this paper presents the architecture of the non-contact sensor for measuring the rope swinging angle in two planes. the sensor were dedicated to the all kind of the crane device, especially to overhead travelling crane. the main objective of this statement applies a solution for improving early developed and described non-contact vision swinging sensor. In the article, the author main attention has been focused on issues related to the possibility of using a "smart camera" device as a full functional contactless two-dimensional sway sensor. All tests and considerations were conducted on the scaled physical model of overhead travelling crane with hosting capability 150kg.
We address the magnetic-field simulteanous localization and mapping (SLAM) problem for global positioning. We leverage a previously-developed particle filter (PF)-based framework for online Bayesian inference and lear...

this paper presents a new concept for modeling of linear fractional-order dynamical systems. the proposed model is based on specific basis functions, the so called Fractional-order Difference Basis Functions, which are a generalization of the delayed filters used in the FIR model. In the paper, we show elementary properties of the model and present a method for model implementation. Simulation example shows that the model can be effective in modeling of a class of dynamical systems.
the paper deals with a cross-docking problem which is an example of real-word logistics problem and belongs to the class of NP-hard optimization problems. Cross-docking is a transshipment platform, where products from...

the effect of vignetting is undesirable in image processing and analysis. It cause fall-off of pixel intensity from centre towards edges of the image. In this paper, we propose a new procedure of fast vignetting reduction based on two images acquired with different camera/lens settings. the change of lens aperture or focal length will also change the effect of vignetting in images. these differences are used to estimate a vignetting function, which is used for vignetting reduction. the obtained image after vignetting reduction is not significantly different from the image without vignetting.

the stability problem of fractional discrete-time linear systems with delays has been analysed. the state-space model with a time shift in the difference has been considered. New necessary and sufficient conditions for the asymptotic stability and the practical stability have been established. the systems with only one matrix have been also analysed. It has been shown that such systems are asymptotically (practically) stable if all eigenvalues of the state matrix lie in the stability region of the complex plane.

In the paper we consider a coupled problem of the linearly elastic body immersed in the flowing fluid which is modelled by means of incompressible Navier-Stokes equations. the approach is based on transforming the variable domain occupied by the fluid to the fixed one corresponding to the un-deformed elastic inclusion. the main idea consists in performing the linearisation of this transformation, similarly as in linear elasticity one assumes the smallness of strains. We base our approach on the observation that the gradients of the suitably defined transformation are bounded by traces of strains on the surface of the elastic body.

the use of an Electrical narrow tilting car instead of a large gasoline car should dramatically decrease traffic congestion, pollution and parking problem. the aim of this paper is to give a unique presentation of the geometric modeling issue of a new narrow tilting car. the modeling is based on the modified Denavit Hartenberg geometric description, which is commonly used in robotics. Also, we describe the special Kinematic of the vehicle and give a method to analyze the tilting mechanism of it. Primarily experimental results on the validation of the geometrical model of a real tilting car are given.

this paper presents the determination of optimal reduction parameters for complex models of the Rational Krylov methods with using Evolutionary Algorithm. the presented algorithms facilitate a precise reduction of linear time invariant, multi-input and multi-output models. the elaborated algorithms are particularly significant for MIMO models, for which the individual channels differ significantly from each other. the prepared algorithms have been applied for the reduction of the subsystems models of a BP-1150 steam boiler.
