Heterogeneous and incomplete datasets are common in many real-world applications. The probabilistic nature of the Generative Topographic Mapping (GTM), which only handles complete continuous data originally, offers the ability to extend it to also visualise mixed-type and missing data as suggested in (Bishop et al., 1998a). This paper describes this generalisation of GTM and assesses the result...

We currently know little of the role of the corporate human resource (HR) function in multinational corporations regarding global talent management (GTM). GTM is explored here from two perspectives: increasing global competition for talent, and new forms of international mobility. The first considers the mechanisms of GTM, and the second, individual willingness to be mobile, especially in emerg...

This paper describes our participation in the INTERSPEECH 2009 Emotion Challenge [1]. Starting from our previous experience in the use of automatic classification for the validation of an expressive corpus, we have tackled the difficult task of emotion recognition from speech with real-life data. Our main contribution to this work is related to the classifier sub-challenge, for which we tested ...

Purpose: To evaluate the safety and efficacy of limbal relaxing incisions (LRIs) for corneal astigmatism correction during phacoemulsification Methods: 24 eyes of 24 patients with the mean age of 65.71 years (range: 55 to 83 years) with senile cataracts and mean corneal astigmatism of 1.9±0.83 diopters (D) (range: 1.5 to 3.5 D) were included in this study. All LRIs were performed during phacoem...

[1] From gravity and topography data collected by the Mars Global Surveyor spacecraft we calculate gravity/topography admittances and correlations in the spectral domain and compare them to those predicted from models of lithospheric flexure. On the basis of these comparisons we estimate the thickness of the Martian elastic lithosphere (Te) required to support the observed topographic load sinc...

There is an optimization method for the geometric correction of Landsat images, which uses a simulated direct solar irradiance image made from a digital elevation model (DEM) and a solar direction to determine parameters of the geometric transfer equations. The optimization method is quite simple, and also allows us high accuracy geometric correction in sub-pixel order. However, promising in pr...

In satellite images over rugged terrain, we can find some topographic effect entangled with atmospheric effects [1]. Without correcting these effects, it is difficult to evaluate the satellite images for land cover classification or multi-temporal monitoring of natural environment. Iikura[2] derived a unified simple correction formula (DN − B)/(cosβ + C) from a physical model of signal detected...

Purpose: To search evidence and determine whether PRK (Photo Refractive Keratectomy) or LASIK (Laser in Situ Keratomileusis) produce a better outcome of laser vision correction for patients with atypical topography of cornea. Setting: Electronic search of laser vision correction related studies on Cochrane Library, Medline and PubMed. Method: The search was conducted over Cochrane Library, Emba...
