    Abstract: A computer program product and computer system for implementing a method of compiler optimisation of source code during compilation of the source code in a computer environment. The compiler optimisation of source code includes: recasting two algebraic expressions into a form of one or more token pairs arranged sequentially in a string, each token pair including an operator followed by an operand; reducing the strings in accordance with a set of predetermined simplifying rules; and comparing the reduced strings by matching to detect an equivalence of the two algebraic expressions.

    Abstract: A power controller in a communication system adjusts the transmitted power level using adaptive prediction of channel fading for maintaining the power level for improved communications by using an adaptive nonlinear predictor that explicitly takes into account the propagation delay and channel fading where the transmitted power is determined on the basis of the measurement of the received power levels over the individual diversity branches for providing communication through a fading channel with effective performance equivalent to that of a channel without any signal fading.

    Abstract: A handheld computing device (10) having voice input and voice output includes a handheld unit (20) having a processor (11) and a display (18) communicating with the processor (11), a communication device (30) including means for voice input (43) and means for voice output (42), a mechanism (39, 41) for docking the communication device (30) with the handheld unit (20) forming a docked unit, the docked unit dimensioned to be held in one hand while being used for voice input and voice output, and at least one connection (23, 36) for carrying voice-representative signals between the handheld unit (20) and the device (30). Device (10) allows telephone-style, voice-driven, user-interface communications both when device (30) is docked with handheld unit (20), and when device (30) is detached from handheld unit (20). Communication device (30) is made lightweight so that it can be held for an extended amount of time during lengthy phone-style conversations, and may be equipped with a formed support such as a flexible loop (26) to let the user wear device (30) on one of user's ears for hands-free use. Device (10) can also be equipped with an image scanner to serve as a digital camera or videophone.

    Abstract: A scheduler for a grid computing system includes a node information repository and a node scheduler. The node information repository is operative at a node of the grid computing system. Moreover, the node information repository stores node information associated with resource utilization of the node. Continuing, the node scheduler is operative at the node. The node scheduler is configured to determine whether to accept jobs assigned to the node. Further, the node scheduler includes an input job queue for accepted jobs, wherein each accepted job is launched at a time determined by the node scheduler using the node information.
