Signals of Opportunity in Low Earth Orbit

open access: yes, 2018
The goal of this dissertation is to perform a preliminary study concerning availability requirements for successful navigation in orbit. A number of signal types will then be studied in order to verify requirement satisfaction, also to assess the feasibility of using signals of opportunity such as DTTV and LTE existent at Low Earth Orbit altitudes.

Using a ‘wellbeing’ cost-effectiveness approach to improve resource allocation in social care [PDF]

open access: yes, 2015
The promotion of wellbeing is the newly-stated guiding principle for the long-term care (social care) system in England. It signals a shift away from a focus on care need ‘deficits’ approach.

Bistatic SAR Imaging and Precise Orbit Determination Using Geostationary Telecommunication Satellites

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
SAR satellite missions from geostationary orbits (GEOSAR) would offer the short revisit times required in the observation of fast phenomena. Ground-based multiple baseline interferometry is a technique under study for precise orbit determination of GEO ...

The benefits of cost system accuracy in a competitive price setting duopoly. [PDF]

open access: yes
This study reports the results of an experiment to investigate the value of increased cost report accuracy in competitive pricing decisions. Prior work has shown that in more competitive environments, cost system choice matters less since there is ...
