The paper presents an analysis of different iterative solvers used for computing large and very large linear and nonlinear matrix systems. The solvers compared were used to solve the Finite Element Method (MEF) 3D models of a steady magnetic field distribution in a hybrid bi-phase stepper motor. The modeling was done using the professional software COMSOL Multiphysics. The convergence, the computational time, and the preconditioning method influence on the iterative solvers were analyzed using four different discretization meshes. Both the linear and the non-linear models (due to constitutive magnetic nonlinearity) were studied.

The paper presents the design of a (Shape Memory Alloys) SMA-in-the-loop testing stand, which allows the testing of the controllers of any type of software implemented by Simulink platform in real conditions. The stand offers the possibility to test SMA and SMA-based actuators by electric current driving for the heating stage and air forcing the cooling process. Also, it allows the acquiring of the parameters: voltage and intensity of the driving current, SMA temperature, accomplished displacement and force. The stand was tested under the following hardware structure: software implemented controllers running on PC, Arduino Due as interface with the physical environment, Arduino Uno-based dual output buck converter and sensors. The stand can be easily extended by other components, it is very flexible as structure.

There are situations in practice when it is necessary to estimate the rotation speed of the heat engine of a car when its tachometer is not in a good health. In this case, a quick method of speed estimation, noninvasive if possible, even if it may not be very accurate, may be of help. The present paper proposes such a method for estimating the rotation speed of an internal combustion engine, utilizing the signals produced by the engine vibrations acquired with a mobile phone and supervised machine learning (ML) algorithms. The paper describes the complete process of the method, with details regarding the data acquisition and preprocessing, features building and ML algorithms implementation. An example of field deployment is also provided and an analysis is made about how a series of parameters influences the method and may be optimized in terms of two important criteria: accuracy and computation effort. Finally, a trade-off between the two criteria is carried out, specifying the optimal conditions for deploying the method in the field.

Battery storage systems are widely used in several applications; in particular, they are fundamental in electrical or hybrid electrical vehicles. The different storages are interfaced to the inverter with a DC-DC converter in order to match the different voltage levels. The battery systems are subjected to aging phenomenon and if one battery is deteriorated, all the series is involved. To avoid this problem, a double-input DC-DC converter is proposed in this paper. The two storages can be controlled independently and, therefore, the system reliability is improved. Moreover, the deteriorated battery is not bypassed, therefore it can provide energy to the system at a limited rate and so the system performance is maximized. In addition, batteries based on different technologies can be mixed by the proposed converter obtaining the best from each technology.

The analysis of the behavior of non-linear elements in electrical equipment is particularly important, especially in the non-sinusoidal regime. In this case, the non-linearity of the circuit elements generates additional current and voltage harmonics that worsen the energy quality and become dangerous for the normal operation of electrical equipment. There are specialized classical software tools for the analysis of these circuits that do not provide all the necessary information about the new harmonic content of the circuit and about the contributions of non-sinusoidal regime and non-linearity. This deficiency is solved by the method proposed by the authors. The method uses a mathematical model based on the multinomial theorem and the nonlinear characteristic i(u) of the circuit element. An original symbolic algorithm determines both the new content of the current harmonics for different operating regimes as well as the contributions of the voltage harmonics and the coefficients of the approximation polynomial i(u) to the current harmonics. The results obtained on two studied cases are compared with traditional simulation techniques and validated by their accuracy.

A twin core photonic crystal fiber-based surface plasmon resonance sensor has been designed in this work to detect a wide range of refractive indices with high sensitivity. The dual core fiber is polished on both sides and the metal layer is deposited on the polished surfaces as the plasmonic materials. Two microchannels are employed on each side of the fiber and thus the sensor forms four separate plasmonic layers on the external surface of the fiber to achieve a wide detection range. Plasmonic material silver is used here due to its availability and low cost. A thin layer of (TiO2) is used on top to prevent oxidation of silver. The proposed design is easy to fabricate and exhibits a good fabrication tolerance. The sensing application is also convenient as the analyte is placed outside the fiber. The analyte refractive index detection range of this sensor is found 1.23 – 1.44. The maximum spectral sensitivity of the sensor is 28200 nm/RIU and the corresponding resolution is 3.55 × 10−6 RIU. The maximum amplitude sensitivity of the sensor is 286 RIU−1. Due to its high sensitivity and wide detection range this sensor can be used to detect various low refractive index (1.23 – 1.29) chemicals (like halogenated anesthetic agents, refrigerants, different type of aerogels) to various bio materials (biological tissues, cancerous cells, hemoglobin) which has refractive indices usually in the range of 1.3 – 1.39, to various high index (1.4 – 1.44) analytes (like high concentration of electrolytes, proteins).

Knowing the dielectric parameters of human tissue is a matter of fundamental importance for a correct medical diagnosis, considering that these values differ from a healthy tissue/organ to an affected one.The mathematical apparatus that ensures the operation of these working models is accompanied by a set of necessary conditions (assumptions about mathematical spaces and operators, their conditions of existence, initial conditions, etc.), which should not be violated. In this paper, we will analyze the circumstances in which the theoretical conditions could be violated and the consequences of their violation concerning recording the electrical properties of human tissue, and particularly the effects of the layers of tissues that cover the human brain, in the process of calculating their dielectric parameters. This is still an open issue with major implications for medical diagnosis. We analyze the local and global hypothesis of tissue isotropy, the errors that occur when these hypotheses are ignored and how these errors affect the medical diagnosis. We also make a flash on the results and the most inspired solutions found in the field; finally, we discuss our answer to this problem.

The sizing of earth grounding (EGR) is approached in the perspective of applying optimal criteria such as minimum footprint, conductive material consumption or investment costs. The soil resistivity, as a defining quantity for the dispersion resistance of the EGR, is analyzed to decide on the range of variation of its values and to estimate the maximum value, to be adopted in the design. The calculation relations are grouped in the sequence of their use, thus composing the complete physical model of the studied application. The known limited indications of the HEG utilization coefficient are compensated by proposing a linear relation for the calculation of this quantity as a function of the electrode length and the in-plane distance between neighboring parallel electrodes. Due to the non-linear physical model of HEG, it was necessary to develop an algorithm for the successive identification of the computational sizes, which is the basis for the determination of the triad electrode length-electrode number-distance between electrodes. The values of the dispersion resistance of the interconnecting conductor between the electrodes being important for the determination of the total dispersion resistance of the HEG, its calculation was included in the physical model of the EGR. Using the complete physical model of the HEG, a series of sizing runs are made to highlight the possibilities of applying the optimality criteria in setting the final values for the HEG specific quantities, under the mandatory condition of bringing the dispersion resistance of the EGR within the allowed range. Two of the optimal criteria represented by the minimum footprint area or mass of metallic materials were tested on a series of concrete data in order to determine areas of interest for future studies.

In this paper the gm/ID methodology for designing analog CMOS circuits is used. As a case of study the single-ended Miller OTA design is widely discussed and analized. In order to show the advantage of gm/ID it is demonstrated that the first order building block approximation allows to understand not only how to correctly do the sizing of each transistor, but also the physical meaning of each small-signal design model. This design flow is carried out by using design rules of a 130 nm CMOS technology, where Cadence is used for performing simulations at transistor level, obtaining results that confirm the usefullnes of the design models and the basics’ veracity.
