TL;DR: The changes in the standards and activities performed by the E3AT and Expert Group 7 are described, which include the replacement of national standards with international standards published by the NATO (North Atlantic Treaty Organization) series.
Abstract: In 2009 the European Directive on Defence Procurement was published, and was transferred into national law in most European Union countries in the last few years. This Directive (and national Laws) gives a clear preference for international (defence equipment) standards: National standards shall not be used in contracts anymore. The objective of the European Commission is to support one European-wide defence equipment market, and national standards are preventing such a European-wide level-playing field. The European Defence STAndards Reference (EDSTAR) system which is being maintained by the European Defence Agency (EDA) is thus referring to the STANAG 4370, which is referring to the AECTP 250 and AECTP 500 series, published by the NATO (North Atlantic Treaty Organization). A new version of these standards is published in 2014 (AECTP 250) and 2016 (AECTP 500). Some parts of the AECTP, notably the AECTP 507, needed major upgrades before national standards could be replaced by the AECTP. This activity has been performed by the Electromagnetic Environmental Effects (E3) Action Team of NATO, and maintenance of the E3 standards is performed by Expert Group 7, on E3, of EDSTAR. This paper describes the changes in the standards and activities performed by the E3AT and Expert Group 7.

TL;DR: In this paper, the concept of preloading the bearing system has been evaluated using many experiments on stationary and rotating bearings, and after performing endurance testing, it was shown that if the bearing is sufficiently preloaded it is still providing a conductive path via boundary lubrication.
Abstract: When a radar system onboard a ship is struck by lightning the current has to be conducted via defined paths to prevent damage. A key element to protect is the bearing system between the rotating and stationary part. The conventional way of protecting bearing is to provide a bypass current path via additional measures such as a slip ring. The main cause of damage to the bearing system is the arcing due to high voltage difference between rollers and raceway. It is commonly assumed that, if the radar is rotating, the lubrication between the rolling elements and the raceway is a non-electrical conducting hydrodynamic lubrication layer, and high voltages can be developed. But if the bearing is sufficiently preloaded it is still providing a conductive path via boundary lubrication. No arcing occurs, and no damage. The concept of pre-loading the bearing system has been evaluated using many experiments on stationary and rotating bearings, and after performing endurance testing.

TL;DR: It is shown that the EN 50561-3 and the power line communication systems are violating the essential requirements of the European EMC Directive.
Abstract: The EN 50561-3, a power line communication standard, has been published. It allows very high interference levels, and is neglecting the allocation of the very high frequency band 30 MHz–87.5 MHz, which is mainly assigned to military communication. It is shown that these communication systems are severely degraded, in our experiment a reduction of performance of 44 dB was measured. The military personal who are, especially after recent terrorist attacks and the following lockdowns, active in our cities to safeguard the citizens are dependant of the use of the very high frequency communication systems, and they will be very seriously hampered when using then communication systems. It is shown that the EN 50561-3 and the power line communication systems are violating the essential requirements of the European EMC Directive.

TL;DR: A narrative game engine and accompanying authoring tool that allows for easy development of game scenarios, including in-game and summative feedback in terms of key performance indicators and decision-making styles is focused on.
Abstract: In this paper we will focus on a narrative game engine and accompanying authoring tool that allows for easy development of game scenarios, including in-game and summative feedback in terms of key performance indicators and decision-making styles. Using our model driven game engine, we co-developed numerous games together with several modelling and simulation experts from various domains. The resulting single player turn-taking games are offered as a game service via on-line accessible learning management systems, and currently used in a variety of leadership training programs making trainees aware of their natural decision-making behaviors.
