Comparison of SCA with OSGI

SCA has recently looked at norms and OSGI specifications. After reading again to make a comprehensive comparison between the two.

First, the two normative starting point and the mind is not the same. SCA specification is for enterprise application integration and development, OSGI specification is the original purpose of computing for mobile devices drawn. Since the two different starting point, leading to the focus of two different specifications. SCA specifications version now is 0.95, relative OSGI specification 4.0 version also appears to be somewhat immature.

SCA specification focuses on solving the existing call between enterprise applications and enterprise applications to service-oriented thinking on how to build and deploy. However, the realization of the component requirements in respect of the container is some lack of standing on the user's perspective simply describes the specifications of the client API.

The OSGI specification as the initial starting point is the computing environment for mobile devices, so more consideration to the run-time framework and services in the run time of the dynamic matching problem. In addition, the application provides a run time of hot deployment, analysis, operation, unloading capacity. It should be said, OSGI specification 4.0 has been developed to a relatively well regulated.

SCA SCA specifications now on the realization of the container, not one of guiding ideas, but OSGI standard in this area have done very refined. OSGI specification defines a Framework, Start Level, Package Admin, Security, a detailed description of the dependence between different components of the rules (static dependency, dynamic import), between the different components of the class name using a separate space.

As the SCA specifications for enterprise application integration, the implementation of SCA components can be Java, BPEL, EJB, WebService. The implementation of OSGI only for Java language. This is also the starting point because the two different result.

The SCA and OSGI the assembly model, the two are similar. Both are outside services (Service), but the SCA is more emphasis on design time component assembly, and the definition of a flexible component assembly model, the smallest atomic components can be assembled into a large system.

Has been achieved from the existing products of view, OSGI more be used as a single product of the overall structure, SCA specifications are more business-oriented components used in the assembly specification, as the structure of how the SCA products SCA specification is not a concern.

From the comparison on top can see the obvious shortcomings of the two separately, SCA specifications too much emphasis on integration, but the running time of the SCA component behavior description is too weak, all the components are designed to achieve time bound. Perhaps the product can be achieved in the SCA runtime dynamic binding, but as a norm, this is what it lacks. OSGI standard description of the components of the running time is complete, but all components must run in the same virtual machine, virtual machine service component interoperability is slightly insufficient.

The future, including 120-inch flat panel, Changhong may also pioneered. Guo high hopes for this group of products, said the move will mean "for our marketing team to provide new weapons and ammunition."

鈻?Observation

Changhong to build "digital Supremacy"

Changhong, China's color TV industry has a pivotal role. During the past decades, Changhong successfully seized the CRT color TV, projection TV two opportunities for industrial upgrading, became the world's second-largest TV company, today Zhao Yong has achieved at flat-panel TVs, whether or not to rewrite China and the world TV industry structure it? Perhaps the recent action from Changhong find the answers.

The new bureau opened flat

With the rise of flat-panel TV market, foreign giants have unanimously thrown their own "plate" strategy, not only the traditional home appliance giant, "rush", even Dell, HP, Motorola, IT, telecommunications companies have to share. On December 20 last year, Changhong has finally unveiled the mystery for everyone.

In the press conference, Changhong was declared fully into the flat panel television, flat panel industry on R & D, manufacturing and marketing policies to tilt towards the world within two years, three flat-panel TV manufacturers, TV manufacturers from a traditional to information appliances, digital media developers of successful transition.

Deputy general manager of Changhong, said Zheng Guangqing, Changhong will take the following aspects of the strategy: First, plans to invest 1 billion yuan for the flat-panel TV technology development; two, seize the trend of 3C integration, the user build a flat-panel TV for the terminal digital home entertainment center; 3, open up the flat industrial chain, and upstream and downstream parts supplier companies to form a strong industry cluster, to play a chain competitive advantage.

To break the blockade Technology

It is understood that flat panel TV is a new development trend of China's color TV enterprises are to achieve a greater development, it must occupy high ground in the field of flat panel TVs.

Changhong promotion of high-profile flat-panel TVs, flat-panel TV is the key technology of capturing the "Golden Triangle plate imaging." It is understood that "flat-panel imaging Golden Triangle" is the world's most advanced flat-panel TV technology, X-power super power chip, five-time intelligence "golden ratio" and the ultra-fine screen in Korea three organic integration, so that Product image quality and sound effects have a breakthrough to improve and effectively overcome the ordinary flat TV brightness is not high, and poorly, trailing "fuzzy" and the fulfillment of 720p, 1080p high-definition formats such as global digital reception. The technology of capture means that Changhong had first broken the blockade of multinational technology so that the quality of domestic flat-panel TV is enough and comparable to foreign brands.

To create a flat myth?

Flat-panel TV is only "digital Changhong," the first step, Changhong ultimate goal is to rely on digital technology, integrated wired and wireless networks, and construct a terminal for the main family TV multimedia information center, to achieve interoperability between appliances to form a fully meet user needs, "digital home", to best satisfy people's growing need for audio-visual entertainment. This is the biggest task facing Zhao Yong.

Industry insiders believe that the current flat-panel TV brand in Japan and South Korea are still dominant, but with the consumer market development and domestic enterprises such as Changhong, research and development, personnel, and funding increase investment, product advantage will become increasingly prominent on the Century 90's expulsion of foreign domestic color TV brands together achieved a major victory for the brand and, ultimately, history may repeat itself.

Flame motion animation in the law

Animated flame is often needed to show an animation phenomenon. Fire can also be divided into: a small flame (such as burning candles, matches burning, etc.), the larger the fire (such as firewood burning, etc.), raging (such as fires, etc) some. In the cartoon, it is common to have three. Here, we demonstrate the greater the fire, in the hope that we can help. I hope you whiskey!

Fire within the flame and the outer flame is formed. No matter how big the fire, the combustion process will be under the influence of flow reveals the strength of irregular movement. But they all have a basic law of motion:

That is, expansion, contraction, shaking up the next collection, separation, disappeared. Flame when the fastest speed at the bottom, the more up more slowly, until the disappearance. The shape of the flame under fire often changes the size and direction.

Here is the screen frame by frame analysis:



This picture is the fire of the first frame, we have to deal with by contract.



This picture is expanded, this time because of air flow, hot air rises, the outer flame and flame out in the expansion of the number of specific expansion, you can plot the needs and design sense to tune up.



Hot air rising within the flame and the outer flame of fire to Shangcuan.



Because of the wind, the fire will be in about the same time to Shangcuan shaking.



When the flame to a certain limit, the outer flame to Shangcuan the same time and the following fire separation, which is separated.

Then the above



Separated from the flame to continue to increase, rising at the same time it disappeared. The following flame that we received it the next. Then and the screen of a formation cycle.

When the fire into the loop of irregular movement rule, and if we do fire when the cycle time longer, then the law can do many different cycles. Thus, the effect of the screen will be changing. Figure 1-6 is a loop, then we can stagger the order. This effect of the screen will be more good-looking!

In general, when designing the raging fire smoke have produced, so the screen will have good results. Have time I will in the future process of making it onto the hair.

Thank you for your support! ! !
