This study proposes a simple classification method for drivers based on their driving confidence and authority using feedback from steering wheel angle and traction motor current measurement data. Data is collected from 38 drivers on a prototype electric vehicle. For the classification process, the driving performance of each driver is assessed with respect to an expert driver. The data is time-stamped and geo-referenced. The experimental driving data is comprised of the two command inputs that the driver generates to regulate handling and lane-level tracking. Deviations from the expert's performance data are considered to be a measure of potential failure of the driver's confidence and authority leading to a possible accident. The dataset of the participating drivers is processed by extracting the mean, standard deviation, skewness and kurtosis values. Extracted features are evaluated with different classification methods, including KNN.

The estimation of unobservable states of a process is important when using control techniques that assume, said a priori, known values. The controllers based on the state space present good behavior and efficiency, even when the dynamics of the process are non-linear. One of the processes with non-linear dynamics and in which not all the states are observable is the case of parabolic trough solar plants. In this work an observer is presented, based on a fuzzy inference system, for the estimation of the temperature profiles of the loops that make up the solar field. This is a English translation of an earlier work presented in the XXXIX Spanish workshop in automatic control [15]. © 2019 IEEE.

The direct calculation of the absorption coefficient spectra of various tissues from spectral measurements allowed to retrieve the contents of melanin and lipofuscin. In the rabbit brain cortex, 1.8 times higher melanin content is explained by the neuron degeneration process. Similar melanin and lipofuscin contents were found in the rabbit pancreas as a result of the tissue aging process. The conversion of 83 % of the melanin in the human normal kidney into lipofuscin in the cancer kidney indicates that lipofuscin can be considered a kidney cancer marker in humans. © 2022 IEEE.

In this study, MMSE-K and a PTP reaching task in a VR space were conducted on groups of university students and senior citizens to find out the relationship between cognitive and motor performance indices. During controller-visible task, while seniors with relatively high MMSE-K scores (above 24) have shown no statistical difference with university students in terms of final position errors, seniors with low survey scores have shown significantly greater errors. Therefore, we observed cognitive functions are closely related with motor functions and spatial perception, so we expect that VR PTP reaching task would help early predictions on mild cognitive impairment. © 2019 IEEE.

The purpose of the following proposal is to create a new class of antennas of low weight but with a large transmitting and receiving surface made of metallized fabric. This class of antennas will be stationed in low satellite orbits, at about 2000 km from sea level and will be easily steerable by exploiting the interaction between the earth's magnetic field and an electromagnetic field generated on the antenna. The possibility of orienting very large ultra-light balloon-like MW antennas, orbiting in the Earth magnetic field, through electric currents flowing in conductive wires embedded in the antennas walls, are examined. It is shown that such currents may easily provide the needed forces without the necessity of mechanically orienting the antenna itself. The antenna is extremely light, inexpensive, easily directional. The antenna has the shape of a spheroid in which the southern hemisphere has a parabolic shape made of metallized fabric;the northern hemisphere, transparent to the electromagnetic radiation, has a radius of curvature such that the north pole coincides with the focus of the parabola. © 2023, CC BY-NC-ND.

The Electrical engineering undergraduate program of the Escola Politécnica of the Universidade de São Paulo has created an alternative innovative curriculum path for its freshmen students in 2024. The Competency-based Path emphasizes the development of competencies and skills for the unprecedented technological advancements that necessitate a holistic education for future electrical engineers, preparing them with practical skills for real-world challenges. The program was designed using an innovative methodology and centers around semester-long or year-long integrative projects. These projects bridge the gap between theory and practice, as students deal with real-world challenges while fostering social responsibility.

A novel nonlinear controller that inherently limits the RMS value of a three-phase grid-following inverter current is presented in this paper. Using the dynamic model of the inverter in the rotating dq reference frame, a nonlinear control scheme is formulated to ensure accurate real and reactive power regulation with RMS current limitation that avoids the use of saturation units with upper/lower limit adaptation, as commonly used in the existing approaches. In particular, it is analytically proven by using fundamental nonlinear systems theory, that the RMS value of the inverter current will never violate a given maximum value, both during the transient response and at the steady-state. Moreover, a detailed root locus analysis is provided to guarantee the asymptotic stability of the desired equilibrium point for the closed-loop system. Finally, to validate the proposed controller performance, simulation results of a grid-following three-phase inverter equipped with the proposed control approach are presented under both normal and unrealistic values of the real and reactive power setpoints.

The paper proposes a mathematical model of a three-phase induction motor with an asymmetrical twelve-zone winding of stator with parallel connection of subwindings. The mathematical model was developed using the theory of generalized electromechanical converter and contains equations of electrical equilibrium of six stator windings and three rotor windings. The equations for calculating the electromagnetic moment and the equations of motion of the induction motor with an asymmetrical twelve-zone stator winding rotor were obtained. The developed mathematical model in the form of cell-matrix equations has been implemented in MATLAB/Simulink.

KPIs for Manufacturing Operations Management: driving the ISO22400 standard towards practical applicability

IFAC-PapersOnLine 2018年第11期51卷 7-12页

A set of key performance indicators (KPIs) for manufacturing operation management is introduced in the ISO 22400 standard. However, KPIs are only defined at a high abstraction level and this hampers the standard's practical adoption. In this paper, a framework is introduced in order to solve this weakness. Starting from the analysis of the relevant measurements used in the KPIs’ formulas, a classification model is introduced defining three possible application scopes - work orders, work units and production orders - to analyze each basic element of the standard. As a result, the KPIs defined in the ISO 22400 standard are more precisely specified and, as a consequence, also suitable to be straightforwardly implemented in performance measurement systems. © 2018

Bayesian neural networks are powerful inference methods by accounting for randomness in the data and the network model. Uncertainty quantification at the output of neural networks is critical, especially for applications such as autonomous driving and hazardous weather forecasting. However, approaches for theoretical analysis of Bayesian neural networks remain limited. This paper makes a step forward towards mathematical quantification of uncertainty in neural network models and proposes a cubature-rule-based computationally-efficient uncertainty quantification approach that captures layer-wise uncertainties of Bayesian neural networks. The proposed approach approximates the first two moments of the posterior distribution of the parameters by propagating cubature points across the network nonlinearities. Simulation results show that the proposed approach can achieve more diverse layer-wise uncertainty quantification results of neural networks with a fast convergence rate.
