Drivers using information from an Advanced Traveler Information System (ATIS) could potentially make better travel decisions to reduce travel time and increase trip reliability, thereby benefiting both guided drivers as well as those without such access. However, market penetration of ATIS can have dramatic effects on the performance of the transportation system in terms of overall benefits conferred as well as the distributional effects between guided and unguided drivers. Because market penetration will be determined both by private market structure and public policies, the effective deployment of ATIS depends critically on the private and public organizations that will provide these services. An understanding of the relationship between transportation system performance and ATIS market penetration provides important insights into a sustaining market structure for the ATIS industry. This thesis provides an empirical study of the impact of ATIS on transportation network quality of service using an application of DynaMIT (Dynamic network assignment for the Management of Information to Travelers). An analysis of the simulation results serves to inform the public and private stakeholder positions in the creation of a better market for ATIS. The main results are that the provision of dynamic route guidance can simultaneously benefit the individual performance of drivers...

This thesis reports on two technology and policy issues directly related to hydrogen economy. The first issue concentrates on the end-use application of hydrogen as a transportation fuel, and deals with the following question: what is the place of hydrogen fuel cell vehicles among the new, more-efficient advanced vehicle technologies. Our analysis indicates that fuel cell vehicles using hydrogen from fossils fuels offer no significant energy efficiency advantage over hybrid vehicles in urban driving cycle. Therefore, there is a strong justification for federal support for hybrid vehicles that will achieve similar results, quicker. The second issue focuses on another important technology and policy question related to large scale hydrogen production: are there any comparative efficiency, cost and/or political advantages of using an advanced nuclear reactor coupled to a thermochemical conversion plant to produce hydrogen with respect using a conventional nuclear reactor coupled to an electrolysis plant? The results suggest that given the existing technical and cost uncertainties, developing an advanced nuclear reactor technology solely for the use of thermochemical hydrogen production is not good energy (R&D) policy. Electrolysis is a more promising alternative provided a more efficient electrolysis technology can be coupled to an advanced nuclear energy (i.e. electricity) source at a reasonable cost. Therefore...

The primary aim of this thesis is to advance the theory of advanced locomotion mechanical counter pressure (MCP) spacesuits by studying the changes in the human body shape during joint motion. Two experiments take advantage of three-dimensional laser scan technology to measure the shape changes of the human body. The first experiment is an analysis of the surface area and volume of the thigh, knee, calf, and entire leg during knee flexion. The second experiment is an analysis of the full-field strain on the skin surface of the leg during knee flexion. A repeatable and quantitative technique for mapping the leg skin strain field is developed. The results of the algorithm indicate the magnitude of strain over the entire surface of the leg, as well as the direction of minimum leg skin stretching during knee flexion. For 88% of the leg surface, knee flexion causes skin strain between -0.3 and 0.3 (less than 30% contraction or extension). However, just below the patella, longitudinal strain is as high as 0.7, and at the knee hollow, it is as low as -0.6. Circumferential strain values are as high as 1.0 and 0.5 just below the patella and over the calf muscle, respectively, and along the anterior surface of the lower leg, they are as low as -0.7. The leg area...

Coal is widely relied upon as a fuel for electric power generation, and pressure is increasing to limit emissions of the CO2 produced during its combustion because of concerns over climate change. In order to continue the use of coal without emitting CO2, low cost technologies must be developed for capturing CO2 from power plants. Current CO2 capture technology is expensive, both in terms of capital and operating cost, so research and development efforts will be heavily relied upon to improve the economic profile of the technologies. With scarce resources available for R&D, and a number or different technologies competing for these funds, efforts must be prudently prioritized in order for successful advancements to be realized. This thesis assesses the state-of-the-art CO2 capture technologies available today, as well as the leading technology options for improvement. It also examines types of R&D, government and industry roles in R&D efforts, and methods and tools for managing these efforts. From these analyses, qualitative conclusions about how to prioritize CO2 capture technology R&D efforts to ensure advancement are offered.; (cont.) There are three technological pathways for CO2 capture - post-combustion, oxy-fired, and pre-combustion capture - and several technology options for improvement in each pathway. There are currently no clear winners...

This paper evaluates the advanced coal technology research, development and demonstration programs at the U.S. Department of Energy since the 1970s. The evaluation is conducted from a portfolio point of view and derives implications for future program design and implementation. The evaluation framework consists of four categories of criteria that assess the portfolio from strategy, diversity, partnership, and project merit points of view. The analysis of the successes and the failures of the past programs in technical, financial and managerial respects shows that these programs are reasonably successful in (1) remarkably advancing coal technologies to enable the U.S. to use coal as its major energy resource in the electricity sector when facing more stringent environmental regulation or possibly even in a greenhouse gas constrained world; (2)accumulating effective program management experience, especially involving industry in technology development from the beginning of the process to facilitate future deployment. Among these successes, a number of important features incorporated in the CCTDP are especially worth noting. These features are: (1) The program goal was well defined, which was accelerating commercialization of ACTs;; (cont.) (2) All projects have been fully funded up front...

The deployment of fuel recycling through either CONFU (COmbined Non-Fertile and UO2 fuel) thermal watercooled reactors (LWRs) or fast ABR (Actinide Burner Reactor) reactors is compared to the Once-Through LWR reactor system in terms of accumulation of actinides over the next 100 years under the assumption of a growing worldwide demand for nuclear energy. It is assumed that the growth rate is about 2.1% per year up to 2053, with alternative scenarios after that date. The transuranics (TRU) stored in temporary repositories, the TRU sent to permanent repositories, the system cost and a vulnerability index toward proliferation are calculated by the CAFCA code and taken as key figures of merit. Deployment of the ABRs is assumed to occur later (2028) than the CONFU LWRs (2015), whose technology requires less extensive additional R&D. Through 2050 the CONFU strategy performs better than the ABR strategy. The CONFU LWRs in our model yield zero net TRU incineration while the ABRs have a net consumption of TRU. Compared to the Once-Through strategy, by 2050 the CONFU (respectively ABR) strategy reduces by about 22% (respectively 16%) the total inventory of TRU in the system. This reduction corresponds to the TRU production being avoided by CONFU LWRs or being incinerated in ABRs compared to the TRU produced in the traditional LWRs used in the Once-Through strategy.; (cont.) The net consumption of TRU in ABRs makes the ABR strategy more attractive in a longer term. By 2100...

Imaging speed is a crucial consideration for magnetic resonance imaging (MRI). The speed of conventional MRI is limited by hardware performance and physiological safety measures. "Parallel" MRI is a new technique that circumvents these limitations by utilizing arrays of radiofrequency detector coils to acquire data in parallel, thereby enabling still higher imaging speeds. In parallel MRI, coil arrays are used to accomplish part of the spatial encoding that was traditionally performed by magnetic field gradients alone. MR signal data acquired with coil arrays are spatially encoded with the distinct reception patterns of the individual coil elements. T[he quality of parallel MR images is dictated by the accuracy and efficiency of an image reconstruction (decoding) strategy. This thesis formulates the spatial encoding and decoding of parallel MRI as a generalized linear inverse problem. Under this linear algebraic framework, theoretical and empirical limits on the performance of parallel MR image reconstructions are characterized, and solutions are proposed to facilitate routine clinical and research applications. Each research study presented in this thesis addresses one or more elements in the inverse problem, and the studies are collectively arranged to reflect three progressive stages in solving the inverse problem: 1) determining the encoding matrix...

This work investigates whether the advanced light water reactor designs with passive safety systems are more desirable than advanced reactor designs with active safety systems from the point of view of uncertainty in the performance of safety systems as well as the economic implications of the passive safety systems. Two advanced pressurized water reactors and two advanced boiling water reactors, one representing passive reactors and the other active reactors for each type of coolant, are compared in terms of operation and responses to accidents as reported by the vendors. Considering a simplified decay heat removal system that utilizes an isolation condenser for decay heat removal, the uncertainty in the main parameters affecting the system performance upon a reactor isolation accident is characterized when the system is to rely on natural convection and when it is to rely on a pump to remove the core heat. It is found that the passive system is less certain in its performance if the pump of the active system is tested at least once every five months. In addition, a cost model is used to evaluate the economic differences and benefits between the active and passive reactors. It is found that while the passive systems could have the benefit of fewer components to inspect and maintain during operation...

Nanofluids at very low concentrations experimentally exhibit a substantial increase in Critical Heat Flux (CHF) compared to water. The use of a nanofluid in the In-Vessel Retention (IVR) severe accident management strategy, employed in Advanced Light Water Reactors, was investigated. A model simulating the two-phase flow and heat transfer on the reactor vessel outer surface quantified the increase in decay power that can be removed using a nanofluid, predicting that the use of a nanofluid will allow a stable operating power ~40% greater than the power allowable using water to be achieved, while holding the Minimum Departure from Nucleate Boiling Ratio (MDNBR) constant. A nanofluid injection system that would take advantage of the enhanced CHF properties of the nanofluid in order to provide a higher safety margin than the current IVR strategy or, for given margin, enable IVR at higher core power, is proposed. A risk-informed analysis has revealed that this injection system has a reasonably high success probability of 0.99, comparable to the success probability without the injection system. Potential regulatory, environmental, and health risk issues were analyzed, and it was concluded that the current regulatory regimes are adequate for ensuring that the implementation of nanofluids in IVR will not endanger public health and safety. However...

A methodology to assess proliferation resistance of advanced nuclear energy systems is investigated. The framework, based on Multi-Attribute Utility Theory (MAUT), is envisioned for use within early-stage fuel cycle simulations. Method assumptions and structure are explained, and reference technology cases are presented to test the model. Eleven metrics are presented to evaluate the proliferation resistance of once-through, COmbined Non-Fertile and Uranium (CONFU), Mixed-Oxide (MOX), and Advanced Burner Reactor (ABR) fuel cycles. The metrics are roughly categorized in three groups: material characteristics, material handling characteristics, and "inherent" facility characteristics. Each metric is associated with its own utility function, and is weighted according to the proliferation threat of interest. Results suggest that transportation steps are less proliferation-resistant than stationary facilities, and that the ABR fuel cycle employing reactors with low conversion ratios are particularly safe. Nearly all steps of the fuel cycles analyzed are more proliferation resistant to a terrorist threat than to a host nation threat (which has more resources to devote toward proliferation activities). The open light water reactor (LWR) and MOX cycles appear to be the most vulnerable of all cycles analyzed. CONFU proliferation resistance is similar to that of the ABR with conversion ratios 0.5 and 1.0; these are all approximately in between the values ascribed to LWR/MOX (at the low end) and ABR with conversion ratio zero (with the highest proliferation resistance). Preliminary studies were conducted to determine the sensitivity of the results to weighting function structure and values. Several different weighting functions were applied to the utility values calculated for the once-through and CONFU fuel cycles. The tests showed very little change in the ultimate trends and conclusions drawn from each fuel cycle calculation. These conclusions...

The practice of brachytherapy and brachytherapy dosimetry was investigated with emphasis on evaluations of dose distributions and shielding considerations for both photon- and neutron-emitting radionuclides. Monte Carlo simulation methods were employed to calculate dose distributions for virtual and commercial brachytherapy sources. Radionuclides studied were 103Pd, 1251, 131Cs, 137Cs, 169b, 192Ir, and 252Cf. 252Cf sources also emit neutrons from spontaneous fission. The brachytherapy dosimetry protocol recommended by the American Association of Physicists in Medicine was followed and evaluated for conditions of partial scatter (non-infinite media) and material inhomogeneities, both commonly encountered in brachytherapy treatment. Furthermore, energy-dependent characteristics of dosimetry parameters were evaluated and reference calculations performed for virtual photon and neutron sources. These findings were applied to three clinical brachytherapy cases: eye plaques using 103Pd, 125I, and 131Cs; high-dose rate 252Cf treatment; and, 2 Cf plaques for superficial lesions. For eye plaques, material heterogeneities were significant for each radionuclide with dose reduction at 5 mm of 18%, 11%, and 10% for P03pd, 125I, and 131Cs, respectively. For a proposed highdose rate 252Cf source (5mm length)...

The unrelenting increase in oil use by the U.S. light-duty vehicle (LDV) fleet presents an extremely challenging energy and environmental problem. A variety of propulsion technologies and fuels have the promise to reduce petroleum use and greenhouse gas (GHG) emissions from motor vehicles. Previous work in this domain has compared individual vehicle or fuel alternatives. The aim of this research was to deepen the understanding of the likely scale and timing of the fleet-wide impact of emerging technologies. A model of the light-duty vehicle fleet showed that fuel consumption of mainstream gasoline internal combustion engine (ICE) technology vehicles will determine the trajectory of fleet fuel use and GHG emissions over the next two decades. Using vehicle simulations and historical data, the trade-off between vehicle performance, size and fuel consumption was quantified. It was shown that up to 26 percent reduction in future LDV fuel use is possible with mainstream gasoline ICE vehicles alone if emphasis of vehicle technology is on reducing fuel consumption rather than improving performance. Addressing this vehicle performance-size-fuel consumption trade-off should be the priority for policymakers. By considering both supply and demand side constraints on building up vehicle production rates...

The international diffusion of technology presents an opportunity for developing economies distant from the world technological frontier to reduce their income gap relative to advanced economies. It is therefore crucial to understand why, when faced with similar technological alternatives different firms in different countries choose to adopt different vintages of capital. This paper examines technology adoption across firms in Eastern Europe and Central Asia. The findings show that access to complementary inputs - managerial capacity, skilled labor, finance, and good infrastructure - and to international knowledge - through foreign direct investment or exports - is an important correlate of technology adoption. The link between market incentives and technology adoption is more nuanced. Although consumer pressure results in technology adoption, competitor pressure does not, suggesting that only firms with rents are able to adopt technology given substantial resource constraints. Privatized firms exhibit better technology adoption outcomes but only when a clear private owner with a profit incentive is present. Better governance is associated with technology adoption only in the countries that joined the European Union in 2004. Future increases in technology adoption by firms in the region will require complementary reforms of the investment climate.

This thesis characterizes the important role of US ethnic scientists and entrepreneurs for international technology diffusion. Chapter 1 studies the transfer of tacit knowledge regarding new innovations through ethnic scientific communities in the US and their ties to their home countries. US ethnic research communities are quantified by applying an ethnic-name database to individual patent records. International patent citations confirm knowledge diffuses through ethnic networks, and manufacturing output in foreign countries increases with an elasticity of approximately 0.3 to stronger scientific integration with the US frontier. To address reverse-causality concerns, reduced-form specifications exploit exogenous changes in US immigration quotas. Consistent with a model of sector reallocation, output growth in less developed economies is facilitated by employment gains, while more advanced economies experience sharper increases in labor productivity. The findings suggest tacit knowledge channels partly shape the effective technology frontiers of developing economies. Chapter 2 further exploits this heterogeneous technology diffusion through ethnic networks to test the importance of Ricardian technology differences for international trade. Panel regressions find technology growth increases manufacturing exports.; (cont.) To establish a causal relationship between technology and trade...

The accumulation of transuranic inventories in spent nuclear fuel depends on both deployment of advanced reactors that can be loaded with recycled transuranics (TRU), and on availability of the facilities that separate and reprocess spent fuel. Three recycling strategies are explored in this study: (1) Recycling in thermal Light 'Water Reactors (LWR) using CONFU technology (COmbined Non-Fertile and UO2 fuel), (2) recycling of TRU in fast cores of Actinide Burner Reactors (ABR), and (3) recycling of TRU with UO2 in self-sustaining Gas-cooled Fast Reactors (GFR). Choosing one fuel cycle strategy over the others involves trade-offs that need to be quantified. The CONFU, ABR, and GFR strategies differ from each other in terms of TRU loading in the reactor, net TRU incineration, capacities of recycling facilities needed, technology option availability, and flexibility. The CONFU and GFR are assumed to achieve zero net TRU incineration, while the ABR is a net consumer of TRU. The TRU loading is greatest in GFR and lowest in CONFU. While both CONFU and ABR require separation (of TRU from U) and reprocessing (recycling of TRUs from fertile-free fuel), the GFR is designed to, in equilibrium, recycle TRU+U after extraction of fission products only. It is assumed that thermal recycling is available in the short-term (2015)...

During the last two decades, traffic congestion in the U.S. has increased from 30% to 67% of peak period travel. Further, current research shows that measures taken within transportation systems, such as adding capacity, improving operations and managing demand, are not enough to keep congestion from growing worse. With the worsening traffic, the vehicle's fuel consumption and pollutant emissions will inevitably increase. As such, this thesis aims to quantitatively evaluate the energy and environmental impacts of worsening traffic on individual vehicles and the U.S. light-duty vehicle fleet, as well as to design feasible measures beyond transportation systems to offset theses impacts. The fuel consumption and emissions of different vehicle types under different driving situations provide the basis for analyzing the energy and environmental impacts of worsening traffic. This thesis defines the concept of "driving segments" to represent all possible driving situations which consist of vehicle speed, operation patterns and road types. For each vehicle type, its fuel consumption and emissions in different "driving segments" can be developed into a matrix by ADVISOR 2004, the vehicle simulation tool. Combining the "driving segments" vehicle performance matrices with the model for traffic congestion...

Traffic congestion is becoming a serious problem. As a solution, advanced traveler information systems (ATIS) mitigate traffic congestion by providing real-time traffic information to travelers. ATIS includes various applications such as radio traffic reporting services and websites. Among those, this thesis focuses on more advanced real-time traffic information systems, which provide sophisticated traffic information to drivers via in-vehicle devices such as car navigation systems: we call them ATISN (advanced traveler information systems for vehicles). ATISN has a high potential to mitigate traffic congestion and improve travel for individual drivers. However, in some countries, ATISN has not been accepted well by drivers. To improve this situation, three questions motivate this study: (1) why does ATISN in some parts of the world have more penetration than in others, (2) what can be done to increase the penetration of ATISN, and (3) what kinds of strategic alliances among stakeholders can help to make better ATISNs. This thesis compares three countries, the U.S., Germany, and Japan, by a qualitative analysis of the system dynamics methodology to clarify reasons which have been causing differences in the penetration.; (cont.) Additionally...

In today's world of advanced technology and global reach, one company cannot necessarily make a significant technological innovation. A company that pursues a technological advantage needs to manage global collaboration or competition appropriately. Over the years, the "standardization" of technology has been one of the major strategies with which to encourage technological innovation and acquire a competitive advantage. However, a standardized technology does not necessarily contribute to creating a competitive advantage, and the "differentiation" of technology sometimes provides a better competitive advantage than standardization can. This thesis focuses on the strategic differences between the "standardization" and "differentiation" of a technology. The purpose is to gain insight into standardization and differentiation, looking them as drivers of R&D activities in a company pursuing technical competence. The thesis suggests advantages and disadvantages of each strategy and analyzes circumstances that affect strategic differences. The first part of the thesis establishes the fact that the strategic difference has a less impact on business activities and commercial success than on R&D.; (cont.) The second part clarifies the impact of the difference on R&D activities...
