description: Abstract This paper reports the performance enhancement benefits in diamond turning of the silicon wafer by incorporation of the surface defect machining (SDM) method. The hybrid micromachining methods usually require additional hardware to leverage the added advantage of hybrid technologies such as laser heating, cryogenic cooling, electric pulse or ultrasonic elliptical vibration. The SDM method tested in this paper does not require any such additional baggage and is easy to implement in a sequential micro-machining mode. This paper made use of Raman spectroscopy data, average surface roughness data and imaging data of the cutting chips of silicon for drawing a comparison between conventional single-point diamond turning (SPDT) and SDM while incorporating surface defects in the (i) circumferential and (ii) radial directions. Complementary 3D finite element analysis (FEA) was performed to analyse the cutting forces and the evolution of residual stress on the machined wafer. It was found that the surface defects generated in the circumferential direction with an interspacing of 1 mm revealed the lowest average surface roughness (Ra) of 3.2 nm as opposed to 8 nm Ra obtained through conventional SPDT using the same cutting parameters. The observation of the Raman spectroscopy performed on the cutting chips showed remnants of phase transformation during the micromachining process in all cases. FEA was used to extract quantifiable information about the residual stress as well as the sub-surface integrity and it was discovered that the grooves made in the circumferential direction gave the best machining performance. The information being reported here is expected to provide an avalanche of opportunities in the SPDT area for low-cost machining solution for a range of other nominal hard, brittle materials such as SiC, ZnSe and GaAs as well as hard steels.

description: In times of social complexity and environmental crisis, such as the one that manifests today, a theory, a praxis, and a disposition for transdisciplinarity and dialogue, whose epistemological dimension is characterized by the multipolarity of fields of research and the interconnection of knowledge, are indispensable. Thus, this essay analyzes, in a transdisciplinary perspective, some works by the “street artist” Banksy that were reproduced in different places and reveal a concern for the common environment. These images, for reasons that will become clearer in the course of the work, are paradigmatic to try to understand both the problems of the environmental crisis experienced today and the idea of an intergenerational pact, taking both Hannah Arendt and Fritjof Capra’s thinking as the principles and rules of international environmental law and international human rights law.

Geology and genesis of the Mount Skukum tertiary epithermal gold-silver vein deposit, southwestern Yukon Territory (NTS 105D SW)
Creators: name: McDonald, Bruce Walter Robert
Publisher: name: University of British Columbia
Year: 2010

description: The Tertiary Mt. Skukum gold - silver epithermal vein deposit occurs 65 km southwest of Whitehorse in the Yukon Territory. Veins are hosted by a sequence of nearly flat-lying Eocene Skukum Group andesitic volcanic rocks of the Mt. Skukum Volcanic Complex, part of the Sloko Volcanic Province which unconformably overlies these intrusive complexes as well as metamorphic rocks of the Yukon Group. Major known mineralized zones occur within a regional halo of propylitic alteration centered on a fault-bounded graben within Main Cirque in the southwestern corner of the Mt. Skukum Volcanic Complex. Each zone consists of steeply-dipping quartz-carbonate-sericite veins associated with major faults and rhyolite dykes which bound blocks of the graben. Precious metals occur as electrum and native silver as fine grains averaging 15 to 20 microns and locaIly exceeding 1 mm across, in veins containing only trace amounts of sulphides. Fluid inclusions indicate that vein minerals were deposited from hydrothermal fluids averaging 313°C with an average salinity of 0.7 weight percent NaCl equivalent. Primary inclusions show that depositional fluids existed under two pressure regimes; one close to hydrostatic, the other approaching lithostatic. Both reflect depths of deposition of about 470 m below paleosurface. Variable fluid pressures reflecting similar depths of deposition combined with variable liquid to vapour ratios in primary inclusions as well as abundant textural evidence of hydrothermal brecciation indicate that boiling was common during mineralization. Oxygen and carbon isotope composition of minerals in the deposit and surrounding wall rocks indicate that depositional fluids were meteoric in origin with no contribution from magmatic sources. Large depletions in 0¹⁸ content of andesitic rocks in the deposit area indicate a minimum water rock ratio over the life of the deposit of 0.81:1. Precious metals at the Mt. Skukum deposit were emplaced at relatively low temperature in a near surface environment by a circulating, meteoric water dominated, hydrothermal system driven by a heat source associated with the rhyolite dykes. Gold, leached from andesitic volcanic rocks and metamorphic and granitic rocks was precipitated with quartz and carbonate in permeable conduits such as fault zones, and breccia bodies.

description: We report on the loading of large ion Coulomb crystals into a linear Paul trap incorporating a high-Finesse optical cavity (F~3200). We show that, even though the 3-mm diameter dielectric cavity mirrors are placed between the trap electrodes and separated by only 12 mm, it is possible to produce in situ ion Coulomb crystals containing more than 100.000 calcium ions of various isotopes and with lengths of up to several millimeters along the cavity axis. We show that the number of ions inside the cavity mode is in principle high enough to achieve strong collective coupling between the ion Coulomb crystal and the cavity field. The results thus represent an important step towards ion trap based Cavity Quantum ElectroDynamics (CQED) experiments using cold ion Coulomb crystals.

description: This paper presents a comparison between bifacial east-west vertical (EWV) and conventional south facing monofacial PV system in Nordic conditions. Special attention is given to the self-consumption rate reached at each system when residential loads are considered. Two test systems with bifacial EWV solar modules were installed, one on the rooftop of the premises at Turku University of Applied Sciences (TUAS) in Finland and another bifacial and monofacial system in Fairbanks, Alaska at the campus of the University of Alaska. System performance was monitored and recorded once per minute for post analysis. The real residential PV system at near proximity to the Turku test site was selected as a reference. The performance of the systems was monitored for a full calendar year in Finland and for two months in Alaska. This yield data is compared to the real-world residential load data collected earlier from the Turku region. As a result, the self-consumption rate of the systems can be calculated.
A representative particle approach to coagulation and fragmentation of dust aggregates and fluid droplets

Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: Context: There is increasing need for good algorithms for modeling the aggregation and fragmentation of solid particles (dust grains, dust aggregates, boulders) in various astrophysical settings, including protoplanetary disks, planetary- and sub-stellar atmospheres and dense molecular cloud cores. Here we describe a new algorithm that combines advantages of various standard methods into one. Aims: The aim is to develop a method that 1) can solve for aggregation and fragmentation, 2) can easily include the effect and evolution of grain properties such as compactness, composition, etc., and 3) can be built as a coagulation/fragmentation module into a hydrodynamics simulations. Methods: We develop a Monte-Carlo method in which we follow the 'life' of a limited number of representative particles. Each of these particles is associated with a certain fraction of the total dust mass and thereby represents a large number of true particles which all are assumed to have the same properties as their representative particle. Under the assumption that the total number of true particles vastly exceeds the number of representative particles, the chance of a representative particle colliding with another representative particle is negligibly small, and we therefore ignore this possibility. This now makes it possible to employ a statistical approach to the evolution of the representative particles. Results: The method reproduces the known analytic solutions of simplified coagulation kernels, and compares well to numerical results for Brownian motion using other methods. For reasonably well-behaved kernels it produces good results even for moderate number of swarms.

Effects of Unparticles on Running of Gauge Couplings

Publisher: name: arXiv
Year: 2007
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Unparticles charged under a gauge group can contribute to the running of the gauge coupling. We show that a scalar unparticle of scaling dimension d contributes to the βfunction a term that is (2-d) times that from a scalar particle in the same representation. This result has important implications on asymptotic freedom. An unparticle with d>2, in contrast to its matter counterpart, can speed up the approach to asymptotic freedom for a non-Abelian gauge theory and has the tendency to make an Abelian theory also asymptotically free. For not spoiling the excellent agreement of the standard model (SM) with precision tests, the infrared cut-off, m, of such an unparticle would be high but might still be reachable at colliders such as LHC and ILC. Furthermore, if the unparticle scale Λ_\calU is high enough, unparticles could significantly modify the unification pattern of the SM gauge couplings. For instance, with 3 scalar unparticles of d\sim 2.5 in the adjoint representation of the strong gauge group but neutral under the electroweak one, the three gauge couplings would unify at a scale of \sim 8\times 10^{12} {\rm GeV}, which is several orders of magnitude below the supersymmetric unification scale.

Unjust enrichment and the recovery of money mistakenly paid
Creators: name: Kaufmann, Manfred Max
Publisher: name: University of British Columbia
Year: 2010

description: In recent years, Canadian courts accepted the doctrine of unjust enrichment as a rationale underlying the law of restitution. This thesis adopts this approach, and examines its impact on questions adhering to the recovery of money mistakenly paid. The discussion is restricted to situations where no contractual obligations existed between the parties. After an introduction in chapter one, chapter two examines what the doctrine of unjust enrichment precisely predicates. Three particular aspects of the recovery of money mistakenly paid are then tackled: the action of the rightful payee, the availability of a remedial constructive trust and the defence of change of position. British and American law provide a background for the discussion. It will be seen that, with respect to restitutionary law, Canadian law has left its British ancestor behind and follows more the American model. The results arrived at are contrasted with the answers which a civil law code, more precisely, the German Civil Code, provides for the questions under review. The doctrine of unjust enrichment, according to this thesis, calls for the abolition of the action of the rightful payee. The doctrine does not necessarily entail the recognition of constructive trusts to remedy an unjust enrichment. However, the remedial constructive trust is a useful remedy for a mistaken payer and, if the payee has become bankrupt, the only one. Finally, it is argued that the recognition of change of position as a defence is a consequent step after the recognition of the unjust enrichment doctrine.

description: Lead halide perovskites constitute a promising material for various opto-electronic applications, most prominently photovoltaics. The organic-inorganic perovskites that have been mostly investigated for use as photovoltaic absorbers, e.g. MAPbI3, face two main issues that hinder their large-scale application: A lack of stability towards environmental factors and the fact that they contain lead. The double perovskite Cs2AgBiBr6 presents a significantly more stable and lead-free alternative. We present a dry vacuum synthesis of Cs2AgBiBr6 thin films by a two-stage co-evaporation process that leads to homogeneous layers with large crystals. Our first trials for their implementation as absorbers in solar cells yielded rectifying diodes, but only a low efficiency of 0.5 % (descending scan direction) due to very low current densities. The JV-curves of the double perovskites are compared to devices with a co-evaporated MAPbI3 absorber, with which we obtain an efficiency of 9.8 % (descending scan direction). Transmission electron microscopy of a cross-section of the Cs2AgBiBr6 solar cell reveals large grains in the micrometre-range. While the photoconversion efficiency seems limited, the homogenous, controlled deposition and good crystallinity of the obtained Cs2AgBiBr6 layers makes our preparation method attractive for other opto-electronic applications not depending on optical absorption, such as X-ray- and UV-detectors.

description: Besides the low-irradiance behavior and the temperature behavior, the angular transmittance of a photovoltaic (PV) module is a determining factor for its energy yield performance. The angular loss increases with the Angle of Incidence (AoI) and is described by the Incident Angle Modifier (IAM), which is the ratio of the PV device short circuit current (normalized to its Isc at normal incidence) and the cosine of AoI. Procedures for IAM measurement in the angular range of ±80° under natural sunlight and simulated sunlight are defined in the standard IEC 61853-2. In previous work, a solar simulator test method for full-size c-Si PV modules has been developed. It has been demonstrated that the IAM measurement must be related to the dimensions of a single solar cell to meet the technical requirements of IEC 61853-2. As single cells are not accessible in the PV module interconnection circuit a non-destructive test method was developed, which is based on partial shading of the test cell. This paper is a continuation of this work for thin-film PV modules in original size. The main difference to c-Si modules is that the sub-area required for IAM measurement cannot be related to a single cell, but must be related to a group of serially connected cells. Two test methods based on partial shading of a thin-film module have been studied, which both yield an IAM uncertainty better than ±0.01 in the angular range of ±75°. Comparative IAM measurements of commercial thin-film PV modules have shown only a slight variation of angular response curves. The associated spread in annual energy yield loss due to angular effects is less than 1% for the moderate climate of central Europe.

description: Upgraded Metallurgical-Grade (UMG) silicon is a promising low-cost feedstock material for silicon solar cells. However, UMG wafers are susceptible to high-temperature degradation due to the presence of a relatively high concentration of metallic (e.g., Fe, Cu, and Cr) and non-metallic impurities such as oxygen and carbon. In this case, high-temperature process steps such as boron diffusion and oxidation result in significant bulk degradation due to the formation of ring defects. This work aims to investigate the influence of high-temperature thermal processes on the formation of defects in n-type UMG-Cz wafers. Here, we focus on the thermal processes involved in the fabrication of single-boron diffusion and double-boron diffusion solar cells with phosphorus-doped polysilicon contacts on n-type UMG wafers. Using a combination of quasi-steady-state photoconductance lifetime testing, Fourier transform infrared spectroscopy for interstitial oxygen concentration measurement, and photoluminescence imaging, it is shown that the performance of the UMG-Cz solar cells was affected by the thermal budget used during the fabrication. With the tabula rasa step, the i-Voc of the UMG-Cz cells fabricated with single-boron diffusion increased from 650 mV to 690 mV. Further, the i-Voc of the tabula rasa treated UMG-Cz cells decreased to 630 mV after using double-boron diffusion process.

Sustainability and Recycling

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 964-973
description: Photovoltaics (PV) waste, associated to the exponentially growing PV installations on global scale, presents today an emerging environmental challenge, but also brings unprecedented and multifold value creation opportunities. In this context, significant PV business and R&D efforts shift towards establishing a more sustainable, environmentally friendly and economically viable end-of-life (EoL) management for PV modules; including recycling, recovery of raw materials, repair/refurbishment and even re-use of decommissioned or failed PV modules. In the CIRCUSOL project, PV partners aspire to formalize the repair/refurbish and re-use value chains in the PV industry and propose a circular business model, based on a Product-Service System (PSS). Towards these goals, this review study introduces the relevant research groundwork; a status overview and today’s R&D and business challenges in PV recycling, repair/refurbishment and re-certification aspects for second-life PV modules. The topics and the relevant reported literature are examined from both circular economy and technology perspective. The review indicates a considerable technological and operational know-how in PV EoL management, that already exists and continuously evolves in mature PV markets. On the other hand, R&D in repair/refurbishment of decommissioned and/or failed PV modules remains scarce; while, best practices and commercial services for reliability testing/recertification and trading of second-life PV modules are neither standardized nor consolidated into any product-service system or business model.

Homojunction Solar Cells

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 492-495
description: In our previous work, we demonstrated that an average efficiency of mass production of 21.35 % with the best efficiency of 21.70 % was achieved by using our unique printed-AlOx passivated emitter and rear cells (PERC) technology. We also found that the performance of the printed-AlOx PERC cell is sensitive to the flatness of rear surface and the efficiency of cells increases by improving the flatness of rear surface. In this work, we found that there is some limitation of efficiency gain by further increasing the rear-side polishing weight in our standard in-line process. Therefore, we proposed a batch-type process to use the phosphorous silicate glass (PSG) formed by the existing diffusion process as the front protective layer, and to directly polish the rear surface in the alkaline solution with the assistance of the functional additives. The wafer cleanliness was improved by using this batch-type process and it resulted in higher lifetime as well as efficiency than that by using the standard in-line process. However, this method is still not applicable to laser-doped selective emitter (LDSE) process due to the structure change of the PSG after laser treatment. We achieved an average efficiency of 21.54 % and the best efficiency of 21.79 % of the PERC cells by using this method. With this method’s feature of better wafer cleanliness, it stands a chance of reaching mass production efficiency over 21.80 % if it can be applicable to LDSE process in the future.

description: The Desktop Grid offers solutions to overcome several challenges and to answer increasingly needs of scientific computing. This technology consists mainly in exploiting PC resources, geographically dispersed, to treat time consuming applications and/or important storage capacity requiring applications. However, as resources number increases, the need for scalability, self-organisation, dynamic reconfiguration, decentralization and performance becomes more and more essential. In this context, this paper evaluates the scalability and performance of P2P tools for registering and discovering services (Publish/Subscribe systems). Three protocols are used in this purpose: Bonjour, Avahi and Pastry. We have studied the behaviour of these protocols related to two criteria: the elapsed time for registrations services and the needed time to discover new services.

The location of recent X-ray and gamma-ray emission (N14 W61) was near to Sun-Earth connecting magnetic field lines, thus providing the opportunity to directly observe the acceleration source from Earth. We restrict our analysis to protons of energy greater than 450 MeV to avoid complications arising from transport processes that can affect the propagation of low energy protons. In light of this revised approach we have reinvestigated two previous GLEs: those of 2000 July 14 (GLE 59) and 2001 April 15 (GLE 60). Within the limitations of the spectral forms employed, we find that from the peak (06:55 UT) to the decline (07:30 UT) phases of GLE 69, neutron monitor observations from 450 MeV to 10 GeV are best fitted by the Gallegos-Cruz & Perez-Peraza stochastic acceleration model. In contrast, the Ellison & Ramaty spectra did not fit the neutron monitor observations as well. This result suggests that for GLE 69, a stochastic process cannot be discounted as a mechanism for relativistic particle acceleration, particularly during the initial stages of this solar event. For GLE 59 we find evidence that more than one acceleration mechanism was present, consistent with both shock and stochastic acceleration processes dominating at different times of the event. For GLE 60 we find that Ellison & Ramaty spectra better represent the neutron monitor observations compared to stochastic acceleration spectra. The results for GLEs 59 and 60 are in agreement with our previous work.

description: Qualitative comparison of source sizes from pi-Xi correlations analyses in d+Au and Au+Au collisions at sqrt(s_NN)=200G GeV and sqrt(s_NN)=62 GeV is presented. For the most central Au+Au collisions at sqrt(s_NN)=200 GeV we report first quantitative results concerning size of the pi-Xi source and relative shift of the average emission points between pi and Xi showing that the homogeneity region of Xi source is smaller then that of pion and significantly shifted in the transverse direction.

description: We study the relaxation of a non-equilibrium carrier distribution under the influence of the electron-electron interaction in the presence of disorder. Based on the Anderson model, our Hamiltonian is composed from a single particle part including the disorder and a two-particle part accounting for the Coulomb interaction. We apply the equation-of-motion approach for the density matrix, which provides a fully microscopic description of the relaxation. Our results show that the nonequlibrium distribution in this closed and internally interacting system relaxes exponentially fast during the initial dynamics. This fast relaxation can be described by a phenomenological damping rate. The total single particle energy decreases in the redistribution process, keeping the total energy of the system fixed. It turns out that the relaxation rate decreases with increasing disorder.

description: We report muon spin relaxation measurements on two Ti3+ containing perovskites, LaTiO3 and YTiO3, which display long range magnetic order at low temperature. For both materials, oscillations in the time-dependence of the muon polarization are observed which are consistent with three-dimensional magnetic order. From our data we identify two magnetically inequivalent muon stopping sites. The muon spin relaxation results are compared with the magnetic structures of these compounds previously derived from neutron diffraction and muon spin relaxation studies on structurally similar compounds.

description: This paper investigates differences in returns between the ETF price, Net Asset Value, and Benchmark Asset Baskets for five popular futures-backed ETFs. We decompose tracking difference to examine the relative size of tracking differences attributable to managers versus the arbitrage process. Tracking differences attributable to managers is found to be significantly smaller than that attributable to the arbitrage process. We then test for average Tracking Differences using the Mincer-Zarnowitz Equation. We find evidence of bias in returns for multiple ETFs and demonstrate the usefulness of the decomposition. Furthermore, we investigate the dynamics of Tracking Error using a GARCH methodology. We find support that the volatility of the ETF effects Tracking Error but find no evidence that rolling futures contracts influences Tracking Error.
Gravitational waveforms for finite mass binaries

description: One of the promising sources of gravitational radiation is a binary system composed of compact stars. It is an important question how the rotation of the bodies and the eccentricity of the orbit affect the detectable signal. Here we present a method to evaluate the gravitational wave polarization states for inspiralling compact binaries with comparable mass. We consider eccentric orbits and the spin-orbit contribution in the case of one spinning object up to 1.5 post-Newtonian order. For circular orbits our results are in agreement with existing calculations.

Non-Hermitian Lindhard function and Friedel oscillations

description: The Lindhard function represents the basic building block of many-body physics and accounts for charge response, plasmons, screening, Friedel oscillation, RKKY interaction etc. Here we study its non-Hermitian version in one dimension, where quantum effects are traditionally enhanced due to spatial confinement, and analyze its behavior in various limits of interest. Most importantly, we find that the static limit of the non-Hermitian Lindhard function has no divergence at twice the Fermi wavenumber and vanishes identically for all other wavenumbers at zero temperature. Consequently, no Friedel oscillations are induced by a non-Hermitian, imaginary impurity to lowest order in the impurity potential at zero temperature. Our findings are corroborated numerically on a tight-binding ring by switching on a weak real or imaginary potential. We identify conventional Friedel oscillations or heavily suppressed density response, respectively.

description: We analyze the stability of non-ground nonlinear states of a Bose-Einstein condensate in the mean field limit in effectively 1D (``cigar-shape'') traps for various types of confining potentials. We find that nonlinear states become, in general, more stable when switching from a harmonic potential to an anharmonic one. We discuss the relation between this fact and the specifics of the harmonic potential which has an equidistant spectrum.
Study of the derivative expansions for the nuclear structure functions

description: We study the convergence of the series expansions sometimes used in the analysis of the nuclear effects in Deep Inelastic Scattering (DIS) proccesses induced by leptons. The recent advances in statistics and quality of the data, in particular for neutrinos calls for a good control of the theoretical uncertainties of the models used in the analysis. Using realistic nuclear spectral functions which include nucleon correlations, we find that the convergence of the derivative expansions to the full results is poor except at very low values of $x$.

Professional Applications of PV

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 1787-1791
description: This paper shows recent approaches of PV-powered vehicles applications. According to the NEDO’s Interim Report “PV-Powered Vehicle Strategy Committee,” new broader PV market with more than 10GW and 50GW in 2030 and 2050, respectively are expected to be established when PV-powered vehicles are developed. Cumulative PV capacity for PV-powered vehicles will be 50GW and 0.4TW in 2030 and 2050, respectively. According to our survey, the use of more than 30 % of high-efficiency PV enables 30 km per day driving without charging and the Japanese society that majority of the family cars run by the sun and without supplying gas. Thus, we are developing high-efficiency and low-cost solar cells and modules for automobile applications. In this paper, our analytical results for the efficiency potential of various solar cells for choosing candidates of high-efficiency solar cell modules for automobile applications. In addition to high-efficiency, 3-dimensional surface, color control, lightweight and low-cost are necessary for PV-powered applications. Approaches to automobile application by using III-V/Si tandem solar cells and static low concentration are also presented.These notes include important information on how to prepare and submit your paper.
