abstract main objective of this paper is to investigate the impact of exchange rate misalignment on wheat’s producer estimates (pse), using the 1989-2007 period’s data. for this purpose, vector error correction model (vecm) along with the use of real exchange rate based on purchasing power party (ppp) was applied to estimate nominal equilibrium exchange rates. then, by using market price suppor...

Myocardial perfusion studies suffer from artifacts caused by misalignment of the transmission and emission data due to the influences of voluntary and involuntary patient motion. Regardless of 68Ge or respiratory-averaged CT based attenuation correction and good patient cooperation, approximately 21% of perfusion studies exhibit artifacts arising from misalignment that cannot be corrected by ma...

In tracked ultrasound systems, temporal misalignment between image and tracker data results in incorrect image pose. We present a fully automatic temporal calibration. We image a flat plate in water with a tracked probe undergoing periodic uniaxial freehand translation. Using robust line detection scheme, we compute temporal misalignment as difference between probe and corresponding image posit...

For luminosity and proton-proton total cross section measurement, the standard LHC Physics optics has been modied for the ATLAS experiment in the so-called High Beta optics with β*=2625 m. The high beta optics takes into account the whole LHC ring. Protons are tracked from the interaction point to the detectors. Tolerances on the β* are given and the effect of misalignment errors is checked. W...

In order to measure reliable electron densities of fusion plasmas by using Thomson scattering system, both accurate absolute calibration and long-term stability in the system are required. Even if slight misalignment of some optics occurs, it may cause large errors in measured densities. We propose a new method to obtain correction factors to the errors originated from misalignment by using ste...

We have studied numerically the evolution and decay of axion strings. These global defects decay mainly by axion emission and thus contribute to the cosmological axion energy density. The relative importance of this source relative to misalignment production of axions depends on the spectrum. Radiation spectra for various string loop configurations are presented. They support the contention tha...

This paper studies misalignment of commitments associated with temporal constraints. We propose a diagnosis algorithm where agents reason based on the current states of their commitments. We also provide an alignment policy that can be applied by an agent when the diagnosis algorithm identifies a misalignment. We formalize a delivery process from e-commerce using REC, and present a case study t...

Color printing proceeds with multiple halftone separations overlay. Because of separation overlay misalignment in printing, the percentage of different primary color combination may vary and it will result in color shift. In traditional printing procedure with AM halftone, every separation has different screening angle to make the superposition pattern in a random style, which will reduce the c...
