The study provides the analysis of the planning documentation developed for the city in the post-Soviet period. In particular, it elaborates on the currently enforced Strategy of Economic and Social Development of St. Petersburg-2030 (2014) and the City General Plan (2005), discussing the aspects of their development and implementation, as well as complex interrelation. Thereby, peculiarities of the spatial development of the St. Petersburg agglomeration are also investigated, elaborating on the state policy on agglomerations, historic development of St. Petersburg and relations with the Leningrad Region, governance and imbalances of the St. Petersburg spatial development, including proposed development scenarios. Consequently, the study employs a highly indicative case of the Lomonosov town municipal unit aiming to illustrate the practical implementation of administrative, territorial and strategic policies in a given context within a system of the state planning adopted in St. Petersburg, in particular, taking into consideration recently proclaimed necessity for the transition to a polycentric city model following an innovative scenario for the socioeconomic and spatial development. In particular, Lomonosov (Oranienbaum) is explored egarding its current socio-economic situation and development scenarios: industrial site and cultural tourism. The Oranienbaum museum and nature-reserve is also thoroughly assessed with regard to its cultural tourism potential. Finally, the urban environment of Lomonosov (Oranienbaum) is comprehensively scrutinized in terms of its historic development, residential housing typology, UNESCO World Heritage preservation and local urban heritage. In conclusion, the data on Lomonosov present in the St. Petersburg strategic and territorial planning documents is provided.}, subject = {Lomonossow}, language = {en} } @phdthesis{Hollberg, author = {Hollberg, Alexander}, title = {A parametric method for building design optimization based on Life Cycle Assessment}, doi = {10.25643/bauhaus-universitaet.3800}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20180928-38000}, school = {Bauhaus-Universit{\"a}t Weimar}, pages = {262}, abstract = {The building sector is responsible for a large share of human environmental impacts. Architects and planners are the key players for reducing the environmental impacts of buildings, as they define them to a large extent. Life Cycle Assessment (LCA) allows for the holistic environmental analysis of a building. However, it is currently not employed to improve the environmental performance of buildings during the design process, although the potential for optimization is greatest there. One main reason is the lack of an adequate means of applying LCA in the architectural design process. As such, the main objective of this thesis is to develop a method for environmental building design optimization that is applicable in the design process. The key concept proposed in this thesis is to combine LCA with parametric design, because it proved to have a high potential for design optimization. The research approach includes the analysis of the characteristics of LCA for buildings and the architectural design stages to identify the research gap, the establishment of a requirement catalogue, the development of a method based on a digital, parametric model, and an evaluation of the method. An analysis of currently available approaches for LCA of buildings indicates that they are either holistic but very complex or simple but not holistic. Furthermore, none of them provide the opportunity for optimization in the architectural design process, which is the main research gap. The requirements derived from the analysis have been summarized in the form of a catalogue. This catalogue can be used to evaluate both existing approaches and potential methods developed in the future. In this thesis, it served as guideline for the development of the parametric method - Parametric Life Cycle Assessment (PLCA). The unique main feature of PLCA is that embodied and operational environmental impact are calculated together. In combination with the self-contained workflow of the method, this provides the basis for holistic, time-efficient environmental design optimization. The application of PLCA to three examples indicated that all established mandatory requirements are met. In all cases, environmental impact could be significantly reduced. In comparison to conventional approaches, PLCA was shown to be much more time-efficient. PLCA allows architects to focus on their main task of designing the building, and finally makes LCA practically useful as one of several criteria for design optimization. With PLCA, the building design can be time-efficiently optimized from the beginning of the most influential early design stages, which has not been possible until now. PLCA provides a good starting point for further research. In the future, it could be extended by integrating the social and economic aspects of sustainability.}, subject = {Bauentwurf}, language = {en} } @phdthesis{MartinezSoto, author = {Martinez Soto, Aner}, title = {Analyse und Erweiterung von bestehenden Prognosemodellen zur Bestimmung des Endenergiebedarfs im Wohnungssektor}, doi = {10.25643/bauhaus-universitaet.3225}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170607-32251}, school = {Bauhaus-Universit{\"a}t Weimar}, pages = {291}, abstract = {Die wachsende Notwendigkeit zur Energieeinsparung hat in verschiedenen L{\"a}ndern zur Entwicklung von Prognosemodellen zur Bestimmung des Energiebedarfs im Wohnungssektor gef{\"u}hrt.

This strategy combines a conceptual framework developed around the notion of 'centrality' and 'urban semiotics' as a method of qualitative enquiry in order to comprehend complex spatial arrangements as significant constituents of cultural geographies. In this sense, this study problematizes current tendencies such as spatial fragmentation and challenges the argument that contemporary urban ensembles in Latin America are either homogenized within globalization trends or illegible entities with no structural coherence. Bogot{\´a} is addressed as an instrumental case study to redraw generalizations developed from different methodological frameworks about the configuration process of spatial structures and their significance within the Latin American geography. Thus the study questions how urban centrality has evolved as an essential socio-cultural phenomenon and in this manner decodes the messages transmitted by main spatial arrangements. As a first step, the study discusses the construction of spatial meaning and its structural interpretation. In addition, the concept of centrality is examined in depth and an urban centrality typology is introduced to enable the analysis of spatial structures in socio-cultural terms. These contents are followed by the discussion of the existing approaches to the topic and their limitations. Subsequently, this research reconstructs the configuration of Bogot{\´a}'s spatial structure which is decoded in the last chapter. The study concludes that the highly fragmented and uneven condition of urban space in Latin America can be read. The case study of Bogot{\´a} substantiates that there is a code that paradoxically provides spatial cohesiveness within unstable socio-spatial hierarchies. Such a spatial code is deciphered through the reading of Bogot{\´a}'s spatial structure whose super-centre denotes 'the sacralisation of authoritarianism'. This is a 'structural meaning' related to a specific or intrinsic logic of spatial concentration that is useful for the further discussion of socio-spatial patterns and the meanings of Latin American cities.

In anticipation of these directives, an association of informal waste reclaimers group called Uswag Calajunan Livelihood Association, Inc. (UCLA) was formed in May 2009. One option identified was the waste-to-energy activity through the production of fuel briquettes. With the availability of raw materials in the area, what was lacking then was an appropriate technology that would cater to their needs. This study, therefore, presented the case of UCLA on how socio-economic and technical aspects was integrated for the development and improvement of a briquetting technology needed in the production of quality briquettes as part of their income generating activities. A non-experimental posttest only design was utilized for the collection of descriptive information. Descriptions and discussions were also made on the enhancement of the briquetting machine from the first hand-press molder developed until the finalized design was attained. Results revealed that the improved briquetting technology withstood the wear and tear of operation showing a significant (P<0.01) increase on the production rate (220 pcs/hr; 4 kg/hr) and bulk density (444.83 kg/m3) of briquettes produced. The quality of cylindrical briquettes produced in terms of bulk density, heating value (15.13 MJ/kg), moisture (6.2\%), N and S closely met or has met the requirements of DIN 51731. Based on the operating expenses, the briquettes may be marked-up to Php0.25/pc (USD0.006) or Php15.00/kg (USD0.34) for profit generation. The potential daily earnings of Php130.00 (USD2.95) to Php288.56 (USD6.56) generated in producing briquettes are higher when compared to the majority of waste reclaimers' daily income of Php124.00 (USD2.82). The high positive response (93\%) on the usability of briquettes and the willingness of the respondents (81\%) to buy them when sold in the market indicates its promising potential as fuel in the nearby communities. Results of briquette production citing the case of UCLA could be considered as potential source of income given the social, technical, economic and environmental feasibility of the experiment. This method of utilizing wastes in an urban setting of a developing country with similar socio-economic and physical set-ups may also be recommended for testing or replication.}, subject = {Biotechnologie}, language = {en} } @phdthesis{Hahn, author = {Hahn, S{\"o}nke}, title = {Bunker—TV, TV—Bunker: Heterotope Mechanismen am Beispiel von Schutzbauwerken und (Fernseh-)Serien}, doi = {10.25643/bauhaus-universitaet.3711}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20171205-37116}, school = {Bauhaus-Universit{\"a}t Weimar}, pages = {376 + 256}, abstract = {Die vorliegende Dissertation widmet sich anhand eines kurios anmutenden, aber auf einer Metaebene fruchtbaren Vergleichs von Schutzbauwerken und Fernsehserien historischen und aktuellen Mechanismen menschlichen Denkens und Handelns. Als theoretische Basis dieser Abhandlung fungiert die Heterotopie - ein Konzept des franz{\"o}sischen Philosophen Michel Foucault. Die Heterotopie ist ein inflation{\"a}r gebrauchtes, oft nur oberfl{\"a}chlich betrachtetes Theorem. Das Konzept wird hier nun mit Blick auf das Gesamtwerk Foucaults en d{\´e}tail untersucht sowie um korrelierende Ans{\"a}tze (Aug{\´e}, Lefebvre, Soja ...) erg{\"a}nzt. Aus dieser Betrachtung l{\"a}sst sich ein {\"u}ber Foucault hinausgehender, analytisch nutzbarer Katalog ableiten. Verk{\"u}rzt wird die Heterotopie folgendermaßen bestimmt: Neben der Definition der Heterotopie als Raum des Anderen, als (gesellschaftskritischer) Gegenraum kann sie dem wie auch immer bestimmten Normalraum unterstellt sein. Die Heterotopie ist m{\"o}glicherweise eine bauliche Manifestation schwarz-weißen Denkens, von Ausgrenzung und sichtbarer Unsichtbarkeit, sie wird zur Realisation wie auch immer definierter Ideale oder Stereotypen. Die Heterotopie ist allerdings auch als ein (hybrides) Dazwischen denkbar, welches sich als katalytischer Raum, im dialektischen Sinne als Ort der Synthese {\"a}ußert. Es k{\"o}nnte als Niemandsland oder als Phase (im Leben) charakterisiert werden. Analog zum letzten Beispiel l{\"a}sst sich die Heterotopie als progressiv-seriell beschreiben. Ihre stagnierend bis variierende Serialit{\"a}t kann sich im Betreten identischer R{\"a}ume {\"a}ußern - mal als verl{\"a}sslich oder erm{\"u}dend empfunden. Nicht nur die einem entsprechenden Raum entgegengebrachten Konnotationen sind vielf{\"a}ltig bis ambivalent, die Heterotopie ist neben real-r{\"a}umlicher auch virtueller Fasson: Betonmauer finden bisweilen eine Entsprechung im einfachen Harmoniefernsehen. Einander heterotop gegen{\"u}berstehenden R{\"a}umen wird etwa mit der Figur Walter White in der komplexen Fernsehserie "Breaking Bad" entsprochen - ist er doch hin und her gerissen zwischen seiner biederen, aber geliebten Familie einerseits und der abstoßend gewaltt{\"a}tigen, aber extrovertierende Potentiale bergenden Drogenproduktion andererseits. Die sogenannte Leihk{\"o}rperschaft bzw. die Immersion lassen sich zur Beschreibung verschiedener Heterotopie-Erfahrungen nutzen. Dieses Eintauchen/Betreten wird hier als Rezeptionsph{\"a}nomen zwischen sensomotorischer Illusion und inhaltlich-narrativem Sog, zw. Fixierung des K{\"o}rpers und Einbezug desselbigen definiert. Die beiden Untersuchungsfelder werden jeweils f{\"u}r sich historisch und theoretisch umrissen. Zum noch jungen Feld serieller Theorie/der Definition narrativer Typen (im TV bzw. dem Qualit{\"a}tsfernsehen) wird ein einf{\"u}hrender {\"U}berblick geboten. Die praktischen Arbeiten setzen sich {\"a}sthetisch, narrativ und inhaltlich mit der Heterotopie auseinander: In "Habitat" und "Habitat 2" werden serielle Konzepte audiovisuell (u. a. als Fulldome-Version) erprobt. Dabei wird insbesondere das Heterotope im Konzept "Autor" untersucht - der Autor als distinkte und gleichsam konfliktbehaftete, in zahlreiche Subjekte zerlegte Figur. "Habitat 3" ist ein Publikationskonzept, welches mit etablierten (heterotopen) Strukturen des Sammelbands bricht und zugleich die heterotopen Facetten des fiktionalen Fernsehens simuliert.

This thesis aims to contribute to our understanding on how people experience data and what role representational modality plays in the process of perception and interpretation. This research is grounded in phenomenology - I align my theoretical exploration to ideas and concepts from philosophical phenomenology, while also respecting the essence of a phenomenological approach in the choice and application of methods. Alongside offering a rich description of people's experience of data representation, the key contributions I claim transcend four areas: theory, methods, design, and empirical findings. From a theoretical perspective, besides describing a phenomenology of human-data relations, I define, for the first time, multisensory data representation and establish a design space for the study of this class of representation. In relation to methodologies, I describe and deploy two methods to investigate different aspects of data experience. I blend the Repertory Grid technique with a focus group session and show how this adaption can be used to elicit rich design relevant insight. I also introduce the Elicitation Interview technique as a method for gathering detailed and precise accounts of human experience. Furthermore, I describe for the first time, how this technique can be used to elicit accounts of experience with data. My contribution to design relates to the creation of a series of bespoke data-driven artefacts, as well as describing an approach to design that I call Design Probes, which allows researchers to focus their enquiry on specific design features. To answer the research questions I set out in this thesis, I report on a series of empirical studies that used the aforementioned methods. The findings of these studies show, for instance, how certain representational modalities cause us to have heightened awareness of our body, some are more difficult to interpret than others, some rely heavily on instinct and each of them solicit us to reference external events during the process of interpretation. I conclude that a phenomenology of human-data relations show how representational modality affects the way we experience data, it also shows how this experience unfolds and it offers insight into particular moments such as the formation of meaning.}, subject = {Design}, language = {en} } @phdthesis{Wenzel, author = {Wenzel, Jakob}, title = {Design and Analysis of Cryptographic Algorithms for Authentication}, doi = {10.25643/bauhaus-universitaet.3714}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20171208-37140}, school = {Bauhaus-Universit{\"a}t Weimar}, abstract = {During the previous decades, the upcoming demand for security in the digital world, e.g., the Internet, lead to numerous groundbreaking research topics in the field of cryptography. This thesis focuses on the design and analysis of cryptographic primitives and schemes to be used for authentication of data and communication endpoints, i.e., users. It is structured into three parts, where we present the first freely scalable multi-block-length block-cipher-based compression function (Counter-bDM) in the first part. The presented design is accompanied by a thorough security analysis regarding its preimage and collision security. The second and major part is devoted to password hashing. It is motivated by the large amount of leaked password during the last years and our discovery of side-channel attacks on scrypt - the first modern password scrambler that allowed to parameterize the amount of memory required to compute a password hash. After summarizing which properties we expect from a modern password scrambler, we (1) describe a cache-timing attack on scrypt based on its password-dependent memory-access pattern and (2) outline an additional attack vector - garbage-collector attacks - that exploits optimization which may disregard to overwrite the internally used memory. Based on our observations, we introduce Catena - the first memory-demanding password-scrambling framework that allows a password-independent memory-access pattern for resistance to the aforementioned attacks. Catena was submitted to the Password Hashing Competition (PHC) and, after two years of rigorous analysis, ended up as a finalist gaining special recognition for its agile framework approach and side-channel resistance. We provide six instances of Catena suitable for a variety of applications. We close the second part of this thesis with an overview of modern password scramblers regarding their functional, security, and general properties; supported by a brief analysis of their resistance to garbage-collector attacks. The third part of this thesis is dedicated to the integrity (authenticity of data) of nonce-based authenticated encryption schemes (NAE). We introduce the so-called j-IV-Collision Attack, allowing to obtain an upper bound for an adversary that is provided with a first successful forgery and tries to efficiently compute j additional forgeries for a particular NAE scheme (in short: reforgeability). Additionally, we introduce the corresponding security notion j-INT-CTXT and provide a comparative analysis (regarding j-INT-CTXT security) of the third-round submission to the CAESAR competition and the four classical and widely used NAE schemes CWC, CCM, EAX, and GCM.}, subject = {Kryptologie}, language = {en} } @phdthesis{Staeudel, author = {St{\"a}udel, J{\"u}rgen}, title = {Development, Implementation and Operation of Integrated Sanitation Systems Based on Material-Flows - Integrated Sanitation in the City of Darkhan, Mongolia - A Practicable Example}, doi = {10.25643/bauhaus-universitaet.3179}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170512-31794}, school = {Bauhaus-Universit{\"a}t Weimar}, abstract = {The world society faces a huge challenge to implement the human right of "access to sanitation".

This dissertation examines the possibility to enhance "access to sanitation" for people who are living in areas with underdeveloped water and wastewater infrastructure systems. The idea hereby is to follow an integrated approach for sanitation, which allows for a mutual completion of existing infrastructure with resource-based sanitation systems. The notion "integrated sanitation system (iSaS)" is defined in this work and guiding principles for iSaS are formulated. Further on the implementation of iSaS is assessed at the example of a case study in the city of Darkhan in Mongolia. More than half of Mongolia's population live in settlements where yurts (tents of Nomadic people) are predominant. In these settlements (or "ger areas") sanitation systems are not existent and the hygienic situation is precarious. An iSaS has been developed for the ger areas in Darkhan and tested over more than two years. Further on a software-based model has been developed with the goal to describe and assess different variations of the iSaS. The results of the assessment of material-flows, monetary-flows and communication-flows within the iSaS are presented in this dissertation. The iSaS model is adaptable and transferable to the socio-economic conditions in other regions and climate zones.}, subject = {Abwasser}, language = {en} } @phdthesis{Oroz, author = {Oroz, Gonzalo}, title = {Die Wege der Ungleichheit.
