A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

1. System Principle
Rated Lumen Maintenance Life, the elapsed operating time over which the LED light
source will maintain the percentage, p, of its initial light output e.g:
L70 (hours): Time to 70% lumen maintenance
L50 (hours): Time to 50% lumen maintenance
The LED life is predicted according to the Arrhenius model, the formula as following:
1. P=P0 exp(-βt)
2. β=β0 IFexp(-Ea/KTj)
Note: P0 is initial lumen; P is lumen under heat and electricity; β is recession
coefficient in a certain temperature; t is the time to electricity in a certain
temperature; β0 is constant value; Ea is activation energy; K is Boltzmann's
constant; IF is working current; Tj is junction temperature.
Firstly, we predict the LED life per 10000hours. For example, we suppose the
optical decay rate is n% in 1000hours, then:
Base on formula 1, L50 is: t=1000*ln0.5/ln(1-n%)
Base on formula 1, L30 is: t=1000*ln0.7/ln(1-n%)
So we can get:
Item Optical decay rate L50(h) L30(h)
85℃ 8% 8312.950414 4277.62127
70℃ 3% 22756.57306 11709.922
The temperature Tj (the contact surface temperature between LED and circuit board,
or ambient temperature providing the heat-sink is complete, but the junction
temperature will be 15 higher than ambient temperature in 350mA) will greatly℃
affect the test result. We can predict the LED life under varies temperature
according to formula 2. Suppose the time t1 is the LED life under T1 temperature,
time t2 is the LED life under T2 temperature, then we can calculate the time t3 under
T3 temperature: t3=t1*exp{(ln(t2/t1)/[1/(T2+15+273)-1/(T1+15+273)] *
[1/(T3+15+273)-1/(T1+15+273)]}

2. System Configuration
Refer to LM-80, the LED typically exhibit very long operational life characteristics
and, depending on drive current and use conditions, can be in use for 50,000 hours
or longer.
The LED Lumen Maintenance and Life Test System include two parts of function: LED
lumen maintenance life and also measure the LED colorimetric parameters
maintenance curve such as CCT, Chromaticity and spectrum.
PS. The customer needs to prepare the PC and Printer
The full system of LEDLM-80PL includes the following items:
LED Aging Control System with Arrhenius Software (LM-80PL): it
measure total 16 channels on the following curve: photometric VS colorimetric

VS power VS temperature VS time. The aging time can be max 10K hours. It can
calculate the life according to TM-21.
Multiplex Temperature Tester (TMP-16): To measure temperature for 16
channels samples, it can communicate with PC via LM-80PL software
Photometric & Colorimetric & Electric Parameters Measurement
System: To measure photometric, colorimetric and electric parameters for 16
channels, all the instruments can communicate with PC via LM-80PL software
Multi-Channel Power Switch System: to control the power for the test lamp
Lamp adapter in High and Low Temperature Chamber: design according
to customer’s request, max 16pcs.
Please note the following two items needs to prepare separately:
High Temperature Chamber: depend on the test lamp size
AC Power Source: depend on the test lamp power
