodologies developed in other cultural areas, we can question and compare the numerous carnelian ornaments from theses three regions. Beside the typological approach, the beads were inspected on from the technological point of view. We attempted to reconstruct the different steps of production. Also to compare the stone ornaments of the Bronze Age and beginning Iron Age with the collections from Egypt, Mesopotamia and the Indus valley allows to complete the interpretation and to determine possible origins of the raw material. It appears that in South Caucasus the perception of carnelian is different from Luristan and Levant. While in these two last societies the nature of the stone is as important as its aspects for magical, religious and prestigious beliefs, in South Caucasia, the red color comes first and the nature of the stone can be secondary. Chronologically we see a change in the use of the carnelian from the Bronze Age to the Iron Age periods, in these three different regions. If in South Caucasus the use of carnelian decreases compared to other materials, in the Levant it increases, while in Luristan its use seems to change. These results can be related to the political organization of these societies and to the long distance exchanges between these areas

Full textForm and function are linked of a fundamental level. Bones, for example, are clearly functionally important. They allow movement and, whilst supporting loads, also need to respond and resist to muscular forces. Indeed, bones are shaped by force and motion and thus, presumably intimately related to the movements executed, and thus also the lifestyle of a species. This is the background of this project where the origin and nature of phenotypic variation is studied in relation to phylogenetic constraints and mechanistic form-function relationships in the context of adaptations to specific ecological demands. To study this form-function relation I investigated the influence of different factors on the shape of the postcranial bones of mammals using 3D geometric morphometric methods and comparative approaches that take into account phylogeny. Moreover, I tried to infer the function and ecology of an extinct taxon. The results of this PhD show that many factors influence the morphology of the postcranial skeleton ranging from the body mass, over locomotor strategies, to more specialized behaviours such as grasping ability and shared ancestry. The results also highlight the difficulty in inferring function and ecology of extinct taxa, especially for species that have no extant relatives. Finally, our results shown that there is a relation between form and function, but that our understanding thereof remains hampered by a lack of quantitative data on the locomotor behaviour in the taxa under study
