Show moreMulti-Gate Field-E ect Transistors are transistors with more than one gate that allows continuation of Moore's Law and performance increases for CMOS tran- sistors. Introduction of multi-gate devices has been a turning point for the semi- conductor industry in facilitating transition from planar to 3D structures. Intel rst introduced commercial products using 3D structures (called Tri-Gate transistors) in late 2011 with Ivy Bridge CPUs using 22nm processes. Signi cant performance gains have been reported; i.e., 37% performance increase at low voltage and 50% power reduction. Multi-gate transistors based on 3D structures can vary greatly in their con guration and architectures leading to ambiguity in their design. It is necessary to investigate the performance of datapath circuits when multi-gate and independent- gate devices replace the conventional planar transistors. Therefore, key objective of this work has been to analyze these transistors' performance and to design new dat- apath circuits to leverage the inherent qualities of multi-gate transistor structures. Multiple-gate devices can be modeled using the BSIM-CMG (Common Multi- Gate) and BSIM-IMG (Independent Multi-Gate) compact models from University of Berkeley Device Group. In this research, both device types have been characterized for a variety of parameters to study their basic properties, functionality and to build a foundation for improved circuit designs. In particular, BSIM-CMG devices have been compared with CMOS planar technology demonstrating signi cant advantages in all design metrics, meanwhile the BSIM-IMG have been used to design new gates and improve datapath designs. In the rst part of this study, essential logic gates, i.e. Inverter, NAND and NOR, have been implemented using BSIM-CMG devices. After being analyzed and compared with the CMOS technology, a 32% reduction on dynamic power consump- tion and 82% reduction for the leakage current has been obtained. For a compre-hensive look on full adder designs, several novel adder architectures have been im- plemented including ultra low power and minimum number of transistor (10T) de- signs. The analysis of these implementations shows 54% dynamic power reduction, 98% static current reduction and 26% delay reduction. These results lead to a 68% improvement on the Power-Delay product comparing with the 32nm CMOS planar technology. In order to investigate dynamic logic circuits with multi-gate transistors, two recent dynamic circuit techniques have been implemented with novel enhancements to reduce the leakage current. Data Driven Dynamic Logic (D3L) and Split-Path Data Driven Dynamic Logic (SPD3L) have been used to analyze the dynamic logic circuits resulting in 11% reduced dynamic power, 52% reduced leakage current and 33% reduced delay. Second part of this study deals with the independent gate devices. Using the BSIM-IMG model, new XOR/XNOR logic gate designs are introduced for im- plementing novel low-power adders. With these new adder architectures, the average improvement on Dynamic power is an 8% and the designs are 6% faster. Furthermore, a new design technique is proposed combining the possible modes (Short Gate-SG, Low-Power-LP, Independent Gate-IG) that the BSIM-IMG provides. Using this novel mixed design, the Power-Delay product is improved on average 7.2% and 54%, com- pared to the Short-Gate (SG) and Low-Power (LP) modes, respectively. The properties of the BSIM-IMG logic have been applied to improve the Dy- namic logic designs as well. The Domino and SPD3L design techniques have been implemented and enhancements such as merging the pull-up transistors have been proposed for sleep and power-gating techniques. With these enhancements, the Dy- namic power is reduced 13% in average and the designs are 18% faster. The trade-o is an increase on leakage current of 8%. Another major contribution of the work has been the development of shell script les for generating a custom toolbox for datapath designs with multi-gate and independent-gate transistors.

Show moreThe district and neighborhood of Bronzeville, located in the Near South Side of Chicago, suffers from crime, unemployment, abandonment, and urban decay; more so than many of its metropolitan peers such as New York City, Los Angeles, or San Francisco.In Latin America, multidisciplinary operations and strategies focused on the investment in public spaces, mobility, and public assets have been successful in transforming decaying neighborhoods and redeveloping slums and blighted areas turning them into vibrant communities.Contextualizing and abstracting such strategies has the potential to import such ideas into new urban contexts; in this case, the United States of America, and to be implemented over the decaying North American urban fabric.

Show moreThe rhetoric of today’s economy has framed entrepreneurship as a key contributor to inventing the future, which raises questions about who is counted as an insider, how the future is being designed, and for whom. The concentration of future-making has too long been in the hands of a few, given future’s tremendous impact on the many. This dissertation joins the growing body of scholarly explorations on channeling the design capacity to transition toward a future with a plural world system, where the economy offers a multiplicity of possibilities. Central to this exploration is to rethink how shaping futures might be done differently, with different people, and in different forms.By incorporating feminist temporality, I challenge the established mode of design investigation. My empirical chapters demonstrate the ways in which sharpening our temporal sensitivity could impact what we study, how we study it, and what we can find. In particular, I rearrange the power dynamics in design activities by opening up the position of knower to the emerging collectives. I then introduce the concept of designing a time-space yet to come that makes you wonder—an open invitation to rethink who we are and what we want to become.While it remains to be seen whether this contribution will have a meaningful impact on design knowledge, I argue that it makes a solid case for incorporating feminism in design. Feminist theory offers the theoretical underpinning for ontological reframing of design and helps us understand what other forms of design practice are emerging in this era of increasing complexity. I conclude with my take on an emerging design practice where the fundamental element of design is to enable other ways of knowing to inquire about what they truly want to become.

Title: Sustainable Solutions in Complex Spaces of Innovation

Show moreEven though the interconnectivity between human activities and the integrity of ecological systems has long been recognized, the development of design practices that account for such interconnectivity can be considered relatively new. As such, contemporary institutions and their arrangements were not designed accordingly to their potential to promote sustainable and equitable flows of different types of resources; they lack the capability and structure to operate in the speed and scale in which humans are dynamically interacting with themselves, and with the natural environment. As the world has passed the 7.5 billion mark, such a condition is generating unintended socio-ecological-technical consequences being empowered by the fast-changing technology industry. New lenses and models for understanding the connectivity of social, ecological and technical systems underlying contemporary institutional arrangements are required to advance expertise in redirecting the flow of different types of resources for the sustainability of these systems. However, how humans perceive systems is largely framed by who is included in the discussion and the experiences and interests that they bring to bear. Even though there will always be a discrepancy between what is perceived, and the actual system at play, there are greater opportunities to expand such perception by drawing more deeply on systems thinking and the notion of resources. This dissertation advances design knowledge in the pursuit of bridging the gap between theoretical discourses and the pragmatism necessary to intervene socio-ecological-technical dynamics by exploring how designers might embed principles of sustainability into choice-making processes for innovation, and it proposes a new approach through which designers can advance their practices in enabling more sustainable flows of resources.

Show moreThis research is motivated by my industry experience of working with small manufacturers in the high technology industry market space and large manufacturers in the telecom and healthcare industry market spaces. In these industries, small manufacturers thrive on specialization and focus on breakthrough innovation to maintain product differentiation and premium positioning and to sustain competition. In contrast, large manufacturers enjoy the benefits of economies of scale that provide cost efficiencies and use price as major differentiating factor. This research work endeavors to model asymmetric competition that emerges endogenously in industries where scale and scope economies interact to force firms to adopt specialized strategies and address the below research questions:1. How does the cost structure shaped by scope and scale economies in engineering, sales and service drive asymmetric product line choices?2. What channel coordination problems arise in this context?3. How can manufacturers redesign their operating mechanism and sales force to optimize the channel?

Show moreTo observe that the unique architectural ornaments that make up the body of work of Louis Henri Sullivan (1856-1924) emulate nature is to state a reality so obvious that it is both pedantic and droll. To use the double entendre that those natural forms drew on Darwinism, however, is to make several more specific claims. First, it can be credibly established that the system of architectural ornament that was the primary contribution of Louis Sullivan to the discipline of architecture was directly inspired by Sullivan’s synthesis of the thesis of natural selection contained within the pages of Asa Gray’s botanical manual. Second, the circumstances of that moment of synthesis reveal that the reason for Sullivan’s Darwinism was not merely the desire to emulate nature, but rather to signify the end of faith. Finally, Sullivan’s synthesis of various Darwinisms drew not only on the thesis for his own artistic inspiration, he drew on the substance of Darwin’s arguments to formulate a secular theory of the nature of inspiration and the technique of design. In the years following, this theory has become the primary technique by which design is taught.Louis’ unique education, which was tied to Darwinism from the very beginning, gave him an unusual perspective on the challenges of architectural design in the industrial age. The economic circumstances of his life as a first-generation immigrant exposed him to just the right education to lead him to explore evolutionary science as the inspiration for design. To be clear, the content of the thesis of natural selection was entirely irrelevant to the theory and practice of architecture in the nineteenth century. Yet by the end of the century the broad consensus among architects, historians, and theorists alike was that there was a, “close and causal relationship,” between Darwinism and modern architecture. Sullivan’s theory drew on Darwinian ideas to dismiss theological styles as empty formalisms, reveal the racism of ethnographic accounts for architectural forms, and argue for the evolution of an American Architecture, liberated from its colonialist origins. The context within which that shift occurred is significant. The justification for nearly every work of architecture in human history prior to the middle of the nineteenth century was some form of god. Mid-nineteenth century architecture in the United States was composed of a variety of regional ethnic styles intended to represent the ethnic origins, religious affiliations, moral inclinations, and nationalist allegiances of an array of displaced immigrant communities. The Civil War laid bare the reality that such ethnic styles represented a segregationist and racialized idea of the modern world. Over the course of the late nineteenth century, the profession of architecture was forced to abandon theological justifications for the practice of architecture as scientifically invalid, morally corrupt, and motivated by racism. This was Sullivan’s full idea: Put instinct before reason in priority, and engage in the iterative analysis of various instincts about the situation. Observe the patterns that emerge. Explore those instincts, until you find that your patterns merge with universal patterns. Do not fear error, as it makes the work alive. The capacity to capture that living essence is in all of us, individually and collectively, not some external force. The most-right instincts are ones in which the resulting form is a demonstration of its function. To understand what Sullivan meant with this we must see it as a Darwinian idea. Instinct is an animal property, a capacity which we share with other species. For Darwin, this sharing of instinct is essential for interspecies empathy. The antithesis of instinct is reason, which Sullivan describes as secondary. Reason is cold and lifeless, but also correct. True reason, Sullivan claims, is learned by experiment, and example. The greatest art speaks not just to our reason, but to our instinct. This, then is the task of the designer – to temper instinct with reasoned evaluation. Sullivan argues that it begins with an intuition, an idea he drew from Darwin’s Descent of Man.
