description: We study perturbative unitarity constraints on generic Yukawa interactions where the involved fields have arbitrary quantum numbers under an $\prod_i SU(N_i) \otimes U(1)$ group. We derive compact expressions for the bounds on the Yukawa couplings for the cases where the fields transform under the trivial, fundamental or adjoint representation of the various $SU(N)$ factors. We apply our results to specific models formulated to explain the anomalous measurements of $(g-2)_μ$ and of the charged- and neutral-current decays of the $B$ mesons. We show that, while these models can generally still explain the observed experimental values, the required Yukawa couplings are pushed at the edge of the perturbative regime.

description: In this work, we study the electric and magnetic Sachs form factors for proton and neutron by using a deformed gravity/gauge model. We describe holographically baryons as well as gauge bosons which are ruled by the parameters $k_{B}$ and $k_γ$, associated with confinement and kinematical energy scales, respectively. Then, we construct the interaction action and calculate the electric and magnetic form factors for the proton and the neutron, and their electromagnetic sizes. The obtained results are compatible with those found in the literature from experimental and theoretical data.

description: We study the Josephson current in a junction comprising two superconductors linked by a strong ferromagnet in presence of impurities. We focus on a regime where the electron (and hole) motion is ballistic over the exchange length and diffusive on the scale of the weak link length. The current-phase relation is obtained for both two- and three dimensional ferromagnetic weak links. In the clean limit, the possibility of temperature-induced 0- transitions is demonstrated while the corresponding critical current versus temperature dependences are also studied.

Blood lactate reduction at three recovery intensities following severe rowing excercise
Creators: name: Anderson, Scott Cameron
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to observe the differences in rates of blood lactate reduction (BLR) at three recovery intensities (40% VO₂max, 60% V02max, and combined recovery ) when subjects are highly trained and aerobically fit. Eight well-trained oarsmen (age = 23.2 yr, Ht = 189.6 cm, Wt = 85.3 kg, VO₂max = 5.2 1 / min or 61.6 ml / kg min⁻¹) were tested in one pre-experimental procedure and three experimental treatments. The pre-experimental procedure involved the determination of VO₂max, and the loads at which 40 -, 50 -, and 60% VO₂max occurred from a progressive load VO₂max. The three experimental treatments each involved three one minute maximal load intervals on the rowing ergometer to elevate blood lactate, followed by a 30 minute randomly assigned recovery on the rowing ergometer at either 40% VO₂max (40R), 60% VO₂max (60R), or combined recovery (CR). Blood samples, from an indwelling catheter placed in the cephalic vein, were taken at t=0,1, 2, 3, 4, 5, 6, 9,12,15,18, 21, 24, 27, and 30 min of recovery. Analysis of plasma samples revealed a mean resting blood lactate concentration ( [ Bla ] ) of 1.2 mM and a mean peak [ Bla ] following maximal exercise of 16.3 mM. ANOVA indicated that no significant differences occurred between the rates of lactate reduction for the three treatments (p<.055). With p<.055 and an effect size of eta=.31, further testing using a post-hoc multicomparison analysis revealed a significantly faster (p<.05) rate of BLR during the 60R treatment when compared to the rate of BLR for 40R. No further differences were revealed between any of the other comparisons (40R vs CR, or 60R vs CR). The significant differences between the rate of BLR for 60R compared to 40R may be due to the subjects' high aerobic fitness, the specific nature of both their training and the recovery task, and physiological adaptations related to a high fitness level.

description: We discuss the conservation of angular momentum in nuclear time-dependent Hartree-Fock calculations for a numerical representation of wave functions and potentials on a three-dimensional cartesian grid. Free rotation of a deformed nucleus performs extremely well even for relatively coarse spatial grids. Heavy ion collisions produce a highly excited compound system associated with substantial nucleon emission. These emitted nucleons reach the bounds of the numerical box which leads to a decrease of angular momentum. We discuss strategies to distinguish the physically justified loss from numerical artifacts.

description: We present first results of our simulations of magnetic fields in the formation of single and binary stars using a recently developed method for incorporating Magnetohydrodynamics (MHD) into the Smoothed Particle Hydrodynamics (SPH) method. An overview of the method is presented before discussing the effect of magnetic fields on the formation of circumstellar discs around young stars. We find that the presence of magnetic fields during the disc formation process can lead to significantly smaller and less massive discs which are much less prone to gravitational instability. Similarly in the case of binary star formation we find that magnetic fields, overall, suppress fragmentation. However these effects are found to be largely driven by magnetic pressure. The relative importance of magnetic tension is dependent on the orientation of the field with respect to the rotation axis, but can, with the right orientation, lead to a dilution of the magnetic pressure-driven suppression of fragmentation.

description: We present Hall-effect measurements of two-leg ladder compounds Sr_{14-x}Ca_xCu_24O_41 (0 <= x <= 11.5) with the aim to determine the number of carriers participating in dc transport. Distribution of holes between the ladder and chain subsystems is one of the crucial questions important for understanding the physics of these compounds. Our Hall effect and resistivity measurements show typical semiconducting behavior for x < 11.5. However, for x=11.5, the results are completely different, and the Hall coefficient and resistivity behavior is qualitatively similar to that of high temperature copper-oxide superconductors. We have determined the effective number of carriers at room temperature and compared it to the number of holes in the ladders obtained by other experimental techniques. We propose that going from x=0 to x=11.5 less than 1 hole per formula unit is added to the ladders and is responsible for a pronounced change in resistivity with Ca doping.

Invertible group actions are considered as possible candidates for stroboscopic maps of ordinary differential equations. It is shown that flow of the Bloch equation is a unique suspension of an invertible map on the SU(2) group.

description: The emergence of magnetic flux from the convection zone into the corona is an important process for the dynamical evolution of the coronal magnetic field. In this paper we extend our previous numerical investigations, by looking at the process of flux interaction as an initially twisted flux tube emerges into a plane parallel, coronal magnetic field. Significant differences are found in the dynamical appearance and evolution of the emergence process depending on the relative orientation between the rising flux system and any preexisting coronal field. When the flux systems are nearly anti-parallel, the experiments show substantial reconnection and demonstrate clear signatures of a high temperature plasma located in the high velocity outflow regions extending from the reconnection region. However, the cases that have a more parallel orientation of the flux systems show very limited reconnection and none of the associated features. Despite the very different amount of reconnection between the two flux systems, it is found that the emerging flux that is still connected to the original tube, reaches the same height as a function of time. As a compensation for the loss of tube flux, a clear difference is found in the extent of the emerging loop in the direction perpendicular to the main axis of the initial flux tube. Increasing amounts of magnetic reconnection decrease the volume, which confines the remaining tube flux.

Metodologie per il miglioramento dei processi nella raccolta, trasformazione e reimpiego del materiale di risulta delle costruzioni nelle opere civili.
Creators: name: De Simone, Angelo
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: Oggetto del  lavoro di tesi è lo studio dei processi legati alla trasformazione di una particolare categoria di rifiuti, i cosiddetti rifiuti inerti da costruzione e demolizione, al fine di studiarne possibili miglioramenti economici ed organizzativi che consentano, tra l’altro, una migliore e ben definita allocazione nel rispettivo mercato di riferimento.
L’ambito territoriale di riferimento per l’applicazione della metodologia di raccolta, trasformazione e reimpiego del materiale di risulta delle costruzioni nelle opere civili è stato individuato nel territorio incluso nella Comunità Montana Monte Santa Croce, sulle propaggini Nord del vulcano spento del Roccamonfina, in Provincia di Caserta.
Lo studio proposto cercherà quindi di mettere in evidenza come da un’analisi metodologica dell’intero ciclo di raccolta e trasformazione dei rifiuti da costruzione e demolizione si possano:
Trarre informazioni sulla conoscenza quantitativa, qualitativa ed organizzativa dell’attuale stato dell’arte nel campo degli aggregati riciclati;
Analizzare in maniera obiettiva i possibili impieghi di tali materiali, anche attraverso un confronto prestazionale tra  inerte riciclato ed il corrispettivo bene succedaneo di riferimento nell’ambito degli inerti naturali;
Utilizzare i dati derivanti dall’analisi per introdurre semplici miglioramenti o sostanziali cambiamenti sia sul ciclo di raccolta, sia sul processo di lavorazione attuato negli impianti che operano la trasformazione rifiuto/materia prima secondaria, sia sulla corretta allocazione del prodotto finale in base a considerazioni tecnico economiche.
 Lo  studio analizza pertanto l’intero processo di trasformazione del rifiuto inerte in materia prima secondaria, nell’ambito di un ben definito bacino di utenza. Non solo sono stati analizzati i mercati di riferimento dei beni prodotti, le  più diffuse tecnologie in uso presso le imprese che operano nel settore, ma con la metodologia proposta si è cercato di individuare, in base alle caratteristiche peculiari tipiche dell’area di riferimento, quali sono i migliori processi attuabili in fase di raccolta, le migliori tecnologie atte ad operare sugli specifici prodotti da questi derivati, la corretta allocazione del prodotto una volta immesso sul mercato.
Attraverso l’analisi economica, attuata tramite metodologie del tipo CBA e tecniche computazionali di tipo estimativo,  è stato poi proposto uno studio di fattibilità economico finanziario condotto per la Comunità Montana Monte Santa Croce che, a fronte di un quantitativo di materiale inerte utilizzato per le lavorazioni che più frequentemente realizza ed alla richiesta da parte dei Comuni  e dei privati di inerte per realizzare manufatti edilizi, abbia deciso di investire sulla realizzazione di un impianto di produzione di materie prime secondarie.
Coincidences between Gravitational Wave Interferometers and High Energy Neutrino Telescopes

description: Sources of gravitational waves (GW) and emitters of high energy (HE) neutrinos both involve compact objects and matter moving at relativistic speeds. GW emission requires a departure from spherical symmetry, which is the case if clumps of matter are accreted around black holes or neutron stars, and ejected in relativistic jets, where neutrinos are believed to be produced. Both messengers interact weakly with the surrounding matter, hence point directly to the heart of the engines that power these emissions. Coincidences between GW interferometers (e.g. Virgo) and HE neutrino telescopes (e.g. Antares) would then give a unique insight on the physics of the most powerful objects in the Universe. The possibility, observability and detectability for such GW/HE neutrino coincidences are analysed.

Proposal of a knowledge audit metric based upon a compared analysis in private and public organizations
Creators: name: Pietrantonio, Rinaldo
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: The Study approaches the organizational analysis known as knowledge-audit, and in particular proposes to extend the structure of the related models over the mere analysis of the organizational knowledge including the knowledge-management capabilities.
	A specific assessment-process of the knowledge-management capabilities is thus structured basing upon a specific grid whose components address the organization’s intellectual capital, from one side, and the main perspectives of the balanced-scorecard [Kaplan, Norton, 1996; 2001] from others. In particular, by applying such grid is here produced an estimate of the correlation occurring between the efficiency of the knowledge-management system and the business performances of the organization; and basing on such correlation it is defined a metric addressing the possible existing relationships among: (a) the support level provided by the knowledge-management system to the organization’s intellectual capital components; (b) the improvements of the same system achievable by taking a changes in some of the main constituting components (i.e. technology, personal competence, and personal motivation); and (c) the increases in the business performances. It is then proved that such metric not only allows to estimate the effectiveness of the knowledge-management systems but also allows to individuate those interventions, that must be taken to boost the capabilities of the same system, in terms of technology, personal motivation and personal competencies.
	Such metric is tested in the Study’s empirical part on two main samples constituted by different subjects; the first is constituted by two subgroups of private technology consulting firms - one operating worldwide and the other operating locally in the Southern Italy area; the second instead is constituted by several different public organizations that have been selected among Italian public administration bodies, Italian Public Agencies (i.e. INPS, Agenzia Dogane, etc.), public research centers, and international organizations. Specifically, the deep difference presumably existing between the samples in the progress of their own operational knowledge-management systems is here used as reference term to test the intrinsic consistency of such metric as very different values characterize the estimates produced by applying this metric: over proving the meaningfulness of the metric the positive exit of the test allows to define a quantitative estimate of the real divide existing between the subjects and to propose a related suitable strategy for improving the knowledge-management systems of the same subjects.
Evaluation of Unsupervised Entity and Event Salience Estimation

Year: 2021

description: Salience Estimation aims to predict term importance in documents. Due to few existing human-annotated datasets and the subjective notion of salience, previous studies typically generate pseudo-ground truth for evaluation. However, our investigation reveals that the evaluation protocol proposed by prior work is difficult to replicate, thus leading to few follow-up studies existing. Moreover, the evaluation process is problematic: the entity linking tool used for entity matching is very noisy, while the ignorance of event argument for event evaluation leads to boosted performance. In this work, we propose a light yet practical entity and event salience estimation evaluation protocol, which incorporates the more reliable syntactic dependency parser. Furthermore, we conduct a comprehensive analysis among popular entity and event definition standards, and present our own definition for the Salience Estimation task to reduce noise during the pseudo-ground truth generation process. Furthermore, we construct dependency-based heterogeneous graphs to capture the interactions of entities and events. The empirical results show that both baseline methods and the novel GNN method utilizing the heterogeneous graph consistently outperform the previous SOTA model in all proposed metrics.
Effect of the Photon's Brownian Doppler Shift on the Weak-Localization Coherent-Backscattering Cone

description: We report the first observation of the dependence of the coherent-backscattering (CBS) enhanced cone with the frequency of the backscattered photon. The experiment is performed on a diffusing liquid suspension and the Doppler broadening of light is induced by the Brownian motion of the scatterers. Heterodyne detection on a CCD camera is used to measure the complex field (i.e., the hologram) of the light that is backscattered at a given frequency. The analysis of the holograms yield the frequency and the propagation direction of the backscattered photons. We observe that the angular CBS cone becomes more narrow in the tail of the Brownian spectrum. The experimental results are in good agreement with a simple theoretical model.
Modellazione numerica dei fenomeni di trasporto solido in aree costiere

Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: I fenomeni di trasporto solido in ambiente marino costiero rappresentano una delle principali cause di modellamento ed erosione dei litorali sabbiosi, in quest’ultimo caso può essere estremamente utile disporre di strumenti analitici di tipo numerico per studiare e ricostruire i processi e le dinamiche evolutive delle coste e dei fondali.
Nel presente lavoro il problema del trasporto dei sedimenti non-coesivi, all’interno e all’esterno della surf-zone, è stato affrontato attraverso l’implementazione di un modello numerico basato su un approccio modellistico cosiddetto ‘process based’ (Haas & Hanes, 2004). In base a tale approccio, la dinamica costiera è stata scomposta dando un ruolo centrale alla simulazione di processi fisici (onde e correnti) e alla contemporanea riproduzione della risposta dinamica del sistema costiero che, nel caso del trasporto delle particelle sedimentarie, si traduce talvolta attraverso vistose variazioni morfobatimetriche.
L’obiettivo del lavoro è stato la realizzazione di uno strumento tipo ‘Coastal Area Model’ in grado di fornire, attraverso simulazioni numeriche, dati relativi al trasporto di sedimenti con particolare attenzione alla modellazione in tempo reale dei cambiamenti morfologici del fondale. Il ‘Coastal Area Model’ è costituito da due modelli numerici integrati tra cui avviene uno scambio continuo di dati, il primo di tipo idrodinamico per modellare la trasformazione del moto ondoso e la generazione di correnti longshore e cross-shore ed il secondo dedicato alla simulazione delle variazioni morfologiche e batimetriche dovute alla movimentazione dei sedimenti. Il modello idrodinamico è stato sviluppato a partire da codici open source, mentre il modello numerico dedicato alla simulazione del trasporto di sedimenti non coesivi è stato realizzato ‘ad hoc’ in modo da aggiornare progressivamente il dataset batimetrico per riprodurre il naturale feedback tra idrodinamismo e variazioni morfologiche del fondale.
L’insieme dei modelli numerici, ovvero il ‘Coastal Area Model’, dopo una prima fase di test, è stato applicato alla Baia dei Maronti (Isola d’Ischia (NA) – Mar Tirreno, Italia) al fine di analizzare la dinamica dei processi erosivi in atto e per prevedere attraverso opportune simulazioni le variazioni morfobatimetriche prodotte sia da una mareggiata estrema sia dall’onda morfologica che determina il modellamento a lungo termine della Baia.

We also investigate the limit to a black hole, which describes the BMPV black hole with the topology of the lens space L(2;1)=S^3/Z_2.

description: The paper estimates the political connection premium for Italian cities tracked during the second half of the 1900s, when the role of the state in the economy was very widespread. It leverages the peculiar features of the gridlocked political landscape in place between the end of World War II and the fall of the Berlin wall, during which most influential politicians remained in charge for a very long time. We compare connected cities - small areas surrounding birthplaces of both prime ministers and leaders of the parties in power - with very similar, but unconnected municipalities, and find that politically connected cities gained a population premium of 8% over 40 years. When the connection ends, the difference in growth rate fades away. We document that birthplaces of powerful politicians benefited from both infrastructure investments and the location of plants by state-owned enterprises. Not surprisingly, the connection favored industrialization, raised employment and wages, but crowded out private entrepreneurship. Finally, our empirical evidence indicates that agglomeration economies in treated municipalities were not higher, thus suggesting that, if anything, place-based interventions linked to political connections have not been output-enhancing from a nationwide point of view.

description: We describe the X-ray pulse profile models we use, and how we use them, to analyze Neutron Star Interior Composition Explorer (NICER) observations of rotation-powered millisecond pulsars to obtain information about the mass-radius relation of neutron stars and the equation of state of the dense matter in their cores. Here we detail our modeling of the observed profile of PSR J0030+0451 that we analyzed in Miller et al. (2019) and Riley et al. (2019) and describe a cross-verification of computations of the pulse profiles of a star with R/M 3, in case stars this compact need to be considered in future analyses. We also present our early cross-verification efforts of the parameter estimation procedures used by Miller et al. (2019) and Riley et al. (2019) by analyzing two distinct synthetic data sets. Both codes yielded credible regions in the mass-radius plane that are statistically consistent with one another and both gave posterior distributions for model parameter values consistent with the values that were used to generate the data. We also summarize the additional tests of the parameter estimation procedure of Miller et al. (2019) that used synthetic pulse profiles and the NICER pulse profile of PSR J0030+0451. We then illustrate how the precision of mass and radius estimates depends on the pulsar's spin rate and the size of its hot spot by analyzing four different synthetic pulse profiles. Finally, we assess possible sources of systematic error in these estimates made using this technique, some of which may warrant further investigation.

description: The couplings $g_{ρHH}$ of the $ρ$ meson with any hadron H are calculated in a holographic dual of QCD where the Regge trajectories for mesons are manifest. The resulting couplings grow linearly with the exciting number of H, thus are far from universal. A simple argument has been given for this behavior based on quasi-classical picture of excited hadrons. It seems that in holographic duals with exact Regge trajectories the $g_{ρHH}$ universality should be violated. The $ρ$-dominance for the electromagnetic form factors of H are also strongly violated, except for the lowest state, the pion. Quite unexpected, the form factor of the pion is completely saturated by the contribution of the $ρ$. The asymptotic behavior of the form factors are also calculated, and are found to be perfectly accordant with the prediction of conformal symmetry and pertubative QCD.

description: The high-pressure dynamics of a computer-modeled silica melt is studied in the framework of the mode-coupling theory of the glass transition (MCT) using static-structure input from molecular-dynamics (MD) computer simulation. The theory reproduces the experimentally known viscosity minimum (diffusivity maximum) as a function of density or pressure and explains it in terms of a corresponding minimum in its critical temperature. This minimum arises from a gradual change in the equilibrium static structure which shifts from being dominated by tetrahedral ordering to showing the cageing known from high-density liquids. The theory is in qualitative agreement with computer simulation results.

description: Inevitable for the basic principles of skyrmion racetrack-like applications is not only their confined motion along one-dimensional channels but also their controlled creation and annihilation. Helical magnets have been suggested to naturally confine the motion of skyrmions along the tracks formed by the helices, which also allow for high-speed skyrmion motion. We propose a protocol to create topological magnetic structures in a helical background. We furthermore analyse the stability and current-driven motion of the skyrmions in a helical background with in-plane uniaxial anisotropy fixing the orientation of the helices.

The first is a developing country with a broad industrial base. The second is a developed country which is still essentially resource-exporting inspite of its sophisticated technology and industry. A plea has been made for international regulation of foreign direct investment in order to make it a truly effective tool of economic growth and development. The costs and benefits of foreign direct investment have been examined in Chapter 1 with special emphasis on developing countries. Attempts have been made in various international forums to develop a mechanism to regulate foreign direct investment. UN has made the most comprehensive effort with the appointment of the Group of Eminent Persons in 1972. Their recommendations and the accompanying comments have been discussed to highlight the divergence of views between developing and developed countries. The impact of colonization on developing countries with its consequent problems like formation of resource-based economies has been discussed in Chapter II. Canada being a largely resource-exporting economy inextricably linked with USA has several parallels with developing countries. In Chapter 3 I have discussed the historical background of foreign direct investment in India and its perceived costs. Provisions of Foreign Exchange Regulation Act, 1973 have been examined to assess India's attempts to regulate foreign direct investment. Chapter 4 has dealt with the role of foreign direct investment in Canadian economy and its perceived costs and benefits. Foreign Investment Review Act, 1973 and Investment Canada Act, 1985 have been analysed to understand Canada's attempts at regulation of foreign direct investment. The Draft Code of Conduct produced by the UN Comission on Transnational Corporations has been discussed in Chapter 5. Areas of international agreement and disagreement have been classified and possible solutions seen to make this a universally acceptable code. I have concluded that it would be beneficial to adopt a universally acceptable international code of conduct. This can eventually acquire the force of customary international law and provide guidelines for national legislation to make foreign direct investment an effective tool in economic development.

description: According to the scheme of action of the solar dynamo, the poloidal magnetic field can be considered a source of production of the toroidal magnetic field by the solar differential rotation. From the polar magnetic field proxies, it is natural to expect that solar Cycle 25 will be weak as recorded in sunspot data. We suggest that there are parameters of the zonal harmonics of the solar surface magnetic field, such as the magnitude of the $\ell$=3 harmonic or the effective multipole index, that can be used as a reasonable addition to the polar magnetic field proxies. We discuss also some specific features of solar activity indices in Cycles 23 and 24.

description: In this study, we survey the generalized Duffin-Kemmer-Petiau oscillator containing a non-minimal coupling interaction in the context of rainbow gravity in the presence of cosmic topological defects in space-time. In this regard, we intend to investigate relativistic quantum dynamics of a spin-0 particle under the modification of the dispersion relation according to the Katanaev-Volovich geometric approach. Thus, based on the geometric model, we study the aforementioned bosonic system under the modified background by a few rainbow functions. In this way, by using an analytical method, we acquire energy eigenvalues and corresponding wave functions corresponding to each scenario. Regardless of rainbow gravity function selection, the energy eigenvalue can present symmetric, anti-symmetric, and symmetry breaking characteristics. Besides, one can see that the deficit angular parameter plays an important role in the solutions.

description: We show that the very light spin-1 gauge U-boson of the extra $U(1)'$ gauge model in the framework of the supersymmetric standard model extension can be a good candidate of the new light particle suggested by the HyperCP experiment. We demonstrate that the flavor changing neutral currents (FCNCs) for the HyperCP events in the decay of $Σ^{+}\to p μ^{+} μ^{-}$ can be generated at both tree and loop levels. In particular, we find that the loop induced $s\to d U$ transition due to the tensor-type interaction with the dimension-5 electric dipole operator plays a very important role on the FCNCs. Our explanation of the HyperCP data with the spin-1 U-boson is different from that based on a light pseudoscalar Higgs boson or sgoldstino in the literature. In particular, the U-boson involves a rich phenomenology in particle physics as well as cosmology.

description: We present detailed calculations at the basis of our recent proposal for simultaneous cooling the rotational, vibrational and external molecular degrees of freedom. In this method, the molecular rovibronic states are coupled by an intense laser and an optical cavity via coherent Raman processes enhanced by the strong coupling with the cavity modes. For a prototype system, OH, we showed that the translational motion is cooled to few micro Kelvin and the molecule is brought to the internal ground state in about a second. Here, we investigate numerically the dependence of the cooling scheme on the molecular polarizability, selecting NO as a second example. Furthermore, we demonstrate the general applicability of the proposed cooling scheme to initially vibrationally and rotationally hot molecular systems.

description: The early outcome prediction of ongoing or completed processes confers competitive advantage to organizations. The performance of classic machine learning and, more recently, deep learning techniques such as Long Short-Term Memory (LSTM) on this type of classification problem has been thorougly investigated. Recently, much research focused on applying Convolutional Neural Networks (CNN) to time series problems including classification, however not yet to outcome prediction. The purpose of this paper is to close this gap and compare CNNs to LSTMs. Attention is another technique that, in combination with LSTMs, has found application in time series classification and was included in our research. Our findings show that all these neural networks achieve satisfactory to high predictive power provided sufficiently large datasets. CNNs perfom on par with LSTMs; the Attention mechanism adds no value to the latter. Since CNNs run one order of magnitude faster than both types of LSTM, their use is preferable. All models are robust with respect to their hyperparameters and achieve their maximal predictive power early on in the cases, usually after only a few events, making them highly suitable for runtime predictions. We argue that CNNs' speed, early predictive power and robustness should pave the way for their application in process outcome prediction.
