This work is concerned with the prime factor decomposition (PFD) of strong product graphs. A new quasi-linear time algorithm for the PFD with respect to the strong product for arbitrary, finite, connected, undirected graphs is derived. Moreover, since most graphs are prime although they can have a product-like structure, also known as approximate graph products, the practical application of the...

Software reliability is an important feature of a good software implementation. However some faults which cause software unreliability are not detected during the development stages, and these faults create unexpected problems for users whenever they arise. At present most of the current techniques detect faults while a software is running. These techniques interrupt the software process when a...

This thesis describes the circuit level design of a 900MHz EA ring oscillator based phase-locked loop using 0.35um technology. Multiple phase noise theories are considered giving insight into low phase-noise voltage controlled oscillator design. The circuit utilizes a fully symmetric differential voltage controlled oscillator with cascode current starved inverters to reduces current noise. A co...

The three standard products (the Cartesian, the direct and the strong product) of undirected graphs have been wellinvestigated, unique prime factor decomposition (PFD) are known and polynomial time algorithms have been established for determining the prime factors. For directed graphs, unique PFD results with respect to the standard products are known. However, there is still a lack of algorith...

The Unified Matrix Polynomial Approach (UMPA) was developed to understand the basic similarities among various commercially used experimental modal analysis (EMA) algorithms like LSCE, ERA, PTD, PFD etc. It provided a common framework to develop most of these algorithms that have been developed in isolation, thus making it easier to understand and compare them. This paper extends the concept of...

An advanced safety architecture is the 2 out of 4-system (2oo4). In order to trigger the safety function at least two of the four channels must work correctly. It is said: “A 2oo4-system is 2-failure safe”. In order to classify the quality of a system we calculate different parameters. In the report equations are indicated for PFD for normal and common-cause-failures. Also the Markov-model for ...

Frequency conversion based on three-wave mixing is a critical nonlinear optic application, extending the frequency range of existing lasers and realizing frequency-transduced detectors in wavelength that lacks an effective detector. Phase matching vital for conversion. The advantages quasi-phase (QPM) over birefringent phase are lack walk-off effect, maximum coefficient, entire transparency win...

We propose a way to measure the momentum p of a nanomechanical oscillator. The p detector is based on two tunnel junctions in an Aharonov-Bohm-type setup. One of the tunneling amplitudes depends on the motion of the oscillator, the other one not. Although the coupling between the detector and the oscillator is assumed to be linear in the position x of the oscillator, it turns out that the finit...
