Linearity Error in Clamp-On Ultrasonic Flowmeters Due to the Installation on Pipes Made of Dispersive Materials

2017 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2017
This article analyses and explains the implications that dispersive materials have over the linearity in flow measurement when a Clamp-on ultrasonic flowmeter is used. This is of capital importance because dispersive materials are commonly used in the manufacture of transducer wedges and pipes.

Validation of Intravoxel Incoherent Motion MRI Using Perfused Explanted Human Livers. [PDF]

Magn Reson Med
ABSTRACT Purpose Evaluate the feasibility of using perfused explanted human livers for validating intravoxel incoherent motion (IVIM). Methods Eight (n = 8) explanted livers from deceased donors were obtained. The portal vein and hepatic artery of each explanted liver were connected to a perfusion system.

Prevention of thrombus formation in blood pump by mechanical circular orbital excitation of impeller in magnetically levitated centrifugal pump. [PDF]

Artif Organs, 2023
Circular orbital excitation can prevent thrombus formation in blood pump. The proposed method was more effective than simple reciprocating vibration (previous study). The combination of proposed method and conventional anticoagulant therapy would show better effect.

On the Use of Ultrasonic Flowmeters for Cooling Energy Metering and Sub-Metering in Direct Expansion Systems

Energies, 2023
The Energy Efficiency Directive (EED, Directive 2012/27/EU) has made mandatory the installation of individual metering systems in the case of buildings with centralized heating/cooling and hot water sources (multi-apartment and multi-purpose buildings ...

The Thigh Saphenous Vein Versus the Calf Saphenous Vein: Searching for the Optimal Conduit for Coronary Artery Bypass Grafting. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Background The quality of saphenous vein (SV) grafts can vary depending on the site from which they are harvested. However, few studies have compared SV grafts harvested from the thigh with those harvested from the calf to explore which is more appropriate for use in coronary artery bypass grafting (CABG). In this study, we evaluated the graft
