The Domain Name System Security Extension (DNSSEC) leverages public-key cryptography to provide data integrity, source authentication, and denial of existence for DNS responses. To complement DNSSEC operations, DNSSEC Look-aside Validation (DLV) is designed for alternative off-path validation. Although DNS privacy attracts a lot of attention, the privacy implications of DLV are not fully invest...

Sulphur hexafluoride (SF6) is an inert and non-toxic gas with excellent properties for arc quenching and electrical insulation applications. The main drawback is its high greenhouse potential. In high voltage apparatuses it is used in sealed volumes e.g. in the interrupting chamber of a circuit breaker. Even so, through flanges and o-rings we encounter always a small amount of gas leakage. Ther...

Mobile devices are becoming increasingly popular. One reason for their popularity is the availability of a wide range of third-party applications, which enrich the environment and increase usability. There are however privacy concerns centered around these applications – users do not know what private data is leaked by the applications. Previous works to detect privacy leakages are either not a...

A substantial amount of treated water is lost every year due to leakages in distribution systems. Leakages can be identified and reduced using leakage detection methods, which broadly split into computer-based sensor-based methods. This systematic review focuses on trends methods published between 2000 2019, following the methodology proposed by PRISMA 2009 (Preferred Reporting Items for System...

The characteristics of transmitted acoustic field have important significance to the leakage detection and metasurface technology. When additional leak holes are present, conventional single neck Helmholtz resonator will naturally become one with multiple necks. Based on such a background, in this paper, effects leakages transmission properties Duct Resonator (DHR) device is investigated both a...

To date, the contribution of sea-based sources to global marine litter and plastic pollution problem remains poorly understood. Cruise ships produce large amounts wastewater concentrate their activities in fragile ecologically valuable areas. This paper explores for first time microplastics cruise ship wastewater, as well pathways from source sea. It thereto uses a novel approach identification...

Abstract The main idea of this article is to adopt the thesis that and, at same time, most effective (apart from proper maintenance and operation) element strategy limiting water losses in supply networks continuous integrated monitoring network using latest achievements IT technologies, including GIS (Geographical Information System), GPS (Global Positioning GSM (The Global System for Mobile C...
