In this paper we study the response to external disturbances of a double integrator with saturating feedback. For a class of disturbances that have bounded integrals over all intervals, we show that a linear static feedback law can always be designed to ensure boundedness of the states. Moreover, boundedness can be preserved if the disturbance is biased by a small DC signal. In the special case...

An SoC with ARM® CortexTM-M0 CPU cores and SRAMs is implemented in both 65nm baseline and Deeply Depleted ChannelTM (DDC) technologies. DDC technology demonstrates more than 50% active and static power reduction for the CPU cores at matched 350 MHz speed via VDD scaling and body biasing. Alternatively, DDC technology demonstrates 35% speed increase at matched power. The results hold across proc...

In a seminal paper Nagar (1959) obtained moment approximations for the k-class of estimators in a general static simultaneous equation model under the assumption that the structural disturbances were i.i.d and normally distributed. While it has been known for some time that the normality assumption can be relaxed when obtaining the bias approximation, it has not been demonstrated that the secon...

Motivated by the empirical findings concerning the importance of one’s current situation on her choice behavior, the main objective of this paper is to propose a rational choice theory that allows for the presence of a status quo bias, and that incorporates the standard choice theory as a special case. We follow a revealed preference approach, and obtain two nested models of rational choice tha...

A signal distorted by a system having a static, invertable, nonlinear characteristics can be exactly restored in the absence of noise. In this case the inverse of the characteristics can be used. When noise is superimposed to the distorted signal, the inverse characteristics may not be proper because the noise is strongly amplified. This noise has to be suppressed in the reconstructed signal, w...

Terahertz pulses are applied as an all-optical bias to ferroelectric thin-film BiFeO3 while monitoring the time-dependent ferroelectric polarization through its nonlinear optical response. Modulations in the intensity of the second harmonic light generated by the film correspond to on-off ratios of 220× gateable on femtosecond timescales. Polarization modulations comparable to the built-in stat...

Capacitive accelerometers [1] have advantages such as zero static bias current, the capability of high sensitivity, and excellent thermal stability, making their use in low-power applications attractive. In this paper, an interface ASIC designed for a capacitive 3-axis micro-accelerometer [2] is presented. The die area and power dissipation are reduced by using time-multiplexed sampling and dut...

In hierarchical models of gravitational clustering, virialized haloes are biased tracers of the matter distribution. As discussed by Mo & White (1996), this bias is nonlinear and stochastic. They developed a model which allows one to write down analytic expressions for the mean of the bias relation, in the initial Lagrangian, and the evolved, Eulerian, spaces. We provide analytic expressions fo...
