Closed access Metadata (CSL-JSON)
DOI 10.1109/naecon46414.2019.9058290
Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Many researchers focus on using smart phone as toolbox, such as measuring height via barometer on smart phone. However, none of them compared the error rate that exists in different brands of mobile phones (e.g., Samsung, HUAWEI and iPhone). This paper carries out sets of control experiments to acquire plenty of data to analyze and contrast the error rate in those mobile systems. This paper uses elementary effects (EE) method to recognize variables that are non-influential. EE method is also used to sort affecting factors such as temperature and humidity, according to factors' significance. Furthermore, this paper minimizes the burst affecting variable random error by using a method called Filtering Burst Error and Random Error Process (FBEREP) to ensure the error rate. The validation is conducted using real smart phones. Based on the result, it can be observed that error rate is controlled within 2%.
