Compilation for embedded processors can be either aggressive (time consuming cross-compilation) or just in time (embedded and usually dynamic). The heuristics used in dynamic compilation are highly constrained by limited resources, time and memory in particular. Recent results on the SSA form open promising directions for the design of new register allocation heuristics for embedded systems and...

BACKGROUND Breast conserving surgery followed by whole breast irradiation is widely accepted as standard of care for early breast cancer. Addition of a boost dose to the initial tumor area further reduces local recurrences. We investigated the dosimetric benefits of a simultaneously integrated boost (SIB) compared to a sequential boost to hypofractionate the boost volume, while maintaining norm...

For oil pipeline in mountain areas, high hydrostatic pressure the may cause error-opening of relief valves, and is discharged from to tanks, bringing spilling-over risk tanks. Therefore, simulating situations valves investigating discharge process are necessary for checking possibility accident then proposing measures improve system. This research focuses on a continuous undulating with large e...

In this paper, we propose the use of cyclic interval graphs as an alternative representation for register allocation. The \thickness" of the cyclic interval graph captures the notion of overlap between live ranges of variables relative to each particular point of time in the program execution. We demonstrate that cyclic interval graphs provide a feasible and e ective representation that accurat...

A register allocator must effectively deal with three issues: live range splitting, live range spilling, and register assignment. This paper presents a new coloring-based global register allocation algorithm that addresses all three issues in an integrated way: the algorithm starts with an interference graph for each region of the program, where a region can be a basic block, a loop nest, a sup...

Aerodigestive reflexes triggered by pharyngeal stimulation can protect the airways by clearing fluid from the pharynx. The objective of this study was to determine the relationship between the maximum capacity of fluid that can safely dwell in the hypopharynx [hypopharyngeal safe volume (HPSV)] before spilling into the larynx and the threshold volumes required to trigger pharyngoglottal closure...

In this paper, we analyze planar Particle Image Velocimetry (PIV) data of a laboratory hydraulic jump to investigate the large-scale coherence in the turbulent breaker shear layer. Two-point spatial correlations are used at various spatial locations to qualitatively assess the shape of the coherent structures in the different flow regimes. The structures are found to be stretched parallel to th...

An algorithm for integrating instruction scheduling and register allocation must support mechanisms for detecting excessive register and functional unit demands and applying reductions for lessening these demands. The excessive demands for functional units can be detected by identifying the instructions that can execute in parallel, and can be reduced by scheduling some of these instructions se...

One of the major problems traffic in big cities today is occurrence congestion phenomena on road network, which has several serious effects not only lives drivers, but also city inhabitants. In order to deal with these phenomena, it essential have an in-depth understanding processes that lead and its spilling over into contiguous areas city.
