Story beats in videogames as value-driven choice-based unit operations
2021
We present a framework of story beats, defined as microunits of dramatic action, as a tool for the ludonarrative analysis of videogames. First, we explain the Goal - Action - Reaction - Outcome model of the story beat. Then, we present six types of story beats, Action, Interaction, Inaction, Mental, Emotion, and Sensory, providing videogame examples for each category. In the second half of the paper, we contextualise this framework in the classic game studies theory of videogame narrative and player action: unit operations, gamic action, anatomy of choice, and game design patterns, wrapping it up in the most recent trends in cognitive narratology. Ultimately, we present the story beat as a …
A Complete, Exact and Efficient Implementation for Computing the Edge-Adjacency Graph of an Arrangement of Quadrics
2011
International audience; We present a complete, exact and efficient implementation to compute the edge-adjacency graph of an arrangement of quadrics, i.e. surfaces of algebraic degree 2. This is a major step towards the computation of the full 3D arrangement. We enhanced an implementation for an exact parameterization of the intersection curves of two quadrics, such that we can compute the exact parameter value for intersection points and from that the edge-adjacency graph of the arrangement. Our implementation is complete in the sense that it can handle all kinds of inputs including all degenerate ones, i.e. singularities or tangential intersection points. It is exact in that it always comp…
Single Event Upsets Induced by Direct Ionization from Low-Energy Protons in Floating Gate Cells
2017
Floating gate cells in advanced NAND Flash memories, with single-level and multi-level cell architecture, were exposed to low-energy proton beams. The first experimental evidence of single event upsets by proton direct ionization in floating gate cells is reported. The dependence of the error rate versus proton energy is analyzed in a wide energy range. Proton direct ionization events are studied and energy loss in the overlayers is discussed. The threshold LET for floating gate errors in multi-level and single-level cell devices is modeled and technology scaling trends are analyzed, also discussing the impact of the particle track size. peerReviewed
Expressions multiplicatives en textos catalans medievals
2015
Explicitació i aclariment de passatges amb expressions multiplicatives en textos medievals en català: (1) "Estar en quatre tants" (Facet); (2) "A cent doblàries" (Vita Christi d'Isabel de Villena); (3) "Doble és l'afany" (poema 1 d'Ausiàs March). An explicitation and clarification of three medieval Catalan texts' passages with multiplicative expressions: (1) "Estar en quatre tants" (Facet); (2) "A cent doblàries" (Vita Christi by Isabel de Villena); (3) "Doble és l'afany" (Ausiàs March, poem 1).
Testing and implementing a new approach to estimating interregional output multipliers using input-output data for South Korean regions
2020
Flegg's location quotient (FLQ) is a useful tool for estimating intraregional output multipliers. This paper uses it as one component when estimating interregional multipliers. Using statistical information criteria and official data for 16 South Korean regions, it is found that the best approach is to combine the FLQ with a simple trade model. The paper explains how the proposed procedure can be implemented for both multiple and individual regions, and also how a region-specific value for the unknown parameter δ in the FLQ formula can be determined. Finally, an illustrative case study of one of the regions is carried out.
Self-regulated learning, self-efficacy beliefs and performance during the late childhood
2010
This article analyzes relations between self-regulated learning, self-efficacy beliefs, and performance in tasks of solving arithmetic problems. The research includes 268 six-year-old students enrolled in the first year of primary school in Spain. The results from binary logistic regression models indicate that self-regulated learning and its interaction with self-efficacy beliefs predict performance. Finally, the cluster analysis shows four profiles of students: i) positive adjusted; ii) negative unadjusted I; iii) negative unadjusted II y; iv) negative adjusted.. Este artículo analiza relaciones entre el aprendizaje autorregulado, las creencias de autoeficacia y el desempeño en tareas de …
Broglie and Young, visionaries who shed light in the polar topology that grounds our reality: a hypothesis
2020
Una observación matemática que relaciona los patrones fractales y la operación de convolución en el contexto del procesamiento de imágenes digitales interrumpió una investigación que nos lleva a plantear la hipótesis de que el concepto de onda de materia (o dualidad onda-partícula) se encuentra en la dicotomía entre el par débil y un topología fuerte en el ámbito del marco de atractores singulares continuos en ninguna parte diferenciables y el concepto de fotón-solitón de Vigier. Tal inferencia parece ser más evidente en la interpretación de Broglie-Bohm de la mecánica cuántica en el cruce de características locales x globales. De esto se deduce también que la relación de los fenómenos natu…
THE ARITHMETIC BOHR RADIUS
2007
We study the arithmetic Bohr radius of Reinhardt domains in ℂ n which was successfully used in our study of monomial expansions for holomorphic functions in infinite dimensions. We show that this new Bohr radius is different from the radii invented by Boas and Khavinson and Aizenberg. It gives an explicit formula for the n-dimensional hypercone (which means n-dimensional variants of classical results of Bohr and Bombieri), and moreover asymptotically corrects upper and lower estimates for various types of convex and non-convex Reinhardt domains.
Arithmetic, Logic, Syntax and MathCheck
2019
MathCheck is a web-based tool for checking all steps of solutions to mathematics, logic and theoretical computer science problems, instead of checking just the final answers. It can currently deal with seven problem types related to arithmetic, logic, and syntax. Although MathCheck does have some ability to perform symbolic computation, checking is mostly based on testing with many combinations of the values of the variables in question. This introduces a small risk of failure of detection of errors, but also significantly widens the scope of problems that can be dealt with and facilitates providing a concrete counter-example when the student’s solution is incorrect. So MathCheck is primari…
Reliable Outer Bounds for the Dual Simplex Algorithm with Interval Right-hand Side
2013
International audience; In this article, we describe the reliable computation of outer bounds for linear programming problems occuring in linear relaxations derived from the Bernstein polynomials. The computation uses interval arithmetic for the Gauss-Jordan pivot steps on a simplex tableau. The resulting errors are stored as interval right hand sides. Additionally, we show how to generate a start basis for the linear programs of this type. We give details of the implementation using OpenMP and comment on numerical experiments.
