Low-Cost Throttle-By-Wire-System Architecture For Two-Wheeler Vehicles [PDF]

Published March 04, 2024 by SAE International in United States, 2023
This paper investigates the performance of a lowcost Throttle-by-Wire-System (TbWS) for two-wheeler applications. Mopeds/scooters are still restricted environmentally harmful. Throttle-by-Wire-Systems can contribute to environmental protection by replacing conventional restrictors.

Tricuspid valve replacement outcomes in a diverse variety of valve replacement cases: Mortality, mechanical versus biological – A single-center study

Heart India, 2023
Background: The initial trial in tricuspid surgery is repair; however, replacement is done whenever the valve is badly diseased. Tricuspid valve replacement (TVR) as an isolated procedure and combined with other valve replacements presents a challenge as

Precession of entangled spin and pseudospin in double quantum dots [PDF]

Phys. Rev. B 105, 205418 (2022), 2022
Quantum dot spin valves are characterized by exchange fields which induce spin precession and generate current spin resonances even in absence of spin splitting. Analogous effects have been studied in double quantum dots, in which the orbital degree of freedom, the pseudospin, replaces the spin in the valve configuration. We generalize, now, this setup

First colombian tricuspid endovascular valve in valve using kissing balloon technique for failed bioprosthesis annular cracking

Revista Colombiana de Cardiología, 2022
We present the first case in Colombia of tricuspid endovascular valve in valve for failed bioprosthesis in a 40 years old patient with very high operative risk with great results, proposing kissing balloon annulus cracking technique as a practical ...

Transcatheter Double Valve Replacement to Treat Aortic Stenosis and Severe Tricuspid Regurgitation with 3D Printing Guidance after Mechanical Mitral Valve Replacement

Journal of Cardiovascular Development and Disease, 2022
Background: Transcatheter treatments of tricuspid regurgitation (TR) have been emerging as alternatives for high-risk patients. In contrast to the immobilization of the common transcatheter tricuspid device, using a radial force-independent stent valve ...

Evaluation of Ventricular Remodeling and Prognosis in Patients with Aortic Stenosis Who Underwent Surgical or Percutaneous Transcatheter Aortic Valve Replacement [PDF]

Brazilian Journal of Cardiovascular Surgery, 2022
Introduction: Aortic stenosis is the most common heart valve disease in the world, and patients that present with symptoms have a high mortality rate. Aortic valve replacement has the objective of promote left ventricular remodeling, reduce symptoms, and

A review of diaphragmless shock tubes for interdisciplinary applications [PDF]

, 2021
Shock tubes have emerged as an effective tool for applications in various fields of research and technology. The conventional mode of shock tube operation employs a frangible diaphragm to generate shockwaves. The last half-century has witnessed significant efforts to replace this diaphragm-bursting method with fast-acting valves.

57. Aortic valve replacement with sutureless valve and mitral valve repair in patient with infected aortic homograft

Journal of the Saudi Heart Association, 2016
The approach of implanting aortic sutureless valve inside the calcific homograft is suitable in redo surgery especially if associated with mitral valve surgery. Aortic valve replacement in patients who have undergone previous aortic root replacement with
