Key Words: Gas sensors; gas sensors array; electronic nose; food; quality control; sunflower oil.

Abstract. Тhis work presents a study and identification of oil through multisensor system electronic nose. The system is built on the basis of eight gas sensors, reacting to different types of gas. With the help of the system, a study of sunflower oil produced from pressed sunflower seed and extrusion of oil cake (the remainder of the primary pressing) was carried out. The data obtained from the study is used to train an artificial neural network. After the training, artificial neural network successfully recognizes the test sample.

Key Words: Emotion recognition; emotion detection;intelligent agents; multimodal analyses;multilayered architecture.

Abstract. The paper presents different approaches for emotion detection and recognition. A system infrastructure for emotion recognition is suggested based on a multilayered multimodal architecture with intelligent agents. The agents have diverse goals, utilizes different modalities and employ various algorithms for emotion detection and recognition. Based on the results of the agents’ operation a neutral model of the multimodal input data is generated that is used for emotion recognition by detecting deformations with respect to the reconstructed model. The proposed system infrastructure allows autonomous operation, utilization of the most suitable recognition algorithms for certain input data and generation of neutral models for the examined object.

Key Words: Blockchain; education; behavior tracking; distributed networks; e-learning.

Abstract. In this article, we are going to introduce a model for integrating an intended interface platform for storing information regarding the behavior of students, over a blockchain network. The state of the art will describe the actual concept of the technology and the main article will introduce the in-dept architecture of a software prototype UniChain a distributed clause based blockchain network for storing behavior information. The main purpose of the article is to address a practical approach for implementing a theoretical concept over education and to propose an implementation solution for a real-world problem.
