Human centred design and evaluation of cabin interiors for business jet aircraft in virtual reality
In the recent past a growing attention to the passenger is emerging overall in the transport domain. Hence, maximising the quality of travelling from the human\u2019s point of view is a new challenge especially in those fields, such as aeronautics, in which technical efficiency, capacity and sustainability have traditionally driven the design process of systems and subsystems. In this context it is crucial to implement an efficient human centred design process in order to foresee the capability of a specific cabin interiors design of meeting the user\u2019s expectations, including the needs related to comfort and well being. By using virtual reality technologies as a vehicle/platform, it allows the users/passengers to experience the interior environment of the cabin long before the actual development and manufacturing of the full size demonstrator. Due to the complex nature of aerospace programmes, typically taking \u2018many\u2019 years to develop and productionise, technologies which help reduce programme risk and potential delays are hugely beneficial to all partners involved. In this paper we present the results of a virtual reality based evaluation campaign specifically conceived for the collection of potential users\u2019 feedback in the design of innovative and breakthrough solutions for the business jet industry. The main issues have regarded the identification of the expectation for such an elitist population and the creation of a Virtual Environment to explore the entire cabin as a holistic approach and innovative passenger experience. The work has been performed in the framework the Horizon 2020 project CASTLE (Cabin Systems Design Toward Passenger Well-being)
Promoting the consumer voice : the role of Healthwatch Salford's Enter and View programme
The daily business of running a care home means that, outside of regulatory inspections, assessing and improving the user experience can often be forgotten. Healthwatch Salford discuss their process of gaining constructive feedback using their innovative Enter and View programm
Evidence of resource partitioning between humpback and minke whales around the western Antarctic Peninsula
Author Posting. © The Author(s), 2009. This is the author's version of the work. It is posted here by permission of John Wiley & Sons for personal use, not for redistribution. The definitive version was published in Marine Mammal Science 25 (2009): 402-415, doi:10.1111/j.1748-7692.2008.00263.x.For closely related sympatric species to coexist, they must differ to some
degree in their ecological requirements or niches (e.g., diets) to avoid inter-specific
competition. Baleen whales in the Antarctic feed primarily on krill, and the large
sympatric pre-whaling community suggests resource partitioning among these species or
a non-limiting prey resource. In order to examine ecological differences between
sympatric humpback and minke whales around the Western Antarctic Peninsula, we
made measurements of the physical environment, observations of whale distribution, and
concurrent acoustic measurements of krill aggregations. Mantel’s tests and Classification
and regression tree models indicate both similarities and differences in the spatial
associations between humpback and minke whales, environmental features, and prey.
The data suggest (1) similarities (proximity to shore) and differences (prey abundance
versus deep water temperatures) in horizontal spatial distribution patterns, (2)
unambiguous vertical resource partitioning with minke whales associating with deeper
krill aggregations across a range of spatial scales, and (3) that interference competition
between these two species is unlikely. These results add to the paucity of ecological
knowledge relating baleen whales and their prey in the Antarctic and should be
considered in conservation and management efforts for Southern Ocean cetaceans and
ecosystems.This

Dirac operator on -Minkowski space bicovariant differential calculus and deformed U(1) gauge theory
Derivation of -Poincare bicovariant commutation relations between
coordinates and 1-forms on -Minkowski space is given using Dirac
operator and Allain Connes formula. The deformed U(1) gauge theory and
appearance of an additional spin 0 gauge field is discussed
Generationing development
The articles in this special issue present a persuasive case for accounts of development to recognise the integral and fundamental roles played by age and generation. While the past two decades have witnessed a burgeoning of literature demonstrating that children and youth are impacted by development, and that they can and do participate in development, the literature has tended to portray young people as a special group whose perspectives should not be forgotten. By contrast, the articles collected here make the case that age and generation, as relational constructs, cannot be ignored. Appropriating the term ‘generationing’, the editors argue that a variety of types of age relations profoundly structure the ways in which societies are transformed through development – both immanent processes of neoliberal modernisation and the interventions of development agencies that both respond and contribute to these. Drawing on the seven empirical articles, I attempt to draw some of the ideas together into a narrative that further argues the case for ‘generationing’ but also identifies gaps, questions and implications for further research
Extending the Ehresmann-Schein-Nambooripad Theorem
We extend the `join-premorphisms' part of the Ehresmann-Schein-Nambooripad
Theorem to the case of two-sided restriction semigroups and inductive
categories, following on from a result of Lawson (1991) for the `morphisms'
part. However, it is so-called `meet-premorphisms' which have proved useful in
recent years in the study of partial actions. We therefore obtain an
Ehresmann-Schein-Nambooripad-type theorem for meet-premorphisms in the case of
two-sided restriction semigroups and inductive categories. As a corollary, we
obtain such a theorem in the inverse case.Comment: 23 pages; final section on Szendrei expansions removed; further

Companion problems in quasispin and isospin
We note that the same mathematical results apply to problems involving
quasispin and isospin, but the problems per se are different. In the quasispin
case, one deals with a system of identical fermions (e.g. neutrons) and address
the problem of how many seniority conserving interactions there are. In the
isospin case, one deals with a system of both neutrons and protons and the
problem in question is the number of neutron-proton pairs with a given total
angular momentum. Other companion problems are also discussed.Comment: 12 pages, Latex; some additions in section II and a brief summary at

Decay Rate of Triaxially-Deformed Proton Emitters
The decay rate of a triaxially-deformed proton emitter is calculated in a
particle-rotor model, which is based on a deformed Woods-Saxon potential and
includes a deformed spin-orbit interaction. The wave function of the
ground state of the deformed proton emitter Ho is obtained
in the adiabatic limit, and a Green's function technique is used to calculate
the decay rate and branching ratio to the first excited 2 state of the
daughter nucleus. Only for values of the triaxial angle
is good agreement obtained for both the total decay rate and the 2
branching ratio.Comment: 19 pages, 4 figure
