A non-linear observer for unsteady three-dimensional flows [PDF]
, 2007 A method is proposed to estimate the velocity field of an unsteady flow using a limited number of flow measurements. The method is based on a non-linear low-dimensional model of the flow and on expanding the velocity field in terms of empirical basis ...

Low “gradient”, low flow aortic stenosis [PDF]
Heart, 2006 Aortic stenosis is thought to have a long, asymptomatic latent phase during which the risk of sudden death is low. In fact symptoms can be revealed by treadmill exercise in a large proportion of apparently asymptomatic patients.1 Patients may limit exercise to avoid symptoms or may fail to recognise the presence of exertional breathlessness or ascribe ...

Hydrogeological approach to the regional analysis of low flow in medium and small streams of the hilly and mountainous areas of Serbia [PDF]
Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2006 During the long rainless spells of the dry season, flows in medium and small streams get reduced to what is generally known as "low flow". For ungauged streams, the controlling "low flows" are determined using the regional analysis method.

LOW FLOW ON THE RIVERS OF THE EUROPEAN PART OF RUSSIA AND ITS HAZARDS
Geography, Environment, Sustainability, 2016 This paper reviews the changes in river flow of the European part of Russia during the low-flow period, characterizing groundwater flow feeding. River flow oscillations were analyzed for winter and summer periods. Statistical analyses of average low flow

Tunable sensor response by voltage-control in biomimetic hair flow sensors [PDF]
, 2013 We present an overview of improvements in detection limit and responsivity of our biomimetic hair flow sensors by electrostatic spring-softening (ESS). Applying a DC-bias voltage to our capacitive flow sensors improves the responsively by up to 80% for ...

Low flow frequency analysis by L-moments method (Case study: Iranian Central Plateau River Basin) [PDF]
Desert, 2015 Knowledge about low flow statistics is essential for effective water resource planning and management in ungauged orpoorly gauged catchment areas, especially in arid and semi-arid regions such as Iran.
