description: The climatic variability significantly impacts agricultural sustainability and food security. This study aimed to evaluate climate variability and its relationship with coconut production in the canton of Strong Rock. The production system was analyzed using an exploratory approach with stratified random sampling, dividing the canton into two strata: the upper area "El Cardón" and the lower area "El Pasaje". Seven production parameters were analyzed through surveys, and two meteorological stations were installed, one in each zone. Daily data on precipitation, temperature, humidity, and evapotranspiration were collected for six months (January – June 2024) and statistically analyzed using Pearson correlation. The data were compared with NASA's 12-year historical records starting in 2010. The most produced variety was manion, yielding 846.1 kg/m² in "El Cardón" and 297.8 kg/m² in "El Pasaje." Evapotranspiration and temperature had a high positive correlation with coconut production (0.78 in "El Cardón" and 0.82 in "El Pasaje"), while humidity and precipitation had a low negative correlation. The meteorological data closely matched NASA's historical values for June. The study shows that climatic variability affects coconut production parameters related to flowering and fruiting in the studied areas.

Subjects: subject: Neural and Evolutionary Computing (cs.NE)

description: One of the problems in applying Genetic Algorithm is that there is some situation where the evolutionary process converges too fast to a solution which causes it to be trapped in local optima. To overcome this problem, a proper diversity in the candidate solutions must be determined. Most existing diversity-maintenance mechanisms require a problem specific knowledge to setup parameters properly. This work proposes a method to control diversity of the population without explicit parameter setting. A self-adaptation mechanism is proposed based on the competition of preference characteristic in mating. It can adapt the population toward proper diversity for the problems. The experiments are carried out to measure the effectiveness of the proposed method based on nine well-known test problems. The performance of the adaptive method is comparable to traditional Genetic Algorithm with the best parameter setting.

description: We propose a general method for automated word puzzle generation. Contrary to previous approaches in this novel field, the presented method does not rely on highly structured datasets obtained with serious human annotation effort: it only needs an unstructured and unannotated corpus (i.e., document collection) as input. The method builds upon two additional pillars: (i) a topic model, which induces a topic dictionary from the input corpus (examples include e.g., latent semantic analysis, group-structured dictionaries or latent Dirichlet allocation), and (ii) a semantic similarity measure of word pairs. Our method can (i) generate automatically a large number of proper word puzzles of different types, including the odd one out, choose the related word and separate the topics puzzle. (ii) It can easily create domain-specific puzzles by replacing the corpus component. (iii) It is also capable of automatically generating puzzles with parameterizable levels of difficulty suitable for, e.g., beginners or intermediate learners.

description: The thesis is devoted to the investigation of the diversity of type Ia supernovae (SNe) progenitors. First of all we present an analysis of the height distributions of the different types of SNe from the plane of their host galaxies. We use a well-defined sample of 102 nearby SNe appearing inside high-inclined (i ≥ 85 deg), morphologically non-disturbed S0-Sd host galaxies from the Sloan Digital Sky Survey. Then, in the next chapter, using spectroscopically classified normal, 91T-, and 91bg-like 197 SNe Ia, we perform an analysis of their height distributions from the disc in edge-on spirals and investigate their light-curve (LC) decline rates (∆m15).After this, we present an analysis of the LC decline rates of 407 normal and peculiar SNe Ia and global parameters of their host galaxies. Next, we perform an analysis of the galactocentric distributions of the normal and peculiar 91bg-like subclasses of 109 SNe Ia, and study the global parameters of their elliptical hosts.To perform various comparisons between the properties/numbers of the different subsamples, we use the well-known statistical tests (Kolmogorov-Smirnov and Anderson-Darling tests, etc.) with the implementation of the WOLFRAM MATHEMATICA software and Monte Carlo simulations. In addition to the mentioned tests, we use the Kendall's and Spearman's rank coefficients/tests to analyse the possible correlations between the physical (intrinsic) properties of SNe Ia (subclass, ∆m15, etc.) and their host galaxies (stellar mass, age, etc.).Our investigation of SNe Ia LC decline rates at different locations within their host galaxies aided in distinguishing between SNe Ia with young progenitors (slow-decliners), corresponding to the "prompt" component with short delay times, and those (fast-decliners) with "older" components exhibiting long delay times. The observational findings are in line with the SN Ia explosion models involving a sub-MCh mass white dwarf, where the SN LC decline rate serves as a suitable indicator of progenitor population age.

description: I review recent works on the symmetry and the structure of the superconducting gap in Fe-based superconductors and on the underlying pairing mechanism in these systems. The experimental data on superconductivity show very rich behavior, with potentially different symmetry of a superconducting state for different compositions of the same material. The variety of different pairing states raised the issue whether the physics of Fe-based superconductors is model-dependent or is universal, governed by a single underlying pairing mechanism. I argue that the physics is universal and that all pairing states obtained so far can be understood within the same universal pairing scenario and are well described by the effective low-energy model with a small number of input parameters.

Competitive Coevolution through Evolutionary Complexification

description: Two major goals in machine learning are the discovery and improvement of solutions to complex problems. In this paper, we argue that complexification, i.e. the incremental elaboration of solutions through adding new structure, achieves both these goals. We demonstrate the power of complexification through the NeuroEvolution of Augmenting Topologies (NEAT) method, which evolves increasingly complex neural network architectures. NEAT is applied to an open-ended coevolutionary robot duel domain where robot controllers compete head to head. Because the robot duel domain supports a wide range of strategies, and because coevolution benefits from an escalating arms race, it serves as a suitable testbed for studying complexification. When compared to the evolution of networks with fixed structure, complexifying evolution discovers significantly more sophisticated strategies. The results suggest that in order to discover and improve complex solutions, evolution, and search in general, should be allowed to complexify as well as optimize.

description: Die Termintreue ist eine der wichtigsten logistischen Zielgrößen in der Produktion. Vielen Unternehmen fällt es jedoch schwer, die Termintreue systematisch zu steuern. Ob eine Fertigung ihre Aufträge termintreu fertigstellt, hängt vom Rückstand und der Reihenfolgeabweichung ab. Die in dieser Arbeit entwickelte Modellierung der Termintreue in Abhängigkeit von ihren Einflussgrößen deckt die Ursachen mangelhafter Termintreue auf und ermöglicht zielgerichtete Veränderungen zur ihrer Verbesserung.
description: Schedule reliability is one of the most important logistic targets in operations management. Many companies struggle to control their schedule reliability systematically. Whether a production facility is able to complete its jobs on time depends on the backlog and the sequence deviations within the production flow. This work models schedule reliability as a function of its influencing variables. The model helps to detect the sources of low schedule reliability and provides starting points to increase it.

description: The simple reflection of a light beam of finite transverse extent from a homogenous interface gives rise to a surprisingly large number of subtle shifts and deflections which can be seen as diffractive corrections to the laws of geometrical optics [Goos-Hänchen shifts] and manifestations of optical spin-orbit coupling [Imbert-Fedorov shifts], related to the spin Hall effect of light. We develop a unified linear algebra approach to dielectric reflection which allows for a simple calculation of all of these effects and lends itself to an interpretation of beam shifts as weak values in a classical analogue to a quantum weak measurement. We present a systematic study of the shifts for the whole beam and its polarization components, finding symmetries between input and output polarizations and predicting the existence of material independent shifts.

description: Understanding how contagions (information, infections, etc) are spread on complex networks is important both from practical as well as theoretical point of view. Considerable work has been done in this regard in the past decade or so. However, most models are limited in their scope and as a result only capture general features of spreading phenomena. Here, we propose and study a model of spreading which takes into account the strength or quality of contagions as well as the local (probabilistic) dynamics occurring at various nodes. Transmission occurs only after the quality-based fitness of the contagion has been evaluated by the local agent. The model exhibits quality-dependent exponential time scales at early times leading to a slowly evolving quasi-stationary state. Low prevalence is seen for a wide range of contagion quality for arbitrary large networks. We also investigate the activity of nodes and find a power-law distribution with a robust exponent independent of network topology. Our results are consistent with recent empirical observations.

description: When writing a constraint program, we have to choose which variables should be the decision variables, and how to represent the constraints on these variables. In many cases, there is considerable choice for the decision variables. Consider, for example, permutation problems in which we have as many values as variables, and each variable takes an unique value. In such problems, we can choose between a primal and a dual viewpoint. In the dual viewpoint, each dual variable represents one of the primal values, whilst each dual value represents one of the primal variables. Alternatively, by means of channelling constraints to link the primal and dual variables, we can have a combined model with both sets of variables. In this paper, we perform an extensive theoretical and empirical study of such primal, dual and combined models for two classes of problems: permutation problems and injection problems. Our results show that it often be advantageous to use multiple viewpoints, and to have constraints which channel between them to maintain consistency. They also illustrate a general methodology for comparing different constraint models.

description: We report x-ray diffraction, electrical resistivity, and magnetoresistance measurements on Bi2Se3 under high pressure and low temperature conditions. Pressure induces profound changes in both the room temperature value of the electrical resistivity as well as the temperature dependence of the resistivity. Initially, pressure drives Bi2Se3 towards increasingly insulating behavior and then, at higher pressures, the sample appears to enter a fully metallic state coincident with a change in the crystal structure. Within the low pressure phase, Bi2Se3 exhibits an unusual field dependence of the transverse magnetoresistance that is positive at low fields and becomes negative at higher fields. Our results demonstrate that pressures below 8 GPa provide a non-chemical means to controllably reduce the bulk conductivity of Bi2Se3.

description: We present the mass function of supermassive black holes (SMBHs) over the redshift range z=0-2, using the latest deep luminosity and mass functions of field galaxies to constrain the masses of their spheroids, which we relate to SMBH mass through the empirical correlation between SMBH and spheroid mass (the M_bh-M_sph relation). In ddition to luminosity fading of the stellar content of the spheroids, we carefully consider the variation of the bulge-to-total luminosity ratio of the galaxy populations and the M_bh/M_sph ratio, which, according to numerous recent studies, evolves rapidly with redshift. The SMBH mass functions derived from the galaxy luminosity and mass functions show very good agreement, both in shape and in normalization. The resultant SMBH mass function and integrated mass density for the local epoch (z~0) match well those derived independently by other studies. Consistent with other evidence for cosmic downsizing, the upper end of the mass function remains roughly constant since $z\approx2$, while the space density of lower mass black holes undergoes strong evolution. We carefully assess the impact of various sources of uncertainties on our calculations. A companion paper uses the mass function derived in this work to determine the radiative efficiency of black hole accretion and constraints that can be imposed on the cosmological evolution of black hole spin.

Wheel Rail Interaction Modeling on Rail Vehicle System Lateral Dynamics
Creators: name: Birhan Abebaw
Publisher: name: Zenodo
Year: 2014

description: The long history of railway engineering provides many practical examples of dynamic

problems which are unique to railway vehicles. One of the railway vehicle's dynamic

problems is the lateral dynamic which is mainly arising from wheel rail contact

condition. In the early time, to analyze and formulate such kinds of railway vehicle

dynamics scientists had been using different experimental methods such as roller rigs

and roller coasters. Even though such experimental methods are most efficient and

error free, they are very costly and need some time. But now a day there are different

computer packages used to study and simulate the dynamic behavior of a railway

vehicle (ADAMS/RAIL, SIMPAKC and Vampire). These computational packages

are very efficient in both cost and time but they are not more flexible and require indepth

knowledge to run them. So this paper tried to make the computational tool more

flexible and easy to use with basic computer knowledge

description: A system of autonomous differential equations with a stable limit cycle and perturbed by small white noise is analyzed in this work. In the vicinity of the limit cycle of the unperturbed deterministic system, we define, construct, and analyze the Poincare map of the randomly perturbed periodic motion. We show that the time of the first exit from a small neighborhood of the fixed point of the map, which corresponds to the unperturbed periodic orbit, is well approximated by the geometric distribution. The parameter of the geometric distribution tends zero together with the noise intensity. Therefore, our result can be interpreted as an estimate of stability of periodic motion to random perturbations. In addition, we show that the geometric distribution of the first exit times translates into statistical properties of solutions of important differential equation models in applications. To this end, we demonstrate three examples from mathematical neuroscience featuring complex oscillatory patterns characterized by the geometric distribution. We show that in each of these models the statistical properties of emerging oscillations are fully explained by the general properties of randomly perturbed periodic motions identified in this paper.

description: This is the first of three planned papers describing ZAP, a satisfiability engine that substantially generalizes existing tools while retaining the performance characteristics of modern high-performance solvers. The fundamental idea underlying ZAP is that many problems passed to such engines contain rich internal structure that is obscured by the Boolean representation used; our goal is to define a representation in which this structure is apparent and can easily be exploited to improve computational performance. This paper is a survey of the work underlying ZAP, and discusses previous attempts to improve the performance of the Davis-Putnam-Logemann-Loveland algorithm by exploiting the structure of the problem being solved. We examine existing ideas including extensions of the Boolean language to allow cardinality constraints, pseudo-Boolean representations, symmetry, and a limited form of quantification. While this paper is intended as a survey, our research results are contained in the two subsequent articles, with the theoretical structure of ZAP described in the second paper in this series, and ZAP's implementation described in the third.

description: State-of-the-art attosecond metrology deals with the detection and characterization of photon pulses with typical energies up to the hundreds of eV and time resolution of several tens of attoseconds. Such short pulses are used for example to control the motion of electrons on the atomic scale or to measure inner-shell atomic dynamics. The next challenge of time-resolving the inner-nuclear dynamics, transient meson states and resonances requires photon pulses below attosecond duration and with energies exceeding the MeV scale. Here we discuss a detection scheme for time-resolving high-energy gamma ray pulses down to the zeptosecond timescale. The scheme is based on the concept of attosecond streak imaging, but instead of conversion of photons into electrons in a nonlinear medium, the high-energy process of electron-positron pair creation is utilized. These pairs are produced in vacuum through the collision of a test pulse to be characterized with an intense laser pulse, and they acquire additional energy and momentum depending on their phase in the streaking pulse at the moment of production. A coincidence measurement of the electron and positron momenta after the interaction provides information on the pair production phase within the streaking pulse. We examine the limitations imposed by quantum radiation reaction in multiphoton Compton scattering on this detection scheme, and discuss other necessary conditions to render the scheme feasible in the upcoming Extreme Light Infrastructure (ELI) laser facility.

description: In VQ based image compression technique has three major steps namely (i) Codebook Design, (ii) VQ Encoding Process and (iii) VQ Decoding Process. The performance of VQ based image compression technique depends upon the constructed codebook. A widely used technique for VQ codebook design is the Linde-Buzo-Gray (LBG) algorithm. However the performance of the standard LBG algorithm is highly dependent on the choice of the initial codebook. In this paper, we have proposed a simple and very effective approach for codebook initialization for LBG algorithm. The simulation results show that the proposed scheme is computationally efficient and gives expected performance as compared to the standard LBG algorithm.

description: Die vorliegende Arbeit entwickelt eine Methode zur Analyse und Verbesserung der Arbeitsproduktivität in der Unikatproduktion. Das zentrale Element ist die Modellierung der bezahlten Arbeitszeit. Dabei beschreiben Mitarbeiterzustände mit Tätigkeiten und Objekten die bezahlte Arbeitszeit umfassend. Die Gliederung in Phasen eines generischen Arbeitszyklus ist die Grundlage, um wiederholbare Produktivitätsgewinne zu ermöglichen. In der Regel erfolgt die Datenerhebung mit einem mehrdimensionalen Multimoment-Häufigkeitsverfahren. Auf Grundlage der Analyseergebnisse können Verbesserungsmaßnahmen zielgerichtet ausgewählt werden.
description: This thesis develops a method for the analysis and improvement of labor productivi-ty in one-of-a-kind productions. The central element is the modeling of the paid working time with activities and objects. The classification into phases of a generic work cycle allows repeatable productivity gains. A multi-dimensional work sam-pling is the standard for the data acquisition. Based on the results, improvement ac-tivities can be systematically selected.

description: Studies of the diffuse X-ray emitting gas in galaxy clusters have provided powerful constraints on cosmological parameters and insights into plasma astrophysics. However, measurements of the faint cluster outskirts have become possible only over the last few years. Here, we present results from Suzaku observations of the Perseus Cluster, which provide our best measurements of the thermodynamic properties of the ICM at large radii to date. In particular, we focus on the details of the data analysis procedure and discuss the evidence for a clumpy distribution of the gas in the outskirts, which is important for understanding the physics of the ongoing growth of clusters from the surrounding cosmic web.

description: Premise: Daffodils (Narcissus, Amaryllidaceae) are iconic ornamentals with a complex floral biology and many fragrant species; however, little is known about floral plant volatile organic compounds (pVOCs) across the genus and additional sampling is desirable. The present study investigates whether the floral scent of 20 species of Narcissus can be characterized using gas chromatography–coupled ion mobility spectrometry (GC–IMS), with the aim of building a comparative pVOC data set for ecological and evolutionary studies. Methods: We used a commercial GC–IMS equipped with an integrated in-line enrichment system for a fast, sensitive, and automated pVOC analysis. This facilitates qualitative and (semi)-quantitative measurements without sample preparation. Results: The GC–IMS provided detailed data on floral pVOCs in Narcissus with very short sampling times and without floral enclosure. A wide range of compounds was recorded and partially identified. The retrieved pVOC patterns showed a good agreement with published data, and five “chemotypes” were characterized as characteristic combinations of floral volatiles. Discussion: The GC–IMS setup can be applied to rapidly generate large amounts of pVOC data with high sensitivity and selectivity. The preliminary data on Narcissus obtained here indicate both considerable pVOC variability and a good correspondence of the pVOC patterns with infrageneric classification, supporting the hypothesis that floral scent could represent a considerable phylogenetic signal.

description: Complex composite films based on polyaniline (PANI) doped hydrochloric acid (HCl) incorporated with aluminum nitrate (Al(NO3)3) on Au-layer were designed and synthesized as a surface plasmon resonance (SPR) sensing device. The physicochemical properties of (PANI-HCl)/Al(NO3)3 complex composite films were studied for various Al(NO3)3 concentrations (0, 2, 4, 8, 16, and 32 wt.%). The refractive index of the (PANI-HCl)/Al(NO3)3 complex composite films increased continuously as Al(NO3)3 concentrations increased. The electrical conductivity values increased from 5.10 µS/cm to 10.00 µS/cm as Al(NO3)3 concentration increased to 32 wt.%. The sensitivity of the SPR sensing device was investigated using a theoretical approach and experimental measurements. The theoretical system of SPR measurement confirmed that increasing Al(NO3)3 in (PANI-HCl)/Al(NO3)3 complex composite films enhanced the sensitivity from about 114.5 [Deg/RIU] for Au-layer to 159.0 [Deg/RIU] for Au-((PANI-HCl)/Al(NO3)3 (32 wt.%)). In addition, the signal-to-noise ratio for Au-layer was 3.95, which increased after coating by (PANI-HCl)/Al(NO3)3 (32 wt.%) complex composite layer to 8.82. Finally, we conclude that coating Au-layer by (PANI-HCl)/Al(NO3)3 complex composite films enhances the sensitivity of the SPR sensing device.
