High-Performance cameras are being used in an increasing number of applications. It requires designs that are more and more challenging. In order to validate these camera designs, a reusable automated test setup has been implemented to characterize the static performances of an image acquisition chain. This automated test setup features the characterization of the input referred noise, the integral non linarity (INL), the differential non linearity (DNL), the gain error, the offset error and the total unadjusted error (TUE) of the chain. By collecting samples out of the acquisition chains to build histograms, the static parameters can be computed.
By using samples associated to a DC level applied to the acquisition chain and by computing
the standard deviation of the built histogram, the input referred noise is computed.
Based on coherent sampling condition, a sine signal is applied to the acquisition chain. The collected samples allow to build a sine histogram that can be compared with an ideal sine histogram in order to compute the TUE, the INL, the DNL, the gain and the offset error.
In order to validate the measurement methods, a custom PCB has been designed. The PCB
features the acquisition chains to test, as well as a FPGA and a USB interface to collect data on
an external computer. After having programmed the FPGA to interface with the acquisition chain
and the USB port, samples can be collected. A remote control of the signal sources (DC and sine
generator) has also been implemented using a VISA interface to ease the acquisition and automate the test process.
From the collected samples the static performances of the acquisition chain can be computed.
The computation is done in post processing on a computer. From these computed performances,
the test protocol can be validated. Most of the obtained results are already promising since they
are coherent with the theoretical ones, even if improvements can still be brought to them.

Following the classical work of Norbert Wiener, Ross Ashby, Ludwig von Bertalanffy and many others, the concept of System has been elaborated in different disciplinary fields, allowing interdisciplinary approaches in areas such as Physics, Biology, Chemistry, Cognitive Science, Economics, Engineering, Social Sciences, Mathematics, Medicine, Artificial Intelligence, and Philosophy. The new challenge of Complexity and Emergence has made the concept of System even more relevant to the study of problems with high contextuality. This Special Issue focuses on the nature of new problems arising from the study and modelling of complexity, their eventual common aspects, properties and approaches—already partially considered by different disciplines—as well as focusing on new, possibly unitary, theoretical frameworks. This Special Issue aims to introduce fresh impetus into systems research when the possible detection and correction of mistakes require the development of new knowledge. This book contains contributions presenting new approaches and results, problems and proposals. The context is an interdisciplinary framework dealing, in order, with electronic engineering problems; the problem of the observer; transdisciplinarity; problems of organised complexity; theoretical incompleteness; design of digital systems in a user-centred way; reaction networks as a framework for systems modelling; emergence of a stable system in reaction networks; emergence at the fundamental systems level; behavioural realization of memoryless functions.

When listeners talk about their listening experiences, they often refer to music as if it were a narrative. But can music actually tell a story? Can music be narrative? Traditionally, narrativity is associated with verbal and visual texts, and the mere possibility of musical narrativity is highly debated. In this study, Vincent Meelberg demonstrates that music can indeed be narrative, and that the study of musical narrativity can be very productive. Moreover, Meelberg even makes a stronger claim by contending that contemporary music, too, can be narrative. More specifically, Meelberg suggests considering contemporary musical narratives as metanarratives, i.e. narratives that tell the story of the process of narrativization.
