When the cylindrical wave is incident on a plane dielectric interface from a denser medium to a rarer one, the asymptotic solution for the transmitted wave in the near region is different from the one in the far region. In this paper, we have derived a novel uniform asymptotic solution represented by using the parabolic cylinder function for the transmitted and scattered waves observed in the rarer medium when the cylindrical wave is incident on the plane dielectric interface from the denser medium. The validity of the uniform asymptotic solution has been confirmed by comparing with the reference solution calculated numerically. It has been clarified that the transition wave plays an important role to connect smoothly the asymptotic solution in the near region to the one in the far region through the transition region. We have shown the very interesting phenomenon that the lateral wave type transmitted wave is observed in the far and shallow region.

In this paper, we analyze the blocking probability of a call in a PC communication network. In a PC communication network, a call generated from the PSTN (public switched telephone network) requests the connection to the ICPS(information communication processing system) which interconnects the the PSTN and the PSDN(packet switched data network). Then, as a second step, a packet call is requested to the specific service database attached in the PSDN. The call blocking probabilies are analyzed for these two interface points, the PSTN interface ports of the ICPS and the PSDN interface link of the database. We also present some numerical results to show the effects of the system parameters on the performance of the network. The results show the effects of the capacity of each interface point on the performance point.

Most of software developers use the GNU Debugger (GDB) in order to debug code execution. The GDB supports a remote debugging environment through serial communication. However, in embedded systems, the speed is limited in the serial communication. Due to this reason, the serial communication is rarely used for the debugging purpose. To solve this problem, many embedded systems adapt the JTAG and the USB interface. This paper proposes debugging environment via USB-JTAG interface to debug the EISC processor, and introduces how the USB interface works on the GDB and how the JTAG module handles debugging packets.

With the advent of the Fourth Industrial Revolution, many companies are developing Smart Ships to enable autonomous navigation, unmanned operation, and cost-effective shipping. In order to facilitate the operation of these Smart Ships, significant emphasis is being placed on improving external communication capabilities and developing autonomous navigation systems. Moreover, unmanned ship operation necessitates replacing of all visually observed conditions with sensors, leading to an inevitable increase in the number of sensors and actuators compared to traditional methods. However, in South Korea, the communication network for sensors and actuators primarily relies on the conventional 1:1 hardwired wiring, with the use of higher-level communication networks when necessary. Therefore, in this paper, we introduce the AS-Interface protocol, which is used for monitoring and controlling sensors and actuators, with the expectation that it will greatly contribute to the development of future Smart Ships by reducing production time, costs, and maintenance duration.

This paper defines the electrical interfaces and limited items to integrate Ka-band communication payload on the satellite system, which includes the detailed interfaces such as bus voltage and data bus according to the related COMS requirements. And the BUS Electrical Interface Simulator introduces to use during the course of validating and accepting between the KA-Band payload and their EGSE. These interface design results are fully validated through the testing with the BEIS and is compliant with the satellite interface control interface requirements.

Google's android-based voice interface is limited to the web application and the users are rare. In this paper, We suggest the method that can be done using existing android-based voice engine and develope voice application. We also study the environments of android-based voice interface and present the appropriate voice interface in mobile environment.

In the digital media era, coded and non-coded communication are used to convey the message. As the computer interface has been adopted human communication methods, non-coded communication has bee used in the computer interface as well. The changes of message structure in the computer interface have an effect on shifting the way of user's message acceptance from passive to active. The recently developed computer user interfaces are for user to experience diverse visual effect The communication conveyed with this visual effects could be vague but user can conceive strong impact. This experience is understood not only through the visual experience from a monitor screen but also with a sense of tactile. The meaning of sensual and spectacle motion image could be ambiguous. However in the experience of using an interface, it plentifully expands the human sense by giving a visual experience on a whim. The sensually extemporaneous and splendid visual effect that has vague meaning has been very common happening in digital media environment.
