Directional ionogram and F-region drift observations were conducted at seven digisonde stations in South America during the COPEX campaign from October to December 2002.Five stations in Brazil, one in Argentina, and one in Peru, monitored the ionosphere across the continent to study the onset and development of F-region density depletions that caus
This paper seeks to establish the significance of efficient evaluation of physical education programs in colleges and universities in the development of human personality, emotional health and fitness and the sociable demeanor of the learners.Nevertheless, the critical assessment methods present strong problems due to the inherent randomness and in
File fragment classification is an essential problem in digital forensics.Although several attempts had been made to solve this challenging problem, a general solution has not been found.In this work, we propose a hierarchical machine-learning-based Sweeper approach with optimized support vector machines (SVM) as the base classifiers for file fragm
Abstract Long non-coding RNAs (lncRNAs), such as SNHG6, have been identified as crucial regulators in the progression of various cancers, including esophageal squamous cell carcinoma (ESCC).Although the role of SNHG6 in ESCC is not completely understood, our findings demonstrated that SNHG6 expression is upregulated in ESCC tissues compared big boy
The production Sweeper of material with high precission and high complexity has been rapidly increasing in several industrial sector.The high accuracy is difficult to achieve during manufacturing due to vibration factors that influenced the final product of material.In this study the relationship between particle size and percentage of marble aggre
