We propose a testing procedure for assessing the presence of threshold effects in nonstationary vector autoregressive models with or without cointegration. Our approach involves first testing whether the long-run impact matrix characterizing the VECM type representation of the VAR switches according to the magnitude of some threshold variable and is valid regardless of whether the system is pur...

globalization is a worldwide phenomenon. the concept globalization is a very recent term only establishing its current meaning in the 1970s, which emerged from the intersection of four inter related sets of communities of practice, academics, journalists, publishers. this paper models the channels through which globalization affects financial sector development in nigeria. to this end this stud...

Fault tolerant quantum error correction (QEC) networks are studied by a combination of numerical and approximate analytical treatments. The probability of failure of the recovery operation is calculated for a variety of CSS codes, including large block codes and concatenated codes. Recent insights into the syndrome extraction process, which render the whole process more efficient and more noise...

We prove a general form of bit flip formula for the quantum Fourier transform on finite abelian groups and use it to encode some general CSS codes on these groups.

We present a hybrid scheme for quantum computation that combines the modular structure of elementary building blocks used in the circuit model with the advantages of a measurement-based approach to quantum computation. We show how to construct optimal resource states of minimal size to implement elementary building blocks for encoded quantum computation in a measurement-based way, including sta...

Two versions of a fractionally cointegrating vector error correction model (FVECM) are presented. In the case of regular cointegration, linear combinations of fractionally integrated variables are integrated to lower order. Generalized cointegration is de…ned as the case where the cointegrating variables may be fractional di¤erences of the observed series. The concepts are applied to a model of...

RAGHAVACHAR, KAVITHA. Performance Modeling using a Genetic Programming based Model Error Correction Procedure. (Under the direction of Dr. G Mahinthakumar.) Application performance models provide insight to designers of high performance computing (HPC) systems on the role of subsystems such as the processor or the network in determining application performance and allow HPC centers to more accu...
