Título: Analizando la influencia del tiempo de juego y puntuación parcial en el comportamiento táctico en el duelo 2 vs 2 en el proceso ofensivo en balonmano, utilizando la técnica de coordenadas polares. Resumen: Diferentes estudios hacen referencia a como el tiempo de juego, la puntuación parcial y la interacción de ambos influyen en los comportamientos de jugadores y equipos. Con este estudio se intentó demostrar la compleja realidad del comportamiento táctico en el ataque en la Copa de Europa Masculina, mediante la detección de patrones de comportamiento y vincularlos al tiempo de juego y a la puntuación parcial. Se utilizó metodología observacional, y para el análisis de los datos se utilizó la técnica de coordenadas polares. El instrumento de observación fue construido ad hoc y validado. La optimización de la herramienta incluye el control de calidad del dato, mediante el análisis de la fiabilidad del observador intra e inter a través del índice Kappa de Cohen (rango entre .85 y 1), y la aplicación del análisis de generalizabilidad (los índices G son adecuados para todos los modelos estimados) que confirman la fiabilidad del instrumento. La muestra contenía todas las situaciones de 2vs2 que se produjeron durante el proceso de ataque organizadas en igualdad numérica 6vs6, en dieciséis partidos (n = 390). Como principales resultados se pueden referir que el tiempo de juego influyó en la toma de decisiones en relación con los medios tácticos empleados, a excepción de los últimos diez minutos, donde no se encontraron patrones. Los resultados también muestran que hay un menor número de patrones de comportamiento cuando el marcador es un empate. Palabras-clave: Metodologia Observacional; Coordenadas polares; Comportamiento táctico; Análisis del rendimiento; Balonmano. Abstract: Different studies have referred that the playing time and partial score, as well as the interaction between these two influences the behaviors of players and teams. With this study we intended to realize the complex reality of tactical behavior in the attack in Men ́s European Cup, by detecting behavior patterns and linking them to playing time and partial score. We used the observational methodology and for data analysis we used the polar coordinates. An instrument of observation has been constructed ad hoc and validated. The tool optimization included the quality data control, using the analysis of intra and inter observer reliability by Cohen's Kappa index (range between .85 and 1), beyond the application of generalizability analysis (G indexes are suitable for all models estimated) confirming the instrument reliability. The sample contained all of 2vs2 situations that occurred during the organized offensive process in numerical equality 6vs6, in sixteen games (n = 390). As main results we can refer that the playing time influenced the decisionmaking in relation to the tactical means used, excepting the last ten minutes, where no patterns were found. The results also show that there are fewer behavior patterns when the score is a draw.

In this paper, the Elzaki transform method is used for solving two-dimensional (2D) elasticity problems in plane polar coordinates. Airy stress function was used to express the stress compatibility equation as a biharmonic equation. Elzaki transform was applied with respect to the radial coordinate to a modified form of the stress compatibility equation, and the biharmonic equation simplified t...
