The objective of this thesis is to develop probabilistic methods to perform nonlinear transient analysis in civil engineering applications. The manuscript is divided into two parts. For large-dimensional structures subject to coherent random loads, an asymptotic expansion-based method is used to improve linear evolutionary spectral analysis. Then, this method is extended to equivalent statistical linearization by a multiple timescales approach. The second part of the thesis is focused on small-dimensional systems. It explores the solution of the Fokker-Planck equation with the smoothed particle hydrodynamics method. This meshless Lagrangian method particularly ensures the conservation and the positivity of the probability field. The accuracy and efficiency of both approaches are compared with Monte-Carlo simulations. [less ▲]

A novel thermotolerant strain Acetobacter senegalensis sp. nov. (CWBI-B418(T)) isolated in Senegal from mango fruit, previously freeze-dried and conserved at 4 degrees C under vacuum packaging was successfully rehydrated into an acetifying medium. It was used as an inoculum culture and then applied into a new pilot plant scale acetifier (300 L) for vinegar production. This latter was specifically designed to produce a high volume and quality of vinegar in Sub-Saharan Africa at fermentation temperature of 35 degrees C. Several semi-continuous cycles of acetic acid fermentations were carried out. The behaviour of substrate and product concentrations, population of bacteria into the reactor was analysed as well as the evolution of acidity, acetification rates and stoichiometric yields. Operation with this novel bioreactor allowed achieving 8% (v/v) of acetic acid concentration at 35 degrees C. (C) 2007 Elsevier Ltd. All rights reserved. [less ▲]

An exceptionally well-preserved new acanthothoracid (placoderm fish) presenting complete endocranium and skull roof, from Saudi Arabia (Qasr Limestone Member, Jauf Formation), Early Devonian in age, is described as Arabosteus variabilis n. gen. n. sp. Compared to other Acanthothoraci, the new taxon exhibits a skull roof variable in its dermal plate distribution (e.g. a supernumerary plate: the posterior central plate) and sensory line pattern. Even the different specimens of this taxon show such variability between them. Arabosteus variabilis enlarges the scope of our knowledge of Acanthothoraci and Placodermi in general. Traditionally, the Arthrodira, one of the historically earliest described groups, provide the standard reference model for the placoderm skull roof pattern. The interpretation of the acanthothoracid skull roof pattern of the Saudi taxon from an arthrodiran model and the establishment of homologies is impossible to resolve unless based on prior assumptions (e.g. hypothesis of fragmentation or fusion for the paranuchal plate complex). The lateral line system of A. variabilis is unstable (e.g. presence or absence of the postmarginal sensory line canal) making it ambiguous to define bone homology and terminology. Consequently spatial distribution of skull roof plates has been retained for such a task with a minimal reference to the instable features of the sensory line groove distribution. [less ▲]

A special beam finite element is developed in order to study the behaviour of steel structures made of thin-walled members. The displacement field of a classical beam element is completed in order to allow the modelling of any in-plane global behaviour of the beam (tension, compression, in-plane bending, in-plane column buckling) as well as the local buckling of the different walls of the profile. The element has been developed for bifurcation analysis (critical loads computation) and for non linear analysis. Some results obtained on the modelling of an I-section with thin web are presented.

We show that the parameter space of axion-like particles can be severly constrained using high-precision measurements of quasar polarisations. Robust limits are derived from the measured bounds on optical circular polarisation and from the distribution of linear polarisations of quasars. As an outlook, this technique can be improved by the observation of objects located behind clusters of galaxies, using upcoming space-borne X-ray polarimeters. [less ▲]

After a brief introduction on the proposed policy instruments approach, the main funding mechanisms used in Belgium are identified, with the corresponding amounts (most of which are not publicised and have been obtained through our researches). Then, using (mainly financial) policy instruments as indicators, this paper tries to reconstruct some policies and to changes taking place. Three main questions will be considered. Focusing on the links that are (re)established between financing and security/law and order policies, can we consider that security, as under Napoleonic times, is ranking high among political priorities and, if so, how is this implemented through policy instruments and more particularly financial ones? The question on ‘how to finance a humanist (i.e. free thinker) organisation in a scheme devised for religious communities?’ is then tackled. Eventually, a possible change from an “offer” to a “demand” policy is discussed. [less ▲]

A new inorganic-organic hybrid material, known as ceramer, has been prepared by the sol-gel process. α,ω-Hydroxyl poly(ε-caprolactone) (PCL) has been used as an organic reagent, as such or after conversion of the hydroxyl end-groups into triethoxysilane end-groups. The novelty has to be found in the biocompatibility and biodegradability of the organic constitutive component. Since the hydroxyl end-groups of PCL are less reactive than the triethoxysilane counterparts, the preliminary reaction of the hydroxyl end-groups with 3-isocyanatopropyltriethoxysilane is recommended for decreasing the gelation time and the amount of PCL extractable from the final hybrid material. In this respect, it has been observed that the amount of PCL incorporated into the network is limited by the early vitrification of the reactive system. This drawback can be alleviated by curing the sample at a high enough temperature (100°C). TEM observations have shown that the organic and inorganic phases are intimately mixed when the weight composition in SiO2 and PCL is close to 50%. [less ▲]

Well defined poly[styrene-b-butadiene-b-styrene] block copolymers (SBS) end-capped with poly(t-butyl methacrylate) (PtBMA) and poly(methacrylic acid) (PMA) outer blocks, respectively, have been synthesized by the sequential anionic polymerization of butadiene, styrene and tBMA, followed by the selective hydrolysis of the PtBMA blocks into the corresponding PMA blocks. The structure-property relationships of these new thermoplastic elastomers have been investigated, with a special emphasis on the effect of the ester or acid outer blocks on the bulk properties. As a rule, tensile strength is improved by increasing the length of the ester or acid outer blocks from 0 to 140 methacrylic units. Dipole-dipole intermolecular interaction of the PtBMA blocks and hydrogen bonding of the PMA blocks may account for enhanced mechanical properties. However, too high a degree of strong intermolecular interactions can constitute a deterrent to good phase separation. This is supported by morphological observations and loss in tensile properties when the relative content of the ester or acid outer blocks exceeds some critical value. In the case of a high acid content, DSC analysis shows two thermal transitions at -70 ??C and 230 ??C for PBD and PMA blocks, respectively. [less ▲]
