摘要： A method can include determining a number of cases received (e.g., a case load), a number of cases processed (e.g., a case rate), and dividing the case load by the case rate. The resource demand can be compared to a resource allocation, and the resource allocation can be changed based upon the resource demand. A information handling system can include a processor and a memory. The memory can have code stored therein, wherein the code can include instructions, which, when executed by the processor, allows the information handling system to perform part or substantially all of the method.

摘要： The invention determines whether any asynchronous signals are pending and then delivers any such pending signals to the emulated application before the control is transferred to the operating system. A first mechanism sets a global flag, and checks to determine if any signals are pending. If there are pending signals, the emulator halts the emulation of the system call, and delivers the signal to the emulated application. A second mechanism handles signals that arrive after the first mechanism has performed its check. This mechanism checks to see if the global flag is set when a signal arrives. If the flag is set, then the signal is delivered immediately. If the flag is not set, then the signal is deferred. A third mechanism establishes a watch state at the beginning of the emulation, which would be changed by any action of the operating system. When a signal comes in, the emulator checks the watch state. If it does not exist, then the emulator defers the system call.

摘要： An efficient and economical process for the waste treatment of spent metal plating solutions, primarily spent electroless nickel solutions, to significantly reduce the metal content therein, so as to permit direct discharge to municipal water systems without violation of the law. The waste treatment process is a sequential two-step chemical precipitation process, whereby the dissolved metal content is precipitated first by sodium borohydride reduction, followed by sodium dimethyldithiocarbamate precipitation, with an intermediate filtration step and pH adjustment step interposed there between. The amount of metal-bearing sludge produced is minimal. Furthermore, the bulk of the metals in the sludge may be recovered and reused, resulting in significant reduction in hazardous waste disposal costs.

摘要： A method and article of manufacture for providing a balanced tradeoff between size of a single binary file and performance of that binary on various computer architectures of a wide range of computer platforms. The invention includes identifying performance critical source code and complementary source code having less performance criticality than the performance critical source code. The performance critical source code is compiled so as to generate performance critical object code for a first computer architecture, or an additional plurality of computer architectures as desired. The complementary source code is compiled so as to generate complementary object code for a particular computer architecture, selected as a generic computer architecture, which is different than at least one of the plurality of computer architectures. Subsequent storage on a computer usable medium such as a floppy disk provides for convenient distribution of computer readable program code, preferably embodied in a single architecture independent executable binary file that includes the performance critical object code for the plurality of computer architectures, as well as the complementary object code. The complementary object code has less performance criticality than the performance critical object code so as to reduce overall performance effects of subsequent translation of the complementary code to any desired computer architecture.

摘要： Carbothermally reduce a metal oxide to its corresponding metal nitride or metal carbide powder in a vertical gravity flow reactor by adding precursor pellets containing the metal oxide, a thermally decomposed binder material and carbon or a source of carbon directly to a heated reaction zone within the reactor. The pellets form a pellet bed, the top of which must be maintained within the heated reaction zone. The binder material is a blend of wheat and corn starches, optionally in conjunction with another binder such as melamine. The binder material thermally decomposes to a carbonaceous residue which functions both as an additional source of carbon and as a binder for the precursor pellets. The reactor may be modified by adding an internal vent line to remove volatile materials from the heated reaction zone before they have an opportunity to condense on internal reactor surfaces.

摘要： A method is disclosed for purifying aluminum nitride produced by carbothermal reaction of aluminum oxide, carbon and nitrogen. Precursor pellets including aluminum oxide and carbon are exposed to nitrogen under conditions sufficient to carbothermally produce aluminum oxide, thereby producing aluminum nitride pellets having surface portions relatively rich in thermal conductivity-lowering and color-causing impurities compared to core portions of the aluminum nitride pellets. Significant amounts of the surface portions are thereafter removed to thereby significantly increase the purity of the aluminum nitride pellets.

摘要： A translating software emulator designed for converting code from a legacy system to a target system and fully preserving the synchronous exception state while still allowing for full and aggressive optimization in the translation. A user application is translated to a target system using full optimization techniques. The translation may be done dynamically by an emulator emulating the legacy system on the target system, or the translation may be a static translation or a compilation, fully generating a new executable program operable on the target system. The invention recovers from the exception properly by restoring the target machine state to the machine state expected by the legacy system. This recovery is done by using an exception delivery mechanism to restore the machine state of the target system before executing the exception handling code. The restoration of the machine state is done by executing a recovery block generated by the translation that modifies the machine state to match the legacy machine state.
