Abstract
In this paper the synthesis of a rotational speed closed-loop control system based on a fractional-order proportional-integral (FOPI) controller is presented. In particular, it is proposed the use of the SCoMR-FOPI procedure as the controller tuning method for an unmanned aerial vehicle's propulsion unit. In this framework, both the Hermite-Biehler and Pontryagin theorems are used to predefine a stability region for the controller. Several simulations were conducted in order to try to answer the questions - is the FOPI controller good enough to be an alternative to more complex FOPID controllers? In what circumstances can it be advantageous over the ubiquitous PID? How robust this fractional-order controller is regarding the parametric uncertainty of considered propulsion unit model?

Abstract
Multi-stage manufacturing, typical in important industrial sectors, is inherently a complex process. The application of the zero defect manufacturing (ZDM) philosophy, together with recent technological advances in cyber-physical systems (CPS), presents significant challenges and opportunities for the implementation of new methodologies towards the continuous system improvement. This paper introduces the main principles of a multi-agent CPS aiming the application of ZDM in multi-stage production systems, which is being developed under the EU H2020 GO0D MAN project. In particular, this paper describes the MAS architecture that allows the distributed data collection and the balancing of the data analysis for monitoring and adaptation among cloud and edge layers, to enable the earlier detection of process and product variability, and the generation of new optimized knowledge by correlating the aggregated data. © 2018, Springer International Publishing AG.

Abstract
This paper presents the design of a robust pole placement controller for linear and time invariant systems described by models whose parameters are unknown but, with known bounds, using only plant, input, and output signals. The main objective is to locate the closed-loop poles within a region specified by an interval characteristic polynomial, chosen based on performance specifications and whose stability is guaranteed by Kharitonov’s theorem. The procedure to find a closed interval for each controller parameter is formulated us a nonlinear programming (NLP) problem and switching laws based on the variable structure adaptive pole placement control (VS-APPC) are used to estimate the unknown plant, parameters. This innovative strategy gives a fast, and non-oscillatory transient,, smooth control signal and robustness to large model parameter variations. Moreover, the constraints imposed by the interval controller meet the closed-loop performance requirements. Simulation results are presented for second order nonminimum phase plants, to illustrate the properties of the proposed technique. © 2017 ICIC International.

Abstract
This document covers the questions for students that participated in a mobility program, that are short-term students and full time students from different countries. With the central question being why mobility students choose Kauno Kolegija. It is the main goal to find out their opinion about the school starting with the question, what was their motivation to study in Kauno Kolegija. 53 students participated in the survey, being the majority of them Erasmus students. The data was obtained by a survey that took the form of an online questionnaire. This survey includes answers from EU and Non-EU students and it is based in a quantitative survey, which is after studied using graphical analysis program SPSS. The major objective of this research is to help Kauno Kolegija with the best information and results to provide the responsible people enough material to improve and increase the incoming students flow into the school from mobility studies and internships. Since the Erasmus program started the flow of students has been going up and down, having students from Turkey as 40% of the income, Kauno Kolegija will benefit with the results by understanding why East Europe and nearby countries has more incoming students than West Europe and be able to fight this unbalance.
