For those communities that can manage to muster the political will to act in the absence of “no more” moments, this chapter identifies the easy wins for building resilience. One crucial step is requiring companies to disclose climate risk, giving them a deeper understanding of what they are up against and what they might need to do to prepare. Another is using scenario analysis to test operations against different imagined futures. More generally, all investments, policies, plans, and programs should be routinely screened for climate resilience. At a minimum, to avoid wasting precious resources, any investments in long-lived infrastructure should both implement the lessons from past disasters and account for future climate-worsened calamities. Ultimately, the choices we make now—especially with regard to infrastructure and land use—can help us thrive even as climate change unleashes unfamiliar weather extremes on the planet.

The article is devoted to the development of the digital measuring and computing system for conducting stabilometric studies. The proposed system is based on an electromechanical stability platform. The block diagram of the developed system is presented. The selection of electronic components for the system is analyzed. The developed system is based on the ATmega328 microcontroller on the Arduino Uno R3 board. The HX711 board is used as an analog-to-digital converter. Strain gauges of 50 kg are used to measure the patients’ pressure forces. The overall design, technological, technical, and operational characteristics of the developed stabilometric platform are presented in the paper. The physical model of the developed system is shown. The operating algorithm is described, and the block diagram for calculation of the main stabilometric indicators (the length of the stabilogram, the modules and directions of the velocities, angular velocities, and dynamic stabilization factors) is presented. There are several examples demonstrating test operations of the developed system. Trial measurements and calculations have shown that the designed system fully meets the technical requirements for stabilometry equipment. The developed measuring and computing system allows registration and calculation of the spatial and temporal characteristics of patients’ motions.

Abstract Objectives The following report describes the development and implementation of a small-lab automation solution for small hospitals. Methods It uses a new generation of collaborative robots instead of the traditional laboratory automation lines with their input and output units and connected analyzers. After the Proof of Concept during fall 2018, both a centrifuge and several routine analyzers were integrated. Results The run-up phase ended after successful test operations in continuous mode in 2019. Routine operations were launched in October 2020 in a MVZ routine lab after a delay caused by the pandemic. Conclusions Apart from the direct cost savings for night duty or compensation for the lack of personnel, the mentioned solution delivers a significant upgrading of the laboratory technicians’ activities and an improvement in their working conditions.

The traditional fatigue life prediction methods based on the S-N curve all believe that the parameters in the model are deterministic constants and can be categorized to the deterministic life prediction. However, in practice, it is difficult to carry out a large number of experiments due to the limitation of time or the possible shortage of funds. In addition, the specimens used in the experiments are not exactly the same, and the test operations and data reading depend on the accuracy of the test equipment as well as the subjective judgment of the testers, which result to the uncertainty of the S-N curve. Therefore, the uncertainty should be considered in order to improve the accuracy of the fatigue life prediction. In this paper, the uncertain factors affecting the fatigue life of welded joints are summarized, and the generalized polynomial chaos (gPC) is introduced into fatigue life prediction. A novel probabilistic fatigue life prediction method combined with the nonlinear cumulative damage model considering the uncertainty of the S-N curve is constructed. An illustrative example is presented to demonstrate the advantages of the proposed approach.

<p>The availability of highly accurate Earth Orientation Parameters (EOPs) in near real time is of major importance for any type of positioning and navigation applications on Earth, Sea, Air and also in Space. This is equally true for all ESA missions and the EU space programs Galileo, EGNOS and Copernicus.</p><p>To ensure operational capability, ESA’s Navigation Support Office developed independent EOP products and services.</p><p>The EOPs are estimated based on a rigorous combination of the ESA’s contributions to the International Association of Geodesy (IAG) that are used as an input for the generation of the International Earth Rotation Service (IERS) products. For the ESA/ESOC EOP products, the individual parameters are combined on normal equation level and propagated with the contribution of model-based predicted Effective Angular Momentum (EAM) functions.</p><p>The ESA/ESOC’s EOP product generation is currently running in pre-operational mode.</p><p>This presentation will provide a high-level overview of the methodology and the status of ESA’s EOP products and services. In this context, the accuracy achieved in the test operations and the roadmap for the publication of ESA’s EOP products and services will be outlined.</p>

During ship block construction, watertight bulkheads weld of every cabin of ships need to undergo stress testing according to the tanks’ test plan. Every incomplete bulkhead cannot be sprayed in order to protect them after sandblasting; this seriously affects the process of construction. Therefore, the issue of this study is to maintain the integrity of the painting quality and reduce the destruction of the paint, ship-building personnel seek how best to complete the block operation. The aim of this project is to improve the recent watertight bulkheads fillet air test operations in the construction stage using TRIZ (theory of inventive problem solving), promote the ground painting session integrity of every ship, improve the tanks’ test plan in the dock, and reduce the time spent on dismantling operations and the painting operation. Through the TRIZ, this study proposed lots of improvements, some of which are: the watertight cabins can finish the tanks test plan completely, and the integrity of the ground painting can be promoted to reduce the range of cabin test in the dock and reduce watertight bulkheads’ dismantling time. Moreover, because of the considerate reduction of the destruction of the coating, the painting operation is of good quality. The results demonstrate that the TRIZ successfully controls the production quality during construction, reduces working time, and promotes full efficiency. This study saved more than US$1 million of the outsourcing fee.

The development of unconventional hydrocarbon resources in the Norman Wells region of the Central Mackenzie Valley, Northwest Territories, has been explored by the energy industry. In early 2014, Conoco-Philips Canada conducted two multi-stage test operations of hydraulic fracturing (HF) in the region. In this study, we combine seismic data from the Canadian National Seismograph Network, four new stations established by the Northwest Territories Geoscience Office in collaboration with Natural Resources Canada in the Norman Wells region, and a local dense array installed by Conoco-Philips Canada to study the seismicity distribution during the pre-HF, HF and post-HF periods. We have identified and located 130 earthquakes within 100 km of the geographic centre of the local seismic network near Norman Wells for the pre-HF period (11 September 2013 - 7 February 2014). In comparison, 231 events are located during the HF period (8 February 2014 - 10 March 2014), and for the two post-HF periods, 11 March 2014 - 31 July 2014 and 27 February 2015 - 31 December 2015, we have catalogued 255 and 138 events, respectively. Source parameters and detailed phase pickings of each earthquake are given in the Appendices.
