This system designs a wireless communication method using GSM to transmit data to the preset of treatment centers whenever an accident occurs. The vehicle is equipped with a GSM and a GPS module. The treatment center process the data received from the GSM module of the vehicle and identifies the location of the vehicle. The GPS module helps in tracking the location and state of the vehicle. Key...

In several applications finding objects closest to a specific location that contains a set of keywords. For example, online yellow pages allows user to specify an address and a set of keywords. In response, the user obtains a list of related information whose description contains these keywords and it’s ordering according to their distance from the specified address. The complexities involved i...

This paper describes a technique to extract geographic location information from a natural language description of a location. The technique relies on a set of domain specific tags and a set of keywords. The tags are used to identify roads, intersections, and landmarks. Tag combinations are used to discover road segments. The technique is applied to understanding highway construction reports fo...

Given a query location and a set of query keywords, a top-k spatial keyword query rank objects based on the distance to the query location and textual relevance to the query keywords. Several solutions have been proposed for top-k spatial keyword queries in Euclidean space. However, few algorithms study top-k keyword queries in undirected road networks where every road segment is undirected. Ev...

This paper proposes a location-aware system for household robots which allows users to paste predefined paper tags at different locations according to users’ comprehension of the house. In this system a household robot may be aware of its location and the attributes thereof by visually recognizing the tags when the robot is moving. This paper also presents a novel user interface to define a mov...

In this survey, we examine an important class of facility location problems known as the multisource Weber problem (also referred to as the continuous location-allocation problem). We also show how recent advances in the use of metaheuristic rules have significantly improved the ability to solve problems of this type. The new solution methods are discussed for both the well known multisource W...

The lightning flash density Ng, so important in Lightning Protection standards for risk assessment calculations, should be replaced by the more suitable lightning strike-point density Nsg. A factor 2 is proposed to relate Ng to Nsg. More precise Ng values should occur from Lightning Location Systems (LLS), while improving their detection efficiency, location accuracy, and classification accurac...
