Objectives: Off-pump coronary artery bypass grafting (OPCAB) surgery is controversial in part because of the surgeon’s experience, which correlates with how the surgeon is trained.

Hysteresis in Experimental I–V Curves of Electron Hop Funnels [PDF]
Electron hop funnels provide a method to integrate field emission arrays into microwave vacuum electron devices, to protect the arrays, and to provide a method to study the secondary electron characteristics of dielectrics.

Funnel Control With Saturation: Linear MIMO Systems [PDF]
Tracking-by the system output-of a reference signal (assumed bounded with essentially bounded derivative) is considered in the context of a class of nonlinear, single-input, single-output systems modelled by functional differential equations and subject to input saturation.

An asymptotic output feedback controller for the hydraulic systems with model uncertainty compensation and prescribed performance is proposed here, where state observers, funnel function and nonlinear adaptive controller are integrated via backstepping ...

Public HMDs: Modeling and Understanding User Behavior Around Public Head-Mounted Displays [PDF]
Head-Mounted Displays (HMDs) are becoming ubiquitous; we are starting to see them deployed in public for different purposes. Museums, car companies and travel agencies use HMDs to promote their products. As a result, situations arise where users use them

Prediction of segregation in funnel and mass flow discharge [PDF]
In this paper we present a model to predict the onset and evolution of segregation during the discharge of binary mixtures of granular materials. The model accounts for the multi-phase and multi-component nature of the granular mixtures, to simulate the ...

Funnel Control for Linear DAEs [PDF]
AbstractWe study funnel control for linear differential‐algebraic multi‐input multi‐output systems which are not necessarily regular. We show that the funnel controller (that is a static nonlinear output error feedback) achieves ‐ for a special class of right‐invertible systems with asymptotically stable zero dynamics ‐ tracking of a reference signal ...

A multi-mirorr solution for the deflection of dangerous NEOS [PDF]
This paper presents some recent results on the deflection of potentially dangerous Near Earth Objects. A particular deflection technique, employing a swarm of mirrors focusing the light of the Sun on the surface of the asteroid, is described.
