Isight is introduced as an integration platform. The construction of this platform is based on the user programming and several commercial software including UG6.0, GAMBIT2.4.6 and FLUENT12.0. An intelligent parameter optimization method, the particle swarm optimization, is incorporated into the platform. To verify the strategy proposed, a simulation is conducted on the underwater robot model 5470, which originates from the DTRC SUBOFF project. With the automatic optimization platform, the minimal resistance is taken as the optimization goal;the wet surface area as the constraint condition; the length of the fore-body, maximum body radius and after-body＇s minimum radius as the design variables. With the CFD calculation, the RANS equations and the standard turbulence model are used for direct numerical simulation. By analyses of the simulation results, it is concluded that the platform is of high efficiency and feasibility. Through the platform, a variety of schemes for the design of the lines are generated and the optimal solution is achieved.

Firstly,considering some factors like primary user's( PU's) collision limitations,non-synchronization between SU and PU,and SU's limited buffer size, the short-term optimization problem was formulated as a mixed integer non-linear program( MINLP) to minimize the block probability of video packets. Secondly,combining the minimum packet block probability obtained in shortterm optimization and SU's constraint on hardware complexity,the partially observable Markov decision process( POMDP) framework was proposed to learn PU's statistic information over DCRNs.Moreover,based on the proposed framework,joint optimization strategy was designed to obtain the minimum packet loss rate in long-term video transmission. Numerical simulation results were provided to demonstrate validity of our strategies.展开更多

In the era of scarce educational resources, teachers are the owners of knowledge. However, when the emergence of the Internet puts a huge amount of knowledge in front of people, what is scarce in education is no longer the amount of knowledge, but the selection, carding, promotion and internalization of knowledge. The traditional teaching method is transforming into learner centered individualized teaching and learning. In the process of teaching and learning, the proportion and focus of knowledge transfer and knowledge internalization have also changed. Under the new environment, teachers need to change the habits of teaching and learning for thousands of years, and carry out teaching in innovative mode through new technical means, so as to achieve higher results. However, in the new technology environment, if there is no complete teaching logic and the organic connection and cooperation between man and machine, classroom teaching will not present an orderly and efficient situation. If there is no good teaching design and the new educational technology is used freely, the teaching effect may not be as good as the traditional blackboard teaching mode.展开更多

文摘The school commuting path is an important space for elementary school students to engage with society and nature.The design of these paths reflects concerns for children's rights and healthy development and has crucial impacts on creating supportive environments for children.The scientific evaluation of the child-friendly level of school commuting paths forms a significant basis for shaping child-friendly environments and promoting the comprehensive development of children.Additionally,due to the unique climatic conditions,cold climate cities excert a distinct impact on children's behavior,activities,and physical and mental health compared to cities in other climate zones.This study,from the perspective of child-friendliness,constructs an evaluation system for school commuting paths in cold climate cities,based on children's behavioral characteristics and environmental needs.The system includes dimensions such as safety,diversity,and comfort.With children and their caregivers as the evaluators,the study applies structural equation modeling to assign weights to the various dimension indicators in the evaluation system.The research focuses on five elementary schools in the Nangang District of Harbin City,using methods such as machine learning,space syntax,and field surveys to assess the school commuting paths.Building upon these findings,the study constructs the characteristic profile of the commuting paths and proposes evidence-based control and optimization strategies for different types of school commuting paths in cold climate cities from a child-friendly perspective.
