Economic priorities of the strategic planning of forest sector in the Russian Federation
Branch and regional prioritization of the forest sector is a necessary condition for its development and compatibility growth. It allows toplan and forecast the forest management activities and their allocation across the country. Strategic planning and forecasting should use the following methodology. Firstly, it is necessary to rank the priority ...
Towards the Automatic Tuning of Linear Controllers Using Iterative Learning Control Under Repeating Disturbances
In this paper, iterative learning control (ILC) is proposed as an alternative approach that can be used to simplify the design of linear controllers for rejecting repetitive disturbances affecting a system. Since ILC is a data-driven method, its usage allows rejecting repetitive disturbances without a priori knowledge of their nature. The benefits ...
An iterative region growing algorithm to generate fuzzy management zones within fields
Management zones are within-field spatial units that are more homogeneous than the rest of the field and that have different factors or values than other areas of the field. While most algorithms tend to delineate fixed management zone borders, it is acknowledged that within-field variations between management zones are more gradual than sharp, mai...
ProTraS: A probabilistic traversing sampling algorithm
In the process of knowledge discovery in big data, sampling is a technological brick that can be included in a more general framework to speed up existing algorithms and contribute to the scalability issue. Two challenging and connected problems arise with complexity: tuning and timing. ProTraS1 is a new algorithm that fulfills both requirements. I...
Many-parameter M-complementary golay sequences and transforms
In this paper, we develop the family of Golay–Rudin–Shapiro (GRS) m-complementary many-parameter sequences and many-parameter Golay transforms. The approach is based on a new generalized iteration generating construction, associated with n unitary many-parameter transforms and n arbitrary groups of given fixed order. We are going to use multi-param...
Extended orthogonal matching pursuit for robust and fast target localisation in multiple-input multiple-output radar
The multiple-input multiple-output (MIMO) radar combines ultra-wide angular illumination on transmit and narrow transmission angular resolution after processing on receive. Orthogonal waveforms are needed in theory for all independent transmitters, but this property is usually not achievable in practice, therefore leading to a degraded ambiguity fu...
A fast and flexible instance selection algorithm adapted to non-trivial database sizes
In this paper, a new instance selection algorithm is proposed in the context of classification to manage non-trivial database sizes. The algorithm is hybrid and runs with only a few parameters that directly control the balance between the three objectives of classification, i.e. errors, storage requirements and runtime. It comprises different mecha...
Optimisation et parallélisation du code Fafemo d'écoulements en milieux poreux non saturés
Ce rapport présente le travail effectué au sein de l’UMR EMMAH à Avignon sur le code éléments finis Fafemo. Ce code donne une solution numérique des équations non linéaires de Richards traduisant les écoulements dans les milieux poreux non saturés. J’ai d’abord amélioré le code séquentiel en utilisant des méthodes itératives pour résoudre les systè...
An explicit formulation of the multiplicative Schwarz preconditionner
We provide an explicit formulation of the splitting associated with the Multiplicative Schwarz iteration. We show the advantage of considering the explicit formulation, when the iteration is used as a preconditioner of a Krylov method.
