Abstract: Fulcrum network codes, which are a network coding framework, achieve three objectives: (i) to reduce the overhead per coded packet to almost 1 bit per source packet; (ii) to operate the network using only low field size operations at intermediate nodes, dramatically reducing complexity in the network; and (iii) to deliver an end-to-end performance that is close to that of a high field size network coding system for high-end receivers while simultaneously catering to low-end ones that can only decode in a lower field size. Sources may encode using a high field size expansion to increase the number of dimensions seen by the network using a linear mapping. Receivers can tradeoff computational effort with network delay, decoding in the high field size, the low field size, or a combination thereof.

Abstract: The invention relates to a method for providing quantitative measures of the flow property of a blood vessel. The method is based on analyzing cross-sectional images of a vessel by estimating the area of the lumen of the vessel. The method comprises steps of determining a point contained within the walls of the vessel, determining a closed path which approximates the inner circumference of the wall of the vessel, and determining the area of the closed path when the vessel is most expanding in order to get a measurement of the maximum lumen. This method may enable the clinical personnel to quickly evaluate the flow property e.g. of an inserted bypass vessel and, thereby, conclude if the surgical intervention is successful or if adjustments are required.

A noisy element(VF, HA), e.g. a ventilation fan (VF)or a turbulent noise source (HA),generates acoustic noise. A loudspeaker (L) with a diaphragm (D) is arranged such that a first side (S1) of the diaphragm (D) is in contact with the fluid (M) on a first side (P1) of the noisy element(VF), and a second side (S2) of the diaphragm (D) is in contact with the fluid (M) on a second side (P2) of the noisy element (VF).

Abstract: A system for monitoring a fetus in a pregnant woman, and/or the maternal health risk for pregnancies complicated by such as pre-eclampsia and hypertensive disorders is configured to be worn by the pregnant woman, preferably so as to allow monitoring during daily life, e.g. in the form of an adhesive patch. The unit has a sound sensor, e.g. a microphone or accelerometer, to be positioned on the skin of the abdominal area so as to detect a vascular sound from umbilical arteries of the fetus or from the uterine arteries of the pregnant woman. The sound sensor is functionally connected to a processing unit which executes a processing algorithm on the captured vascular sound and extracts a signal parameter accordingly. The processing unit then communicates the signal parameter, e.g. using an audio signal, a visual display or by means of a wired or a wireless data signal.

Abstract: The invention provides a method for estimating if a patient suffering from Chronic Obstructive Pulmonary Disease (COPD) is approaching an exacerbation. Data with connected data indicative of levels of blood oxygen saturation obtained from the patient and their respective time of measurements are received, and a processor executes an algorithm involving: 1) calculating a statistical measure, e.g. a regression, of the level of blood oxygen saturation data taking into account available data within a time window with a limited length back in time, e.g. 30 days back in time, and 2) estimating if the patient is approaching an exacerbation by comparing a value obtained from said statistical measure to a reference value. Finally, an output indicative of a result of said estimation is generated. The method can ensure that COPD patients, e.g. in tele homecare, are properly treated before suffering from a severe exacerbation that could necessitate hospitalization.
