To facilitate effective targeted COVID-19 vaccination strategies, it is important to understand reasons for vaccine hesitancy where uptake low. Artificial intelligence (AI) techniques offer an opportunity real-time analysis of public attitudes, sentiments, and key discussion topics from sources soft-intelligence, including social media data. In this work, we explore the value leveraged using AI, as evidence source support health research. As a case study, deployed natural language processing...

Abstract The Systematic Review Toolbox aims provide a web‐based catalogue of tools that support various tasks within the systematic review and wider evidence synthesis process. Identifying publications surrounding specific is currently challenging, leading to high screening burden for few eligible records. We aimed develop search strategy could be regularly automatically run identify records SR Toolbox, thus reducing time on task those involved. undertook mapping exercise PubMed IDs papers...

Robotic gear deburring is a relatively difficult task because traditional position/force control laws are not suitable due to the complicated geometry and inevitable system positioning error. A algorithm based on force measurement investigated for unknown profile detection tracking, its further application process. PID type fuzzy logic controller applied deal with non-linear contact problem, velocity compensated position method utilized obtain faster response. Experimental results provided...

Introduction Various strategies to suppress the Coronavirus have been adopted by governments across world; one such strategy is diagnostic testing. The anxiety of testing on individuals difficult quantify. This analysis explores use soft intelligence from Twitter (USA, UK & India) in helping better understand this issue. Methods A total 650,000 tweets were collected between September and October 2020, using API hashtags as ‘#oxymeter’, ‘#oximeter’, ‘#antibodytest’,...
