What is the process of underwater welding?
Underwater welding uses a special flux around the welding rod which produces gasses which form a bubble around the end of the rod ,excluding the water. It is difficult and never as strong, lacking penetration. It is only used when absolutly necessary.
Does the Taipei 101 curve to withstand wind's force?
Yes, the Taipei 101 does curve a bit, but it also moves along with the direction of the wind due to the gigantic steel ball, called a tuned mass damper, placed near the top of the building.
i dont think there are disadvantages,
im like googling this and i cant find annyyythinng ! (n)
Does effectiveness of a heat exchanger depend on operation condition?
Yes it does. As with any device, a heat exchanger is designed to work within certain parameters. If the conditions exceed these limits, the effectiveness of the heat exchanger is compromised, and my wind up not functioning at all.
road transport are highways , bridleways or bridle paths, or carriageways, used by people, cars to move from one point to another as a means of communication
What causes people to invent things?
People decide to invent things to improve the world and quality of life. Not everyone is capable of being an inventor. Inventors alike possess skills such as analytic skills, creativity, attention to detail, curiosity and persistence.
How much do submarine cables cost?
A. The cost of a submarine cable depends on its length, how many fibres it contains and the number of channels it is intended to carry. To give you an idea, a single transatlantic cable would cost around $500m ( £307,443,000). We can carry out feasibility studies and costings for any systems you may be considering.
What are the largest Telecom vendors in the world and and in what order?
Ericsson Alcatel-Lucent Nokia-Seimens Nortel Hua Wei ZTE Motorola UT Starcom
Many would think so (with some justification), my computer cam with it pre-installed and it has not been stable and none of my old applications would work on it.
What is risk analysis and risk management in software projects?
Risk Analysis: Process of determining the probability and impact of a risk.
Risk Management: The group of processes used to identify, analyze, and respond to risks.
Risk analysis and management are a series of steps that help a software team to understand and manage uncertainty. Many problems can plague of software project. A risk is a potential problem; it might happen, it might not. But regardless of the outcome, it's a really good idea to identify it, assess its probability of occurrence, estimate its impact, and establish a contingency plan should the problem actually occur. The key to managing risks is to build contingency plans for risk and to build enough time into your project schedule to mitigate risks that you do not know about.
Project Risk Management:
Any work, that is done will always have some uncertainties that give rise to project risks, which need to be managed. A project risk is an event that, if it occurs, has a positive or negative effect on meeting the project objectives. The primary purpose of project risk management is to identify the risks and respond to them should they occur.
Project risk management includes the following:
1. Plan risk management - Decide how to determine and execute the risk management tasks.
2. Identify risks - Identify the potential risks relevant to the project at hand and determine the characteristics of those risks.
3. Perform qualitative risk analysis - Assess the probability of occurrence and the impact for each risk in order to prioritize risks for an action or for further analysis.
4. Perform quantitative risk analysis - Estimate the effects of identified risks on project objectives.
5. Plan risk responses - Develop action options for risks to maximize opportunities for and minimize threats to satisfying project objectives.
6. Monitor and control risks - Track identified risks, implement risk response plans, identify new risks, and evaluate the effectiveness of risk management processes throughout the project.
The goal of risk management is to help meet the project objectives and to help avoid/handle situations that might compromise the project schedule or outcome.
What is the difference in grades of steel such as 440 as compared to 1065?
No simple answer here, unfortunately.
Depends upon the intended application: as 440 is hi-carbon Martensitic, & commonly utilized for knife blades, etc.
1065 is a medium-carbon no-alloy (utility) type.
Pick-up a Machinery's Handbook or similar reference for more info, Mate .......
Die attach is attaching a die to some sort of packaging or equipment. This is used a lot by people who own a circuit.
Are there XM radio reception problems in northeast United States?
I am having dropouts every 5 seconds or so (this afternoon)
There are probably many contenders for the title 'Most significant'.
Because it changes the basic, underlying principles involved in what used to be called a constant velocity joint, the 'Thompson coupling' recently invented in Australia by Glen Thompson would qualify.
Previously to this invention, constant velocity joints were not truly constant velocity. The Thompson coupling is truly constant velocity and is claimed to save about 8% of the previously wasted energy.
The resistance is equally proportionate to "r" in the case that it is above 1. Assuming "r" is greater than 1, the resistance is 4/3 multiplied by omega (the equal proportionate value for mass times ohms).
If "r" is less than or equal to 1, there is no resistance.
What is cold-crushing strength of refractory materials?
cold crushing strength of a refractory brick is gross compressive stress required to cause fracture. Maximum Structural load that a material can withstand without fracture
What is water pressure tunnel?
Pressure tunnels are tunnels used to divert water from a reservoir, usually to a hydroeletric power house. They take their name due to the fact that, instead of most commons tunnels in wich the main load is geostatic (pointing inwards the tunnel), pressure tunnels are submited to high water pressures pointing outwards the tunnel.
Tool is just a method or you can say software or hardware which is helpful for doing some inventions or new things or to test something which we want to make but first we want to test that will work hopefully or not.
What are the applications of IC 74147?
This is a priority encoder. When the individual input lines are driven low, this chip outputs the index number of the highest-numbered input line that is low, in binary-encoded form, on its four output lines. If inputs 2 and 6 are both low, the output is 6 (1010). If 6 and 8 are both low, the output is 8. If 2, 6, and 8 are low, the output is 8. And so on.
What is maintained and nonmaintained emergency light?
maintained is where the light is constantly on all the time, For example,, when you go to cinema, There will be a maintained emergency light on the top of the exit door. This light will on constantly no matter the normal AC power outage or not.
Non-maintained is where the light is normally off until power loss or emergency situation. For example, In the corridor , there always a non-permanent emergency luminary & a normal luminary.
When the AC supply work well. We turn on the normal luminary to light the corridor by switch, The emergency luminary keep off.
Once the AC supply outage, the normal luminary can't work. The non-permanent emergency luminary will turn on automatically.
What is the weight bearing capacity of one inch threaded 316 stainless steel?
on a solid structure the bearing weight is according to thickness x.414 +span
