Abstract: Archaeological remains of the Iranian culture show the rich culture and traditional arts in this country, which is derived from the ancient Persian traditions and commandments of Islam and attends to all of aspect of human life. Dining table is one of the home key products that gathers family members up, in order to keep intimacy among them, whether there is any sign of tradition and culture of the Iranian-Islamic, and it has setting ergonomic problems. This paper has came out of the practical studying in the furniture designing domain and is trying to cover the gap of presenting of Iranian art and culture in current designing of furniture market. By making use of library as well as field research, by employing interaction design principles using questionnaire, personal interview and observation manners, design criteria are obtained and finally, the premier design with details is presented.

Abstract: What can mean Iranians life, is identity thats comes from their rich culture and its roots refer to native Iranians customs and Islam commands. Family in Iran is the basic and main element in the society that because of keeping Iran identity and culture, should attention to its essential requires. Keeping close and effective relationships among Iranian family members can be achieved by designing recreational spaces for spending Leisure. The main purpose of this paper is designing urban furniture for families resting and serving a meal in the urban space. Unfortunately in the current product there is not any sign of Iran-Islamic costume and culture. By making use of library as well as field research by employing questionnaire, personal interview and observation manners as interaction design tools, design criteria are obtained and finally, the premier design with details is illustrated.

Abstract: This article uses the shared "natural" property of the fractal geometry to analyze the style and decorative arts of traditional furniture so as to help furniture designers apply their new design approach to abroad practice of furniture design, which will develop a new field for creating new furniture forms and decorative patterns.

Abstract: The graphic ad is to convey the theme accurately and clearly with its own unique graphic language. The unusual graphic display is an effective way for graphic creativity and expression. This paper analyzes and discusses the influence and significance of the unusual graphic display on the graphic ad design with some creative methods, such as correlation method, similarity method, contradicting method, multi-angle graphic expression method. etc.

Abstract: Comparing to the single aperture imaging system, Artificial Compound-Eyes (ACE) imaging system has some nice features, such as small size and stereo vision. This paper introduces our multiple-focus ACE imaging system. The system mainly consists of (a) a micro-lens array fabricated by Micro-Electro-Mechanical-System (MEMS) technology, (b) a CMOS chip, (c) a 3D mechanical moving stage, and (d) an auto-focus software module. It can simultaneously observe the object by several channels with different focus, therefore the focal length of the system can be adjusted by selecting different channels. Besides, a software module is developed to carry out auto-focus. The system is applicable to the fields of industry inspection, bio-medical imaging and robot vision.

Abstract: With the establishment of more and more management information systems in the enterprises, many heterogeneous databases have been produced, resulting in the phenomenon of the information island. This paper puts forward a method based on ontology to integrate the heterogeneous databases and presents the framework of the integration method. In this framework A method based on relational database is presented to build the mixed ontology structure Common VocabularyLocal Ontology. The mixed ontology structure is used to establish the semantic web for enterprises. This novel approach exploits the multithreading combined with semantic web to implement parallel retrieval on an integrated platform. The application that this prototype system of the integration method has been implemented in a research institute verifies the method could effectively analyze the user's intention, thereby improving the reuse of knowledge.

Abstract: The basic structure of Cable Digital TV Head-end System is presented in this paper. Cable Digital TV Head-end connected between the TV Signal Source and the Transmission Line is a system which can convert a variety of signal sources into a transport stream to meet the exacting standards of the transmission. The transport streams will finally be sent to service terminal by the transmitting device and the existing network. This paper gives the method of constructing Cable Digital TV Head-end System and some useful suggestions about the selection of equipment.

Abstract: The investigation which involves the respondents privacy is hard to ensure the information security. To rectify this problem, Based on Homomorphic Response Protocol (RRPBH), a novel protocol using homomorphic encrypted system is proposed in this paper. The RRPBH uses the Paillier encryption algorithm to encrypt respondents answer. Paillier algorithm has the good properties of additive homomorphism and mixed multiplicative homomorphism. We can effectively compute the sum of respondents answer with better privacy protection by this protocol.

Abstract: The main research content of this article is to design a direct sequence spread spectrum communication system based on software radio technology. In this paper, design of spread spectrum receiver system directly to intermediate frequency sampling signal processing, after internal processing directly output transmission baseband signal information.

Abstract: Knowledge contests, curriculum evaluation and other activities need to use item bank subject selection system, but such software on the market is less, and the softwares function is often vary with the user's actual demands. Considering the widely use of PowerPoint software in practical work, the design and development of subject selection system based on PowerPoint software are extremely convenient and practical, but its interactive function is not strong, it is difficult to make subject selection intelligent and interactive. In this paper, the PowerPoint software is taken as a development platform, the VBA technology custom solution is used to design and develop intelligent interactive subject selection system.
