description: The development of highly automated driving requires dynamic approaches that anticipate the cognitive state of the driver. In this paper, a cognitive model is developed that simulates a spectrum of cognitive processing and the development of situation awareness and attention guidance in different takeover situations. In order to adapt cognitive assistance systems according to individuals in different situations, it is necessary to understand and simulate dynamic processes that are performed during a takeover. To validly represent cognitive processing in a dynamic environment, the model covers different strategies of cognitive and visual processes during the takeover. To simulate the visual processing in detail, a new module for the visual attention within different traffic environments is used. The model starts with a non-driving-related task, attends the takeover request, makes an action decision and executes the corresponding action. It is evaluated against empirical data in six different driving scenarios, including three maneuvers. The interaction with different dynamic traffic scenarios that vary in their complexity is additionally represented within the model. Predictions show variances in reaction times. Furthermore, a spectrum of driving behavior in certain situations is represented and how situation awareness is gained during the takeover process. Based on such a cognitive model, an automated system could classify the driver’s takeover readiness, derive the expected takeover quality and adapt the cognitive assistance for takeovers accordingly to increase safety.

description: This paper uses a spatial Aloha model to describe a distributed autonomous wireless network in which a group of transmit-receive pairs (users) shares a common collision channel via slotted-Aloha-like random access. The objective of this study is to develop an intelligent algorithm to be embedded into the transceivers so that all users know how to self-tune their medium access probability (MAP) to achieve overall Pareto optimality in terms of network throughput under spatial reuse while maintaining network stability. While the optimal solution requires each user to have complete information about the network, our proposed algorithm only requires users to have local information. The fundamental of our algorithm is that the users will first self-organize into a number of non-overlapping neighborhoods, and the user with the maximum node degree in each neighborhood is elected as the local leader (LL). Each LL then adjusts its MAP according to a parameter R which indicates the radio intensity level in its neighboring region, whereas the remaining users in the neighborhood simply follow the same MAP value. We show that by ensuring R less than or equal to 2 at the LLs, the stability of the entire network can be assured even when each user only has partial network information. For practical implementation, we propose each LL to use R=2 as the constant reference signal to its built-in proportional and integral controller. The settings of the control parameters are discussed and we validate through simulations that the proposed method is able to achieve close-to-Pareto-front throughput.

description: Nucleation and growth is the dominant relaxation mechanism driving first order phase transitions. In two-dimensional at systems nucleation has been applied to a wide range of problems in physics, chemistry and biology. Here we study nucleation and growth of two-dimensional phases lying on curved surfaces and show that curvature modify both, critical sizes of nuclei and paths towards the equilibrium phase. In curved space nucleation and growth becomes inherently inhomogeneous and critical nuclei form faster on regions of positive Gaussian curvature. Substrates of varying shape display complex energy landscapes with several geometry-induced local minima, where initially propagating nuclei become stabilized and trapped by the underlying curvature.

description: The main reason why users and vendors convey their business online is that it gives unique advantages over purchases online and also to their store-bound opponents online. The most advantages are the flexibility, speed, and low cost of the high levels of data. Since early 2016, data has been considered the main source of information integrity. Most e-commerce websites use everyday time frames to collect tons of data aboutuser interaction to learn how they surf the web, what kind of things they purchase, and what sort of sites they visit to get their product. The forms of data give different analytical processing speeds to preserve and visualise the data. Most methods of data visualisation are very complex to understand thereby making less for people who might want to make use of the data online. This paper looks into a pseudo algorithm for processing and understanding natural structures in user interaction data to e-commerce websites, these data contain fixation locations and durations and also the stress level of the users while they look for a certain product online. The data is analysed based on this cognitive level to determine the level of stress or relaxation mood of the user to arrive at a particular choice of product. The result shows that for a less complex website, the relaxed mood is the most significant expression of the users and most likely the ergonomics attributes to building an e-commerce website.

description: We apply the low-energy theorems to analyze the recent lattice QCD results for the two-nucleon system at a pion mass of $M_π\simeq 450$ MeV obtained by the NPLQCD collaboration. We find that the binding energies of the deuteron and dineutron are inconsistent with the low-energy behavior of the corresponding phase shifts within the quoted uncertainties and vice versa. Using the binding energies of the deuteron and dineutron as input, we employ the low-energy theorems to predict the phase shifts and extract the scattering length and the effective range in the $^3S_1$ and $^1S_0$ channels. Our results for these quantities are consistent with those obtained by the NPLQCD collaboration from effective field theory analyses but are in conflict with their determination based on the effective-range approximation.

description: In order to reduce the power-generating cost of crystalline silicon-based solar cells, it is necessary
to achieve a high conversion efficiency with thinner crystalline silicon wafers. The Voc of a very thin HIT solar
cell reached 747 mV by improving the passivation capability of the a-Si/c-Si interface. The Hall mobility of a
transparent conductive oxide increased 1.3 times. With these technical improvements, the conversion efficiency
of the HIT solar cell rose to 23.0%. In order to suppress the production cost, we also applied these improvements to
thin HIT solar cells. We successfully obtained a conversion efficiency of 22.8% for a 98-μm-thick HIT solar cell.
Because of its excellent conversion efficiency, the HIT solar cell has received much attention, and many
researchers have been studying amorphous–silicon/crystalline-silicon heterojunction solar cells.

description: A kinetic theory is developed for exonuclease-deficient DNA polymerases, based on the experimental observation that the rates depend not only on the newly incorporated nucleotide, but also on the previous one, leading to the growth of Markovian DNA sequences from a Bernoullian template. The dependences on nucleotide concentrations and template sequence are explicitly taken into account. In this framework, the kinetic and thermodynamic properties of DNA replication, in particular, the mean growth velocity, the error probability, and the entropy production in terms of the rate constants and the concentrations are calculated analytically. Theory is compared with numerical simulations for the DNA polymerases of T7 viruses and human mitochondria.

description: I-V characteristics of bifacial and mono-facial modules in the test roof-top PV field in Jerusalem were
monitored simultaneously. Analysis of factors affecting the energy gains due to contribution of bifacial module back
is based on time-of-day, daily and monthly energy generation data. Among these factors: diffuse to global radiation
ratio, season and time-of-day Sun position. Daily energy gain of an in-field bifacial vs. a mono-facial module at
underlying surface albedo ~0.50 varies in the range 5 – 38 %. An evaluated equivalent efficiency of 21 % is based on
the measured yearly gain for bifacial solar cells with a front efficiency 18 %. Optimization of the PV field design
should increase these values.

description: Continuously decreasing system prices and levelized cost of electricity (LCOE) have triggered
enormous market growth in photovoltaics. As c-Si technology will be the dominating technology for the foreseeable
future, hyperpure polysilicon – the key raw material for high-quality and high-efficiency PV systems – will also see
fast-growing demand. The polysilicon production capacities are expected to grow significantly and exceed 500,000
metric tons by 2014, supporting annual PV installations of up to 80 GW. As silicon is one of the most abundant
elements on the planet, capital and engineering skills are the only resources needed to meet the world’s electricity
demand. But to accommodate the demand for PV systems with even lower LCOEs, only those suppliers with the
lowest cost and undisputed product quality will be able to survive in the future.

Environmental Impacts, Recycling and Waste Management

description: The paper is addressed primarily for non-metallurgists interested in gaining an inside view into the
factors affecting the effectiveness of the recycling process. Whilst the metallurgical content covers most of the
relevant basics, it is delivered in a simple and direct form. A brief overview of the metallurgical project structure is
provided within the specific context of photovoltaics recycling aiming primarily for metals recovery. Essentials of
technical and economical feasibility of sustainable recycled-pay-metal production are presented. Emphasis is placed
on novel process flowsheet development from low-grade, low-to-medium throughput, highly variable feedstock – all
these being characteristics of the “recycling feed”, defined as such. Moreover, a quick review of the criteria for
selection of commercially proven unit operations enabling the said novel flowsheet is provided. A summary of key
factors influencing the performance of recycling plants from design through ramp-up and full commissioning is
provided. Technical process risk mitigation strategies are reviewed and exemplified, with focus on the recycling of
metals from thin-film photovoltaics. Critical “big picture” success (or failure) factors discussed include process
chemistry cost implications, effect of separation and handling on plant operability, water usage and facility
requirements.

description: We develop a method to extract the characteristic energy of the Urbach energy band tails in thin film
CIGS. By modeling the temperature-dependent internal quantum efficiency (IQET) of CIGS solar cells including
sub–gap absorption, we identify a linear region in a semilogarithmic IQET vs. photon energy plot, which yields the
Urbach energy EU. Measurements of high efficiency (18 %) CIGS solar cells prepared at the Institut für Physikalische
Elektronik (Stuttgart, Germany), yield room temperature Urbach energies around 30 meV in cells with a Ga/(In+Ga)
ratio of 0.35. Cryostat temperature-dependent IQET measurements yield an increasing value of EU from 31 meV at
146 K up to 40 meV at 293 K. Additionally, a conversion from IQET to electroluminescence reveals defect bands
obtained by other groups with spectroscopic measurements.

description: Nowadays the solid state solar cells (SSSC) represent promising low-cost and efficient alternatives to the
silicon based photovoltaic cells. The fundamental research in the SSSC field is mainly based on the thoroughgoing
studies regarding the correlation between the properties (tailored by deposition parameters) of cell components (thin
films) and the solar cell output (photovoltaic response). The paper presents the development of new 3D solid state solar
cells, based on anatase and ZnO hetero-junction with CuxS (x = 1.8-1,96), with and without In2S3 buffer layer. The buffer
layer does not improve the cells electrical properties, due to the CuInS2 formation to the CuxS/In2S3 interface. The use of
ZnO as n-type semiconductor layer is limited by the particular, worm like morphology, which is not match with the CuxS
layer morphology. Good results are reported for cells based on TiO2 anatase as n-type semiconductor, with densenanoporous
morphology.

description: We present results of a blind 21cm HI-line imaging survey of a galaxy overdensity located behind the Milky Way at $\ell,b$ $\approx$ 160 deg, 0.5 deg. The overdensity corresponds to a Zone-of-Avoidance crossing of the Perseus-Pisces Supercluster filament. Although it is known that this filament contains an X-ray galaxy cluster (3C129) hosting two strong radio galaxies, little is known about galaxies associated with this potentially rich cluster because of the high Galactic dust extinction. We mapped a sky area of $\sim$9.6 sq.deg using the Westerbork Synthesis Radio Telescope in a hexagonal mosaic of 35 pointings observed for 12 hours each, in the radial velocity range $cz = 2400 - 16600$ km/s. The survey has a sensitivity of 0.36 mJy/beam rms at a velocity resolution of 16.5 km/s. We detected 211 galaxies, 62% of which have a near-infrared counterpart in the UKIDSS Galactic Plane Survey. We present a catalogue of the HI properties and an HI atlas containing total intensity maps, position-velocity diagrams, global HI profiles and UKIDSS counterpart images. For the resolved galaxies we also present HI velocity fields and radial HI surface density profiles. A brief analysis of the structures outlined by these galaxies finds that 87 of them lie at the distance of the Perseus-Pisces Supercluster ($cz \sim 4000 - 8000$ km/s) and seem to form part of the 3C129 cluster. Further 72 detections trace an overdensity at a velocity of $cz \approx$ 10000 km/s and seem to coincide with a structure predicted from mass density reconstructions in the first 2MASS Redshift Survey.

description: Selective emitter formation for silicon solar cells is very important to achieve high conversion
efficiency . We succeed to fabricate a solar cell with the selective emitter only by laser doping (LD) technique. LD
technique is now noticed as alternative instead of the conventional thermal diffusion method to form junctions in
silicon solar cells. This technique can be operated easily at room temperature and in the atmosphere. Furthermore, the
doping area is formed at only laser irradiated area. This is possible a simple process without additional steps such as
photolithography. In this study, we tried to apply the LD method to the silicon solar cell fabrication process with only
LD. Doping was achieved by utilized two lasers. The first irradiation to form the pn junction was operated with
355nm wavelength laser, the second irradiation to form the selective emitter was operated with 532 nm wavelength
laser. Our results demonstrated the conversion efficiency improved with selective emitter cells, especially F.F.

description: In most cases, graphs are a natural way of representing every kind of data, often nature is referred to as the inherent characteristics and quality of physical phenomena; the natural way for its representation is through a graph. The relationship between human interactions, animals and soil can be represented and depicted as a graph. Also, the most paradigmatic case is that knowledge is presented as a graph and as a form of ontology in relationships and hierarchies among the concepts and words. However, while a long list and sets of data may represent events that can be classified by order or category, graphs that include relationship characteristics allow for a schematic presentation that includes different types of relationship categories. This is the natural assembly, of different types of human behaviour patterns. In this paper, we present human eye movement behaviour patterns in search mode while they are involved in a certain activity like surfing the web. The residual from the data collected is represented in a natural structure in the form of a stalactite plot of residuals from Convolutional Neural Network (CNN) and Recurrent Neural Network (RNN) classification. The residual fit shows that CNN has the highest rate in terms of True positive cases of eye movement behaviour compared to RNN.

description: We report the superconductivity of the CaSn3 single crystal with a AuCu3-type structure, namely cubic space group Pm3m. The superconducting transition temperature TC=4.2 K is determined by the magnetic susceptibility, electrical resistivity, and heat capacity measurements. The magnetization versus magnetic field (M-H) curve at low temperatures shows the typical-II superconducting behavior. The estimated lower and upper critical fields are about 125 Oe and 1.79 T, respectively. The penetration depth λ(0) and coherence length ξ(0) are calculated to be approximately 1147 nm and 136 nm by the Ginzburg-Landau equations. The estimated Sommerfeld coefficient of the normal state γ_N is about 2.9 mJ/mol K2. ΔC/γNTC =1.13 and λep=0.65 suggest that CaSn3 single crystal is a weakly coupled superconductor. Electronic band structure calculations show a complex multi-sheet Fermi surface formed by three bands and a low density of states (DOS) at the Fermi level, which is consistent with the experimental results. Based on the analysis of electron phonon coupling of AX3 compounds (A=Ca, La, and Y; X=Sn and Pb), we theoretically proposed a way to increase TC in the system.

description: Kinetic theory and thermodynamics are applied to DNA polymerases with exonuclease activity, taking into account the dependence of the rates on the previously incorportated nucleotide. The replication fidelity is shown to increase significantly thanks to this dependence at the basis of the mechanism of exonuclease proofreading. In particular, this dependence can provide up to a hundred-fold lowering of the error probability under physiological conditions. Theory is compared with numerical simulations for the DNA polymerases of T7 viruses and human mitochondria.

The paper investigates a semi-hybrid model for eye color detection, it designs an application integrated with a classifier such as a Convolutional Neural Network to improve the speed in detection and eye variance filter. Its accuracy classifies normal features from abnormal features and colors and demonstrates the robustness of the method on three different epochs on facial images.

whereas the samples prepared around 70ºC showed the formation of ZnS films at the beginning of synthesis reaction.
Optical characterization of the films was carried out and the band gap was determined from the corresponding
transmittance and reflectance measurements. The band gap of the films varied in dependence on the deposition
conditions, as a consequence of the resulting composition and morphology.

description: The use of a newly developed time transient 3D CFD model for simulation of uni-directional crystal
growth of Si is demonstrated. The implementation uses an enthalpy formulation and works on fixed grids. At first the
results of a 2D tin solidification benchmark case are shown, which allows a comparison of the new model to two
other codes and to measurements. Next, the model has been applied to an existing industrial mc-Si ingot casting
furnace. Here, the model results include time-transient, 3D temperature profiles, position and shape of the
crystallization front and flow patterns in the liquid Si melt. On cooling, after a certain delay time, the calculated
solidification rate in the center of the ingot is 12 mm/hr, which is practically constant during the complete
crystallization process. The calculated growth rate in the center of the ingot is in good agreement with measurement
data. Besides the results indicate that convective flows in the Si melt influence the net heat transfer to the bottom of
the melt up to the start of the crystallization. From that moment on the latent heat release dominates the solidification
process.

description: In order to achieve solar grade performance, the chalcopyrite CuInSe2 (CISe) growth process by
elemental co-evaporation technique requires a recrystallization. The purpose of the present contribution is the
accurate investigation of the films crystalline properties evolution through the Cu-Poor to Cu-Rich transition in order
to understand the growth mechanisms of CISe. During a CUPRO sequence, the material experiences different
crystalline states owing to the variations of metal ratio y = [Cu]/[In]. The correlation between the grain size and
copper content has been found when thin films are very close to the stoichiometry (y = 1). Moreover, the evolution of
the preferential orientation has been agreed with grain size. Finally, Micro-Raman spectroscopy allows the
identification of different phases present throughout the process.

description: The two-body bound and scattering properties in an one-dimensional harmonic waveguide close to free space magnetic Feshbach resonances are investigated based on the local frame transformation approach within a single partial wave approximation. An energy and magnetic field dependent free space phase shift is adopted in the current theoretical framework. For both $s$- and $p$-wave interaction, the least bound state in the waveguide dissociates into the continuum at the resonant magnetic field where the effective one-dimensional scattering length $a_{\rm 1D}$ diverges. Consequently, the association of atoms into molecules in the waveguide occurs when the magnetic field is swept adiabatically across the pole of $a_{\rm 1D}$. In the vicinity of broad $s$-wave resonances, the resonant magnetic field is nearly independent on the transverse confining frequency $ω_{\perp}$ of the waveguide. Close to $p$-wave and narrow $s$-wave resonances, the resonant magnetic field changes as $ω_{\perp}$ varies.

description: Traditional spectral response experiments in solar cells, such as quantum yields show the dependence
of the excess carrier contribution and respective recombination on the depth of the device in terms of the optical generation.
However, this depth information is masked by the contribution of current continuity that is met by the contributions
of minority as well as majority carriers across the entire depth of the device and commonly the information
on local properties is not reflected straightforwardly. In our approach we have adjusted either constant VOC (c-VOC)
or ISC (c-ISC) by recording the spectral photon fluxes necessary for these conditions. In particular in VOC operation
excess carriers recombine exclusively within the device and thus the signal is more sensitive against recombination.
Our results of the c-VOC and c-ISC experiments for CIGSe-heterodiodes show significant differences in the short wavelength-
regimes. Numerical modelling shows that this difference becomes larger with increasing interface recombination.

description: An eye color detection system can provide a large amount of valuable information about a person, a classification of colors is very useful in documenting events such as pathological changes or defining howa person will respond to ocular medical defects. These classification systems range from basic light or dark descriptions of eye color to grading and employing photographic standards of the static profile froma real-time video capture. This paper adopted the use of a Support Vector Machine (SVM) a procedure that uses a non-separable dataset from the eye authentication matrix, based on the model’s complexity that doesn’t allow for a separating hyperplane axis. The SVM uses a soft margin, a hyperplane that separates many, but not all data points from the input matrix and makes classification based on five different eye color. The model was tested on the dataset on different epochs and the best fit is discussed in the result section.

description: In face recognition system implementation, human factors play a considerable role in the design and interpretation of remote sensing of images for pattern classification. Image sensing and cognition are the critical topics in image interpretation that brings together current state of art procedures which are widely recognised and tackled, especially in facial recognition image sensing with complex input data. It addresses most themes around expertise including the methods for knowledge acquisition and modelling of the expertise behind the modules and systems. This paper uses a facial recognition system at its production stage to test the model’s reliability and accuracy based on users’ subjective perception and real-time cognitive perception of the subjects used for the test procedure. Eighty people were interviewed while we took their skinconductance response (SCR) and they interacted in real-time with the window output of the facial recognition system, this is to obtain a subjective view of their cognitive response to the interface based on the best match of a particular face to its foreground image. The result shows that most participants considered the image fit to be above average match to the original greyscale image and should not be part of feature classification for a facial recognition system.

description: Recently, a fixed-abrasive wire (diamond wire) where diamond grits are fixed on the surface of a
piano wire is attracting much interest because of its advantages such as a higher slicing speed of silicon (Si) ingots
and a water soluble coolant (grinding fluid) without slurry. The diamond wire sawing, however, can have a problem
in the production of crystalline Si (c-Si) solar cells since the surface morphology of as-sliced wafers is different from
that of wafers sliced by a loose-abrasive wire. Therefore, a new cleaning and texturing technique is required. We
developed the texturing process suited for the wafers sliced by a resin-bonded diamond wire and obtained a high
efficiency over 17 % using the single c-Si wafers sliced by this method. It has thus been confirmed that the wafers
sliced by resin-bonded diamond wires can be employed for fabricating high-efficiency c-Si solar cells when the
cleaning and surface texture processes are properly optimized. The diamond wire sawing has been proved to be
promising as a next generation slicing process for c-Si solar cells.

description: Scarcity of indium and tellurium has been highlighted as a potential barrier for Cadmium Telluride
(CdTe) and Copper Indium Gallium (di)Selenide (CIGS) thin film technologies to achieve both large scale
deployment and reduction in production costs. With the aim of assessing the relative weight of the above concerns, a
review of existing literature on materials availability for PV technologies is presented and discussed, highlighting the
high uncertainty behind in the estimates of indium and tellurium constrained CdTe and CIGS PV potential. A
breakdown of CdTe and CIGS module production costs is also provided, accounting for the relative share of each
component materials over total module cost. Conditions affecting usage of the key materials in CdTe and CIGS
technologies are weighted against potential future indium and tellurium price escalation to provide a fuller picture of
production cost implications for the thin film PV technologies. This includes exploring and quantifying the potential
for innovation and technological developments (including efficiency increase, reduced absorber layer, higher material
utilization during deposition process) to ease the impact of possible future indium and tellurium supply constraint and
price increase.

description: The print characteristics and electrical performance of a high solids front contact silver paste approaching
90 percent total solids is compared to one with three percent lower solids. High solids paste is also compared to Hot
Melt and print-on-print or double printing techniques. The resultant aspect ratio increase for high solids compared to
standard or low solids is a minimum of 30 percent. Hot Melt and print-on-print or double printing techniques can
achieve an additional 70 percent gain. The aspect ratio gains increase the relative electrical performance from
approximately 3.5 to six percent compared to standard solids paste, respectively. In all cases the main contributing
factor to electrical performance gain is a decrease in series resistance leading to fill factor increases. High solids pastes
do not require changes to conventional screen printing processes. Hot Melt reduces overall capital equipment costs by
eliminating dryers and increases utilization yet requires minor printer and screen modifications in order to operate at
elevated temperatures. Print-on-Print or double printing increases capital equipment and operating costs due to material
consumption and necessitates sophisticated print alignment yet enables front contact engineering as there are two discrete
paste layers.
