Ultrafast science
Ultrafast science and technology is today's science and engineering of the most exciting areas, including from nuclear physics to astronomy of the various principles, but also includes the dissemination of medical and even surgical applications. For example, high-speed electronics (high-speed electronics, 0.5 THz), terabyte (TB) optical communication, MEMS (micro-machining), precision X-ray photography and strong sub-therapeutic (hadron therapy) and so on.
Ultrafast science behind the main purpose is to develop technology to create and control the value of ultra-short and ultra-high-power beam pulse Britain (Peak power light pulses), and use it to study atomic, nuclear, plasma and materials physics, electronics, and high energy density physics in the ultra-fast phenomena. Some of the new discovery and innovation has been to stimulate the emerging field of nano-scale science development.

UMA Upper Memory Area
DOS system between 640KB to 1024KB of memory, generally can not access the DOS program, also known as HIGH MEMORY.

UML Unified Modeling Language
A by OPEN MANAGEMENT GROUP (OMG) funded the development of a common standard markup language specification, used for a unified Gejia computer-aided software design (CASE) tool vendors support different factions of the way the theory expressions.

UMS
UMS to say there are many, such as: Unified Mail, Unified Messaging, Universal Messaging, Integrated Mail, Integrated Messaging and so on, were briefly as follows:
Unified Mail (unified messaging):E-mail can be stored in a variety of different media, such as: Voice (voice), fax (fax), e-mail (email), video (video), and call messaging (paging) and so on, may, by telephone or computer (PC or telephone ) to read the messages.
Unified Messaging (Unified Messaging):In addition to storing a variety of different media messages, but also can use the telephone or computer to send mail and reply to e-mail. Can even contact the real-time and left a message.
Universal Messaging (general information):This is the final goal, the use of any communications equipment issued by mail and reply to messages, do not have to consider each other's communications equipment is able to read these forms of media messages.
Integrated Mail (integrated e-mail):One way to achieve Unified Mail In fact, a variety of different media messages were stored, but with access through a single interface.
Integrated Messaging (integrated information): One way to achieve Unified Messaging, in fact a variety of different media messages were stored, but with access through a single interface.
UMS service should have the following features:
24 hours to accept other people's voice mail and fax telephone numbers doors.
I have the phone number the user door, UMS number and password at any time to receive e-mail, voice mail and fax, and can use voice and fax reply to e-mail and send the message.
The user himself or through any e-mail software dedicated web pages, ready to deal with e-mail, voice mail and fax.
Through a pager (pager), cellular phone short message (SMS), was immediately informed of the availability of voice, fax and e-mail.
