Method of forming dynamic membrane on stainless steel support
A suitable member formed from sintered, powdered, stainless steel is contacted with a nitrate solution of a soluble alkali metal nitrate and a metal such as zirconium in a pH range and for a time sufficient to effect the formation of a membrane of zirconium oxide preferably including an organic polymeric material such as polyacrylic acid
Gross loan flows
Changes in net lending hide the much larger and more variable gross lending flows. We present a series of stylized facts about gross loan flows and how they vary over time, bank size, and the business cycle. We look at both the intensive (increases and decreases) and extensive (entry and exits) margins. We compare these results with the output from a simple stochastic search model.Bank loans ; Business cycles
Fast Differential Emission Measure Inversion of Solar Coronal Data
We present a fast method for reconstructing Differential Emission Measures
(DEMs) using solar coronal data. On average, the method computes over 1000 DEMs
per second for a sample active region observed by the Atmospheric Imaging
Assembly (AIA) on the Solar Dynamics Observatory (SDO), and achieves reduced
chi-squared of order unity with no negative emission in all but a few test
cases. The high performance of this method is especially relevant in the
context of AIA, which images of order one million solar pixels per second. This
paper describes the method, analyzes its fidelity, compares its performance and
results with other DEM methods, and applies it to an active region and loop
observed by AIA and by the Extreme-ultraviolet Imaging Spectrometer (EIS) on
Hinode.Comment: 22 Pages, 11 Figures; submitted to The Astrophysical Journal. This
version (2) includes clarifications in the text and reflects improvements to
the DEM cod
Pricing kernels, inflation, and the term structure of interest rates
We estimate a discrete-time multivariate pricing kernel for the term structure of interest rates, using both yields and inflation rates. This gives a separate estimate of the real kernel and the nominal kernel, taking into account a relatively sophisticated dynamical structure and mutual interaction between the real and nominal side of the economy. Along with obtaining an estimate of the real term structure, we use the estimates to obtain a new perspective on how real and nominal influences interact to produce the observed term structure.Inflation (Finance) ; Interest rates
Assisted Services - Physical support or psychological blow?
Work by Yoxall (2010) and Light (2010) showed that the relationship between artefacts and their use is complex; often beyond mere functional and physical use to a wider psychosocial context. Lack of understanding of this psychosocial aspect of product or service use immediately compromises the product or services design and future success. Further, in attempting to alleviate one issue through improved design we may create others. There is then an inherent complexity in the provision of design
solutions that could be specific for each design. That the design process is complex and is involved in attempting to provide answers to 'wicked' problems (Rittel and
Weber, 1973) is well understood. However, little work has been undertaken investigating the relationship between design solutions (either artefacts or services) and their effect on wellbeing. To that end the authors have undertaken a number of case studies outlining the complexity of design solutions, the unintended
consequences and the effects on wellbeing of the individuals studied. Further the authors attempt to develop enhanced design processes to understand the complexity of the design solutions proposed and improve their effectiveness.
The development of this understanding has required an interdisciplinary approach and has been a significant factor in arriving at the recognition of the importance of
these psychosocial attachments. Hence this work examines these case studies in detail and examines the benefits and issues of interdisciplinary research activity
