System and method for accelerated dynamic data message generation and transmission
The speed of generating and transmitting electronic messages to one or more recipients over a communication link is dramatically increased. When processing a new outgoing message for transmission, the system identifies one or more portions of the message as belonging to a particular category included in a number of predetermined types of values. For each portion that is not already present in a category, the corresponding value is obtained and stored along with the message portion in the category. For each outgoing message that includes one portion that matches one or more of the portions stored, the system uses the stored values for the matching message portions of the outgoing messages, instead of performing processing on those message portions. Thus, instead of processing an entire outgoing message for transmission, the system only needs to process the portion of the message that is not found in any of the categories.

Conflict fast consensus
A conflict tolerant message delay reducing consensus algorithm is presented for operating a distributed computing system. The devices of the distributed computing system can directly receive client requests, and can execute the requests and respond directly to the clients, saving message delays. If there is a conflict, the ultimately selected request can be the request submitted by the client with the highest client identifier. A device can change its vote, and execute a different request, if it is made by a client having a more dominant client identifier. All but one of the clients can also be a device implementing the system. A device that has executed a requested function may no longer submit a request in the same step. Consequently, a request is executed by the system when all devices have executed the request. If one or more devices fails, any fault tolerant consensus algorithm can be used.

Identifying relevant portions of a document
Apparatus and associated systems, methods, and computer program products relate to identifying types of search query terms based on the location of information that matches the search query terms. The query terms may be assigned weights according to the query type. The assigned weights may be used, in conjunction with a scoring rule, to determine a score that indicates how relevant blocks of information in the selected document are to the search query terms. In one example, query terms that are located in the title or the URL information associated with a document are classified as a query type that is assigned little or no weight. In this way, relevance scoring within a document may be improved by discounting the influence of query terms that are likely to be primarily meaningful for locating (i.e., navigating to) a relevant document, but less meaningful for locating relevant information within a document.

In addition, frequencies of domain appearance are determined for search results retrieved for queries associated with a category. Domains that appear more frequently in the search results corresponding to the category are identified as expert domains for the category. A user may be allowed to customize expert domains related to one or more categories by adding or removing expert domains for the category.
Decentralized, distributed internet data management
In a light-weight transactional system architecture, each component providing a service performs its own scheduling and transaction management. An invocation of one of these services (through remote method invocation) results in the creation of a local transaction (child of the invoking transaction and parent of any transaction that might be triggered by invoking the services of other servers). The information that is required to build a global composite transaction is implicitly added by the system to each call. Each transaction is, however, independently handled at each server. That is, the servers neither communicate among themselves nor rely on a centralized component to make scheduling or recovery decisions. In this way, components can be dynamically added or removed from the system without compromising correctness. Regardless of the configuration, the system according to the invention guarantees that transactions executed over these servers are correct and recoverable at a global and local level.

Modeling and verification of concurrent systems using SMT-based BMC
A computer implemented method for modeling and verifying concurrent systems which uses Satisfiability-Modulo Theory (SMT)-based Bounded Model Checking (BMC) to detect violations of safety properties such as data races. A particularly distinguishing aspect of our inventive method is that we do not introduce wait-cycles in our symbolic models for the individual threads, which are typically required for considering an interleaved execution of the threads. These wait-cycles are detrimental to the performance of BMC. Instead, we first create independent models for the different threads, and add inter-model constraints lazily, incrementally, and on-the-fly during BMC unrolling to capture the sequential consistency and synchronization semantics. We show that our constraints provide a sound and complete modeling with respect to the considered semantics. One benefit of our lazy modeling method is the reduction in the size of the BMC problem instances, thereby, improving the verification performance in both runtime and memory.
Automated field development planning of well and drainage locations
A hybrid evolutionary algorithm (“HEA”) technique is described for automatically calculating well and drainage locations in a field. The technique includes planning a set of wells on a static reservoir model using an automated well planner tool that designs realistic wells that satisfy drilling and construction constraints. A subset of these locations is then selected based on dynamic flow simulation using a cost function that maximizes recovery or economic benefit. In particular, a large population of candidate targets, drain holes and trajectories is initially created using fast calculation analysis tools of cost and value, and as the workflow proceeds, the population size is reduced in each successive operation, thereby facilitating use of increasingly sophisticated calculation analysis tools for economic valuation of the reservoir while reducing overall time required to obtain the result. In the final operation, only a small number of full reservoir simulations are required for the most promising FDPs.

Self-calibrated azimuth and attitude accuracy enhancing method and system (SAAAEMS)
A method and system for Self-calibrated Azimuth and Attitude Accuracy Enhancing are disclosed, wherein SAAAEMS approach is based on fully auto-calibration self-contained INS principles, not depending on magnetometers for azimuth/heading determination, and thus the system outputs and performance are not affected by the environmental magnetic fields. In order to reduce the system size and cost, this new innovative methods and algorithms are used for SAAAEMS system configuration and integration. Compared to a conventional INS for gyrocompassing, AGNC's approach uses a smaller number of high accuracy sensors: SAAAEMS uses only one 2-axis high accuracy gyro (for example, one DTG) instead of 3-axis; the third axis gyro is a MEMS gyro. It uses only 2 high accuracy accelerometers instead of 3, since the two accelerometers are used only for gyrocompassing not for navigation. These two changes to the conventional INS system configuration remarkably reduce the whole system size and cost. SAAAEMS, uses dynamic gyrocompassing processing for isolation of Base motion disturbance/interference and vibration. SAAAEMS provides a method and system for using automatic methods for system calibration.

Method and apparatus for generation and transmission of high energy optical pulses for long range measurements
A method and apparatus for generating and transmitting high energy optical pulses are described. Distributed temperature sensors usually use Raman scattering in optical fibers as the means to determine the temperature. Here, light from a laser source is sent down a fiber and the small amount of light that is scattered back towards the source is analysed. As the fiber length increases, the resolutions of the temperature and loss measurements become poorer. This is because losses in an optical fiber attenuate the signal. An obvious solution to this problem is to launch more light into the fiber to compensate for the losses but stimulated Raman scattering limits how much light may be launched. The present invention solves this problem by using a pulse conversion method to maximize the resultant pulse energy while the power is kept below SRS threshold.
Weight-adjusted module and method
A weight-adjusted method applied in adjusting a weighting coefficient in an image scaling process. First, an absolute difference is obtained by taking an absolute value of a difference between a first pixel value and a second pixel value of an image. Next, the absolute difference is compared with several threshold values, which define several zones, so as to generate a weight-adjusted value corresponding to a zone in which the absolute difference falls. After that, a first pixel weighted value and a second pixel weighted value are adjusted according to the weight-adjusted value. Finally, a weighted pixel value is outputted by adding a product of the first pixel value and a first adjusted pixel weighted value to a product of the second pixel value and a second adjusted pixel weighted value.

If so, the concealed object is re-mosaicked with an adequate re-mosaic block size. With this, even for a reduced image reduced by lowering the resolution of the original image in which the object to be concealed is mosaicked, the privacy of the concealed object can be protected.

The DDPD engine is implemented as a composite of one linear filter and N−1 high order term linear filters. The bank of linear filters have programmable complex coefficients. To compute the coefficients, samples from the transmit path and a feedback path are captured, and covariance matrices A and B are computed using optimized hardware. After the covariance matrices are computed, Gaussian elimination processing may be employed to compute the coefficients. Mathematical and hardware optimizations may be employed to simplify and reduce the number of multiplication operands and other operations, which can enable the DDPD system to fit within a single chip.

According to the invention, a method of arbitration in a network on an integrated circuit is provided, the network comprising a router unit, the router unit comprising a first input port, a second input port and an output port, wherein the router unit receives at least one first packet via the first input port, and wherein the router unit receives at least one second packet via the second input port, the router unit arbitrating between the first packet and the second packet, characterized in that the step of arbitrating is performed using a first label and a second label, the first label being attached to the first packet, and the second label being attached to the second packet. This method relies on the perception that the arbitration performed by a router should be based on connection arbitration instead of input port arbitration. This means that instead of merely arbitrating between the contending input ports in a router, the arbitration should also take into account the connections to which packets correspond. This can be done by attaching labels to the packets, which labels are used in the arbitration process. In this way, it is possible to achieve a fair allocation of bandwidth to different connections, regardless of on which input ports these connections are established.
