Learning of model discrepancy for structural dynamics applications using Bayesian history matching
Authors: Gardner P , Rogers T J , Lord C , Barthorpe R J 
Published: July 2019

AbstractCalibration of computer models for structural dynamics is often an important task in creating valid predictions that match observational data. However, calibration alone will lead to biased estimates of system parameters when a mechanism for model discrepancy is not included. The definition of model discrepancy is the mismatch between observational data and the model when the ‘true’ parameters are known. This will occur due to the absence and/or simplification of certain physics in the computer model. Bayesian History Matching (BHM) is a ‘likelihood-free’ method for obtaining calibrated outputs whilst accounting for model discrepancies, typically via an additional variance term. The approach assesses the input space, using an emulator of the complex computer model, and identifies parameter sets that could have plausibly generated the target outputs. In this paper a more informative methodology is outlined where the functional form of the model discrepancy is inferred, improving predictive performance. The algorithm is applied to a case study for a representative five storey building structure with the objective of calibrating outputs of a finite element (FE) model. The results are discussed with appropriate validation metrics that consider the complete distribution.

Abstract
This paper presents an evaluation of the global and regional consequences of climate change for heat extremes, water resources, river and coastal flooding, droughts, agriculture and energy use. It presents change in hazard and resource base under different rates of climate change (representative concentration pathways (RCP)), and socio-economic impacts are estimated for each combination of RCP and shared socioeconomic pathway. Uncertainty in the regional pattern of climate change is characterised by CMIP5 climate model projections. The analysis adopts a novel approach using relationships between level of warming and impact to rapidly estimate impacts under any climate forcing. The projections provided here can be used to inform assessments of the implications of climate change. At the global scale all the consequences of climate change considered here are adverse, with large increases under the highest rates of warming. Under the highest forcing the global average annual chance of a major heatwave increases from 5% now to 97% in 2100, the average proportion of time in drought increases from 7% to 27%, and the average chance of the current 50 year flood increases from 2% to 7%. The socio-economic impacts of these climate changes are determined by socio-economic scenario. There is variability in impact across regions, reflecting variability in projected changes in precipitation and temperature. The range in the estimated impacts can be large, due to uncertainty in future emissions and future socio-economic conditions and scientific uncertainty in how climate changes in response to future emissions. For the temperature-based indicators, the largest source of scientific uncertainty is in the estimated magnitude of equilibrium climate sensitivity, but for the indicators determined by precipitation the largest source is in the estimated spatial and seasonal pattern of changes in precipitation. By 2100, the range across socio-economic scenario is often greater than the range across the forcing levels.

Problems and perspectives of using warm waters of the state district power station in solving the provision of the population with fish
Authors: Govorkova L K , Kalayda M L 
Published: July 2019

Abstract
One of the sources of increasing fish production in Russia is intensive fisheries development of cooling reservoirs of thermal power plants and nuclear power plants. Cooling reservoirs have a unique temperature regime, which differs from natural water bodies by a higher temperature throughout the year. The increased water temperature causes changes in the quantitative and qualitative composition of the forage reserve, the ichthyofauna, the habitat of the hydrobiont and creates favorable opportunities for the introduction of a complex of thermophilic fishes and enhance the fish productivity of water bodies. The rise in water temperature also accelerates chemical and biochemical processes, promotes the intensive decomposition of organic substances, influences the gas regime of the reservoir, as a result, there may be overseas phenomena and the death of fish in cooling reservoirs. Therefore, the growing of aquaculture objects, the most resistant to high temperatures and temperature and gas changes, is becoming topical.

Mathematical modeling of surfactant self-organization in water solution in the presence of carbon nanotubes
Authors: Zueva O S , Rukhlov V S , Gazeeva E V , Mongush Y K 
Published: July 2019

Abstract
Based on the experimental results mathematical modeling of surfactant molecules organization in aqueous solutions into nanostructured formations was performed. The effect of the addition of carbon nanotubes on the processes was investigated. Numerical calculations of CTAB micelles dimensionless electrostatic potential were carried out in the framework of two most commonly used approximations: the Poisson-Boltzmann model and the jellium-approximation model for various surfactant concentrations in the presence and without of carbon nanotubes. A calculation procedure was developed that made it possible to determine the region of the most active counterions redistribution. The possibility of the interaction between micelles was noted, as a result of which a common self-consistent electric field appears, leading to spatial ordering in the bulk of solution. It was shown that there is a more rapid decay of the potential for the case of CTAB micelles in the presence of carbon nanotubes, which may indicate a change in the micelles morphology and their transition to a more compact form. It has been suggested that because increasing in the local surfactant concentration is observed near the carbon surface, carbon nanotubes can act as stimulators for the formation and growth of supramolecular structural complexes.

Published: July 2019

Abstract
By integrating justice theory and relational governance, this study aims to extend the existing research on PPP projects by finding the effects of distributive, procedural and interactional justice on cooperative behavior from the private sectors’ perspective. Through a thorough literature review, a concept model including justice perceptions and cooperative behavior is developed. With the help of 163 valid data samples from an online structured questionnaire survey, SEM is used to examine the model proposed. The study finds: (1) when interactional justice is higher, the private sector will perceive higher distributive justice and procedural justice and these two dimensions of justice perceptions act a mediating role in interactional justice and cooperative behavior; (2) distributive, procedural and interactional justice are actively related to the cooperative behavior, and the total impact of procedural justice is the greatest, and the smallest is interactional justice. This study enriches the theory of relationship governance and makes new contributions to the governance of PPP projects. And PPP project management practices can be given.

Abstract
The investigation dataset on Plumbum (Pb) in surface waters in Jiaozhou Bay in May and August 1990 studied the migration paths of Pb from source to ocean. The results unveiled that the major sources were port wharf, river flow, atmosphere deposition and marine current, whose source strengths were 13.39 μg L−1, 12.97 μg L−1, 11.01 μg L−1 and 10.82 μg L−1, respectively. This paper revealed that there were three different migration paths which were described by a block diagram model. Finally, the migration laws of Pb from sources to ocean were defined that the loss of Pb contents were increasing along with the increasing of migration path. Ocean was the sink of Pb. During the migration path from source to sink, a part of Pb was storing in water body, while another part was settling and fixing in sea bottom.
