A software method for controlling the optimization of a planning model that uses historical sales data to predicts optimal prices and similar factors for meeting a number of business goals. Unlike previous systems that allow a user to model prices and other factors based on physical constraints, the present invention allows the optimization to occur against the background of one or more strategic objectives. Such objectives, such a price image, are not set by physical constraints but instead are imposed by the user with the notion that they will provide a strategic and ultimately an economic advantage. The system allows the analysis of the costs and benefits of such management imposed strategic objectives.

A variety of methods for thermal recovery of natural gas and bitumen from a formation containing the latter. In general, the methods incorporate a series of existing, but previously uncombined technologies. A modified flue gas from the steam generators conventionally used in a SAGD recovery operation is injected into the formation to enhance recovery with the produced fluids, natural gas, bitumen, inter alia are further processed. The injection of the flue gas conveniently is disposed of and further acts to repressurize the formation which otherwise becomes depressurized when depleted of natural gas. Accordingly, environmental and economic advantages are realized with the methodology.

The invention relates to a hybrid sub-module MMC (multimedia card) converter with direct-current fault ride-through capability. The hybrid sub-module MMC is similar to the half-bridge MMC in topology, namely a three-phase six-bridge structure, but the single bridge is successively cascaded by m half-bridge sub-modules (HBSM), n full-bridge sub-modules (FBSM) and one clamp dual sub-module (CDSM); the high direct-current voltage utilization rate of FBSM, the direct-current fault current self-cleaning of FBSM and CDSM and the economic advantage of HBSM are integrated to optimally select the amount of m, n and one according to the actual demand, so that the converter can be applied to a flexible direct-current transmission system, in particular, to an occasion with the higher commissioning rate, when the system has one direct-current fault, it is promoted in capacity to save the economic cost under existence of the direct-current fault ride-through capability.

The special feature of this multiphase and multidimensional wave converter is that it exploits, in an efficient and enduring manner, substantially all of the energy in all waves of the sea, also side waves, and hence is capable of producing large amounts of cheap power. The wave converter comprises at least two buoyant elements (1) connected in a chain of rods (2A, 2B) and joints (3, 4). Each single buoyant element is in a different phase of the wave than that of the others. They will therefore absorb the energy from the relative motion and forces between each set of buoyant elements (1). Each of the elements (1) is capable of moving and pivoting in three dimensions whilst the energy from all these motions is exploited. The energy-producing devices may be comprised of fluid-driving pumps (7, 8, 9) responding to the pivoting of the joints (3,4) and the motion of the rods (2A, 2B). The wave converter absorbs energy from a varying wave spectrum and from all directions. The forces affecting the wave converter are balanced by the various buoyant elements (1), thus avoiding transmitting these forces via mooring. The wave converter provides appreciable economic advantages and durability. It may also operate at any place in the sea and the ocean, at shallow depths as well as at the large depths of the ocean.

The present invention is of a cementitious composition containing OPC, calcined gypsum, a source of amorphous silica and a source of amorphous alumina. The ratio of calcium sulfate hemihydrate to OPC is 0.7:1.0 to 1.4:1.0, the ratio of amorphous silica and amorphous alumina to OPC is 0.26:1.0 to 0.4:1.0, and the ratio of amorphous alumina to amorphous silica is 0.3:1.0 to 1.5:1.0. The cementitious composition, by itself and mixed with aggregates, is fast-setting and exhibits good early compressive strength and very high compressive strength after hydration.

A method and apparatus that maintains a database of the demands over time for all the different refurbished machines is disclosed. The invention also maintains the supply over time of all the different machines that will be returned from expired leases. The invention maintains the relationship for alternate parts which parts can be used in place of another. The invention also maintains an inventory of parts and machines. As machines are returned from expired leases, they come into inventory. From this inventory, some of the machines will, from time to time be scheduled to be refurbished or demanufactured. The balance will remain in inventory. When a machine is demanufactured, all of the parts that are produced will be put in inventory. However, some may be used immediately to satisfy a demand for the part and the balance may be used to satisfy demand for the same part later or be used as an alternate part for some other part. The invention also maintains a bill-of-materials that is a cross reference of all the parts that can be produced from each machine. Related to this are parametric data that is required. These data are yields associated with the refurbishing and demanufacturing process, the offset or time required for these processes, the resources required and the capacity of the resource, etc. The final set of information that is maintained by the invention are the priorities of the different demands. These priorities can be time sensitive, if required. These priorities reflect the economic advantage of satisfying one demand before another. For example, demands for refurbished machines may have a high priority, reflecting the consideration that refurbishing generally requires minimal effort and generates a large revenue and profit. Demands (auction/sales) for certain parts sometimes have a high resale value and they would be given a high priority. Finally, most of the other demands (service, sales and auctions) for parts may have a lower priority.
