Crsm 1 2009 Andrea Lorelli Etsi Towards Standardization Of Cognitive Radioimec.archive
This document discusses ETSI's work towards standardizing cognitive radio technologies. It provides background on ETSI as a standards organization and describes its RRS Technical Committee, which has four working groups studying different aspects of cognitive radio standardization. The working groups have produced several technical reports on topics like cognitive radio system concepts, spectrum usage, radio architectures, and applying cognitive radio to public safety networks. The document concludes that standardization is needed for cognitive radio to allow cooperation between stakeholders and improve spectrum efficiency, network capacity, and access to services.
There are three main types of conditional patterns in conditional sentences: Pattern A is used for probable conditions, Pattern B is used for improbable conditions, and Pattern C is used for imaginary conditions. Pattern A uses present tense in the if-clause and future tense in the main clause. Pattern B uses past tense in the if-clause and would/should + verb in the main clause. Pattern C uses past perfect in the if-clause and perfect conditional ("would have" + past participle) in the main clause.

The document questions whether the internet should be viewed as a homogeneous global news medium. It finds that while the boundaries between traditional media are blurring through convergence, different types of online media like newspapers and blogs still have distinct characteristics. It also finds that while people have access to global news online, they primarily use domestic news sources and display a "digital divide in use." Specifically, a survey found college students in Belgium have very low usage rates of foreign online news media.

Galàxies actives
1. Definició
Són galàxies que emeten grans quantitats d'energia des del seu nucli. D'una
galàxia normal es registra una emissió d'energia corresponent a la que emeten
totes les estrelles, pols i gas estel.lar d'aquesta galàxia, però una galàxia activa
sobrepassa la quantitat d'energia esperada.
Característiques
Una característica molt important d'una galàxia activa és que el seu espectre no
depèn de la temperatura. Per calcular la temperatura d'una estrella s'analitza el
seu espectre (la longitud d'ona amb més intensitat indica la temperatura d'aquesta
estrella) ja que la temperatura influeix en ell, però en les galàxies actives no
influeix. Emeten energia provinent de l'espectre electromagnètic, més
específicament de raigs X, gamma, ultraviolada, infraroig i ones de ràdio. Es poden
classificar en: tipus Seyfert, quàsar, radiogalàxia, blazer i objecte extremadament
vermell. Els científics creuen que alguns dels tipus de galàxies actives tenen
diferents aparences pel fet que se les veuen en diferents adreces, però en realitat
pertanyen a una mateixa classe de galàxia activa.
Les galàxies actives presenten quatre principals característiques:
Molt compactes, és a dir, tenen alta densitat.
Alta lluminositat (bilions de vegades més lluminosos que el Sol).
Emissió constant d'energia que pertany a l'espectre electromagnètic.
Tenen espectres d'emissió.
Model d'una galàxia activa
Si dins d'una galàxia hi ha un forat negre, aquest començarà a atraure les
partícules de gas i pols que es troben en les seves proximitats. Aquestes
partícules formen un disc d'acreció al forat negre. Recordem que si una
partícula es troba aïllada, gira al voltant del punt de massa indefinidament, però
al trobar-junta a altres partícules, el continu xoc entre aquestes produeix una
disminució de velocitat el que comporta que sigui atret per aquest punt de
massa i caigui descrivint una espiral. Com a conseqüència de la fricció, la
temperatura del gas augmenta considerablement, de fet, alguns astrònoms
especulen que la temperatura del disc d'acreció en les proximitats del forat
negre sobrepassa els diversos milions de graus. El gas està en estat de plasma
i transforma la seva energia gravitacional en calor a causa del frenat de la seva
velocitat, emetent així radiacions corresponents als raigs-X i gamma.
2. Quan el forat negre no té més matèria propera de consumir, es torna
inactiu convertint la galàxia activa en una normal. Això últim es basa en
alguns forats negres observats que es troben en un estat inactiu, com el
que està al centre de la Via Làctia.
3. Estructura
Les galàxies actives estan formades per un nucli, l'halo, el disc d'acreció,
els jets, una protuberància que envolta el nucli i els lòbuls emissors
d'ones de ràdio.
Els jets són una part molt important de la galàxia activa, visualment són
línies rectes amb diferents sentits. Són electrons expulsats de la
protuberància i quan xoquen amb el gas que envolta la galàxia,
s'escampen formant lòbuls, aquests continuen els jets però en una franja
molt més ampla i Disform donant-li al conjunt una aparença similar al
fong que es forma amb l'explosió de una bomba atòmica, els lòbuls
poden arribar a assolir milions d'anys-llum de distància des del nucli de
la galàxia.
Per últim cal comentar la notícia del 13 de maig de 2010 on el que s’ha
descobert un forat negre enorme en una galàxia activa. La descubridora ha
estat una tal Marianne Heida . Aquest forat negre és tan gran que pesa mil
milions més vegades que el Sol. Això si el que li pasa a aquest forat negre
esque està sent expulsat per la galàxia a gran velocitat. Els astrònoms
diuen que l'expulsió pot prendre lloc sota condicions especials quan dos
forats negres es fonen. El procés d'unió crea un nou forat negre i models
d'ordinador suggereixen que és disparat a gran velocitat, depenent de la
direcció i velocitat a la qual els dos forats negres giraven abans de la
col.lisió.
