    Intersystem soft handover for converged DVB-H and UMTS networks

    Get PDF
    Digital video broadcasting for handhelds (DVB-H) is the standard for broadcasting Internet Protocol (IP) data services to mobile portable devices. To provide interactive services for DVB-H, the Universal Mobile Telecommunications System (UMTS) can be used as a terrestrial interaction channel for the unidirectional DVB-H network. The converged DVB-H and UMTS network can be used to address the congestion problems due to the limited multimedia channel accesses of the UMTS network. In the converged network, intersystem soft handover between DVB-H and UMTS is needed for an optimum radio resource allocation, which reduces network operation cost while providing the required quality of service. This paper deals with the intersystem soft handover between DVB-H and UMTS in such a converged network. The converged network structure is presented. A novel soft handover scheme is proposed and evaluated. After considering the network operation cost, the performance tradeoff between the network quality of service and the network operation cost for the intersystem soft handover in the converged network is modeled using a stochastic tree and analyzed using a numerical simulation. The results show that the proposed algorithm is feasible and has the potential to be used for implementation in the real environment

    Factors Influencing Voting Results of Local Transportation Funding Initiatives with a Substantial Transit Component: Case Studies of Ballot Measures in Eleven Communities, MTI Report 01-17

    This publication is a follow-up study to MTI publication 00-01, Why Campaigns for Local Transportation Funding Initiatives Succeed or Fail: An Analysis of Four Communities and National Data. The earlier publication was case studies of four local ballot tax measures for transportation packages. The current study, Factors Influencing Voting Results of Local Transportation Funding Initiatives with a Substantial Rail Transit Component: Case Studies of Ballot Measures in Eleven communities, uses the same case study methodology as the prior study, and is expanded to 11 communities from the past four years. Some of the important conclusions identified by the study are as follows: 1) The combination of an energetic and credible opposition and a questionable reputation of the transit agency or transit system make it extremely difficult for a ballot measure to be successful; 2) When a community has no prior rail transit system, a comprehensive rail-only package is unlikely to be successful; 3)Without $1 million or more to spend on a combination of direct mail and television advertising it is difficult for proponents to be successful; 4) Developing a consensus transportation package depends on the specific details of the package and it is very difficult to generalize about the needed details; and 5) Under certain circumstances, voters do not appear to place significant importance on the existence or length of the expiration date of the tax used to fund the transportation package

    The Court, FCC and Internet Policy: Partly with

    The paper aims to explore the contour of internet regulation with a thread of Brand X , which navigates through constitutionalism, separation of powers, as well as business and economic or political implications enshrined behind it. An exemplary insight with the Korean case was adverted that could lead to the comparative perspective of internet law and regulation for the future research. The research was conducted by employing qualitative investigation, mainly relying on textual analysis and documentary examination. The outcome of research generally corroborates with our assumption that i) the increasing administrative state will variegate the traditional interplay of three branches, ii) expert bureaucracy stands at the core of policy shaping because of the necessary new concept of market and policy specialization, iii) the role of US government is not only pioneering, but also influential as a regulator, but comparatively with differing national jurisdictions if not a negligible implications on the international competition or even conflict

    Chasing Sustainability on the Net : International research on 69 journalistic pure players and their business models

    Get PDF
    This report outlines how online-based journalistic startups have created their economical locker in the evolving media ecology. The research introduces the ways that startups have found sustainability in the markets of ten countries. The work is based on 69 case studies from Europe, USA and Japan. The case analysis shows that business models can be divided into two groups. The storytelling-oriented business models are still prevalent in our findings. These are the online journalistic outlets that produce original content – news and stories for audiences. But the other group, service-oriented business models, seems to be growing. This group consists of sites that don’t try to monetize the journalistic content as such but rather focus on carving out new functionality. The project was able to identify several revenue sources: advertising, paying for content, affiliate marketing, donations, selling data or services, organizing events, freelancing and training or selling merchandise. Where it was hard to evidence entirely new revenue sources, it was however possible to find new ways in which revenue sources have been combined or reconfigured. The report also offers practical advice for those who are planning to start their own journalistic site

    Policy Issues in U.S. Transportation Public-Private Partnerships: Lessons from Australia, Research Report 09-15

    Get PDF
    In this report, the authors examine Australia’s experience with transportation public-private partnerships (PPPs) and the lessons that experience holds for the use of PPPs in the United States. Australia now has decades of experience in PPP use in transportation, and has used the approach to deliver billions of dollars in project value. Although this report explores a range of issues, the authors focus on four policy issues that have been salient in the United States: (1) how the risks inherent in PPP contracts should be distributed across public and private sector partners; (2) when and how to use non-compete (or compensation) clauses in PPP contracts; (3) how concerns about monopoly power are best addressed; and (4) the role and importance of concession length. The study examines those and other questions by surveying the relevant literature on PPP international use. The authors also interviewed 23 Australian PPP experts from the academic, public and private sectors, and distilled lessons from those interviews
