摘要:
A system and method for estimating sample clock frequency offset (εs) in a digital radio mondiale (DRM) system such as, for example, DRM receivers. The system and method includes using a relationship given by the following equation: ɛ s = linearfit ( angle ( P G m P G_tr m P G m - cycle P G_tr m - cycle ) , l ) × N 2 π × cycle × ( N + L ) wherein the PGm is the gain pilot received in the mth symbol and PG—trm is the gain pilot transmitted in the mth symbol, the PGm-cycle is the gain pilot received in (m-cycle)th symbol, the PG—trm-cycle is the second gain pilot transmitted in (m-cycle)th symbol, the l is the index of the sub-carrier associated with the gain pilot, the N is a factor of a sample point number of a useful symbol, the L is a sample point number of a guard interval, and the cycle is the interval of two symbols which are inserted gain pilots at the same sub-carriers (l).

A manual controller commands a telescope mount to automatically track a specific bright star after the image of the star is located to center of an electronic eyepiece and a timer is started. The average moving speed of the bright star is calculated after a predetermined elapsed time to acquire the right ascension (RA) and the declination (DEC) coordinates of this bright star. Subsequently, the RA and DEC coordinates are compared with pre-stored data contained within a database used to identify the bright star. The celestial sphere coordinates of the telescope can be determined after a minimum of one bright star is identified. In the auto-tracking procedure, the manual controller controls movement of telescope by feedbacks of the drifting speed and direction of the specific bright star in an electronic eyepiece for the purpose of keeping the specific bright star in the center of the electronic eyepiece.

摘要:
A liquid chromatographic system is provided including catalytically combining hydrogen and oxygen gases in the chromatography eluent stream in a catalytic gas elimination chamber, to form water and thereby reduce the gas content in the eluent stream. Also, a liquid ion chromatographic system in which the effluent from the detector is recycled to a membrane suppressor and then is mixed with a source of eluent for recycle to the chromatographic column.
摘要:
The present invention relates to amphiphilic block copolymers comprising at least one block of hydrophilic units and at least one block of hydrophobic units, wherein at least one hydrophobic block contains siloxane units. The present invention may be particularly useful as a tissue adhesive or as a coating for an intraocular lens (IOL). As an IOL coating, copolymers according to the invention may be used, for example, to promote tissue adhesion for the prevention of posterior capsule opacification.
