Parallel to the advancements in information and communication technologies, certain risks and security problems also arise, one of which is the authentication problem. In order to control who can have access to information sources, it is of utmost importance to develop an advanced authentication mechanism. It is through this mechanism that one can protect personal information, and prevent unauthorized access to the information or services provided. Likewise, this mechanism can block unauthorized persons to change or release information that is not public. All the work being undertaken in this field can be named as access control. The concept of authentication is among those concepts that have been studied for a long time in Turkey in the context of rapidly growing e-transformation efforts. In the process of e-transformation, the transformation circle is completed by first defining the concept of modeling business processes, followed by the formation of automation process, and lastly, providing services in electronic medium. 相似文献

Forensic paint comparisons are generally conducted on samples which, while small relative to their source, are still visible to the unaided eye and are thus located and analyzed without great difficulty. Here we demonstrate that a more detailed examination of candidate transfer surfaces can capture materials (questioned samples), even when such traces are invisible to the unaided eye. While certain analytical details (such as layer sequence or a pure FTIR spectrum) may not be obtainable from such traces due to their size and condition, a detailed analysis of the sample characteristics that are analytically accessible may still provide sufficient analytical data to arrive at a probative result. Here we present the application of this approach to a suspected paint transfer case, involving particles of paint as small as 40 μm in size. Using a combination of stereomicroscopy, polarized light microscopy, infrared microspectroscopy, Raman microspectroscopy, and SEM/EDS, all performed on a single, subsample of the original minute particle, it was possible to demonstrate evidence of a two‐way transfer between the suspected sources. Furthermore, the transferred paint particle in one direction could be classified as automotive in nature based on a combination of polymer composition, microscopic texture, and pigment package (which included three specifically identified pigments). This work demonstrates (i) the potential for improving detection limits when searching for a questioned sample, (ii) the potential benefits of higher resolution analyses on samples that would be traditionally labeled as “sample‐size limited,” and (iii) the value of case‐specific interpretation over standardized, one‐size fits all report templates. 相似文献

We model international negotiations on climate change. Leaders such as the European Union and the US can make proposals and influence veto players, including other countries and domestic lobbies, who must choose whether to accept or reject proposals. We explain why policy change has been minimal in this issue area, which veto-players receive the greatest and least attention and why leader actors wishing to see less progress are in such a strong bargaining position 相似文献

The NGRI Registry is a comprehensive census database collected by the Law and Psychiatry Division of the Department of Psychiatry at the Yale University School of Medicine. This longitudinal database was compiled following a systematic search of all available docket books from the superior courts and mental health records from the state hospitals in Connecticut beginning in January 1970. Detailed life span information is available for 364 insanity acquittees identified during the search. Comparative analyses with four other locales suggested that there were regional differences in diagnoses of and crimes committed by the acquittees. These initial analyses demonstrate the promise of this registry becoming one tool for collaborative research on issues relevant to law and mental health. 相似文献

Applications of Blue Light‐curing Acrylic Resin to Forensic Sample Preparation and Microtomy 下载免费PDF全文
This study discusses the results of an evaluation of a one‐part blue light‐curing acrylic resin for embedding trace evidence prior to the preparation of thin sections with a microtome. Through a comparison to several epoxy resins, the physical properties relevant to both trace evidence examination and analytical microscopy in general, including as viscosity, clarity, color, hardness, and cure speed, were explored. Finally, thin sections from paint samples embedded in this acrylic resin were evaluated to determine if, through smearing or impregnation, the resin contributed to the infrared spectra. The results of this study show that blue light‐curing acrylic resins provide the desired properties of an embedding medium, generate high‐quality thin sections, and can significantly simplify the preparation of paint chips, fibers and a multitude of other types of microscopic samples in the forensic trace evidence laboratory. 相似文献
