Indoor service robots need perception that is robust, more privacy-friendly than RGB video, and feasible on embedded hardware. We present a camera-free 2D LiDAR object detection pipeline that encodes short-term temporal context by stacking three consecutive scans as RGB channels, yielding a compact YOLOv8n …

Waterschap Scheldestromen has a measurement device named Multiflexmeter. It uses the LoRaWAN technology to send the measurement data to the gateway. But sometimes, the Multiflexmeter can not connect to the gateway to send data because the line of sight is blocked. So the company is seeking a design of …

Water Authority Zuiderzeeland measures many parameters for the WFD objectives, including electrical conductivity (EC). The EC is measured using various measuring devices, through field measurements (manual), telemetry and since 2019 with relatively inexpensive Internet of Things (IoT)sensors. It is not …

This paper extends the 'go-with-the-flow' method to explore enclosed environments, like oil reservoirs, pipe lines that transport liquids, and industrial tanks for processing chemicals, where sensing nodes cannot establish communication with the external world. Nonetheless, large quantities of highly …

Dit werk is gericht op 3-D lokalisatie van sensormotes in massale zwermen, uitsluitend gebaseerd op 1-D relatieve afstandsmetingen tussen naburige motes. We richten ons op toepassingen in afgelegen en moeilijk toegankelijke omgevingen zoals de exploratie en het in kaart brengen van de binnenkant van …

In order to determine whether small-sided game (SSG) locomotor performance can serve as a fitness indicator, we (1) compared 6-a-side (6v6) SSG-intensity of players varying in fitness and skill, (2) examined the relationship of the 6v6-SSG and Yo-Yo IR2 and (3) assessed the reliability of the 6v6-SSG. …

BACKGROUND: Exercise capacity, muscle function, and physical activity levels remain reduced in recipients of lung transplantation. Factors associated with this deficiency in functional exercise capacity have not been studied longitudinally. OBJECTIVE: The study aims were to analyze the longitudinal change …

The purpose of this report is to assess the relevance of the measurement of the spectrally resolved distribution of radiation in tokamak boundary plasmas. This assessment is important and urgent in view of the recent ambition to design and construct a multi-camera configuration for hyper imaging spectroscopy1 …

This project helps to reach the end goal of doing long distance measurements. Long distance measurements depends on the refractive index of air. The refractive index depends on temperature, pressure, humidity and gas mixture. The biggest uncertainty of calculating the refractive index is the temperature, …

A new gravitation wave observatory is being built in Japan. This facility is a big Michelson interferometer where the mirrors and sensors will be made cryogenic down to 4 K. The problem is that: the heat cannot be transported out of the mirror by its surroundings because the whole system is in an ultra-high …
