Software Development Practice for FDA-Compliant Medical Devices

Software development in medical devices by implementing lightweight processes in formal regulatory environments is an issue. This paper describes software development practice with the project of Digital Subtraction Angiography (DSA) medical device, and introduces experiences to ensure FDA regulatory compliance In addition, we introduce a hybrid methodology adopted in our software development process which is to use agile method to reduce project risk, and use formal waterfall-like lifecycle to create documents.

A Metadata-based Interoperable Digital Rights Management System Architecture

Digital rights management (DRM) technology aims to distribute digital contents to consumers in a controlled manner that can protect the copyright of digital contents. In order to meet consumer’s expectations, DRM approaches and related services and applications upon which they are based should coexist in an environment that supports interoperability. In this paper, we propose a Digital Rights Management system architecture based on ChinaDRM metadata schema; The approach supports import and export different types of rights license, and also provides the rights transfer capability, so that it can achieve a certain level of interoperability which is proved by a practical distance education project.

Abstract Oil-Painting Using Texture Synthesis

This paper introduces an improved algorithm based on Efros algorithm to create abstract oil painting by selectively copying patches of the source image onto the image to be stylized. Contrast to Efros algorithm, our algorithm provides better computing error optimization; another improvement is to change the direction of searching for a better performance. Experimental results show that our algorithm is faster and the abstract oil painting artistic quality of the resulting image is better.

Generalized Petersen graphs are an important class of commonly used interconnection networks and have been studied . The total domination number of generalized Petersen graphs P(m,2) is obtained in this paper.

The reply and development strategy of cable TV industry in the era of big data

This paper discusses the necessity and importance of the establishment of big data from the current predicament of cable TV industry, and introduces the current situation of the development of big data of Internet and telecommunication industry, and expounds that the cable industry how to deal with and develop big data from many aspects, which ensure that cable industry can have the dominant position in the fierce competition.

Opportunities and challenges of TV media in the big data era

Coming with the big data era, our traditional TV media is under the impact of new media, directly reflect in the loss of customers and a serious decline in advertising. This paper analyzes the main problem television media confronting in the big data era, calls the need for the big data platform of television media to solve these problems, and proposes the general idea of big data platform television media and the big data platform framework of television media.

Radio and television operators cloud computing infrastructure research system

Cloud computing is the product of a traditional classical computer technology, communications technology integration and development, also the key technology to lead information industry means to the future of innovation. This article describes the key technology of cloud computing, reviews cloud computing for industry development status and analyzes the applications of radio and television carrier services, researches how to build a legitimate broadcasting operators cloud computing architecture for supporting the corresponding business applications, how to improve user perception, reducing stress operator core system for enterprises and make cost efficiency.

Analysis on radio and television development

Big data, the word has been mentioned more and more. It is better to say that we are in such an era rather than that the big data era is coming. How to use good data, so that the hands of the data collected into a valuable thing, rather than a IoT of data garbage, is the problem that every industry has been thinking about. Every enterprise wants to seize the opportunity to develop large data, in order to walk in the forefront of the industry, thus becoming the industry leader, bring greater benefits for themselves. This article focuses on some of the existing problems of radio and television and some suggestions for the big data platform construction.

Genetic algorithm optimization research based on simulated annealing

As a kind of mature algorithm, genetic algorithm has been widely used in the field of Artificial intelligence and has played an important role in promoting the development of artificial intelligence technology. This paper analyzes the principle and characteristics of genetic algorithm and introduces an improved algorithm combining with simulated annealing algorithm and genetic algorithm. As an example of solving the TSP problem, this paper analyzes the advantages of the improved algorithm. We will discuss the development direction and prospect of genetic algorithm in the field of artificial intelligence.

The Implementation of Crawling News Page Based on Incremental Web Crawler

Web crawler technology is the technology which downloads web pages through the program. This paper implements incremental Python web crawler, uses Scrapy crawler framework, crawls news web pages from mainstream web sites incrementally in real time, and deposits data in the database. The key technology of incremental crawling is removing the repetition of web links, and the most common method is using Bloom filter. This paper implements a simplified Bloom filter. The result shows that the web crawler can monitor the news pages well.
