text: State estimation when only a partial model of a considered system is available
remains a major challenge in many engineering fields. This work proposes a joint,
square-root unscented Kalman filter to estimate states and model uncertainties
simultaneously by linear combinations of physics-motivated library functions.
Using a sparsity promoting approach, a selection of those linear combinations
is chosen and thus an interpretable model can be extracted. Results indicate a
small estimation error compared to a traditional square-root unscented Kalman
filter and exhibit the enhancement of physically meaningful models.

text: 'The development of business models is a challenging task that can be supported
with software tools. Here, existing approaches and tools do not focus on the company’s
situation in which the development takes place (e.g., financial resources, product
type). To tackle this challenge, we used design science research to develop a
situation-specific business model development approach that contains three stages:
First, existing knowledge in terms of tasks to do (e.g., analyze competitive advantage),
and decisions to be made (e.g., social media marketing) are stored in repositories.
Second, the knowledge is used to compose a development method based on the company’s
situation. Third, the development method is enacted to develop a business model.
This demonstration paper presents a tool-support called Situational Business Model
Developer that supports all stages of our approach. We release the tool under
open-source and evaluate it with a case study on developing business models for
mobile apps.'

text: To build successful software products, developers continuously have to discover
what features the users really need. This discovery can be achieved with continuous
experimentation, testing different software variants with distinct user groups,
and deploying the superior variant for all users. However, existing approaches
do not focus on explicit modeling of variants and experiments, which offers advantages
such as traceability of decisions and combinability of experiments. Therefore,
our vision is the provision of model-driven continuous experimentation, which
provides the developer with a framework for structuring the experimentation process.
For that, we introduce the overall concept, apply it to the experimentation on
component-based software architectures and point out future research questions.
In particular, we show the applicability by combining feature models for modeling
the software variants, users, and experiments (i.e., model-driven) with MAPE-K
for the adaptation (i.e., continuous experimentation) and implementing the concept
based on the component-based Angular framework.

text: "Modern services often comprise several components, such as chained virtual
network functions, microservices, or\r\nmachine learning functions. Providing
such services requires to decide how often to instantiate each component, where
to place these instances in the network, how to chain them and route traffic through
them. \r\nTo overcome limitations of conventional, hardwired heuristics, deep
reinforcement learning (DRL) approaches for self-learning network and service
management have emerged recently. These model-free DRL approaches are more flexible
but typically learn tabula rasa, i.e., disregard existing understanding of networks,
services, and their coordination. \r\n\r\nInstead, we propose FutureCoord, a novel
model-based AI approach that leverages existing understanding of networks and
services for more efficient and effective coordination without time-intensive
training. FutureCoord combines Monte Carlo Tree Search with a stochastic traffic
model. This allows FutureCoord to estimate the impact of future incoming traffic
and effectively optimize long-term effects, taking fluctuating demand and Quality
of Service (QoS) requirements into account. Our extensive evaluation based on
real-world network topologies, services, and traffic traces indicates that FutureCoord
clearly outperforms state-of-the-art model-free and model-based approaches with
up to 51% higher flow success ratios."

text: 'This article is dedicated to piezoelectric ultrasonic power transducers that
differ to well known medical ultrasonic diagnostic apparatus or non destructive
testing devices by the level of power in use; typically several tens of up to
more than thousand watts are used in a multitude of different applications. After
a short introduction including historical development, the first focus is on theoretical
background of the operating principle, design and mechanical modeling. As piezoelectric
elements transform electrical to mechanical energy and vice versa, equivalent
circuit modeling is also described. After that, sample applications are delineated
by the matter wherein ultrasound generates unique effects: incredible high pressure
level as well in air as in water, micro-bubbles generating temperature peaks for
very short time instances in fluids, acoustoplastic effect, enhancement of diffusion
and recrystallization in solids, friction manipulation, incremental deformation
and micro-cracking of surfaces, or even generation of macroscopic movements in
motors. At the end, some future directions ranging from novel modeling approaches
to advanced control and new materials are addressed.'

text: The conduction of structure-borne sound through joints causes energy dissipation.
The sound reduction index describes this energy loss as a level decrease in the
particle velocity across series-connected damping elements for which the superposition
principle applies. This simple model can help to develop a testing method for
joints based on this characteristic energy loss. In this paper, this model is
experimentally evaluated for multiple in-series clinched aluminium sheets. Samples
connected by several clinch points arranged in parallel are investigated experimentally,
and the results are discussed.

text: Modeling is an integral part of many computing-related disciplines and thus
also represents a curricular core component in computing education in tertiary
education. Competence models in which modeling is integrated at least to some
extent already exist in some of these disciplines. However, for the core component
of graphical modeling, a competence model that illuminates the relevant competences
in detail is still lacking. Therefore, we develop a competence model for graphical
modeling with the aim to make teaching and especially assessments in the field
more competence-oriented. This paper reports on the first two studies conducted
to develop and validate the competence model for graphical modeling. In the first
study, the structure of the competence model was developed based on theories and
approaches of educational science. Competences relevant for graphical modeling
were deductively derived from literature and existing university course descriptions
using techniques of qualitative content analysis. The result of the first study
is a preliminary competence model. In the second study, the preliminary competence
model was reviewed by means of an expert rating in the modeling community. The
competence model was revised and refined based on these findings and subsequent
expert discussions. The main result of the investigation represents the competence
model for graphical modeling (CMGM), which includes a total of 74 competence facets
at different cognitive process levels in the five content areas of ”model understanding
and interpreting”, ”model building and modifying”, ”values, attitudes, and beliefs”,
”metacognitive knowledge and skills”, and ”social-communicative skills”.

text: AbstractIncreasing system complexity can
be controlled by using systems engineering processes. INCOSE defines processes
with inputs and outputs (artifacts) for this purpose. Specific SE roles are used
to organize the tasks of the processes within the company. In this work, the responsibilities
for artifacts are evaluated by means of the RACI scheme and examined by a cluster
analysis and discussed for a SE transformation project with a German automotive
OEM. As a result of the study, the optimal composition for systems engineering
teams is identified and the systems engineering roles are prioritized.

text: "The development of new business models is essential for startups to become
successful, as well as for established companies to explore new business opportunities.
However, developing such business models is a continuous challenging activity
where different tasks need to be performed, and business decisions need to be
made. Both have to fit the constantly changeable situation in which the business
model is developed to reduce the risk of developing ineffective business models
with low market penetration. Therefore, a method for developing situation-specific
business models is needed. As a solution, we refine the concept of situational
method engineering (SME) to business model development. SME, in turn, provides
means to construct situation-specific development methods out of fragments from
a method repository.\r\n\r\nWe develop a concept for the continuous situation-specific
development of business models based on design science. The approach uses the
roles of a domain expert, a method engineer, and a business developer together
with a repository with method fragments for developing business models and a repository
with modeling artifacts for supporting the development. Both repositories are
filled by utilizing the experience of domain experts. Out of these repositories,
situation-specific development methods for developing business models can be continuously
composed based on the changeable situation by the method engineer and enacted
by the business developer. We implement it as an open-source tool and evaluate
its applicability in an industrial case study of developing a business model for
a local event platform. Our results show that situation awareness supports the
continuous development of business models."

text: This paper presents preliminary work on the formalization of three prominent
cognitive biases in the diagnostic reasoning process over epileptic seizures,
psychogenic seizures and syncopes. Diagnostic reasoning is understood as iterative
exploration of medical evidence. This exploration is represented as a partially
observable Markov decision process where the state (i.e., the correct diagnosis)
is uncertain. Observation likelihoods and belief updates are computed using a
Bayesian network which defines the interrelation between medical risk factors,
diagnoses and potential findings. The decision problem is solved via partially
observable upper confidence bounds for trees in Monte-Carlo planning. We compute
a biased diagnostic exploration policy by altering the generated state transition,
observation and reward during look ahead simulations. The resulting diagnostic
policies reproduce reasoning errors which have only been described informally
in the medical literature. We plan to use this formal representation in the future
to inversely detect and classify biased reasoning in actual diagnostic trajectories
obtained from physicians.

text: In control design most control strategies are model-based and require accurate
models to be applied successfully. Due to simplifications and the model-reality-gap
physics-derived models frequently exhibit deviations from real-world-systems.
Likewise, purely data-driven methods often do not generalise well enough and may
violate physical laws. Recently Physics-Guided Neural Networks (PGNN) and physics-inspired
loss functions separately have shown promising results to conquer these drawbacks.
In this contribution we extend existing methods towards the identification of
non-autonomous systems and propose a combined approach PGNN-L, which uses a PGNN
and a physics-inspired loss term (-L) to successfully identify the system's dynamics,
while maintaining the consistency with physical laws. The proposed method is demonstrated
on two real-world nonlinear systems and outperforms existing techniques regarding
complexity and reliability.

text: 'While trade-offs between modeling effort and model accuracy remain a major
concern with system identification, resorting to data-driven methods often leads
to a complete disregard for physical plausibility. To address this issue, we propose
a physics-guided hybrid approach for modeling non-autonomous systems under control.
Starting from a traditional physics-based model, this is extended by a recurrent
neural network and trained using a sophisticated multi-objective strategy yielding
physically plausible models. While purely data-driven methods fail to produce
satisfying results, experiments conducted on real data reveal substantial accuracy
improvements by our approach compared to a physics-based model. '

text: "Ultrasonic wire bonding is a solid-state joining process used to form electrical
interconnections in micro and\r\npower electronics and batteries. A high frequency
oscillation causes a metallurgical bond deformation in\r\nthe contact area. Due
to the numerous physical influencing factors, it is very difficult to accurately
capture\r\nthis process in a model. Therefore, our goal is to determine a suitable
feed-forward control strategy for the\r\nbonding process even without detailed
model knowledge. We propose the use of batch constrained Bayesian\r\noptimization
for the control design. Hence, Bayesian optimization is precisely adapted to the
application of\r\nbonding: the constraint is used to check one quality feature
of the process and the use of batches leads to\r\nmore efficient experiments.
Our approach is suitable to determine a feed-forward control for the bonding\r\nprocess
that provides very high quality bonds without using a physical model. We also
show that the quality\r\nof the Bayesian optimization based control outperforms
random search as well as manual search by a user.\r\nUsing a simple prior knowledge
model derived from data further improves the quality of the connection.\r\nThe
Bayesian optimization approach offers the possibility to perform a sensitivity
analysis of the control\r\nparameters, which allows to evaluate the influence
of each control parameter on the bond quality. In summary,\r\nBayesian optimization
applied to the bonding process provides an excellent opportunity to develop a
feedforward\r\ncontrol without full modeling of the underlying physical processes."

text: Workshops on business model generation lead to collaborative work phases and
discussions on business models. Therefore, tools such as the Business Model Canvas
are used, typically filled with sticky notes. Generated content needs to be digitized
in a time-consuming manual follow-up as part of the documentation and basis for
a further use of the results in the company. In addition, there are challenges,
such as decentralized work and digital workshop formats. Augmented Reality offers
a way to reduce the digitization effort and enables decentralized work. In this
research, the potentials of the use of AR technology in workshops on business
model generation is investigated. Therefore, functions are implemented and evaluated
in a demonstrator that reduces digitization effort and enable distributed work.

text: Motivated by the prospect of computing agents that explore unknown environments
and construct convex hulls on the nanoscale, we investigate the capabilities and
limitations of a single deterministic finite automaton robot in the three-dimensional
hybrid model for programmable matter. In this model, active robots move on a set
of passive tiles, called configuration, with the geometric shape of rhombic dodecahedra
on the adjacency graph of the face-centered cubic sphere-packing. We show that
the exploration problem is equally hard in the hybrid model and in three-dimensional
mazes, in which tiles have the shape of cubes and are positioned at the vertices
of $\mathbb{Z}^3$. Thereby, a single robot with a constant number of pebbles cannot
solve this problem in the hybrid model on arbitrary configurations. We provide
algorithms for a robot with two pebbles that solve the exploration problem in
the subclass of compact configurations of size $n$ in $\O(n^3)$ rounds. Further,
we investigate the robot's capabilities of detection and hull construction in
terms of restricted orientation convexity. We show that a robot without any pebble
can detect strong $\O$-convexity in $\O(n)$ rounds, but cannot detect weak $\O$-convexity,
not even if provided with a single pebble. Assuming that a robot can construct
tiles from scratch and deconstruct previously constructed tiles, we show that
the strong $\O$-hull of any given configuration of size $n$ can be constructed
in $\O(n^4)$ rounds, even if the robot cannot distinguish constructed from native
tiles.

text: 'The development of effective business models is an essential task in highly
competitive markets like mobile ecosystems. Existing development methods for these
business models do not specifically focus that the development process profoundly
depends on the situation (e.g., market size, regulations) of the mobile app developer.
Here, a mismatch between method and situation can lead to poor resource management
and longer development cycles. In software engineering, situational method engineering
is used for software projects to configure a development method out of a method
repository based on the project situation. Analogously, we support creating situation-specific
business model development methods with a method base and new user roles. Here,
the method engineer obtains the knowledge of the domain expert and stores it in
the method base as elements, building blocks, and patterns. The expert knowledge
is derived from a grey literature review on mobile development processes. After
this, the method engineer constructs the development method based on the described
situation of the business developer. We provide an open-source tool and evaluate
it by constructing a local event platform''s business model development method. '

text: "Developing effective business models is a complex process for a company where
several tasks (e.g., conduct customer interviews) need to be accomplished, and
decisions (e.g., advertisement as a revenue stream) must be made. Here, domain
experts can guide the choices of tasks and decisions with their knowledge. Nevertheless,
this knowledge needs to match the situation of the company (e.g., financial resources)
and the application domain of the product/service (e.g., mobile app) to reduce
the risk of developing ineffective business models with low market penetration.
This is not covered by one-size-fits-all development methods without tailoring
before the enaction.\r\nTherefore, we conduct a design science study to create
a situation-specific development approach for business models. Based on situational
method engineering and our previous work in storing knowledge of methods and models
in distinct repositories, this paper shows the situation-specific composition
and enaction of business model development methods. First, the method engineer
composes the development method out of both repositories based on the situational
context. Second, the business developer enacts the method and develops the business
model. We implement the approach in a tool and evaluate it with a industrial
case study on mobile apps."
