This paper presents an educational system for practical laboratory experiments accompanying an introductory course in power electronics. The lab setup is comprised of a printed circuit board with a half-bridge topology which can be used either as buck or as boost converter and a low cost microcontroller evaluation kit. Control of the DC/DC converter is based on a programmable system on a chip (PSoC)...
Mass repartition onboard lightweight aircraft is a crucial problem as it may generate difficulties for the pilot during the landing phase. Being able for the pilot to land the plane properly is of course an important aspect for safety, but also for structure integrity. So the mass repartition monitoring could avoid hard landing occurrences. Hence, it is interesting to develop a mechatronic system...
Today, performing life tests on power semiconductor devices is of major importance in industrial and automotive power applications. Traditionally, qualification tests, like the HTOL test, are carried out in a semi-automated manner. This paper first reviews different test methods and a recently proposed modular test system (MTS) that allows testing of individual devices as well as application specific...
Autonomous vehicles are equipped with a variety of instrumentations, sensors and controls depending upon the mission of the target vehicle. One of the biggest challenges in developing autonomous vehicles system is their cost. Often times, researchers with limited budget do not have the resources to acquire realistic autonomous vehicle test platforms for carrying out their experiments on. Most researchers...
This paper presents research results of the novel system to control traffic lights which is based on the common European model. One of the most important measures for dealing with this problem is to adopt favorable traffic signal control strategy. The main objective of this research is to develop an effective procedure to control the traffic, which tries to reduce possibility of traffic jams. Additionally,...
This paper presents a timing error masking-aware ARM Cortex M0 microcontroller system. Timing errors are detected through a timing error detection strategy, consisting of a soft edge flip-flop combined with a transition detector and an error latch. The time borrowing realized through soft edge flip-flops allows data to propagate after the clock edge (timing error masking). Thus operation at the point-of-first-failure...
A photonic bio-recognition system has the potential to be used with the advancement in a biosensor development. The system requires an optical sensing system, microfluidic device and biological reagent for microorganism detection. Although, biosensors are available in the market, a label free and a lab-on-chip approach will be a flexible solution. The main objective of this work is to develop photonic...
Nowadays, parents are perturbed about school going children because of the increasing number of cases of missing students. On occasion, students need to wait a much longer time for arrival of their school bus. There exist some communication technologies that are used to ensure the safety of students. But these are incapable of providing efficient services to parents. This paper presents the development...
One of the growth factors of corn plant is fertilizer according to nitrogen fertilizer requirement. The identification of nitrogen fertilizer requirement in corn plant can be done by measuring the green leaf level using Color Leaf Manual, using TCS3200 color sensor combined with Arduino Uno Board microcontroller, and information. In this study a tool was created that could automatically measure the...
In India, the most crucial threat that adds up is the striking amount of waste generated every day by a human being. Around 62 million tonnes of waste is produced each day by 377 million people living in urban India of which 45 million of waste is left untreated and disposed unhygienically causing severe health issues and environmental degradation. Ultimate destination of solid waste in India is at...
A demonstrator has been developed to illustrate the performance of a lightweight fingerprint recognition algorithm based on the feature QFingerMap16, which is extracted from a window of the directional image centered at the convex core of the fingerprint. The algorithm has been implemented into a low-power ARM Cortex-M3 microcontroller included in a Texas Instruments LaunchPad CC2650 evaluation kit...
Falling sphere viscometer is one of the most commonly used techniques in experimentally determining fluid viscosity. This method requires the measurement of the terminal velocity of a falling sphere inside the fluid, which remains a challenging and costly task, especially if high precision is required. This paper presents the development of a low-cost visionbased falling sphere viscometer. The velocity...
