To identify the hang, collision and drift faults of methane sensors, this paper presents a fault diagnosis method for methane sensors using multi-sensor information fusion. A methane concentration monitoring approximation model with multi-sensor informati... see more

The Hilbert-Huang transform (HHT) is a method of spectral analysis that is suitable for application to nonstationary and non-linear signals that holds enormous potential for the analysis of turbulent flows in fluvial, aeolian, and coastal systems. HHT beg... see more

The article considers new technique called multimodal pressure flow method that utilizes Hilbert-Huang transformation to quantify interaction between nonstationary cerebral blood flow velocity and blood pressure for the assessment of dynamic cerebral auto... see more

The conversion of time domain data via the fast Fourier (FFT) and Hilbert-Huang (HHT) transforms is compared. The FFT treats amplitude vs. time information globally as it transforms the data to an amplitude vs. frequency description. The HHT is not constr... see more

AbstractHuanglongbing is citrus disease which is a major threat for citrus orchard. Neither disease has a cure nor an efficient means of control. Early detection is important to prevent development and spread of the disease. The most effective detection u... see more

Sampled from the Gangxi oil field in the Huanghua depression, Bohaiwan Basin, the crude oil He and Ar isotopiccompositions and their geochemical significance were investigated. The result shows that i) the 3He/4Hevalues of the six oil samples free from ai... see more

Detection using PCR (Polymerase Chain Reaction) Candidatus Liberibacter asiaticus, Huanglongbing causal Organism on Siem Mandarin with different types of symptoms.  Huanglongbing (HLB) or Citrus Vein Phloem Degeration (CVPD) is one of major diseases ... see more

PM10 samples were collected from Huangshi (HS) city, Central China during April 2012 to March 2013, and were analyzed for short-chain saturated dicarboxylic acids (diacids) using a capillary gas chromatograph (GC). We found that oxalic acid (C2, 318 ± 104... see more
