The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners. 相似文献

ABSTRACTThis article argues for the analysis of the flow of ideological discourse through society within and across three distinct but interrelated levels: (1) the canonically defined, or macro level, (2) the intermediate or meso level of competitive political appeals, political relevant public discourse and cultural criticism, and (3) the everyday or micro level of conceptual use by non-experts. This differentiation among levels of ideological action and influence helps us to clarify the objects and appropriate methods of ideological analysis. Methods applied in specific cases must facilitate an effective focus on phenomena on one of these levels while still allowing recognition of the complex forms of direct and indirect conceptual influence and connection between the levels. The article also serves as an introduction to the volume, giving a brief account of the analysis and argument of each contribution. 相似文献

The election of the first government of the Justice and Development Party (AKP) in 2002 was a turning point for Turkey. People wanted change. That's what the AKP offered. Their successful economic management has seen Turkey transformed over the last 12 years. Foreign policy initiatives also prospered and relations with a number of neighbours improved.. More recent events have led some commentators to ask whether Turkey is moving forwards or backwards on the democratic path. There are concerns that the Ataturk legacy of a secular state is being slowly eroded by the forces of a conservative democracy and that too much power is now concentrated in the hands of Mr Erdogan. This is the background to the 2013 riots in (westernised) Istanbul. And the situation in the region leaves little room for optimism. The challenge now is to promote the political stability and predictability that will encourage continuing foreign and domestic investment in Turkey and to undertake the further structural reforms essential if Turkey is to rise out of the middle income trap and climb into the group of wealthier nations. 相似文献

Existing accounts of British efforts to achieve a nuclear non-proliferation treaty between 1964 and 1968 largely overlook the later stages of decision making within the Labour government. Scrutiny of previously classified sources reveals that a desire for entry into the European Economic Community had a much larger influence on the content and conduct of British non-proliferation policy than previously suggested. By 1967, Prime Minister Harold Wilson sought a secondary role in treaty negotiations, and left the running to the superpowers. This avoided unnecessary conflict with the countries of the Community, resentful of the Treaty's discriminatory terms, and helped to protect Britain's application to join the EEC. Although this bid was unsuccessful, ambitions for future membership continued to influence non-proliferation policy in 1968. Indeed, a desire for future entry into the EEC helps to explain why Britain became the first nuclear weapon state to ratify the Treaty. 相似文献

Abstract A number of recent works have focused on the personal experiences of kamikaze pilots, but very little has been published in English on the Japanese government's effort to “kamikazefy” the civilian population in the final year of the Asian PacificWar (1937-45). To illustrate this effort, this article employs images taken from the author's personal collection of over 2,500 Japanese wartime publications (predominantly periodicals). In early 1945, the Japanese government announced a “fight to the death for the home islands,” in which civilian “home-front warriors” would fight alongside troops in the event of an Allied invasion. Civilian combatants were expected to follow the “no surrender” policy hammered into Japanese servicemen and to emulate the kamikaze pilots' spirit of supreme sacrifice. The article begins with a brief discussion of the ideology behind kamikazefication, inviting comparisons with suicide missions in other times and places. Historical context is further established by an overview of media accounts of Japanese suicide missions in the Asian PacificWar, beginning with the mission carried out at Pearl Harbor on 7 December 1941. An analysis of media reportage shows how members of suicide missions were glorified and made into role models for all Japanese, even women and children. Servicemen who died for their country were enshrined at the Yasukuni Shrine in Tokyo. The article concludes by suggesting reasons why civilians, even those who died fighting in the war, have not been similarly honored. 相似文献
