This study investigated the impacts of playing in a natural environment on motor development in children. Methods from landscape ecology were applied for landscape analysis and entered into a Geographic Information System (GIS). Localization of play habitats was done by use of Global Positioning Systems (GPS). A quasi-experimental study was conducted on five-, six-, and seven-year old children ...

FirstAED is a supplement to the existing emergency response systems. The aim is to shorten the community first responder response times at emergency calls to below five minutes in a bridge connected island area. FirstAED defines a way to dispatch the nearby three first responders and organise their roles in a team structure to reduce response times, ensure citizens’ safety and offer equal possi...

The concept of using the steering angle sensor to enhance positioning accuracy during Global Positioning System (GPS) outages is the focus of this article. This development of a GPS Micro-Electro-Mechanical Systems Inertial Measurement Unit (MEMS IMU) steering angle sensor vehicular positioning system is discussed in detail including the error dynamics and measurement models as well as integrat...

The fabrication of accurate prototype from CAD model directly in short time depends on the accurate tracking control and reference trajectory planning in (Laminated Object Manufacture) LOM application. An improvement on contour accuracy is acquired by the introduction of a tracking controller and a trajectory generation policy. A model of the X-Y positioning system of LOM machine is developed a...

New devices that can connect to the Web continue to appear regularly. Most of these devices can be used while the user is mobile. Newer devices often have more advanced capabilities than the more traditional computer systems that are commonly used for Web access. For example, a significant number of new devices now have built-in support for the Global Positioning System [1] for determining thei...

Pedestrian navigation especially indoors suffers from the unavailability of useful GNSS signals for positioning. Alternatively, a low-cost Inertial Measurement Unit (IMU) positioning system that does not depend on the GNSS signal can be used for indoor navigation. However its performance is still compromised because of the fastaccumulating heading drift error affecting such a low-cost IMU senso...

This paper describes the undergraduate radar course taught at the Escola Universitària Politècnica del Baix Llobregat (EUPBL) of the Universitat Politècnica de Catalunya (UPC), Barcelona, Spain. At present, the EUPBL offers a three-year degree in Technical Telecommunications Engineering. This paper briefly describes the EUPBL, the organization of the degree program, the structure of the radar c...

Today, there are two Global Navigation Satellite Systems (GNSS) that are fully operational and commercially available to provide all-weather guidance virtually 24 h a day anywhere on the surface of the earth. GNSS are the collection of localization systems that use satellites to know the location of a user receiver in a global (Earth-centered) coordinate system and this has become the positioni...
