Dynamic Microclimate Boundaries across a Sharp Tropical Rainforest–Clearing Edge

Microclimate gradients across a forest edge

Despite the importance of forest edges in ecology, only one study has previously been carried out in New Zealand on the modification of climate across forest edges. We measured light exposure, wind speed, air and soil temperature, and vapour pressure deficit (VPD) perpendicular to a north-south aligned, mature, edge of native broadleaf rainforest adjoining grazed pasture. At a point 80 m into t...

Edge Grouping for Detecting Salient Boundaries with Sharp Corners

The Gestalt law of continuity, or smoothness, is an important factor in guiding the edge grouping. In practice, however, the boundaries of many salient structures of interest may not be smooth everywhere and may contain some sharp corners. This paper presents a globally optimal edge-grouping method that can detect perceptually salient boundaries with sharp corners. In this method, a set of stra...

A Method for Microclimate Observation and Thermal Analysis -Tropical Condition of Kuala Lumpur

Using outdoor public spaces as a place of social interaction is in a great consideration these days. Providing tolerable thermal condition as long as possible is one of the primary stage for people’s presence in these places. Outdoor thermal indices are introduced to help architects making appropriate decisions in climate responsive design procedure. By doing some field study research in extr...

Acoustic streaming of a sharp edge.

Anomalous acoustic streaming is observed emanating from sharp edges of solid bodies that are vibrating in fluids. The streaming velocities can be orders of magnitude higher than expected from the Rayleigh streaming at similar amplitudes of vibration. Acoustic velocity of fluid relative to a solid body diverges at a sharp edge, giving rise to a localized time-independent body force acting on the...
