石家庄信息工程职业学院（Shijiazhuang Information Engineering Vocational College）是石家庄市人民政府举办，教育部备案的公办全日制高等职业院校。学院前身是始建于1963年的石家庄地区专员公署商业学校。1993年，学校更名为石家庄市财经学校。1999年，原石家庄市财经学校、第一商业学校、第二商业学校和财贸干部学校合并，成立新的石家庄市财经学校。2002年升格为石家庄信息工程职业学院。2004年石家庄市纺织技工学校并入学院。截至2019年11月，学校分东、西两个校区，总占地面积1932.8亩，一期工程占地1501.5亩，建筑面积47.3万平方米，教学科研仪器设备值14446.62万元；下设9系4部1学院，开设42个专业；有在校生19000余人。
This paper proposes an infrared weak-texture image enhancement method based on guided filtering, LoG-CLAHE, and sigmoid-gamma correction. Guided filtering is first used to decompose the input image into base and detail layers. The base layer is enhanced by LoG-CLAHE to improve local contrast and edge-related details, while the detail layer is processed by sigmoid-gamma correction to strengthen weak texture responses. The two processed layers are then fused to obtain the enhanced image. Experiments on three outdoor infrared weak-texture scenes show that the proposed SGLC method improves local texture visibility and edge clarity. Compared with the selected methods, SGLC obtains the highest MLIE and AG values in the three scenarios, while its FCE values remain competitive. The results indicate that SGLC provides a balanced enhancement effect for the tested infrared weak-texture images.
To address the conflict between aesthetic expression and functional efficiency faced by renewable energy facilities in urban spaces, this study proposes a public art installation design framework that integrates interdisciplinary technologies. A multi-source data fusion module integrates geographic context and regional cultural symbols to jointly guide the parametric optimization of device morphology and the layout of energy harvesting components. Complementing this, an improved MPPT (Maximum Power Point Tracking) algorithm—enhanced by a Kalman filter-based dynamic allocation strategy—ensures robust power extraction under the complex irradiance fluctuations induced by the artistic form. Meanwhile, a parametric aesthetic generation algorithm based on genetic algorithm morphological optimization and CycleGAN (Cycle-Consistent Generative Adversarial Network) texture fusion is developed to achieve the dual goals of urban public art as a renewable energy hub. Structural strength verification and interactive experience design ensure safety and public engagement, respectively. Experimental results demonstrate that the proposed scheme achieves a power generation efficiency of 93.4% of the theoretical value under sunny conditions, with a high public satisfaction rate of 85%. A measured annual internal rate of return of 10.6% verifies its environmental and economic benefits. This research provides an innovative paradigm for the synergy between aesthetics and functionality for sustainable urban development.
China has implemented policies to encourage pre-service teachers' teaching commitment, yet their intrinsic teaching motivation remains insufficient. Existing studies on internship environments and motivation overlook spiritual role models and intrinsic motivation's significance. Integrating Social Learning Theory and Self-Determination Theory, this study explored how Practicum Mentors' Embodiment of the Spirit of Educators affects pre-service teachers' intrinsic teaching motivation, and the mediating roles of Teaching Self-Efficacy and Professional Identity. A questionnaire survey of 688 pre-service teachers used a self-developed Scale for Practicum Mentors' Embodiment of the Spirit of Educators and mature scales for the other three variables. Results revealed that Practicum Mentors' Embodiment of the Spirit of Educators had a significant positive impact on Pre-Service Teachers' Intrinsic Teaching Motivation; Teaching Self-Efficacy and Professional Identity played both independent and serial mediating roles. Findings extend the Social Learning Theory and Self-Determination Theory to the context of China's Spirit of Educators and inform optimizing mentor selection, pre-service teacher programs, and talent cultivation in other mentorship-based fields.
