A name or label is an essential and important component of a map. Yet, its placement has always been considered as a most labour-intensive process in manual cartography. In Hong Kong, the process is further complicated by the presence of dual languages (English and Chinese) together. Conversion of 1:1000 analogue map sheets to digital data have been completed but text placement is still perform...

BACKGROUND Epileptogenesis is regarded as a complicated and relatively poorly understood phenomenon. Some of immediate early genes (IEGs) as egr1 (zif268) or arc (arg3.1) are believed to play an important role in the process of epileptogenesis. However, how these genes are engaged in epilepsy is not fully elucidated. METHODS In this study, we sought to explore how the spread of epileptiform a...

We propose a great circle arc detector in a scene represented by an equirectangular image, i.e. a spherical image of the 360 longitude and 180 latitude field of view. Since the straight lines appears curved in equirectangular images, the standard line detection algorithm cannot be used directly in this context. We extend the LSD method (Gioi et al., 2010) to deal with the equirectangular images...

This paper presents a location algorithm for series arc fault in low-voltage indoor power line an AC 230 V 50 Hz home network. At both ends of the line, currents and voltages are recorded each generation at different distances. Previously map trace is created by using stored signature coefficients obtained from Kirchhoff equations which allow virtual decoupling line’s mutual capacitance. Then, ...

The brain's ability to change in response to experience is essential for healthy brain function, and abnormalities in this process contribute to a variety of brain disorders. To better understand the mechanisms by which brain circuits react to an animal's experience requires the ability to monitor the experience-dependent molecular changes in a given set of neurons, over a prolonged period of t...
