Propagation of medium frequency (1-4 MHz) auroral radio waves to the ground via the Z-mode radio window
Recent ground-based observations of auroral radio waves have identified narrowband emissions near 2 and 3 times the lower ionospheric electron cyclotron frequency (fce) known as auroral roars. In this paper the propagation of these waves in the auroral ionosphere is investigated by means of a ray-tracing technique. We model one particular scenario in which a large-scale (tens of kilometers) hor...
متن کاملTowards a worldwide storage infrastructure
Peer-to-peer systems have recently gained a lot of attention in the academic community especially through the design of KBR (Key-Based Routing) algorithms and DHT (Distributed Hash Table)s. On top of these constructs were built promising applications such as video streaming applications but also storage infrastructures benefiting from the availability and resilience of such scalable network pro...
متن کاملRadio Frequency Interference Impact Assessment on Global Navigation Satellite Systems
The Institute for the Protection and Security of the Citizen of the EC Joint Research Centre (IPSC-JRC) has beenmandated to perform a study on the Radio Frequency (RF) threat against telecommunications and ICT controlsystems. This study is divided into two parts. The rst part concerns the assessment of high energy radio frequency(HERF) threats, where the focus is on the generation o...
متن کاملLarge classes of minimally supported frequency wavelets of L 2 ( R ) and H 2 ( R )
We introduce a method to construct large classes of MSF wavelets of the Hardy space H2(R) and symmetric MSF wavelets of L2(R), and discuss the classification of such sets. As application, we show that there are uncountably many wavelet sets of L2(R) and H2(R). We also enumerate all symmetric wavelets of L2(R) with at most three intervals in the positive axis as well as 3-interval wavelet sets o...
متن کاملThe Development of a Dynamic Gis for Maritime Navigation Safety
Maritime safety has a huge impact on the world economy and our everyday lives. The vast majority of world cargo is carried by sea by huge container-carriers. Cargo ships carrying hazardous loads pose serious threats to the environment. The disaster and damage caused in the event of major sea collisions can be difficult and costly to deal with. In our research we took a broad look at the problem...
