What to do if you find out that the auxiliary apparatus to be installed is not according to specification?

First you already have noticed that there is some type of problem that needs possible correction; that means you have a general knowledge of the apparatus and the specifications. I would check to assure that there aren't some amended spec's issued. Check with the original contractor/installer and give them your concerns. Notify your immediate supervisor to assure they are aware of your observations. Note: If there is a safety concern, expedite your efforts; warn operators if applicable.

How do you check that components meet the required specification and operating conditions?

There are institutes like IEEE/IEC who frames standards on which a device or component should be designed. To check whether the device is following the standard or not, these institute also mention various on-site tests that can be conducted by manufacturer or consumer.

Evert industry has its own testing lab which confirms the standard condition of its equipment. Also external labs like CPRI also helps in this.

Why Software doesn't wear out explain?

Hardware Failure Rates

The illustration below depicts failure rate as a function of time for hardware. The

relationship, often called the "bathtub curve," indicates the typical failure rate of

individual components within a large batch. It shows that in say a batch of 100

products, a relatively large number will fail early on before settling down to a steady

rate. Eventually, age and wear and tear get the better of all them and failure rates rise

again near the end of the products life. To assist in quality control, many new batches

of products are 'soak' tested for maybe 24 hours in a hostile environment

(temperature/humidity/variation etc.) to pinpoint those that are likely to fail early on

in their life, this also highlights any inherent design/production weaknesses.

These early failure rates can be attributed to two things

• Poor or unrefined initial design. Correcting this, results in much lower failure

rates for successive batches of the product.

• Manufacturing defects i.e. defects in the product brought about by poor

assembly/materials etc. during production.

Both types of failure can be corrected (either by refining the design, or by replacing

broken components out in the field), which lead to the failure rate dropping to a

steady-state level for some period of time.

As time passes, however, the failure rates rise again as hardware components suffer

from the cumulative effects of dust, vibration, abuse, temperature extremes and many

other environmental maladies. Stated simply,

"…The hardware begins to wear out."Software Engineering Topic 1 Page 10

Software Failure Rates

Software is not susceptible to the same environmental problems that cause hardware

to wear out. In theory, therefore, the failure rate curve for software should take the

form shown below.

Undiscovered defects in the first engineered version of the software will cause high

failure rates early in the life of a program. However, these are corrected (hopefully

without introducing other errors) and the curve flattens as shown. The implication is

clear. Software doesn't wear out. However, it does deteriorate with maintenance as

shown below.

During its life, software will undergo changes and it is likely that some new defects

will be introduced as a result of this, causing the failure rate curve to spike as shown

above. Before the curve can return to the original steady-state failure rate (i.e. before

the new bugs have been removed), another change is requested, causing the curve to

spike again. Slowly, the minimum failure rate level begins to rise-- the software is

deteriorating due to change.

What is the importance of sieve analysis?

The preparation or introduction of Sieve Analysis a sample of the aggregate must be obtained from the source. The aggregate, the total weight is required. it should be mixed thoroughly and then reduced to a suitable size for testing in order to prepare the sample.

What is temperature of ice in freezer?

If you mean the temperature inside a freezer, these are usually around -18 to -19 degrees celsius or 0 to -2 degrees Fahrenheit

What are the precautions should be taken while logging in to the unix operating system?

When logging into any system on a computer, you should be very careful not to leave your log in information where it can be accessed. Always make sure you close out any page with your personal information before leaving the computer.

What is the importance of DOS in Windows?

dos environment has importance because it provides a set of cammands that enable the users to interface to acess or manipulate information on their disk, as well as simly interact with their computer.

Six sided figure?

Cube

A six sided plane figure is a hexagon. A six sided solid figure is a hexahedron, and could be a cube if all six sides are squares.

Why is the design process so important to follow when creating a solution to a problem?

A design process is important to follow because it helps makes sure all stages are completed. In addition, it helps insure that the problem will be answered in an amount of time agreed upon in the design brief. Thirdly, if you are applying for a patent, it will show complete documentation from start to end in a systematic order. Lastly, it helps the engineers and other participants focus on the current stage, and produce the best product in a certain time frame.

Why are robots expensive?

Toy robots can be found under $50.

A Roomba floor cleaning robot retails for about $150.

Industrial robots can cost many thousands of dollars.

What is thrust force?

Thrust is a reaction force described quantitatively by Newton's second and third laws. When a system expels or accelerates mass in one direction the accelerated mass will cause a proportional but opposite force on that system.

How much does it cost to make a hydroelectric dam?

2 to 4 years, maybe even longer.

And it automatically starts to produce energy rather than coal fired energy which would take longer.

Why would a photographer use a pinhole camera?

probably to take a picture of something very bright, like the sun.

In reality, the pinhole camera is not the ideal instrument for taking photographs of the sun. It is used instead to create certain specific effects in the photograph. Light passing through the pinhole is not brought to a sharp focus on the image plane in the same way a lens would, so the sharpness of the image is limited, and dependent on the size of the pinhole, the distance of the pinhole from the film plane, and the amount of diffraction from the edges of the pinhole. Even with optimum sharpness, the image will be very soft, with fairly fuzzy outlines. In the hands of a skilled photographer, the effect can be very pleasing.

What is the difference between Value Management and Value Engineering?

Value analysis is "A Systematic and objective evaluation of the value of a goods or service, focusing on analysis of function relative to the cost of manufacturing or providing the items or service". value analysis provides insight into the inherent worth of final goods or service, possibly altering specifications and quality requirements that could reduce costs without impairing functional suitability. Value engineering is "Value analysis conducted at the design engineering stage of the product development process." In summary value analysis refers to the analysis of an existing product, service or administrative process while Value engineering refers to the same analysis applied to the product ,services or administrative processes that are under design and have not been finalised.

Who is the founder of networking?

Anirudha Patil is regarded as father of Load Balancers and Security

What subjects are required for automobile engineering?

Subjects required are physics, mathematics, fluid mechanics, solid mechanics, cartography, electricity, and machine tools.

How do radiators work?

In most of them, hot water heats metal tubes they in turn radiate the heat. In electric ones, a small element heats tubes filled with oil and they radiate it.

The process is known as convection.
