A delivery unit for providing aggregate to a worksite, such as a wellsite location. The unit may include a mobile chassis for accommodating a plurality of modular containers which in turn house the aggregate. As such, a weight measurement device may be located between each container and the chassis so as to monitor aggregate levels within each container over time. The units may be particularly well suited for monitoring and controlling aggregate delivery during a fracturing operation at an oilfield. The modular containers may be of an interchangeable nature. Furthermore, a preferably wireless control device may be provided for monitoring and directing aggregate delivery from a relatively remote location.

A method and apparatus are disclosed for per-service flow protection and restoration of data in one or more packet networks. The disclosed protection and restoration techniques allow traffic to be prioritized and protected from the aggregate level down to a micro-flow level. Thus, protection can be limited to those services that are fault sensitive. Protected data is duplicated over a primary path and one or more backup data paths. Following a link failure, protected data can be quickly and efficiently restored without significant service interruption. A received packet is classified at each end point based on information in a header portion of the packet, using one or more rules that determine whether the received packet should be protected. At an ingress node, if the packet classification determines that the received packet should be protected, then the received packet is transmitted on at least two paths. At an egress node, if the packet classification determines that the received packet is protected, then multiple versions of the received packet are expected and only one version of the received packet is transmitted.

A method of defining aggregate levels to be used in aggregation in a data store having one or more dimensions. Levels are defined corresponding to attributes in the dimension, so that data can be aggregated into aggregates corresponding to values of those attributes. The invention provides for the definition of sub-levels which act as levels but define which detail entries in the associated dimension will contribute to the sub-level. The invention also provides for the definition of level groups. A level group can replace a level in a level cross-product and such a cross product is then expanded before aggregation into a set of cross products, each containing one of the level group entries.

Congestion within a communication is controlled by rate limiting packet transmissions over selected communication links within the network and modulating the rate limiting according to buffer occupancies at control nodes within the network. Preferably, though not necessarily, the rate limiting of the packet transmissions is performed at an aggregate level for all traffic streams utilizing the selected communication links. The rate limiting may also be performed dynamically in response to measured network performance metrics; such as the throughput of the selected communication links input to the control points and / or the buffer occupancy level at the control points. The network performance metrics may be measured according to at least one of: a moving average of the measured quantity, a standard average of the measured quantity, or another filtered average of the measured quantity. The rate limiting may be achieved by varying an inter-packet delay time over the selected communication links at the control points. The control points themselves may be located upstream or even downstream (or both) of congested nodes within the network and need only be located on only a few of a number of communication links that are coupled to a congested node within the network. More generally, the control points need only be associated with a fraction of the total number of traffic streams applied to a congested node within the network.

A business process modeling framework is used for data quality analysis. The modeling framework represents the sources of transactions entering the information processing system, the various tasks within the process that manipulate or transform these transactions, and the data repositories in which the transactions are stored or aggregated. A subset of these tasks is associated as the potential error introduction sources, and the rate and magnitude of various error classes at each such task are probabilistically modeled. This model can be used to predict how changes in transactions volumes and business processes impact data quality at the aggregate level in the data repositories. The model can also account for the presence of error correcting controls and assess how the placement and effectiveness of these controls alter the propagation and aggregation of errors. Optimization techniques are used for the placement of error correcting controls that meet target quality requirements while minimizing the cost of operating these controls. This analysis also contributes to the development of business “dashboards” that allow decision-makers to monitor and react to key performance indicators (KPIs) based on aggregation of the transactions being processed. Data quality estimation in real time provides the accuracy of these KPIs (in terms of the probability that a KPI is above or below a given value), which may condition the action undertaken by the decision-maker.

A fault injection circuit injects a test signal into a data bus with a normal high logic level and a normal low logic level. The test signal has a greater logic level greater than the normal high logic level of the data bus or a lower logic level lower than the normal low logic level of the data bus. An analog-to-digital converter is coupled to a voltage level detector for sensing an aggregate level of an aggregate signal on the data bus. The aggregate signal is composed of the termination circuit signal and the test signal. A diagnostic tool determines whether a faulty connection between the data bus and a network device exists, where the sensed aggregate level exceeds at least one of the normal high logic level and the normal low logic level.

A novel nuclear receptor, termed the steroid and xenobiotic receptor (SXR), a broad-specificity sensing receptor that is a novel branch of the nuclear receptor superfamily, has been discovered. SXR forms a heterodimer with RXR that can bind to and induce transcription from response elements present in steroid-inducible cytochrome P450 genes in response to hundreds of natural and synthetic compounds with biological activity, including therapeutic steroids as well as dietary steroids and lipids. Instead of hundreds of receptors, one for each inducing compound, the invention SXR receptors monitor aggregate levels of inducers to trigger production of metabolizing enzymes in a coordinated metabolic pathway. Agonists and antagonists of SXR are administered to subjects to achieve a variety of therapeutic goals dependent upon modulating metabolism of one or more endogenous steroids or xenobiotics to establish homeostasis. An assay is provided for identifying steroid drugs that are likely to cause drug interaction if administered to a subject in therapeutic amounts. Transgenic animals are also provided which express human SXR, thereby serving as useful models for human response to various agents which potentially impact P450-dependent metabolic processes.
