The paper presents the software concept of a data acquisition system used in vegetation status monitoring. The work focuses on finding a robust, adaptable and appropriate software architecture that can be used as a standard in the data capturing process in precision agriculture. A solution is proposed that provides a high degree of modularity and expandability, error management capabilities, a database...
This work introduces an ECG signal denoising method using discrete wavelet transforms. In the first part of the study, classical denoising methods were revised, tested and analyzed. To minimize signal distortion and resource usage the wavelet decomposition and thresholding was proposed. In the second part of the study, the methods mentioned above were used to remove the baseline wondering and high-frequency...
Locomotives reach a high value of tractive effort. The high values of tractive effort can cause problems if an adhesion conditions are poor. A wheel velocity high value that is much greater than the train velocity can occur in this case. The high slip velocity value has to be eliminated because it causes a high wear of wheels and rails and can cause damage to some locomotive mechanical parts. The...
The Bluetooth Low Energy technology has become more and more popular among wearable devices due to its low price and reduced power consumption. However, the development industry has oriented itself among mobile platforms neglecting the standard operating systems and providing only a limited set of integration possibilities most often using a smart-phone, restricting in this way the utility of such...
The objective of this paper is to present an algorithm for processing infrared images and accomplishing automatic detection and path tracking of moving subjects with fever. The detection is based on two main features: the distinction between the geometry of a human face and other objects in the field of view of the camera and the temperature of the radiating object. These features are used for tracking...
A new approach to the blood glucose concentration control problem is investigated in this paper. The solution implies the use of fractional-order calculus both for the plant's model and for the controller. A fractional-order model of the insulin-glucose system is derived from the well-known minimal model, by replacing the integer derivatives with fractional ones. Next, fractional-order calculus is...
The networked control systems (NCSs) have nowadays applications ranging from factory and home automation, to automotive and avionic control systems and to military and spatial applications. Their widely inclusion in the industry was mainly due to the inherent advantages, e.g. lower costs, simpler installation and maintenance, higher reliability and greater flexibility. Although the subject was extensively...
Genetic algorithms are probabilistic searching techniques that are able to provide results in complicated problems from various IT domains. The generated results depends directly by parameters of genetic algorithms operators (crossover and mutation probability, population size, number of generations, types of chromosomes, fitness function, etc.). In this paper it is proposed an adaptive type of crossover...
The article presents the identikit approach to requirements justification for design characteristics and evaluation of the flight capabilities of the next-generation vehicles. It is demonstrated that in the “question-answer” mode it is possible to effectively sort out various vehicles configurations options; dimensional and aerodynamic characteristics; onboard equipment, controls, communications and...
The paper discusses the challenges in front of the smart grids control and the possibilities for migration the new information and communications technologies for their overcoming. A model of distributed system for remote monitoring and control in substations is proposed. The hardware and software design are considered. Attention is paid on the use of PLCs as servers and gateways. Their application...
In this article one examine the topic of Building Information Modeling (BIM) from the perspective of the residential building' owners. We present a novel approach to estimate of energy consumption through the identification of the relevant parameters and the application of Soft Computing techniques.
The fact that extensive territories in the world facing lack of fresh water or dealing with limited quantities of water available for everyday use is determining developers to work out intelligent, microcomputer based watering systems. These systems are capable to control an irrigation network in such of manner that the maximum soil moisture in a desired location is achieved with minimum possible...
The 13C isotope separation column cascade system is a very rare and complex process which can become even dangerous if it is not operated in a proper manner. The development of an efficient supervisory and control system still represent a challenge due to the number of interconnections and interdependencies between the process variables. The objective of this paper is the development and the implementation...
An approach for systems integration and components of advanced technology under the changing landscape of the global energy economy is shown. The paper presents the basic procedure for determining the adaptive infrastructure solutions in the implementation of intellectual environment of multiaspect modeling (virtual semantic environment). The relevant techniques for systems integration and simulation...
Given the growing demands for network services based sometimes on reduced resources, efficient solutions are continuously developed in order to operate the network infrastructures in optimum conditions. From network management viewpoint, the main challenge is related to traffic management solutions using data flow limitations for some specific users while giving higher priorities to others. If for...
The tendency of any mobile technology is to automate as many of its processes. LTE (Long Term Evolution) introduces the concept of SON (Self-Organizing Network) that targets the automation of a large number of LTE processes. On the other hand, Peer to Peer (P2P) technology, even if it is used mainly in Internet and file sharing applications can bring significant improvements to LTE. This article discusses...
The paper presents a new prototype model car design devoted to provide a better study and research of the control techniques and navigation algorithms employed within vehicle platooning. The prototype car has a modular design and is equipped with various sensors. All the car parts were designed in a 3D CAD application and 3D printed. The embedded application designed to control the car behavior is...
The recent emergence of deep learning algorithms has radically influenced the object detection performances by providing very precise and robust approaches. However, the disadvantage of the recently proposed object detectors is that they are computationaly extremely intensive, making them unsuitable for being used in portable devices. In this paper we propose six models which optimize an existent...
Multimedia quality of experience (QoE) accounts for the degree of delight or annoyance of the user of an application or service. Although humans have five senses, only two of these senses (i.e., sight and hearing) are stimulated by traditional multimedia contents. Therefore, the research efforts try to add additional constituents for stimulating other senses, beside sight and hearing, like smell and...
Protection of information achieves keeping confidentiality, integrity, and availability of the data. These features are essential for the proper operation of modern industrial technologies, like Smart Grid. The complex grid system integrates many electronic devices that provide an efficient way of exploiting the power systems but cause many problems due to their vulnerabilities to attacks. The aim...
