LINQ to SQL or commonly called L2S was developed by the C# team of developers at the Microsoft, while EF was developed by the team that developed EF. The coupling in case of LINQ to SQL is very strong between the database schema and query classes, whereas in case of LINQ to EF, the coupling between underlying database and the querying classes is loose because you query database using Entity Data Model which introduces another layer abstraction between the database and querying classes. The major difference between LINQ to SQL & LINQ to EF is in the coupling between the database scheme and the classes that are used to query that database via LINQ. If you are not much familiar with foundations of LINQ, I would advise you to first have a look at my other tutorials on Getting Started with LINQ and Interpreted LINQ queries.īasically both LINQ to Entity Framework and LINQ to SQL are object-relational mappers on which LINQ queries can be executed. We will first start with our article by explaining how LINQ to SQL and then we will move towards LINQ to Entity framework. This article is not focused towards explaining ins and outs of entity framework this article explains that how LINQ can integrate with entity framework to achieve the desired data access feature. However, there are still plenty of features where ADO.NET beats entity framework, but developers are now switching to Entity Framework owing to its strong decoupling and separation of concerns between the business and data access logic. Entity framework is Microsoft’s latest data access technology and is considered a replacement for ADO.NET.

"Flipside" by Peedi Crakk ft Freeway ( thanks to Trife, LA) add more info Rad's warehouse? ( from trey in galesburg) What is the song playing when David and El's crew battle against Wade's crew at Mr. "I Know I Can" by NAS ( thanks to KID FREEZY, killeen,texas,united states) add more info Houston were just having shots at the basket court? ( from Eddie in Turkey) What's the song playing when Omarion and M. from rv in quezon city, Philippines ( answer rv's question) What's the song playing when L and David get lost from the other crew? "Summer Madness" Kool & the Gang ( thanks to shaniceo, england) add more info What's the title of that background song when "little Saint" died in the hospital? It's like an instrumental hitting a high note. ( from Alfrancis in Iloilo City, Philippines) ( thanks to Coolstyle, Atlanta,Georgia) add more info That song is by a group called "The Commodores." ( thanks to Gwen, South Carolina) add more infoĪctually, the real song title is "Summer Madness" by Kool & The Gang ( thanks to SinBad, DYT, Ohio, USA) add more infoĪctually, it is the jazz version of Kool and the Gang's "Summer Madness" by Grover Washington Jr. What is that jazz song that gets to a really high note? My dad likes that song, and I want to burn a CD for him for his birthday with that song on it. ( thanks to Paradox90, Peterborogh) add more info Listen to it, it's like the hip-hop version of "Fur Elise" lol! It's all good. ( thanks to Bboy Nil-Dread, Canada) add more info so it isn't the original version of the song. Yo, that song has Beethoven in it but like. Geez guys read the question properly!!! ( thanks to michael, South Africa.) add more info Those other people that answered are thinking about hiphop music only!! LOL at all those weird answers. The track is called "Fur Elise" from Beethoven. You may be thinking about the song "Heaven" by NAS/Jully Black. ( thanks to applegate, Taiwan ) add more info What's that song heard when David is playing basketball alone and he is announced about the big contest from MTV? It plays for about 20 seconds. ( from Mszili88 in Romania) Music from the movie not on this soundtrack CDĪdd more missing songs to this list, or tell us in what scenes these songs are heard or where they can be found. SoundtrackINFO: You Got Served SoundtrackĬlick You Got Served soundtrack CD for more info from The MovieMusic Store. For instance, a resistor has an influence on the real part of impedance, and a capacitor affects its imaginary part. It is reasonable that an element in a circuit contributes to the impedance change to a certain degree. Snapshot of the equivalent circuit fitting program. 2 shows an example for a non-linear curve fitting process.įigure 4. By minimizing S, the fitted element parameters can be modified so that the result impedance ( Z i,cal) can be as close as possible to the experimental value ( Z i,exp). R for a resistor, C and f for a capacitor), then S can be calculated using its defined equation. The subscript exp indicates experimental value and the subscript cal indicates the calculated value while fitting.įor any kind of circuit, Z i,cal can be calculated by the set of element parameters and the frequency (e.g. Where S is the weighted sum of squares of error, N f is the number of frequencies within an experiment, Z i is the impedance of the i–th frequency, and w i, Re and w i, Im are the statistical weights for the real and imaginary parts of the impedance of the i–th frequency. This is a general and popular method for solving the minimum value of function E(x), where The algorithm for finding all the element parameters in a given circuit is by implementing the Levenberg-Marquardt non-linear fitting method. (a) The Nyquist plot for visualizing impedance values, and (b) an equivalent circuit with several circuit elements for modeling electrode surface reactions.Įlectrochemical Impedance Circuit Fitting Program Control, analysis, fitting – everything is in one place, saving you time and facilitating electrochemical measurements.Figure 1. Advanced analysis techniques can be managed directly in the software (no need to export) with Z-Fit EIS fitting software also embedded in the interface. The SP-150e’s versatile, comprehensive specification is complemented by BioLogic’s benchmark control and analysis software EC-Lab. The SP –150e is the only ampere workstation to boast high-current capability (800 A with boosters), three EIS quality indicators (THD, NSD, NSR) for EIS validation, and Ethernet compatibility for improved group-working. Should you need more power, this versatile electrochemical workstation will grow with your research needs. This two-channel, EIS-capable electrochemical workstation is perfect for a wide range of general electrochemistry applications, but the ☑ A current range makes it especially suitable for energy applications including battery, supercapacitor, fuel cell ( RRDE compatible), and electrolysis research. The new BioLogic SP-150e is an electrochemical workstation designed to grow with your research needs. |
