This paper addresses the development of accurate and efficient behavioral models of digital IC ports from measured transient responses. The proposed approach is based on the estimation of parametric models from port voltage and current waveforms. The modeling process is described and applied to the modeling of output ports. Its feasibility is demonstrated by the identification of a real device ...

Computer system’s runtime information is an essential part of the digital evidence. Current digital forensic approaches mainly focus on memory and I/O data, while the runtime instructions from processes are often ignored. We present a novel approach on runtime instruction forensic analysis and have developed a forensic system which collects instruction flow and extracts digital evidence. The sy...

A new parallel I/O scheme is implemented in the hybrid particle-field MD simulation code called OCCAM. In the new implementation the numbers of input and output files are greatly reduced. Furthermore, the sizes of the input and output files are reduced as the new files are in binary format compared to ASCII files in the original code. The I/O performance is improved due to bulk data transfer in...

historical memory or collective memory, in studies on cultural history and history of ideas, is often neglected. it is sufficient, for example, look at the names and titles to learn of the common view of a nation. this is true about alexander’s image in our culture. in our culture and some others, alexander is a myth and sometimes a unique hero. shahnameh can demonstrate this historical memory ...

Logged virtual memory (LVM) provides a log of writes to one or more speciied regions of the virtual address space. Logging is useful for applications that require rollback and/or persistence such as parallel simulations and memory-mapped object-oriented databases. It can also be used for output, debugging and distributed consistency maintenance. This paper describes logged virtual memory as an ...
