An analytical approximate procedure for a class of conservative single degree-of-freedom nonlinear oscillators with odd non-linearity is proposed. This technique is based on the generalized harmonic balance method in which analytical approximate solutions have rational forms. Unlike the classical harmonic…

The visual and optical anisotropies of metallic and pearlescent samples have been evaluated using a multi-gonio-spectrophotometer and by adapting a gonio-template over the instrument aperture for measuring the relative spectral reflectance factor when the sample is rotated around an axis…

Evidence accumulated over many years illustrates the benefits of work for mental
health, including that of mental health service users. Despite strong evidence of the
effectiveness of the Individual Placement and Support (IPS) approach in enabling this
group to find…

Porous materials are gaining interest due to their potential for storing hydrogen via physisorption. In the present work, two carbon fibres, carbonised at 973 and 1273 K, have been chemically activated with KOH and NaOH, in order to obtain materials…

The impact of environmental practices on firm performance raises an ongoing debate in which the review of the existing literature yields no conclusive results. Different methods have been used to study this relationship and most of the analyses have focused…

If robotic companions are to be used in the near future by aging adults, they have to be accepted by them. In the process of developing a methodology to measure, predict and explain acceptance of robotic companions, we researched the…

GlowBots are small tangible, communicating and interactive robots that show eye-catching visual patterns on a round LED display. This paper details the development of the GlowBots from the early user-oriented design phase, through hardware and software development and onto preliminary…

This article presents a comparative study of Matthew Arnold's 1854 poem "The Scholar-Gipsy" and Anita Desai's 1978 story "Scholm" and Gypsy". Arnold's poem contrasts the single-minded integrity of his central character's search lot redemption through the power of Romany culture,…

This paper explores Heidegger's relevance to SF and proposes links between his philosophy and SF approaches. It also explores phenomenology as a useful concept for SF.
