Obviously navigation is one of the most complicated issues in mobile robots. Intelligent algorithms are often used for error handling in robot navigation. This Paper deals with the problem of Inertial Measurement Unit (IMU) error handling by using Extended Kalman Filter (EKF) as an Expert Algorithms. Our focus is put on the field of mobile robot navigation in the 2D environments. The main chall...

Today information systems play key role in new century, geographical information system (GIS) as a special class of information system. Now we are moving wired to wireless network, that is mobile environment shown in fig2 (any where any time and any thing computing), plays key role in this new century. In this application mobile GIS, which will be a network environment, is proposed, which can p...

This paper presents an assistive system for the visually impaired and blind people which helps them using public transport means. The proposed system uses mobile phones as a medium for passenger information system and GPS (Global Positioning System), GSM (Global System for Mobile Communications) and Bluetooth technologies for location and communication purposes. In the proposed system sound mes...

In recent years, cell phones have played an increasingly important role in rapidly-developing global telecommunication services. At present, mobile business develops very fast. However, the development in other mobile service fields, such as public service, mobile medical service, etc, is still in its infant stage. Drawing on the experience of the ‘doctor workstation project’ which is cooperate...

Background: Mobile health is one of the new technologies for the utilization of health information. For its successful implementation as well as any other system, we must primarily measure the adoption and use of its factors. The purpose of this study was to systematically investigate published articles about the factors affecting the adoption of mobile health and categorizing the factors affec...

Mobile telephone systems are undergoing a substantial change from voice based systems which also support data transfer to become systems which truly support packet switched data services to mobile subscribers. This evolution towards the third generation (3G) mobile system will be based on the Global System for Mobile communications (GSM) [1] and will begin with the General Packet Radio Service ...
