In the year 1994 the DLR in Cologne inaugurated a 20 kW solar furnace for technological and scientific experiments. One of the main applications of the solar furnace is the research on photochemical reactions using concentrated sunlight. For this purpose exact knowledge of the spectral...

Purpose – In this study, the author aims to examine the behavior of QQQ options at the time of the QQQ move from AMEX to NASDAQ on December 1, 2004. The author addresses the questions: is there a relation between hedging and speculation, if such a relation exists considering the improvement in...

Spectral analysis is applied to the empirical identification of terms of trade cycles, in the secular evolution, 1870-2009, of a group of extreme-landabundant countries: Argentina, Australia, Canada, New Zealand, and Uruguay. Estimates of the power density spectrum functions produce...

This paper explores frequency-specific implications of measurement error for the design of stabilization policy rules. Policy evaluation in the frequency domain is interesting because the characterization of policy effects frequency by frequency gives the policymaker additional information about...

This paper studies asset returns adopting an alternative strategy to assess a model s goodness of fit. Based on spectral analysis, this approach considers a model as an approximation to the process generating the observed data, and characterizes the dimensions for which the model provides a good...

A regional telemetric network of twelve digital broad-band seismic stations has been in full operation since the beginning of 1999, in Greece, operated by the Institute of Geodynamics of the National Observatory of Athens (GI-NOA). On 7 September1999, a M<Subscript>L</Subscript>=5.4 main shock occurred just 18...</subscript>

A few years ago the Canadian Hydrographic Service initiated a major upgrade toall tide gauges and tsunami stations on the coast of British Columbia (B.C.). Thisprogram was undertaken to address shortcomings of the earlier digital systems andwas driven by concerns about emergency response...

Since 1996 the Collaborative Research Center (CRC) 461``Strong Earthquakes: A Challenge for Geosciences andCivil Engineering'' is funded by the DeutscheForschungsgemeinschaft (German Research Foundation) asa German contribution to the UN initiative``International Decade of Disaster Reduction''...

This paper introduces a class of cointegration tests based on estimated low-pass and high-pass regression coefficients from the same wavelet transform of the original time series data.  The procedure can be applied to test the null of cointegration in a n + k multivariate system with n...
