Earthquakes are one of the natural disasters that pose a major threat to human lives and
property. Earthquake prediction propels the construction and development of modern …

This paper presents a multi-objective location-districting optimization model for sustainable
collection of municipal solid waste, motivated by strategic waste management decisions in …

In this paper, we study the problem of continuous monitoring of reverse k nearest neighbors
queries in Euclidean space as well as in spatial networks. Existing techniques are sensitive …

Nearest neighbour queries (or kNN) have been used in many disciplines, including spatial
databases. kNN queries have gone beyond simply finding nearest objects. It is, therefore …

Abstract The Internet of Things (IoT) has developed rapidly in recent years where significant
numbers of devices have been connected to the network and this will increase over the …

Most models of forest communities cannot represent the asymmetry of crowns resulting from
inter-tree competition. However, this is important for the accurate simulation of mixed and …

Given a set of objects and a query q, a point p is called the reverse k nearest neighbor (R k
NN) of q if q is one of the k closest objects of p. In this paper, we introduce the concept of …

Geographical information systems (GIS) and applications assist us in commuting, traveling
and locating our points of interests. The efficient implementation and support of spatial …

Most IoT systems designed for the implementation of mission-critical systems are multi-
layered. Much of the computing is done in the service and gateway layers. The gateway …

Due to the universality and importance of range search queries processing in mobile and
spatial databases as well as in geographic information system (GIS), numerous approaches …
