GRB 991014 is one of the shortest gamma-ray bursts detected so far with the Wide Field Cameras aboard BeppoSAX, both in γ-rays and X-rays. The duration is 9.6 s in 228 keV and 3.2 s in 40 to 700 keV (as measured between the times when 5 and 95% of the burst photons have been accumulated). We refine the InterPlanetary Network annulus of the burst, present the detection of the X-ray afterglow of ...

The present work describes the development of XHINIA, a novel X-ray detection system able to be deployed both in production and in-service aeronautical environments. The system is based on a portable high-resolution X-ray detection system coupled to an automatic displacement tool. The evaluation of the detection system performances as well as the detection system detectability performances are ...

Over the past few months, exponential increase in COVID-19 cases has been overwhelming for many healthcare systems across world. With 114 million globally as of 28th February 2021, with India itself having 11.1 cases, it challenged us testing, quarantine, and safety measures. Having limited testing kits, not all patients that have symptoms respiratory illness can be tested using conventional te...

Abstract A simple and economic scintillator kit in combination with a computer-based oscilloscope was used to develop learning experience, comprised of set activities introduce students an interactive way the physics gamma-ray detection. The proposal for secondary school university is built by means frequent on-the-fly formative assessment collect difficulties ways overcome them. Internal decay...

Object recognition in X-ray images is an interesting application of machine vision that can help reduce the workload of human operators of X-ray scanners at security checkpoints. However, automatic inspection systems using machine vision techniques are not yet commonplace for generic threat detection in X-ray images. Moreover, this problem has not been well explored by machine vision community ...
