Personalized day tour design for urban tourists with consideration to CO_(2) emissions

The growing awareness of climate change worldwide has led the urban tourism market to focus on balancing tourist tailored experiences and CO_(2) emissions.Therefore,designing personalized tourist routes with environ‐mental pollution consideration is preferable in this context.This study proposes an evolution algorithm based on reinforcement learning(FSRL-HA)to design a personalized day tour route that simultaneously considers the utility of tourists and the carbon emission.We conducted a case study in Chengdu,Sichuan,China,to evaluate this algorithm's performance.The results indicate that the proposed algorithm outperforms selected baseline methods.Furthermore,the approach can provide more diverse route choices for different tourists,and an experiment was conducted to explore how tourist preferences affect tourist utilities.

Leather personalized study design in intelligent customization

The rich and colorful leather design brings a broad stage of fashion design in the past, China＇s leather （leather） clothing brand single, old style, color： black, blue, is brown. The economic and cultural development, leading the fashion changes, the concept is also constantly promote the development of a new direction, to the consumer, aesthetic with the change of consumption concept, the fur （leather） apparel consumption presents a civilian, personalized, ideal trend, leather （leather） clothing to reflects personal charm and style of the clothing style, design aesthetic appreciation, knowledge and other aspects of the new technology and new materials to absorb human body art is to stimulate leather （leather） the change of clothing. With the continuous development of science and technology, intelligent garment customization to the majority of consumers, the effect of intelligent custom fur （leather） three direction costumes （fabrics, colors, styles） for innovative research, get a Of leather （leather） costumes to break the current leather （leather） styles of dull shape, rich leather （leather） and other clothing charm, for the fur （leather） costumes to all ages personality need to provide ideas and new development space.

Selective Laser Melting Molding of Individualized Femur Implant:Design,Process,Optimization

Efective Selective Laser Melting(SLM)molding methods for femur implant design and molding can improve femur implant surgerysucess rates and enhance patients quality of life.In this study,an individualized femur implant and individualized biological fixed-typefenur implant were designed using the parametric modeling method.The implants were then directly manufactured via SLM moldingtechnology as the forming process was carefuly analyzed.The results indicate that the proposed implant allows for favorable conjunctionof the reconstructed implant model with the surrounding bone tissues under the premise of a relatively small amount of bone-cutting.Theproposed implant also shows even pore distribution,good overall connectivity,relatively high bearing capacity,favorable overlappingbetween supports,and strong inter-pore connectivity.Only a small amount of powder adheres onto the surface and can be directly usedafter simple sand blasting and polishing.The comprehensive analyses of fenur implant modeling and molding methods given in this papermay provide a sound foundation for the design and direct manufacture of individualized femur implants in the future.

Personalized Design Method of Bionic Bone Scaffold with Voronoi Spacial Architecture

In order to design and manufacture a bionic bone scaffold for personalized bone tissue repairing,we give the performance requirements and indicators,and propose a method of establishing a three-dimensional bone scaffold solid model based on the Voronoi architecture.The modeling parameters,number of seed points and scaling factor are found,which can control the model performance.The finite element analysis model of bone scaffold with different number of seed points and scaling factor is set up.By adopting the method of theory analysis,experiment and simulation calculation,the performance parameters of the porosity,the specific surface area and the elastic modulus of 15 sets of bionic bone scaffold model are obtained.The relation between the bone scaffold model parameters and the porosity,the porosity and the specific surface area,the porosity and the equivalent elastic modulus are established.The individual design method of Voronoi bone scaffold is proposed.In the condition of given equivalent elastic modulus and the defected shape of bone,the bone scaffold model with spatial Voronoi architecture which accords with the performance requirements can be designed and produced rapidly,which provides reference for the personalized treatment of bone defecting.
