This paper describes an approach of composing music with multiple AI composers. This approach enriches more the creativity space of artificial intelligence music composition than using only one composer. This paper presents a simple example with 2 different deep learning composers working together for composing one music. For the experiment, the two composers adopt the same deep learning architecture of an LSTM model trained with different data. The output of a composer is a sequence of notes. Each composer alternatively appends its output to the resulting music which is input to both the composers. Experiments compare different music generated by the proposed multiple composer approach with the traditional one composer approach.

Android Application Package (APK) is vulnerable to repackaging attacks. Therefore, obfuscation technology was applied inside the Android APK file to cope with repackaging attack. However, as more advanced reverse engineering techniques continue to be developed, fake Android APK files to be released. A new approach is needed to solve this problem. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a cryptographic hash of theprevious block, a timestamp and transaction data. Once recorded, the data inany given block cannot be altered retroactively without the alteration of all subsequent blocks. Therefore, it is possible to check whether or not theAndroid Mobile APK is forged by applying the blockchain technology. In this paper, we construct a discrimination DApp (Decentralized Application) against forgery Android Mobile APK by recording and maintaining the legitimate APK in the consortium blockchain framework like Hyperledger Fabric by Composer. With proposed DApp, we can prevent the forgery and modification of the appfrom being installed on the user's Smartphone, and normal and legitimate apps will be widely used.

The methods or algorithms which can accelerate simulation speed became of great importance, as the modeling and simulation methodology for discrete event systems is used in many areas such as model validation/verification and performance evaluation. This paper proposes a tool named, DEVSIF composer. The tool is made of an automated compiled simulation technology and it builds a new composed model which can be executed much fast by composing the component models together. Models are described by our new specification language DEVSIF, which is compatible with object-oriented language and supports representation of a hierarchical model structure. Experimental results demonstrates that DEVSIF composer enhances the simulation speed of a transformed DEVS model 5 times faster than that of the original ones in average.

In a recent year, the broadcasting system has been changed from analogue to digital all over the world, not just in Korea, and Korea aims at accomplishing 100% digital broadcasting by 2013. The HD(High Definition) Video Format, which currently plays a key role in digital broadcasting system, has been gradually extended in the field of broadcasting and movie. Additionally, many kinds of camcoders and editing systems have been rapidly converted into the digital types, and they are supporting to photograph and video editing systems with the various types of image formats such as SD(Standard Definition) format, HD format, 2K, 4K, etc. Tape Video Storage System, which has been usually used in the stage of photographing by this day, is gradually evolving into Tapeless Video Data Storage System. Thus in this study, Video Compression method of HD format photographed by Sony PMW-EX3, one of major tapeless camcoders, is studied and also the way of applying it effectively in Avid Media Composer, a non-linear editing system, is discussed.

XML can effectively express structured or semi-structured data as well as relational databases. XQuery is a query language for retrieving information for such an XML document. In this paper, an XQuery composer is designed and implemented, with an API provided for XQuery processors, and a proper processor is registered. This composer shows query results immediately processed by the processor. As this composer contains a parser for XQuery, it can compose XQuery effectively using a diverse dialog box designed for XQuery grammar. A dialog box is affiliated with a clause region, which is a region that algebra operates from the parsing tree. It can compose path expressions for an XML document easily as it shows an element tree from DTD graphically. Path expressions are composed automatically by marking elements in the structural hierarchy and by specifying the predicate of an element partially.

A component is a reusable and replaceable software module accessed through its interface. Component-based development is expected to shorten the development period, reduce maintenance costs, and improve program reusability and the interoperability of components. This paper proposes a new robot software component platform in order to support the entire process of robot software development. It consists of specifications of a component model, component authoring tool, component composer, and component execution engine. To show its feasibility, this paper presents the analysis results of the component's communication overhead, a comparison with other robotic software platforms, and applications in commercial robots.

본 논문에서는 다양한 촉감 구성 요소들을 조합하여 촉감 정보를 생성하는 촉감 조합기를 개발하고, 개발된 촉감 조합기를 인스턴트 메신저 기반의 촉감 공유 시스템에 적용하였다. 촉감 공유 시스템은 촉감의 시각적 정보를 담고 있는 배경 이미지와 그 위에 기록되는 촉감 정보를 관리하는 촉감보드를 원격지의 사용자와 실시간으로 공유하는 환경 공유 시스템이다. 본 논문에서는 촉감 공유 시스템을 최근 인스턴트 메신저 서비스에서 제공하는 간단한 플러그인 형태로 개발하였다. 따라서, 본 시스템을 위해 개발된 촉감 조합기는 사람의 촉감 정보를 구성하는 주요 요소들만으로 간단히 정의하고, 생성 및 편집, 공유를 목적으로 설계하였다.

시멘틱 웹 서비스의 최종적인 목표는 네트웍으로 연결된 프로그램들과 장치들이 사람의 명령 없이 긴밀하게 상호작용 하는 것이다. 시멘틱 웹은 정보의 의미를 알 수 있는 프레임워크를 연구하였는데, 이는 인공지능을 기반으로 하는 RDF. RDFS, DAML+OIL, OWL등의 언어를 기반으로 하여 연구되었다 시멘틱 웹 커뮤니티에서는 웹의 정보 뿐 아니라 서비스에도 정확한 의미를 부여하기 위해서 DAML+OIL 온톨로지 기반의 새로운 기술인 DAML-S 온톨로지 기술을 제안하였다. DAML-S는 Service. Service Profile. Service Model. Service Grounding의 4개의 상위 온톨로지로 구성되는데, 특히 Service Profile, Service Model 온톨로지와 인스턴스를 이용하여 사용자의 요구에 적합한 서비스 검색과 Composition01 가능하다. 사용자의 요구가 atomic 서비스가 아닌 여러 atomic 서비스들을 함께 이용해야 하는 경우에는 시멘틱 웹 서비스 검색 시스템 외에 추가적인 웹 서비스 Composer가 필요하게 된다. 본 논문에서는 사용자의 요구로부터 필요한 웹 서비스 chain을 구성함에 있어서 사람이 개입하지 않는 STRIPS 타입의 자동 웹 서비스 Composer를 제안한다.
