The Role Of Network Components In Improving The Reliability And Survivability Of Mobile Communication Networks, Dilmurod Davronbekov, Utkir Karimovich Matyokubov
The Role Of Network Components In Improving The Reliability And Survivability Of Mobile Communication Networks, Dilmurod Davronbekov, Utkir Karimovich Matyokubov
Acta of Turin Polytechnic University in Tashkent
This article compares the different architectures of mobile communication networks (MCN) and examines the survivability of the network. Typical survival strategies for improving MCN survivability, failure mitigation strategies for network elements, wireless network survival rates, failure scenarios at MCN levels, and survival indicators are presented. The importance of fiber-optic communication in the construction of communication lines between MCN components has been studied. The issue of designing MCNs in a cost-effective and highly viable way is considered, and the necessary expressions of the design process are given.
Malfunction Analysis In The Freight Cars Used In Uzbekistan And Measures For Their Elimination, Nodir Botirovich Adilov
Malfunction Analysis In The Freight Cars Used In Uzbekistan And Measures For Their Elimination, Nodir Botirovich Adilov
Journal of Tashkent Institute of Railway Engineers
This article uses the analysis of malfunctions of the load-carrying apparatus of freight car structures used in Uzbekistan. The reasons for the occurrence of malfunctions in the load car structures are studied. It seems that in order to determine the technical condition of the device, it is possible to increase the reliability of the stored device by making the correct conclusion from the fault signs derived from the design parameters using information received from the controlled stands.

Journal of Tashkent Institute of Railway Engineers
With the acquisition of independence of our Republic in the system of transport communications, great importance was attached to the qualitative improvement of the design, construction, and operation of aboveground structures. Many tasks have been performed to increase the reliability and strength analysis of these bridges. Along with these, improving methods for calculating the resource of artificial structures in the system of transport communications are required. The Strategy for the Further Development of the Republic of Uzbekistan, including the following tasks: "... implementation of targeted programs for the development and modernization of road transport, engineering, communication, and social infrastructures, ...". …
Method For Evaluating The Residual Resource Of Long Designs, Sergey Vladimirovich Chizhov, Ulugbek Zabixullayevich Shermuxamedov, Sharofat Shavkatovna Kadirova
Method For Evaluating The Residual Resource Of Long Designs, Sergey Vladimirovich Chizhov, Ulugbek Zabixullayevich Shermuxamedov, Sharofat Shavkatovna Kadirova
Journal of Tashkent Institute of Railway Engineers
The article describes a method for calculating the safety of extended structures, in particular tunnels. The probabilistic approach to solving the problem is analyzed using the reliability of the structure with the probability of failure-free operation and assessment of the residual life of the structure. These characteristics make it possible to predict the residual life of the structure within a time value until the design has exhausted its ultimate state. An assessment of the operational reliability of the structure is carried out by measuring and establishing existing structural defects. Based on the data obtained, an analysis was carried out and …
