Intensity mapping of multiple emission lines is emerging as a new branch to astronomy, probe both properties ionizing sources and the medium between, in particular intergalactic medium. For Epoch Reionization (EoR) studies, multi-line experiments analysis methods are still their infancy. Here we explore optimal survey parameters for Ly$\alpha$ (and H$\alpha$) intensity up high redshifts reioniz...

Using a function algebra characterization of exponential time due to Monien 5], in the style of Bellantoni-Cook 2], we characterize exponential time functions of linear growth via a safe course-of-values recursion scheme.

This article is a critical review of some of the methods that have been used for the sampling, analysis, and monitoring of vapor-phase toluene diisocyanate (TDI). Only some of the methods that have received relatively widespread application have been addressed in this article. This review includes a "tutorial style" discussion of basic definitions and basic principles and procedures of quality ...

Assessment of exposure to airborne endotoxins has been studied for several years, especially in occupational environments, but a large number of procedures are used for sampling and analysis. This lack of standardization makes it very difficult to compare results and set internationally accepted threshold limit values (TLVs) or occupational exposure limits (OELs) for endotoxin exposure. This pa...

This paper proposes a novel L1 data cache design with dual-versioning SRAM cells (dvSRAM) for chip multi-processors that implement optimistic concurrency proposals. In this cache architecture, each dvSRAM cell has two cells, a main cell and a secondary cell, which keep two versions of the same logical data. These values can be accessed, modified, moved back and forth between the main and second...

Many methods for ranking fuzzy numbers have been proposed. The existing methods for ranking generalized fuzzy numbers based on the optimistic index (α) gives different values for comparing the numbers by using different values of the optimistic index (α) and it is the shortcoming of this method. So we introduce a new defuzzification using a crisp number for ordering and comparing the fuzzy numb...
