National nitrogen budget for Denmark (excel-file 125 kB)

The data describe the flows of nitrogen between different pools and economic sectors within Denmark. The data are stored in an Excel spreadsheet that is divided into a number of worksheets. The National worksheet contains the national flows of nitrogen for the years 1990 to 2010 (note that for some flows, the data series is not complete for all years). These data underlie the national nitrogen flow figures in the main text of the paper. The remaining worksheets contain the data that underlie the figures presented in the detailed description of nitrogen flows between pools/sectors, that is in the Supplementary Material associated with the paper.

Scalable Raid Storage Based on the Structure of Multimedia File.

In professional video production, users have to access to huge multimedia files simultaneously in an error-free environment, this restriction force the use of expensive disk architectures for video servers. Previous researches proposed different RAID systems for each specific task (ingest, editing, file, play-out, etc.). Video production companies have to acquire different servers with different RAIDs systems in order to support each task in the production workflow. The solution has multiples disadvantages, duplicated material in several RAIDs, duplicated material for different qualities, transfer and transcoding processes, etc. In this work, an architecture for video servers based on the spreading of JPEG200 data in different RAIDs is presented, each individual part of the data structure goes to a specific RAID type depending on the effect that produces the data on the overall image quality, the method provide a redundancy correlated with the data rank. The global storage can be used in all the different tasks of the production workflow saving disk space, redundant files and transfers procedures.

Hybrid Contribution of JPEG200 Video Files for Professional Production Centers Reliability and Non-Reliability Transmission File Based in Image Quality Needed

ATM, SDH or satellite have been used in the last century as the contribution network of Broadcasters. However the attractive price of IP networks is changing the infrastructure of these networks in the last decade. Nowadays, IP networks are widely used, but their characteristics do not offer the level of performance required to carry high quality video under certain circumstances. Data transmission is always subject to errors on line. In the case of streaming, correction is attempted at destination, while on transfer of files, retransmissions of information are conducted and a reliable copy of the file is obtained. In the latter case, reception time is penalized because of the low priority this type of traffic on the networks usually has. While in streaming, image quality is adapted to line speed, and line errors result in a decrease of quality at destination, in the file copy the difference between coding speed vs line speed and errors in transmission are reflected in an increase of transmission time. The way news or audiovisual programs are transferred from a remote office to the production centre depends on the time window and the type of line available; in many cases, it must be done in real time (streaming), with the resulting image degradation. The main purpose of this work is the workflow optimization and the image quality maximization, for that reason a transmission model for multimedia files adapted to JPEG2000, is described based on the combination of advantages of file transmission and those of streaming transmission, putting aside the disadvantages that these models have. The method is based on two patents and consists of the safe transfer of the headers and data considered to be vital for reproduction. Aside, the rest of the data is sent by streaming, being able to carry out recuperation operations and error concealment. Using this model, image quality is maximized according to the time window. In this paper, we will first give a briefest overview of the broadcasters requirements and the solutions with IP networks. We will then focus on a different solution for video file transfer. We will take the example of a broadcast center with mobile units (unidirectional video link) and regional headends (bidirectional link), and we will also present a video file transfer file method that satisfies the broadcaster requirements.

Diplomatic Spin: EU3+3 talks on Iran’s nuclear file. CEPS Commentary, 21 November 2014

The Joint Plan of Action agreed upon with Iran on 24 November 2013 gave negotiators one year to forge a comprehensive agreement that restricts the country’s ability to militarise its nuclear programme. That deadline will lapse in the next few days and diplomats involved in the talks have been trying to rein in expectations that a deal will be struck on time. Satisfying domestic constituencies in Iran and the US is what makes the politics of dealing with the nuclear file so much harder than the physics of slowing down the nuclear programme. Any future deal will have to stand on its own merits, enabling Iran and the EU3+3 to cooperate on the other geopolitical challenges they face. Both parties should therefore balance their demands with what they can realistically offer and make concessions to reach a compromise. The author of this CEPS Commentary argues that if no deal is reached on November 24th, then diplomacy should be allowed to keep on spinning for a few more months.

Sviluppo di un'applicazione di sincronizzazione file per reti challenged

Questa tesi si pone l'obiettivo di implementare in ambiente Linux un'applicazione di sincronizzazione, chiamata DTNbox, che permetta lo scambio di file tra due nodi di una rete classificabile come Delay-/Disruption-Tolerant Network (DTN), ossia una rete in cui a causa di ritardi, interruzioni, partizionamento, non sia possibile utilizzare l'usuale architettura di rete TCP/IP. E' evidente che i problemi menzionati rendono estremamente più complessa la sincronizzazione fra cartelle rispetto ad Internet, da cui le peculiarità di DTNbox rispetto ad altre applicazioni in rete visto che, ad esempio, non è possibile la sincronizzazione tramite un nodo centrale, come in Dropbox e similari, ma occorre basarsi su comunicazioni peer-to-peer. L'oggetto della mia tesi si è quindi sviluppato principalmente su tre direzioni: • Implementare, utilizzando il linguaggio di programmazione C, le funzionalità previste dal nuovo progetto per Linux • Integrarne e modificarne le parti ritenute carenti, man mano che i test parziali ne hanno mostrato la necessità • Testarne il suo corretto funzionamento Si è deciso pertanto di dare precedenza alla scrittura delle parti fondamentali del programma quali i moduli di controllo, la struttura e gestione del database e lo scambio di messaggi tra due nodi appartenenti ad una rete DTN per poter arrivare ad una prima versione funzionante del programma stesso, in modo che eventuali future tesi possano concentrarsi sullo sviluppo di una interfaccia grafica e sull'aggiunta di nuovi comandi e funzionalità accessorie. Il programma realizzato è stato poi testato su macchine virtuali grazie all'uso dello strumento Virtualbricks.
