description: Conventional Transit Signal Priority (TSP) controls often reach the limitation for arterials accommodating heavy bus flows since the priority control function can significantly increase the delay at minor streets. Under such conditions, a proper signal coordinated plan that aims to offer progression for buses is one potentially effective strategy. This study proposes a bus-based progression system to reduce the delay of buses on local arterials experiencing heavy bus volume. The proposed model is capable of providing bus-progression bands under various traffic conditions, which take into account the stochastic nature of bus dwell time and the capacity of bus stops. The trade-off between passenger-car and bus-based progression bands and the selection logic under different traffic compositions have been also investigated in this study. The results of extensive simulation experiments have confirmed the proposed model's effectiveness in reducing the bus passenger delay and the average passenger-car delays under various traffic conditions.

description: We present spectroscopic observations of a sample of 72 emission-line objects, including mainly HII regions, in the spiral galaxy M 33. Spectra were obtained with the multi-object, wide field spectrograph AF2/WYFFOS at the 4.2m WHT telescope. Line intensities, extinction, and electron density were determined for the whole sample of objects. The aim of the present work was to derive chemical and physical parameters of a set of HII regions, and from them the metallicity gradient. Electron temperatures and chemical abundances were derived for the 14 HII regions where both [OII] and [OIII] emission line fluxes were measured, including the electron temperature sensitive emission line [OIII] 436.3 nm and in a few cases [NII] 575.5 nm. The ionization correction factor (ICF) method was used to derive the total chemical abundances. The presence of abundance gradients was inferred from the radial behaviour of several emission-line ratios, and accurately measured from chemical abundances directly derived in 14 HII regions. The oxygen abundances of our HII regions, located in the radial region from ~2 to ~7.2 kpc, gave an oxygen gradient -0.054+/-0.011 dex/kpc The overall oxygen gradient for M 33 obtained using ours and previous oxygen determinations in a large number of HII regions with direct electron temperature determination as well as abundance in young stars presented a two slope shape: -0.19 dex/kpc for the central regions (R<3kpc), and -0.038dex/kpc for the outer regions (R>=3kpc).

description: Over the last few years, a variety of different PV backsheet materials from various suppliers have
emerged in the PV market. Whilst some of these new products rely on well-known and established materials and
material combinations, others break new ground by introducing highly engineered new materials and concepts for the
use in photovoltaic applications. The aim of the work presented is to compare the performance of different
commercially available PV backsheet materials and material combinations regarding their stabilities under various
prolonged accelerated aging conditions (e.g.: UV-exposure, damp-heat testing) according to the internationally valid
standards (IEC 61730, IEC 61215, UL1703) but exceeding the requirements of those standards by a factor of 2 to 3
with respect to testing times and irradiation energy inputs. Key advantages as well as possible disadvantages of the
tested materials are discussed critically, focusing on safety and performance aspects of the backsheet setups under
evaluation.

The idempotents are found as evaluated products of certain rational functions thus providing a new version of the fusion procedure for the Hecke algebras. We show that the normalization factors which occur in the procedure are related to the Ocneanu--Markov trace of the idempotents.

description: The process of cascaded downconversion and sum-frequency generation inside an optical cavity has been predicted to be a potential source of three-mode continuous-variable entanglement. When the cavity is pumped by two fields, the threshold properties have been analysed, showing that these are more complicated than in well-known processes such as optical parametric oscillation. When there is only a single pumping field, the entanglement properties have been calculated using a linearised fluctuation analysis, but without any consideration of the threshold properties or critical operating points of the system. In this work we extend this analysis to demonstrate that the singly pumped system demonstrates a rich range of threshold behaviour when quantisation of the pump field is taken into account and that asymmetric polychromatic entanglement is available over a wide range of operational parameters.

Large PV Power Plants and Distributed PV: System Aspects and Grid Connection

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 3893-3895
description: There is great interest in integrating sources of electricity in buildings in order to get zero net energy
buildings. Building integrated PV (BIPV) is one suitable technology for reaching this purpose. In order to explore the
possibilities of BIPV, we have constructed a mock-up simulating a building and covered with a-Si thin film PV
modules. After one year of monitoring, the results show interesting features that make the façades and the roof work
in a complementary fashion. More precisely, there are a daily and a seasonal behavior that can make the energy
production fit the consumption. This is very important in some countries because the net metering scheme is expected
to include a toll for the energy exchanged with the grid, raising the costs and possibly making it economically
unprofitable.

description: The design of systems that can change their behaviour to account for scenarios that were not foreseen at design time remains an open challenge. In this paper we propose an approach for adaptation of mobile robot missions that is not constrained to a predefined set of mission evolutions. We propose applying the MORPH adaptive software architecture to UAVs and show how controller synthesis can be used both to guarantee correct transitioning from the old to the new mission goals while architectural reconfiguration to include new software actuators and sensors if necessary. The architecture brings together architectural concepts that are commonplace in robotics such as temporal planning, discrete, hybrid and continuous control layers together with architectural concepts from adaptive systems such as runtime models and runtime synthesis. We validate the architecture flying several missions taken from the robotic literature for different real and simulated UAVs.

description: In our previous work, ultrafast relaxation dynamics of photoexcitation in poly(3-hexylthiophene)
(P3HT) film was studied to determine the defect concentration. The present work was performed to study ultrafast
dynamics of the P3HT solutions in various solvents. The ultrafast dynamics was studied by using ultrashort sub-10fs
pulse, which resolves not only the electronic dynamics but also the vibration dynamics.
The electronic dynamics show fast and slow relaxations with time constants of ~200fs and ~3ps, respectively. The
faster time constant (~200fs) is thought be the speed of intrachain charge transfer to form a bound polaron pair in the
P3HT chain, and the time constant is longer when the dipole moment of the solvent is larger. The slower time
constant (~3ps) reflects the relaxation of the polaron pair also showing similar dependence on the dipole moment of
the solvent.
Linear prediction singular value decomposition method was used to estimate life time of the vibration modes. The
dependence on the dipole moment of the solvent was opposite in the vibration lifetime compared with that in the
electronic state lifetime. It shows that the vibration mode has strong interaction with the electronic excited state when
the dipole moment of the solvent is large.

description: Sparse code multiple access (SCMA), which helps improve spectrum efficiency (SE) and enhance connectivity, has been proposed as a non-orthogonal multiple access (NOMA) scheme for 5G systems. In SCMA, codebook design determines system overload ratio and detection performance at a receiver. In this paper, an SCMA codebook design approach is proposed based on uniquely decomposable constellation group (UDCG). We show that there are $N+1 (N \geq 1)$ constellations in the proposed UDCG, each of which has $M (M \geq 2)$ constellation points. These constellations are allocated to users sharing the same resource. Combining the constellations allocated on multiple resources of each user, we can obtain UDCG-based codebook sets. Bit error ratio (BER) performance will be discussed in terms of coding gain maximization with superimposed constellations and UDCG-based codebooks. Simulation results demonstrate that the superimposed constellation of each resource has large minimum Euclidean distance (MED) and meets uniquely decodable constraint. Thus, BER performance of the proposed codebook design approach outperforms that of the existing codebook design schemes in both uncoded and coded SCMA systems, especially for large-size codebooks.

description: To date Brazil’s electricity supply is highly dependent on hydro power. This is leading to economic
vulnerability in times of droughts and environmental as well as social problems due to the construction of hydro
power dams. Even though Brazil has got extremely favourable solar radiation conditions, PV has only played a minor
role in the country’s national energy mix. However, recent developments in the country are now paving the way for a
more prominent role of PV: Large scale grid-connected PV projects have been realised since 2011 and major sport
events like the Football World Cup in 2014 and the Olympic Games in 2016 are driving the PV development in
Brazil. Also the government and the Brazilian National Agency for Electric Energy (ANEEL) have recognised the
potential of PV for the country and implemented a new legislation to drive the PV market forward. With new PV
projects in the pipeline, a growing demand for stable and secure energy supply across all market segments and
increasing electricity prices together with falling LCOEs of PV plants, new PV market opportunities are opening up
in the biggest country in South America.

description: An exact expression is derived for the meson production current off the nucleon for real and virtual photons which cleanly separates, in a model-independent manner, a tree-level expression that manifestly preserves local gauge invariance in terms of a generalized Ward-Takahashi identity from transverse final-state-interaction (FSI) terms. As discussed in some detail, this exact formulation is particularly well suited for implementing approximation schemes of exchange-current and FSI contributions (which in practice generally will be necessary) at any level of sophistication without violating local gauge invariance.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 947-950
description: A very costly and thus important step in the solar cell production of crystalline silicon solar cells is the
cutting of wafers. The standard technique is the multi-wire sawing with abrasive SiC slurries. To reduce the costs
wafers will be cut thinner in the future to increase throughput and save raw materials. On the other hand the wafer
surface has to maintain at a very good level to prevent wafer breakage. Experiments for fast determination of the
sawing performance of different slurries were carried out using a lapping machine. Due to the same material removal
mechanism as in slurry sawing the results can be compared well. In this investigation the influence of the particle size
distribution and the particle shape on the material removal rate and surface roughness is studied. Special attention is
paid to the question, which particle fraction in a particle size distribution mainly affects the material removal rate.
Grits with an increased amount of a fine fraction and grits with additional coarser particles were tested and compared
to each other.
Searching for Nambu-Goldstone Bosons at the LHC

description: Phenomenological implications of a minimal extension to the Standard Model are considered, in which a Nambu-Goldstone boson emerges from the spontaneous breaking of a global U(1) symmetry. This is felt only by a scalar field which is a singlet under all Standard Model symmetries, and possibly by neutrinos. Mixing between the Standard Model Higgs boson field and the new singlet field may lead to predominantly invisible Higgs boson decays. The "natural" region in the Higgs boson mass spectrum is determined, where this minimally extended Standard Model is a valid theory up to a high scale related with the smallness of neutrino masses. Surprisingly, this region may coincide with low visibility of all Higgs bosons at the LHC. Monte-Carlo simulation studies of this "nightmare" situation are performed and strategies to search for such Higgs boson to invisible (Nambu-Goldstone boson) decays are discussed. It is possible to improve the signal-to-background ratio by looking at the distribution of either the total transverse momentum of the leptons and the missing transverse momentum, or by looking at the distribution of the azimuthal angle between the missing transverse momentum and the momentum of the lepton pair for the Z- and Higgs-boson associated production. We also study variations of the model with non-Abelian symmetries and present approximate formulae for Higgs boson decay rates. Searching for Higgs bosons in such a scenario at the LHC would most likely be solely based on Higgs to "invisible" decays.

description: The presented study provides a detailed insight for wet chemical texturing procedures of “cast-mono” or “mono-like” silicon substrates. Fundamental investigations establish the demand for adapted etching techniques in order to address the exceptional “cast-mono” surface properties. Fundamental evaluation parameters are texturing homogeneity, magnitude of effective surface reflectance and quality of produced texturing structures. The impact on solar cell characteristics, relevant processing steps and industrial application is discussed and interpreted with respect to material classifications and cost-effective manufacturing sequences.

description: A small number of anomalously bright boulders on the near-Earth, rubble-pile asteroid (101955) Bennu were recently identified as eucritic material originating from asteroid (4) Vesta. Building on this discovery, we explored the global presence of exogenic boulders on Bennu. Our analysis focused on boulders larger than 1 m that show the characteristic 1-micron pyroxene absorption band in the four-color MapCam data from the OSIRIS-REx mission. We confirm the presence of exogenic boulders similar to eucrites and find that mixtures of eucrites with carbonaceous material is also a possible composition for some boulders. Some of the exogenic boulders have spectral properties similar to those of ordinary chondrite (OC) meteorites, although the laboratory spectra of these meteorites have a higher albedo than those measured on Bennu, which could be explained by either a grain size effect, the presence of impact melt, or optical mixing with carbonaceous material owing to dust coating. Our Monte Carlo simulations predict that the median amount of OC mass added to the parent body of Bennu is 0.055% and 0.037% of the volume of a 100- and 200-km-diameter parent body, respectively. If Bennu was a uniformly mixed byproduct of parent body and S-type projectiles, the equivalent mass of OC material would be a sphere with a diameter of 36 to 40 m (or a volume of 24,200 to 33,600 m3). The total amount of OC material in the interior of Bennu estimated from the MapCam data is slightly higher (91,000-150,000 m3).

description: This paper describes the design and manufacturing of two innovative 2x4 cm2 III-V solar cells that
could have interesting relevance in the solar panel assembling for microsatellites. These two structures present the
advantages of the high efficiency achievable from the III-V compound solar cells and at the same time they do not
necessitate the protection bypass diode that is required for the manufacturing of solar assembly with standard triple
junction solar cells.The first device is based on a super single junction GaAs/Ge structure (named SSJ) that allows
efficiencies higher than 21%. The second solar cell (named SCTJ-25%) is a triple junction InGaP/GaAs/Ge device
protected by a shunt resistance instead of a bypass diode.
Both cells have been utilized by Surrey Satellite Technology Ltd (SSTL), the world leader for the manufacturing of
small satellites, for the realization of small solar panels that will be flight tested on the technology demonstrating
microsatellite TechDemoSat-1 (TDS-1), due to be launched at the beginning of 2013. TDS-1 flight heritage is
fundamental to prove the reliability of the two new solar cells operation in orbit.
The first part of the paper reports the electrical performance of the ENE/CESI super single junction gallium arsenide
cells and of CESI SCTJ25% triple junctions solar cells. Finally the SSTL solar cell assembly, the test panel features
and preliminary ground tests performed at panel level are presented.

description: Supervised learning, while prevalent for information cascade modeling, often requires abundant labeled data in training, and the trained model is not easy to generalize across tasks and datasets. It often learns task-specific representations, which can easily result in overfitting for downstream tasks. Recently, self-supervised learning is designed to alleviate these two fundamental issues in linguistic and visual tasks. However, its direct applicability for information cascade modeling, especially graph cascade related tasks, remains underexplored. In this work, we present Contrastive Cascade Graph Learning (CCGL), a novel framework for information cascade graph learning in a contrastive, self-supervised, and task-agnostic way. In particular, CCGL first designs an effective data augmentation strategy to capture variation and uncertainty by simulating the information diffusion in graphs. Second, it learns a generic model for graph cascade tasks via self-supervised contrastive pre-training using both unlabeled and labeled data. Third, CCGL learns a task-specific cascade model via fine-tuning using labeled data. Finally, to make the model transferable across datasets and cascade applications, CCGL further enhances the model via distillation using a teacher-student architecture. We demonstrate that CCGL significantly outperforms its supervised and semi-supervised counterparts for several downstream tasks.

description: We use the fluorescence effect of the lamination material of PV modules to detect cracks in waferbased
solar cells in a power plant. For this purpose the PV modules are irradiated by UV light and the fluorescence
light is measured by a camera. The measurement is realized in the dark. This new application of the fluorescence
method allows new insight to cracks of a huge amount of PV modules during service life without remounting or
touching the PV modules. We found that the frequency distribution of so-called “cross cracks” are almost
homogenous in the PV modules. These cracks are frequently induced by crumbs or needle-shaped production
equipment and not introduced after production. We show that the measured distribution of “cross cracks” in the PV
modules fits to the binominal frequency distribution, as it is expected for production induced cell failures. The
measured crack frequency distribution for other crack types is compared to a finite element simulation of a simplified
PV module. We find that the lateral crack distribution correlates with the simulated strain distribution induced by
module vibrations. In total we found that 4.1% of the solar cells in the PV modules show at least one crack.

description: The influence of the addition of sulfuric acid to the frequently-used HF-HNO3-H2O etching mixtures
has been studied. Nitrogen-oxygen cations, which are supposed to be crucial in the silicon oxidation process, are
stabilized by sulfuric acid. Raman spectroscopy is suitable for determination of intermediates and for the
quantification of bath components. The formation of nitrogen oxides during silicon etching was investigated in terms
of mixture composition. Etching multicrystalline silicon wafers in H2SO4-rich mixtures produces promising surface
textures. Etched wafer surfaces were investigated by means of laser scanning (LSM) and scanning electron
microscopy (SEM). Reflection measurements were performed to evaluate the novel surface textures.

description: The Shore hardness parameter is proposed as an analogue for the degree of cross-linking in ethylene
vinyl acetate (EVA) sheets. The parameter is measured for a series of EVA sheets, both individually and as part of a
mini-module. The gel content, which is another analogue of cross-linking, is measured using the Soxhlet test and
correlated with the hardness index. To obtain a range of cross-linking behaviors samples were cured for different
periods. It has been shown the Soxhlet measurement correlates with the Shore D0 hardness. We conclude that the
hardness test is a viable alternative to the Soxhlet measurement for PV-manufacture.

Equilibrium long-ranged charge correlations at the surface of a conductor coupled to the electromagnetic radiation

description: This study is related to the fluctuation theory of electromagnetic fields, charges and currents. The three-dimensional system under consideration is a semi-infinite conductor, modeled by the jellium, in vacuum. In previous theoretical studies it was found that the correlation functions of the surface charge density on the conductor decay as the inverse cube of the distance at asymptotically large distances. The prefactor to this asymptotic decay was obtained in the classical limit and in the quantum case without retardation effects. To describe the retarded regime, we study a more general problem of the semi-infinite jellium in thermal equilibrium with the radiated electromagnetic field. By using Rytov's fluctuational electrodynamics we show that, for both static and time-dependent surface charge correlation functions, the inclusion of retardation effects causes the quantum prefactor to take its universal static classical form, for any temperature.

title: Fostering Transformative Learning and Change in IBM Teams - An Action Research Inquiry
Creators: name: Edwards, Bronwyn
Publisher: name: University of Liverpool Repository
Year: 2024

description: Research Aim
During the research period I was an Organisation Development consultant in the Talent Transformation unit of IBM’s Global Business Services (business consulting) division. Having undergone a personal Transformative Learning experience due to working within a new form of operating model called IBM Garage, I became interested in exploring Transformative Learning in a team context.

Research Approach and Methodology
Building off of the foundation of a critical literature review, this research study uses an Action Research (AR) approach to foster a Team Transformative Learning (TTL) experience for IBM practitioners using the WeValue In Situ (WVIS) (Harder et al., 2021) method and process. Interpretive Phenomenological Analysis (IPA) was used to understand the lived experience of participants and whether this process might foster TL in the daily work of teams of IBM and clients, both as a catalyst for organisational change and as an improvement to the IBM Garage Operating Model. 

Findings 
WeValue In Situ (WVIS) has previously been tested by the authors (Harder et al., 2021) in a variety of different organisational models and structures, and now for this Action Research paper within IBM. WVIS may have generalisability to other organisations, with a few caveats: 
• the process is adhered to, as applied by qualified WVIS facilitator/s
• the scale is small – 4 to 6 participants is optimal, or more (up to a maximum of ~20) if the WVIS workshop is held face-to-face, not virtually.
Deep personal learning throughout the Action Research project resulted in a more reflective praxis, and a deeper understanding of the organisational political landscape, ultimately resulting in a move out of the IBM organisation in order to be able to effect organisational change better.

description: The traditional connection technic applied to solar cells requires an expensive metallization and can lead to cell
breakage because of mechanical stresses. Different alternatives, known as "low-stress", have been explored as reported by
several articles [1], [2], [3]. Laser spot soldering, adhesive and mechanical contacting technology relying purely on contact
pressure exerted by magnet or under pressure in the module interior have already been investigated and some of them are
starting to be used in production. Nevertheless all of these solutions have some drawbacks like for instance, one very sharp
process, costly material or components or bad interaction with other parts of the modules etc…
In this paper, we discuss a PV module with electrical contacts achieved through a resilient device. The main issue in this
simple approach concerns the pressure control which must stay consistent during all the 20 to 30 years of the module life.
Modeling and simulation allowed determining the mechanical characteristic and the theoretically architecture of the specific
elastic device. The Identification and characterization following routine durability tests of the adequate polymer is described
and results are commented. Two small modules with four cells have been mounted and tested with success but a thirty six
cells module failed during thermal cycling. Important details of implementation were revealed and taken into account in the
process improvement. Industrial design of a sixties cells module including the resilient device is explained and the
manufacturing process flow is described. The thermal cycling and exposure in natural environment was applied to this
module in order to prove the potential durability of this solution.
Partitioning sparse deep neural networks for scalable training and inference

description: The state-of-the-art deep neural networks (DNNs) have significant computational and data management requirements. The size of both training data and models continue to increase. Sparsification and pruning methods are shown to be effective in removing a large fraction of connections in DNNs. The resulting sparse networks present unique challenges to further improve the computational efficiency of training and inference in deep learning. Both the feedforward (inference) and backpropagation steps in stochastic gradient descent (SGD) algorithm for training sparse DNNs involve consecutive sparse matrix-vector multiplications (SpMVs). We first introduce a distributed-memory parallel SpMV-based solution for the SGD algorithm to improve its scalability. The parallelization approach is based on row-wise partitioning of weight matrices that represent neuron connections between consecutive layers. We then propose a novel hypergraph model for partitioning weight matrices to reduce the total communication volume and ensure computational load-balance among processors. Experiments performed on sparse DNNs demonstrate that the proposed solution is highly efficient and scalable. By utilizing the proposed matrix partitioning scheme, the performance of our solution is further improved significantly.

Subjects: subject: Astrophysics (astro-ph)

description: We report the detection of a new source of very high energy (VHE, E_gamma >= 100GeV) gamma-ray emission located close to the Galactic Plane, MAGIC J0616+225, which is spatially coincident with SNR IC443. The observations were carried out with the MAGIC telescope in the periods December 2005 - January 2006 and December 2006 - January 2007. Here we present results from this source, leading to a VHE gamma-ray signal with a statistical significance of 5.7 sigma in the 2006/7 data and a measured differential gamma-ray flux consistent with a power law, described as dN_gamma/(dA dt dE) = (1.0 +/- 0.2)*10^(-11)(E/0.4 TeV)^(-3.1 +/- 0.3) cm^(-2)s^(-1)TeV^(-1). We briefly discuss the observational technique used and the procedure implemented for the data analysis. The results are put in the perspective of the multiwavelength emission and the molecular environment found in the region of IC443.
