A method and apparatus for clustering data, particularly regarding an image, that constructs a graph in which each node of the graph represents a pixel of the image, and every two nodes represent neighboring pixels associated by a coupling factor. Block pixels are selected with unselected neighboring pixels coupled with a selected block to form aggregates.

Saliency of segments is detected in the pyramid, and by computing recursively, a degree of attachment of every pixel to each of the blocks in the pyramid. The pyramid is scanned from coarse to fine starting at the level a segment is detected, to lower levels and rebuilding the pyramid before continuing to the next higher level. Relaxation sweeps sharpen the boundaries of a segment.

System and apparatus for using block-level sampling for histograms construction as well as distinct-value estimations. For histogram construction, the system implements a two-phase adaptive method in which the sample size required to reach a desired accuracy is decided based on a first phase sample. This method is significantly faster than previous iterative block-level sampling methods proposed for the same problem. For distinct-value estimation, it is shown that existing estimators designed for uniform-random samples may perform very poorly with block-level samples. An exemplary system computes an appropriate subset of a block-level sample that is suitable for use with most existing estimators.

A low density parity check (LDPC) code that is particularly well adapted for hardware implementation of a belief propagation decoder circuit is disclosed. The LDPC code is arranged as a macro matrix (H) whose rows and columns represent block columns and block rows of a corresponding parity check matrix (H_pc). Each non-zero entry corresponds to a permutation matrix, such as a cyclically shifted identity matrix, with the shift corresponding to the position of the permutation matrix entry in the macro matrix. The block columns of the macro matrix are grouped, so that only one column in the macro matrix group contributes to the parity check sum in any given row. The decoder circuitry includes a parity check value estimate memory which may be arranged in banks that can be logically connected in various data widths and depths. A parallel adder generates extrinsic estimates that are applied to parity check update circuitry for generating new parity check value estimates. These parity check value estimates are stored back into the memory, and are forwarded to bit update circuits for updating of probability values for the input nodes. Variations including parallelism, time-sequencing of ultrawide parity check rows, and pairing of circuitry to handle ultrawide code rows, are also disclosed.

A web-based hosted solution through which application developers create, manage and monitor application usage analytics in an online manner. Preferably, an application under test is one of: application software, a script-enabled web application, or a rich Internet application (RIA). During the development process, a usage monitoring API is integrated into the application and the application is deployed. As users interact with the application, a log file is generated, typically in one of two ways. If the application is able to write to a local file system (in the user's machine), usage information is gathered in a log file local to the deployed application and then dispatched to an upload server for processing in a batch manner. If the application is not able to write to the user machine's local file system, the usage information is sent to a remote logging server, preferably on a just-in-time basis, and then the log file is generated on the logging server. In either case, preferably the usage information that is tracked comprises “features,”“faults” and “failures” of the application, independent of platform, location, and number of deployed application instances.

To facilitate construction of an hydraulic dam, a water fillable barrier has a tubular water fillable portion with a tongue projecting from one end. The tongued end of the barrier may abut the tubular sidewall of a second such water fillable barrier with the tongue wrapped around the second barrier and lashed to the first barrier. This arrangement allows the effective construction of a corner in an hydraulic dam. To extend the length of the dam, opposed ends of each of two end-to-end water fillable barriers may be overlapped within a sleeve. When the barriers are then filled with water, they foreshorten. This pulls the overlapping portions back in order to form a high pressure end-to-end abutment between the barriers.
