Design, Implementation and Experimental Evaluation of a Wireless MAC Processor over commercial WIFI cards

2014

In this thesis we face the problem of wireless network programmability as a solution for coping with context-dependent optimizations, moving from one-for-all standard solutions to the concept of programmable wireless interfaces. Although the wireless research and academic community has proposed interesting platforms (e.g. based on Software Defined Radio) for pushing forward dynamic reprogrammability of devices, we argue that it is important to identify a tradeoff between programmability space and usability of the programmable interface. In this direction, we introduce the concept of Wireless MAC Processor and developed a running prototype over an ultra-cheap wireless card. Wireless MAC proc…

Motivisk symbolikk i Bach's tonespråk

2006

Masteroppgave i utøvende musikk 2006 - Høgskolen i Agder, Kristiansand Motivisk symbolikk i Bach’s tonespråk er emnet for min mastergradsoppgave. Emnet sorterer under fordypningsområdet Interpretasjonsstudier i mastergradsstudiet i utøvende musikk, ved Høgskolen i Agder, 2006. Oppgaven består av 81 sider og inneholder bl.a. noteeksempler og en CD innspilling av to preludier og to fuger av J.S. Bach. Målet med å skrive oppgaven har vært å vise at det finnes et religiøst innhold i Bach’s instrumental-komposisjoner, som vanligvis betraktes som ”abstrakt” musikk. Den skriftlige delen består av tre deler: I den første delen har jeg drøftet et religiøst innhold i forskjellige kunstretninger i bar…

Small Employers, Large Employers and the Skill Premium

2015

I document the comovement of the skill premium with the differential employer size wage premium between high- and low-skill workers in U.S. manufacturing during the postwar era. For the baseline specification, i.e., establishments with at least 500 employees categorized as large employers and non-production workers as high-skilled, I obtain a correlation coefficient of 0.87. Exploiting variations across subindustries while controlling for other potentially relevant factors, I estimate that an increase by ten log-points in the differential size premium is associated with an increase in the skill premium by three log-points.

Universal charts for optical difference frequency generation in the terahertz domain

2010

We present a universal and rigorous approach to study difference frequency generation in the terahertz domain, keeping the number of degrees of freedom to a minimum, through the definition of a suitable figure of merit. The proposed method relies on suitably normalized charts, that enable to predict the optical-to-terahertz conversion efficiency of any system based on wave propagation in quadratic nonlinear materials. The predictions of our approach are found to be in good agreement with the best experimental results reported to date, enabling also to estimate the d22 nonlinear coefficient of high quality GaSe.

Structure of longitudinal chromomagnetic fields in high energy collisions

2014

We compute expectation values of spatial Wilson loops in the forward light cone of high-energy collisions. We consider ensembles of gauge field configurations generated from a classical Gaussian effective action as well as solutions of high-energy renormalization group evolution with fixed and running coupling. The initial fields correspond to a color field condensate exhibiting domain-like structure over distance scales of order the saturation scale. At later times universal scaling emerges at large distances for all ensembles, with a nontrivial critical exponent. Finally, we compare the results for the Wilson loop to the two-point correlator of magnetic fields.

Network Reconfiguration Suitability for Scientific Applications

2008

This paper analyzes the communication pattern of several scientific applications and how they can make profit of network reconfiguration in order to adapt network topology to the communication needs so that total execution time is reduced. By using an analysis methodology based on real application executions, we study the variation of the required communication bandwidth with time and also the global interprocedural communication patterns. Results show that required bandwidth between each pair of processes does not significantly fluctuates, leading to a constant use of the links and therefore discouraging dynamic reconfigurations of the network during execution time. Nevertheless, the group…

La cultura ci salverà? Processi di touristification a base culturale nel centro storico di Palermo

2023

Negli ultimi tre decenni la cultura ha avuto un ruolo chiave nella costruzione delle politiche urbane, divenendo uno strumento decisivo nella definizione delle strategie di sviluppo economico e nell’accesso alla competizione globale che caratterizzano l’attuale regime di neoliberismo urbano (Miles e Paddison 2005). Anche nel sud Europa la cosiddetta rigenerazione a base culturale ha rappresentato e continua ancora oggi a rappresentare una vera e propria ortodossia urbana, che trova nel turismo tanto una ragione di esistenza quanto un campo di attuazione. In particolare, negli ultimi anni i centri storici di molte città sudeuropee sono stati oggetto di trasformazioni profonde in cui pratiche…

«Nozze» napoletane. «La serva onorata» di Giambattista Lorenzi e Nicolò Piccinni (1792)

2012

Nel 1792 il teatro napoletano dei Fiorentini ospitò la prima rappresentazione di una nuova opera comica di Giambattista Lorenzi e Niccolò Piccinni: «La serva onorata». Il libretto era in realtà una libera rielaborazione delle «Nozze di Figaro» di Da Ponte per Mozart. Il saggio avanza alcune ipotesi circa l'arrivo del testo nella capitale meridionale e procede poi a un dettagliato esame delle manipolazioni subite dal modello viennese, che risulta omologato alle convenzioni estetiche e produttive locali. Particolare attenzione viene riservata al ruolo degli interpreti napoletani, che con le proprie caratteristiche condizionano vistosamente il processo di adattamento. In chiusura vengono propo…
