The exploration by the in-situ measurement in the stratosphere, approximately 8–50 km height, can be done by sounding balloons exclusively. The scientific sounding balloon was used in the past decades to carry up to tones of the scientific instruments to the upper atmosphere and reached a great contribution in the atmosphere science, space science, and astrophysics. But the large scientific balloon...
Isocyanate-terminated polydimethylsiloxane (ITPDMS) was synthesized by the reaction of Hydroxyl-terminated polydimethylsiloxane (HTPDMS) with Toluene diisocyanate (TDI) and was used to modify epoxy resin (Diglycidyl ether of bisphenol A epoxy resin (DGEBA)). The chemical structure of ITPDMS and ITPDMS/ER was characterized by FTIR. The morphology of fracture surfaces of the ITPDMS/ER cured samples...
Linear discriminant analysis (LDA) is designed to seek a linear transformation that projects a data set into a lower-dimensional feature space for maximum class geometrical separability. LDA cannot always guarantee better classification accuracy, since its formulation is not in light of the properties of the classifiers, such as the automatic speech recognizer (ASR). In this paper, the relationship...
