Plasmatron fuel converters have been investigated for the conversion of a wide range of fuels. This is a paper of a series of papers describing an effort to investigate experimentally and computationally plasmatron methane reformers. This paper describes the fluid dynamics modeling of the plasmatron methane reformer, with the hope of understanding air/methane mixture and mixing rates in the reg...

recent findings in stem cell biology have opened a new window in regenerative medicine. the endometrium possesses mesenchymal stem cells (mscs) called endometrial stem cells (enscs) having specific regenerative properties linked to adult stem cells. they contribute in tissue remodeling and engineering and were shown to have immuno-modulating effects. many clinical trials were undertaken to asce...

homogenous charge compression ignition (hcci) combustion is spontaneous multi-site combustion of a nominally premixed air/fuel mixture that exhibits high rate of pressure rise and short combustion duration. to avoid excessive pressure rise rate and knocking, hcci engines are fueled with highly diluted mixture using a combination of excess air and/or egr. hcci combustion is attractive due to ext...

many old damaged and undamaged building structures do not meet the criteria of modern seismic design codes. such structures need to be seismically enhanced. the main objective of this paper is to propose and validate the effectiveness of an upgrade scheme for non-seismic buildings using steel plate shear walls (spsw). the upgrade is carried out considering a probability-based drift-based criter...

PURPOSE This study aimed to determine whether upgrade cardiac resynchronization therapy (CRT) shows better outcomes than de novo CRT. To do so, we compared the efficacy of CRT between de novo and upgrade groups, focusing particularly on the effect of upgrade CRT on patients with pacing-induced cardiomyopathy (PiCM). MATERIALS AND METHODS PiCM was defined as new-onset dilated cardiomyopathy fo...

A singularly perturbed model is proposed for a system comprised of a PEM Fuel Cell(PEM-FC) with Natural Gas Hydrogen Reformer (NG-HR). This eighteenth order system is decomposedinto slow and fast lower order subsystems using singular perturbation techniques that provides tools forseparation and order reduction. Then, three different types of controllers, namely an optimal full-order,a near-opti...

This paper presents an implementation of the widely used speech analysis tool Praat as a web application with an extended functionality for feature annotation. In particular, Praat on the Web addresses some of the central limitations of the original Praat tool and provides (i) enhanced visualization of annotations in a dedicated window for feature annotation at interval and point segments, (ii)...

This paper studies a condition-based predictive maintenance policy in the presence of imperfect repairs for deteriorating systems. The effect is assumed to be random sense that action reduces systems degradation level by proportion. associated distribution allows characterizing repair efficiency. As an example, beta considered. It defining wide range efficiencies. A with aperiodic and inspectio...
