In order to improve the efficiency of sentiment analysis of students in ideological and political classrooms, under the guidance of artificial intelligence ideas, this paper combines data mining and machine learning algorithms to improve and propose a method for quantifying the semantic ambiguity of sentiment words. Moreover, this paper designs different quantitative calculation methods of sentiment polarity intensity, and constructs video image sentiment recognition, text sentiment recognition, and speech sentiment recognition functional modules to obtain a combined sentiment recognition model. In addition, this article studies student emotions in ideological and political classrooms from the perspective of multimodal transfer learning, and optimizes the deep representation of images and texts and their corresponding deep networks through single-depth discriminative correlation analysis. Finally, this paper designs experiments to verify the model effect from two perspectives of single factor sentiment analysis and multi-factor sentiment analysis. The research results show that comprehensive analysis of multiple factors can effectively improve the effect of sentiment analysis of students in ideological and political classrooms, and enhance the effect of ideological and political classroom teaching.

Taking the configuration design of the lifting device in a bridge crane as an example, this paper discusses the green optimal design method of enterprise's modular products with uncertain factors. The multi-layer generalized operators and comprehensive mathematical model under uncertainty are established based on the mapping relationship between product function and its structure. The model is transformed to an ascertaining combinatorial optimization model by de-fuzzy operator, and then it is solved by GA (Genetic Algorithm, GA). The method of chromosome encoding in binary that the chromosome is segmented by components and the genes in each segment are ranged as corresponding structures of each component, and the methods of selection and crossover and mutation operator are presented in this paper. The result of the green configuration design on the lifting device verifies the effectiveness and practical value of the method proposed in this paper.

To solve the problem on the indeterminacy of customers’ demands, a new fuzzy configuration design based on decision table is presented. Generalized product configuration model is proposed and taken as the basic of configuration design. Generalized product configuration model is composed of generalized product structure BOM,structure-function units and configuration rules. Configuration rule is expressed with decision table, and it constrains the process of the configuration design. Fuzzy theory is applied in configuration design. Configuration engine accesses decision table and carries out the configuration reasoning with fuzzy theory in configuration design. Finally, the application on the transmission system of wind turbine verifies the feasibility and validity of this method.

A new QFT design method for SISO cascaded-loop design, which is different from the conventional inner-outer procedure and the outer-inner procedure, is proposed in this paper. The desired uncertainty of the inner loop after closure is prescribed as a design specification before designing the inner controller, which is done by introducing an appropriate weight function. The inner loop design, therefore, is transferred into a sensitivity reduction problem. Then, the outer-loop design becomes that of a plant with mixed uncertainty which can be carried out as usual. In this method, the weight function is an important design factor, which actually allocates the control burden between the inner and outer controllers. This method not only removes the arbitrariness in the closure of the inner loop in the inner-outer procedure, but also can reduce the number of iterations needed, which therefore could give a significant reduction in the outer controller bandwidth as is demonstrated in two examples.

With the improvement of the social civilization, culture connotations of design problems have become increasingly prominent. And the cultural elements must integrate into design work to get development. Since cultural and creative product design is the re-exhibition of culture, traditional culture spirit connotation and cultural nutrition should be grasped and absorbed. Reverse engineering is a very important design method which is widely used in product design. Based on reverse engineering, a rapid and high quality creative design method over cultural and creative product design is proposed. The practical design application proves that the proposed method is feasible, of practical significance and application value.

Pavement design is the process of calculation the thickness of pavement layers which can withstand the expected traffic load over the design life without deteriorating. In another word, it is providing a pavement structure in which stresses on the subgrade are reduced to the acceptable magnitude. Highways in Sudan deteriorate in the first years of construction due to many reasons including the deficiency in pavement design. This research aims to minimize the probability of roads failure by selecting the appropriate pavement design method for Sudan based on the performance evaluation of each method. Various pavement sections with different environment, traffic loading, subgrade and material properties were designed using AASHTO, Road Note 31, Group Index and CBR design method. The layered elastic analysis and the structural number approach were adopted to evaluate the performance of these sections. The evaluation results were the base for selecting of the suitable design method. The evaluation results concludes that, the AASHTO design method is the most suitable design method to withstand pavement deformations followed by Road Note 31 method. But, from economical prospective Road Note 31 method; with some modifications; can be considered as the suitable design method for Sudan. Recommendations for future studies focus on the development and implementation of mechanistic-empirical pavement design guide applicable in Sudan.

This report introduces techniques involving novel calculation methods developed by the Electric Power Research Institute and Bechtel Marine Propulsion Corporation [1] that can be used to develop an improved understanding of welding factors affecting substrate weld heat input and dilution. These improved calculation methods are especially warranted in ASME BPVC Section XI repair and replacement welding activities such as mitigation of hot cracking (dilution control) and optimization of temper bead welding (heat input control). Various parameter sets are tested to demonstrate the effectiveness of the new calculation methods and how they can be refined in future studies to further improve accuracy. Additionally, this report highlights the limitations associated with the ASME BPVC Section IX theoretical heat input and power ratio calculation methods widely used in the welding industry for control of substrate heat input and weld dilution. Weld trials are performed in this study to demonstrate the limitations and determine proper precautions to take when using the calculation methods.
