The Georgia Institute of Technology is a public research university in Atlanta, Georgia, in the United States. It is a part of the University System of Georgia and has satellite campuses in Savannah, Georgia; Metz, France; Athlone, Ireland; Shanghai, China; and Singapore.The educational institution was founded in 1885 as the Georgia School of Technology as part of Reconstruction plans to build an industrial economy in the post-Civil War Southern United States. Initially, it offered only a degree in mechanical engineering. By 1901, its curriculum had expanded to include electrical, civil, and chemical engineering. In 1948, the school changed its name to reflect its evolution from a trade school to a larger and more capable technical institute and research university.Today, Georgia Tech is organized into six colleges and contains about 31 departments/units, with emphasis on science and technology. It is well recognized for its degree programs in engineering, computing, business administration, the science, architecture, and liberal arts.Georgia Tech's main campus occupies part of Midtown Atlanta, bordered by 10th Street to the north and by North Avenue to the south, placing it well in sight of the Atlanta skyline. In 1996, the campus was the site of the athletes' village and a venue for a number of athletic events for the 1996 Summer Olympics. The construction of the Olympic village, along with subsequent gentrification of the surrounding areas, enhanced the campus.Student athletics, both organized and intramural, are a part of student and alumni life. The school's intercollegiate competitive sports teams, the four-time football national champion Yellow Jackets, and the nationally recognized fight song "Ramblin' Wreck from Georgia Tech", have helped keep Georgia Tech in the national spotlight. Georgia Tech fields eight men's and seven women's teams that compete in the NCAA Division I athletics and the Football Bowl Subdivision. Georgia Tech is a member of the Coastal Division in the Atlantic Coast Conference. Wikipedia.

Globalization and ever-changing customer demands resulting in product customization, variety and time to market have intensified enormous competition in automotive and aerospace, manufacturing worldwide. Manufacturers are under tremendous pressures to meet changing customer needs quickly and cost effectively without sacrificing quality. Responding to these challenges manufacturers have offered flexible and reconfigurable assembly systems. However, a major challenge is how to obtain production volume flexibility for a product family with low investment and capability to yield high product quality and throughput while allowing quick production ramp-up. Overcoming these challenges involves three requirements which are the focus of this proposal: (1) Model reconfigurable assembly system architecture. The system architecture should purposefully take into account future uncertainties triggered by product family mix and product demands. This will require minimizing system changeability while maximizing system reusability to keep cost down; (2) Develop novel methodologies that can predict process capability and manage product quality for given system changeability requirements; and (3) Take advantage of emerging technologies & rapidly integrate them into existing production system, for e.g., new joining processes (Remote Laser Welding) and new materials. This project will address these factors by developing a self-resilient reconfigurable assembly system with in-process quality improvement that is able to self-recover from (i) 6-sigma quality faults; and (ii) changes in design and manufacturing. In doing so, it will go beyond state-of-the-art and practice in following ways: (1) Since current system architectures face significant challenges in responding to changing requirements, this initiative will incorporate cost, time and risks involving necessary changes by integrating uncertainty models; decision models for needed changes; and system change modelling; and (2) Current in-process quality monitoring systems use point-based measurements with limited 6-sigma failure root cause identification. They seldom correct operational defects quickly and do not provide in-depth information to understand and model manufacturing defects related to part and subassembly deformation. Usually, existing surface-based scanners are used for parts inspection not in-process quality control. This project will integrate in-line surface-based measurement with automatic Root Cause Analysis, feedforward/feedback process adjustment and control to enhance system response to fault or quality/productivity degradation. The research will be conducted for reconfigurable assembly system with multi-sector applications. It will involve system changeability/adaptation and in-process quality improvement for: (i) Automotive door assembly for implementing an emerging joining technology, e.g. Remote Laser Welding (RLW), for precise closed-loop surface quality control; and (ii) Airframe assembly for predicting process capability also for precise closed-loop surface quality control. Results will yield significant benefits to the UKs high value manufacturing sector. It will further enhance the sector by accelerating introduction of new emerging eco-friendly processes, e.g., RLW. It will foster interdisciplinary collaboration across a range of disciplines such as data mining and process mining, advanced metrology, manufacturing, and complexity sciences, etc. The integration of reconfigurable assembly systems (RAS) with in-process quality improvement (IPQI) is an emerging field and this initiative will help to engender the development into an internationally important area of research. The results of the research will inform engineering curriculum components especially as these relate to training future engineers to lead the high value manufacturing sector and digital economy.

Gold nanoparticles have been used in biomedical applications since their first colloidal syntheses more than three centuries ago. However, over the past two decades, their beautiful colors and unique electronic properties have also attracted tremendous attention due to their historical applications in art and ancient medicine and current applications in enhanced optoelectronics and photovoltaics. In spite of their modest alchemical beginnings, gold nanoparticles exhibit physical properties that are truly different from both small molecules and bulk materials, as well as from other nanoscale particles. Their unique combination of properties is just beginning to be fully realized in range of medical diagnostic and therapeutic applications. This critical review will provide insights into the design, synthesis, functionalization, and applications of these artificial molecules in biomedicine and discuss their tailored interactions with biological systems to achieve improved patient health. Further, we provide a survey of the rapidly expanding body of literature on this topic and argue that gold nanotechnology-enabled biomedicine is not simply an act of 'gilding the (nanomedicinal) lily', but that a new 'Golden Age' of biomedical nanotechnology is truly upon us. Moving forward, the most challenging nanoscience ahead of us will be to find new chemical and physical methods of functionalizing gold nanoparticles with compounds that can promote efficient binding, clearance, and biocompatibility and to assess their safety to other biological systems and their long-term term effects on human health and reproduction (472 references). © 2012 The Royal Society of Chemistry.

In an information processing apparatus, a comparing unit determines whether the response time of each transaction falls within an acceptable time range that is specified previously. For each time window, a first calculation unit calculates a load of processes executed in parallel by the servers in a specified tier, based on transaction data of individual transactions. Further, a second calculation unit calculates a total progress quantity in each time window, based on the transaction data of transactions whose respective response times are determined to fall within the acceptable time range. A determination unit determines a specific load value as a threshold at which the total progress quantity begins to decrease in spite of an increase of the load.

Missile defense takes place in an uncertain and dynamic environment, so multi-sensor fusion must be employed to aggregate and merge disparate data from the battlefield. However, the fusion process is hindered by the vast amount of uncertainty in operational contexts, such as imprecise measurements and varying environmental conditions. Various algorithms and fusion processes have been developed to manage this uncertainty so that accurate assessment of threats can still be obtained. However, little effort has been made at determining which methods and algorithms are best suited under different conditions and uncertainty models. In our Adaptive Management and Mitigation of Uncertainty in Fusion (AMMUF) project, we will use decision-theoretic probabilistic relational models (DT-PRMs) to model the fusion process and the different design and algorithmic decisions that can be made by system engineers and fusion operators. DT-PRMs can determine optimal decisions under inherent domain uncertainty in a variety of operational conditions. Our AMMUF tool will enable system engineers to determine the optimal fusion configuration in different missile defense contexts, giving battlefield operators the most accurate and efficient information about missile threats.

Scientific research performed with the involvement of the broader public (the crowd) attracts increasing attention from scientists and policy makers. A key premise is that project organizers may be able to draw on underused human resources to advance research at relatively low cost. Despite a growing number of examples, systematic research on the effort contributions volunteers are willing to make to crowd science projects is lacking. Analyzing data on seven different projects, we quantify the financial value volunteers can bring by comparing their unpaid contributions with counterfactual costs in traditional or online labor markets. The volume of total contributions is substantial, although some projects are much more successful in attracting effort than others. Moreover, contributions received by projects are very uneven across time-a tendency toward declining activity is interrupted by spikes typically resulting from outreach efforts or media attention. Analyzing user-level data, we find that most contributors participate only once and with little effort, leaving a relatively small share of users who return responsible for most of the work. Although top contributor status is earned primarily through higher levels of effort, top contributors also tend to work faster. This speed advantage develops over multiple sessions, suggesting that it reflects learning rather than inherent differences in skills. Our findings inform recent discussions about potential benefits from crowd science, suggest that involving the crowd may be more effective for some kinds of projects than others, provide guidance for project managers, and raise important questions for future research.

Recent experiments on nanostructured materials, such as nanoparticles, nanowires, nanotubes, nanopillars, thin films, and nanocrystals have revealed a host of "ultra-strength" phenomena, defined by stresses in a material component generally rising up to a significant fraction >110 of its ideal strength - the highest achievable stress of a defect-free crystal at zero temperature. While conventional materials deform or fracture at sample-wide stresses far below the ideal strength, rapid development of nanotechnology has brought about a need to understand ultra-strength phenomena, as nanoscale materials apparently have a larger dynamic range of sustainable stress ("strength") than conventional materials. Ultra-strength phenomena not only have to do with the shape stability and deformation kinetics of a component, but also the tuning of its physical and chemical properties by stress. Reaching ultra-strength enables "elastic strain engineering", where by controlling the elastic strain field one achieves desired electronic, magnetic, optical, phononic, catalytic, etc. properties in the component, imparting a new meaning to Feynman's statement "there's plenty of room at the bottom". This article presents an overview of the principal deformation mechanisms of ultra-strength materials. The fundamental defect processes that initiate and sustain plastic flow and fracture are described, and the mechanics and physics of both displacive and diffusive mechanisms are reviewed. The effects of temperature, strain rate and sample size are discussed. Important unresolved issues are identified. © 2010 Elsevier Ltd.

Despite the challenged contention that consumers serve more onto larger dinnerware, it remains unclear what would cause this and who might be most at risk. The results of five studies suggest that the neglected Delboeuf illusion may explain how the size of dinnerware creates two opposing biases that lead people to overserve on larger plates and bowls and underserve on smaller ones. A countercyclical sinus-shaped relationship is shown to exist between these serving biases and the relative gap between the edge of the food and the edge of the dinnerware. Although these serving biases are difficult to eliminate with attention and education, changing the color of one's dinnerware or tablecloth may help attenuate them. By showing that the Delboeuf illusion offers a mechanistic explanation for how dinnerware size can bias serving and intake, we open new theoretical opportunities for linking illusions to eating behavior and suggest how simple changes in design can improve consumer welfare. © 2011 by JOURNAL OF CONSUMER RESEARCH, Inc.

There is an unmet demand for nano-scaled ultra-low-power low-cost radios to address field-deployable and massively producible sensing and communication networks in future military and commercial applications. To overcome the limitations in existing bulky and power hungry radios, we propose a disruptive solution by exploiting the holistic integration of THz radio transceiver system, on-chip antenna, and energy harvesting technologies in a form-factor smaller than 10^-11 cubic meter. The proposed THz radio adopts a novel bidirectional circuit-sharing architecture in scaled CMOS that can be configured as a harmonic oscillator transmitter for THz signal transmitting or a super-harmonic regenerative receiver for THz signal receiving. This THz bidirectional transceiver substantially reduces the size and power while ensuring an adequate link-budget for communication. The THz radio can readily achieve a data rate over 10Mbit/s for one meter using On-Off-Keying (OOK) modulation. A multi-feed on-chip antenna performs on-chip THz power combining, splitting, and radiation, which further reduces the overall system size. Various energy harvesting technologies and their integration with the CMOS THz radio chip will be explored. The collaborative team includes Digital Analog Integration and Georgia Institute of Technology and offers related technical expertise, successful track records, and necessary facilities for the proposed research.

This proposal addresses the challenge of providing weather and climate information to support the operation, management and planning for wind-energy systems. There is a growing need for extended range forecast information as wind power increases its penetration into the grid. Future scenarios on decadal time scales are needed to support assessment of wind farm siting, long-term purchase agreements and the regulatory environment. To address this challenge, CFAN has developed a hybrid statistical/dynamical forecasting scheme for delivering probabilistic forecasts on time scales from one day to seven months using what is arguably the best forecasting system in the world (European Centre for Medium Range Weather Forecasting, ECMWF). The project also provides a framework to assess future wind power through developing scenarios of inter-annual to decadal climate variability and change. The Phase I project conducted a pilot study for the Electric Reliability Council of Texas (ERCOT) region. The project included: assembly and evaluation of relevant data sets; development and evaluation of an ensemble prediction framework for forecasting regional wind power generation and demand on time scales from days to months; development of strategies to assess long term (decadal) changes to the regional wind power environment; and formulation of an online tool that provides decision makers with actionable information related to wind power forecasts and projections. The proposed Phase II project will further develop the capabilities begun during Phase II and extend the project to include the continental U.S. and offshore regions. The objective is to develop a commercially viable capability for the growing array of diversified users in the wind energy forecast market. Commercial Applications and Other Benefits: Customers and end-users of these products include wind farm operators, regional power providers, grid system operators, and energy sales and trading. The other target application is assessment of wind energy project feasibility, to select favorable sites where wind is strongest and year-to-year variability is minimized. Customers for such assessments are project owners, government planners, regulatory agencies, and investors.

There are major technical and financial barriers that are preventing Si photonics and optoelectronics to transition from R & D to commercial product domain. The main technical challenge is the nanometric scale precision required for proper functioning of Si photonic devices. High index contrast of Si with its cladding materials allows reducing the size of photonic elements and hence allows packing more and more functionalities in smaller area. However, the same high index contrast results in very high sensitivity of these resonators to nanometer scale variations. Similarly, on the financial side, the cost of fabricating these devices has to be reduced before Si photonics can go into commercial production. Sinoora Inc. plans to overcome these major challenges in this STTR Phase II project by developing a robust and low-cost manufacturing process that can deliver very precise Si photonic and optoelectronic circuits.
