  • Contributions to a Java recommender system

    Creator:
    Wang, Yun
    Abstract:
    Identifying the most relevant items in an e-commerce site is becoming more and more difficult nowadays because of the heavy overload of information. A Java Recommender System that uses Collaborative Filtering techniques has been developed to reduce such information overload and even personalize the information to the individual’s preference. The...

  • Silencer! : a tool for substrate noise coupling analysis

    Creator:
    Birrer, Patrick
    Abstract:
    This thesis presents Silencer!, a fully automated, schematic-driven tool for substrate noise coupling simulation and analysis. It has been integrated in the CADENCE DFII environment and seamlessly enables substrate coupling analysis in a standard mixed-signal design flow. Silencer! aids IC designers in the analysis of substrate noise coupling at different...

  • End-user testing for the Lyee methodology using the screen transition paradigm and WYSIWYT

    Creator:
    Brown, Darren, Burnett, Margaret, 1949-, and Rothermel, Gregg
    Abstract:
    End-user specification of Lyee programs is one goal envisioned by the Lyee methodology. But with any software development effort comes the possibility of faults. Thus, providing end users a means to enter their own specifications is not enough; they must also be provided with the means to find faults in...

  • Design of a variable gain, high linearity, low power baseband filter for WLAN transmitters

    Creator:
    Ranganathan, Sachin
    Abstract:
    A variable gain, high linearity, low power baseband filter for WLAN applications is implemented in a 1.5 V 3 V 0.15 μm CMOS process. This fourth-order low-pass filter, which is introduced in the transmit channel as a reconstruction filter between the D/A converter and the mixer, has a measured cut-off...

  • Generalizing WYSIWYT for use in the screen transition paradigm

    Creator:
    Brown, Darren
    Abstract:
    How can rigorous forms of testing be supported in a way that is both compatible with the visual aspect of visual programming languages, and usable by the audiences using those languages - even when the audience has no background in software engineering? Visual programs are likely to contain at least...

  • Random number generation on handheld devices for cryptographic applications

    Creator:
    Montville, Adam W.
    Abstract:
    Random number generation is important in many fields today. It is particularly important in the field of cryptography when generating nonce values, cryptographic keys, and other data required in many cryptographic applications. The proliferation of small, handheld devices that are typically connected to large networks via a wireless connection requires...

  • Three methods for estimating subpixel cover fractions in coarse resolution imagery

    Creator:
    Damon, Diane L.
    Abstract:
    Coarse resolution imagery, such as that produced by the MODIS instrument, poses the challenge of estimating sub-pixel proportions of di erent land cover types. This problem is di cult because of the variety and variability of vegetation within individual pixels. This thesis describes and compares two existing algorithms for estimating...

  • Algorithms and tools for optimization of integrated RF VCOs

    Creator:
    Kratyuk, Volodymyr
    Abstract:
    This thesis presents algorithms and tools for the automated design of RF LC CMOS voltage controlled oscillators (VCOs) with low phase noise given a set of specifications. The electromagnetic solver, ASITIC, combined with the circuit simulator, SpectreRF, allows optimization of the VCO circuit parameters and inductor layout. This approach gives...

  • The design of delta-sigma modulators for multi-standard RF receivers

    Creator:
    Liu, Mingliang
    Abstract:
    The transition from second-generation (2G) to third-generation (3G) wireless cellular and cordless telephone systems requires multi-standard adaptability in a single RF receiver equipment. An important answer to this request is the use of Delta-Sigma modulators for IF-to-baseband conversion, which will satisfy the dynamic range requirements for digital signal processing, and...

  • Test case prioritization

    Creator:
    Malishevsky, Alexey Grigorievich
    Abstract:
    Regression testing is an expensive software engineering activity intended to provide confidence that modifications to a software system have not introduced faults. Test case prioritization techniques help to reduce regression testing cost by ordering test cases in a way that better achieves testing objectives. In this thesis, we are interested...
