Frame delay and loss analysis for video transmission over time-correlated 802.11A/G channels
No full textThis paper presents simulation results for the transmission of unicast MAC frames over 802.11a/g. Fading channel models at various Doppler frequencies are developed to generate time- correlated SNR waveforms. These are then used together with a bit accurate MAC/PHY simulator to estimate the frame loss rate, the transmission delay, and the jitter for a steady flow of transmit frames. Time correlated channels are required to correctly simulate the bursty nature of packet loss in a wireless channel. The Doppler spread is shown to have a strong effect on the performance of the ARQ mechanism in the MAC layer. Delay is computed as the sum of the transmission delay and the accumulated queuing delay in the MAC buffer. Delay and frame loss are compared for time correlated and time uncorrelated fading channels. Compared to the slow fading case, in a fast fading channel fewer retransmissions are required and the end-to-end delay is significantly reduced. When channel conditions are poor the simulated delay and frame loss rate are seriously underestimated when time uncorrelated fading is assumed. To analyze the performance of video codecs, we show that a time correlated channel model must be combined with a dedicated 802.11a/g MAC/PHY simulation.This paper presents simulation results for the transmission of unicast MAC frames over 802.11a/g.

Materia-autore = Author-Matter
No full textThe etymology of the word author refers to an act of creation, an act of augmentation, from the Latin verb augere. Author instantiates creation, the expansion of the pre-existing. In 1967 Roland Barthes declared the death of the author in his famous essay to state once more that the crisis is that of the author as a single subjectivity and as a term that condenses prestige, undermined by the de-subjectivation strategies of automatism, fortuity and fragmentation of the historical avant-gardes, as well as by the machinic act and by the reproducibility of the second avant-gardes.
Fifty years after Barthes’ paradigmatic formula, this lack of authorship appears to be a successful brand. The ten- sions between the anomie of matter, the law that establishes authorship and the economy that makes the work pos- sible, invoke discordant perspectives. Artists make the self-destruction of their work the real work, and appeal is made for the demolition of architectures, whether by a recognised author or not, in order to re-design, or better still, re-claim the territory. Artificial intelligence consolidates its logics and its design by progressively shedding human ingenuity. The space of criticism becomes, finally, increasingly ephemeral. However, there is an acceptation of criti- cism that is, rather than an individual ‘signature’, an exploration and explanation of how design makes theory.
The binomial author-matter seeks to mark these tensions and contradictions: the featured term author is main- tained to underline the persistence of that prestigious subjectivity, at the very moment when the rhetoric of “mat- ter as an author” promises other forms of authorship

Intergovernmental equalization grants: some fundamental principles.
No full textPropositions related to intergovernmental equalization grants are always implicitly or explicitly derived from one model of government or another. The paper assumes that governments are competitive organisms. In such a frame of reference, equalization payments serve to insure that all the units in a decentralized governmental system have a chance to share in the benefits of competition. In other words, equalization payments are stabilization instruments. As such they will generally have an effect on the interpersonal distribution of income, but they are not motivated by that effect. The paper also argues that economic globalization increases the need for equalization grants.
Deliberation and journalism
No full textThe first chapter in 'International Journalism and Democracy' re-examines current ideas about the role of journalism in promoting democracy, introducing the concept of "deliberative journalism". 'Deliberation and Journalism' lists the ways in which journalists can assist deliberation and politics in communities around the world. The chapter defines deliberation as a specific form of conversation that precedes and promotes decision-making and action by members of a community. The author recognises the difficulty of engaging in deliberation in communities that are divided by different interests, identities, backgrounds, resources and needs. She provides examples of strategies that journalists can use to encourage inclusive and productive deliberation in the face of community diversity.\ud
\ud
The chapter introduces examples of types of deliberative journalism that have emerged around the globe. These include strategies that have been sometimes been labeled as public journalism, civic journalism, peace journalism, development journalism, citizen journalism, the street press, community journalism, environmental journalism, and social entrepreneurism. The chapter also includes models of journalism that have not yet been given any particular name. Although the book identifies problems surrounding the theory and practice of these forms of journalism, the author notes that this is to be expected. Most models of deliberative journalism are relatively new, with none being more than a few decades old. The author concludes that resolution of these problems will only occur incrementally
Il tempo perduto delle donne nei racconti di Adriana Bittel: Cum încărunţeste o blondă, Soi bun, Departe-n zare, spre Azuga
No full textIl contributo comprende la prima traduzione in italiano di tre racconti della scrittrice rumena Adriana Bittel, e un saggio sulle strategie narrative messe in atto da Bittel per descrivere lo spazio della socialità femminile nella Romania del periodo precedente al 1989The contribution consists of the translation into Italian of three short stories authored by the Romanian woman writer Adriana Bittel, entitled respectively, "How a Blond turns white", "Good Quality", “Far away in the horizon, towards Azuga”. Angela Tarantino, the author of the translation, adds to her work a presentation of Adriana Bittel and the narrative strategies used to describe the space of the women's sociality in Romania during the years previous to 198
A reference space for information management standards, tools and methodologies: the AIMS portal
No full textThe Agricultural Information Management Standards (AIMS) portal provides to information specialists in the agricultural domain good practices and methodologies on the management and dissemination of agricultural information by using widely accepted standards and methods. AIMS is a resource container where users can find experiences in applying semantic technologies and information standards to agricultural situations from related partnerships within (or for) the agricultural domain. AIMS is facilitated by the Food and Agricultural Organisation (FAO) of the United Nations with support from an external Consultative Group which provides feedback and guidance on technical improvements, outreach activities, new services, and strategic recommendations. This paper reviews the AIMS portal as a reference place for agricultural information management professionals with regard to standards, tools and methodologies for managing agricultural information and systems. It provides an overview of the AIMS portal content and the AIMS Community. Initiatives, such as the development and application of the AGROVOC Linked Open Data (LOD), Linked Open Data Enabled Bibliographic Recommendations (LODE-BD) or OpenAGRIS, are some of the products that are of interest to the agricultural information management community. The paper concludes with a sample re-enactment of how access to the AIMS portal may help an information management specialist to solve an archetype information management scenario
