We investigate the notion of distance on domains. In particular, we show that measurement is a fundamental concept underlying partial metrics by proving that a domain in its Scott topology is partially metrizable only if it admits a measurement. Conversely, the natural notion of a distance associated with a measurement not only yields meaningful partial metrics on domains of essential importanc...

In many applied programs in real-life problems, both physical inputs and outputsare heterogeneous which in this case the ecient cost and income modelcan not apply to evaluate the cost and income of related turnover. So, a measurementbased on the directional value of prot was presented which we havedeveloped it in this paper and have computed it for interval data. In fact, wehave measured the in...

recommender systems utilize information retrieval and machine learning techniques for filtering information and can predict whether a user would like an unseen item. user similarity measurement plays an important role in collaborative filtering based recommender systems. in order to improve accuracy of traditional user based collaborative filtering techniques under new user cold-start problem a...

Many experimental factors and uncontrollable factors may introduce errors in the distance measurement by continuous wave electron paramagnetic resonance. To deal with this problem, several C60 nitroxide diradical adducts with rigid structure and definite molecular dimension were used as distance calibration rulers. Based on the improvement of distance calculation program via adding simulation p...

introduction: the distance between the anterior commissure of the larynx and the first tracheal ring (ac.t. distance) is of great importance in laryngotracheal surgeries.  the amount of narrowing of the subglottic airway is used as a quantitative mean to determine whether the lesion is subglottic or has extended to the trachea and therefore helps in the prediction of the final prognosis.   mate...

Determination of Travel Distance for Noninvasive Measurement of Pulse Wave Velocity: Case Closed? To the Editor: Carotid-femoral pulse wave velocity (cfPWV) is currently considered the gold-standard measurement for arterial stiffness.1 In clinical routine, noninvasive assessment is the only feasible method, whereas, for research purposes, catheter-based invasive determination, as well as MRI, m...

The fast inspection of technical processes gains increasing importance. Time resolved distance and shape measurements of the dynamic deformation of high speed rotating objects are challenging. The measurement rate of conventional distance sensors is limited, since their uncertainty strongly increases with the surface velocity of the inspected object. In contrast, the recently developed laser Do...
