Collusive Compensation Schemes Aided by Algorithms [PDF]
SSRN Electronic Journal, 2021 Sophisticated collusive compensation schemes such as assigning future market shares or direct transfers are frequently observed in detected cartels. We show formally why these schemes are useful for dampening deviation incentives when colluding firms are temporary asymmetric.

Tight Interval Inclusions with Compensated Algorithms [PDF]
IEEE Transactions on Computers, 2020 Compensated algorithms consist in computing the rounding errors of individual operations and then adding them later on to the computed result. This makes it possible to increase the accuracy of the computed result efficiently. Computing the rounding error of an individual operation is possible through the use of a so-called error-free transformation .

Reversible Watermarking Algorithm with Distortion Compensation [PDF]
EURASIP Journal on Advances in Signal Processing, 2011 Abstract A novel reversible watermarking algorithm with two-stage data hiding strategy is presented in this paper. The core idea is two-stage data hiding (i.e., hiding data twice in a pixel of a cell), where the distortion after the first stage of embedding can be rarely removed, mostly reduced, or hardly increased after the second stage.

Numerical Stability of Lanczos Methods [PDF]
, 1999 The Lanczos algorithm for matrix tridiagonalisation suffers from strong numerical instability in finite precision arithmetic when applied to evaluate matrix eigenvalues. The mechanism by which this instability arises is well documented in the literature.

Compensated Evaluation of Tensor Product Surfaces in CAGD
Mathematics, 2020 In computer-aided geometric design, a polynomial surface is usually represented in Bézier form. The usual form of evaluating such a surface is by using an extension of the de Casteljau algorithm. Using error-free transformations, a compensated version of

Position estimation delays in signal injection-based sensorless PMSM drives [PDF]
, 2012 The causes of position estimation delays and their effects on the sensorless control of permanent magnet synchronous motor drives are investigated. The position of a permanent magnet synchronous machine is estimated via the injection of high frequency ...

New Fault-Location Algorithm for Series-Compensated Double-Circuit Transmission Line
IEEE Access, 2020 This paper proposes a new fault location algorithm to accurately locate the faults of series-compensated double-circuit transmission line and improve the stability of power system operation, which is not affected by fault types. The proposed algorithm is
