Medical Diagnostic Ultrasound [PDF]
, 2007 As early as 250 BCE, captains of ancient Greek ships would drop lead weights overboard to provide an estimate of water depth. They would count until those “sounders” produced an audible thud and in that way measure the propagation time of the falling ...

SSRN Electronic Journal, 2002 Summary: Electricity was born at the dawn of the last century. Households were inundated with a flood of new consumer durables. What was the impact of this consumer durable goods revolution? It is argued here that the consumer goods revolution was conducive to liberating women from the home.

Guidelines for conducting and reporting case study research in software engineering
Empirical Software Engineering, 2009 Case study is a suitable research methodology for software engineering research since it studies contemporary phenomena in its natural context. However, the understanding of what constitutes a case study varies, and hence the quality of the resulting ...

Two-phase flow patterns in turbulent flow through a dose diffusion pipe [PDF]
, 2005 A numerical investigation is carried out for turbulent particle-laden flow through a dose diffusion pipe for a model reactor system. A Lagrangian Stochastic Monte-Carlo particle-tracking approach and the averaged Reynolds equations with a k-e turbulence ...

Structural performance of steel-concrete sandwich beams with carbon nanofiber reinforcement [PDF]
, 2019 Cementitious materials such as concrete are typically characterised as quasi-brittle with low tensile strength and low strain capacity, which hence affect the long-term durability of the structure.

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Engineering geo‐engineering [PDF]
Meteorological Applications, 2011 AbstractThis paper reviews the geo‐engineering approach to tackling climate change. The failure of the 15th United Nations Framework Convention on Climate Change Conference of the Parties (COP15) to obtain a legally binding emissions reduction agreement makes the deployment of geo‐engineering solutions an increasingly attractive proposition.

Geographic variation in walking activity in the red flour beetle Tribolium castaneum
Population Ecology, EarlyView.This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.
