Abstract As an important renewable energy source, wind power generation is highly stochastic and uncertain due to various environmental factors affecting its output.To raise the accuracy of wind power generation prediction, a bidirectional long short-term memory network combination model based on sparrow search algorithm and firefly algorithm optim
This paper theoretically deals some aspects related to Differential Item Functioning (DIF), consisting of Test and Test Bias.The purpose of this is to Beavis and Butthead describe the importance of understanding Different Item Functioning or to discuss its existence.Based on the theoretical connotation of DIF, it can be inferred that DIF may be use
Munchausen syndrome by proxy (MSBP) is emerging Hockey Skates - Intermediate - Rec as a serious form of child abuse.It is an intentional production of illness in another, usually children by mothers, to assume sick role by proxy.It is poorly understood and a controversial diagnosis.Treatment is very difficult.We present a case of 9-year-old boy bro
A blind intrapulse modulation recognition based on energy focusing efficiency test was proposed, which can be Tools used to estimate the modulation type under low signal to noise ratio (SNR) conditions.The observed signals were pre-processed by short time filter defined in frequency domain in order to improve the processing SNR.Then, energy focus-i
