Modern networks-on-chip (NoC) systems are required to handle complex run-time traffic patterns and unprecedented applications. Data traffics of these applications are difficult to be fully comprehended at design-time so as to optimize the network design. However, it has been discovered that the majority data flows in a network are dominated by less than 10% of the specific pathways. In this paper,...
The problem of range sidelobe suppression is addressed for Stepped Frequency Continuous-wave (SFCW) radar. In this paper, a novel approach is presented via reiterative maximum signal minus interference level (RMSMIL) to suppress the range sidelobes. Results of simulations and real data show advantages of the proposed algorithm by comparing with the reiterative minimum mean-square error (RMMSE)-based...
Nonnegative matrix factorization (NMF) is a widely used method for blind spectral unmixing (SU), which aims at obtaining the endmembers and corresponding fractional abundances, knowing only the collected mixing spectral data. It is noted that the abundance may be sparse (i.e., the endmembers may be with sparse distributions) and sparse NMF tends to lead to a unique result, so it is intuitive and meaningful...
Urbanization has sprawled rapidly accompanying with transformation of the society, development of economy, increase of urban population and changes of landscape. The Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) has a unique capability to detect the nocturnal observation of artificial lighting which can reflect urbanization level. Most previous studies had focused...
We summarize recent progress on SRI's IraqCommtrade Iraqi Arabic-English two-way speech-to-speech translation system. In the past year we made substantial developments in our speech recognition and machine translation technology, leading to significant improvements in both accuracy and speed of the IraqComm system. On the 2008 NIST-evaluation dataset our twoway speech-to-text (S2T) system achieved...
Composable modeling enables the rapid, efficient and flexible assembly of simulation systems from components. To data there is a lack of formal descriptions for the process of composable modeling or composable modeling approaches are not operable in engineering. In view of the existing problems, a composable modeling approach based on Petri nets was proposed. Petri nets formal definition of component...
