In this paper, we present a new approach to linearizing zero-one quadratic minimization problem which has many applications in computer science and communications. Our algorithm is based on the observation that the quadratic term of zero-one variables has two equivalent piece-wise formulations, convex and concave cases. The convex piece-wise objective function and/or constraints play a great ro...

In this paper, a 10-bit digital Correlated Double Sampling (CDS) high-speed CMOS Image Sensor designed in 65nm BSI technology for a 1.1μm pixel is proposed. The readout architecture has been developed to read a 13Mpix sensor (4248 x 3216) at 55frames/s, requiring a row time of 5.5μs. The readout is based on a Piece-Wise Linear (PWL) ramp generator implementing an I/C structure. Two innovative c...

The paper deals with synthesis of sequential circuits defined by their algorithmic state machine notation. Such circuits have a number of specific properties which enable efficient design of the circuits by utilizing so-called linearization techniques. A typical linearization technique includes calculation of autocorrelation values for a system of logic functions corresponding to the circuit. F...

This paper concerns the application of reduced order modeling techniques to power grid simulation. Swing dynamics is a complex non-linear phenomenon due to which model order reduction of these problems is intricate. A multi point linearization based model reduction technique trajectory piece-wise linearization (TPWL) method is adopted to address the problem of approximating the nonlinear term i...

The paper deals with a numerical analusis for the seismic response of reinforced concrete structures containing cable elements. The cable behaviour is considered as nonconvex and nonmonotone one and is described by generalized subdifferential relations including loosening, elastoplastic fracturing etc. effects. The problem is treated incrementally by double discretization: in space by finite el...

Abstract. The paper is devoted to show that there are simple and accurate ways to compute a sigmoid nonlinearity in digital hardware by piece-wise linearization. This is done as the computations involved are complex, but even more interesting, for the data compression performed by the sigmoid, which can half the number of Boolean functions to be further implemented. We detail such an approximat...
