The use of wireless technologies and low-capacity devices is now inevitable in smart spaces development for Internet of Things (IoT). A smart space is created by deploying a Semantic Information Broker (SIB) on a host device. This paper examines the applicability of a wireless router for being a SIB host device and creating a smart space in the IoT environment. CuteSIB is one of SIB implementations...
The paper presents a deep analysis of the literature on the problems of optimization of parameters and the structure of the neural networks and the basic disadvantages that are present in the observed algorithms and methods. As a result, there are suggested a new algorithm for neural network structure optimization, which is devoided of the major shortcomings of other algorithms. The paper includes...
Current study performs a comparison of the contour inflection point selection methods according to the following criteria: probability of the correct selection, probability of the incorrect selection and an error in the coordinate estimation based on the results of model tasks. Results of the interpolation and differential methods and the method based on wavelet analysis of the contour inflection...
In recent years, mobile cyber physical systems have found applicability in multiple areas such as mobile intelligent robots and robotics systems, intelligent transportation systems, environmental monitoring systems, healthcare systems and so on. Remote control of mobile objects is a very promising field which allows to improve the convenience and safety of human society life. According to the fact...
Cognitive systems are a perspective object for distance learning. Futurologists talk about the massive use of cognitive systems in one or two decades. Remote laboratories are an important element of distance learning systems. Currently, these laboratories are used to study information control systems and require development and improvement to study cognitive systems. A refined structure of the cognitive...
The asymmetry of skin lesion is one of the three-point checklist (3PCLD). The 3CPLD is depending of a shape, hue/color and structure of the lesion. In the paper, a dermatological asymmetry measure in hue (DASMHue) is presented and discussed. The hue distribution asymmetry of the segmented skin lesion is discussed and new dermatological asymmetry measures of hue distribution are defined. One of the...
As the in-door navigation system are real-time systems they provide variety of tasks for teaching in the field of reliability, which should be considered simultaneously from hardware and software. In the article authors consider tasks, which should be solved for the location detection for the in-door navigation systems, metrics which can be used for reliability assessment of these systems and the...
The article presents the results of studies of the physical security system in the infrastructure facility of a region. The following results have been obtained: structural and functional decomposition of the physical security system for the regional infrastructure has been performed; engineering solutions for the implementation of the standard functions for the subsystems of the research object have...
Diversity and subdiversity-oriented systems applied in safety critical industry systems are analyzed through the use of the classification scheme described in standard NUREG7007. This classification is specified considering diversity of hardware and FPGA designs. In particular, diversity of hard logic and soft processors, interfaces and buses, self-diagnostics means, etc… are described. Impact of...
Housing consumption keeps growing in spite of energy efficient devices. The problem seems to come from not only the lack of information about how to use these devices but also from the lack of willingness from inhabitants. This double assessment invites to think about support toward inhabitants' behaviors concerning to energy consumption, which is affected by both devices and values. The paper follows...
Water management and irrigation scheduling have become the main subjects of different studies in the last decades, due to their high influence on crop performance indicators. This study presents the most important parameters that have to be monitored in an irrigation management system and the most important ones are synthesized: air moisture and temperature, soil air and moisture, evapotranspiration...
The specification of the Transport Layer Security (TLS) protocol defines its own presentation language used for the purpose of semi-formally describing the structure and on-the-wire format of TLS protocol messages. This TLS Presentation Language (TPL) is more expressive and concise than natural language or tabular descriptions, but as a result of its limited objective has a number of deficiencies...
This paper presents the closed loop teleoperation of a minimal surgery training system using haptic and robot devices. The force tracking performances of system can be improved by using dynamic compensation and fuzzy control. In this system, the master is the 6-DOF haptic device and the slave is the 6-DOF serial robot. The master haptic device provides the trajectories for the slave serial robot throught...
In the paper, the communication security is discussed. Nowadays applications mainly do not support end-to-end security. The enhanced SDEx cryptographic method and analysis of its security and the analysis of its robustness are presented. The analysis is focused on statistical randomness tests proposed by NIST. These tests are derived in order to check the randomness of the ciphertext and are often...
The process of human adaptation to the Arctic conditions is accompanied with changes in psychophysiological indicators such as strength and mobility of nervous processes. Extreme conditions have a strong impact on a human brain. This effect is different for people with different laterality. Laterality indicates functional asymmetry of two brain hemispheres. The authors propose software-based evaluation...
Clustering analysis is an active research branch in the area of data mining due to its simplicity and rapidity. However, K-means algorithm has the shortcomings of heavily depending on the initial clustering center and easily falls into local optimum. In this paper, we consider a deep research on K-means algorithm of optimization. We put forward the first selected initial clustering center of K-means...
