The use of blockchain technologies and Smart contracts to improve the quality of Microgrid network management is considered. The necessity of using a special mathematical apparatus for system analysis is noted, taking into account the nonlinear nature of dynamic processes in the network and, in particular, the presence of sharply changes in the load. The advantages and disadvantages of the approach known in the literature are analyzed, when the search for the optimal power distribution among generators to ensure the minimum costs of the Microgrid is carried out on the basis of nonlinear programming methods. Graphs of transient processes in the network are given and their corresponding analysis is carried out. © 2023 IEEE.

For the simulation of the propagation of electromagnetic waves is in certain situations the parabolic approximation of the scalar wave equation commonly used. It is important to have well-performing transparent boundary conditions applied on the boundaries of the finite computational window, to enable the superfluous portion of the propagating wave to radiate away from the e.g. wave guiding structure. Four different formulations (continuous, two kinds of semi-discrete and one fully-discrete) of the non-local transparent boundary conditions are described and their performance compared. © 15th International Symposium on Theoretical Electrical engineering, ISTET 2009.

In recent decade, the research in nanotechnology brought the idea of nanofluids which are highly conducting materials. Some important applications of nanofluids are justified in pharmaceutical industry, coolants in vehicles engine, preparation process of various medicines for treatment of fatal diseases like cancer, aircraft industry, latest heat exchangers etc. The ferro particles are special class of nanomaterial which attract variety of interest from the researchers. The objective of current research is to perform the investigation for heat and mass transfer subject to Carreau nanofluid to observe the enhancement of heat transmission phenomena. The induction of magnetic dipole has been observed for thermal transport phenomenon. The flow is causing by stretched surface. A simplified system is obtained by utilizing the dimensionless variables. Physical interpretation of results have been presented. Result showed that temperature profile in presence of ferrofluid fluid boosts up with escalation in thermophoresis parameter, while opposite behavior is noted for power law index. The concentration of ferrofluid showing declining behavior for Schmidt numbers and rises for thermophoresis parameter. © 2024

In this article, we are introducing the method of the localization of the deep-ocean pipe end-point. The set of various sensors located along the pipe are used for measuring the data describing the shape of the pipe. Several variants of calculation algorithm have been developed for the processing the gathered information. The simulation results describing the error characteristics of the input and output variables are included as well. The article contains also the basic information about the technical realization concept of the proposed method. Copyright © 2013 by The International Society of Offshore and Polar Engineers (ISOPE).

The real-time implementation of control and estimation algorithms on microcontrollers with limited memory and computational power requires a model that describes the dynamics of the vibrating system in sufficient detail, yet makes real-time deployment on sampled systems feasible. While extracting a model from finite element analysis is always possible, this approach yields models that are too complex to be evaluated in sample timing that is typical for vibration phenomena. In case of nonlinear vibrations, this is even more critical as state-of-the-art optimal control and estimation algorithms will have to evaluate a non-convex objective function. This paper introduces the modeling and system identification procedure of a nonlinear vibrating beam that results a real-time feasible mathematical model. Position and velocity measurements are made on a slender vibrating beam mounted equipped with a tip mass on a linear excitation stage using non-contact laser Doppler vibrometry. The measurement results are then fitted to two model candidates by using genetic algorithms to identify unknown parameters. Models are verified in simulation and their outputs are compared to experimental measurements. © 25th International Congress on Sound and Vibration 2018, ICSV 2018: Hiroshima Calling.

Enhancement of Adaptive Software-Based Self Test Generation of Embedded Processors Cores

The paper deals with automatic software-based test generation for processors as basic blocks of current complex systems on chip and embedded systems. Testing processors needs continually new test generation methods, algorithms and test application techniques for their verification, manufacture and infield testing and reliable life-time run. The functional tests of processors are mainly generated over an instruction set architecture and processor model description. Such types of tests are serving as additional tests to structural testing or as tests used in verification. They run in similar form and frequency as real programmes. Such tests are categorized as the software-based self tests. A metric for quality evaluation of the software-based tests is obviously provided by code coverage of a processor model. A functional test generation method is based on VHDL model of processors and genetic algorithms with using various evolutionary strategies. The contribution to the SBST methods based on GAs using the latest defined ES was identified. Functionality and effectiveness of the developed methods were evaluated in the implemented system AGenMIX with enhanced function of genetic algorithms computation over three types of RISC processor.

5th IFAC Symposium on Mechatronic Systems, MECHATRONICS 2010

The estimation of parameters and states is one of the core data-processing algorithms used for the monitoring and control of continuum or structured mechatronical systems (e.g., flexible robotic arms and cantilevers). The measurements taken from the sensors combined with an appropriate model can filter the states and extract information about vibration dynamics parameters such as damping and spring constants. This paper presents a method based on the application of a Moving Horizon Observer (MHO) for state and parameter estimation of a lightly-damped vibrating system. A numerical experiment on a single-degree-of-freedom (SDOF) system is performed to demonstrate the method on noisy measurements and to compare the MHO with the benchmark Extended Kalman Filter (EKF). Test scenarios show that the MHO appears to be more robust with respect to modeling errors. © 2010 IFAC.

In this paper we examine the first working implementation of a fully homomorphic scheme from *** and ***. We implemented the ciphertext-only attack from [2] using the NTL library and show that only dimensions up to 128 are feasible for common computational power. We propose also two improvements of this attack that enable us to use the fastest variant of LLL from NTL and compare the results. © 2013 Springer-Verlag.

Fulfilling increasing performance demands of space and automotive applications can be problematic as high dependability is required. Memory is one of the most radiationsensitive parts, so it is often protected with information redundancy. This paper describes an integration of error correction and detection techniques into the interface of RISC-V processor to protect the data stored in the memory. We also provide a hardware-software interface for reporting errors and software routines for correcting data in memory. Our solution has a negligible impact (-3.9%) on the overall performance of the core with a small area and power consumption overhead.
