Abstract:

<p>From night vision goggles, to infrared imagers, to remote controlled bomb disposal robots; we are increasingly employing electronic vision sensors to extend or enhance the limitations of our own visual sensory system. And while we can make these systems better in terms of the amount of power they use, how much information they capture, or how much information they can send to the viewer, it is also important to keep in mind the capabilities of the human who must receive this visual information from the sensor and display system. The best interface between our own visual sensory system and t

Abstract:

The communication modes are a mathematical technique for the description of structural information in optical fields. These modes are orthogonal, optimally connected functions characteristic of the optical system. Mathematically they are obtained by the singular value decomposition (SVD) of the operator that represents the field propagation. In this dissertation, the foundations of the technique are described, and the theory is extended and applied to a variety of specific systems. In the Fresnel regime, the communication modes are closely related to the prolate spheroidal wavefunctions (PS

Abstract:

For a long time, information hiding has focused on carriers like images and audio files. A problem with these carriers is that they do not support hiding in new types of network-based services. Nowadays, these services often arise as a consequence of the increasingly demand for higher connection speed to the Internet. By introducing streaming media as a carrier of hidden information, hiding in new network-based services is supported. The main purposes with this thesis are to investigate how information can be hidden in streaming media and how it measures up compared to images and audio files.

Obesity bias has become the most acceptable form of prejudice in American society (Latner, O'Brien, Durso, Brinkman, & MacDonald, 2008).

Few studies have been done to show effective ways to reduce obesity bias. This study looked to expand the research on effective ways to reduce obesity bias.

Informed traders trade options on underlying securities to lower transaction costs and increase financial leverage for price trend and variance strategies. Options markets play a significant role in price discovery by incorporating private information about future prices for an underlying security into option prices.

Localizing content in neural networks provides a bridge to understanding the way in which the brain stores and processes information. A relatively powerful and yet accessible architectural setting in which to approach the question of whether and how such networks house content is provided by feedforward neural networks. Within this context, we establish the existence of polytopes in the state space of the hidden layer of neural networks as vehicles of content. We analyze these geometrical structures from an information-theoretic point of view, invoking mutual information to help define the con
