    摘要： A method of estimating a channel response of a channel is provided that includes transforming a frequency domain signal received via the channel into a time domain signal and searching the time domain signal for a location of minimum energy. The method also includes padding the time domain signal with zeroes at the location of minimum energy and transforming the padded time domain signal to a second frequency domain signal. The second frequency domain signal is used as an estimated channel response for the channel.

    摘要： A Digital Radio Mondiale (DRM) receiver and demodulation method includes an analog and digital separation filter for filtering and separating a DRM-encoded signal and a non DRM-encoded signal from a composite RF signal received at the receiver. The DRM receiver includes a programmable downsampler and a programmable N-point Fast Fourier Transform (FFT) to recover and demodulate the OFDM symbols in a received DRM-encoded RF signal. The received signal is digitally sampled at a rate operably integer downsampled to achieve a number N samples in the useful portion of the OFDM symbol for input to an N-point FFT, where N equal to a power of two. The downsampling rate and size (N-points) of the FFT depend on the DRM encoding and transmission parameters, notably the robustness mode and spectrum occupancy. The structure and operation of the receiver in this manner simplifies the design and reduces the required filter order of the analog and digital separation filter.

    摘要翻译： 数字无线电广播（DRM）接收机和解调方法包括模拟和数字分离滤波器，用于从在接收机处接收的复合RF信号过滤和分离DRM编码信号和非DRM编码信号。 DRM接收机包括可编程下行采样器和可编程N点快速傅里叶变换（FFT），以在接收的DRM编码RF信号中恢复和解调OFDM符号。 接收到的信号以可操作的整数下采样的速率进行数字采样，以在OFDM符号的有用部分中实现N个采样，以输入到N点FFT，其中N等于2的幂。 FFT的下采样率和大小（N点）取决于DRM编码和传输参数，特别是鲁棒性模式和频谱占用。 以这种方式，接收机的结构和操作简化了设计，并减少了模拟和数字分离滤波器所需的滤波器顺序。

    摘要： The invention is directed to a menstruum prepositioned type sterile drug-mixing syringe and a menstruum separately positioned type sterile drug-mixing syringe including a shell, a needle, a piston and a push-pull rod assembly. The syringe further includes a menstruum bottle, a solute bottle, a sliding sleeve and a needle loading assembly. The menstruum bottle may be fixed to the inner wall of a sliding sheath, and the solute bottle may be fixed to the inner of the shell. Piston may be disposed within the solute bottle. The sliding sleeve may be socketed to the front end of the shell in advance or disposed by other ways. The mouth of the menstruum bottle may be opposite to the mouth of the solute bottle and may be connected by a needle, which has two piercing tips, wherein the needle punctures and is securely connected to the needle loading assembly.

    摘要： A system for controlling a microgrid includes microgrid assets and a tieline for coupling the microgrid to a bulk grid; and a tieline controller coupled to the tieline. At least one of the microgrid assets comprises a different type of asset than another one of the microgrid assets. The tieline controller is configured for providing tieline control signals to adjust active and reactive power in respective microgrid assets in response to commands from the bulk grid operating entity, microgrid system conditions, bulk grid conditions, or combinations thereof.

    摘要： A “variable group selection” system and method in which constructs are based upon a training data set, a regression modeling module that takes into account information on groups of related predictor variables given as input and outputs a regression model with selected variable groups. Optionally, the method can be employed as a component in methods of temporal causal modeling, which are applied on a time series training data set, and output a model of causal relationships between the multiple times series in the data.
