Résumé :
Abstract The present paper addresses the problem of extracting indicial response functions from solutions of the Navier-Stokes equations. Two approaches are considered. In the first, the indicial response is computed directly by modifying the local grid velocity to reflect the step change in plunge velocity. The computed data are then fitted using an assumed form for the response function and numerical optimisation techniques. In the second (indirect) approach, the general form of the lift transfer operator is determined analytically from the functional form of the assumed response. Using the lift transfer operator explicit solutions of the in-phase and quadrature components of the normal force time history can be obtained. The unknown coefficients in the response function are then extracted from computed data for harmonic motion by fitting the time history using the explicit solution. Computed response functions are presented for a range of Mach numbers and are compared with analytical results and indicial models currently used within the rotorcraft community. For the cases considered there is no significant difference between the response functions determined using the direct or indirect approach. Comparison of the computed results with existing models suggests that generalisation of the response to step changes in incidence using a two-pole approximation of the circulatory response together with the Prandtl-Glauert factor is not possible. However, comparison with higher order semi-empirical models is much improved, providing some justification for the use of such models. In addition to these observations, the extracted response functions suggest improvements to piston theory to account for thickness effects. The proposed modification of piston theory is based upon properties of the static pressure distribution and so can be used in conjunction with both CFD and experimental data.

Résumé :
Many physical phenomena give rise to mathematical models in terms of fractal, non-differentiable functions. The paper introduces a broad generalization of the derivative in terms of the maximal modulus of continuity of the primitive function. These derivatives are called indicial derivatives. As an application, the indicial derivatives are used to characterize the nowhere monotonous functions. Furthermore, the non-differentiability set of such derivatives is proven to be of measure zero. As a second application, the indicial derivative is used in the proof of the Lebesgue differentiation theorem. Finally, the connection with the fractional velocities is demonstrated.

Résumé :
An aeroelastic formulation of 2D lifting surfaces in an incompressible flow field via the use of aerodynamic indicial functions is presented. The approach carried out in time and frequency domains yields the proper aerodynamic loads necessary to the study of the subcritical aeroelastic response and flutter of lifting surfaces, respectively. The expressions of the unsteady lift and aerodynamic twist moment in the frequency domain are given in terms of the Theodorsen’s function, while in the time domain, these are obtained directly with the help of the Wagner’s function. Closed form expressions of unsteady aerodynamic derivatives, helpful in an unified approach of response and flutter analyses, and results related to aeroelastic response to gust and blast loads are supplied. In this context, a novel representation of the aeroelastic response in the phase - space was supplied and pertinent conclusions on the implications of some basic parameters have been outlined.

Résumé :
A micro air vehicle (MAV) is a class of miniature unmanned aerial vehicles that has a size restriction and may be autonomous. Fixed-wing MAVs are very attractive for outdoor surveillance missions since they generally offer better payload and endurance capabilities than rotorcraft or flapping-wing vehicles of equal size. This research paper describes the methodology applying indicial function theory and artificial neural networks for identification of aerodynamic derivatives for fixed-wing MAV. The formulation herein proposed extends well- known aerodynamic theories, which are limited to thin aerofoils in incompressible flow, to strake wing planforms. Using results from dynamic water tunnel tests and indicial functions approach allowed to identify MAV aerodynamic derivatives. The experiments were conducted in a water tunnel in the course of dynamic tests of periodic oscillatory motion. The tests program range was set at high angles of attack and a wide scope of reduced frequencies of angular movements. Due to a built-in propeller, the model’s structure test program was repeated for a turned-on propelled drive system. As a result of these studies, unsteady aerodynamics characteristics and aerodynamic derivatives of the micro-aircraft were identified as functions of state parameters. At the Warsaw University of Technology and the Air Force Institute of Technology, a “Bee” fixed wings micro aerial vehicle with an innovative strake-wing outline and a propeller placed in the wing gap was worked. This article is devoted to the problems of identification of aerodynamic derivatives of this micro-aircraft. The result of this research was the identification of the aerodynamic derivatives of the fixed wing MAV “Bee” as non-linear functions of the angle of attack, and reduced frequency. The identification was carried out using the indicial function approach.

Résumé :
We investigated the effect of locally altered blood pressure on the remodeling processes of the cells and extracellular matrices of the splenic and ileal arteries and used an indicial function approach to quantitatively analyze the relationship between the altered blood pressure and the remodeling processes. Blood pressure in these arteries was locally modulated by constricting the aorta at a location between the celiac and mesenteric bifurcations, resulting in a higher blood pressure at the splenic arteries then at the ileal arteries, After the pressure changes, the cross-sectional areas and the fractions of the cells and extracellular matrices of the splenic and ileal arteries were examined by electron microscopy at 2, 6, 10, 20, and 30 days. We found that both arteries remodeled, but the splenic arteries (higher blood pressure) remodeled more rapidly and to a larger degree than the ileal arteries (lower pressure compared with the splenic arteries) of the same animal. To verify whether an identical change in the blood pressure at the splenic and ileal arteries leads to the same remodeling process in these arteries, we created another model by constricting the aorta at a location between the mesenteric and renal bifurcations, resulting in hypertension of the same level at both splenic and ileal arteries. We found that the remodeling processes of the cells and matrices were almost identical in the arteries with similar changes in blood pressure. Thus we conclude that the remodeling processes of cells and matrices of the splenic and ileal arteries are dependent on the local blood pressure in aorta constriction-induced hypertension, and the indicial analysis is a useful approach in the description of the relationship between the blood pressure and the arterial remodeling processes.

Résumé :
The goal of this study is to quantitatively describe the remodeling of the zero-stress state of the femoral artery in flow overload. Increased blood flow, approximately as a unit step change, was imposed on the femoral artery by making an arteriovenous (a-v) fistula with the epigastric vein. The a-v fistula was created in the right leg of 36 rats, which were divided equally into six groups (2 days and 1, 2, 4, 8, and 12 wk after the fistula). The vessels in the left leg were used as controls without operative trauma. The in vivo blood pressure, flow, and femoral outer diameter and the in vitro zero-stress state geometry were measured. The in vivo shear rate at the endothelial surface increased approximately as a step function by ∼83%, after 2 days, compared with the control artery. The arterial luminal and wall area significantly increased postsurgically from 0.15 ± 0.02 and 0.22 ± 0.02 mm2 to 0.28 ± 0.04 and 0.31 ± 0.05 mm2, respectively, after 12 wk. The wall thickness did not change significantly over time ( P > 0.1). The opening angle decreased to 82 ± 4.2 degrees postsurgically when compared with controls (102 ± 4.4) after 12 wk and correlated linearly with the thickness-to-radius ratio. Histological analysis revealed vascular smooth muscle cell growth. The remodeling data are expressed mathematically in terms of indicial functions, i.e., change of a particular feature of a blood vessel in response to a unit step change of blood flow. The indicial function approach provides a quantitative description of the remodeling process in the blood vessel wall.

Due to high levels of parasite resistance to different commercial active ingredients, new control alternatives are being studied, including the phytotherapy. These measures aim to search for helper methods in the control of parasitic diseases. However, there are many products available in the market and they have no scientific proof of its efficacy or possible side effects. The objective of this study was to evaluate the hematological and hepatic effects following administration of Neem pie (Azadirachta indica) in sheep. Three strengths of Neem cake was added to the mineral salt (1, 2 and 4 %) and administered during 126 days to 32 Lacaune sheep breed, divided into four groups: three groups for different treatments and a control were tested, which received mineral salt. Blood samples were taken every 21 days to perform the complete blood count, serum total plasma protein and fibrinogen and liver biochemical evaluation. In those same times, fecal samples were collected for quantification of eggs per gram of feces (EPG). Statistical differences between times and groups for several variables were observed, but without being related to the administration of Neem pie. The results of complete blood count, measurement of total plasma protein, fibrinogen and hepatic clinical biochemistry indicated that administration of Neem pie at concentrations of 1, 2 and 4%, does not interfere in hematological values , or on the integrity and liver function Lacaune sheep breed

Résumé :
La taille est une pratique culturale courante en arboriculture. Pourtant ses effets sur le rendement sont variables et peu prévisibles. Dans cette thèse, nous proposons d'étudier les effets de la taille sur la croissance végétative et la reproduction du manguier (Mangifera indica L.), à l'échelle de l'axe et de l’arbre, afin de mieux comprendre comment s’élabore le rendement suite à la taille. La taille a été caractérisée par deux facteurs : l’intensité de taille, définie à l’échelle de l’arbre comme la quantité de biomasse retirée par volume de canopée, et la sévérité de taille, définie à l’échelle de l’axe comme la profondeur de taille le long de l’axe. A l’échelle de l’axe, l’intensité et la sévérité de taille ont eu des effets sur l’occurrence, l’intensité et la dynamique de la croissance végétative. Nous avons aussi mis en évidence un rôle important du diamètre de l’axe taillé sur l’occurrence et l’intensité de la croissance végétative. La croissance végétative qui résulte de la taille a conduit à l’apparition de nouvelles populations d’axes dont les proportions dépendent de l’intensité de taille des arbres. La floraison de ces différentes populations d’axes diffère en termes d’occurrence, d’intensité et de dynamique et est affectée négativement par l’intensité et la sévérité de taille. A l’échelle de l’arbre, les rendements ont eu tendance à être plus faibles sur les arbres modérément et intensément taillés du fait d’une diminution du taux de floraison et/ou du poids moyen des fruits. Les arbres faiblement taillés ont eu des rendements similaires à ceux des arbres non taillés. Les effets de la taille sur la croissance végétative, aux niveaux structurel et temporel, ont été intégrés dans un modèle structure-fonction d'élaboration du rendement et de la qualité de la mangue, afin de caractériser les effets de la taille à l'échelle plus globale de l'arbre. Ce modèle nous a montré que le nombre d’axes et la surface foliaire retirés au moment de la taille sont largement compensés par la stimulation de la croissance végétative qui a suivi. L’intégration des effets de la taille sur la reproduction dans le modèle permettra de concevoir des itinéraires techniques intégrant les pratiques de taille afin de répondre aux problèmes agronomiques rencontrés sur le manguier, tels que les asynchronismes ou les irrégularités de production
Pruning is a common practice in tree fruit crops. However, its effects on the yield are variable and hardly predictable. In this thesis, we propose to study the effects of pruning on vegetative growth and reproduction for the mango tree (Mangifera indica L.), at the axis and at the tree scales, in order to better understand how fruit yield built-up following pruning. Pruning was characterized by two factors: pruning intensity, defined at the tree scale as the amount of fresh biomass removed per unit volume of canopy, and pruning severity, defined at the axis scale as the depth of pruning along the axis. At the axis scale, pruning intensity and severity had an effect on the occurrence, intensity and dynamics of vegetative growth. We also highlighted a major role of the diameter of the pruned axis on the occurrence and intensity of vegetative growth. The vegetative growth which results from pruning led to the emergence of new populations of axes whose proportions depend on pruning intensity. Flowering of these different populations of axes differ in terms of occurrence, intensity and dynamics and was affected negatively by pruning intensity and severity. At the tree scale, yields tended to be lower on moderately and intensively pruned trees as a result of a decrease of flowering rate and/or average weight of fruits. Lightly pruned trees had similar yields compared to unpruned trees. The effects of pruning on the vegetative growth, at the structural and temporal levels, were integrated in a functional-structural model of fruit yield and quality build-up. The model has shown that the number of axes and the leaf area removed at the pruning time were widely compensated by the vegetative growth stimulation that followed. The integration of the effects of pruning on reproduction will allow developing crop management techniques integrating pruning techniques in order to respond to agronomic issues related to mango tree as asynchronisms and irregular bearing

Résumé :
Within the general framework of risk management, the vulnerability of flexible bridges under wind action is addressed. Particular attention is paid to the risk of aeroelastic instabilities and buffeting oscillations in presence of self-excited phenomena. A computational framework based on semi-empirical cross-sectional models for the wind loading and on the three-dimensional finite-element discretization of the structure is developed. This represents a basic tool for assessing wind risk and it is used to obtain some results in the understanding of bridge behaviour under wind storms and in the comparison of different design solutions. A time-domain model for unsteady wind loading is derived as a development of indicial function load models. Some inaccuracy issues of literature models are solved and the consistency with the quasi-steady limit is ensured. A numerical procedure for identifying the load model coefficients from wind tunnel experimental data in such a way that the reliability of the measured quantities is accounted for is proposed, implemented, and validated. Analyses including structural nonlinearities and damping devices are made possible by the developed time-domain methods. The effects on aeroelastic stability and buffeting response of along-span wind coherence, mean deformations, and load and structural nonlinearities are quantified. Finally, mitigation strategies against aeroelastic instability and excessive buffeting oscillations are discussed. A risk-based comparison of some possible solutions is performed in the special case of a suspension bridge. Crossed hangers, secondary cables with opposed curvature, and tuned mass control devices are considered. The results, rendered in terms of yearly probability of collapse and expected number of days of closure to traffic, easily allow a cost-benefit analysis for deciding among different designs. Interesting results are obtained from the simulation of bridges controlled by tuned mass devices.

Piriformospora indica is a mutualistic endophyte with a broad host range and application potential in agriculture. Mutualistic microbes are able to produce effector proteins to interfere plant physiology for faciliting symbiosis with plants. In consideration of P. indica’s broad host-range, studies of P. indica effector proteins can establish a model for endophyte symbiosis with plants. This study focuses on functional characterization of effector proteins. According to lab’s previous studies, we already screen out two P. indica’s effector genes, PIIN_09643 and PIIN_11103 by bioinformatics approaches. We established overexpression lines of Chinese cabbage hairy root system and transgenic Arabidopsis thaliana. We also do agroinfiltrantion for transient overespression in Chinese cabbage leaves to confirm suppression of salicylic acid signal transduction. To investigate effectors function, we establish cDNA library to undertake yeast two-hybrid screening experiment. We found B. rapa’s Arabinogalactan protein 4 (AGP4) would interact with PIIN_11103. Arabinogalactan proteins are highy glycosylated glycoproteins mostly localized on plasma membrane, involved in cell proliferation, programmed cell death, pollen-tube development and somatic embryogenesis. This study found that BrAGP4 localized on plasma membrane and chloroplast envelope, and confirmed interaction of BrAGP4 and PIIN_11103 by BiFC. To characterize BrAGP4, we treated Chinese cabbage with AGPs inhibitor, found the inhibitory effects on root hair development but up-regulateing of auxin-relaed gene expressions. We also found that AGPs play a critical role in symbiosis process of P. indica and Chinese cabbage.

Piriformospora indica, an endophytic root-colonizing fungus, interacts with various plants species. From our previous researches, Chinese cabbage root colonization by P. indica results in an increase in plant growth, root propagation and adaptation to abiotic stress. Although P. indica has been reported to colonize and cause various beneficial function on plants, little is known about its early colonizeal mechanism. Previously, we screened several putative effector genes of P. indica by the bioinformatics screening system established from previous researchers. Further to characterize the function of P. indica effector proteins, four candidate genes PIIN_04020, PIIN_04363, PIIN_07152 and PIIN_08445 were chosen to establish Chinese cabbage transgenic hairy-root system、transgenic Arabidopsis thaliana for further investigation. Yeast two hybrid screening were used to screen the target interacting proteins against the effector proteins. B. rapa’s copper chaperone (CCH) against PIIN_04363 and glutathione S-transferase U24 (GSTU24) against PIIN_07152 were found. In this study, we found that PIIN_04363 gene expression was upregulated in the early colonized stages. Transgenic hairy-root system and transgenic Arabidopsis thaliana showed that PIIN_04363 suppress the expression level of SA pathway marker gene, PR-1 and cause a promotion of colonization efficiency. PIIN_07152 enhances the expression level of JA pathway marker genes, LOX2 and VSP2. Redox status relative genes DHAR and MDAR are also upregulated. From the observation of 7days-old transgenic Arabidopsis thaliana, the growth rate of PIIN_07152 OE was retard. It suggests that it is caused by the up-regulation of JA pathway. On the other hand, 7days-old transgenic Arabidopsis thaliana of PIIN_08445 OE show the higher growth rate in seedling stage, suggesting the effects of the up-regulation of auxin-related genes.

Piriformospora indica (P. indica) is a new root endophytic fungus belonging to the Hymenomycetes of the Basidiomycota. P. indica interacts with the roots of various mono- and dicotyledonous plants, showing the positive effect on biomass production. In addition to this growth promoting effect, P. indica also has the potential to induce resistance to fungal disease and to increase the antioxidative activities of plants. After the colonization of P. indica, plant becomes more tolerance to salt and drought. In this study, we used Chinese cabbage (Brassica campestris subsp. chinensis L.) for colonization with P. indica. After colonization for 7 days, six genes expression level of glutathione-S-transferase parC (BcGSTU), aux resistant 1 (BcAUX1) , efflux carrier, (BcPIN3), V-type proton ATPase (BcV-ATPase), expansin A17 (BcEXPA17),and root hair defective 4 (BcRHD4) were up-regulated and we have constructed above genes in pCAMBIA1300-35S-nos vector and tend to investigate gene function of the overexpressing cabbages. In glutathione assay, we found out the concentration of glutathione increased especially in leaves when Chinese cabbage colonized with P. indica. According to this result, we studied the tolerance Chinese cabbage colonized with P. indica under different stress. The results show that Chinese cabbage colonized with P. indica reduced the concentration of hydrogen peroxidase under NaCl stress indicated P. indica could enhance the salt tolerance of Chinese cabbage. We overexpressed these six gene in Arabidopsis and found out these gene could up-regulate the glutathione content and promote the growth of laterial roots, root length, and biomass. 35S::BcRHD4 could promote root hiars and 35S::BcGSTU could against the salt stress and drought sress. We figured out that glutathione play a role in plant growth and tolerance by P. indica colonized with Chinese cabbage.

Given its potent impact, the parties often disagree over which language (or languages) should apply where the clause is silent. This chapter considers the tools available to an arbitral tribunal to identify the language of the arbitration and to maintain the applicable language of the proceedings, while affording the parties flexibility in how they present their cases and ensuring that the matter proceeds efficiently. As with all discretions, this exercise must be carried out properly and fairly. In reaching their decisions, tribunals should not be confined by strict presumptions or priorities; they must assess all of the available indicia, weighing each element in the balance.

Résumé :
This chapter explores whether the concept of American exceptionalism applies to the discourse and conduct of community supervision in its main variant—probation—when comparing the United States with Europe. Community supervision in the United States does not serve merely as a stand-alone punishment. It functions frequently as a much-less-acknowledged “front door” to incarceration due to failures in its conduct. It is often used after incarceration terms or as an “elastic frame” in which additional punishments—such as economic sanctions, liberty restrictions, and coerced treatment—can be levied. This chapter's approach is to compare US and European probation through the use of five indicia, or “markers,” to gauge the penal scope and shape of probation. The markers provide criteria to assess the liberty restrictions imposed on offenders.

Résumé :
This article deals with the new generation of proper Mach dependent exponential approximations of the indicial aerodynamic functions toward the aeroelastic formulation of 2-D lifting surface in the subsonic compressible flow. The indicial lift response is a useful starting point in the development of a general time-domain unsteady aerodynamic theory. By definition, an indicial function is the response to a disturbance that is applied instantaneously at time zero and held constant thereafter; that is a disturbance given by a step function. If the indicial response is known, then the unsteady loads to arbitrary changes in angle of attack can be obtained through the superposition of indicial responses using Duhamel’s integral. The indicial functions have been used to modify the circulatory part of the lifting force and pitching moment in unsteady compressible aerodynamic models. The coefficients of the approximation are obtained with an indirect approach by relating numerical results obtained for oscillating airfoil in the frequency domain back into the time domain. compressible and supersonic flight speed regimes. Exponential approximations of the subsonic compressible indicial functions in the existing research works are available only in limited Mach numbers (M = 0.5, 0.6, 0.7, 0.8). In the present study, a novel exponential approximation is developed which represent the coefficients of approximations as functions of Mach number (0.5 < M < 0.8).

Résumé :
This paper provides aerodynamic indicial functions obtained through a discrete vortex computational fluid dynamics method for two-dimensional geometries, including two canonical sections, rectangular and elliptical shapes, and the Great Belt Bridge cross section. This methodology enables one to determine the unsteady lift and aerodynamic moment necessary in aeroelastic analysis of flexible bodies including flutter and vortex induced vibration. The predictions were obtained using an unsteady viscous flow solver, DVMFLOW, developed by COWI. The indicial functions developed have two exponential groups which parameters have been obtained using a nonlinear least square method. The numerical investigations show significant flow separation for the presented sections and an enhanced dynamic stall region at the initiation of a transient leading to higher values in the lift coefficient response. Vortex shedding frequency was also determined and the results are compared with other studies in the literature.

Résumé :
The unsteady lift for incompressible starting flow of a flat plate at high angle of attack involves a repeatable three-phase variation: (a) initial lift drop, (b) a Wagner type lift increase enhanced by leading edge vortex and (c) a lift drop due to a lift-decreasing trailing edge vortex spiral induced by the leading edge vortex convected to the trailing edge. For compressible starting flow at small angle of attack, it is well known that the lift experiences an initial drop due to piston effect and then a Wagner type lift increase enhanced by compressibility. The third phase has not been reported in the past. In this paper we consider subsonic, transonic and supersonic starting flow at high angle of attack. Numerical computation using computational fluid dynamics is used to compute the flow and lift behavior is explained using existing theories. It is found that, when the angle of attack is 20 degrees, we still observe the three-phase lift variation for Mach number below 0.8. The second conclusion is that the lift during the Wagner type increase phase is a decreasing function of the Mach number, in contrast to what we know from piston and indicial function method for small angle of attack. Another important conclusion is, when the Mach number is high enough, say above 0.9, only two-phase variation is observed: (a) initial lift drop and (b) Wagner type lift increase. For supersonic starting flow the Wagner type lift increase is replaced by a linear increase.
