Market performance and bidding behaviors in deregulated electricity market
Creators: name: Liao, Zhigang
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: The objective of this research is to investigate the impact of different pricing rules on the economic performance of a deregulated electricity market. In particular, the influence on the bid prices and profits of generators, total dispatch cost, and the volatility of these values will be examined. Given the debate, over the past two decades, regarding the selection of the best pricing rules, the applicability of the Revenue Equivalence Theorem in the deregulated electricity market is revisited in this research. This theorem has been adopted in the literature as a theoretical support for deciding pricing rule in the market settlement process. In this research, it is hypothesized that the Revenue Equivalence Theorem may not hold. Therefore, it is appropriate to analyze market performance when different pricing rules are imposed to govern the market. Furthermore, this research also highlights the importance of generators bidding strategies in the competitive electricity market. The different methods used to design generators bidding strategies as presented in the literature have been reviewed. In order to investigate the different impact of pricing rules on market performance, this research employs a computer simulation method. A simulation platform is used to imitate the business activities in the electricity auction market, mainly in relation to the bidding, scheduling and dispatching processes. An agent-based approach is adopted for this purpose. The competing generators in the electricity market are modeled as agents. Bid stacking is used to model the optimization process of the Independent System Operator. The generator agents bidding strategies are designed using the Q-Learning algorithm. A Q-Learning-driven generator agent enables it to actively learn from the historical and market information leading to more realistic and practical results. Different pricing rules under both maximum quantity bidding and variable quantity bidding are studied separately. The influence on the bid prices and profits of generators, total dispatch cost, and the volatility of these values are analyzed accordingly.

description: We study the construction of subgrid-scale models for large-eddy simulation of incompressible turbulent flows. In particular, we aim to consolidate a systematic approach of constructing subgrid-scale models, based on the idea that it is desirable that subgrid-scale models are consistent with the mathematical and physical properties of the Navier-Stokes equations and the turbulent stresses. To that end, we first discuss in detail the symmetries of the Navier-Stokes equations, and the near-wall scaling behavior, realizability and dissipation properties of the turbulent stresses. We furthermore summarize the requirements that subgrid-scale models have to satisfy in order to preserve these important mathematical and physical properties. In this fashion, a framework of model constraints arises that we apply to analyze the behavior of a number of existing subgrid-scale models that are based on the local velocity gradient. We show that these subgrid-scale models do not satisfy all the desired properties, after which we explain that this is partly due to incompatibilities between model constraints and limitations of velocity-gradient-based subgrid-scale models. However, we also reason that the current framework shows that there is room for improvement in the properties and, hence, the behavior of existing subgrid-scale models. We furthermore show how compatible model constraints can be combined to construct new subgrid-scale models that have desirable properties built into them. We provide a few examples of such new models, of which a new model of eddy viscosity type, that is based on the vortex stretching magnitude, is successfully tested in large-eddy simulations of decaying homogeneous isotropic turbulence and turbulent plane-channel flow.

description: We present new results on gravitational lensing over a cosmological Robertson-Walker backgrounds which extend and generalize previous works. Our expressions show the presence of new terms and factors which have been neglected in the literature on the subject. The new equations derived here for the optcal scalars allow to deal with more general matter content including sources with non Newtonian components of the energy-momentum tensor and arbitrary motion. Our treatment is within the framework of weak gravitational lenses in which first order effects of the curvature are considered. We have been able to make all calculations without referring to the concept of deviation angle. This in turn, makes the presentation shorter but also allows for the consideration of global effects on the Robertson-Walker background that have been neglected in the literature. We also discuss two intensity magnification, that we define in this article; one coming from a natural geometrical contruction in terms of the affine distance, that here we call $\tildeμ$, and the other adapted to cosmological discussions in terms of the redshift, that we call $μ'$. We show that the natural intensity magnification $\tildeμ$ coincides with the standard solid angle magnification ($μ$).

description: Turbulence is a paradigm for far-from-equilibrium systems without time reversal symmetry. To capture the nonequilibrium irreversible nature of turbulence and investigate its implications, we develop a potential landscape and flux field theory for turbulent flow and more general nonequilibrium fluid systems governed by stochastic Navier-Stokes equations. We find that equilibrium fluid systems with time reversibility are characterized by a detailed balance constraint that quantifies the detailed balance condition. In nonequilibrium fluid systems with nonequilibrium steady states, detailed balance breaking leads directly to a pair of interconnected consequences, namely, the non-Gaussian potential landscape and the irreversible probability flux, forming a 'nonequilibrium trinity'. The nonequilibrium trinity characterizes the nonequilibrium irreversible essence of fluid systems with intrinsic time irreversibility and is manifested in various aspects of these systems. The nonequilibrium stochastic dynamics of fluid systems including turbulence with detailed balance breaking is shown to be driven by both the non-Gaussian potential landscape gradient and the irreversible probability flux, together with the reversible convective force and the stochastic stirring force. We reveal an underlying connection of the energy flux essential for turbulence energy cascade to the irreversible probability flux and the non-Gaussian potential landscape generated by detailed balance breaking. Using the energy flux as a center of connection, we demonstrate that the four-fifths law in fully developed turbulence is a consequence and reflection of the nonequilibrium trinity. We also show how the nonequilibrium trinity can affect the scaling laws in turbulence.

Vortex formation and dynamics of defects in shells of active nematics

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We present a hydrodynamic model for a thin spherical shell of active nematic liquid crystal with an arbitrary configuration of defects. The active flows generated by defects in the director lead to the formation of stable vortices, analogous to those seen in confined systems in flat geometries, which generate an effective dynamics for four +1/2 defects that reproduces the tetrahedral to planar oscillations observed in experiments. As the activity is increased and the vortices become stronger, the defects are drawn more tightly into pairs, rotating about antipodal points. We extend this situation to also describe the dynamics of other configurations of defects. For example, two +1 defects are found to attract or repel according to the local geometric character of the director field around them, while additional pairs of opposite charge defects can give rise to flow states containing more than two vortices. Finally, we describe the generic relationship between defects in the orientation and singular points of the flow, and suggest implications for the three-dimensional nature of the flow and deformation in the shape of the shell.

description: We present a theoretical study to investigate sub- and super-luminal light propagation in a rubidium atomic system consisting of a Rydberg state by using density matrix formalism. The analysis is performed in a 4-level vee+ladder system interacting with a weak probe, and strong control and switching fields. The dispersion and absorption profiles are shown for stationary atoms as well as for moving atoms by carrying out Doppler averaging at room temperature. We also present the group index variation with control Rabi frequency and observe that a transparent medium can be switched from sub- to super-luminal propagation in the presence of switching field. Finally, the transient response of the medium is discussed, which shows that the considered 4-level scheme has potential applications in absorptive optical switching.

description: Similia Similibus Curantur is also called the law of similars. That is, when a drug produces pathological/pathogenic symptoms in healthy individual means, the same drug can relieve similar kinds of symptoms in individuals with the disease. The biological, pharmacological and toxicological action of capsaicin alkaloids is a perfect example to explain the Similia Similibus Curantur principle. Most of the drugs in homoeopathic materia medica contain toxicological, pharmacological, drug-proving, and traditional use-related symptoms and indications. Abnormal sensations and symptoms of the disease are caused by the involvement of a specific receptor or molecular pathway and gene functions. These receptors or molecules may be stimulated or suppressed by environmental, natural or artificial agents. In such conditions, the administration of specific homoeopathic medicine having a similar kind of affinity towards the particular receptors or molecules involved in the disease process leads to modulation of such receptor or molecular pathways (e.g., desensitization, sensitization, inhibition). These kinds of actions cause the betterment of symptoms or curative effects. So “Similia similibus curantur” can be understood as a similar receptor or molecular pathway involved in both drug molecules biological/ pharmacological and toxicological action and disease pathogenesis". The selection of medicine is by comparing the similarity between the receptor or molecular pathway in disease pathogenesis and drug pathogenesis. To avoid unwanted aggravations or side effects while using mother tinctures or solutions, administer them less than their physiological dose. The theory of the pharmacological basis of Similia Similia Curantur creates a rational method to apply this Similia Principle. Based on this theory, there is a possibility of discovering Novel drugs in the future that acts and gives a cure in similia similibus curantur way.
Design of Synchronous Section-Carry Based Carry Lookahead Adders with Improved Figure of Merit

description: The section-carry based carry lookahead adder (SCBCLA) architecture was proposed as an efficient alternative to the conventional carry lookahead adder (CCLA) architecture for the physical implementation of computer arithmetic. In previous related works, self-timed SCBCLA architectures and synchronous SCBCLA architectures were realized using standard cells and FPGAs. In this work, we deal with improved realizations of synchronous SCBCLA architectures designed in a semi-custom fashion using standard cells. The improvement is quantified in terms of a figure of merit (FOM), where the FOM is defined as the inverse product of power, delay and area. Since power, delay and area of digital designs are desirable to be minimized, the FOM is desirable to be maximized. Starting from an efficient conventional carry lookahead generator, we show how an optimized section-carry based carry lookahead generator is realized. In comparison with our recent work dealing with standard cells based implementation of SCBCLAs to perform 32-bit addition of two binary operands, we show in this work that with improved section-carry based carry lookahead generators, the resulting SCBCLAs exhibit significant improvements in FOM. Compared to the earlier optimized hybrid SCBCLA, the proposed optimized hybrid SCBCLA improves the FOM by 88.3%. Even the optimized hybrid CCLA features improvement in FOM by 77.3% over the earlier optimized hybrid CCLA. However, the proposed optimized hybrid SCBCLA is still the winner and has a better FOM than the currently optimized hybrid CCLA by 15.3%. All the CCLAs and SCBCLAs are implemented to realize 32-bit dual-operand binary addition using a 32/28nm CMOS process.

description: Angiogenesis plays important roles in physiological and pathologic conditions, but the mechanisms underlying this complex process often remain to be elucidated. In recently years, liquid-liquid phase separation (LLPS) has emerged as a new concept to explain many cellular functions and diseases. However, whether LLPS is involved in angiogenesis have not been studied until now. Here, we investigated the potential role of LLPS in angiogenesis and endothelial function. We found 1,6-hexanediol (1,6-HD), an inhibitor of LLPS, but not 2,5-hexanediol (2,5-HD) dramatically decreases neovascularization of Matrigel plug and angiogenesis response of murine corneal in vivo. Moreover, 1,6-HD but not 2,5-HD inhibits microvessel outgrowth of aortic ring and endothelial network formation. The endothelial function of migration, proliferation and cell growth are suppressed by 1,6-HD. Global transcriptional analysis by RNA-sequencing reveals that 1,6-HD specifically blocks cell cycle and down-regulates cell cycle-related genes including cyclin A1. Further experimental data show that 1,6-HD treatment greatly reduces the expression of cyclin A1 but with minimal effect on cyclin D1, cyclin E1, CDK2 and CDK4. The inhibitory effect of 1,6-HD on cyclin A1 is mainly through transcriptional regulation because proteasome inhibitors fails to rescue its expression. Furthermore, overexpression of cyclin A1 in HUVECs largely rescues the dysregulated tube formation upon 1,6-HD treatment. Our data reveal a critical role of LLPS inhibitor 1,6-HD in angiogenesis and endothelial function, which specifically affects endothelial G1/S transition through transcriptional suppression of CCNA1, implying LLPS as a possible novel player to modulate angiogenesis, and thus it might represent an interesting therapeutic target to be investigated in clinic angiogenesis-related diseases in future.

description: We analyze the surface energy and boundary layers for a chain of atoms at low temperature for an interaction potential of Lennard–Jones type. The pressure (stress) is assumed to be small but positive and bounded away from zero, while the temperature β−1 goes to zero. Our main results are: (1) As β→∞ at fixed positive pressure p>0, the Gibbs measures μβ and νβ for infinite chains and semi-infinite chains satisfy path large deviations principles. The rate functions are bulk and surface energy functionals E¯¯¯bulk and E¯¯¯surf. The minimizer of the surface functional corresponds to zero temperature boundary layers; (2) The surface correction to the Gibbs free energy converges to the zero temperature surface energy, characterized with the help of the minimum of E¯¯¯surf; (3) The bulk Gibbs measure and Gibbs free energy can be approximated by their Gaussian counterparts; (4) Bounds on the decay of correlations are provided, some of them uniform in β.

description: Strong constraints on the coupling of new light particles to the Standard Model (SM) arise from their production in the hot cores of stars, and the effects of this on stellar cooling. For new light particles which have an effective in-medium mixing with the photon, plasma effects can result in parametrically different production rates to those obtained from a naive calculation. Taking these previously-neglected contributions into account, we make updated estimates for the stellar cooling bounds on light scalars and vectors with a variety of SM couplings. In particular, we improve the bounds on light (m

description: We report a method to convert discrete representations of molecules to and from a multidimensional continuous representation. This model allows us to generate new molecules for efficient exploration and optimization through open-ended spaces of chemical compounds. A deep neural network was trained on hundreds of thousands of existing chemical structures to construct three coupled functions: an encoder, a decoder and a predictor. The encoder converts the discrete representation of a molecule into a real-valued continuous vector, and the decoder converts these continuous vectors back to discrete molecular representations. The predictor estimates chemical properties from the latent continuous vector representation of the molecule. Continuous representations allow us to automatically generate novel chemical structures by performing simple operations in the latent space, such as decoding random vectors, perturbing known chemical structures, or interpolating between molecules. Continuous representations also allow the use of powerful gradient-based optimization to efficiently guide the search for optimized functional compounds. We demonstrate our method in the domain of drug-like molecules and also in the set of molecules with fewer that nine heavy atoms.

Désinfection des surfaces

description: Dans les hôpitaux, la chambre des patients et de nombreuses surfaces doivent être nettoyées et désinfectées quotidiennement, et plus encore au départ du patient ou entre deux interventions. Classiquement les agents des services hospitaliers chargés de cette tâche utilisent des produits chimiques qu’ils appliquent à l’aide de chiffonnettes. Plusieurs auteurs s’accordent à dire que le résultat final n’est pas à la hauteur des exigences de l’hygiène hospitalière et de la prévention des transmissions croisées. Le facteur humain, la qualité des produits, le biofilm organisé… réduisent l’efficacité de cette procédure manuelle utilisant des produits chimiques. Nous avons testé l’efficacité désinfectante de l’exposition des surfaces aux rayonnements ultraviolets de courte longueur d’onde (UV-C) par des prélèvements bactériologiques sur les surfaces réalisés avant et après un nettoyage (détergent) suivi d’une irradiation aux UV-C, comparativement à un nettoyage par détergent-désinfectant à base d’ammonium quaternaire, ou à un nettoyage suivi d’une brumisation d’un mélange de peroxyde d’hydrogène et d’acide peracétique (désinfection automatique des surfaces par voie aérienne [DSVA]). Alors que le bionettoyage manuel apporte une réduction d’1 log de la charge bactérienne des surfaces (réduction de 90%), les UV-C sont 10 fois plus efficaces après 3 minutes d’exposition (réduction de 99% de la contamination), soit une désinfection voisine de celle apportée par la DSVA (2,25 logs). Cette désinfection automatisée très rapide pourrait être utilisée systématiquement après nettoyage des chambres pour toutes les situations cliniques y compris celles nécessitant la prescription de précautions complémentaires.

description: Background: With the rapid population ageing that is occurring world-wide, there is increasing interest in "smart home" technologies that can assist older adults to continue living at home with safety independence. This systematic review and critical evaluation of the world wide literature assesses the effectiveness and feasibility of smart-home technologies for promoting independence, health, well-being and quality of life, in older adults. Methods: A total of 1877 “smart home” publications were identified by the initial search of peer reviewed journals. Of these, 21 met our inclusion criteria for the review and were subject to data extraction and quality assessment. Results: Smart-home technologies included different types of active and passive sensors, monitoring devices, robotics and environmental control systems. One study assessed effectiveness of a smart home technology. Sixteen reported on the feasibility of smart-home technology and four were observational studies. Conclusion: Older adults were reported to readily accept smart-home technologies, especially if they benefited physical activity, independence and function and if privacy concerns were addressed. Given the modest number of objective analyses, there is a need for further scientific analysis of a range of smart home technologies to promote community living.

description: The CHErenkov / Scintillation Separation experiment (CHESS) has been used to demonstrate the separation of Cherenkov and scintillation light in both linear alkylbenzene (LAB) and LAB with 2g/L of PPO as a fluor (LAB/PPO). This is the first such demonstration for the more challenging LAB/PPO cocktail and improves on previous results for LAB. A time resolution of 338 +/- 12 ps FWHM results in an efficiency for identifying Cherenkov photons in LAB/PPO of 70 +/- 3% and 63 +/- 8% for time- and charge-based separation, respectively, with scintillation contamination of 36 +/- 5% and 38 +/- 4%. LAB/PPO data is consistent with a rise time of 0.75 +/- 0.25 ns.

description: The present report describes architecture and design of the low-frequency, multi-mode, radar to be installed on board of light UAV, envisaged for FLY-RADAR project.
 The radar system will have two operative modes, working as side-looking SAR and nadir-looking sounder, with two central frequencies in the P-band and VHF band respectively.
 In SAR mode, the radar will allow acquisition of full polarised (HH, HV, VH and VV) images, while in sounder mode only one polarisation will be used for producing radargrams.

description: Introduction Non-ischaemic dilated cardiomyopathy (DCM) is defined as dilatation and systolic impairment of the left ventricle in the absence of significant epicardial coronary artery disease or abnormal loading conditions. DCM is common condition with a prevalence of 1 in 250 and has substantial mortality through sudden cardiac death and pump failure. Current risk prediction models are suboptimal, and further work is required to find predictors of adverse outcome. Global longitudinal strain (GLS) has had conflicting results as to whether it determines prognosis in DCM and further work is needed to clarify this. Myocardial blood flow (MBF) has been found to be abnormal in DCM in a previous study using cardiovascular magnetic resonance (CMR), but has not been established with the novel Kellman quantitative perfusion technique. Furthermore, the determinants of impaired MBF in DCM are not well described. Although exercise capacity is reduced in DCM, the determinants of this are unclear. MBF has been found to be an important predictor of exercise capacity in other cardiac conditions. Methods Firstly, a systematic review was undertaken of several established databases of medical literature to determine whether GLS was predictive of prognosis in DCM. Subsequently, 37 patients with DCM were prospectively recruited into the main study. These patients underwent cardiopulmonary exercise testing and comprehensive CMR imaging with GLS assessment and quantitative myocardial perfusion. Results Our systematic review yielded 8 studies: 4 studies had an association between GLS and clinical outcomes in DCM and 4 studies did not. The larger higher quality studies tended to favour an association between abnormal GLS and clinical outcomes. In the prospective study, DCM patients had reduced myocardial perfusion reserve (MPR) compared to healthy controls (1.97±0.65 vs 3.08±0.79, respectively; p<0.001). MPR was a significantly correlated with % predicted peak VO2 (r=0.385; p=0.019). This remained significant when assessed in all multivariable models. MPR did not correlate with CMR markers of fibrosis. Conclusions The systematic review provides evidence to support GLS as a predictor of prognosis in DCM. However further larger prospective studies are required. MPR is reduced in patients with DCM when compared to controls. MPR is a significant predictor of percentage predicted peak VO2 in patients with DCM. CMR markers of fibrosis do not appear to contribute to reduced MPR in patients with DCM.

description: The growth of e-commerce has shifted to online social network websites in the last six years. Benefiting from the advantages of the interactive information technology infrastructure in online social network, social commerce is regarded as a new category of e-commerce. Many e-retailers have extended their businesses onto the social network (via social commerce) in the belief that social commerce will in time become the dominant mode of commerce. One key challenge in establishing social commerce as a dominant mode of commerce in the online context is the ability to build and maintain trust between consumers and businesses. The purpose of this research study is to investigate trust formation and transference in the social commerce context setting. The research is conceptually framed by relational and trust transference theories. To execute the study, a two-stage (sequential) design encompassing a quantitative as well as a randomised experimental design was employed. Firstly, trust formation was investigated with a cross-sessional questionnaire survey (stage 1) to identify key determinants of trust (cognition-based trust, affect-based trust, personality-based trust and institutional-based trust) and the consequences of a consumer’s trust beliefs in terms of trust-related behaviours. Secondly, a Solomon four-group experimental design (stage 2) was implemented to examine the impact of trust transference in an individual’s trusting behaviour towards different levels of social friends (i.e. direct friend, friend-of-friend, friend-of-friend-of-friend, and virtual friend) and different types of message framings (i.e. matched and mismatched positive and negative recommendations) in the social commerce context. In stage 1, structural equation modelling analysis using Analysis of Moment Structures (AMOS) reveals that cognition-based trust, affect-based trust, personality-based trust and institutional-based trust are significant trust domains in social commerce that encourage individuals’ trust beliefs and intention to engage in social commerce activities and social commerce adoption. Building on the first part of the study, data analysis using Braver and Braver’s meta-analytical procedure in stage 2 reveals that six scenarios show treatment effects. Analysis of Variance (ANOVA) tests show that social relations play a major role in trust transference in the social commerce context. More specifically, the recommendations (regardless whether the message is aligned or contradicted with the feedback of other experienced consumers) from strong-tie (i.e. direct friend) relationships appear to have a higher influence and usefulness to change an individual’s decision-making and belief towards a retailer.

description: We propose a theoretical framework that can possibly constrain the initial vacuum by Cosmic Microwave Background (CMB) observations. With a generic vacuum without any particular choice a priori, thereby keeping both the Bogolyubov coefficients in the analysis, we compute observable parameters from two- and three-point correlation functions. We are thus left with constraining four model parameters from the two complex Bogolyubov coefficients. We also demonstrate a method of finding out the constraint relations between the Bogolyubov coefficients using the theoretical normalization condition and observational data of power spectrum and bispectrum from CMB. Finally, we discuss the possible pros and cons of the analysis.

description: We consider inflation within a model framework where the Higgs boson arises as a pseudo-Goldstone boson associated with the breaking of a global symmetry at a scale significantly larger than the electroweak one. We show that in such a model the scalar self-couplings can be parametrically suppressed and, consequently, the non-minimal couplings to gravity can be of order one or less, while the inflationary predictions of the model remain compatible with the precision cosmological observations. Furthermore, in the model we study, the existence of the electroweak scale is entirely due to the inflaton field. Our model therefore suggests that inflation and low energy particle phenomenology may be more entwined than assumed so far.
