  • Quantum dots-fullerene based molecular beacons for highly sensitive DNA detection

    Creator:
    Liu, Ye
    Abstract:
    We demonstrated a low-cost and high-sensitivity DNA detection method using quantum dot-fullerene based molecular beacons (MBs) and magnetic nanoparticles. The MB tethered magnetic nanoparticles can be well dispersed in analytes for efficient DNA capture and concentrated by an external magnetic field for enhanced fluorescence signal detection. The detection requires only...

  • High-speed switched-capacitor filters based on unity-gain buffers

    Creator:
    Bruneau, David
    Abstract:
    In this work a new voltage buffer, the drain-follower, achieves 300MHz band-width with 2pF load, a dc gain of 0.993V/V, 1mV offset voltage, -60 dB total harmonic distortion at 1.4Vpp output voltage and 6.5mW power dissipation from 5V supply. A unity-gain buffer switched-capacitor biquad filter has been implemented in 0.5μm...

  • EM-MAC : an energy-aware multi-channel medium access control protocol for multi-hop wireless networks

    Creator:
    Sivanantha, Akhil
    Abstract:
    The stupendous growth in wireless and mobile devices in the recent years has prompted researchers to look at innovative approaches that enable effective use of the available resources. In this thesis, we propose a medium access control (MAC) protocol, referred to as EM-MAC, that enables wireless devices with multi-channel access...

  • Time domain simulation of multiconductor lossy transmission lines by the method of characteristics

    Creator:
    Orhanovic, Neven
    Abstract:
    A numerical technique to compute the time domain response of multiconductor lossy uniform and nonuniform lines terminated in general nonlinear elements is presented. The technique is based on the generalized method of characteristics. The method transforms the original system of transmission line equations into a system of ordinary differential equations....

  • Modified conjugate gradient method for ADSL echo cancellation

    Creator:
    Inoue, Takao
    Abstract:
    In recent years, high speed data communications over twisted pair cables has gained tremendous demand. Asymmetric Digital Subscriber Line (ADSL) was standardized for use over twisted pair cables. A critical component in ADSL system is the echo canceller which is intended to discriminate unwanted echo signals caused by twisted pair...

  • Performance and optimization of pulsed UWB localization with large number of sources

    Creator:
    Kwon, Changho
    Abstract:
    Pulsed ultra-wideband (UWB) radio uses extremely short pulses to transmit information. Such pulses provide very fine timing information, which has led to technological advances in high-precision localization. This thesis focuses on techniques and experiments of Time-Difference-of-Arrival (TDOA) localization of a large number of simultaneous sources. First, common localization techniques such...

  • Design and Implementation of an Automated Star Tracking System

    Creator:
    Stark, Colin
    Abstract:
    An Automated Star Tracking System was designed and built for an undergraduate senior design project. The system was designed as a portable and easy to use means of tracking celestial objects, and is usable for a variety of both personal and professional purposes. The project was built around exploring the...

  • Tone burst deconvolution

    Creator:
    Rathja, Roy C.
    Abstract:
    The suitability of discrete least-squares optimal (Wiener) filters for deconvolution of tone-burst waveforms is studied. It is shown that: (1) such waveforms are not well suited to these filters without preprocessing, (2) the use of exponential weighting results in a significant improvement in filter performance and (3) that "phase-unwrapping" in...

  • Location Privacy Preservation for Optimal Sensing in Cognitive Radio Networks

    Creator:
    Grissa, Mohamed
    Abstract:
    Cognitive Radio Networks (CRNs) enable opportunistic access to the licensed channel resources by allowing unlicensed users to exploit vacant channel opportunities. One effective technique through which unlicensed users, often referred to as Secondary Users (SUs), acquire whether a channel is vacant is cooperative spectrum sensing. Despite its effectiveness in enabling...
