This paper proposes a new effective algorithmic basis for solving the problem of choosing the permissible deviations of the parameters of the elements, choosing the measured currents and diagnostics of the electrical device elements. The algorithms developed by the authors are based on the new modification of the Gaussian elimination method to solve the systems of linear algebraic equations. One of...
The issues of software and hardware development are considered of data logging into systems of testing complex objects. The describes the architecture of a system for testing complex scientific-technical objects. In the list of original elements of the concept of building highly reliable, fast-reconfigurable interactive test monitoring and control systems: — using of original technology of representation...
Shorter innovation cycles along with the demand for individualized, high-quality products pose high challenges on today's automated material flow systems. These systems, suitable for producing bulk goods, but inflexible in case of product changes, need to react flexibly to unplanned configurations. Especially in the software domain retroactive adaptations are tedious work and prone to errors. By deploying...
This paper presents the ongoing work of applying the project-based learning approach to teaching IoT technologies in an advanced embedded networking course, which is offered to electrical and computer engineering students. The emphasis of this course is on teaching the prominent wireless networking technologies IEEE 802.11 (WiFi) for the IoT and the development of the IoT applications. Microcontrollers...
All vehicles produced today must be fitted with an On-Board Diagnostic (OBD) interface. With the help of the OBD a data connection through the Controller Area Network (CAN) is realized with the Engine Control Unit (ECU). This control unit is instrumental in optimizing the engine performance. There are many OBD adapters on the market today, ranging from the cheap Do-It-Yourself kind to expensive, professional...
We present a virtual system for strengthening of lower limbs focused on children with cerebral palsy, in the implementation we use sensors that allow to obtain the angular velocity and rotation of direction of the bicycle, for the design of the virtual environment we use the Labview software, in which two scenarios of different difficulty are created to visualize in virtual form the trajectory that...
This article presents the design of a telecommunications network that allows the monitoring of mud, earth, rock and debris flows produced by slope overflows in the main arterial roads of the city of Cuenca, Province of Azuay. This network is integrated in a system of monitoring of the SIS ECU 911 of the City of Cuenca. The system has been conceived as a set of devices such as wireless modules and...
The rapidly growing software content within the vehicles continue to make automotive systems more intelligent through the addition of software enabled electronics. A plethora of change in the automotive industry is largely driven by the embedded software technology. The Advanced Driver Assistance Systems are one of such innovations of technology which are gaining widespread momentum in today's ever...
Collecting and using user feedback as a method to support requirements engineering, might undermine user rights. This becomes apparent when looking at related areas, e.g., research in user experience, where collecting user feedback also plays an important role. In such settings, researchers need to ensure that the stakeholders' rights and integrity are respected. This paper identifies and discusses...
To provide efficient and effective mechanism for the network management it's necessary to create unified and flexible tool, independent from hardware solutions. Such tool could be set of policies, which control the behavior of radios, using predefined languages and parameters.
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...
Context-aware applications adapt their behavior based on collected contexts. However, contexts can be inaccurate due to sensing noise, which might cause applications to misbehave. One promising approach is to check contexts against consistency constraints at runtime, so as to detect context inconsistencies for applications and resolve them in time. The checking is typically immediate upon each collected...
The paper presents experimental research related to pH measuring and to the design of a system of pH monitoring. The paper is structured on three parts. The first part presents the principle of measuring the pH of a solution matter, the transducer structure and of the adaptor used. The second part is dedicated to the experimental research effectuated aiming at the use of PACTware software environment...
Multilevel system architecture of energy efficiency management in the region is developed in this work. The architecture model consists of three levels, namely, level of data collection and management of executive mechanisms, level of control and management of technological process, and level of operator control and formation of administrative decisions. Hardware and software of each hierarchical...
With the constant advances in wireless technology, radio spectrum has become a very scarce resource. Cognitive Radio (CR) has emerged as a viable way to deal with our inefficient use of the radio spectrum by utilizing unused spectrum holes or white spaces, as they are referred to. Using Software Defined Radio (SDR) we are able to realize CRs and their unique properties. Most of the research that has...
Article deals with the automated dispatch control system (ADCS) is designed to improve the reliability and efficiency of operational dispatch and process control facilities that are part of the power system. ADCS is a set of hardware and information of the software used in the dispatching management of energy facilities based on computer. The proposed model of simulator ADCS and automated system commercial...
In the next future, IoT systems will be “ubiquitous” and “pervasive”, bringing several benefits to mankind and also many issues about interoperability, security and privacy. The intrinsic vulnerabilities of IoT devices, with limited resources and heterogeneous technologies, together with the lack of specifically designed IoT standards, represent a fertile ground for the expansion of specific cyber...
Internet of Things is deeply integrated into all aspects of human life. This is also the case in higher education as well. Introduction of different e-learning tools requires from teachers and students deep knowledge in new emerging techniques. In the article we describe a project oriented approach in studying and 3 case studies on how new technology can improve the e-learning environment in HEIs.
This paper investigates the suitability of employing various measurable features derived from multiple wearable devices (Apple Watch), for the generation of unique authentication and encryption keys related to the user. This technique is termed as ICMetrics. The ICMetrics technology requires identifying the suitable features in an environment for key generation most useful for online services. This...
Assisted living and home monitoring systems are gradually becoming a necessity, considering the current trends in population ageing and older adults' desire to continue living independently in their homes and their communities for as long as possible. This paper presents our current achievements regarding the implementation of a cyber-physical system for assisted living and home monitoring, developed...
