Damping Behavior of the Phenolic Based Composite Friction Materials Containing Thermoplastic Elastomers (TPEs)
Attempts have been made for the first time to produce a friction material with thermal sensitive modulus by the inclusion of combined plastic/rubber properties of thermoplastic elastomers (TPE) as viscoelastic polymeric materials into the formulation for the purpose of increasing the damping behavior. In order to evaluate the viscoelastic parameters such as loss factor (tan δ) and elastic m...
متن کاملVentricular Assist Devices for Pediatric Heart Disease
Mechanical Circulation Assist Devices are designed for the treatment of acute and chronic heart failure and can be applied for different indications and assist period. Treatments that are carried out with Ventricular Assist Device System (VADs) have improved over course of time, within the practical applications of pediatric cardiac surgery. Pulsatile devices being in the lead, paracorporeal as...
متن کاملControl of Heart Assist Devices
In this paper, we discuss several control techniques for Ventricular Assist Devices (VADs) and describe a hierarchical control structure that can be used to regulate the operation of a turbo-hydrodynamic VAD. Early assist devices were pulsatile, and control usually focused on regulating flow, atrial and/or arterial pressures. In recent years, non-pulsatile turbo-hydronamic devices have been int...
متن کاملVentricular assist devices for heart failure
BACKGROUND Heart failure is a clinical syndrome of major epidemiological and economical importance. In Germany as in other industrialised countries it is one of the leading causes of mortality, morbidity and disability. For patients not responding to medical therapies ventricular assist devices are used as bridge to transplant, bridge to recovery or as destination therapy alternative to transpl...
متن کاملThermoplastic Elastomers with Photo-actuating Properties
This contribution reviews elastomeric materials with photo-actuation behavior with emphasis on thermoplastic elastomers and their composites. The principles of the photo-actuation and the main factors affecting the photo-actuation phenomena of thermoplastic elastomer materials are discussed in detail. The well-performing photoactuating systems involving both statistical and block copolymers-bas...
