text: Unter welchen historischen Bedingungen und mit welchen Auswirkungen wurde
der Computer zum Bestandteil des Wohnalltags? Und wie verhält es sich dabei mit
Praktiken des Wohnens und Wohnungseinrichtens? Die Beiträger*innen werfen einen
Blick auf die Computerisierung des Zuhauses und zeigen, wie sie sich vollzieht.
Der Fokus ihrer Analysen liegt einerseits darauf, wie Arbeit und Assistenz das
Wohnen im Hinblick auf den Computer prägen. Andererseits denken sie den Computer
aus der Perspektive der Wohnumgebungen neu und geben so einen kompakten medienhistorischen
Überblick über den Beginn des Smart Homes.

text: Within this work, we investigate how data-driven numerical approximation methods
of the Koopman operator can be used in practical control engineering applications.
We refer to the method Extended Dynamic Mode Decomposition (EDMD), which approximates
a nonlinear dynamical system as a linear model. This makes the method ideal for
control engineering applications, because a linear system description is often
assumed for this purpose. Using academic examples, we simulatively analyze the
prediction performance of the learned EDMD models and show how relevant system
properties like stability, controllability, and observability are reflected by
the EDMD model, which is a critical requirement for a successful control design
process. Subsequently, we present our experimental results on a mechatronic test
bench and evaluate the applicability to the control engineering design process.
As a result, the investigated methods are suitable as a low-effort alternative
for the design steps of model building and adaptation in the classical model-based
controller design method.

text: LLC resonant converters are typically unsuitable to be applied for wide voltage-transfer
ratio applications. With a full-bridge inverter, however, they can be operated
in a variety of different modulations. Most notably, by permanently turning on
one MOSFET and turning off the other MOSFET of the same bridge leg, the LLC can
be operated in half-bridge configuration reducing the gain by a factor of two.
The resonant capacitor is hereby charged to an average voltage of half the input
voltage. In this modulation, however, the switch that is permanently turned on
is stressed by the complete resonant current while exhibiting no switching losses.
This paper proves that the frequency-doubler modulation can better balance the
losses among all MOSFETs and should be the preferred mode of operation favored
over the conventional half-bridge modulation. This paper analyzes the beneficial
loss distribution, proposes an on-the-fly morphing modulation and discusses potential
operating strategies to further reduce the junction temperature. Furthermore,
it is shown that this modulation can also be altered to achieve the asymmetrical
LLC operation. Experimental measurement results show that the modulation results
in a substantial decrease of the maximum MOSFET temperature and shows that the
converter can be smoothly transitioned during operation from full-bridge modulation
to the frequency-doubler half-bridge operation and back.

text: 'Piezoelectric inertia motors, also known as ``stick--slip drives'''', use
the inertia of a body to drive it in small steps by means of a friction contact.
While these steps are classically assumed to involve stiction and sliding, the
motors can also operate in ``slip--slip'''' mode without any phase of static friction.
This contribution provides a systematic investigation and performance comparison
of different stick--slip and slip--slip modes of operation. Different criteria
for comparing the motional performance of inertia motors are defined: Steady state
velocity, smoothness of motion, and start-up time. Using the example of a translational
inertia motor excited by an ideal displacement signal, it is found that the maximum
velocity reachable in stick--slip operation is limited principally, while continuous
slip--slip operation allows very high velocities. For the investigated driving
signals, the motor velocity is proportional to the square root of the actuator
stroke. The motor performance with these ideal signals defines an upper boundary
for the performance of real motors.'

text: Piezoelectric inertia motors use the inertia of a body to drive it by means
of a friction contact in a series of small steps. These motors can operate in
``stick-slip'' or ``slip-slip'' mode, with the fundamental frequency of the driving
signal ranging from several Hertz to more than 100 kHz. To predict the motor characteristics,
a Coulomb friction model is sufficient in many cases, but numerical simulation
requires microscopic time steps. This contribution proposes a much faster simulation
technique using one evaluation per period of the excitation signal. The proposed
technique produces results very close to those of timestep simulation for ultrasonics
inertia motors and allows direct determination of the steady-state velocity of
an inertia motor from the motion profile of the driving part. Thus it is a useful
simulation technique which can be applied in both analysis and design of inertia
motors, especially for parameter studies and optimisation.

text: Self-optimizing systems are able to adapt their behavior autonomously according
to their current self-determined objectives. Unforeseen influences could lead
to dependability-critical behavior of the system. Methods are required which secure
self-optimizing systems during operation. These methods to increase the dependability
of the system should already be taken into consideration in the design process.
This paper presents a guideline for the dependability-oriented design of self-optimizing
systems, which integrates established classical methods like failure mode and
effects analysis as well as methods based on self-optimization. On the one hand
self-optimization is used to increase the dependability of the system by integrating
objectives like safety, availability, and reliability to the objectives of the
system. On the other hand methods are required to ensure the self-optimization
itself. As basis for this guideline serves the principle solution of the system.
The six phases of the guideline extend the design process and lead to an enhanced
principle solution. Additionally, the guideline illustrates phases to implement
and validate the self-optimizing system. The proposed guideline is applied to
an innovative rail-bound vehicle, called RailCab, which is equipped with self-optimizing
function modules.

text: In this article, we present a flexible simulation environment for embedded
real-time software refinement by a mixed level cosimulation. For this, we combine
the native speed of an abstract real-time operating system (RTOS) model in SystemC
with dynamic binary translation for fast Instruction Set Simulation (ISS) by QEMU.
In order to support stepwise RTOS software refinement from system level to the
target software, each task can be separately migrated between the native execution
and the ISS. By adapting the dynamic binary translation approach to an efficient
but yet very accurate synchronization scheme the overhead of QEMU user mode execution
is only factor two compared to native SystemC. Furthermore, the simulation speed
increases almost linearly according to the utilization of the task set abstracted
by the native execution. Hereby, the simulation time can be considerably reduced
by cosimulating just a subset of tasks on QEMU.

text: In this paper, parameter estimation of a state-space model of noise or noisy
speech cepstra is investigated. A blockwise EM algorithm is derived for the estimation
of the state and observation noise covariance from noise-only input data. It is
supposed to be used during the offline training mode of a speech recognizer. Further
a sequential online EM algorithm is developed to adapt the observation noise covariance
on noisy speech cepstra at its input. The estimated parameters are then used in
model-based speech feature enhancement for noise-robust automatic speech recognition.
Experiments on the AURORA4 database lead to improved recognition results with
a linear state model compared to the assumption of stationary noise.
