Monetary Policy Uncertainty: Is There a Difference Between Bank of England and the Bundesbank/ECB?
No full textIt is widely believed that institutional arrangements influence the quality of monetary policy outcomes. Judged on its ‘transparency’ characteristics, therefore the Bank of England should do better than both the Bundesbank and ECB. However, studies based on market evidence show that on average, agents anticipate policy moves by both banks equally well. Since benefits from transparency should also show in a narrowing of the diversity in cross sectional forecasts, this paper extends the existing literature in an attempt to reconcile the contradictory evidence on ‘transparency’ of both banks. We show that the diversity in interest rate forecasts is greater under the Bundesbank/ECB than the Bank of England. Other factors than ‘transparency’ do not seem to affect interest rate uncertainty in Germany. Increasing difficulty in forecasting inflation appears to explain in part UK interest rate forecast dispersion.transparency, yield curve, forecasting uncertainty, Bank of England, Bundesbank, ECB
Design for novel enhanced weightless neural network and multi-classifier.
No full textWeightless neural systems have often struggles in terms of speed, performances, and memory issues. There is also lack of sufficient interfacing of weightless neural systems to others systems. Addressing these issues motivates and forms the aims and objectives of this thesis. In addressing these issues, algorithms are formulated, classifiers, and multi-classifiers are designed, and hardware design of classifier are also reported. Specifically, the purpose of this thesis is to report on the algorithms and designs of weightless neural systems.
A background material for the research is a weightless neural network known as Probabilistic Convergent Network (PCN). By introducing two new and different interfacing method, the word "Enhanced" is added to PCN thereby giving it the name Enhanced Probabilistic Convergent Network (EPCN). To solve the problem of speed and performances when large-class databases are employed in data analysis, multi-classifiers are designed whose composition vary depending on problem complexity. It also leads to the introduction of a novel gating function with application of EPCN as an intelligent combiner. For databases which are not very large, single classifiers suffices. Speed and ease of application in adverse condition were considered as improvement which has led to the design of EPCN in hardware. A novel hashing function is implemented and tested on hardware-based EPCN.
Results obtained have indicated the utility of employing weightless neural systems. The results obtained also indicate significant new possible areas of application of weightless neural systems
First Observations of G-Band Radar Doppler Spectra
No full textThe first Doppler spectra ever acquired by an atmospheric radar at 200 GHz (G-band) are presented. The observations were taken during a light precipitation event in May (rain rates <2 mm hr−1) at Chilbolton Observatory, UK, with coincident Ka-band and W-band Doppler radar measurements. The collected rain spectra agree with Mie theory predictions: at G-band they show significant reductions in the spectral power return—as compared to theoretical Rayleigh scattering—corresponding to high Doppler velocities (i.e., large raindrops) with the presence of multiple peaks and “Mie notches” in correspondence to the maxima and minima of the raindrop backscattering cross sections. The first two G-band Mie troughs correspond to smaller velocities/sizes than the first W-band Mie notch. These features offered by G-band radars pave the way toward applying, in rain, Mie notch vertical wind retrievals and multifrequency drop size distribution microphysical retrievals to smaller rain rates and smaller characteristic sizes than ever before
Tracer turbulence: the Batchelor--Howells--Townsend spectrum revisited
No full textGiven a velocity field u(x, t), we consider the evolution of a passive tracer θ governed by ∂tθ + u · ∇θ = Δθ + g with time-independent source g(x). When u is small in some sense, Batchelor, Howells and Townsend (J Fluid Mech 5:134, 1959) predicted that the tracer spectrum scales as |θk| 2 ∝ |k| −4|uk| 2. In this paper we prove that, for random synthetic two-dimensional incompressible velocity fields u(x, t) with given energy spectra, this scaling does indeed hold probabilistically, asymptotically almost surely for large |k| and small u. We also propose an asymptotic correction factor to the BHT scaling arising from the time-dependence of u
