We describe and validate a feature-based system for calculation of likelihood ratios from 3D digital images fired cartridge cases. The includes database the bases 10 cartridges per firearm approximately 300 firearms same class (semi-automatic pistols that fire 9 mm diameter centre-fire Luger-type ammunition, have hemispherical firing pins parallel breech-face marks). were captured using Evofinder®, an imaging is commonly used by operational forensic laboratories. A key component research...

As one of the world's major crops, oats ( Avena sativa L.) require management strategies to increase their yield and quality.

Expert testimony is only admissible in common-law systems if it will potentially assist the trier of fact. In order for a forensic-voice-comparison expert's to fact, forensic voice comparison should be more accurate than fact's speaker identification. "Speaker identification courtroom contexts – Part I" addressed question whether by an individual lay listener (such as judge) would or less output system that based on state-of-the-art automatic-speaker-recognition technology. The present paper...

Expert testimony is only admissible in common law if it will potentially assist the trier of fact to make a decision that they would not be able unaided. The present paper addresses question whether speaker identification by an individual lay listener (such as judge) more or less accurate than output forensic-voice-comparison system based on state-of-the-art automatic-speaker-recognition technology. Listeners listen and probabilistic judgements pairs recordings reflecting conditions...

It is common in forensic anthropology to draw inferences (e.g., with respect biological sex of human remains) using statistical models applied anthropometric data. Commonly used can output posterior probabilities, but a threshold usually order obtain classification. In the forensic-anthropology literature, there some unease this "fall-off-the-cliff" approach. Proposals have been made exclude results that fall within "zone uncertainty", e.g., if probability for "male" greater than 0.95 then...

Recent research (Haworth 2018) has demonstrated how investigativeinterview data are (unintentionally) distorted as they pass through the criminaljustice system, and survey-based experiment we present here was designedto test our hypothesis that various aspects of processing police-suspectinterview may have an impact on quality official evidentialdocument produced. The quantitative qualitative findings from thisexperiment shed light on, provide a sound evidence base for this claim, ratherthan...

Facial asymmetry provides important information for detecting deception. The present study aims at deciphering deception in facial expression unique to Indian culture and detect differences between parameters of 'felt' emotion 'deceived' expression. expressions are analysed based on FacialAction Coding System.Results reveal that participants deamplify happiness whereas they neutralize mask negative emotions.

Accurate evaluation of an individuals' veracity is a fundamental aspect social functioning that allows individuals to act in adaptive ways. The domain deception detection ability still young, and many components this field are yet be touched which demands more research field.The present study aims at deciphering the structural composition face during felt, posed, deceived emotions facial expression unique Indian culture, using Facial Action Coding System (FACS). Quantitative analysis...

Bloodstain Pattern analysis particularly deals with the reconstruction of dynamic bloodletting events from static bloodstain patterns. patterns often help to sequence that might have occurred at a crime scene. It can also be used draw inference about position victim/s, perpetrator/s and bystander/s (if any) This paper is aimed intricate analysis/interpretation transfer stains produced by blunt ended objects By way experiments performed within laboratory setting this attempts establishing...

Swofford & Champod (2022) FSI Synergy article 100220 reports the results of semi-structured interviews that asked interviewees their views on probabilistic evaluation forensic evidence in general, and performed using computational algorithms particular. The interview protocol included a leading question based premise machine-learning methods used inference are not understandable even to those who develop methods. We contend this is false premise.

A novel multi-technique approach has been applied for the identification and mapping of wild orchids using a combination remote sensing spectral image analysis. The five orchid species identified were common spotted-orchid ( Dactylorhiza fuchsia ), heath maculata ) , pyramidal Anacamptis pyramidalis fragrant-orchid Gymnadenia borealis dark-red helleborine Epipactis atrorubens ). Field studies have done hand-held spectrometer operating in 400–700 nm visible spectrum, photogrammetry digital...

Disease prediction using computer-based methods is now an established area of research. The importance technological intervention necessary for the better management disease, as well to optimize use limited resources. Various AI-based disease have been documented in literature. Validated systems support diagnoses and decision making by doctors/medical practitioners. resource-efficient dissemination symptoms identified undertaken requirement present-day scenario paperless, yet seamless,...

The dataset developed consists of 108 blood drip stains with fresh porcine blood, admixed different dosage Warfarin and Heparin, respectively. For each particular type (i.e. at Heparin varied dosage) stain patterns were created by passive dripping from a 2.5 cm(3) subcutaneous syringe needle filled to capacity, 30°, 60° 90° angle impact corresponding fall height 20, 40 60 cm In the other 162 datapoints, 81 regular formed that had dripped passively without aforementioned height, while as...

Weapon transfer stains in a crime scene are often difficult to interpret. Given the large number of hammer hit events that take place each year, this work is largely aimed at analyzing different factors influence and distort regular stains. Different physical mechanisms under identical conditions formation distinct stain patterns. This basic highlight study. By experimentation, authors view quantity blood attached surface area hammer, exposed blood, dimensions angle inclination time fall,...

In "Speaker identification in courtroom contexts - Part I" individual listeners made speaker-identification judgements on pairs of recordings which reflected the conditions questioned-speaker and known-speaker a real case. The recording were poor, there was mismatch between condition condition. No contextual information that could potentially bias listeners' responses included experiment it decontextualized with respect to case circumstances other evidence be presented context Listeners'...

Like most other areas of Forensic Science, bloodstain pattern evidence interpretation is characterized by the overlap from various fields science such as physics, computer science, medical etc.For example, fluid mechanics particularly explains forces that lead to formation a particular pattern.Forensic Medical practitioners work towards drawing correlation between patterns formed and wound on body or head victim concerned.The paper studied hammer transfer stains in because easy availability...

Bloodstain Pattern evidence can be used for sequencing events at a crime scene.Again, it to trace the direction in which body was dragged.In addition also draw useful conclusions about relative position of victim/s, perpetrator/s and bystander/s (if any) scene.Stain patterns predicting probability that might have occurred scene.Bloodstain Patterns cannot particular associated with an individual.DNA analysis blood samples, serology test as associative uniquely identifying individual.This...
