The paper describes the development of a piece of software called “SimplexAlgo”, which calculates and solves a simplex algorithm. We have created this software for educational purposes in linear programming, which is a technique for the optimization of a linear objective function, subject to linear equality and linear inequality constraints, and as such is widely used in many fields in operation research. SimplexAlgo has been developed with the C# programming language in Visual Studio desktop. To execute an exercise, the software is manually coded according to the methods and ways studied and learned. To achieve the desired result, various attributes are used, as well as network connections from where we get the steps of a function (step -step-step). The application has a special algorithm to solve an exercise and provide solutions. Comparisons have been made regarding the speed of execution of the algorithm of this software with the existing ones, where it has been established that the execution time is faster.

This article describes a mesh wireless sensor network that manages the lighting of large buildings and areas that allow separation of individual sectors within them. If there are no visitors in any of the sectors, the system turns off the lights in them and thus saves electricity. When any visitor appears, the system activates the lighting in the corresponding sectors and in the adjacent ones, thus preserving the comfort of the vision and the visitor is left with the impression that the whole area is fully illuminated. Apart from being a green technology, this approach provides additional benefits, such as easier guarding of open spaces and buildings with windows in the dark hours. The components used are easily available and allow for budget and, at the same time, efficient implementations.

The aim of this paper is to create a model for predicting heart failure mortality using the decision tree method, and to apply it to a specific set of information using the RapidMiner data analysis platform. Due to the rapid pace of medical development, there is an urgent need to provide recommendations derived from filtering the entire set of medical data. It becomes difficult for patients to make the right decision due to the huge variety of treatments and ways to improve their lifestyle. This necessitates the emergence of predictive methods that aim to offer the patient the most accurate choice according to specific complaints instead of wandering among multiple random choices with varying degrees of significance in reality. Event prediction methods extract the most vital information from a huge data set, “reading” the patient’s problems and suggesting the most appropriate treatment for him/her. Most patients are late in taking the necessary care of their own health, and they realize the importance of prevention at a later stage. If every person could predict what might happen to him/her later in life, he/she would be much more cautious and make more timely efforts for his/her health. The need for decision-making in clinical practice often has important long-term consequences.

The paper examines the technologies for creating digital educational resources from the point of view of necessity, implementation, and techniques for their creation. Various digital educational tools and their capabilities according to their application are described: learning and learning management programmes, tools for creating online tests and surveys, tools for creating online quizzes and educational games, interactive worksheets, tools for video lessons, OneNote electronic notebook. A study was conducted on the opinion and attitude of teachers and students about the electronic resources used in different academic disciplines, both for teaching learning content and for control and self-control. The results of two surveys are presented – one aimed at students and the other at teachers. The opinions of 155 teachers and 180 students from four regions in Bulgaria are summarized. The two main aspects of an application – for teaching learning content and for control and self-control – have been analyzed.

The COVID-19 pandemic imposed a quick introduction of distance learning for many students. In Bulgaria, the Ministry of Education and Science obliged schools to work synchronously with their pupils using video conference rooms. After the easing of the containment measures, regular classroom education was restored. However, the problems with quarantined students persisted. School principals had to solve new organizational challenges. The hardest and most frequent issue was the split of a given class into students present in school, and students learning online. The article introduces an organizational model of a hybrid classroom where teaching is carried out in a physical and an online classroom at the same time. The authors describe their experience with specific hardware and software used for the first time in Bulgaria for educational purposes. They also show their experience with the organization of traineeships for university students as primary school IT teachers using a hybrid classroom.

Raising the level of digital education is one of the main challenges facing the education system now and in the future. The use of modern technical means in the learning process is an important prerequisite for achieving this ambitious goal. However, this must go hand in hand with the introduction of new scientific methods and teaching approaches. This article presents different approaches which the author has applied in her practice with high school students. It proves the benefit of their implementation in the educational process.
