Software implementation of the Data-Driven SIMCA method (DD-SIMCA Toolbox)
The article is dedicated to implementation and evaluation of a model for simulation of emergency situations on main gas pipeline. Data produced by model was compared to data obtained from real emergency situations on main gas pipeline. Result of this work is the model built using MATLAB Simulink software that can be used for datasets generation, which are useful for artificial neural networks training.
An approach to modeling is proposed, where the airplane is considered as a system with a minimal set of basic material points, and its mathematical description is given. We construct the mathematical model of the conventional airplane with an adequate accuracy for evaluation calculations in creating the control system. The flight simulation software for the Yak-52 and NG-4 airplanes is developed in MATLAB and the modeling results are analyzed.
TThe present paper proposes a model for evaluating geo-ecological protection technologies based on multi-criteria optimization and weighted convolution criteria, on the basis of which the method of calculation is developed, allowing to determine the PQ factor for different objects according to the selected technologies using the Mathlab environment. The work demonstrated the application of the technique in the case of materials made of ash foam concrete with densities and ash content from the incineration of sewage sludge. The determination of the optimum composition of solopenobeton is relevant for the design of noise shields in railway transport. The proposed simulation algorithm in the Matlab environment makes it possible to use the procedure of processing the raw data, using several options of their input: in the form of tables of the format. csv or manual input.
Soft independent modeling of class analogy (SIMCA) is one of the OCC methods widely used in chemometrics. The original version, proposed by S. Wold, has numerous modifications mostly related to the way of constructing the acceptance boundaries. Recently, authors proposed the data driven version of SIMCA (DD-SIMCA), which allows to calculate the errors of misclassification theoretically. In this paper, we present DD-SIMCA — a MATLAB GUI tool that extends the MATLAB® environment to provide an easy way for establishment and employment of the data driven SIMCA technique.
