Interaction of light with gravitational waves

The physical properties of electromagnetic waves in the presence of a gravitational plane wave are analyzed. Formulas for the Stokes parameters describing the polarization of light are obtained in closed form. The particular case of a constant amplitude gravitational wave is worked out explicitly

Queering the Fop: Masculinity of James Rushworth in Austen’s Mansfield Park and Count Cassel in Inchbald’s Lover’s Vows

Jane Austen is an author who plays with gender roles in all of her novels. Mansfield Park is also not different. However, in Mansfield Park she takes up a play called Lover’s Vows by Elizabeth Inchbald and makes it a central focal point in this novel. What happens in this play similarly happens to the characters in the novel as well in not the same but a similar manner. Younger characters in Austen’s novel decides to stage Lover’s Vows after lengthy discussions. When they distribute the characters among them, similarities between the characters in the plays and in the novel start to appear too. In Inchbald’s play, there is a fop character named Count Cassel. James Rushworth decides to take up this role in the play becoming the fop in Jane Austen’s Mansfield Park. According to Melikoglu, the fop character was used in theatre to “show that the notion of the born gentleman and his inherent prerogative is ultimately not tenable” (Melikoglu). This effect is achieved through mocking the masculinity of the fop character which is seen both in Inchbald’s play and Austen’s novel respectively.The intention of this paper is to examine James Rushworth in Jane Austen’s Mansfield Park and Count Cassel in Elizabeth Inchbald’s Lover’s Vows as fop characters. The role of masculinity in the eighteenth century and in the beginning of the nineteenth century will be discussed. We will also try to conceive how the notion of masculinity is reflected upon the fop characters in the play and in the novel mentioned above. It will be seen that by mocking the fop characters Count Cassel and James Rushworth, the norms of masculinity at the time were supported by the literary works as well. The analysis will be made with the Queer Theory. Keywords: literature, gender DOI: 10.7176/JLLL/52-0

On the Barnes double gamma function

We aim to achieve the following three goals. First of all, we collect all known definitions, transformation properties and functional identities of Barnes double gamma function $G(z;\tau)$. Second, we derive an algorithm for numerically computing the double gamma function and present its complete asymptotic expansion as $z\to \infty$. Third, we derive some new properties, including a new product identity and new representations of the gamma modular forms $C(\tau)$ and $D(\tau)$.Comment: 23 pages, 2 figures. In this version we added Remark 1 on page 1

Automated Safety Analysis of Administrative Temporal Role-Based Access Control (ATRBAC) Policies using Mohawk+T

Safety analysis is recognized as a fundamental problem in access control. It has been studied for various access control schemes in the literature. Recent work has proposed an administrative model for Temporal Role-Based Access Control (TRBAC) policies called Administrative TRBAC (ATRBAC). We address ATRBAC-safety. We first identify that the problem is PSPACE-complete. This is a much tighter identification of the computational complexity of the problem than prior work, which shows only that the problem is decidable. With this result as the basis, we propose an approach that leverages an existing open-source software tool called Mohawk to address ATRBAC-safety. Our approach is to efficiently reduce ATRBAC-safety to ARBAC-safety, and then use Mohawk. We have conducted a thorough empirical assessment. In the course of our assessment, we came up with a "reduction toolkit," which allows us to reduce Mohawk+T input instances to instances that existing tools support. Our results suggest that there are some input classes for which Mohawk+T outperforms existing tools, and others for which existing tools outperform Mohawk+T. The source code for Mohawk+T is available for public download

Feasibility Study for Applicability of Ageing PSA Model Results in Risk-informed Decision Process

The aim of this case study was to demonstrate the benefits of using ageing probabilistic safety analysis (PSA) results in risk-informed decision process. First stage of the activities was aimed on the development of dataset which reflects age-dependent reliability behaviour for selected components using plant-specific, VVER specific and generic data. The second part describes the integration process of time-dependent reliability dataset in PSA model, quantification and comparison between aging (APSA) and base case PSA decision making results. Practical insights and conclusions are also presented. The report was prepared by the Nuclear & Radiation Safety Center (NRSC), Yerevan, Armenia, in cooperation with the Institute for Energy and Transport, EC Joint Research Centre, Petten, Netherlands, in the framework of the EC JRC Ageing PSA Network Task 8 activities.JRC.F.5-Nuclear Reactor Safety Assessmen
