This paper demonstrates the application of module arithmetic for controlling the level of information security by a new technique referred as integer splitting. The basic definitions and concepts of the method are provided. The mathematical function of arising transformation is described in detail; its properties were studied and the basic theorems were proven that justify the use of splitting in practical applications. An active system was designed and characteristic cases of its operation are considered.  相似文献

In the article we solve path planning task for an agent being multirotor unmanned aerial vehicle (multicopter). We propose an approach of estimating path geometry constraints based on UAV flight dynamics model and control constraints. Than we introduce a new path finding method which takes into consideration those geometry constraints and study this method both theoretically and empirically.  相似文献

ABSTRACT

This article answers the question “Are the sourcing practices in Finnish online journalism trustworthy?” Here, trustworthiness is operationalized as the fulfillment of audience expectations towards sourcing practices. To this end, expectations of young Finnish adults (aged 18–28) were compared to the observed practices of Finnish online journalists. A total of 36 news items (from 12 journalists working in three newsrooms, published in 2013 and 2017) were analyzed. The analysis indicates that online journalists’ sourcing practices largely do not conform to this audience segment's expectations. Namely, the audience expects more comprehensive investigation and thorough verification than what is common practice in online journalism. The use of high-credibility sources is both expected and commonplace. The results imply that transparency may be harmful rather than beneficial to journalism's credibility, as the unveiled practices do not always meet audience expectations.  相似文献

Until recently, little attention has been paid in the school classroom to creationism and almost none to intelligent design. However, creationism and possibly intelligent design appear to be on the increase and there are indications that there are more countries in which schools are becoming battle‐grounds over them. I begin by examining whether creationism and intelligent design are controversial issues, drawing on Robert Dearden's epistemic criterion of the controversial and more recent responses to and defences of this. I then examine whether the notion of ‘worldviews’ in the context of creationism is a useful one by considering the film March of the Penguins. I conclude that the ‘worldviews’ perspective on creationism is useful for two reasons: first it indicates the difficulty of using the criterion of reason to decide whether an issue is controversial or not; secondly, it suggests that standard ways of addressing the diversity of student views in a science classroom may be inadequate. I close by examining the implications of this view for teaching in science lessons and elsewhere, for example in religious education lessons and citizenship lessons and at primary level where subject divisions cannot be made in so clear‐cut a manner.  相似文献

Cosmopolitan education aims to transmit cosmopolitan forms of life in order to participate morally in the world community. The primary characteristics of this cosmopolitan education are its acceptance of the shared humanity of all persons as a fact of human existence and as a motivating guide for human interaction, and the requirement of democratic inclusion in deliberations of the governance of those interactions, including morality. Such an education in cosmopolitan morality requires means that befit its core components. This paper contrasts the concepts of strict and moderate cosmopolitanism, empirical and deliberative morality, and structural and dispositional cosmopolitanism to show that the moderate, inclusive and deliberative processes of deliberative dispositional cosmopolitanism are more suited to cosmopolitan education in morality than strong, empirical‐focused structural cosmopolitan efforts. Though strong, structural and empirically based forms may be more likely to guarantee preferred outcomes in the learning of specific morals or the implementation of institutional norms, they are also more likely to run afoul of the core components of cosmopolitanism because they will privilege outcomes over processes, and are thus more likely to be less inclusive and more coercive. In contrast, and even though they are less certain to guarantee preferred moral outcomes or actions, moderate, deliberative dispositional forms of cosmopolitan education embody the morality they seek to inform, and are more likely to find sustained internalised support over time.  相似文献
