This paper investigates the possibility of developing a nonintrusive, low-cost, flow-rate measurement technique. The technique is based on signal noise from an accelerometer attached to the surface of the pipe. The signal noise is defined as the standard deviation of the frequency-averaged time-series signal. Experimental results are presented that indicate a nearly quadratic relationship over the test region between the signal noise and flow rate in the pipe. It is also shown that the signal noise–flow rate relationship is dependent on the pipe material and diameter.
Aim: PREPARE-ABC is a pragmatic multicentre randomised controlled trial including an internal pilot designed to assess the clinical and cost-effectiveness of pre-and postoperative exercise in relation to short-and longer-term postoperative recovery outcomes in colorectal cancer patients undergoing surgical resection. Here, we report on internal pilot phase data for the first 200 patients randomised to the trial, which included prespecified stop-go criteria used to inform the decision to progress to the fully powered trial by the funder.Methods: Eligible and consenting patients are randomly assigned (1:1:1) to hospitalsupervised exercise, home-supported exercise or treatment as usual (TAU). Randomisation is concealed but clinical teams providing treatment and participants are unmasked.Primary outcomes are 30-day morbidity (Clavien-Dindo) and 12-month health-related quality of life (Medical Outcomes Study Health Questionnaire). Here, we present findings from the prespecified pilot phase which assessed feasibility of site set up, recruitment, adherence and acceptability of trial processes to patients and site staff.
Making Sense of War provides a comprehensive and clear analysis of the complex business of waging war. It gives readers a thorough understanding of the key concepts in strategic thought, concepts that have endured since the Athenian general Thucydides and the Chinese philosopher/warrior Sun Tzu first wrote about strategy some 2500 years ago. It also examines the influence on strategic choice and military strategy of political, legal and technological change. This book discusses strategy at every level of competition, employing a thematic approach and using historical examples from 500 BCE to the present. It discusses the contraints and opportunities facing military commanders in the 21st century, and demonstrates that the formulation of military strategy will continue to be perhaps the single most important responsibility for senior security officials. Making Sense of War offers original insights into the imperatives of military success in the era of asymmetric warfare.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
