Payload charging events in the mesosphere and their impact on Langmuir type electric probes
(2013)
Three sounding rockets were launched from Andøya Rocket Range in the ECOMA campaign in December 2010. The aim was to study the evolution of meteoric smoke particles during a major meteor shower. Of the various instruments ...
Physical Working Principles of Medical Radar
(2013)
There has been research interest in using radar for contactless measurements of the human heartbeat for several years. While many systems have been demonstrated, not much attention have been given to the actual physical ...
Multi-instrument comparisons of D-region plasma measurements
(2013)
The ECOMA (Existence and Charge state Of Meteoric dust grains in the middle Atmosphere) series of sounding rocket flights consisted of nine flights with almost identical payload design and flight characteristics. All flights ...
Estimating temperature and salinity profiles using empiricalorthogonal functions and clusteringon historical measurements
(2013)
Oceanographic climatology is normally estimated by dividing the world’s oceans into geographical boxes of fixed shape and size, where each box is represented by a climatological salinity and temperature profile. The ...
A model for the viscous dissipation rate in stably stratified, sheared turbulence
(2013)
A model for the turbulence dissipation rate in stably stratified shear turbulence is developed and validated. The functional dependence of the model is derived from first principles and it represents a conceptually new ...
Pixel scaling in infrared focal plane arrays
(2013)
We discuss effects that arise in pixels of IR focal plane arrays (FPAs) when pixel size scales down to approach the wavelength of the incident radiation. To study these effects, we perform first-principles electromagnetic ...
Construction and demonstration of a multispectral tomographic scanning imager (TOSCA)
(2013)
This work presents the first experimental demonstrator of an imager based on a tomographic scanning (TOSCA) principle. The device described generates a stream of multispectral images of a scene or target using simple conical ...

The threat of war and domestic restraints to defence reform- how fear of major military conflict changed and did not change the Ukrainian military 2014-2019
(2019-12-19)
The annexation of Crimea and the Russia enabled rebellion in Donbas created a need for radical improvements of Ukrainian military capability. This study discusses how different, mostly domestic, reform drivers and reform ...
