Viability and preliminary design of an airport in Europe

An airport is the infrastructure from where the vast majority of air operations start. Planes begin their journeys by taking off at one airport and ending them landing at another. In this study, the feasibility of locating said infrastructure in an exact country and area of Europe has been analyzed in order to carry out a preliminary design based on the demand that this location generates and the previous conditions to which it is subjected. The first thing that has to be investigated is the location of the airport. To this end, the European countries have been analyzed using two comparative methods that assess aspects of interest for the study and it has been possible to obtain that Hungary, specifically, in the city of Sarbogard, is the country considered with the greatest potential to locate the airport. The next point to be discussed is the Traffic Demand Analysis. In any project based on the construction or creation of a new platform or a new business, it is necessary to estimate the demand it will have. To design the airport, a study of both passenger and aircraft traffic has been, first, carried out to obtain the capacity it will cover and to be able to carry out the preliminary design. The definition of the capacity in a horizon scenario, that will support the infrastructure, is obtained by investigating the area where it will be located as well as the Budapest Airport taken as a reference for the analysis. The purpose established has been to absorb part of the air traffic at the Hungarian capital airport. After analyzing the traffic and deciding which complete low-cost airlines would be accommodated in a realistic scenario, different data of interest is obtained, such as the month and the peak day, the busy day and the peak hour, and the number of operations and passengers per year, from the base year that would be 2027 to a horizon scenario. Finally, to obtain a preliminary design of the airport, the so-called year of design, 2036 (intermediate scenario) has been taken as a reference. Based on the annual, peak day and peak hour traffic results in this design year, the air side and the ground side of the airport can be designed using the Airbus A321 Neo (ACF) as the reference aircraft. The design is governed by what the ICAO dictates in Annex 14, for the design of the runway, taxiways and parking aprons (air side) and, for the land side, it has been used the IATA established manual, where the organization explains how to estimate passenger ows and thus be able to define the areas that make up the terminal building and the terminal as a whole. It should be noted that a preliminary design of the main aircraft and passenger movement areas is carried out, elements such as easements, visual aids and other airport buildings would be defined in a more complete design of the airport. In summary, carrying out a feasibility study and a preliminary design of an infrastructure, as such, is a squared process, in which everything must be justified in detail. But, apart from the difficulties encountered, being able to study everything that the construction of an airport infrastructure implies is of great interest because, in the end, all the factors that affect and determine the future, of the designed airport, are analyze

Resource request dispatch in standalone and federated MEC systems: a matching game approach

This paper has been presented at : IEEE Wireless Communications and Networking Conference. 15-19 April 2019 Marrakech, MoroccoMulti-access edge computing (MEC) system con-sisting of geographically-distributed heterogeneous servers can provide low-latency virtualized resource to support computation offloading of smart devices. When bulk offloading requests comes to an MEC system, how to dispatch requests to servers so as to maximize divergent objectives of MEC service providers and users is challenging. The problem further involves money transfer when different MEC service providers can share resource to each other. In this paper, we address request dispatch issues in a standalone MEC and among federated MEC systems using matching game theory. We have adapted several classical matching algorithms to our problem. Simulation results show that we can serve more requests while still meeting latency constraints. For federated MEC systems, we can also have high revenue.This work was partially supported by the Ministry of Science and Technology, Taiwan, under grant numbers 106-2221-E-009-004 and by the H2020 collaborative Europe/Taiwan research project 5G-CORAL (grant number 761586)

Measuring magnetic fields in galaxies

The magnetic (B) field in the disk of a galaxy may play an important role in the dynamics and evolution of the interstellar medium (ISM). The process by which the interstellar B-field is generated and maintained is not well understood, but the general expectation is that the generated B-field will be toroidal (parallel to the disk of the galaxy). The large-scale B-field threading the cold ISM of external galaxies can be probed via optical and near-infrared (NIR) polarimetric observations. However, scattered light can introduce false-positive B-field detections into these observations and is a source of contamination. This dissertation sets a context for observations of the Milky Way B-field by assessing the degree to which scattered light affects NIR polarimetry and reporting measurements of the B-fields in the disks of several external galaxies. The polarization properties of scattered light were investigated in order to better understand the degree to which scattered light may be a source of contamination in studies of the cold ISM B-field of external galaxies. The optical and NIR polarization of three, nearby, reflection nebulae was observed, and the wavelength dependence of the polarization percentage was measured. This wavelength dependence was found to be related to the characteristics of the scattering dust grain population with the general conclusion that the total amount of polarized, scattered light decreases with increasing wavelength. This analysis was repeated for the scattering-dominated galaxy M82 to test if similar results obtained for galaxies outside the Milky Way. Observations of this object indicate that the total amount of contamination from scattered light in this object is also less at NIR wavelengths than at optical wavelengths, and they confirm that B-field generated polarization can be detected in external galaxies. A sample of edge-on galaxies was observed for NIR polarization to measure the cold ISM B-field there. These observations indicate the likely presence of non-toroidal B-fields, localized, coherent B-field structures, and spiral disk structure detectable via NIR polarimetry. A comparison of the B-fields threading the cold and hot components of the ISM suggests that these B-fields may be dynamically distinct under certain conditions

Interactive archives of scientific data

A focus on qualitative methods of presenting data shows that visualization provides a mechanism for browsing independent of the source of data and is an effective alternative to traditional image-based browsing of image data. To be generally applicable, such visualization methods, however, must be based upon an underlying data model with support for a broad class of data types and structures. Interactive, near-real-time browsing for data sets of interesting size today requires a browse server of considerable power. A symmetric multi-processor with very high internal and external bandwidth demonstrates the feasibility of this concept. Although this technology is likely to be available on the desktop within a few years, the increase in the size and complexity of achieved data will continue to exceed the capacity of 'worksation' systems. Hence, a higher class of performance, especially in bandwidth, will generally be required for on-demand browsing. A few experiments with differing digital compression techniques indicates that a MPEG-1 implementation within the context of a high-performance browse server (i.e., parallized) is a practical method of converting a browse product to a form suitable for network or CD-ROM distribution
