Iron and zinc plates are used for producing negative electrodes since these materials produce a high charge.

Transistors are successfully used for transforming heat energy into electrical energy by means of thermal elements.

By raising the cathode temperature we increase the number of emitted electrons.

In spite of its having been compressed, the gas returns to its original volume as soon as the applied forces are removed.

This splitting of the hydrogen molecule is attended by the absorption of a large amount of energy.

The circuit’s breaking causes the magnetic field to disappear.

At the continued heating of a solid body the movement of its molecules becomes still faster.

Each sampling plan states the sample size and the decision criteria for ac­cepting or rejecting a batch.

A working group in quality circles receives training in the methods of prob­lem-solving, analysis and reporting.

A new approach to the problem of “gold light”

One of the most interesting and important data of converting one form of energy into another is that of turning power into light. The first and still the most widely used method of generating light depends upon the phenomenon of incandescence. Another method of considerable practical importance is that of causing radiation by the passage of an electric current through gas or vapour. The third method of converting energy into light is called electroluminescence.

Multimedia Applications From Microsoft Multimedia Programmer’s Reference

A multimedia application is an application that incorporates sound, video, or both. It delivers information more powerfully than printed material or standard sound and video. Unlike printed material, a multimedia application contains more than a series of static images or text. Unlike standard sound or video presentations, a multimedia application allows the user to navigate through media and interact with information quickly and easily. Even when the focus of the application is to help a user produce a printed document or perform calculations, the application can use sound, video, or both to enrich the user’s experience.

Developing multimedia applications can be as simple as adding an existing sound or video recording to an application or as complex as building an editing tool for customizing multimedia presentations.

Practically any computer that uses the Microsoft® Windows® operating system and has a VGA monitor and a sound card can exploit multimedia features. Millions of computer users already own equipment like this, and many also have compact disc (CD) players. More and more, these computers are becoming the final deliverysystem for information. People are sending electronic mail instead of letters. Instead of reaching for a bulky printed encyclopedia, they are enjoying the full-color graphics, sound, and video of a CD-based encyclopedia.

The definition of a multimedia computer has been established by an industry-wide group, the Multimedia PC Marketing Council. This council has defined two sets of minimum specifications for multimedia computers. An application does not need to take full advantage of all of this hardware to qualify as a multimedia application.

An increasing number of applications are using sound and video in new and exciting ways.

For example, real estate agents have long organized descriptions and photographs of homes in large catalogs. Because these catalogs are printed on paper, the presentation of the homes is limited to a picture and some text. When the catalog is produced as a multimedia application, the agent can include a guided audio and visual tour of the inside and outside of these homes. Having potential buyers view these listings is a powerful sales tool and could prevent wasted trips to unsuitable locations.

This real estate application is just one example of what you can do with multimedia. You can use multimedia to create applications that play, edit, and capture sounds and images. You can also create applications that can control multimedia hardware, such as CD players, joysticks, video-cassette recorders, and MIDI devices.

Many developers use multimedia to improve applications that did not use sound and video when they were first designed and written. For example, developers are adding voice-annotation capabilities to word-processing applications, and video clips to presentation-graphics applications.

Some applications integrate multimedia features more completely. Software developers are creating hundreds of such applications, such as entertainment programs, computerized reference works, and educational programs. Because extensive use of sound or video requires a great deal of data-storage space, these applications are often distributed on CDs.

You can create multimedia applications for anyone who routinely needs fast access to large amounts of data. These applications are often written for niche markets; the multimedia real estate catalogue discussed earlier is a good example.

Before writing a multimedia application, you should be familiar with programming in the Windows environment When using the multimedia services, you must include the appropriate header files in all source-code files that call multimedia functions. These header files depend on declarations made in the WINDOWS.H header file, so you must first include WINDOWS.H. The multimedia headers files are: DIGITALV.H, MCIAVI.H, MMSYSTEM.H, MSACM.H, VCR.H, and VFW.H. To determine which header is needed for a multimedia element, use the QuickInfo button in the reference page for the element, or refer to the file WIN32API.CSV.

You must also link to the appropriate import library when linking an application that uses multimedia interfaces. The import libraries are MSACM32.LIB, WINMM.LIB, and VFW32.lib. Use QuickInfo or WIN32API.CSV to determine which import library to use to resolve a call to a multimedia function.

You may need to check the installed version of the multimedia system, particularly if your application takes advantage of features that were not available in previous systems. Use the GetVersionEx function to check the version.
