  • Publication number: 20240086693
    Abstract: Methods and systems for budgeted and simplified training of deep neural networks (DNNs) are disclosed. In one example, a trainer is to train a DNN using a plurality of training sub-images derived from a down-sampled training image. A tester is to test the trained DNN using a plurality of testing sub-images derived from a down-sampled testing image. In another example, in a recurrent deep Q-network (RDQN) having a local attention mechanism located between a convolutional neural network (CNN) and a long-short time memory (LSTM), a plurality of feature maps are generated by the CNN from an input image. Hard-attention is applied by the local attention mechanism to the generated plurality of feature maps by selecting a subset of the generated feature maps. Soft attention is applied by the local attention mechanism to the selected subset of generated feature maps by providing weights to the selected subset of generated feature maps in obtaining weighted feature maps.

  • Publication number: 20240069063
    Abstract: An on-site reciprocity calibration method for a piezoelectric accelerometer, including a vibration test and a reciprocity test. In the vibration test, a sine excitation with a corresponding frequency and amplitude is provided by a vibration exciting device to the piezoelectric accelerometer fixed on a motion plane, and output signals of a drive port and a signal port of the reciprocal piezoelectric accelerometer are collected by a data acquisition device. In the reciprocity test, a sine voltage excitation is provided by a signal generator to the drive port, and then an excitation signal and an output signal of the signal port are collected by the data acquisition device. An amplitude ratio of the two signals is obtained based on signal sine-fitting. Finally, the on-site calibration is enabled according the sensitivity amplitude ratio obtained in the vibration test and the sensitivity amplitude product obtained in the reciprocity test.

  • Publication number: 20230352349
    Abstract: Embodiments of the present technology may include semiconductor processing methods that include depositing a film of semiconductor material on a substrate in a substrate processing chamber. The deposited film may be sampled for defects at greater than or about two non-contiguous regions of the substrate with scanning electron microscopy. The defects that are detected and characterized may include those of a size less than or about 10 nm. The methods may further include calculating a total number of defects in the deposited film based on the sampling for defects in the greater than or about two non-contiguous regions of the substrate. At least one deposition parameter may be adjusted as a result of the calculation. The adjustment to the at least one deposition parameter may reduce the total number of defects in a deposition of the film of semiconductor material.

  • Publication number: 20220375747
    Abstract: Processing methods disclosed herein comprise forming a nucleation layer and a flowable chemical vapor deposition (FCVD) film on a substrate surface by exposing the substrate surface to a silicon-containing precursor and a reactant. By controlling at least one of a precursor/reactant pressure ratio, a precursor/reactant flow ratio and substrate temperature formation of miniature defects is minimized. Controlling at least one of the process parameters may reduce the number of miniature defects. The FCVD film can be cured by any suitable curing process to form a smooth FCVD film.

  • Patent number: 11155664
    Abstract: Synthesis and characterization of starch based pH-responsive nanoparticles for controlled drug delivery are described. Polymethacrylic acid grafted starch (PMAA-g-St) nanoparticles with various molar ratio of starch to MAA were synthesized by a new one-pot method that enabled simultaneous grafting of PMAA and nanoparticle formation in an aqueous medium. NMR data showed that polysorbate 80 was polymerized into the graft polymer. Nanoparticles were relatively spherical with narrow size distribution and porous surface morphology and exhibited pH-dependent swelling in physiological pH range. The particle size and magnitude of volume phase transition were dependent on PMAA content and formulation parameters such as surfactant levels, cross-linker amount, and total monomer concentration. The results showed that the new pH-responsive nanoparticles possessed useful properties for controlled drug delivery.
