This paper reports on an experimental investigation to determine the structure and mean flow quantities of round zero-net-mass-flux (ZNMF) jets. These jets are generated by a piston oscillating in cavity behind circular orifice. Several different patterns were observed with dye visualization parameter map these was generated. Cross-correlation digital particle image velocimetry used measure instantaneous two-dimensional in-plane velocity fields plane containing orifice axis. investigate...
Stent induced hemodynamic changes in the coronary arteries are associated with higher risk of adverse clinical outcome. The purpose this study was to evaluate impact stent design on wall shear stress (WSS), time average WSS, and WSS gradient (WSSG), idealized geometries using computational fluid dynamics. Strut spacing, thickness, luminal protrusion, malapposition were systematically investigated a comparison made between two commercially available stents (Omega Biomatrix). Narrower strut...
The Gaussian modulated continuous variable quantum key distribution (GM-CVQKD) protocol is known to maximise the mutual information between two parties during (QKD). An alternative modulation scheme discrete CVQKD (DM-CVQKD) protocol. In this paper, we perform a feasibility study for practical satellite-to-ground with focus on comparing existing GM-CVQKD and DM-CVQKD protocols application of performance recent reconciliation methods. We use link model which takes into account geometric...
ABSTRACT As wind turbines become larger and hence more flexible, the design of advanced controllers to mitigate fatigue damage optimise power capture is becoming increasingly important. The majority existing literature focuses on feedback that use measurements from turbine itself possibly an estimate or measurement current local profile. This work investigates a predictive controller can short‐term predictions about approaching field improve performance by compensating for actuation delays....
Abstract This paper investigates a new method for transient simulation of flow through wind turbine using an actuator technique. The aim, in the context wake simulation, is to develop alternative widely used disc model with increased resolution and range applications, same or less computational expense. In this model, sector method, forces applied fluid are distributed azimuthally maintain continuous solution time‐step intervals compared line method. Actuator results presented comparison...
Retarding field energy analyzers and Langmuir probes are routinely used to obtain ion electron distribution functions (IEDF, EEDF). These typically require knowledge of the first second derivatives I-V characteristics, both which can be obtained in various ways. This poses challenges inherent differentiating noisy signals, a frequent problem with electric-probe plasma diagnostics. A brief review commonly analog numerical filtering differentiation techniques is presented, together their...
Continuous variable quantum key distribution (CVQKD) is a developing method to secure information exchange in future networks. With the recent developments technology and greater access space, global network secured by CVQKD could be within reach. In this work, structures of existing QKD networks are analysed, how they can fit into general overarching three-layer architecture for endeavour network. Such comprise different links fibre free-space. The finite size limit secret rates (SKRs) with...
<title>Abstract</title> Rocket emissions damage the stratospheric ozone layer, which protects life from harmful solar radiation. To understand if significant losses could occur as launch industry grows, we examine two scenarios of aspirations. Our ‘ambitious’ scenario (2,040 launches/year) leads to a -0.29% depletion in annual-mean, near-global total column ozone, relative simulation with no rocket launches. Antarctic springtime decreases by 3.9%. ‘conservative’ (884 -0.17% annual depletion;...

ABSTRACT Accurate modelling of transient wind turbine wakes is an important component in the siting turbines within farms because wake structures that affect downwind performance and loading. Many current industry tools for these effects are limited to empirically derived predictions. A technique described coupling with aero‐elastic simulation dynamically model both operation structures. The feature this approach a flow simulation, which actively responds events through inclusion controller...
