Hedging performance of multiscale hedge ratios [PDF]
Journal of Futures Markets, 2019 AbstractIn this study, the wavelet multiscale model is applied to selected assets to hedge time‐dependent exposure of an agent with a preference for a certain hedging horizon. Based on the in‐sample and out‐of‐sample portfolio variances, the wavelet‐based generalized autoregressive conditional heteroskedasticity (GARCH) model produces the lowest ...

ESTIMATION OF MOST PROBABLE PRODUCING ABILITY VALUE FOR CALF BIRTH'S PERFORMANCE IN SUMBA ONGOLE COWS [PDF]
Journal of the Indonesian Tropical Animal Agriculture, 2016 An estimation of most probable producing ability (MPPA) value based on the calves performance is very important for the cow selection. The birth data record of 48 Sumba Ongole (SO) cows and record data from 52 callf birth’s performance were used to ...

The Effect of Aspect Ratio on Compressor Performance [PDF]
Volume 2A: Turbomachinery, 2015 This paper considers the effect of aspect ratio on compressor performance. It is shown that the aspect ratio at which max efficiency occurs is relatively low, typically between 1 and 1.5. At these aspect ratios, decomposition of the flow field into freestream and endwall flows becomes difficult.

Computation of the marginal contribution of Sharpe ratio and other performance ratios [PDF]
SSRN Electronic Journal, 2021 Computing incremental contribution of performance ratios like Sharpe, Treynor, Calmar or Sterling ratios is of paramount importance for asset managers. Leveraging Euler's homogeneous function theorem, we are able to prove that these performance ratios are indeed a linear combination of individual modified performance ratios.

Within ratio responding during fixed ratio performance [PDF]
Psychonomic Science, 1968 Five rats were trained in steps from FR 10 to FR 120 or FR 160. Response rate increased to a maximum between FR 40 or FR 80 although the reinforcement frequency continually declined from FR 10 to higher ratios. Measurement of interresponse times revealed that changes in within ratio responding were inversely correlated with changes in response rate.

Urban Environment and Solar PV Performance: The Case of the Netherlands
Energies, 2018 The modern urban landscape creates numerous challenges for the deployment of solar Photovoltaic (PV) technology. The large structures that dominate the skyline of every city create compactness, which, in turn, limits the available rooftop area and ...
