Research ArticleOpen accessIn the abstractThe Importance of Maintaining a Proper Database on Forest Restoration Program for Orangutans in BorneoRaymond Alfred, Koh Pei Hue, Lee Shan Khee, Rayner AlfredProblem statement: The lowland forest of Sabah is the most important habitat for orangutans and pygmy elephants. This is shown in the WWF-Malaysia’s elephant tracking programme in which satellite-based Global Position System (GPS) collar devices are used to monitor their movement and the range of their habitats, as well as an aerial survey on orangutan’s nest is performed to determine … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,910 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA New Approach in Individual Tree Counting of Nyatoh (Palaquium spp.) Using an Airborne SpectroradiometerKamaruzaman JusoffProblem statement: In Malaysia inadequate data are available to make decisions regarding the sustainable management of Nyatoh (Palaquium spp.). Factual data and estimation of Nyatoh in the lowland dipterocarp forest resources are still lacking or, if available, are not complete, reliable or up to date. The collection and compilation of information and updating of existing data in near real time … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,955 accessesView PDF Cite

OluseyeProblem statement: The natural radioactivity levels in the soils of Ogun-Osun River Basins Development Authority Headquarters, (O-ORBDA HQ) Abeokuta, South-Western part of Nigeria were measured. Approach: (O-ORBDA HQ) is a parastatal of Federal Ministry of Water Resources and Rural Development in Nigeria charged with the responsibility for the development and management of the water resources in its area of coverage. … …Physics International, Vol. 1, Issue 1 · 30 Mar 2010 · 7,917 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPredict Location(s) of Apis dorsata Nesting Sites Using Remote Sensing and Geographic Information System in Melaleuca ForestiM. M. Saberioon, M. Mardan, L. Nordin et al.Problem statement: The Asiatic Giant honeybees (Apis dorsata) are seasonally abounded throughout the upland and lowland rainforests in South East Asia. The colonies of A. dorsata are found to nest in aggregates on tall bee trees (tree emergent) in the open, as well as, nesting singly in concealed locations when nesting low, especially in the submerged forest of Melaleuca cajuputi … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 8,603 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSoil Degradation Risk Prediction Integrating RUSLE with Geo-information Techniques, the Case of Northern Shaanxi Province in ChinaMushtak T. Jabbar, Xiaoling ChenThis research integrated the Revised Universal Soil Loss Equation (RUSLE) with RS, GIS and GPS techniques to quantify soil erosion risk and the northern part of Shaanxi province in China was taken as a case. A system was established for rating soil erodibility, slope length/gradient, rainfall erosivity and conservation practices. The rating values served as inputs into a modified Revised … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,050 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Qualitative Assessment of VANET Routing Protocols Under Different Mobility ModelsMeriem Houmer, Moulay Lahcen HasnaouiVehicular Ad-hoc Networks (VANET) is an advanced wireless network that came to increase traffic safety, efficiency and to improve driving experience. The high mobility of nodes is the major characteristic in these networks. The aim of this paper is to figure out the impact of various mobility models on the performance of Ad-hoc On-demand Distance Vector (AODV), Cluster-Based Directional Routing … …Journal of Computer Science, Vol. 15, Issue 1 · 23 Jan 2019 · 7,458 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProximity Aware Routing in Ad Hoc NetworksValerie Alandzi, Alejandro QuinteroMost of the existing routing protocols for ad hoc networks are designed to scale in networks of a few hundred nodes. They rely on state concerning all links of the network or links on the route between a source and a destination. This may result in poor scaling properties in larger mobile networks or when node mobility is high. Using … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,733 accessesView PDF Cite
