description: Many research groups have studied the operation of partially shaded photovoltaic (PV) systems during the past decades, and the well-known one-diode model of a PV cell has been mainly used to model the electrical behaviour of the PV systems. However, the effects of data sampling resolution have obtained little attention and even some meaningless results appear in the literature caused by unsuitable sampling resolution. In this paper, the effects of the length of a simulation time step, the resolutions of irradiance and I–U curves and the size of a basic simulation unit on the accuracy of the simulations of PV system operation under partial shading conditions were studied. The operation of PV systems was simulated by using the one-diode model of a PV cell. The
study aimed to find out adequate resolution for the simulation parameters to minimise the computing time while
retaining sufficient accuracy of the simulations. The study was based on the apparent velocity and other characteristics of 7880 irradiance transitions caused by moving clouds and identified in measured irradiance data. The results show that the accuracy of 1 W/m2 is sufficient for the irradiance and, accordingly, 1000 points for the I–U curves for PV string and array level partial shading studies.

description: This study introduces the National Renewable Energy Laboratory’s (NREL’s) recent efforts to extend the capability of the Fast All-sky Radiation Model for Solar applications (FARMS) by computing spectral solar irradiances over both horizontal and inclined surfaces. A new model is developed by computing the optical thickness of the atmosphere using SMARTS2, a spectral irradiance model for clear-sky conditions. A comprehensive lookup
table (LUT) of cloud bidirectional transmittance distribution functions (BTDFs) is precomputed for 2002 wavelength
bands using an atmospheric radiative transfer model, libRadtran. The solar radiation transmitted through the atmosphere is given by considering all possible paths of photon transmission and the relevant scattering and absorption attenuation. Our results indicate that this new model has an accuracy that is similar to that of state-of-theart radiative transfer models, but it is significantly more efficient.

description: We revisit the self-contained quantum refrigerator in the strong-internal-coupling regime by employing the quantum optical master equation. It is shown that strong internal coupling reduces the cooling ability of the refrigerator. In contrast to the weak-coupling case, strong internal coupling could lead to quite different and even converse thermodynamic behaviors.

description: Information management for PV power plants or renewable energy power plants in general is challenging. A holistic approach is required to ensure comprehensibility and interoperability of plant-related information. In November 2017, the German Institute for Standardization (DIN) is going to publish the new standard
DIN 77005-1 specifying general requirements for plant lifecycle records (PLR). The application of this standard using
a digital PLR provides significant opportunities for cost reductions in photovoltaics operation and maintenance (O&M)

Further, it is proved that given a graph $X,$ the characteristic polynomial of $N(X)$ divides the characteristic polynomial of $N(X^{\prime\prime}),$ where $X^{\prime\prime}$ denote the Kronecker double cover of $X.$

description: Under normal circumstances most members of the general relativity community focus almost exclusively on the local properties of spacetime, such as the locally Euclidean structure of the manifold and the Lorentzian signature of the metric tensor. When combined with the classical Einstein field equations this gives an extremely successful empirical model of classical gravity and classical matter --- at least as long as one does not ask too many awkward questions about global issues, (such as global topology and global causal structure). We feel however that this is a tactical error --- even without invoking full-fledged "quantum gravity" we know that the standard model of particle physics is also an extremely good representation of some parts of empirical reality; and we had better be able to carry over all the good features of the standard model of particle physics --- at least into the realm of semi-classical quantum gravity. Doing so gives us some interesting global features that spacetime should possess: On physical grounds spacetime should be space-orientable, time-orientable, and spacetime-orientable, and it should possess a globally defined tetrad (vierbein, or in general a globally defined vielbein/n-bein). So on physical grounds spacetime should be parallelizable. This strongly suggests that the metric is not the fundamental physical quantity; a very good case can be made for the tetrad being more fundamental than the metric. Furthermore, a globally-defined "almost complex structure" is almost unavoidable. Ideas along these lines have previously been mooted, but much is buried in the pre-arXiv literature and is either forgotten or inaccessible. We shall revisit these ideas taking a perspective very much based on empirical physical observation.

description: Given a hyperkahler manifold M, the hyperkahler structure defines a triple of symplectic structures on M; with these, a triple of Hamiltonians defines a so called hyperhamiltonian dynamical system on M. These systems are integrable when can be mapped to a system of quaternionic oscillators. We discuss the symmetry of integrable hyperhamiltonian systems, i.e. quaternionic oscillators; and conversely how these symmetries characterize, at least in the Euclidean case, integrable hyperhamiltonian systems.

Then, using our results, we give the unitary equivalence of this type of invariant subspace and a characterization of outer functions in $H^2(U^n)$.

description: Twenty-first-century learning demands increased recognition of the importance of children's oral language skills (Trilling & Fadel, 2009). To date, debate has centred around the use of digital technology and its effects on the sociocultural environment that develops children's oral language skills (Cordes & Miller, 2000; Kirkland & Patterson, 2005; Oakley, Pegrum, Faulkner, & Striepe, 2012). In many Australian communities, children are presenting at school with low oral language skills (Harrison, McLeod, Berthelsen, & Walker, 2009; Hill, 201 0), which will ultimately affect their literacy development throughout their lives (Hill & Launder, 201 0). Traditional interventions for oral language development have focused on parent-child interactions around books, games and conversations (Konza, 2011 ), but recent forms of digital technology have opened up a new pedagogical teaching and learning area, which remains relatively unexplored in the literature (Pegrum, Oakley, & Faulkner, 2013). This research study is situated in the qualitative paradigm, using case-study methodology to explore classroom and pre-service teachers' perceived views of using iPads to scaffold oral language development in the early years. The case study involved a partnership created between Northbridge Primary School and Monash University to facilitate the oral language development of children in Prep to Year 2. The iPad was one of the tools employed to scaffold and guide the development and learning. Four classroom teachers and seven pre-service teachers were interviewed to examine how, when, where and why iPads were being used in the classroom and, ultimately, what effect this technology was having on children's oral language skills. Factors affecting integration, pedagogical teaching and learning, teaching implications and engagement were a focus. Second-generation activity theory allowed for an analysis and discussion of the tensions and complexities that resulted from using iPads for oral language development. Findings suggest that the use of iPads for oral language development is mediated by teachers' personal and pedagogical beliefs. It is only by examining and acknowledging these beliefs that the complexities of using these devices for oral language development can be examined. Overall, it was discovered that when used as a collaborative pedagogical tool in the classroom, the iPad effectively scaffolds and develops the oral language skills of primary-school children.

description: The nonlinear Vlasov equation contains the full nonlinear dynamics and collective effects of a given Hamiltonian system. The linearized approximation is not valid for a variety of interesting systems, nor is it simple to extend to higher order. It is also well-known that the linearized approximation to the Vlasov equation is invalid for long times, due to its inability to correctly capture fine phase space structures. We derive a perturbation theory for the Vlasov equation based on the underlying Hamiltonian structure of the phase space evolution. We obtain an explicit perturbation series for a dressed Hamiltonian applicable to arbitrary systems whose dynamics can be described by the nonlinear Vlasov equation.

description: Energy-loss magnetic chiral dichroism (EMCD) allows for the quantification of magnetic properties of materials at the nanometer scale. It is shown that with the support of simulations that help to identify the optimal conditions for a successful experiment and upon implementing measurement routines that effectively reduce the noise floor, EMCD measurements can be pushed towards quantitative magnetic measurements even on individual nanoparticles. With this approach, the ratio of orbital to spin magnetic moments for the Fe atoms in a single L$1_0$ ordered FePt nanoparticle is determined to be ${m_l}/{m_s} = 0.08 \pm 0.02$. This finding is in good quantitative agreement with the results of XMCD ensemble measurements.

description: Most teachers incorporate some form of information and communication technologies (ICT) into their teaching and learning practice. This study reviews teachers' overall perceptions of ICT, including their views on professional development, barriers they encounter and successes they have achieved. The study was undertaken at an Australian private school, with 39 online questionnaire participants and 4 interviewees. The data suggested that teachers have a positive perception towards the benefits of ICT integration in their school administration and into their classrooms, however, there is a negative perception regarding the ongoing obstacles teachers encounter in gaining appropriate or relevant professional development and on ICT integration.

description: In Australia there are two entry levels in nursing, Registered Nurse (RN) and Enrolled Nurse (EN). Whilst much of the focus of nursing education research is attentive to RN and postgraduate nursing students (higher education), the educational preferences of EN students has not been recognised or identified previously. EN students in the Vocational Education and Training (VET) setting as learners have unique educational needs. As learners, EN students are diverse in terms of learner characteristics and background. Despite these important considerations there does not appear to be the targeted attention in educational learning methodology to support learner preferences in the planning and delivery of nursing education for EN students. This research identifies specific learner preferences for teaching modalities among EN students in the Diploma of Nursing program. A qualitative research methodology using an explorative descriptive approach in the naturalistic setting has been adopted for this study. The study was set in a private Registered Training Organisation (RTO). Data was collected through focus group discussions with data analysis involving a thematic framework. Five main themes were identified through the thematic analysis; variety of teaching and assessment methods, educator directed or guided learning, practical application and simulated learning, face to face learning and closer integration of theory to clinical practicum. This research recognises specific learning needs of EN students from the learner's perspective. The knowledge generated from this study will help guide future planning strategies in teaching and learning education for the Diploma of Nursing (EN) program.

description: During the commissioning of the Gemini MCAO System (GeMS), we had the opportunity to obtain data with the Gemini Multi-Object Spectrograph (GMOS), the most utilised instrument at Gemini South Observatory, in March and May 2012. Several globular clusters were observed in imaging mode that allowed us to study the performance of this new and untested combination. GMOS is a visible instrument, hence pushing MCAO toward the visible.We report here on the results with the GMOS instruments, derive photometric performance in term of Full Width Half Maximum (FWHM) and throughput. In most of the cases, we obtained an improvement factor of at least 2 against the natural seeing. This result also depends on the Natural Guide Star constellation selected for the observations and we then study the impact of the guide star selection on the FWHM performance.We also derive a first astrometric analysis showing that the GeMS+GMOS system provide an absolute astrometric precision better than 8mas and a relative astrometric precision lower than 50 mas.

description: A new, so called odd Gel'fand-Zetlin basis is introduced for the irreducible covariant tensor representations of the Lie superalgebra gl(n|n). The related Gel'fand-Zetlin patterns are based upon the decomposition according to a particular chain of subalgebras of gl(n|n). This chain contains only genuine Lie superalgebras of type gl(k|l) with k and l nonzero (apart from the final element of the chain which is gl(1|0)=gl(1)). Explicit expressions for a set of generators of the algebra on this Gel'fand-Zetlin basis are determined. The results are extended to an explicit construction of a class of irreducible highest weight modules of the general linear Lie superalgebra gl(\infty|\infty).

Exploring the relationship between motivation for becoming a therapist and empathy

description: It is increasingly accepted that the self of the therapist influences the process and outcome of therapy. To extend the field, the current study addressed calls in existing literature to (a) increase understanding of what motivates individuals to become therapists, and (b) map the occupational prognoses of those entering the profession, by providing the first empirical study to investigate: What, if any, is the relationship between therapists’ motivation for becoming a therapist, and the process and consequences of their empathy, and how can it be explained? Informed by a grounded theory framework and mixed methods design, findings from thematic analysis (N = 9) supplemented with correlational data and multiple hierarchical regressions (N = 226), generated the model of sharing therapy, you, me, and empathy (tyme-share). This model suggests that increased self-awareness with regards to personal vulnerability and motivation for becoming a therapist was related to the likelihood that an individual therapist would resonate emotionally with clients when empathising. In turn, the willingness to emotionally resonate with clients decreased the likelihood of deleterious therapeutic consequences for therapists such as reduced self-care, unrealistic appraisals of responsibility, and increased violations of professional boundaries. It was concluded that three trajectories can be distinguished with regards to the relationship between therapists’ motivation and the process and consequences of their empathy. It was recommended that institutions responsible for the recruitment, training and supervision of therapists should become aware of the role of therapist motivation in the counselling process, and reinvest in the importance of therapists’ emotional responsivity as conducive to therapy, and that future research into therapeutic correlates of motivation is required to support the tyme-share.
Encountering risk: 'everyday' experiences of outdoor adventure education instructors
Creators: name: Funnell, Aaron Brook
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: This thesis is a qualitative study of the lived experience of risk in outdoor adventure education and was guided by the following research question: How do outdoor adventure education instructors experience everyday risks and make decisions in their work? Existing research and professional literature on this topic is largely quantitative based and has tended to focus on accident trends and patterns. As such this study contributes to the current body of knowledge by expanding this topic through the use of qualitative methods. Specifically this thesis departs from the prevailing positivist and post-positivist approaches, and employs a phenomenological orientation to take a constructionist approach to risk in which the everyday experiences of outdoor adventure education (OAE) instructors are given a voice. The insights found in their stories enrich the current body of knowledge about risk and decisionmaking in OAE. A unique aspect of the study involved a critical review of a wide range of risk research and literature that was sourced from both inside and outside of OAE. This was done in an attempt to ascertain where common and taken-for-granted ideas, concepts and practices relating to risk in OAE have their origins and, in some cases, raised questions about their suitability for use in OAE. This critical review also prepared the researcher for the datagathering phase of the research. In the study phase of the research a series of three in depth 'phenomenological interviews' (Seidman, 1998) were completed with each of three participants who had an extensive employment history as instructors in OAE in Asia. These nine interviews in total resulted in a considerable amount of 'experiential data' (van Manen, 1990) which was coded, analysed and thematised to produce research texts (van Manen, 1990) about the phenomenon under investigation. An investigation into the lived experience of risk is enlightening as OAE instructors usually take a duel approach to risk. Risks to program participants are both managed for safety, but are also intentionally used as a form of pedagogy. As the research was conducted in Asia this thesis also contributes to the body of OAE knowledge from this region as it explores a phenomenon (OAE) which has both international and local dimensions. Four themes emerged from this study. The most significant of these is the use of folk models of risk and decision-making by OAE instructors when engaged in their daily practice. The other themes identified were the role of human subjectivity in the lived experience of risk; experience, risk and judgment; and, finally that of risk as a form of pedagogy.

description: Machine Learning Techniques (MLT) require large amounts of historical data needed for training the prediction models that is not always available. Since the Photovoltaic system behavior is nonlinear due to the unpredictable nature of the weather conditions throughout the year, MLT training require annual historical data to
create the prediction model. The Photovoltaic system production meters store up to 3 months of historical power values.
This information served as motivation to research different types of MLTs, in search of one that would accurately predict the daily solar AC energy values of a Photovoltaic system in any season of the year regardless of its location based on the available 3-month historical data used for training the prediction model. Therefore, five MLTs were compared which are the Regression Tree, Artificial Neural Network, Multi-Gene Genetic Programming, Gaussian
Process and the Support Vector Machine for Regression. Results show that the Multi-Gene Genetic Programming presented the best prediction values throughout the four seasons of the year regardless of the Photovoltaic system location by only using 3 months of historical data for training the prediction model.
Law enforcement at the border: a changing paradigm
Creators: name: Shallies, Bradley
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: The research presented in this paper is based essentially around three identified research questions: What is influencing the changing understanding of organised crime? How is organised crime represented in major Commonwealth Government committee reports and policy frameworks? How are cross-agency partnerships conceptualised and translated into the Australian government's responses and actions to organised crime in Australia? In addressing the theme of these questions, the research presents as separate components elements of the issues, all however interconnected to establish that there is a vastly changed understanding of organised crime. Within this understanding however remains a significant degree of complexity in regard to what is considered to be a viable and enduring definition of organised crime. This complexity is well illustrated in the literature synthesis. It is through the prism of changed and changing understanding that the law enforcement response to serious and organised crime is being designed and implemented. The contemporary understanding actually challenges the need or desirability for a structured definition to which everyone collectively subscribes. In fact it is more about an acceptance that there is an upper echelon of serious and organised criminality which has significant social and economic impacts and hence that the response, cognisant of that understanding, needs to change. Chapters Five, Six and Seven take the reader on a journey through the aspects that have shaped the contemporary Australian understanding and ultimately how that understanding has been applied through Task Force Polaris. This task force relates to, as does some of the preceding discussion, serious and organised crime back in the border domain, which is of heightened interest to the Commonwealth agencies. How the theory regarding partnership work as illustrated in Chapter Six is validated through the response modelling as illustrated in Chapter Seven is particularly interesting. The interviews conducted with law enforcement officials are woven through a number of the chapters where the responses best add value to the themes being examined. The responses clearly indicated an awareness of the changed understanding of serious and organised crime but a heightened awareness of the Government policy overlay and how that policy direction was being realised through the response.

description: In most of the realistic ab initio and model calculations which have appeared on the emission of light from Si nanocrystals, the role of surface oxygen has been usually ignored, underestimated or completely ruled out. We investigate theoretically, by density functional theory (DFT/B3LYP) possible modes of oxygen bonding in hydrogen terminated silicon quantum dots using as a representative case of the Si29 nanocrystal. We have considered Bridge-bonded oxygen (BBO), Doubly-bonded oxygen (DBO), hydroxyl (OH) and Mix of these oxidizing agents. Due to stoichiometry, all comparisons performed are unbiased with respect to composition whereas spatial distribution of oxygen species pointed out drastic change in electronic and cohesive characteristics of nanocrytals. From an overall perspective of this study, it is shown that bridge bonded oxygenated nanocrystals accompanied by Mix have higher binding energies and large electronic gap compared to nanocrystals with doubly bonded oxygen atoms. In addition, it is observed that the presence of OH along with BBO, DBO and mixed configurations further lowers electronic gaps and binding energies and trends. It is also demonstrated that oxidizing constituent besides their spatial distribution significantly alters binding energy and highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) gap (HOMO-LUMO gap up to 1.48 eV) within same composition.

description: The potential-induced degradation (PID) contributes to detrimental influence on the performance of crystalline silicon solar modules in the field photovoltaic power plant. PID decreases the energy conversion efficiency of solar modules significantly and hazards the reliability of photovoltaic system. This paper focuses on the
degradation and power loss resulting from PID in the PV power plant under comprehensive operating conditions. And important location distribution law of PID in strings and modules was revealed for the first time by using thermography and electroluminescence (EL) imaging. The degradation law of module’s output power and open circuit voltage (Voc) are presented by measuring current-voltage (I-V) and power-voltage (P-V) curves characteristic.
The energy conversion efficiency of PV system was reduced tremendously led by PID. The degradation of PV modules in maximum output power is as high as 53%. The yield loss of an array affected by PID is about 40%. High temperature and relative humidity have proved to aggravate PID. The results of this work are considered as a basement to further study the mechanism of PID and the effect of PID on energy conversion efficiency of PV system in the field.

description: Storage allocation affects important performance measures of distributed storage systems. Most previous studies on the storage allocation consider its effect separately either on the success of the data recovery or on the service rate (time) where it is assumed that no access failure happens in the system. In this paper, we go one step further and incorporate the access model and the success of data recovery into the service rate analysis. In particular, we focus on quasi-uniform storage allocation and provide a service rate analysis for both fixed-size and probabilistic access models at the nodes. Using this analysis, we then show that for the case of exponential waiting time distribution at individuals storage nodes, minimal spreading allocation results in the highest system service rate for both access models. This means that for a given storage budget, replication provides a better service rate than a coded storage solution.

description: Music pervades the lives of children. While we hear it in songs, advertising jingles and soundtracks aimed at children, rarely do we hear music composed by children. Through diminished opportunities in many schools and homes, children have been encouraged to be consumers but not producers of music. This not only limits children's relationship with music directly, but their socialisation, the development of identity and other aspects of education which may be accessed, enabled or understood through music. Advances in computer technology have revolutionised the music world, providing tools and creative music opportunities for children and adults alike. Using some of this technology, this case study observed how two sisters, aged three and five, wrote and recorded authentic musical stories in collaboration with the researcher-participant. Over two sessions, the girls participated in drawing, storytelling and discussion, ukulele, singing and recording through a laptop with Garageband. Video footage, audio of the songs, screen shots, graphs, diagrams, written reflections and photographs were analysed and discussed in relation to the themes explored in the literature review. These included: flow, creativity, self-efficacy, thought, agency, collaboration, imagination, technology and play. In order to integrate the audio, visual and written components of the study, the thesis is presented in a website. This study provides us with a glimpse into the remarkable possibilities offered by intergenerationally generated music. Through play, dialogue, creative tools, multi-modal processes and relationships, such music has the power to transform the lives of children and those with whom they collaborate, their families, education and culture. Through hearing these songs and observing the processes that led to their creation, we are invited to consider, or re-consider: "What is the role of music in the lives of children?".

description: Semiconductor materials that can be doped both n-type and p-type are desirable for diode-based applications and transistor technology. Copper nitride (Cu3N) is a metastable semiconductor with a solar-relevant bandgap that has been reported to exhibit bipolar doping behavior. However, deeper understanding and better control of the mechanism behind this behavior in Cu3N is currently lacking in the literature. In this work, we use combinatorial growth with a temperature gradient to demonstrate both conduction types of phase-pure, sputter-deposited Cu3N thin films. Room temperature Hall effect and Seebeck effect measurements show n-type Cu3N with 10^17 electrons/cm^3 for low growth temperature (~35 degrees C) and p-type with 10^15-10^16 holes/cm^3 for elevated growth temperatures (50-120 degrees C). Mobility for both types of Cu3N was ~0.1-1 cm^2/Vs. Additionally, temperature- dependent Hall effect measurements indicate that ionized defects are an important scattering mechanism in p-type films. By combining X-ray absorption spectroscopy and first-principles defect theory, we determined that V_Cu defects form preferentially in p-type Cu3N while Cu_i defects form preferentially in n-type Cu3N. Based on these theoretical and experimental results, we propose a kinetic defect formation mechanism for bipolar doping in Cu3N, that is also supported by positron annihilation experiments. Overall, the results of this work highlight the importance of kinetic processes in the defect physics of metastable materials, and provide a framework that can be applied when considering the properties of such materials in general.

description: In [Bianco, L., Giuseppe C., and P. Reverberi. 2001. "A network based model for traffic sensor location with implications on O/D matrix estimates". Transportation Science 35(1):50-60.], the authors present the Sensor Location Problem: that of locating the minimum number of traffic sensors at intersections of a road network such that the traffic flow on the entire network can be determined. They offer a necessary and sufficient condition on the set of monitored nodes in order for the flow everywhere to be determined. In this paper, we present a counterexample that demonstrates that the condition is not actually sufficient (though it is still necessary). We present a stronger necessary condition for flow calculability, and show that it is a sufficient condition in a large class of graphs in which a particular subgraph is a tree. Many typical road networks are included in this category, and we show how our condition can be used to inform traffic sensor placement.

description: This article presents a study aimed at understanding and analyzing the main forms of degradation that the PV modules of multicrystalline technology are subject to and their respective influence on the performance of electric power generation. For that, the forms of degradation found in the modules installed in the photovoltaic plant located in the premises of the Research Laboratory in Power Electronics of the Federal University of Uberlândia (NUPEP-FEELT-UFU) were identified and analyzed. Initially a visual inspection was performed and thermographic
images were obtained and evaluated in order to identify Hot Spots and to associate them with the signs of degradation observed. Additionally, the I-V and P-V curves were measured in loco to obtain the main parameters used to measure the performance quality of the photovoltaic modules. For the validation of the results found, these were compared with the data obtained through a computational model, taking into account the same operational conditions, i.e., cell operating temperature and incident irradiation in the plane of the modules.

description: In the history of education it has long been discussed that single-sex and coeducation are the two models of education present in schools. With the introduction of parallel schools over the last 15 years, there has been very little research into this 'new model'. Many people do not understand what it means for a school to be parallel or they confuse a parallel model with co-education, due to the presence of both boys and girls within the one institution. Therefore, the main objective of this research is to analyse the various parallel models in Australia and the USA as a means to decipher a definition of what parallel education is. This study reflects a qualitative paradigm, encompassing standardised openended interviews which allowed participants to discuss their perceptions and experiences with parallel secondary schools. The chosen participants are key people responsible for the development or running of such schools. As a case-study driven research, the intention was to investigate the different structures of parallel schools, why they were developed and how each of these structures function. As independent schools, each school researched is at liberty to develop its own structure of parallel education; however, the findings of this study suggest that there are two key features that define a parallel school and a third feature that is common to most of them. In defining a parallel school, the case-studies reveal that both a single-sex and co-educational classroom environment alternating throughout its structure, as well as a co-educational community, are key aspects of a parallel school. Another important feature although it does not appear to be as critical, is the presence of one overseeing administration and a separate girls and boys school. This study also suggests that the previous literature discussions of single-sex and co-educational advantages and disadvantages should now include parallel schools as a separate and third model. This is mainly as the research suggests this third model is able to provide both a single-sex and co-educational environment which appears to support the advantages of both single-sex and co-educational schools whilst diminishing the disadvantages.

description: For a completely regular space $X$, denote by $C_p(X)$ the space of continuous real-valued functions on $X$, with the pointwise convergence topology. In this article we strengthen a theorem of O. Okunev concerning preservation of some topological properties of $X$ under homeomorphisms of function spaces $C_p(X)$. From this result we conclude new theorems similar to results of R. Cauty and W. Marciszewski about preservation of certain dimension-type properties of spaces $X$ under continuous open surjections between function spaces $C_p(X)$.

description: Potential induced degradation (PID) causes severe damage and financial losses even in modern PVinstallations.
In Germany, approximately 19% of PV-installations suffer from PID and resulting power loss. This paper focuses on the impact of PID in real installations. The analysis focuses exemplarily on a 314 kWp PV-system in the Atlantic coastal climate. Infrared (IR)-imaging is used for identifying PID without operation interruption. Historic electric performance monitoring data for several years are analyzed on system and string level. Additionally, punctually measured module string current-voltage (I-V)-curves are considered. The data sets are combined for understanding the PID behavior of this PV plant. The number of PID affected cells within a string varies strongly between 1 to 22% with the string position
on the building complex. A PID-resistance which correlates to the defined PID-defect-ration is presented. Finally, indicators
for the reliable determination of PID is given.
