Roger Scruton refers to Thomas Stearns Eliot in almost every one of his books, but despite the undoubtedly fundamental influence, which Eliot had exerted on the development of Scruton’s outlook, apart from a short article entitled Eliot and Conservatism, Scruton did not devote a separate work to Eliot’s thought. As I try to show this is due to the fact that Scruton was not so much a scholar of Eliot, as a continuator of his thought – not merely an expert on his philosophy and poetry, but an inheritor of his spiritual legacy. Both Eliot and Scruton belong to a current, which may rightly be called conservative philosophy of culture. In this paper I outline the conception of culture advanced by Eliot, and show how Scruton draws on this conception in his own spiritual development.

Encryption is one of the most effective methods of securing data confidentiality, whether stored on hard drives or transferred (e.g. by e-mail or phone call). In this paper a new state recovery attack with tabu search is introduced. Based on research and theoretical approximation it is shown that the internal state can be recovered after checking 252 internal states for RC4 and 2180 for VMPC.

The paper discusses the problem of video transmission in an IP network. The authors consider the ability of using the most popular video codecs that use both the MPEG2 Transport Stream and Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH). The main emphasis was given to ensuring the quality of service and quality assessment methods, taking into account not only the service- or network provider’s point of view but also the end user’s perspective. Two quality assessment approaches were presented, i.e. objective and subjective methods. The authors presented the results of the quality evaluation for H.264/MPEG-4, H.265/HEVC and VP9 codecs. The objective measurements, proved by statistical analysis of user opinion scores, confirmed the ability of using H.265 and VP9 codecs in both real time and streaming transmissions, while the quality of video streaming over HTTP with the H.264 codec proved inadequate. The authors also presented a connection between the dynamics of network bandwidth changing and MPEG-DASH mechanism operation and their influence on the quality experienced by users.

Glass is a material commonly used in construction. The development of technology related to it, and the increase in knowledge concerning its mechanical and strength properties offer opportunities for glass to be applied as a structural material. The advancement in glass structures, methods for their design, as well as guidelines and standards in this fields are being developed in parallel. This article describes the main assumptions contained in the German TRxV guidelines, the series of German DIN 18008 standards, and the European EN 16612, and EN 16613 standard. Moreover, the following article presents the concept of structural glass design included in the draft pre-standard prCEN/TS 19100, which provides the basis for the formulation of the European standard Eurocode 10. According to this pre-standard, structural elements of glass will be verified in four limit states, depending on the Limit State Scenario (LSS). Apart from the classic limit states, i.e., the ultimate limit state (ULS), and the serviceability limit state (SLS), it is also assumed to introduce a fracture limit state (FLS), and postfracture limit state (PFLS). The article also addresses the issue of laminated glass working in structural elements. Depending on the coupling between the glass panes and the polymer or ionomer interlayers, laminated glass can be divided into complete coupled or uncoupled, and can work in intermediate situations. The methods for determining the effective thickness contained in European standards and guidelines are discussed in this article.

Nodes' aware-mobility in the Internet of Things (IoTs) stills open defy for researchers, due to the dynamic changing of routing path and networks’ resource limitations. Therefore, in this study a new method is proposed called Mobility Aware - “Routing Protocol for Low power and Lossy Networks” (MARPL), that consists of two phases: in the first phase splitting the entire network into sub areas based on reference nodes with “Time Difference of Arrival” (TDoA) technique. While, the second phase, is about managing mobile nodes (MNs) in RPL according to the sub areas' ID. The Cooja simulator software has been used to implement and assess MA-RPL method performance, according to the data packet metrics (lost packet, packet delivery ratio PDR), latency and nodes' power usage in comparison with two methods: Corona (Co-RPL) and Mobility Enhanced (ME-RPL). The simulation results have been shown that the MA-RPL method consumes less nodes' energy usage, gives less latency with minimum data packet loss in comparison with Co-RPL and MERPL.
