This paper introduces a new open-source cross-platform software library written in C++ programming language which is able to serialize and deserialize hierarchically arranged class instances and their data members via XML files. The library provides easy and efficient way for processing, storing and managing complex object-oriented data with relationships between object instances. The library is based on mature cross-platform toolkit called wxWidgets and thus can be successfully used on many target platforms such as MS Windows, Linux or OS X. The library is published under open source licence and can be freely utilised in both open source and commercial projects. In this article, we describe the inner structure of the library, its key algorithms and principles and also demonstrate its usage on a set of simple examples.

The objective of this study is to develop an algorithm for detecting oestrus in dairy cows from measurements of activity and duration of lying/standing periods. The algorithm derived in this paper analyses measurements of activity and measurements of lying/standing periods. Each cows activity is measured by a necklace attached sensor that returns an activity index for each hour. Lying period duration is measured by a sensor attached on the cows hind leg. Activity and lying/standing behaviour are modelled as a discrete event system, constructed using automata theory. In an attempt to capture a biologically inspired lying balance, a lying balance indicator is constructed and is influencing transition probabilities in the stochastic automaton. The cows lying-balance indicates how much the cow has been resting during the immediately past period, and the balance express to the automaton, the tendency of the cow to continue resting or not. Change detectors are designed based on probability maximization ideas and results of decision algorithms are presented for oestrus detection. Detection based on the lying balance indicator and the two sets of measured information are demonstrated to increase the detection sensitivity to 100% for the set of ten cows.

Robust control of Yeast Fed-Batch Cultures for Productivity Enhancement

Abstract This work proposes a robust control strategy for the optimizing control of fed-batch cultures of S. cerevisae. The process dynamics is characterized by a nonlinear kinetic model based on the bottleneck assumption and ethanol inhibition for a possible excess of substrate feeding. The control strategy is based on the feedback linearization technique, where the resulting free linear dynamics is designed so as to ensure a certain robustness to plant parameter variations. A feedforward loop achieves the correct critical substrate value, which is a function of the ethanol and oxygen in the culture medium. In addition, a robust Luenberger-like observer is designed taking plant parameter variations into account. Numerical experiments demonstrate the potential of the proposed approach as a tool for control design of fed-batch cultures.

Based on introduction of the background and the limitations of present methods for coal and gas outburst,A hybrid method for prediction of coal and gas outburst based on soft sensor and data fusion combining many associated dynamic and static influence factors is proposed. In the method, the data fusion method based on arithmetic mean and batch estimation is used to process the dynamic influence factors data obtained by multiple sensors. And the soft sensor model based on fuzzy BP ANN predicts the dangerous status of coal and gas outburst according to the static factors data and the processed dynamic factors data. The application results show that the proposed method has high accuracy,and it is a practical method to dynamically and accurately predict coal and gas outburst.

This paper presents ontlology-based architecture for pattern recognition in the context of static source code analysis. The proposed system has three subsystems: parser, OWL ontologies and analyser. The parser subsystem translates the input coded to AST that is constructed as an XML tree. The OWL ontologies define code patterns and general programming concepts. The analyser subsystem constructs instances of the input code as ontology individuals and asks the reasoner to classify them. The experience gained in the implementation of the proposed system and some practical issues are discussed. The recognition system successfully integrates the knowledge representation field and static code analysis. resulting in greater flexibility of the recognition system.

The categorization problem in object recognition is the assignment of semantic categories to objects or parts of objects. Here, the best categorization performance provide mammalian brain functions that motivate to partly mimic such a formation for the application to machine learning and automation. Curiosity and experimental willingness support human recognizing and detecting in relation to still unknown objects. In order to learn an understanding of the topology of such objects, objects are observed from a series of different viewpoints. This results in a collection of object views that afterward can be used by cognitive processes. State-of-the-art systems provide learning structures that are subsequently utilized for object recognition and tracking tasks. However, most of these systems aim at very specific goals in restricted domains, and therefore, it remains no room for learning and understanding of object structures. In the work of this paper, we propose a new robot vision model for neural categorization. This is close to our initial idea of mimicking mammalian brain functions for robot vision. We use the combinatorial solution of our cognitive framework with an embedding of a recently presented stochastic n-gram model, supported by a three-dimensional grammar model on a discrete three-dimensional lattice. Furthermore, we use ant colony optimization heuristics for collecting the transition probabilities of the n-gram model. The proposed solution is exemplified by applying the method to several object view series of 69 polytopes generated out of the five platonic solids by truncation;thus, generating images from 32 viewpoints each, yields an object set of 2208 images. These set is further expanded to four sets perturbed by Gaussian-noise with varying σ = {0, 0.1, 0.5, 1, 2}. Finally, we show results for selected objects and conclude with an outlook on further work. © 2008 IEEE.

Optimal pulse width modulation (PWM) problem is an established method of generating PWM waveforms with low baseband distortion. In this paper we focused on computation of optimal switching angles of a odd PWM waveform for generating general odd symmetric waveforms. We introduce an exact and fast algorithm with the complexity of only O(n log2 n) arithmetic operations. This algorithm is based on transformation of appropriate trigonometric equations for each harmonics to a polynomial system of equations that is transferred to a special system of sum of powers. The solution of this system is carried out by modification of Newton's identity via Padéapproximation and orthogonal polynomials theory and property of symmetric polynomials. Finally, the optimal switching sequence is obtained by computing the zeros of two orthogonal polynomials in one variable. © 2008 IEEE.

This paper explores the possibilities of using the combination of the state of the art nonlinear programming problem solver IPOPT and the initial value problem solver CVODES (incorporated in SUNDIALS) for the solution of dynamic optimization problems, also regarded as open loop optimal control problems (OCP). Recent works confirm the potential of IPOPT in solving large scale optimization problems and particularly in solving optimal control problems in the framework of the complete parameterization approach [12]. Here the OCP problems are solved using the control vector parameterization scheme and the advantages and disadvantages of the combination CVP + IPOPT + CVODES are evaluated through several examples.
