To develop a safety-critical network in nuclear power plants that puts more stringent requirements than the competitive commercial ones do, we establish four design criteria - deterministic communication, explicit separation/isolation structure, reliability, verification & validation. According to those design criteria, the fundamental design elements are chosen as follows - a star topology, point-to-point physical link, connection-oriented link control and fixed allocation access control. After analyzing the design elements, we also build a communication architecture with TDM (Time Division Multiplexing) bus switching scheme. Finally, We develop a DDCNet (Deterministic Data Communication Network) based on the established architecture. The DDCNet is composed of 64 nodes and guarantees the transmission bandwidth of 10Mbps and the delay of 10 msec for each node. It turns out that the DDCNet satisfies the aforementioned design criteria and can be adequately utilized for our purpose.

This paper is to study and design a generic electronics system for a meteorological buoy. It mainly covers the communication methods of a buoy with base station, data post processing and power design of a generic weather buoy system. The experiment result shows the design is capable to works well in term of data receive from buoy at base station, battery life time and able to work standalone without any power exhausted problem.

Culture is the soul of tourism, and communication is the key to the inheritance and development of tourism culture. Therefore, culture and communication are essential for the development of tourism. Digital media art is a new form of art that combines technical, artistic, and media-oriented elements. Its artistic expression and crossover communication capabilities drive its usage in cultural tourism communication. This paper examines the influence of digital media art on tourism culture communication and development by elucidating the concept and characteristics of tourism culture communication and digital media art, applying the theoretical knowledge of communication, and deriving the specific characteristics of digital media art on tourism culture in terms of the transmission-reception relationship, content, medium, and effect. The role and value of digital media art in disseminating and developing tourism culture are discussed. We aim to provide valuable insights for the dissemination of tourism culture.

The military communication equipment is required the high reliability for operating adequate functions under severe conditions. This reliability is the essential element for the quality of the product, for the uncontrolled factors, such as the clearance, damage of the material, the reduction of stiffness, which are the designer is unable to handle. In this paper, the uncertainty for the design was supposed to the probability model for the military communication equipment, and the average of the objective function was minimized for reducing design uncertainty. The reliability-based design optimization which was implemented the limit state function was formulated into the mathematical model, so the reliable optimized structure was implemented than the base-line design.

The stage space in theatre for the performance of a play requires two aspects of the physical space for a play and the image as the background or the theme of a play. This research focuses on the scene design that creates the background or the theme of a play and communicates it to the audience. The scene design is composed of various design elements of space and objects as the properties of a play. Design elements and the objects are the design languages in various form; plane, three-dimensional, multi-dimensional form. These design language have the significant meaning as a sign like human language. The scene design is completed with rhetorical expression for communication in theatre. This research defines the category of meaning that design elements of scene design can create and the rhetorical expression of the scene design language. King Lear directed by Robert G. Anderson was analyzed with the category of design elements as a sign and the pattern of the rhetorical expression. The scene design for a play is completed effectively by the rhetorical expression of design elements as the design language for communication with the audience in theatre.
