Townsend's (1976) attached eddy hypothesis states that the turbulent structure in the constant stress layer can be decomposed into attached and detached eddy motion. This paper proposes and tests methodology for separating the attached and detached eddy motion from time series measurements of velocity and temperature. The proposed methodology is based on the time-frequency localization and lter...

Synchronization of the contrast bolus peak and CT imaging aperture is a crucial issue for computed tomography angiography (CTA). It affects the CTA image quality and the amount of contrast dose. A whole-body CTA procedure means to scan from the abdominal aorta to pedal arteries. In this context, the synchronization is much more difficult with the asymmetric arterial flow in lower extremities th...

Purpose This study aims to examine the relationship between integrated reporting (IR) quality and corporate tax avoidance (CTA). IR is an emerging mechanism, while CTA practices are considered a hindrance inclusive sustainable growth. The also assesses moderating role of firm complexity on IR-CTA relationship. Additionally, this envisages that not static. Hence, it analyses across different int...

Forward Osmosis (FO) polyamide thin-film composite membranes have been prepared by interfacial polymerization using commercial UF polyethersulfoneas membrane support. Different interfacial polymerization times (10s, 30s and 60s) in the organic solution containing trimesoyl chloride (TMC) at constant mphenylenediamine (MPD) concentration (2% w/v) were studied. The synthesized polyamide membranes...

Synchronization of the contrast bolus peak and CT imaging aperture is a crucial issue for CTA. It effects the CTA imaging quality and the necessary amount of contrast dose. In this paper, we propose an optimal adaptive bolus chasing controller. The controller estimates and predicts the unknown two dimensional bolus density on line and then determines the optimal control actions. Tracking errors...

It is a relevant objective in thermal physics and building reciprocating internal combustion engines (RICE) to obtain new information about the thermal-mechanical characteristics of both stationary pulsating gas-flows complex gas-dynamic system. The article discusses physical features gas dynamics heat transfer flows along length system typical for RICE exhaust systems. Both an experimental set...
