En esta tesis presentamos dos modelos de fenómenos cuánticos donde estudiamos comportamientos resonantes. El primero corresponde a una partícula atrapada por una barrera defi nida por una Delta de Dirac en el semieje ...

Some individuals with reduced motor function rely on scanning keyboards to operate computers. A problem observed with scanning keyboards is that errors typically occur during the first group or first cell of a group. This ...

Ti-6Al-4V alloy turbine components for aeronautical applications operate at a steady state after reaching the maximum stress during each duty cycle. The load holds combined with the fatigue process causes a phenomenon ...

This paper aims to explain the factors that determine the dwell time of subway trains in Santiago, Chile. On the basis of morning rush-hour video recordings of Line 1’s most critically congested station, Baquedano, explanatory ...

The ability to use the movements of the eyes to write is extremely important for individuals with a severe motor disability. With eye typing, a virtual keyboard is shown on the screen and the user enters text by gazing at ...

This research proposes an equilibrium assignment model for congested public transport corridors in urban areas. In this model, journey times incorporate the effect of bus queuing on travel times and boarding and alighting ...

In this paper, we propose an extension of the invariance principle for nonlinear switched systems under dwell-time switched solutions. This extension allows the derivative of an auxiliary function V, also called a Lyapunov-like ...

The ability to type using eye gaze only is extremely important for individuals with a severe motor disability. To eye type, the user currently must sequentially gaze at letters in a virtual keyboard and dwell on each desired ...

The proposed works consists in the research on the electric power consumption in a Brazilian municipality and effective financial economy and demand the power grid with the installation of solar water heating. The field ...
