  • Publication number: 20110315599
    Abstract: An integrated process for producing naphtha fuel, diesel fuel and/or lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur and/or nitrogen conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. The sour feed can be delivered to a catalytic dewaxing step without any separation of sulfur and nitrogen contaminants, or with only a high pressure separation so that the dewaxing still occurs under sour conditions. Various combinations of hydrotreating, catalytic dewaxing, hydrocracking, and hydrofinishing can be used to produce fuel products and lubricant base oil products.

  • Publication number: 20110317590
    Abstract: A networking device includes a hardware port coupled to a first device and a management module. The management module identifies fabric subsets such that devices included in a fabric subset are permitted to communicate with each other, identifies configurations that include subsets that are active when the configuration is active, and detects that a device is uncoupled from the port. In response to detecting, the management module modifies the subsets by creating a new subset that does not include the uncoupled device, and modifies the configurations.

  • Publication number: 20110314217
    Abstract: This Sampling Object Cache System (“SOCS”) estimates the size of an in-memory heap-based object cache without the need to serialize every object within the cache. SOCS samples objects at a user-determined rate and then computes a “sample size average” for each type of class—whether a top class, type of top class or non top class. Using these sample size averages, a statistically accurate measure of the overall size of the cache is calculated by adding together the total size of the objects in the cache for each class type.

  • Publication number: 20110298008
    Abstract: A low energy surface is formed by a high temperature anneal of the surfaces of trenches on each side of a gate stack. The material of the semiconductor layer reflows during the high temperature anneal such that the low energy surface is a crystallographic surface that is at a non-orthogonal angle with the surface normal of the semiconductor layer. A lattice mismatched semiconductor material is selectively grown on the semiconductor layer to fill the trenches, thereby forming embedded lattice mismatched semiconductor material portions in source and drain regions of a transistor. The embedded lattice mismatched semiconductor material portions can be in-situ doped without increasing punch-through. Alternately, a combination of intrinsic selective epitaxy and ion implantation can be employed to form deep source and drain regions.

  • Publication number: 20110301907
    Abstract: Systems and methods provide acceleration of automatic test pattern generation in a multi-core computing environment via multi-level parameter value optimization for a parameter set with speculative scheduling. The methods described herein use multi-core based parallel runs to parallelize sequential execution, speculative software execution to explore possible parameter sets, and terminate/prune runs when the optimum parameter value is found at a previous level. The present invention evaluates the design prior to the implementation of the compression IP so that it can define the configuration of DFT and ATPG to maximize the results of compression as measured by test data volume and test application time.

  • Publication number: 20110302127
    Abstract: A method of computing a measure of similarity between nodes of first and second networks is described. In particular, sets of pairwise scores are computed to find nodes in the individual networks that are good matches to one another. Thus, a pairwise score, referred to as Rij, is computed for a node i in the first network and a node j in the second network. Similar pairwise scores are computed for each of the nodes in each network. The goal of this process is to identify node pairs that exhibit high Rij values. According to the technique described herein, the intuition is that nodes i and j are a good match if their neighbors are a good match. This technique produces a measure of “network similarity.” If node feature data also is available, the intuition may be expanded such that nodes i and j are considered a good match if their neighbors are a good match (network similarity) and their node features are a good match (node similarity). Node feature data typically is domain-specific.

  • Patent number: 8072044
    Abstract: Methods for singulating a semiconductor wafer into a plurality of individual dies that contain lateral edges or sidewalls and the semiconductor dies formed from these methods are described. The dies are formed from methods that use a front to back photolithography alignment process to form a photo-resist mask and an anisoptropic wet etch in an HNA and/or a TMAH solution on the backside of the wafer through the photoresist mask to form sloped sidewalls and/or textures. The conditions of the TMAH etching process can be controlled to form any desired combination of rough or smooth sidewalls. Thus, the dies formed have a Si front side with an area larger than the Si backside area and sidewalls or lateral edges that are not perpendicular to the front or back surface of the die. Other embodiments are also described.

  • Publication number: 20110295978
    Abstract: Methods, systems and devices provide mechanisms and systems for efficiently delivering files over a broadcast system to mobile devices. Files for broadcast may be logically identified as belonging to a directory in a file system. A Broadcast Schedule Message may inform receiver devices of files that will be broadcast at a specified time, as well as describe the files. File may be transmitted in file delivery pipes, which may be of different bandwidth and data rates. Receiver devices configured according to the embodiments may make use of the broadcast schedule message to select files to be received based on the service or application with which the file is associated, and whether the file is new or an update to a previously received file. Receiver devices activate receiver circuitry to capture the files within their advertised broadcast window, and pass the received files to applications or services requesting the files.
