Caster-camber relationship in vehicles
No full textA variation in the camber of an automotive wheel is desired to compensate a side-slip force reduction owing to transversely normal load shift when the car is cornering. The camber of a steered wheel can be varied by adjusting caster or/and lean angles which are the representations of steering axis orientation. Thus, adjustable camber can be created by variable caster or/and lean angle. Choosing which parameter among the two angles to be the main source of camber generation is a key starting point and dependent on its different effects. Here, homogeneous transformation is employed to establish camber as a function of caster, lean angle, and steering angle in the general case. A comparison between caster and lean angle based on different criteria is made. The comparison shows that a variable caster is more effective than a variable lean angle in generating a smart camber

Lunar volcanic feature catalog for Dawn
No full textExcept for a number of low-resolution full-globe images
obtained by the Hubble Space Telescope the surface
of Vesta remains largely unknown. New image
data from NASA’s Dawn mission that will arrive at
asteroid Vesta in July 2011 for a 9 month systematic
mapping phase to investigate Vesta’s geology [1]. This
proposal of lunar analogues relies on medium to lowresolution
image data from the Clementine and Lunar
Orbiter missions as well as high-resolution image
data obtained from the Lunar Reconnaissance Orbiter
(LRO), Chandrayaan-1 and Kaguya camera experiments
that are comparable to the expected Dawn
instrument resolutions
Topography of Vesta from Dawn FC stereo images
No full textThe Dawn mission has completed its Survey and High Altitude Mapping Orbit (HAMO) phases at Vesta and is currently in its Low Altitude Mapping Orbit (LAMO) [1]. From the Survey orbit (altitude ~2,700 km) the Dawn Framing Camera (FC) [2] acquired 1,179 clear filter images with a mean im-age resolution of 256 m/pxl whereas from the HAMO orbit (~700 km altitude) there are 2,674 clear filter images with a mean resolution of 63 m/pxl. In both mapping phases the surface was imaged several times under similar illumination conditions (Sun elevation and azimuth), but different viewing conditions (by tilt-ing the spacecraft). This allows to analyze the images stereoscopically and to construct stereo topographic maps. The topography is particularly important, be-cause it is essential for:
• derivation of physical properties of Vesta
• precise ortho-image registration, mosaicking, and map generation of monochrome/color FC images and VIR images
• quantitative geomorphologic analysis and
• precise photometric analysis (from detailed local surface inclination)
Dawn maps the surface composition of Vesta
No full textBy 7-October-2011, the Dawn mission will have
completed Survey orbit and commenced high altitude
mapping of 4Vesta. We present a preliminary
analysis of data acquired by Dawn’s Framing Camera
(FC) and the Visual and InfraRed Spectrometer (VIR)
to map mineralogy and surface temperature, and to
detect and quantify surficial OH. The radiometric
calibration of VIR and FC is described. Background
counting data acquired by GRaND are used to
determine elemental detection limits from
measurements at low altitude, which will commence
in November. Geochemical models used in the
interpretation of the data are described. Thermal
properties, mineral-, and geochemical-data are
combined to provide constraints on Vesta’s
formation and thermal evolution, the delivery of
exogenic materials, space weathering processes, and
the origin of the howardite, eucrite, and diogenite
(HED) meteorites

Dawn Chorus
No full text‘Dawn Chorus’s interaction with the environment is instrumental in the unfolding of the work and is characteristic of Webster’s work. The unpredictable interaction morphs the work from a reflective, silent installation into a vibrating, musical performance creating a unique experience for both the audience and the gallery
honey : kim dawn & christof migone
No full text"One of MIGONE and DAWN’s most ambitious collaborations was staged as part of the CounterPoses performance programme curated by Jim DROBNIK and Jennifer FISHER for Oboro Gallery in Montreal. In this work titled Separate the artist used their bodies, buckets, pots of honey and stewed plums to engage the topics of sexuality and desire and the continuous relationships between purity and danger, pollution and taboo. A small self-published text documenting the event contains twelve photographs of the artists dressed in disposable white suites wearing panda eye-blacking, seated on a floor area covered with aluminum foil and lit by two casually hanging naked light bulbs." -- Artist's website, text by Bruce Barber
