AbstractThe article deals with selected issues concerning tests results of failures of selected objects used in the analyzed real technical system. The main operation goal of the analyzed system is to provide passengers with safe transport services within a given quantitative range and over a given territory. The analyzed technical objects were transport means. Transport services were provided along scheduled routes. Selected features and characteristics of vehicle failures have been discussed. Vehicles used in the investigated technical object were disassembled for the needs of the research. Tests were performed with the use of the passive experiment method under real service conditions.

The basic tasks of the public public transport operator include reliable and safe transport services under the concluded transport contract with the transport organizer. The entity acting as the operator is obliged to punctually adhere to timetables, it is possible provided that the operator has a rolling stock characterized by a high level of readiness for rolling stock. The paper attempts to assess the readiness of the public transport operator performing tasks in the city and the adjacent area with a total number of residents not exceeding one hundred thousand.

Pumping Equipment

Pumping equipment is one of the main systems of water supply and sewerage, where centrifugal pumps are mostly used due to the simple design and the optimal interval of the parameters of flow and pressure. The paper considers the development of a centrifugal pump from the point of view of system analysis, since this approach considers any technical object as a complex of interacting elements having the properties that are not reduced to the properties of individual elements designed to perform certain useful functions. The aim of the paper is to find patterns of development of the centrifugal pump as a technical system to predict its further evolution. Domestic and foreign patent fund of Class F 04 D in the amount of 724 units was used as the main source. In the paper, the device of the centrifugal pump as a technical system is divided into the following main structural subsystems: impeller blades, impeller disks; housing; pressure pipe and suction pipe. Each of these elements has its main useful function and a number of auxiliaries, which are discussed in detail. It is established that an increase in the degree of control of the centrifugal pump can be achieved by dynamization of transmission, specifically, the regulation of the revolutions transmitted from the engine to the impeller mechanically, with the help of fluid coupling and frequency converters.

Technical Artefact

Since its launch in 2005, Google Maps has been at the forefront of redefining how mapping and positionality function in the context of a globalizing digital economy. It has become a key socio-technical ‘artefact’ helping to reconfigure the nexus between technology and spatial experience in the 21st century. In this essay, I will trace Google’s evolving strategy in the mapping space. I will argue that the evolution of Google Maps exemplifies way in which a contemporary digital platform ‘succeeds’ by becoming embedded as a foundational resource for a variety of other uses and services. At one level, this can be understood in terms of what Gillespie has conceptualized as the ‘politics of platforms’, contributing to the emergence of what has recently been dubbed ‘platform capitalism’. At a deeper level, I will argue that Google Maps exemplifies the complex dynamics of what Simondon calls ‘technical objects’ that always exist in relation to both an evolving technical system, and the other systems constituting a more or less integrated social milieu.

Circuits Vlsi

Trends in the technology development of very large scale integrated circuits (VLSI) have been in the direction of higher density of components with smaller dimensions. The scaling down of device dimensions has been not only laterally but also in depth. Such efforts in miniaturization bring with them new developments in materials and processing. Successful implementation of these efforts is, to a large extent, dependent on the proper understanding of the material properties, process technologies and reliability issues, through adequate analytical studies. The analytical instrumentation technology has, fortunately, kept pace with the basic requirements of devices with lateral dimensions in the micron/ submicron range and depths of the order of nonometers. Often, newer analytical techniques have emerged or the more conventional techniques have been adapted to meet the more stringent requirements. As such, a variety of analytical techniques are available today to aid an analyst in the efforts of VLSI process evaluation. Generally such analytical efforts are divided into the characterization of materials, evaluation of processing steps and the analysis of failures.
