description: We characterize the action of isotropic pseudodifferential operators on functions in terms of their action on Hermite functions. We show that an operator $A : S(\mathbb{R}) \to S(\mathbb{R})$ is an isotropic pseudodifferential operator of order r if and only if its "matrix" $(K(A))_{m,n} := < Aϕ_n,ϕ_m>_{L^2(\mathbb{R})}$ is rapidly decreasing away from the diagonal $\{m = n\}$, order $\frac {r}{2}$ in $m + n$, and where applying the discrete difference operator along the diagonal decreases the order by one. Additionally, we use this result to prove an analogue of Beal's theorem for isotropic pseudodifferential operators.

description: The CN coma structure of the EPOXI mission target, comet 103P/Hartley 2, was observed during twenty nights from September to December 2010. These CN images probe the rotational state of the comet's nucleus and provide a ground-based observational context to complement the EPOXI observations. A dynamically excited cometary nucleus with a changing rotational rate is observed, a characteristic not seen in any comet in the past. The lack of rotational damping during the four-month observing interval places constraints on the interior structure of the nucleus.

Stack graphs: Name resolution at scale

subject: FOS: Computer and information sciences

description: We present stack graphs, an extension of Visser et al.'s scope graphs framework. Stack graphs power Precise Code Navigation at GitHub, allowing users to navigate name binding references both within and across repositories. Like scope graphs, stack graphs encode the name binding information about a program in a graph structure, in which paths represent valid name bindings. Resolving a reference to its definition is then implemented with a simple path-finding search. GitHub hosts millions of repositories, containing petabytes of total code, implemented in hundreds of different programming languages, and receiving thousands of pushes per minute. To support this scale, we ensure that the graph construction and path-finding judgments are file-incremental: for each source file, we create an isolated subgraph without any knowledge of, or visibility into, any other file in the program. This lets us eliminate the storage and compute costs of reanalyzing file versions that we have already seen. Since most commits change a small fraction of the files in a repository, this greatly amortizes the operational costs of indexing large, frequently changed repositories over time. To handle type-directed name lookups (which require "pausing" the current lookup to resolve another name), our name resolution algorithm maintains a stack of the currently paused (but still pending) lookups. Stack graphs can be constructed via a purely syntactic analysis of the program's source code, using a new declarative graph construction language. This means that we can extract name binding information for every repository without any per-package configuration, and without having to invoke an arbitrary, untrusted, package-specific build process.

Publisher: name: Zenodo
Year: 2021

description: This ongoing study focuses on the distribution patterns and drivers of deep-sea demersal and open-ocean pelagic commercial species in the SW Atlantic. Habitat Suitability Models have been structured for the valuable deep sea shrimps Aristaeopsis edwardziana, Aristeus antillensis and Aristaeomorpha foliacea, the royal crab Chaceon ramosae, the monkfish Lophius gastrophysus, and the endangered wreckfish Polyprion americanus. Species that sustain important pelagic fisheries in the South Atlantic were also chosen, namely the yellow-fin tuna (Thunnus albacares), the albacore (Thunnus alalunga) and the blue shark (Prionace glauca), as well as the critically exploited blue-fin tuna (Thunnus maccoyii) and the porbeagle shark (Lamna nasus). Species data comprise georeferenced catch and fishing effort records available from the Brazilian deep-sea fisheries observers program (2000- 2008) with a point-to-point spatial resolution, and the national tuna fisheries and ICCAT databases available from 1960 (spatial resolutions 0.5, 1 and 5°). All catch data were transformed into catch-per-unit-of-effort, subsequently modelled by Generalized Linear Models to produce species’ abundance indices. Environmental descriptors have been extracted from public databases (GEBCO, ETOPO, Copernicus and Hermes) and provided by the INALT model. Using Benthic Terrain modelling tools, bathymetry was transformed into variables that express different seafloor features, and used to segment it into structural classes. The total geographic area considered includes Santos, Campos and Espírito Santos basins. A more comprehensive analysis, however, will be conducted in Campos and Espírito Santo basins where a detailed environmental database was made available by the Brazilian oil and gas company, Petrobras.

description: We introduce Inflation, a Python library for assessing whether an observed probability distribution is compatible with a causal explanation. This is a central problem in both theoretical and applied sciences, which has recently witnessed significant advances from the area of quantum nonlocality, namely, in the development of inflation techniques. Inflation is an extensible toolkit that is capable of solving pure causal compatibility problems and optimization over (relaxations of) sets of compatible correlations in both the classical and quantum paradigms. The library is designed to be modular and with the ability of being ready-to-use, while keeping an easy access to low-level objects for custom modifications.

Shedding light on the brain—characterizing functional brain activation during simple and complex walking after stroke
Creators: name: Lim, Shannon
Publisher: name: University of British Columbia
Year: 2021

description: Independent ambulation in the community is often stated as important amongst people post-stroke. Walking within the community can be complex, requiring speed changes during walking, attention or interaction with the environment and other people. After a stroke, the ability to complete these specific walking tasks is often impaired. Currently, determining appropriate gait rehabilitation interventions post-stroke is based on clinical observations such as motor, sensory, cognitive, and balance ability. These methods, however, may not be sensitive or objective enough to detect change or appropriateness for specific interventions. Assessment of individual functional brain activation is a promising method for determining appropriateness of gait rehabilitation interventions and can provide insight on resource allocation, neural efficiency, and neural compensations. This dissertation consists of four independent studies. The first is a review of the current findings of brain activation during walking post-stroke and identified the gaps within the literature. This review then informed the next three studies where functional near-infrared spectroscopy was used to assess real-time brain activation during different types of walking: normal-paced, slow, fast, and dual-task walking. Results from these studies show task- specific activation of brain regions across the frontal and parietal cortices as well as relationships between brain activation and clinical measures of impairment and performance. Notably, consistent increases in ipsilesional prefrontal cortex was observed with each walking task, premotor cortex was involved when walking was not at a normal-pace, and activation in sensorimotor and posterior parietal cortices related to gait speed. Results from these studies contribute basic scientific knowledge towards the neural correlates of walking after a stroke and can be an important reference for future interventions aimed to improve walking recovery.

description: We study transport in the free fermionic one-dimensional systems subjected to arbitrary local potentials. The bias needed for the transport is modeled by the initial highly non-equilibrium distribution where only half of the system is populated. Additionally to that, the local potential is also suddenly changed when the transport starts. For such a quench protocol we compute the Full Counting Statistics (FCS) of the number of particles in the initially empty part. In the thermodynamic limit, the FCS can be expressed via the Fredholm determinant with the kernel depending on the scattering data and Jost solutions of the pre-quench and the post-quench potentials. We discuss the large-time asymptotic behavior of the obtained determinant and observe that if two or more bound states are present in the spectrum of the post-quench potential the information about the initial state manifests itself in the persistent oscillations of the FCS. On the contrary, when there are no bound states the asymptotic behavior of the FCS is determined solely by the scattering data of the post-quench potential, which for the current (the first moment) is given by the Landauer--Büttiker formalism. The information about the initial state can be observed only in the transient dynamics.

description: We consider the design of photonic circuits that make use of Ti:LiNbO$_{3}$ diffused channel waveguides for generating photons with various combinations of modal, spectral, and polarization entanglement. Down-converted photon pairs are generated via spontaneous optical parametric down-conversion (SPDC) in a two-mode waveguide. We study a class of photonic circuits comprising: 1) a nonlinear periodically poled two-mode waveguide structure, 2) a set of single-mode and two-mode waveguide-based couplers arranged in such a way that they suitably separate the three photons comprising the SPDC process, and, for some applications, 3) a holographic Bragg grating that acts as a dichroic reflector. The first circuit produces frequency-degenerate down-converted photons, each with even spatial parity, in two separate single-mode waveguides. Changing the parameters of the elements allows this same circuit to produce two nondegenerate down-converted photons that are entangled in frequency or simultaneously entangled in frequency and polarization. The second photonic circuit is designed to produce modal entanglement by distinguishing the photons on the basis of their frequencies. A modified version of this circuit can be used to generate photons that are doubly entangled in mode number and polarization. The third photonic circuit is designed to manage dispersion by converting modal, spectral, and polarization entanglement into path entanglement.

description: We propose a polarization modulation scheme of electromagnetic (EM) waves through reflection of a tunable metamaterial reflector/absorber. By constructing the metamaterial with resonant unit cells coupled by diodes, we demonstrate that the EM reflections for orthogonal polarized incident waves can be tuned independently by adjusting the bias voltages on the corresponding diodes. Owing to this feature, the reflected EM waves can be electrically controlled to a linear polarization with continuously tunable azimuth angle from 0o to 90o at the resonant frequency, or an elliptical polarization with tunable azimuth angle of the major axis when off the resonant frequency. The proposed property has been verified through both numerical simulations and experimental measurements at microwave band, which enables us to electrically modulate the polarization state of EM waves flexibly.

Distributed algorithms

description: We depend upon distributed systems in every aspect of life. Distributed consensus, the ability to reach agreement in the face of failures and asynchrony, is a fundamental and powerful primitive for constructing reliable distributed systems from unreliable components. For over two decades, the Paxos algorithm has been synonymous with distributed consensus. Paxos is widely deployed in production systems, yet it is poorly understood and it proves to be heavyweight, unscalable and unreliable in practice. As such, Paxos has been the subject of extensive research to better understand the algorithm, to optimise its performance and to mitigate its limitations. In this thesis, we re-examine the foundations of how Paxos solves distributed consensus. Our hypothesis is that these limitations are not inherent to the problem of consensus but instead specific to the approach of Paxos. The surprising result of our analysis is a substantial weakening to the requirements of this widely studied algorithm. Building on this insight, we are able to prove an extensive generalisation over the Paxos algorithm. Our revised understanding of distributed consensus enables us to construct a diverse family of algorithms for solving consensus; covering classical as well as novel algorithms to reach consensus where it was previously thought impossible. We will explore the wide reaching implications of this new understanding, ranging from pragmatic optimisations to production systems to fundamentally novel approaches to consensus, which achieve new tradeoffs in performance, scalability and reliability.
The development of peer social support networks among families of children with neurodevelopmental and intellectual disabilities attending physical activity programs
Creators: name: Chakraborti, Michelle
Publisher: name: University of British Columbia
Year: 2021

description: According to the World Health Organization, “family” is an important contextual factor for childcare and development of children with neurodevelopmental and intellectual disabilities (NDID). However, caregiving-related stressors result in multiple challenges, contributing towards the families’ social isolation and distress. This further affects families’ quality of life, mental health and ultimately childcare. Peer support networks represent established strategies for social integration; however, families are often unable to attend these networks due to unavailable time and childcare resources. Therefore, ways to socially integrate families, while simultaneously supporting the child are warranted. Community-based adapted physical activity programs (PA programs) represent a promising approach. This thesis investigated the potential of peer support network development at PA programs, their impact on the families’ quality of life, resilience and empowerment and relative importance compared to other peer support networks. A mixed-methods approach was implemented where quantitative information for the cross-sectional study was collected using standardized scales on perceived social support, family quality of life, resilience, and self-efficacy and qualitative information was collected using semi-structured interviews and ethnographic observation. Fifty families having a child with NDID participated from twenty-two programs across British Columbia. Interviews demonstrated network formation was facilitated by the presence of families at the PA program that provided them with valuable time to interact with other parents. The regularity of the programs’ schedule, and its duration were important factors. Moreover, the presence of children with similar abilities facilitated the child’s friendship development, which appeared to be a motivation for parents to form networks. Parental networks developed in two ways, through their child’s friendship’s resulting in parental interactions and through direct parent-parent engagement on site. Emergent themes illustrated networks promoted families’ sense of community, offered emotional and informational support, helped families developing resiliency and empowered them. However, all these elements were not well-captured by the standard scales. Finally, seventy percent families ranked these PA-related networks as ‘important’ compared to other peer networks, as simultaneously, parents benefit from socialising while their child from activities. Overall, evidence demonstrated the unique benefit of these programs that potentially strengthen both families and children simultaneously. Ultimately, strengthened families deliver better childcare.
Beyond Fisher Forecasting for Cosmology

description: The planning and design of future experiments rely heavily on forecasting to assess the potential scientific value provided by a hypothetical set of measurements. The Fisher information matrix, due to its convenient properties and low computational cost, provides an especially useful forecasting tool. However, the Fisher matrix only provides a reasonable approximation to the true likelihood when data are nearly Gaussian distributed and observables have nearly linear dependence on the parameters of interest. Also, Fisher forecasting techniques alone cannot be used to assess their own validity. Thorough sampling of the exact or mock likelihood can definitively determine whether a Fisher forecast is valid, though such sampling is often prohibitively expensive. We propose a simple test, based on the Derivative Approximation for LIkelihoods (DALI) technique, to determine whether the Fisher matrix provides a good approximation to the exact likelihood. We show that the Fisher matrix becomes a poor approximation to the true likelihood in regions where two-dimensional slices of level surfaces of the DALI approximation to the likelihood differ from two-dimensional slices of level surfaces of the Fisher approximation to the likelihood. We demonstrate that our method accurately predicts situations in which the Fisher approximation deviates from the true likelihood for various cosmological models and several data combinations, with only a modest increase in computational cost compared to standard Fisher forecasts.

The reaction source $f(x,u)$ is a radial function with respect to $x$ and it is critical in view of exponential inequality of Adams' type. The existence result is proved by using the constrained minimization in Nehari set coupled with the quantitative deformation lemma and degree theory results.

description: Pavement cells in the leaf epidermis can exhibit a wide variety of shapes. Undulations in the anticlinal cell wall are a particularly interesting feature present in many model species: for example, Arabidopsis thaliana, tobacco and maize; but absent in others, like Brachypodium distachyon. Epidermal cell patterning is qualitatively similar between individuals of the same species but different species can have wildly different shapes and there is no comprehensive data set available for epidermal cell shapes. Moreover, the cell shape changes during development – this has only been quantitatively studied in Arabidopsis. This work presents and analyses three sets of cell shape data. The first part examines the morphogenesis of the curiously shaped pavement cells of maize leaves – these cells are highly elongated and form deep undulations in the anticlinal wall as they mature. The second part analyses the cell shapes of more than 200 species and concludes that strong undulations like those observed in Arabidopsis and maize are quite extreme: 95% of the species examined develop more shallow undulations or none at all. This part also investigates the extent to which cell shape features correlate with leaf shape features and the phylogenetic distance. The third part studies more subtle variances in the patterning of the cotyledons of different Arabidopsis thaliana ecotypes. Analysing cell shapes also poses an interesting mathematical challenge: quantifying two- dimensional shapes is a nontrivial mathematical problem as it requires representing the information defined by the coordinates of the outline by only a few quantities. Throughout this project, different metrics have been used alongside principal component analysis to reduce the number of variables. These metrics include traditional morphometric variables, elliptic Fourier descriptors and various other state-of-the-art methods for shape characterisation.

description: We study the magnetic phase diagram of an ensemble of dipolar hard spheres (DHS) with or without uniaxial anisotropy and frozen in position on a disordered structure by tempered Monte Carlo simulations. The crucial point is to consider an anisotropic structure, obtained from the liquid state of the dipolar hard spheres fluid, frozen in its polarized state at low temperature. The freezing inverse temperature $β_f$ determines the degree of anisotropy of the structure which is quantified through a structural nematic order parameter, $λ_s$. The case of the non zero uniaxial anisotropy is considered only in its infinitely strong strength limit where the system transforms in a dipolar Ising model (DIM). The important finding of this work is that both the DHS and the DIM with a frozen structure build in this way present a ferromagnetic phase at volume fractions below the threshold value where the corresponding isotropic DHS systems exhibit a spin glass phase at low temperature.

description: Lithium niobate photonic circuits have the salutary property of permitting the generation, transmission, and processing of photons to be accommodated on a single chip. Compact photonic circuits such as these, with multiple components integrated on a single chip, are crucial for efficiently implementing quantum information processing schemes. We present a set of basic transformations that are useful for manipulating modal qubits in Ti:LiNbO$_3$ photonic quantum circuits. These include the mode analyzer, a device that separates the even and odd components of a state into two separate spatial paths; the mode rotator, which rotates the state by an angle in mode space; and modal Pauli spin operators that effect related operations. We also describe the design of a deterministic, two-qubit, single-photon, CNOT gate, a key element in certain sets of universal quantum logic gates. It is implemented as a Ti:LiNbO$_3$ photonic quantum circuit in which the polarization and mode number of a single photon serve as the control and target qubits, respectively. It is shown that the effects of dispersion in the CNOT circuit can be mitigated by augmenting it with an additional path. The performance of all of these components are confirmed by numerical simulations. The implementation of these transformations relies on selective and controllable power coupling among single- and two-mode waveguides, as well as the polarization sensitivity of the Pockels coefficients in LiNbO$_3$.

description: Axion haloscopes search for dark matter axions from the galactic halo, most commonly by measuring a power excess sourced by the axion effective current density. Constraining axion parameters from detection or lack thereof requires estimating the expected signal power. Often, this is done by studying the response of the haloscope to a known, but different, source current density, for example via a reflection measurement. However, only in the special case when both sources induce the same electromagnetic fields, do the quantities derived from a reflection measurement adequately describe the setup during an axion measurement. While this might be valid for the traditional resonant cavity haloscope, new broadband or open designs like dish antennas or dielectric haloscopes cannot make this assumption. A more general relation between axion- and reflection-induced fields is needed. In this article, we use the Lorentz reciprocity theorem to derive an expression for the axion signal power which instead of the unmeasurable axion-induced fields depends on the measurable reflection-induced fields. This entirely circumvents the need to know the response of the haloscope to the unknown axion source. It applies to a wide variety of haloscopes including resonant cavities, dielectric haloscopes, and broadband dish antennas.

description: We simplify and complete the construction of fully $O(D)$-equivariant fuzzy spheres $S^d_L$, for all dimensions $d\equiv D-1$, initiated in [G. Fiore, F. Pisacane, J. Geom. Phys. 132 (2018), 423]. This is based on imposing a suitable energy cutoff on a quantum particle in $\mathbb{R}^D$ in a confining potential well $V(r)$ with a very sharp minimum on the sphere of radius $r=1$; the cutoff and the depth of the well diverge with $L\in\mathbb{N}$. As a result, the noncommutative Cartesian coordinates $\overline{x}^i$ generate the whole algebra of observables $A_L$ on the Hilbert space $H_L$; $H_L$ can be recovered applying polynomials in the $\overline{x}^i$ to any of its elements. The commutators of the $\overline{x}^i$ are proportional to the angular momentum components, as in Snyder noncommutative spaces. $H_L$, as carrier space of a reducible representation of $O(D)$, is isomorphic to the space of harmonic homogeneous polynomials of degree $L$ in the Cartesian coordinates of (commutative) $\mathbb{R}^{D+1}$, which carries an irreducible representation ${\bfπ}_L$ of $O(D+1)\supset O(D)$. Moreover, $A_L$ is isomorphic to ${\bfπ}_L\left(Uso(D+1)\right)$. We resp. interpret $\{H_L\}_{L\in\mathbb{N}}$, $\{A_L\}_{L\in\mathbb{N}}$ as fuzzy deformations of the space $H_s:={\cal L}^2(S^d)$ of (square integrable) functions on $S^d$ and of the associated algebra $A_s$ of observables, because they resp. go to $H_s,A_s$ as $L$ diverges (with $\hbar$ fixed). With suitable $\hbar=\hbar(L)\stackrel{L\to\infty}{\longrightarrow} 0$, in the same limit $A_L$ goes to the (algebra of functions on the) Poisson manifold $T^*S^d$; more formally, $\{A_L\}_{L\in\mathbb{N}}$ yields a fuzzy quantization of a coadjoint orbit of $O(D+1)$ that goes to the classical phase space $T^*S^d$.

PAMELA's cosmic positron from decaying LSP in SO(10) SUSY GUT

description: We propose two viable scenarios explaining the recent observations on cosmic positron excess. In both scenarios, the present relic density in the Universe is assumed to be still supported by thermally produced WIMP or LSP (χ). One of the scenarios is based on two dark matter (DM) components (χ,X) scenario, and the other is on SO(10) SUSY GUT. In the two DM components scenario, extremely small amount of non-thermally produced meta-stable DM component [O(10^{-10}) < n_X /n_χ] explains the cosmic positron excess. In the SO(10) model, extremely small R-parity violation for LSP decay to e^\pm is naturally achieved with a non-zero VEV of the superpartner of one right-handed neutrino (\tildeν^c) and a global symmetry.

A consistent volume-of-fluid approach for direct numerical simulation of the aerodynamic breakup of a vaporizing drop

description: A novel simulation framework has been developed in this study for the direct numerical simulation of the aerodynamic breakup of a vaporizing drop. The interfacial multiphase flow with phase change is resolved using a consistent geometric volume-of-fluid method. The bulk fluids are viscous and incompressible with surface tension at the interface. The newly-developed numerical methods have been implemented in the Basilisk solver, in which the adaptive octree/quadtree mesh is used for spatial discretization, allowing flexibility in dynamically refining the mesh in a user-defined region. The simulation framework is extensively validated by a series of benchmark cases, including the 1D Stefan and sucking problems, the growth of a 3D spherical bubble in a superheated liquid, and a 2D film boiling problem. The simulation results agree very well with the exact solution and previous numerical studies. 2D axisymmetric simulations were performed to resolve the vaporization of a moving drop with a low Weber number in a high-temperature free stream. The computed rate of volume loss agrees well with the empirical model of drop evaporation. Finally, the validated solver is used to simulate the aerodynamic breakup of an acetone drop at a high Weber number. A fully 3D simulation is performed and the morphological evolution of the drop is accurately resolved. The rate of vaporization is found to be significantly enhanced due to the drop deformation and breakup. The drop volume decreases nonlinearly in time and at a much higher rate than the empirical correlation for a spherical drop.

description: In the scenario in which QCD axion dark matter is produced after inflation, the Universe is populated by large inhomogeneities on very small scales. Eventually, these fluctuations will collapse gravitationally to form dense axion miniclusters that trap up to $\sim$75% of the dark matter within asteroid-mass clumps. Axion miniclusters are physically tiny however, so haloscope experiments searching for axions directly on Earth are much more likely to be probing ``minivoids'' -- the space in between miniclusters. This scenario seems like it ought to spell doom for haloscopes, but while these minivoids might be underdense, they are not totally devoid of axions. Using Schrödinger-Poisson and N-body simulations to evolve from realistic initial field configurations, we quantify the extent to which the local ambient dark matter density is suppressed in the post-inflationary scenario. We find that a typical experimental measurement will sample an axion density that is only around 10% of the expected galactic dark matter density. Our results also have implications for experimental campaigns lasting longer than a few years, as well as broadband haloscopes that have sensitivity to transient signatures. We show that for a $\mathcal{O}$(year)-long integration times, the measured dark matter density should be expected to vary by 20--30%.

description: In gold-gold collisions of the Relativistic Heavy Ion Collider (RHIC) a perfect fluid of quarks, sometimes called the strongly interacting quark gluon plasma (sQGP) is created for an extremely short time. The time evolution of this fluid can be described by hydrodynamical models. After expansion and cooling, the freeze-out happens and hadrons are created. Their distribution reveals information about the final state of the fluid. To investigate the time evolution one needs to analyze penetrating probes, such as direct photon observables. Transverse momentum distributions of low energy direct photons were mesured in 2010 by PHENIX, while azimuthal asymmetry in 2011. These measurements can be compared to hydrodynamics to determine the equation of state and the initial temperature of sQGP. In this paper we analyze an 1+3 dimensional solution of relativistic hydrodynamics. We calculate momentum distribution, azimuthal asymmetry and momentum correlations of direct photons. Based on earlier fits to hadronic spectra, we compare photon calculations to measurements to determine the equation of state and the initial temperature of sQGP. We find that the initial temperature in the center of the fireball is 507+-12 MeV, while for the sound speed we get a speed of sound of 0.36+-0.02. We also estimate a systematic error of these results. We find that the measured azimuthal asymmetry is also not incompatible with this model, and predict a photon source that is significantly larger in the out direction than in the side direction.

description:  Τα τελευταία χρόνια, η αυξανόμενη ανησυχία που προκαλεί η Παγκόσμια κλιματική αλλαγή αλλά και η συνεπακόλουθη ανάγκη για  την διατήρηση των συμβατικών ενεργειακών αποθεμάτων, έχει στρέψει τις μεγάλες αυτοκινητοβιομηχανίες στην προώθηση και βελτίωση των ηλεκτροκίνητων οχημάτων (υβριδικών και μη-). Ωστόσο, η αλλαγή της κατεύθυνσης αυτής προς την ηλεκτροκίνηση, επιφέρει μία πρόσθετη πρόκληση στον τομέα εφαρμογής των ηλεκτρικών δικτύων: Τα νέα αυτά ηλεκτρικά δίκτυα θα κληθούν να διαχειριστούν με βέλτιστο τρόπο το διαθέσιμο ηλεκτρικό φορτίο των οχημάτων ανά ημέρα.
Η τεχνολογία αμφίδρομης ροής ισχύος μεταξύ οχημάτων-δικτύου «Vehicle-to-Grid, V2G», περιγράφει μία (κατά κάποιο τρόπο) συνδεσμολογία όπου ηλεκτρικά οχήματα με μπαταρίες (BEV), υβριδικά οχήματα (PHEV) ή ηλεκτρικά οχήματα με κυψέλες καυσίμου υδρογόνου, επικοινωνούν με το ηλεκτρικό δίκτυο (συμβατικό ή με χρήση ΑΠΕ), πουλώντας υπηρεσίες ανταπόκρισης στην ζήτηση. Με άλλα λόγια, τα οχήματα αυτά ανάλογα με την κατάσταση φόρτισης τους και τους στόχους της βέλτιστης αξιοποίησης ενέργειας (π.χ. φόρτιση οχημάτων, μηδενική ζήτηση από το δίκτυο), προσφέρουν ηλεκτρική ενέργεια στο δίκτυο ή μειώνουν το ρυθμό φόρτισής τους.
Στα ανωτέρω πλαίσια, η παρούσα διπλωματική εργασία στοχεύει στην ανάδειξη των προτερημάτων της τεχνολογίας «V2G», μέσω της ανάπτυξης ενός αλγορίθμου βελτιστοποίησης της κατανομής φόρτισής τους. Ειδικότερα, ο αλγόριθμος αυτός θα συμβάλει στην ομαλότερη λειτουργία του ηλεκτρικού δικτύου, όπου θα επιβλέπει α) τα οχήματα που θα δύναται να φορτίζουν, β) τα οχήματα που θα δύναται να εκφορτίζουν και γ) τις ανάγκες ζήτησης/προσφοράς δικτύου ανά ημέρα.
Ο αλγόριθμος που αναπτύχθηκε για την κατανομή του επιπρόσθετου φορτίου των ηλεκτρικών οχημάτων με στόχο την ελαχιστοποίηση της ζητούμενης ισχύος κατά τις ώρες αιχμής, κατάφερε να βελτιστοποιήσει την λειτουργία φόρτισης/αποφόρτισης σε 215 οχήματα των οποίων το φορτίο κλήθηκε να καλύψει ο υποσταθμός των Βρυσών (case study) στον Δήμο Αποκορώνου. Συγκεκριμένα, κατάφερε να περιορίσει την αύξηση του φορτίου αιχμής (σε μία τυπική ημέρα, Κυριακή του έτους 2020) στα 48 kW ενώ χωρίς την ύπαρξή του και της τεχνολογίας V2G η αύξηση θα ήταν 2080 kW. Σημαντική επιτυχία αποτέλεσε το γεγονός ότι το μέγιστο ημερήσιο φορτίο είναι ίσο με αυτό της περίπτωσης που δεν υπάρχει κανένα ηλεκτρικό όχημα στην περιοχή, φανερώνοντας την άριστη εφαρμογή του αλγορίθμου.
