What is the difference between a hypothesis a theory and a conclusion drawn from hypothesis testing?
A hypothesis is a suggestion of a way to explain something. If the hypothesis is tested and confirmed, it can advance to the status of theory. The conclusion of testing a hypothesis will be either that the hypothesis is confirmed, or it is not confirmed.
How would one explain the coefficient of determination?
The coefficient of determination, is when someone tries to predict the outcome of the testing of a hypothesis, or their guess at to what will happen. It helps determine how well outcomes are determined beforehand.
What is difference between testing methods testing types testing levels testing techniques?
Hi All, I think the answer for this question is, Testing method :Verification(review) and Validation Testing types : Basically static and dynamic-> in dynamic testing further can be classified into structural(white box) and functional(black box) testing Testing Technique : in white box testing we have 1) loop coverage 2)statement coverage 3) condition coverage 4) decision coverage in black box testing we have 1) Equilance partioning, 2)boundary value analysis 3) error guessing Testing Levels : Unit testing, integration testing systemtesting , Acceptance testing
What is stochastic testing?
Stochastic testing is the same as "monkey testing", but stochastic testing is a lot more technical sounding name for the same testing process. Stochastic testing is black box testing, random testing, performed by automated testing tools. Stochastic testing is a series of random tests over time. The software under test typically passes the individual tests, but our goal is to see if it can pass a large number of individual tests.
Which competing principle drives developers to keep the total number of parts small?
Developers are often driven by the principle of simplicity, which encourages keeping the total number of parts small to enhance maintainability and reduce complexity. A smaller number of components can lead to easier understanding, faster debugging, and more efficient testing processes. This principle often competes with the need for modularity, where adding more components could provide flexibility and functionality. Balancing these principles helps developers create efficient and effective systems.
Explain why eddy current testing can be carried out on all the metals whereas magnetic particle testing can only be carried out on ferromagnetic materials?
Eddy current testing can be carried out on all the metals provided the metals should be able to conduct the current. No need that it should have magnetic property. Magnetic praticle testing can be carried out only on ferromagentic materials since it works on magnetic permeabiltiy principle. Materials which has poor magnetic permeability is not able to test with MPI. This is very simple answer.
What are the non destructive tests for welding?
Magnetic Particle Testing, Ultrasonic Testing, Dye Penetrant, Radiography Testing (x-ray), Visual Inspection
What has the author Carl E Betz written?
Carl E. Betz has written: 'Principles of magnetic particle testing'
What are the disadvantages of various NDT methods?
Ultrasonic testing can be limited by material thickness and rough surfaces, while magnetic particle testing requires magnetic materials and surface preparation. Radiographic testing exposes workers to radiation, and dye penetrant testing can miss subsurface defects. Eddy current testing is sensitive to material conductivity variations and surface conditions.
What is the formula to compute the amperage of a ring in magnetic particle testing?
The formula to calculate the amperage of a ring in magnetic particle testing is Amperage = Voltage / Resistance, where Voltage is the potential difference across the ring and Resistance is the total resistance of the ring. The amperage determines the magnetic field strength generated by the ring to magnetize the test specimen for detecting any discontinuities.
What is mpi?
Magnetic Particle Inspection - An NDT (Non Destructive Testing) method primarily used to find surface breaking flaws in ferrous materials.
What is magnetic particle testing in NDT?
This ndt method is used for the detection of surface an near to surface discontinuities in ferromagnetic materials,by applying a magnetic field and a medium sensitive to areas of magnetic flux leakage.This medium will be attracted,and held,to the part surface(by the flux leakage)and the visual indication of a discontinuity then interpreted by a qualified operator.
What is the eddycurrent principle?
there is a permanent magnet and a conductor (metal)in relation. when the conductor is moved by cutting the magnetic relay. there will be a charge in the conductor. this is the eddy current priciple
What is the principle of universal testing machine?
Utm works on force and elongation/deformation principle.
How do you explain welding defects and explain its testing?
Defects can be varied and classified as critical or non critical. Porosity (bubbles) in the weld are usually acceptable to a certain degree. Slag inclusions, undercut, and cracks are usually non acceptable. Some porosity, cracks, and slag inclusions are visible and may not need further inspection to require their removal. Small defects such as these can be verified by Liquid Penetrant Testing (Dye check). Slag inclusions and cracks just below the surface can be discovered by Magnetic Particle Inspection. Deeper defects can be checked thru X-raying.
Is the definition of criteria?
A standard or principle for evaluating or testing something.
What is the main tool for autoimmune disease testing?
The principle tool, however, for authenticating autoimmune disease is antibody testing
