An aqueous extract of human placenta, which is used as wound healer, has been investigated in terms of fluorescence properties. When excited at 340 nm, it results in fluorescence emission having maxima around 436 nm, which is fairly specific for nicotinamide adenine dinucleotide, reduced form (NADH) and nicotinamide adenine dinucleotide phosphate, reduced(More)
The possibility of finger printing of multi component drugs, where a number of components are fluorescent, has been explored after generation of excitation-emission matrix (EEM) contour plots. With nicotinamide adenine dinucleotide, reduced form (NADH) and N-acetyl tryptophanamide (NATA) serving as reference compounds, the contour widths were found to be(More)
— The guard zone computation problem claims utmost importance in VLSI layout design, where the circuit components (or the functional units/modules or groups/blocks of different sub-circuits) that may be viewed as a set of polygonal regions on a two-dimensional plane, are not supposed to be placed much closer to each other in order to avoid electrical(More)
The counterfeit coin problem is well-known and truly interesting in Computer Science, Game theory, and also in Mathematics. In this problem the objective is to detect the fake coin(s) of identical appearance but different weight in minimum number of comparisons. The word counterfeit most frequently describes forgeries of currency or documents, but can also(More)
Digital Microfluidic Biochips (DMFB) is revolutionizing many areas of Microelectronics, Biochemistry, and Biomedical sciences. It is also known as 'Lab-on-a-Chip' for its popularity as an alternative for laboratory experiments. Pin count reduction and cross contamination avoidance are some of the core design issues for practical applications. Nowadays, due(More)
The guard zone computation problem finds immense applications in the field of VLSI physical design automation and design of embedded systems, where one of the major purposes is to find an optimized way to place a set of two-dimensional blocks on a chip floor. In VLSI layout design, the circuit components (or the functional units / modules or groups / blocks(More)
