The improvement of refrigerator wagons is an essential problem in Russia. Different tasks need to be solved. One of them is the improvement of bogie dynamics properties. The authors have developed mathematical models for simulating the dynamics of the refrigerator railway vehicle. The aim of the paper was to determine the experimental condition for theoretical results verification and obtain new information about the wagon. Accelerometer schemes on the bogies and wagon body were obtained that made possible to measure all bogies movements and investigate the influence of longitudinal dynamics on flexible carbody accelerations.

The object of research is the problem of texture image segmentation. The subject of the research is to improve one of the components of the texture segmentation algorithm, namely the acceleration the process of calculating the gray level co-occurrence linked list. The paper presents a new method for computing the linked list, and compare the execution time calculation linked list by traditional and proposed methods.
