Hardware Implementation of a Configurable Motion Estimator for Adjusting the Video Coding Performances

2012

International audience; Despite the diversity of video compression standard, the motion estimation still remains a key process which is used in most of them. Moreover, the required coding performances (bit-rate, PSNR, image spatial resolution, etc.) depend obviously of the application, the environment and the network communication. The motion estimation can therefore be adapted to fit with these performances. Meanwhile, the real time encoding is required in many applications. In order to reach this goal, we propose in this paper a hardware implementation of the motion estimator which enables the integer motion search algorithms to be modified and the fractional search and variable block siz…

Fair Executive Compensation: Is Kalai-Smorodinsky More Just than Nash ?

2015

By considering Phelps' curve, the best disagreement point (BATNA) and the gains of negotiation, we examine what a fair distribution of executive wages should be. Beyond equality and Rawls' maximin, we focus on equality-of-gains (Nash) and on relative-equality-of-gains (Kalai-Smorodinsky). Equality-of-gains is close to maximin; executives may not accept to bargain. Relative-equality-of-gains allows executives and workers to obtain equal gains in percentage; executive compensation is not intolerably high to the price of a higher total payroll.

Tunable chirped fibre Bragg grating device controlled by variable magnetic fields

2002

A novel dynamic chirping fibre Bragg grating device based on a magnetic field applied to a magnetostrictive transducer capable of tuning its dispersion is presented. Chirping ranges up to 300 ps/nm have been demonstrated, which are suitable for several applications such as tunable transversal filtering and dynamic dispersion compensation.

Dynamics of real labour productivity and real compensation in Latvia

2019

Relationship between labour productivity and wages is an important issue not only for economists, but also for policy makers. In the last decades, we have witnessed that in the EU15 wage growth has been lagging productivity growth. At the same time in Latvia, also in some other central and eastern European member states, wages increased more than productivity, rising concerns about disbalance in the economy. However, comparison of wage level and productivity level in Latvia and respective levels in the EU15 shows that wage level in Latvia is much below the EU15 average value in absolute terms, but also in relation to productivity level. To understand whether dissimilarities in wage and prod…

How to Avoid Compensating CEO for Luck: The Case of Macroeconomic Fluctuations

2010

Incentive effects of performance-based compensation schemes for management may be weakened or biased by macroeconomic influences on remuneration. These influences can be seen as reflecting luck from the CEO’s perspective. In this chapter we present a model for how to avoid compensating CEO for luck by filtering out the macroeconomic influences. In the empirical section we analyze the impact of macroeconomic, industry and firm-specific factors on the compensations (salary, bonus, options, and pensions) of CEOs in 127 Swedish corporations during the period 2001-2007. We find macroeconomic influences on Swedish CEOs’ compensation to be substantial. Distinguishing between favorable and unfavora…

Dynamic stabilization of the magnetic field surrounding the neutron electric dipole moment spectrometer at the Paul Scherrer Institute

2014

The Surrounding Field Compensation (SFC) system described in this work is installed around the four-layer Mu-metal magnetic shield of the neutron electric dipole moment spectrometer located at the Paul Scherrer Institute. The SFC system reduces the DC component of the external magnetic field by a factor of about 20. Within a control volume of approximately 2.5m x 2.5m x 3m disturbances of the magnetic field are attenuated by factors of 5 to 50 at a bandwidth from $10^{-3}$ Hz up to 0.5 Hz, which corresponds to integration times longer than several hundreds of seconds and represent the important timescale for the nEDM measurement. These shielding factors apply to random environmental noise f…

High resolution Time of Flight determination based on reconfigurable logic devices for future PET/MR systems

2013

Abstract This contribution shows how to perform Time of Flight (TOF) measurements in PET systems using low-cost Field Programmable Gate Array (FPGA) devices with a resolution better of 100 ps. This is achieved with a proper management of the FPGA internal resources and with an extremely careful device calibration process including both temperature and voltage compensation. Preliminary results are reported.

Charge compensation by long-period reconstruction in strongly polar lithium niobate surfaces

2013

The microscopic structure of the polar (000$\overline{1}$) and (0001) surfaces of lithium niobate is investigated by atomic-resolution frequency modulation atomic force microscopy and first-principles calculations. It is found that the surface reconstructs at annealing temperatures sufficiently high to drive off external adsorbates. In particular a ($\sqrt{7}\ifmmode\times\else\texttimes\fi{}\sqrt{7}$)$R$19.1${}^{\ensuremath{\circ}}$ reconstruction is found for the (000$\overline{1}$) surface. Density-functional theory calculations show that---apart from the $(\sqrt{7}\ifmmode\times\else\texttimes\fi{}\sqrt{7})$---a series of adatom-induced surface reconstructions exist that lower the surfa…

Left-handed metamaterial coatings for subwavelength-resolution imaging

2012

We report on a procedure to improve the resolution of far-field imaging by using a neighboring high-index medium that is coated with a left-handed metamaterial. The resulting plot can also exhibit an enhanced transmission by considering proper conditions to retract backscattering. Based on negative refraction, geometrical aberrations are considered in detail since they may cause a great impact in this sort of diffraction-unlimited imaging by reducing its resolution power. We employ a standard aberration analysis to refine the asymmetric configuration of metamaterial superlenses. We demonstrate that low-order centrosymmetric aberrations can be fully corrected for a given object plane. For su…
