PREDICTION MODEL FOR DISSOLVED GAS CONCENTRATION IN TRANSFORMER OIL BASED ON MODIFIED GREY WOLF OPTIMIZER AND LSSVM WITH GREY RELATIONAL ANALYSIS AND EMPIRICAL MODE DECOMPOSITION

Oil-immersed transformer is one of the most important components in the power system.The dissolved gas concentration prediction in oil is vital for early incipient fault detection of transformer.In this paper, a model for predicting the dissolved gas concentration in power transformer based on the here modified grey wolf optimizer and least squares

With over one million cases worldwide annually and a high fatality in symptomatic forms, human leptospirosis is a growing public health concern for the most vulnerable populations, especially in the context of global warming and unplanned radio birdman tshirt urbanization.Although the Asia-Pacific region is particularly affected, accurate epidemiol

Borrelia recurrentis, the etiologic agent of louse-borne relapsing fever in humans, has evolved strategies, including antigenic variation, to evade immune defence, thereby causing severe diseases with high mortality rates.Here we identify for the first time a multifunctional surface lipoprotein of B.recurrentis, termed HcpA, and demonstrate that it
