description: Stream join consists one of the most resource-intensive operators in stream processing. Due to this characteristic, a big interest has been created in building high throughput and low latency systems which will be able to process real-time, bursty and rate varying data streams. This thesis proposes an FPGA-based architecture which is based on one of the most efficient stream join algorithms, i.e ScaleJoin. The proposed architecture extends the first hardware-based architecture of the ScaleJoin algorithm. The first hardware implementation achieves high throughput and scalability but suffers from low resources utilization. In this thesis, we propose a novel architecture to achieve greater level of parallelism and exploit the available resources. Our system runs on Convey HC-2ex hybrid computer equipped with two six-core Intel Xeon E5-2640 processors running at 2.5 GHz and four Virtex 6 LX760 FPGAs. The experimental performance evaluation shows that our system totally outperforms the corresponding software-based solution and improves greatly the performance of the first hardware implementation.
description: To stream join αποτελεί μία από τις πιο απαιτητικές διεργασίες όσον αφορά το stream processing. Λόγω αυτού του χαρακτηριστικού, έχει δημιουργηθεί μεγάλο ενδιαφέρον για τη δημιουργία συστημάτων υψηλής απόδοσης και χαμηλού χρόνου καθυστέρησης, τα οποία θα είναι σε θέση να επεξεργάζονται μεγάλο όγκο streaming δεδομένων σε πραγματικό χρόνο. Η συγκεκριμένη διπλωματική εργασία προτείνει μια αρχιτεκτονική σε FPGA, που βασίζεται σε έναν από τους πιο αποδοτικούς stream join αλγορίθμους, τον ScaleJoin, και επεκτείνει την πρώτη hardware υλοποίηση του. Η πρώτη hardware υλοποίηση πετυχαίνει υψηλή απόδοση και επεκτασιμότητα αλλά πάσχει απο χαμηλή χρήση των διαθέσιμων πορων. Σε αυτή τη διπλωματική προτείνουμε μία νέα αρχιτεκτονική, με σκοπό την επίτευξη μεγαλύτερου επιπέδου παραλληλίας και την αξιοποίηση, όσο το δυνατόν περισσότερο, των διαθέσιμων πόρων του συστήματος. Το σύστημά μας λειτουργεί στον υβριδικό υπολογιστή Convey HC-2ex ο οποίος είναι εφοδιασμένος με 2 εξαπύρηνους Intel Xeon E5-2640 και 4 FPGAs Virtex 6 LX760. Η αξιολόγηση της απόδοσης δείχνει ότι το σύστημα μας υπερτερεί τόσο της αντίστοιχης software υλοποίησης, όσο και της πρώτης hardware υλοποίησης του ScaleJoin αλγορίθμου.

description: The making of maps is no longer restricted to the rarefied realm of cartographers. Students, scholars, and researchers in all fields have recognized the power that maps can bring to data of many kinds. Architectural scholars can integrate digitized historical maps and demographic datasets to analyze changes over time in different neighborhoods; oceanographers can marry the bathymetric measurements to the configuration of the coastline and layer that with storm-related data to estimate storm surge in coastal communities. A historian explores geopolitical change over time, by layering political boundary lines and other features over a map of Africa. Thanks to easily available mapping software, it is increasingly easy to experiment with and build mapping projects to answer questions and share data. And yet, many of the tools and platforms that make this possible are part of for-profit businesses, such as Google or ESRI. Others, like Mapzen, are open source, but subject to the same vagaries of many small organizations. Started in 2014 with over 70,000 users, Mapzen announced in 2018 that it would be ceasing operations, and its team disbanded, off to continue developing parts of the code, in the service of other organizations. Scholars and others in the academic sector whose work is built using these tools and platforms need solutions they can rely on to endure. On May 30 and 31, 2019, Columbia University Libraries convened a group of 26 experts, practitioners, developers, and project leads from a range of disciplines to discuss the sustainability and preservation challenges specific to web-based digital mapping projects. The meeting was designed as a series of discussions, brainstorming, and planning exercises, with the aim of identifying the issues and scope concerning the sustainability and preservation of web-based digital mapping projects. Workshop leaders sought to identify specific challenges, as well as some concrete types of solutions that might begin to address them. The findings of the workshop and post-workshop survey suggest a deep and growing interest not only in mapping tools for academia, but in exploring ways in which the academy itself can play an active and strategic role in supporting them. Certain details in our recommendations will be expanded in an addendum to this white paper after an in-person meeting of several Task Force members in January 2020 to continue developing the solutions outlined in that meeting, particularly the best practice/guidance and infrastructure solutions. This will be enabled by a no-cost extension on the Andrew W. Mellon Foundation grant that supported the conference.

description: The electron gas inside a neutron star is highly degenerate and relativistic. Due to the electron-electron magnetic interaction, the differential susceptibility can equal or exceed 1, which causes the magnetic system of the neutron star to become metastable or unstable. The Fermi liquid of nucleons under the crust can be in a metastable state, while the crust is unstable to the formation of layers of alternating magnetization. The change of the magnetic stress acting on adjacent domains can result in a series of shifts or fractures in the crust. The releasing of magnetic free energy and elastic energy in the crust can cause the bursts observed in magnetars. Simultaneously, a series of shifts or fractures in the deep crust which is closed to the Fermi liquid of nucleons can trigger the phase transition of the Fermi liquid of nucleons from a metastable state to a stable state. The released magnetic free energy in the Fermi liquid of nucleons corresponds to the giant flares observed in some magnetars.

description: The abelian Higgs model on a compact Riemann surface Σsupports vortex solutions for any positive vortex number d \in \ZZ. Moreover, the vortex moduli space for fixed d has long been known to be the symmetrized d-th power of Σ, in symbols, \Sym^d(Σ). This moduli space is Kahler with respect to the physically motivated metric whose geodesics describe slow vortex motion. In this paper we appeal to classical properties of \Sym^d(Σ) to obtain new results for the moduli space metric. Our main tool is the Abel-Jacobi map, which maps \Sym^d(Σ) into the Jacobian of Σ. Fibres of the Abel-Jacobi map are complex projective spaces, and the first theorem we prove states that near the Bradlow limit the moduli space metric restricted to these fibres is a multiple of the Fubini-Study metric. Additional significance is given to the fibres of the Abel-Jacobi map by our second result: we show that if Σis a hyperelliptic surface, there exist two special fibres which are geodesic submanifolds of the moduli space. Even more is true: the Abel-Jacobi map has a number of fibres which contain complex projective subspaces that are geodesic.

description: We consider Z2 spin liquids on the kagome lattice on the verge of a valence bond solid (VBS) transition, where vortex excitations carrying Z2 magnetic flux - so-called visons - condense. We show that these vison excitations can couple directly to the external electromagnetic field, even though they carry neither spin nor charge. This is possible via a magneto-elastic coupling mechanism recently identified by Potter et al and Hao. For the case of transitions to a 36-site unit cell VBS state the corresponding finite ac-conductivity has a specific power law frequency dependence, which is related to the crossover exponent of the quantum critical point. The visons' contribution to the optical conductivity at transitions to VBS states with a 12-site unit cell vanishes, however.
Pseudolikelihood Decimation Algorithm Improving the Inference of the Interaction Network in a General Class of Ising Models

description: In this Letter we propose a new method to infer the topology of the interaction network in pairwise models with Ising variables. By using the pseudolikelihood method (PLM) at high temperature, it is generally possible to distinguish between zero and nonzero couplings because a clear gap separate the two groups. However at lower temperatures the PLM is much less effective and the result depends on subjective choices, such as the value of the $\ell_1$ regularizer and that of the threshold to separate nonzero couplings from null ones. We introduce a decimation procedure based on the PLM that recursively sets to zero the less significant couplings, until the variation of the pseudolikelihood signals that relevant couplings are being removed. The new method is fully automated and does not require any subjective choice by the user. Numerical tests have been performed on a wide class of Ising models, having different topologies (from random graphs to finite dimensional lattices) and different couplings (both diluted ferromagnets in a field and spin glasses). These numerical results show that the new algorithm performs better than standard PLM

description: The goal of this project was to create a realistic 3D car driving simulator to be used for neuroscientific experimentation, in collaboration with the Brighton and Sussex Medical School. This project actually builds on earlier work at the Brighton and Sussex Medical School which shows that although many studies suggest that perceptual processing, particularly to painful stimuli, tend to be inhibited at cardiac systole, fear detection and processing is selectively enhanced at systole.

A photorealistic driving simulator has been implemented, displayed on an Oculus Head Mounted Display, controlled by an actual wheel interface and pedals. The software is programmed in Unity and communicated a realistic experience of a driving a car on an endless road in nature. A steering wheel as well as controlling pedals have been integrated in the application calibrated in terms of the efficiency and sensitivity in order to achieve a simulation environment which is as close as possible to realistic driving.

A highly accurate method of monitoring the heart rate of individuals put forward while users are driving. An oximeter attached to the earlobe was integrated in the application and was synchronized by 95% accuracy with an Electrocardiogram attached to the chest. Cardiac timing detection provides input to the driving simulator developed from scratch, which in turn, guides the occurrences of threat-inducing events while a user is immersed in a synthetic environment. These events appear at distinct points of the heart rate, either at cardiac systole or at cardiac diastole. It is important to determine if the reactions of the users are induced faster at cardiac systole when the baroreceptors are fired, or at cardiac diastole when the baroreceptors are quiet. These occurrences of threat-inducing events consist of:  living obstacles such as horses, human-beings and non-living obstacles such as barrels.

description:         Αντικείμενο της διπλωματικής εργασίας αποτελεί ο σχεδιασμός ενός πάρκου παιχνιδιού για παιδιά με αυτισμό, το οποίο απευθύνεται σε ένα εύρος ηλικιών, από την προσχολική μέχρι και την εφηβεία. Η πρόταση λαμβάνει χώρα στο άλσος της Νέας Σμύρνης στην Αθήνα.
Μέσα από την συγκέντρωση βιβλιογραφικού και θεωρητικού υλικού, έχει γίνει κατανοητό ότι η σημασία του παιχνιδιού, που είναι αυθόρμητο, ευχάριστο και διασκεδαστικό για όλα τα παιδιά, δεν είναι η ίδια για τα παιδιά με αυτισμό, τα οποία απομονώνονται κοινωνικά και παίζουν λιγότερο, επιδεικνύοντας περιορισμένο ‘’λειτουργικό’’ παιχνίδι. Παρατηρείται ότι τα χωρικά περιβάλλοντα που αναφέρονται στον αυτισμό τοποθετούνται συνήθως σε κλειστούς, πιο εύκολα διαχειρίσιμους χώρους, οι οποίοι  όμως απομονώνουν το ‘’αυτιστικό’’ υποκείμενο. Δεδομένων των προαναφερθέντων, πρωταρχικός στόχος της εργασίας ήταν η επιλογή ενός εξωτερικού περιβάλλοντος παιχνιδιού, όπου το παιδί αποκτά επαφή με το φυσικό στοιχείο και συμμετέχει στην παράλληλη δραστηριότητα και άλλων ανθρώπων στο χώρο. Η επιλεγμένη περιοχή μελέτης συνδυάζει το φυσικό με το αστικό στοιχείο και η κλίμακα της επιτρέπει την ικανοποίηση της ανάγκης του αυτιστικού χρήστη για ‘’διαμερισματοποίηση’’ δραστηριοτήτων και επιλεγμένη κοινωνικοποίηση με άλλους επισκέπτες, μέσω της παρατήρησης.
      Σε μία προσπάθεια εξέλιξης των γνωστικών, κοινωνικών  δεξιοτήτων και δεξιοτήτων παιχνιδιού, επιλέχτηκαν τρία εργαλεία-είδη παιχνιδιού, το ελεύθερο-δομημένο, το μουσικό και το θεατρικό. Η σύνθεση οργανώνεται σε τρεις πυρήνες παιχνιδιού, οι οποίοι αναφέρονται σε διαφορετικούς παιδαγωγικούς στόχου, ενώ  συνδυαστικά μπορούν να συγκροτήσουν ένα ολοκληρωμένο μοντέλο προσέγγισης, συνθέτοντας τελικά ένα πολυαισθητηριακό περιβάλλον παιχνιδιού. Λαμβάνοντας υπόψιν την ποικιλομορφία των ερεθισμάτων και αντιδράσεων των παιδιών στο χώρο καθώς και την αυξημένη ανάγκη τους για ιδιωτικότητα , δημιουργούνται υπαίθριοι και ημιυπαίθριοι χώροι, μικρότερης και μεγαλύτερης κλίμακας, σε συνδυασμό με χώρους απομόνωσης, όπου μπορούν να καταφύγουν σε περίπτωση ‘’υπερτροφοδότησης’’. Σχεδιάζονται εστιασμένα κατασκευές παιχνιδιού μικρής κλίμακας, , οι οποίες στοχεύουν στην εξερεύνηση – οικειοποίηση του χώρου, στην επεξεργασία ερεθισμάτων και στην ανάπτυξη ψυχοκινητικής, δημιουργικής φαντασίας και κοινωνικών δεξιοτήτων.

description: We numerically investigated the entanglement product in the simplest coupled kicked top model with the spin $j=1$. Different from the dynamical pattern of entanglement in the semiclassical regime, two similar initial states may have discordant entanglement oscillations. A candidate of the quantum signature of this classical chaotic system was proposed. The potential antimonotonic relation between the rank correlation coefficient qualifying the concordant of two entanglement evolutions and the stationary entanglement was preliminarily revealed.

description: Epidemics of infectious disease can have deleterious effects on economic development except mitigated through global health governance and domestic institutions. We investigate this hypothesis by examining the effects of sudden exposure to meningitis on economic outcomes using evidence from the meningitis belt in sub-Saharan Africa. Meningitis shocks reduce economic activity and child health outcomes in periods when the World Health Organization (WHO) does not declare an epidemic year. These effects are reversed when the WHO declares an epidemic year. A primary mechanism explaining the heterogeneity in results may be the influx of donor aid when the WHO declares an epidemic year. We document an increase in World Bank health aid projects approved during epidemic years. Areas that receive more health aid have more economic activity though health projects funded during epidemic years are rated relatively worse by independent evaluators. Domestic institutions influence resource distribution, with regions that are co-ethnic with the president having better outcomes than non-co-ethnic areas. The results are robust to extensive controls and using the timing of the Islamic Hajj to instrument for meningitis shocks.

 Η παρούσα διπλωματική έχει ως στόχο την ενεργοποίηση του παλιού εργοστασιακού συγκροτήματος, μέσω της αξιοποίησης του κτιριακού αποθέματος του και των ανοικτών του χώρων, ως μέσο μετάβασης από το κέντρο της πόλης στο παραλιακό της μέτωπο. Τα κτιριακά κατάλοιπα του Κρόνου αντιμετωπίσθηκαν με σεβασμό ως προς την ιστορία τους, και για την επανάχρηση τους επιλέχθηκαν υπερτοπικές και τοπικές χρήσεις, πολιτισμού, κοινής ωφελείας και αναψυχής με στόχο την αύξηση της επισκεψιμότητας της περιοχής αλλά και την πολιτιστική αναβάθμιση της. Παράλληλα, σχεδιάστηκε η ανάπλαση της παραλιακής ζώνης, όπου εμπλουτίσθηκε με πολιτιστικές λειτουργίες, χώρους αναψυχής, στάσης και πρασίνου.

description: We use the expansion-normalized variables approach to study the dynamics of a non-tilted Bianchi Type I cosmological model with both a homogeneous magnetic field and a viscous fluid. In our model the perfect magnetohydrodynamic approximation is made, and both bulk and shear viscous effects are retained. The dynamical system is studied in detail through a fixed-point analysis which determines the local sink and source behavior of the system. We show that the fixed points may be associated with Kasner-type solutions, a flat universe FLRW solution, and interestingly, a new solution to the Einstein Field equations involving non-zero magnetic fields, and non-zero viscous coefficients. It is further shown that for certain values of the bulk and shear viscosity and equation of state parameters, the model isotropizes at late times.

description: A Crescent shaped prominence Structure (CS), over the solar west limb is studied using EIS/HINODE and AIA/SDO. First, the time varying positions of the top and below borders of the CS, along with its central axis are derived. Time evolutions of the Doppler shifts, and Line width of Fe~{\scriptsize \rm XII} 195.119 line are studied over the CS borders. Transverse kink oscillations are observed both in the Solar-Y direction and in the Doppler shifts over the observers' LOS. One explanation could be the oscillatory direction of the main kink wave build an angle with the observers LOS. This angle is calculated to be equal to 27 degrees for the CS top border. The main kink amplitude velocity and periods are obtained to be 5.3 $\rm km/s$, and 33.4 minutes, respectively. The anti-correlation observed between the brightness and thickness of the CS (with -178.1$^\circ$) suggests the presence of sausage modes with periods of 20.8 minutes. Based on the AIA imaging, it is suggested that the occurred jets and their afterward dimming are responsible to trigger the sausage mode. The average electron densities of the CS over the time of the study is obtained to be log($\rm n_e$)=9.3$\rm [cm^{-3}]$. The Alfvén velocity, magnetic field, and energy flux of the observed fast kink mode over the CS are estimated to be 16.7 $\rm km/s$, 2.79 $\rm G$, 41.93 $\rm W/m^2$. Considering the magnetic flux conservation inside the CS, expanding the CS cross section, causes the magnetic field to decay with the rate of $\rm 4.95 \times 10^{-4} \, G/sec$.

description: We propose a new seesaw model in an extra-dimensional setup where only right-handed neutrinos are bulk fields. In the model, localizations of an extra-dimensional wave function and brane Majorana mass of the right-handed neutrinos can be different among each generation of the right-handed neutrinos. The setup can lead to different suppression factor dependences of effective right-handed neutrino masses and neutrino Yukawa couplings for each generation. It is shown that the resultant mass spectra of the right-handed neutrinos and neutrino Yukawa couplings are favored in models of neutrino dark matter with baryogenesis.

description: Supermassive black holes (BH) at the centres of galaxies can rapidly change their mass and spin by gas accretion and mergers. Using hydrodynamical cosmological simulations, with prescriptions for BH growth and feedback from Active Galactic Nuclei, we study how the evolution of BH mass growth is driven by gas accretion and mergers. Using a semi-analytical approach to evolve spins, we also highlight the mechanisms responsible for driving the magnitude and the direction of spins as a function of cosmic time. We find that in the high-redshift universe galaxies maintain large values of gas accretion onto BHs, which therefore is the main driver of their mass and spin evolution. Sustained accretion of cold gas at high-redshift tends to align BH spins with the angular momentum of the surrounding gas and maximise their magnitude. Conversely, at low redshift, as BHs get more massive and galaxies more gas-poor, the contribution from binary coalescences to the total BH mass growth increases, especially at the high-mass end, and tends to decrease the magnitude of spins and change their direction.

description: We isolate the two-step mechanism involving a real intermediate photon from the one-step mechanism involving a virtual photon for the trident process in a constant crossed field. The two-step process is shown to agree with an integration over polarised sub-processes. At low to moderate quantum non-linearity parameter, the one-step process is found to be suppressed. When the parameter is large, the two decay channels are comparable if the field dimensions are not much greater than the formation length.

Αναζητήθηκαν οι τρόποι που μείζονες αντιθετικές έννοιες μπορούν να συνυπάρξουν και να αναπαρασταθούν χωρικά: φυσικό-ανθρωπογενές, εσωτερικό-εξωτερικό, υφιστάμενο-μεταγενέστερο κ.ά.
Μακροσκοπικά, προτείνεται η ανάδειξη των Λουτρών ως συνδετικό στοιχείο της πρωτεύουσας του νησιού και του οικισμού των Πάλλων, με σκοπό την αποκατάσταση της ασυνέχειας του βόρειου μετώπου. Η εστιασμένη σχεδιαστική πρόταση αφορά στη σύνθεση ενός συνεκτικού συνόλου δημόσιου χαρακτήρα, ικανού να αποκαταστήσει χωρικές ή χρονικές σχέσεις που έχουν χαθεί, να δημιουργήσει νέες, και να υποδεχτεί χρήσεις πολιτισμού, έρευνας και θεραπείας. Έμφαση δίδεται, τελικά, στο προτεινόμενο κτίριο του νέου θεραπευτηρίου.

description: After the recent discovery of a 125 GeV Higgs-like particle at the Large Hadron Collider (LHC), it is crucial to examine its role in unitarizing high energy W_LW_L scattering, which may reveal its possible deviation from a Standard Model Higgs. We perform an updated study on WW scattering in the semileptonic channel at the LHC, improved by the recently developed W jet tagging method. The resultant statistical significance of a Strongly-Interacting Light Higgs (SILH) model is about 20% larger than that based on the conventionally "gold-plated" dileptonic channel, while 200% more signal events are retained. This allows the discovery of an SILH model if the signal strength is 100% (10%) of a pure Higgsless model, using about 40 (3000) fb^{-1} data at the 14 TeV LHC. Meanwhile, the excellent sensitivity to the anomalous Higgs-W boson coupling makes semileptonic WW scattering an important complement to precision measurements at the Higgs resonance.

description: Competitive interactions represent one of the driving forces behind evolution and natural selection in biological and sociological systems. For example, animals in an ecosystem may vie for food or mates; in a market economy, firms may compete over the same group of customers; sensory stimuli may compete for limited neural resources in order to enter the focus of attention. Here, we derive rules based on the spectral properties of the network governing the competitive interactions between groups of agents organized in networks. In the scenario studied here the winner of the competition, and the time needed to prevail, essentially depend on the way a given network connects to its competitors and on its internal structure. Our results allow assessing the extent to which real networks optimize the outcome of their interaction, but also provide strategies through which competing networks can improve on their situation. The proposed approach is applicable to a wide range of systems that can be modeled as networks.

description: Low-wage and low-income workers are often in precarious work situations or workplaces that endanger their health. An example of a precarious, low-wage occupation is nail salon work. Nearly 8 in 10 nail salon technicians (NSTs) are considered low-wage workers, which is a percentage that is greater than the average occupation. Nail salon technicians, who may also be referred to as manicurists and/or pedicurists, are exposed daily to products and chemicals including toluene, formaldehyde, and phthalates. Better known as the “toxic trio,” these chemicals are used as polish hardeners, thinners, and plasticizers and can cause cancer and reproductive issues especially in women. NSTs are projected to grow by 10% by 2028. With this growth and the massive influx of mostly Asian immigrant technicians to fill these nail salon positions, there should be efforts focused on health promotion and health education for these vulnerable workers. There is largely a lack of health promotion and health education literature aimed specifically at nail salon technicians, even technicians who are Asian immigrant women. This literature review aims to bring together the complex relationships between the identities of Asian immigrant nail salon technicians and their health and to provide recommendations and considerations for such health programs.

description: Because the production cross sections of gamma-rays, electrons, and positrons made in p-p collisions, $σ_{pp\rightarrow γ}$ and $σ_{pp\rightarrow {e}^\pm}$, respectively, are kinematically equivalent with respect to the parent pion-production cross section $σ_{pp\rightarrow π}$, we obtain $σ_{pp\rightarrow {e}^\pm}$ directly from the machine data on $σ_{pp\rightarrow γ}$. In Sato et al. (2012), we give explicitly $σ_{pp\rightarrow γ}$, reproducing quite well the accelerator data with LHC, namely $σ_{pp\rightarrow {e}^\pm}$ is applicable enough over the wide energy range from GeV to 20\,PeV for projectile proton energy. We dicuss in detail the relation between the cross sections, and present explicitly $σ_{pp\rightarrow {e}^\pm}$ that are valid into the PeV electron energy.

description: In the past two decades, it has been convincingly argued that magnetospheric radio emissions, of cyclotron maser origin, can occur for exoplanetary systems, similarly as solar planets, with the same periodicity as the planetary orbit. These emissions are primarily expected at low frequencies (usually below 100 MHz, c.f. Farrell et al., 1999; Zarka, 2007). The radio detection of exoplanets will considerably expand the field of comparative magnetospheric physics and star-planet plasma interactions (Hess & Zarka, 2011). We have developed a prediction code for exoplanetary radio emissions, PALANTIR: "Prediction Algorithm for star-pLANeT Interactions in Radio". This code has been developed for the construction of an up-to-date and evolutive target catalog, based on observed exoplanet physical parameters, radio emission theory, and magnetospheric physics embedded in scaling laws. It is based on, and extends, previous work by Grießmeier et al. (2007b). Using PALANTIR, we prepared an updated list of targets of interest for radio emissions. Additionally, we compare our results with previous studies conducted with similar models (Grießmeier, 2017). For the next steps, we aim at improving this code by adding new models and updating those already used.

description: Scatter radio networks have been recently proposed for environmental sens-
ing applications, e.g., water savings in agriculture. Additionally, they are
central in inventory management with radio frequency identification (RFID)
tags, as well as other Internet of Things (IoT) applications. Recent signal
processing developments in bistatic scatter radio networks have dramatically
extended their coverage; thus, knowing the location of each tag becomes
valuable information. Each scatter radio tag reflects the illuminating signal,
transmitted from multiple low-cost emitters. The received signal strength
(RSS) measurements at a single low-cost reader are usedas input in cus-
tom particle filtering (PF) algorithms, in order to localize each scatter radio
tag. Free-space, two-ray and an empirical wireless propagation large-scale
path loss models are considered, alongside a small-scale fading model and
different particle resampling techniques. Extensive simulations for a 100m x
100m grid offered root mean squared error (RMSE) as low as 1.6m. Outdoor
experimental results in a 27m x 32m grid offered 0.9m RMSE.

description: The theory of quasiparticle interference (QPI) for non-centrosymmetric (NCS) superconductors with Rashba spin-orbit coupling is developed using T-matrix theory in Born approximation. We show that qualitatively new effects in the QPI pattern originate from the Rashba spin-orbit coupling: The resulting spin coherence factors lead to a distinct difference of charge- and spin- QPI and to an induced spin anisotropy in the latter even for isotropic magnetic impurity scattering. In particular a cross - QPI appears describing the spin oscillation pattern due to nonmagnetic impurity scattering which is directly related to the Rashba vector. We apply our theory to a 2D model for the NCS heavy fermion unconventional superconductor CePt$_3$Si and discuss the new QPI features for a gap model with accidental node lines due to its composite singlet-triplet nature.
