This paper introduces the use of decimal sequences in a code division multiple access (CDMA) based watermarking system to hide information for authentication in black and white images. Matlab version 6.5 was used to implement the algorithms discussed in this paper. The advantage of using d-sequences over PN sequences is that one can choose from a variety of prime numbers which provides a more f...

The IEEE Standard 754-1985 for Binary Floating-Point Arithmetic [1] is being revised [2], and an important addition to the current text is the definition of decimal floating-point arithmetic [3]. This is aimed mainly to provide a robust, reliable framework for financial applications that are often subject to legal requirements concerning rounding and precision of the results in the areas of ban...

The heat-resistant Salmonella senftenberg 775W and two strains of Staphylococcus aureus were tested at temperatures up to 68.3 C (71.1 C for S. senftenberg) in four different media. From the survival data, decimal reduction times (D values) were calculated for each set of conditions, and decimal reduction time curves were constructed for each bacterial strain in each medium. Slopes of decimal r...

• DECIMAL or NUMERIC is the type of numbers represented as strings of decimal digits. This will have some upper bound on the length of representations that the system is willing to tolerate. Although internally DECIMALs are stored just like strings, they are interpreted as numbers. Therefore any leading zeros are removed. On the other hand, trailing zeros are preserved because they could indica...

Nowadays Quantum-dot Cellular Automata (QCA) is one of the new technologies in nanoscale which can be used future circuits. Most digital circuits are implemented with CMOS technology, but has some problems like power consumption and circuit size. So, for solving these a method presented. It clear that converters play crucial role world. due to aforementioned point, this paper, two code converte...
