Sedimentation devices have been widely implemented to remove suspended solids and attached pollutants from stormwater before entering surface waters. The treatment performance of these best management practices (BMPs) on fine particles is rarely investigated in a standardized way. To overcome this information …

A Quad Focus GridPix Gaseous Tracking Detector is under construction, to allow calibration and test beam measurements to validate the working principles of the (quad) GridPix detectors while using a focused electric field. The development is well on its way: both measurements should be able to be conducted …

Stormwaters, flowing into storm sewers, are known to significantly increase the annual pollutant loads entering urban receiving waters and this results in significant degradation of the receiving water quality. Knowledge of the characteristics of stormwater pollution enables urban planners to incorporate …

Human exposure to polybrominated diphenyl ethers (PBDEs) can occur via ingestion of indoor dust, inhalation of PBDE-contaminated air and dust-bound PBDEs. However, few studies have examined the pulmonary toxicity of particle-bound PBDEs, mainly due to the lack of an appropriate particle-cell exposure …

In het kader van de afstudeerstage voor de opleiding Technische Natuurkunde aan de Haagse Hogeschool is er een opdracht uitgevoerd bij de onderzoeksgroep Charged Particle Optics aan de TU Delft. De opdracht is een onderdeel van het mini-NAIS project en beslaat het ontwerpen, opbouwen en testen van de …

The Pierre Auger group is studying ultra-high energy cosmic rays. Cosmic rays are charged particles which permanently hit and penetrate the atmosphere of the Earth. They will at a certain moment collide with nuclei in the atmosphere, like nitrogen. The results of such an interaction are new particles, …

Dit document behandelt het ontwikkelingsproces van een 3D animatie en de bijbehorende technische deelproducten. Tijdens dit proces wordt er gekeken of er een antwoord gevonden kan worden op de hoofdvraag: "Is het mogelijk om binnen een 3D pakket het complexe groeiproces van organoids procedureel te animeren?". …

The authors investigate performance of sensor selection schemes in a target tracking scenario. In current NLDA research on air and surface picture compilation with a network of naval radar systems a sensor selection approach is based on the Particle Filter target tracking technique and a minimisation …
