Hatch Textures for Virtual Endoscopy

We present an illustrative rendering extension for virtual endoscopy to enhance depth perception. For this purpose different hatch textures are applied and their ability to enhance 3D shape estimation is discussed. The stroke directions of the textures are aligned to the principal curvature directions of the surface. Starting with two patterns suggested by Kim et al. [1], we developed texture p...

Tarantula: Killing Driver Bugs Before They Hatch

The Linux operating system is undergoing continual evolution. Evolution in the kernel and generic driver modules often triggers the need for corresponding evolutions in specific device drivers. Such collateral evolutions are tedious, because of the large number of device drivers, and error-prone, because of the complexity of the code modifications involved. We propose an automatic tool, Tarantu...

Performance Analysis of Position-Domain Hatch Filter

Motivated both by the efficiency of the Hatch gain compared to the Kalman-type gain and the advantage of position-domain filtering compared to range-domain filtering, this paper proposes a position-domain Hatch filter for differential kinematic satellite-based positioning. A theoretically rigorous proof is provided to show that the Hatch gain generates a white residual sequence and is more effi...

Glassfrog embryos hatch early after parental desertion.

Both parental care and hatching plasticity can improve embryo survival. Research has found that parents can alter hatching time owing to a direct effect of care on embryogenesis or via forms of care that cue the hatching process. Because parental care alters conditions critical for offspring development, hatching plasticity could allow embryos to exploit variation in parental behaviour. However...
