BACKGROUND Modern smartphones allow measurement of heart rate (HR) by detecting pulsatile photoplethysmographic (PPG) signals with built-in cameras from the fingertips or the face, without physical contact, by extracting subtle beat-to-beat variations of skin color. OBJECTIVE The objective of our study was to evaluate the accuracy of HR measurements at rest and after exercise using a smartpho...

<span lang="IN">In the production process, quality checking is very important, one of which on wire. In process making brass-coated steel tire straps sometimes produce goods not in accordance with desired standard values. Checks that are carried out manually have low efficiency and quite high errors occur. So it necessary to check by measuring wavelength brass plated cord automatically. t...

In this paper, we present our developments of a novel approach for distributed memory Adaptive Mesh Refinement (AMR). Our approach is highly asynchronous and fully distributed that makes it suitable for extreme-level scaling. It takes negligible memory to store mesh structure as compared to the traditional approaches which are not scalable. It accomplishes adaptive mesh restructuring in just 1 ...

OBJECTIVE Colorectal cancer is one of the leading causes of cancer-related deaths in the world, although it can be effectively treated if detected early. Teleoperated flexible endoscopes are an emerging technology to ease patient apprehension about the procedure, and subsequently increase compliance. Essential to teleoperation is robust feedback reflecting the change in pose (i.e., position and...

The morphological and biochemical properties of plant canopies are strong predictors of photosynthetic capacity and nutrient cycling. Remote sensing research at the leaf and canopy scales has demonstrated the ability to characterize the biochemical status of vegetation canopies using reflectance spectroscopy, including at the leaf level and canopy level from air- and spaceborne imaging spectrom...

–The aim of this paper is to evaluate the quality of object oriented modules. In this work neural network approach is used along with PSO (particle swarm optimization) to find out fault prone components of software. The evaluation measures used are Accuracy, MAE (Mean absolute error), RMSE (Root mean square error) and the results are calculated on different iterations. The Accuracy, MAE, RMSE i...

Quadratic performance metrics such as root-mean-square error (RMSE) and time series correlation are often used to assess the accuracy of geophysical retrievals (satellite measurements) with respect to true fields. These metrics are related; nevertheless, each has advantages and disadvantages. In this study the authors explore the relation between the RMSE and correlation metrics in the presence...
