What is maximum permissible stress?

The maximum allowable stress is that value beyond which, after applying an appropriate factor of safety its particular strength criterion is exceeded and failure occurs.

For example, if aluminum strength in yield is 35,000 psi, and factor of safety is 1.25, its maximum allowable stress against yield is 35,000/1.25 = 28,000 psi

What is the country the best technology in the world?

Firstly, what is "best" is in large part an opinion, which is up to the individual. E.g., which is the best technology: forks, or chopsticks? For the sake of being thorough, let's also take into account what technology is more "advanced." I'll say a cell phone is more "advanced" than an abacus, because the cell phone incorporates more previous technologies than the abacus.

The word "technology" applies to just about anything man-made. Therefore, the answer to your question depends on the specific technology you are thinking of.

For example, if you look at space travel, few countries could compete with the USA's space shuttle (before it was retired this year [July 2011]). However, if you compare more basic transportation systems like trains, you would find that many countries have more advanced trains than the USA.

Besides the fact that most countries specialize in different technologies than others, the impact of the internet and other communications technology should be taken into account to more fully answer your question; Today, scientists and engineers from nations all over the world collaborate to create and improve technology. It is impossible to credit a single nation for much of the technology we use today, because so much of it is shared worldwide. If you look at automobile technology, for example, you would find that American, German, Japanese, Korean, etc made autos all perform similarly; For a lot of everyday technology like cars, what is "best" or more "advanced" is mostly a matter of opinion, and can change each year or even less time.

If you're looking for which country has the most technologies that are the most advanced in the world (and that would also take into account opinions about how to calculate this...) I bet you would come up with whichever countries have the most people who are connected to the internet. I would guess this would be the USA, Japan, China, maybe the European Union if you counted it as one nation.

How do you manage your file?

Use the MY Documents Folder to store your docs. You may use different OS, but there will be some sort of Doc Folder. Create a new folder and store all your docs, spreadsheets, presentations. You can also store the files by file type as it can be easier to find them.Make separate files for docs, pdf, graphic designs etc.

When naming the file or folder, give a name that reflects its contents as it will be easy for you to make out. Also giving them useful names will also help you to distinguish between work and home files.

Hope this helps.

What is dddr4?

DDR4 is the latest installment of the hit video game Dance-Dance-Revolution. This version, however, is greatly updated. Rather than having the old standard flat, square mat to stand on, the player stands on an updated Bio/Pyro Dancing Pad recently patented by UbiSoft Inc. This Bio/Pyro Dance Pad has some new great features. For starters, rather than have the players stomping on their mats, UbiSoft has designed mats that are sensitive enough where if too much pressure is inflicted, the mat will scream "Rape!" This is designed to prevent players from damaging their new hardware without knowing it. UbiSoft realizes the embarassment one would feel from having their dance pad excplaiming it is being raped. also, the Bio/Pyro Pad has a new feature to improve player performance quickly. Rather than rating the players with scores of 'Good' or 'Perfect' or 'Miss', the Bio/Pyro Pad has a new grading system. As the player makes a mistake, the Bio/Pyro Pad begins to heat up using it's built in Thermo-Grader. As the player misses steps, the pad beings to heat up steadily per arrow at about 5 degrees per miss. This means that if a player were to miss many arrows, the pad could potentially heat up to it's maximum of 900 degrees. From this, Players will become better dancers faster and have more fun doing it. DDR4 was released in Japan in early 2009 and will be worldwide by mid 2010.

What does a vacuum tube look like?

Basically it looks (and is, somewhat) like a stretched out light bulb.

At the front you have the square flatened surface where the picture is displayed, behind it you have a stem, sort of like the stem of a light bulb.

At the end of the stem you have a filament like the one a bulb has and that send electrons towards the front.

Around that glass stem, still at the back, there are some coils which deflect the beam OS electrons to render the picture on the phosphor at the front. Those look like some noodles made of copper wire.

What is the toll free telephone number for Time Warner Cable Internet?

You can contact Time Warner Cable to order high speed internet at the toll-free telephone number 844-538-4997.

How does the internet cross the ocean?

Nearly 100 percent of international data crosses the ocean via undersea cables. They're only about three inches in diameter, but they span entire oceans. Plows dig grooves in the sandy ocean floor, lay the cables in, and the current buries them; some are buried as deep as Mount Everest is high.

This seems insane—it is insane—but we've actually been using ocean-spanning cables since 1866, when the first successful trans-Atlantic telegraph line was laid. In 1956, we started making international phone calls via deep sea cables. Today, there's a system of nearly 300 undersea cables that transport our data.

Oh, and to answer your potential followup question: Even if you're using wifi or phone data, it eventually reaches a physical cable and, if need be, sprints across the ocean.

What is the name of the person who invented mp3 players?

The German company Fraunhofer-Gesellshaft developed MP3 technology and now licenses the patent rights to the audio compression technology - United States Patent 5,579,430 for a "digital encoding process". The inventors named on the MP3 patent are Bernhard Grill, Karl-Heinz Brandenburg, Thomas Sporer, Bernd Kurten, and Ernst Eberlein. In 1987, the prestigious Fraunhofer Institut Integrierte Schaltungen research center (part of Fraunhofer Gesellschaft) began researching high quality, low bit-rate audio coding, a project named EUREKA project EU147, Digital Audio Broadcasting (DAB). Dieter Seitzer and Karlheinz Brandenburg Two names are mentioned most frequently in connection with the development of MP3. The Fraunhofer Institut was helped with their audio coding by Dieter Seitzer, a professor at the University of Erlangen. Sponsored Links Dieter Seitzer had been working on the quality transfer of music over a standard phone line. The Fraunhofer research was led by Karlheinz Brandenburg often called the "father of MP3". Karlheinz Brandenburg was a specialist in mathematics and electronics and had been researching methods of compressing music since 1977. In an interview with Intel, Karlheinz Brandenburg described how MP3 took several years to fully develop and almost failed. Brandenburg stated "In 1991, the project almost died. During modification tests, the encoding simply did not want to work properly. Two days before submission of the first version of the MP3 codec, we found the compiler error." What is MP3 MP3 stands for MPEG Audio Layer III and it is a standard for audio compression that makes any music file smaller with little or no loss of sound quality. MP3 is part of MPEG, an acronym for Motion Pictures Expert Group, a family of standards for displaying video and audio using lossy compression. Standards set by the Industry Standards Organization or ISO, beginning in 1992 with the MPEG-1 standard. MPEG-1 is a video compression standard with low bandwidth. The high bandwidth audio and video compression standard of MPEG-2 followed and was good enough to use with DVD technology. MPEG Layer III or MP3 involves only audio compression. Timeline - History of MP3 * 1987 - The Fraunhofer Institut in Germany began research code-named EUREKA project EU147, Digital Audio Broadcasting (DAB). * January 1988 - Moving Picture Experts Group or MPEG was established as a subcommittee of the International Standards Organization/International Electrotechnical Commission or ISO/IEC. * April 1989 - Fraunhofer received a German patent for MP3. * 1992 - Fraunhofer's and Dieter Seitzer�s audio coding algorithm was integrated into MPEG-1. * 1993 - MPEG-1 standard published. * 1994 - MPEG-2 developed and published a year later. * November 26, 1996 - United States patent issued for MP3. * September 1998 - Fraunhofer started to enforce their patent rights. All developers of MP3 encoders or rippers and decoders/players now have to pay a licensing fee to Fraunhofer. * February 1999 - A record company called SubPop is the first to distribute music tracks in the MP3 format. * 1999 - Portable MP3 players appear. What Can MP3 Do Fraunhofer Gesellschaft has this to say about MP3:"Without Data reduction, digital audio signals typically consist of 16 bit samples recorded at a sampling rate more than twice the actual audio bandwidth (e.g. 44.1 kHz for Compact Discs). So you end up with more than 1.400 Mbit to represent just one second of stereo music in CD quality. By using MPEG audio coding, you may shrink down the original sound data from a CD by a factor of 12, without losing sound quality." MP3 Players In the early 1990s, Frauenhofer developed the first, however, unsuccessful MP3 player. In 1997, developer Tomislav Uzelac of Advanced Multimedia Products invented the AMP MP3 Playback Engine, the first successful MP3 player. Two university students, Justin Frankel and Dmitry Boldyrev ported AMP to Windows and created Winamp. In 1998, Winamp became a free MP3 music player boosting the success of MP3. No licensing fees are required to use an MP3 player.

What is virtual com port?

A virtual port is a software emulation of a port which normally would be present in hardware. This is most commonly used with modems and printers.

Many internal modems emulate a COM port. When modems first became common by far the most common type was an external modem which plugged into a serial port (a COM port) in the back of the machine. Nearly all of the early dial-up networking applications were written with the assumption that the modem could be found on one of these COM ports. While it is no longer necessary for the modem to reside on a COM port, most new modems still emulate one in order to maintain compatibility with these legacy applications. Printers can also reside on a virtual port for much the same reasons. All printers used to plug into a parallel port (an LPT port) on the computer. As a result many legacy programs were written with the assumption that any printers would be located on an LPT port. When USB printers became commonplace it became necessary to allow these USB printers to be assigned a virtual parallel port in order to maintain compatibility with these older programs. This can be configured in the OS in the printers settings and is most often used for DOS-level point-of-sale or data-entry applications.

What are the Advantages and disadvantages of laptops?

Laptops are very handy especially if you are on the move. Some places that you may go to might have free wi fi which means that you can use the internet free of charge in particular places depending where you are that offers this service.

What organization assigns port numbers?

Port numbers are generally not assigned in the same way as an IP address or even assigned at all. Ports are always there. They can be opened, closed or accessed by programs or protocols.

So in answer to your question, organisations in general do not assign port numbers as they are not unique.
