that we’d like whatever parser we build to be open-ended, allowing somebody using the parser/library to extend it in different ways (Canadian postal codes, for example) without having to modify the source itself. This is known as the “open-closed principle”: Software entities should...
Attempts to later give everybody another beer require another foreach loop, which violates the Don’t Repeat Yourself (DRY) principle. We could, of course, gather the beer-issuing code into a method (classic procedural commonality response), like so: XML Copy static void GiveBeer(List<...
where, d is the least distinct vision f is the focal length of the convex lens simple microscope diagram principle of simple microscope the working principle of a simple microscope is that when a sample is placed within the focus of the microscope, a virtual, erect and magnified image is ...
The principle of semiconductor detectors is based on the generation of electron-hole pairs in a semiconductor by the incident BSE electrons. In simpler words: BSE electrons that hit the detectors excite the silicon electrons, creating an electron-hole pair. To form an electron-hole pair in ...
as well as Z-motion thrusters and thrusters containing scanning thrusters.The above system also includes a controller that can receive deflection sensor signals and control actuators.The control section includes multiple signal processing sections, each of which can receive deflection sensor signals, provi...
All ofthecommonly used cleanroom airborne particle counters, regardlessoftheir manufacturer, work on a Light Scatteringprinciple.Essentially, this means the particle counters utilise avery brightlight source to illuminate the particles. Nowadays thissource is alaser diode, previously gas lasers and "white...
The display principles of TN-LCD, STN-LCD, and DSTN-LCD are basically the same. The difference is that the twist angle of the liquid crystal molecules is somewhat different. Let's take a typical TN-LCD as an example to introduce its structure and working principle. In a TN-LCD liquid ...

Based on numerical simulations of the intensity field distribution, we present an illumination concept for a super-resolution microscope which allows a three dimensional (3D) optical resolution around 150 nm for working distances up to the centimeter regime. In principle, the system allows great ...
