Changes in the temperature of the medium significantly affect the static characteristics of hot-wire anemometry measuring wires, which causes errors in the results of flow velocity measurements. High temperatures of the medium make it necessary to additionally heat the sensor to even higher temperatures, which may lead to its damage due to wire bur...
Article
For measurement of two-dimensional flow velocity vector a special multi-wire measurement probe was used. Its design allows to determine magnitude, orientation and the sense of the flow velocity vector. The conducted research were related to the analysis of the possibility of using an artificial neural network for flow velocity vector measurements....
Article
In this paper a novel parallel algorithm for the tensor based classifiers for object recognition in digital images is presented. Classification is performed with an ensemble of base classifiers, each operating in the orthogonal subspaces obtained with the Higher-Order Singular Value Decomposition (HOSVD) of the prototype pattern tensors. Parallelis...

The use of measurement apparatus under conditions which differ significantly from those under which the apparatus was adjusted carries the risk of altering the previously determined measurement characteristics. This is of special concern in the case of apparatus which is sensitive to external measurement conditions. Advanced measurement systems are...
Article
In this paper we present architecture and functionality of the visual multi-tool designed for acquisition of ground-truth and reference data for computer vision experimentation. The multi-tool allows three main functions, namely manual matching of the corresponding points for multi-view correlation, outlining of the image objects with polygons, as...

Computationally Efficient Methods of Approximations of the S-Shape Functions for Image Processing and Computer Graphics Tasks The paper describes a number of methods for approximation of the S-shape functions, frequently used in computer graphics or image processing. The main focus is on efficient software and hardware implementations. We present o...

The balance of mass or volumetric flow of air in ventilation systems may be carried out on the basis of the flow velocity field assessment. The minimization of the measurement error of such a measurement requires the application of a method allowing for determination of the magnitude, direction and sense of the velocity vector in examined points of...
Article
Three types of hot-wire anemometric probes for the measurement of a two-dimensional flow velocity vector and its sense are presented in this paper. Such probes are a modification of type X hot-wire probes, in which additional supports are introduced in the middle of wires. The idea of the sense of a flow velocity vector assessment is based on the p...
Article
Hot-wire measurements of velocity vector components use a sensor with three orthogonal wires, taking advantage of an anisotropic effect of wire sensitivity. The sensor is connected to a three-channel anemometric circuit and a data acquisition and processing system. Velocity vector components are obtained from measurement signals, using a modified a...
