A System for the efficient automated analysis of reconstructed double-pulsed holograms
Creators: name: Zhao, Zhijun
Publisher: name: University of British Columbia
Year: 2008

description: Double-pulsed holograms of particles in a flow form the basis of Holographic Particle Image Velocimetry (HPIV), which is becoming widely used for the measurement of three-dimensional velocity fields. The major deficiency of HPIV is that the double-pulsed holograms must be surveyed by a human operator, at a considerable cost in time and effort, to determine the location of objects within the holographic volume. A system that automatically and efficiently analyzes double-pulsed holograms of microbubbles in flowing water has been developed. The system employs a three-part algorithm: 1.Holograms of microbubbles are scanned in the holographic (x-y) plane using acomputer-controlled positioning table. Microbubbles within the scanned regionare detected by a CCD-based fast object detection system. On detection of a probable bubble signal, the CCD board signals the computer to stop scanning. 2.Bubble images thus detected are focussed (in the z-direction) using a software-based auto focussing technique. 3. In-focus bubble images are analyzed by a simple set of image analysis techniques, including edge detection and patch correlation. The output of this algorithm is the size, and displacement between the two laser pulses, of microbubbles in the water flow. Large numbers of experiments were conducted using this algorithm. On the basis of these experiments it is concluded that scanning the large empty regions ofspace in a hologram to identify the widely separated microbubbles (step 1 above) can be done at almost the human rate. In contrast, the second part of the algorithm — autofocussing of bubble images with the present hardware — requires more time than does a human operator. The third part of the algorithm, involving automated bubble image analysis, can be carried out at very nearly the human rate.

description: Pecci-Quinn (PQ) symmetry breaking by perturbative dynamics would suffer from a hierarchy problem, just like the electroweak symmetry breaking in the standard model. The dynamics of the axion, associated with the PQ symmetry breaking, would also involve a triviality problem. We provide a paradigm to resolve those two problems potentially existing in the PQ symmetry breaking scenario, with keeping successful axion relaxation for the QCD strong CP phase. The proposed theory includes an axicolor dynamics with the axicolored fermions partially gauged by the QCD color, and is shown to be governed by an asymptotically safe (AS) fixed point: quantum scale invariance is built. The AS axicolor is actually a ``walking" dynamics, which dynamically breaks a PQ symmetry, a part of the chiral symmetry carried by the axicolored fermions. The PQ scale generation is then triggered by the nonperturbative dimensional transmutation in the ``walking" dynamics. A composite axion emerges as the assosiated Nambu-Goldstone boson. That is, no hierarchy or triviality problem is present there. The composite axion can potentially be light due to the characteristic feature of the AS axicolor (``walking" axicolor), becomes the QCD axion in the anti-Veneziano limit, and gets heavier by the subleading correction. The composite axion relaxes the QCD theta parameter, involving heavier relaxation partners such as axicolored pseudoscalar mesons, and the ultraviolet correction to the relaxation mechanism is protected by the established (near) scale invariance during the ``walking" regime.

description: Η ελληνική γλώσσα έχει ένα πολύ πλούσιο λεξιλόγιο και εξελίσσεται ταχέως τους τελευταίους δύο αιώνες. Αυτή η μελέτη επικεντρώνεται στην τελευταία μορφή της και προσπαθεί να ερευνήσει για οποιαδήποτε μετατόπιση στην σημασία των λέξεων που μπορεί να έχει συμβεί κατά τη διάρκεια αυτής της περιόδου. Αυτό επιτυγχάνεται με τη συλλογή μεγάλων ποσοτήτων ψηφιοποιημένων λογοτεχνικών βιβλίων, την επεξεργασία και την ανάλυση τους χρησιμοποιώντας εργαλεία επεξεργασίας φυσικής γλώσσας από την αιχμή της τεχνολογίας που είναι ικανά να μαθαίνουν αναπαραστάσεις της ανθρώπινης γλώσσας. Συγκεκριμένα διαμορφώνουμε μοντέλα εκμάθησης εννοιών των λέξεων με τη βοήθεια των διανυσμάτων που είναι γνωστά ως word embeddings με τη χρησιμοποίηση της βιβλιοθήκης fastText. Έπειτα τα αξιολογούμε και προσπαθούμε να ανιχνεύσουμε μετατοπίσεις στην σημασία των λέξεων, πραγματοποιώντας σύγκριση μέσω της απόστασης συνημιτόνου (cosine distance) των διανυσμάτων της ίδιας λέξης μεταξύ διαφορετικών χρονολογικών περιόδων
description: The Greek language has a very rich vocabulary and has been evolving rapidly through the last two centuries. This study focuses on its latest form and tries to look for any word meaning shifts that may have occurred during that period. It achieves that by gathering large amounts of digitized literature books, parsing and analyzing them using state-of-the-art natural language processing tools that are capable of learning representations of human language. Specifically we learn models of word representation with the help of word embeddings and by leveraging the fastText library. Afterwards we evaluate them and try to detect shifts in the meaning of words, by performing comparisons using the cosine distance of the vectors (embeddings) of the same word between different time periods

Ανέδειξε το περιεχόμενο της αρετής και υπήρξε ο εμπνευστής της διαλεκτικής, μαιευτικής μεθόδου, όλη του η διδασκαλία επικεντρώθηκε στην επίμονη αναζήτηση της αλήθειας. Η Απολογία του μάλιστα ανέδυσε τις φιλοσοφικές του απόψεις για τη λογική της δικαιοσύνης με τίμημα τη ζωή του. Βασικό του μέλημα ήταν ο άνθρωπος να μένει πιστός στις εντολές των νόμων, διότι μόνον έτσι η πολιτεία θα διέπεται από σταθερότητα και ασφάλεια. Τόνισε ότι καμία αρετή δεν έχει αξία, όταν δεν συμπορεύεται του πνεύματος της δικαιοσύνης
description: The aim of the present thesis was the study of the personality of Socrates, a sample of a superior ethical personality, which left its own long lasting mark, he was engaged himself with the importance of ethical dilemmas in human life and led to the formation of the human’s spiritual being through their contribution. He highlighted the exact meaning of virtue and he was the inspirer of the dialectic, the Socratic method, while he focused the whole of his teaching on the persistent searching of the truth. His Apology helped his philosophical views about the subject of justice to emerge, even at the cost of his own life. His main concern was that a person should be loyal to the law’s orders and as a result the state will be stable and safe. He declared that no virtue is valuable when it is not accompanied with the spirit of justice

description: The present study is an attempt to approximate empirical experiences and their association with Christian education. The ultimate goal is to highlight the contribution of empirical experiences to the development of Christian education for individuals. The role of experiences is crucial for people's lives and for the further development of their Christian consciousness. Empirical experiences haunt individuals throughout their lives. The family environment can contribute to the creation of appropriate empirical experiences for the cultivation of Christian education. Then, the school as a learning vehicle through the teaching methods it utilizes can promote Christian experiences for children. Furthermore, the church as a conduit of Christian tradition can contribute to the Christian education of young people by providing the necessary Christian experiences. Finally, experiential experiences play an important role in the development of the Christian education of individuals by identifying the elements of their identity

description: Gruner put forward a single particle model of charge-density wave, which is a typical nonlinear differential equation, and also a mathematical model of pendulum. This Letter analyzes the solution of equation by the rotated vector fields theory, providing the relation between the applied field E and the periodic solution, and the conclusion that the critical value of E for the periodic solution is fixed in the over-damped situation. With these conclusions, it derives the formulae of nonlinear conductivity, narrow-band noise, which are consistent with the empirical ones given by Fleming.

From Peierls brackets to a generalized Moyal bracket for type-I gauge theories

description: In the space-of-histories approach to gauge fields and their quantization, the Maxwell, Yang--Mills and gravitational field are well known to share the property of being type-I theories, i.e. Lie brackets of the vector fields which leave the action functional invariant are linear combinations of such vector fields, with coefficients of linear combination given by structure constants. The corresponding gauge-field operator in the functional integral for the in-out amplitude is an invertible second-order differential operator. For such an operator, we consider advanced and retarded Green functions giving rise to a Peierls bracket among group-invariant functionals. Our Peierls bracket is a Poisson bracket on the space of all group-invariant functionals in two cases only: either the gauge-fixing is arbitrary but the gauge fields lie on the dynamical sub-space; or the gauge-fixing is a linear functional of gauge fields, which are generic points of the space of histories. In both cases, the resulting Peierls bracket is proved to be gauge-invariant by exploiting the manifestly covariant formalism. Moreover, on quantization, a gauge-invariant Moyal bracket is defined that reduces to i hbar times the Peierls bracket to lowest order in hbar.

description: Spontaneous C4-symmetry breaking phases are ubiquitous in layered quantum materials, and often compete with other phases such as superconductivity. Preferential suppression of the symmetry broken phases by light has been used to explain non-equilibrium light induced superconductivity, metallicity, and the creation of metastable states. Key to understanding how these phases emerge is understanding how C4 symmetry is restored. A leading approach is based on time-dependent Ginzburg-Landau theory, which explains the coherence response seen in many systems. However, we show that, for the case of the single layered manganite La0.5Sr1.5MnO4, the theory fails. Instead, we find an ultrafast inhomogeneous disordering transition in which the mean-field order parameter no longer reflects the atomic-scale state of the system. Our results suggest that disorder may be common to light-induced phase transitions, and methods beyond the mean-field are necessary for understanding and manipulating photoinduced phases.

description: We present evidence for globular cluster stellar debris in a dwarf galaxy system (Sagittarius: Sgr) based on an analysis of high-resolution \textit{H}-band spectra from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey. We add [N/Fe], [Ti/Fe], and [Ni/Fe] abundance ratios to the existing sample of potential members of M~54; this is the first time that [N/Fe] abundances are derived for a large number of stars in M~54. Our study reveals the existence of a significant population of nitrogen- (with a large spread, $\gtrsim1$ dex) and aluminum-enriched stars with moderate Mg depletion in the core of the M~54$+$Sagittarius system, which shares the light element anomalies characteristic of second-generation globular cluster stars (GCs), thus tracing the typical phenomenon of multiple stellar populations seen in other Galactic GCs at similar metallicity, confirming earlier results based on the Na-O anti-correlation. We further show that most of the stars in M~54 exhibit different chemical - patterns evidently not present in Sgr field stars. Furthermore, we report the serendipitous discovery of a nitrogen-enhanced extra-tidal star with GC second-generation-like chemical patterns for which both chemical and kinematic evidence is commensurate with the hypothesis that the star has been ejected from M~54. Our findings support the existence of chemical anomalies associated with likely tidally shredded GCs in dwarf galaxies in the Local Group and motivate future searches for such bonafide stars along other known Milky Way streams.

The effect of bandsaw stresses of blade stiffness and cutting accuracy
Creators: name: Taylor, John
Publisher: name: University of British Columbia
Year: 2008

description: This thesis consists of an experimentally based study of the effect of bandsaw stresses on blade stiffness and cutting accuracy for the bandmills used for primary breakdown in North American sawmills. The effect of bandsaw roll-tensioning and bandmill axial forces on the stresses in the blade, on the interaction of the blade with the bandmill and on the stiffness and cutting accuracy of the sawblade are examined. The stresses due to roll-tensioning are measured and empirical relationships developed that relate the rolling load to the stresses induced. Investigations into effect of roll-tensioning on the torsional frequency and lateral stiffness of the sawblade show that rolling in the centre 60% of the sawblade will increase blade stiffness while rolling outside this region will decrease it. The optimum rolling location was shown to be the sawblade centre-line. The stresses in the blade due to the interaction of the blade and wheel were analyzed and a model was developed that successfully predicted the effects of roll-tensioning and overhang on the tracking stability of the sawblade. Experiments were conducted to determine how the stresses, frequency and stiffness of the sawblade relate to its cutting accuracy. The experiments indicate that cutting accuracy is strongly related to the lateral edge stiffness of the sawblade and that improved cutting accuracy can be obtained by confining the roll-tensioning to be close to the blade centre-line.

The first step is to understand whether a model galaxy without Dark Matter can sustain the feedback of the ongoing star formation. We present tests of the evolution of models in which star formation efficiency, temperature threshold, initial distribution of gas and infall are varied. We conclude that it is feasible to keep a fraction of gas bound for several hundreds of Myr and that the development of galactic winds does not necessarily stop continuous star formation.

description: The key procedure of haze image translation through adversarial training lies in the disentanglement between the feature only involved in haze synthesis, i.e.style feature, and the feature representing the invariant semantic content, i.e. content feature. Previous methods separate content feature apart by utilizing it to classify haze image during the training process. However, in this paper we recognize the incompleteness of the content-style disentanglement in such technical routine. The flawed style feature entangled with content information inevitably leads the ill-rendering of the haze images. To address, we propose a self-supervised style regression via stochastic linear interpolation to reduce the content information in style feature. The ablative experiments demonstrate the disentangling completeness and its superiority in level-aware haze image synthesis. Moreover, the generated haze data are applied in the testing generalization of vehicle detectors. Further study between haze-level and detection performance shows that haze has obvious impact on the generalization of the vehicle detectors and such performance degrading level is linearly correlated to the haze-level, which, in turn, validates the effectiveness of the proposed method.

description: Diffusive Radiation is a new type of radiation predicted to occur in randomly inhomogeneous media due to the multiple scattering of pseudophotons. This theoretical effect is now observed experimentally. The radiation is generated by the passage of electrons of energy 200KeV-2.2MeV through a random stack of films in the visible light region. The radiation intensity increases resonantly provided the Cherenkov condition is satisfied for the average dielectric constant of the medium. The observed angular dependence and electron resonance energy are in agreement with the theoretical predictions. These observations open a road to application of diffusive radiation in particle detection, astrophysics, soft X-ray generation and etc.. `

From the maximum likelihood ratio statistic, we obtain a coherent statistic which is slightly different from and generally better than what we obtained in our previous work. In the special case when the cross spectrum of two detectors normalized by the power spectrum density is constant, the new statistic agrees with the old one. The quantitative difference of the detection probability for a given false alarm rate is also evaluated in a simple case.

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

description: Devices for nano- and molecular size electronics are currently a focus of research aimed at an efficient current rectification and switching. A few generic molecular scale devices are reviewed here on the basis of first-principles and model approaches. Current rectification by (ballistic) molecular quantum dots can produce the rectification ratio ~100. Current switching due to conformational changes in the molecules is slow, on the order of a few kHz. Fast switching (~1THz) may be achieved, at least in principle, in a degenerate molecular quantum dot with strong coupling of electrons with vibrational excitations. We show that the mean-field approach fails to properly describe intrinsic molecular switching and present an exact solution to the problem. Defects in molecular films result in spurious peaks in conductance, apparent negative differential resistance, and may also lead to unusual temperature and bias dependence of current. The observed switching in many cases is_extrinsic_, caused by changes in molecule-electrode geometry, molecule reconfiguration, metallic filament formation through, and/or changing amount of disorder in a molecular film. We give experimental examples of telegraph "switching" and "hot spot" formation in the molecular films.

description: Quantum machine learning explores the interplay between machine learning and quantum physics, which may lead to unprecedented perspectives for both fields. In fact, recent works have shown strong evidences that quantum computers could outperform classical computers in solving certain notable machine learning tasks. Yet, quantum learning systems may also suffer from the vulnerability problem: adding a tiny carefully-crafted perturbation to the legitimate input data would cause the systems to make incorrect predictions at a notably high confidence level. In this paper, we study the universality of adversarial examples and perturbations for quantum classifiers. Through concrete examples involving classifications of real-life images and quantum phases of matter, we show that there exist universal adversarial examples that can fool a set of different quantum classifiers. We prove that for a set of $k$ classifiers with each receiving input data of $n$ qubits, an $O(\frac{\ln k} {2^n})$ increase of the perturbation strength is enough to ensure a moderate universal adversarial risk. In addition, for a given quantum classifier we show that there exist universal adversarial perturbations, which can be added to different legitimate samples and make them to be adversarial examples for the classifier. Our results reveal the universality perspective of adversarial attacks for quantum machine learning systems, which would be crucial for practical applications of both near-term and future quantum technologies in solving machine learning problems.

description: In this paper I present the detail estimations for the width of the 511 keV line produced by a mechanism when dark matter is represented by macroscopically large dense nuggets. I argue that the width of 511 keV emission in this mechanism is very narrow (in a few keV range) in agreement with all observations. The dominant mechanism of the annihilation in this case is the positronium formation e^+e^-to ^1S_0 to 2γrather than a direct e^+e^- to 2γ$ annihilation. I also discuss some generic features of the γrays spectrum (in few MeV range) resulting from this mechanism.

description: Description of periodically and resonantly driven quantum systems can lead to solid state models where condensed matter phenomena can be investigated in time lattices formed by periodically evolving Wannier-like states. Here, we show that inseparable two-dimensional time lattices with the Möbius strip geometry can be realized for ultra-cold atoms bouncing between two periodically oscillating mirrors. Effective interactions between atoms loaded to a lattice can be long-ranged and can be controlled experimentally. As a specific example we show how to realize a Lieb lattice model with a flat band and how to control long-range hopping of pairs of atoms in the model.

description: We present ~0.15'' spatial resolution imaging of SHiZELS-14, a massive (M*~10^11 M_sol), dusty, star-forming galaxy at z=2.24. Our rest-frame ~1kpc-scale, matched-resolution data comprise four different widely used tracers of star formation: the H-alpha emission line (from SINFONI/VLT), rest-frame UV continuum (from HST F606W imaging), the rest-frame far-infrared (from ALMA), and the radio continuum (from JVLA). Although originally identified by its modest H-alpha emission line flux, SHiZELS-14 appears to be a vigorously star-forming (SFR~1000 M_sol/yr) example of a submillimeter galaxy, probably undergoing a merger. SHiZELS-14 displays a compact, dusty central starburst, as well as extended emission in $\rm{H}α$ and the rest-frame optical and FIR. The UV emission is spatially offset from the peak of the dust continuum emission, and appears to trace holes in the dust distribution. We find that the dust attenuation varies across the spatial extent of the galaxy, reaching a peak of at least A_H-alpha~5 in the most dusty regions, although the extinction in the central starburst is likely to be much higher. Global star-formation rates inferred using standard calibrations for the different tracers vary from ~10-1000 M_sol/yr, and are particularly discrepant in the galaxy's dusty centre. This galaxy highlights the biased view of the evolution of star-forming galaxies provided by shorter wavelength data.

description: Reversible spin Hall effect comprising the "direct" and "inverse" spin Hall effects was successfully detected at room temperature. This experimental demonstration proves the fundamental relations called Onsager reciprocal relations between spin and charge currents. A platinum wire with a strong spin-orbit interaction is used not only as a spin current absorber but also as a spin current source in the present lateral structure specially designed for clear detection of both charge and spin accumulations via the spin-orbit interaction. The obtained spin Hall conductivity is much larger than the reported value of Aluminum wire because of the larger spin-orbit interaction.

description: Τα τελευταία χρόνια το τραπεζικό σύστημα πολλών χωρών έχει εμφανίσει υψηλά επίπεδα μη εξυπηρετούμενων δανείων, τα οποία ελλοχεύουν κινδύνους τόσο για τη ρευστότητα των πιστωτικών ιδρυμάτων, όσο για την παγκόσμια οικονομία. Η παρούσα μελέτη επικεντρώνεται στην νομική αντιμετώπιση των «κόκκινων δανείων». Χωρίζεται σε τέσσερα κεφάλαια. Το πρώτο επικεντρώνεται στην έννοια των ΜΕΔ και στα προβλήματα που δημιουργούν στην οικονομία και κάνει μια σύντομη αναδρομή στο νομοθετικό πλαίσιο της χώρας. Το δεύτερο παρουσιάζει την προοπτική «αποξένωσης» του πιστωτικού ιδρύματος από το προβληματικό τους χαρτοφυλάκιο μέσω του ν. 4354/2015. Το τρίτο κεφάλαιο εμβαθύνει στους εξωδικαστικούς κυρίως, τρόπους ρύθμισης των προβληματικών δανείων, με τον εντοπισμό της καλύτερης λύσης για τον δανειολήπτη (Κώδικας Δεοντολογίας, Εξωδικαστικός Μηχανισμός, ν. 3869/2010) Τέλος, στο τέταρτο αναφέρονται κάποιοι τρόποι πρόληψης, που έχουν προβλεφθεί από την Ευρωπαϊκή ‘Ένωση, προκειμένου να αποφευχθεί μια καινούργια γενιά μη εξυπηρετούμενων δανείων
description: Most recently, various banking systems have been prone to a large number of non-performing loans, resulting in imminent cash flow risks for both the private credit institutions and the global economy. This study focuses on the legal treatment of non-performing loans (NPLs) and is divided in four main chapters. Firstly, a review for NPLs and their respective Greek legislative framework have been made, where also their impact on economy has been discussed. Secondly, the approach followed by the credit institutions (via the 4354/2015) to smoothen their challenging relationship with the borrower has been presented. Moving on, a thorough assessment of out-of-court controlling mechanisms concentrated on finding the optimal solution for the mortgage holder has been considered (Code of Contact, Out-of-Court settlement, ν. 3869/2010). In the final chapter we present some of the preventing measures developed by European Union to reduce the chances of evolution of new NPLs

description: Nanoparticles (NPs) have been widely used in biomedical field for therapeutic treatments, drug carriers, and bio-imaging agent. Recent studies have highlighted the possibility of utilizing inorganic NPs in inducing endothelial leakiness through endothelial remodeling to promote drug transport across the barrier. However, an uncontrolled and persistent leakiness could lead to promiscuous transport of molecules and cells across the barrier, highlighting the pressing need to control the timely recovery from endothelial cell leakiness. Herein, we show that angiopoietin-1 (Ang1) could promote recovery of human microvascular endothelial cells (HMVECs) from titanium dioxide nanoparticle (TiO2 NPs)-induced endothelial leakiness. Ang1 is known as an anti-permeability growth factor which forms complexes with its receptor Tie2 at the cell-to-cell junctions. We find that the introduction of Ang1 not only accelerates the recovery of NP-induced endothelial leakiness (NanoEL) but also promotes cell rigidity by increasing tubulin acetylation, thereby remodels the endothelial cells to further mitigate the effects of NP exposure through the activation of the Akt pathway. Using in vitro metastasis model, we further show that HMVECs treated with TiO2 NPs followed by Ang1 could reduce migration of human skin cancer A431 cells across the endothelial barrier. In summary, Ang1 plays important roles in promoting the recovery of endothelial cell leakiness and endothelial stability through a mechano-transduction pathway and shows great potential as key modulator that allows material scientist to regulate endothelial leakiness induced by NPs.

Προαπαιτούμενο για την ανάλυση του ζητήματος είναι η προσέγγιση της έννοια της «ταυτότητας της πράξης». Για το λόγο αυτό, στο πρώτο μέρος της εργασίας, γίνεται ανάλυση της έννοιας του δεδικασμένου και της αρχής «ne bis in idem», με αναφορά τόσο των θέσεων της θεωρίας, όσο και εκείνων της νομολογίας. Στο δεύτερο μέρος της διπλωματικής εργασίας, αναλύονται οι επιμέρους προϋποθέσεις του άρθρου 550 ΚΠΔ και επισημαίνονται τα ερμηνευτικά προβλήματα που ανακύπτουν, όπως το ποιά ποινή θεωρείται ελαφρύτερη και άρα θα εκτελεσθεί. Εν συνεχεία, η διπλωματική πραγματεύεται τα ιδιαιτέρως δυσχερή ζητήματα του κατ’ εξακολούθηση εγκλήματος και της αληθινής συρροής επί τη βάσει του άρθρου 550 ΚΠΔ. Τέλος, γίνεται συσχέτιση της διάταξης του άρθρου 550 ΚΠΔ με εκείνη του άρθρου 562 ΚΠΔ περί αμφιβολιών, αλλά και ανάλυση του θέματος των ενδίκων μέσων κατά της απόφασης
description: This thesis is an interpretive approach to Article 550 of the Criminal Procedure Code (CPC), giving rise to the possibility of more convictions towards the same crime. The approach of the concept "identity of the act" is a prerequisite for the analysis of this issue. For this reason, in its first part, this thesis analyzes the concept of precedents and the “ne bis in idem" principle, with reference to both the positions of theory and jurisprudence. In the second part of the thesis, the particular conditions of Article 550 CPC are being analyzed and the interpretive problems that arise -such as, which sentence is considered lighter and will, therefore, be executed- are highlighted. Subsequently, this paper addresses the particularly difficult issues of continuous offenses and real concurrence of offenses, under the scope of Article 550 CPC. Finally, Article 550 CPC is being correlated with Article 562 CPC regarding ambiguities and an analysis of the issue of appeals against the judicial decision is attempted

Performance and emission characteristics of a gas-diesel engine

description: The performance and emission characteristics of high pressure injection of natural gas with liquid pilot-diesel fuel (ie. gas-diesel operation) was investigated in a single-cylinder, two-stroke compression-ignition engine with a poppet-valve gas-diesel injector. The investigated injector geometries and engine operating parameters included: fuel injection angle, fuel jet interruption ratio, engine speed, load, beginning of injection timing, natural gas injection pressure, pilot-diesel to total-fuel energy ratio and pilot-diesel cetane number. These parameters were found to have very strong effects on thermal efficiency and exhaust emissions (ie. NOx, THC, CH₄, CO, CO₂ and BOSCH smoke index). The thermal efficiency and exhaust emissions were determined as a function of load (ie. BMEP). The thermal efficiency of the optimum gas-diesel operation was shown to exceed that of the conventional diesel operation at full load, but was lower at low load. With this gas-diesel injector configuration, it was found that the pilot-diesel fuel was not mixed well enough to burn completely. A new gas-diesel injector designed to overcome this drawback is in process. A three-zone combustion and exhaust emission analysis model was established to deduce ignition delay from cylinder pressure data with crank angle. At low loads, it was found that the ignition delay of natural gas was excessive with very late burning and consequently low thermal efficiency. At high loads, the ignition delay of natural gas was considerably longer than that of diesel fuelling, but not so long as to affect the thermal efficiency. The three-zone model was also used to deduce maximum burned-gas temperature. It was found that equilibrium NO concentration calculated from this temperature and cylinder pressure can be used to correlate the exhaust NO measured from engine exhaust pipe.

description: Lithium-Niobate-On-Insulator (LNOI) is emerging as a promising platform for integrated quantum photonic technologies because of its high second-order nonlinearity and compact waveguide footprint. Importantly, LNOI allows for creating electro-optically reconfigurable circuits, which can be efficiently operated at cryogenic temperature. Their integration with superconducting nanowire single-photon detectors (SNSPDs) paves the way for realizing scalable photonic devices for active manipulation and detection of quantum states of light. Here we report the first demonstration of these two key components integrated in a low loss (0.2 dB/cm) LNOI waveguide network. As an experimental showcase of our technology, we demonstrate the combined operation of an electrically tunable Mach-Zehnder interferometer and two waveguide-integrated SNSPDs at its outputs. We show static reconfigurability of our system with a bias-drift-free operation over a time of 12 hours, as well as high-speed modulation at a frequency up to 1 GHz. Our results provide blueprints for implementing complex quantum photonic devices on the LNOI platform.
