Comparison of Kansei Engineering and AttrakDiff to Evaluate Kitchen Products
Kansei Engineering can be used to create scales to measure perceptions and evaluations of products in a particular context. To what extent do specifically constructed Kansei scales reveal more information about a product than a more generic, prestructured instrument, such as AttrakDiff? This case study identified relevant affective and pragmatic Kansei attributes that influence the purchase of a range hood (cooker hood). 102 customers rated the extent to which each of 10 range hoods possessed these attributes. In addition, AttrakDiff was used to measure hedonic and pragmatic quality perceptions. There was a general high correspondence between AttrakDiff and Kansei. While Kansei provided richer and more specific feedback, it was more resource intensive to carry out
Formation History of HD106906 and the Vertical Warping of Debris Disks by an External Inclined Companion
HD106906 is a planetary system that hosts a wide-orbit companion, as well as
an eccentric and flat debris disk, which hold important constraints on its
formation and subsequent evolution. The recent observations of the companion
constrain its orbit to be eccentric and inclined relative to the plane of the
debris disk. Here, we show that, in the presence of the inclined companion, the
debris disk quickly ( Myr) becomes warped and puffy. This suggests
that the current configuration of the system is relatively recent. We explore
the possibility that a recent close encounter with a free floating planet could
produce a companion with orbital parameters that agree with observations of
HD106906b. We find that this scenario is able to recreate the structure of the
debris disk while producing a companion in agreement with observation.Comment: 13 pages, 7 figures. Accepted for publication in Ap

Insertion devices for the Advanced Light Source at LBL
The Advanced Light Source (ALS) at the Lawrence Berkeley Laboratory will be the first of the new generation of dedicated synchrotron light sources to be put into operation. Specially designed insertion devices will be required to realize the high brightness photon beams made possible by the low emittance of the electron beam. The complement of insertion devices on the ALS will include undulators with periods as short as 3.9 cm and one or more high field wigglers. The first device to be designed is a 5 m long, 5 cm period, hybrid undulator. The goal of very high brightness and high harmonic output imposes unusually tight tolerances on the magnetic field quality and thus on the mechanical structure. The design process, using a generic structure for all undulators, is described. 5 refs., 4 figs., 1 tab
