Imaging systems have an indisputable role in revealing vegetation posture under diverse flow conditions, image sequences being generated with off the shelf digital cameras. Such sensors are cheap but introduce a range of distortion effects, a trait only marginally tackled in hydraulic studies focusing on water-vegetation dependencies. This paper aims to bridge this gap by presenting a simple ca...

HyperMask is a system which projects an animated face onto a physical mask, worn by an actor. As the mask moves within a prescribed area, its position and orientation are detected by a camera, and the projected image changes with respect to the viewpoint of the audience. The lips of the projected face are automatically synthesized in real time with the voice of the actor, who also controls the ...

Virtual Touch Screen, on a projected area, is a system in which the projection on any ordinary flat surface provides us a graphical work-field for controlling specific kind of operations without any sophisticated touch sensors. Moreover, an ordinary screen area can be transformed into virtual touch screen with the use of a webcam and a projector. The webcam can take the picture of an indicator ...

The projected entangled pair state (PEPS) representation of quantum states on two-dimensional lattices induces an entanglement based hierarchy in state space. We show that the lowest levels of this hierarchy exhibit a very rich structure including states with critical and topological properties. We prove, in particular, that coherent versions of thermal states of any local 2D classical spin mod...

BACKGROUND Simplified projected aortic valve area (EOAproj) is a valuable echocardiographic parameter in the evaluation of low flow low gradient aortic stenosis (LFLG AS). Its widespread use in clinical practice is hampered by the laborious process of flow rate (Q) calculation. OBJETIVE This study proposes a less burdensome, alternative method of Q calculation to be incorporated in the origin...

This article assesses sugarcane yield gaps (YG) in Brazil to determine the degree to which production can be increased without land expansion. In our scenario assessments, we evaluated how much of the projected sugarcane demand to 2024 (for both sugar and bioethanol) can be satisfied through YG closure. The current national average yield is 62% of yield potential estimated for rainfed condition...

Knowledge of physical characteristics of Malaysian variety pomelo fruits are necessary for the design of some post harvesting, processing systems such as cleaning, handling, grading and packaging system. For proper development of pomelo grading systems, important relationships between the mass and some physical characteristics of pomelo fruits such as length, width, thickness, surface area, pro...

Improving health care systems, while containing cost pressures, is a key policy challenge in most OECD countries. The recent economic and financial crisis has weighed heavily on fiscal positions – with gross government debt projected to exceed 100% of GDP in the OECD area by 2011 – and reinforced the need to improve public spending efficiency. Public spending on health care is one of the larges...

In reality, it is a common phenomenon to perform nanoindentation test while the indenter is not perpendicular to the sample, which would cause the properties such as hardness and elastic modulus of sample to be somehow different from the true values. In this paper, the effects of indenter tilt on the results of nanoindentation were studied by finite element analysis (FEA) simulation. The result...

India is the second largest producer of potato in the world. The Indo-Gangeticplains (IGP) is the main potato growing region accounting for almost 85% of the1.8 Mha under the crop in India where it is grown as an irrigated crop during thewinter season. Since IGP is in sub-tropical plains, duration of the thermally suitablewindow is the main determinant limiting yields. Hence the impact of clima...
