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.
As the Internet of Things evolves, many devices that were not previously considered suitable for this trend can now be used as a part of smart interconnected systems. This paper describes the process of adapting a Cis...

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.

The paper presents preliminary results for on-line measurement method of isopropanol concentration in the ultrasonic nebulization process using BW-Tek compact UV/Vis spectrophotometer. The experimental setup with nebulization vessel was constructed with a probe for on-line measurements. The tests were performed using a standard mixture of isopropanol and water with the volume isopropanol concentration in the range 19% to 83%. The results of on-line spectrophotometric method were verified using stationary spectrophotometer and a gas chromatography method. Linear calibration for the obtained data was performed and measurement uncertainties for the tested method were evaluated as confidence intervals.

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.
