Proteins from the same family have similar functions. Hence, it is important to discover from a protein family conserved sequence patterns with variations to unveil the functionality of a functional domain. Aligned Pattern Clusters (APCs) are knowledge-rich representations comparing with probabilistic models. If significant aligned residue associations (ARAs) were discovered in APCs, they could reveal...
High-resolution, low-power radiation-tolerant ADCs are under great demand from medical, aerospace and high-energy physics applications. In the ATLAS Liquid Argon Calorimeter of the LHC experiment at CERN, the radiation operation condition coupled with the large dynamic range (>12b ENOB), 40-80MS/s sample rate and low power (for cooling system requirement) specs [1] make the design of such ADCs...
Due to their high electrical resistance and breakdown strengths, the polymeric composites have been widely employed for outdoor insulations. Accurate determination of the dielectric permittivity and loss is crucial to assess the status and service life of electrical apparatus. Dielectric spectroscopy measurement is one of the important techniques in insulation diagnostics. As the contact-free method...
A method for ultrasonic thickness measurement of coatings by Welch power spectrum is described. The multiple reflections of ultrasonic waves in coating layer lead to a series of maximum energy occurred in the Welch power spectrum which can be implemented to evaluate the thickness of coatings. A great of experiments verified it is effective and feasible to test nondestructively coating thickness on...
A magnetic pulse compression topology is presented which does not contain external remagnetization circuits that are commonly used in magnetic compressors. Principle of operation of the compressor is described. A two stage compression system is designed based on the new MPC topology. To understand the magnetic switch operation in great detail and to model the performance of magnetic switches, a Pspice...
