Factors Affecting Capital Structure and Stock Prices of Agricultural and Mining Companies

The purpose of this study was to analyze the influence of business risk, asset growth, sales growth, earning per share, and asset structure to capital structure and share price. This study involved mining and agriculture companies listed on IDX within the period of 2010-2017. The analysis employed eViews 9. Based on the hypothesis testing, it was found that that business risk, sales growth, and asset structure do not have a significant effect on capital structure. However, asset growth has a significant influence. Furthermore, sales growth and EPS do not have a significant effect on share price, but the asset structure has a significant influence. This research is a development of previous research by adding earnings per share as an independent variable and covering the period 2010 - 2017 in order to show the most actual conditions. Company management can make the results of this study a consideration in determining the optimal capital structure.   This study only examined the mining and agricultural sectors on the Indonesian stock exchange

Synthetic synchrotron emission maps from MHD models for the jet of M87

We present self-consistent global, steady-state MHD models and synthetic optically thin synchrotron emission maps for the jet of M87. The model consist of two distinct zones: an inner relativistic outflow, which we identify with the observed jet, and an outer cold disk-wind. While the former does not self-collimate efficiently due to its high effective inertia, the latter fulfills all the conditions for efficient collimation by the magneto-centrifugal mechanism. Given the right balance between the effective inertia of the inner flow and the collimation efficiency of the outer disk wind, the relativistic flow is magnetically confined into a well collimated beam and matches the measurements of the opening angle of M87 over several orders of magnitude in spatial extent. The synthetic synchrotron maps reproduce the morphological structure of the jet of M87, i.e. center-bright profiles near the core and limb-bright profiles away from the core. At the same time, they also show a local increase of brightness at some distance along the axis associated to a recollimation shock in the MHD model. Its location coincides with the position of the optical knot HST-1. In addition our best fitting model is consistent with a number of observational constraints such as the magnetic field in the knot HST-1, and the jet-to-counterjet brightness ratio.Comment: 9 pages, 9 figures, accepted by Ap

Fast Fight Detection

Action recognition has become a hot topic within computer vision. However, the action recognition community has focused mainly on relatively simple actions like clapping, walking, jogging, etc. The detection of specific events with direct practical use such as fights or in general aggressive behavior has been comparatively less studied. Such capability may be extremely useful in some video surveillance scenarios like prisons, psychiatric centers or even embedded in camera phones. As a consequence, there is growing interest in developing violence detection algorithms. Recent work considered the well-known Bag-of-Words framework for the specific problem of fight detection. Under this framework, spatio-temporal features are extracted from the video sequences and used for classification. Despite encouraging results in which high accuracy rates were achieved, the computational cost of extracting such features is prohibitive for practical applications. This work proposes a novel method to detect violence sequences. Features extracted from motion blobs are used to discriminate fight and non-fight sequences. Although the method is outperformed in accuracy by state of the art, it has a significantly faster computation time thus making it amenable for real-time applications

QED in external fields from the spin representation

Systematic use of the infinite-dimensional spin representation simplifies and rigorizes several questions in Quantum Field Theory. This representation permutes ``Gaussian'' elements in the fermion Fock space, and is necessarily projective: we compute its cocycle at the group level, and obtain Schwinger terms and anomalies from infinitesimal versions of this cocycle. Quantization, in this framework, depends on the choice of the ``right'' complex structure on the space of solutions of the Dirac equation. We show how the spin representation allows one to compute exactly the S-matrix for fermions in an external field; the cocycle yields a causality condition needed to determine the phase.Comment: 32 pages, Plain TeX, UCR-FM-01-9

ARTHUR’S HEIRS: SITUATING MEDIEVAL WELSH, SPANISH, AND SCANDINAVIAN TEXTS IN THEIR LITERARY AND HISTORICAL CONTEXTS

This dissertation addresses a significant gap in Arthurian scholarship by adapting postcolonial and translation theory to analyze Medieval Arthurian literature from the peripheral cultures that interacted throughout the Irish Sea and the Atlantic littoral. This project uses a similar approach as that traditionally employed in Mediterranean studies to investigate Arthurian texts and related materials from the Celtic (Irish and Welsh), Scandinavian (Norwegian and Icelandic), and Iberian (Castilian and Catalan) cultural peripheries to point out both the local and transcultural roles of these texts. By highlighting that Arthurian literature was not only transmitted from Britain through France to the rest of Europe, but was instead produced and read through a Pan-European network, it is demonstrated that Medieval Arthurian literature is a product of the multicultural interactions that shaped medieval Europe. Moreover, a focus on the relationship between kings and their subjects, both male and female, becomes a medium to interrogate the function Arthurian stories played in differing constructions of sovereignty. In order to understand that relationship, it is necessary to analyze these Arthurian texts through their different cultural and historical contexts and how they were shaped by and in turn shaped their environments

On the ultraviolet behaviour of quantum fields over noncommutative manifolds

By exploiting the relation between Fredholm modules and the Segal-Shale-Stinespring version of canonical quantization, and taking as starting point the first-quantized fields described by Connes' axioms for noncommutative spin geometries, a Hamiltonian framework for fermion quantum fields over noncommutative manifolds is introduced. We analyze the ultraviolet behaviour of second-quantized fields over noncommutative 3-tori, and discuss what behaviour should be expected on other noncommutative spin manifolds.Comment: 10 pages, RevTeX version, a few references adde
