Monitoring software systems at runtime is key for understanding workloads, debugging, and self-adaptation. It typically involves collecting storing observable data, which can be analyzed online or offline. Despite the usefulness of system it may significantly impact execution by delaying response times competing with resources. The typical approach to cope this filter portions monitored sample ...

• Effects of particle shape and sample density on representative element volume (REV) for granular materials were investigated. The minimum REV reduces with increasing packing density. is sensitive to the characteristics measured. Analysis fluctuations around critical state stress ratio can be used determine REV. number contacts in samples indicates effect aspect Numerical studies particles or ...

The proposed approach aims to track multiple moving people in a colour video acquired with a single camera. The first phase of the approach consists in precisely detecting multi-human inside moving foregrounds. The input to this phase is foreground pixels which were extracted from the scene using any background subtraction technique. These moving foregrounds are then further segmented into mult...

finding a representative fluid in a hydrocarbon reservoir is crucial for integrated reservoir management. in this study, a systematic approach for screening and selecting consistent fluid samples in a reservoir was developed. the model integrated quality control (qc) of well conditioning before sampling, qc of pvt data, thermodynamic modeling and compositional gradient within a reservoir. well ...

Photoplethysmography (PPG) devices are widely used for monitoring cardiovascular function. However, these devices require skin contact, which restricts their use to at-rest short-term monitoring. Photoplethysmographic imaging (PPGI) has been recently proposed as a non-contact monitoring alternative by measuring blood pulse signals across a spatial region of interest. Existing systems operate in...

The Data Availability Statement appearing with the published article is incorrect. The correct Data Availability Statement should read: There are legal restrictions on the student outcome data. National Child Measurement Programme data was used as determined by the data sharing agreement with the then Information Centre of the National Health Service (NHS IC), now Health and Social Care Informa...
