In this paper we propose the synthesis of 4-(anthracen-10-yl)-1-cyclohexyl-3-phenoxyazetidin2-one. In addition to its synthesis AM1 calculations to characterize the physical properties of the molecule is also presented.

Construction industry reports by Latham [1994] and more recently Sir John Egan [1998], have highlighted the need for the construction industry to increase productivity, improve quality and reduce defects. In particular, the Egan report urged the industry to focus on construction processes as route to these improvements. However, the industry has not had a recognised framework or methodology to ...

    M. and M.   Abstract: Existence and uniqueness of solution for singular 2-D systems depends on regularity condition. Simple regularity implies regularity and under this assumption, the generalized wave model (GWM) is introduced to cast singular 2-D system of equations as a family of non-singular 1-D models with variable structure.These index dependent models, along with a set of boundary co...

In a modern computer, the CPU operates on values in its registers, and can fetch values from main memory, usually via several layers of caches. Large files are stored on disk, and data is transferred from disk to main memory. The memory closest to the CPU is fastest but smallest, and the memory farthest from the CPU is largest but has the highest latency. Moreover, the slower layers of memory h...

It is clear that the fastest memory levels are substantially smaller than the slowest ones. Generally, each level has a direct connection to the level immediately below it. (In addition, the faster, smaller levels are substantially more expensive to produce, so do not expect 1GB of register space any time soon.) Additionally, many of the levels communicate in blocks. For example, asking RAM to ...
