This article formulated, simulated and evaluated an enhanced model for a non-linear/non-Gaussian integrated Global Positioning System (GPS) and Inertial Navigation System (INS) mobile-based device navigation system using the Particle Filter (PF). This was with a view to enhancing the accuracy...

Global navigation satellite systems (GNSS) have been widely used in many applications where positioning plays an important role. However, the performances of these applications can be degraded in urban canyons, due to Non-Line-Of-Sight (NLOS) and Multipath interference affecting GNSS signals. In...

A fast inter-prediction algorithm based on matching block features is proposed in this article. The position of the matching block of the current CU in the previous frame is found by the motion vector estimated by the corresponding located CU in the previous frame. Then, a weighted motion vector...

This article describes how understanding the potential characteristics of video services is very important, as it can help users or third-party applications to predict performance or to identify service strategies. For this purpose, a measurement system deployed in 11 provinces and cities in...

Mobile applications show great potential for the assessment and registration of information regarding headaches. However, data on the content and usability of mobile applications for headache that are accessible to the public in European Portuguese are scarce, as well the criterion validity....

In the past, banking took place only inside bank rooms, which was a task for customers and bankers at the same time. But in our day, thanks to the high-speed development and growth of mobile technology, the mobile phone platform had the power to create great opportunities for customers of the...

In sub-Saharan Africa, studies show that the key driver for mobile Internet use is social media. However, despite the global reach and proliferation of the Internet and mobile phones, research on mobile Internet use in rural communities in Sub-Saharan Africa is lacking. There is very little...

Brand perceptual mapping is a visual technique, it displays how a brand is positioned in the mind of customers, as well as in relation to the competitors. With the rapid growth of e-commerce and the abundance of online consumer-generated content, there is no need for marketers to go through...

Opportunistic communication in MANET's reduce resource starvation and enhances the stability of a network by decreasing high routing overhead. But the frequent opportunistic contact among the devices is prone to security threats. This article proposes a novel cognitive opportunistic...
