Abstract:
... Fugitive road dust (FRD) contributes a great deal to urban rainwater and air pollution and is commonly controlled by water-sprinkling in most Chinese cities. However, there is a lack of information on its effectiveness. We used the Testing Re-entrained Aerosol Kinetic Emissions from Roads (TRAKER) method to monitor different types of roads in Baoding city before and within 1 hr after water-sprinkl ...
... Case studies form a vital part of sociological inquiry. Despite their important strengths, they often fail to pursue issues of external validity or replication, an important direction for social science generally. In this article, I begin with the premise that at least some case studies can and should contribute to a growing body of research within sociology aimed at replication and promoting exte ...
... The statistical design of experiments methodology (DoE) has been a valuable tool since its conception for the understanding of the relationship between factors and responses. Although it has been employed successfully in different research fields and industries for years, its application to the evaluation of lithium-ion batteries (LIBs) is just getting recognition. LIBs are one of the most promisi ...
... City sustainability evaluation has a positive effect on guiding urban economy toward efficiency, stability and innovation with minimal resource consumption. This paper evaluated the sustainability level of Urban Agglomeration on the West Side of the Straits (WSS) in China from three dimensions: economy, society, and environment. We proposed a weighting method based on the hybrid GRA (HGRW) to calc ...
... The purpose of this study is to provide empirical evidence for the sharing-based product service system (sharing-based PSS), a new type of PSS, to achieve sustainable performance in sharing economy context. A multiple case study method was applied, in which 20 semi-structured interviews were conducted with key respondents from three transport sharing economy companies (i.e., OfO, Mobike, and Man-b ...
... In this work, we describe the integration of Weather and Research Forecasting (WRF) forecasts produced by CIMA Research Foundation within ITHACA Extreme Rainfall Detection System (ERDS) to increase the forecasting skills of the overall early warning system. The entire workflow is applied to the heavy rainfall event that affected the city of Palermo on 15 July 2020, causing urban flooding due to an ...
... The pancreatic islets of Langerhans are biomedically important because they are home to the beta cells that secrete insulin and are hence important for understanding diabetes. They are also an important case study for the mechanisms of bursting oscillations and how these oscillations emerge from the electrical coupling of highly heterogeneous cells. Early work has pointed to a voting/democratic pa ...
... The energy modeling has been recognized as an effective analytical methodology and management tool that helps to predict the energy consumption and to manage the efficiency and performance of energy utilization. With a wide distribution and large amount of energy consumption at a low efficiency, the mechanical manufacturing industry has considerable energy saving potential. In this study, a new me ...
... The statistical characterization of extreme floods largely benefits from the reconstruction of historical floods, making use of various documentary sources and of hydrodynamic models. The two-dimensional (2D) modelling approach provides a higher accuracy and detail with respect to one-dimensional (1D) modelling. On the other hand, 2D models require a large amount of topographic and hydraulic infor ...
... Identity is a concept that has received a multiplicity of very diverse approaches and references throughout the history of ideas. Cultural studies have approached with special interest the discussion around the contemporary meanings of this term. This study proposes the concept of gastronomic identity and examines its definition based on Stuart Hall's research on discursive identity. The explanato ...
... In calibration of model parameters for discrete element method (DEM) based models the focus lies on matching the mean key performance indicator (KPI) values from laboratory experiments to those from simulation results. However, due to the stochastic nature of granular processes experimental results can show large variances. To include stochastic behaviour, interpolation-based and regression-based ...
... Despite the positive impacts of an increasing number of organisational initiatives and campaign groups, unequal access to the countryside remains an intransigent issue. Contesting the countryside’s normative associations is thus not just a conceptual challenge but a practical one for organisations managing rural sites. Taking the National Trust-run site of Wembury in Devon, UK, as a case study, I ...

Abstract:
... Understanding how useful any particular set of event data might be for conflict research requires appropriate methods for assessing validity when ground truth data about the population of interest do not exist. We argue that a total error framework can provide better leverage on these critical questions than previous methods have been able to deliver. We first define a total event data error appro ...

Abstract:
... To reduce the negative impact of the conventional vehicles, governments and authorities try to provide facilities in order to encourage people to use electric vehicles. For this purpose, determining the location and the number of charging stations is of paramount importance. It becomes more challenging when some charging stations cannot provide service due to the disruption or breakdown. In this p ...

Abstract:
... Over the past years, there has been an increasing scientific interest in Low Voltage DC grids as an alternative to traditional Low Voltage AC grids, driven by the energy transition. However, fault detection and protection of LVDC microgrids still poses an important challenge for their breakthrough on a large scale. Due to the required speed and reliability of LVDC microgrid protection, an increasi ...

Abstract:
... Asphaltene deposition is an increasing problem in many oil fields around the world. One of the most common strategies to mitigate asphaltene deposition is based on the continuous injection of asphaltene inhibitors. These chemicals are usually screened in the laboratory following one or more of the many techniques available to evaluate their performance, such as precipitation tests or deposition te ...

... Avoiding and controlling dam crest cracking is one of the most difficult problems facing high core rockfill dams of more than 100 m. However, few studies have been conducted on the characteristics and causes of dam crest cracking based on long-term measurement data. In this study, a real case of a dam suffering cracking at the crest was studied. The dam has a maximum height of 186 m and has been i ...

... This study presents an alternative vertical total electron content (VTEC) anomaly detection technique based on diurnal VTEC values. In order to assess the consistency of the results, Mw7.9 Wenchuan earthquake occurred on May 12, 2008 was chosen as case study because several researches were performed on this earthquake event. In this detection technique, the daily mean of VTEC (AVTEC) and standard ...
... The large size of modern datasets has inspired a variety of strategies to alter genes, sites and/or species compositions to improve the accuracy of phylogenetic reconstructions. Each of these data-filtering approaches leads to the exclusion of different types of data, which is known to affect phylogenetic outcome. However, the choice of a filtering strategy is often subjective and the robustness o ...

Abstract:
... Practitioners are generally not willing to explore modern reactions where considerable synthetic effort is required to generate materials and the results are not certain. Organocatalysis exemplifies this, in which a broad set of enantioselective reactions have been successfully developed but further applications to include additional substrates are often not performed. Herein we demonstrate how st ...
