The aim of this paper is to improve the results of [o] about the theta series associated to the even extremal unimodular quadratic form. We prove that, in degree 3, the associated theta series is still unique for extremal even unimodular lattices of rank 32 and 48. For the ranks 40, 56, 72 we analyz

## Abstract An Erratum has been published for this article in Hydrological Processes 17(4) 2003, 883. Fourierβtransformβbased spectral analysis and filtering techniques, although potentially very useful, have seen little practical application in hydrology. We provide an overview of the Fourier tra
The use of time domain and frequency domain techniques in the analysis of geomorphological time series is discussed and the techniques of spectral analysis are introduced. An Excel worksheet is used to analyse wave-current data from Slapton Sands in Devon and the advantages and limitations of the te
Multiple time series usually arise in measurements on physical systems in one of two ways. The first way is when a set of time series arise on an 'equal footing.' A distant explosion might be recorded at several contiguous recording sites. From such series can be determined, for example, characteris
