This paper investigates distributed control of a heterogeneous MAS with unknown disturbances, actuator saturations and sensor faults connected through a directed graph. The RBFNNs have been employed to estimate the uncertain nonlinear functions and design the nonlinear disturbance observer. The distributed controller is designed to stir the followers to follower the leader with very small tracking errors. The stability of the closed loop system has been guaranteed with the aid of a Lyapunov function. Finally, a simulation example has been provided to illustrate the effectiveness of the presented method.

In recent years, Bulk heterojunction organic solar cells (BHJ OSCs) based small molecules take leading position of industrialization for their considerable opto-electronic properties and uncomplicated fabrication process. Materials based on cyclopentadithiophene (CPDT) have been widely used thanks to their interesting structural and electronic characteristics. Here we report a combined experimental and theoretical investigation of a CPDT-based material namely 6,6′-(2,5-bis (hexyloxy)-1,4-phenylene) bis(2-methyl −4H- cyclopenta [2,1-b:3,4-b'] dithiophen-4-one) (CPDT-alt-BHP) as donor small molecule in a BHJ OSC. The synthesized molecule shows a rigid and planar structure with small band gap energy. The electronic properties have been investigated by means of Density Functional Theory (DFT) at B3LYP/6-31g(d) level of theory. The studied molecule displayed an optical absorption in the visible region with $lambda_text{max}=404$ nm. Transition density matrix (TDM) plot was carried out to get insight into the hole-electron coherences at the first excited state. The photovoltaic parameters of CPDTBHP:[70]PCBM system were simulated using wxAMPS software. The designed BHJ OSC exhibited respectable fill factor (FF) of 81.13%, short-circuit current density (Jsc) of 6.089 mA cm-2 and power conversion efficiency (PCE) of 4.922%. The studied compound offers significant structural and optoelectronic properties that could be enhanced via judicious molecular tuning.

With the development of greenhouse technologies using saltwater for evaporation and cooling, irrigation of arid regions may be possible with proper power sources. We present here space-based solar power (SBSP) as a way of expanding the irrigation network and demonstrating the relevant technologies. Once implemented, SBSP could be used for other terrestrial applications as well as space missions on the Moon or Mars.

Alzheimer's disease (AD) detection corresponds one of the most powerful and challenging tasks in medical imaging processing. This paper describes the survey of recent AD detection techniques in the last ten years. The process of AD detection can include different stages such as preprocessing, feature extraction, feature selection, dimensionality reduction, segmentation and classification. In this survey, we review the recent findings and future trends and we set out the various types of AD detection techniques with their major contributions. The performances of the most important AD detection techniques are compared and discussed according to the applied algorithms, approaches and databases (e.g. OASIS, ADNI and MIRIAD).

This paper presents a new advanced sliding mode control (SMC) based on backstepping approach for an open-end stator windings dual-stator induction motor (DSIM-OESW) under low speed condition. The proposed motor topology is fed by four three-phase voltage inverters with two isolated DC sources, and is controlled using Pulse Width Modulation (PWM). The proposed control technique includes the identification of motor parameters. A simplified Extended Kalman Filter (EKF) estimator is proposed for the estimation of both rotor flux and rotor speed. The sensorless control scheme is built within the Simulink environment combined with hardware-in-the-loop platform. The obtained results illustrate the correctness of the proposed sensorless control approach under different operating conditions, especially at low speed operation.

The next milestone in the automotive industry is to achieve the complete autonomous driving capability. This demands high performance computing controllers and a larger number of Electronic Controller Units (ECUs) for realizing this goal. Also, the current shift towards electric cars where the battery capacity is limited, urges for new efficient approaches. Therefore, developing compact, miniaturized integrated controller that encompasses all the features is essential for minimizing the power consumption. At the same time, this approach of ECUs must also ensure the cost efficiency. To address and handle this need, the reduction in the ECUs numbers is necessary to reduce the cost factor but at the same time not compromising on the functionalities. Therefore, the approach of integrating these individual features in a single ECU is a promising way forward, i.e., System-on-Chip (SoC). To design and implement such an SoC for the automotive industry that ensures the safe operation of the controlled functions, it must follow a particular development criterion according to the ISO 26262 - functional safety of the road vehicles. This work focuses on the development of an SoC according to the ISO 26262 standard based on ARM Cortex M3 architecture which is an attractive candidate due to its low cost and low power consumption.

Cable identification has a significant role in cable maintenance and fault detection. Before replacing defective cables in a network, they must be properly identified. In this paper, a novel method for coaxial communication cables identification based on scattering parameters is proposed. The input port reflection's magnitude measured by a Nano Vector Network Analyzer at 101 frequencies for 10 coaxial communication cables are used as features for the K-Nearest Neighbors algorithm. The investigation is held on cables of various lengths, dimensions and connector types. The cable's length, type and connectors are considered as a unique class. The classification accuracy reached is 99% for a test set composed of 100 measurements.

Knowing that electric insulating liquid is a weak link in a composite or impregnated dielectric system, many investigators have devoted great efforts to enhance our basic knowledge of the behaviour or aging characteristics of insulating oil under different stresses. Understanding the process of insulating oil degradation is of utmost importance for both manufacturers of electrical equipment and maintenance planners. The process of degradation may alter the physical and chemical structure of the insulating liquid and may lead to the creation of new products or to an increase and decrease in the concentration of existing functional groups. Optical techniques such as ultraviolet-visible spectroscopy and Fourier transform infrared spectroscopy are powerful non-destructive techniques to assess the degree of degradation and the shift in atomic or molecular concentration and structure. An in-depth lecture of the optical spectroscopy responses may be used to enhance diagnostic techniques such as DGA method. The aim of this contribution is to use different spectroscopy measurements for studying the influence of low electrical discharge and the local overheating fault on transformer oil properties and investigate the correlation between the different methods. In this regard, various scenarios were considered; the study was carried on mineral oil and the gassing behaviour, as well as turbidity (ASTM D6181), dissolved decay products (ASTM D6802) and infrared spectres have been monitored. The results show that mineral oil is highly susceptible to local overheating and generates further decay products, and the correlation of FTIR spectral responses with DDP and turbidity measurements provides initial knowledge that transformer states can be recognized by using spectroscopic techniques as a non-destructive diagnostic technique

This paper presents a fully autonomous measurement system based on thermoelectric generators (TEGs). The system implements a battery-less device that, by using a TEG, harvests energy from a thermal gradient and it is able to perform measurements with the same transducer. The device implements a conditioning circuit to harvest energy using an ultra-low-power system on chip (SoC) provided by STMicroelectronics. The SoC plays the role of sensing the harvested energy to activate a Bluetooth Low Energy radio as soon as the harvested energy is enough for transmission. The measuring method exploits the proportionality between the thermal gradient and the frequency of the transmitted beacons. The reading of the measurement data uses a convenient time-domain readout approach. Results and experiments evince the suitability of the proposed solution with the possibility to adopt and disseminate the device in various environments and for application in an industrial scenario.
