To study the effects of spudcan penetration on the adjacent foundations of offshore platforms, experiments and numerical simulations (using business software ABAQUS) are carried out. It is shown that the penetration of spudcan can cause the soil layer affected in an annular zone. The affected zone has a maximum width of one times the diameter of the spudcan. The deflection of the platform’s fou...

The introduction of distributed energy resources (DER) in radial parts of the grid, at low and mediumvoltage levels, may adversely impact the operation of the protection. Synchronous and induction generators contribute to the fault current, creating a second path next to the fault-current contribution from the grid. This may lead to fail-to-trip as well as incorrect trip of protection based on ...

The Mini-Mental State examination has been found to be a quick and valuable test for simple bedside screening, and for serial assessment of cognitive function in a population of 126 neurological patients. Amongst those with cognitive impairment, there was a close relation between the Mini-Mental State examination and the conventional Weschler Adult Intelligence Scale (WAIS). However, the Mini-M...

This paper summarizes recent measurements of the penetration depth and surface resistance of YBCO, with particular emphasis on the asymptotic behaviour at low temperatures and its dependence on hole doping and cation substitution. A complete set of measurements of the penetration depth tensor indicates that A(T) has a predominantly linear temperature dependence in both the a and b directions at...

Resting spores of Bacillus megaterium appear uniformly opaque and undifferentiated under the electron microscope. Germinated spores and spores which have lost their dipicolinic acid underwent characteristic changes in structure. Spores fixed with KMnO(4) lose their dipicolinic acid. Spores fixed with OsO(4) under certain conditions retain their dipicolinic acid. When conventional sectioning pro...

ZigBee Light Link (ZLL) is the low-power mesh network standard used by connected lighting systems, such as Philips Hue, Osram Lightify, and GE Link. These lighting systems are intended for residential use but also deployed in hotels, restaurants, and industrial buildings. In this paper, we investigate the current state of security in ZLL-based connected lighting systems. We extend the scope of ...

‘Universal access’ (UA) to the Internet and the associated information infrastructure has become an important economic and societal goal. However, UA initiatives tend to focus on issues such as physical access and geographical ubiquity, and measure adoption through penetration rates. In this paper, we apply an interpretive case study approach to analyze the Philadelphia wireless initiative to p...

Social Media Site (SMS) usage has grown rapidly in the last few years. This sudden increase in SMS usage creates an opportunity for data leakage which could compromise personal and/or professional life. In this work, we have reviewed traditional penetration testing process and discussed the failures of traditional penetration testing process to test the 'People' layer of Simple Enterprise Secur...

Penetration testing is the art of finding an open door. It is not a science as science depends on falsifiable hypotheses. The most penetration testing can hope for is to be the science of insecurity not the science of security inasmuch as penetration testing can at most prove insecurity by falsifying the hypothesis that any system, network, or application is secure. To be a science of security ...

Continental shelves are predominately ( 70%) covered with permeable, sandy sediments. While identified as critical sites for intense oxygen, carbon, and nutrient turnover, constituent exchange across permeable sediments remains poorly quantified. The central North Sea largely consists of permeable sediments and has been identified as increasingly at risk for developing hypoxia. Therefore, we in...
