This book addresses the experimental calibration of best-estimate
numerical simulation models. The results of measurements and
computations are never exact. Therefore, knowing only the nominal
values of experimentally measured or computed quantities is
insufficient for applications, particularly since the respective
experimental and computed nominal values seldom coincide. In the
author's view, the objective of predictive modeling is to extract
"best estimate" values for model parameters and predicted results,
together with "best estimate" uncertainties for these parameters
and results. To achieve this goal, predictive modeling combines
imprecisely known experimental and computational data, which calls
for reasoning on the basis of incomplete, error-rich, and
occasionally discrepant information. The customary methods used for
data assimilation combine experimental and computational
information by minimizing an a priori, user-chosen, "cost
functional" (usually a quadratic functional that represents the
weighted errors between measured and computed responses). In
contrast to these user-influenced methods, the BERRU (Best Estimate
Results with Reduced Uncertainties) Predictive Modeling methodology
developed by the author relies on the thermodynamics-based maximum
entropy principle to eliminate the need for relying on minimizing
user-chosen functionals, thus generalizing the "data adjustment"
and/or the "4D-VAR" data assimilation procedures used in the
geophysical sciences. The BERRU predictive modeling methodology
also provides a "model validation metric" which quantifies the
consistency (agreement/disagreement) between measurements and
computations. This "model validation metric" (or "consistency
indicator") is constructed from parameter covariance matrices,
response covariance matrices (measured and computed), and response
sensitivities to model parameters. Traditional methods for
computing response sensitivities are hampered by the "curse of
dimensionality," which makes them impractical for applications to
large-scale systems that involve many imprecisely known parameters.
Reducing the computational effort required for precisely
calculating the response sensitivities is paramount, and the
comprehensive adjoint sensitivity analysis methodology developed by
the author shows great promise in this regard, as shown in this
book. After discarding inconsistent data (if any) using the
consistency indicator, the BERRU predictive modeling methodology
provides best-estimate values for predicted parameters and
responses along with best-estimate reduced uncertainties (i.e.,
smaller predicted standard deviations) for the predicted
quantities. Applying the BERRU methodology yields optimal,
experimentally validated, "best estimate" predictive modeling tools
for designing new technologies and facilities, while also improving
on existing ones.

The book focuses on system dependability modeling and calculation,
considering the impact of s-dependency and uncertainty. The best
suited approaches for practical system dependability modeling and
calculation, (1) the minimal cut approach, (2) the Markov process
approach, and (3) the Markov minimal cut approach as a combination
of (1) and (2) are described in detail and applied to several
examples. The stringently used Boolean logic during the whole
development process of the approaches is the key for the
combination of the approaches on a common basis. For large and
complex systems, efficient approximation approaches, e.g. the
probable Markov path approach, have been developed, which can take
into account s-dependencies be-tween components of complex system
structures. A comprehensive analysis of aleatory uncertainty (due
to randomness) and epistemic uncertainty (due to lack of
knowledge), and their combination, developed on the basis of basic
reliability indices and evaluated with the Monte Carlo simulation
method, has been carried out. The uncertainty impact on system
dependability is investigated and discussed using several examples
with different levels of difficulty. The applications cover a wide
variety of large and complex (real-world) systems. Actual
state-of-the-art definitions of terms of the IEC 60050-192:2015
standard, as well as the dependability indices, are used uniformly
in all six chapters of the book.

This book discusses the new roles that the VLSI (very-large-scale
integration of semiconductor circuits) is taking for the safe,
secure, and dependable design and operation of electronic systems.
The book consists of three parts. Part I, as a general introduction
to this vital topic, describes how electronic systems are designed
and tested with particular emphasis on dependability engineering,
where the simultaneous assessment of the detrimental outcome of
failures and cost of their containment is made. This section also
describes the related research project "Dependable VLSI Systems,"
in which the editor and authors of the book were involved for 8
years. Part II addresses various threats to the dependability of
VLSIs as key systems components, including time-dependent
degradations, variations in device characteristics, ionizing
radiation, electromagnetic interference, design errors, and
tampering, with discussion of technologies to counter those
threats. Part III elaborates on the design and test technologies
for dependability in such applications as control of robots and
vehicles, data processing, and storage in a cloud environment and
heterogeneous wireless telecommunications. This book is intended to
be used as a reference for engineers who work on the design and
testing of VLSI systems with particular attention to dependability.
It can be used as a textbook in graduate courses as well. Readers
interested in dependable systems from social and
industrial-economic perspectives will also benefit from the
discussions in this book.
The book summarizes the results of the European research project
"Intelligent fixtures for the manufacturing of low rigidity
components" (INTEFIX). The structure of the book follows the

INTEFIX project deals with the development and analysis of several
exemplary types of intelligent, sensor and actuator integrated
fixtures for the clamping of sensitive workpieces in cutting
machine tools. Thus, the book gives a representative overview about
this innovative field of technology. The demands of the case
studies are described and the technological approaches and
solutions are introduced. Furthermore, innovative methods for the
design and optimization of intelligent fixtures are presented.
