Student Evaluation

description: While the guide “How to use the evaluation tool” explains how HEI staff members can use the AsCOLA evaluation tool, this guide focuses on interpreting the outcomes for each evaluation topic and understanding their implications for the (re)development of your course.

AsCOLA is an acronym which stands for “Assessing Courses of the Online Learning Agreement”. An Erasmus+ Key Action 2 project, AsCOLA aims to enhance and digitalise the quality framework of Erasmus+ student mobility and contribute to closing the data gap in the quality aspect of higher education transformation. The project will help higher education institutions (HEIs) better monitor and assess their institutional performance in education activities related to their internationalisation strategy and policy.

description: We have developed a simulation model to describe particle adsorption to and desorption from liquid interfaces. Using this model we formulate a closed interfacial equation of state for repulsive elastic spheres. The effect of a long-range attractive interaction is introduced by perturbation theory, and the effect a short-range attraction is studied using direct simulation. Based on our model predictions we conclude that for polymeric particles the surface pressure cannot be modelled directly by inert particles that interact via some effective potential. Internal degrees of freedom within gel particles are all-important. Consequently, the surface pressure of a fully packed layer is not proportional to kT/d^2, where d is the particle diameter; but proportional to kT/dm^2, where dm is the size of the molecular units that make up the particle. This increases the surface pressure and modulus by some four orders of magnitude. For short range interaction we study the dynamic behaviour, and find fractal-like structures at low concentrations. At intermediate coverage an irregular structure is formed that resembles a spinodal system. This system freezes, which arrests the spinodal structure. At high surface coverage the simulations show poly-crystalline domains. For dilute systems, the strength of the surface layers is determined by simulated compression and expansion. We find a power law for the surface pressure (Pi ~ Gamma^10+/-0.5), which is related to the (fractal) structure of the adsorbed network. The power law is consistent with surface percolation.

description: We reconsider non-minimal λϕ^4 chaotic inflation which includes the gravitational coupling term ξ\mathcal{R} ϕ^2, where ϕdenotes a gauge singlet inflaton field and \mathcal{R} is the Ricci scalar. For ξ>> 1 we require, following recent discussions, that the energy scale λ^{1/4} m_P / \sqrtξ for inflation should not exceed the effective UV cut-off scale m_P / ξ, where m_P denotes the reduced Planck scale. The predictions for the tensor to scalar ratio r and the scalar spectral index n_s are found to lie within the WMAP 1-σbounds for 10^{-12} < λ< 10^{-4} and 10^{-3} < ξ< 10^2. In contrast, the corresponding predictions of minimal λϕ^4 chaotic inflation lie outside the WMAP 2-σbounds. We also find that r > 0.002, provided the scalar spectral index n_s > 0.96. In estimating the lower bound on r we take into account possible modifications due to quantum corrections of the tree level inflationary potential.

description: During the operational life of the Italian/Dutch X-ray satellite (1996-2002), BeppoSAX, its two Wide Field Cameras performed observations that covered the full sky at different epochs. Although the majority of analysis performed on BeppoSAX WFC data concentrated on the detection of transient sources, we have now applied the same techniques developed for the INTEGRAL/IBIS survey to produce the same work with the BeppoSAX WFC data. This work represents the first unbiased source list compilation produced from the overall WFC data set optimised for faint persistent sources detection. This approach recovers 182 more sources compared to the previous WFC catalogue reported in Verrecchia et al. (2007). The catalogue contains 404 sources detected between 3-17 keV, 10 of which are yet to be seen by the new generation of telescopes.

description: Spectral singularities are among generic mathematical features of complex scattering potentials. Physically they correspond to scattering states that behave like zero-width resonances. For a simple optical system, we show that a spectral singularity appears whenever the gain coefficient coincides with its threshold value and other parameters of the system are selected properly. We explore a concrete realization of spectral singularities for a typical semiconductor gain medium and propose a method of constructing a tunable laser that operates at threshold gain.

Investigating the effect of repair ratio in stepped scarf repaired CFRP laminates under compressive loading

Year: 2019

description: In this work the effectiveness of stepped repair to damaged fiber reinforced composite materials was investigated by using validated FE numerical models that compared with tested repaired composite plates. Attention was given at the actual failure modes of composites including delamination. All FE models took into account the anisotropy in each ply in the laminate and in the repair patch by splitting the laminates to sub laminates. This method was introduced in order to take into consideration the effect of delamination caused by the failure between the plies due to shear stresses. Parametric studies were carried out in order to compare forces, displacements, stresses and stiffness properties. Namely, models were analyzed depending on the overlap segment's length with repair scarf ratios varying from the value of 20 to the value 60 with a step increase of 10. The FE models allowed a direct comparison of the influence that the step length to ply thickness ratio had to the strength and stiffness restoration of the repaired composite structures.

description: We analyze the possibility to measure small thermal effects in the Casimir force between metal test bodies in configurations of a sphere above a plate and two parallel plates. For sphere-plate geometry used in many experiments we investigate the applicability of the proximity force approximation (PFA) to calculate thermal effects in the Casimir force and its gradient. It is shown that for real metals the two formulations of the PFA used in the literature lead to relative differences in the obtained results being less than a small parameter equal to the ratio of separation distance to sphere radius. For ideal metals the PFA results for the thermal correction are obtained and compared with available exact results. It is emphasized that in the experimental region in the zeroth order of the small parameter mentioned above the thermal Casimir force and its gradient calculated using the PFA (and thermal corrections in their own right) coincide with respective exact results. For real metals available exact results are outside the application region of the PFA. However, the exact results are shown to converge to the PFA results when the small parameter goes down to the experimental values. We arrive at the conclusion that large thermal effects predicted by the Drude model approach, if existing at all, could be measured in both static and dynamic experiments in sphere-plate and plate-plate configurations. As to the small thermal effects predicted by the plasma model approach, the static experiment in the configuration of two parallel plates is found to be the best for its observation.

description: Das „Clean Energy for All Europeans“-Pakets wird direkte Auswirkungen auf die Ausgestaltung möglicher Kapazitätsmechanismen (Capacity Mechanisms - CMs) in Europa haben. Auf Basis der bereits vorliegenden Informationen sind drei verschiedene Szenarien untersucht worden. Dabei ergibt sich für zwei Szenarien kein Kapazitätsbedarf, der die Einführung eines CMs rechtfertigt. In der Folge dürften CMs nicht verlängert werden und die Vergütung der betroffenen Kapazitätsbetreiber sollte auslaufen. Auch schließt der vorgeschriebene CO2-Grenzwert von voraussichtlich 550 g CO2/kWhel über 60 Prozent der thermischen Kraftwerke in Deutschland von einer Teilnahme an einem CM aus.

description: The objective of the study was to isolate fungi from healthy and wilt banana in order to understand their diversity as well as their physiological characters to produce growth hormone and solubilize inorganic phosphate. The fungi were isolated from the leaves, roots, and rhizosphere of the banana. As many 13 fungal isolates were associated with wilt banana, consisted of Fusarium, Trichoderma, Bipolaris, Colletotrichum, Clonostachys, and Talaromyces genus. On the other hand, 12 fungal isolates that belong to 10 genera related to the healthy banana have been isolated, including Trichoderma, Pallidocercospora, Purpureocillium, Pallidocercospora, Mycosphaerella, Chaetomium, Neonectria, Pararamichloridium, Xylaria, and Neocordana. We found that the fungal isolates associated with wilt banana, particularly from the Fusarium genus, actively produced IAA in the presence of exogenous L-Tryptophan have high ability to solubilize insoluble phosphate. The ability of fungal isolates to solubilize insoluble phosphate was correlated with their ability to acidify the medium.

description: The dynamics of pions and strange particles in heavy-ion collisions in the region of 1A GeV energies is investigated by the lanzhou quantum molecular dynamics model for probing the nuclear equation of state at supra-saturation densities. The total multiplicities and the ratios obtained in $^{197}$Au+$^{197}$Au over $^{12}$C+$^{12}$C systems are calculated for selected Skyrme parameters SkP, SLy6, Ska and SIII, which correspond to different modulus of incompressibility of symmetric nuclear matter and different cases of the stiffness of symmetry energy. A decrease trend of the excitation functions of the ratios for strange particle production with increasing incident energy was observed. The available data of K$^{+}$ production measured by KaoS collaboration are described well with the parameter SkP, which results in a soft equation of state. The conclusions can not be modified by an in-medium kaon-nucleon potential.

description: Callus like galls were observed inside the stem of more than 5-year old papaya trees in Kerala, India. The bacterium Pantoea dispersa and the fungus Fusarium spinosum were isolated from these galls. Identity of the fungus was confirmed by sequencing and analysis of rDNA region, EFα gene and phylogenetic and barcode analyses. Bacterial identity was confirmed by analysis of rDNA region. Pathogenicity tests with a combination of the fungus and bacterium and bacterium alone, resulted in gall formation. Individual inoculation of F. spinosum did not result in gall. Only P. dispersa was re-isolated from the galls, indicating its etiological role. Supplemental data for this article is available online at https://doi.org/10.1080/03235408.2021.1974686 .

description: We use high-resolution three-dimensional adaptive mesh refinement simulations to investigate the interaction of high-redshift galaxy outflows with low-mass virialized clouds of primordial composition. While atomic cooling allows star formation in objects with virial temperatures above $10^4$ K, "minihaloes" below this threshold are generally unable to form stars by themselves. However, these objects are highly susceptible to triggered star formation, induced by outflows from neighboring high-redshift starburst galaxies. Here we conduct a study of these interactions, focusing on cooling through non-equilibrium molecular hydrogen (H$_2$) and hydrogen deuteride (HD) formation. Tracking the non-equilibrium chemistry and cooling of 14 species and including the presence of a dissociating background, we show that shock interactions can transform minihaloes into extremely compact clusters of coeval stars. Furthermore, these clusters are all less than $\approx 10^6 M_\odot,$ and they are ejected from their parent dark matter halos: properties that are remarkably similar to those of the old population of globular clusters.

description: In the framework of simple spin-boson Hamiltonian we study an interplay between dynamic and spectral roots to stochastic-like behavior. The Hamiltonian describes an initial vibrational state coupled to discrete dense spectrum reservoir. The reservoir states are formed by three sequences with rationally independent periodicities typical for vibrational states in many nanosize systems. We show that quantum evolution of the system is determined by a dimensionless parameter which is characteristic number of the reservoir states relevant for the initial vibrational level dynamics. Our semi-quantitative analytic results are confirmed by numerical solution of the equation of motion. We anticipate that predicted in the paper both kinds of stochastic-like behavior (namely, due to spectral mixing and recurrence cycle dynamic mixing) can be observed by femtosecond spectroscopy methods in nanosystems.

The orbital period and system parameters of the recurrent nova T Pyx

description: T Pyx is a luminous recurrent nova that accretes at a much higher rate than is expected for its photometrically determined orbital period of about 1.8 hours. We here provide the first spectroscopic confirmation of the orbital period, P =1.829 hours (f=13.118368(11) c/d), based on time-resolved optical spectroscopy obtained at the VLT and the Magellan telescopes. We also derive an upper limit of the velocity semi-amplitude of the white dwarf, K1 = 17.9 +/- 1.6 km/s, and estimate a mass ratio of q = 0.20 +/- 0.03. If the mass of the donor star is estimated using the period-density relation and theoretical main-sequence mass-radius relation for a slightly inflated donor star, we find M2 = 0.14 +/- 0.03 Msun. This implies a mass of the primary white dwarf M1 = 0.7 +/- 0.2 Msun. If the white-dwarf mass is > 1 Msun, as classical nova models imply, the donor mass must be even higher. We therefore rule out the possibility that T Pyx has evolved beyond the period minimum for cataclysmic variables. We find that the system inclination is constrained to be approximately 10 degrees, confirming the expectation that T Pyx is a low-inclination system. We also discuss some of the evolutionary implications of the emerging physical picture of T Pyx. In particular, we show that epochs of enhanced mass transfer (like the present) may accelerate or even dominate the overall evolution of the system, even if they are relatively short-lived. We also point out that such phases may be relevant to the evolution of cataclysmic variables more generally.

description: We show that thin horizontal arrays of single wall carbon nanotubes (SWNTs) suspended above the channel of silicon MOSFETs can be used as vibrating gate electrodes. This new class of nano-electromechanical system (NEMS) combines the unique mechanical and electronic properties of SWNTs with an integrated siliconbased motion detection. Its electrical response exhibits a clear signature of the mechanical resonance of SWNTs arrays (120-150 MHz) showing that these thin horizontal arrays behave as a cohesive, rigid and elastic body membrane with a Young modulus in the order of 1-10 GPa and ultra-low mass. The resonant frequency can be tuned by the gate voltage and its dependence is well understood within the continuum mechanics framework.

description: Far-infrared diagonal and Hall conductivities of multilayer epitaxial graphene on the C-face of SiC were measured using magneto-optical absorption and Faraday rotation in magnetic fields up to 7 T and temperatures between 5 and 300 K. Multiple components are identified in the spectra, which include: (i) a quasi-classical cyclotron resonance (CR), originating from the highly doped graphene layer closest to SiC, (ii) transitions between low-index Landau levels (LLs), which stem from weakly doped layers and (iii) a broad optical absorption background. Electron and hole type LL transitions are optically distinguished and shown to coexist. An electron-hole asymmetry of the Fermi velocity of about 2% was found within one graphene layer, while the Fermi velocity varies by about 10% across the layers. The optical intensity of the LL transitions is several times smaller than what is theoretically expected for isolated graphene monolayers without electron-electron and electron-phonon interactions.

description: The Levi-Malcev decomposition is applied to bosonic models of quantum mechanics based on unitary Lie algebras u(2), u(2)+u(2), u(3) and u(4) to clearly disentangle semisimple subalgebras. The theory of weighted Dynkin diagrams is then applied to identify conjugacy classes of relevant A_1 subalgebras allowing to introduce a complete classification of new angular momentum non conserving (AMNC) dynamical symmetries. The tensor analysis of the whole algebra based on the new "angular momentum" operators reveals unexpected spinors to occur in purely bosonic models. The new chains of subalgebra can be invoked to set up ANMC bases for diagonalization.

description: Using the Feynman-Vdovichenko combinatorial approach to the two dimensional Ising model, we determine the exact Curie temperature for all two dimensional Archimedean lattices. By means of duality, we extend our results to cover all two dimensional Laves lattices. For those lattices where the exact critical temperatures are not exactly known yet, we compare them with Monte Carlo simulations.

Subjects: Key Performance Indicators, Technical, Economic, Environmental

description: In this deliverable, the Key Performance Indicators (KPIs) for the assessment of the different systems that will be developed along the project are described. Technical, economic and environmental KPIs have been defined, taking into account relevant European and international norms, as well as other recognized references.
 The purpose is to set a basis for evaluating different attributes, which set the technical performance, economic profitability and environmental performance of the systems which will be designed and demonstrated in TRI-HP project. The KPIs can be used as well for comparison of the developed systems in TRI-HP with reference cases. In that way, the compliance with the objective values can be evaluated.

Subjects: subject: Somalia

description: This policy brief examines justice and security in Somalia through the lens of fragmented peace-conflict spaces, drawing on the PeaceRep PA-X Local database analysis by Christine Bell and Laura Wise. Their research highlights how failed national peace processes have led to new sub-national dynamics of peace and conflict, necessitating more nuanced policy responses. Focusing on Kismayo and Galkayo, two key urban centers with distinct political and security landscapes, this brief explores their governance structures, justice mechanisms, and broader regional and transnational influences. Kismayo, under Jubbaland administration, exhibits centralised control with a structured security apparatus, whereas Galkayo remains a contested space requiring ongoing negotiation between Puntland and Galmudug authorities. Both towns also serve as strategic trade corridors, further shaping their justice and security dynamics. This brief, based on research conducted under PeaceRep Somalia and its predecessor, the Conflict Research Programme (CRP), underscores the importance of localised peace and security interventions. By understanding these fragmented spaces, policymakers can develop more effective strategies that go beyond elite-level settlements to foster sustainable stability and governance in Somalia.

description: This report analyses justice and security dynamics in Somalia through a comparative study of Kismayo and Galkayo, applying Bell and Wise’s (2022) framework on fragmented peace-conflict spaces. It examines how governance and security arrangements in these towns reflect broader Somali state formation processes. Kismayo, a key seaport under Jubbaland administration, operates as a territorially limited transcalar space with centralized governance shaped by Islamist influences and Al-Shabaab’s presence. The city has achieved relative stability and credible justice provision but faces challenges related to political exclusion. Galkayo, a divided town between Puntland and Galmudug, exemplifies a borderland mediation space where governance remains contested and security arrangements fluid, requiring ongoing negotiation among multiple actors. Despite a 2017 peace agreement, instability persists. Both towns also function as route-of-passage spaces, serving as trade corridors that influence justice and security. Their differing political orders underscore the need for localized, adaptive peace and security interventions. The study highlights the importance of tailoring strategies to specific governance dynamics while ensuring alignment with broader national peacebuilding efforts.

description: Massive evolved stars can produce large amounts of dust, and far-infrared (IR) data are essential for determining the contribution of cold dust to the total dust mass. Using Herschel, we search for cold dust in three very dusty massive evolved stars in the Large Magellanic Cloud: R71 is a Luminous Blue Variable, HD36402 is a Wolf-Rayet triple system, and IRAS05280-6910 is a red supergiant. We model the spectral energy distributions using radiative transfer codes and find that these three stars have mass-loss rates up to 10^-3 solar masses/year, suggesting that high-mass stars are important contributors to the life-cycle of dust. We found far-IR excesses in two objects, but these excesses appear to be associated with ISM and star-forming regions. Cold dust (T < 100 K) may thus not be an important contributor to the dust masses of evolved stars.

description: The TRI-HP H2020 project is aiming to develop trigeneration integrated solutions that combine heating, cooling and
 electricity generation, based on heat pumps with natural refrigerants and using multiple renewable heat sources.
 One of the economic goals is to reduce the installation cost of the complete system by 10 % to 15 %. In this deliverable,
 a rst economic assessment of the systems under development is presented, that is, the solar ice-slurry
 system and the dual source/sink system. The costs have been derived for the cases of Spain and Switzerland.
 On the one hand, the cost of the elements which are not under development in the project have been derived using
 recognized references, such as commercial information, quotation requests to well-known manufacturers, or other
 relevant references. On the other hand, the costs of the new developments of the project have been derived for
 each of the heat pump systems. In order to gather those data, the experimental research carried out until the
 date, as well as a prospective for future improvements for each of the new developments, have been taken into
 account.

Competing magnetic interactions in CeNi9-xCoxGe4

description: CeNi9Ge4 exhibits outstanding heavy fermion features with remarkable non-Fermi- liquid behavior which is mainly driven by single-ion effects. The substitution of Ni by Cu causes a reduction of both, the RKKY coupling and Kondo interaction, coming along with a dramatic change of the crystal field (CF) splitting. Thereby a quasi-quartet ground state observed in CeNi9Ge4 reduces to a two-fold degenerate one in CeNi8CuGe4. This leads to a modiffcation of the effective spin degeneracy of the Kondo lattice ground state and to the appearance of antiferromagnetic (AFM) order. To obtain a better understanding of consequences resulting from a reduction of the effective spin degeneracy, we stepwise replaced Ni by Co. Thereby an increase of the Kondo and RKKY interactions through the reduction of the effective d-electron count is expected. Accordingly, a paramagnetic Fermi liquid ground state should arise. Our experimental studies, however, reveal AFM order already for small Co concentrations, which becomes even more pronounced with increasing Co content x. Thereby the modiffcation of the effective spin degeneracy seems to play a crucial role in this system.
European government of crisis: Summary of the research findings in the four regimes and containing policy-relevant recommendations for the enhancement of crisis leadership capacity on the basis of the research

description: This study explores the way in which European governance seeks to address transboundary crises. Transboundary crises pose a particular challenge for administrative systems as costs and benefits are unevenly distributed, organisational and jurisdictional competencies over- and underlap, and as problem definitions and solutions are usually disputed. Boundaries are essential for the identity of national states, they are critical for determining the jurisdictional competence of organisations and they are critical for administering individual phenomena. Transboundary crises, in contrast, do not respect such boundaries. Crises themselves might be disruptive, but might be contained within certain boundaries. In the context of transboundary crises, disruption crosses jurisdictional boundaries. Furthermore, decisions in one place do not just affect the quality of the crises in that particular locality, they also affect the nature of the crisis in other jurisdictions. Transboundary crises are said to be of particular relevance to the contemporary context of governance as processes of globalisation have increased vulnerabilities to crises. Furthermore, the rise of multi-level and supra-national forms of governance reduces states’ ability to tackle crises within their own boundaries (Boin et al. 2013). In other words, transboundary crises present a central challenge to any contemporary system of governing. This study is particularly interested in the ways in which the EU as a system of multi-level governances organises crisis management regimes to address certain types of transboundary crises. The question of how the EU addresses transboundary crises has become increasingly pertinent since the financial crisis is said to have brought about a new era of ‘emergency politics’ (White 2015). The financial and sovereign debt crises highlighted the vulnerability of the EU and its member states to transboundary crises. It also highlighted the tensions that emerge from seeking to develop coordinated responses in the context of an integrating market that maintains an emphasis on national liberal democracy. More recent cases, such as the refugee and terrorism crises, have also exposed the difficulties in coordinating transboundary crises inside the European Union with member states that have diverging, if not conflicting, interests.

description: We investigate some properties of the nonequilibrium stationary state (NESS) of a one dimensional open system consisting of first and second class (type 1 and type 2) particles. The dynamics are totally asymmetric but the rates for the different permitted exchanges (10 -> 01, 12 -> 21, and 20 -> 02) need not be equal. The entrance and exit rates of the different species can also be different. We show that for certain classes of rates one can compute the currents and phase diagram, or at least obtain some monotonicity properties. For other classes one can obtain a matrix representation of the NESS; this generalizes previous work in which second class particles can neither enter nor leave the system. We analyze a simple example of this type and establish the existence of a randomly located shock at which the typical density profiles of all three species are discontinuous.
