With exponential development in the semiconductor technology in recent years, the magnitudes of test power consumption and test data volumes have increased significantly. This has resulted in over-testing because of IR drops. This paper proposes a reconfigurable scan architecture to overcome these challenges. The proposed architecture increases the flexibility of the scan partitioning technique...

Change points and changing regimes can be observed in many statistical time series. In this paper we analyze the most influential approaches of modeling these occurrences. Along with the theory some of the most interesting applications are presented. We find out that use of terminology is not unique, leading to considerable differences between the models, as will be pointed out.

Stability of periodic switched linear systems with fast switching patterns is studied by combining the method of averaging with exponential splitting. This approach yields less conservative bounds on stabilizing fast switching rates than can be obtained with prior approaches. Such bounds can be useful for analysis and design of switching control laws. The method is also generalized to arbitrary...

The switching-rate capability of mm-wave InGaAs PIN diodes of various sizes was evaluated for the first time by measuring their response times under various bias conditions. The dependencies of InGaAs PIN diode switching times are discussed, and the results are correlated with their DC characteristics. InGaAs PIN diodes demonstrated short switching times (fall time τF=250ps and rise time τR=130...

This paper gives sufficient conditions for a class of bang-bang extremals with multiple switches to be locally optimal in the strong topology. The conditions are the natural generalizations of the ones considered in [5, 14] and [16]. We require both the strict bang-bang Legendre condition, and the second order conditions for the finite dimensional problem obtained by moving the switching times ...

Due to the enormous improvement of networking technologies and the advances in media encoding and compression techniques, IPTV becomes one of the fastest growing services in the Internet. When offered via wireless technologies (e.g., WiMAX), IPTV can pave the way for quad-play in next generation networks and ubiquitous delivery. IPTV subscribers expect the same or even better Quality of Experie...

Here we propose and demonstrate an all-optical wavelength-routing approach which uses a tuning mechanism based upon the optical gradient force in a specially-designed nano-optomechanical system. The resulting mechanically-compliant “spiderweb” resonantor realizes seamless wavelength routing over a range of 3000 times the intrinsic channel width, with a tuning efficiency of 309 GHz/mW, a switchi...

We investigate a possibility to use composite magnetic tunnel junction structures (MTJs) to compose fast memory devices and efficient spin-torque nano-oscillators. In terms of magnetic memory, we study the switching statistics dependence on memory cell geometry by means of systematic micromagnetic simulations. We find that MTJs with a free layer composed of two ellipses with the axes a/2 > b in...
