Stop and Wait Link Utilization and Throughput -


consider stop-and-wait data link protocol operating on link parameters follows: tprop = d/v d distance between transmitter , receiver in meters , v signal propagation speed in meters per second, , tf = l/r l frame length in bits, , r link transmission rate in bits per second. ignoring tack , tproc , required answer following questions:

a) plot link utilization function of link transmission, u(r) r ϵ [0,∞).

b) find quantities lim 'r→ ∞' u(r) , lim 'r→ 0+' u(r).

c) plot link throughput in bit per second, throbps(r) r ϵ [0,∞).

d) plot link throughput in frames per second, throfps(r) r ϵ [0,∞).

e) find quantities lim 'r→ ∞' throfps(r) , lim 'r→ 0+' throfps(r).

the labels plots computed quantities should in terms of link parameters.

php - SPIP: From Tag directly to an article -

i work spip , plugin called tagsphere works fine tags in spip. have tag groupe put 1 article tag. when click on tag in tagsphere send me before menu can see articles linked tag. want send me directly article without see tag menu before. here code model of thagsphere: <div id="tagsphere-#env{id_article}"> <ul> <boucle_mot(mots){id_groupe ?}> <li>[<a href="#url_mot">(#titre)</a>]</li> </boucle_mot> </ul> </div> anybody idea? if want skip tag page, have link directly article. <b_article> block prevents display tag if no article linked. <div id="tagsphere-#env{id_article}"> <ul> <boucle_mot(mots){id_groupe ?}> <b_article> <li> <a<boucle_article(articles){...

ruby on rails - In a controller spec, how to find a specific tag in the generated view? -

i know integration tests preferred need ran in controller test, i'm testing gem injecting html code in view, xhr can't run in feature spec (if can, please explain me how :) ) so rspec controller tests can assert selector present (with capybara) : response.body.should have_selector('#foobar') has_selector? call all method capybara find selector. what want last child of body , assert id in particular. afaik it's not possible have_selector. what : all('body:first-child').first.id.should == '#foobar' however, capybara dsl, defined (more or less): def all(*args) page.all(*args) end and page empty unless use visit it's integrations specs. how can use capybara all method inside rspec controller test ? i can't test right after googling seems trick def page capybara::node::simple.new(response.body) end source
