text: Refill friction stir spot welding (RFSSW) is a highly flexible and promising
solid-state joining method for aluminium alloys. Alternatively, resistance spot
welding (RSW) can be stated as an appropriate joining method which can be automated
and used within a high-volume production due to short process times. Both processes
do not need any additional elements and a flat surface on both sides of the joints
can be realised. In order to meet the modern requirements for crash safety and
structural stiffness, thermal and mechanical joining methods are mainly combined
by using single-component epoxy resin adhesives. Due to an insufficient knowledge
about the application of both thermal joining methods for the abovementioned material
combinations combined with additional adhesives, deeper investigations were done
regarding the interactions of the polymers and the joining processes. Starting
with a brief presentation of the boundary conditions of the investigations and
the refill friction stir spot welding and resistance spot welding of high-strength
aluminium alloys with sheet thicknesses bigger than 5.8 mm, the paper introduces
the process-related joint properties of friction-based and resistance-based welded
joints. Afterwards, the paper discusses the influences of the process parameter
on the metallographic joint formation and load-bearing capacities for a selected
two-sheet and four-sheet material combination. When combining the spot welding
technologies with adhesives, the process parameters of the RFSSW process have
to be adapted for the two-sheet combination by adding a squeeze-out step, while
for RSW, just the preholding time has to be increased. Different challenges for
both joining methods are shown. For RFSSW, the gap formation has to be considered
when welding big total sheet thicknesses, while for RSW, the shape of the weld
nugget is more important for an appropriate joint performance. Additionally, process
optimisations for less adhesive incineration will be discussed for both joining
processes, and the influences of the adhesive on the joint formation will be addressed
with the help of load-bearing capacity evaluations. The paper closes with specific
recommendations for the realisation of refill friction stir and resistance spot-welded
joints with and without adhesive in the field of Al joints with big total sheet
thicknesses which meet the quality demands and an outlook for further research
steps will be given.

text: Monitoring systems for machines, plants, materials and equipment are increasingly
used in production processes. These online condition monitoring systems can detect
damage or excessive loads at an early stage and can drastically reduce or prevent
long downtimes of plants and machines as well as high repair and maintenance costs.
This paper depicts a method for online crack detection with pattern recognition
methods for specimens joined by self-pierce riveting under cyclic load in fatigue
tests (laboratory application). A software specially conceived for this application
was developed. This software, AnrissMF, uses active acoustic testing with a structure-borne
sensor to detect cracks in the joints at a very early stage. It is shown in this
paper that this software can detect cracks much earlier than classical failure
criteria for joints (i. e. before any drop in stiffness or frequency is observed).
Furthermore, the successful application of software AnrissMF for online crack
detection during the fatigue strength test is presented.

text: The purpose of this study is to experimentally test Trockel’s game,
which is a modelling of the classical Chain Store Game (CSG), and determine whether
one of the two theories of Equality and Deterrence may better account for the
observed behavior. The CSG is an example of a simple game in extensive form where
the actual behavior of well-informed players cannot be expected to agree with
the clear results of game theoretical reasoning. To explain the disagreement between
the theory and the expected behavior, Trockel’s game is proposed as an alternative
modelling of the scenario. The existence of more than one equilibrium in Trockel’s
game opens a door for reputation building. This study is the first attempt to
experimentally test this alternative game with the same purpose. According to
my data, there is some evidence in favor of both Equality and Deterrence Hypotheses.
However, since the strategies compatible with the Equality Hypothesis are played
more frequently, I observe some patterns which share the same intuition with the
Deterrence Hypothesis.

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: 'Non-GAAP reporting is under debate as managers may opportunistically inflate
non-GAAP earnings. By separating firms into groups based on exclusions of recurring
expenses before material restatements occur this paper investigates whether market
participants are misled based on ex-ante non-GAAP reporting. The results show
a decline in cumulative abnormal returns (–11.8% aggressive non-GAAP Reporting
vs. –2.7% non-aggressive non-GAAP reporting), reduction in overvaluation (–22.18%
vs. no decline) and losses in the earnings response coefficient (–51.8% vs. no
significant decline) for firms with prior aggressive non-GAAP reporting. Further,
we document that investors are less responsive to aggressively reported non-GAAP
earnings ex-post, indicating that increased attention enhances investor’s ability
to see through the quality of non-GAAP exclusions. '

text: Employing a sample of 492 merger and acquisition (M&A) announcements from
284 acquirers across North America and Europe between 2005 and 2018, this study
analyzes the impact of M&A announcements on an acquirers abnormal CDS spread changes.
We find that spreads from CDS which are written on acquirers increase by 310 bps
during a symmetric five-day event window suggesting that investors expect an increase
in the acquirers credit risk exposure due to M&As. Next to this baseline finding,
we conduct a large variety of sensitivity analyses to gain more insight into the
driving factors of the rising risk perception of CDS investors due to M&A announcements.

text: Employing main and sector-specific investment-grade CDS indices from the North
American and European CDS market and performing mean-variance out-of-sample analyses
for conservative and aggressive investors over the period from 2006 to 2014, this
paper analyzes portfolio benefits of adding corporate CDS indices to a traditional
financial portfolio consisting of stock and sovereign bond indices. As a baseline
result, we initially find an increase in portfolio (downside) risk-diversification
when adding CDS indices, which is observed irrespective of both CDS markets, investor-types
and different sub-periods, including the global financial crisis and European
sovereign debt crisis. In addition, the analysis reveals higher portfolio excess
returns and performance in CDS index portfolios, however, these effects clearly
differ between markets, investor-types and sub-periods. Overall, portfolio benefits
of adding CDS indices mainly result from the fact that institutional investors
replace sovereign bond indices rather than stock indices by CDS indices due to
better risk-return characteristics. Our baseline findings remain robust under
a variety of robustness checks. Results from sensitivity analyses provide further
important implications for institutional investors with a strategic focus on a
long-term conservative portfolio management.

text: Employing credit default swap (CDS) data for a sample of 52 major banks across
18 countries from 2008 to 2016, this paper investigates determinants of the outstanding
net notional amount of CDS which are written on banks. We extend the current literature
dealing with CDS trading by analyzing further CDS trading-specific, fundamental
bank-specific as well as macroeconomic and institutional determinants with a focus
on bank CDS trading. We find that, next to well-discussed determinants for corporate
firms in the literature, especially a bank's tail risk, capital adequacy, loan
portfolio and business model affect a bank's outstanding CDS net notional. This
finding indicates that investors in the bank CDS market partly have a recourse
to a fundamental analysis for their investment decision. Our study fills an important
gap since empirical studies have solely focused on sovereign and corporate CDS
yet. In addition, the analysis at hand provides important implications for both
academics and practitioners since understanding the trading motives of bank CDS
investors gives deeper insights into the still opaque CDS market.

text: Recent years have seen the emergence of physical products that are digitally
networked with other products and with information systems to enable complex business
scenarios in manufacturing, mobility, or healthcare. These “smart products”, which
enable the co-creation of “smart service” that is based on monitoring, optimization,
remote control, and autonomous adaptation of products, profoundly transform service
systems into what we call “smart service systems”. In a multi-method study that
includes conceptual research and qualitative data from in-depth interviews, we
conceptualize “smart service” and “smart service systems” based on using smart
products as boundary objects that integrate service consumers’ and service providers’
resources and activities. Smart products allow both actors to retrieve and to
analyze aggregated field evidence and to adapt service systems based on contextual
data. We discuss the implications that the introduction of smart service systems
have for foundational concepts of service science and conclude that smart service
systems are characterized by technology-mediated, continuous, and routinized interactions.
