Modeling and control of a solar power plant using support vector learning is considered in this work. The model is based on a radial basis function network architecture and uses subtractive clustering and support vector learning to find the parameters and size of the network. To achieve a more interpretable structure the proposed method proceeds in two phases. Firstly, the input-output data is ...

Similar to animal stem cells, plant stem cells require special niche microenvironments to continuously generate the tissues that constitute the plant body. Recent work using computer modeling and live imaging is helping to elucidate some of the mechanisms responsible for the specification and maintenance of stem cells in the root and shoot.

The paper describes work in progress the application of process-oriented modeling to situation assessment within a research project in limnology. In the field study, some 50 lakes in Southern Germany are monitored in order to explore and document the changes in the distribution of a particular aquatic plant, Najas marina, and understand their preconditions. The ultimate objective is using this ...

In this paper, we propose an image-driven 3D modeling technique for rapid panel design. Our semi-automatic approach is based on template technique and mesh volume deformation controlled by a special cage. We designed our modeling system to be interactive in 2D, automating the process of shape generation while relying on the user to provide image samples. Once a parametric model template is give...

L-studio and the Virtual Laboratory (Vlab) are two related plant modeling packages developed at the University of Calgary, Canada. They have been distributed by this University since 1999. The packages run on Windows and Linux machines, respectively, have similar functionality, and support the exchange of models between both systems. The main difference between these systems is the user interfa...

this paper presents the steady state behavior and maintenance planning of the bleaching system in a paper plant. the paper plant comprises of various systems including feeding, chipping, digesting, washing, bleaching, screening, stock preparation and paper making, etc. one of the most important functionaries of a paper plant, on which quality of paper depends, is the bleaching system, where rem...

Background Lignin is a natural polymer that is interwoven with cellulose and hemicellulose within plant cell walls. Due to this molecular arrangement, lignin is a major contributor to the recalcitrance of plant materials with respect to the extraction of sugars and their fermentation into ethanol, butanol, and other potential bioenergy crops. The lignin biosynthetic pathway is similar, but not ...

This paper deals with the mathematical modeling and performance optimization for the Digesting system of a Paper Plant using Genetic Algorithm. The Digesting system of a Paper Plant has four main subsystems, arranged in series and parallel. Considering exponential distribution for the probable failures and repairs, the mathematical formulation of the problem is done using probabilistic approach...

The management of the processes related to proposal, design, construction, start-up, operation and decommissioning of industrial plants, in few words the whole Plant Lifecycle, are usually performed each by means of a specialised information tool, because of the peculiarities of the Engineering and Contracting (E&C) sector. The E&C Companies are aware of the need to move towards an integration ...
