Abstract This study was conducted to simulate the sediment yield and evaluate best management practices (BMPs) for control in Azuari watershed, Upper Blue Nile basin, Ethiopia using Soil Water Assessment Tool (SWAT) model. As inputs model, 30 years (1991–2020) of daily values meteorological data were used. For model simulation, stream flow collected periods from 1988 2012. The area delineated i...

There has been a renewed interest in upper arm contouring given the recent advances and subsequent patient interest in weight loss. Patients undergoing bariatric surgery are often left with a significant amount of redundant skin and laxity of their upper extremity. Some patients within this group have excess fat in their upper arms with relatively good skin tone, while others have a paucity of ...

In order to improve the overall contouring performance, it appears that it is no longer possible to neglect dynamic coupling phenomena that occur during contour tracking, especially for linear motor systems which often move at high speed. This paper studies the high performance contour tracking control of linear-motor-driven tables. The table dynamics is first transformed into a task coordinate...

This paper reports on the perception of changing body image and well-being for patients who had undergone plastic surgery following massive weight loss. The exploratory, qualitative study was undertaken with 20 patients from one teaching hospital in the south of England. Semi-structured interviews were carried out and a thematic analysis of the data undertaken. The results provide important ins...

To achieve the high precision required in future contouring machining applications. accurate servo-controllers for the feed drives are needed. For this purpose conventional P controllers. which are utilized on many CNC systems, are not adequate. and more advanced control algorithms must be implemented. This paper summarizes existing servo-controllers for contouring applications and presents an ...

Applying the controller area network (CAN) bus, this paper proposes the integration of three advanced motion control designs: (1) the zero phase error tracking control (ZPETC) mainly for each individual axis in the multi-axis system, (2) the zero magnitude error tracking control (ZMETC) for each individual axis at the high speed in the multi-axis system and (3) the cross-coupled control (CCC) f...

We present a robust approach to creating 2.5D building models from aerial LiDAR point clouds. The method is guaranteed to produce crack-free models composed of complex roofs and vertical walls connecting them. By extending classic dual contouring into a 2.5D method, we achieve a simultaneous optimization over the three dimensional surfaces and the two dimensional boundaries of roof layers. Thus...

Material and methods Before 2007 radiation treatment planning-CT was done without contrast enhancement, MRI and F-FDG-PET/ CT were used only occasionally. From 2007 contrast enhanced planning-CT in addition to multimodality imaging was used routinely for every HNC. Additionally, in unclear or equivocal imaging findings of lymph nodes a re-report was performed with a higher sensitivity at the ex...

This paper describes an algorithm to extract adaptive and quality 3D meshes directly from volumetric imaging data. The extracted tetrahedral and hexahedral meshes are extensively used in the Finite Element Method (FEM). A top-down octree subdivision coupled with the dual contouring method is used to rapidly extract adaptive 3D finite element meshes with correct topology from volumetric imaging ...
