Provided is a generic framework for resource modeling to assist in scheduling tasks. More specifically the model provides a structure and method for receiving a task having at least one resource requirement. Upon receipt of such a task, a set of compliant resources are retrieved. A graph is generated to indicate one or more resource paths, each path running through a subset of the compliant resources. Each resource is represented as a node on the graph, and each resource has at least one characteristic. A characteristic common to all nodes on each path is then selected and plotted upon a continuum. Each path is then evaluated to determine path viability. Path viability is indicated by a common intersection upon the continuum of the selected characteristic for all nodes along the path.

This disclosure describes a technique including operating a redundant disk drive device, wherein the redundant disk drive device includes a primary disk drive and at least one mirror disk drive. At least one of the disk drives is reconfigured within the redundant disk drive system in such a manner that during the reconfiguring, the disk drive is maintained on-line.

The present invention relates to a process for the preparation of substituted alkanesulfonates by the reaction of an aqueous metal substituted 2-hydroxyethanesulfonate with a nucleophile. 2-Alkylaminoalkanesulfonate is formed when the nucleophile is an amine. The invention also relates to the optimization of reaction conditions to produce an optimum yield.

Provided is a workflow engine for managing data. More specifically, the workflow engine includes a receiving subsystem that is operable to receive data. An environment evaluating subsystem is also provided and is operable to evaluate an environment and determine at least one environmental parameter. A data evaluating system is in communication with the receiving subsystem and the environment evaluating subsystem. The data evaluating system is operable to determine at least one data parameter from the received data and to receive the environmental parameter. The data evaluating system will evaluate the data parameter and environment parameter and select at least one appropriate workflow rule for use in establishing a workflow job operation for execution by a job operation subsystem. An associated method of use is also provided.

In an embodiment of the invention, an apparatus and method for detecting resource consumption and preventing workload starvation, are provided. The apparatus and method perform the acts including: receiving a query; determining if the query will be classified as a resource intense query, based on a number of passes by a cache call over a data blocks set during a time window, where the cache call is associated with the query; and if the query is classified as a resource intense query, then responding to prevent workload starvation

A low profile, wide belt mobilized bridge carrier is used in low vein mining operations. The mobilized bridge carrier of the present invention includes a carrier frame that carries the propulsion system and that supports the receiving boom, the discharge boom, the cab assembly and the canopy. The preferred mobilized bridge carrier is track propelled, and includes at least a pair of crawler track assemblies which are actuated by an electrically operated hydraulic motor. The receiving boom and the discharge boom are pinned together and each are pivotally mounted on carrier frame at a main pivot point. The carrier frame is of reinforced construction. The receiving boom and discharge boom of the present invention include low profile side panel assemblies which allow the present mobilized bridge carrier to be used in "low vein" mining applications. In order to compensate for any inherent loss of strength in the receiving boom that results from lowering the profile to accomplish its purpose of operating within low veins, the present receiving and discharge booms incorporate certain novel reinforcements, including inside reinforcement plates that extend substantially throughout the length of the booms and which is constructed of a plate of T1 steel approximately three/fourths of an inch to approximately one inch thick continuously welded to the interior of each of the sides of the booms.
