The presented research evaluates the concept of providing an airport’s Air Traffic Control with a bird strike advisory system. Such a system informs the controller about current and predicted bird movements in the arrival and departure corridors. Based on this information, the controller can decide to delay or reroute air traffic in order to...

In this work, we demonstrate that a preferential Ga-for-Zn cation exchange is responsible for the increase in photoluminescence that is observed when gallium oleate is added to InZnP alloy QDs. By exposing InZnP QDs with varying Zn/In ratios to gallium oleate and monitoring their optical properties, composition, and size, we conclude that Ga3+...

The extraction of natural gas in the north of The Netherlands has led to soil subsidence and the occurrence of earthquakes. Residents worry about the safety of their families and the saleability of their dwelling and might want to move. The goal is to examine whether the earthquakes are related to the intention to move. A survey among...

The Dutch social rental sector often serves as an example for other countries as a result of its large share and good quality housing. However, many things have changed in the sector in recent years. After 2011, the central government has regained its control over the housing associations. This was needed after the unacceptable amount of...

Aircraft mass is a crucial piece of information for studies on aircraft performance, trajectory prediction, and many other ATM topics. However, it is a common challenge for researchers who have no access to this proprietary information. Previously, several studies have proposed methods to estimates aircraft weight, most of which are focused on...

Open access to flight data from ADS-B (Automatic Dependent Surveillance Broadcast) has provided researchers more insights for air traffic management than aircraft tracking alone. With large quantities of trajectory data collected from a wide range of different aircraft types, it is possible to extract accurate aircraft performance parameters....

Wind is an important parameter in many air traffic management researches, as it often introduces significant uncertainties in aircraft performance studies and trajectory predictions. Obtaining accurate wind field information has always been a challenge due to the availability of weather sensors. Traditionally, there is no direct method to...

To investigate the contradicting findings of previous studies that investigated ADS-B quality, a study was per-formed to analyze the data and signal quality of ADS-B. For this study, a large dataset of raw ADS-B messages was analyzed, regarding the quality of the data and the signal, differentiating between internal and external sources of...

AUTOMATIC dependent surveillance–broadcast (ADS-B) [1,2] is widely implemented in modern commercial aircraft and will become mandatory equipment in 2020. Flight state information such as position, velocity, and vertical rate are broadcast by tens of thousands of aircraft around the world constantly using onboard ADS-B transponders. These data...

This paper explains the development of the urban housing system in China from 1949 to 2011 with an emphasis on the factors driving housing inequality in each policy period. We argue that the logic underpinning the housing policy had shifted from socialist redistribution to the stimulation of growth in the process of market economy reform and has...

The Spanish home ownership sector has been hit hard by the economic crisis. Repossessions stand at around half a million in the period from 2008 to 2014. This article investigates how the authorities, both at the level of the Spanish state and of the autonomous communities (regions), have responded to this problem. We investigated whether...

Colloidal quantum dots (QDs) show great promise as LED phosphors due to their tunable narrow-band emission and ability to produce high-quality white light. Currently, the most suitable QDs for lighting applications are based on cadmium, which presents a toxicity problem for consumer applications. The most promising cadmium-free candidate QDs...
