As a parameter important ballistic, the research about polygonal and grooved barrels’ behavior has not been widely carried out. The pressures, velocities, stresses, deformations, strains generated by firing of 9 mm × 19 ammunition in weapons with barrels are analyzed numerically experimentally, compared those pistols barrels. Finite Element Method equal boundary loading conditions was used both...

Stone-tipped weapons were a significant innovation for Middle Pleistocene hominins. Hafted hunting technology represents the development of new cognitive and social learning mechanisms within the genus Homo, and may have provided a foraging advantage over simpler forms of hunting technology, such as a sharpened wooden spear. However, the nature of this foraging advantage has not been confirmed....

There have been several anthropological studies on trauma analysis in recent literature, but few studies have focused on the differences between the three mechanisms of trauma (sharp force trauma, blunt force trauma and ballistics trauma). The hypothesis of this study is that blunt force and ballistics fracture patterns in the skull can be differentiated using concentric fractures. Two-hundred ...

Image Forensics has already achieved great results for the source camera identification task on images. Standard approaches for data coming from Social Network Platforms cannot be applied due to different processes involved (e.g., scaling, compression, etc.). Over 1 billion images are shared each day on the Internet and obtaining information about their history from the moment they were acquire...

Death investigations usually centre on the elucidation on the cause of death. This usually includes a full autopsy. Furthermore, ballistics and toxicology may be employed in some cases. Mostly, however, the cause of death can be found by macroscopical examination or histology in cases where no gross findings are in evidence at the time of autopsy. Examples are cases of poaching, traffic acciden...

Physiologic higher frequency phenomena ma.y be demonstrated in ballistocaidiograms from normal subjects. These phenomena consist of notches or multiple oscillations ontheH-I and K-L segments of the tracings. They may be demonstrated by recording the unfiltered output of an electromagnetic direct-body ballistocardiograph. They become more prominent as the transducer is applied closer to the sour...

Software and algorithm for calculating external ballistics the 'meeting task' with local objects, targets or lay is described, taking into account all factors optical-electronic shooting simulator 'Inhibitor' developed at Institute of mechanics UdmFRC UB RAS Computer facilities department Kalashnikov ISTU jointly JSC «Kalashnikov» Concern». To solve problem weapon ammunition an element a virtua...
