  • Forensic complexity

    This note introduces forensic complexity as a multidisciplinary approach to the study of comprehension in complex situations in order to enable justifiable action. The term itself seems paradoxical when viewed as analysis of the unpredictable or irreducible. The paradox is resolved by the adoption of an internally consistent perspective for complex situations referred to as a complex situations ...

  • A Forensic Approach to Solve a Ground Water Contamination Problem

    In 2000, a subdivision outside a small city in southeast Texas discovered that the water supply wells that individual households had drilled were contaminated with trichloroethylene or TCE as it is commonly called. Since the extent of TCE contamination seemed to extend for over a mile in length, it was thought the “event” or “events” leading to the contamination had occurred some years ago. The ...

  • Case study - Oklahoma crude oil forensic analysis

    An oil company used Sitelab’s laboratory to perform oil forensic analysis testing crude oils from different well sites to determine the percentage of oil content from two formations. The wells tap into these zones at different depths, thousands of feet below the ground. Knowing what type of oil being pumped is important. All six oil samples had similar GRO content, but the PAH content in ...

  • Precellys application focus forensic - case study

    Forensic laboratories working with hard samples such as hair [1, 2J, bone [3], teeth, skin, etc. experience difficulties with DNA extraction due to the high energy needed to grind these tissues. Moreover, biological evidence is available in small quantities and the current techniques used do not provide high quality results. The Precellys homogenizers provides high speed sample disruption based ...

  • Forensic engineering investigations of disasters: going 'beyond the widget'

    Forensic engineering is the use of engineering knowledge and techniques to create evidence for the legal system. Both litigation and regulatory systems use engineering evidence in making legal decisions. Forensic engineering plays a key role in investigating disaster scenarios. But commentators have described the investigatory focus on trivial proximate causes as the 'Widget' approach, where the ...

  • Identification of forensic fabrics using a portable Raman spectrometer

    At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. While FTIR has been used for analysis in the past, the strong absorption of the fabric or the glass slide where it is mounted makes the spectrum very hard to interpret. In recent years, Raman spectroscopy has been studied extensively for ...

  • Forensic engineering of fire damaged concrete structures: state of the art

    All structures are likely to be subjected to elevated temperatures during an event of fire. Due to accidental thermal loads the structures may be subjected to cracking and that affect both the mechanical or structural properties. Even though total collapse of structure is rare, the structures or a part of it may suffer partial damage. Thus structures need to be thoroughly assessed in order to ...
