Evaluation of augmented reality tools for the provision of tower air traffic control using an ecological interface design
One of the major problems faced by the growth of air traffic in the last decade is the limited capacity of the runway especially during low visibility procedures (LVP) due to fog and bad weather. To solve this issue, the project \u201cResilient Synthetic Vision for Advanced Control Tower Air Navigation Service Provision\u201d (RETINA) project, a two-years exploratory research project, under SESAR2020 program, proposes to use new Synthetic Vision (SV) and Augmented Reality (AR) technologies for the tower controllers to allow them to conduct safe operations under any Meteorological Conditions while maintaining a high runway throughput, equal to good visibility. In this paper we introduce the Ecological Interface Design (EID) as a methodology to investigate the potential and applicability of SV tools and Virtual/Augmented Reality (V/AR) display techniques for the Air Traffic Control (ATC) service provision by the airport control tower. We explain how the EID framework can be used in RETINA, we experiment the framework on a suitable airport and we provide the EID results comparing normal and LVP conditions with operations using RETINA technologies
Human-in-the-loop evaluation of an augmented reality based interface for the airport control tower
An innovative airport control tower concept based on the use of modern augmented reality technologies has been developed and validated by means of human-in-the-loop experiments in a simulated environment. An optical-based augmented reality interface underpins the proposed concept that consists in providing air traffic control operators in the airport control tower with complete head-up information, as opposed to the current mix of information retrieval through both head-up real view and head-down interfaces. Specific measurement of the time spent by the operator working in either head-up or head-down position, show that the proposal has a clear effect in stimulating the air traffic control operator to work in a head-up position more than in a head-down position, with positive effects on his/her situational awareness and perceived workload, especially when dealing with low visibility conditions operational scenarios
A Quantum-Conceptual Explanation of Violations of Expected Utility in Economics
The expected utility hypothesis is one of the building blocks of classical
economic theory and founded on Savage's Sure-Thing Principle. It has been put
forward, e.g. by situations such as the Allais and Ellsberg paradoxes, that
real-life situations can violate Savage's Sure-Thing Principle and hence also
expected utility. We analyze how this violation is connected to the presence of
the 'disjunction effect' of decision theory and use our earlier study of this
effect in concept theory to put forward an explanation of the violation of
Savage's Sure-Thing Principle, namely the presence of 'quantum conceptual
thought' next to 'classical logical thought' within a double layer structure of
human thought during the decision process. Quantum conceptual thought can be
modeled mathematically by the quantum mechanical formalism, which we illustrate
by modeling the Hawaii problem situation, a well-known example of the
disjunction effect, and we show how the dynamics in the Hawaii problem
situation is generated by the whole conceptual landscape surrounding the
decision situation.Comment: 9 pages, no figure
Design and implementation of eye tracking application for generation of augmented reality content on spatial see through display of remote and virtual control tower (RVT)
Airports are a fundamental node in the aviation system. The growth of this sector undergoes the evolution of the airports
procedures and infrastructures. Air traffic control is considered to be one of the most important activity performed in an
airport. This often involves numerous personnel, construction and maintenance costs etc. With the ongoing digitalisation
process in various fields, the concept of remote and virtual control towers (RVT) has emerged owing to the innovation in this
field. Technologies such as augmented reality (AR) have successfully paved their smooth way to bring in improvements to an
RVT. The current work aims to enhance and improve the controller work in an RVT exploiting the adaption of virtual reality
and AR systems. In particular, this concept is under investigation within the EU funded SESAR project: RETINA (Resilient
Synthetic Vision for Advanced Control Tower Air Navigation Service Provision) and DTT (Digital Technologies for Tower).
AR content generation by virtue of various display technologies are studied and, Optical Spatial See-through displays (O
SSTDs) have been considered for its own advantages in developing this application. One of the necessary requirements of
AR in this configuration is identified as the tracking of the operatorâs point of view (eye-tracking), to provide virtual content
consistent with its real position. Thus, this paper elaborates the design of specific eye-tracking system using Microsoft Kinect
V2 for the virtual control tower application. The need to have binocular vision to use AR content is assessed and the interface
has been tested with few subjects to evaluate the precision of the measurements detected through the proposed solution
Classical Logical versus Quantum Conceptual Thought: Examples in Economics, Decision theory and Concept Theory
Inspired by a quantum mechanical formalism to model concepts and their
disjunctions and conjunctions, we put forward in this paper a specific
hypothesis. Namely that within human thought two superposed layers can be
distinguished: (i) a layer given form by an underlying classical deterministic
process, incorporating essentially logical thought and its indeterministic
version modeled by classical probability theory; (ii) a layer given form under
influence of the totality of the surrounding conceptual landscape, where the
different concepts figure as individual entities rather than (logical)
combinations of others, with measurable quantities such as 'typicality',
'membership', 'representativeness', 'similarity', 'applicability', 'preference'
or 'utility' carrying the influences. We call the process in this second layer
'quantum conceptual thought', which is indeterministic in essence, and contains
holistic aspects, but is equally well, although very differently, organized
than logical thought. A substantial part of the 'quantum conceptual thought
process' can be modeled by quantum mechanical probabilistic and mathematical
structures. We consider examples of three specific domains of research where
the effects of the presence of quantum conceptual thought and its deviations
from classical logical thought have been noticed and studied, i.e. economics,
decision theory, and concept theories and which provide experimental evidence
for our hypothesis.Comment: 14 page
Quantum Experimental Data in Psychology and Economics
We prove a theorem which shows that a collection of experimental data of
probabilistic weights related to decisions with respect to situations and their
disjunction cannot be modeled within a classical probabilistic weight structure
in case the experimental data contain the effect referred to as the
'disjunction effect' in psychology. We identify different experimental
situations in psychology, more specifically in concept theory and in decision
theory, and in economics (namely situations where Savage's Sure-Thing Principle
is violated) where the disjunction effect appears and we point out the common
nature of the effect. We analyze how our theorem constitutes a no-go theorem
for classical probabilistic weight structures for common experimental data when
the disjunction effect is affecting the values of these data. We put forward a
simple geometric criterion that reveals the non classicality of the considered
probabilistic weights and we illustrate our geometrical criterion by means of
experimentally measured membership weights of items with respect to pairs of
concepts and their disjunctions. The violation of the classical probabilistic
weight structure is very analogous to the violation of the well-known Bell
inequalities studied in quantum mechanics. The no-go theorem we prove in the
present article with respect to the collection of experimental data we consider
has a status analogous to the well known no-go theorems for hidden variable
theories in quantum mechanics with respect to experimental data obtained in
quantum laboratories. For this reason our analysis puts forward a strong
argument in favor of the validity of using a quantum formalism for modeling the
considered psychological experimental data as considered in this paper.Comment: 15 pages, 4 figure
The return of Diesel engine in the aeronautic propulsion
The recent developments in piston engine technology have increased performances as specific power and specific fuel consumption; environmental concern and increasing fuel cost
are the main driving factors of this evolution.
New generations of turbo-diesel engines have been developed for automotive applications, being now competitive with their gasoline
counterpart.
The use of Diesel engine for aeronautical propulsion is a discussed topic. In the past few years there have been a number of attempts to produce diesel engines for aircraft/rotorcraft and to this aim the three most important objectives to be pursued are reliability, compactness and low weight to power ratio.
In this paper an outline of the most challenging aeronautical applications for diesel engines and an overview of the most promising technical solutions are provided
Vibroacoustic analysis of an innovative windowless cabin with metamaterial trim panels in regional turboprops
The purpose of this work is to study the possible noise reduction, in terms of sound pressure level, in the passenger cabin of a regional turboprop aircraft under multiple tonal and broadband noise components characterizing the noise generated by the engines during cruise flight conditions. In particular, we want to show the acoustic performances of innovative passive noise and vibration technologies, such as acoustic metamaterials applied to the trim panel of the cabin, in the low-frequency range, from 100 to 300 Hz. Moreover, the removal of windows from the passenger cabin is evaluated, in acoustic terms. Analyses are performed using a numerical tool, Actran, a finite element based software, and a numerical model of a regional aircraft fuselage. According to the results, metamaterials seem to have significant acoustic performances that lead to a reduction in noise and therefore an increase in passenger comfort
