A Biomorphic model for automated cloud adaptation

Cloud computing is one of the most discussed areas in computer science in the last years. Although there is an extensive amount of research covering this field, the field of bio-inspired cloud computing is underinvestigated when compared to the general research area. This study tries to find answers on how a biomorphic model can be implemented in the cloud in order to achieve adaptive cloud behaviour. The process of cellular differentiation where cells transform from one type to another, is chosen to be the foundation model for a developed technical model. We define analogies to the cloud where stem cells are blank servers and web servers are cells with a specific function. With a combination of configuration management, version control and cloud deployment systems, an imitation of this biological process is applied in the cloud. The use of automated cloud scaling as a case of adaptive behaviour is the main goal of the research. Two different approaches have been developed for mapping the biological model to the cloud. The first approach consists of a prototype where the signal detection and node activation is being triggered by using the concept of random generated timers. The second approach is based on the concept of random seeds which are used to coordinate the transformation procedure. The project results were able to adapt the cloud based on current needs, with each prototype having its advantages and disadvantages over the other

Frontiers of Adaptive Design, Synthetic Biology and Growing Skins for Ephemeral Hybrid Structures

The history of membranes is one of adaptation, from the development in living organisms to man-made versions, with a great variety of uses in temporary design: clothing, building, packaging, etc. Being versatile and simple to integrate, membranes have a strong sustainability potential, through an essential use of material resources and multifunctional design, representing one of the purest cases where “design follows function.” The introduction of new engineered materials and techniques, combined with a growing interest for Nature-inspired technologies are progressively merging man-made artifacts and biological processes with a high potential for innovation. This chapter introduces, through a number of examples, the broad variety of hybrid membranes in the contest of experimental Design, Art and Architecture, categorized following two different stages of biology-inspired approach with the aim of identifying potential developments. Biomimicry, is founded on the adoption of practices from nature in architecture though imitation: solutions are observed on a morphological, structural or procedural level and copied to design everything from nanoscale materials to building technologies. Synthetic biology relies on hybrid procedures mixing natural and synthetic materials and processes

The Eco Office: Dynamic and Homeostatic Facades inspired by BIOMORPHIM, BIOMIMICRY, and BIOPHILIA

"Come forth into the light of things, Let Nature be your teacher.” ~ William Wordsworth The focus of this dissertation research is to extend and increase an understanding of sustainable building envelope design strategies, with specific focus on transfer of light, air, and heat, within a tropical site setting/context. Biomimetic architecture is a process that is primarily driven by inspiration from natural systems and organisms. Designs and patterns found in nature are often resolved at the “macro” as well as at the “micro/nano” molecular levels, which prompts further investigation into present-day advancements in material science and nanotechnological concepts. Nanotechnology is a way of looking closer at systems and material structures and properties; the translation from biomimetic architecture to the nano-molecular scale of materials thus promotes sustainability in buildings, by providing ways and means to incorporate new technologies and novel material systems into the architectural design of building facades, that will further aid with the successful implementation of passive design strategies, in order to establish comfortable interior lighting, ventilation, and thermal conditions. Extensive literature reviews and material research are utilized for the bio-tonano design process and analyses. Performance of design modules created has been tested using design simulations and reiterative analysis processes. “Taking cues from Nature – creation of responsive (environment and human responsive) architecture” – is the idea that is the primary motivation behind the research focus. The key goal of this research is to propose alternative futures in building envelope design, for a site in Honolulu, which would serve as a digital prototype for similar such investigations into integrating nature-inspired macro and nanotechnology structures and materials into building systems design. Psychophysiology (the mind-body-interaction) and experimental testing is used as part of the final testing and analysis, to assess people’s responses to nature-inspired design and emerging building technologies

Robust neuromorphic coupled oscillators for adaptive pacemakers

Neural coupled oscillators are a useful building block in numerous models and applications. They were analyzed extensively in theoretical studies and more recently, in biologically realistic simulations of spiking neural networks. The advent of mixed-signal analog/digital neuromorphic electronic circuits provides new means for implementing neural coupled oscillators on compact low-power spiking neural network hardware platforms. However, their implementation on this noisy, low-precision and inhomogeneous computing substrate raises new challenges with regards to stability and controllability. In this work, we present a robust, spiking neural network model of neural coupled oscillators and validate it with an implementation on a mixed-signal neuromorphic processor. We demonstrate its robustness showing how to reliably control and modulate the oscillator's frequency and phase shift, despite the variability of the silicon synapse and neuron properties. We show how this ultra-low power neural processing system can be used to build an adaptive cardiac pacemaker modulating the heart rate with respect to the respiration phases and compare it with surface ECG and respiratory signal recordings of dogs at rest. The implementation of our model in neuromorphic electronic hardware shows its robustness on a highly variable substrate and extends the toolbox for applications requiring rhythmic outputs such as pacemakers.Comment: 14 pages, 4 figure

Nature-inspired survivability: Prey-inspired survivability countermeasures for cloud computing security challenges

As cloud computing environments become complex, adversaries have become highly sophisticated and unpredictable. Moreover, they can easily increase attack power and persist longer before detection. Uncertain malicious actions, latent risks, Unobserved or Unobservable risks (UUURs) characterise this new threat domain. This thesis proposes prey-inspired survivability to address unpredictable security challenges borne out of UUURs. While survivability is a well-addressed phenomenon in non-extinct prey animals, applying prey survivability to cloud computing directly is challenging due to contradicting end goals. How to manage evolving survivability goals and requirements under contradicting environmental conditions adds to the challenges. To address these challenges, this thesis proposes a holistic taxonomy which integrate multiple and disparate perspectives of cloud security challenges. In addition, it proposes the TRIZ (Teorija Rezbenija Izobretatelskib Zadach) to derive prey-inspired solutions through resolving contradiction. First, it develops a 3-step process to facilitate interdomain transfer of concepts from nature to cloud. Moreover, TRIZ’s generic approach suggests specific solutions for cloud computing survivability. Then, the thesis presents the conceptual prey-inspired cloud computing survivability framework (Pi-CCSF), built upon TRIZ derived solutions. The framework run-time is pushed to the user-space to support evolving survivability design goals. Furthermore, a target-based decision-making technique (TBDM) is proposed to manage survivability decisions. To evaluate the prey-inspired survivability concept, Pi-CCSF simulator is developed and implemented. Evaluation results shows that escalating survivability actions improve the vitality of vulnerable and compromised virtual machines (VMs) by 5% and dramatically improve their overall survivability. Hypothesis testing conclusively supports the hypothesis that the escalation mechanisms can be applied to enhance the survivability of cloud computing systems. Numeric analysis of TBDM shows that by considering survivability preferences and attitudes (these directly impacts survivability actions), the TBDM method brings unpredictable survivability information closer to decision processes. This enables efficient execution of variable escalating survivability actions, which enables the Pi-CCSF’s decision system (DS) to focus upon decisions that achieve survivability outcomes under unpredictability imposed by UUUR

Mixed Reality Interiors: Exploring Augmented Reality Immersive Space Planning Design Archetypes for the Creation of Interior Spatial Volume 3D User Interfaces

Augmented reality is an increasingly relevant medium of interaction and media reception with the advances in user worn or hand-held input/output technologies endowing perception of the digital nested within and reactive to the native physical. Our interior spaces are becoming the media interface and this emergence affords designers the opportunity to delve further into crafting an aesthetics for the medium. Beyond having the virtual assets and applications in correct registration with the real-world environment, critical topics are addressed such as the compositional roles of virtual and physical design features including their purpose, modulation, interaction potentials and implementation into varying indoor settings. Examining and formulating methodologies for mixed reality interior 3D UI schemes derived from the convergence of digital media and interior design disciplines comprise the scope of this design research endeavor. A holistic approach is investigated to produce a framework for augmented reality 3D user interface interiors through research and development of pattern language systems for the balanced blending of complimentary digital and physical design elements. These foundational attributes serve in the creation, organization and exploration of interactive possibilities and implications of these hybrid futuristic spatial interface layouts.M.S., Digital Media -- Drexel University, 201

Conditions Variable: Assemblage Theory and Systems Theory in Creative Practice

This dissertation will situate the twenty-first century phenomenon of Assemblage theory, which originated in the field of philosophy, within the last 100 years of creative practice. Drawing from Manuel DeLanda’s application of Assemblage theory, I will devise a means to discuss creative practice without reducing its analysis to ‘structured fields’ or ‘closed systems’. Rather, comparisons will be made between a system and an assemblage to illustrate how the two part ways, and find common ground. To better understand the way in which systems have been applied in artistic practice, an investigation of two major twentieth-century paradigm shifts will be examined. The first example is the Bauhaus school and its post-European formal offshoot in America, the New Bauhaus, and how it adapted its European predecessor’s principles of design. The second is the technological revolution, which engendered Jack Burnham’s Systems Esthetics, Experiments in Art and Technology (EAT) and the Center for Advanced Visual Studies (CAVS) at the Massachusetts Institute of Technology (MIT). In light of these developments, I argue that a flexible, descriptive, Assemblage theory is needed to better articulate how art (the work and its making) functions within an expanded field of practice as it now exists. The adaptable and transmutable nature of Assemblage theory is also illustrated through example. In the process this dissertation will offer new ways to articulate and understand creative practice and propose a new strategy for art to be understood. Finally, I will employ Assemblage theory to analyze my own creative endeavours

Embedding Intelligence. Designerly reflections on AI-infused products

Artificial intelligence is more-or-less covertly entering our lives and houses, embedded into products and services that are acquiring novel roles and agency on users. Products such as virtual assistants represent the first wave of materializa- tion of artificial intelligence in the domestic realm and beyond. They are new interlocutors in an emerging redefined relationship between humans and computers. They are agents, with miscommunicated or unclear proper- ties, performing actions to reach human-set goals. They embed capabilities that industrial products never had. They can learn users’ preferences and accordingly adapt their responses, but they are also powerful means to shape people’s behavior and build new practices and habits. Nevertheless, the way these products are used is not fully exploiting their potential, and frequently they entail poor user experiences, relegating their role to gadgets or toys. Furthermore, AI-infused products need vast amounts of personal data to work accurately, and the gathering and processing of this data are often obscure to end-users. As well, how, whether, and when it is preferable to implement AI in products and services is still an open debate. This condition raises critical ethical issues about their usage and may dramatically impact users’ trust and, ultimately, the quality of user experience. The design discipline and the Human-Computer Interaction (HCI) field are just beginning to explore the wicked relationship between Design and AI, looking for a definition of its borders, still blurred and ever-changing. The book approaches this issue from a human-centered standpoint, proposing designerly reflections on AI-infused products. It addresses one main guiding question: what are the design implications of embedding intelligence into everyday objects
