Rapid application development
A system to enables Rapid Application Development (“RAD”) is provided. The system provides an object model of an ERP application, which enables software developers to customize the ERP applications. The object model provides a base class that is inherited by each object class. The base class provides an invoke function that is implemented by each object class. During compilation, the RAD system compiles each invocation of a function of an object into a call to a dynamic component passing an identifier of the object, an identifier of the function to be invoked, and the parameters to be passed to the function. The RAD system dynamically compiles, assembles, and instantiates object classes as needed. Because objects are bound at runtime, rather than at compile time, when the source code of an object is modified, the entire ERP application does not need to be recompiled into monolithic IL code and the compilation of object classes is deferred until an object of that class is needed during runtime. The object model thus significantly decreases the time required to customize and extend an ERP application according to the needs of an individual customer. |

Compact, portable, and efficient representation of a user interface control tree
A non-tree representation of a UI control tree is provided by a compact UI binary file that is generated by encoding a UI definition markup file expressing UI controls and behavior in human-readable form. The UI binary file is utilized in a runtime environment on a computing device as a source of a binary instruction stream. The stream can be efficiently processed by an interpreter on the device without needing validation between loading and rendering the UI. The encoding places much of the representation into an object and script section of the UI binary file. The interpreter runs this section without it being entirely resident in the device's memory to minimize the memory footprint. At runtime, operation code (“op-code”) streams contained in this section are used to build UI objects, and implement scriptable behavior for manipulating the UI objects to render the UI on the device with the designed behavior. |

Semi-sequential Galois Field multiplier and the method for performing the same
Disclosed are a semi-sequential Galois field GF(2n) multiplier and the method thereof. The GF(2n) multiplier comprises two ground field multipliers over GF(2m), at least a constant multiplier, and multiple GF(2m) adders. The high-order and low-order elements from a composite field GF((2m)2) for one operand of one GF(2n) multiplication are inputted in parallel into the two ground GF(2m) multipliers, respectively. The high-order and low-order elements from the composite field of another operand of the GF(2n) multiplication are sequentially inputted into the two ground GF(2m) multipliers. As such, multiple partial products are generated. The constant multiplication and additions are performed on the multiple partial products through the constant multiplier and the GF(2m) adders. This generates a high-order element and a low-order element of the composite field GF((2m)2). After mapping these two elements of GF((2m)2) back to GF(2n), the GF(2n) multiplication is done. |

Sparse-coded look-up table
A look-up table (LUT) is arranged as a plurality of rows each indexed by an index value and storing at least a coefficient for each index value for use in processing digital data. The LUT contains repeated sections in which m coefficients stored for successive index values form a cycle. The number m is not an integer power of 2. For example the LUT may be used when converting a digital count to a gain in dB, in which case m may be 6 or 12, the coefficients representing dB or fractional-dB steps in gain. The LUT contains n additional blank rows inserted after every repeated section of m rows storing the cycle of m coefficients, n being 1 or more and (m+n) being an integer power of two (such as 8 or 16). By feeding an initial index value through encoding logic which takes account of the additional rows, it can be ensured that these are never indexed. Thus, a sparse-coded LUT is provided. Although each repeated section is increased in size, the actual size of the LUT in terms of circuit area or programming logic is reduced because the repeating length is now a power of two. |

Systems and methods for validating design meta-data
A metadata validation process that allows for deferring object model validation until after the objects are created. The process also allows for multi-threaded processing of the validation rules, thus increasing overall performance. Validation is performed by enforcing a series of validation rules on an appropriate subject. Rules are specified according to the subject that they are validating (i.e., attribute level, association level, object level or collection level). The metadata driven validation process implements several validation types on different validation units. Correctness validation rule types ensure that a validation unit satisfies all semantic rules defined for it. Completeness validation rule types ensure that a validation unit contains all the necessary data and is ready for further use. At design time, only correctness type validation is performed. Thus, the present invention advantageously allows for incomplete objects to be created at design time. The developer, however, in this case may opt to perform completeness validation at any time. In general, a developer may opt to perform completeness and/or correctness validation at any time independent of deployment processing. In another aspect, full validation (e.g., completeness and correctness) is automatically performed on the objects during the process of creating a configuration prior to deployment. |

System and method for the calibration of a scoring function
A system and method for calibrating a scoring function. The scoring function S(input, classification) provides a score based on the amount of evidence a particular input has in connection with a particular classification. For example, a street level image may be OCR'ed so as to indicate the names of establishments contained within the image, and the scoring function indicates how much evidence exists within the image for a particular establishment. Some establishments (i.e. classifications) may produce higher scores based on the nature of the establishment rather than the nature of the image (i.e. input) causing any ranking of establishments done on the basis of the scoring function to be biased. Accordingly, the scoring function is calibrated by determining the probability distribution of scores for an establishment over a false set of images that do not display the establishment. The scoring function is calibrated so as to adjust the score to overcome such bias. |

Line sharing multipoint pots splitter with intelligent termination
The present invention provides for a system and method for blocking leakage signals and uncoupling connections in a communication system. A leakage signal (LS) blocking splitter employs a high-pass filter which effectively blocks the lower frequency leakage signal. The high-pass filter (an LS filter) has a cut-off frequency selected to fall between the upper range of the leakage signal (which is approximately 4 KHz in the preferred embodiment) and the low-end frequency of a data signal. A detect and terminate function detects service on the communication connection to which each one of the leakage signal (LS) filters are coupled to.

X-ray image formation device
CT imaging is performed twice (S1101), which is set as the normal number of rotations, and a sinogram is corrected (S1102) based on the sinogram obtained by performing CT imaging twice. Since the cycles of data variation caused by respiration are controlled so as not to overlap one another, usually the data variations caused by respiration are eliminated by performing CT imaging twice.

A compensation allocation unit performs allocation compensation of a motion vector to a pixel to which a motion vector is not allocated by a victor allocation unit. A C/UC area determination unit compares magnitudes of a present DFD, a past DFD, and a future DFD based on a background vector and a DFD based on a compensation allocation vector by an evaluation value calculation unit to determine an area of a target pixel. Regarding the target pixel determined as the pixel in a covered area or an uncovered area, an interpolation method decision unit decides a computation method for a pixel value through which one of a double-sided interpolation and a one-sided interpolation. An interpolation frame generation unit computes the target pixel of the pixel value of the interpolation frame through the method decided by the interpolation method decision unit. |
