The following study traces the production and history of the talismanic scroll as a medium through a Fatimid, Ayyubid, and Mamluk historical periods. My dissertation understands the protocol of manufacturing and utilizing talismanic scrolls. The dissertation is a study of the Qur'an, prayers and illustrations of these talismanic works. I begin by investigating a theory of the occult the medieval primary sources of the Neo-platonic tenth century Ikhwān al-Safa and al-Bunī (d.1225). I establish that talismans are generally categorized as science (`ilm). Next, a dynastic spotlight of talismanic scrolls creates a chronological framework for the dissertation. The Fatimid talismanic scrolls and the Ayyubid pilgrimage scrolls are both block-printed and are placed within the larger conceptual framework of pilgrimage and devotion. The two unpublished Mamluk scrolls from Dar Al-Athar Al-Islamiyyah are long beautiful handwritten scrolls that provide a perspective on how the occult is part of the daily life of the practitioner in the medieval Islamic culture. Through an in depth analysis of the written word and images, I establish that textually and visually there is a template for the creation of these sophisticated scrolls. Lastly, I discuss the efficacy of these scrolls, I use theories of linguistic anthropology and return to the Islamic primary sources to establish that there is a language of the occult and there are people that practiced the occult. The word of God and the Qur'ān empower the scrolls I studied. As for the people who practiced the occult, I turn to the tenth century Ibn al-Nadim and Ibn al-Khaldun (d.1406), the people of the occult are understood. Yet, keeping in mind, that there is always a tension with the theologians that condoned practices of Islamic magic. / History of Art and Architecture

This creative project will culminate in a show of twenty-five pieces of metalwork, both wearable and sculptural, using as source material the rich tradition the floral imagery found in Islamic arts. Specifically the pieces will be based on the art of the Persian Gulf area. sources will be floral images as expressed in architectural elements, fabric, tiles, and other related arts or crafts. / Department of Art

This thesis deals with the problem of technical product configuration: Connect individual components conforming to a component catalogue in order to meet a given objective while respecting certain constraints. Solving such configuration problems is one of the major success stories of applied AI research: In industrial environments they support the configuration of complex products and, compared to manual processes, help to reduce error rates and increase throughput. Practical applications are nowadays ubiquitous and range from configurable cars to the configuration of telephone communication switching units. In the classical definition of a configuration problem the number of components to be used is fixed while in practice, however, the number of components needed is often not easily stated beforehand. Existing knowledge representation (KR) formalisms expressive enough to deal with this dynamic aspect of configuration require that explicit bounds on all generated components are given as well as extensive knowledge about the underlying solving algorithms. To date there is still a lack of high-level KR tools being able to cope with these demands. In this work we present LoCo, a fragment of classical first order logic that has been carefully tailored for expressing technical product configuration problems. The core feature of LoCo is that the number of components used in configurations does not have to be finitely bounded explicitly, but instead is bounded implicitly through the axioms. We identify configurations with models of the logic; hence, configuration finding becomes model finding. LoCo serves as a high-level representation language which allows the modelling of general configuration problems in an intuitive and declarative way without the need of having knowledge about underlying solving algorithms; in fact, the specification gets automatically translated into low-level executable code. LoCo allows translations into different target languages. We present the language, related algorithms and complexity results as well as a prototypical implementation via answer-set programming.

What do we see when we look at writing? In addition to the verbal messages conveyed by the written words, visual dimensions of script are powerful tools that hold semantic value. This dissertation focuses on one such visual element—the arrangement of written words into geometric shapes or patterns in the context of medieval Islamicate societies (1100–1250 AD)—to uncover its meanings. The dissertation offers a primary case study of the Kitāb al-diryāq (Book of Antidotes, 595 AH/1199 AD, BnF arabe 2964), an illuminated and illustrated manuscript with a variety of geometric patterns created using Arabic script. By examining a broad range of materials (scientific manuscripts, magical objects, and architectural decoration) across Late Antiquity and the medieval period, this heuristic study argues that the arrangement of script in geometric patterns was a vital medium of visualizing knowledge and transmitting knowledge—the form not only carrying cultural meanings but also shaping the reception of verbal messages. Magic is one form of knowledge that is particularly fruitful for examining the function of the geometric script patterns in general, and of the Kitāb al-diryāq in particular. This study traces the contexts in which the geometric script patterns appear, the cultural practices associated with them, and the medieval worldviews in which the patterns circulated. In considering these factors, the study argues that the combination of shape and script is embedded with knowledge that reflects the medieval scientific, magical, and popular imagination. / Graduate / 2023-06-23

Yes / The complex formation of Islamic Geometric Patterns (IGP) is one of the distinctive features in Islamic art and architecture. Many have attempted to reproduce these patterns in digital form, using various pattern generation techniques, in 2D. Shape grammars are an e ective pattern generation method, providing good aesthetic results. In this pa- per we describe a novel approach in generating 3D IGP using the shape grammar method. The particular emphasis here is to generate the motifs (repeated units with the pattern) in 3D using parameterization. These can then be manipulated within the 3D space to construct architec- tural structures. In this work we have developed two distinctive Shape Grammars in 3D namely Parameterized Shape Grammar (PSG) and Auto-Parameterized Shape Grammar (APSG). Here the PSG generates the motifs and the APSG enables construction of the structures using the generated motifs. Both grammars are practically implemented as a 3D modelling tool within Autodesk Maya. The parameterization within each grammar is the key to generate both Islamic geometric motifs and Islamic geometric motif-based structures.

Biofouling is the undesired biofilm formation on surfaces at a liquid interface that interferes with the affected substrate’s function. It is a ubiquitous problem in many engineered systems in industry. Biofouling causes contamination, essential damage to materials, and impedances to crucial industrial processes. These adverse effects lead to health hazards, gross increase in energy consumption, and significant decrease in overall productivity, all of which result in higher operational costs and environmentally destructive consequences. Interest in discovering effective alternatives to conventional antimicrobial agents has gained momentum. Current anti-biofouling strategies have significant disadvantages, such as the generation of toxic by-products, indiscriminate corrosion of surrounding materials and the environment, and promotion of resistance development. Alternative methods of controlling biofouling are in high demand because present-day solutions are far from sustainable. Plant secondary metabolites are promising candidates as novel biocides because they are (i) highly effective in killing microbes while being non-toxic to humans at antimicrobially active concentrations, and (ii) safer and non-damaging to the natural environment. Herein, antimicrobial efficacies of five plant-derived compounds were assessed against various species of planktonic bacteria as well as biofilms at various maturity stages. Allyl isothiocyanate (AIT) and cinnamaldehyde (CNAD) displayed the greatest inhibitory effects against all planktonic species tested. The minimum inhibitory concentration is defined as the lowest concentration of a substance that inhibits visible microbial growth, and the MBC is defined as the lowest concentration at which 99.9% of the population is killed. AIT yielded MICs of 156.25 mg/L and MBCs of 156.25 to 312.5 mg/L, and CNAD yielded MICs of 78.125 to 156.25 mg/L and MBCs of 78.125 to 312.5 mg/L. Furthermore, 312.5 mg/L AIT and 625 mg/L CNAD successfully reduced > 80% of biofilm adhesion as compared to negative controls. AIT and CNAD were therefore further evaluated extensively. Hindered by their volatile nature and immiscibility, plant secondary metabolites typically do not reach their maximum antimicrobial capacity due to low bioavailability. Thus, they would benefit from being protected and delivered in nano-sized carriers. In this study, mesoporous silica nanoparticles (MSNs) were evaluated as carriers for AIT and CNAD delivery. In one, employment of MSNs as carriers doubled the antibacterial efficacy of free form AIT and increased kill rate of free form CNAD by six times. Furthermore, free form AIT caused ~70% of 60 day-old biofilm to detach, whereas AIT-loaded MSNs essentially removed all of the biofilm. As for CNAD, its free form had no significant effect, whereas CNAD-loaded MSNs caused ~80% reduction in biofilm biomass. MSNs were further engineered to incorporate lactose pore caps to achieve specific, on-command delivery. These MSNs were designed to respond to external stimuli intelligently, with gatekeepers that degrade only in the vicinity of certain target bacteria that are able to metabolise lactose. Capped AIT-loaded MSNs reduced bacterial viability by ~85% as compared to the negative control, while capped CNAD-loaded versions reduced viability by ~40%. This stimuli-triggered MSN delivery technology would be more sustainable than current methods because resistance development would be lowered, and the delivery vehicles could be recycled and reused. Herein, the complete AIT- or CNAD-loaded, lactose-capped MSNs delivery complex proved to be an effective and environmentally conscientious system for killing unwanted bacteria.

This thesis is a comprehensive re-examination of Maritime Southeast Asia's (or the Nusantara's) Islamic conversion history between the late thirteenth and early seventeenth centuries. Traditionally, academia has attributed this event to Muslim traders and/or Sufis from either India and/or the Middle East. During the late twentieth century, however, a number of scholars began to consider the possibility of Chinese Muslim involvement. The resulting discussions focused on a re-evaluation of Javanese history in the context of attempts to re-conceptualise pre-modern Nusantara trade (considered the catalyst for Islamisation) as fundamentally orientated towards Southern China, where Muslims played a significant commercial role from the seventh through to the early fifteenth centuries. Despite the intrinsic merits of these efforts, however, they have all been limited by an overwhelming focus on Java and a tendency to examine the relevant issues over only a very narrow time span. This thesis seeks to rectify these problems. First, it will evaluate the validity of the new commercial framework over a much longer period – from the rise of Śrīvijaya in the seventh century CE to the establishment of the early seventeenth-century European trade monopolies. This longue dureé view will provide a much stronger basis for both conclusively re-orientating pre-modern Nusantaran trade towards China and also positing it as the catalyst for conversion, with Chinese Muslims at its heart. Second, the thesis will look beyond Java to examine the conversion histories of several other important Nusantara locations (Samudera-Pasai, Melaka and Brunei), as accessed through early written texts (indigenous, European and Chinese) and archaeology. The thesis then, and thirdly, couples this examination with a consideration of the Islamic influences which came to bear on the Nusantara’s early intellectual and architectural expressions of Islam. Ultimately, by taking this broad chronological, geographical and cultural approach, the thesis aims to more reliably assess the possibility that Chinese Muslims influenced the Nusantara’s initial Islamisation process.

To what extent does China's experience of economic reform since 1989 compel a reconsideration of the ontological foundations of contemporary capitalist development? China's political economy remains characterized by a unique and resilient political structure (the Chinese Communist Party) that penetrates both 'private' (market) and 'public' (state) organizations. The conceptual rootedness of contemporary theories of comparative and international political economy in a distinctly Western historical experience of capitalist development hinders their ability to understand Chinese capitalism on its own terms—as historically, culturally, and globally embedded. To generate greater analytic traction in understanding China's otherwise paradoxical constellation of actors and dynamics, I argue that contemporary capitalism should be studied as a set of mechanisms for managing and exploiting socio-economic uncertainty, rather than according to the binary logics of state regulation and market competition. These mechanisms can be conceptualized as an overarching risk environment. On this basis, I trace how the cognitive frames, social institutions, and relational networks that emerged within the 'socialist market economy' in China's post-Tiananmen financial system have placed the Chinese Communist Party at the nexus of the state and the market. I argue that specific ideas emerged about how to manage the flow of capital, playing a significant role in underpinning expectations of financial growth and stability. During this period the financial system underpinned the CCP's capacity to both manage and exploit socio-economic uncertainty through the path of reform, forming a central explanatory factor in a developmental trajectory marked by a trifecta of rapid economic growth, macroeconomic stability, and deepening socio-economic imbalances. Rather than viewing the path of financial reform in China solely in terms of 'partial' or 'failed' free- market reform, it thus becomes possible to cast China's development in a new light as the product of a more concerted vision of how the financial system would enable a mode of economic development that combined the drive for capital accumulation with the distinctive socio-political circumstances of post-1989 China.
