The purpose of this study is to determine experimentally the effectiveness of passive drag reduction techniques (which involve adjusting surface geometry) within a chaotic multiphase flow system.To quantify read more the intrusion and disturbance caused, a liquid-air blast atomiser continuously discharges within a test section of air at atmospheric
Abstract Background Lagoons are common along coastlines worldwide and are important for biogeochemical element cycling, coastal biodiversity, coastal erosion protection and blue carbon sequestration.These ecosystems are frequently disturbed by weather, tides, and human activities.Here, we investigated a shallow lagoon in New England.The brackish ec
Abstract Background Achieving food security is a global priority and a concern for most African countries, including Ghana.Food systems providing varied and healthy diets without compromising the natural resource base, such as integrated crop–livestock diversification, are important for development planning and policy.Using cross-sectional data o
In this paper, a problem for Offline Signature Recognition and Verification is presented.Asystem is designed based on two neural networks classifier and three powerful features (global,texture and grid features).Our designed system consist of three stages: the first is preprocessingstage, second is feature extraction stage and the last is neural ne
