Eighth National Garrett Morgan Symposium on Sustainable Transportation, Report MTI 08-03

On April 1, 2008, the Mineta Transportation Institute at San José State University hosted a videoconference that brought together experts in surface transportation and students from middle and high schools across the nation to discuss the importance of sustainable transportation. The goal was to introduce students to future career opportunities in transportation and to inspire them to take the high school and college courses that will prepare them for professional careers. Students from California, Maryland and Virginia participated in the 2008 symposium, during which they heard opening remarks from Vice Admiral Thomas J. Barrett, Deputy Secretary of the U.S. Department of Transportation. Five teams of students presented their ideas on sustainable transportation alternatives for the future. These included a magnetic hover bus that can traverse both land and water, a plug-in electric-biodiesel-solar hybrid car, applications of the Stirling engine, a solar-hydropower bus, and an electric car with back-up power from solar panels and an internal windmill. The formal presentations were followed by a moderated question-and-answer session in which student teams questioned each other about their projects and sought the advice of experts about preparation for transportation careers and the critical issues they will face in the future. This publication is an edited summary of the April 2008 event, named in honor of Garrett A. Morgan, a black American inventor honored by Congress for his contributions to transportation and public safety

The program includes a keynote address, invited technical papers, and selected technical presentations to provide a broad forum for the discussion of a number of important issues in the field of mass storage systems. Topics include magnetic disk and tape technologies, optical disk and tape, software storage and file management systems, and experiences with the use of a large, distributed storage system. The technical presentations describe integrated mass storage systems that are expected to be available commercially.

Software Patents on Both Sides of the Atlantic, 23 J. Marshall J. Computer & Info. L. 815 (2005)

This comment addresses and analyzes the state of software patentability in the United States (“U.S.”) and European Union (“E.U.”). This comment discusses policies that drive changes and developments in patent law, the technical background of software, and the non-patent intellectual property protection for software. The comment further addresses the judicial precedent and the situation surrounding software patents in the U.S. and the legal situation in the E.U., including proposed changes in the Software Patent Directive. Finally, the article discusses common criticisms of current U.S. policies on software patentability by exposing the problems created by these policies and suggests corrective policies in the future

Use of Time-Frequency Analysis and Neural Networks for Mode Identification in a Wireless Software-Defined Radio Approach

The use of time-frequency distributions is proposed as a nonlinear signal processing technique that is combined with a pattern recognition approach to identify superimposed transmission modes in a reconfigurable wireless terminal based on software-defined radio techniques. In particular, a software-defined radio receiver is described aiming at the identification of two coexistent communication modes: frequency hopping code division multiple access and direct sequence code division multiple access. As a case study, two standards, based on the previous modes and operating in the same band (industrial, scientific, and medical), are considered: IEEE WLAN 802.11b (direct sequence) and Bluetooth (frequency hopping). Neural classifiers are used to obtain identification results. A comparison between two different neural classifiers is made in terms of relative error frequency

Authoring collaborative projects: a study of intellectual property and free and open source software (FOSS) licensing schemes from a relational contract perspective

The emergence of free and open source software (FOSS) has posed many challenges to the mainstream proprietary software production model. This dissertation endeavours to address these challenges through tackling the following legal problem: how does FOSS licensing articulate a legal language of software freedom in support of large-scale collaboration among FOSS programmers who have to face a rather hostile legal environment underlined by a dominant ideology of possessive individualism? I approach this problem from three aspects. The first aspect examines the unique historical context from which FOSS licensing has emerged. It focuses on the most prominent “copyleft” licence—GNU General Public Licence—which has been shaped by the tension between the MIT-style hacker custom and intellectual property law since the 1980s. The second aspect tackles the legal mechanism of FOSS licences, which seems not dissimilar from other non-negotiated standard-form contracts. My analysis shows that FOSS licences do not fit well with the neoclassical contract model that has dominated software licensing jurisprudence so far. I therefore call for replacing the neoclassical approach with Ian Macneil’s Relational Contract Theory, which has remained conspicuously absent in the software licensing literature. The third aspect explores FOSS programmers’ authorship as manifested in FOSS licensing. It argues that the success of a FOSS project does not merely depend on the virtuosity of individual programmers in isolation. More importantly, a core team of lead programmers’ efforts are essential to channel individual authors’ virtuosity into a coherent work of collective authorship, which can deserve credit for the project as a whole. The study of these three aspects together aims to create a synergy to show that it is possible to graft a few collaborative elements onto the existing legal system—underpinned by a neoliberal ideology assuming that human beings are selfish utility-maximising agents—through carefully crafted licensing schemes

The Need of Multidisciplinary Approaches and Engineering Tools for the Development and Implementation of the Smart City Paradigm

This paper is motivated by the concept that the successful, effective, and sustainable implementation of the smart city paradigm requires a close cooperation among researchers with different, complementary interests and, in most cases, a multidisciplinary approach. It first briefly discusses how such a multidisciplinary methodology, transversal to various disciplines such as architecture, computer science, civil engineering, electrical, electronic and telecommunication engineering, social science and behavioral science, etc., can be successfully employed for the development of suitable modeling tools and real solutions of such sociotechnical systems. Then, the paper presents some pilot projects accomplished by the authors within the framework of some major European Union (EU) and national research programs, also involving the Bologna municipality and some of the key players of the smart city industry. Each project, characterized by different and complementary approaches/modeling tools, is illustrated along with the relevant contextualization and the advancements with respect to the state of the art

Relativistic GWGW+BSE study of the optical properties of Ruddlesden-Popper iridates

We study the optical properties of the Ruddlesden-Popper series of iridates Sr$_{n+1}$Ir$_n$O$_{3n+1}$ ($n$=1, 2 and $\infty$) by solving the Bethe-Salpeter equation (BSE), where the quasiparticle (QP) energies and screened interactions $W$ are obtained by the $GW$ approximation including spin-orbit coupling. The computed optical conductivity spectra show strong excitonic effects and reproduce very well the experimentally observed double-peak structure, in particular for the spin-orbital Mott insulators Sr$_2$IrO$_4$ and Sr$_3$Ir$_2$O$_7$. However, $GW$ does not account well for the correlated metallic state of SrIrO$_3$ owing to a much too small band renormalization, and this affects the overall quality of the optical conductivity. Our analysis describes well the progressive redshift of the main optical peaks as a function of dimensionality ($n$), which is correlated with the gradual decrease of the electronic correlation (quantified by the constrained random phase approximation) towards the metallic $n=\infty$ limit. We have also assessed the quality of a computationally cheaper BSE approach that is based on a model dielectric function and conducted on top of DFT+$U$ one-electron energies. Unfortunately, this model BSE approach does not accurately reproduce the outcome of the full $GW$+BSE method and leads to larger deviations to the measured spectra.Comment: 13 pages, 8 figure
