JanBogaert PietVanHecke DavidSalvador-VanEysenrode IvanImpens Landscape Fragmentation Assessment Using a Single Measure Wildlife Society Bulletin Allen Press 28 875–881 2000 Measurement of fragmentation is crucial for determining its consequences and to develop policy for nature conservation. We propose a fragmentation measure |φ| which combines, using a multidimensional Euclidean distance, 4 main characteristics of fragmented landscapes: total habitat area, total habitat perimeter, number of patches, and patch isolation. Its properties can be summarized as: 1) |φ| reflects the overall fragmentation status; 2) every component of |φ| is accepted as a measure of fragmentation; 3) every component of |φ| is a normalized variable; 4) every component of |φ| is easy to compute; 5) average patch size, interior habitat, and habitat connectedness are included indirectly in |φ|; 6) |φ| is independent of the land-use type; and 7) |φ| can be calculated for raster and vector data. We show that the normalized values composing |φ| prevent misinterpretation of features as fragment number or boundary length. A sensitivity analysis, based upon artificial patterns, showed that increasing fragmentation is correlated with smaller values of |φ|. Wildlife managers are encouraged to use |φ| for objective evaluation of fragmented landscapes. TaolueChen Jacovan dePol YanjingWang PDL over Accelerated Labeled Transition Systems.

Wireless communication has a limited communication range, which introduces two major problems, currently not captured in distributed middleware. Firstly, they are less reliable and secondly they are extremely dynamic. Both problems complicate the development of mobile software. In this paper we extend the operational semantics of the actor model to capture these two properties by adding a single new concept to the model: the mailbox. This paper provides a foundation for new implementations of the actor language and frameworks that are usable in the context of mobile ad-hoc networks.
