Fracture Toughness of Aerospace Structures: On the Use of Redundant Lattice Structures

Both experimental and numerical studies have shown that the crack-bridging is one of the most significant mechanism contributing to the fracture toughness of natural materials like nacre and bone. This study aims to explore if additive manufactured lattice structures can be used to bridge fatigue cracks as well, thereby improving the fracture...

Assessing the Accuracy of Water Temperature Determination and Monitoring of Inland Surface Waters Using Landsat 7 ETM+ Thermal Infrared Images

This research evaluates the potential of thermal infrared (TIR) remote sensing to determine and continuously monitor the horizontal water temperature distribution of inland surface water bodies. Usually, monitoring temporal and spatial variability of surface water temperature takes place by measurement networks of in-situ gauges, but these...

Study centres for amsterdam

Due to the digitalisation of study material the future academic library will facilitate only the act of studying. As such, these five new study centres function as embassies of tranquillity in a turbulent city, a place where you can concentrate or socialise with people with a similar purpose. A variety of meticulously proportioned rooms make up...

Foot placement in robotic bipedal locomotion

Human walking is remarkably robust, versatile and energy-efficient: humans have the ability to handle large unexpected disturbances, perform a wide variety of gaits and consume little energy. A bipedal walking robot that performs well on all of these aspects has not yet been developed. Some robots are versatile, others are energy-efficient, and...

Design and Testing of a Haptic Microgripper for Microassembly Applications

The provisioning of digital leased lines in an SDH-based transport network

The time between request and realization of private or leased lines (i.e. provisioning time) has traditionally been very long (i.e. months). To a large extent, this has to do with the inflexibility of the "conventional" transport network. With the availability of Digital Cross-connect Systems (DCS) and other network products based on the...
