In October, 2016 China Great Wall Industry Corporation and Spacestar Technology Company Ltd of China entered into cooperative agreement with Nigerian Communications Satellite Ltd on a Satellite-Based Augmentation System (SBAS) performance test and assessment of the Nigerian Communications Satellite (NIGCOMSAT-1R) augmentation System exploiting NIGCOMSAT-1R L Band. This paper examines test bed experimentation conducted in conjunction with partners to validate functional requirements, performance ...

AbstractSeveral recent studies assert that in complex systems, mishaps often result from non-linear interactions between very normal behaviours. These interactions gradually shift the system to a p...

A full-reference image quality assessment (FR-IQA) method for multi-distortion based on visual mutual information (MD-IQA) is proposed to solve the problem that the existing FR-IQA methods are mostly applicable to single-distorted images, but the assessment result for multiply distorted images is not ideal. First, the reference image and the distorted image are preprocessed by steerable pyramid decomposition and contrast sensitivity function (CSF). Next, a Gaussian scale mixture (GSM) model and ...

The market for electric vehicles is growing day by day and electric car chargers can be seen often on pavements of the major cities and towns. With this growing market, industry is already looking for another breakthrough, i.e. wireless vehicle charging. This is much like charging smart phones using wireless charging pads instead of plugging the vehicle in. Industry is exploring ways to charge Electric vehicles wirelessly when the car is parked over a charger on the ground beneath it. For the wi...

A spatial domain optimal trade-off Maximum Average Correlation Height (SPOT-MACH) filter has been shown to have advantages over frequency domain implementations of the Optimal Trade-Off Maximum Average Correlation Height (OR-MACH) filter as it can be made locally adaptive to spatial variations in the input image background clutter and normalized for local intensity changes. This enables the spatial domain implementation to be resistant to illumination changes. The Affine Scale Invariant Feature ...

Smartphone has become a necessary adjunct to people’s daily life. Mobile apps such as instant messaging and payment wallet are commonly used on smartphones. In China, WeChat is the most popular social application due to its multipurpose platform such as online advertisements and payments, etc. WeChat is expected to become more popular since it has just been launched in Europe in 2017. The purpose of this study is to evaluate psychological motivations that can affect WeChat users’ intention to re...

The importance and application of global navigation satellite systems (GNSS) has never been greater; there is increasing demand for both commercial and government projects; indeed, owning and operating a GNSS facility has become a matter of national esteem. This article reviews some of the history that led up to the USA building its benchmark Global Positioning System (GPS) exploiting electromagnetic waves and reviews the progress being made by other nations in constructing accurate navigation p...

Scientists, investors and policy makers have become aware of the importance of providing near accurate spatial estimates of renewable energies. This is why current studies show improvements in methodologies to provide more precise energy predictions. Wind energy is tied to weather patterns, which are irregular, especially in climates with erratic weather patterns. This can lead to errors in the predicted potentials. Therefore, recurrent neural networks (RNN) are exploited for enhanced wind-farm ...

United Kingdom’s Brexit from the European Union implies restricted access to the European Global Navigation Satellite System (GNSS) System - Galileo; with no access to the secured and encrypted signal used for defense and government purposes, which is restricted to European Union (EU) members. To mitigate this issue, the United Kingdom can, as a matter of urgency, launch a payload on a national military Communications Satellite to provide Navigation Overlay Services for the United Kingdom territ...
