An Antenna Array for the Galileo System with Beamforming Capabilities
, 2006 Future navigation services provided by the upcoming Galileo satellite system will require corresponding improvements on the navigation receiving systems. The first part of any navigation receiving system is the antenna or antenna terminal.

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...

Integrity Monitoring of Integrated Satellite/Inertial Navigation Systems Using the Likelihood Ratio
, 1996 Global Navigation Satellite Systems (GNSS) have the ability to fulfill the navigation accuracy requirements of most applications. The systems do however lack continuity and integrity to meet the requirements of high precision navigation applications. The

‘Let's talk about the weather’: The activist curriculum and global climate change education
British Educational Research Journal, EarlyView.Abstract Activist movements have garnered significant global attention on a range of sustainability issues, often involving collectives of citizens coming together. Invoked is the idea of citizens informed to act, emerging not from a common‐sense understanding of everyday life, but rather from a deep political understanding of the world—one that is ...

Young people's occupational aspirations beyond the aspiration discourse: A sociocultural perspective
British Educational Research Journal, EarlyView.Abstract Young people's aspirations have been the focus of many educational, sociological and psychological studies. This paper argues, firstly, that the concept of aspirations holds greater generative potential than suggested by the policy‐oriented ‘aspiration discourse’.

Blind Adaptive Beamformer Based on Orthogonal Projections for GNSS
, 2012 The quality of the ranging data provided by a global navigation satellite systems (GNSS) receiver largely depends on the synchronization error, that is, on the accuracy of the propagation time-delay estimation of the line-of-sight (LOS) signal.
