Measuring competitiveness in Europe: resource allocation, granularity and trade. Bruegel Blueprint Series Volume XVIV, January 2016

One of the most important lessons learned during the 2008-09 financial crisis was that the informational toolbox on which policymakers base their decisions about competitiveness became outdated in terms of both data sources and data analysis. The toolbox is particularly outdated when it comes to tapping the potential of micro data for the analysis of competitiveness – a serious problem given that it is firms, rather than countries that compete on global markets.

Benefici del long route EGR sulla riduzione dei consumi: studio di fattibilità su motore diesel automobilistico

L'EGR (Exhaust Gas Recirculation) è una tecnica comunemente sfruttata per la riduzione delle emissioni. In questo studio sono stati investigati i benefici, in termini di fuel economy, prodotti dall'aggiunta di un circuito EGR long route su un motore diesel per applicazioni automobilistiche dotato di sistema short route. L'indagine è stata svolta su di un modello motore su software GT-Power, adeguatamente calibrato e validato sui dati da piano quotato. Simulazioni sono state svolte al fine di valutare gli effetti del solo LP-EGR sul motore, per poi considerare un funzionamento combinato dai due sistemi di ricircolo (dual loop). Le maggiori portate che per il sistema long route interessano la turbina determinano un incremento nelle contropressioni. Ciò ha portato a considerare la possibilità di modificare il sistema turbo. Il layout originario comprendeva una turbina a geometria fissa (FGT), a cui ne sono stati affiancati due ulteriori con turbina a geometria variabile (VGT). I risultati sono stati analizzati vincolando la produzione di inquinanti ai valori registrati nei punti di calibrazione relativi al layout originale del motore. Effettivo risparmio di combustibile non è stato riscontrato nell'allestimento con turbina FGT a causa delle elevate contropressioni, mentre con turbine VGT è stata registrata una effettiva fuel economy grazie al sistema LP-EGR senza alcun deterioramento nelle emissioni di NOx e PM. I benefici riscontrati con il LP-EGR sono da attribure ad un incremento del rendimento indicato dovuto alla riduzione delle perdite per scambio termico a seguito di una minore temperatura caratterizzante i gas ricircolati.

High-speed UDP Data Transmission with Multithreading and Automatic Resource Allocation

In this paper a utilization of the high data-rates channels by threading of sending and receiving is studied. As a communication technology evolves the higher speeds are used more and more in various applications. But generating traffic with Gbps data-rates also brings some complications. Especially if UDP protocol is used and it is necessary to avoid packet fragmentation, for example for high-speed reliable transport protocols based on UDP. For such situation the Ethernet network packet size has to correspond to standard 1500 bytes MTU[1], which is widely used in the Internet. System may not has enough capacity to send messages with necessary rate in a single-threaded mode. A possible solution is to use more threads. It can be efficient on widespread multicore systems. Also the fact that in real network non-constant data flow can be expected brings another object of study –- an automatic adaptation to the traffic which is changing during runtime. Cases investigated in this paper include adjusting number of threads to a given speed and keeping speed on a given rate when CPU gets heavily loaded by other processes while sending data.
