    These days, transportation is seen as a basic need since so much labour can only be performed with the presence and assistance of some kind of transportation. The development of new roadways is crucial to the whole community of a city because of the widening usage of highways nowadays. Investing in new roadway pavement may be very beneficial for a nation, but the price in terms of environmental and energy sustainability is just too high. Reclaimed asphalt pavement (RAP) has been used as a cheaper alternative to fresh asphalt pavement in civil engineering projects. RAP's performance degrades with time owing to the fact that it is made from recycled, hardened asphalt pavement

    Towards an Archaeology of the Contemporary Past

    Archaeology, defined as the study of material culture, extends from the first preserved human artefacts up to the present day, and in recent years the ‘Archaeology of the Present’ has become a particular focus of research. On one hand are the conservationists seeking to preserve significant materials and structures of recent decades in the face of redevelopment and abandonment. On the other are those inspired by social theory who see in the contemporary world the opportunity to explore aspects of material culture in new and revealing ways, and perhaps above all the central question of the extent to which material culture — be it in the form of objects or buildings — actively defines the human experience. Victor Buchli's An Archaeology of Socialism takes as its subject a twentieth-century building — the Narkofim Communal House in Moscow — and seeks to understand it in terms of domestic life and changing policies of the Soviet state during the 70 or so years since its construction. Thus Buchli's study not only concerns the meaning of material culture in a modern context, but focuses specifically on the household — or more accurately on a series of households within a single Russian apartment block. A particular interest attaches to the way in which the building was planned to encourage communal living, during a pre-Stalinist phase when the State sought to intervene directly in domestic life through architectural design and the manipulation of material culture. Subsequent political changes brought a revision of modes of living within the Narkofim apartment block, as the residents adjusted and responded to changing political and social pressures and demands. The significance of Buchli's study goes far beyond the confines of Soviet-era Moscow or indeed the archaeology of the modern world. He questions the role and potential danger of social and archaeological theory of the totalizing kind: a natural response perhaps to the experience of the Narkofim Communal House as an exercise in Soviet social engineering. He poses fascinating questions about the relation between individual households and the state ideology, and he emphasizes the role of material culture studies in reaching an understanding of these processes. In the brief essay that opens this Review Feature, Victor Buchli outlines the principal aims and conclusions of An Archaeology of Socialism. The diversity of issues that the book generates is revealed in the series of reviews which follows, touching in particular upon the ways in which routines of daily life — archaeologically visible, perhaps, through the analysis of domestic space — relate to structures of authority in society as a whole

    Bottom-up construction of ontologies

    Get PDF
    Presents a particular way of building ontologies that proceeds in a bottom-up fashion. Concepts are defined in a way that mirrors the way their instances are composed out of smaller objects. The smaller objects themselves may also be modeled as being composed. Bottom-up ontologies are flexible through the use of implicit and, hence, parsimonious part-whole and subconcept-superconcept relations. The bottom-up method complements current practice, where, as a rule, ontologies are built top-down. The design method is illustrated by an example involving ontologies of pure substances at several levels of detail. It is not claimed that bottom-up construction is a generally valid recipe; indeed, such recipes are deemed uninformative or impossible. Rather, the approach is intended to enrich the ontology developer's toolki

    Homesteading the noosphere: The ethics of owning biological information

    Get PDF
    The idea of homesteading can be extended to the realm of biological entities, to the ownership of information wherein organisms perform artifactual functions as a result of human development. Can the information of biological entities be ethically “homesteaded”: should humans (or businesses) have ownership rights over this information from the basis of mere development and possession, as in Locke’s theory of private property? I offer three non-consequentialist arguments against such homesteading: the information makeup of biological entities is not commonly owned, and thus is not available for homesteading; the value of the individual biological entity extends to the information whereby it is constituted, and includes inalienable rights of an entity over itself and its information; and use of life as an information artifact makes an organism an unending means to an end rather than an end itself. I conclude that the information space of biological entities is not open for homesteading, not liable to private ownership, and should not be available for perpetual exploitation

    Incorporating Agile with MDA Case Study: Online Polling System

    Full text link
    Nowadays agile software development is used in greater extend but for small organizations only, whereas MDA is suitable for large organizations but yet not standardized. In this paper the pros and cons of Model Driven Architecture (MDA) and Extreme programming have been discussed. As both of them have some limitations and cannot be used in both large scale and small scale organizations a new architecture has been proposed. In this model it is tried to opt the advantages and important values to overcome the limitations of both the software development procedures. In support to the proposed architecture the implementation of it on Online Polling System has been discussed and all the phases of software development have been explained.Comment: 14 pages,1 Figure,1 Tabl

    IDEF5 Ontology Description Capture Method: Concept Paper

    Get PDF
    The results of research towards an ontology capture method referred to as IDEF5 are presented. Viewed simply as the study of what exists in a domain, ontology is an activity that can be understood to be at work across the full range of human inquiry prompted by the persistent effort to understand the world in which it has found itself - and which it has helped to shape. In the contest of information management, ontology is the task of extracting the structure of a given engineering, manufacturing, business, or logistical domain and storing it in an usable representational medium. A key to effective integration is a system ontology that can be accessed and modified across domains and which captures common features of the overall system relevant to the goals of the disparate domains. If the focus is on information integration, then the strongest motivation for ontology comes from the need to support data sharing and function interoperability. In the correct architecture, an enterprise ontology base would allow th e construction of an integrated environment in which legacy systems appear to be open architecture integrated resources. If the focus is on system/software development, then support for the rapid acquisition of reliable systems is perhaps the strongest motivation for ontology. Finally, ontological analysis was demonstrated to be an effective first step in the construction of robust knowledge based systems

    Space is the machine, part four: theoretical syntheses

    Get PDF
    Part IV of the book, ‘Theoretical Syntheses’, begins to draw together some of the questions raised in Part I, the regularities shown in Part II and the laws proposed in Part III, to suggest how the two central problems in architectural theory, namely the form-function problem and the form-meaning problem, can be reconceptualised. Chapter 10, ‘Space is the machine’, reviews the form-function theory in architecture and attempts to establish a pathology of its formulation: how it came to be set up in such a way that it could not be solved. It then proposes how the configuration paradigm permits a reformulation, through which we can not only make sense of the relation between form and function in buildings, but also we can make sense of how and why buildings, in a powerful sense are ‘social objects’ and in fact play a powerful role in the realisation and sustaining of human society. Finally, in Chapter 11, ‘The reasoning art’, the notion of configuration is applied to the study of what architects do, that is, design. Previous models of the design process are reviewed, and it is shown that without knowledge of configuration and the concept of the non-discursive, we cannot understand the internalities of the design process. A new knowledge-based model of design is proposed, with configuration at its centre. It is argued from this that because design is a configurational process, and because it is the characteristic of configuration that local changes make global differences, design is necessarily a top down process. This does not mean that it cannot be analysed, or supported by research. It shows however that only configurationally biased knowledge can really support the design Introduction Space is the machine | Bill Hillier Space Syntax Introduction process, and this, essentially, is theoretical knowledge. It follows from this that attempts to support designers by building methods and systems for bottom up construction of designs must eventually fail as explanatory systems. They can serve to create specific architectural identities, but not to advance general architectural understanding. In pursuing an analytic rather than a normative theory of architecture, the book might be thought by some to have pretensions to make the art of architecture into a science. This is not what is intended. One effect of a better scientific understanding of architecture is to show that although architecture as a phenomenon is capable of considerable scientific understanding, this does not mean that as a practice architecture is not an art. On the contrary, it shows quite clearly why it is an art and what the nature and limits of that art are. Architecture is an art because, although in key respects its forms can be analysed and understood by scientific means, its forms can only be prescribed by scientific means in a very restricted sense. Architecture is law governed but it is not determinate. What is governed by the laws is not the form of individual buildings but the field of possibility within which the choice of form is made. This means that the impact of these laws on the passage from problem statement to solution is not direct but indirect. It lies deep in the spatial and physical forms of buildings, in their genotypes, not their phenotypes. Architecture is therefore not part art, and part science, in the sense that it has both technical and aesthetic aspects, but is both art and science in the sense that it requires both the processes of abstraction by which we know science and the processes of concretion by which we know art. The architect as scientist and as theorist seeks to establish the laws of the spatial and formal materials with which the architect as artist then composes. The greater scientific content of architecture over art is simply a function of the far greater complexity of the raw materials of space and form, and their far greater reverberations for other aspects of life, than any materials that an artist uses. It is the fact that the architect designs with the spatial stuff of living that builds the science of architecture into the art of architecture. It may seem curious to argue that the quest for a scientific understanding of architecture does not lead to the conclusion that architecture is a science, but nevertheless it is the case. In the last analysis, architectural theory is a matter of understanding architecture as a system of possibilities, and how these are restricted by laws which link this system of possibilities to the spatial potentialities of human life. At this level, and perhaps only at this level, architecture is analogous to language. Language is often naïvely conceptualised as a set of words and meanings, set out in a dictionary, and syntactic rules by which they may be combined into meaningful sentences, set out in grammars. This is not what language is, and the laws that govern language are not of this kind. This can be seen from the simple fact that if we take the words of the dictionary and combine them in grammatically correct sentences, virtually all are utterly meaningless and do not count as legitimate sentences. The structures of language are the laws which restrict the combinatorial possibilities of words, and through these restrictions construct the sayable and the meaningful. The laws of language do not therefore tell us what to say, but prescribe the structure and limits of the sayable. It is within these limits that we use language as the prime means to our individuality and creativity. In this sense architecture does resemble language. The laws of the field of architecture do not tell designers what to do. By restricting and structuring the field of combinatorial possibility, they prescribe the limits within which architecture is possible. As with language, what is left from this restrictive structuring is rich beyond imagination. Even so, without these laws buildings would not be human products, any more than meaningless but syntactically correct concatenations of words are human sentences. The case for a theoretical understanding of architecture then rests eventually not on aspiration to philosophical or scientific status, but on the nature of architecture itself. The foundational proposition of the book is that architecture is an inherently theoretical subject. The very act of building raises issues about the relations of the form of the material world and the way in which we live in it which (as any archaeologist knows who has tried to puzzle out a culture from material remains) are unavoidably both philosophical and scientific. Architecture is the most everyday, the most enveloping, the largest and the most culturally determined human artefact. The act of building implies the transmission of cultural conventions answering these questions through custom and habit. Architecture is their rendering explicit, and their transmutation into a realm of innovation and, at its best, of art. In a sense, architecture is abstract thought applied to building, even therefore in a sense theory applied to building. This is why, in the end, architecture must have analytic theories

    Development and implantation of a Thesaurus of Manufacturing Engineering terms

    Present work shows the teaching-learning experience developed in the Department of Manufacturing Engineering of the University of Malaga. This experience is based on the need to generate a specific glossary of manufacturing engineering terms to be used as a study guide by the students. Eventually, it was decided to make a Thesaurus that would be aimed at a teaching activity. Also, it would take part in the educational innovation project PIE 13-025 of the University of Malaga, within the biennium 2013/2015. The first step consisted of the design of Thesaurus pattern, taking into account the kind of information that it was necessary include in it. Afterward, this pattern would be place on the Virtual Campus and the student would have to complete the information required. Finally, the results obtained in the different applications of this activity would be analyzed and evaluated.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
