TL;DR: In this paper, an exact dynamic stiffness matrix for a twisted Timoshenko beam is developed in order to investigate its free vibration characteristics, and the resulting stiffness matrix is used with particular reference to the Wittrick-Williams algorithm to compute the natural frequencies and mode shapes of a twisted timoshenko beam with cantilever end condition.

TL;DR: Several important digital processing techniques for optical-fiber sensor systems that use electronically scanned white-light interferometry are presented, which are able to increase greatly the dynamic range of the measurement under a low signal-to-noise ratio environment.
Abstract: Several important digital processing techniques for optical-fiber sensor systems that use electronically scanned white-light interferometry are presented. These include fringe restoration, fringe-order identification, and resolution enhancement techniques. A pure low-coherence interference fringe pattern is restored by dividing, pixel by pixel, the beam intensity profile from the signal. The central (zero-order) fringe of the pattern is identified by using a centroid algorithm. A linear interpolation or a localized centroid algorithm is used to enhance further the phase resolution. Theoretical analyses, computer simulations, and experimental verifications have shown that these techniques are able to increase greatly the dynamic range of the measurement under a low signal-to-noise ratio environment.

01 Oct 1998TL;DR: Research into semi-automatic generation of scenarios for validating software-intensive system requirements is reported, which describes a computational mechanism for deriving use cases from object system models, simple rules to link actions in a use case, taxonomies of classes of exceptions which give rise to alternative courses in scenarios.
Abstract: This paper reports research into semi-automatic generation of scenarios for validating software-intensive system requirements. The research was undertaken as part of the ESPRIT IV 21903 ‘CREWS’ long-term research project. The paper presents the underlying theoretical models of domain knowledge, computational mechanisms and user-driven dialogues needed for scenario generation. It describes how CREWS draws on theoretical results from the ESPRIT III 6353 ‘NATURE’ basic research action, that is object system models which are abstractions of the fundamental features of different categories of problem domain. CREWS uses these models to generate normal course scenarios, then draws on theoretical and empirical research from cognitive science, human-computer interaction, collaborative systems and software engineering to generate alternative courses for these scenarios. The paper describes a computational mechanism for deriving use cases from object system models, simple rules to link actions in a use case, taxonomies of classes of exceptions which give rise to alternative courses in scenarios, and a computational mechanism for generation of multiple scenarios from a use case specification.

TL;DR: The results from this study can be used to help inform local authorities who are considering the development of their recycling schemes and associated promotional campaigns based on an understanding of their socio-demographic profile as mentioned in this paper.
Abstract: Many UK local authorities, looking to meet their regulatory recycling targets, have opted for voluntary kerbside collection schemes for source segregated recyclables from households. The success of a recycling service is highly dependant on the number of people who participate in the service and the frequency of its use. High participation rates are therefore an essential component of any effective kerbside collection scheme. It is commonly accepted that recycling behaviour is strongly influenced and motivated by personal opinions as well as external issues such as access and convenience. This paper characterises the recycling attitudes within West Oxfordshire, UK, and compares them with the results from a previous study conducted during 2003 in Brixworth, in Daventry, UK. From 1st April 2004, West Oxfordshire District Council, expanded its kerbside collection scheme for dry recyclables, adding cardboard, batteries, aerosols and mixed plastics to the already collected recyclables (paper, glass, textiles and metals) and increasing the frequency from fortnightly to weekly In this study, the recycling attitudes and behaviour of a cross-sectional socio-economic sample from households from West Oxfordshire, is investigated. It is observed that the propensity to recycle varies between individuals and socio-economic areas, and that recycling is influenced by concern for future generations, the need to bury less waste in landfills, and the fact that recycling saves resources and protects the environment. The results from this study can be used to help inform local authorities who are considering the development of their recycling schemes and associated promotional campaigns based on an understanding of their socio-demographic profile.

TL;DR: Understanding of the structure of mutualistic relationships is extended into previously unexplored taxonomic and physical realms, and how nestedness analysis can be applied to the conservation of obligate species interactions is suggested.
Abstract: The interaction structure of mutualistic relationships, in terms of relative specialization of the partners, is important to understanding their ecology and evolution. Analyses of the mutualistic interaction between anemonefish and their host sea anemones show that the relationship is highly nested in structure, generalist species interacting with one another and specialist species interacting mainly with generalists. This supports the hypothesis that the configuration of mutualistic interactions will tend towards nestedness. In this case, the structure of the interaction is at a much larger scale than previously hypothesized, across more than 180° of longitude and some 60° of latitude, probably owing to the pelagic dispersal capabilities of these species in a marine environment. Additionally, we found weak support for the hypothesis that geographically widespread species should be more generalized in their interactions than species with small ranges. This study extends understanding of the structure of mutualistic relationships into previously unexplored taxonomic and physical realms, and suggests how nestedness analysis can be applied to the conservation of obligate species interactions.
