Bedrock river erosion is driven by channel hydraulics, which are not well understood for complex morphologies. Many bedrock rivers exhibit a constriction-pool-widening (CPW) morphology associated with submerged plunging flows. These flows cause velocity profile inversions resulting in high velocities near the bed and low on water surface. The first observations documenting were from relatively ...

Abstract The use of ceramic waste in concrete/mortar production as aggregate replacement or cement has been under consideration the last decade to find an effective way tackle growing hazard disposal. In this study, authors reutilize polishing (CPW) a filler replace equal volume paste mortar while keeping mixture proportions unchanged, i.e., new replacement. This design strategy allows larger a...

This article presents the accurate modeling results of nonlinear behavior a wide range silicon-based substrates at RF. The TCAD-based model includes carrier inertia effects and captures transient nonequilibrium phenomena in semiconductor substrate regions response to large-amplitude RF signal. is applied coplanar waveguide (CPW) lines measured on 19 different samples that have key differences t...

We have observed that the size and shape of the conducting reflector of CPW-fed slot antennas using loading metallic strips and a widened tuning stub have significant impact on the antenna impedance matching and radiation pattern. By shaping the reflecting conductor, noticeable enhancements in both radiation pattern which provides uni-directional all frequency operating band and characteristic ...

تحظى مشكلة الفقر باهتمام دولي ، ولم تعد مقتصرة على نقص الدخل وانما تشمل النقص في الاحتياجات الاساسية لمعيشة الإنسان فضلاً عن الحصول الحاجات المعرفية لذا يسعى معظم الدول الى استثمار مواردها الطبيعية والبشرية للحد من ظاهرة وتحقيق التنمية المستدامة .

In this paper, angular displacement and angular velocity sensors based on coplanar waveguide (CPW) transmission lines and S-shaped split ring resonators (S-SRRs) are presented. The sensor consists of two parts, namely a CPW and an S-SRR, both lying on parallel planes. By this means, line-to-resonator magnetic coupling arises, the coupling level being dependent on the line-to-resonator relative ...
