OBJECTIVES/HYPOTHESIS Otorhinolaryngology (ORL) is considered a specialty associated with few serious patient injuries. Research data that support this belief are, however, scarce. We analyzed claims associated with ORL to determine the number of Finnish cases and the possible common denominators. STUDY DESIGN Register study of ORL cases in the Patient Insurance Centre (PIC), the Regional Sta...

The compensated Horner algorithm and the Horner algorithm with double-double arithmetic improve the accuracy of polynomial evaluation in IEEE-754 floating point arithmetic. Both yield a polynomial evaluation as accurate as if it was computed with the classic Horner algorithm in twice the working precision. Both algorithms also share the same low-level computation of the floating point rounding ...

We propose a quad−tree scheme for obtaining sub−pixel estimates of interframe motion in the frequency domain. Our scheme is based on phase correlation and uses motion compensated prediction error to control the partition of a parent block to four children quadrants. This criterion guarantees a monotonic decrease of the motion compensated prediction error with an increasing number of iterations ...

Multi-hypothesis prediction extends motion compensation with one prediction signal to the linear superposition of several motion-compensated prediction signals. These motion-compensated prediction signals are referenced by motion vectors and picture reference parameters. This paper proposes a state-of-the-art video codec based on the ITU-T Recommendation H.263 that incorporates multi-hypothesis...

The aim of the research was studying of the character of changes of microcirculation condition at persons of middle age with the compensated and noncompensated diabetes mellitus type 2. 95 patients of middle age with compensated and 100 patients with noncompensated diabetes mellitus type 2 were surveyed. It has been established that all patients irrespective of compensation level of disease had...

Although most modern monolithic solid state operational amplifiers (op-amps) are internally compensated, externally compensated units provide an invaluable degree of freedom to analog designers. As a result, these op-amps offer true 'general purposeness,' since allowing the user to choose the amplifier's compensation can drastically improve performance in many applications. This thesis proposes...

Compensated summation algorithms are designed to improve the accuracy of ill-conditioned sums. They are based on algorithms, such as FastTwoSum, which are proved to provide, with rounding to nearest, the sum of two floating-point numbers and the associated rounding error. Discrete stochastic arithmetic enables one to estimate rounding error propagation in numerical codes. It requires a random r...

Standard results in general equilibrium theory, such as existence and the second efficiency and core equivalence theorems, are most easily proved for compensated equilibria. A new condition establishes that, even with individual non-convexities, in compensated equilibrium any agent with a cheaper feasible net trade is also in uncompensated equilibrium. Some generalizations of McKenzie’s irreduc...

The equalizer tap length requirement is investigated analytically and numerically for differential modal group delay (DMGD) compensated fiber link with weakly random mode coupling. Each span of the DMGD compensated link comprises multiple pairs of fibers which have opposite signs of DMGD. The result reveals that under weak random mode coupling, the required tap length of the equalizer is propor...
