摘要： An implementation of NMF functionality integrated into a relational database management system provides the capability to apply NMF to relational datasets and to sparse datasets. A database management system comprises a multi-dimensional data table operable to store data and a processing unit operable to perform non-negative matrix factorization on data stored in the multi-dimensional data table and to generate a plurality of data tables, each data table being smaller than the multi-dimensional data table and having reduced dimensionality relative to the multi-dimensional data table. The multi-dimensional data table may be a relational data table.

摘要： An improvement reducing or eliminating noise between drivers connected in common on a single chip. A DC power source (VDD1) providing a common signal to multiple PCML drivers and inductance introduced between a common DC power source and each of the multiple PCML drivers tied in common to the DC power source. The introduced inductance between VDD1 and each of the multiple PCML drivers reduces or eliminates AC noise from flowing between drivers and allows DC signaling to pass to all drivers commonly connected to VDD1.

摘要： The invention is directed toward a lapping apparatus and method for accurately obtaining the height of a magnetoresistive (MR) element of a magnetic head during a lapping process. The apparatus includes a source for inducing a magnetic excitation field, and a current source for applying a sense current to a prepatterned photolithographically formed MR element. A sensor monitors the resistance of the MR element in response to variations in the magnetic excitation field, and controls the lapping process in response to the monitored resistance of the MR element. In one embodiment, the MR element includes a GMR formed of a stack of parallel MR layers and operates either in a CPP (Current-Perpendicular-to-the Plane) mode or in a CIP (Current-In-the Plane) mode. In a particular embodiment, the magnetic excitation field is generated by a conductor formed on the magnetic head.

摘要： A resistive capacitor structure adding series resistance to a decoupling capacitor for improved decoupling of power and ground plane noise signals. The resistive capacitor couples a resistor in series with the capacitor where the resistor provides high resistance without substantially increasing inductance to thereby dampen anti-resonance noise typically generated when multiple decoupling capacitors are used for filtering a broader range of possible noise signal frequencies. In one aspect, the resistor comprises magnetic material or other low conductivity material, such as iron, having a small skin depth characteristic to thereby reduce the inductance while still providing high resistivity required to dampen anti-resonance noise. The resistive element may be discrete with respect to the decoupling capacitor or may be integral therewith as one of the plates of the decoupling capacitor. The resistive capacitor plates may be integral with and form a part of the power and ground planes of a circuit board.

摘要： A computer-assisted method for placing each of a plurality of observations into one of a predefined set of clusters is disclosed. The disclosed method includes, for each of a plurality of observations, obtaining a data set containing no more than one proxy value for each of a plurality of variables, each variable having a plurality of possible values, and obtaining a set of first dummy variables having a value indicative of an observation's membership or non-membership (i.e., membership status) in a particular cluster. The disclosed method also includes obtaining a set of second dummy variables each having a value indicative of an observation's having a particular response or lack thereof for a given variable, and, for each observation, regressing the set of first dummy variables on the set of second dummy variables to obtain a linear approximation to a plurality of probabilities that an observation with particular provided values to the plurality of possible values belongs to each particular cluster from the predefined set of clusters.
