In the processing of video image data, the data need to be stored and
transferred to other functional units in or out of the system in real time.
Especially in a complex system, it needs a special platform to store and
transfer video image data in real time. This article presents a design of
video image’s storage converter based on FPGA. This storage converter
can convert the video image data format. Its storage density is
very high. It can communicate with personal computer, functional u-
nits in the system and functional units in other systems. The storage
converter can also ensure the real time of video image data.

Social networks can be modeled by graphs with nodes and edges, and
communities are sub graphs within networks. This paper proposes a
new dynamic algorithm based on the modularity given by Newman and
Girvan (NG modularity for short ). Further more, this paper applies
the proposed algorithm to real network data. The experimental results
show that our algorithm can dynamically detect communities in a network,
and the communities detected with the algorithm fits better with
the real communities.

Crawling strategies of web crawler affect not only the quality of search
engine, but also the working status of web server. Many web servers
restrict the access of unknown crawler or the crawler with excessive
visiting frequency. This paper analyzes these restrictions and proposes
a strategy of proxy-based, login by simulating verification code automatically;
give some guidance on the design of web crawler.

Estimate Method to Solve the Time Lag of Sintering Forecast, pp.359–
361
Zhang, Tao

Sintering end control systems generally lag, if the destination ahead
of sintering, the sintering time is too long, sintering heat, so less than
the blast furnace sinter production of each component content. If the
backward end of sintering, sintering not fully carried out, part of the s-
intering machine in the ring on a cold, cold cooling ring less than the
required temperature, resulting in sintering temperature as the feed belt
to blast furnace burning, leading to the back process can not proceed.
Using estimate method to implement burn-through point forecast can
be a good solution to this problem.

In so many combinatorial optimization problems, Job shop scheduling
problems have earned a reputation for being difficult to solve. Genetic
algorithm has demonstrated considerable success in providing efficient
solutions to many non-polynomial-hard optimization problems.
In the field of job shop scheduling, genetic algorithm has been intensively
researched, and there are nine kinds of methods were proposed
to encoding chromosome to represent a solution. In this paper, we
proposed a novel genetic chromosome encoding approach, in this encoding
method, the operation of crossover and mutation was done in
three-dimensional coded space. Some big benchmark problems were
tried with the proposed three-dimensional encoding genetic algorithm
for validation and the results are encouraging.

Application of Ontology Intelligence Search Engine based on Ant
Colony Algorithm, pp.374–378

As the search efficiency is not high and it’s difficult to find user’s interested
information, this paper proposes the combination of ant colony
algorithm and ontology to create search engine. By the clear formal
specification of body shared concept, the search engine has intelligent
search features, and then it can use ontology to provide users’
interested search results. In the process of ontology’s usage, in order
to make different ontology interoperate, the paper introduces similarity
computing, and then improves it. Based on the characteristics of
ant colony algorithm, it introduces multi-pheromone to change search
engine strategy, so it can improve search engine efficiency. While the
multi-pheromones apply to different servers, with the increase of search
times, it can make the finding of best path more effective.

This article has introduced a meal-ordering system based on ARM9,
WINCE, wireless technology, which is both cost-effective and convenient.
It can conquer the shortcomings now exist in the current system.
The system we designed has a user-friendly colorful interface and is
universal. Customers no longer need a servant while ordering and can
communicate directly with the counter. Restaurant will be able to enhance
its overall image and core competitiveness in the catering industry.

This paper concentrates on the evaluation system of hot topics in the
online news about the emergency events. First, the overall technology
framework of the system was established and description was formulated
on the key issues need to be resolved prior to the evaluation of
the hot topics. Focusing on the vector representation of the news documents
and clustering algorithm of the news topics, a modified TF-IDF
text representation model was formulated and an improved selection
method of initial topic clustering center was established. The evaluation
model of the hot topics was then established to evaluate the heat
value of the clustered topics based on extracting websites feature parameters,
such as the time properties of the news reports, reporting
properties, and user attention. Finally, the paper takes news of 2011
Japan Earthquake as data source for algorism and model evaluation.
The results showed that the identification and evaluation system of hot
topics in online news about the emergency events was valid, and the
evaluation result of hot topics by the systems agreed with the expected
results. It lays a foundation for the subsequent studying about the
tracking and evolution of the hot topics.
