String players know that bowing properly is the hardest skill they have to learn. In other work 4], we develop an algorithm that calculates bowings for BowTech, a project that supports string performers. This algorithm takes a signiicant amount of time to execute (in our second test case, over an hour for the implementation, written in Ada). We have implemented the algorithm in GpH, a parallel ...

This paper reexamines foreign currency markets for evidence of fractional integration, and extends the extant literature in several important dimensions. First, we utilize a new semiparametric wavelet-based estimator, which is far superior to the more prevalent GPH estimator on the basis of mean squared error. Second, we utilize a broader and longer sample, which better facilitates the detectio...

This article investigates the forward market efficiency by testing the unbiased forward exchange rate hypothesis using nine currencies vis-à-vis the U.S. dollar. The empirical tests are conducted using monthly data during the period between January 1985 and December 1996 and two different methods of cointegration tests, a fractional (GPH) test and the HarrisInder test. The two cointegration tes...

Like several other Escherichia coli bacteriophages, transposable phage Mu does not develop normally in groE hosts (M. Pato, M. Banerjee, L. Desmet, and A. Toussaint, J. Bacteriol. 169:5504-5509, 1987). We show here that lysates obtained upon induction of groE Mu lysogens contain free inactive tails and empty heads. GroEL and GroES are thus essential for the correct assembly of both Mu heads and...

In this paper we introduce the concept an implementation of distributed programming in PFL – a process functional programming language and describe implementation of concurrency in other Haskell–like parallel functional languages – Concurrent Haskell and GpH. The process of writing parallel program is complicated by the need to specify both the parallel behaviour of the program and the algorith...

algebra is one of the most powerful unifying paradigms of twentieth century mathematics. A vast field of research in its own right, it is also a key tool in other areas of mathematics, in physics, in chemistry and in computer science. In the last thirty years, computational tools have played an increasing role in the development and application of abstract algebra, until today, computational al...

The purpose of this note is to prove a lower bound for the estimation of the memory parameter of a stationary long memory process. The memory parameter is defined here as the index of regular variation of the spectral density at 0. The rates of convergence obtained in the literature assume second order regular variation of the spectral density at zero. In this note, we do not make this assumpti...

Abstract Coastal flooding is one of the most costly and deadly natural hazards facing US Mid-Atlantic region today. Impacts in this heavily populated economically significant are caused by a combination location’s exposure forcing from storms sea-level rise. Tropical cyclones (TCs) mid-latitude (ML) weather systems each have extreme coastal region. Skew surge was computed over tidal cycle for p...
