Mobile computing

Mobile computing with the mobile communications, Internet, databases, distributed computing technology and the rise of new technologies. Mobile computing technology will enable a computer or other intelligent terminal device information in the wireless environment, data transfer and resource sharing. Its role is useful, accurate, timely information to any time, any place, any customers. This will greatly change the way people live and work. Mobile computing is a multi-disciplinary, covering a wide range of emerging technologies, computing technology is a hot research field, and is considered far-reaching implications for the future direction of the four techniques. In 2003, Intel developed the "Centrino" is a mobile technology including the new Pentium-M processor, Intel 855 chipset and Intel PRO Wireless Network Connection module for mobile computing platforms, it will open up the development of human computing a new milestone for the people's life and work to bring freedom and unprecedented computing experience. The technology will also enable the portability of mobile terminals has been a real increase, and thus gave birth to many new features and application design patterns, while new mobile computing technology communications and computing industry in China will bring new business opportunities will promote the emergence of new value chains and development.
 Mobile computing using a variety of radio frequency (RF) technology or cellular communication technology, allowing users to carry their mobile computers, personal digital assistants (pDA), BP machines and other telecommunications equipment, free roaming. Mobile computer with a modem users should fall into this category, but they focused on the wireless remote user. Mobile computer users rely on electronic information delivery service reported, so that they can no matter where we go and the office keep in touch. Some manufacturers, Microsoft, is building a special interface to support mobile users. For example, when a mobile user from one place to another, it will resume talks in the final arrangement and the desktop to open the file, the same as the computer is never turned off.

Knowledge Grid

Concept Fran Berman earlier proposed the concept of knowledge grid, knowledge grid is an intelligent interconnection environment that enables users or virtual roles to effectively capture, publish, share and manage knowledge resources, and other services for the users and to provide the required knowledge services, support for knowledge innovation, and work together. Problem-solving and decision support, which contains characteristics of the human cognitive epistemology and ontology; application of social, ecological and economic principles; adoption of next-generation Internet technologies and standards used, knowledge grid will go beyond the existing information retrieval , filtering, mining, question answering and other technical fields. traditional natural language processing, speech and handwriting recognition, scientific computing, formal semantics, and security is not the main direction of the knowledge grid. The next generation of Internet-related research for the knowledge grid provides the technology and implementation platform of knowledge grid "grid" computing grid than the "grid" is broader, the grid is not the only implementation of the Knowledge Grid platform, but the knowledge Grid should absorb the concept of the grid. Knowledge of the characteristics of the grid Knowledge Grid has the following five characteristics different from other technologies. First, people can get through a single semantic entry and management of global distribution of knowledge, knowledge without having to know the specific location of the second, the global distribution of knowledge can be intelligently aggregate, and by reasoning with background knowledge needed to explain mechanisms services. One way to achieve this goal is to provide knowledge to provide meta-knowledge. unified resource management model will help to achieve the dynamic aggregation of knowledge services. Third, people or virtual roles can be mapped in a single semantic space, based on the reconstruction and abstract reasoning share knowledge and access to services, in which there is no obstacle to mutual understanding, knowledge grid will enable a more universal knowledge sharing. Fourth, knowledge of Grid should be able to globally search the knowledge needed to solve the problem, and to ensure proper closure of knowledge (ie, minimum set of complete knowledge). To achieve this goal, we need to create new knowledge organization model. Fifth, in the knowledge grid environment, storage of knowledge is not static; it can maintain constant dynamic evolution of the new, which means that the knowledge grid knowledge services in the course of evolution can continue to automatically improve.

Three strategies to eliminate female house nirvana waist fat

The waist is a woman of the most critical parts, which can directly affect the female body is good or bad. Waist fat is very easy to form, once formed and very difficult to remove, and daily life very difficult exercise to the waist, in the end what is a good way to place it fat on the waist? Here let us teach you a few specifically for the small waist sports bar. Move the ball movement Supine, a tennis ball in his hand, raised his hands and directed at the ceiling, legs straight and close together, feet hooked. Tighten the abdomen and buttocks muscles, shoulders and head off the ground a few centimeters. The ball is always determined not to move up toward the roof. Bicycle Exercise Just want you to lie on the floor pretending to pedal an imaginary bike. Correct action is to lower back pressed the floor, his hands placed after the first. Mentioned in the knee 45 degrees angle, your feet do the pedaling action, the left ankle to hit his right knee, right ankle and then using the touch the left knee. Knee movement Find a strong chair, the edge of a chair, knees bent, feet flat on the floor. Tighten the abdomen, the body slightly backward, lift your feet off the ground a few centimeters. Stable movement, pull your knees to the chest, while the upper body before the song. Then your feet back into place, repeat.

OGSA (Open Grid Services Architecture)

Basic informationOGSA (Open Grid Services Architecture) is called next-generation grid architecture, which is in the original "five hourglass structure" based on the combination of the latest Web Service technology initiative. OGSA, including two key technologies that grid technology and Web Service technology. With grid computing research, it is increasingly found important grid architecture. Grid architecture is about how to build grid technology, including the grid and the basic function of each part of the definition and description of the relationship between the various parts of the grid and integration method provides an effective operational mechanism characterization of the grid. Clearly, the grid architecture is the skeleton and soul of the grid, the grid is the core technology, only a reasonable grid architecture to be able to design and build a good grid to be able to function effectively mesh. OGSA most prominent idea is to "service" as the center. In the OGSA framework, everything will be abstracted as services, including computer programs, data, equipment, etc. This concept is conducive to a unified standard interface through the management and use of the grid. Web Service provides a service-based framework, however, Web Service are generally faced with a permanent service, and in the grid environment, a large number of the temporary short-term services, such as a computing task execution. Taking into account the specific characteristics of grid environment, OGSA services in the original Web Service based on the concept, proposed the "Grid Service (Grid Service)" concept for solving service discovery, dynamic service creation, service lifecycle management and temporary service related issues. Based on the concept of grid services, OGSA entire grid as a "grid service" collection, but this collection is not static, can be extended, which reflects the dynamic nature of the grid. Grid services by defining the interface to perform different functions, the service is data about the grid service instance information, the grid service can be simply expressed as a "grid service = interface / behavior + service data." At present, the grid services interface is still relatively limited, OGSA is continually improving the process, the next step will consider expanding the management, security, etc. aspects.Edit this paragraph to the grid service-centric model has the following advantages1. As the grid environment, all components are virtualized virtualized, therefore, provides a relatively uniform through the core interfaces, all of these grid services are based interface, you can easily construct a hierarchical structure, higher levels of service, these services across different levels of abstraction, in a unified way to look at; 2. Virtualization also enables mapping of multiple logical resource instances to the same physical resources as possible, combinations of services without regard to the specific implementation, can form the basis of the underlying resources in virtual organizations (Virtual Organization) in resource management. Grid services through virtualization can be a common service semantics and behavior, and seamlessly mapped to the local platform infrastructure.

E-wallet

E-shopping e-wallet is a commonly used payment instrument, as its suitable for small purchases. In the electronic wallet storing the electronic money, such as electronic cash, electronic coins, electronic credit cards. Electronic purse shopping. Usually in the service system for electronic wallet. E-commerce activities in the electronic wallet software is usually free of charge. The world has two major online VISA Cash and Mondex electronic wallet system.

Four kinds of weight training a fit body dance

Exercise to lose weight has been a constant thunder of weight loss secret, but the dance movement is not only beautiful and very boring one. Want a quick and healthy body weight, and small series on a look at what the most effective dance bar.JazzJazz dance is a Broadway musical and film often appear in a dance, it has the advantage of entertaining, and easy to understand. Common combination of street jazz and hip-hop jazz flexibility of fortitude, a lot of people started learning the dance of choice.Training site: jazz dance is aerobic exercise, is a whole body movement, the main exercise abdominal, upper body, legs and leg muscle. Because it can exercise the muscles flexibility flexibility, improve the body lines very effective. Jazz dance training in the process, with time, the percentage of fat for energy increases, so would like to achieve a better body effect, exercise should be an appropriate extension of time and perseverance.Basic movements: modern dance, many steps are involved, range of motion is usually large and exaggerated, there are a lot of kicks, spins and jumps jazz.SalsaSalsa word from Spanish, originally meaning sauce. It is the Latin Dance and its music collectively, sexy passion, is today the most popular dance in Europe and America one species. Cuban style Salsa focus on rotation, Colombia-style Salsa is more focused on the pace of the complex.Exercise areas: hips, waist, buttocks and inner thighs are the most important for the body parts of Salsa, but also other sports more difficult exercise to the site. Continuous series of twisting action allows you to sweat a short time, and immediately compact the waist with a wonderful feeling.Basic movements: fast movement, there are a lot of spin and systemic action, with a heel step small step and so on. Mambo dance includes the basic steps, the two hand in hand with each other shuttle and so on.BalletFrom the 17th century as an independent dance form developed so far, the Western theater dance ballet is dominant in one kind of dance form. Ballet has a stringent set of action specifications, the dancer's movements both mechanical efficiency but also full of artistic charm.Exercise areas: mainly the abdomen and legs, but if the action in place, the body can be good exercise. Ballet training is generally divided into four sections: warm-up, basic skills (supporting the training section), ground (exercise legs, waist and other parts of the flexibility), and finally the body rhythm and dance combinations. Now the popular ballet, there are a lot of body shoulder and arm movements, especially for women, relax tense shoulders and back office.Basic actions: a series of fancy postures and leg movements, including the squat, jump deformation, large by the standards of co-operation such as ballet.Tap dance19th century was born in the United States, the name comes from the tap dance tap dance shoes strike the ground the sound. That the sound of rhythmic tap performers is not only a dancer, but also a percussion family.Training site: basically for public tap tap reduces the difficulty of performing the nature and requirements of an appropriate increase of the knee and ankle joints of activity, this exercise can tap coordination, thinking skills can be trained. Tap dance is one of the steps required flexibility, very popular, as long as you can follow the rhythm of stepping on "points" on it, it can effectively reduce leg fat, especially fat calf.Basic movements: all parts of their feet rubbing on the floor slap, tap issue of sound.
