Small vertebrates were inventoried within three habitat types in a degraded dry forest region of Panama. Animals were classified as frugivorous if they were observed foraging on fruit or if fecal samples contained mostly or exclusively seeds. Overall, we found that eight bat species and 21 bird species consumed fruit. The greatest numbers of birds were observed within live fences and bird speci...

Criminological theories have posited that the built environment impacts where crime occurs; however, measuring is difficult. Furthermore, it uncertain whether differentially in high-disadvantage neighborhoods. This study extracts features of from Google Street View images with a machine learning semantic segmentation strategy to create measures fences, walls, buildings, and greenspace for over ...

We describe a simple, but powerful, program logic for reasoning about C11 relaxed accesses used in conjunction with release and acquire memory fences. Our logic, called fenced separation logic (FSL), extends relaxed separation logic with special modalities for describing state that has to be protected by memory fences. Like its precursor, FSL allows ownership transfer over synchronizations and ...

The effectiveness of a new design of electric strained wire fence (CSL fence) for managing rabbits is currently being assessed in a two year trial. It is being compared with a commercially available electric netting fence (Flexinet fence) and also with farmers' normal control methods. The study is taking place on commercial farms in Cornwall, England, where the fences are being erected to prote...

A common task in automated manufacturing processes is to orient parts prior to assembly. We consider sensorless orientation of a polygonal part by a sequence of fences. We show that any polygonal part can be oriented by a sequence of fences placed along a conveyor belt, thereby settling a conjecture by Wiegley et al. [17], and present the rst polynomial-time algorithm to compute the shortest su...

As a fundamental characteristic of soil physical properties, the soil Particle Size Distribution (PSD) is important in the research on soil moisture migration, solution transformation, and soil erosion. In this research, the PSD characteristics with distinct methods in different land uses are analyzed. The results show that the upper bound of the volume domain of the clay domain ranges from 5.7...

In automated packing or assembly it is often necessary to bring randomly oriented parts into uniform alignment. Mechanical methods such as vibratory bowl feeders are often used for this purpose, although there is no theory for the systematic design of such feeders. A slanted “fence” attached to the stationary sides of a conveyor belt is also capable of orienting a stream of parts and a sequence...
