Many biomedical data are in the form of time series. Analyses of these data include: (1) search for any biorhythm; (2) test of homogeneity of several time series; (3) assessment of stationarity; (4) test of normality of the time series histogram; (5) evaluation of dependence between data points. In this paper we present a subroutine package called TSAN. It(More)
We propose a hybrid power model for estimating the power dissipation of a design at the RT-level. This new model combines the advantages of both RT-level and gate-level approaches. We investigate the relationship between steady-state transition power and overall power dissipation. We observe that, statistically, two input sequences causing similar amount of(More)
Multiple input multiple output (MIMO) and orthogonal frequency division multiplexing (OFDM) are very promising techniques for broadband wireless communication. However, these promising techniques have not been realized in ad hoc networks. In this paper, we propose transceiver architecture with MIMO-OFDM and medium access control (MAC) scheme for broadband(More)
1 In this paper, we propose a hybrid approach for estimating the switching activities of the internal nodes in logic circuits. The new approach combines the advantages of the simulation-based t e chniques and the probability-based t e chniques. We use the user-specied control sequence for simulation and treat the weakly correlated data inputs using the(More)
Localization accuracy and energy efficiency are two important goals in sensor networks. In this paper, we propose a new medium access control (MAC) scheme to prioritize nodes with higher location estimation accuracy (location reliability) and higher residual energy level. The proposed solution is to encode the information of location reliability and(More)
In this paper we study the problem of distributing the set of crossings between two regions. A crossing is defined as the intersection of two nets. Three types of crossing-distribution problems are considered: (1) the quota problem, (2) the membership problem, and (3) the combination problem, which is a combination of the quota and membership problems. Our(More)
~ introduction Introduction BEAR-FP is a macrocell-based layout system which builds on its predecessor, thle BEAR system [l]. It uses BEAR's dynamic and efficient data representation, which unifies tohological and geometrical information, and BEAR's routing system. BEAR-FP, however, has a new bloorplanning procedure with integrated global routing and(More)
