Positive Control With Maximum Stability Radius For Continuous-Time Dynamic Systems, Amirreza Oghbaee

Electrical and Computer Engineering Master's Theses

Positive systems have attracted much attention nowadays due to their numerous applications in modeling and control of physical, biological and economical systems. The state trajectory of such system remains in the nonnegative quadrant of the state space for any given nonnegative initial condition. This class of systems have nice stability and robustness properties. One can take advantage of these interesting properties to robustly stabilize general dynamic systems such that the closed-loop system becomes positive. One of the most important measures in robust control analysis is stability radius. This measure provides the amount of uncertainty that system can cope with before ...

Automatic Registration Of Fused Lidar/Digital Imagery (Texel Images) For Three-Dimensional Image Creation, Scott E. Budge, Neeraj S. Badamikar, Xuan Xie

ECE Faculty Publications

Several photogrammetry-based methods have been proposed that the derive three-dimensional (3-D) information from digital images from different perspectives, and lidar-based methods have been proposed that merge lidar point clouds and texture the merged point clouds with digital imagery. Image registration alone has difficulty with smooth regions with low contrast, whereas point cloud merging alone has difficulty with outliers and a lack of proper convergence in the merging process. This paper presents a method to create 3-D images that uses the unique properties of texel images (pixel-fused lidar and digital imagery) to improve the quality and robustness of fused 3-D images ...

Automated Detection Of Puffing And Smoking With Wrist Accelerometers, Qu Tang

Electrical and Computer Engineering Master's Theses

Real-time, automatic detection of smoking behavior could lead to novel measurement tools for smoking research and "just-in-time" interventions that may help people quit, reducing preventable deaths. This paper discusses the use of machine learning with wrist accelerometer data for automatic puffing and smoking detection. A two-layer smoking detection model is proposed that incorporates both low-level time domain features and high-level smoking topography such as inter-puff intervals and puff frequency to detect puffing then smoking. On a pilot dataset of 6 individuals observed for 11.8 total hours in real-life settings performing complex tasks while smoking, the model obtains a cross ...

Detecting Body Cavity Bombs With Nuclear Quadrupole Resonance, Michael Collins

Electrical and Computer Engineering Master's Theses

Nuclear Quadrupole Resonance (NQR) is a technology with great potential for detecting hidden explosives.

A Constrained Genetic Algorithm Based On Constraint Handling With Ks Function And Grouping Penalty, Innovative Research Publications Irp India, Jiang Zhansi, Jiang Yulong, Ma Liquan, Feng Jianguo

Innovative Research Publications IRP India

In order to overcome the limitation when using traditional genetic algorithm in solving constrained optimization problems, this paper presents a new method of constrain handling to solve the constrained optimization problems. Firstly, the method makes full use of the condensed characteristics of the KS function to transform multi-constrained optimization problem into a single constraint optimization problem. And then a group penalty method is adopted by genetic algorithm. Aggregate constraint reduces the solution scale effectively and improves the efficiency of searching for global optimization solution. The method of penalty in grouping is used to overcome the difficulty of penalty coefficient selection ...

Dehaze The Image Using Directed Filter Method After Blind Dehazing, Innovative Research Publications Irp India, Kanchan Gahlod, Hemant Verma

Innovative Research Publications IRP India

Haze is generally phenomenon that an atmospheric stuff that greatly degrades the visibility of outdoor scenes. This phenomenon occurs due to the atmosphere constituent parts that absorb and scatter the light. We use the spread map of image in terms of intensity of image except a continuous region which has no edge information. The scheme performs a per-pixel manipulation, which is direct to implement, and then apply the Directed filter to improve the image quality. The simulation results demonstrate the comparative results and even better than the more complex state-of-the-art techniques, having the advantage of being appropriate for real-time applications

Energy Conservation Day: Symbolism Doesn’T Pay, Hippu Salk Kristle Nathan

Hippu Salk Kristle Nathan

The much publicised panting competition at school level on the occasion of Energy Conservation Day was a good effort to send message to consumers to influence their energy consumption behaviour. But the effect is minuscule.

As a child one might have walked or cycled to school. But as a breadwinner, once energy related decisions largely get influenced by one's income level and opportunities and restrictions.

Power Management Strategies For Islanded Microgrids, Hisham Mahmood

University of Western Ontario - Electronic Thesis and Dissertation Repository

The focus of this thesis is on developing power management strategies for islanded microgrids, at the primary and the secondary hierarchal control layers. At the Primary Control Layer, the main objective of the proposed strategies is to achieve decentralized power management of Photovoltaic (PV) and battery storage in islanded microgrids. In contrast to the common approach of controlling the PV unit as a current source, in the proposed strategies, the PV unit is controlled as a voltage source that follows a multi-segment adaptive power/frequency characteristic curve. The strategies are implemented locally at the units using multi-loop controllers without relying ...
