Simulation and Animation in Optical Fiber Communication

ABSTRACT

Students find certain concepts in fiber optic communication theory difficult to grasp. A classic example is electromagnetic mode theory in cylindrical coordinates. The solutions of the differential equation which describe the modes of the fiber are Bessel Continue reading

Algorithms and Representations for Visual Recognition

ABSTRACT

We address various issues in learning and representation of visual object categories. A key component of many state of the art object detection and image recognition systems, is the image classifier. We first show that a large number of classifiers used in Continue reading

Multi-objective optimization for battery electric vehicle power train topologies

ABSTRACT

Electric vehicles are becoming more popular in the market. To be competitive, manufacturers need to produce vehicles with a low energy consumption, a good range and an acceptable driving performance. These are dependent on the Continue reading

Mining Requirements from Closed-Loop Control Models

ABSTRACT

Formal verification of a control system can be performed by checking if a model of its dynamical behavior conforms to temporal requirements. Unfortunately, adoption of formal verification in an industrial setting is a formidable challenge as design Continue reading

A pattern recognition method for electronic noses based on an olfactory neural network

ABSTRACT

Artificial neural networks (ANNs) are generally considered as the most promising pattern recognition method to process the signals from a chemical sensor array of electronic noses, which makes the system more bionics. This paper presents a chaotic Continue reading

Conversion of Artificial Recurrent Neural Networks to Spiking Neural Networks for Low-power Neuromorphic Hardware

ABSTRACT

In recent years the field of neuromorphic low-power systems gained significant momentum, spurring brain-inspired hardware systems which operate on principles that are fundamentally different from standard digital computers and thereby Continue reading

An affordable, open-source, microscale conductivity and temperature probe for density measurements in stratified flows

ABSTRACT

In stratified flows, conductivity (combined with temperature) is often used to measure density. The conductivity probes typically used can resolve very fine spatial scales, but can be fragile, expensive to replace, and sensitive to environmental noise. Continue reading

Modeling the Human Knee using Tensegrity

ABSTRACT

This thesis presents a preliminary investigation of using the principles of tensegrity to model the interactions that make up the human knee. The main theory behind tensegrity is to suspend compressionable members in a network for tensile members. Continue reading

Aperture Coupled Microstrip Antenna Design and Analysis

ABSTRACT

A linearly-polarized aperture coupled patch antenna design is characterized and optimized using HFSS antenna simulation software. This thesis focuses on the aperture coupled patch antenna due to the lack of fabrication and tuning documentation Continue reading
