This was not a search for a `` magic formula '', but rather an examination of basic principles pertaining especially to all types of communication in marriage.

Actually, the types of infection that could attack a warm-blooded mammal were not infinite, and over the course of the last few hundred years adequate defenses had been found for all basic categories.

There are four basic types ( and several variants ) which each have a set of parameters describing the connection.

Pilots can get authorisations for differing types of displays ( i. e. limbo flying, basic aerobatics to unlimited aerobatics ) and to differing minimum base heights above the ground.

The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by nineteenth and early twentieth century engineers.

Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information-integrating capabilities of a centralized brain.

There are two basic types of ball point pens: disposable and refillable ; disposable pens are chiefly made of plastic throughout and discarded when the ink is consumed ; refillable pens are metal and some plastic and tend to be much higher in price.

The bain-marie comes in a wide variety of shapes, sizes, and types, but traditionally is a wide, cylindrical, usually metal container made of three or four basic parts: a handle, an outer ( or lower ) container that holds the working liquid, an inner ( or upper ), smaller container that fits inside the outer one and which holds the material to be heated or cooked, and sometimes a base underneath.

The three basic types of community organizing are grassroots organizing, coalition building, and " institution-based community organizing ," ( also called " broad-based community organizing ," an example of which is faith-based community organizing, or Congregation-based Community Organizing ).

Representation of four basic chemical reactions types: synthesis, decomposition, single replacement and double replacement.

Most file types also allocate a few bytes for metadata, which allows a file to carry some basic information about itself.

At the most basic level there are only two types of file operations ; read and write.

The classification identifies five basic types:

There are two basic types of dislocations, the edge dislocation and the screw dislocation.

Both the basic and most common list types in computing, queues and stacks can be considered specializations of deques, and can be implemented using deques.

Euphoria has two basic data types:

Each of the basic forces of nature is associated with a different type of potential energy, and all types of potential energy ( like all other types of energy ) appears as system mass, whenever present.

Most analog electronic appliances, such as radio receivers, are constructed from combinations of a few types of basic circuits.

* A uniform type system handling both value and reference semantics in which all types, including basic types such as INTEGER, are class-based.

There are two basic circuits that both use the term mixer, but they are very different types of circuits: additive mixers and multiplying mixers.

Four types were distinguished: born criminals ( inborn delinquents ), pathological liars, querulous persons, and Triebmenschen ( persons driven by a basic compulsion, including vagabonds, spendthrifts, and dipsomaniacs ).

* They provide a built-in viewer for ( at least ) the most basic file types.

Many building codes specify basic foundation design parameters for simple conditions, frequently varying by jurisdiction, but such design techniques are normally limited to certain types of construction and certain types of sites, and are frequently very conservative.

Therefore, four loose families of more-efficient light transport modelling techniques have emerged: rasterization, including scanline rendering, geometrically projects objects in the scene to an image plane, without advanced optical effects ; ray casting considers the scene as observed from a specific point-of-view, calculating the observed image based only on geometry and very basic optical laws of reflection intensity, and perhaps using Monte Carlo techniques to reduce artifacts ; and ray tracing is similar to ray casting, but employs more advanced optical simulation, and usually uses Monte Carlo techniques to obtain more realistic results at a speed that is often orders of magnitude slower.

* Transmission electron microscope ( TEM ): passes electrons through the sample, analogous to basic optical microscopy.

This leads to the techniques of Gaussian optics and paraxial ray tracing, which are used to find basic properties of optical systems, such as approximate image and object positions and magnifications.

An operational, non-fictional cloaking device might be an extension of the basic technologies used by stealth aircraft, such as radar-absorbing dark paint, optical camouflage, cooling the outer surface to minimize electromagnetic emissions ( usually infrared ), or other techniques to minimize other EM emissions, and to minimize particle emissions from the object.

There is no strong distinction, however, between optical physics, applied optics, and optical engineering, since the devices of optical engineering and the applications of applied optics are necessary for basic research in optical physics, and that research leads to the development of new devices and applications.

Similar to the Penrose stairs optical illusion ( as in M. C. Escher's lithograph Ascending and Descending ) or a barber's pole, the basic concept is shown in figure 1.

This binary reproduction relies on a basic optical illusion — that these tiny halftone dots are blended into smooth tones by the human eye.

There are two basic configurations of the conventional optical microscope: the simple ( single lens ) and the compound ( many lenses ).

All modern optical microscopes designed for viewing samples by transmitted light share the same basic components of the light path, listed here in the order the light travels through them:

There are many variants of the basic compound optical microscope design for specialized purposes.

SPDM ( spectral precision distance microscopy ), the basic localization microscopy technology is a light optical process of fluorescence microscopy which allows position, distance and angle measurements on " optically isolated " particles ( e. g. molecules ) well below the theoretical limit of resolution for light microscopy.

At its most basic, photometry is conducted by gathering radiation in a telescope, perhaps passing it through specialized optical filters, and then capturing and recording the light energy with a photosensitive instrument.

* Nick Holonyak Jr. Award, recognizes contributions to optics based on semiconductor-based devices and optical materials, including basic science and technological applications.

Layout of optical components in a basic TEM

The basic optical schlieren system uses light from a single collimated source shining on, or from behind, a target object.

A curved primary mirror is the reflector telescope's basic optical element that creates an image at the focal plane.

It is first useful to give a brief overview of the basic theory of optical

A generic optical tweezer diagram with only the most basic components.

The most basic optical tweezer setup will likely include the following components: a laser ( usually Nd: YAG ), a beam expander, some optics used to steer the beam location in the sample plane, a microscope objective and condenser to create the trap in the sample plane, a position detector ( e. g. quadrant photodiode ) to measure beam displacements and a microscope illumination source coupled to a CCD camera.
