Analysis and Applications of Multiple State

Electrostatically Formed Nanowire Transistors

Electrostatically formed nanowire (EFN)-based transistors have recently been suggested as a single device with multiplexer functionality. In these transistors multiple gates and multiple drains transistors, the conduction path between source to one of the drains is determined by the bias applied to the two junction-side gates. If a specific bias is applied to the side gates, the conduction band electrons between them are confined to a well-defined area forming a narrow channel—the EFN. By applying a nonsymmetric bias on the side gates, the lateral position of the EFN can be controlled.

We present a simulation analysis of the different states of the MSET device, applications, the transient time between them and the power exerted during each transition. The dependence of transition time between states and leakage currents in cutoff state on different geometry parameters is also presented.

A discussion on the usage of the MSET device in digital applications will be presented along with an analog application of an RF switch.

Learning to see by listening

Abstract
Children may learn about the world by pushing, banging, and manipulating things, watching and listening as materials make their distinctive sounds-- dirt makes a thud; ceramic makes a clink. These sounds reveal physical properties of the objects, as well as the force and motion of the physical interaction. We've explored a toy version of such learning-through-interaction by recording audio and video while we hit many things with a drumstick.
We developed an algorithm the predict sounds from silent videos of the drumstick interactions. The algorithm uses a recurrent neural network to predict sound features from videos and then produces a waveform from these features with an example-based synthesis procedure. We demonstrate that the sounds generated by our model are realistic enough to fool participants in a "real or fake" psychophysical experiment, and that the task of predicting sounds allows our system to learn to visually distinguish different materials.

Visual Perception through Hyper Graphs

Abstract
Computational vision, visual computing and biomedical image analysis have made tremendous progress of the past decade. This is mostly due the development of efficient learning and inference algorithms which allow better and richer modeling of visual perception tasks.
Hyper-Graph representations are among the most prominent tools to address such perception through the casting of perception as a graph optimization problem. In this talk, we briefly introduce the interest of such representations, discuss their strength and limitations, provide appropriate strategies for their inference learning and present their application to address a variety of problems of visual computing.
