Abstract:

Parametric granular computing classification algorithms lead to difficulties in terms of parameter selection, the multiple performance times of algorithms, and increased algorithm complexity in comparison with nonparametric algorithms. We present nonparametric hyperbox granular computing classification algorithms (NPHBGrCs). Firstly, the granule has a hyperbox form, with the beginning point and the endpoint induced by any two vectors in N-dimensional (N-D) space. Secondly, the novel distance between the atomic hyperbox and the hyperbox granule is defined to determine the joining process between the atomic hyperbox and the hyperbox. Thirdly, classification problems are used to verify the designed NPHBGrC. The feasibility and superiority of NPHBGrC are demonstrated by the benchmark datasets compared with parametric algorithms such as HBGrC.

Abstract:

A method, called HACO2 (Hyperbox classifier with Ant Colony Optimization - type 2), is proposed for evolving a hyperbox classifier using the ant colony meta-heuristic. It reshapes the hyperboxes in a near-optimal way to better fit the data, improving the accuracy and possibly indicating its most discriminative features. HACO2 is validated using artificial 2D data showing over 90% accuracy. It is also applied to the benchmark iris data set (4 features), providing results with over 93% accuracy, and to the MIS data set (11 features), with almost 85% accuracy. For these sets, the two most discriminative features obtained from the method are used in simplified classifiers which result in accuracies of 100% for the iris and 83% for the MIS data sets. Further modifications (automatic parameter setting), extensions (initialization short comings) and applications are discussed.

Abstract:

Bottom-up and top-down are two main computing models in granular computing by which the granule set including granules with different granularities. The top-down hyperbox granular computing classification algorithm based on isolation, or IHBGrC for short, is proposed in the framework of top-down computing model. Algorithm IHBGrC defines a novel function to measure the distance between two hyperbox hgranules, which is used to judge the inclusion relation between two hyperbox granules, the meet operation is used to isolate the ith class data from the other class data, and the hyperbox granule is partitioned into some hyperbox granules which include the ith class data. We compare the performance of IHBGrC with support vector machines and HBGrC, for a number of two-class problems and multiclass problems. Our computational experiments showed that IHBGrC can both speed up training and achieve comparable generalization performance.

Abstract:

The uncertainty of the engineering system increases with the growing complexity of the engineering system; therefore, the tolerance to the uncertainty is essential. In the design phase, the output performance should reach the design criterion, even under large variations of design parameters. The tolerance to design parameter variations may be measured by the size of a solution space in which the output performance is guaranteed to deliver the required performance. In order to decouple dimensions, a maximum solution hyperbox, expressed by intervals with respect to each design parameter, is sought. The proposed approach combines the metaheuristic algorithm with the DIRECT algorithm where the former is used to seek the maximum size of hyperbox, and the latter is used as a checking technique that guarantees the obtained hyperbox is indeed a solution hyperbox. There are three advantages of the proposed approach. First, it is a global search and has a considerable high possibility to produce the globally maximum solution hyperbox. Second, it can be used for both analytically known and black-box performance functions. Third, it guarantees that any point selected within the obtained hyperbox satisfies the performance criterion as long as the performance function is continuous. Furthermore, the proposed approach is illustrated by numerical examples and real examples of complex systems. Results show that the proposed approach outperforms the GHZ and CES-IA methods in the literature.

Abstract:

Machine learning tools can be applied to peptide-mediated biomineralization, which is an emerging biomimetic technique of creating functional nanomaterials. In particular, they can be used for the discovery of biomineralization peptides, which currently relies on combinatorial enumeration approaches. In this work, an enhanced hyperbox classifier is developed which can predict if a given peptide sequence has a strong or weak binding affinity towards a gold surface. A mixed-integer linear program is formulated to generate the rule-based classification model. The classifier is optimized to account for false positives and false negatives, and clearly articulates how the classification decision is made. This feature makes the decision-making process transparent, and the results easy to interpret for decision support. The method developed can help accelerate the discovery of more biomineralization peptide sequences, which may expand the utility of peptide-mediated biomineralization as a means for nanomaterial synthesis.

Abstract:

A novel adaptive fuzzy min-max neural network classifier called AFMN is proposed in this paper. Combined with principle component analysis and adaptive genetic algorithm, this integrated system can serve as a supervised and real-time classification technique. Considering the loophole in the expansion-contraction process of FMNN and GFMN and the overcomplex network architecture of FMCN, AFMN maintains the simple architecture of FMNN for fast learning and testing while rewriting the membership function, the expansion and contraction rules for hyperbox generation to solve the confusion problems in the hyperbox overlap region. Meanwhile, principle component analysis is adopted to finish dataset dimensionality reduction for increasing learning efficiency. After training, the confidence coefficient of each hyperbox is calculated based on the distribution of samples. During classifying procedure, utilizing adaptive genetic algorithm to complete parameter optimization for AFMN can also fasten the entire procedure than traversal method. For conditions where training samples are insufficient, data core weight updating is indispensible to enhance the robustness of classifier and the modified membership function can adjust itself according to the input varieties. The paper demonstrates the performance of AFMN through substantial examples in terms of classification accuracy and operating speed by comparing it with FMNN, GFMN, and FMCN.

Abstract:

Few works have created such memorable characters as the Iliad and Odyssey. Readers come away from these works with the impression that the characters described in the stories are larger than life: Achilles is strong, Ajax is enormous, Patroclus is bloodthirsty, Nestor is ancient, Stentor is loud. Nobody leaves Homer’s epics thinking his heroes are not worthy of their lasting fame. This study argues that, although the heroes of the two Homeric epics are meant to be impressive, their characterization in the Iliad and Odyssey is the result of a process of rationalization whereby the hyperbole traditionally ascribed to such figures was toned down when the two poems were finally committed to writing. I argue this by showing that the hyperbole used to describe these heroes is paralleled across many Indo-European epic traditions and that, for the most part, it is much more exaggerated in these related epics. From the scant remains of the Epic Cycle, there is reason to believe that the context in which Homeric poetry was formed was receptive to the fantastic. The best explanation of these two pieces of data is that the Iliad and the Odyssey rationalize traditional hyperbole. This was done so that the poems would have a broader appeal and greater clarity, vividness, and simplicity, traits which have long been considered hallmarks of Homer’s style.

Este trabalho apresenta uma técnica para treinamento de Redes Neurais Artiﬁciais (RNA), capaz de obter os parâmetros da rede através dos dados disponíveis para treinamento, sem necessidade de estabelecer a arquitetura da rede a priori, denominado Método de Segmentações Geométricas Sucessivas (MSGS). O MSGS agrupa os dados de cada classe em Hipercaixa (HC) onde cada caixa é alinhada de acordo com os eixos de maior distribuição de seu conjunto de pontos. Sendo as caixas linearmente separáveis, um hiperplano de separação é identiﬁcado originando um neurônio. Caso não seja possível a separação por um único hiperplano, uma técnica de quebra é aplicada para dividir os dados em classes menores para obter novas HCs. Para cada subdivisão novos neurônios são adicionados à rede. Os resultados dos testes realizados apontam para um método rápido e com alta taxa de sucesso.
This work presents a technique for Artiﬁcial Neural Network (ANN) training, able to get the network parameters from the available data for training, without establishing the network architecture a priori, called Successive Geometric Segmentation Method (SGSM). The SGSM groups the data of each class into hyperboxes (HB) aligned in accordance with the largest axis of its points distribution. If the HB are linearly separable, a separating hyperplane may be identiﬁed resulting a neuron. If it is not, a segmentation technique is applied to divide the data into smaller classes for new HB. For each subdivision new neurons are added to the network. The tests show a rapid method with high success rate.

Abstract:

A basic assumption in fundamental physics is that equal amounts of matter and antimatter were created after the Big Bang. When particles and antiparticles collide, they annihilate, i.e. disappear and produce photons. Nevertheless, the universe consists mainly of matter today. To explain why all matter did not disappear, violation of CP symmetry beyond the Standard Model is required. CP symmetry means that the laws of physics are the same if particles are interchanged with antiparticles and spatial coordinates of all particles are mirrored. CP symmetry is relatively poorly tested in baryon decays. A new method to study CP symmetry in hyperon-antihyperon pairs has been developed at Uppsala University. Hyperons are baryons with one or more strange quarks. The method allows determining the decay asymmetry parameters of the hyperon and antihyperon separately if the hyperon-antihyperon pair is polarized. If any signiﬁcant diﬀerence between the magnitudes of these parameters is found, the process is CP violating. The particle physics experiment BESIII in China is a suitable experiment to conduct this kind of measurements because it is a high precision experiment and has collected large data samples of hyperon-antihyperon pairs. The goal of this project was to study statistical precisions of the physics parameters that can be obtained with the new method in cases of J/ψ meson decaying into ΛΛ, Σ+Σ− and Σ0Σ0. High statistical precision is required to detect CP violation, because CP violating processes are, if they exist, expected to be rare. The main focus was to study the process e+e− → J/ψ → Σ0Σ0 → ΛγΛγ → pπ−γpπ+γ. In this process, CP symmetry can be tested in two decay processes: electromagnetic decay Σ0 → Λγ and weak decay Λ → pπ−. Only the asymmetry parameter of Λ → pπ− was studied. The study served as a validity check of the new method and ongoing analyses at BESIII. The statistical precision was studied by simulations: Monte Carlo data samples were created and then a maximum-log-likelihood ﬁt was applied to the samples. An important component when determining the asymmetry parameters turned out to be the relative phase ∆φJ/ψ. The relative phase is one of the parameters used for determining the relation between the electric and magnetic form factors. ∆φJ/ψ is also related to the polarization of the hyperon-antihyperon pair. The study showed that the value of ∆φJ/ψ has a large impact on the uncertainties of the hyperon and antihyperon asymmetry parameters. A low value of ∆φJ/ψ resulted in high uncertainties and strong correlations between the asymmetry parameters. The formalism is diﬀerent for diﬀerent processes, which aﬀects the uncertainties as well. The formalism used for the Σ0Σ0 process gives poorer parameter precision of the asymmetry parameter related to the Λ → pπ− decay than the formalism used for the ΛΛ process. Therefore, the ΛΛ process is a much more suitable process for CP studies of the Λ → pπ− decay.
Ett grundantagande inom den fundamentala fysiken är att lika stora mängder av materia och antimateria skapades efter Big Bang. När partiklar och antipartiklar kolliderar, annihilerar de, dvs försvinner och producerar fotoner. Trots detta består dagens universum huvudsakligen av materia. För att förklara varför all materia inte försvann krävs ett brott mot CP-symmetrin bakom standardmodellen. CP-symmetrin innebär att fysikens lagar är desamma om man byter partiklar mot antipartiklar och speglar partikelns rumsliga koordinater. CP-symmetri i baryonsönderfall är relativt dåligt testad. En ny metod för att studera CP-symmetrin har utvecklats vid Uppsala universitet för hyperon-antihyperon par. Hyperoner är baryoner med en eller ﬂer särkvarkar. Metoden gör det möjligt att bestämma asymmetriparametrar hos hyperon- och antihyperonsönderfall separat om hyperonantihyperonparet är polariserat. Om en signiﬁkant skillnad mellan värden av dessa parametrar upptäcks, är processen CP-brytande. Partikelfysikexperimentet BESIII i Kina är ett lämpligt experiment för sådana här mätningar eftersom det är ett högpresicionsexperiment och har dessutom samlat in stora mängder data av hyperon-antihyperonpar. Målet för detta projekt har varit att studera de statistiska precisioner av fysikparametrar som kan nås när man använder den nya metoden i de fall där J/ψ mesonen sönderfaller till ΛΛ, Σ+Σ− och Σ0Σ0. Hög statistisk precision behövs för att upptäcka CP-brott, eftersom CP-brytande processer, om de existerar, är relativt sällsynta. Huvudfokuset var att studera processen e+e− → J/ψ → Σ0Σ0 → ΛγΛγ → pπ−γpπ+γ. I denna process kan CP-symmetri testas för två sönderfallsprocesser: det elektromagnetiska sönderfallet Σ0 → Λγ och det svaga sönderfallet Λ → pπ−. I denna rapport studerades bara asymmetriparametrarna av Λ → pπ−. Detta arbete har fungerat som validitetskontroll av den nya metoden och pågående analyser på BESIII. Den statistiska precisionen undersöktes med simuleringar: Monte Carlo datamängder skapades och sedan en maximum-log-likelihood-anpassning av datan genomfördes. En viktig komponent i bestämningen av asymmetriparametrarna visade sig vara den relativa fasen, ∆φJ/ψ. Den relativa fasen är en av de parametrar som används för att bestämma relationen mellan de elektriska och magnetiska formfaktorer. ∆φJ/ψ är också relaterad till hyperonens hyperon-antihyperonparets polarisation. I forskningsprojektet visades att ∆φJ/ψ har en stor inverkan på osäkerheterna av hyperon- och antihyperonasymmetriparametrarna. Ett lågt värde av ∆φJ/ψ resulterade i stora osäkerheter och starka korrelationer mellan asymmetriparametrarna. Formalismen är annorlunda för olika processer, vilket också påverkar osäkerheterna. Formalismen som används för Σ0Σ0-processen ger sämre parameterprecision av asymmetriparametern kopplad till sönderfallet Λ → pπ− än formalismen som används för ΛΛ-processen. Därför är ΛΛ-processen en mycket lämpligare process för att testa CP-symmetrin i Λ → pπ− sönderfallet.

Abstract:

I denna litteraturstudie granskades 4 vetenskapliga artiklar med syfte att undersöka patienters upplevelser av hyperbar oxygenbehandling (HBO behandling) för att lyfta fram vad man som omvårdnadspersonal bör ha i åtanke inför initiala behandlingar. HBO behandling är en behandlingsmetod där koncentrerad oxygen administreras till patienter. Behandling med HBO får ofta pågå under längre tid för att uppnå läkande effekter i exempelvis fall av hypoxiska svårläkta sår. Ett av de initiala problem som kan ge obehagskänslor är att behandlingen tar plats i tryckkammare, vilket för många är en främmande miljö. Flertalet patienter har av denna anledning valt att avstå ifrån behandling. Inför behandling är även oro vanligt hos omkring hälften av tillfrågade patienter. Väl under behandling beskrivs tristess och ovissheten av behandlingens resultat som problem. Fortsatta studier om HBO behandling skulle kunna öka kunskapen om patienters upplevelser och eventuell oro. Denna kunskap skulle i sin tur omvårdnadspersonalen kunna använda för att genom omvårdnadshandling minska eventuella obehag av HBO behandling.

Abstract:

Zur Erforschung des Verhaltens der Kernmaterie wurde mit dem Dielektronen-Spektrometer HADES am GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt unter anderem die Reaktion p + Nb bei 3,5 GeV kinetischer Strahlenergie untersucht. Obwohl HADES primär für den Nachweis seltener leptonischer Zerfälle der Vektormesonen ρ, ω und φ konzipiert wurde, eignet sich das Spektrometer aufgrund seiner präzisen Spurrekonstruktion auch für die Untersuchung von hadronischen Kanälen. Zum Studium der Strangeness-Signaturen in der Reaktion p + Nb wird in dieser Arbeit der im Jahr 2008 aufgezeichnete Datensatz von ca. 4,2 Milliarden Kollisionen hinsichtlich der Produktion und der dabei auftretenden Polarisation von Λ-Hyperonen untersucht. Die polarisierte Produktion von Hyperonen in Kernreaktionen mit unpolarisierten Ausgangsteilchen wurde entgegen den theoretischen Erwartungen erstmals 1976 beobachtet und fand bis heute keine allgemein akzeptierte und alle beobachteten Abhängigkeiten umfassende Erklärung auf Grundlage der starken Wechselwirkung. Es werden zunächst die theoretischen Modelle der Hyperonpolarisation diskutiert und der experimentelle Zugang erklärt. Dieser gelingt über den schwachen Zerfall des Λ-Hyperons, der als natürliches Polarimeter wirkt und somit insbesondere in Reaktionen mit unpolarisierten Nukleonen ein ideales Instrument zur Untersuchung der Polarisation darstellt. Aufgrund der großen Raumwinkelabdeckung ermöglicht HADES, Λ-Hyperonen in einem weiten Phasenraumbereich zu rekonstruieren, sodass deren Produktionsrate und Polarisation in Abhängigkeit der Observablen Transversalimpuls pt und Rapidität y analysiert werden. Aus insgesamt 1,1 Millionen rekonstruierten Λ-Hyperonen werden nach der Korrektur bezüglich der Detektorakzeptanz und -effizienz transversale Massenspektren extrahiert. Deren inverser Steigungsparameter TB (y) nimmt ein Maximum von rund 90 MeV bei y = 1, d.h. unterhalb der Schwerpunktsrapidität im Nukleon-Nukleon-Stoß (ycm = 1,12), an und fällt zu kleinen Rapiditäten deutlich schneller ab als für Teilchen im thermischen Gleichgewicht. Die Λ-Rapiditätsdichte zeigt eine asymmetrische Verteilung, die aufgrund von Mehrfachstreuung der Λ-Hyperonen hauptsächlich mit Kern-Nukleonen deutlich zur Targetrapidität verschoben ist und mit steigender Rapidität > 0,3 stark abnimmt. Auf den vollständigen Phasenraum extrapoliert, erfüllt die Produktionsrate von 0,018 ± 0,004 Λ-0 Hyperons je Ereignis, verbunden mit der Multiplizität von Ks -Mesonen und den mittels Transportmodell abgeleiteten Produktionsverhältnissen zu den übrigen Kaonen und Hyperonen, die Strangeness-Erhaltung im Mittel der gemessenen Kollisionen. Darüber hinaus zeigt das Λ-Hyperon eine signifikant negative Polarisation relativ zur Normalen seiner Produktionsebene, die über den verfügbaren Phasenraum gemittelt Px = (−10,6 ± 1,3) % beträgt und deren Betrag mit steigendem Transversalimpuls entsprechend Px (pt ) = (−0,19 ± 0,02) (GeV/c)−1 pt linear zunimmt. Die Ergebnisse bezüglich der Λ-Polarisation und Phasenraumverteilung werden mit denen anderer Experimente ähnlicher Stoßsysteme verglichen und im Rahmen von systematischen Untersuchungen mit Transportmodellen interpretiert, um Details zur Dynamik der Hyperon-Produktion in Proton-Kern-Reaktionen abzuleiten. Derzeit verfügbare Versionen der GiBUU- und UrQMD-Modelle können die experimentellen Verteilungen im Phasenraum jedoch nicht hinreichend reproduzieren. Mit der Rekonstruktion von Ξ− -Hyperonen und φ-Mesonen wird ein Ausblick auf weiterführende Studien zur Strangeness-Produktion in Nukleon-Kern-Stößen gegeben
With the dielectron spectrometer HADES, located at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, p + Nb reactions at a kinetic beam energy of 3.5 GeV were measured to study the behavior of nuclear matter. Although primarily designed for the detection of rare leptonic decays of the light vector mesons ρ, ω and φ, the spectrometer renders itself very well suited for the investigation of hadrons, due to its excellent tracking capability. This thesis presents results of the production and polarization of strange Λ hyperons in about 4.2 billion reactions of p + Nb recorded in 2008. In contrast to theoretical expectations, the polarized production of hyperons was observed in 1976 for the first time in nuclear reactions with unpolarized beams. Based on the fundamental properties of strong interaction, to date no single explanation exists describing all dependencies of the observed hyperon polarization. Therefore, common theoretical models of hyperon polarization are introduced. Acting as a natural polarimeter, the Λ hyperon represents an excellent tool to study the phenomenon of hyperon polarization especially in reactions with unpolarized beams and targets. Hence, the experimental technique for extracting the polarization using the weak decay of the Λ hyperon is explained. Due to a large solid angle coverage, HADES allows for the reconstruction of hadrons within a wide phase space range. Consequently, a double-differential analysis of the polarization and production probability as a function of transverse momentum pt and rapidity y is performed. In total, 1.1 million Λ hyperons are reconstructed and corrected for detector acceptance and efficiency. The inverse slope parameter TB is extracted from transverse mass spectra. Its rapidity dependence TB (y) shows a maximum of 90 MeV at y = 1, i.e. below the center-of-mass rapidity of the nucleon-nucleon collision ycm = 1.12, and a stronger decrease to lower rapidities than particles in thermal equilibrium. The Λ rapidity density shows an asymmetric distribution, shifted towards target rapidity, which is probably caused by multiple scattering on target nucleons. Extrapolated to the full phase space, the total multiplicity of 0.018 ± 0.004 Λ hyperons per event satisfies strangeness conservati- 0 on on average. For that purpose, the Ks production rate from another analysis and ratios to the other, unmeasured, strange hadrons, derived from transport simulations, are taken into account. Furthermore, the Λ hyperon shows a significant negative polarization perpendicular to its production plane, which amounts to Px = (−10.6 ± 1.3) % averaged over the phase space accessible to HADES. The measured Λ polarization increases almost linearly with increasing transverse momentum pt , according to Px (pt ) = (−0.19 ± 0.02) (GeV/c)−1 pt . In order to spot details on the dynamics of hyperon production in proton-nucleus reactions, the results on Λ polarization and phase space distribution are compared to those of similar reactions. Additionally, a systematic investigation with transport model simulations is performed. The experimental distributions can not be reproduced sufficiently well by the presently available GiBUU and URQMD models. Moreover, an outlook on further studies of strangeness production in nucleon-nucleus collisions by reconstruction of Ξ− hyperons and φ mesons is given
