Agricultural food production is projected to be 70% higher by 2050 than it today, with the world population rising more 9 billion, 34% now. The farmers have been forced produce same resources. This pressure means that optimizing productivity one of main objectives producers but also in a sustainable way. Not only does agriculture face decline production, has had limitations data collection, storing, securing, and sharing, climate change, increases input prices, traditional supply chain...

Software defect prediction (SDP) in the initial period of software development life cycle (SDLC) remains a critical and important assignment. SDP is essentially studied during few last decades as it leads to assure quality systems. The quick forecast defective or imperfect artifacts may serve team use existing assets competently more effectively provide extraordinary products given narrow time. Previously, several canvassers have industrialized models for utilizing machine learning (ML)...

Acute Myeloid Leukemia (AML) is a kind of fatal blood cancer with high death rate caused by abnormal cells’ rapid growth in the human body. The usual method to detect AML manual microscopic examination sample, which tedious and time‐consuming requires skilled medical operator for accurate detection. In this work, we proposed an AlexNet‐based classification model images compared its performance LeNet‐5‐based Precision, Recall, Accuracy, Quadratic Loss. experiments are conducted on dataset...

Over the last two decades, social media platforms have grown dramatically. Twitter and Facebook are most popular platforms, with millions of active users posting billions messages daily. These allow to freedom expression. However, some exploit this facility by disseminating hate speeches. Manual detection censorship such speeches impractical; thus, an automatic mechanism is required detect counter in a real-time environment. Most research speech has been carried out English language. Still,...

In the recent era, a liver syndrome that causes any damage in life capacity is exceptionally normal everywhere throughout world. It has been found disease exposed more young people as comparison with other aged people. At point when ends up, endures just up to 1 or 2 days scarcely, and it very hard predict such illness early stage. Researchers are trying project model for prediction of utilizing various machine learning approaches. However, this study compares ten classifiers including A1DE,...

Abstract The shear strength of reinforced concrete members with or without reinforcement is influenced by the span to effective depth and longitudinal tensile ratios. In high-strength concrete, if paste has a higher than aggregates, then propagation cracks possible through aggregates rather around may fail brittle failure, which against most guideline’s philosophies. This paper investigates experimentally influence shear-span ratio ratios on behavior HSC beams having no reinforcement. A...
