The discovery of radiation belts dates back to the dawn of the space age when theknowledge of the physical properties of the magnetosphere was still in its infancy. InFebruary 1958 the first U.S. satelliteExplorerI1carried a Geiger–Müller instrumentthat was designed to measure cosmic radiation. It indeed did so until the space craft reached the altitude of about 700 km when the instrument my…
MEC provides a distributed computing environment by placing compute and storageresources closer to the consumer or enterprise end user. The termMECwas first intro-duced in 2013, when Nokia Siemens Networks and IBM developed a platform calledApplication Service Platform for Networks to allow mobile operators to deploy, run,and integrate applications at the edge of the network [2]. In 2014, the M…
Air distribution affects air quality, thermal environment, and work efficiency. The goal of ventilation is to provide occupants with clean air for breathing and thermal comfort. In essence, ventilation means controlling air movement in rooms or built environments. It is the science of studying the interaction of natural convection and organized cur…
Levees are typically very long structures built above the natural ground level to either channel water or prevent it from flowing through. Excluding those built along canals, levees are designed to protect certain areas against river or marine flooding. This handbook only addresses riverine flood protection levees that pro-vide partial or total protection against floodplain inundation.As we wil…
Traditional concrete has a limited fluidity and needs to be actively compacted. Its performance has now been scientifically surpassed by highly technological mixtures based on multiple blends of powders combined with specially designed admixtures, showing rheological properties that make the fresh material self-compacting [1]. In spite of its many advantages (reduced energy consumpti…
Civil engineering has made an inestimable contribution to modern life, providing the crucial expertise behind our vast transportation systems and the wide array of built structures where we work, study, and play. In this Very Short Introduction, engineer David Muir Wood turns a spotlight on a field that we often take for granted. He sheds light on the nature and importance of civil engineering …
Currently, complexity is derived from reports provided by the controllers andpilots involved in the incidents, from which the mid-air collision risk is estimated.These incidents are extremely rare events, which make them infeasible to deriveany reliable statistics. Furthermore, not all incidents are reported, making it diffi-cult to infer how many true incidents have really occurred. Finally, t…
MRO companies strive to stay competitive Maintenance, Repair and Overhaul (MRO) companies constantly strive to stay competitive and respond to the increasing demand for short and predictable air-craft turnaround times. As they work towards shorter and better controlled aircraft down times and lower maintenance costs, they have identified process op-timization as the key element for innovation i…
Aviation has played an important part in shaping Australia’s culture and history through the course of the twentieth century. Australia embraced aviation from its earliest days, eagerly responding to its potential to cover a challenging country, to bring far-flung communities closer and to provide services that could not be delivered any other way. Add the romance of pioneer heroes, the vital…
n recent years, the Internet of Things (IoT) has been gathering pace andunleashing a very disruptive potential. According to Gartner, nearly fivebillion “things” were connected in 2015 and the number will reach 50 billionby 2020. However, the IoT does not only have a disruptive power but it isalso one of the main drivers and enablers for the Digitising European Industry…
