Tropical forests around the world have been lost, mainly because of agricultural activities. Linear elements like riparian vegetation in fragmented tropical landscapes help maintain the native flora and fauna. Information about the role of riparian corridors as a reservoir of bat species, however, is scanty. We assessed the value of riparian corridors on the conservation of phyllostomid bat ass...
Materials and methods: In a descriptive cross-sectional study, 50 schools were selected by random sampling and the illuminance was measured using network method. In each place 2 to 10 measurements (between 8:00 AM and 14:00) were done using Lux meter (TES; A1336). Data was analyzed by GEE in SPSS V. 20. Results: The lighting intensity was measured in 306 places including 194 classrooms, 49 o...
Corridors are commonly used to connect fragments of wildlife habitat, yet the identification of conservation corridors typically neglects processes of habitat selection and movement for target organisms. Instead, corridor designs often are based on binary patterns of habitat suitability. New technologies and analytical tools make it possible to better integrate landscape patterns with behaviora...
Transportation corridor management is regularly performed for evaluation of road conditions, hazards, and planning, and is traditionally based on the manual inspection of the corridors. Recent research projects have evaluated advanced remote sensing technologies, such as LiDAR and photogrammetry, to replace preliminary field evaluations with desktop studies through evaluation of 3d sensor data....
Supply chains are the backbone of trade and commerce. Their logistics use different transport corridors on regular basis for operation al purpose. The international supply chain transport corridors include different infrastructure elements (e.g. weighbridge, package handling equipments, border clearance authorities, and so on). Th is paper presents th e use of multi-agent systems (MAS) to model...
With technology advancement and increasing popularity of location-aware devices, trajectory data are ubiquitous in the real world. Trajectory corridor, as one of the moving patterns, is composed of concatenated sub-trajectory clusters which help analyze the behaviors of moving objects. In this paper we adopt a three-phase approach to discover trajectory corridors using Fréchet distance as a dis...
Conservation scientists emphasize the importance of maintaining a connected network of protected areas to prevent ecosystems and populations from becoming isolated, reduce the risk of extinction, and ultimately sustain biodiversity. Keeping protected areas connected in a network is increasingly recognized as a conservation priority in the current era of rapid climate change. Models that identif...
High-speed intercity passenger rail projects are very complex and require many years of planning and environmental activities before construction can begin. Given the complexity of planning and environmental reviews associated with high-speed intercity passenger rail corridor planning, a systematic approach for high-level screening of various alternative routings for proposed high-speed rail co...
From a mobility perspective, walking is considered to be the most sustainable transport mode. One of the consequences of motor-oriented urban configuration on pedestrian mobility is urban fragmentation, which affects sustainability in cities. In this paper, we use a natural-based approach to landscape fragmentation and connectivity (inherited from landscape ecology) for pedestrian mobility plan...
