Problems Of The State Of The Rolling Surface Of The Rail Head On Speed And High-Speed Railway Sections Of Jsc "Uzbekistan Temir Yollari", Kuvandik Saginovich Lesov, Igor Ivanovich Kuznetsov, Mukhamedali Kazbek Ugli Kenjaliev, Xushnudbek Odilbekovich Samandarov

Journal of Tashkent Institute of Railway Engineers

In the process of train traffic on the rolling surface of the rail head are formed bumps and fatigue defects, constant dynamic loads lead to the frustration the upper structure of the path. In this article the analyzes integral indicators of the rolling surface of the rails (long waves, medium waves, short waves) on the section of speed and high-speed train traffic for assess the condition of rails in transit. Problems with the formation of wave-like irregularities on the surface of the rails are identified, promising directions in solving this problem are indicated.

The Causal Relationships In The Management Process Of Cement Production, Alishev Sh., Ortikov Z.

Problems of Architecture and Construction

In the article on the basis of cause-effect relationships in cement, which are both direct and reverse in nature, it is revealed that the compressive strength of concrete largely depends on the reactivity of the anhydrous compounds obtained during firing, the fineness of grinding, the amount of free lime and other oxides, as well as a great influence on the quality of cement has a fine grinding of raw materials. Results of calculation of standard deviations. The models are obtained on the basis of the results of chemical analysis and individual expressive data of physical and mechanical character, on the …

Drones On The Rise: Societal Misperceptions Of Small Unmanned Aircraft Systems, Renee Keilman

The Journal of Purdue Undergraduate Research

Throughout the past decade, small unmanned aircraft systems (sUAS) have been on the rise in both the civilian and military sectors. It is forecasted that in the near future they will create thousands of jobs and billions in tax revenue due to their ability to execute difficult and hazardous tasks safely, efficiently, and cost-effectively. However, one current issue with the proliferation of the technology is a shortage of skilled employees due to a lack of education and common negative public misperceptions associated with them.

To investigate this, responses from a mixed-methods survey will be analyzed. Within the survey, questions such …

Big Five Technologies In Aeronautical Engineering Education: Scoping Review, Ruth Martinez-Lopez

International Journal of Aviation, Aeronautics, and Aerospace

The constant demands that technology creates in aerospace engineering also influence education. The identification of the technologies with practical application in aerospace engineering is of current interest to decision makers in both universities and industry. A social network approach enhances this scoping review of the research literature to identify the main topics using the Big Five technologies in aerospace engineering education. The conceptual structure of the dataset (n=447) was analyzed from different approaches: at macro-level, a comparative of the digital technology identified by cluster analysis with the number of co-words established in 3 and 8 and, a keyword central structure …
