The collision activated dissociation and dissociative photoionization of 1,1- and 1,2-C2H2F2 in the HF-loss channel are investigated. The measured KER ditributions are interpreted by the opening of two competitive reaction channels leading to two C2HF+ isomers. This hypothesis is checked by ab initio calculations. [less ▲]

The Belgian Crop Growth Monitoring System (B-CGMS) uses the 1km²-resolution imagery of NOAA-AVHRR and SPOT-VEGETATION to improve its yield estimates. The pre-processed images are converted to fAPAR and combined with meteorological data (irradiance, temperature) to daily growth values by means of the Monteith approach. The regional means of the cumulative monthly growth numbers are calibrated against official harvest statistics by means of crop-specific neural networks. The quality of the yield estimates varies with the importance of the crop: the R²-values for winter wheat, sugar-beets and fodder maize are respectively 60%, 48% and 36%. The final yield forecasts will be better, because the B-CGMS integrates the image-based yield estimates with the assessments of the agromet-model and of the technological trend function. The technique of linear unmixing seems promising but in its actual state it is too unpredictable to be included in an operational scheme. [less ▲]

evapotranspiration experts often need to make decisions relating to the precision of the results of various existing methods such as traditional and satellite methods. For these reasons a decision support system (EVA) is develped in order to provide evapotranspiration experts with a tool for evaluating the results of a variety of existing methods for estimating potential and real evapotranspiration by using in situ data and remote sensing data. The EVA provides a variety of models that can be used either in combination or as stand-alone tools to generate information for agricultural planning and management. The paper focuses on the concepts of the EVA software. A case study also will be presented. [less ▲]

Two ferrous matrix, a high speed steel and a maraging steel were reinforced with alumina, titanium and vanadium carbides. The composite was realized by powder metallurgy. The particles were mechanically mixed with the prealloyed powder before compaction. To optimize the composite properties, the processing parameters (i.e. prealloyed powders, size, mixing, conditions, temperature of sintering,...) and the effect of reinforcement (size and composition of particles, volume, fraction,...) were studied. It is necessary to obtain full density with minimum porosity and to control the size, distribution and dispersion of the reinforced particles. The optimal sintering temperature depends on the reinforcement particles used and is of great importance for the properties. Processing parameters (mixing of particles) can greatly affect the final properties. The use of AL2O3 was shown to increases wear resistance in the two matrix. [less ▲]

Based on the experimental results, earlier work presented a first attempt at the statistical modelling of the friction and wear valves and seals of rocket engines must withstand. Available friction coefficients and wear rates (as defined in Archard’s equation) were fitted against two independent variables : sliding speed and contact pressure. The computations yielded second-degree polynomials and the corresponding response surfaces. However, it was felt that a statistical design of experiments to reduce the test activities and maximise result quality was needed. A detailed analysis led to the choice of Doehlert’s approach, with a contribution of the general equiradial design. Testing was performed with a pin-on-disk tribometer capable of working at room temperature (RT) and under liquid nitrogen (at 77 K). The results pertaining to two examples are discussed. Statistical as well as practical aspects of the work performed and consequences of the results are covered : based on correlation factors and other mathematical indicators, on the general profile of the response surfaces and on requirements for use, the tribological properties of the considered materials are illustrated, leading to their eventual usefulness in cryotechnic equipment and space applications.

A la fin des années 1960, afin de répondre aux besoins des autorités locales, l’Institut national de statistique (I.N.S.) a pris l’initiative de découper le territoire communal de toute la Belgique en une vingtaine de milliers de secteurs statistiques. En vue du recensement de 2001, l’I.N.S. a décidé d’actualiser les limites des secteurs. À cette fin, un projet pilote de deux ans a été conçu. Il a pour objectif la mise au point d’une filière de production permettant: 1) de repérer, sur des images satellitaires, les zones rurales présentant des noyaux d’habitat (utilisation des 59 images HRV de SPOT des couvertures 1995 et 1996 de la Belgique); 2) de réaliser l’actualisation des secteurs statistiques par photo-interprétation assistée par ordinateur (PIAO) à partir des orthophotoplans. La méthodologie retenue comprend notamment: 1) le découpage du projet en «zones» homogènes de travail; 2) la réalisation du masque du bâti par classification non dirigée; 3) la détection des noyaux de bâti; 4) l’élaboration de la liste des secteurs dont le découpage doit être vérifié; 5) la création des nouveaux secteurs statistiques d’habitat groupé par PIAO. 7 467 noyaux ont été détectés dans 3 673 secteurs candidats à l’actualisation. Ces secteurs sont généralement localisés à la périphérie des villes et correspondent souvent à de nouveaux lotissements ou à un accroissement au départ d’anciens noyaux d’habitat. À terme, le nouveau découpage permettra à l'I.N.S. de ventiler ses statistiques sur des unités territoriales épousant mieux les limites des agglomérations. [less ▲]

Variable step strategies are specially well suited to deal with problems characterized by high non-linearity and contact/impact. Both phenomena are typical of dynamic simulations of the interactions between a turbine blade and its casing, the most dramatic example being blade loss. Constant step size strategies do not give satisfactory answer for this kind of problems, since it is very difficult, if not impossible, for the user to find an appropriate time step that does not lead to divergence nor generate extremely costly computations. An automatic time stepping algorithm is proposed, which takes into account the recent history of accelerations in the bodies under consideration. More precisely, the adaptation algorithm is based on estimators of the integration error of the differential dynamic balance equations. This allows for adaptation of the time step to capture correctly the transient phenomena, with characteristic times which can range from relatively long (in regime) to very short (blade loss), thus ensuring precision while keeping the computation cost to a minimum. Additionally, the proposed algorithm automatically takes decisions regarding the necessity of updating the tangent matrix or stopping the iterations, further reducing the computational cost. As an illustration of the capabilities of this algorithm, several numerical simulations of both academic and industrial (the contact/impact between a turbine blade and the casing) problems will be presented.

An automatic time step size determination for non-linear problems, solved by implicit schemes, is presented. The time step calculation is based on the estimation of the integration error. This estimation is calculated from the acceleration difference. It is normalised according to the size of the problem and the integration parameters. This time step control algorithm modifies the time step size only if the problem has a long time physical change. On the other hand, Hessian matrix can be kept constant for several iterations however the problem is non-linear. According to the fact that the time step size is constant for some time step, the Hessian matrix shouldn’t be recalculated for each time step. A criterion selecting if Hessian matrix must be calculated or not is developed. Finally, a criterion of iterations divergence is also proposed. It avoids the determination, by the user, of a maximal iterations number. The iterations number is the smaller. Industrial numerical examples are presented that demonstrated the performances (precision and computational cost) of the algorithms. [less ▲]

Several TCP-Friendly algorithms have been recently proposed to support multimedia applications. These algorithms try to mimic the congestion control behavior of TCP. However, the oscillatory (bursty) nature of TCP traffic is widely known to be unsuitable for most typical real-time applications. Adopting such behavior would result in annoying QoS oscillations for the users of such real-time applications. In the present paper we describe a new TCP-Friendly algorithm based on the TCP cycle estimation. We show through simulations that the proposed algorithm is able to smooth the oscillations while keeping fairness towards TCP. [less ▲]

In the Differentiated Services (DS) framework, service differentiation is performed among the aggregates (collection of one or more microflows) rather than among the microflows (data stream pertaining to a single connection). We analyse three quality metrics namely bandwidth, loss and delay (that might be used for defining a service differentiation at a DS node) on two criteria 1) service differentiation should be respected at all loads and 2) service provision at aggregate level should scale down to microflow level without being microflow aware. We find that bandwidth requires microflow aware management, loss lacks in simplicity (though it satisfies the criterion # 2), and delay is the right candidate. Ensuring better delays at an aggregate level also means ensuring better delays for all the included micro flows, and additionally it is easier to define a scheduler that can adapt itself to the relative loads of the aggregates so that relative delays between aggregate are preserved at all loads. Our objective is to provide relative quantification service in DiffServ by a delay-based scheduler while satisfying both criteria. Delay is also a meaningful QoS parameter for both interactive real-time applications and TCP applications, since the mean TCP throughput is roughly inversely proportional to the RTT. We, therefore, develop a scheduler for Assured Forwarding (AF) PHB where service differentiation among aggregates is based on delays. We provide simulation results that prove that relative delays among aggregates are perfectly respected at all loads. [less ▲]

Respiratory disease is the principal cause of loss of young cattle worldwide. The syndrome arises from a number of factors, including Chose involving the animal, e.g., age, general condition and immune statue; ifs environment, e.g., changes in food, temperature and humidity that lead to stress; and the presence of infections agents, e.g., bacteria, viruses and mycoplasmas. The syndrome, in a method preferred by the author, can be classified into four grades: Grade 1, subclinical disease;Grade 2, compensated clinical disease (at this stage, the inflammatriry reaction generated tends to lirait the impact of the disease on thi animal); Grade 3, noncompensated clinical disease (at this stage, the inflamniattxy reaction is excessive and must be controlled); and Grade 4, irrevertibk clinical disease (which threatens the animal's survival). The increase in frequency and economic impact of bovine respiratory disease complex can be correlated with the escalating industrialisation of cattle production. In intensive operations, commingling of animale from multiple sources, exposure to many organisme, stress and management practicgs are all factors that can lead to disease. - The predisposition of cattle, especially beef calves, to respiratory problems is related to their lack of functional pulmonary hardiness. Selection of breeds that demonstrate adequate pulmonary function and sufficient ventilatory reserve may help in the control of the bovine respiratory disease complex, but this approach is difficult to implement and slow to produce results. Prophylactic measures, including vaccination programmes and modifying management practices to reduce stress, also have a place in preventing the bovine respiratory disease complex. Unfortunately, these measures are not always easy to put into operation and cannot completely eradicate the problem. Therapeutic strategies to minimise the economic impact of the syndrome include use of appropriate antibacterial therapy, modulation of the pulmonary inflammatory reaction and correction of mechanical disorders.

In the frame of XMM testing, all the mirror modules have been illuminated by a vertical EUV collimated beam a the Centre Spatial de Liege. A mirror module consists in 58 co- focal and co-axial Wolter I mirrors. Up to now the images obtained at CSL have been used to assess the Mirror Module optical performances in a flight representative configuration, and also to verify the impact of the thermal environmental and vibration test on the optical performance. Due to the highly complex design of the Mirror Modules, simulating XMM images in details is very difficult. The Point Spread Function of some of the mirror modules presents slight asymmetry. In the facility design study, it has been demonstrated that the diffraction impact at 58.4 nm is negligible with respect to the half energy width mirror module specification. Presently all the mirror modules are better than 165 arcsec. This paper presents first the diffraction contribution on the image. In a second step a point spread function is built by using the metrological mirror shell data. EUV images are then analyzed to evaluate the impact of the mirror interface structure integration process on the PSF. An analytical model of the measured EUV pSF is developed. The modelization technique is applied to simulate in-orbit image. Finally the different modelizations are evaluated and compared. [less ▲]

Nuclear imaging techniques have a long history in pulmonary medicine and the clinical and experimental uses of lung scintigraphy have largely expanded these last years. Currently, the pulmonary applications of nuclear scintigraphy are essentially: (I), the study of regional lung function; (II), the imaging of pulmonary infection and/or inflammation; (III), the determination of inflammatory cells involvement in lung diseases; (IV), the assessment of the alveolar-capillary barrier integrity; (V), the imaging of lung cancers and (VI), the study of aerosol deposition within the lung. Many faculty of veterinary medicine have acquired nuclear imaging facilities. The primary application of scintigraphy is in the investigation of equine orthopaedic conditions and, with the exception of rodents, only a few publications report the use of lung scintigraphy in any animal species. Nevertheless, lung scintigraphy using animals would be of great interest to better understand the lung physiology in general as well as animals’ peculiarities in particular. Following a brief introduction to the technique, this paper will review the main applications of pulmonary scintigraphy and will survey some new nuclear imaging techniques that should be available in the next future.

The characterisation of the behaviour of nonlinear aeroelastic systems has become a very important re- search topic. Nevertheless, most of the work carried out to date concerns the development of unsteady CFD solutions in the transonic region. Important though this work is, there is also a need for research which aims at understanding the behaviour of non- linear systems, particularly the occurance of Limit Cycle Oscillations (LCOs). The purpose of this pa- per is to study the stability of a simple aeroservoelas- tic system with nonlinearities in the control system. The work considers both structural and control law nonlinearities and assesses the stability of the system response by use of bifurcation diagrams. It is shown that simple feedback systems designed to increase the stability of the linearised system also stabilise the nonlinear system, although their effects can be less pronounced. Additionally, a nonlinear control law designed to limit the control surface pitch response was found to increase the flutter speed considerably by forcing the system to undergo limit cycle oscilla- tions instead of fluttering. Finally, friction was found to affect the damping of the system but not its sta- bility, as long as the amplitude of the frictional force is low enough not to cause stoppages in the motion. [less ▲]

In order to better understand the chemistry and the transport mechanisms in the lower troposphere, a new original technique has been developed and tested. The experiment consists in recording high resolution infrared solar absorption spectra containing signatures of important atmospheric constituents, simultaneously from the International Scientific Station of the Jungfraujoch in Switzerland [ISSJ, 3580 m a.s.l., 46.5 degrees N, 8 degrees E, Bruker 120 HR Fourier transform spectrometer (FTS)] and from a nearby valley (Grindelwald, 1070 m a.s.l., Bruker 120 M FTS). Analysis of individual spectra allows to determine vertical column abundances: differences between measurements at ISSJ and at Grindelwald enable us to retrieve the constituents' concentrations between 1070 m and 3580 m, assuming a constant volume mixing ratio in this layer. A first measurement campaign has been organized during the months of May and June 1998. After an initial period of instrument intercomparison at ISSJ, the mobile instrument was moved down in the valley and installed for one month in Grindelwald. When operated side by side at the Jungfraujoch, measurements made by both instruments showed a very good agreement (maximum bias of 1.5%). Analysis of spectra recorded synchronously at the Jungfraujoch and at Grindelwald gave average boundary layer concentrations for a selected set of tropospheric molecules, i.e. methane, nitrous oxide, carbon monoxide and ethane. Comparison with other results and with carbon monoxide in-situ measurements made at ISSJ showed a good agreement. [less ▲]

optics these last years. One of the disadvantages of ion figuring is the high surface temperature of the workpiece. Temperature aspects have already been mentioned by some authors but are weakly detailed. Therefore thermal effects on BK7 and Zerodur, mainly surface figure distortions and surface temperature measurements, have been investigated here in more detail. Distortion of the optical figure due to high temperature and temperature gradients induced by ion figuring is described. High figure distortion has been observed on 10 cm diameter BK7 samples. Distortions can also be observed on Zerodur samples (although much weaker). Differences between BK7 and Zerodur distortions are discussed. In order to analyse the nonuniform heating of the workpiece during ion bombardment, the surface temperature has been monitored with an infrared camera. Furthermore, surface temperature measurements with respect to ion beam parameters have also been performed. All these measurements show the necessity to care about thermal aspects during ion beam figuring for some sensible materials like BK7, but even for low expansion material like Zerodur. [less ▲]

An ion beam figuring facility is operational at the Centre Spatial de Liège since 1997. Its present capabilities are described. An extensive characterisation programme is running in order to determine the optimised parameters for various materials and operating conditions. In this frame, tests have been performed on a spherical gold-coated aluminium mirror plated in between with nickel. The nickel plating was used to be super-polished to a BRDF of 1 10-4 at 1 deg at 10 µm wavelength. Micro-roughness and etching rate measurements were realised and influence of ion bombardment on the coating has been established after removal of the gold coating. The gold coating removing was performed by using the ion beam flux. Finally, the mirror has been figured from the original sphere to a parabola. Surface characteristics evolution is also described in terms of micro-roughness and surface error. An overview of the research and development programmes related to this facility is given. Results of this technique and potential impact on optics fabrication are then briefly exposed. [less ▲]

The Differentiated Services (DiffServ or DS) framework takes an edge over IntServ because it is scalable and lesser complex. On the other hand, the application level end-to-end quality o f service, in DiffServ, may get compromised because: 1) network resources are not allocated at microflow level (a data stream pertaining to a single connection) but at aggregate level (collection of one or more microflows), 2) the DiffServ working group does not specify algorithms for PHBs but their output behavio urs and 3) end-to-end quality is function of Service Level Agreements (SLAs) between the adjacent domains transited by the connection and a large diversity in SLAs is quite evident as each DS domain would have different service provision policies. We focus, in this paper, on the first two issues. Our goal is to ha ve DiffServ deployed with all its simplicity and still be able to provide application level end-to-end qu ality of service. For that, we study a PHB for AF classes. A PHB comprises a packet scheduler and a packe t accept/discard algorithm. For packet scheduler, we use the Extended-VirtualClock (Ex-VC) algorithm. Ex-VC perfo rms delay-based service differentiation among the aggregates while selecting a packet for service. The reasons for having delay-based definition for service differentiation are: it is adaptable to load per aggr egate and it does not need to be microflow aware. Other definitions like bandwidth and loss may also be u sed but the former requires microflow aware management and the latter lacks in simplicity. For packet accept/discard algorithm, we use RED when all packets have the same drop precedence level and DI-RO (Deterministic for In-RED for Out) when packets are policed at the ingress DS node and packets viol ating the Service Level Agreement (SLA) are marked OUT. In DI-RO, IN packets are always accepted (except buffer overflow) whereas OUT packets are accepted probabilistically. [less ▲]

The determination of the vibration characteristics of rotating engine blades is very important for fatigue failure considerations. One of the most promising techniques for measuring blade vibrations is blade tip-timing. Three vibration analysis methods were used on data obtained from a simple mathematical blade tip-timing simulator. The results from the methods were compared statistically. One of the methods, the Global Autoregressive Instrumental Variables approach produced satisfactory results at realistic noise levels. However, all of the techniques produced biased results under certain circumstances. [less ▲]
