description: The computer aided design process of sophisticated UHF-RFID transponder antennas requires the application of reliable simulation software. This paper describes a Matlab implemented extension of the post processor capabilities of the commercially available three dimensional field simulation programme Ansoft HFSS to compute an accurate solution of the antenna's surface current distribution. The accuracy of the simulated surface currents, which are physically related to the impedance at the feeding point of the antenna, depends on the convergence of the electromagnetic fields inside the simulation volume. The introduced method estimates the overall quality of the simulation results by combining the surface currents with the electromagnetic fields extracted from the field solution of Ansoft HFSS.

description: Products or semi-finished products featuring tailored properties are highly relevant for many industrial applications. Hence, new technologies that allow to locally adapt mechanical properties are of key interest. For example, tailoring properties in profiles or tubes by a local heat-treatment appear to be promising in combination with subsequent forming operations requiring locally adapted material strength to realize complex shapes. To implement an inline process of tube forming and local heat treatment by inductive heating and spray quenching, dilatometric investigations were carried out for a heat treatable boron-alloyed steel 1.5528 (22MnB5). In particular, focus was on the effect of high inductive heating rates on the austenite formation. The influence of heating rates in the range from 500 K/s to 2500 K/s on the austenitization was evaluated and a continuous time-temperature-austenitization diagram proposed. The results can be used to compute the decomposition of ferrite and pearlite due to inductive heating.

description: Rural areas represent an indigenous culture and richness of a native society. The environment made by this society is a product of local culture, built by the use of available local materials, considering local production and lifestyle of the villages. Continuity of rural areas is necessary for safeguarding a specific landscape – which has specific features – on earth with its components. A specific landscape can sustain only with a continuous rural life. For a sustainable rural life, the income source of the inhabitants which is mainly based on production should be continuous.

In Turkey, in rural areas, most of the population used to deal with the agricultural production. However, the number of people living in rural areas has decreased gradually because of the policies applied as a result of the worldwide movements and trends such as industrialization, mechanization, modernization and globalization. These policies affects the national policies and rural areas lost importance and improvement of urban areas become the foremost aim of the state. The outcomes of the changes in national policies threatens rural heritage achieving a positive contemporary transformation.

In this text, the transformation of rural areas in Turkey regarding the applied policies by the government is introduced to understand basics of the problem for conservation of rural areas. The alterations in the agricultural, legal and administrative policies in Turkey are discussed. The regulations made in the policies caused traditional rural practices of small land owners lost their validity by elimination of human force and discovery of new cultivation methods. The common crisis has been the unavoidable migration from rural to urban. This initiated improvisation of the peasants and annihilation of rural life and architecture. This process is also seen in rural areas of foreign countries and discussed on global platforms. Therefore, a general approach for conservation of rural areas is put forward through international charters comparing it with the approaches in Turkey.

description: The paper deals with an empirical validation of a building thermal model. We put the emphasis on sensitivity analysis and on research of inputs/residual correlation to improve our model. In this article, we apply a sensitivity analysis technique in the frequency domain to point out the more important parameters of the model. Then, we compare measured and predicted data of indoor dry-air temperature. When the model is not accurate enough, recourse to time-frequency analysis is of great help to identify the inputs responsible for the major part of error. In our approach, two samples of experimental data are required. The first one is used to calibrate our model the second one to really validate the optimized model.

description: Semiconductor-metal nanowire heterostructures have attracted a particular interest over the last decade. However, they often suffer from low interface and crystalline quality. Here, we present a model for the formation of GaAs-Au axial nanowire heterostructures from GaAs/Au core-shell nanowires encapsulated into SiO2 under flash lamp annealing, as described in the previous work. The model reveals the basic mechanism and establishes the main control parameters of the process which enable high quality GaAs-Au heterostructures. It can also be used for the optimization of similar processes in a wide range of material combinations.

description: Parameters  of  Morse potentials  for  describing  the  interactions  of  atoms  of  light  elements  C,  N,  O  with  atoms  of  fcc metals  Al,  Ag,  Ni  are  found. This  set  of  three  metals  is  unique  in  that  two  of  them  have  almost  the  same  radii  of  atoms,  while  the  other  two  have  almost  identical  electronegativities.  The  search  for  potential  parameters  was  carried  out  according to the empirical relationships observed for a large number of metals having C, N or O  impurities.  For  this  purpose,  the  most  studied  characteristics  were  chosen:  the  melting  or  decomposition  temperature  of  the  corresponding  chemical  compound  of  the  metal  with  the light element and the activation energy of diffusion of the impurity atom in the crystal lattice of  the  metal.  In  the    paper,  in  addition,  we  have  corrected  the  potentials  found  earlier  to  describe interatomic interactions in Pd-H and Ni-H systems.

description: Digitalization is changing industrial production and is offering huge potential for producing companies. One effect resulting from the increasing presence of information and communication technology in production is the increasing quantity and quality of production feedback data. However, only collecting large amounts of data of data does not lead to high logistical performance and low logistical costs. It is essential to acquire the right data with as little operating expenses as possible, to analyze the acquired data target-oriented and to present the results user-oriented, so that concrete actions can be derived. In practice, this is a challenge for producing companies. To demonstrate the opportunities in this field of action, a concept was developed at the Institute of Production Systems and Logistics (IFA) (Hannover, Germany) and, furthermore, implemented in the IFA learning factory. This paper starts with a short introduction of the IFA learning factory. After that, the paper presents the developed concept in detail, describing the PPC system, the data acquisition using RFID, an order processing support system using ESL and the (real-time) data analysis. In the end a summarizing conclusion is given underlining the importance of an integrated concept for data acquisition and utilization.

description: Spike-wave discharges (SWD) are electroencephalographic hallmarks of absence epilepsy. SWD are known to originate from thalamo-cortical neuronal network that normally produce sleep spindle oscillations. Although both sleep spindles and SWD are considered as thalamo-cortical oscillations, functional relationship between them is still uncertain. The present study describes temporal dynamics of SWD and sleep spindles as determined in long-term EEG recordings in WAG/Rij rat model of absence epilepsy. It was found that non-linear dynamics of SWD fits well to the law of 'on-off intermittency'. Typical sleep spindles that occur during slow-wave sleep (SWS) also demonstrated 'on-off intermittency' behavior, in contrast to high-voltage spindles during intermediate sleep stage, whose dynamics was uncertain. This implies that both SWS sleep spindles and SWD are controlled by a system-level mechanism that is responsible for regulating circadian activity and/or sleep-wake transitions.

description: The role of nuclear spin fluctuations in the dynamic polarization of nuclear spins by electrons is investigated in (In,Ga)As quantum dots. The photoluminescence polarization under circularly polarized optical pumping in transverse magnetic fields (Hanle effect) is studied. A weak additional magnetic field parallel to the optical axis is used to control the efficiency of nuclear spin cooling and the sign of nuclear spin temperature. The shape of the Hanle curve is drastically modified with changing this control field, as observed earlier in bulk semiconductors and quantum wells. However, the standard nuclear spin cooling theory, operating with the mean nuclear magnetic field (Overhauser field), fails to describe the experimental Hanle curves in a certain range of control fields. This controversy is resolved by taking into account the nuclear spin fluctuations owed to the finite number of nuclei in the quantum dot. We propose a model describing cooling of the nuclear spin system by electron spins experiencing fast vector precession in the random Overhauser fields of nuclear spin fluctuations. The model allows us to accurately describe the measured Hanle curves and to determine the parameters of the electron-nuclear spin system of the studied quantum dots.

description: Polycrystalline phosphor film Cd(1-x-y-z) (CuyAgz) ZnxS was grown on the surface of the Si/nano-SiC heterostructure obtained by the unique method of substitution of atoms. The structural, phonon (vibrational) properties of the film, as well as its morphology were studied. X-ray phase analysis (XRD) showed that the phase composition is represented by a matrix of solid  solution  of  cubic  syngony  and  impurity  phases  formed  during  precipitation:  sodium  sulfate  (Na2SO4)  of orthorhombic  syngony  and  sodium  cadmium  sulfide  (Na6Cd7S10)  of monoclinic syngony. The Raman spectroscopy (RS) method confirmed the components of the polycrystalline  phosphor  film,  including  its  phase  composition,  determined  by  the  X-ray phase analysis method.

description: We evaluate industrial-type PERC solar cells applying a dual printed front grid with stencil printed Ag fingers. We vary the Ag paste consumption for the finger print between 8.4 mg and 120.4 mg per 156 x 156 mm(2) wafer (weighted after printing before drying) by using polyurethane squeegees with different shore hardness as well as a metal squeegee and by varying the printing pressure to obtain different finger heights. The busbar consumes additional 19.5 mg Ag paste. We obtain average finger heights from 5.9 mu m up to 24.3 mu m for 55 mu m to 65 mu m wide fingers. The resulting PERC solar cells show an average efficiency of 20.2% for finger paste consumptions above 60 mg. In contrast, a strong reduction of the conversion efficiency with less than 60 mg finger paste consumption is observed since the increased series resistance reduces the FF. By analytical modelling, we compare the calculated series resistance to the experimental data and observe a good accordance for more than 40 mg finger paste consumption whereas the experimental series resistance slightly exceed the modelled values below 40 mg. In addition, we use numerical simulations to investigate the series resistance dependence on the finger height which shows higher experimental values for finger height below 10 mu m. The deviation of the measured series resistance and the two modelled cases is mostly due to inhomogeneous distribution of finger height profiles and finger interruptions on the solar cells with front finger paste consumption of less than 40 mg. For finger paste consumption below 60 mg, we find that also the specific contact resistance increases. A physical model of the root cause for this dependence still has to be found.

description: The main goal of this paper is to evaluate the possibility of application or replacement of radiators with low-temperature radiant panels. This paper shows the comparison results of operations of 4 space heating systems: the low-temperature radiant panel system without any additional thermal insulation of external walls (PH-WOI), the low-temperature radiant panel system with additional thermal insulation of external walls (PH-WI), the radiator system without any additional thermal insulation of external walls (the classical heating system) (RH-WOI), and the radiator system with additional thermal insulation of external walls (RH-WI). The operation of each system is simulated by software EnergyPlus. The investigation shows that the PH-WI gives the best results. The RH-WOI has the largest energy consumption, and the largest pollutant emission. However, the PH-WI requires the highest investment.

description: In the present Letter we show that the concept of the generalized synchronization regime in discrete maps needs refining in the same way as it has been done for the flow systems [PRE, 84 (2011) 037201]. We have shown that\alkor{, in the general case, when the relationship between state vectors of the interacting chaotic maps are considered,} the prehistory must be taken into account. We extend the phase tube approach to the systems with a discrete time coupled both unidirectionally and mutually and analyze the essence of the generalized synchronization by means of this technique. Obtained results show that the division of the generalized synchronization into the weak and the strong ones also must be reconsidered. Unidirectionally coupled logistic maps and Hénon maps coupled mutually are used as sample systems.

description: Based on a combined analysis of spectroscopic ellipsometry, reflectance and transmittance measurements as well as spectrally resolved luminescence measurements and spectral responsivity measurements, we present data of the coefficient of band-to-band absorption of crystalline silicon at 295 K in the wavelength range 250 - 1450 nm. A systematic measurement uncertainty analysis according to the "Guide to the Expression of Uncertainty in Measurements" (GUM) is carried out for each method, showing that the relative uncertainty of the absorption coefficient data so determined is of the order of 0.3% at 300 nm, 1% at 900 nm, 10% at 1200 nm and 180% at 1450 nm. The data are consolidated by comparison of measurements carried out independently at different institutions. The uncertainty of solar cell energy conversion predictions by means of simulations due to the uncertainty of the absorption coefficient data is shown to be of the order of 0.1% relative.

description: Cosmic rays with energy exceeding ~ 10^{18} eV are referred to as ultra-high energy cosmic rays (UHECRs). Monte Carlo codes for extensive air shower (EAS) simulate the development of EASs initiated by UHECRs in the Earth's atmosphere. Experiments to detect UHECRs utilize EAS simulations to estimate their energy, arrival direction, and composition. In this paper, we compare EAS simulations with two different codes, CORSIKA and COSMOS, presenting quantities including the longitudinal distribution of particles, depth of shower maximum, kinetic energy distribution of particle at the ground, and energy deposited to the air. We then discuss implications of our results to UHECR experiments.

description: Fermi has detected over 200 pulsars above 100 MeV. In a previous work, using 3 years of LAT data (1FHL catalog) we reported that 28 of these pulsars show emission above 10 GeV; only three of these, however, were millisecond pulsars (MSPs). The recently-released Third Catalog of Hard Fermi- LAT Sources (3FHL) contains over 1500 sources showing emission above 10 GeV, 17 of which are associated with gamma-ray MSPs. Using three times as much data as in our previous study (1FHL), we report on a systematic analysis of these pulsars to determine the highest energy (pulsed) emission from MSPs and discuss the best possible candidates for follow-up observations with ground-based TeV instruments (H.E.S.S., MAGIC, VERITAS, and the upcoming CTA). © Copyright owned by the author(s).

description: The fill factor determined from a measured current-voltage characteristic of a bare solar cell depends on the number and positions of the electrical contacting probes. Nine different geometries for contacting the front side busbars are used to measure the current-voltage (I-V) characteristics of a 5 busbar industrial-type passivated emitter and rear totally diffused (PERT) solar cell under standard testing conditions. The fill factors of the measured I-V characteristics vary from 78.5 %abs to 80.6 %abs. We further measure the contacting resistance of 3 different contacting probes to estimate the sensitivity of measurements with different contacting geometries on random resistance variations. The contacting resistance is 60 mΩ for nine-point probes and 80 mΩ for four- and single-point probes. We determine the magnitude of contacting resistance variations from measurements at different probe positions to be ±30 mΩ. Using this variation, we perform numerical simulations and find a larger sensitivity on random resistance variations for tandem- (pairs of current- and sense probes) compared to triplet (one sense- between two current probes) configurations. The corresponding fill factor deviation is approximately 0.1%abs for tandem configurations when the contacting resistances of up to two current probes are altered. The sensitivity for triplet configurations is negligible.

description: Islands with traditional villages and rural landscapes are major attractors to tourism. The heritage, local products and cultural landscapes are a significant part of the draw of visitors. However, it is these aspects of the island that, even if they are formally protected, often suffer from the high demands of tourism. Add the threats of climate change and you have places that suffer from unexpected interference with a way of life and a disturbance of a long lasting balance of human-nature relationships. Four themes run through the three papers and will be discussed from different angles – that of a stakeholder, a consultant, and a researcher. The first theme is that of the on-the-ground issues and losses that are caused by mass tourism overshadowing traditional local economies. Where are the opportunities to change this imbalance? The second theme is that of local-level decision-making in development projects. In most cases the voice of local stakeholders is weak or even non-existent. What can be done to reverse that reality? The third theme is that of land/nature disruptions caused by climate change, development decisions, or tourism pressures. How can the people-nature connection be better recognized and protected, especially with respect to livelihood? And the last theme is the current conflicts between the demands of the tourist/visitor and the needs of the local populations and local landscape. What needs to be done to benefit both the visitors and the local populations in a more equitable manner? The analysis of these four themes in three different landscapes is presented and several examples of local solutions are discussed. This session seeks to spark further discussion of possible solutions to the questions posed above.

description: Improving the light trapping in a module results in an increase in the generated current. Consequently, an optimization of the front grid metallization of the cell is required for the best trade-off between series resistance, shading, and recombination losses. For this purpose, we combine ray tracing and electrical solar cell and module calculations that explicitly account for cell and module interactions. Our model bases on experimentally verified input parameters: We determine the electrical and optical properties of the front metal fingers of passivated emitter and rear cells (PERC). We show that the effective optical width of the front metal fingers in the module is significantly reduced by 54%. The optimized simulated module has 120 half-size PERC with 20.2% cell efficiency and has an output power of 295.2 W. This is achieved with an increased number of 120 front metal fingers per cell, four white-colored cell interconnection ribbons (CIR), and an increased cell spacing. Applying these optimized design changes to an experimental module we measure a module power output of 294.8 W and a cell-to-module (CTM) factor of 1.02. Measured and simulated power agree and the deviations in Voc, Isc and FF are less than 0.91%rel. We perform a module power gain analysis for the fabricated module and simulate a potential maximum module power of 374.1 W when including further improvements.

description: This paper presents the coupling of a building thermal simulation code with genetic algorithms (GAs). GAs are randomized search algorithms that are based on the mechanisms of natural selection and genetics. We show that this coupling allows the location of defective sub-models of a building thermal model i.e. parts of model that are responsible for the disagreements between measurements and model predictions. The method first of all is checked and validated on the basis of a numerical model of a building taken as reference. It is then applied to a real building case. The results show that the method could constitute an efficient tool when checking the model validity.

description: We characterize the surface passivation properties of ultrathin titanium oxide (TiOx) films deposited by atomic layer deposition (ALD) on crystalline silicon by means of carrier lifetime measurements. We compare different silicon surface treatments prior to TiOx deposition, such as native silicon oxide (SiOy), chemically grown SiOy and thermally grown SiOy. The best passivation quality is achieved with a native SiOy grown over 4 months and a TiOx layer thickness of 5 nm, resulting in an effective lifetime of 1.2 ms on 1.3 Ωcm p-type float-zone silicon. The measured maximum lifetime corresponds to an implied open-circuit voltage (iVoc) of 710 mV. For thinner TiOx layers the passivation quality is reduced, however, samples passivated with only 2 nm of TiOx still show a lifetime of 612 μs and an iVoc of 694 mV. The contact resistivity of the TiOx including the SiOy interlayer between the silicon wafer and the TiOx is below 0.8 Ωcm2. The combination of excellent surface passivation and low contact resistivity has the potential for silicon solar cells with efficiencies exceeding 26%.

description: We evaluate the optical performance of PV modules with respect to an increase in short circuit current density. Our evaluation is based on the combination of ray tracing simulations and measurements on test modules with four types of backsheets: Two of them are structured, the third is white and diffusively reflecting and the fourth reflects no light. Under normal incidence, structured backsheets reflect incoming light at an angle that causes total internal reflection at the glass/air interface, which guides the light to the solar cell surface. Three different irradiance conditions are studied: a) standard testing conditions (STC) with light incident perpendicular to the module surface, b) variation in the angle of incidence and c) light source with mean annual distribution of angles of incidence. Using the measured refractive index data in ray tracing simulations we find a short circuit current density (Jsc) gain of up to 0.9 mA/cm2 (2.3%) for monofacial cells and a structured backsheet, when compared to a white backsheet with diffuse reflection. For bifacial cells we calculate an even larger Jsc increase of 1.4 mA/cm2 (3.6%). The Jsc increase is larger for bifacial cells, since some light is transmitted through the cells and thus more light interacts with the backsheet. Our optical loss analysis reveals the best performance in STC for edge-aligned Ag grooves. This structure reduces absorption losses from 1.8 mA/cm2 to 0.3 mA/cm and reflection losses from 0.7 mA/cm to 0 mA/cm. This trend also holds under various angles of incidence as confirmed consistently by Jsc measurements and ray racing simulations. Simulations using an annual light source emitting a mean annual distribution of angles of incidence reveal grooves in both orientations edge alignment and east-west alignment achieve similar current gains of up to 1.5% for mono- and of 2.5% for bifacial cells compared to modules with white back sheets. This indicates that for modules with light guiding structures such as these backsheets optimization for STC differs from optimization for annul yield.
title: Tourism, Dams and Greed: Lessons from the destruction of a rural cultural landscape in Crete

description: Four thousand years of shaping the landscape, developing sustainable agricultural practices and products, and forming a symbiotic relationship with ecological systems in the Aposelemis Valley of Crete has been disrupted due to the building of a large dam in the heart of that landscape. The politics and decision-making that resulted in the building and implementation of this dam are already documented and analyzed in a recent paper (Chifos, et al, 2019). This paper re-examines what happened in this Valley from the perspective of the cultural/heritage advocates and where the barriers to protecting and maintaining this landscape were and still are. This thriving rural landscape with five inhabited old villages, was recognized as a Natura site, a Ramsar site, was experiencing new archeological finds from Minoan, Roman, and Venetian eras, as well as being championed by local cultural associations, an agricultural cooperative, active farmers and shepherds, and environmentalists. Every such place cannot become a designated cultural landscape through UNESCO, IUCN or other international or national programs. It is not clear that such designations would have stopped the momentum of this water resource management outcome. How can active living traditional rural landscapes survive conflicts with the demands of hyper-tourism, urban growth, EU policies, and centralized governance? This analysis of the Crete case provides an opportunity to identify the weaknesses and world views that left this rural landscape vulnerable to such destruction. Local and regional strategies, as well as the role of local decision-making, that could have prevented or lessened this destruction are discussed, contributing to the ongoing search for how to empower active living rural cultural landscapes to co-exist in a world of rapid change.

description: We introduce a novel methodology for mapping academic institutions based on their journal publication profiles. We believe that journals in which researchers from academic institutions publish their works can be considered as useful identifiers for representing the relationships between these institutions and establishing comparisons. However, when academic journals are used for research output representation, distinctions must be introduced between them, based on their value as institution descriptors. This leads us to the use of journal weights attached to the institution identifiers. Since a journal in which researchers from a large proportion of institutions published their papers may be a bad indicator of similarity between two academic institutions, it seems reasonable to weight it in accordance with how frequently researchers from different institutions published their papers in this journal. Cluster analysis can then be applied to group the academic institutions, and dendrograms can be provided to illustrate groups of institutions following agglomerative hierarchical clustering. In order to test this methodology, we use a sample of Spanish universities as a case study. We first map the study sample according to an institution's overall research output, then we use it for two scientific fields (Information and Communication Technologies, as well as Medicine and Pharmacology) as a means to demonstrate how our methodology can be applied, not only for analyzing institutions as a whole, but also in different disciplinary contexts.
