Corrosion and wear has been a major challenge in most of our industries. CMT process has been selected as a weld technique because of its low heat inputs that makes it a promising technique for industrial application. However, the aim of this thesis is to study the competence of CMT welding process in cladding of mild stainless steel and performing a qualitative fault tree analysis. Furthermore, the ...

In recent years, there has been a shift in emphasis from critical infrastructure protection to that of resilience. This development reflects the acknowledgment that complete protection can never be guaranteed, and that achieving the desired level of protection is not cost-effective as a rule in relation to the actual threats. This article reviews the responses of four of the five Nordic countries ...

To meet the availability target and reduce system downtime, effective maintenance have a great importance. However, maintenance performance is greatly affected in complex ways by human factors. Hence, to have an effective maintenance operation, these factors needs to be assessed and quantified. To avoid the inadequacies of traditional human error assessment (HEA) approaches, the application of ...

In this thesis I address the challenges of Rio de Janeiro's ongoing public security reform, implemented through the establishment of the Pacifying Police Units (UPPs) in several of the city's favelas since 2009. I suggest that in order to address this problem, it is necessary to understand both the institutional and political context and conditions that the reform is set within, as well as the ...

Institutions are instructed to facilitate a holistic approach to the engineering profession, which integrates social science, technology, science ...

The number of good sites in less exposed locations for aquaculture farming is limited. Trends are now that the fish cages are increasing in both width and depth as well as more weather-exposed locations are taken into use. As the net cages continues to increase in size, so does the material costs. The design of the sea cages should be modified for safe and reliable use in remote offshore locations. ...

Wind chill factor is explained as the cooling sensation due to the exposure of wind temperature environment. The wind chill factor depends on air temperature, wind velocity, and humidity. Wind chill poses serious health risks. Various wind chill index models are given in the literature. In order to understand the wind chill effect, it is important to understand the phenomenon of heat transfer. There ...

Den teknologiske utviklingen innenfor mobiltelefonteknologien beveger seg stadig fremover, og i dag er det smarttelefonene som dominerer.
