A low-cost sensornode is introduced to monitor the 5G EMF exposure in the Netherlands for the four FR1 frequency bands. The sensornode is validated with in-lab measurements both with CW signals as for QAM signals and perform for both cases and for all frequency bands an error less than 1 dB for a dynamic …

Permacomputing is a nascent concept and a community of practice centred around design principles that embrace limits and constraints as a positive thing in computational culture, and on creativity with scarce computational resources. As a result, permacomputing aims to provide a countervoice to digital …

In this work, a feasible and low-cost approach is proposed for level measurement in multiphase systems inside tanks used for petroleum-derived oil production. The developed level sensor system consisted of light-emitting diodes (LEDs), light-dependent resistor (LDR), and a low-cost microprocessor. Two …

Machine learning models have been an inevitable tool for analyzing medical images by radiologists. These models provide important information about the contents of these images using extracted radiomic features. However, the dimensionality of the feature space can cause reduction in the accuracy of prediction, …

This report presents 1) a biodiversity baseline study conducted in the restored areas of the Mushullakta community, Napo, Ecuador, and 2) a community-based monitoring protocol for ongoing biodiversity monitoring. Monitoring is a vital part of conservation and restoration, as it provides practitioners …

Many ARM Cortex-M-based microcontrollers include tracing features which allow monitoring hardware events (e.g. exceptions occurring, a specific instruction being executed or a specific address range being accessed by the CPU). Tracing enables non-intrusive insight into software execution (i.e. software …

OOS International is a Netherlands-based international offshore service provider for accommodation, ship management and heavy lifting. OOS provides highly qualified construction services within the oil and gas industry. The OOS Tiradentes is a Semi-Submersible Accommodation Vessel (SSAV), which can accommodate …

In this study, aviation, energy, exergy, environmental, exergoeconomic, and exergoenvironmental analyses are performed on a CFM56-3 series high by-pass turbofan engine fueled with Jet-A1 fuel. Specific fuel consumption and specific thrust of the engine are found to be 0.01098 kg/kN.s and 0.3178 kN/kg/s, …

In dit rapport worden de maatschappelijke kosten en baten onderzocht van waterstof-elektrisch rijden voor vrachtverkeer. De keten van elektriciteitproductie, conversie naar waterstof, opslag en transport van waterstof, waterstoftankstation en waterstofvrachtwagen is gemodelleerd. De total cost of ownerschip …

Community energy can be conceptualized as a social movement, which aims to develop a sustainable, democratic, and localist energy system. Increasingly, community energy initiatives aim to develop citizen-led heating projects. District heating projects are characterized by costly investments, a substantial …
