The establishment of corridors can offset the negative effects of habitat fragmentation by connecting isolated habitat patches. However, the practical value of corridor planning is minimal if corridor identification is not based on reliable quantitative information about species-environment relationships. An example of this need for quantitative information is planning for giant panda conservat...

Abstract Fragmentation impacts disconnecting protected areas in Gunungkidul Regency, namely Bunder Forest Park (BFP) and the Paliyan Wildlife Reserve (PWR). This also decreases carrying capacity PWR, degrading Long-Tailed Macaque (LTM) habitat. Therefore, this research aims to analyze landscape structure between Protected areas, habitat suitability of LTM determine connectivity potential as an ...

At lunchtime it’s crucial for people to get to the food trucks as quickly as possible. The building is represented by a graph G = (V,E) where each room, landing, or other location is represented by a vertex and each corridor or stairway is represented by an edge. Each corridor has associated capacity c, meaning that at most c people can pass through the corridor at once. Traversing a corridor f...

Runoff is an important component of water resources and also the basis for regional development utilization. In order to explore new characteristics spatiotemporal variation runoff in whole Yellow River Basin, Basin from 1982 2012 was studied based on measured data 14 representative basins upper, middle, lower reaches Basin. The results showed that depth a decreasing trend, with decrease rate 0...

Abstract The critical step in increasing water availability and land productivity areas with freshwater scarcity, such as arid semi-arid, is identifying suitable sites for Rain Water Harvesting (RWH). Identifying RWH site-specific due to a wide variety of region’s characteristics. Biophysical (slope, soil texture, drainage density, use), hydrological (runoff potential), socio-economic (distance...

Wireless sensor networks are expected to play an essential role as a social infrastructure to realize our safe and secure living environment. In such a network, critical information must be transmitted faster and more reliably than other information. We propose a distributed transmission mechanism which enables emergency packets to be carried with high reliability and low latency along a prefer...

A k-dense corridor through a finite set, S, of n points in the plane is the open region of the plane that is bounded by two parallel lines that intersect the convex hull of S and such that the region contains k points of S. The problem of finding a widest k-dense corridor arises in robot motion-planning. In this paper, efficient solutions are presented for several versions of this problem. Resu...
