A Model for Detecting Movement in Railway Infrastructure Using Deep Convolutional Neural Network
No full textThe continuous monitoring of movements using artificial intelligence technique has become a necessary system to cob the level crossing problems faced around the railway infrastructure. This project work has developed a model for detecting movements using image processing method with convolutional neural network, an artificial intelligence technique in monitoring and detection of movements in the railway infrastructure. Images containing movements and non-movements in railway infrastructure were acquired from Google image search have been used in the implementation of the system and a deep convolutional neural network model has been developed. The proposed model was able to classify 11 out of 12 images correctly in the evaluation of the train dataset and the performance accuracy of the model recorded was 92% with a loss of 0.4% which resulted to the misclassification of one of the images. The analysis of the system showed that the system can be optimized to perform better

Automatic Control System for Lifting and Condition Control of Moving Moldes Used in The Construction of Vertical Monolithic Buildings and Structures
No full textThis article aims to introduce the use of automatic control systems for lifting and controlling the position of sliding formwork used in the construction of vertical monolithic buildings and structures. In this regard, the relevance of using programming languages in the CodeSys environment when controlling the position of vertical sliding formwork devices is considered
IMPROVING THE EFFICIENCY OF TACTICAL ACTIVITIES IN EMERGENCIES
No full textThe article describes the measures for the effectiveness of operational and tactical actions in order to reduce the scale of the outcome of emergency situations
STUDY OF THE EFFECT OF NEW FIREFIGHTING COMPOSITIONS ON THE THERMAL PROPERTIES OF WOOD PARTICLES
No full textThe article presents a differential scanning analysis of samples treated with new formulations for fire extinguishers in which endothermic and exothermic processes were not observed. This situation is confirmed by the fact that the thermal properties of impregnated wood particles in the new composition are much more effective than those of others. By the end of the test experiments, it was determined that the loss of mass as a result of thermal effects on the duration of time of wood particles coated with bentonite and existing SiO2 suspensions, with a surface part, can vary greatly compared to untreated wood
STUDY OF THE TECHNICAL CONDITION OF THE CONSTRUCTION OF THE BIBI-KHANYM MOSQUE
No full textIn this article were analyzed the structures and assesses the technical condition based on the existing data of the Bibi-Khanum Mosque in the city of Samarkand. The damaged and reinforced conditions of the mosque structures were compared, and appropriate conclusions were drawn on the technical condition. Information about the centuries-old history of the mosque and its restoration is presented
Hygienic assessment and ways to optimize water use for rural and urban population in the Republic of Uzbekistan
No full textThe most accessible source of water is now considered to be a centralized water supply system. It is used in the preparation of hot food, drinks, and for drinking raw. The high quality of drinking water is the result of an integrated solution, the main of which are the development and implementation of modern water treatment technologies, the use of social and hygienic monitoring, an integral approach to assessing the quality of drinking water.

Assessment of Science Resources in Higher Education
No full textThis study assessed the availability, adequacy and utilization of science resources. These science resources were categorised as audio, visual, audiovisual resources, and reference materials. Three research objectives and questions were raised for the study. The study adopted the descriptive research design. The population of the study comprised of the entire academic staff of the University of Abuja, Nigeria. The sample size used was made up of 293 lecturers from 2 sampled Institutions of the university (Institute of Education, and Centre for Distance Learning and Continuing Education). Data were analyzed using descriptive statistics of mean, standard deviation. Results showed that science resources that involves audiovisual materials were available but not adequate, and not effectively utilized by academic staff and students. However, reference materials such as textbooks and posters were sufficiently utilised in the classroom setting. Based on the results of the findings, it was recommended that government and stakeholders should endeavour to adequately procure and effectively utilise the science resources available in other to enhance the acquisition of necessary science skills, especially in ICT which is the new normal
