    Cross - Layer Cross - Domain Adaptation of Mobile Video Services

    This paper deals with the analysis of user perceived visual quality for mobile-multimedia services. H.264/AVC is selected for low resolution video encoding, and a mobile UMTS network is considered for the access to services. First, from subjective tests results, the combined impact of different service - and radio network-level parameters...

    Reversible, Embedded and Highly Scalable Image Compression System

    In this paper a new method for low complexity image coding is presented, that permits different settings and great scalability in the generation of the final bit stream. This coding presents a continuous-tone still image compression system that groups loss and lossless compression making use of finite arithmetic reversible transforms....

    The Role Of The Terms Of Trade In The Trade Channel Of Transmission Of Oil Price Shocks

    This paper highlights the role of the terms of trade in the trade channel of propagation of oil price shocks both empirically and theoretically. Empirically, the author shows that oil price shocks have a large, persistent and statistically significant impact on the US terms of trade. Theoretically, the author adds...

    Fiscal Policy And Economic Stability: Does Pigs Stand For Procyclicality In Government

    The Financial Crisis has hit particularly hard countries like Ireland or Spain. Procyclical fiscal policy has contributed to a boom-bust cycle that undermined fiscal positions and deepened current account deficits during the boom. The authors set up an RBC model of a small open economy, following Mendoza (1991), and introduce...

    Prices And The Real Exchange Rate In Hong Kong: 1985-2006

    This paper seeks to quantify to the extent to which price dynamics in Hong Kong are due to the Balassa-Samuelson hypothesis. From 1985 to 1998, the CPI in Hong Kong increased spectacularly, yet there was dramatic deflation from 1998 to 2006. This dynamics was mainly driven by the price pattern...

    An Analysis Of The Main Drivers For ISO 9001 And Other Isomorphic Metastandards

    Research on the adoption of metastandards (e.g. ISO 9001, ISO 14001, OHSAS 18001, SA 8000) has used a variety of theoretical perspectives to identify the main driving forces or motivations. While the majority of existing studies on this subject are of an empirical character with little development of a theoretical...

    Unions, Monetary Shocks And The Labour Market Cycle

    This paper provides a new growth model by considering strategic behaviour in the supply of labour. Workers form a labour union with the aim of manipulating wages in their own benefit. The authors analyse the implications on labour market dynamics at business cycle frequencies of getting away from the price-taking...

    QoS-Oriented Admission Control in HSDPA Networks

    HSDPA defines a new High Speed Shared Channel (HS-DSCH) which allows for practical speeds up to 10 Mbps. Among all the changes introduced by HSDPA, the most prominent ones regarding QoS are the inclusion of "link adaptation", "Hybrid ARQ" and the quick "Scheduling" algorithms. In HSDPA the Radio Network Controller...

    Monopoly Price Discrimination And Demand Curvature

    This paper presents a general analysis of the effects of monopolistic third-degree price discrimination on welfare and output when all markets are served. Sufficient conditions -involving straightforward comparisons of the curvatures of the direct and inverse demand functions in the different markets - are presented for discrimination to have negative...

    Impact of the Video Slice Size on the Visual Quality for H.264 Over 3G UMTS Services

    The provision of video streaming services over mobile data accesses is emerging as a promising service for the current and future Internet. This paper focuses on the study of H.264- based video contents over a typical 3G UMTS connectivity. The performance of the service is finally determined by the combined...

    Study of the Impact of UMTS Best Effort Parameters on QoE of VoIP Services

    This paper evaluates the performance of VoIP services over mobile accesses, with special focus on currently deployed Best Effort UMTS networks. There are different configuration parameters that have a great impact on end users' perception of quality. This paper tries to help understanding the impact of those parameters, and how...

    Web QoE Evaluation in Multi-Agent Networks: Validation of ITU-T G.1030

    User's requirements have become a key factor for any Quality of Service (QoS) management model to succeed. The advent and rise of new broadband services and network architectures (Triple-Play-Services, NGN?) depends on the ability of providers to achieve user's expectations in these scenarios. For that reason, the overall end user's...
