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.

Due to the intensive development of the global economy, many problems are constantly emerging connected to the safety of ships’ motion in the context of increasing marine traffic. These problems seem to be especially significant for the further development of marine transportation services, with the need to considerably increase their efficiency and reliability. One of the most commonly used approaches to ensuring safety and efficiency is the wide implementation of various automated systems for guidance and control, including such popular systems as marine autopilots, dynamic positioning systems, speed control systems, automatic routing installations, etc. This Special Issue focuses on various problems related to the analysis, design, modelling, and operation of the aforementioned systems. It covers such actual problems as tracking control, path following control, ship weather routing, course keeping control, control of autonomous underwater vehicles, ship collision avoidance. These problems are investigated using methods such as neural networks, sliding mode control, genetic algorithms, L2-gain approach, optimal damping concept, fuzzy logic and others. This Special Issue is intended to present and discuss significant contemporary problems in the areas of automatic control and the routing of marine vessels.

The inability of forecasters to predict accurately the 1990-1991 recession emphasizes the need for better ways for charting the course of the economy. In this volume, leading economists examine forecasting techniques developed over the past ten years, compare their performance to traditional econometric models, and discuss new methods for forecasting and time series analysis.
