Form und ZeitHöfler, Carolin 19 September 2011 (has links)
Seitdem der Computer in den 1990er Jahren zur omnipräsenten Infrastruktur der zeitgenössischen Architekturproduktion wurde, fand die technologische Seite der digitalen Formgenerierung große Aufmerksamkeit, wohingegen die Interpretation von Raum als kontinuierliche Oberfläche eher unterbelichtet blieb. Die relativ einfache und schnelle Erzeugung von Freiformflächen durch entsprechende 3D-Software, die Geschwindigkeit, mit der Computer ständig variable Morphologien und Familien von nicht euklidischen Formen berechnen können, hat zu der Annahme verleitet, die weichen Flächen und räumlichen Konfigurationen seien wissenschaftlich unausweichlich und technologisch prädestiniert. Die Wahl dieser Formen beruht aber weder allein auf einer technologischen Vorgabe noch auf einem rein stilistischen Konzept. Mithilfe neuer Technologien werden zeitbasierte Raummodelle erprobt, die sich vom traditionellen Konzept des kartesischen Raumes als Koordinatensystem abheben. Die Untersuchung und Interpretation dieser Raumvorstellungen und ihrer Semantik bilden den Kernpunkt der vorliegenden Arbeit. Dem rhetorisch formulierten Anspruch nach waren die computergenerierten Formen das Produkt einer Nullsetzung. So stark dieser Anspruch bis heute aufrechterhalten wird, so wenig lässt sich verbergen, dass diese scheinbar neue generierte Bildwelt auf zahlreichen Vorbildern aufbaut. Es sind vor allem die Programme und Projekte gegen eine als monoton und dogmatisch empfundene Architekturmoderne, die auf die Gestalter digitaler Raummodelle eingewirkt haben. Zur Rekonstruktion der Rezeptionslinien werden drei Raumbegriffe bestimmt, die ihre Prägung in der experimentellen Architektur der Nachkriegsmoderne fanden: der endlose Raum, die vernetzte Struktur und die schräge Fläche. Mit diesen Begriffen werden Kontinuitäten und Diskontinuitäten in der Entwicklung der experimentellen Architektur herausgestellt, und die computerbasierten Raumkonzepte einer kritischen Betrachtung unterzogen. / Since the computer became omnipresent infrastructure of contemporary architectural production in the 1990s, a great deal of attention has been given to the technological side of the digital form generation, whereas the interpretation of space as a continuous surface has tended to remain underexposed. The relatively easy and fast generation of free-form surfaces using appropriate 3D software, the speed with which computers are able to calculate constantly variable morphologies and families of non-Euclidean shapes, has led to the assumption that soft surfaces and spatial configurations are scientifically inevitable and technologically predestined. However, the choice of these shapes is neither based on a technological specification nor on a purely stylistic concept. With the help of new technologies, time-based space models are tested, which contrast with the traditional concept of Cartesian space as a coordinate system. The investigation and interpretation of these spatial ideas and their semantics form the core of this work. If the rhetorically worded claim were to be believed, the computer-generated shapes are the product of muting. However strongly this claim has been maintained until now, it is nonetheless hardly possible to conceal that this apparently new generated graphic world is in fact built upon numerous examples. Above all, it is the programs and projects against a modern architecture found to be monotonous and dogmatic, which have influenced the designers of digital spatial models. To reconstruct the reception lines, three spatial terms are defined, which found their style in the experimental architecture of the post-war modern age: the endless space, networked structure and inclined surface. With the help of these terms, continuities and discontinuities are brought out in the development of experimental architecture, and the computer-based spatial concepts are subjected to critical examination.

Här och nu : en undersökning om närvaro och motivation / Here and now : about presence and motivationJarl, Agnes January 2019 (has links)
Att elever inte alltid kommer i tid till en lektion är nog ett problem som de flestagymnasieskolor i Sverige har. Utifrån sen ankomst som bakgrund och diskussion med eleverom skolans riktlinjer kring sen ankomst, utvecklades intresset för att utforska eleversmotivation för skolnärvaro. Jag har bett elever i årskurs två på gymnasiet att kommunicerasina erfarenheter om motivation, närvaro och sen ankomst. Genom a/r/tography somförhållningssätt har syftet varit att undersöka min egen ämnesdidaktik för att kunna skapaförutsättningar kring elevers motivation och närvaro i bildämnet och i klassrummet. Detövergripande syftet med undersökningen är att undersöka gymnasieelevers motivation ibildämnet samt att medvetandegöra eleven genom skapande, om sin egen plats och närvarorent fysiskt och psykiskt. Studien utgår från frågeställningen, Hur formulerar och gestaltargymnasieeleverna sin upplevelse kring motivation och närvaro. Vad synliggörs när jagundersöker skolfrånvaro genom den bildpedagogiska praktiken tillsammans med eleverna?I undersökningen består en del av empirin av kakelplattor i lera skapat av eleverna därde kommunicerar erfarenheter och tankar kring motivation och närvaro. Resultatet visar hurelevernas motivation för skolarbetet ofta ligger utanför den specifika pedagogiska praktiken.Många anger CSN som motivation, då deras studiestöd vid frånvaro riskerar att dras in. Andratänker mer långsiktigt på närvaron som nödvändig för goda skolresultat och framtidaarbete. Även skolan som en plats att träffa vänner är motiverande för skolnärvaro. Genomeget skapande undersöker även jag dessa frågor parallellt med eleverna i denna undersökningoch som en medskapare av bilder. Elevernas kakel har satts samman till en vägg likaså harmina kakelplattor bildat en vägg. Utöver att dessa kakelplattor analyseras enskilt iuppsatsen, så visas också den praktiska och konstnärliga undersökningens resultat påKonstfacks vårutställning.Mitt arbete och mina slutsatser pekar mot att eleverna också motiveras av att arbetatillsammans, med en utställning som mål. I analysen har jag kommit fram till och förståttderas tidigare erfarenheter om skolan som en plats där motivation att komma till skolan i rätttid präglas av förväntningar av omgivning lika mycket som motivationen av att vilja ha enljus framtid och en utbildning för sin egen skull.

Urban Intensification in Metropolitan Khartoum : Influential Factors, Benefits and ApplicabilityElghazali, Burhan January 2006 (has links)
This dissertation explores the theoretical and methodological implications involved in the policy framework needed to intensify urban residential areas in a developing country. Metropolitan Khartoum, Sudan, has been chosen as a case study. The aim of the study is to further our understanding of the implications of transforming a sprawling city form to an intensified form. The objectives are: to identify the factors that have shaped Sudanese urban form in general and Metropolitan Khartoum in specific; to identify the policies that can intensify the urban residential neighborhoods in Metropolitan Khartoum; and, to influence both the demand and requisite housing needs for this intensified form. This research is qualitative in its nature: the complexity of the study problematic required the adoption of a constructivist paradigm as the fundamental set of beliefs. Inductive arguments are used in conjunction with a wide range of methods, including detailed descriptions of Sudan and metropolitan Khartoum, with special emphasis on how local environment, urban challenges, policy, legislation and practices affect the study problematic. The theoretical premises of intensification are reviewed along with development issues, urban infrastructure challenges and opportunities in developing countries and local acceptability of intensification. The different forces that can shape urban forms have been described and the suitability of metropolitan Khartoum, with different general urban intensification policies and practices and of urban management tools in large African cities has been investigated. The outcome of the study provides detail for a discussion of results that work to explain some of the cause and effect of urban sprawl in Metropolitan Khartoum. It also suggests possible change in both policy and regulation to induce successful city reform towards intensification. / QC 20110121

On the Structure of the Domain of a Symmetric Jump-type Dirichlet FormSchilling, René L., Uemura, Toshihiro 16 June 2014 (has links) (PDF)
We characterize the structure of the domain of a pure jump-type Dirichlet form which is given by a Beurling–Deny formula. In particular, we obtain su cient conditions in terms of the jumping kernel guaranteeing that the test functions are a core for the Dirichlet form and that the form is a Silverstein extension. As an application we show that for recurrent Dirichlet forms the extended Dirichlet space can be interpreted in a natural way as a homogeneous Dirichlet space. For reflected Dirichlet spaces this leads to a simple purely analytic proof that the active reflected Dirichlet space (in the sense of Chen, Fukushima and Kuwae) coincides with the extended active reflected Dirichlet space. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Wh-constructions and the division of labour between syntax and the interfacesΒλάχος, Χρήστος 01 February 2013 (has links)
The minimalist approach to natural human language argues that the syntax of a language L maps a certain structure to a certain form at PF and to a certain meaning at LF. With the above in mind, the ideal perhaps scenario, in terms of transparency, would be that the mapping between form and meaning would be one to one. In other words, there is as much form as there is meaning. This would further imply that the mapping between form and meaning is symmetric. The present thesis studies some aspects of the form and meaning of two kinds of wh-constructions in Modern Greek, i.e., questions and sluicing, and shows that
the relevant mapping may not necessarily be one to one. With respect to questions, it is argued that the same form may correspond to more than one meaning. As regards sluicing, it is proposed that there is less form than meaning. On the face of the previous, the argument will be as follows. Syntax generates form, and restricts part of meaning, while additional aspects of meaning are facilitated by PF, regarding wh-questions, and LF, concerning sluicing. Finally, since PF contributes to meaning, LF sees PF, and vice versa. / Το μινιμαλιστικό πλαίσο προσέγγισης της φυσικής ανθρώπινης γλώσσας υποστηρίζει ότι η σύνταξη μιας γλώσσας Γ αντιστοιχεί μια ορισμένη μορφή με μια ορισμένη δομή στην ΦΔ, και με μία ορισμένη σημασία στην ΛΔ. Με αυτό ως δεδομένο, το ιδεατό ίσως σενάριο, όσον αφορά στην διαφάνεια, θα ήταν ότι η αντιστοίχιση μεταξή μορφής και σημασίας είναι ένα προς ένα. Με άλλα λόγια, υπάρχει τόση μορφή όση και σημασία. Κάτι τέτοιο θα υπονοούσε επίσης ότι η αντιστοίχιση μορφής-σημασίας είναι συμμετρική. Η παρούσα διατριβή μελετά ορισμένες πτυχές δομών ερώτησης μερικής αγνοίας, και δομών εκκένωσης, στα Νέα Ελληνικά, και δείχνει ότι η εν λόγω αντιστοίχιση δεν είναι απαραίτητα ένα προς ένα. Όσον αφορά στις δομές ερώτησης μερικής αγνοίας, υποστηρίζεται ότι η ίδια μορφή μπορεί να σχετίζεται με περισσότερες από μια σημασίες. Σχετικά με τις δομές εκκένωσης, προτείνεται ότι φέρουν λιγότερη μορφή απο σημασία. Με βάση τα παραπάνω, το επιχείρημα θα έχει ως εξής. Η σύνταξη παράγει μορφή, και περιορίζει μέρος της σημασίας, ενώ ένα άλλο μέρος της σημασίας εισάγεται από την ΦΔ, όσον αφορά στις ερωτήσεις μερικής αγνοίας, και την ΛΔ, σχετικά με τις δομές εκκένωσης. Τέλος, αφού η ΦΔ συνεισφέρει στην σημασία, τότε η ΛΔ δομή βλέπει την ΦΔ, και αντιστρόφως.

Confiabilidade estrutural de pontes laminadas protendidas de madeira / Structural reliability of stress laminated timber bridgesMalton Lindquist 11 December 2006 (has links)
O conceito de tabuleiros laminados de madeira protendidos transversalmente foi usado inicialmente no Canadá na década de 70. Desde então, foi largamente utilizado em um número crescente de países. No Brasil, esse sistema foi utilizado pela primeira vez com a construção da ponte sobre o rio Monjolinho, na região metropolitana de São Carlos, estado de São Paulo. A importância deste sistema estrutural requer um maior conhecimento de sua segurança estrutural. Assim, este trabalho teve como objetivo estudar a confiabilidade estrutural de pontes protendidas de madeira, com enfoque na resistência da estrutura à flexão transversal. As pontes foram dimensionadas através de três métodos, o de Ritter, Eurocode e OTB, sendo os dois primeiros conhecidos na literatura e o último baseado na solicitação encontrada através de um software de análise de placas ortotrópicas, OTB. Para obter índices de confiabilidade foi utilizado o método FORM, e o método de Monte Carlo para simular a utilização das fórmulas de obtenção de resistências características sugeridas na NBR 7190:1997 e DIN 68364. Os resultados indicaram que o sistema estrutural é confiável dentro do modo de falha estudado. / Stress laminated timber bridges were first built in Canadá in the seventies. Since then, this kind of structure has been increasingly used in many countries. In Brazil, this structure was first designed in the bridge over Monjolinho stream, in São Carlos, São Paulo state. The importance of this system requires a better knowledge about its structural safety. Therefore, the aim of this work is to research the structural reliability of stress laminated timber bridges, with special focus on transversal bending strength. Bridges were designed by three methods: Ritter, Eurocode and OTB. Ritter and Eurocode are well known design methods. OTB is based on an ortotropic timber bridges analysis software. In order to obtain reliability results, FORM method was used. Monte Carlo method was also considered to simulate characteristic values outputs by brazilian code, NBR 7190:1997, and german code, DIN 68364. Results indicate that the structure os reliable for the limit state studied.
