This study focuses on modeling the thermodiffusion process and thermal stresses using the finite element method (FEM). The paper examines algorithms for polygonal mesh generation and evaluates the influence of mesh quality on the accuracy of numerical methods in thermodiffusion calculations within solid bodies. An improved Delaunay algorithm is proposed to enhance mesh construction. Numerical experiments are presented, and the accuracy of the obtained results is analyzed to demonstrate the effectiveness of the proposed approach in accelerating thermal stress calculations.

The article considers the problem of classifying objects according to indistinctly expressed features in the intelligent control system (ICS) of a robot. A method and algorithm for classifying objects with indistinctly expressed features in the intelligent control system of the robot have been developed. It is proposed to solve the problem on the basis of a complex indicator that takes into account both the degrees of belonging of the features of the recognized object to the features of one of the classes of objects, and the weight coefficients of each feature. An improved weighted Mahalanobis distance was chosen as an indicator, taking into account the fuzziness of the features by which objects are classified. The proposed method is considered by the example of solving the problem of classification (sorting) of ceps in the ICS of a mushroom sorter robot. The efficiency of the proposed method is confirmed by the results of a computational experiment. This method can be implemented in the development of software for classifying objects according to indistinctly expressed features when controlling intelligent robots in areas where there is disorganization of the operating environment.

Tokenization of communities is a new field of study that has emerged at the intersection of informational technology and social and economic sciences. This paper identifies the main tools for tokenizing communities, the existing approaches to implementing these tools, the challenges of tokenized communities, and methods for addressing these challenges to develop a comprehensive system for community tokenization.

The paper considers the features of mobile applications for people with intellectual disabilities and defines the requirements for the development of such applications. The technology of end-to-end development of mobile applications for users with intellectual disabilities is described, based on the use of a template multi-module architecture and an adaptable template interface. A CASE system is proposed that implements support for the stages of design, implementation and maintenance of the life cycle of mobile applications for people with intellectual disabilities. An example of using the CASE system for developing a mobile game for people with severe multiple developmental disabilities is described.
