Single-Pixel Thermopile Infrared Sensing for People Counting

People-counting data can be used in building-control systems to improve comfort and in space management applications to optimize building space. In this work, we consider a combi-sensor with a single-pixel thermopile and passive infrared sensor for people counting. We first develop a thermopile signal model for object temperature measurements...

The impact of natural fractures on heat extraction from tight Triassic sandstones in the West Netherlands Basin: A case study combining well, seismic and numerical data

The positive impact that natural fractures can have on geothermal heat production from low-permeability reservoirs has become increasingly recognised and proven by subsurface case studies. In this study, we assess the potential impact of natural fractures on heat extraction from the tight Lower Buntsandstein Subgroup targeted by the recently...

Low-temperature thermochronology as a control on vertical movements for semi-quantitative source-to-sink analysis: A case study for the Permian to Neogene of Morocco and surroundings

Continental passive margins and their hinterlands in the Atlantic realm have been the locus of many Low Temperature Thermochronology (LTT) and time-Temperature (t-T) modelling studies that evidence pre-, syn- and post-rift episodic km-scale exhumation and burial episodes. In this study, we integrate data from over 30 published LTT and t-T...

Temperature variation effects on electrostrictive actuators and its quasi-static compensation

Deformable mirrors are used for changing the wavefront of the reflected light by using one or more actuators behind the mirror to physically deform it. This application is widely used in telescopes to compensate for atmospheric aberrations using a feedback wavefront sensor. Recent advances in lithography process require more precise wavefront...

Phanerozoic Vertical Movements in Morocco

Our understanding of the Earth’s interior is limited by the access we have of its  deep layers, while the knowledge we have of Earth’s evolution is restricted to harvested information from the present state of our planet. We therefore use  proxies, physical and numerical models, and observations made on and from the...

Energy Yield Model for Bifacial PV Systems: A study and analysis of temperature & rear irradiance models

In order to make the bifacial yield prediction models commercially available, a lot of work their development, improvement and validation is being done by many research institutes. At Energy research center of the Netherlands (ECN), one such model is under development. In this project, couple of aspects were investigated to give better insight...

Development and performance of a parsimonious model to estimate temperature in sewer networks

This paper presents a model (inspired by another model) to calculate water temperature in free-surface flow with two main innovations: the convective heat transfer occurs only at the wetted perimeter of pipes, and the model was integrated to commercial software used for hydraulic calculations in drainage systems. Given these innovations, we...

Tailoring the Mechanical Properties of Titanium Alloys via Plasticity Induced Transformations

Titanium alloys possess good corrosion properties, high temperature stability and high strength-to-weight ratio. However, they fall short in providing the optimum strength-ductility relation in the most demanding structural applications, including the aerospace sector. Inspired by the possibility of enhancing the strength-ductility relation in...

Analysis and modeling of the seasonal South China Sea temperature cycle using remote sensing

3D temperature modeling for the South China Sea using remote sensing data

The South China Sea's (SCS) seasonal, large-scale temperature cycle is governed to a large extend by the monsoon. This phenomenon modulates the large-scale circulation, transport and mixing as well as the exchange processes with the Pacific Ocean and the East China Sea. Also, significant variations in net surface heat flux will contribute to the...
