Short-Term Photovoltaic Power Prediction Based on Standard Clear Sky Set Defined by No Climbing Event

Zhongguo dianli, 2023
Photovoltaic power output is influenced by season, weather conditions, and other factors with randomness and uncertainty. It is difficult to predict the power output under bad weather with strong volatility.

Sample Selection Based on Active Learning for Short-Term Wind Speed Prediction

Energies, 2019
Wind speed prediction is the key to wind power prediction, which is very important to guarantee the security and stability of the power system. Due to dramatic changes in wind speed, it needs high-frequency sampling to describe the wind.

Long-term blood-sampling technique in piglets [PDF]

Laboratory Animals, 1986
A technique to enable long-term blood sampling from piglets aged 2-3 months is described. Piglets were housed individually in expandable cages and a heparinized polyurethane catheter was inserted into the external jugular vein. A technique was used which prevented the catheter from pulling out of the vein with growth of the animals.

The mechanical latching memory of an adhesive tape

New Journal of Physics
The storage and retrieval of mechanical imprints from past perturbations is a central theme in soft matter physics. Here we study this effect in the partial peeling of an ordinary adhesive tape, which leaves a line of strong adhesion at the stopping ...

Long-Term Strategic Asset Allocation: An Out-of-Sample Evaluation [PDF]

SSRN Electronic Journal, 2011
We evaluate the out-of-sample performance of a long-term investor who follows an optimized dynamic trading strategy. Although the dynamic strategy is able to benefit from predictability out-of-sample, a short-term investor using a single-period market timing strategy would have realized an almost identical performance.
