Graph Generation

The subject of the research is one of the ways of updating modern training systems for solving problems of graph theory, namely, automatic generation of graphs. This approach will reduce the load on the training system database and generate tasks for the user in real-time without updating the bank of tasks. In the course of the work, the advantages and disadvantages of this approach were identified. The most suitable method for the implementation of the research was chosen to represent graphs in electronic computers. The requirements for generated graphs and possible ways of implementing these requirements are identified and substantiated. Namely: in the implemented program, simple connected undirected graphs will be generated. We considered an important detail in working with graphs — graph traversal using the “Depth (width) search” algorithm, which in this task is used to check the graph for connectivity. The result of the work is presented — a software implementation of the graph generation algorithm in the C# programming language. In it, graphs are represented by an adjacency list, generated randomly, and checked for connectivity using the DFS (Depth First Search) function. DFS is a software implementation of the Depth First Search algorithm.

And Training

Computer based teaching and training systems in general, and Intelligent Tutoring Systems (ITSs) in particular, are usually based on similar fundamental structures. In contrast to this, analyses of the state of the art of teaching and training system development have revealed that software engineering techniques are seldom used for realizing those systems. In the last years, some approaches tried to change this: pattern mining took place; methods covering the specifics of ITS project development have been deployed. These approaches usually focus on a specific system type or on a certain application domain, thus re-usability is often not possible. What is missing is a combination of different approaches in a pattern language or a pattern catalogue for ITS. The purpose of such a pattern catalogue is to provide pattern for different types of software and to support the software development starting from design and ending with the implementation. A step towards a pattern language for ITS is described in this paper.

Abstract Distance learning and e-learning have significantly developed in recent years. It is also due to changing educational requirements, especially for adults. The article aims to show the advantages and disadvantages of distance learning. Examples of the 20-year use of the distance learning form of computer science describe the difficulties associated with the implementation and implementation of this form of teaching. The results of students in the full-time and distance form of teaching in the bachelor’s study of computer science are compared. Long-term findings show that distant students have significantly lower scores in the first years of study than full-time bachelor students. In the following years of study, the differences diminish, and students’ results are comparable. The article describes the possibilities of improving the quality of distance learning.

<p>Computer assisted and computer based applications become more and more important in everyday lives. Their implementation in the field of music education seems to become a long-term project. Whereas years ago we were sure about the fact, that the quality of e-learning at our University of Music and Performing Arts depends on the implementation of audio-visual media at our e-learning platform, nowadays the text based tasks and written journals have won the race at least in the statistic of usage. </p><p>Many modules containing multimedia based content promote creative processes and different learning situations. Advantages of e-learning include flexibility and convenience for learners, especially if they have more variety in learning experiences by using multimedia applications. This paper deals with the change of our user behaviors in the last years, discussion forums, blogs, wikis and collaborative online activities and focuses on tools for musicians, composers and music scientists based on the actual status of the discussions in media pedagogies. A scientific project including surveys about the advantages and disadvantages of digital teaching repositories describes common used online music tools. </p><div><span><strong><br /></strong></span></div>

In this article, we present a taxonomy in Robot-Assisted Training; a growing body of research in Human–Robot Interaction which focuses on how robotic agents and devices can be used to enhance user’s performance during a cognitive or physical training task. Robot-Assisted Training systems have been successfully deployed to enhance the effects of a training session in various contexts, i.e., rehabilitation systems, educational environments, vocational settings, etc. The proposed taxonomy suggests a set of categories and parameters that can be used to characterize such systems, considering the current research trends and needs for the design, development and evaluation of Robot-Assisted Training systems. To this end, we review recent works and applications in Robot-Assisted Training systems, as well as related taxonomies in Human–Robot Interaction. The goal is to identify and discuss open challenges, highlighting the different aspects of a Robot-Assisted Training system, considering both robot perception and behavior control.

The objective of this paper is to provide necessary information when selecting the capability for the speeding process of solving the computation problem. The main features implemented using the following models are described: programming in systems with shared memory, programming in systems with distributed memory, and programming on graphics accelerators (video cards). The basic concept, principles, advantages, and disadvantages of each of the considered programming models are described. All standards for writing programs described in the article can be used both on Linux and Windows operating systems. The required libraries are available and compatible with the C/C++ programming language. The article concludes with recommendations on the use of a particular technology, depending on the type of task to be solved.

Abstract: The objective of this work was to compare the effect of the Y-trellis and vertical shoot position trellis (VSP) training systems on the physicochemical composition and aromatic profile of 'Sauvignon Blanc' (Vitis vinifera) wines in a high-altitude region of the state of Santa Catarina, Southern Brazil. The experiment was conducted during the 2015 vintage in a commercial vineyard located in the municipality of São Joaquim. The treatments consisted of the training systems: Y-trellis and VSP pruned in spur cordon. Sixty kilograms of grapes were harvested from each training system to make the wines, which were evaluated as to their chemical and phenolic composition and aromatic profile. There is no effect of the training system on the wine chemical variables pH, total acidity, color, and total polyphenols. The aromatic profile and phenolic composition of the wines are affected by the training systems, being related to the variables ethyl acetate, isoamyl acetate, 3-methyl-1-butanol, propanoic acid, and gallic acid in the Y-trellis, and to 1-hexanol, isovaleric acid, caprylic acid, capric acid, and catechin in VSP. The Y-trellis system can be an alternative for high-altitude regions of Southern Brazil.

The aim of this study was to evaluate phenology aspect, vigor, production and quality of ‘Eragil’ peach trees grown under different training and pruning systems. Evaluations were carried out during two seasons, 2015/16 and 2016/17. Fruit tree training and pruning systems ‘Open Center’ (3.5 × 5.0 m), ‘Ipsilon’ (1.5 × 5.0 m) and ‘Central Leader’ (0.8 × 5.0 m) were used. Phenology, vegetative growth (vigor) and yield were evaluated. ‘Central Leader’ plants showed a higher productivity and productive efficiency. ‘Open Center’ plants had a greater vigor and yield per plant, however had a lower yield by unit area. Plants with ‘Y’ shape were intermediates between ‘Open Center’ and ‘Central Leader’ in relation of the evaluated variables. ‘Central Leader’ training system can be used for peach orchards in order to increase yield and productivity indexes.
