Display transparent image on axes (MATLAB) -

February 15, 2010

so have transparent image ( http://imgur.com/fyqslax ) want display on axes in matlab transperancy. this, used code below, works other transparent png images have: [a, map, alpha] = imread('fyqslax.png'); h = imshow(a, map) set(h, 'alphadata', alpha); this code however, not seem work image above. im guessing because has image being grayscale , having bitdepth of 1, resulting in map , alpha having nothing in (whereas other png transparent images have, have in map , alpha). if use this: a = imread('fyqslax.png'); h = imshow(a) a black background appears image should transparent. how display http://imgur.com/fyqslax transperancy on axes? edit: horchler's method worked; thanks!! if run imfinfo('fyqslax.png') , you'll see 'transparency' specified 'simple' , 'simpletransparencydata' set 0 ( false ). can't find documentation on this, think may indicate alpha channel has been compressed image data

networking - Why does the number of links not matter in the transmission time of circuit switching? -

February 15, 2010

i reading book networking, , says that, in circuit switching environment, number of links , switches signal has go through before getting destination not affect overall time takes signal received. on other hand, in packet switching scenario number of links , switches make difference. spent quite bit of time trying figure out, can't seem it. why that? to drastically over-simplify, circuit-switched environment has direct line transmitter transmitted once connection has been established; imagine old-fashioned phone-call going through switchboards. therefore transmission time same regardless of hops (well, ignoring physical time takes signal move on wire, small since it's moving @ speed of light). in packet-switched environment, there no direct connection. packet of data sent transmitter first hop, tries calculate open route destination. passes data onto next hop, again has calculate next available hop, , on. takes time linearly increases number of hops. think sendin

Is it possible to render a List<Element> in Polymer.dart? -

given list<element> elements , possible render elements in template, this? <template repeat="{{element in elements}}"> {{element.something}} </template> i'd want observe list too, add , remove elements list changes. update a ready-to-use element dart polymer 1.0 bwu-bind-html {{}} can't include html. you can use <safe-html> tag (see answer html tags within internationalized strings in polymer.dart ) <template repeat="{{element in elements}}"> <safe-html model="{{element.something}}"></safe-html> </template> but guess have change <self-html> implementation replaces content of model instead of adding model it's content, because ul / ol can't contain <self-html>

i know rising_edge(clk) , when clk'event , clk ='1'. guess detect edge. lets want read input when clk high , in mid way. guess able write want convey how can that? if not correct please explain. thanks in testbench, or synthesisable real hardware? assuming clock has period clk_period, declared like constant clk_period : time := 100 ns; -- 10 mhz clk <= not clk after clk_period/2; you can write testbench code like wait until rising_edge(clk); wait clk_period/4; value <= my_input; however not synthesisable. in real hardware need different approach. fpgas have clock generation modules (plls, dlls, dcms) allow generate phase shifted or inverted clocks, , can use such block accomplish task. more specific suggestions depend on actual fpga using, , whether have faster clocks available. for example, given clk , clk_2x phase aligned (so each clk edge clk_2x rising edge) can use falling edge of clk_2x while clk high. process(clk_2x) begin -- c
