Practical Teaching

Practical training plays a significant role in engineering subjects. In communication engineering, most of universities provide communication test cabinets or simulation software for practical training. These can make students understand the basic principles of local modules, while cannot provide a whole view of communication systems. Our work constructs a practical training project of telecommunications experiential platform, consisting of hardware communication facilities and software operation systems, realizing multi-user operating practice. This telecommunications experiential platform can train more than 40 students simultaneously and has proved to be economic and efficient in practical teaching.

Abstract Although students may not become augmentative and alternative communication (AAC) clinical specialists, they often will work with individuals demonstrating complex communication needs who benefit from AAC. This necessitates knowledge of some basic principles of assessment including AAC assessment as a team process involving planning and implementing interventions for current and future communication needs; the inclusion of no-tech, low-tech, and high-tech communication systems; and assessing communication needs with partners in the individual's social network. The assessment also must include a capability profile and feature matching to select the appropriate components of the AAC system. Because the system we provide for today will become the system we use tomorrow, assessment must be considered an ongoing process throughout the lifespan of the individual.

The Subject

This chapter deals with roles and ways of interorganizational communication systems. Prior to the subject, author refers to three topics related to the subject: what are interorganizational relationships, strategic alliances, and interorganizational networks. In order to understand interorganizational networks, the author utilizes Barnard’s theory of cooperative system and formal organization, in which communication plays a significant role to formulate and to maintain interorganizational networks as organization of organizations. Furthermore, there are some problems for effective interorganizational communication systems – both human and machine: standardization of communication systems, impact of IT development, and interorganizational strategy using IT.

Uwb Applications

Ultrawideband (UWB) antennas are of huge demand and Vivaldi antennas as well as the TEM horn antennas are good candidates for UWB applications as they both have relatively simple geometry and high gain over a wide bandwidth. The aim of this study is to design a compact antenna that achieves maximum gain over a bandwidth between 1.5 and 10.6 GHz while minimizing its size. The idea is to make use of combined respective advantages of Vivaldi and TEM horn antennas to achieve the desired goals by shaping the TEM horn antenna to look like a Vivaldi antenna. The antenna structure is modified by a dielectric load in the center to increase the gain bandwidth. It is placed in a surrounding box made of PEC material to reduce the undesired side lobes and to obtain more directive radiation pattern. The simulations are performed by using the CST STUDIO SUITE electromagnetic (EM) simulation software and they are later verified by the actual measurements. The Vivaldi shaped partially dielectric loaded (VS-PDL) TEM horn antenna is proposed as a compact UWB antenna for systems using the newly established UWB band and also for the communication systems of popular bands like ISM, Wi-Fi, and GSM.
