description: In this paper we introduce, for the first time, the Weibull-Geometric distribution which generalizes the exponential-geometric distribution proposed by Adamidis and Loukas (1998). The hazard function of the last distribution is monotone decreasing but the hazard function of the new distribution can take more general forms. Unlike the Weibull distribution, the proposed distribution is useful for modeling unimodal failure rates. We derive the cumulative distribution and hazard functions, the density of the order statistics and calculate expressions for its moments and for the moments of the order statistics. We give expressions for the Rényi and Shannon entropies. The maximum likelihood estimation procedure is discussed and an algorithm EM (Dempster et al., 1977; McLachlan and Krishnan, 1997) is provided for estimating the parameters. We obtain the information matrix and discuss inference. Applications to real data sets are given to show the flexibility and potentiality of the proposed distribution.

With the expansion in scale and complexity of the power grids, it is of great important to analyze and study the economics, reliability and security of power systems by mining massive amount of grid data. It is very challenging to generate knowledge from the heterogeneous big data set automatically to identify customer behavior, increase transmission line transfer capacity, identify system disturbance, perform online equipment diagnosis, assess system stability, and perform emergency controls. The deep learning and data mining algorithms have great potential in analyzing power system operating data and extracting useful operation rules. At last, it is critical to develop new big data applications in power systems. In this panel session, the advanced big data analytics algorithms and applications for power systems will be discussed.

description: Diamondoids and their derivatives have found major applications as templates and as molecular building blocks in nanotechnology. Applying ab initio method, we calculated the quantum conductance and the essential electronic properties of two lower diamondoids (adamantane and diamantane) and three of their important derivatives (amantadine, memantine and rimantadine). We also studies two artificial molecules that are built by substituting one hydrogen ion with one sodium ion in both adamantane and diamantane molecules. Most of our results are based on an infinite Au two-probe system constructed by ATK and VNL software, which comprise TRANSTA-C package. By changing various system structures and molecule orientations in linear Au and 2 by 2 Au probe systems, we found that although the conductance of adamantane and diamantane are very small, the derivatives of the lower diamondoids have considerable conductance at specific orientations and also showed interesting electronic properties. The quantum conductance of such molecules will change significantly by changing the orientations of the molecules, which approves that residues like nitrogen and sodium atoms have great effects on the conductance and electronic properties of single molecule. There are obvious peaks near Fermi energy in the transmission spectrums of artificial molecules, indicating the plateaus in I-V characteristics of such molecules.

Technical Session
With sharp increase in renewable generation connecting to the power grid, short circuit models of such generation used in commercial fault and protection analysis simulation programs, have come under scrutiny and need to be updated. The challenges hindering this effort is the unavailability of control data for the converters that interconnect such generation with the grid, lack of grid codes (with a few exceptions), and performance requirements for fault response of these devices. Working Group C24 in the Power System Relaying and Control Committee (PSRC) has been working to get consensus about the data that the wind turbine and PV system manufacturers can provide, without revealing proprietary details, that can be used to develop accurate short circuit models by developers of short circuit analysis tools. The presenters in this panel will discuss the need and development of such models. Validated generic models developed by EPRI and models incorporated in commercial short circuit programs will be showcased.

description: The near-Earth space weather is driven by the quick release of magnetic free energy in the solar corona. Probing this extremely hot and rarified region of the extended solar atmosphere requires modeling the polarization of forbidden and permitted coronal lines. To this end, it is important to develop efficient codes to calculate the Stokes profiles that emerge from given three-dimensional (3D) coronal models, and this should be done taking into account the symmetry breaking produced by the presence of magnetic fields and non-radial solar wind velocities. We have developed such a tool with the aim of theoretically predicting and interpreting spectropolarimetric observations of the solar corona in permitted and forbidden lines. In this paper we show the results of a theoretical investigation of the linear polarization signals produced by scattering processes in the H I Ly-$α$ line at 1216 A and in the He II Ly-$α$ line at 304 A using 3D coronal models by Predictive Science Inc. These spectral lines have very different critical magnetic fields for the onset of the Hanle effect (53 G and 850 G, respectively), as well as different sensitivities to the Doppler effect caused by the solar wind velocities. We study under which circumstances simultaneous observations of the scattering polarization in these Ly-$α$ lines can facilitate the determination of magnetic fields and macroscopic velocities in the solar corona.

2019 PES ISGT NA Panel Session

The electric industry landscape is undergoing fundamental changes due to a combination of factors, which include the proliferation of Distributed Energy Resources (DERs), new technologies, electrification of transportation, and the emergence of increasingly savvy prosumers (consumers with distributed generation sources such as rooftop solar and energy storage). In this emerging electricity landscape, prosumers are increasingly demanding the freedom to trade electric energy with other prosumers or the utility as they please based on price and other value preferences they may have. The volume, frequency, variety, and variability of these transactions call for new methods for tracking, bookkeeping, settlement, and dispute resolution associated with such transactions. Transactive Energy platforms and Blockchain technology can collectively address these issues if properly designed and deployed.

The initially conceived Blockchain technology has potential drawbacks in terms of processing efficiency and computational burden to be usable in this context. However, the emerging

Energy Blockchain methods are not hampered with these inefficiencies. This panel session will address the following topics:

The emerging electric industry landscape and peer-to-peer Transactive Energy Systems

Blockchain elements, attributes, and functions

Potential uses of Blockchain in Transactive Energy systems

2019 PES ISGT NA Panel Session
The Innovative Smart Grid Technologies (ISGT) Conference is celebrating 10 years of transformational changes in the electric power industry. In this last decade power delivery systems have evolved from passive, radial and relatively simple systems, into active and complex grids, where Distributed Energy Resources (DER), bidirectional power flows, renewable generation, and real-time monitoring, protection, automation and control are rapidly becoming the norm. Electric utilities have chosen a variety of approaches to pursue the objectives defined by the Smart Grid vision, to ensure that proposed solutions are customized to meet their own realities, requirements, and constraints, and the evolving needs of their customers. The investments made in this evolution toward the Utility and Grid of the Future have provided important benefits, and while significant progress has been made, important business, regulatory and technical challenges and needs remain in this new reality. For instance, how to successfully modernize the grid, integrate DERs and electric transportation, and provide a reliable, resilient and affordable service to end users in a world of declining or stagnated demands; how to solve evolving issues, such as cyber and physical security threats, and impacts of changing weather patterns, etc. This plenary session will review how our industry has changed in the last 10 years while transitioning towards the Smart Grid vision, and focus on discussing how electric utilities are preparing for addressing the challenges and needs of the Grid of the Future and potential transformational changes, like energy storage, transportation electrification, and distribution markets.

description: We theoretically investigate the magnetoelastic coupling (MEC) and its effect on magnon transport in two-dimensional antiferromagnets with a honeycomb lattice. MEC coeffcient along with magnetic exchange parameters and spring constants are computed for monolayers of transition metal trichalcogenides with Néel order ($\text{MnPS}_3$ and $\text{VPS}_3$) and zigzag order ($\text{CrSiTe}_3$, $\text{NiPS}_3$ and $\text{NiPSe}_3$) by $ab$ $initio$ calculations. Using these parameters, we predict that the spin-Nernst coefficient is significantly enhanced due to magnetoelastic coupling. Our study shows that although Dzyaloshinskii-Moriya interaction can produce spin Nernst effect in these materials, other mechanisms such as magnon-phonon coupling should be taken into account. We also demonstrate that the magnetic anisotropy is an important factor for control of magnon-phonon hybridization and enhancement of the Berry curvature and thus the spin-Nernst coefficient. Our results pave the way towards gate tunable spin current generation in 2D magnets by SNE via electric field modulation of MEC and anisotropy.

description: We examine the transport properties of a double quantum dot system coupled to a topological superconducting nanowire hosting Majorana quasiparticles at its ends, with the central quantum dot attached to the left and right leads. We focus on the behavior of the local density of states and the linear conductance, calculated with the aid of the numerical renormalization group method, to describe the influence of the Majorana coupling on the low-temperature transport properties induced by the Kondo correlations. In particular, we show that the presence of Majorana quasiparticles in the system affects both the spin-up and spin-down transport channels, affecting the energy scales associated with the first-stage and second-stage Kondo temperatures, respectively, and modifying the low-energy behavior of the system.

An investigation of the effects of age and stroke on implicit motor imagery as demonstrated by a hand laterality judgment test
Creators: name: Sapsford, Frances Jane
Publisher: name: Lancaster University
Year: 2020

description: Background Explicit motor imagery is recommended for stroke rehabilitation but can be difficult to practice. Hand Laterality Judgement (HLJ) stimulates implicit motor imagery which may be easier for stroke patients, but its benefits are unknown. Previous studies are inconclusive and have not considered the effects of older age. Objectives. This thesis investigated the effects of older age and stroke on HLJ and the effects of practising HLJ after a stroke. Methods Three experiments were undertaken. The first compared HLJ in twenty young, healthy participants (mean=22(2) years) with twenty aged 60 -70 years (mean=67(3) years) and twenty-two aged ≥ 70 years (mean=77(5) years). The second compared HLJ of eleven stroke survivors aged ≥ 60 years (mean =69 (6)) with age-matched controls. The third examined the effects of practising HLJ in four stroke survivors. Main findings There were no significant differences in HLJ response times between the young and older groups (p=.06) or between the stroke and control group (p=.13). Both older groups were significantly less accurate than the younger group (young group =92%; older groups= 81%-86% p≤ .00). There were no significant differences in accuracy between the two older groups (P=.10) or between the stroke and control groups (p=.59). All groups engaged in implicit motor imagery, but this was impaired by early old age. Visuospatial imagery was impaired in later old age and by stroke. There were no significant relationships between HLJ performance and upper limb impairment post-stroke. There were no significant effects of practising HLJ, but trends towards increased accuracy (d=.24) and slower response times (d=.46). Conclusion. Stroke survivors can perform HLJ as well as similarly aged healthy individuals. Stroke may impair visuospatial imagery, but accuracy improves with practice. Further research is needed to determine if there are any benefits to post-stroke upper limb rehabilitation.
Comparison of procedures for testing the equality of survival distributions
Creators: name: Joe, Harry
Publisher: name: University of British Columbia
Year: 2010

description: A common problem in life testing is assessing whether two survival distributions are identical. Sequential procedures based on the Mantel-Haenszel statistic (Muenz, Green and Byar, 1977), the Wilcoxon statistic (Davis, 1978) and the Savage statistic (Koziol and Petkau, 1978) have been proposed for testing the equality of two survival distributions. These procedures, and their fixed point censoring counterparts, are numerically compared on the basis of power under Lehmann alternatives and expected proportion sampled. Among the sequential procedures, those based on the Wilcoxon and Savage statistics seem preferable to that based on the Mantel-Haenszel statistic. Early decision rules are introduced and shown to be of value if used in conjunction with either the sequential or fixed point censoring procedures. Finite sample corrections to the asymptotic critical values of the sequential procedure proposed by Koziol and Petkau are presented.

description: We present new Spitzer Space Telescope observations of stars in the young ~5 Myr gamma Velorum stellar cluster. Combining optical and 2MASS photometry, we have selected 579 stars as candidate members of the cluster. With the addition of the Spitzer mid-infrared data, we have identified 5 debris disks around A-type stars, and 5-6 debris disks around solar-type stars, indicating that the strong radiation field in the cluster does not completely suppress the production of planetesimals in the disks of cluster members. However, we find some evidence that the frequency of circumstellar primordial disks is lower, and the IR flux excesses are smaller than for disks around stellar populations with similar ages. This could be evidence for a relatively fast dissipation of circumstellar dust by the strong radiation field from the highest mass star(s) in the cluster. Another possibility is that gamma Velorum stellar cluster is slightly older than reported ages and the the low frequency of primordial disks reflects the fast disk dissipation observed at ~5 Myr.

description: We report on the observation of terahertz radiation induced edge photogalvanic currents in graphene, which are nonlinear in intensity. The increase of the radiation intensities up to MW/cm$^2$ results in a complex nonlinear intensity dependence of the photocurrent. The nonlinearity is controlled by the back gate voltage, temperature and radiation frequency. A microscopic theory of the nonlinear edge photocurrent is developed. Comparison of the experimental data and theory demonstrates that the nonlinearity of the photocurrent is caused by the interplay of two mechanisms, i.e. by direct inter-band optical transitions and Drude-like absorption. Both photocurrents saturate at high intensities, but have different intensity dependencies and saturation intensities. The total photocurrent shows a complex sign-alternating intensity dependence. The functional behaviour of the saturation intensities and amplitudes of both kinds of photogalvanic currents depending on gate voltages, temperature, radiation frequency and polarization is in a good agreement with the developed theory.

description: Preparing the ground state of a system of interacting classical particles is an NP-hard problem. Thus, there is in general no better algorithm to solve this problem than exhaustively going through all N configurations of the system to determine the one with lowest energy, requiring a running time proportional to N. A quantum computer, if it could be built, could solve this problem in time sqrt(N). Here, we present a powerful extension of this result to the case of interacting quantum particles, demonstrating that a quantum computer can prepare the ground state of a quantum system as efficiently as it does for classical systems.

Late Breaking News - Managing Today�s Grid for Reliability, Resiliency and Sustainability

Technological Advancements to Manage Modern Electrical Grids

The requirements for the electric power grid are evolving with customer expectations, challenges stemming from climate changes, and transition to renewable and distributed forms of generation. New and emerging technology can help to respond to these evolving requirements, while maintaining and improving the reliability and resiliency of the grid. For example, higher penetration of DER is requiring visibility and dynamic control at levels not seen before.

This panel seeks to understand how electric utilities and technology providers are proposing new technologies and implement initiatives to the evolving grid. The panelist will discuss on a number of advanced technologies to increase observability and controllability of the system, including digital sensors, synchrophasors, communications and data management tools. Along with specific focus on software tools such as Advanced Distribution Management System, Distributed Energy Resource Management System, Microgrid Controls, and State Estimation.

The panelists will also discuss how to manage risk and cost in deploying advanced technology; and how each of them is approaching the challenges and opportunities on grid management both through technical and non-technical paths

description: The aim of this study is to design and evaluate a simple free running Analog-Digital Converter (ADC) based on the Field Programmable Gate Array (FPGA) device to accomplish the energy and position readout of the silicon photomultiplier (SiPM) array for application as PET scanners. This simple FPGA-ADC based on a carry chain Time-Digital Converter (TDC) implemented on a Kintex-7 FPGA consists of only one off-chip resistor so it has greater advantages in improving system integration and reducing cost than commercial chips. In this paper, a FPGA-ADC based front-end electronics prototype is presented, and both the design principle and implementation considerations are discussed. Experiments were performed using an 8 x 8 (crystal size: 4 x 4 x 15 mm3 ) and a 12 x 12 (crystal size: 2.65 x2.65 x 15 mm3 ) segmented LYSO crystals coupled with an 8 x 8 SiPM (Jseries, from ON Semiconductor) array which is under 22Na point source excitation. Initial test results indicate that the energy resolution of the two detectors after correction is around 13.2% and 13.5 % at 511 keV, and the profiles of the flood histograms show a clear visualization of the discrete scintillator element. All measurements were carried out at room temperature (~25 degree), without additional cooling

Technical Session
This panel discusses new approaches that the apply Modern Heuristics to Robust Optimization (RO) in power system operation and planning. In recent years, the emergence of renewable energy has brought about uncertainties to power systems. Simple stochastic programming is popular as an optimization method with uncertain variables, but it is time-consuming because of setting up the additional conditions to the formulations. To overcome that, Alternative methods are required to deal with optimization problems with uncertain variables. RO focuses on the optimal solution in the worst case from a standpoint of risk minimization. This panel introduces Modern Heuristics (MH) into the RO problems to overcome a drawback of RO to fail to solve non-convex problems. It is expected that the use of MH allows decision makers to set up a strategy to the worst case in power systems.

2019 IEEE General Meeting Panel Presentation: Ensuring Grid Resilience through Policy, Standards and Market Constructs
The modern bulk electricity grid is a complex cyber-physical system, not only does it contain traditional generation, transmission and distribution systems, but also IT, communication and control systems.
In addition, the reliable operation of the grid relies on other external infrastructures, such as transportation and gas pipeline networks, etc. Failures in any of these systems during extreme weather events or human attacks could lead to a system blackout, resulting in significant loss of the economy. Grid resilience, often described as the ability to harden the system against - and quickly recover from - high-impact low-frequency (HILF) events, therefore becomes an important issue in the power industry, and is getting more and more attention from stakeholders as well as policy makers such as DOE, FERC and State Commissions. For instance, FERC has requested each ISO/RTO region to provide comments on the definition, metrics and mitigation measures of grid resilience. The meaning of grid resilience could be different depending on the geographic location of the grid, its regulatory framework, and the characteristics of regional resource mix. The definition and metrics associated are highly linked with those of power system reliability. Grid resilience challenges can be addressed by regulatory policies, enhanced operating and planning procedures, or market constructs. Improving grid resilience can create wide-spread impact on ISO/RTO, transmission, distribution and generation companies as well as consumers. This session will focus its discussion on the definition, metrics, and market solutions to grid resilience as well as its impact on stakeholders. Panelists will discuss the current status and potential enhancements to operating procedures, planning procedures, and incentives to ensure that resources are able to supply and deliver energy, and recover the system sufficiently, during various HILF events.
Effects of Diffusion on Photocurrent Generation in Single-Walled Carbon Nanotube Films

description: We have studied photocurrent generation in large carbon nanotube (CNT) films using electrodes with different spacings. We observe that the photocurrent depends strongly on the position of illumination, with maximum observed response occurring upon illumination at the electrode edges. The rate of change of the response decays exponentially, with the fastest response occurring for samples with the smallest electrode spacing. We show that the time response is due to charge carrier diffusion in low-mobility CNT films.

Publisher: name: IEEE
Year: 2019

Technical Session
The automation of the electric distribution line device is a fundamental building block for the Smart Grid. Like the construction of Rome, the automation of the distribution system has been a gradual process. However, the successful automation efforts will achieve the goal of full automation with a strategy and a timeline that is consistently and steadily expanding the automation to the distribution line devices. This panel session will explore the utility perspective for automating the electric distribution system. Line sensing auxiliary devices will be discussed for collecting distribution line telemetry for analog and status measurements. The planning perspective will be discussed for the expansion of automation throughout the distribution system. An integration strategy will be presented to achieve automation throughout the electric distribution system.
High energy scattering in the saturation regime including running coupling and rare fluctuation effects

Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The analytic result for the $S$-matrix in the saturation regime including the running coupling is obtained. To get this result we solve the Balitsky and Kovchegov-Weigert evolution equations in the saturation regime, which include running coupling corrections. We study also the effect of rare fluctuations on top of the running coupling. We find that the rare fluctuations are less important in the running coupling case as compared to the fixed coupling case.

Focus on reliable power delivery has intensified over the last two decades. More and more customers expect that their power will be on all the time. Events on the distribution system account for the vast majority of all interruption events (depending on which measure used it is calculated at over 95% of all interruption events; on some systems, the distribution system is the source of close to 99% of all events). In order to analyze interruption data preparatory to scoping any necessary improvements, the interruption event records need to be accurate. This panel will look at different utilities practices and techniques of reviewing their interruption events to ensure the accuracy of the interruption data. Besides investor owned utilities, cooperative power providers, rural electric providers and municipal providers will be represented.

2018 PES T&D Panel Presentation
The increasing complexity of the electric power network and its management, growing demand and service quality expectations such as greater grid reliability, efficiency and security, as well as environmental and energy sustainability concerns have triggered the next major step in the evolution of the electric power system towards a flexible power network or "Smart Grid". To achieve this result requires the implementation of new technologies in power systems, including renewable energy sources (RES), distributed generation (DG) and the latest information and communication technologies. Power quality is an important aspect of the power system which cannot be neglected and adequate power quality guarantees the necessary compatibility between consumer equipment and the grid. This panel will include five presentations which conclude the activities of the CIGRE/CIRED Working Group C4.24 on these topics.
A slitless spectroscopic survey for quasars near quasars

description: We present the results of the Quasars near Quasars (QNQ) survey, a CCD-based slitless spectroscopic survey for faint V<22 quasars at 1.71.7 we were able to confirm 80 new quasars at 0.5801.7. The overall high success rate implies that most of the remaining 88 candidates are quasars as well, although the majority of them likely resides at z<1.7 on the basis of the observed line shapes and strengths. Due to the insufficient depth of the input source catalogues needed for extraction of the slitless spectra our survey is not well defined in terms of limiting magnitude for faint 2.5

2019 PES ISGT NA Panel Session
Unfortunately, valuation of the grid services provided by energy storage is often a very difficult task. Different approaches must be employed for market areas versus a vertically integrated utility. For behind the meter applications, the utility rate structure often defines the value of energy storage that can be monetized. In many cases, the entity that accrues the grid benefits of energy storage is not the owner of the energy storage system, further complicating valuation. Because of these factors, the value of an energy storage system is often highly location dependent. The goal of this panel session is to review energy storage applications and the current state of the art in energy storage valuation techniques.
The interaction between xanthate and sulphur dioxide in the flotation of nickel-copper sulphide ores
Creators: name: Peres, Antonio Eduardo Clark
Publisher: name: University of British Columbia
Year: 2010

description: Electrochemical methods and small scale flotation tests were used to study the effects of sulphur dioxide and potassium amyl xanthate on the floatabilities of pentlandite, chalcopyrite and nickeliferous pyrrhotite, at pH 5.5. Mixed potentials of all three mineral systems were positive to the dixanthogen/xanthate redox couple, even in the presence of aqueous SO₂. Thus the existence of dixanthogen is thermodynamically favoured in all these systems. The tests also indicated that adsorption of xanthate by: (i) chalcopyrite is enhanced by SO₂; (ii) pentlandite is impaired by SO₂; (iii) pyrrhotite is unaffected by SO₂; Anodic polarization curves, determined on mineral electrodes, suggested that, in xanthated systems, the collector (probably dixanthogen) forms a film on the electrodes. This film inhibits the continued electron transfer reactions on the surface. The protective character of the film is higher for chalcopyrite (increased by SO₂), than for pentlandite (decreased by SO₂), than for pyrrhotite (unaffected by SO₂). Cathodic polarization curves indicated that the cathodic process, on pentlandite and pyrrhotite electrodes, is controlled by oxygen reduction. The reduction of oxidized species on the surface is suggested as the controlling mechanism on chalcopyrite electrodes. Small scale flotation tests showed that the presence of SO₂ increases an already very high,recovery of chalcopyrite; decreases a high recovery of pentlandite, and decreases further a very low recovery of pyrrhotite.

description: Quiescent filaments are usually affected by internal and/or external perturbations triggering oscillations of different kinds. In particular, external large-scale coronal waves can perturb remote quiescent filaments leading to large-amplitude oscillations. Observational reports have indicated that the activation time of oscillations coincides with the passage of a large-scale coronal wavefront through the filament, although the disturbing wave is not always easily detected. Aiming to contribute to understand how -- and to what extent -- coronal waves are able to excite filament oscillations, here we modelled with 2.5 MHD simulations a filament floating in a gravitationally stratified corona disturbed by a coronal shock wave. This simplified scenario results in a two-coupled oscillation pattern of the filament which is damped in a few cycles, enabling a detailed analysis. A parametric study was accomplished varying parameters of the scenario such as height, size and mass of the filament. An oscillatory analysis reveals a general tendency where periods of oscillations, amplitudes and damping times increase with height, whereas filaments of larger radius exhibit shorter periods and smaller amplitudes. The calculation of forces exerted on the filament shows that the main restoring force is the magnetic tension.
