Book Description
Concentrating on the natural science aspects of forensics, top international authors from renowned universities, institutes, and laboratories impart the latest information from the field. In doing so they provide the background needed to understand the state of the art in forensic science with a focus on biological, chemical, biochemical, and physical methods. The broad subject coverage includes spectroscopic analysis techniques in various wavelength regimes, gas chromatography, mass spectrometry, electrochemical detection approaches, and imaging techniques, as well as advanced biochemical, DNA-based identification methods. The result is a unique collection of hard-to-get data that is otherwise only found scattered throughout the literature.

Book Description
In criminal investigations, latent fingerprints are often considered as reliable means of identifying suspects. However, the evidential value of a print is strongly dependent on the knowledge of its age (the time which has passed since deposition). Suspects might admit their previous presence at a crime scene, but often claim to have been there prior to or after the crime. Especially in regard to public or highly-frequented crime scenes, prints might lose their evidential value in this case, potentially leading to dropped charges. Despite its high relevance, the challenge of estimating a latent print's age could not be adequately addressed for 80 years. In this thesis, non-invasive high-resolution capturing devices are for the first time applied to the age estimation challenge, replacing classical physical or chemical print development techniques. They allow to capture a single print in regular time intervals and to systematically study its degradation behavior. Introducing automated processing methods in the form of a digital pipeline including preprocessing, feature extraction and age estimation techniques, objective age estimates are presented for the first time in this field. Maximum classification performances of different capturing devices between 76% and 86% are achieved for two-class problems. Furthermore, a qualitative influence model on the aging speed of latent prints is designed, forming a prerequisite for future studies.

Book Description
These proceedings comprise invited papers from highly experienced researchers in THz technology and security applications. THz detection of explosives represents one of the most appealing technologies to have recently emerged in dealing with terrorist attacks encountered by civil security and military forces throughout the world. Discussed are the most advanced technologies and developments, the various points of operational strength and weaknesses as well as are suggestions and predictions the best technological solutions to overcome current operational limits. The current status of various levels of cooling in THz detectors, sources and associated electronics are also addressed. The goal was to provide a clear view on the current technologies available and the required advances needed in order to achieve more efficient systems. This goal was outlined in part by establishing the baseline of current uncertainty estimations in physics-based modelling and the identification of key areas which require additional research and development.
