BACKGROUND Although the Netherlands currently has its own procedure for evaluating chemical compounds and setting occupational exposure limits (OELs), most of these limits were originally adopted in the 1970s from threshold limit values (TLVs) set by the American Conference of Governmental Industrial Hygienists (ACGIH). However, beginning in the late 1980s, criticism about non-scientific consid...

High throughput sequencing has become a powerful technique for genome analysis after this concept was raised in recent years. Currently, there is a huge demand from patients that have genetic diseases which cannot be satisfied due to the limitation of computation power. Though several softwares are developed using currently most efficient algorithm to deal with various types of sequencing probl...

The Internet, in particular the WorldWide Web , continues to expand at an amazing pace. We propose a new infrastructure, SuperWeb, to harness global resources, such as CPU cycles or disk storage, and make them available to every user on the Internet. SuperWeb has the potential for solving parallel supercomputing applications involving thousands of cooperating components on the Internet. However...

The Internet, best known by most users as the World-WideWeb, continues to expand at an amazing pace. We propose a new infrastructure to harness the combined resources, such as CPU cycles or disk storage, and make them available to everyone interested. This infrastructure has the potential for solving parallel supercomputing applications involving thousands of cooperating components. Our approac...

Space filling curves provide several advantages for indexing spatial data. We look at the Z-curve ordering and discuss three algorithms for navigating and querying k-dimensional Z-curves. In k-dimensional space, a single hyper-’Z’-shape in a recursive Z-curve forms a hypercube with 2k quadrants. The first algorithm concerns efficient checking whether a given quadrant of a local hyper-’Z’ inters...

The NetFPGA[2] community has made significant progress in making experimentation with high-speed reconfigurable networking hardware[6] easier and more accessible. They have provided an environment in which hardware modules implemented in Verilog can work together with software running on a host CPU using the primitives of DMA packet transfer and register access over the PCI bus. The NetFPGA’s V...

Medical Image registration is a preprocessing step for the medical images analysis which requires large computations when executed on sequential processors. To increase the execution speed, the registration process executed on the graphics processing unit which execute the registration process parallel. Registration process is divided into the parts in the form of kernels which are evaluated by...

This paper presents a method for optimizing register allocation for processors which can reconfigure their access to different register banks to increase the number of accessible registers. Register allocation like the graph coloring method of Chaitin aim at keeping a large number of values in registers and minimize the amount of necessary spill code. We extend that method in two directions: Fi...

Many architectures require that a program use pairs of adjacent registers to hold double-precision oating-point values. Register allocators based on Chaitin's graph-coloring technique have trouble with programs that contain both single-register values and values that require adjacent pairs of registers. In particular, Chaitin's algorithm often produces excessive spilling on such programs. This ...
