Visualising ergonomics data for design
Existing ergonomics data are not effectively used by designers; this is mainly because the data are not presented in a designer-friendly format. In order to help designers make better use of ergonomics data, we explored the potential of representing existing ergonomics data in a more dynamic and visual way, and making them look more relevant to design. The Cambridge Engineering Selector (CES) was adopted to turn static ergonomics data into manipulative and comparative data sets. Contextual information in a visual format was added; clearer illustrations and scenarios relevant to design were developed; design case studies were compiled and linked to the relevant ergonomics data sets – the process resulted in a new design support tool: the ErgoCES. The tool was consequently brought to both design students and professionals for evaluation. The results suggested that the ErgoCES had helped making ergonomics data more accessible to designers, and many new features (e.g. scenarios and case studies) were highly valued by the designers. Among the participants, 100% of the design students and 79% of the professionals indicated that they would use the tool when it becomes widely available.The research project is funded by the Engineering and Physical Sciences Research Council, Grant EP/F0 32145/1. The authors would like to thank all the participants for helping evaluating the tool.

The Rogue Wave and breather solution of the Gerdjikov-Ivanov equation
The Gerdjikov-Ivanov (GI) system of and is defined by a quadratic
polynomial spectral problem with matrix coefficients. Each element
of the matrix of n-fold Darboux transformation of this system is expressed by a
ratio of determinant and determinant of
eigenfunctions, which implies the determinant representation of and
generated from known solution and . By choosing some special
eigenvalues and eigenfunctions according to the reduction conditions
, the determinant representation of provides
some new solutions of the GI equation. As examples, the breather solutions and
rogue wave of the GI is given explicitly by two-fold DT from a periodic "seed"
with a constant amplitude.Comment: 8 figures, 17 page
Resonant Leptogenesis and Verifiable Seesaw from Large Extra Dimensions
In the presence of large extra dimensions, the fundamental scale could be as
low as a few TeV. This yields leptogenesis and seesaw at a TeV scale.
Phenomenologically two TeV-scale Majorana fermions with a small mass split can
realize a resonant leptogenesis whereas a TeV-scale Higgs triplet with a small
trilinear coupling to the standard model Higgs doublet can give a verifiable
seesaw. We propose an interesting scenario where the small parameters for the
resonant leptogenesis and the type-II seesaw can be simultaneously generated by
the propagation of lepton number violation from distant branes to our world.Comment: 5 pages. More discussions and references. Published in PR
The Effectiveness of Facilitated Business-to-Business Word-of Mouth Marketing Strategies on Target Participants’ Information Sharing Behavior
This study examines the impact of facilitated business-to-business (B2B) word-of-mouth (WOM) on participants' information transmission decisions. We also examine characteristics of WOM participants and determine the types of participants who spread information. Understanding WOM participants' information sharing decisions is extremely important to agribusinesses using WOM in their marketing mix. For an expendable crop input, the most important factor in determining whether producers share WOM initiative information with peers is how often they are asked for advice by their peers. In contrast, for an expendable companion animal product the most important factor in determining whether veterinarians share WOM initiative information with peers is whether they had a satisfactory experience in the WOM initiative.facilitated B2B WOM, effectiveness of facilitated B2B WOM, indirect impact of facilitated B2B WOM, agribusiness firms’ information sharing decisions, Agribusiness, Industrial Organization, Marketing, Teaching/Communication/Extension/Profession, Q10, Q13,
Tunable Frequency Comb Generation from a Microring with a Thermal Heater
We demonstrate a novel comb tuning method for microresonator-based Kerr comb
generators. Continuously tunable, low-noise, and coherent comb generation is
achieved in a CMOS-compatible silicon nitride microring resonator.Comment: submitted to CLEO201
