    Abstract: An ignition circuit and method, as may be used for igniting a gas discharge lamp, are provided. The circuit includes a voltage multiplier circuit connected to receive a signal corresponding to a DC bus voltage level from a rectifier circuit. The voltage multiplier circuit includes first and second voltage storing circuits configured to each respectively store a voltage level corresponding to a first multiple of the DC bus voltage level (e.g., at least twice the DC bus voltage level). The voltage multiplier circuit further includes a peak voltage holding circuit connected to the first and second voltage storing circuits to accumulate a voltage level corresponding to a second multiple of the DC bus voltage level (e.g., at least four times the DC bus voltage level). The circuit further includes an ignition module having a transformer selectively connected by way of a switch to the voltage multiplier circuit through a primary winding to receive the voltage accumulated at the peak voltage holding circuit, and thereby generate an ignition pulse voltage applied to the lamp through a secondary winding of the transformer.

    Abstract: A method and system for resource allocation. Specifically, in one embodiment, a method begins by receiving a request for an interactive session from a user. The request also comprises a resource requirement profile. Then, the method continues by selecting a computing resource having an affinity to the user. The computing resource is selected from a plurality of computing resources that are available to the user. The selected computing resource is implemented to support the interactive session. Thereafter, the selected computing resource is assigned to the user for use in the interactive session.

    Abstract: A method, apparatus, and computer program product for determining, in a computer environment, the equivalence, if any, of two algebraic expressions. The expressions are recast into a form of one or more token pairs arranged sequentially in a string, such that each token pair includes an operator followed by an operand. The strings are reduced in accordance with a set of predetermined simplifying rules. The reduced strings are compared by matching, to detect equivalence of the two algebraic expressions. The source code is compiled into object code, wherein the source code includes the two algebraic expressions, and wherein the compiling includes the recasting, the reducing, and the comparing. The method, apparal us, and computer program product may be used in compiler optimisation of source code and like computing tasks.
