What is the general mix of oxygen and acetylene in welding?
A general rule is 3 parts Oxygen to 1 part Acetylene. Other fuel gasses may vary the ratio. This produces a Neutral flame. See the answer to "Types of flames" for more info.
What is use of industrial psychology for engineers?
Making money for cliché-spouting management-consultants?
'
Obviously if you are recruiting staff or have supervisory responsibilities, you need to be able to deal with people sensitively and treat them with respect; but otherwise it's their abilities and willingness to carry out the work that matter. Obviously too, how you treat your staff and their union will affect their performance. You hardly need to be a psychologist to know and do that - even less so, a cod-psychologist, because your shop-floor staff will see through that pretension straight away. They might not have your fancy qualifications, but they are not naïve.

From experience, the lower their rank, the less impressed they are by managerial flannel and fads; and the older they are the more flannel and fads they have seen come and go. While they might not have the nerve to say anything, they will regard you as bonkers at best and wasting company money at worst. They look up to managers who respect them, understand the work itself and demonstrate genuine ability to win contracts and reward good staff with decent pay & conditions; not ones who dissipate their energy and company cash in glossy brochures and daft initiatives.

Unfortunately, modern business management all too easily forgets its real role and follows fads with the zeal of fashion-conscious teenagers; whether those fads are alleged "quality" initiatives, custom-made "corporate typefaces" for the company computers, or trying to fit staff-members to high-falutin' theories!

How do you use the Samuel Morse telegraph?
The telegraph uses a "telegraph key" to send the Morse code. The code is a series of dots and dashes that is used in specific combinations to represent letters of the alphabet. When the telegraph key is closed, a transmitter that it is connected to it sends out a CW (continuous wave) of the frequency that the transmitter is tuned to. The letters are formed by the length of time that the transmitter key is held down. For example the letter A ( . _ ) , it is a dot and a dash, the key is held down for a short specific time for the dot and the dash is formed by holding the key down for twice as long as the dot. An average telegrapher can read 15 words a minute, this is 15 words x 5 letters per word = 75 letters a minute. Good telegraphers can double this speed up to 30 words a minute.
What are manufacturing technology?
Manufacturing is the use of tools and labor to make things for use or sale. The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale. These finished goods are sold directly to end users, or used for manufacturing other, larger products. Manufacturing takes place under all types of economic systems. In a free market economy, manufacturing is usually directed toward the mass production of products for sale to consumers at a profit. In a collectivist economy, manufacturing is more frequently directed by the state to supply a centrally planned economy. In free market economies, manufacturing occurs under some degree of government regulation. Modern manufacturing includes all intermediate processes required for the production and integration of a product's components. Some industries, such as semiconductor and steel manufacturers use the term fabrication instead. The manufacturing sector is closely connected with engineering and industrial design. Examples of major manufacturers in the United States include General Motors Corporation, Ford Motor Company, Chrysler, Boeing, Gates Rubber Company and Pfizer. Examples in Europe include Airbus, Daimler, BMW, Fiat, and Michelin Tyre.
How has oil bring social change to Texas?
Oil has brought social change to Texas in many ways. To name a few, it has created more minority work opportunities, made the University of Texas and A&M better schools, and helped football fever. If you want more info., just research those.
Why direct current is not used for transission of electricity through wires?
Two reasons:
1. Alternating current does not loose as much power over long distance.
2. Alternating current can be stepped up or down through transformers, allowing AC to be transmitted at high voltage (even less current loss) and then it can be stepped back down inside your home.
For short distances and if there is no need to step up or down, DC is fine.
What is the history of the word engineer?
The word engineer is derived from the Latin root ingenium, meaning "cleverness
What does a coefficient of variation tell you?
It tells you about the size of variation relative to the size of the observation, and it has the advantage that the coefficient of variation is independent of the units of observation. Here is a example to help you see it.
If you have a data set with weights, the value of the standard deviation of a set of weights will be different depending on whether they are measured in grams or lbs or micrograms etc. For example if you look at the weights of kids from birth to 18 years, some countries measure in lbs other in kg and some even use stones. The coefficient of variation, however, will be the same in both cases as it does not depend on the unit of measurement. So you can obtain information about the children's weight variation around the world by using the coefficient of variation to look at all the ratios of standard deviations to mean in each country.
To compute it we look the ratio of the standard deviation to the mean .
How do you mend defects on PolyOxyMethylene?
To mend defects on PolyOxyMethylene (POM), also known as acetal, you can use adhesive bonding with specialized epoxy or cyanoacrylate adhesives designed for plastics. Surface preparation is crucial; clean the area thoroughly and, if possible, roughen it to enhance adhesion. For larger defects, consider using a plastic welding technique or applying a thermoplastic filler that matches the material properties of POM. Always follow the manufacturer's guidelines for the adhesive or filler used to ensure optimal results.

What is linear probing and quadratic probing in hashing?
Quadratic probing is an open addressing scheme in computer programming for resolving collisions in hash tables-when an incoming data's hash value indicates it should be stored in an already-occupied slot or bucket. Quadratic probing operates by taking the original hash index and adding successive values of an arbitrary quadratic polynomial until an open slot is found.
For a given hash value, the indices generated by linear probing are as follows:
This method results in primary clustering, and as the cluster grows larger, the search for those items hashing within the cluster becomes less efficient.
An example sequence using quadratic probing is:
Quadratic probing can be a more efficient algorithm in a closed hash table, since it better avoids the clustering problem that can occur with linear probing, although it is not immune. It also provides good memory caching because it preserves some locality of reference; however, linear probing has greater locality and, thus, better cache performance.

Can you give me Technology Words that start with the letter Q?
Sure! Here are some technology-related words that start with the letter Q: "Quantum computing," which refers to advanced computing using quantum mechanics; "Query," a request for data or information from a database; and "QoS" (Quality of Service), which is a measure of the performance level of a service in networking. Additionally, "Queue" is a term used in computing to manage tasks or processes.
What is difference between coaxial cable and twisted pair cable?
The answer is in the name of the cables; co-axial cable has an outer an inner part which share a common axis (hence the name co-axial). Usually the outer part acts as a screen to protect the inner part from electrical interference. Twisted pair cable consists of a number of pairs of cables. Each pair is twisted together and is used for a single signal; one side of the pair sends the normal signal, the other sends the inverted version. At the receiving end, the normal and inverted signals are subtracted, because any electrical noise is likely to affect each of the pair of cables equally (because they are coupled together by being twisted), subtracting the two should produce a noise free resulting signal. There are variations; sometimes each pair is screened - improving the noise immunity, particularly from other signals in the same cable - sometimes the entire bundle of cables is screened. Occassionally, both the individual pairs are screened and the bundle is also screened.
