title: Θερμική επεξεργασία καταλοίπων βωξίτη
Creators: name: Μαρακη Καλλιοπη

description: Η παρούσα διπλωματική εργασία ενασχολήθηκε πάνω σε ένα σοβαρό περιβαλλοντικό πρόβλημα της βιομηχανίας της αλουμίνας. Για την παραγωγή αλουμίνας με τη μέθοδο επεξεργασίας  Bayer παράγονται μεγάλοι όγκοι καταλοίπων βωξίτη (ερυθράς ιλύος). Οι μεγάλες ποσότητες παράγωγης ερυθράς ιλύος (80.000.000t σε παγκόσμια κλίμακα ), το μικρό μέγεθος κόκκων και το υψηλό pH (από 11 έως 13) προκαλούν σημαντικά περιβαλλοντικά προβλήματα στην περιοχή απόθεσής της. Λόγω αυτών των ιδιαίτερων χαρακτηριστικών της ερυθράς ιλύος γίνονται συνεχώς ερευνητικές μελέτες για την εύρεση τρόπων αξιοποίησής της.
Καθώς η ερυθρά ιλύς αποτελείται από μεταλλικά οξείδια, η παρούσα εργασία αποσκοπεί στον εμπλουτισμό των καταλοίπων του βωξίτη σε περοβσκίτη (CaTiO3) . Ο τρόπος εμπλουτισμού που επιλέχτηκε ήταν με προσθήκη ποσότητας άνθρακα (5%C και 20%C) και θέρμανση του υλικού σε διαφορές θερμοκρασίες που κυμαίνονται από 400οC έως 1200οC σε οξειδωτικό περιβάλλον και σε θερμοκρασίες από 400οC έως 1000οC σε αναγωγικό περιβάλλον. Στη συνέχεια, μελετήθηκε η εύρεση ενός οικονομικού τρόπου εμπλουτισμού του οξειδίου του τιτανίου (TiO2)  που εμπεριέχεται στο ορυκτό περοβσκίτη. Ο τρόπος εμπλουτισμού του οξειδίου του τιτανίου που επιλέχτηκε ήταν ο υγρός μαγνητικός διαχωρισμός διαφορετικών εντάσεων ηλεκτρικού ρεύματος. Σε κάθε διαδικασία εμπλουτισμού του κάθε δείγματος  πραγματοποιήθηκαν ορυκτολογικές και  χημικές αναλύσεις.

description: This work is devoted to analyze the energy of the Universe in the context of f(T) theories. Such theories are the analogous counterpart of the well known f(R) theories that, however, uses torsion instead of curvature. We obtain a general expression for the gravitational energy-momentum vector in this framework. Using the hypothesis of the isotropy of spacetime, we find the energy of the Universe and compare it with the energy obtained in the realm of teleparallelism equivalent to general relativity (TEGR).

description: Abstract: Introduction: As the demand for rehabilitation in orthopaedics increases, so too has the development in advanced rehabilitation technology. However, to date, there are no review papers outlining the broad scope of advanced rehabilitation technology used within the orthopaedic population. The aim of this study is to identify, describe and summarise the evidence for efficacy for all advanced rehabilitation technologies applicable to orthopaedic practice. Methods: The relevant literature describing the use of advanced rehabilitation technology in orthopaedics was identified from appropriate electronic databases (PubMed and EMBASE) and a narrative review undertaken. Results: Advanced rehabilitation technologies were classified into two groups: hospital-based and home-based rehabilitation. In the hospital-based technology group, we describe the use of continuous passive motion and robotic devices (after spinal cord injury) and their effect on improving clinical outcomes. We also report on the use of electromagnetic sensor technology for measuring kinematics of upper and lower limbs during rehabilitation. In the home-based technology group, we describe the use of inertial sensors, smartphones, software applications and commercial game hardware that are relatively inexpensive, user-friendly and widely available. We outline the evidence for videoconferencing for promoting knowledge and motivation for rehabilitation as well as the emerging role of virtual reality. Conclusions: The use of advanced rehabilitation technology in orthopaedics is promising and evidence for its efficacy is generally supportive.

Cooperative cataloging

description: BIBCO is one of four programs in the PCC. This article summarizes the development of BIBCO and how its cataloging training program was strikingly different from the other three programs: NACO, CONSER and SACO. BIBCO grew out of the 1990–1991 recession which created widespread anxiety over the cost of original cataloging. BIBCO attempted to reduce the cost without sacrificing quality and increase record production through the use of core records. The early training emphasized the value of cooperation. PCC’s strength in this area is seen today in its partnerships and leadership in metadata initiatives such as linked data.
Shock waves in dispersive Eulerian fluids

description: The long time behavior of an initial step resulting in a dispersive shock wave (DSW) for the one-dimensional isentropic Euler equations regularized by generic, third order dispersion is considered by use of Whitham averaging. Under modest assumptions, the jump conditions (DSW locus and speeds) for admissible, weak DSWs are characterized and found to depend only upon the sign of dispersion (convex or concave) and a general pressure law. Two mechanisms leading to the breakdown of this simple wave DSW theory for sufficiently large jumps are identified: a change in the sign of dispersion, leading to gradient catastrophe in the modulation equations, and the loss of genuine nonlinearity in the modulation equations. Large amplitude DSWs are constructed for several particular dispersive fluids with differing pressure laws modeled by the generalized nonlinear Schrodinger equation. These include superfluids (Bose-Einstein condensates and ultracold Fermions) and "optical fluids". Estimates of breaking times for smooth initial data and the long time behavior of the shock tube problem are presented. Numerical simulations compare favorably with the asymptotic results in the weak to moderate amplitude regimes. Deviations in the large amplitude regime are identified with breakdown of the simple wave DSW theory.

description: Abstract: One-in-two people suffering from mental health problems develop such distress before or during adolescence. Research has shown that distress can predict itself well over time. Yet, little is known about how well resilience factors (RFs), i.e. those factors that decrease mental health problems, predict subsequent distress. Therefore, we investigated which RFs are the best indicators for subsequent distress and with what accuracy RFs predict subsequent distress. We examined three interpersonal (e.g. friendships) and seven intrapersonal RFs (e.g. self-esteem) and distress in 1130 adolescents, at age 14 and 17. We estimated the RFs and a continuous distress-index using factor analyses, and ordinal distress-classes using factor mixture models. We then examined how well age-14 RFs and age-14 distress predict age-17 distress, using stepwise linear regressions, relative importance analyses, as well as ordinal and linear prediction models. Low brooding, low negative and high positive self-esteem RFs were the most important indicators for age-17 distress. RFs and age-14 distress predicted age-17 distress similarly. The accuracy was acceptable for ordinal (low/moderate/high age-17 distress-classes: 62–64%), but low for linear models (37–41%). Crucially, the accuracy remained similar when only self-esteem and brooding RFs were used instead of all ten RFs (ordinal = 62%; linear = 37%); correctly predicting for about two-in-three adolescents whether they have low, moderate or high distress 3 years later. RFs, and particularly brooding and self-esteem, seem to predict subsequent distress similarly well as distress can predict itself. As assessing brooding and self-esteem can be strength-focussed and is time-efficient, those RFs may be promising for risk-detection and translational intervention research.

Για τον έλεγχο της ευστάθειας, χρησιμοποιούνται οι ντετερμινιστικοί μέθοδοι υπολογισμού του συντελεστή ασφάλειας καθώς και οι πιθανοκρατικές μέθοδοι για την περιγραφή της διακύμανσης αυτού, αν ληφθούν υπόψη οι αβεβαιότητες που σχετίζονται με τον σχεδιασμό του πρανούς, τον υδροφόρο ορίζοντα και τις ιδιότητες της ασυνέχειας. Η κατάρρευση βραχωδών πρανών αποτελεί ένα συχνό φαινόμενο και οι επιπτώσεις που μπορούν να προκληθούν μπορεί να είναι σημαντικές για τα πρανή, τη λειτουργία υπαίθριων εκμεταλλεύσεων αλλά και για τα πρανή σε δημόσιους δρόμους, κατοικημένες περιοχές και εν γένει σε περιοχές με ανθρώπινες δραστηριότητες. Συνεπώς κρίνεται απαραίτητη η εξέταση της ευστάθειας τέτοιων βραχωδών πρανών σε ασυνεχείς βραχόμαζες. Αρχικά, στα δύο πρώτα κεφάλαια, περιγράφονται βασικές εισαγωγικές έννοιες σχετικές με την ανάλυση της ευστάθειας ενός πρανούς, οι παράγοντες που συμβάλλουν σε αυτή και παρουσιάζονται τα κριτήρια αστοχίας τα οποία προσομοιάζουν τα στιγμιαία εντατικά πεδία σε ένα σχηματισμό, προσδιορίζοντας την στιγμή της αστοχίας. Επιπρόσθετα, στα επόμενα δύο κεφάλαια (τρίτο και τέταρτο), αναλύονται τα είδη των μηχανισμών αστοχίας που μπορούν να προκύψουν ανάλογα με τα χαρακτηριστικά της βραχόμαζας, αναφέρεται η συμβολή των στερεοδιαγραμμάτων στην ευστάθεια και παρουσιάζεται ένα μοντέλο αστοχίας πρανούς με τη μορφή κινηματικής αλυσίδας δύο άκαμπτων ογκοτεμαχίων πετρώματος που συντελούν σε μη-επίπεδη επιφάνεια αστοχίας του πρανούς. Τέλος, στα δύο τελευταία κεφάλαια, παρουσιάζεται το υπολογιστικό μοντέλο της ανάλυσης ευστάθειας, με γραμμικά και μη-γραμμικά κριτήρια, χρησιμοποιώντας τις ντετερμινιστικές μεθόδους υπολογισμού του συντελεστή ασφάλειας καθώς και την χρήση των πιθανοκρατικών μεθόδων.

description: In this paper we investigate gravitational perturbations of a regular black hole, particularly Bardeen solution. Such system is solution of Einstein equations that do not have a singularity at the origin of the radial symmetry. However it still have events horizons depending on the values of the characteristic parameters of the solution. When a black hole is perturbed, it oscillates. It gives rise to damped vibrating modes which are known as quasinormal modes. It is calculated the quasinormal frequencies of a regular black hole using the third order WKB approximation for gravitational perturbations. The results are presented in tables I, II and III.

description: Companies and healthcare providers are developing and implementing new applications of medical artificial intelligence, including the artificial intelligence sub-type of medical machine learning (MML). MML is based on the application of machine learning (ML) algorithms to automatically identify patterns and act on medical data to guide clinical decisions. MML poses challenges and raises important questions, including (1) How will regulators evaluate MML-based medical devices to ensure their safety and effectiveness? and (2) What additional MML considerations should be taken into account in the international context? To address these questions, we analyze the current regulatory approaches to MML in the USA and Europe. We then examine international perspectives and broader implications, discussing considerations such as data privacy, exportation, explanation, training set bias, contextual bias, and trade secrecy.

description: Στην παρούσα διπλωματική εργασία στόχος είναι η βελτίωση των μηχανικών ιδιοτήτων κεραμικών ικριωμάτων από υδροξυαπατίτη. Για την ενίσχυση χρησιμοποιήθηκαν πρόσθετα υλικά όπως το πυριτικό νάτριο (Na2O.SiO2), στο πρώτο μέρος της εργασίας, ενώ στο δεύτερο μέρος χρησιμοποιήθηκαν το guar gum, ένας πυκνωτικός παράγοντας καθώς και βρώσιμη ζελατίνη. Κατά την παρασκευή χρησιμοποιήθηκαν διάφορες αναλογίες διασπορέα, συνδέτη, υδροξυαπατίτη και των ενισχυτικών υλικών, με σκοπό τον βέλτιστο προσδιορισμό των συνθηκών παρασκευής. Η μέθοδος που ακολουθήθηκε στο εργαστήριο για την δημιουργία των ικριωμάτων είναι η μέθοδος της χύτευσης μετά από φυγοκέντρηση. Η χύτευση των μιγμάτων σε καλούπια σιλικόνης και η ομαλή ξήρανσή τους σε θερμοκρασία περιβάλλοντος πριν την έψηση, οδήγησε σε συμπαγή κεραμικά ικριώματα. Ο συνδυασμός των υψηλών θερμοκρασιών (1260 οC) και της προσθήκης του πυριτικού νατρίου οδήγησε στην ενίσχυση των μηχανικών ιδιοτήτων των κεραμικών.

The scatterings of a heavy quark with the hard medium particles give rise to Debye screened QCD force and drag force and its fluctuation. We present a unified quantum description of these in-medium QCD forces at high temperature in the leading-order perturbation on the basis of the influence functional formalism.

description: Geomagnetic storms play a critical role in space weather physics with the potential for far reaching economic impacts including power grid outages, air traffic rerouting, satellite damage and GPS disruption. The LFM-MIX is a state-of-the-art coupled magnetospheric-ionospheric model capable of simulating geomagnetic storms. Imbedded in this model are physical equations for turning the magnetohydrodynamic state parameters into energy and flux of electrons entering the ionosphere, involving a set of input parameters. The exact values of these input parameters in the model are unknown, and we seek to quantify the uncertainty about these parameters when model output is compared to observations. The model is available at different fidelities: a lower fidelity which is faster to run, and a higher fidelity but more computationally intense version. Model output and observational data are large spatiotemporal systems; the traditional design and analysis of computer experiments is unable to cope with such large data sets that involve multiple fidelities of model output. We develop an approach to this inverse problem for large spatiotemporal data sets that incorporates two different versions of the physical model. After an initial design, we propose a sequential design based on expected improvement. For the LFM-MIX, the additional run suggested by expected improvement diminishes posterior uncertainty by ruling out a posterior mode and shrinking the width of the posterior distribution. We also illustrate our approach using the Lorenz `96 system of equations for a simplified atmosphere, using known input parameters. For the Lorenz `96 system, after performing sequential runs based on expected improvement, the posterior mode converges to the true value and the posterior variability is reduced.

Eu–Us Privacy Shield

description: International health research increasingly depends on collaboration and combination using medical data to advance treatment and drug discovery. The European Union (EU), through its General Data Protection Regulation, has tightened the rules for sharing data across borders to protect individual privacy. These new rules threaten cooperation between the EU and the USA, the two largest public funders of biomedical research. This article analyzes the primary pathway for sharing research data with the USA, the US-EU Privacy Shield, and argues that the Shield is ill-suited to support complex health studies. Its legitimacy is in question under both EU and US law, and its terms are too restrictive for the variety of exchanges underlying research, treatment, and care. As an alternative, we propose that the USA seek an additional sector-based adequacy determination based on the existing US health privacy law, the Health Insurance Portability and Accountability Act. A sector-specific approach to adequacy for health would avoid many of the most contentious issues that divide the USA and EU on data protection. It could also serve as a model for other third-party jurisdictions and facilitate international harmonization of health research practices.

User interfaces (Computer systems)--Testing

description: In 2017, seven members of the Archive-It Mid-Atlantic Users Group (AITMA) conducted a study of fourteen participants representative of their stakeholder populations to assess the usability of Archive-It, a web archiving subscription service of the Internet Archive. While Archive-It is the most widely used tool for web archiving, little is known about how users interact with the service. This study investigated what users expect from web archives, a distinct form of archival materials. End-user participants executed four search tasks using the public Archive-It interface and the Wayback Machine to access archived information on websites from the facilitators’ own harvested collections and provided feedback about their experiences. The tasks were designed to have straightforward outcomes (completed or not completed), and the facilitators took notes on the participants’ behavior and commentary during the sessions. Overall, participants reported mildly positive impressions of the Archive-It public user interface based on their sessions. The study identified several key areas of improvement for the Archive-It service pertaining to metadata options, terminology display, indexing of dates, and the site’s search box.

description: The Aharonov--Bohm effect is considered as a scattering event with nonrelativistic charged particles of the wavelength which is less than the transverse size of an impenetrable magnetic vortex. The quasiclassical WKB method is shown to be efficient in solving this scattering problem. We find that the scattering cross section consists of two terms, one describing the classical phenomenon of elastic reflection and another one describing the quantum phenomenon of diffraction; the Aharonov--Bohm effect is manifested as a fringe shift in the diffraction pattern. Both the classical and the quantum phenomena are independent of the choice of a boundary condition at the vortex edge, providing that probability is conserved. We show that a propagation of charged particles can be controlled by altering the flux of a magnetic vortex placed on their way.

description: Статья посвящена проблеме современного загрязнения атмосферного воздуха города Великий Новгород выхлопными газами автомобилей. На основании оригинальной методики с применением дистанционных методов наблюдения за ситуацией на дорогах и специально разработанной математической модели авторы оценивают вклад автотранспорта в уровень загрязнения воздушного бассейна г. В. Новгород на самых оживлённых перекрёстках. По результатам исследования сделан вывод, что выбросы от транспортных
средств не создают превышение ПДК по углекислому газу, также выделяются значительные временные колебания в мощности источника загрязнения, полностью коррелирующие с напряжённостью транспортного потока. Предложены мероприятия, направленные на снижение уровня загрязнения городской среды, которые могли бы быть как реализованы на уровне муниципалитета, так и предприняты каждым жителем города.

description: Jacobson's thermodynamic derivation of the Einstein equations was originally applied only to local Rindler horizons. But at least some parts of that construction can usefully be extended to give meaningful results for arbitrary bifurcate null surfaces. As presaged in Jacobson's original article, this more general construction sharply brings into focus the questions: Is entropy objectively "real"? Or is entropy in some sense subjective and observer-dependent? These innocent questions open a Pandora's box of often inconclusive debate. A consensus opinion, though certainly not universally held, seems to be that Clausius entropy (thermodynamic entropy, defined via a Clausius relation dS = dQ/T) should be objectively real, but that the ontological status of statistical entropy (Shannon or von Neumann entropy) is much more ambiguous, and much more likely to be observer-dependent. This question is particularly pressing when it comes to understanding Bekenstein entropy (black hole entropy). To perhaps further add to the confusion, we shall argue that even the Clausius entropy can often be observer-dependent. In the current article we shall conclusively demonstrate that one can meaningfully assign a notion of Clausius entropy to arbitrary bifurcate null surfaces --- effectively defining a "virtual Clausius entropy" for arbitrary "virtual (local) causal horizons". As an application, we see that we can implement a version of the generalized second law (GSL) for this virtual Clausius entropy. This version of GSL can be related to certain (nonstandard) integral variants of the null energy condition (NEC). Because the concepts involved are rather subtle, we take some effort in being careful and explicit in developing our framework. In future work we will apply this construction to generalize Jacobson's derivation of the Einstein equations.

description: Tropical cyclone intensification processes are explored in six high-resolution climate models. The analysis framework employs process-oriented diagnostics that focus on how convection, moisture, clouds, and related processes are coupled. These diagnostics include budgets of column moist static energy and the spatial variance of column moist static energy, where the column integral is performed between fixed pressure levels. The latter allows for the quantification of the different feedback processes responsible for the amplification of moist static energy anomalies associated with the organization of convection and cyclone spinup, including surface flux feedbacks and cloud-radiative feedbacks. Tropical cyclones (TCs) are tracked in the climate model simulations and the analysis is applied along the individual tracks and composited over many TCs. Two methods of compositing are employed: a composite over all TC snapshots in a given intensity range, and a composite over all TC snapshots at the same stage in the TC life cycle (same time relative to the time of lifetime maximum intensity for each storm). The radiative feedback contributes to TC development in all models, especially in storms of weaker intensity or earlier stages of development. Notably, the surface flux feedback is stronger in models that simulate more intense TCs. This indicates that the representation of the interaction between spatially varying surface fluxes and the developing TC is responsible for at least part of the intermodel spread in TC simulation.

Extended Lagrangian Born-Oppenheimer molecular dynamics in the limit of vanishing self-consistent field optimization

description: We present an efficient general approach to first principles molecular dynamics simulations based on extended Lagrangian Born-Oppenheimer molecular dynamics in the limit of vanishing self-consistent field optimization. The reduction of the optimization requirement reduces the computational cost to a minimum, but without causing any significant loss of accuracy or longterm energy drift. The optimization-free first principles molecular dynamics requires only one single diagonalization per time step and yields trajectories at the same level of accuracy as "exact", fully converged, Born-Oppenheimer molecular dynamics simulations. The optimization-free limit of extended Lagrangian Born-Oppenheimer molecular dynamics therefore represents an ideal starting point for a robust and efficient formulation of a new generation first principles quantum mechanical molecular dynamics simulation schemes.

Propagation of measurement error in opinion dynamics models: The case of the Deffuant model

description: Opinion dynamics models have an enormous potential for studying current phenomena such as vaccine hesitancy or diffusion of fake news. Unfortunately, to date, most of the models have little to no empirical validation. One major problem in testing these models against real-world data relates to the difficulties in measuring opinions in ways that map directly to representations in models. Indeed, measuring opinions is a complex process and presents more types of measurement error than just classical random noise. Thus, it is crucial to know how these different error types may affect the model’s predictions. In this work, we analyze this relationship in the Deffuant model as an example. Starting from the psychometrics literature, we first discuss how opinion measurements are affected by three types of errors: random noise, binning, and distortions (i.e. uneven intervals between scale points). While the first two are known to most of the scientific community, the third one is mostly unknown outside psychometrics. Because of that, we highlight the nature and peculiarities of each of these measurement errors. By simulating these types of error, we show that the Deffuant model is robust to binning but not to noise and distortions. Indeed, if a scale has 4 or more points (like most self-report scales), binning has almost no effect on the final predictions. However, prediction error increases almost linearly with random noise, up to a maximum error of 40%. After reaching this value, increasing the amount of noise does not worsen the prediction. Distortions are most problematic, reaching a maximum prediction error of 80%. Error propagation is already established in other fields, such as statistics and engineering. We believe its application in opinion dynamics will contribute to the expansion and development of this field. Indeed, as we show here, it allows researchers to test models’ reliability and prediction quality even before testing the model against real world data

description: Capsular polysaccharides enable clinically important clones of Klebsiella pneumoniae to cause severe systemic infections in susceptible hosts. Phage-encoded capsule depolymerases have the potential to provide an alternative treatment paradigm in patients when multiple drug resistance has eroded the efficacy of conventional antibiotic chemotherapy. An investigation of 164 K. pneumoniae from intensive care patients in Thailand revealed a large number of distinct K types in low abundance but four (K2, K51, K1, K10) with a frequency of at least 5%. To identify depolymerases with the capacity to degrade capsules associated with these common K-types, 62 lytic phage were isolated from Thai hospital sewage water using K1, K2 and K51 isolates as hosts; phage plaques, without exception, displayed halos indicative of the presence of capsule-degrading enzymes. Phage genomes ranged in size from 41-348 kb with between 50 and 535 predicted coding sequences (CDSs). Using a custom phage protein database we were successful in applying annotation to 30 - 70% (mean = 58%) of these CDSs. The largest genomes, of so-called jumbo phage, carried multiple tRNAs as well as CRISPR repeat and spacer sequences. One of the smaller phage genomes was found to contain a putative Cas type 1E gene, indicating a history of host DNA acquisition in these obligate lytic phage. Whole-genome sequencing (WGS) indicated that some phage displayed an extended host range due to the presence of multiple depolymerase genes; in total, 42 candidate depolymerase genes were identified with up to eight in a single genome. Seven distinct virions were selected for further investigation on the basis of host range, phage morphology and WGS. Candidate genes for K1, K2 and K51 depolymerases were expressed and purified as his6-tagged soluble protein and enzymatic activity demonstrated against K. pneumoniae capsular polysaccharides by gel electrophoresis and Anton-Paar rolling ball viscometry. Depolymerases completely removed the capsule in K-type-specific fashion from K. pneumoniae cells. We conclude that broad-host range phage carry multiple enzymes, each with the capacity to degrade a single K-type, and any future use of these enzymes as therapeutic agents will require enzyme cocktails for utility against a range of K. pneumoniae infections.

description: The effective crystal field in multi-orbital correlated materials can be either enhanced or reduced by electronic correlations with crucial consequences for the topology of the Fermi surface and, hence, on the physical properties of these systems. In this respect, recent local density approximation (LDA) plus dynamical mean-field theory (DMFT) studies of Ni-based heterostructure have shown contradicting results, depending on whether the less correlated $p$-orbitals are included or not. We investigate the origin of this problem and identify the key parameters controlling the Fermi surface properties of these systems. Without the $p$-orbitals the model is quarter filled, while the $d$ manifold moves rapidly towards half-filling when the $p$-orbitals are included. This implies that the local Hund's exchange, while rather unimportant for the former case, can play a predominant role in controlling the orbital polarization for the extended basis-set by favoring the formation of a larger local magnetic moment.

description: Non-interferometric approaches to quantitative phase imaging could enable its application in low-cost, miniaturised settings such as capsule endoscopy. We present two possible architectures and both analyse and mitigate the effect of sensor misalignment on phase imaging performance. This is a crucial step towards determining the feasibility of implementing phase imaging in a capsule device. First, we investigate a design based on a folded 4f correlator, both in simulation and experimentally. We demonstrate a novel technique for identifying and compensating for axial misalignment and explore the limits of the approach. Next, we explore the implications of axial and transverse misalignment, and of manufacturing variations on the performance of a phase plate-based architecture, identifying a clear trade-off between phase plate resolution and algorithm convergence time. We conclude that while the phase plate architecture is more robust to misalignment, both architectures merit further development with the goal of realising a low-cost, compact system for applying phase imaging in capsule endoscopy.
