description: An interesting manufacturing method to obtain in large scale chalcopyrite thin films is the two stage
process consisting of the evaporation of metallic precursor layers and the subsequent annealing in a selenium
environment. In the present work, thin films of chalcopyrite Cu(In,Al)Se2 (CIAS) were prepared by reaction of
elemental Se vapour with the sequentially evaporated metallic precursors onto soda-lime glass (SLG) substrate into a
quartz tube furnace, heating up to different temperatures in Ar atmosphere. Selenized samples at temperatures
ranging from 400ºC to 550ºC were characterized to study the dependence of the structural, optical and morphological
properties with the increase of the annealing temperature. An optimum temperature is searched, able to complete the
crystallization process but without exceeding the energy consumption. With this aim, the evolution of the reaction
and crystallization with the annealing temperature has been investigated for CIAS compound with x=0.4.
Selenization temperature was found to have significant influence on structure of the films.

description: We present an improved statistical method for calculation of mean lifetime of nuclei in a decay chain with uncertain relation between mother and daughter nuclei. The method is based on formation of time distribution of intervals between mother and daughter nuclei, without trying to set the exact mother-daughter nuclei relationship. If there is a coincidence of mother and daughter nuclei decays, sum of these distributions has flat term on which an exponential term is superimposed. Parameters of this exponential function allow lifetime of daughter nucleus to be extracted. The method is tested on Monte Carlo simulation data.

description: A consistent derivation of the equations of motion (EOMs) of test particles for solving the spin-dependent Boltzmann-Vlasov equation is presented. The resulting EOMs in phase space are similar to the canonical equations in Hamiltonian dynamics, and the EOM of spin is the same as that in the Heisenburg picture of quantum mechanics. Considering further the quantum nature of spin and choosing the direction of total angular momentum in heavy-ion reactions as a reference of measuring nucleon spin, the EOMs of spin-up and spin-down nucleons are given separately. The key elements affecting the spin dynamics in heavy-ion collisions are identified. The resulting EOMs provide a solid foundation for using the test-particle approach in studying spin dynamics in heavy-ion collisions at intermediate energies. Future comparisons of model simulations with experimental data will help constrain the poorly known in-medium nucleon spin-orbit coupling relevant for understanding properties of rare isotopes and their astrophysical impacts.

description: Cu(In,Ga)Se2 (CIGS) absorber films were deposited on Mo-coated polyimide sheet via lowtemperature
evaporation process. The material properties of Mo films and absorbers have been investigated by SEM
and XRD measurements. It was found that the Mo film exhibits higher resistivity after CIGS layer deposition and is
prone to cracking/peeling. To solving this problem, a thin SiO2 layer was deposited between polyimide substrate and
Mo film. And the results shown that it could play a role to minimize the cracks and reduce the resistivity of the Mo
back contact. Subsequently, the films were used to fabricate the corresponding solar cells with the total-area of 0.65
cm2. The CIGS solar cells with SiO2 layer exhibit better performance than those without SiO2 layer. A conversion
efficiency of about 9.15% has been obtained for the cell with such thin layer.

Now Myzomela rubratra asuncionis Salomonsen, 1966. See Pratt et al., 1987: 277, Dickinson, 2003: 442, and Higgins et al., 2008: 644–645. HOLOTYPE: AMNH 692934, unsexed [adult female], collected on Asuncion Island, 19.34N, 145.24E (Times Atlas), Commonwealth of Northern Mariana Islands, in June 1904, by Owston’s Japanese Collectors. From the Rothschild Collection. COMMENTS: In the original description, Salomonsen gave the AMNH number of the holotype, noting that the type was the only adult female ever collected. However, this specimen had not been sexed by the collector. He considered the range of asuncionis to be the Northern Mariana Islands of Asuncion, Agrihan, Pagan, and Alamagan. Without citing the number of male specimens he examined, Salomonsen said that the male differed from the male of the allied subspecies saffordi in having larger proportions. The only male paratype in AMNH is AMNH 692933, collected on Agrihan (Agrigan on label) in December 1888 by A. Marche (no. 5717). Specimens from Saipan were considered intermediate between saffordi and asuncionis by Salomonsen. Pratt et al. (1987: 277) omitted asuncionis, apparently including it in saffordi; Dickinson (2003: 442) and Higgins et al. (2008: 644) listed it without comment.

description: In this short note, we consider a system of two rotors, one of which interacts with a Langevin heat bath. We show that the system relaxes to its invariant measure (steady state) no faster than a stretched exponential $\exp(-c t^{1/2})$. This indicates that the exponent $1/2$ obtained earlier by the present authors and J.-P. Eckmann for short chains of rotors is optimal.

description: Worauf schon die Literatur hinweist, kann mit dieser Studie bestätigt werden: Eine langfristige metabolische Kontrolle stellt einen essentiellen Faktor in der adäquaten Betreuung von GDM Patientinnen dar. Dies wird nicht nur durch eine IGT bei einem Drittel der Probandinnen, sondern auch durch durchschnittlich höhere Insulin- und Kortisolspiegel 5,5 Jahre nach der Erkrankung bestätigt. Die Objektivierung einer psychiatrischen Beeinträchtigung oder Einschränkung neuropsychologischer Funktionen aufgrund einer persistierenden Hyperglykämie konnte nicht eindeutig bestätigt werden. In Gedächtnistests sowie im subjektiven psychischen und somatischen Befinden konnten nur tendenzielle Unterschiede gemessen werden. Dies gilt auch in Abhängigkeit von der metabolischen Kontrolle unabängig eines zu Grunde liegenden Gestationsdiabetes. Auch wenn die Studie keine kognitive Beeinträchtigung nachweisen konnte, sind Störungen durch langfristige metabolische Dysfunktionen nicht auszuschliessen. Bei der Durchführung weiterer derartiger Studien sind unbedingt die von uns einbezogenen Stoffwechselparameter (Kortisol, Insulin und Glukose) mit Einfluss auf die Kognition einzubeziehen. Ein regelmässiges Follow-Up der Schwangeren mit Gestationsdiabetes sollte in jedem Fall erfolgen, um einen postpartalen Typ-2-Diabetes mellitus rechtzeitig zu erkennen und therapieren zu können.
description: This study can confirm the importance of long term metabolic control in GDM Patients as the existing literature is already pointing out. It is an essential aspect in the adequate support of patients with gestational diabetes. It is shown not only by an impaired glucose tolerance in one third of GDM Patients but also by insuline and glucagon levels above average 5.5 Years after the concerning pregnancy. The objectification of psychiatric impairment or impairment in neuropsychological functions due to persistent hyperglycaemia could not be proved clearly. In memory tests as in psychological or somatic findings we could only measure tendencies without significant differences. This counts also for the metabolic control itself without the existence of preceding gestational diabetes. Even though there were no cognitive impairments proven, we could not exclude any disturbances due to long term metabolic dysfunction. With the execution of future studies, metabolic parameter that we used (Insulin, Glucagone, Glucose) should be included as influencing parameter to cognitive functions. A Follow Up in GDM Patients should be performed regularly in any case, not only to exclude the development of a possible diabetes mellitus.

We show the existence of unital special commutative $\dagger$-Frobenius algebras, and we conclude $^\star\!\operatorname{Hilb}$ to be compact closed, with partial traces and a Hilbert-Schmidt inner product on morphisms. We exemplify our techniques on the textbook case of 1-dimensional wavefunctions with periodic boundary conditions: we show the momentum and position observables to be well defined, and to give rise to a strongly complementary pair of unital commutative $\dagger$-Frobenius algebras.

description: As the word photovoltaic describes the light used to produce electricity, photovoltaic technology generates electricity from light. The greater the light intensity, the greater the flow of electricity, thus shading is critical. Minor shading can result in a significant energy reduction. Tilting the panel could definitely be a solution one might think! The tilting motion allows the build up of fine sand to be blown off from the array’s surface. However, gradually with time, dust particles tend to accumulate at the edges of the panel making it incredibly difficult to thereby simply float off by a passing breeze and thus affecting the overall efficiency of the solar panel, thus periodical cleaning of PV generators seems to be necessary. In this research work an original method to reduce the effect of wind blown sand and dust on photovoltaic arrays is described. The proposed method is based on the use of small DC fans that can be attached to the solar module and help in reducing the dust accumulation on the surface of the module, hence improving its efficiency.

These representations are symplectic of dimension $4$. Following a method of Dieulefait, we determine the primes $\ell$ for which these representations are absolutely irreducible. In addition, we show that their image is "full" for all primes $\ell$ such that the associated residual representation is absolutely irreducible, except in two cases.

title: Social media as facilitators of tacit knowledge sharing practices amongst public sector employees
Creators: name: Buunk, Iris
Publisher: name: Edinburgh Napier University
Year: 2020

description: This work is concerned with the exploration of social technologies relevant to the sharing of tacit knowledge within the public sector. The findings derive from analysis of empirical data collected via survey research and twenty qualitative interviews with the members of an online knowledge sharing platform dedicated to those working within public sector bodies, mainly in Scotland.
The main contribution of the thesis is that it extends understanding of how social technologies render tacit knowledge visible by 1) providing access to online interactions for geographically dispersed individuals, 2) storing online social interactions, making them reusable, and 3) increasing network growth. The visibility of such tacit knowledge enhances knowledge awareness. This contributes to collective intelligence and learning processes and enables new collaborations.
The concept of Ba, a Japanese concept from 1998 that emphasises the influence that contexts can have over the sharing of tacit knowledge is updated with respect to the use of social media tools.
These two contributions are significant because previous research in Knowledge Management has not extensively investigated the ways in which social technologies contribute to the sharing of tacit knowledge within the public sector. They also emphasise the added value of social media tools with respect to the visibility of tacit knowledge and add a further valuable dimension to a well-known model that is frequently cited in the Knowledge Management literature.
Die Bedeutung der praepositio für den Handelsverkehr im antiken Rom

description: Die praepositio als einseitiger Rechtsakt, mit dem ein Unternehmer eine Person zum selbständigen Abschluss von Verträgen und zur Durchführung von Rechtsgeschäften einsetzte, den Geschäftskreis des Angestellten absteckte und sich verpflichtete, in diesem Rahmen für dessen Verpflichtungen wie für eigene einzustehen, war ein wichtiger Bestandteil im Wirtschaftslebens des antiken Rom. Sie überbrückte die Lücke, die sich aus der wirtschaftlichen Notwendigkeit ergeben hatte, bei zunehmend arbeitsteiliger Wirtschaft denjenigen direkt verpflichten zu können, dessen Geschäfte geführt wurden, und der noch fehlenden direkten Stellvertretung. Sie bot dem jeweiligen Handelspartner die für Geschäftsabschlüsse notwendige Sicherheit, berechtigte Forderungen auch durchsetzen zu können, dem Unternehmer die Möglichkeit, durch Beschreibung des Geschäftskreises seines Angestellten Unternehmensziele zu definieren aber auch die eigene Haftung zu begrenzen, und dem Angestellten die Gewissheit, dass der Unternehmer für Verpflichtungen aus den von ihm im Rahmen seiner Befugnisse abgeschlossenen Rechtsgeschäften mit einstehen würde. Die praepositio hat damit wesentlich zur Fortbildung des Rechts beigetragen, indem sie die stark obligationenrechtliche Bindung der Vertragsparteien langsam aufgelöst und damit den Weg zur direkten Stellvertretung geebnet hat.
description: Praepositio was the unilateral act by a businessman granting authority to an employee. This act gave authority to the latter to conclude and execute contracts with third parties. It described the area of accountability of the employee’s activity and engaged the businessman to answer for the obligations concluded by his employee. Praepositio thus bridged the gap between the necessity to act on behalf of another person and the rules of agency which did not yet exist in the modern understanding. Thus, it played an important role in the economic life of Ancient Rome. Praepositio provided a third party the assurance that, in the end, his contractual claims will be honoured. At the same time, the businessman was enabled to define the goals of his enterprise and to limit his own responsibility. Finally, the employee had the necessary assurance that the businessman will honour the obligations which were concluded within the limits described by the praepositio. Hence, the praepositio was an important step towards the suspension of the strict person-to-person relationship of the Roman law and towards agency in the modern understanding.

Balance of System Components

description: 23rd European Photovoltaic Solar Energy Conference and Exhibition, 1-5 September 2008, Valencia, Spain; 3016-3019
description: In this paper, a simple control scheme using input voltage balancing control concept and novel topology are presented for grid-connected photovoltaic power conditioning system. A three-loop control scheme, including a dedicated input voltage controller is proposed to achieve equal sharing of the input as well output voltages by series connected modules. This control scheme minimizes the interaction among the various control loops. The input-series connection enables a fully modular power-system architecture, where low voltage and low power modules can be connected in any given specification, further, input-series connection enables the use of lowvoltage
MOSFETs that are optimized for very low RDS ON, thus, resulting in lower conduction losses. The proposed topology for PV PCS can dramatically reduce the converter power ratings and increase the efficiency of total PV
PCS system. According to analysis of PV characteristics, in proposed topology, only 33.3% power of total PV system power is needed for DC/DC converter. DC/DC converter used in proposed topology has flat efficiency curve throughout all load range and very high efficiency characteristics. The total PV PCS efficiency is the product of that of converter and that of inverter. In propose topology, because the converter efficiency curve is flat throughout all load range, the total system efficiency at the low power range is dramatically improved. The proposed topology is implemented for 250kW PCS system. This system has only three DC/DC converters with 25kW power rating each other. It is only one-third of total system power. The experiment results show that the proposed input voltage balancing control algorithm, and design of novel topology have good performances.

description: We prepared a Cu2ZnSn(SxSe1-x)4 (CZTSSe) solid solution with 0 ≤ x ≤ 1.0. The CZTSSe solid
solution powders were synthesized by heating the elemental mixtures at 550oC for 5 h in an N2 gas atmosphere. The
crystal structure was analyzed on the basis of tetragonal kesterite-type crystal structure by Rietveld refinement of Xray
diffraction data. The lattice parameters, a and c, monotonically decreased with increasing S content. Then we
fabricated CZTSSe films by a printing and high-pressure sintering (PHS) process. First, we prepared CZTSSe ink by
mixing a CZTSSe powder and organic solvent. A particulate precursor layer was deposited on a substrate by screen
printing, and the porous precursor layer was sintered into a dense polycrystalline film by high pressure sintering in an
N2 gas atmosphere. The obtained CZTSSe film was post-annealed at 600oC for 10 min in an N2 gas atmosphere. The
microstructures of the CZTSSe film were observed in an SEM. The optical properties of the CZTSSe film were
characterized by NIR-VIS-UV-spectroscopy. The band gap energy (Eg) of CZTSSe was determined from the
transmittance and diffuse reflectance data. The Eg of the Cu2ZnSn(SxSe1-x)4 solid solution monotonically increased
from 1.05 eV for CZTSe to 1.51 eV for CZTS.

description: (Abridged) We make use of the deepest VLT/MUSE observations performed so far on the Hubble Deep Field South (HDFS) to characterize the low-mass (< $10^{10}$M$_\odot$) galaxy population at intermediate redshift. We identify a sample of 28 spatially-resolved emission-line galaxies in the deep (27h integration time) MUSE data cube, spread over a redshift interval of 0.2 < z < 1.4. The public HST images and multi-band photometry over the HDFS are used to constrain the stellar mass and star formation rate (SFR) of the galaxies and to perform a morphological analysis. We derive the resolved ionized gas properties of these galaxies from the MUSE data and model the disk (both in 2D and with GalPaK$^{\rm 3D}$) to retrieve their intrinsic gas kinematics. We build a sample of resolved emission-line galaxies of much lower stellar mass and SFR (by $\sim$1-2 orders of magnitude) than previous 3D spectroscopic surveys. Most of the spatially-resolved MUSE-HDFS galaxies have gas kinematics consistent with disk-like rotation, but about 20% have velocity dispersions larger than the rotation velocities, and 30% are part of a close pair and/or show clear signs of recent gravitational interactions. In the high-mass regime, the MUSE-HDFS galaxies follow the Tully-Fisher relation defined from previous surveys in a similar redshift range. This scaling relation extends also to lower masses/velocities but with a higher dispersion. The MUSE-HDFS galaxies follow the scaling relations defined in the local universe between the specific angular momentum and the stellar mass. However, we find that intermediate-redshift star-forming galaxies fill a continuum transition from the spiral to elliptical local scaling relations, according to the dynamical state of the gas. This indicates that some galaxies may lose their angular momentum and become dispersion-dominated prior to becoming passive.

While electrical measurements of PV generators in operating PV plants are often very extensive, IR imaging gives a fast and effective method to find defects in PV modules. Daily profiles with one minute I-V curve measurements of different PV modules with thermal phenomena were done under outdoor conditions. Additionally continuous IR imaging and meteorological data sampling was realized.

description: Micro-grid configurations are gaining as an alternative to grid-connect power supply in developing
countries. There are similar points of consideration and lessions to be learned from case studies. The authors have had
various engagements with developing countries providing analysis for micro-grid installation as well as visits to specific
sites. A cost-effective micro-grid for localized energy production must provide the correct mix of energy, and must be
maintained and expanded by the local community. There are four primary point of note for the implementation of this
micro-grid: (1) configured as a hybrid of standard and renewable energy - evolving towards more of the latter with time
(2) low cost and flexible - targeted to each communities needs, (3) follows the “cell-phone” model where a fixed, costly
infrastructure is not needed, (4) engages the community to participate and have “ownership” in the infrastructure. A site
visit to micro-grid applications in Cuba is used as a representative example. A key finding is the need for a strong,
strategic view of energy development to enable the growth of micro-grid power supply. The key common needs and
“best practices” are established to identify the optimal mode for addressing micro-grid implementation.
title: Beach leisure lifestyles and mobilities along Lebanese shores: unveiling complexities, particularities and intricacies
Creators: name: Adeimi, Jihane

description: This research explores the differentiated beach leisure lifestyles and mobilities of local beach goers in Lebanon belonging to different ethno-religious communities. Following the interpretivist/constructivist paradigm, this study is the first of its kind to primarily examine the complex synergy between gender, race, lifestyle, power relations, mental constructions and beach geographies, exposing the various forces at play behind the beach leisure dynamics in Lebanon. Beach leisure is rediscovered from the point of view of ‘what is escaped’, ‘what is avoided’, ‘what is hidden’, ‘what is overlooked’, ‘what is silenced’, bringing to the fore a different perspective and a less known, quite ‘darker’, side of beach leisure in Lebanon. In terms of research design, a case study approach has been adopted, using two qualitative research methods, namely in-depth interviews and participant observation (personal accounts), with the aim to report various ‘voices’ on the ground as well as personally experience local beaches with an autoethnographic lens. Research findings have revealed a hybrid and liquid seaside, made up of racialised, gendered, sexualised, politicised, ‘religioused’, classed and lifestylised Lebanese beaches. These findings shed light on how these beaches and practices are being represented, experienced, performed, navigated and negotiated by locals and how these complex beach leisure dynamics are reflecting the complexities and particularities of Lebanese society and the contradictions found within it. It is concluded that understanding these beach leisure dynamics can, possibly, push us to restructure some of our mental constructions, reconsider our own perceptions, question our taken-for-granted knowledge, as well as redefining our understanding of ‘Lebaneseness’.

description: Global radiation short time forecast of three different models (ECMWF, NDFD and GFS/WRF) have been compared. The comparison was made for a half year period (summer 2007) at three different climates in the USA. ECMWF shows the best results, followed by NDFD and GFS/WRF. Uncertainty varies strongly from place to place. At Desert Rock NV all models have an uncertainty of 18%. The biggest uncertainty is seen with GFS/WRF model at Boulder CO (50%). The breakeven with persistence is reached after 2-3 hours. Distributions of hourly
values do differ from measured values, but are quite similar to global radiation data based on satellite data.

description: We study a Monte Carlo algorithm that is based on a specific (randomly shifted and dilated) lattice point set. The main result of this paper is that the mean squared error for a given compactly supported, square-integrable function is bounded by $n^{-1/2}$ times the $L_2$-norm of the Fourier transform outside a region around the origin, where $n$ is the expected number of function evaluations. As corollaries we obtain the optimal order of convergence for functions from the Sobolev spaces $H^s_p$ with isotropic, anisotropic, or mixed smoothness with given compact support for all values of the parameters. If the region of integration is the unit cube, we obtain the same optimal orders for functions without boundary conditions. This proves, in particular, that the optimal order of convergence in the latter case is $n^{-s-1/2}$ for $p\ge2$, which is, in contrast to the case of deterministic algorithms, independent of the dimension. This shows that Monte Carlo algorithms can improve the order by more than $n^{-1/2}$ for a whole class of natural function spaces.

title: Mode choice modelling using elements of MINDSPACE and structural equation modelling
Creators: name: Ababio-Donkor, Augustus

description: The last two decades have witnessed a rising research interest in integrated choice and latent variable (ICLV) modelling, in direct response to the inability of the traditional choice models to adequately explain the over half a century growing trend of vehicular traffic in cities around the world. With little variations, several researchers in transport choice behaviour have suggested that the theory behind the traditional choice models do not sufficiently account for the heterogeneity of human behaviour and observed choice preferences. Literature is replete with evidence suggesting that attitudes and perceptions significantly influence decision-making. The challenge for researchers is understanding the attitude with the most significant impact to include in the hybrid choice models.
Interestingly, recent literature on consumer behaviour suggests that MINDSPACE have a significant impact on behaviour. MINDSPACE is the mnemonic for Messenger, Incentive, Norms, Default, Salience, Priming, Affect, Commitment, and Ego, these behavioural effects are believed to offer robust way of analysing and influencing behaviour.
This study, therefore, exploits the potential benefits of these two new research areas to develop MINDSPACE enriched ICLV model to explain the underlying transport mode choice behaviour of the population of Edinburgh using five hundred responses collected in a mail-back revealed preference survey. The proposed model integrates variables from the MINDSPACE framework as latent variables in the ICLV model. The study found strong evidence aside the socio-demographic and mode specific variables that Norm, Salience, and Affect have a significant influence on transport mode choice, among others. Overall, the ICLV model demonstrates considerable improvement over a reference logit model. The study could prompt policy development toward urban transportation because the findings have broader policy implication for public transport and travel behaviour change.

description: Hydrogenated amorphous silicon/ CZ silicon heterojunction solar cells are fabricated by plasma
enhanced chemical vapour deposition using an entirely low temperature process. Rear side deposition parameters, i.e.
dopant gas phase concentration, depositon time, and silane dilution in hydrogen, are varied. Cell current-voltage
characteristics under illumination, evidenced that a decrease of phosphine dilution in silane results in higher opencircuit
voltage, due to lower defect concentration associated to lower doping. Furthermore, layer thickness is
increased either by increasing deposition time or by increasing the silane/hydrogen ratio. In both cases, higher opencircuit
voltage is obtained with thicker n+ layer, due to shift of the Fermi level towards the bulk value. In the case of
high silane/hydrogen ratio, the amorphous to microcrystalline fraction of the rear layer is higher, thus partly acting as
a back surface field.

description: This paper investigates the recent stellar merger transient M31LRN 2015 in the Andromeda galaxy. We analyze published optical photometry and spectroscopy along with a Hubble Space Telescope detection of the color and magnitude of the pre-outburst source. The transient outburst is consistent with dynamically driven ejecta at the onset of a common envelope episode, which eventually leads to the complete merger of a binary system. The light curve appears to contain two components: first $\sim10^{-2} M_\odot$ of fast ejecta driven by shocks at the onset of common envelope, and later, $\sim0.3 M_\odot$ of further ejecta as the secondary becomes more deeply engulfed within the primary. Just prior to merger, we find that the primary star is a $3-5.5 M_\odot$ sub-giant branch primary star with radius of $30-40R_\odot$. Its position in the color-magnitude diagram shows that it is growing in radius, consistent with a picture where it engulfs its companion. By matching the properties of the primary star to the transient outburst, we show that the optical transient lasts less than ten orbits of the original binary, which had a pre-merger period of $\sim 10$ days. We consider the possible orbital dynamics leading up to the merger, and argue that if the system merged due to the Darwin tidal instability it implies a lower mass main sequence companion of $0.1-0.6M_\odot$. This analysis represents a promising step toward a more detailed understanding of flows in common envelope episodes through direct observational constraints.

title: Towards a unified method to synthesising scenarios and solvers in combinatorial optimisation via graph-based approaches
Creators: name: Stone, Christopher Luciano
Publisher: name: Edinburgh Napier University

description: Hyper-heuristics is a collection of search methods for selecting, combining and generating heuristics used to solve combinatorial optimisation problems. The primary objective of hyper-heuristics research is to develop more generally applicable search procedures that can be easily applied to a wide variety of problems. However, current hyper-heuristic architectures assume the existence of a domain barrier that does not allow low-level heuristics or operators to be applied outside their designed problem domain. Additionally the representation used to encode solvers diﬀers from the one used to encode solutions. This means that hyper-heuristic internal components can not be optimised by the system itself. In this thesis we address these issues by using graph reformulations of selected problems and search in the space of operators by using Grammatical Evolution techniques to evolve new perturbative and constructive heuristics. The low-level heuristics (representing graph transformations) are evolved using a single grammar which is capable of adapting to multiple domains. We test our generators of heuristics on instances of the Travelling Salesman Problem, Knapsack Problem and Load Balancing Problem and show that the best evolved heuristics can compete with human written heuristics and representations designed for each problem domain. Further we propose a conceptual framework for the production and combination of graph structures. We show how these concepts can be used to describe and provide a representation for problems in combinatorics and the inner mechanics of hyper-heuristic systems. The ﬁnal contribution is a new benchmark that can generate problem instances for multiple problem domains that can be used for the assessment of multi-domain problem solvers.

description: Complex intermetallic materials known as MAX phases exhibit exceptional properties from both metals and ceramics, largely thanks to their nanolayered structure. With high-resolution scanning transmission electron microscopy supported by atomistic modelling, we reveal atomic features of a nano-twist phase in the nanolayered \MAX. The rotated hexagonal single-crystal is encompassed within basal symmetric twist interfaces similar to grain boundaries. In particular, we show that air-oxidation at \SI{1000}{\celsius} can form a twisted phase that leads to the formation of interfacial dislocation networks with screw characters or to severe interfacial reconstructions. Additionally, we explore the contribution of disclinations to the representation by continuum models of the stress field generated by such nano-twist defect in the \MAX{} bulk phase. The occurrence of this unexpected defect is expected to impact the physical response of this nanolayered-based material as such supports property-by-design approaches.

description: This paper describes the development of a novel islanding detection method, which uses the signal cross-correlation scheme between the injected reactive current and the power frequency deviation. The existing method, which injects the reactive current of 2.5~5% to the rated current and detects the frequency deviation directly, brings about aggravating the power quality due to the harmonic pollution. The proposed method eliminates the weak point of the existing method, because it injects the reactive current less than 1% to the rated current. The operational feasibility was verified through computer simulations with PSCAD/EMTDC software, and experimental works with a 10kVA hardware prototype. The proposed method can detect the islanding status effectively without lowering the power quality of interconnected distributed generation system.
