In shallow water, loud surface ships can mask the weak signal of the underwater target. In this case, the localization of the target is difficult due to side-lobes of the interferers. By incorporating the prior knowledge of the uncertain parameters, we have proposed a robust localization method [Liu, et al. Robust source localization using predictable mode subspace in uncertain shallow ocean environment...
Scaling of future many-core chips is hindered by the challenge imposed by ever-escalating power consumption. At its worst, an increasing fraction of the chips will have to be shut down, as power supply is inadequate to simultaneously switch all the transistors. This so-called dark silicon problem brings up a critical issue regarding how to achieve the maximum performance within a given limited power...
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,...
This paper investigates the bandwidth- and latencyconstrained IP mapping problem that maps a given set of IP cores onto the tiles of a mesh-based Network-on-Chip (NoC) architecture to minimize the power consumption due to intercore communications. By examining various applications' communication characteristics shown in their communication trace graphs, two distinguishable connectivity templates are...
This article studies the sample sizes of two most commonly used control charts, the X?? chart and the CUSUM chart. It takes the sampling cost (including the variable and fixed components) into consideration and uses a quadratic loss function as a performance measure. It is interesting to find that if nX?? = 4 and nCUSUM = 1, the X?? chart often outperforms the CUSUM chart. Furthermore, the overall...
