Revealing prospective locations of hydrothermal alteration zones (HAZs) is an important technique for mineral prospecting. In this study, we used multiple criteria inferred from Landsat-8 OLI, Sentinel-2, and ASTER data using a GIS-based weighted overlay multi-criteria decision analysis approach to build model the delineating deposits in Khnaiguiyah district, Saudi Arabia. The utilized algorith...

Berdasarkan kondisi geografis Kecamatan Nusaniwe yang merupakan kawasan rawan tsunami, dengan pertumbuhan penduduk semakin berkembang, hal ini dapat meningkatkan risiko tsunami sebagai bencana sulit diprediksi kedatangannya. Penelitian bertujuan untuk menganalisis dinamika spasial wilayah di Nusaniwe. menggunakan data tutupan lahan multi temporal, driving factor perkembangan terbangun, jarak da...

The research community has turned to create Semantic Overlay Networks for information retrieval in large scale peer-to-peer networks. Much research work in semantic overlay protocols and searching algorithms is done and their results indicate that semantic overlay is powerful for content searching in peer-to-peer network. However, very limited work has been done in analyzing and evaluating char...

Overlay routing is an application-level routing mechanism on overlay networks. Previous researches have revealed that the overlay routing can improve user-perceived performance. However, it may also generate traffic unintended by ISPs, incurring additional monetary cost. In addition, since ISPs and end users have their own objectives respectively regarding traffic routing, overlay routing must ...

Minimizing the outage probability and maximizing throughput are two important aspects in device to device (D2D) communications, which are greatly related to each other. In this paper, first, the exact formulas of the outage probability for D2D communications underlaying or overlaying cellular network are derived which jointly experience Additive White Gaussian Noise (AWGN) and Rayleigh multipat...

site selection is an important and necessary issue for waste management in fast-growing regions. because of the complexity of waste management systems, the selection of the appropriate solid waste landfill site requires consideration of multiple alternative solutions and evaluation criteria. this paper addresses the sitting of a new landfill using a multi-criteria decision analysis (mcda) and o...

Recently, application-layer multicast has emerged as an attempt to support group applications without the need for a network-layer multicast protocol, such as IP multicast. In application-layer multicast, applications arrange themselves as a logical overlay network and transfer data within the overlay network. In this paper, Delaunay triangulations are investigated as an overlay network topolog...

The Internet is a complex structure arising from the interconnection of numerous autonomous systems (AS), each exercising its own administrative policies to reflect the commercial agreements behind the interconnection. However, routing in service overlay networks is quite capable of violating these policies to its advantage. To prevent these violations, we see an impending drive in the current ...

Urban ecological vulnerability is measured on the basis of ecological sensitivity and resilience based on the concept analysis of vulnerability. GIS-based multicriteria decision analysis (GIS-MCDA) methods are used, supported by the spatial analysis tools of GIS, to define different levels of vulnerability for areas of the urban ecology. These areas are further classified into different types o...

the public class parking as an essential component of a modern transport system within the city, provided spaces for the removal of stationary traffic in urban communication system, spaces to temporarily stop vehicles and thus the flow of traffic. locate the appropriate class parking using technological methods, particularly in metropolitan, maximum and optimum use of urban space, so improved p...
