text: "ABSTRACT\r\n \r\n The
integration of heat pumps offers a promising route for electrifying chemical processes
and reducing CO\r\n 2\r\n emissions.
Their feasibility strongly depends on the temperature levels and the quantities
of available heat sources and sinks, which can be influenced by adjusting process
operating parameters to enhance integration potential. The number and quality
of these sources and sinks also determine suitable heat pump configurations and
therefore the technical and economic viability of implementation. In addition,
refrigerant selection is a critical factor, as it is restricted by regulations
such as the F‐Gas Regulation. This study investigates how different operating
parameters affect the integration potential of various heat pump configurations
in a CO\r\n 2\r\n absorption
process using MEA as solvent. Furthermore, economic evaluations are carried out
considering different electricity price scenarios and allowable refrigerants.\r\n

text: "Abstract\r\n In this chapter,
the precision of optical clocks based on mode-locked laser (MLL) is compared with
more conventional types of clock sources. It is shown that the phase noise of
the optical pulse train from the MLL can be better than other types of clock sources
by orders of magnitude. Then, an abstract representation of frequency synthesizer
is demonstrated. Different techniques for RF generation using MLL are shown, and
their pros and cons are discussed. Finally, a comparison of all these techniques
is made with respect to their phase noise and capability to generate RF signal
with different frequencies for different applications."

text: Electrifying the heating sector is essential for achieving global climate
targets like the Paris Agreement’s 1.5 °C goal. In Germany, where 80 % of household
energy goes to space heating and hot water, shifting to low-carbon solutions is
crucial. Fossil-fuelled district heating networks can incorporate renewable energy
via heat pumps, improving efficiency. Although heat pump design typically favours
minimal temperature lifts, higher lifts can be economically viable with low electricity
prices and abundant renewables. Adding thermal energy storage boosts operational
flexibility. This study explores a flexible heat pump operation incorporating
part load behaviour with a thermal energy storage in a German city’s district
heating system to minimise costs and carbon dioxide emissions. Using a mixed-integer
linear programming model, it examines the impact of temperature adjustments and
storage on system efficiency. The results show that the integration of a heat
pump in a district heating system reduces operating costs. Compared to a supply
without a heat pump, with levelised cost of heating of 9.98 cent/kWhth and a fixed
operating mode with costs between 9.96 cent/kWhth and 11.49 cent/kWhth, the flexible
use results in lowest costs of 9.85 cent/kWhth, while also reducing overall CO2
emissions. Using a full factorial sensitivity analysis, the levelised cost of
heating ranged between 9.15 cent/kWhth in the best case and 10.37 cent/kWhth in
the worst case for the selected configuration.

text: "Industrial electrification is increasing to reduce fossil fuel dependence,
alongside a growing share of volatile renewables.\r\nA secure and reliable energy
supply is crucial for industry, leading to a shift from centralised to decentralised
grid structures.\r\nDC microgrids becoming increasingly popular in industry, since
they enable energy recuperation from braking, reduce components and cables, and
integrate storage and local generation to manage supply interruptions or peak
loads.\r\nEVs add further synergies by serving as mobile storage units, helping
to store and redistribute locally generated renewable energy.\r\nThis paper analyses
how EV integration in droop-controlled DC grids can contribute to a more stable,
low-emission and peak-reduced load profile to the supply grid through load shifting
and bridge interruptions.\r\nA droop-controlled DC grid model has been developed,
incorporating an EV charging park based on probability functions.\r\nScalable
scenarios allow for diverse condition analysis using an energy management system
that utilises fuzzy logic and sequential MILP optimisation.\r\nIt has been shown
that a 7% improvement of coefficient represented grid-serving behaviour is possible
by load shifting.\r\nIt has also been demonstrated that an optimised EMS can reduce
the demand-based CO2 emissions by 41kg for a representative day compared to a
fuzzy logic EMS.\r\nAt the same time peak load is decreased yielding a more constant
residual load.\r\nThese results highlight the potential of a controlled bidirectional
charging infrastructure in DC grids and underscore the need to explicitly consider
charging processes to ensure a residual load as constant as possible."

text: 'Information systems (IS) research is increasingly exploring the potential
of generative artificial intelligence (GenAI), such as large language models (LLMs).
For design science research (DSR), such technologies foster entirely new vistas
for the design of IT artifacts that make use of their generative capabilities,
but also influence DSR methodology. This shift is much more profound than it has
been discussed so far. To identify existing implications of GenAI for design-oriented
research in IS, we report results from an integrative literature review of recent
DSR publications in leading IS outlets. Thereby, we synthesize five major theoretical
challenges that arise when using GenAI in DSR projects: (1) an obscure composition
of the artifact, (2) an opaque contextualization of the LLM, (3) a fragile internal
consistency of the artifact, (4) a rapid erosion of prescriptive knowledge, and
(5) missing methodological guidance. We investigate these challenges and conceptualize
a set of three guidelines that inform DSR in the rising era of GenAI. These guidelines
support researchers in designing and justifying GenAI-related DSR processes and
in precisely articulating the theoretical grounding of their design decisions
and evaluation strategies.'

text: "Abstract\r\n In this work,
we address the numerical identification of entanglement in dynamical scenarios.
To this end, we consider different programs based on the restriction of the evolution
to the set of separable (i.e., non-entangled) states, together with the discretization
of the space of variables for numerical computations. As a first approach, we
apply linear splitting methods to the restricted, continuous equations of motion
derived from variational principles. We utilize an exchange interaction Hamiltonian
to confirm that the numerical and analytical solutions coincide in the limit of
small time steps. The application to different Hamiltonians shows the wide applicability
of the method to detect dynamical entanglement. To avoid the derivation of analytical
solutions for complex dynamics, we consider variational, numerical integration
schemes, introducing a variational discretization for Lagrangians linear in velocities.
Here, we examine and compare two approaches: one in which the system is discretized
before the restriction is applied, and another in which the restriction precedes
the discretization. We find that the ‘first-discretize-then-restrict’ method becomes
numerically unstable, already for the example of an exchange-interaction Hamiltonian,
which can be an important consideration for the numerical analysis of constrained
quantum dynamics. Thereby, broadly applicable numerical tools, including their
limitations, for studying entanglement over time are established for assessing
the entangling power of processes that are used in quantum information theory."

text: This paper investigates the potential impacts of digitalisation on society
and democratic governance through the construction of four realist science fiction
scenarios. The study aims to delineate desirable and undesirable digital futures
to inform policy discourse and strategic planning. It begins with the outlining
of the research basis and methodology, where it employs a methodological synthesis
of the Scenario Development Technique from the UN Strategic Foresight Guide and
STEEP Analysis. This approach integrates a macro environmental assessment of socio-cultural,
technological, economic, environmental, and political dimensions to identify key
drivers of change and differences. These are then mapped onto a two-by-two matrix
defined by two primary axes. This combination enabled the development of four
scenarios examining the impact of digital technologies across these dimensions.
The scenarios diverge along two axes. The vertical axis represents the mode of
societal organisation and political power (authoritarianism versus democracy).
The horizontal axis represents the mode of governance and citizen engagement (representation
versus participation). By contrasting these divergent paths, this paper provides
a critical framework for analysing how digital technologies intersect with political
will and socioeconomic structures.

text: This article explores the relativity of Islamic normativity through the taṣwīb
doctrine (kullu mujtahid muṣīb) as formulated by al-ʿAnbarī and received by al-Jāḥiẓ
(d. 255/869), al-Jaṣṣāṣ (d. 370/981), and al-Baṣrī (d. 436/1044). Al-Jaṣṣāṣ reinterprets
the thesis through the ḥanafī principle of ashbah bi-l-aṣl as a hermeneutical-methodological
approach; al-Baṣrī elaborates it into an epistemo-logical model of normative plurality,
while al-Jāḥiẓ articulates a soteriological theory of moral responsibility in
the context of kalām. The analysis shows that classical Islamic legal theory developed
a distinct modelof normativity that maintains binding force under conditions of
pluralism and uncertainty. The article calls for renewed engagement with this
tradition in contemporary debates on religious normativity and legal pluralism.

text: Simulation-based design of high-power ultrasonic systems depends on the accurate
modelling of the electromechanical behaviour of piezoceramic materials. In practical
transducer applications, the relevant operating points are influenced by mechanical
preload and heating, both of which give rise to changes in the elastic, dielectric,
and piezoelectric material properties. Material parameters identified under idealised,
unloaded conditions are therefore insufficient to represent piezoceramic material
behaviour under realistic operating conditions. To overcome this limitation, experimental
setups are developed that enable the measurement of electrical impedance spectra
under controlled thermal and mechanical conditions. The acquired impedance data
are used in an inverse identification procedure, in which the behaviour of a finite
element forward model is iteratively fitted to the measurements using a block
coordinate descent optimisation strategy guided by a sensitivity analysis. This
yields effective linear material parameters as a function of temperature and mechanical
stress at varying operating points. The identified temperature-dependent parameters,
for instance, can be employed in a coupled thermo-electromechanical simulation
framework to predict the temperature-dependent material behaviour during operation.
The linear identification based on varying operation points provides an initial
approximation of the nonlinear material response, establishing a basis for the
development of corresponding nonlinear material models.
