Abstract Two case-studies on uncommon metals whiskers, performed at the Reliability Analysis Laboratory (RAL) of Northrop Grumman Innovation Systems, are presented. The components analyzed are an Oven Controlled Crystal Oscillator (OCXO) and an Electromechanical Relay. Investigative techniques were used to determine the chemical and physical makeup of the metal whiskers and develop an understanding of the underlying effects and mechanisms that caused the conditions conducive to whisker growth.

This essay will investigate a series of performances in Greece that showcase the theme of crisis discussed through the particular frame of their expanded scenographic strategies as dramaturgies of crisis. This expanded scenography is not restricted to politics and aesthetics of scenographic representation extending well beyond traditional staging paradigms to aspects that reinstate the emergence of social realities and a fundamentally social conception of space. Indicatively, this includes strategies like introducing various charged elements from lived experi-ence and contemporary visual culture, as well as conflictual aesthetics of the crisis and visual and spatial dramaturgies of the precarious. Sce-nographic dramaturgies of crisis seem to thrive on new spatial perfor-mance forms that directly interact with social realities and real spaces (like site-specific performance), while they mobilize a renewed address to found, shared public space putting to use strategies of participation. In this context of the crisis, the widespread multimedia idioms and the proliferation of video and cinematic idioms are also notable. Perfor-mances that thematize aspects of the crisis, such as Revolt Athens (2016), and the twin site-specific performances built with a core topographical address, Tea Time Europe (2014-15) and Eat Time Europe (2016) will be an-alyzed as key case studies to exemplify and further contextualize their scenographic approaches as content and context-oriented formulations, as visual and spatial dramaturgies that provide us with an entryway into performing crisis.

This article details a novel method for the determination of safe flight paths dynamically following an in-flight distress event. The method is based on probabilistic safety metrics which also include the touchdown and evacuation/rescue phases after landing. Two case studies simulating in-flight distress events, one from the west and the other from the east coast are presented using these formulations for a quantitative analysis. It is found that the nearest landing sites are not always the safest ones showing the benefits of the newly developed safety metrics. Finally, the path safety levels are plotted as a function of mission safety probability values using innovative polar plots that provide useful information to pilots.

System assessment is the part of the Water Safety Plan that evaluates whether a water supply system is capable of producing drinking water that meets the health-based targets. System assessment can be done at increasing level of detail, requiring more site specific information as the level of detail increases. Four case studies are presented with increasing level of detail, showing the type of information that is required for each of these levels and how each level informs risk management. The first case study shows how a system assessment can be performed without other site specific information than the type of source water and the type of treatment processes. The required data for the system assessment are collected from the large body of literature available. The second case study uses site specific microbial indicator data. The third study uses pathogen data and the fourth case study combines data on pathogens, microbial indicators and process parameters. The case studies show that the level of detail required largely depends on the risk management question.

Corrosion of reinforcement is considered as the major cause of most deteriorated concrete structures. As reinforcement corrodes, the load carrying capacity is affected and hence, the probability of failure increases. At the time of inspection of deteriorated structures, engineers are faced with the problem whether the available steel is enough to secure the safety of the structural member. This chapter addresses this problem based on reliability-based approach to evaluate the safety of the deteriorated members due to uniform corrosion under bending. A methodology is proposed to facilitate the determination of the member reliability index based on basic material properties and current loading. A step-by-step procedure is proposed based on charts developed in this study according to the Egyptian code provisions.
