Het aantonen of corrosie gedetecteerd kan worden in de omtrek richting van pijpleidingen. Er wordt gebruik gemaakt van zeer dispersieve akoestische plaatgolven genaamd Lamb waves. Als transducers worden er Elektro-Magnetische Akoestische Transducers gebruikt. Corrosion inside pipelines caused by salt …

Although permeable pavements have been used all over the world in recent years to infiltrate and treat stormwater, only limited research has been undertaken to investigate and compare the long-term performance of these sustainable urban drainage system devices. This paper presents the results of an extensive …

Distribution structures and distribution centre (DC) locations are essential for logistics companies to optimise logistics costs and service levels. This paper reviews Supply Chain Management (SCM), Geography and Economic Geographic literature on distribution structure and DC locations decision-making. …

This work provides a feasibility study on estimating the 3-D locations of several thousand miniaturized free-floating sensor platforms. The localization is performed on basis of sparse ultrasound range measurements between sensor platforms and without the use of beacons. We show that this task can be …

Designing a green gas supply to meet a regional seasonal demand: a case study.One of the issues concerning the replacement of natural gas by green gas is the seasonal pattern of the gas demand. When constant production is assumed, this may limit the injected quantity of green gas into a gas grid to the …

This paper outlines an investigation into the updating of fatigue reliability through inspection data by means of structural correlation. The proposed methodology is based on the random nature of fatigue fracture growth and the probability of damage detection and introduces a direct link between predicted …

Background Several footwear design characteristics are known to have detrimental effects on the foot. However, one characteristic that has received relatively little attention is the point where the sole flexes in the sagittal plane. Several footwear assessment forms assume that this should ideally …

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 …

This report outlines the origin of aberrations in a Low Energy Electron Microscope (LEEM) and how to measure and automatically correct them. The aberrations in a LEEM are mainly caused by the cathode objective lens and are a limiting factor for the achievable resolution. To optimise the resolution of …

Fragmentation of the environment affects the dispersal of Eurasian lynx (Lynx lynx). This also occurs in the Harz region, in central Germany, where in 2000 the Luchsprojekt Harz started reintroducing the Eurasian lynx. This constantly growing population causes lynx dispersal including high traffic volume …
