Subjects: Uncategorized

description: Innovation and strategy are central issues for businesses operating in an ever increasingly competitive market place. For many firms the pursuit of a sustained competitive advantage through strategy is the focus of senior leadership. A key driver of this focus is the firms’ capability to innovate. This research demonstrates that the pursuit of a sustained competitive advantage, firm performance and long-term growth can be achieved through strategies focused on innovation capabilities (IC) development. The author cites literature which argues there are two, three or four innovation capabilities strategies based on Schumpeter (1934). However, the author argues, that there are five distinct innovation capability strategies that are interdependent, based on resource interdependencies and are essential to an overall firm strategy.The research employs an extensive literature review, leader interviews and quantitative analysis of data collected from an industry survey to highlight the significant factors influencing a firms IC. The findings of this research provide empirical support for five distinct Innovation Capabilities strategies, as well as supporting interdependence between the five strategies. Additionally, support was found for three outcomes tested. For Business the implication is that interdependencies between distinct innovation capabilities resources and strategies can either support or adversely affect outcome performance where interdependencies between resources and strategies is not fully understood. From a theoretical perspective, this study tests the combination and application of Resource-based View and Social Interdependence theories and proposes a less classical perspective of RBV as well as a combination of RBV with SI theory in extending IC research of the firm.
USING SERIOUS GAMES DESIGNED THROUGH THE GAME ELC+ FRAMEWORK TO ENHANCE DEEP LEARNING IN HUMAN RESOURCES DEVELOPMENT
Creators: name: Gemade, Mamfe-ter
Publisher: name: University of Westminster
Year: 2022

description: The traditional method of learning has been widely criticised for its limitations and inflexibility to application in non-educational settings. These observations about the traditional modes of learning have necessitated the contemplation and discovery of new approaches embracing technological tools that advances better learning experiences. Hence, new technological innovations, such as Stronger Game or Serious Games (SGs) have been embraced as more effective methods of achieving deep learning. The application of serious game has indeed, gained traction in both the formal educational and human resource (HR) settings, especially for employees’ training and development. Thus, the core question of this PhD research is hinged on whether the SGs are more effective in creating deep learning in adult learners, compared to the more traditional teaching methods. To respond to this query, the study examines the traditional and SGs learning approaches, in order to ascertain which is more effective in creating deep learning in adults, in addition to achieving human resource training and development. To guide the design and development of SGs to support adult DL, this research proposes a pedagogical framework referred to as the Game ELC+ framework that comprises four learning theories namely: The Game (Elements) within the Yu Kai Chou's Octalysis Framework; Bloom Taxonomy’s Player (Learning) Levels; (Cognitive) Theory of Multimedia Learning; and the Ruskov’s four evidence of Deep Learning (+). This framework provides the standard for measuring DL in the design of SGs. The research instruments developed include a traditional andragogical test which uses e-Learning materials containing ten different learning scenarios in the context of workplace HR scenarios, and a digital Serious Game using exactly the same content and scenarios with the traditional andragogical test. ANOVA was utilized as the data analytical approach for comparing the mean score of learners using serious games and the tradition eLearning platforms. The study hypothesised that deep learning can be achieved through the SGs and that it is more effective than the traditional andragogy. It further asserts that participants who used the SGs achieved a higher learning outcome than participants in traditional process. Participant observation during the testing phase suggests that the participants interacting with the SGs demonstrated high level of engagement and curiosity, when compared to participants who used the traditional eLearning platform. The study findings validate the hypotheses. By implication, the SGs designed according to the Game ELC+ framework results in improved learning outcomes. In summary, the findings claim that incorporating SG elements in HR training and development can improve professional practices and mitigate some of the challenges experienced by human resource in the traditional learning environment.

description: This qualitative study highlights Thai primary teachers thinking about, and experiences of, formative assessment in primary science classroom. The analysis captured Thai primary teachers’ understanding of the complex nature of formative assessment, which is best described as a continuum moving from simple to more complex. Additionally, the analysis revealed a range of factors influencing Thai primary teachers’ decision to implement formative assessment practices. Embedded assessment practices, driven by Thai cultural aspects and teachers’ perspectives about learning and teaching science, should be considered as a way forward to best support Thai students science learning.

description: We introduce a two-orbital Hamiltonian on a square lattice that contains on-site attractive interactions involving the two $e_g$ orbitals. Via a canonical mean-field procedure similar to the one applied to the well-known negative-$U$ Hubbard model, it is shown that the new model develops $d$-wave ($B_{1g}$) superconductivity with nodes along the diagonal directions of the square Brillouin zone. This result is also supported by exact diagonalization of the model in a small cluster. The expectation is that this relatively simple attractive model could be used to address the properties of multiorbital $d$-wave superconductors in the same manner that the negative-$U$ Hubbard model is widely applied to the study of the properties of $s$-wave single-orbital superconductors. In particular, we show that by splitting the $e_g$ orbitals and working at three-quarters filling, such that the $x^2-y^2$ orbital dominates at the Fermi level but the $3z^2-r^2$ orbital contribution is nonzero, the $d$-wave pairing state found here phenomenologically reproduces several properties of the superconducting state of the high $T_c$ cuprates.

description: Recently the mathematical formalism of quantum mechanics, especially methods of quantum probability theory, started to be widely used in a variety of applications outside of physics, e.g., cognition and psychology as well as economy and finances. To distinguish such models from genuine quantum physical models, they often called quantum-like (although often people simply speak about, e.g., "quantum cognition"). These novel applications generate a number of foundational questions. Nowadays we can speak about a new science - foundations of quantum-like modeling. At the first stage this science was mainly about comparison of classical and quantum models, mainly in the probabilistic setting. It was found that statistical data from cognitive psychology violate some basic constraints posed on data by classical probability theory (Kolmogorov, 1933); in particular, the constraints given by the formula of total probability and Bell's type inequalities. Recently another question attracted some attention. In spite of real success in applications, there are no reason to believe that the quantum probability would cover completely all problems of, e.g., cognition. May be more general probability models have to be explored. A similar problem attracted a lot of attention in foundations of quantum physics culminating in a series of experiments to check Sorkin's equality for the triple-slit experiment by Weihs' group. In this note we present a similar test in the cognitive experimental setting. Performance of this test would either give further confirmation of the adequacy of the quantum probability model to cognitive applications or rejection of the conventional quantum model. Thus this note opens the door for a series of exciting experimental tests for the quantum-like model of cognition.

description: In this talk, I will show the discovery prospects of Axion-like particle (ALP) at CE𝜈NS experiments. We consider the ALPs that couples to the standard model through the \(a \gamma \gamma\) interaction. The CE𝜈NS experiments, utilizing reactors and high-intensity proton beam at stopped pion experiments, produce a large number of photons that will be converted to ALPs via the Primakoff process in the target/core. We find that the current facilities at CE𝜈NS experiments can provide constraints on the unexplored parameter space compared to existing/future ALP experiments.

description: Dangerous damage to mitochondrial DNA (mtDNA) can be ameliorated during mammalian development through a highly debated mechanism called the mtDNA bottleneck. Uncertainty surrounding this process limits our ability to address inherited mtDNA diseases. We produce a new, physically motivated, generalisable theoretical model for mtDNA populations during development, allowing the first statistical comparison of proposed bottleneck mechanisms. Using approximate Bayesian computation and mouse data, we find most statistical support for a combination of binomial partitioning of mtDNAs at cell divisions and random mtDNA turnover, meaning that the debated exact magnitude of mtDNA copy number depletion is flexible. New experimental measurements from a wild-derived mtDNA pairing in mice confirm the theoretical predictions of this model. We analytically solve a mathematical description of this mechanism, computing probabilities of mtDNA disease onset, efficacy of clinical sampling strategies, and effects of potential dynamic interventions, thus developing a quantitative and experimentally-supported stochastic theory of the bottleneck.

description: The design of anisotype heterojunctions with an n-type wide band gap emitter layer (GaInP, AlInP or
AlGaAs) and a p-type GaAs base layer was analyzed for application as a middle subcell of multijunction cells.
Theoretical estimations made by numerical simulations have demonstrated that, when performance of conventional GaAs
homojunction subcell is limited by the charge carrier recombination in an n+ GaAs emitter, the proposed design could
increase the open circuit voltage as well as the cell efficiency. The influence of the defect density at the wide gap
emitter/base heterointerface on the solar cell performance was also analyzed. The efficiency of n-AlInP/p-GaAs and n-
AlGaAs/p-GaAs heterojunctions was shown to be independent of the interface density of states up to the value of 1011
cm-2 eV-1 (for the capture cross section value equal to 10-14 cm2). This fact makes them attractive for application in high
efficiency solar cells. In contrary, the n-GaInP/p-GaAs heterojunction exhibits a strong sensitivity of the efficiency to the
interface states that can limit its application.

description: This study adopted design-based research methodology to investigate processes involved in primary teachers learning sophisticated instructional practices through onsite collaborative professional learning experiences. Teaching and learning mental computation with conceptual understanding provided the context for studying ten teachers across three different school settings in Australia. Multiple qualitative data were collected. The study found that when teachers view themselves as learners; are situated within an innovative, supportive learning community; and given opportunities to engage in collaborative professional learning experiences attuned to a developing shared vision for effective teaching of mathematics, opportunities for teacher learning and change are enhanced.

description: The formation mechanism of brown dwarfs (BDs) is one of the long-standing problems in star formation because the typical Jeans mass in molecular clouds is too large to form these substellar objects. To answer this question, it is crucial to study a BD at the embedded phase. IRAS 16253-2429 is classified as a very low luminosity object (VeLLO) with internal luminosity 0.1 Lsun. VeLLOs are believed to be very low-mass protostars or even proto-BDs. We observed the jet/outflow driven by IRAS 16253-2429 in CO (2-1), (6-5), and (7-6) using the IRAM 30 m and APEX telescopes and the SMA in order to study its dynamical features and physical properties. Our SMA map reveals two protostellar jets, indicating the existence of a proto-binary system as implied by the precessing jet detected in H2 emission. We detect a wiggling pattern in the position-velocity diagrams along the jet axes, which is likely due to the binary orbital motion. Based on this, we derive the current mass of the binary as ~0.032 Msun. Given the low envelope mass, IRAS 16253-2429 will form a binary that probably consist of one or two BDs. Furthermore, we found that the outflow force as well as the mass accretion rate are very low based on the multi-transition CO observations, which suggests that the final masses of the binary components are at the stellar/substellar boundary. Since IRAS 16253 is located in an isolated environment, we suggest that BDs can form through fragmentation and collapse like low-mass stars.

description: We compare the outdoor performance of two polycrystalline-Si PV modules of identical design, but
with cells based on different types of solar-grade Silicon. The cells of one of the modules are made of Si feedstock
purified in the conventional chemical route, whereas the other module has cells based on solar Si produced from a
pyrometallurgical route. Electrical and electronic parameters of the modules are extracted from measured currentvoltage
data and compared. The two modules perform similarly in the Nordic conditions at which they have been
tested. Only minor differences are found between their electrical parameters. Analysis of the electronic parameters
related to p-n junction quality reveals the general similarity of the two materials, but also indicate subtle differences.

description: One of the limitations of conventional Czochralski process is the use of a high melt level to grow large
silicon charges. The increase in the melt level will increase the turbulence in the fluid thus limiting the growth rate.
In the continuous Cz process (CCz), lower melt levels can be used. In this work, turbulence phenomena are analyzed
by means of numerical simulations for several melt levels. The simulations confirm that shallow melts significantly
reduce turbulence and can be used when developing the CCz process.

description: Since its inception, underwater digital acoustic communication has required custom hardware that neither has the economies of scale nor is pervasive. We present the first acoustic system that brings underwater messaging capabilities to existing mobile devices like smartphones and smart watches. Our software-only solution leverages audio sensors, i.e., microphones and speakers, ubiquitous in today's devices to enable acoustic underwater communication between mobile devices. To achieve this, we design a communication system that in real-time adapts to differences in frequency responses across mobile devices, changes in multipath and noise levels at different locations and dynamic channel changes due to mobility. We evaluate our system in six different real-world underwater environments with depths of 2-15 m in the presence of boats, ships and people fishing and kayaking. Our results show that our system can in real-time adapt its frequency band and achieve bit rates of 100 bps to 1.8 kbps and a range of 30 m. By using a lower bit rate of 10-20 bps, we can further increase the range to 100 m. As smartphones and watches are increasingly being used in underwater scenarios, our software-based approach has the potential to make underwater messaging capabilities widely available to anyone with a mobile device.

description: 24th European Photovoltaic Solar Energy Conference, 21-25 September 2009, Hamburg, Germany; 1277-1280
description: A major waste of silicon (Si) occurs during photovoltaic (PV) production at the wafering stage, where
up to 50% of the Si ends up in the swarf as a disposal problem. The purpose of this work is to demonstrate that the
Fixed Abrasive Slicing Technique (FAST) for slicing wafers can be used to allow much of this swarf to be recycled
thereby reducing the cost and environmental impact of PV. Unlike conventional multi-wire slurry (MWS) saws, in
FAST, the diamond abrasive is fixed to the wires, and does not mix with and contaminate the swarf. The diamonds
also protect the wire from wear and limit the contamination of the Si swarf by the metal wire. We have sliced Si by
FAST, recovered and characterized the swarf. Based on these results, large amounts of swarf simulant were made
from high purity Si powders. This swarf simulant was then processed pyrometallurgically to produce Si feedstock.
The feedstock was analyzed, and is shown to have average resistivity of 1.9 Ohm*cm. The highest level of impurity
was Al at 0.58 ppmw. All other impurities were below 0.1 ppmw.
Functional data analysis for density functions by transformation to a Hilbert space

Year: 2016
Subjects: subject: Statistics Theory (math.ST)

description: Functional data that are nonnegative and have a constrained integral can be considered as samples of one-dimensional density functions. Such data are ubiquitous. Due to the inherent constraints, densities do not live in a vector space and, therefore, commonly used Hilbert space based methods of functional data analysis are not applicable. To address this problem, we introduce a transformation approach, mapping probability densities to a Hilbert space of functions through a continuous and invertible map. Basic methods of functional data analysis, such as the construction of functional modes of variation, functional regression or classification, are then implemented by using representations of the densities in this linear space. Representations of the densities themselves are obtained by applying the inverse map from the linear functional space to the density space. Transformations of interest include log quantile density and log hazard transformations, among others. Rates of convergence are derived for the representations that are obtained for a general class of transformations under certain structural properties. If the subject-specific densities need to be estimated from data, these rates correspond to the optimal rates of convergence for density estimation. The proposed methods are illustrated through simulations and applications in brain imaging.

distribution of the sawing particles has been investigated. Additionally the influence of both parameters on the wafer
surface quality has been analyzed.

description: We propose a class of multidimensional higher derivative theories of gravity without extra real degrees of freedom besides the graviton field. The propagator shows up the usual real graviton pole and extra complex conjugates poles that do not contribute to the absorptive part of the physical scattering amplitudes. Indeed, they may consistently be excluded from the asymptotic observable states of the theory making use of the Lee-Wick and Cutkoski, Landshoff, Olive and Polkinghorne prescription for the construction of a unitary S-matrix. Therefore, the spectrum consists on the graviton and short lived elementary unstable particles that we named "anti-gravitons" because of their repulsive contribution to the gravitational potential at short distance. However, another interpretation of the complex conjugate pairs is proposed based on the Calmet's suggestion, i.e. they could be understood as black hole precursors long established in the classical theory. Since the theory is CPT invariant, the complex conjugate of the micro black hole precursor has received as a white hole precursor consistently with the t'Hooft complementary principle. It is proved that the quantum theory is super-renormalizable in even dimension, i.e. only a finite number of divergent diagrams survive, and finite in odd dimension. Furthermore, turning on a local potential of the Riemann tensor we can make the theory finite in any dimension. The singularity-free Newtonian gravitational potential is explicitly computed for a range of higher derivative theories. Finally, we propose a new super-reneromalizable or finite Lee-Wick standard model of particle physics.

The aim of the research is to increase understanding of youth mentoring outcomes and processes in an Australian context. The quantitative results indicate that mentoring yields positive outcomes for youth in social-emotional skills, relationships with others and school engagement. The qualitative results add context and suggest that the sequencing of relationship development and goal-oriented activities is important in determining program effectiveness at an individual level.

description: As the price of photovoltaic (PV) electricity approaches grid parity, the potential explosion in demand
for PV means that the solar grade silicon (SoG Si) industry will need a rapidly scaleable, inexpensive and less

Si by a slagging/gettering technique promises such a rapidly scaleable process. We have demonstrated reduction of
phosphorus (P) in MG Si from 26 ppm to 0.51 ppm and a reduction of boron (B) from 19 ppm to 7 ppm using just
such a process.

description: The system presented in this work shows good repeatability (0.5%) and high accuracy in the computer
controlled spectral characterization of photovoltaic devices by the determination of internal quantum efficiency over an
extended wavelength range. Biasing conditions (for both light and voltage) are fully controlled by computer as well. A
corresponding I-V curve can be obtained in the same location without moving the sample on a different set-up. Scanning
images (maps) of internal quantum efficiency (IQE) and of external quantum efficiency (QE) can be obtained with high
spatial resolution. This sequence of maps demonstrates the capability of the system to perform multispectral imaging of
PV structures. I-V curves can be obtained in monochromatic or white light in same location as IQE curves without a
supplemental repositioning. Parameters extracted from I-V curves can be mapped with the same high spatial resolution.
Because IQE curves and I-V curves are obtained in the same location and using the same optics, a full characterization of
the photovoltaic device under test is possible in a single run. This system will have a wide range of application in
photovoltaics both research and production as it provides high accuracy and extended versatility.

description: In this work we have investigated several problems that may appear during the growth of strain balanced
quantum dots for high efficiency solar cells. We have used in situ stress measurements to evaluate the total stress
introduced by the InAs quantum dots and the exact composition and thickness of the GaAsP stress compensating barrier.
We have found that the quality of perfectly balanced samples can degrade as we stack the quantum dot layers (even for a
reduced number of them) leading, eventually, to a complete suppression of the quantum dot formation. We attribute this
effect to a strong strain modulation at the surface of the sample that leads to the migration of phosphorus adatoms away
from the top of the quantum dots, increasing the inhomogeneity of the compensating barrier. We conclude that using a
pure binary material as compensating layer would prevent this decomposition and lead to better material quality.

description: Hydrogenated silicon nitride thin films are an important technology for improving the efficiency and economics of crystalline silicon solar cells. Our group at General Plasma has developed an innovative new plasma
technology for plasma enhanced chemical vapor deposition (PECVD) of hydrogenated silicon nitride. This PECVD technology overcomes problems with electrode coating, poor uniformity and slow deposition rates associated with other PECVD platforms. The uniformity of deposited silicon nitride using our PECVD technology is +/- 3% over substrate widths exceeding 1 meter which is ideal for economical production of crystalline solar cells. In addition to uniform deposition over large area, our PECVD technology enables the control of refractive index, hydrogen bond density and Si-N bond density which are important for passivating defects as well as optical matching to n-type emitters of crystalline silicon solar cells [1] . In this work, we present an overview of the plasma source and thin film analysis of hydrogenated silicon nitride thin films that include FTIR, SIMS and UV-VIS-IR spectroscopic data and dielectric properties. The Resonant Coupled Photoconductivity Decay (RCPCD) technique is used to correlate carrier recombination lifetime to these properties [2].

description: We perform experiments and phase model simulations with a ring network of oscillatory electrochemical reactions to explore the effect of random connections and non-isochronocity of the interactions on the pattern formation. A few additional links facilitate the emergence of the fully synchronized state. With larger non-isochronicity, complex rotating waves or persistent irregular phase dynamics can derail the convergence to global synchronization. The observed long transients of irregular phase dynamics exemplify the possibility of a sudden onset of hyper synchronous behavior without any external stimulus or network reorganization.

description: We consider the SM extension with additional light real singlet scalar, right-handed neutrino and nonrenormalizable Yukawa interaction for the first two generations. We show that the proposed model can explain the observed $(g - 2)$ muon anomaly. Phenomenological consequences as flavour violating decays $τ\rightarrow μμμ, μμe, μe e $ are briefly discussed. We also propose the $U_R(1)$ gauge generalization of the SM with complex scalar singlet and nonzero right-handed charges for the first two generations.

description: We present a method to optimize qubit control parameters during error detection which is compatible with large-scale qubit arrays. We demonstrate our method to optimize single or two-qubit gates in parallel on a nine-qubit system. Additionally, we show how parameter drift can be compensated for during computation by inserting a frequency drift and using our method to remove it. We remove both drift on a single qubit and independent drifts on all qubits simultaneously. We believe this method will be useful in keeping error rates low on all physical qubits throughout the course of a computation. Our method is O(1) scalable to systems of arbitrary size, providing a path towards controlling the large numbers of qubits needed for a fault-tolerant quantum computer

description: Theories of intelligence have advanced significantly over the last 100 years, however we still complete cognitive ability tests much the same way as we always have. This thesis investigates newly developed items that measure four cognitive abilities, as defined by Cattell-Horn-Carroll (CHC) theory, known to be important for learning and how they can be utilised in a Computer Adaptive Test called the “CHC-CAT”. Such a test can be automated and only administers items to examinees that are required, in order to understand their ability. This is unlike conventional tests that administer all items in a linear fashion. Efficiencies of over 50% were obtained however further research is required to further increase reliability of the items.
Superconductivity in Tl_{0.6}Bi_{2}Te_{3} Derived from a Topological Insulator

description: Bulk superconductivity has been discovered in Tl_{0.6}Bi_{2}Te_{3}, which is derived from the topological insulator Bi2Te3. The superconducting volume fraction of up to 95% (determined from specific heat) with Tc of 2.28 K was observed. The carriers are p-type with the density of ~1.8 x 10^{20} cm^{-3}. Resistive transitions under magnetic fields point to an unconventional temperature dependence of the upper critical field B_{c2}. The crystal structure appears to be unchanged from Bi2Te3 with a shorter c-lattice parameter, which, together with the Rietveld analysis, suggests that Tl ions are incorporated but not intercalated. This material is an interesting candidate of a topological superconductor which may be realized by the strong spin-orbit coupling inherent to topological insulators.

description: The formation of a spin glass usually requires both structural disorder and frustrated magnetic interactions. Consequently, the origin of spin-glass behaviour in Y$_2$Mo$_2$O$_7$ $-$ in which magnetic Mo$^{4+}$ ions occupy a frustrated pyrochlore lattice with minimal compositional disorder $-$ has been a longstanding question. Here, we use neutron and X-ray pair-distribution function (PDF) analysis to develop a disorder model that resolves apparent incompatibilities between previously-reported PDF, EXAFS and NMR studies and provides a new and physical mechanism for spin-glass formation. We show that Mo$^{4+}$ ions displace according to a local "2-in/2-out" rule on each Mo$_4$ tetrahedron, driven by orbital dimerisation of Jahn-Teller active Mo$^{4+}$ ions. Long-range orbital order is prevented by the macroscopic degeneracy of dimer coverings permitted by the pyrochlore lattice. Cooperative O$^{2-}$ displacements yield a distribution of Mo$-$O$-$Mo angles, which in turn introduces disorder into magnetic interactions. Our study demonstrates experimentally how frustration of atomic displacements can assume the role of compositional disorder in driving a spin-glass transition.

description: We present a Ginzburg-Landau theory of micro phase separation in a bidisperse chiral membrane consisting of rods of opposite handendness. This model system undergoes a phase transition from an equilibrium state where the two components are completely phase separated to a microphase separated state composed of domains of a finite size comparable to the twist penetration depth. Characterizing the phenomenology using linear stability analysis and numerical studies, we trace the origin of the discontinuous change in domain size that occurs during this to a competition between the cost of creating an interface and the gain in twist energy for small domains in which the twist penetrates deep into the center of the domain.

description: Intermediate band solar cells (IBSCs) are a new kind of devices capable of surpassing the Shockley-
Queisser efficiency limit for conventional solar cells. This novel technology requires the use of a new type of
material named intermediate band (IB) material which makes a better use of the solar spectrum thanks to the
existence of a collection of electronic levels within the bandgap of the semiconductor. Quantum Dots (QDs) remain
as a feasible technology to implement IB materials. InAs/GaAs QD-IBSCs were manufactured in order to test the
validity of the concept, although their real size and shape are far from the optimum. This causes extra electron levels
to appear within the nanostructure confining potential, degrading the performance of the device. In this paper, the
effect of these extra levels will be studied through a multiple level IBSC model based on the detailed balance, but
modified so a term accounting for the non-radiative recombination (NRR) is also included. The model is completed
with constant fitting parameters so the concentration JL-VOC curves (which do not incorporate series resistance
effects) can be fitted. Several QD-IBSCs where manufactured, measured and fitted with this model, rendering
relevant information about the recombination nature of the QD-IBSCs.
