The PACS Grating Assembly consists of a flat ruled grating of 320x80 mm²; its positioning mechanism; and launch-locking system. The Grating Assembly is part of the PACS Focal Plane Unit (FPU) and is operated at liquid helium temperature (4K). It is remote-controlled from the Detector & Mechanism Controller (DEC/MEC), which is located on the Herschel Service Module. The grating shall be capable of accurate positioning (4 arcsec) within a large angular throw (40 arcdeg) and restricted dissipation to the 4K heat sink (< 5 mW). The development of the Grating mechanism controller has urged the need for a cryogenic simulator of the Grating Assembly with regard to the large change in value of mechanical and electrical characteristics between room temperature and liquid helium temperature. The simulator consists of a functional prototype of the Grating Assembly and a dedicated helium cryostat with appropriate interfaces. The test cryostat is a homemade facility (CSL) designed to cool down the prototype (and subsequent models) to liquid helium temperature. The test set-up also provides relevant instrumentation such as cryogenic temperature read-out, electrical feedthroughs toward the payload and optical viewport. [less ▲]

This paper discusses and compares three types of undervoltage load shedding closed-loop controllers in terms of performances and design computational effort. We first describe the various controllers and identify the parameters to be optimized. Next, we present an optimization methodology applicable to all three types of controllers. This approach allows to find the controller parameters which optimize an overall performance objectiw. Results are presented on the Hydro-Qukbec system, in which load shedding is presently planned.

In this paper, we address the problem of transporting vital commodities and emergency personnel during the response stage of a disaster relief operation by integrating fuzzy linear optimization and the principles of scenario analysis. We treat this transportation system as a probabilistic multi-commodity multi-modal network flow problem and first develop a fuzzy model that allows the satisfaction of demand requirements through different supply nodes over a fuzzy network. Since the available information in case of disasters is generally vague and imprecise about the values of model parameters, fuzzy linear optimization is employed to deal with this uncertainty and to generate different scenarios depending upon the preferences of the decision maker. Then these scenarios are handled within the framework of the scenario analysis by defining a scenario as a joint realization of the uncertain parameters. Here, scenario analysis method can be considered as a search for a robust solution that guarantees the maximum satisfaction of demands with the minimum transportation cost. [less ▲]

Microlensing consists in two major effects: (1) variation in the apparent position of the background sources (astrometric component) and (2) flux variations of the background sources (photometric component). While the latter has been extensively used in the search for dark objects in the Galactic disk and halo (projects like MACHO (Alcock et al, 1997), EROS (Derue et al, 1999), OGLE (Paczynski et al, 1994)), the first effect has not yet been part of a systematic observational program, simply because the observations of very slight displacements in the positions of background sources requires an astrometric accuracy which current telecopes do not yet provide. We investigate here whether the astrometric accuracy of GAIA could enable such measurements and, as a consequence, enable new, direct and original measurements of the mass of nearby stars. [less ▲]

Within the Southern Ocean, amphipods have achieved a conspicuous adaptative radiation which gave rise to the development of numerous feeding strategies (Jazdzewski et al. 1996; Dauby et al. in press; De Broyer et al. in press). The discrepancy between the ecological significance of amphipods in the Antarctic and our poor knowledge of their ecofunctional role calls for a more detailed investigation of their importance in this ecosystem trophodynamics. This study focused on the eight amphipods species which were collected and from which isotopic and lipidic (when available) (Graeve et al. in press) compositions were compared to their respective gut contents previously described (Dauby et al. in press). The interest of both first techniques rely upon the direct relationship between the isotopic signatures and the lipid composition of organisms and those of their diet (De Niro and Epstein 1978, 1981; Peterson and Fry 1987; Graeve et al. 1994; Cripps et al 1999). Amphipod stable isotope ratios and fatty acids composition correspond rather accurately to the trophic classification based on gut contents and attest to their high spectrum of feeding types. Since the fundamental difference between the approaches to diet studies is the time scale each method addresses, this coincidence indicates that there would be no significant changes in feeding strategies over time. Three levels of the food web are covered by the eight species and, instead of belonging strictly to one trophic category, amphipods display a continuum of values from the suspension-feeder to scavengers.

We present the properties of all the galaxies detected by ISO at 7, 15 and 90 microns in ELAIS northern fields. The spectral energy distribution (SED) of those 20 galaxies with IRAS detections can generally be well fitted by a predominant cirrus component plus a modest starburst contribution. Follow-up spectroscopy has shown that all the objects are emission-line galaxies but without a very intense star formation event. Most of the galaxies analyzed by means of optical R band photometry result to host an important exponential disk component, in good agreement with the SED IR modelling. We note that galaxies with morphological signs of perturbations seem to show slightly higher f[SUB]15[/SUB]/f[SUB]6.7[/SUB] ratios, indicating that star formation could be more important in them. One of the objects is a broad-line, radio-quiet quasar at z=1.099; its spectral energy distribution indicates that it is a hyperluminous infrared galaxy (HLIG), the first HLIG detected in the ELAIS areas.

An optimized configuration has been found allowing a fast recording (50 milliseconds) and large number of readouts (>1000) for analysis of events over a long period without reducing the measurement resolution.

This paper deals with the approximation concepts approach applied to structural optimization. In 1987, Svanberg proposed the method of moving asymptotes for solving structural optimization problems. This approximation is monotonous and can efficiently treat problems characterized by such a behavior. Svanberg (1995) proposed a modification of the MMA approximation by making it non monotonous. This property is based on an heuristically updated parameter. The resulting approximation is called GCMMA. In Bruyneel et al. (1999), it is shown that it is possible to generate non monotonous GCMMA based approximations, called GBMMA, by using the gradient and/or the function values from previous iteration. It was shown that such approximations improve the convergence speed of the optimization process. In many optimization problems (for example composite structures optimization or simultaneous sizing and optimal configuration of truss structures), the structural responses present both monotonous and non monotonous behaviors. A mixed monotonous/non monotonous approximation scheme has to be used for approximating in the best way the optimization problem (Zhang et al., 1998 and Bruyneel and Fleury, 2000). In this paper, we propose to show that it is possible to derive a very general approximation of the MMA family based on gradients and/or functions values at two successive design step, that present a mixed monotonous/non monotonous behavior. This approximation scheme is based on the GMMA approximation of Dusyinx et al. (1995) and on the non monotonous GBMMA approximations of Bruyneel and Fleury (1999). As the approximation scheme proposed in this paper is general, it contains all the approximations of the MMA family described above, that is MMA, GCMMA, GBMMA and GMMA. According to the characteristics of the problem under consideration, one of those approximations or of a mix of them is used to solve the optimization problem. This selection can be automatic or based on the designer’s knowledge. Numerical applications will show that the derived GMMA/GBMMA approximation scheme is efficient for solving structural optimization problems. Results will be compared with the ones obtained with the other approximations of the MMA family. [less ▲]

Introduction: Recent studies have shown that some steroidal anti-inflammatory drugs (NSAIDs) could exert their actions by multifactorial processes. Among them, the potential antioxidant activity of certain NSAIDs towards various reactive oxygen species (ROS) is often suggested and could have pharmacological relevance. Objective: This study was designed to assess the potential antioxidant properties (IC50 values) of aceclofenac and its metabolites (4’OH-aceclofenanc and diclofenac) on three different systems of ROS production, using chemiluminescence (CL) technique with luminal and electron spin resonance (ESR) spin trapping. Material and Methods: Isolated human PMNs (1x106 cells) were activated with 5x10-7 M PMA in the presence of luminal (CL assays) with or without drug addition. For spin trapping experiments, 100 mM DMPO, a radical trapping agent, was added to the reaction milieu containing 6x106 cells/ml. For free-cell experiments, the Fenton’s reagent was used for generation of ·OH and xanthine/xanthine-oxidase system for O2-radicals. The NaOCl-induced CL, amplified by luminal, was used to test the drug effects on HOCl. Results: On the model of PMA-activated PMNs, 4’OH-aceclofenac exhibited the best antioxidant profile (IC50 = 10 µM) while the effect of the parent drug was less pronounced (IC50 = 100 µM). Diclofenac did not inhibit CL response even at the high dose of 1 mM. Quite similar results were obtained on the NaOCl-induced chemiluminescence, where the efficacy of the drug was as follows: 4’HO-ACE (25 µM) > ACE (1 mM) > DICLO (no effect at 1 mM). By ESR technique, 4’HO-ACE also showed an inhibitory effect (501 µM) on the ROS production by PMA-activated PMN as well as on the ·OH production, while ACE (IC50 = 100 µM) was less efficient and DICLO (IC50 = 1 mM) without significant effect. These findings indicate that beside its anti-inflammatory effects, aceclofenac acts as an antioxidant, at least in part, by the way of its metabolite especially 4’HO-ACE. [less ▲]

Motivated by issues in temporal databases and in the verification of infinite-state systems, this talk considers the problem of representing periodic dense time information. Doing so requires handling a theory that combines discrete and continuous variables, since discrete variables are essential for representing periodicity. An automata-based approach for dealing with such a combined theory is thus introduced. [less ▲]

Air composition in dwellings and public buildings is studied by means of gas chromatography and a sensor micro array 01D28 (MICROSENS, Swiss). Only benzene and its alkyl-derivatives are quantified. The micro array 01D28 is composed of six metal oxide gas sensors (SnO2 doped by Pd) equipped with standard or inter-digited electrodes. Isothermal working mode (500oC for all sensors) is applied. Conductivities after 10 minutes of signal acquisition in the studied air are considered as characterizing its chemical composition. Discriminant Function Analysis (DFA) and different linear regression techniques (Inverse Least Squares, Principal Components Regression and Partial Least Squares) are applied to find a relation between the sensors signals and the indoor air composition as determined by the gas chromatography. The presented results suggest that the monitoring of aromatics substances in the indoor air by means of a micro-array of metal oxide gas sensors is possible. The array distinguishes polluted and non-polluted air and it can even evaluate the concentration of the benzene and the toluene. [less ▲]
