Comparison of the most popular operating systems in terms of functionalities

The main purpose of research is comparison of the following modern operating systems: Windows 10, Windows 11, MacOS Catalina and Linux Ubuntu 20.04 LTS. An analysis was made in terms of functionalities and time needed to perform basic activities. The systems were selected on the basis on performed popularity analysis, by using StatCounter [1] statistic. To study each operating system it was necessary to create two test stands corresponding to the requirements of the systems. Conducted research were divided on two sections. In the first one, analysis of the possessed functionalities, assessment of the advancement and ease of using them was performed. In the second section, examination was carried out to compare the operating system in terms of the time of performing specific activities

From analogy-making to modelling : the history of analog computing as a modelling technology

Today, modern computers are based on digital technology. However, during the decades after 1940, digital computers were complemented by the separate technology of analog computing. But what was analog computing, what were its merits, and who were its users? This thesis investigates the conceptual and technological history of analog computing. As a concept, analog computing represents the entwinement of a complex pre-history of meanings, including calculation, modelling, continuity and analogy. These themes are not only landmarks of analog's etymology, but also represent the blend of practices, ways of thinking, and social ties that together comprise an 'analog culture'. The first half of this thesis identifies how the history of this technology can be understood in terms of the two parallel themes of calculation and modelling. Structuring the history around these themes demonstrates that technologies associated with modelling have less representation in the historiography. Basing the investigation around modelling applications, the thesis investigates the formation of analog culture. The second half of this thesis applies the themes of modelling and information generation to understand analog use in context. Through looking at examples of analog use in academic research, oil reservoir modelling, aeronautical design, and meteorology, the thesis explores why certain communities used analog and considers the relationship between analog and digital in these contexts. This study demonstrates that analog modelling is an example of information generation rather than information processing. Rather than focusing on the categories of analog and digital, it is argued that future historical scholarship in this field should give greater prominence to the more general theme of modelling

The ingenuity of common workmen: and the invention of the computer

Since World War II, state support for scientific research has been assumed crucial to technological and economic progress. Governments accordingly spent tremendous sums to that end. Nothing epitomizes the alleged fruits of that involvement better than the electronic digital computer. The first such computer has been widely reputed to be the ENIAC, financed by the U.S. Army for the war but finished afterwards. Vastly improved computers followed, initially paid for in good share by the Federal Government of the United States, but with the private sector then dominating, both in development and use, and computers are of major significance.;Despite the supposed success of public-supported science, evidence is that computers would have evolved much the same without it but at less expense. Indeed, the foundations of modern computer theory and technology were articulated before World War II, both as a tool of applied mathematics and for information processing, and the computer was itself on the cusp of reality. Contrary to popular understanding, the ENIAC actually represented a movement backwards and a dead end.;Rather, modern computation derived more directly, for example, from the prewar work of John Vincent Atanasoff and Clifford Berry, a physics professor and graduate student, respectively, at Iowa State College (now University) in Ames, Iowa. They built the Atanasoff Berry Computer (ABC), which, although special purpose and inexpensive, heralded the efficient and elegant design of modern computers. Moreover, while no one foresaw commercialization of computers based on the ungainly and costly ENIAC, the commercial possibilities of the ABC were immediately evident, although unrealized due to war. Evidence indicates, furthermore, that the private sector was willing and able to develop computers beyond the ABC and could have done so more effectively than government, to the most sophisticated machines.;A full and inclusive history of computers suggests that Adam Smith, the eighteenth century Scottish philosopher, had it right. He believed that minimal and aloof government best served society, and that the inherent genius of citizens was itself enough to ensure the general prosperity

Simulation FX: Cinema and the R&D Complex

This study looks at the ongoing development of tools and practices used to animate nonlinear physical phenomena, such as the crash of ocean waves or the movement of human hair, in the visual effect and animation industries. These tools and practices are developed in a nexus between public funding, research universities, the film industry, and various other sectors, such as aerospace and meteorology. This study investigates how technological development became integrated with film production, and in turn how epistemic paradigms were shared between the film industry, scientific research institutions and other industries. At the heart of these animation tools and practices, and the networks of institutions that developed them, is a way of thinking that seeks to make use of unpredictable nonlinear complexity by shaping it toward specific applications. I observe this in the way animation and visual effect studios seek the realistic appearance of nonlinear natural movement through simulation, while also implementing technologies and practices to direct the look of these simulations. I also observe this in a variety of related examples, from the way the concept of research and development unites science and application, to the way management science promotes hands off approaches that preserve the unpredictable nature of creative work. My methods consist of charting the circulation of ideas, technologies, moving images and people through contact zones such as the computer science special interest group ACM SIGGRAPH, using archival research of trade communications, scholarly publications and conference proceedings, as well as interviews with industry workers

Moving in a man\u27s world: three qualitative case studies illustrate how women can survive in male-dominated work environments

The purpose of this study was to analyze the factors influencing women\u27s decisions to enter male-dominated work environments, specifically the fields of academia, law, and Computer Sciences; In order to encourage more women to pursue nontraditional careers, it is necessary to determine the types of support and environments required for women to succeed in these areas. Therefore, qualitative, interpretive research within a feminist theoretical framework was used to assess the impact of family background, educational opportunities, and cultural expectations on the respondents\u27 career choices. How the respondents negotiated the imaginary line between their personal and private lives, and how they handled the discriminatory roadblocks in their workplaces were also analyzed. Triangulation was used for data collection and analysis. Specific tools utilized included: in-depth interviews (quotations), direct observations (field notes), and written materials (documentation). Member checks were used to verify the data collected;Results from the interpretation of the data revealed that glass ceilings and gender discrimination still exist within these patriarchal work environments. Despite these obstacles, the women who participated in this study were able to succeed in their nontraditional careers by re-inventing their lives, defying gendered cultural expectations, and becoming indispensable in their fields through specialization. The implications for this research are far-reaching. Male-dominated work environments will become more equitable when sex-role stereotypes are minimalized in familial and educational environments, gender communication patterns are revised, and the corporate culture is restructured to recognize women\u27s unique qualities and contributions

Users, systems, and technology in high-end audio

Thesis (Ph. D. in History, Anthropology, and Science, Technology and Society (HASTS))--Massachusetts Institute of Technology, Program in Science, Technology and Society, 2009.Page 414 blank.Includes bibliographical references (p. 401-413).This is a story about technology, users, and music. It is about an approach to the design, manipulation, and arrangement of technologies in small-scale systems to achieve particular aesthetic goals - goals that are at once subjective and contingent. These goals emerge from enthusiasm for technology, for system-building, and for music among members of a community of users, and the promise of the emotional rewards derived from these elements in combination. It is a story about how enthusiasm and passion become practice, and how particular technologies, system-building activities, listening, debating, innovating, and interacting form that practice. Using both historical and ethnographic research methods, including fieldwork and oral history interviews, this dissertation is focused on how and why user communities mobilize around particular technologies and socio-technical systems. In particular, it concerns how users' aesthetic sensibilities and enthusiasm for technology can shape both technologies themselves and the processes of technological innovation. These issues are explored through a study of the small but enthusiastic high-end audio community in the United States. These users express needs, desires, and aesthetic motivations towards technology that set them apart from mainstream consumers, but also reveal important and under-recognized aspects of human relationships with technology more broadly. Covering the emergence and growth of high-end audio from the early 1970s to 2000, I trace some of the major technology transitions during this period and their associated social elements, including the shift from vacuum tube to solid-state electronics in the 1970s, and from analog vinyl records to digital compact discs in the 1980s. I show how this community came to understand technology, science, and their own social behavior through powerful emotional and aesthetic responses to music and the technologies used to reproduce music in the home. I further show how focusing on technology's users can recast assumptions about the ingredients and conditions necessary to foster technological innovation.by Kieran Downes.Ph.D.in History, Anthropology, and Science, Technology and Society (HAST
