Spectrum Analysis and Prediction Using Long Short Term Memory Neural Networks and Cognitive Radios

Description: One statement that we can make with absolute certainty in our current time is that wireless communication is now the standard and the de-facto type of communication. Cognitive radios are able to interpret the frequency spectrum and adapt. The aim of this work is to be able to predict whether a frequency channel is going to be busy or free in a specific time located in the future. To do this, the problem is modeled as a time series problem where each usage of a channel is treated as a sequence o… more

The Influence of Disease Mapping Methods on Spatial Patterns and Neighborhood Characteristics for Health Risk

Description: This thesis addresses three interrelated challenges of disease mapping and contributes a new approach for improving visualization of disease burdens to enhance disease surveillance systems. First, it determines an appropriate threshold choice (smoothing parameter) for the adaptive kernel density estimation (KDE) in disease mapping. The results show that the appropriate threshold value depends on the characteristics of data, and bandwidth selector algorithms can be used to guide such decisions a… more

Preservice Teachers' Beliefs about Writing and Their Plans to Teach Writing: The Apprenticeship of Observation

Description: Preservice teachers (PSTs) bring a plethora of knowledge and experiences to their educator preparation courses. The PSTs have also formed ideas about how to teach based on their observations during the thousands of hours they spent as students in the classroom from kindergarten through high school graduation. This phenomenon, coined by Lortie, is called the apprenticeship of observation. Past research has focused on the apprenticeship of observation in general while neglecting to specifically e… more

Evaluation of Call Mobility on Network Productivity in Long Term Evolution Advanced (LTE-A) Femtocells

Description: The demand for higher data rates for indoor and cell-edge users led to evolution of small cells. LTE femtocells, one of the small cell categories, are low-power low-cost mobile base stations, which are deployed within the coverage area of the traditional macro base station. The cross-tier and co-tier interferences occur only when the macrocell and femtocell share the same frequency channels. Open access (OSG), closed access (CSG), and hybrid access are the three existing access-control methods … more
