Riassunto: Sia X un sottoinsieme di r elementi di uno spazio di Hilbert H e sia V0 il sottospazio chiuso generato dall’iterazione di X mediante l’operatore unitario U = (U1, . . . , Ud). Analogamente sia V1 ⊃ V0 il sottospazio generato da un insieme Y con s > r elementi. Si descrivono alcuni metodi per costruire un insieme Γ con s − r elementi che generi in modo simile il complemento ortogonale...

Using the local subgroup strategy of [3] and [4], we classify the radical subgroups and chains of the Fischer simple group Fi22 and verify the Alperin weight conjecture and the Uno reductive conjecture for this group; the latter is a refinement of the Dade reductive and Isaacs-Navarro conjectures.

Resumen En este artículo se presenta una revisión de varias de las heurísticas de verificación de requisitos basadas en métricas desarrolladas por el Grupo de Ingeniería del Software de la Universidad de Sevilla. Esta revisión se basa en los datos empíricos obtenidos de prácticas de alumnos de segundo ciclo de la Ingeniería Informática de la Universidad de Sevilla. El análisis de los datos empí...

This editorial continues with our Young Investigator Perspectives series. Drs. Uno and Walton are young investigators who hold faculty positions. They completed a K12 postdoctoral program through the IRACDA (Individual Research and Career Development Award) program sponsored through the NIGMS institute at NIH. IRACDA programs exist at multiple institutions in the USA to combine postdoctoral tra...

En el mundo empresarial, la diferencia entre una empresa competitiva y otra no competitiva radica en la estrategia que presenta cada una de ellas para mantenerse en el mercado. Esta estrategia debe estar enfocada en explotar las fortalezas y manejar las debilidades de la organización, para posteriormente permitir la operatibilización de la estrategia mediante la correcta combinación de indicado...

A new class of Godunov-type numerical methods (called here weakly nonoscillatory or WNO) for solving nonlinear scalar conservation laws in one space dimension is introduced. This new class generalizes the classical nonoscillatory schemes. In particular, it contains modified versions of MinMod and UNO. Under certain conditions, convergence and error estimates for WNO methods are proved.

English. We present a study on the degree of homonymy between the lexicon of a morphological analyser for Latin and an Onomasticon. To understand the impact of homonymy, we discuss an experiment on four Latin texts of different era and genre. Italiano. L’articolo presenta uno studio sul grado di omonimia tra il lessico di un analizzatore morfologico per il latino e un Onomasticon. Al fine di co...
