  • Can I write this JQuery statement cleaner?

    - by Polaris878
    Hello, So I have the following: var box = $(".MyCheckBox"); if (box[0].checked) { // Do something } else { // Do something else } Is there a better way of doing this using filters or something? I know I can go: $(".MyCheckBox") .filter(function(index) { return this.checked; }) .each(function() { // do something }); But I need to do something in the else statement... easier way of doing this? Thanks!

  • No more memory available in Mathematica, Fit the parameters of system of differential equation

    - by user1058051
    I encountered a memory problem in Mathematica, when I tried to process my experimental data. It's a system of two differential equations and I need to find most suitable parameters. Unfortunately I am not a Pro in Mathematica, so the program used a lot of memory, when the parameter epsilon is more than 0.4. When it less than 0.4, the program work properly. The command 'historylength = 0' and attempts to reduce the Accuracy Goal and WorkingPrecision didn`t help. I can't use ' clear Cache ', because there isnt a circle. I'm trying to understand what mistakes I made, and how I may limit the memory usage. I have already bought extra-RAM, now its 4GB, and now I haven't free memory-slots in motherboard Remove["Global`*"]; T=13200; L = 0.085; e = 0.41; v = 0.000557197; q = 0.1618; C0 = 0.0256; R = 0.00075; data = {{L,600,0.141124587},{L,1200,0.254134509},{L,1800,0.342888644}, {L,2400,0.424476295},{L,3600,0.562844542},{L,4800,0.657111356}, {L,6000,0.75137817},{L,7200,0.815876516},{L,8430,0.879823594}, {L,9000,0.900771775},{L,13200,1}}; model[(De_)?NumberQ, (Kf_)?NumberQ, (Y_)?NumberQ] := model[De, Kf, Y] = yeld /.Last[Last[ NDSolve[{ v (Ci^(1,0))[z,t]+(Ci^(0,1))[z,t]== -((3 (1-e) Kf (Ci[z,t]-C0))/ (R e (1-(R Kf (1-R/r[z,t]))/De))), (r^(0,1))[z,t]== (R^2 Kf (Ci[z,t]-C0))/ (q r[z,t]^2 (1-(R Kf (1-R/r[z,t]))/De)), (yeld^(0,1))[z,t]== Y*(v e Ci[z,t])/(L q (1-e)), r[z,0]==R, Ci[z,0]==0, Ci[0,t]==0, yeld[z,0]==0}, {r[z,t],Ci[z,t],yeld},{z,0,L},{t,0,T}]]] fit = FindFit[data, {model[De, Kf, Y][z, t], {Y > 0.97, Y < 1.03, Kf > 10^-6, Kf < 10^-4, De > 10^-13, De < 10^-9}}, {{De,7*10^-13}, {Kf, 10^-5}, {Y, 1}}, {z, t}, Method -> NMinimize] data = {{600,0.141124587},{1200,0.254134509},{1800,0.342888644}, {2400,0.424476295},{3600,0.562844542},{4800,0.657111356}, {6000,0.75137817},{7200,0.815876516},{8430,0.879823594}, {9000,0.900771775},{13200,1}}; YYY = model[ De /. fit[[1]], Kf /. fit[[2]], Y /. fit[[3]]]; Show[Plot[Evaluate[YYY[L,t]],{t,0,T},PlotRange->All], ListPlot[data,PlotStyle->Directive[PointSize[Medium],Red]]] the link on the .nb file http://www.4shared.com/folder/249TSjlz/_online.html

  • Is it ok to reference .Net assemblies liberally?

    - by panamack
    I'm building a WPF application and working with the MVVM pattern. I have 4 projects in my solution, 3 class libraries, Data, Model and ViewModel and the WPF executable View. Is there anything wrong with the Model referencing WindowsBase so that I can use ObservableCollection<T> for example or can I just make use of what I intuitively feel I need without worrying about the original purposes of the class in the framework e.g. collection databinding.

  • Can an ActiveRecord before_save filter halt the save without halting the transaction?

    - by Michael Boutros
    Is there any way for a before_save filter to halt the entire save without halting the transaction? What I'm trying to do is have a "sample" version of my model that the user can interact with and save but the changes themselves are never actually saved. The following will halt the transaction and (naturally) return false when I call @model.update_attributes: before_filter :ignore_changes_if_sample def ignore_changes_if_sample if self.sample? return false end end Thanks!

  • Anyone knows from where to get that jQuery tags editor?

    - by Axel
    Hi, Someday i've downloaded a very nice jquery editor but i lost it and i only have a screenshot of it.

Please don't suggest me That because it's so poor and the tags are inserted outside the input box. Thanks

  • Microsoft Small Business Licensing Kick Start

    - by regex
    I seem to recall hearing at some point (I believe it was MIX09) that Microsoft has a licensing model of some sort where a business can consume licenses for up to two years, free of charge, until they reach a point where they are stable position and can pay their licensing at the end of two years. However, I can't find information regarding it online. I want to say that possibly stackoverflow used this licensing model to kick start their site. Is anyone familiar with this?

  • Rewriting git history to convert master branch to development branch?

    - by gct
    I'm looking to rewrite my git repo to use a new branching model I came across: http://nvie.com/git-model But right now all my history lives in the master branch. I'd like to rewrite it (possible using git-filter-branch?) So that all that history is in a branch called development now. Is this possible? It's definitely beyond my limited git skills.
