CEAS Aeronautical Journal
No full textThe CEAS Aeronautical Journal has been created under the umbrella of CEAS to provide an appropriate platform for excellent scientific publications submitted by scientists and engineers. The German Aerospace Center (DLR) and the European Space Agency (ESA) support the Journal.
The Journal is devoted to publishing results and findings in all areas of aeronautics-related science and technology as well as reports on new developments in design and manufacturing of aircraft, rotorcraft, and unmanned aerial vehicles. Of interest are also (invited) in-depth reviews of the status of development in specific areas of relevance to aeronautics, and descriptions of the potential way forward. Typical disciplines of interest include flight physics and aerodynamics, aeroelasticity and structural mechanics, aeroacoustics, structures and materials, flight mechanics and flight control, systems, flight guidance, air traffic management, communication, navigation and surveillance, aircraft design, rotorcraft and propulsion.
The Journal publishes peer-reviewed original articles, (invited) reviews and short communications
Towards real world neuroscience: the impact of virtual and augmented reality techniques on the study of human performance and sense of presence.
Full text linkVirtual and Augmented reality systems are rapidly evolving. Their technical development is accompanied by a spreading of applications in fields such as architecture, design, digital marketing, education, entertainment, gaming, robotics, fine arts, military and medicine training, engineering and research. Those tools, requiring 8 years ago investment in the order of tens of thousands of US dollars (Bohil, Alicea, & Biocca, 2011) can boast nowadays easier economical accessibility and predicted market size in the next 5 years ranging from 50 to 300 billion (summary of sources). Having regard to the forthcoming large-scale adoption, it is beyond necessary, from a neuroscientific perspective, to investigate the impact of VR and AR technology on human cognition and performance. Therefore, monitoring the interplay between these devices and our brain dynamics in the short and long term and across their development leaps will be crucial to ensure their correct and safe usage in research and beyond. This could pave the way to new research paradigms and commercial applications, granting users the right experience for their needs whether they will need to train for a complex surgical intervention along with an artificial agent or just get the maximum excitement from an immersive sensorial journey.
The first introductory chapter will discuss the contribution of virtual and augmented reality as tools for the study of human cognition and performance and the need, arising from an "embodied" vision of cognition, for a transition towards experimental paradigms that allow neuroscientist to study subjects that interact in a realistic environment through spontaneous and natural actions

AURALIZATION OF NOISE IN A VIRTUAL REALITY AIRCRAFT CABIN FOR PASSENGER WELL BEING USING HUMAN CENTRED APPROACH
No full textSPATIAL SOUND SYSTEM TO AID INTERACTIVITY IN A HUMAN CENTRED DESIGN EVALUATION OF AN AIRCRAFT CABIN ENVIRONMENT
Full text linkThere is a lot of research towards the concept of 3D sound in virtual reality environments. With the
incipient growth in the significance of designing more realistic and immersive experiences for a Human Centred Design (HCD) approach, sound perception is believed to add an interactive element in maximizing the human perspective. In this context, the concept of an audio-visual interaction model between a passenger and a crew member in an immersive aircraft cabin environment is studied and presented in this paper. The study focuses on the design and usability of spatial sources as an interactive component in a regional aircraft cabin design for Human in the Loop evaluation. Sound sources are placed among the virtual manikins acting as passengers with the aim of building a realistic virtual environment for the user enacting the role of a crew member. The crew member, while walking throughthe cabin can orient and identify the position of the sound source inside the immersive Cabin environment. We review the 3D sound approaches and cues for sound spatialization in a virtual environment and propose that audio-visual interactivity aids the immersive Human centred design analysis
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
