Abstract:

Machines are the heart of most industries. By ensuring the health of machines, one could easily increase the company revenue and eliminates any safety threat related to machinery catastrophic failures. In condition monitoring (CM), questions often arise during decision making time whether the machine is still safe to run or not? Traditional CM approach depends heavily on human interpretation of results whereby decision is made solely based on the individual experience and knowledge about the machines. The advent of artificial intelligence (AI) and automated ways for decision making in CM provi

In order to making the virtual experiment results close to or equivalent to the real environmental effects, in addition to model realistic scenes, also need more accurate dynamic model. In this paper, based on research of hydraulic steering paddy and wheat combine harvester, first, used three-dimensional geometric model transformation technology to convert Pro/E model to a identified geometric model in VP virtual reality systems, second, used classical dynamics equations to build the mathematical model of this vehicle dynamics, finally, used VC++ programs to connect this two models, constructe

This paper investigates the application of process mining methodology on the processes of a mobile asset in mining operations as a means of identifying opportunities to improve the operational efficiency of such. Industry 4.0 concepts with related extensive digitalization of industrial processes enable the acquisition of a huge amount of data that can and should be used for improving processes and decision-making. Utilizing this data requires appropriate data processing and data analysis schemes. In the processing and analysis stage, most often, a broad spectrum of data mining algorithms is ap

Abstract:

In the present fast-paced world of business in a highly competitive marketplace, the focus on increasing the efficiency of business processes seems to be a reasonable challenge. For this reason in order to optimize production costs, there is an increasing trend toward maximising the use of the operational capabilities of the equipment – technological line components – with the prevention of failure events and their consequences in the form of costly repairs or replacements. A condition-based maintenance (CBM) approach allows to globally monitor, maintain and control operation of the whole comp

Abstract:

Purpose The purpose of this paper is to contribute to the theoretical reflection on learning study as a research approach. The focus is on description and reflection on the methodology of learning study as paedeutic research. This research is for, not on, teachers, i.e. research into problems and challenges faced by teachers in their professional practice. Learning study as paedeutic research is about the content and processes of formation/Bildung in relation to specific learning objects. Its focus is on subject-specific ways of knowing as well as how such knowing is enabled through teaching.

In this paper were experimentally determined properties of four different types of stones and stone aggregates and they were compared to each other with respect to their influence on wear of working parts of machines for preparation and deposition of stones on roads. Rocks, the building stones are obtained from, consist of various types of minerals, namely of physically and chemically homogeneous rocks created within the Earths crust. Here are considered four, most important types of building stones: limestone, dolomite marble, calcite-dolomite marble and andesite. They are being exploited fro

Abstract:

The performance of slide bearings in forestry machines and equipment is largely determined by the load-carrying capacity and antifriction qualities that depend on the bearing capacity of the sleeve (insert) material, the design rigidity and the nature of the forces during operation. As a result, the bearing materials undergo cyclic changes in the state of the sleeve material, as well as the elements that provide reinforcing, heat-conducting and anti-wear functions. The paper shows the results of research on the stress-strain behavior of anisotropic composite materials in the structures of wood

Public space is increasingly recognised to be central to spatial discourse of cities. A city’s urbanism is displayed in public spaces, representing a myriad of complex socio-cultural, economic and democratic practices of everyday life. In cities of the Global South, especially those with nascent democracies, different values attached to a space by various actors – both material and symbolic – frame the contestation, making the physical space a normative instrument for contestation. Tundikhel, once believed to be the largest open space in Asia, is an important part of Kathmandu’s urbanism, whic

It should be highlighted that the improvement of systems or machinery is a permanent decision making process, i.e. the process that has its start but has no end. It means that it is impossible for absolutely ideal system or machine to appear. The improvement of machinery rests upon

Abstract:

Traditional fault diagnosis methods of DC (direct current) motors require establishing accurate mathematical models, effective state and parameter estimations, and appropriate statistical decision-making methods. However, these preconditions considerably limit traditional motor fault diagnosis methods. To address this issue, a new mechanical fault diagnosis method was proposed. Firstly, the vibration signals of motors were collected by the designed acquisition system. Subsequently, variational mode decomposition (VMD) was adopted to decompose the signal into a series of intrinsic mode function

In the design of architecture, machinery, and electronic circuits, many materials and equations have been prepared and utilized for each part involved and for each design requirement. We generally regard knowledge, such as a design formula, as restrained conditional knowledge and develop a system to find solutions by the reduction method. The system is capable of handling values and numerical equations, retrieval of design material, and searching for solutions, making it effective for programming design calculation. Therefore, the system is superior to conventional design systems written in FO
