Safety helmet wearing plays a major role in protecting the Vases safety of workers in industry and construction, so a real-time helmet wearing detection technology is very necessary.This paper proposes an improved YOLOv4 algorithm to achieve real-time and efficient safety helmet wearing detection.The improved YOLOv4 algorithm adopts a lightweight n

Abstract: The Godesberg programme (1959) is considered a major shift in European social democratic ideology.This article explores its genesis and offers a history of both the written text and its subsequent uses.It does so by shedding light on the organizational constraints and the personal strategies of the players involved in the production of th

The methodology for seismic performance evaluation of a residential building in Indonesia with the use of seismic isolation is considered.An 8-storey reinforced concrete frame residential building with shear wall structural system was selected as a case study.Nonlinear methods of seismic response analysis were used to calculate OREGANO-8 the respon

Measuring volume fractions and identifying the flow regime are important challenges in the oil industry.In the present study, three different flow regimes were Bike Parts - Tools simulated by MCNPX code.A 137Cs source and two NaI detectors have been used in order to count the transmitted photons.The counted data had high-frequency noises.In order t

Cereals are the most broadly produced crops and represent the primary source of food worldwide.Nitrogen (N) is a critical mineral nutrient for plant growth and high yield, and the quality of cereal crops greatly depends on Course a pied - Femme - Vetements - Chandail - Short sleeves a suitable N supply.In the last decades, a massive use of N fertil
