Motor de videojuegos en C++ sobre SFML
No full text[EN] The purpose of this end-of-degree project report is to
explain some general concepts about video game program-
ming, game engines and their utility, and how X-GSD is
built around some of these ideas, including: types of game
loop and simulation, resource management, scene graph,
entity-component system, events and basic physics.
Nowadays, game engines have become very popular
and a fundamental part for many game developers. De-
spite their bene ts, this tendency comes with costs: As
the most popular engines are proprietary, game developers
become reliant on closed third-party software, which could
lead |among others| to a deadlock of their projects in
the worst case. This and more against-reasons regard-
ing popularity of proprietary and big game engines are
discussed along this work.
X-GSD stands for Cross-platform Game Skeleton (Data-
Driven), a basic data-driven C++ game engine built upon
SFML1. It is a totally free and open basic game engine
which aims to solve some of the problems of proprietary
game engines, or being a starting point for custom solu-
tions. It can also serve as an academic example of how to
start building the core of a game, or a game engine.Ruiz Bernabeu, A. (2015). Motor de videojuegos en C++ sobre SFML. https://riunet.upv.es/handle/10251/53357.TFG
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Sensibilidad de la resistencia a compresión del hormigón con la incertidumbre en la relación agua/cemento de las mezclas
No full textEntre los diferentes parámetros que caracterizan las mezclas de hormigón, la relación agua/cemento (a/c) es la que comúnmente presenta mayor relevancia en la evaluación de numerosas características reológicas y mecánicas. De hecho, de este índice dependen directamente varias características de fundamental importancia entre las que se encuentran la resistencia final a compresión, la trabajabilidad y la durabilidad. En particular, con respecto a la resistencia a compresión y con las evidencias mostradas tanto a nivel de laboratorio como a escala industrial, se acepta que existe una relación funcional entre dicho valor y la relación a/c. Tal relación funcional es comúnmente descrita con unas expresiones de tipo exponencial inversa , hiperbólica o similares. Por otro lado, es bien conocido que baja relaciones a/c inducen elevadas resistencias mecánicas. Sin embargo, no es tan conocida ni estudiada la influencia que las variaciones en la relación a/c respecto al valor nominal, tomado en una planta industrial, pueden dar lugar sobre la resistencia final del hormigón. Asimismo, las dispersiones inevitables de este índice (a/c) respecto al valor nominal de producción son función de varios factores y no siempre es posible controlar con precisión su importancia, sobretodo cuando los análisis de laboratorio se transfieren como datos globales a la producción industrial.
En el presente trabajo, se presenta una aproximación probabilística para valorar el efecto que la incertidumbre en la relación a/c determina sobre los valores de resistencia final a compresión del hormigón
