A new generation of space-borne SAR sensors were launched in 2006-2007 with ALOS, TerraSAR-X, COSMO-Sky-Med and RadarSat-2 satellites. The data available different bands (L, C X bands), High Resolution (HR) or multi-polarization modes offer possibilities to monitor glacier displacement surface evolution by remote sensing. In this paper, the first results obtained TerraSAR-X HR image time series acquired over temperate glaciers Chamonix Mont-Blanc test site are presented. This area involves...
Abstract In the days to weeks following an earthquake, landslides can display specific post-seismic motions, including delayed initiations and relaxations. These motions have uncertain origin, sometimes attributed specificities of landslide basal interface or fluid transports in shear zone. Here we address this question, by documenting co- slow-moving accelerated Gorkha earthquake (Mw 7.8, 25/04/2015, Nepal). We detect 11 over area 750 km $$^2$$ <mml:math...
We introduce a theoretical algorithm and its practical version to perform decentralized detection of the global convergence parallel asynchronous iterative algorithms. prove that, even if is completely decentralized, achieved on one processor under classical conditions. The proposed very useful in context grid computing which processors are distributed detecting master may be penalizing or impossible as peer computation frameworks. Finally, efficiency illustrated typical experiment.
Abstract The flow of Glacier d’Argentière, French Alps, has been extensively studied by glaciologists for >100 years, but high-temporal- and high-spatial-resolution monitoring its dynamics rarely carried out. In this paper, the terminal part main glacier was selected to undertake such a survey. 2 month experiment (September–November 2013) included remote sensing map velocity field whole area, network in situ measurements record ice at surface as well base with high precision temporal...
In this paper, 3 years of surface displacement measurements obtained by space-borne synthetic aperture radar (SAR) observations are presented over the Argentière glacier in Mont-Blanc massif, France. This temperate is instrumented a network four Global Positioning System (GPS) stations used as ground truth. Thirty-eight pairs descending and ascending high-resolution TerraSAR-X (TSX) acquisitions covering study region to derive fields at 11-day intervals spring summer 2009 2011. The...
Most of the image processing techniques have been first proposed and developed on small size images progressively applied to larger data sets resulting from new sensors application requirements. In geosciences, digital cameras remote sensing can be used monitor glaciers measure their surface velocity by different techniques. However, number acquisitions processed analyze time series become a critical issue derive displacement fields conventional correlation technique. this paper,...
In this paper, we present a method for combining image-based displacements to build time series. This takes advantage of the redundancy these which comes from multiple possible combinations between images. The proposed combines common master series having different date, in order construct single relative displacements. We were able test on computed using images stereo lapse device recording Argentire glacier during summer and fall 2019. Our was compared two other displacement aggregation...
In this paper, first order diffusion load balancing algorithms for totally dynamic networks are investigated. Totally in which the topology may change dynamically. Some edges or nodes can appear, disappear move during time. our previous works on networks, dynamism was limited to edges. The main result of study consists proving that reduce unbalance arbitrary networks. Notice hypotheses realistic and example network does not have be maintained connected. To behavior these algorithms, we...
Domotic systems aim to offer functionalities like energy management, security, conveniences, and much more. Many domotic networks exist provide a subset of these applications, but are not necessarily compatible due different communication mediums or protocols. Literature presents studies that introduce high-level solve the lack incompatibility, it does explore how create network behavior. This paper concentrates on studying model unit behaviors home devices global behavior devices: automated...
Nowadays, data fusion constitutes the key subject in numerous applications of remotely sensed displacement measurements, with increasing availability remote sensing and requirement improving measurement accuracy. This article addresses current status challenges measurements. An overview is given to discuss sources techniques extensively used for recent development achievement measurements fusion. The between integration a geophysical model are discussed. strategies uncertainty propagation...
Adaptive systems represent an appropriate solution to the increasing complexity of software-intensive systems.We developed WOF, a Wise Object Framework develop self-adaptive software we name "Wise systems".Those consist distributed communicating objects (Wise Objects: WOs) able autonomously learn on how they behave and are used while demanding little attention from their users.A WO is either delivering service (Awake state) or simulating its operation behavior that has not occurred yet...
This paper presents the first results obtained with satellite image time series (SITS) acquired by Cosmo-SkyMed (CSK) over Chamonix Mont-Blanc test-site. A CSK SITS made of 39 images is merged a TerraSAR-X 26 using orbital information and co-registration tools developed in EFIDIR project. The are illustrated computation speckle-free temporal averaging, generation comparison topographic interferograms measure glacier displacement fields amplitude correlation.
In this paper a new method of distributed load balancing is given. This could be described as generalization the dimension exchange on hypercube topologies with dynamic links. A network links assumes that edges topology may broken down, but no processor dynamically added network. We suppose in physical or logical sense, i.e. communication channels are organized hypercube. The main result consists proving convergence toward uniform distribution algorithm hypercubes edges. need few conditions...
This paper investigate a mutual exclusion algorithm on distributed systems. We introduce new based the Naimi-Trehel algorithm, taking advantage of approach while allowing to request partial locks. Such ranged locks offer semantic close POSIX file locking, where threads lock some parts shared file. evaluate our by comparing its performance with original and centralized algorithm. The considered metric is average time obtain lock.
In this position paper we identify the design of "wise systems" as an open research problem addressing new technology-based systems.Increasing complexity and sophistication make those systems hard to understand master.Human users are very often involved in learning processes that capture all their attention while being little interest for them.To alleviate human interaction with such systems, foundation ongoing research, propose concept object" building block.Software-based would then be...
