text: 'This paper presents a holistic framework for the transition from diesel to
electric bus networks, crucial for meeting EU regulations targeting 100% zero-emission
urban buses by 2035. We employ a two-phase solution framework: in phase 1, we
solve the Charging Location and Electric Vehicle Scheduling Problem to generate
vehicle schedules that are feasible for electric operation; in phase 2, these
schedules serve as input to a multi-period transition planning model that minimizes
the total cost of ownership while determining fleet replacement and charging infrastructure
deployment. Our experiments show that schedules obtained from solving the integrated
charging location and vehicle scheduling problem significantly outperform traditional
methods, resulting in lower total cost of ownership. Additionally, transition
plans reduce local emissions by up to 85% compared to a diesel-only scenario.
We find that vehicle rotations with long distances and sufficient idle time are
prioritized for electrification, enabling earlier emission reductions and cost
savings. This highlights the importance of adopting vehicle scheduling tailored
for electric buses, rather than relying on legacy diesel schedules.'

text: "Mathematical problem solving is a highly complex competence that needs\r\nto
be supported throughout the learning process. This study examines the role of\r\nproblem-solving
heuristics among 73 sixth-grade students in a German secondary\r\nschool (Gesamtschule).
Specifically, we focus on the empirical relationship between\r\nthe occurrence
of heuristics, their suitability, and application, as well as their contribution\r\nto
problem-solving success. To this end, we developed a heuristic training that\r\nintroduced
strategy keys (heuristic aid cards) accompanied by explanatory videos. By\r\nleveraging
variations in the successful application of the heuristics between students\r\nand
across multiple sessions (73 students in 4 training situations and 3 problems\r\nin
a final test), we discover from regression models with student and task-fixed
effects\r\nthat a successful use of heuristics (i.e., an heuristic occurred, that
heuristic had\r\na high suitability regarding the problem, and it was applied
correctly) leads to more\r\nsuccessful mathematical problem solving. Regarding
the underlying mechanism, we\r\nfind that all dimensions of heuristic use (occurrence,
suitability, and application\r\nof heuristics) are positively related to problem-solving
success. When comparing\r\nthe predictive capacity of all three aspects, we identified
the correct application of\r\nheuristics as particularly conducive for better
problem-solving success. In comparing\r\nthe group of students with high to those
with low initial math competence, we find no significant differences in the relationship
between heuristic use and problemsolving\r\nsuccess across achievement groups.
Our results emphasize the crucial role\r\nof heuristic application in mathematical
problem solving, which generally benefits\r\nstudents regardless of their overall
math competence."

text: Self-piercing riveting (SPR) is a well-established joining technique in lightweight
construction, as it enables the joining of different materials without requiring
pre-drilling. However, the necessary adaptation of the rivet-die combination to
the respective material and thickness combinations requires a large number of
specific tool sets, which significantly limits the process's flexibility. To overcome
these limitations, the versatile self-piercing riveting (V-SPR) was developed,
which features enhanced punch actuation in combination with a multi-range-capable
rivet . In this context, the concept of a movable die was introduced, which enables
an extended process window and adaptable joint formation. Kappe et al. presented
initial studies demonstrating the potential of this approach . However, a detailed
numerical understanding of the underlying mechanisms remains lacking. This paper
presents a numerical analysis of V-SPR with a movable die using a finite element
(FE) model. The model includes deformable rivets, sheet metal materials and a
kinematically controlled die with adjustable movement. A parameter study was conducted
to analyse the influence of die movement on the material flow of the rivet and
sheets, as well as joint formation. The simulations were validated using selected
experimental data. The goal is to compare the joint geometries achieved with fixed
and moving dies and expand the process windows of VSPR. The results demonstrate
that the movable-die concept significantly enhances the material flow of both
the sheets and the rivet, resulting in a noticeably larger and more reliable interlock
than what is achievable with V-SPR using a fixed die. The numerical analyses support
the observations reported by Kappe et al. and extend them by providing a quantitative
description of how die displacement influences the resulting interlock size. Moreover,
the ability to precisely control the die movement makes it possible to join challenging
sheet-metal combinations that are difficult to process with conventional setups,
particularly in cases involving thicker sheet materials.

text: "ABSTRACT\r\n Creativity
and innovation are often understood as the result of a complex interplay of hierarchical
factors, such as national, regional and firm characteristics, or between organisational
and individual factors. While recent applications of qualitative comparative analysis
(QCA) have begun to model such configurational links, their hierarchical nature
has received little empirical attention. As this paper demonstrates, theories
that posit hierarchical configurations can and should be explored using the two‐step
variant of QCA. The paper outlines the potential of the method for the field of
creativity and innovation and helps to navigate key modelling decisions. An illustrative
study explores the occurrence of informal employee innovation behaviour—workarounds—based
on the Ability‐Motivation‐Opportunity (AMO) framework. The results of the two‐step
QCA are superior in terms of reduced limited diversity and complexity to those
of the conventional one‐step QCA. Overall, the method has considerable potential
for empirically capturing the complex, hierarchical interactions inherent in many
innovation processes."

text: "The use of aluminium materials in the structural and bodywork areas of assemblies
has proven to be a targeted option for lightweight design. How-ever, the reliable
and cost-efficient joining of aluminium components remains a challenge. Mechanical
joining methods, such as riveting, are frequently used in the automotive and aerospace
construction industries. Rivets are made from heat-treated steels. Compared to
steel, the use of aluminium materials for fasten-ers offers several advantages
in terms of joining properties, particularly in terms of recyclability, corrosion
resistance and reduced weight of the joined structure. Additionally, the manufacturing
process is shorter since aluminium fasteners do not require coating. However,
aluminium rivets can often not be used due to the insufficient mechanical strength
of the fastener material in relation to the joining component materials.\r\nThis
study systematically investigates the requirements for using solid alu-minium
self-piercing rivets. The influence of rivet geometry adjustments on the joint
quality is analysed using numerical simulation. The results are used to derive
and evaluate an optimised rivet geometry for joining pure aluminium sheets. On
this basis, solid self-drilling rivets with optimised geometry are manufactured
from particle-reinforced aluminium produced in a continuous extrusion process
by machining. The integration of particles increases the material’s strength.
Exper-imental tests are conducted to evaluate the use of optimised solid self-piercing
rivets. The quality-relevant parameters are determined and evaluated based on
macrographs of the joints."
