1.

What are main strength and Strain material parameters characterising    material performance during at Tensile loading?

-Young’s modulus

-Yield strength,

-Elongation

-Reduction in area

-Ultimate tensile strength

-Fracture strength

2.What equations describe the Strain hardening stage on true stress- true strain curve above yield strength And before reaching the necking?

-Holomon equation

-Ramberg-Osgood equation

3.What is Hall -Petch equation And what is the meaning of the main parameters in this equation?

-correlating the material Behaviour with yield strength

-Decreasing the grain size, increase the yield strength

-Increasing s_i (Stress acting against Dislocation movement), increase  the Yield strength.

4.What are main mechanical testes Applicable

QUIZ 4-EDITING

1.      1)  The principle that the meaning of a shot is determined not only by the material content of the shot, but also by its association with the preceding and succeeding shots is known as The Kuleshov effect.

2.       2) Graphic match is when two shots are juxtaposed in a way that emphasizes their visual similarities.

3.       3) The standard shot pattern that directors use to film conversations between two characters is shot/reverse shot.

4.       4 ) A scene edited in the Hollywood tradition begins with a(n) establishing shot .

5.       5) An abrupt shift in the time and space of an action that is not signaled by an appropriate shot transition is a jump cut.

6.      6)  A Master shot is a shot that

Relational Algebra and Relational Calculus

Relational Algebra and Relational Calculus are the formal query languages for a relational model. Both form the base for the SQL language which is used in most of the relational DBMSs. Relational Algebra is a procedural language. On the other hand, Relational Calculus is a declarative language. Relational Algebra and Relational Calculus can be further differentiated on many aspects, which I have discussed below with the help of a comparison chart.

a structure is called statically indetermined if there is at least one load for which the external and internal reactions can be comptuted from the psequilibrium equation but not uniquely.

PS. A satically determined structure obtained from the original one by removing. N constraints and introducing the corresponding force/moments as redundants (Xi, i=1,2,...N)

Flexibility coeff. Aij is the displacement in the line of Xi due to Xgorritoj=1

Stiffness coefficients aij unbalanced force/moment at the ith artificial constraint due to a unit displacement applied at the jth artificial constraint

Load constants ai0 unbalanced force/moment at the ith artificial constraint due to the action of the given loads a0

A transistor that uses an electric field to control the electrical behaviour of the device. FETs are also known as unipolar transistors since they involve single-carrier-type operation. Many different implementations of field effect transistors exist. Field effect transistors generally display very high input impedance at low frequencies. The conductivity between the drain and source terminals is controlled by an electric field in the device, which is generated by the voltage difference between the body and the gate of the device.

FETs can be majority-charge-carrier devices, in which the current is carried predominantly by majority carriers, or minority-charge-carrier devices, in which the current is mainly due to a flow of minority carriers.... Continue reading "Mach holding mode is carried out by" »

Phys Evidence - Serv Envirom

(Important element of service mark mix) Service environment relates to style and appearance of physical surroundings and other elements by custom designing. Service environment is an art, involves time, effort, and can be expensive.

Purpose of Service Environment: Shape customer's experience and behavior, signal quality and position, differentiate and strengthen brand, core component of value position, facilitate service encounter.

Servicescape Model

Model developed by MaryJo Bitner. An important contribution of Bitner's is the inclusion of employee responses to service environment. Internal customer and employee responses can be cognitive, emotional, or physiological responses. Dimensions of service environment include...

Frame: it refers to a single image ,it is the minimum unit in firm. The smallest compositional unit if a film´s structure, captured by the camera on a strip of motion picture film. A serie of juxtaposed and shown in rapid succession make up a motion ( or moving) picture.The rectangular area within which the film-maker composes the film image.( a film is what we see) and framing how the frame is composed. The rate in film is 24 per second and 25 frames per video and tv.FPS: present-day films are usual run through a camera or projector at a frame rate of 24fps ;older films, made at 18 fps appear jerky and speed-up when played back at 24fps. Ex: action scenes; over-craking refers to changing the frame rate, thereby producing  slow-motion action... Continue reading "What is the time of the pet" »
