Copper-cysteamine and methods of use
Structure and luminescence properties of a new Cu-Cyteamine (Cu-Cy) crystal material are provided. The crystal structure of the Cu-Cy is determined by single crystal X-ray diffraction. It is found that the compound crystallizes in the monoclinic space group C2/c and cell parameters are a=7.5510(4) Å, b=16.9848(7) Å, c=7.8364(4) Å, β=104.798(3)°. The new Cu-Cy crystal material of the invention is also useful for treatment of cancer.Board of Regents, University of Texas Syste
Robust Adaptive Repetitive and Iterative Learning Control for Rotary Systems Subject to Spatially Periodic Uncertainties
This book chapter reviews and summarizes the recent progress in the design of spatial‐based robust adaptive repetitive and iterative learning control. In particular, the collection of methods aims at rotary systems that are subject to spatially periodic uncertainties and based on nonlinear control paradigm, e.g., adaptive feedback linearization and adaptive backstepping. We will elaborate on the design procedure (applicable to generic nth‐order systems) of each method and the corresponding stability and convergence theorems
Robust Adaptive Fuzzy Control for a Class of Switching Power Converters
This chapter provides the reader with a control-centric modeling and analysis approach along with a nonlinear control design for a class of switching power converters. A comprehensive model combining the respective state variable models of the interval subsystems is established. Comparison with PSpice simulation justifies the credibility of the model. Based on this model, internal/BIBO stability can be studied for each interval subsystem. Moreover, controllability and observability can also be analyzed to help determine subsequent control configuration. The established model is further investigated for advanced control design, i.e., robust adaptive fuzzy control
Self organized criticality in an improved Olami-Feder-Christensen model
An improved version of the Olami-Feder-Christensen model has been introduced
to consider avalanche size differences. Our model well demonstrates the
power-law behavior and finite size scaling of avalanche size distribution in
any range of the adding parameter of the model. The probability
density functions (PDFs) for the avalanche size differences at consecutive time
steps (defined as returns) appear to be well approached, in the thermodynamic
limit, by q-Gaussian shape with appropriate q values which can be obtained a
priori from the avalanche size exponent . For the small system sizes,
however, return distributions are found to be consistent with the crossover
formulas proposed recently in Tsallis and Tirnakli, J. Phys.: Conf. Ser. 201,
012001 (2010). Our results strengthen recent findings of Caruso et al. [Phys.
Rev. E 75, 055101(R) (2007)] on the real earthquake data which support the
hypothesis that knowing the magnitude of previous earthquakes does not make the
magnitude of the next earthquake predictable. Moreover, the scaling relation of
the waiting time distribution of the model has also been found.Comment: 16 pages, 6 figure
