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.

The paper presents a novel method of fault location and the calculation of transverse impedance of a fault in a damaged medium voltage cable. The method is based on the measurement of input impedance at one end of the cable with an open and short circuit state at its other end with appropriately selected frequency. The obtained results were compared with those obtained by means of the reflectometer. The effectiveness of the method was verified numerically and experimentally.

There is need to replace the traditional materials used in mechanical constructions with cheaper materials characterized by high durability and simplicity of manufacturing. An alternative technology is 3D printing technology that uses ABS material (poly (acrylonitrile-co-butadiene-co-styrene)). 3D printing technology ensures the rapid change of model dimensions and shapes at the prototyping stage and a relatively cheap cost of new elements. There are many plastic materials producers on the market for a 3D printer. In this paper two of them have been choosen to a comparison and their mechanical parameters have been determined. The modal analysis of this material was carried out and the obtained values of resonance frequencies were compared.

Modem mobile devices, such as smartphones and tablets, are offering a wide range of entertainment applications that require an increasing amount of computational and storage resources. To address such needs, developers transfer the load from the mobiles to remote resources, usually in a Cloud infrastructure. The focus of our work is to find policies for balancing the load between devices and remote resources using offloading techniques. We apply these techniques on a popular artificial intelligence intensive mobile game, OpenTTD and seek to reduce the server-side load by leveraging the devices computing capabilities.

This paper addresses the problem of automaticcontrol of the blood pressure in post cardiac surgery patients. The focus of this study is on showing that reinforcement learning may be suitable for the blood pressure regulation in post cardiac surgery patients, using directly the clinical data, without the need of an accurate patient model. A detailed and realistic model of a hypertensive patient is successfully developed and implemented. Firstly, we use this model in order to create closed loop control with a classical PID controller. Secondly, we use the model only as a source of pseudo-clinical data with reinforcement learning.

In this article it is proposed and designed a modern control configuration of the type multicontroler-multimodel (MM) that pilots the nonlinear combustion process of the Diesel engine, needed to adjust the pressure in the intake manifold and the airflow circulating through the compressor. The MM simulator developed by the authors allows the implementation of control systems represented by pairs (Mi, Ci) with the Mi candidate closest to the current operating point of the process and the paired controller Ri, for controlling the key parameters of the combustion process. The proposed configuration is built with robust controllers and thus it is able to ensure superior performance, tolerance to nonlinearities and parametric and structural perturbations in the system.
