    Abstract: Provided is a quadrature voltage controlled oscillator capable of varying a phase difference between an in-phase output signal and a quadrature output signal. The quadrature voltage controlled oscillator comprises a first voltage controlled oscillator, a second voltage controlled oscillator, a first amplifier, a second amplifier, a third amplifier, and a fourth amplifier. The first voltage controlled oscillator generates a first output and a second output. The second voltage controlled oscillator generates a third output and a fourth output. The first output is a positive in-phase signal, and the second output is a negative in-phase signal. The third output is a positive quadrature signal, and the fourth output is a negative quadrature signal. The first amplifier is controlled by a first current and drives the first output and the second output in response to the third output and the fourth output. The second amplifier is controlled by a second current and drives the first output and the second output in response to the third output and the fourth output. The third amplifier is controlled by a third current and drives the third output and the forth output in response to the first output and the second output.

    Abstract: A moving radar (405) generates a synthetic aperture image from an incomplete sequence of periodic pulse returns. The incomplete sequence of periodic pulse returns has one or more missing pulses. The radar converts the incomplete sequence of pulse returns into a digital stream. A computer (403) processes the digital stream by computing an along track Fourier transform (402), a range compression (408), an azimuth deskew (410) and an image restoration and auto focus (412). The image restoration and autofocus (412) utilizes a low order autofocus (501), a gap interpolation using a Burg algorithm (503), and a high order autofocus (505) for generating an interpolated sequence. The interpolated sequence contains a complete sequence of periodic pulse returns with uniform spacing for generating the synthetic aperture image. The image restoration and autofocus (412) computes a linear prediction coefficients estimate using the Burg Algorithm (606). The linear prediction coefficients estimate (606) is used to compute a weighted forward-backward interpolation to generate the complete sequence of periodic pulse returns (608).

    Abstract: The present invention relates to a method for producing lactic acid with high concentration and high yield using Lactobacillus paracasei CJLA0310 KCCM-10542 that is separated and identified from Kimchi. Lactic acid is a very important organic acid with a wide range of applications including food additive such as food preservative, condiment or acidifier, and industrial fields such as cosmetics, chemistry, metals, electronics, fabrics, dyeing textiles, and pharmaceutical industries. Particularly, lactic acid is an essential ingredient of polylactic acid, one of biodegradable plastics to replace recalcitrant non-biodegradable plastics which are main causes of environmental contamination.
