[more ▼] Ce travail porte sur les pratiques touristiques dans les villes d’art, témoignées et textualisées dans la photographie d’amateur. Il étudie notamment les configurations textuelles que j’ai distinguées ainsi : 1) photo de monument, 2) photo de paysage urbain, 3) photo-panorama, 4) photo « en raccourci », 5) photo-journal intime. Ce catalogage vise à montrer les différentes manières d’inscription du corps et de l’identité (soi-idem et soi-ipse) du producteur et de l’observateur sur l’architecture et les espaces de la ville d’un côté, et sur le support photographique de l’autre. Ces configurations de points de vue ont été étudiées non seulement en relation entre elles, mais aussi en relation avec d’autres configurations textuelles, comme par exemple celles de la photo-souvenir de « paysage naturel », et en relation avec d’autres statuts sociaux de la photo, comme ceux du portrait de famille, du reportage de voyage dans la presse et du reportage « d’auteur ».

[more ▼] La réalisation de scénarios pédagogiques à l’aide d’un canevas de conception est un révélateur de compétences technologiques, organisationnelles et pédagogiques tant chez des enseignants en formation initiale que continuée. L’utilisation d’un tel canevas amène les enseignants à formaliser les activités d’apprentissage, sous-tend une approche réflexive et garantit une concordance entre les objectifs visés, les activités envisagées, la qualité des ressources technologiques et l’évaluation ainsi que la prise en compte du contexte organisationnel.

[more ▼] In the context of multistage stochastic optimization problems, we propose a hybrid strategy for generalizing to nonlinear decision rules, using machine learning, a finite data set of constrained vector-valued recourse decisions optimized using scenario-tree techniques from multistage stochastic programming. The decision rules are based on a statistical model inferred from a given scenario-tree solution and are selected by out-of-sample simulation given the true problem. Because the learned rules depend on the given scenario tree, we repeat the procedure for a large number of randomly generated scenario trees and then select the best solution (policy) found for the true problem. The scheme leads to an ex post selection of the scenario tree itself. Numerical tests evaluate the dependence of the approach on the machine learning aspects and show cases where one can obtain near-optimal solutions, starting with a “weak” scenario-tree generator that randomizes the branching structure of the trees.

[more ▼] Inbreeding depression results from mating among genetically related individuals and impairs reproductive success. The decrease in male mating success is usually attributed to an impact on multiple fitness-related traits that reduce the general condition of inbred males. Here, we find that the production of the male sex pheromone is reduced significantly by inbreeding in the butterfly Bicyclus anynana. Other traits indicative of the general condition, including flight performance, are also negatively affected in male butterflies by inbreeding. Yet, we unambiguously show that only the production of male pheromones affects mating success. Thus, this pheromone signal informs females about the inbreeding status of their mating partners. We also identify the specific chemical component, hexadecanal, probably responsible for the decrease in male mating success. Our results advocate giving increased attention to olfactory communication as a major causal factor of mate-choice decisions and sexual selection.

[more ▼] 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.

[more ▼] We propose a new delay-based scheduler called as RD-VC (Relative Delay VirtualClock). Since it performs a delay-based service differentiation among flow aggregates, the quality at microflow level is the same as that at aggregate level. This is not easily achievable when the service differentiation is bandwidth-based or loss-based. Unlike the EDF (Earliest Deadline First) scheduler [1], our proposed scheduler self-regulates and adapts the delays according to load changes. This characteristic permits its to implement it in an AF-like PHB providing the relative quantification service in a DiffServ network. Finally, we compare our proposed RD-VC scheduler with two important existing propositions: WTP (Waiting Time Priority) [2, 3] and EX-VC (Extended VirtualClock) [4]. Both these propositions are delay-based and have self-regulation property All three schedulers (RD-VC, WTP and EX-VC) maintain the required service differentiation among aggregates and have comparable long term average performance like mean throughput per aggregate and packet loss ratio etc. However, RD-VC and WTP take an edge over EX-VC at short-term performance like jitter. Both RD-VC and WTP have good long term and short-term performance. Our proposed RD-VC, compared to existing WTP, has two additional characteristics, i.e. unlike WTP which is limited to architectures with one queue per QoS class, it has no limitation on implementation scope (with or without separate queues per class) and it has lower complexity. This renders RD-VC an interesting proposition.

[more ▼] Scheduling Data-Intensive Bags of Tasks in P2P Grids leads to transfers of large input data files, which cause delays in completion times. We propose to combine several existing technologies and patterns to perform efficient data-aware scheduling: (1) use of the BitTorrent P2P file sharing protocol to transfer data, (2) data caching on computational Resources, (3) use of a data-aware Resource selection scheduling algorithm similar to Storage Affinity, (4) a new Task selection scheduling algorithm (Temporal Tasks Grouping), based on the temporally grouped scheduling of Tasks sharing input data files. Data replication is also discussed. The proposed approach does not need an overlay network or Predictive Communications Ordering, making our operational implementation of a P2P Grid middleware easily deployable in unstructured P2P networks. Experiments show that performance gains are achieved by combining BitTorrent, caching, Storage Affinity and Temporal Tasks Grouping. This work can be summarized as combining P2P Grid computing and P2P data transfer technologies.

[more ▼] European estuaries are subject to intense anthropogenic disturbance reflected in elevated loading of detrital organic matter, which induce high respiration rates and the production of large quantities of dissolved CO2. The Scheldt basin covers one of the most populated and industrialised areas of Europe and its tributaries drain an area of about 21,860 km2. The amounts of nutrients discharged by the Scheldt increased considerably during the past 20 years. Due to the dilution and metabolic processes of the downstream river flow in the estuary, an important variability of several parameters can be observed amongst which phytoplankton species and concentration, particulate organic matter, colour dissolved organic matter and suspended matter. In the present days, researches on the functioning of estuarine and coastal ecosystems are based on highly time consuming, costly sea campaigns and laboratory analyses. Although optical spaceborne remote sensing already proved useful in such coastal ecosystem studies, hyperspectroscopy opened a new dimension by allowing improved distinction of various biogeochemical compounds through characteristic spectral signature identification. Water quality variables were examined in the Scheldt estuary and plume, using CASI-2 (Compact airborne Spectrographic Imager) hyperspectral sensor and in situ bio-optical observations. The numerous parameters and spectrum measured in each station were used for further remote sensing analysis, as well as to complete the interpretation of the observed environmental processes. Multiple regression approach has been used to derive correlation between classical ground truth measurements and the rich information provided by the numerous CASI spectral bands. From these relations, some synoptic maps of biogeochemical parameters could be derived in the Scheldt estuary and plume. [less ▲] Detailed reference viewed: 14 (4 ULg) Scheler critique de Husserl.

[more ▼] Nous nous proposons de retracer les divergences qui caractérisent les philosophies de Husserl et Scheler en partant du principe que c’est bel et bien dans le contexte de la naissance de la phénoménologie qu’elles doivent être toutes deux envisagées. Nous commencerons par retracer le tournant transcendantal de Husserl avant de voir combien ce même tournant poussera Scheler à prendre ses distances avec lui pour évoluer un temps aux côtés de Heidegger. Ensuite, nous tâcherons de montrer combien leurs ontologies respectives les mènent l’un et l’autre à des conceptions de la réduction eidétique radicalement différentes. Enfin, en guise de conclusion, c’est l’issue même de cette réduction et, plus généralement, de la phénoménologie de Scheler que nous tenterons de dégager. Accordons d’emblée qu’il est effectivement difficile de faire l’impasse sur la dimension personnaliste de l’œuvre de Scheler. Néanmoins, nous allons ici nous atteler à une stricte mise à l’épreuve de sa pensée en tâchant de l’évacuer. Cette restriction dans l’analyse nous permettra de mettre en relief une tentative de « pensée » phénoménologique à notre sens judicieuse. Peut-elle alors conserver sa cohérence si on lui concède une échappée « hors phénoménologie » ?
