Precision measurements ofB[ψ(3686)→π+π−J/ψ]andB[J/ψ→l+l−]

Precision Electroweak Measurements

Recent electroweak precision measurements from ee and pp colliders are presented. Some emphasis is placed on the recent developments in the heavy flavor sector. The measurements are compared to predictions from the Standard Model of electroweak interactions. All results are found to be consistent with the Standard Model. The indirect constraint on the top quark mass from all measurements is in ...

High-precision measurements

Power converters in the accelerator context are often required to deliver a performance that is unusual in an industrial context. This paper deals with some of the important aspects of high-precision output voltage and current control and in particular the current measurement transducers and their application.

Accuracy and precision of measurements obtained from conventional cephalograms and CBCT scan in orthodontics linear diagnostic measurements

Background and Purpose:  Due to the important role of imaging in the diagnosis and treatment plan in orthodontics, CBCT (Cone Beam Computed Tomography) images because of their three-dimensional nature, can minimize the disadvantages of two-dimensional images such as magnification, distortion, or superimposition. The purpose of this study was to evaluate the accuracy of conventional cephalograms...

Fuzzy models for precision measurements

Engineering and scienti c measurement results of continuous quantities are not precise numbers but more or less non-precise. Therefore so-called non-precise numbers are necessary to describe measurement results. Non-precise numbers are special fuzzy subsets of the set of real numbers. For vector quantities so-called fuzzy vectors are the best up to date model for related measurements.
