Η ανάγκη για γρήγορους ρυθμούς προσαρμογής σε συνδυασμό με τις παραγωγικότερες πρακτικές, την ταχύτερη ανταπόκριση στις απαιτήσεις και λιγότερη γραφειοκρατία, οδήγησαν στην ανάπτυξη των ευέλικτων μεθόδων (Agile Methodology) που παρέχουν τις κατάλληλες υποδομές για την ανάπτυξη λογισμικού. Στην παρούσα εργασία, δίνεται έμφαση στα εργαλεία και τις πρακτικές του DevOps που χρησιμοποιούνται για την αυτοματοποίηση διαδικασιών ανάπτυξης και τη συνεχή παράδοση του λογισμικού πληροφοριακού συστήματος, έχοντας ως προτεραιότητα την μέγιστη ικανοποίηση του πελάτη. Παράλληλα, αναλύονται τα κέντρα υγείας ως μία μορφή παροχής ιατρικής περίθαλψης που προσφέρουν βασικές υπηρεσίες φροντίδας για την βελτίωση της υγείας του ασθενή. Στο αρχικό τμήμα της παρούσας εργασίας γίνεται περαιτέρω περιγραφή των παραπάνω εννοιών, ενώ στο δεύτερο τμήμα γίνεται ανάλυση των διαδικασιών που περιγράφουν τη θεραπευτική αγωγή του ασθενή στο κέντρο υγείας, ενώ επίσης γίνεται μία αναφορά στους λόγους εξόδου του από αυτό. Τέλος, παρατίθεται μέσα από εικόνες το πληροφοριακό σύστημα που χρησιμοποιεί ένα τυπικό κέντρο υγείας για τις διαδικασίες της θεραπευτικής αγωγής, παρέχοντας με αυτόν τον τρόπο άμεση φροντίδα στον ασθενή, ασφάλεια των δεδομένων, διαχείριση των ιατρικών πληροφοριών του και γενικά τη βέλτιστη δυνατή παρακολούθηση της υγείας του.

description: Thin film barrier layers based on plasma enhanced chemical vapour deposition (PECVD) are used
in various ways in thin film solar technology for example as insulating layers, diffusion barriers or encapsulation
coatings.
The problem in thin film deposition is always to prevent pinholes to obtain perfect layers. Especially, insulation
layers on metal foils which can be used as substrate material for thin film solar modules must be pinhole free;
otherwise, two pinholes lead to a shortcut between the monolithically serial connected solar cells and cause a total
loss [1]. Purpose of the presented work was to detect, to identify and to investigate the pinholes; and afterwards to
prevent them and if it is necessary to adapt the deposition process.

description: The influence of printing height of the seed layer on the front side metallization was investigated.
Therefore, solar cells were metalized using the aerosol printing technique and the seed layer ink for the
metallization of solar cells (SISC) developed at Fraunhofer ISE. The single lines were deposited one over each
other increasing the amount of ink per contact area. After contact firing and light-induced plating, the contact
resistance was determined using the transfer-length model (TLM). The finger geometry was determined from
cross sectional measurements and the conductivity from 4-probe measurements. In order to analyse the
relationship between the amount of printed ink and the contact quality, the metal contacts were removed in an
HNO3/HF etching step and the metal semiconductor interface was analyzed via SEM images. It could be shown
that a very thin single-printed seed layer leads to the best contact properties.
Deformation Behavior of Tungsten Single Crystals During Wedge Nanoindentation - a Numerical Study
Creators: name: Volz, Tillmann
Publisher: name: Karlsruhe
Year: 2020

description: The present work aims at the numerical investigations on the plastic defor-mation behavior of tungsten single crystals on the microscale, based on finite-element (FE) wedge nanoindentation simulations. These numerical studies on plasticity of body-centered cubic materials in the range of na-nometers to few micrometers require not only an incorporation of a crystal plasticity model to describe slip dominated plastic deformation in the FE-simulations but moreover, the consideration of geometrically necessary dislocations (GND) and non-Schmid effects. Thus, an existing crystal plastici-ty model was extended to determine gradients of plastic shear and non-Schmid effects for the implementation of enhanced FE-simulations of wedge nanoindentation. A comprehensive evaluation of the influence of GNDs and non-Schmid effects on the plastic deformation response of the single crystal was performed under plane strain conditions. Dependent on the applied model, a significant difference in the stress state, the plastic shear on active slip systems and material pile-up around the indenter was observed. In contrast, solely slight deviations in the density of GNDs and crystal lattice rotation under the residual imprint were found. With the gradient-based crystal plasticity model, a size dependency of the plastic deformation could be described in addition. Further, a comparison between numerical and experimental results regarding GNDs, crystal lattice rotation and the residual geometry of the indent was performed. A very good agreement between the experimental and simulated deformed geometry of the specimen was found in the crystal plasticity simulation. The comparison of the GND density and lattice rotation in the region under the indenter flanks showed a good agree-ment as well. However, all numerical simulations overestimate both, the crystal lattice rotation and density of GNDs that occur in the region under the indenter tip.

description: Siliconcarbide (SiC) transistors have a much lower switching energy and lower conduction losses than
conventional silicon based IGBTs or MOSFETs. In previous measurements their suitability for the application in PVinverters
has been proven. The efficiency could be increased by more than 2 % with SiC-transistors compared to
commercially available PV-inverters with silicon transistors [1], [2]. But these semiconductors offer further potential
not only by increasing the efficiency, but also by increasing the switching frequency, which helps to reduce the size
of the inductive components. This paper will show a possibility how to improve the power density together with the
efficiency of a photovoltaic inverter by using silicon carbide transistors.

description: Landauer's formula is the standard theoretical tool to examine ballistic transport in nano- and meso-scale junctions, but it necessitates that any variation of the junction with time must be slow compared to characteristic times of the system, e.g., the relaxation time of local excitations. Transport through structurally dynamic junctions is, however, increasingly of interest for sensing, harnessing fluctuations, and real-time control. Here, we calculate the steady-state current when relaxation of electrons in the reservoirs is present and demonstrate that it gives rise to three regimes of behavior: weak relaxation gives a contact-limited current; strong relaxation localizes electrons, distorting their natural dynamics and reducing the current; and in an intermediate regime the Landauer view of the system only is recovered. We also demonstrate that a simple equation of motion emerges, which is suitable for efficiently simulating time-dependent transport.

description: The influence of plasmon resonances in disc-shaped Ag nanoparticles on the spectral dependence of
photocurrents has been studied in Si test solar cells. By use of electron beam lithography, well-defined disc-shaped
Ag nanoparticles with a height of 25 nm and with two different height to diameter ratios are produced on SiNx films
on top of thin film Si test solar cells. The effect on the external quantum efficiency is investigated by a combination
of optical reflection/scattering measurements and wavelength dependent photocurrent and quantum efficiency
measurements on the test solar cells. The experimental results are compared to calculations of particle plasmon
resonance wavelengths for Ag nanodiscs on SiNx.

description: We demonstrate the growth of thin films of molybdenum ditelluride and molybdenum diselenide on sapphire substrates by molecular beam epitaxy. In-situ structural and chemical analyses reveal stoichiometric layered film growth with atomically smooth surface morphologies. Film growth along the (001) direction is confirmed by X-ray diffraction, and the crystalline nature of growth in the 2H phase is evident from Raman spectroscopy. Transmission electron microscopy is used to confirm the layered film structure and hexagonal arrangement of surface atoms. Temperature dependent electrical measurements show an insulating behavior which agrees well with a two-dimensional variable-range hopping model, suggesting that transport in these films is dominated by localized charge-carrier states.

description: In this paper we investigate the mass assembly history of ultramassive (Mstar > 10^11Msun) dense (Sigma = Mstar/(2*pi*Re^2) > 2500 Msun/pc^2) early-type galaxies (ETGs) over the last 9 Gyr. We have traced the evolution of the number density rho of ultramassive dense ETGs and have compared their structural (effective radius Re and stellar mass Mstar) and dynamical (velocity dispersion sigma_e) parameters over the redshift range 0 < z < 1.6. We have derived the number density at 1.6 < z < 1 from the MUNICS and GOODS-South surveys, while we have used the COSMOS and SDSS spectroscopic surveys to probe the intermediate and local redshift range. For the comparison of the dynamical and structural parameters, we have collected the ultramassive dense ETGs at 1.2 < z < 1.6 for which velocity dispersion measurements are available (11 ETGs). For 4 of them we present unpublished estimates of sigma_e. We probe the intermediate redshift range, and the local universe using the samples of ETGs by Saglia et al. (2010), Zahid et al. (2015), and by Thomas et al. (2010). We find that the number density of ultramassive dense ETGs evolves as rho(z) = K*(1 + z)^(0.3\pm0.8) implying a decrease of ~ 25% of the population since z = 1.6. By comparing the values of Re, Mstar, and sigma_e of ultramassive dense ETGs over the range 0 < z < 1.6 we find that all the high-z ETGs have a counterpart in the local universe. This implies either that the majority (~70%) of ultramassive dense ETGs has already completed its assembly and its shaping at = 1.4, or that, if a significant fraction of them evolves in size, new ultramassive dense ETGs must form at z < 1.5 to maintain their number density almost constant. The difficulty into identify good progenitors for these new dense ETGs at z < 1.5, and the stellar populations properties of local ultramassive dense ETGs point toward the first hypothesis.

description: Inhomogeneous illumination, e.g. due to partial shading of one photovoltaic module in a photovoltaic string,
limits the common current of all modules of the string. Depending on the string configuration, partial shading reduces the
output voltage of the string dramatically by bypassing the affected module. The voltage drop in one string of a parallel
connection forces the inverter to decide whether to operate all strings at the reduced voltage or to force the affected string to
the optimal voltage of the remaining strings. Both operating points lead to high mismatch losses that additionally decrease the
output power of the photovoltaic system. The Dynamic String Interconnection (DSI) provides independent maximum power
point tracking of multiple photovoltaic strings. We present a prototype of the dynamic string interconnection with an
electrical conversion efficiency up to DSI = 97.8 %. Simulations of the circuit and a test system at the rooftop of the ipe
prove the individual maximum power point tracking of the strings and demonstrate a gain in efficiency of about 1.2 %
compared to the parallel connection of the strings. This initial efficiency gain results from the compensation of the string
tolerances. If one of the modules of the test system is bypassed, the gain in system efficiency rises to 9.5 %.

description: In this paper first results on the stability and applicability for an inline sputtering pilot system (Applied
Materials ATON 500 Ev + Sp) with industrially feasible deposition rates are shown. The system consists of two
different process chambers, one for thermal evaporation and a second one for sputter deposition of two different
metals.
The applicability of the sputtering process for the front side metallization has first been determined in an
experimental setup on a non PV dedicated system. Different experiments were performed to evaluate the properties
of the sputtered layers. To determine the possible damage of the passivation layer during the sputter deposition, test
structures for minority carrier lifetime measurements were prepared. The layer growth of the sputtered metal depends
on the temperature of the substrate and the sputtered target material properties as well. To determine the layer growth
and the homogeneity, experiments were performed to evaluate the sheet resistance and to identify their relation to an
industrial inline metallization process with various deposition rates after transferring the process to the pilot system.
Sheet resistance measurements are additionally used to analyze a very important aspect of the metallization process,
the silicide formation. Depending on the applied metal for the deposited layer, the time and temperature of the
tempering process has to be chosen individually in order to from a suitable silicide layer for subsequent contact
formation.

multielement analytical techniques can quantitatively monitor impurity concentrations in a wide variety of PV grade
materials currently considered for large scale productions, such as solar grade (SoG) Silicon, CdTe, CdS or for
those which are potentially considered to be used in the near future, like CIGS. Since the GDMS techniques are
survey methods, they are especially the most cost effective in monitoring process with 4N to 6N or 99.99 –
99.9999% pure materials when still many impurity elements are of interest.
Protocol for a multicenter study on (cost)effectiveness of the Back At work After Surgery (BAAS): a clinical pathway for knee arthroplasty.

description: Background: Optimizing return to work (RTW) after knee arthroplasty (KA) is becoming increasingly important due to a growing incidence of KA and poor RTW outcomes after KA. We developed the Back At work After Surgery (BAAS) clinical pathway for optimized RTW after KA. Since the effectiveness and cost analysis of the BAAS clinical pathway are still unknown, analysis on effectiveness and costs of BAAS is imperative. Method: This protocol paper has been written in line with the standards of Standard Protocol Items: Recommendations for Interventional Trails. To assess the effectiveness and cost-effectiveness for RTW, we will perform a multicenter prospective cohort study with patients who decided to receive a total KA (TKA) or an unicompartmental KA (UKA). To evaluate the effectiveness of BAAS regarding RTW, a comparison to usual care will be made using individual patient data on RTW from prospectively performed cohort studies in the Netherlands. Discussion: One of the strengths of this study is that the feasibility for the BAAS clinical pathway was tested at first hand. Also, we will use validated questionnaires and functional tests to assess the patient’s recovery using robust outcomes. Moreover, the intervention was performed in two hospitals serving the targeted patient group and to reduce selection bias and improve generalizability. The limitations of this study protocol are that the lead author has an active role as a medical case manager (MCM) in one of the hospitals. Additionally, we will use the data from other prospective Dutch cohort studies to compare our findings regarding RTW to usual care. Since we will not perform an RCT, we will use propensity analysis to reduce the bias due to possible differences between these cohorts.

description: Verification of temporal logic properties plays a crucial role in proving the desired behaviors of continuous systems. In this paper, we propose an interval method that verifies the properties described by a bounded signal temporal logic. We relax the problem so that if the verification process cannot succeed at the prescribed precision, it outputs an inconclusive result. The problem is solved by an efficient and rigorous monitoring algorithm. This algorithm performs a forward simulation of a continuous-time dynamical system, detects a set of time intervals in which the atomic propositions hold, and validates the property by propagating the time intervals. In each step, the continuous state at a certain time is enclosed by an interval vector that is proven to contain a unique solution. We experimentally demonstrate the utility of the proposed method in formal analysis of nonlinear and complex continuous systems.

Συχνά χρησιμοποιείται για την ανάλυση αλληλεπιδράσεων μεταξύ ανταγωνιστών στην οικονομία, την πολιτική και άλλους τομείς. Η διαπραγμάτευση, από την άλλη πλευρά, είναι μια διαδικασία κατά την οποία δύο ή περισσότερα μέρη συμμετέχουν σε συζήτηση και συμβιβασμό για την επίτευξη συμφωνίας ή λύσης. Συνολικά, η θεωρία παιγνίων παρέχει ένα χρήσιμο πλαίσιο για την κατανόηση των στρατηγικών επιλογών και κινήτρων που αποτελούν τη βάση των διαπραγματεύσεων. Χρησιμοποιώντας τη θεωρία παιγνίων για την ανάλυση σεναρίων διαπραγμάτευσης, οι διαπραγματευτές μπορούν να προβλέψουν καλύτερα τις ενέργειες άλλων μερών και να λάβουν πιο ενημερωμένες αποφάσεις. Σκοπός της συγκεκριμένης πρότασης είναι η προσέγγιση της διαπραγμάτευσης στο χώρο του φαρμάκου, στην Ελληνική πραγματικότητα, με τη Θεωρία Παιγνίων. Να εξετασθεί εάν μπορεί να προσφέρει ένα πλαίσιο στρατηγικής σκέψης, το οποίο να επιτρέπει να μελετηθεί ποσοτικά. Επιπλέον, να διαπιστωθεί εάν με την ορθολογική προσέγγιση της Θεωρίας Παιγνίων μπορούν να απεικονιστούν και να διερευνηθούν οι διαθέσιμες στρατηγικές και να προσδιοριστούν οι βέλτιστες επιλογές των αντίπαλων μερών.

description: A series of μc-Si:H thin films with high deposition rate were prepared by very high frequency plasma
enhanced chemical vapor deposition (VHF-PECVD) process under high power and high-pressure conditions.
Keeping the other parameters constant, the total gas flow rate was adjusted from 100sccm to 500sccm, which led to
gradually decreased gas residence time. The influence of total gas flow rate on the deposition process, electrical and
micro-structural properties was studied in detail. Plasma emission was recorded by optical emission spectroscopy
during μc-Si:H absorber layer deposition at total gas flow rate between 100sccm and 500sccm. The results showed
that the photosensitivity (p/d) of μc-Si:H film was maximum and the microstructure factor (R) was minimum when
the ratio of H*/H* had a local minimum value at 300sccm. The above results were analyzed using the concept of
the gas residence time. It found that device grade microcrystalline silicon materials should be prepared at proper gas
residence time.Those μc-Si:H films deposited at different total gas flow rate were applied as the absorber layers in
single-junction μc-Si:H solar cells. Conversion efficiency of 8.11% has been obtained at 8.5Å/s with 300sccm total
gas flow rate.

description: We revisit hydrogen shell burning on white dwarfs (WDs) with higher mass accretion rates than the stability limit, \dot M_stable, above which hydrogen burning is stable. Novae occur with mass accretion rates below the limit. For an accretion rate > \dot M_stable, a first hydrogen shell flash occurs followed by steady nuclear burning, so the shell burning will not be quenched as long as the WD continuously accretes matter. On the basis of this picture, some persistent supersoft X-ray sources can be explained by binary models with high accretion rates. In some recent studies, however, the claim has been made that no steady hydrogen shell burning exists even for accretion rates > \dot M_{\rm stable}. We demonstrate that, in such cases, repetitive flashes occurred because mass accretion was artificially controlled. If we stop mass accretion during the outburst, no new nuclear fuel is supplied, so the shell burning will eventually stop. If we resume mass accretion after some time, the next outburst eventually occurs. In this way, we can design the duration of outburst and interpulse time with manipulated mass accretion. We call such a controlled nova a "forced nova." These forced novae, if they exist, could have much shorter recurrence periods than "natural novae." We have obtained the shortest recurrence periods for forced novae for various WD masses. Based on the results, we revisit WD masses of some recurrent novae including T Pyx.

description: 24th European Photovoltaic Solar Energy Conference, 21-25 September 2009, Hamburg, Germany; 1465-1468
description: This paper describes the development of a technique to overcome the adhesion problems associated
with the use of electroless pating in many high efficiency solar cell structures. Poor metal to silicon adhesion can
cause the deposited metal contact to peel and lift away from the grooves of the cell, limiting fill factor due to high
series resistance. Through our development of a process which enables a better chemical bonding between the silicon
and the electrolessly deposited metal we have been able to eliminate the overplating and adhesion problems
previously observed. This is demonstrated by analysing plating on inkjet printed and laser doped cell structures.

description: We prove in the context of local $Tb$ theorems with $L^p$ type testing conditions an improved version of Cotlar's inequality. This is related to the problem of removing the so called buffer assumption of Hytönen-Nazarov, which is the final barrier for the full solution of S. Hofmann's problem. We also investigate the problem of extending the Hytönen-Nazarov result to non-homogeneous measures. We work not just with the Lebesgue measure but with measures $μ$ in $\mathbb{R}^d$ satisfying $μ(B(x,r)) \le Cr^n$, $n \in (0, d]$. The range of exponents in the Cotlar type inequality depend on $n$. Without assuming buffer we get the full range of exponents $p,q \in (1,2]$ for measures with $n \le 1$, and in general we get $p, q \in [2-ε(n), 2]$, $ε(n) > 0$. Consequences for (non-homogeneous) local $Tb$ theorems are discussed.

description: The increasing usage of non-linear electrical loads in the low voltage grid, leads to new challenges
to the electrical network. These loads, such as electronic rectifiers or converters will strain the grid by
introducing current harmonics. They create a voltage drop over the grid impedance, with respective spectra, that
leads to a non-sinusoidal grid voltage. PV inverters that feed the grid decentrally and can support the grid with
reactive power are generally capable of not only supplying the grid with a sinusoidal active current, but also
specific non-sinusoidal reactive currents depending on the quick response of the current control. A compensating
current can be determined with the measured grid voltage and respectively the complex and frequency dependent
grid impedance, which ideally eliminates the voltage harmonics. For that, the grid voltage signal needs to be
analysed by a group of digital filters tuned to different harmonics. Thus, from the filter results and the knowledge
of the grid impedance angle or adequate control algorithms, the compensating current can be determined and
adjusted.

description: Recently new Distributed Maximum Power Point Tracking (DMPPT) architectures have been
released and launched to the market as an alternative to traditional MPPT configurations. These innovative
solutions, based on a DC-DC converter for every single PV panel, have been specially designed to optimize the
performance of heterogeneous PV systems, such as those integrated in buildings. Ideally, they can solve any
mismatching problem, but actually this is not always feasible. This paper analyzes the performance of this kind
of architectures in order to demonstrate that they fail under certain working conditions, depending on the
operating range of employed DC-DC converters and the voltage at the input of the PV inverter.

description: Efficiency is a key point in the design of the PhotoVoltaic (PV) plant, especially for the inverter
connected to the grid. The efficiency of such inverters is defined by its components and the way they are used,
meaning the topology. Multi-level topologies might reduce the switching losses by decreasing the switched
voltage and the filter needed. These topologies become more and more used in low voltage application such as
the inverters connected to the grid. The wide number of different topologies makes the comparison difficult, so
this work deals with a generic method to evaluate the efficiency of a multi-level converter. The most known
topologies have been compared with Silicon IGBT and diodes and the best number of levels has been defined for
each one. Anyway, all the topologies are not equal and the “Stacked Cell” seems to be the best for an efficiency
point of view.

description: MWT (Metal Wrap Through) solar cells have powerful structural merits compared to conventional
screen-printed solar cells. In particular, MWT cells can reduce shading loss by removing bus electrodes on the front
side. In addition, MWT cells can minimize the power loss due to the electrode series resistance, which can be
reduced by increasing the numbers of bus electrodes on the rear side. In this paper, we developed and tested
multicrystalline (mc) Si MWT solar cell with 4 busbar on the rear side. Here, the structure of the MWT cell is
proposed to minimize the power loss by shading and resistance of cells. The calculated results showed that the power
loss in MWT solar cells can be halved compared to the conventional solar cells by adjusting the cell structure and the
electrode shape. Moreover, advanced fine line printing technology was applied to form the front electrodes with high
aspect ratio. As a result, it is demonstrated that Jsc increased from 34.6mA/cm2 to 36.3mA/cm2 and solar cell
efficiency 16.7% at 156 × 156 mm2 size was obtained by the effect of MWT structure & fine electrodes.

description: A vital part in thin film solar cells is the transparent conductive layer. Highly conductive TCOs are the
material type most widely used. However, these materials have some drawback, such as brittleness and a maximum
transmittance for a certain sheet resistance. Alternative materials, such as metal foils, nanowires and organic
conductors are discussed and ranked for their suitability in solar cells. At this moment, organic conductors have a
performance inferior to inorganic conductors. Recent results of both modeling and experiments obtained at TNO
demonstrate that the combination of TCOs and metal grids are the most viable option for improvement of TCO
performance beyond the limits of a single material. For this demonstration commercial ITO on PET was used, on
which metal grid was applied by easily upscalable wet chemical deposition techniques. The sheet resistivity was
increased by a factor of over 400, with less than 5% loss additional in transmittance. A sheet resistance of 0.1 W/sq
was obtained with a transparency above 83%.
