The brushless DC motor (BLDCM) with trapezoidal electromotive force (back-EMF) waveform is used widely.
Important parameters of antennas, such as antenna bandwidth, radiation waveform and cross coupling determine the GPR system performance.
To avoid having a seriously distorted waveform, the distance between inner and outer radii of the rotor must be larger than 1.5 millimeter.
The results show that an actuator excited by fixed-frequency and the adjustable-amplitude ramp voltage waveform works with a large travel range (180°), high resolution (1 μrad), speed (0.2 rad/min) and heavy-load ability (0.02 Nm).
The spectrometer consists of a thin CsI(Tl) crystal, an ФЭУ-176 photomultiplier, and a waveform digitizer.
Effect of Alleles Wv and Wy of the Dominant White Spotting Mutation on the Preimplantation Development of Mice
We proposed a new procedure to classify human tumor samples based on microarray gene expressions by using a hybrid supervised learning method called MOEA+WV (Multi-Objective Evolutionary Algorithm+Weighted Voting).
MOEA is used to search for a relatively few subsets of informative genes from the high-dimensional gene space, and WV is used as a classification tool.
The weaver (wv) mutant mouse is a commonly used model for studying hereditary cerebellar ataxia and provides us with an opportunity to study the function of IGF-I in postnatal growth during neurodegeneration.
In prepubertal wv mice, we found a parallel decrease in body weight and serum IGF-I.
