Estudio experimental de la efectividad de la entrevista abierta frente a la entrevista independiente de contexto

Resumen. OBJETIVO: Estudiar la efectividad relativa de las técnicas de entrevista abierta y entrevista independiente de contexto en la identificación de requisitos para sistemas software. MÉTODO: Experimento controlado ensayando dos factores: “tipo de entrevista” (abierta e independiente de contexto) y “tipo de problema” (identificación de requisitos para dos sistemas software distintos). Debid...

Validity of Heavy Traffic Steady-state Approximations in Generalized Jackson Networks by David Gamarnik

We consider a single class open queueing network, also known as a generalized Jackson network (GJN). A classical result in heavy-traffic theory asserts that the sequence of normalized queue length processes of the GJN converge weakly to a reflected Brownian motion (RBM) in the orthant, as the traffic intensity approaches unity. However, barring simple instances, it is still not known whether th...

R4 Current Biology 27, R1–R18, January 9, 2017 At the time of going to press, the nominations have not included the post of a science advisor, so scientists in the US and their world-leading institutions and associations are wondering how, if at all, verifi able facts from the real world can reach the president. Writing in Science magazine, the CEO of the American Association for the Advancemen...

Red Blood Cell (RBC) transfusion is a common medical procedure, which most often involves stored RBC units. During storage, RBC quality degrades due to various factors (“storage lesion”). This decreases cell viability in-vivo and thus often compromises transfusion efficacy. The degradation of any given unit of RBC solution varies according to several factors besides time (e.g., variability amon...
