In this paper, we manufacture the parallel transmission system consisting of an infrared light emitting diode (LED), an avalanche photo diode (APD) module and a field programmable gate array (FPGA) board corresponding to 132, 540 logic elements (LEs) by way of trial, and evaluate the BER performance of the optical ZCZ-CDMA system with the equal gain combining (EGC) by the indoor experiment. As a result of indoor experiment with the parallel transmission system, BER performance improves with an increase in number of received APD by the EGC.
This paper reports a web-based survey system developed to enhance institutional research. The system has basic functions implemented in the open-source web questionnaire system. In addition, this system has functions that enhance institutional research, such as (1) the display of the response rates of each university department, (2) collation of all results obtained (including paper-based surveys), and (3) an analysis of survey results using visual tools. The design considered the importance of a link-up with the authentication server belonging to Yamaguchi University. Thus, graphs may be compiled automatically and in real time to assist a comparison between departments within the university by respective stakeholders. This work provides an overview and a case study of the usage of this system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
