A partir de deux ensembles d’initiatives qualifiées de « réparatrices » (essentiellement la réparation en milieu carcéral en Belgique et la réparation pénale chez les mineurs en France), nous proposons d’analyser les dernières recompositions de l’activité pénale en Belgique et en France. L’histoire du système pénal illustre l’impact des controverses qui l’entourent ainsi que le retentissement de thèmes contemporains (responsabilisation, incitation, accompagnement, procéduralisation…) sur les pratiques de ses divers intervenants. De nouveaux modes de régulations –normative, stratégique, identitaire- apparaissent et opèrent sur un ton neuf. Ce ton n’est plus celui du supplice, de l’enfermement ou du traitement, mais bien celui de la responsabilisation d’un individu fautif, capable de réparer son erreur. En outre, ces modes de régulation obéissent à des mécanismes qu’ils contribuent à produire. Quelle est la nature de leurs logiques ? Sont-elles compatibles ? Annoncent-elles la naissance d’un nouveau paradigme ? Que nous apprennent-elles quant à la légitimité de la violence (la peine) infligée par l’Etat ? [less ▲]

The gravitational lens phenomenon is briefly introduced. When several images of the same variable quasar are observed, a determination of the time delay, i.e. the difference in light travel time between these different images can lead to a determination of distances between the source, the lens and the observer and, thus, of the Hubble constant. These determinations are compared to the more classical ones based on standard candles (Cepheids and Type Ia Supernovae). [less ▲]

Recently, a first step towards a highly distributed IP-level topology discovery tool has been made with the introduction of the Doubletree algorithm. Doubletree is an efficient cooperative algorithm that allows the discovery of a large portion of nodes and links in the network while strongly reducing probing redundancy on nodes and destinations as well as the amount of probes sent. In this paper, we propose to reduce more strongly the load on destinations and, more essentially, the communication cost required for the cooperation by introducing a probing stopping rule based on CIDR address prefixes.

In ventilation systems, disturbing whistlings can occur at outlets. This whistling phenomenon belongs to the self-sustained tones class which can be produced when a low velocity flow impinges on a downstream obstacle. The coupling of the tones with acoustic resonances (so-called indirect feedback path) can promote high-level harmonic noises. This experimental study deals with the coupling of a jet-slot oscillator, modelling a ventilation outlet, with the flow supply duct resonances. The flow supply duct is damped by using various amounts of acoustic damping foam, and the effect of this damping on the sound production is studied. It is shown that for a jet exit/obstacle distance higher than 2.5 jet height (L/H>2.5), the tone’s frequency matches satisfactorily with frequencies predicted by a model describing favourable phase relationships for the occurrence of tones along the feedback loop. When the flow supply duct is resonant, it is noticeable that the tone’s frequency occurs at a duct resonance frequency which is close to the frequency described by this model. For lower values of L/H (slot closer to the jet exit), a better knowledge of the convection velocity behaviour along the vortices path could improve the tone’s frequency prediction. The use of damping foam within the flow supply duct prevents the occurrence of the tones’ coupling with a duct resonance, especially with high amounts of damping material, and dramatically reduces the emitted acoustic levels. For moderate amounts of damping material, the suppression of coupling occurs only for higher flow speeds, as the tone’s frequencies are higher and the damping material is then more efficient.

The next generation of infrared - sub mm space telescopes requires some reflectors with large dimensions and high quality. These ones, according to weight issues, are based on composite materials for which the behaviors at low temperatures are badly known. A holographic interferometry method for the verification and validation of this type of reflectors in a space environment is presented. It is based on a dynamic holographic camera observing a diffuser illuminated by the object beam coming from the reflecting surface. Photorefractive crystals being self-processing and reusable mediums, the measuring range of the holographic camera is increased with respect to other optical interferometric methods. The metrological certification of the whole system was realised by the measurement of a parabolic antenna with a 1.1 meter diameter, a known behavior and placed in a simulated space environment [less ▲]

A general procedure for the evaluation of the mechanical properties of structural joints, named “component method” [01], is now available from intensive research works at the European level. This procedure allows the analytical prediction of the resistance, but also of the stiffness and the deformation capacity, of structural joints under external forces (axial or shear forces, bending moments, …). In the present paper, timber joints with dowel fasteners are considered. Two components may be identified: the “dowel fastener in bending and shear” and the “timber member in embedding”. [less ▲]

Based on the Belgian soil map at 1/20,000, this digital map of Wallonia (DSMW) is composed of a cartographic database describing the soil characteristics of the region. Tool for a better soil management, this database will be integrated in a geographical information system where the soil layer could be used in relation with information concerning other aspects of land development. The different operations include : map drawing finalization of non edited sheets, creation of an image layer, vectorial capture of source objects, building up of the topology, characterization of the objects, geometrical corrections, creation of a continuous layer (edge-matching), creation of a homogeneous legend, integration in a geodatabase. The DSMW in figures corresponds to : 16,000 km2; 600,000 soil polygons delimited by 15 million intermediate points (vertex); 6,000 pedological symbols; 700MB. The advantages of this computerized cartographic database are continuity, legibility, accessibility and many possibilities of thematic analyses. [less ▲]

Many applications as corridors, railways tunnels or tube stations present a long room geometry. A fast and reliable modelling of such sound fields could be helpful for designers. In fact, the classical statistical theory based on the assumptions of diffuse sound field is not applicable in such cases because the reverberant sound energy along the room is not uniform. In this study, several models assuming diffuse reflections of sound by walls are used for predicting the reverberant sound field in long rooms. Two models based on a diffusion equation for the energy density (one numerical and one analytical based on an image approach for describing the sound reflection at the corridor extremity) are compared with a radiosity model, and with a ray tracing software. Predictions are compared in terms of sound attenuation and reverberation time with measured data. The long rooms considered in this study were two rectangular corridors of lengths 20.3m and 47.3m. All models overestimate the attenuation, reaching 6dB for the numerical diffusion based model. When a part of specular reflection (30%) is added in the ray tracing model, the predicted sound attenuation matches with the measured one: even in case of rough surfaces, specular reflections cannot be totally excluded. For reverberation time, the agreement between predictions and experiments is good with fewer than 15% of discrepancy. The best predictions of the reverberation time were given by the diffusion models, with discrepancy less than 2% for the numerical model. So, it could be concluded that it is difficult to find a prediction method which is consistent both in terms of steady state and sound decay for the acoustics of long halls. [less ▲]

The use of in-flight Oxygen Collection has shown to significantly improve space launcher performance. The conceptual approach followed by the Royal Military Academy of Brussels (RMA) has tried to widen the available design margins in order to reduce the required technological leap and limit the economical risk associated with such a development. The aim of the ESA-funded theoretical and experimental study on an air separation device is to demonstrate the possibility of performing efficient air distillation in a compact rotating column. An integration of the vehicle, propulsion system and separation unit designs is presented aiming to optimise the overall vehicle performance while keeping technological difficulty and system complexity at a reasonable level. Reference vehicles are presented in their specific mission profiles with an emphasis on TSTO’s. Different layouts of the internal energy and mass flowsheets have been studied and were compared in order to make best use of the refrigeration capacity of the hydrogen fuel running though the propulsion system during the first phase of the flight considering the separator as a classical distillation column. This analysis provides the requirements in terms of heat exchange capacity, compression ratios and number of so-called transfer units needed in the separator. Here, the system is intentionally kept simple, to limit complexity, but the analysis is thorough and accurate, including, for example, the effect of the presence of argon. Results for a supersonic carrier are presented. An analysis of the separation unit to reach those requirements has been performed. That includes internals, practical building with estimates of pressure drop, separation performance and flow limitation. The sizing of the separator bed is provided for a carrier plane showing that such on-board separator is indeed practical. [less ▲]

The rotifer Brachionus calyciflorus is a ubiquitous species that often dominates river zooplankton. It has been described as a species that selects its food mainly on the basis of the size of food particles and not on the basis of their taste. Nevertheless, experiments carried out with a green algae, 3,5 microns in diameter, showed that the ingestion rate of rotifers on DTAF (5-(4,6-dichlorotriazin-2-yl)aminofluorescein) stained algae is much lower than on untreated algae. The impact of all steps of the staining procedure was tested to determine the factor that elicits a negative selection against stained algae. Moreover, impact of algal abundance and light on selection was tested. Results clearly show the selection is triggered by chemical cues, DTAF itself inducing the strongest avoidance. Algal abundance influenced the degree of selectivity of rotifers; analysis of ingestion rate of treated and untreated algae throughout all treatments provide information on selection mechanisms and support the hypothesis that B. calyciflorus can detect chemical cues in the buccal funnel, even when feeding on small preys, and select its food accordingly.

Coccolithophores, among which Emiliania huxleyi (Ehux) is the most abundant and widespread species, are the dominant calcifying phytoplankton in the temperate zone of the world’s oceans. The continental margin in the Northern Bay of Biscay (North Atlantic Ocean) was visited in June 2004 during a multidisciplinary investigation of a late-spring bloom dominated by Ehux. Field sampling was assisted by daily transmission to the RV Belgica of remote sensing images, indicating the bloom development in the area. Primary production and calcification were measured by 14C incubations and zooplankton grazing experiments were performed. Vertical distributions of transparent exopolymer (TEP) concentration and bacterial density, as well as the bacterial production in surface waters, were also determined to elucidate the fate of biogenic carbonate production. The organic and inorganic carbon fluxes are evaluated in terms of relevant processes and discussed in relation with the DIC and nutrient dynamics. [less ▲]

We describe a new project aiming at measuring time delays for most known lensed quasars, from optical light curves obtained with five (almost) dedicated 1-2 m telescopes in the Northern and Southern hemispheres. The goal is to evaluate the Hubble constant H[SUB]0[/SUB] with a precision below 2%. We present here numerical simulations in order to define the optimal temporal sampling in our observations as a function of typical quasar variations, object visibility, and for a given accuracy on the individual photometric points. It is also emphasized that the ongoing effort to obtain deep imaging using both space and ground based facilities must be continued, as illustrated by the comparison of HST and VLT near-IR images of the `cloverleaf': H 1413+117.

A common assumption made in the performance assessment of a turbine engine for aircraft propulsion consists in restricting the data processing to steady-state data. This especially holds for on-board performance monitoring of a commercial aircraft which spends up to 90% of the time in cruise flight where such conditions are satisfied. The present contribution is intended to investigate the ability of a diagnosis method to process unsteady data rather than steady-state data. The aim of this unsteady approach is to strongly reduce the time and the efforts spent to obtain a reliable diagnosis. In order to assess the improvements in terms of diagnosis efficiency and engine operability, the resulting diagnostic method is tested for different degradations that can be expected on commercial turbofans. The results are also compared to those obtained from cruise flight steady-state data in order to balance the two approaches. [less ▲]

This paper deals with the filtering of harmless contingencies in voltage stability and security analyses. In many systems, a post-contingency load flow allows to identify the contingencies with severe impact on voltage stability, as causing either divergence or large voltage drops. However, for filtering purposes, accurate voltage drops need not be computed; linear estimates obtained from sensitivity formulas are appropriate. For a given contingency, the method used in this paper solves a sparse linear system to update the phase angles, assuming constant voltage magnitudes. Then, assuming constant active power flows in the branches, a second sparse system is solved to update the voltage magnitudes. This yields better accuracy than one full load flow iteration while retaining the sparse structure of a decoupled formulation. For contingency analysis, the incidents are filtered by comparing the voltage drops to a threshold. For secure power margin computations, the same procedure is used after stressing the system in the specified direction. The method has been tested on a real system where it has been found to combine simplicity of implementation, quality of filtering and computational efficiency. [less ▲]

We define, for an overlay built on top of an ad hoc network, a simple criterion for neighbourhood: two overlay nodes are neighbours if and only if there exists a path between them of at most R hops, and R is called the (overlay) neighbourhood range. A small R may result in a disconnected overlay, while an unnecessarily large R would generate extra control traffic. We are interested in the minimum R ensuring overlay connectivity, the so-called critical R. We derive a necessary and sufficient condition on R to achieve asymptotic connectivity of the overlay almost surely, i.e. connectivity with probability 1 when the number of overlay nodes tends to infinity, under the hypothesis that the underlying ad hoc network is itself asymptotically almost surely connected. This condition, though asymptotic, sheds some light on the relation linking the critical R to the number of nodes n, the normalized radio transmission range r and the overlay density D (i.e., the proportion of overlay nodes). This condition can be considered as an approximation when the number of nodes is large enough. Since r is considered as a function of n, we are able to study the impact of topology control mechanisms, by showing how the shape of this function impacts the critical R. [less ▲]

Using manual acoustic tracking our study quantified (1) the spatial distribution (2) the movement patterns and (3) the depth preference of adult whitefish in a small artificial lake of eastern Belgium were the species was introduced in 1978 for recreational fishing. From June to October 2004, n=6 C. lavaretus (LF 285-519 mm) were tracked (pingers and depth sensor transmitters) from a small boat over periods ranging from 98 to 108 days in Robertville Lake (elevation: 490 m; area: 63 ha; max. depth: 47 m). Whitefish were consistently mobile but showed quite variable lake use patterns. Two individuals traveled the entire length and breadth of the lake, whereas others remained in movement in the deep zone in the middle part of the lake or near the retaining dam wall. Whitefish occupied positions in the water column ranging from 2.6 to 27.0 m (mean 12.7 m ± 5.6 m) that varied depending on individuals. This first study on individual whitefish behaviour provides a better understanding of the behavioural ecology of the species in small artificial lake. [less ▲]

This paper deals with the solution of an optimal power flow (OPF) problem by the interior point method (IPM). The latter is a very appealing approach to this nonlinear programming problem due to its speed of convergence and ease of handling inequality constraints. Two interior point algorithms are presented and compared: the pure primal-dual and the predictor-corrector. Several implementation aspects of these IPM algorithms are also discussed. The OPF is formulated in rectangular coordinates which confers some significant advantages because generally its objective and constraints are quadratic functions. Among the large variety of OPF objectives, emphasis is put on two classical ones: the minimization of generation cost and the minimization of transmission active power losses. The solution obtained by both algorithms proves to be robust for the two OPF sub-problems (optimization of active power flows and reactive power flows) as well as for a full OPF applied to the former objective, which is unanimously recognized as the hardest problem to solve. Finally, numerical results on three test systems ranging from 60 to 300 buses are provided. [less ▲]

The Huygens probe is the ESA’s main contribution to the Cassini/Huygens mission, carried out jointly by NASA, ESA and ASI. It was designed to descend into the atmosphere of Titan on January 14, 2005, providing surface images and scientific data to study the ground and the atmosphere of Saturn’s largest moon. In the framework of the reconstruction of the probe’s motions during the descent based on the engineering data, additional information was needed to investigate the attitude and an anomaly in the spin direction. Two years before the launch of the Cassini/Huygens spacecraft, in May 1995, a test probe called SM2 (Special Model 2) was dropped in the Earth’s atmosphere from the balloon launch site of Kiruna, Sweden, to verify proper operation during the descent and especially the parachute deployment sequence. It featured a flight standard structure and DCSS (Descent Control SubSystem) and, unlike the Huygens probe, was fully instrumented to monitor the orientation of the descent module (3-axes accelerometers and gyroscopes). We describe how a comparison between the SM2 test flight and the Huygens mission provides some useful information about the Huygens probe’s behavior. After discussing the spin direction, we focus on the tip and tilt. The final conclusions of this comparison at the time of writing are still of qualitative nature, but the results are a starting point for better interpretation of the engineering data in terms of attitude to derive the probe’s orientation.

La cryptorchidie affecre environ 1 garçon sur 150 et dans près de 20% des cas, la gonade n'est pas palpée. Lorsqu'il est présent, le testicule non palpable est situé entre l'orifice externe du canal inguinal et le pôle inférieur du rein. Souvent cependant, lors de l'exploration chirurgicale, on constate l'existence de reliquats tissulaires à l'extrémité de vaisseaux spermatiques borgnes sans que l'on puisse reconnaître à proprement parler un testicule: on parle alors de testicule absent. Dans d'autres cas, on ne trouve pas de trace de vaisseau spermatique, de structure épidydimo-déférentielle ou encore de tissu testiculaire; il s'agit d'agénésie gonadique. Le testicule non palpé présente un risque accru d'infertilité, de transformation maliine, de hernies et malformations épididymo-déférentielles associées. Le traitement chirurgical est souvent plus complexe et les échecs plus fréquents. De nombreuses techniques d'imagerie ont été proposées comme modalités diagnostiques pour localiser le/les testicule(s) non palpé(s) (pneumopéritonéographie, angiographie, ultrasonographie, tomodensitométrie computérisée, RMN) mais aucune d'elles, à ce jour, n'est uniformément acceptée en raison du manque de fiabilité à détecter le testicule recherché et/ou des dangers potentiels résultant de leur emploi. Depuis la description par Cortesi en 1976 de l'utilisation de la cælioscopie pour la localisation du testicule impalpable, un intérêt croissant a été porté par les urologues et les chirurgiens pédiatriques à cette technique qui aujourd'hui joue un rôle central dans l'exploration du testicule cryptorchide non palpé. Les auteurs tentent d'établir une méthodologie algorythmique d'investigation des testicules cryptorchides non palpés à la lumière des données anatomiques, pathologiques et chirurgicales récentes de la littérature.
