The aim of this paper is to define the productoperation on a family of interval valued events and the notion ofjoint interval valued observable. We show the connection betweenproduct operations for interval valued events and intuitionisticfuzzy events, too. We display the relation between joint intervalvalued observable and joint intuitionistic fuzzy observable. We...

In the field of explainable artificial intelligence (XAI), post-hoc interpretability methods aim at explaining to a user predictions trained decision model. Integrating prior knowledge into such aims improving explanation understandability and allowing for personalised explanations adapted each user. this paper, we propose define cost function that explicitly integrates objectives: present gene...

A porous debris bed formed after a severe accident is structure composed of different sized particles. Due to the fission reaction in bed, decay heat continuously released. Therefore, cooling ability should be investigated determine safety bed. In this paper, two-phase conservation equations with closure correlations are proposed for boiling phenomenon inside pool. For flow resistance, drag for...

Abstract In this paper, the wind turbine of NREL 5MW is used as research object, and simulated from yaw-to-wind angle 30°-0° at different yaw angular velocities (0.5°/s, 1°/s, 2°/s) under rated operating conditions by using slip grid model in fluent solver custom UDF function program. The output characteristics aerodynamic dynamic are studied, effects velocity on power, near wake speed analyzed...

Data analytics has recently grown to include increasingly sophisticated techniques, such as machine learning and advanced statistics. Users frequently express these complex analytics tasks as workflows of user-defined functions (UDFs) that specify each algorithmic step. However, given typical hardware configurations and dataset sizes, the core challenge of complex analytics is no longer sheer d...

Modeling thermal comfort provides quantitative evidence and parameters for effective and efficient urban planning, design, and building construction particularly in a dense and narrow inner city, which has become one of many concerns for sustainable urban development. This paper aims to develop geometric and mathematical models of wind and thermal comfort and use them to examine the impacts of ...

An oil spill accident will cause serious harm to marine ecology and the environment. Rapid response effective prevention methods are required minimize damage of accidents. The critical problems that emergency rescue teams face when spilled reaches sea surface, extent oil, how far they from drilling platform. However, there is no reliable model predict diffusion distance oil. Accurately predicti...
