TL;DR: The essence of the concept emergence is aptly communicated by the following quote, attributed to Aristotle, who lived more than 2000 years ago: The Whole is Greater than the Sum of its Parts.

TL;DR: In this paper, the authors investigated the root cause of interference from photo-voltaic (PV) active infeed converters for static meters in a controlled lab environment and revealed that the meters with the positive deviation used a Rogowski coil current sensor.
Abstract: More often consumers are complaining about the energy bill after the conventional electromechanical meter has been replaced by an electronic, or static, energy meter. Active infeed converters for photo-voltaic systems are a known source for interference to static meters. To investigate the root cause experiments on static meters have been performed in a controlled lab environment. Three-phase meters showed large deviations of more than 250% and −46%. After dismantling it was revealed that the meters with the positive deviation used a Rogowski coil current sensor. The meter with a Hall effect-based current sensor gave the −46% deviation.

TL;DR: A model for inferring the dangerous states of core temperature is proposed and the evaluation results show that the model can to a great extent estimate hazardous situations caused by heat accumulation.
Abstract: One of the numerous applications of wearable computers is providing safety in occupations where heat-related injuries are prevalent. Core temperature, as a parameter that cannot be measured by on-body sensors is a variable that is specifically interesting for realizing such applications. In the context of the design of a sensor-shirt that can be used by firefighters, in this paper we study the importance of different types of sensor measurements and their placement for estimating core temperature. We propose a model for inferring the dangerous states of core temperature. Our evaluation results show that our model can to a great extent estimate hazardous situations caused by heat accumulation.

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: 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: This chapter starts by recalling the MAPE approach in Sect.
Abstract: SoS dynamicity refers to short-term changes in an SoS, which occur in response to changing environmental or operational parameters of the CSs. These changes may have different effects, such as SoS adaptation or the generation of emergent phenomena. This chapter starts by recalling the MAPE approach in Sect. 2 before to introduce existing monitoring approaches in Sect. 3. Finally, Sect. 4 overviews existing reconfiguration techniques for SoS dynamicity management, related to Analyzis, Planning and Execution phases and illustrates through an examples the possible implementations of dynamicity management with modelling and feedback control techniques.
