The paper presents the application of the linearizing control technique for stabilization of the isopropanol concentration in the ultrasonic nebulization process. The isopropanol concentration has to be kept constant to make the nebulization process more efficient. This is achieved by manipulating the inlet flow rate of a fresh isopropanol-water mixture. Because the content of the vessel is not well-mixed, it was shown that by measuring only the isopropanol concentration at the bottom of the vessel, the control system performance could be improved by the optimal selection of controller parameters. Moreover, the simulation results have show n that the closed-loop system was stable and exhibited similar behavior, even if the nebulization rate was not know precisely.

As computer Supported Collaborative Learning (CSCL) gains a broader usage as a viable alternative to traditional educational scenarios, the need for automated tools capable of evaluating active participation and collaboration among peers in online discussions increases. In this study, we validate a quantitative model of predicting involvement in CSCL chats based on student's pauses throughout the timeline of the conversation. Starting from a corpus of 10 chat conversations, our proposed model explains 55% of the variance in terms of student participation and 42% in terms of collaboration, although relying on simple quantitative indices.

A concept of the porous core electromagnet is studied. The form for the electromagnet core was printed using 3D technique. The core was manufactured manually using iron filings and cured in room temperature and air pressure. The aim of this paper is to deliver initial analysis of the proposed powder core together with the modelling procedure by the using finite element method, and to compare the experimental results of the manually manufactured electromagnet. The material property of the numerical model was adjusted to fit the experimental results. Finally, the electromagnet was tested in the levitation real–time experiment.

In this paper, we derive recursive algorithms for calculating the inverse of the generalized Vandermonde matrix. The main advantage of the recursive algorithms is the fact that the computational complexity of the presented algorithm is better than calculating the inverse by means of classical methods, developed for the general matrices. The results of this article do not require any symbolic calculations and therefore can be performed by a numerical algorithm implemented in a specialized or general purpose programming language.

In this paper we present counterintuitive examples on the influence of strong, positive autocorrelation of network traffic on some of the queueing characteristics in network nodes. In particular, it is shown that the average queue size can sometimes be significantly shorter in the case of autocorrelated traffic than in the case of the uncorrelated one, even if the service time and load are the same in both cases.
