Supramolecular Nanostructures Based On Calixarenes
(Chemistry & Biochemistry, 2007-08-23)
This dissertation describes a systematic approach towards the design, synthesis, characterization, and application of calixarene-based supramolecular nanostructures. Chapter 1 briefly overviews the field of supramolecular ...
Performance Analysis Of DPSK Systems With MIMO Employing EGC Over Wireless Fading Channels
(Electrical Engineering, 2007-09-17)
The proliferation of digital wireless communication services has increased the congestion of the available radio spectrum. In addition to that, wireless communications are encountered by multipath channel fading. To alleviate ...
A CMOS Ultra-wideband Differential Low Noise Amplifier
(Electrical Engineering, 2007-08-23)
In this thesis, a CMOS Ultra-wideband (UWB) Low noise Amplifier (LNA) was designed and simulated. In the design, specific architecture decisions were made in consideration of ultimately including this LNA in a system-on-chip ...
Characterization And Feasibility Study Of A Near Infrared CCD Imager For Monitoring Tumor Hemodynamics
(Biomedical Engineering, 2007-08-23)
Prostate cancer is one of the most common types of cancers diagnosed among North American men. Chemotherapy is generally used to target advanced metastatic prostate cancer. Near infrared spectroscopy (NIRS) has been ...
Building Energy-efficient Broadcast Trees Using A Genetic Algorithm In Wireless Sensor Networks
(Computer Science & Engineering, 2007-10-08)
In wireless broadcast environment, data can be transmitted to several nodes by a single transmission. The nodes in that environment have limited energy resources; therefore we need to reduce the energy consumption when ...
Investigation Of Brain Activities Using Two State-of-the-art Diffuse Optical Imagers
(Biomedical Engineering, 2007-09-17)
Near-Infrared Spectroscopy (NIRS) and diffuse optical imaging (DOI) are increasingly used to detect hemodynamic changes in the cerebral cortex induced by brain activity. The new commercially available DOI systems CW5 and ...
