asp.net mvc 4 - npgsql schema "dbo" does not exist -

-

i have problem similar entity framework 5.0 postgresql (npgsql) default connection factory

i have npgsql declared in app.config :

<connectionstrings>     <add name="mondbcontexte"           connectionstring="server=127.0.0.1;port=5432;database=ma_datab_db;user id=postgres;password=root;"       providername="npgsql" />   </connectionstrings>   <!-- le factory provider -->   <system.data>     <dbproviderfactories>       <add name="npgsql data provider"             invariant="npgsql"             support="ff"             description=".net framework data provider postgresql server"             type="npgsql.npgsqlfactory, npgsql" />     </dbproviderfactories>   </system.data> </configuration>

my context provider class: 

public class contextdb: dbcontext {     public dbset<personne> personnes { get; set; }      public contextdb()         : base("mondbcontexte")     {     } }

my "personne" class:

[table("personnes", schema = "public")] public class personne { [key] [column("id_personne")] [display(name="identifiant")] public int id { get; set; }

    [column("nom")]     [display(name = "nom")]     [required(errormessage = "merci de saisir le nom.")]     public string nom { get; set; }      [column("prenom")]     [display(name = "prénom")]     [required(errormessage = "merci de saisir le prénom.")]     public string prenom { get; set; } ... ... }

and in controller action this: 

            using (var context = new contextdb())             {                 // *** here have exception...                 var personnes = p in context.personnes                               p.nom.startswith("m")                               orderby p.nom                               select new { p.nom, p.prenom };                  foreach (var une_personne in personnes)                 {                     console.writeline(une_personne.nom + " " + une_personne.prenom);                 }

after have exception :

it seems ef uses dbo default schema database. need change "public" default schema postgresql.

you use importing namespace: 

using system.componentmodel.dataannotations;

and annotate classes use different schema:

[table("mytable", schema = "public")] class test {...}

for more information, check out post ef , npgsql: http://fxjr.blogspot.com/2013/06/npgsql-code-first-entity-framework-431.html

i hope helps.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
