A Study of Maintenance-Related Education in Swedish Engineering Programs

Engineers of today require a holistic understanding of the lifecycle of products and processes, from conceptualization to operations. Maintenance and reliability are areas receiving increased attention due to the contribution to sustainable industry practices. The related literature describes ways to strengthen the education with respect to curricula and teaching, but studies on the extent and content of maintenance-related education in engineering programs are lacking. The purpose of this study is to describe the maintenance-related education content in Swedish engineering programs. The main objects of study are the curricula and courses of engineering programs in Sweden. In total, 123 Bachelor of Engineering and 119 Master of Engineering programs were studied, as well as 36 maintenance-related courses. It was found that 12% of the engineering programs include one or more maintenance-related course, either mandatory or elective. On the Master of Engineering level, only 4% of the programs include mandatory maintenance-related courses. The corresponding number for Bachelor of Engineering programs is 15%. The courses are typically of 6–7.5 credits, but as low as under one credit worth of maintenance-related content is seen, as well as two specialized programs offering up to 60 credits. Of the 36 courses, 20 have a distinct maintenance focus, 2 are degree thesis courses, and 2 are within reliability engineering, while the rest have a focus in other areas. The lack of maintenance-related education makes future engineers less prepared to make good decisions and judgments that might affect the operational phase of the product or system.

Restoration circuits for low power reduce swing of 6T and 8T SRAM cell with improved read and write margins

<span>This article clarifies about the variables that influence the static noise margin (SNM) of a static random-access memory. Track down the improved stability of proposed 8T SRAM cell which is superior to conventional 6T SRAM cell utilizing Swing Restored circuit with voltages Q and QB bar are peruse and Compose activity. This SRAM cell strategy on the circuit or engineering level is needed to improve read static noise margin (RSNM), write static noise margin (WSNM) and hold static noise margin (HSNM). This article relative investigation of conventional 6T, standard 8T and proposed 8T SRAM cells with improved stability and static noise margin is finished for 180 nm CMOS innovation. This paper is coordinated as follows: Introduction in area 1, The 6T SRAM cell are portrayed in segment 2. In area 3, proposed 8T SRAM cell is portrayed. In area 4, standard 8T SRAM cell. Segment 5 incorporates the simulation and results which give examination of different boundaries of 6T and 8T SRAM cells and segment 6 conclusions.</span>

Improving the technological support of dairy cattle breeding

The paper discusses the issues of providing the population of the Russian Federation with milk and dairy products, increasing milk production, and implementing investment projects in the industry. It is noted that the technological and technical support, as well as improving the systems of keeping, feeding and milking animals play an important role in solving problems of increasing the efficiency of dairy farming. Particular attention is paid to the introduction of innovative technologies and modern machinery at dairy farms and facilities, including equipment fitted with digital systems for collecting information about the state of animals, milk yield, milking parameters and other indicators, as well as robots. Milking installations provided by the system of machines are designed for milking cows in stalls, milking parlors, as well as in maternity wards. According to their engineering level, they must ensure the fulfillment of the physiological milk let-down requirements, the productive longevity of animals, etc. The developed artificial intelligence system allows planning the efficiency of feeding and monitoring the main processes at a dairy farm. Feed is of paramount importance in the prime cost of raw milk. The cost of feed affects the profitability of production. Spectrometers, including pocket ones, can be used for feed analysis. Improvement of technologies in dairy production will help to increase the competitiveness of the industry.

What is Scientific Progress?

The article examines the understanding of scientific progress by scientists and representatives of the philosophy of science, in particular, W. Whewell, E. Mach, M. Weber, logical positivism. It is noted that until the middle of the twentieth century, scientists and philosophers were convinced that science is constantly progressing, developing more and more complete and accurate knowledge of the world. Only in the second half of the twentieth century K. Popper and T. Kuhn questioned this belief, proposing their conceptions of the development of sci­ence. However, the belief in the progressive nature of the development of sci­ence received a new justification in a three layer model of the structure of sci­ence, which added an engineering level to the theoretical and empirical levels. By the end of the twentieth century it was realized that the experimental science of modern times initially saw its main task in the improvement of technology, the search for truth was 0nly a means of solving its main social task. In the sec­ond half of the twentieth century technoscience has fulfilled its historical mission, creating a technical basis for the formation of a consumer society. Ap­parently, its development is over. In place of science, occupied with the improve­ment of technology, there are sciences, the subject of which is man and his im­provement.

A Semantic Mixed Reality Framework for Shared Cultural Experiences Ecosystems

This paper presents SemMR, a semantic framework for modelling interactions between human and non-human entities and managing reusable and optimized cultural experiences, towards a shared cultural experience ecosystem that might seamlessly accommodate mixed reality experiences. The SemMR framework synthesizes and integrates interaction data into semantically rich reusable structures and facilitates the interaction between different types of entities in a symbiotic way, within a large, virtual, and fully experiential open world, promoting experience sharing at the user level, as well as data/application interoperability and low-effort implementation at the software engineering level. The proposed semantic framework introduces methods for low-effort implementation and the deployment of open and reusable cultural content, applications, and tools, around the concept of cultural experience as a semantic trajectory or simply, experience as a trajectory (eX-trajectory). The methods facilitate the collection and analysis of data regarding the behaviour of users and their interaction with other users and the environment, towards optimizing eX-trajectories via reconfiguration. The SemMR framework supports the synthesis, enhancement, and recommendation of highly complex reconfigurable eX-trajectories, while using semantically integrated disparate and heterogeneous related data. Overall, this work aims to semantically manage interactions and experiences through the eX-trajectory concept, towards delivering enriched cultural experiences.
