In-Orbit Aerodynamic Coefficient Measurements using SOAR (Satellite for Orbital Aerodynamics Research)
N. H. Crisp, P. C. E. Roberts, S. Livadiotti +26
The Satellite for Orbital Aerodynamics Research (SOAR) is a CubeSat mission, due to be launched in 2021, to investigate the interaction between different materials and the atmosphe…
The Future is Big Graphs! A Community View on Graph Processing Systems
Sherif Sakr, Angela Bonifati, Hannes Voigt +38
Graphs are by nature unifying abstractions that can leverage interconnectedness to represent, explore, predict, and explain real- and digital-world phenomena. Although real users a…
Estimating Conditional Transfer Entropy in Time Series using Mutual Information and Non-linear Prediction
Payam Shahsavari Baboukani, Carina Graversen, Emina Alickovic +1
We propose a new estimator to measure directed dependencies in time series. The dimensionality of data is first reduced using a new non-uniform embedding technique, where the varia…
A Review of Gas-Surface Interaction Models for Orbital Aerodynamics Applications
Sabrina Livadiotti, Nicholas H. Crisp, Peter C. E. Roberts +29
Renewed interest in Very Low Earth Orbits (VLEO) - i.e. altitudes below 450 km - has led to an increased demand for accurate environment characterisation and aerodynamic force pred…
FDD Massive MIMO -- Antenna Duplex Pattern an-Reciprocity : A Missing Brick
Patrick C. F. Eggers, Stanislav S. Zhekov
Obtaining down link (DL) channel state information (CSI) at the base station (BS) is challenging for frequencydivision-duplex (FDD) massive MIMO (MM) systems. Considerable overhead…
5G satellite networks for IoT: offloading and backhauling
Beatriz Soret, Israel Leyva-Mayorga, Stefano Cioni +1
One of the main drivers of 5G cellular networks is provision of connectivity service for various Internet of Things (IoT) devices. Considering the potential volume of IoT devices a…
