Changes in EEG Spectra of a Child with Severe Disabilities in Response to Power Mobility Training

Self-initiated mobility in infancy and early childhood enhances the development of various cognitive processes such as spatial awareness, social interaction, language, and differential attentiveness.In a preliminary study, EEG was investigated as an objective measure for changes in brain activity due to power mobility training in children with multiple developmental disorders. The current study investigates changing power spectral characteristics in different frequency bands of EEG data recorded in a single child with multiple developmental disorders over multiple weeks of power mobility training.

Upper Extremity Kinematics in Sonographers during Kidney Scanning

Due to the prevalence of work-related musculoskeletal disorders in sonographers, this study evaluated upper extremity kinematics during kidney scans. The purpose of this study was to provide a greater understanding of joint range of motion, which could be helpful in assessing risk of injury. There were three scanning factors in this study: sonographer's position, ultrasound transducer design, and scanned kidney.

Stochastic Resonance-based Wavelet Transform on CT Images

The aim of the project was to examine whether Stochastic Resonance-based wavelet transform (SRWT) can be used to enhance iteratively reconstructed Computed Tomography images. Stochastic Resonance is achieved by combining white Gaussian noise with a weak periodic forcing signal. In resonance, they can bring a signal to cross a threshold and transit into another state. This phenomenon can be used to enhance low-contrast regions in medical images.
