    Some Cosmological Roots of Modern Architecture5-17en [543.58 kB - PDF]EPA-02446-00003-0010

    Abstract: This paper investigates the links between some oriental cosmologies and modern architecture, stemming from major non-Western religions, such as Buddhism, Islam and Judaism as well as from Einstein’s theories. It analyses both the direct impact of these concepts, influencing modernism at a theoretical level, and their indirect impact through historic non-Western architecture, mainly Buddhist and Islamic. While modernist theoreticians and architects frequently emphasised functional and technical priorities of modernism, I argue that modernism was far less rational than it is commonly thought, and that it was substantially influenced by non-Western thought, particularly in its early period. This paper considers two main innovations of modernism resulting from oriental concepts of void: (1) the flat and undecorated façade, the avoidance of traditional ‘façade-discourse’, (2) the promotion of space as the main objective of architecture. The impact of Buddhist, Islamic, Judaic and the Einstenian cosmologies on modernism are considered.

    Abstract: The Mental Rotation Test (MRT) is one of the tests to survey the spatial ability. In this article we make an attempt to measure the spatial abilities of the students of wood industrial engineering and industrial design engineering of the Simonyi Károly Faculty of Engineering, Wood Sciences and Applied Arts (SKF for short) of the University of West Hungary and compare the results with the architects students of the Ybl Miklós Faculty of Architecture and Civil Engineering of the Szent István University. The paper aims to compare the results with respect to the scores and mainly the improvement based on new examination aspects. The article concludes that the small differences in the students’ developments of spatial ability in the two institutions can be caused by the difference in Descriptive Geometry courses.

    Abstract: In spite of the fact the scene of food production is the rural territory; we are witnessing more and more unusual endeavours for farming in cities, additionally in megalopolises. There are numerous researches on the theme, and the new interest in the local cultivation of fruit and vegetable in cities is becoming an earnest factor in urban life in Western Europe, in the USA, and in the Developing World. At the Aristotle University of Thessaloniki, AUTh two professors of architecture managed a course for MSc students of architecture and horticulture, with the intend of designing forms of urban agriculture on a fallow area in Thessaloniki, and considering the crisis situation in Greek. With analysing the proposals of “The Thessaloniki project - Red and Green” parallel with various realized urban agriculture projects I emphasise the force and necessity of the generation of a community

    Abstract: The aim of the ongoing research is (i) to develop a new biodegradation landfill technique so that the landfill gas production could be controlled and the utilisation of the landfill gas could economically be optimized, (ii) to plan the energy utilisation of the landfill including individual and combined solutions (solar, wind, geothermal energy, energy storage using methanol etc.). [1, 2, 3] After summarizing the previous measurements made on the ongoing research, the first results of the oedometer tests are presented. The compression curves were determined, the measured data are evaluated by two simple models, the parameters are identified, the reliability of the parameters is tested. The simple models make possible the separation of the three major components of the settlement: the immediate settlement, the creep settlement and the primary consolidation settlement. The degradation induced strains were not considered since the tests were short term. Using these components, three different oedometric moduli are defined. The identified parameters are presented and compared with the parameters previously identified from some CPTu dissipation test data, and with the parameters measured by some recent seismic tests. The parameters are used to estimate the settlement of the landfill.

    “Can the Tower be Retained”65-78en [753.89 kB - PDF]EPA-02446-00003-0050

    Abstract: This paper focuses on the analysis of two towers of an industrial plant exhibiting extreme deflection during service loads under heavy wind conditions. The towers are 90 m and 35 m in height, respectively and are interconnected with structural steel operating platforms. The nuts have flown off at some bolted joints in the interconnecting steel structure due to high stress induced by deflections. The deflections measured at the structural steel towers had nearly twice the value permitted by the respective standard in the case of the 90 m high tower and approached the value permitted by the standard in the case of the 35 m high tower. The herein detailed complex study – covering the strength analysis of the towers, the analysis of wind effects, and the review of the foundations – has been elaborated in order to determine the causes and consequences of the experienced deflections at the plant as well as to conclude the eventual actions to be taken. The primary consideration for the conduction of the tests and analyses the determination of the eventual actions to be taken was to retain the towers and not to have them demolished.
