TWITTER, a popular microblogging service, an important characteristic of Twitter is its real-time nature. We analyze the real-time interaction of events such as earthquakes in Twitter and propose an algorithm to monitor tweets and to detect a target event. To detect a target event, we devise a classifier of tweets based on features such as the keywords in a tweet, the number of words, and their...

A maxbias curve is a powerful tool to describe the robustness of an estimator. It tells us how much an estimator can change due to a given fraction of contamination. In this paper, maxbias curves are computed for some univariate location estimators based on subranges: midranges, trimmed means and the univariate Minimum Volume Ellipsoid (MVE) location estimators. These estimators are intuitively...

In this work we consider the maximum p-facility location problem with k additional resource constraints. We prove that the simple greedy algorithm has performance guarantee (1 − e−(k+1))/(k + 1). In the case k = 0 our performance guarantee coincides with bound due to Nemhauser, Wolsey and Fisher [4]. keywords: approximation algorithm, facility location, submodular functions.

In this work, an approach focused on locating and recommending health care centers within a certain range of distance is presented. The proposed approach includes several integration technologies such as location services, mobile devices, social networks, ontologies, and historical statistics about vehicular traffic. KeywoRDS Collaborative Recommender System, Health Services, Location Technique...

This paper presents background theories and required steps towards preparation of a WLAN location system. This paper targets on a software project and intention behind this paper is to motivate the young researchers in the area. Keywords-component; WLAN; Location Systems; K-nearest

Through the course of this paper we define Locationbased Intelligence (LBI) which is outgrowing from process of amalgamation of geolocation and Business Intelligence. Amalgamating geolocation with traditional Business Intelligence (BI) results in a new dimension of BI named Location-based Intelligence. LBI is defined as leveraging unified location information for business intelligence. Collecti...

The mobile nodes in MANETs dynamically change their topology and hence require an efficient mechanism to communicate with each other. There are number of routing protocols anticipated for MANET environment categorized as Location based routing protocols and Non-Location based routing protocols. In MANETs, Location based routing protocols are preferred as they are more efficient in routing compa...

Geofence is a virtual fence defined by a preset physical radius around a target location. Geofencing App provides location-based services which define the actionable operations upon the crossing of a geofence. Geofencing requires continual location tracking, which can consume noticeable amount of battery power. Additionally, location updates need to be frequent and accurate or order so that act...
