This research explores any potential for an on-chip cache compression which can reduce not only cache miss ratio but also miss penalty, if main memory is also managed in compressed form. However, decompression time causes a critical effect on the memory access time and variable-sized compressed blocks tend to increase the design complexity of the compressed(More)
A previously reported cytoplasmic male sterility-associated fragment was detected in chili pepper (Capsicum annuum L.) and sequenced in the mitochondria of a sterile plant. This fragment, 16 kb in size, contains two common mitochondrial genes, coxII and atp6-2, and the newly detected gene orf456, which appears to be a strong candidate gene for the male(More)
This article describes NuSCR, a formal software requirements specification method for digital plant protection system in nuclear power plants. NuSCR improves the readability and specifiability by providing graphical or tabular notations depending on the type of operations. NuSCR specifications can be formally analyzed for completeness, consistency, and(More)
Optical activity is the result of chiral molecules interacting differently with left versus right circularly polarized light. Because of this intrinsic link to molecular structure, the determination of optical activity through circular dichroism (CD) spectroscopy has long served as a routine method for obtaining structural information about chemical and(More)
A safety grade PLC is an industrial digital computer used to develop safety-critical systems such as RPS (Reactor Protection System) for nuclear power plants. The software loaded into a PLC is designed using specific PLC programming languages [1] such as FBD (Function Block Diagram) and LD (Ladder Diagram), which are then translated and compiled into a C(More)
