The high spatial resolution of QuickBird satellite images makes it possible to show spatial variability at fine details. However, the effect of topography-induced illumination variations become more evident, even in moderately sloped areas. Based on a high resolution (1 m) digital elevation model generated with high-frequency real-time kinematic global position system measurements, this study a...

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 ...

Remote sensing of rugged terrain is hampered by topographic effects on spectral signatures. The purpose of this study was to attempt normalization of the topographic effect encountered when analyzing Landsat Thematic Mapper (TM) imagery in the Rocky Mountains. Two normalization techniques were performed on a subscene of a TM image of Rocky Mountain National Park. The first technique was a band ...

This paper reports the response of trabecular meshwork (TM) endothelial cells to various topographical cues at microscale and nanoscale. Cells are cultured on substrates with aligned and random features fabricated using electrospinning and microfabrication. The expression of myocilin, a characteristic protein of TM cells, is examined. The results show that all the topographic surfaces up-regula...

Complex interactions between topographic heterogeneity, climatic and environmental gradients, and thermal niche conservatism are commonly assumed to indicate the degree of biotic diversification in montane regions. Our aim was to investigate factors that disrupt gene flow between populations and to determine if there is evidence of downslope asymmetric migration in highland frogs with wide elev...

The direct topographic effect (DTE) and indirect topographic effect (ITE) of Helmert's 2nd method of condensation are computed using the digital elevation model (DEM) SRTM30 in 30 arc-seconds globally. The computations assume a constant density of the topographic masses. Closed formulas are used in the inner zone of half degree, and Nagy's formulas are used in the innermost column to treat the ...

Spatial and temporal characteristics of lexico-semantic retrieval are frequently examined with semantic context (i.e., priming) paradigms. These paradigms measure context (i.e., priming) effects in word processing evoked by semantically related context. Besides the well-known attention-dependent N400 context effect (>250 ms), recent studies demonstrate early automatic context effects in the P1-...
