text: We contribute to the theoretical understanding of randomized search heuristics
for dynamic problems. We consider the classical graph coloring problem and investigate
the dynamic setting where edges are added to the current graph. We then analyze
the expected time for randomized search heuristics to recompute high quality solutions.
This includes the (1+1) EA and RLS in a setting where the number of colors is
bounded and we are minimizing the number of conflicts as well as iterated local
search algorithms that use an unbounded color palette and aim to use the smallest
colors and - as a consequence - the smallest number of colors. We identify classes
of bipartite graphs where reoptimization is as hard as or even harder than optimization
from scratch, i. e. starting with a random initialization. Even adding a single
edge can lead to hard symmetry problems. However, graph classes that are hard
for one algorithm turn out to be easy for others. In most cases our bounds show
that reoptimization is faster than optimizing from scratch. Furthermore, we show
how to speed up computations by using problem specific operators concentrating
on parts of the graph where changes have occurred.

text: Research has shown that for many single-objective graph problems where optimum
solutions are composed of low weight sub-graphs, such as the minimum spanning
tree problem (MST), mutation operators favoring low weight edges show superior
performance. Intuitively, similar observations should hold for multi-criteria
variants of such problems. In this work, we focus on the multi-criteria MST problem.
A thorough experimental study is conducted where we estimate the probability of
edges being part of non-dominated spanning trees as a function of the edges’ non-domination
level or domination count, respectively. Building on gained insights, we propose
several biased one-edge-exchange mutation operators that differ in the used edge-selection
probability distribution (biased towards edges of low rank). Our empirical analysis
shows that among different graph types (dense and sparse) and edge weight types
(both uniformly random and combinations of Euclidean and uniformly random) biased
edge-selection strategies perform superior in contrast to the baseline uniform
edge-selection. Our findings are in particular strong for dense graphs.

text: The $$\textbackslash mathcal NP$$-hard multi-criteria shortest path problem
(mcSPP) is of utmost practical relevance, e.~g., in navigation system design and
logistics. We address the problem of approximating the Pareto-front of the mcSPP
with sum objectives. We do so by proposing a new mutation operator for multi-objective
evolutionary algorithms that solves single-objective versions of the shortest
path problem on subgraphs. A rigorous empirical benchmark on a diverse set of
problem instances shows the effectiveness of the approach in comparison to a well-known
mutation operator in terms of convergence speed and approximation quality. In
addition, we glance at the neighbourhood structure and similarity of obtained
Pareto-optimal solutions and derive promising directions for future work.

text: The Arburg Plastic Freeforming (APF) is an additive manufacturing process
that allows three-dimensional, thermoplastic components to be produced in layer
by layer. The components are generated by depositing fine, molten plastic droplets.
One of the main advantages of the APF process is the open machine control. Thus,
the process parameters can be adapted and optimized for the individual applications.
The optimization is carried out on the basis of a variation of the process parameters
using a statistical design of experiments. Relevant process parameters are the
layer thickness, the form factor, the raster and delta angle as well as the overlap
between the contour and the filling of a layer. In addition, the nozzle and build
chamber temperatures are varied. Using this procedure, the effects of the influencing
parameters on the mechanical properties and the interactions between the influencing
parameters are analyzed and converted into mathematical models. On the basis of
the results and the models, guidelines will be developed to assist the user of
APF technology in the systematic process configuration for their own applications.
The material used is ABS, one of the most frequently used amorphous thermoplastics
in additive manufacturing. The mechanical properties are determined on the basis
of tensile tests and the characteristic values tensile strength, elongation at
break and Young's modulus. The results should show the performance of the APF
technology in regard to the mechanical properties.

text: This paper studies the performance of improper Gaussian signaling
(IGS) over a 2-user Rayleigh single-input single-output (SISO) interference channel,
treating interference as noise. We assume that the receivers have perfect channel
state information (CSI), while the transmitters have access to only statistical
CSI. Under these assumptions, we consider a signaling scheme, which we refer to
as proper/improper Gaussian signaling or PGS/IGS, where at most one user may employ
IGS. For the Rayleigh fading channel model, we characterize the statistical distribution
of the signal-to-interference-plus-noise ratio at each receiver and derive closed-form
expressions for the ergodic rates. By adapting the powers, we characterize the
Pareto boundary of the ergodic rate region for the 2-user fading IC. The ergodic
transmission rates can be attained using fixed-rate codebooks and no optimization
is involved. Our results show that, in the moderate and strong interference regimes,
the proposed PGS/IGS scheme improves the performance with respect to the PGS scheme.
Additionally, we numerically compute the ergodic rate region of the full IGS scheme
when both users can employ IGS and their transmission parameters are optimized
by an exhaustive search. Our results suggest that most of the Pareto optimal points
for the 2-user fading IC channel are attained when either both users transmit
PGS or when one transmits PGS and the other transmits maximally improper Gaussian
signals and time sharing is allowed.

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.

text: We tackle a bi-objective dynamic orienteering problem where customer requests
arise as time passes by. The goal is to minimize the tour length traveled by a
single delivery vehicle while simultaneously keeping the number of dismissed dynamic
customers to a minimum. We propose a dynamic Evolutionary Multi-Objective Algorithm
which is grounded on insights gained from a previous series of work on an a-posteriori
version of the problem, where all request times are known in advance. In our experiments,
we simulate different decision maker strategies and evaluate the development of
the Pareto-front approximations on exemplary problem instances. It turns out,
that despite severely reduced computational budget and no oracle-knowledge of
request times the dynamic EMOA is capable of producing approximations which partially
dominate the results of the a-posteriori EMOA and dynamic integer linear programming
strategies.

text: A multiobjective perspective onto common performance measures such as the
PAR10 score or the expected runtime of single-objective stochastic solvers is
presented by directly investigating the tradeoff between the fraction of failed
runs and the average runtime. Multi-objective indicators operating in the bi-objective
space allow for an overall performance comparison on a set of instances paving
the way for instance-based automated algorithm selection techniques.

text: 'Es existieren bisher zahlreiche Studien, die das Potenzial von Augmented
Reality (AR) in verschiedenen Bildungsbereichen und seine Auswirkungen auf die
Lernenden hinsichtlich ihrer erhöhten Motivation, verbesserter Lernfähigkeit,
Konzentration auf das Thema usw. hervorheben. Dabei eignen sich AR-Anwendungen
sowohl für den Einsatz in formellen, als auch informellen Lernumgebungen und Bildungsinstitutionen,
beginnend mit Kunstkursen in Vorschulen über Biologie, Geschichte, Chemie, Physik
etc. in weiterführenden Schulen und Universitäten [1]. Trotz der steigenden Zahl
an Studien liegen nur wenigen AR-Anwendungen ein geeignetes didaktisches Konzept
zu Grunde. Ferner fehlen allgemeine Studien, die die lernfördernden Eigenschaften
von AR im Bereich der Vorbereitung und Begleitung von Laborpraktika untersuchen.
Aktuelle Anwendungen erweitern lediglich gedruckte Lerninhalte mit zusätzlichen
Links, Videos oder statischen 3D-Modellen oder benötigen spezielle Voraussetzung
für die Nutzung der AR-Anwendung [2]. Der vorliegende Beitrag untersucht und konzentriert
sich daher auf ein didaktisches Konzept für eine auf mobilen Geräten basierende
AR-Anwendung (App) zum Erwerb und zur Vertiefung praktischer Fertigkeiten im Umgang
mit elektrotechnischen Laborgeräten und -komponenten. In einer früheren Arbeit
wurden die Möglichkeiten und Grenzen der AR-Technologie in der Ingenieurausbildung
mit besonderem Fokus auf Laborarbeit untersucht, um häufige Fehler im Designkonzept
zu vermeiden. Das didaktische Grundkonzept beruht auf dem „Constructive Alignement“
nach Biggs [3] mit der Definition der drei obligatorischen Schritte: Lernziele,
Lehr- / Lernaktivitäten und Prüfungsmethoden. Die Lernziele werden – angelehnt
an die modifizierte Bloom-Taxonomie nach Anderson und Krathwohl [4] – weiter konkretisiert,
woraus dann im weiteren Schritt mögliche Lehrszenarien in AR gestaltet wurden.'

text: "There have been numerous studies highlighting the potential of Augmented
Reality (AR) in different educational settings and its impacts on learners in
terms of increased motivation, learning, focus, and more. AR applications are
suitable for use in formal as well as informal learning environments and educational
institutions, starting with art courses in pre-schools or biology, history, chemistry,
physics etc. in secondary schools and universities. Despite the increasing number
of studies, only a few AR applications are based on a suitable didactic principle.
In addition, there is a lack of general studies investigating the learning-promoting
characteristics of AR in the field of preparation and conduction of laboratory
trainings. Current studies merely extend printed learning content with additional
links, videos, or static 3D models or require special prerequisites for using
the AR application.\r\nTherefore, this article examines and focuses on a design
concept for a mobile-based AR application (App) for acquiring and deepening practical
skills in handling laboratory equipment and components. In a previous work, the
possibilities and limitations of AR technology in engineering education, with
a particular focus on laboratory work, were investigated in order to avoid frequent
design mistakes. The didactic concept in this project is based on the constructive
alignment according to Biggs with the definition of the three compulsory steps:
learning objectives (or intended learning outcome), teaching / learning activities
and assessments. The learning objectives were further concretized in the next
step, based on the revised Bloom taxonomy according to Anderson and Krathwohl
to derive and design possible teaching scenarios in AR. "

text: Structural parts for aviation have very high demands on the development and
production process. Therefore, the entire process must be considered in order
to produce high-quality AM metal parts. In this case study, a conventional part
was selected to be optimized for AM. The process presented includes component
selection, design improvement with a novel approach for topology optimization
based on the AMendate algorithm as basis of MSC Apex Generative Design,component
production on a SLM 250 HL and post-processing including heat treatment and surface
smoothing. With the topology optimization a weight reduction of ~60 % could be
realized, whereby the stress distribution is more homogeneous. Furthermore, the
challenges of support optimization and post-processing have to be addressed, in
order to produce competitive parts.

text: Herein we present a new proton-conducting iron(II) metal–organic framework
(MOF) of an unusual structure formed by chains of alternating bistriazolate-p-benzoquinone
anions and iron(II) cations with four axially coordinated water molecules. These
chains assemble via π–π stacking between the aromatic units to form a three-dimensional
grid-like network with channel pores filled with water molecules. The material
was structurally characterized by single-crystal XRD analysis, and its water and
thermal stability was investigated. The proton conductivity was studied by impedance
measurements on needle-like single crystals. A simple but efficient measurement
setup consisting of interdigital electrodes was used. The influence of the crystal
orientation, temperature, and humidity was investigated. The iron(II)-MOF showed
the highest proton conductivity of 3.3·10–3 S cm–1 at 22 °C and 94% relative humidity.
Contrary to most known structures, the conductivity in this material is controlled
by chemical properties of the pore system rather than by grain boundaries. The
presented material is the starting point for further tailoring the proton-conducting
properties, independent of morphological features which could find potential applications
as membrane materials in proton-exchange membrane fuel cells.

text: According to ISO / ASTM 52900, additive manufacturing (AM) is defined as "the
process of joining materials to make parts from 3D model data, usually layer upon
layer, as opposed to conventional manufacturing including subtractive manufacturing
technologies and formative manufacturing methodologies” [1]. This results in significant
advantages over conventional manufacturing methodologies, such as the production
of topologically optimized, complex structures, lower material consumption or
shorter product development cycles. In order to be able to use these advantages,
the possibilities and restrictions of the processes must be known. In particular,
selective laser beam melting (SLM), in which a powdery metallic starting material
is melted by means of a laser, requires a sound understanding of the process.
For this purpose, design guidelines have been presented in various scientific
papers. These design guidelines help to design a component in such a way that
it can be manufactured successfully using additive manufacturing. These so-called
“AMsuitable design guidelines” can be found among others at Adam, Kranz and Thomas
[2,3,4,5]. In contrast to established manufacturing processes, the post-processing
of additive components is divided into two steps. First, the AM immanent post
processing, such as the removing of the component from the building platform or
the removing of the remaining powder. These post-processing steps are in the following
referred to “post-processing”. Secondly, the subsequent post-processing steps
to improve the component properties, such as milling and turning or a stress-relief
annealing. These are referred to as “finishing” and form the focus of this paper.
With regard to a successful finishing of additively manufactured components, design
guidelines must be taken into account that consider the finishing inherent restrictions
and possibilities. In the following, these design guidelines are referred to “finishing
suitable”. They can deviate significantly from those of conventionally manufactured
components in the case of additively manufactured components. Although there are
some investigations that deal with the post-processing of additively manufactured
components [6,7], there are hardly any design guidelines that are suitable for
finishing [8]. Therefore, knowledge about the finishing of additively manufactured
components is based on experimental experience rather than on scientific knowledge.
For this reason, design guidelines for a finishing suitable design must be methodically
determined and quantified. These quantified design guidelines can be used for
an automated design check on complex components like topology optimized geometries.
