text: 'In recent years time domain speech separation has excelled over frequency
domain separation in single channel scenarios and noise-free environments. In
this paper we dissect the gains of the time-domain audio separation network (TasNet)
approach by gradually replacing components of an utterance-level permutation invariant
training (u-PIT) based separation system in the frequency domain until the TasNet
system is reached, thus blending components of frequency domain approaches with
those of time domain approaches. Some of the intermediate variants achieve comparable
signal-to-distortion ratio (SDR) gains to TasNet, but retain the advantage of
frequency domain processing: compatibility with classic signal processing tools
such as frequency-domain beamforming and the human interpretability of the masks.
Furthermore, we show that the scale invariant signal-to-distortion ratio (si-SDR)
criterion used as loss function in TasNet is related to a logarithmic mean square
error criterion and that it is this criterion which contributes most reliable
to the performance advantage of TasNet. Finally, we critically assess which gains
in a noise-free single channel environment generalize to more realistic reverberant
conditions.'

text: "Speech activity detection (SAD), which often rests on the fact that the noise
is \"more'' stationary than speech, is particularly challenging in non-stationary
environments, because the time variance of the acoustic scene makes it difficult
to discriminate speech from noise. We propose two approaches to SAD, where one
is based on statistical signal processing, while the other utilizes neural networks.
The former employs sophisticated signal processing to track the noise and speech
energies and is meant to support the case for a resource efficient, unsupervised
signal processing approach.\r\nThe latter introduces a recurrent network layer
that operates on short segments of the input speech to do temporal smoothing in
the presence of non-stationary noise. The systems are tested on the Fearless Steps
challenge database, which consists of the transmission data from the Apollo-11
space mission.\r\nThe statistical SAD achieves comparable detection performance
to earlier proposed neural network based SADs, while the neural network based
approach leads to a decision cost function of 1.07% on the evaluation set of the
2020 Fearless Steps Challenge, which sets a new state of the art."

text: 'Resolving distributed attacks benefits from collaboration between networks.
We present three approaches for the same multi-domain defensive action that can
be applied in such an alliance: 1) Counteract Everywhere, 2) Minimize Countermeasures,
and 3) Minimize Propagation. First, we provide a formula to compute efficiency
of a defense; then we use this formula to compute the efficiency of the approaches
under various circumstances. Finally, we discuss how task execution order and
timing influence defense efficiency. Our results show that the Minimize Propagation
approach is the most efficient method when defending against the chosen attack.'

text: The ability to openly evaluate products, locations and services is an achievement
of the Web 2.0. It has never been easier to inform oneself about the quality of
products or services and possible alternatives. Forming one’s own opinion based
on the impressions of other people can lead to better experiences. However, this
presupposes trust in one’s fellows as well as in the quality of the review platforms.
In previous work on physician reviews and the corresponding websites, it was observed
that there occurs faulty behavior by some reviewers and there were noteworthy
differences in the technical implementation of the portals and in the efforts
of site operators to maintain high quality reviews. These experiences raise new
questions regarding what trust means on review platforms, how trust arises and
how easily it can be destroyed.

text: Remarkable advantages of Containers (CNs) over Virtual Machines (VMs) such
as lower overhead and faster startup has gained the attention of Communication
Service Providers (CSPs) as using CNs for providing Virtual Network Functions
(VNFs) can save costs while increasing the service agility. However, as it is
not feasible to realise all types of VNFs in CNs, the coexistence of VMs and CNs
is proposed. To put VMs and CNs together, an orchestration framework that can
chain services across distributed and heterogeneous domains is required. To this
end, we implemented a framework by extending and consolidating state-of-the-art
tools and technologies originated from Network Function Virtualization (NFV),
Software-defined Networking (SDN) and cloud computing environments. This framework
chains services provisioned across Kubernetes and OpenStack domains. During the
demo, we deploy a service consist of CN- and VM-based VNFs to demonstrate different
features provided by our framework.

text: Service Level Agreements are essential tools enabling clients and telco operators
to specify required quality of service. The 5GTANGO NFV platform enables SLAs
through policies and custom service lifecycle management components. This allows
the operator to trigger certain lifecycle management events for a service, and
the network service developer to define how to execute such events (e.g., how
to scale). In this demo we will demonstrate this unique 5GTANGO concept using
an elastic proxy service supported by a high availability SLA enforced through
a range of traffic regimes.

text: 'Software Defined Networks (SDN) and Network Function Virtualisation (NFV)
provide the basis for autonomous response and mitigation against attacks on networked
computer infrastructures. We propose a new framework that uses SDNs and NFV to
achieve this goal: Secure Autonomous Response Network (SARNET). In a SARNET, an
agent running a control loop constantly assesses the security state of the network
by means of observables. The agent reacts to and resolves security problems, while
learning from its previous decisions. Two main metrics govern the decision process
in a SARNET: impact and efficiency; these metrics can be used to compare and evaluate
countermeasures and are the building blocks for self-learning SARNETs that exhibit
autonomous response. In this paper we present the software implementation of the
SARNET framework, evaluate it in a real-life network and discuss the tradeoffs
between parameters used by the SARNET agent and the efficiency of its actions.'

text: In this paper, we present an IoT architecture which handles stream sensor
data of air pollution. Particle pollution is known as a serious threat to human
health. Along with developments in the use of wireless sensors and the IoT, we
propose an architecture that flexibly measures and processes stream data collected
in real-time by movable and low-cost IoT sensors. Thus, it enables a wide-spread
network of wireless sensors that can follow changes in human behavior. Apart from
stating reasons for the need of such a development and its requirements, we provide
a conceptual design as well as a technological design of such an architecture.
The technological design consists of Kaa and Apache Storm which can collect air
pollution information in real-time and solve various problems to process data
such as missing data and synchronization. This enables us to add a simulation
in which we provide issues that might come up when having our architecture in
use. Together with these issues, we state r easons for choosing specific modules
among candidates. Our architecture combines wireless sensors with the Kaa IoT
framework, an Apache Kafka pipeline and an Apache Storm Data Stream Management
System among others. We even provide open-government data sets that are freely
available.

text: State-of-the-art mechatronic systems offer inherent intelligence that enables
them to autonomously adapt their behavior to current environmental conditions
and to their own system state. This autonomous behavior adaptation is made possible
by software in combination with complex sensor and actuator systems and by sophisticated
information processing, all of which make these systems increasingly complex.
This increasing complexity makes the design process a challenging task and brings
new complex possibilities for operation and maintenance. However, with the risk
of increased system complexity also comes the chance to adapt system behavior
based on current reliability, which in turn increases reliability. The development
of such an adaption strategy requires appropriate methods to evaluate reliability
based on currently selected system behavior. A common approach to implement such
adaptivity is to base system behavior on different working points that are obtained
using multiobjective optimization. During operation, selection among these allows
a changed operating strategy. To allow for multiobjective optimization, an accurate
system model including system reliability is required. This model is repeatedly
evaluated by the optimization algorithm. At present, modeling of system reliability
and synchronization of the models of behavior and reliability is a laborious manual
task and thus very error-prone. Since system behavior is crucial for system reliability,
an integrated model is introduced that integrates system behavior and system reliability.
The proposed approach is used to formulate reliability-related objective functions
for a clutch test rig that are used to compute feasible working points using multiobjective
optimization.

text: Opinion leaders of an investment network can have a significant impact on
capital mar-kets because their investment decisions are adopted by their peers
and trigger large trad-ing cascades, increasing herding behavior and comovement
among stock returns. This paper analyzes the interaction-based relations of traders
from a large social trading plat-form and identifies the driving forces and the
opinion leaders within a large online trading network as the nodes with the highest
centrality and the highest force of infection, respec-tively. Relying on recent
insights from epidemiological research, I maintain that central-ity identifies
the most central traders in the network, while the expected force quantifies the
most influential traders and their spreading power. I study the behavior and charac-teristics
that set central and influential traders apart from other traders. The ability
to identify focal points and their trading behavior within a trading network is
important for investors, investment advisers, and policy makers.

text: Previous research suggests the existence of sentiments in online social networks.
In comparison to real life human interaction, in which sentiments have been shown
to have an influence on human behaviour, it is not yet completely understood which
mechanisms explain how sentiments influence users in online environments. We develop
a theoretical framework that tries to bridge the gap between social influence
theories that focus on offline interactions on one hand and online interaction
in social networks on the other hand. We then test our hypothesis about the influence
and dissemination of sentiments in a quantitative analysis that is based on retrieved
textual messages of communication patterns in over 12000 online social networks.
Our empirical results suggest a general influence of sentiments on node communication
patterns that is evidenced by increased occurrences of subsequent messages that
express the same sentiment polarization. We interpret these findings and suggest
future research to advance our currently limited theories that assume perceived
and generalized social influence to path-dependent social influence models that
consider actual behaviour.

text: In this paper we present a combined hardware/software approach for synchronizing
the sampling clocks of an acoustic sensor network. A first clock frequency offset
estimate is obtained by a time stamp exchange protocol with a low data rate and
computational requirements. The estimate is then postprocessed by a Kalman filter
which exploits the specific properties of the statistics of the frequency offset
estimation error. In long term experiments the deviation between the sampling
oscillators of two sensor nodes never exceeded half a sample with a wired and
with a wireless link between the nodes. The achieved precision enables the estimation
of time difference of arrival values across different hardware devices without
sharing a common sampling hardware.

text: Communication within online social network applications enables users to express
and share sentiments electronically. Existing studies examined the existence or
distribution of sentiments in online communication at a general level or in small-observed
groups. Our paper extends this research by analyzing sentiment exchange within
social networks from an ego-network perspective. We draw from research on social
influence and social attachment to develop theories of node polarization, balance
effects and sentiment mirroring within communication dyads. Our empirical analysis
covers a multitude of social networks in which the sentiment valence of all messages
was determined. Subsequently we studied ego-networks of focal actors (ego) and
their immediate contacts. Results support our theories and indicate that actors
develop polarized sentiments towards individual peers but keep sentiment in balance
on the ego-network level. Further, pairs of nodes tend to establish similar attitudes
towards each other leading to stable and polarized positive or negative relationships

text: Communication in online social networks has been analyzed for some time regarding
the expression of sentiments. So far, very little is known about the relationship
between sentiments and network emergence, dissemination patternsand possible differences
between positive and negative sentiments. The dissemination patterns analyzed
in this study consist of network motifs based on triples of actors and the ties
among them. These motifs are associated with common social network effects to
derive meaningful insights about dissemination activities. The data basis includes
several thousand social networks with textual messages classified according to
embedded positive and negative sentiments. Based on this data, sub-networks are
extracted and analyzed with a dynamic network motif analysis to determine dissemination
patterns and associated network effects. Results indicate that the emergence of
digital social networks exhibits a strong tendency towards reciprocity, followed
by the dominance ofhierarchy as an intermediate step leading to social clustering
with hubs and transitivity effects for both positive and negative sentiments to
the same extend. Sentiments embedded in exchanged textual messages do only play
a secondary role in network emergence and do not express differences regarding
the emergence of network patterns.

text: Microphone arrays represent the basis for many challenging acoustic sensing
tasks. The accuracy of techniques like beamforming directly depends on a precise
knowledge of the relative positions of the sensors used. Unfortunately, for certain
use cases manually measuring the geometry of an array is not feasible due to practical
constraints. In this paper we present an approach to unsupervised shape calibration
of microphone array networks. We developed a hierarchical procedure that first
performs local shape calibration based on coherence analysis and then employs
SRP-PHAT in a network calibration method. Practical experiments demonstrate the
effectiveness of our approach especially for highly reverberant acoustic environments.

text: Safety-critical automotive systems must fulfill hard real-time constraints
to guarantee their reliability and safety requirements. In the context of network-based
electronics systems, high-level timing requirements have to be carefully mastered
and traced throughout the whole development process. In this paper, we outline
the management of scheduling-specific timing information by the application of
a steer-by-wire design example. We apply the principles of the AUTOSAR-compliant
Timing Augmented Description Language (TADL) following the methodology introduced
by the TIMMO project[2]. Focus of the example will be the identification of end-to-end
timing constraints and their refinement by means of stimuli-response event chains.

text: In this paper, we derive an uncertainty decoding rule for automatic speech
recognition (ASR), which accounts for both corrupted observations and inter-frame
correlation. The conditional independence assumption, prevalent in hidden Markov
model-based ASR, is relaxed to obtain a clean speech posterior that is conditioned
on the complete observed feature vector sequence. This is a more informative posterior
than one conditioned only on the current observation. The novel decoding is used
to obtain a transmission-error robust remote ASR system, where the speech capturing
unit is connected to the decoder via an error-prone communication network. We
show how the clean speech posterior can be computed for communication links being
characterized by either bit errors or packet loss. Recognition results are presented
for both distributed and network speech recognition, where in the latter case
common voice-over-IP codecs are employed.

text: 'In order to avoid over-regulation, some countries have experimented with
what might be called threat-based regulation. The idea is - similarly to the contestable
market model - that actual regulation may not be necessary as long as the threat
of regulation is credible. In that case, so the idea, even monopolies will abstain
from setting monopolistic prices in order to avoid being regulated. As experience
from Germany and New Zealand has demonstrated, there are quite a number of problems
associated with threat-based regulatory systems. The most significant problem
has turned out to be the likely under-regulation and according welfare losses
from market power, and in this context, a critical issue that has been identified
is the credibility of the regulatory threat. If the threat of regulation is not
credible, a light-handed regulatory regime (LHRR) amounts to leaving monopolistic
firms unregulated, clearly an undesirable situation from a welfare point of view.
This failure of threat-based regulatory systems results from potential free-rider
problems associated with good corporate behaviour (as in the case of Germany''s
electricity market) as well as the lack of credibility of the threat either because
of the weakness of the enforcement authorities or due to political constraints.
Furthermore, a problem emerges if exercising the threat of regulation implies
an abandonment of the LHRR and a corresponding substitution with heavy-handed
ex ante regulation. An innovative way out of this dilemma has been the quasi-automatic
threshold system originally designed for New Zealand''s electricity distribution
networks, which aims at simulating the pressures that companies would face in
competitive markets. '
