The rise in generative large models has gradually influenced traditional product design processes, with AI-generated content (AIGC) playing an increasingly significant role. Globally, tourism IP cultural products are crucial for promoting sustainable development. However, there is a lack of practical methodologies incorporating products. Therefore, this study proposes methodology the color matching and shape using multimodal models. process includes four phases, as follows: (1) GPT-4o used...

Deep learning approaches for multimodal aspect-level sentiment classification (MALSC) often require extensive data, which is costly and time-consuming to obtain. To mitigate this, current methods typically fine-tune small-scale pretrained models like BERT BART with few-shot examples. While these have shown success, Large Vision-Language Models (LVLMs) offer significant advantages due their greater capacity ability understand nuanced language in both zero-shot settings. However, there limited...

Sharing information across different organizations is a critical problem. Using security enforcement mechanisms, accessing databases limited to authorized users only. However, if and access control policies are syntactically schematically heterogeneous, interoperation becomes crucial challenge. In order allow from multiple databases, better model desired. this paper, we propose Semantic Access Control based on popular Role-Base Control. provides secure while resolving the heterogeneity among...

A product form design and evaluation model are proposed. In this method, the forms can be evaluated by three sub-evaluation models which help designers to grasp consumers’ preferences. process, overall shape is first disassembled into several elements, a morphological chart constructed. Then, priority of elements analyzed through fuzzy analytical hierarchy required combinations selected from chart. Moreover, comprehensive (I), preference questionnaire (II), quadratic curvature entropy (III)...

This paper combines the rough set with graph theory to deal problems of power transformer fault diagnosis, by decision table for diagnosis and its partitioned adjacency matrix. In process, new three-ratio based on an d is got without conflict missing, derive rules. These rules core attribute this can expand range guideline IEC-60599, improve defect problem three-radio method. The results experiment 62 samples transformers prove effectiveness

With the spread of COVID-19 worldwide, various travel restrictions are becoming a significant trigger for anxiety. Although healing products could relieve anxiety, few scholars have proposed practical design strategy. Therefore, we offer strategy that includes three phases: preparation, analysis, and verification. In Phase 1, 20 people with moderate or high anxiety invited to rate 100 samples. Then, FCM is used obtain representative 2, three-layer diagram (incl. upper, middle, lower layers)...

Form aesthetic principles represent an consciousness developed through long-term human labor practices, which are crucial for the design and evaluation of product form. The equilibrium principle is a vital component form principles, significantly influencing other principles. This study introduces method using improved measurement formula that incorporates number elements structured in three phases: (phase 1), 2), analysis 3). In phase 1, primary functional units (form elements) target...

Business process describes a set of services that span enterprise boundaries and are provided by enterprises see each other as partners. Web is widely accepted adopted to construct business process. built in exposed environment open security threats. When web service contained authorized illegal users, it will cause economic loss the provider. Although there exist some standards for access control distributed systems well studied, lack comprehensive approach services, especially In this...

For design education, although different international organizations have developed thinking models (DTM), these DTMs mainly focus on improving innovation but ignore the actual demands of users. This paper proposes a consumer-oriented DTM to implement and evaluation based accurately grasping users' demands. The consists three phases, namely preparation, creation evaluation. In preparation phase, grid method is used obtain three-layer demand chart from skilled users; this then questionnaires...

City bicycles have become popular worldwide because they play an essential role in releasing urban traffic congestion and are environmentally friendly. Since wheelsets the most prominent shape element a bicycle, this research explores influence of various wheel types on visual image city bicycle. First, 10 with high market share China were selected as samples. Meanwhile, vocabularies suitable for describing chosen from many vocabularies. Then, all summarized into six adjectives using factor...

This paper introduces the safe situation of coal production and current data driven applications in mine safety early warning. Through analysis monitoring accidents, this presents a fault diagnosis method based on principal component BP neural network. The is used to extract information state from data. By establishing network model, extracted then as sample input Research indicates, takes advantages Besides, it can effectively characteristics achieve

As far as product design education is concerned, traditional classroom teaching mostly uses desktop research, simple field investigation and non-rigorous interviews the main means, which often fails to accurately systematically grasp users' real needs preferences. The purpose of this study explore new path education, stimulate students' creativity, ensure that conceptual scheme designed by students captures user Firstly, are required collect sample data object through market research patent...

Preventing land desertification is one of the 17 sustainable development goals United Nations, which can effectively promote desert greening. Currently, tree plantation most effective way to achieve this goal. However, existing tree-plantation activities have some imperfections, including low efficiency, labor-intensiveness, challenging environments, and survival rate saplings. Therefore, contribute greening, paper presents a practical tree-planting vehicle based on scientific design...
