Thanks to the exponential growth of the Internet, Distance Education is becoming more and more strategic in many fields of daily life. Its main advantage is that students can learn through appropriate web platforms that allow them to take advantage of multimedia and interactive teaching materials, without constraints neither of time nor of space. Today, in fact, the Internet offers many platforms suitable for this purpose, such as Moodle, ATutor and others. Coursera is another example of a platform that offers different courses to thousands of enrolled students. This approach to learning is, however, posing new problems such as that of the assessment of the learning status of the learner in the case where there were thousands of students following a course, as is in Massive On-line Courses (MOOC). The Peer Assessment can therefore be a solution to this problem: evaluation takes place between peers, creating a dynamic in the community of learners that evolves autonomously. In this article, we present a first step towards this direction through a peer assessment mechanism led by the teacher who intervenes by evaluating a very small part of the students. Through a mechanism based on machine learning, and in particular on a modified form of K-NN, given the teacher’s grades, the system should converge towards an evaluation that is as similar as possible to the one that the teacher would have given. An experiment is presented with encouraging results. Copyright 2018 by SCITEPRESS – Science and Technology Publications, Lda. All rights reserved

Systems are often controlled using feedback loops. Fault diagnosis schemes are usually designed assuming that there is no feedback loop. Therefore fault diagnosis methods need to accommodate for the feedback loop. One such method is active fault diagnosis based on a fault signature system. This method is derived using the YJBK parametrisation, named after Youla, Jabr, Bongiorno and Kucera. It uses the derived fault signature system to determine the detectability of possible faults in the system. Deriving the fault signature system requires knowledge about the controller. This paper demonstrates the possibility of estimating the detectability of faults in the fault signature system using a gap-metric. The gap-metric has the advantage of only requiring knowledge about the plant. By using the gap-metric it is possible to estimate the detectability of faults without using information about the controller. © 2018 IEEE.

This study aims to develop an online Greek language learning platform via a learning management system based on the WordPress platform for primary school pupils with Russian as a mother tongue. The subject was chosen with a view to aid both the communication needs of Russian native speakers in Greece, as well as their smooth integration into society. For the purpose of the current study, we investigated how Greek language is learnt in Russia, how widespread and popular it is, whether it is supported by the Russian educational system, as well as whether Greek language distance learning could be achieved. Moreover, LMS(Learning management system) environments were investigated as well, aiming at selecting the most student/teacher-friendly one. Taking into account that the platform is addressed to children, a presentable and properly developed material was designed, thus making the learning of each module more interesting and comprehensible throughout its short duration. With"GrfKids" platform speakers of other languages have the opportunity to learn Greek in an interactive asynchronous teaching environment with an automatic assessment. Moreover,"GrfKids" can be easily and immediately expanded both to pupils‘linguistic, as well as age range."GrfKids" provides Greek language courses to children with Russian as a mother tongue with interactive modules in which the learners can adapt the learning time by themselves. It is easy to use, functional and easily adapted to the ages it is addressed to. It was developed to create a teaching system by applying different plugins to the selected CMS(Content Management system), aiming to achieve a curriculum in which the pupil is in direct interaction with the educational material. It can be used individually, or as a support tool in a real class context. The curriculum has been designed in an evolutionary format and there is an introduction in each module explaining the part that follows. Copyright © 2019, The Authors. All rights re

The method of detection and localization of design errors in HDL-models of finite state machines with arbitrary output functions was proposed. The diagnostic experiment is carried out bypassing all arcs of the Mealy machine, starting from the initial vertex, including for machines of the "non-exclusive" class. To ensure the return of the machine with a possible design error in the initial state, it is suggested to use synchronizing sequences. Diagnostic experiments were performed in the Active-HDL design environment.

The paper studies the problem of determining the optimal control when singular arcs are present in the solution. In the general classical approach the expressions obtained depend on the state and the costate variables at the same time, so requiring a forward-backward integration for the computation of the control. In this paper, sufficient conditions on the dynamics structure are provided and discussed in order to have both the control and the switching function depending on the state only, so simplifying the computation avoiding the necessity of the backward integration. The approach has been validated on a classical SIR epidemic model. Copyright © 2018 by SCITEPRESS – Science and Technology Publications, Lda. All rights reserved

UKACC International Conference on control (control)

作者： J A Rossiter Dept. Automatic Control and Systems Engineering University of Sheffield UK

Laboratories are a core part of any engineering degree, but access to laboratories is typically limited due to a combination of timetable, space and equipment restrictions [1]. In more recent years that has been a significant growth in so-called virtual laboratories (VL), that is laboratory like activities that can be accessed via software or even a web interface, e.g. [2], [3], [5]. The advantage of VL is that the accessibility can potentially be improved to 24/7 and often these may be available on a student's own computing device thus also giving no space restrictions. Improvements in accessibility mean that staff can integrate VL far more easily into the curriculum and student independent study schedule with the consequence that, in principle, students can learn more effectively.

Many tracking systems are based on the Global Positioning System (GPS), Global System for Mobile communications (GSM) and smart phones, due to their wide availability and reliability. A moving object to be tracked, it sends its GPS coordinates to the observer via SMS. However, the economic feasibility of these systems mainly depends on the total cost of the used SMS messages. In this paper, an economic tracking scheme is proposed to reduce the tracking cost. A GPS-GSM tracking system that uses the proposed scheme is implemented and tested together with two classical tracking systems under two practical test cases. The first test case is a 121 km vehicle trip and the second is a 2.4 km walking journey. The results showed the effectiveness and economic feasibility of the proposed system, which achieved a saving in tracking cost up to about 64% with respect to the tested classical systems. © 2018 IEEE.

Machine and reinforcement learning (RL) are increasingly being applied to plan and control the behavior of autonomous systems interacting with the physical world. Examples include self-driving vehicles, distributed sensor networks, and agile robots. However, when machine learning is to be applied in these new settings, the algorithms had better come with the same type of reliability, robustness, and safety bounds that are hallmarks of control theory, or failures could be catastrophic. Thus, as learning algorithms are increasingly and more aggressively deployed in safety critical settings, it is imperative that control theorists join the conversation. The goal of this tutorial paper is to provide a starting point for control theorists wishing to work on learning related problems, by covering recent advances bridging learning and control theory, and by placing these results within an appropriate historical context of system identification and adaptive control.
