A coder for television video signals working at a bit-rate of 1.15 Mbit/s is presented. It uses a special coding structure facilitating trick modes and a separated global and local motion compensation. Global motion is described by a central zoom and pan model. For the estimation of global motion a frame matching algorithm is explained. The advantages of using global motion parameters are given...

We explore how the internal use of non-GAAP performance metrics in compensation contracting relates to the disclosure of non-GAAP earnings to external stakeholders. Ex ante, it is unclear why information useful in contracting would be informative for valuation purposes unless a firm’s compensation and financial disclosure processes are related. We explore this relation using a large hand-collec...

It is known that Bitcoin enables achieving fairness in secure computation by imposing monetary penalties on adversarial parties. This functionality called with penalties. Bentov and Kumaresan (2014) [9] introduced the claim-or-refund can be implemented via Bitcoin. They achieved O(n) rounds broadcasts for any function, where n number of After that, [8] showed a constant-round protocol. Unfortun...

LuGre model has been widely used in dynamic friction modeling and compensation. However, there are some practical difficulties when applying it to systems experiencing large range of motion speeds such as, the linear motor drive system studied in the ∧ article. This article first details the digital implementation problems of the LuGre model based dynamic friction compensation. A modified model...

Social Incentives Matter: Evidence from an Online Real Effort Experiment Contributing to a social cause can be an important driver for workers in the public and nonprofit sector as well as in firms that engage in Corporate Social Responsibility activities. This paper compares the effectiveness of social incentives to financial incentives using an online real effort experiment. We find that soci...

A practical normal-mode helical antenna array together with a new method for the compensation of mutual coupling effect is proposed for the efficient adaptive nulling of interferences in a mobile communication environment. The helical antenna array is shown to be able to generate deeper nulls than an equivalent monopole antenna array in the presence of mutual coupling effect. The helical antenn...

This paper proposes a control algorithm for parallel active power filters, based on current-controlled pulsewidth-modulated converters, which allows precise compensation of selected harmonic currents produced by distorting loads. The approach is based on the measurement of line currents and performs the compensation of the selected harmonics using closed-loop synchronous frame controllers. Than...
