Thermal transfer printing refers to printing processes that utilize heat to produce an image by either physical or chemical means or by a combination of both. As the technology has improved and the supplies have become less expensive, the use of thermal printing in the personal and business markets has increased significantly. Specifically, dye diffusion thermal transfer and thermal mass transfer have become predominant in the production of counterfeit credit cards, drivers' licenses, and other types of documents produced on plastic media. Chemical analysis by means of thin layer chromatography (TLC) has proven to be useful in characterizing various types of inks (e.g., writing and inkjet inks). In this study, the authors examined 81 different samples that included a total of 54 printer samples (43 photographic prints on paper and eleven plastic card samples) and 27 printer ribbons. A new TLC method was developed and tested utilizing a solvent system (80% n-hexane, 3% methyl ethyl ketone, and 17% ethyl acetate) that is capable of producing excellent resolution. 相似文献

This study extends the current use of Bayesian networks by incorporating the effects of allelic dependencies in paternity calculations. The use of object-oriented networks greatly simplify the process of building and interpreting forensic identification models, allowing researchers to solve new, more complex problems. We explore two paternity examples: the most common scenario where DNA evidence is available from the alleged father, the mother and the child; a more complex case where DNA is not available from the alleged father, but is available from the alleged father’s brother. Object-oriented networks are built, using HUGIN, for each example which incorporate the effects of allelic dependence caused by evolutionary relatedness. 相似文献

In 2016 Her Majesty's Courts and Tribunals Service embarked on a significant modernisation programme with a view to developing online courts. In pursuit of this ambition the Courts and Tribunals (Online Procedure) Bill seeks to introduce new procedural rules to govern the online jurisdiction, giving the Lord Chancellor and an Online Procedure Rule Committee the power to mandate which proceedings will be conducted online and what assistance will be provided to users. In this study we analyse survey data and case decisions to highlight the importance of channel plurality and digital support in light of the shift to online courts. Our findings identify the groups most at risk of digital exclusion, and the expectations the judiciary sets in relation to internet access, capability, and the design of online systems. We conclude by detailing what our findings mean for safeguarding access to justice in the digital age. 相似文献
