Abstract: Systems and methods are included for accessing resource objects in a multi-threaded environment. A request is received from a requester to perform an operation with respect to a resource object, where the requested resource object has multiple associations with other objects. A determination as to whether an authorization cache entry corresponding to the requested resource object contains sufficient permission data for granting or denying the request for access to the requested resource object is made. A grant or deny of access to the requested resource object is returned when the authorization cache entry corresponding to the requested resource object contains sufficient permission data.

Abstract: A magnetic photonic crystal for providing asymmetry of spatial frequencies in the propagation of light is provided. The crystal is formed from at least two materials having different indices of refraction which are aligned along the longitudinal axis of the crystal. And arranged in an array whose symmetry does not include a spatial inversion operator such that (x,y)==/=(?x,?y). One or more of the materials forming the array is magnetic such that the magnetic group representation of the array does not include time inversion as a symmetric operator. In operation, when the magnetic material forming the material is magnetized, the group velocity property of light propagated in one direction along the axis of the array is different from the group velocity property of light transmitted in an opposite direction through the array. The magnetic photonic crystal may be used, for example, as an optical memory device or a high speed modulator/demodulator.

The porous cordierite ceramic honeycomb articles has a plurality of cell channels and intersecting porous walls and possess a microstructure characterized by a pore size distribution wherein greater than or equal to 75% of the pore size distribution of the porosity of the porous walls, by volume, have a pore diameter (dv) wherein dv<10.0 ?m and less than or equal to 35% of the pore size distribution have dv?4.0 ?m. Additionally, the pore diameter dv90?14.0 ?m, and CTE?12.0×10?7/° C. from 25° C. to 800° C. The articles exhibits high filtration efficiency coupled with low pressure drop across the filter. Additionally, high porosity articles having porosity greater than or equal to 40% and low surface roughness of Ra<4.0 ?m are described.

Abstract: A ceramic wall-flow filter for filtering particulate matter from gases and methods for manufacturing such wall-flow filters are disclosed. The filter includes an array of porous ceramic walls defining a pattern of end-plugged inlet and outlet cells, and heat absorbing elements disposed within at least some of the outlet cells such that a bulk heat capacity of the outlet cells is greater than a bulk capacity of the inlet cells. The heat absorbing elements increase a bulk heat capacity of the filter without substantially interfering with a flow of gas through the porous ceramic walls by allowing thinner walls. According to the method, during the step of extruding or thereafter, heat absorbing elements are formed within at least some of the outlet cells such that a heat capacity of the outlet cells is greater than the inlet cells.

Abstract: The invention comprises a method for achieving consideration of preemptive priorities within a supply chain optimization model. More specifically, the invention provides a method of allocating resources to a hierarchy of demand priorities in a linear programming production planning system. In particular, the invention aggregates the demand priorities into different priority groups and allocates the resources to the highest priority group of demand priorities using a first linear programming model. Next, the invention allocates remaining resources to the next highest priority group of demand priorities using a second linear programming model. The second linear programming model uses results from the first linear programming model. The invention continues this process by iteratively repeating the process of allocating remaining resources to the remaining groups of demand priorities, in order of priority.

Abstract: The invention provides a method and system for solving a linear program having constraints in a production planning system. The invention first determines which of the constraints can be temporarily relaxed based on stocking point criteria. The stocking point criteria relates to time dependent stocking points that include part numbers, locations of parts identified by the part numbers, and the time periods when the parts will be available. The invention relaxes the constraints that can be relaxed and decomposes the linear program into smaller independent linear programs. The invention initially solves the smaller independent linear programs with relaxed constraints (simultaneously in parallel) to produce an initial solution. Next, the invention replaces variables in the linear program with constants based on this initial solution.

Abstract: Allocating limited manufacturing resources to achieve a feasible production plan that is consistent with customer demand is a difficult and common problem faced in many manufacturing industries. For large-scale multi-stage manufacturing systems, existing methods are typically based either on allocating limited resources sequentially, according to a priority ranked list of production starts, or on linear programming based models. The output of such planning models is a production plan which specifies the quantity of each part to produce at each plant, using resources available to the enterprise. Typically there are lot-sizing rules defining the permissible production start quantities. The invention disclosed herein is a method for applying these rules to the lot-sizing of production starts within a linear program. It employs advanced heuristics that consider both established operational objectives (e.g.

Abstract: A system and method for configuring, sequencing and viewing joins in a query is provided. The system includes an advanced joins viewer that may be invoked from an SQL Query Tool. A graphical user interface associated with the advanced joins viewer displays a sequenced vertical tile list of each table and each intermediate result set in a particular query. Through this interface, a user may re-sequence the ordering of the tables and thus reconfigure the intermediate result sets that are generated by the query. The advanced joins viewer enables the independent configuration of the join type and the join relationships for each of the intermediate result sets. An automatic sequencing algorithm is also provided for configuring the ordering of the tables such that the query produces valid SQL.

Abstract: Disclosed is a method of making a photonic crystal using a combination of extruding and drawing techniques. The method is contemplated as being capable of producing both two and three dimensional crystals due to the maturity and diversity of extruding and drawing technology. The method allows the drawing of relatively large photonic crystals and is flexible enough to provide a periodic array of channels or filaments as the crystal features. After the extruding step or steps and before the step of heating and drawing, a plurality of elongated extruded bodies can be bundled and drawn as a unit.
