Throughout history, the spread of microorganisms has caused much damage including infectious diseases and deaths. Ever since humans realized the impact of bacteria especially on population health many efforts have been done to combat the spread of pathogens. Textiles, as suitable environments for the growth of microorganisms are one of the major sources of epidemics. Therefore, producing antibacterial textiles can lessen the chances of transmission of microorganisms. In spite of effective protection antibacterial textiles offer, lack of comfort can result in less interest in the products from the users. The aim of this project is to use valve-jet printing as a resource-efficient finishing method to produce antibacterial textiles and measure its effect on comfort properties. As a natural, non-toxic, and biodegradable antibacterial agent, chitosan was chosen to be printed on cotton fabric. An ink with 0.5 w/v% concentration of chitosan dissolved in 1.5v/v% acetic acid was prepared and printed on cotton fabric through ChromoJet printer. The fabric was cured at 150°C for 1 minute to stabilize the chitosan on cotton. Three types of printed fabrics were produced with different number of printing passes. The samples were characterized by various methods to investigate the performance of printed chitosan ink on the antibacterial and comfort properties of the cotton fabric. Results indicate a successful printing of chitosan ink on cotton fabric through valve-jet printing method. Results further showed that multiple printing passes of chitosan ink on cotton fabric can result in higher antibacterial activity. However, with excessive increase of chitosan, the fabric compromises the hand feel and softness. Results also showed an increase in air permeability with the increment in the amount of chitosan on the cotton fabric, whereas capillary rise decreased with the increase of chitosan amount. Contact angle measurement and hydrostatic pressure test showed that between the printed and not-printed samples no big difference was observed in terms of hydrophilicity. The result of the thesis is of great importance as they introduce new printing process for the fabrication of antibacterial textile with comfort properties for various applications.

This dissertation addresses the fundamental problem of how to build computing systems for the nanoscale. With CMOS reaching fundamental limits, emerging nanomaterials such as semiconductor nanowires, carbon nanotubes, graphene etc. have been proposed as promising alternatives. However, nanoelectronics research has largely focused on a `device-first' mindset without adequately addressing system-level capabilities, challenges for integration and scalable assembly. In this dissertation, we propose to develop an integrated nano-fabric, (broadly defined as nanostructures/devices in conjunction with paradigms for assembly, inter-connection and circuit styles), as opposed to approaches that focus on MOSFET replacement devices as the ultimate goal. In the `fabric-centric' mindset, design choices at individual levels are made compatible with the fabric as a whole and minimize challenges for nanomanufacturing while achieving system-level benefits vs. scaled CMOS. We present semiconductor nanowire based nano-fabrics incorporating these fabric-centric principles called NASICs and N3ASICs and discuss how we have taken them from initial design to experimental prototype. Manufacturing challenges are mitigated through careful design choices at multiple levels of abstraction. Regular fabrics with limited customization mitigate overlay alignment requirements. Cross-nanowire FET devices and interconnect are assembled together as part of the uniform regular fabric without the need for arbitrary fine-grain interconnection at the nanoscale, routing or device sizing. Unconventional circuit styles are devised that are compatible with regular fabric layouts and eliminate the requirement for using complementary devices. Core fabric concepts are introduced and validated. Detailed analyses on device-circuit co-design and optimization, cascading, noise and parameter variation are presented. Benchmarking of nanowire processor designs vs. equivalent scaled 16nm CMOS shows up to 22X area, 30X power benefits at comparable performance, and with overlay precision that is achievable with present-day technology. Building on the extensive manufacturing-friendly fabric framework, we present recent experimental efforts and key milestones that have been attained towards realizing a proof-of-concept prototype at dimensions of 30nm and below.

Smart contracts are software systems that monitor and control the execution of legal contracts to ensure compliance with the contracts' terms and conditions. They often exploit Internet-of-Things technologies to support their monitoring functions, and blockchain technology to ensure the integrity of their data. Ethereum and business blockchain platforms, such as Hyperledger Fabric, are among the most popular choices for smart contract development. However, there is a substantial gap in the knowledge of smart contracts between developers and legal experts. Symboleo is a formal specification language for legal contracts that was introduced to address this issue. Symboleo specifications directly encode legal concepts such as parties, obligations, and powers. This thesis proposes a tool-supported method for translating Symboleo specifications into smart contracts. Its contributions include extensions to the existing Symboleo IDE, the implementation of the ontology and semantics of Symboleo into a reusable library, and the Symboleo2SC tool that generates Hyperledger Fabric code exploiting this library. Symboleo2SC was evaluated with three sample contracts. Experimentation with Symboleo2SC shows that legal contract specifications in Symboleo can be fully converted to smart contracts for monitoring purposes. Moreover, Symboleo2SC helps simplify the smart contract development process, saves development effort, and helps reduce risks of coding errors.

<p> Sedimentary structures, textures and fabric were studied in detail in eight turbidite greywacke beds from the Cloridorme Formation (Middle Ordovician), Gaspe, Quebec. The beds are exposed on the wave-cut platform near Grande Vallee and were traced for about two miles along the strike (276 degrees), which is parallel to the average current direction (274 degrees) as indicated by sole mark directions. </p> <p> The beds under study show the following systematic downcurrent changes along the strike from east to west: (i) Sole mark types show the following changes: (1) tool marks such as grooves, prod marks and isolated flute marks, to (2) longitudinal ridges, longitudinal ridges with overlapping flute, closely spaced flutes, to (3) poorly developed, shallow longitudinal ridges with occasional cuspate crossing bars, to (4) smooth bottom with occasional grooves. (ii) There is an increase in variance of sole mark directions without a large change in the mean direction in most beds, but the sole mark direction changes by nearly 90° as one of the beds is traced from east to west along the strike. (iii) Most of the beds are massive and are divided into two parts by a bedding joint. However, in the proximal region, if a bed is unusually thin, the bedding joint is absent and the bed shows slightly wavy, plane-laminated structure at places. (iv) Grain orientations are generally statistically non-significant in the upper massive part of the bed in the proximal region and significant in the rest of the bed. Significant grain orientations and graptolite orientations show large deviations from the sole in the distal region. Deviations increase towards the top of the bed. (v) The beds show a change from good grading to poor grading or slight reverse grading from the proximal to distal region. It is considered that the beds were deposited by low concentration, highly turbulent currents. Deposition of the beds took place in two distinct phases. First a 'quick' bed separated from the current was sheared extensively by the overflowing current and on consolidation formed the lower part of the bed. Later deposition in the proximal region from the upper part of the current and the part close to the tail was by settling of individual particles from the suspension. Separation and consolidation of another 'quick' bed in some cases formed the upper part of the beds in the distal region. </p> <p> The depositing currents produced a good vertical and lateral grain size grading in the proximal region, but poor vertical grading in the distal region due to the loss of coarse grains and possibly increased concentration of flocculated clay. Also, the turbidity currents tended to "meander" greatly on slowing down in the distal region. </p> / Thesis / Doctor of Philosophy (PhD)

This architectural thesis challenges the conventional perception of cities as horizontally sprawling realms dominated by towering edifices and skyscrapers. Inspired by Rem Koolhaas' influential book "Delirious New York," which argues that each block represents an independent fantasy, which creates a more cohesive and united version of the city (Koolhaas, 1994). This thesis introduces a groundbreaking outlook that envisions cities as complex networks of functions, neighborhoods, and pathways within an immersive three-dimensional framework. The proposed approach seeks to merge the established city of Manhattan with a new counterpart, driven by enhancing residents' quality of life and addressing the challenges of metropolitan areas. Three key factors underscore the significance of this approach. Firstly, there is a current dearth of connections between buildings and floors, impeding the cohesive fabric of urban life and hindering social interaction and community engagement. Secondly, the rapid population growth in Manhattan has strained the city's surface, leading to challenges in space availability. Additionally, there is a significant lack of public spaces that cater to the community's needs for socializing, outdoor recreation, and access to nature. Moreover, the looming threat of rising sea levels amplifies the urgency of these challenges. By addressing these key factors, the proposed approach aims to revolutionize the urban fabric, creating a more interconnected, sustainable, and resilient cityscape that elevates the well-being of residents and harmonizes with the dynamic nature of urban life. To address these issues, the thesis examines specific components such as existing voids, the street network, and building elements. Through reimagining and redesigning these elements, the goal is to create a unified and sustainable urban environment that aligns with current trends and harnesses emerging technologies. The ultimate aspiration is to achieve a cohesive urban milieu that enhances and reshapes the well- being of residents while adapting to the dynamic nature of urban life / Master of Architecture / This architectural thesis challenges our traditional view of cities as sprawling landscapes dominated by tall buildings. Taking inspiration from Rem Koolhaas' exploration of Manhattan's unique block fantasies in "Delirious New York,". This thesis presents an exciting new perspective. It envisions cities as vibrant hybrid networks, blending various functions, neighborhoods, and pathways within a three-dimensional grid. The proposed approach seeks to merge and integrate the existing city of Manhattan with a new one, aiming to improve the overall quality of life for its residents while addressing the challenges of metropolitan areas. Three significant factors justify this approach. First, there is a lack of connections between buildings and floors, which limits the cohesiveness of urban life. Second, Manhattan's surface is strained due to population growth, demanding innovative solutions. Public spaces encouraging socializing, outdoor activities, and access to natural environments are also insufficient. The rising sea levels add an extra layer of concern. To tackle these complex issues, the thesis explores specific components such as underutilized spaces within the city, streets, and existing buildings. Through imaginative redesign and reimagining, the goal is to create a more harmonious and sustainable urban environment that responds to current trends and technologies. By integrating these elements, the thesis aims to shape cities into vibrant, inclusive, and interconnected spaces that cater to the needs of their communities.

This thesis explores how textile contributes to meaning-making and spatial design in scenography. Through the theoretical lens of performativity theory, it studies three scenes from Cirkus Cirkör’s popular show Knitting Peace. Using semiotic analysis as formulated by Jan-Gunnar Sjölin, the thesis focuses on movement, spatiality and socio-cultural meaning through the three questions; How can textile enhance movement and rhythm? How is it used together with lighting to create changes in spatiality? And What connotations does textile induce, and how do they affect the overall meaning-making in scenography? The results suggest that textile is a valuable material in performance art and scenography. For example, textile behaves in ways that resemble both fluid and solid form. This allows for change of depth and shifting between open and closed spaces on stage with little effort. It also gives means to enhance and enlarge human movement in scale, intensity and time. In Knitting Peace this is used together with lighting design to create off sync layers of reality to symbolise a distorted dreamworld. The thesis shows how we can better understand the way textile affect us by applying perspectives that focus on its different characteristics. Moreover, it demonstrates that an interdisciplinary approach that builds on knowledge from different fields, such as fashion design and performance studies, can greatly benefit our understanding of the potential use of textile in arts.
