Temperature monitoring techniques per depth have been recognized as important information in the reservoir environmental issues. However, old measurement method by single temperature sensor and cable type has demerits not only for its limited measuring location but for its inconvenience of users. In this study, multi-channel temperature monitoring system was introduced and executed experiment for actual application feasibility evaluation. Both type of new techniques such as multi-channel addressable built-in temperature sensor and fiber optic multi sensor were tested in Daechung and Imha reservoir. As a result, it was proved that these kinds of temperature monitoring skills had very good performance and availability for a output of spatial, simultaneous thermal distribution focused on the user's convenience. And these measuring method and thermal data will be useful for providing basic information in a water resources investigation like reservoir stratification and environmental problems.

Monitoring of water surfaces through permanent measurement of hydrodynamic and meteorological data is one of the main requirements in safe and sustainable water management. The Caspian Sea, the major surface water body in Iran, significantly affects more than 600 km of urban and industrial coastline. In the present work, an integrated marine monitoring network for the entire southern coastline of the Caspian Sea was developed. The main design concerns centered on the network measuring components and data recording, checking, filtering, gap recognition, and transferring systems. Four coastal monitoring stations were assigned, along with two regional collecting stations and one central data station for gathering, checking and delivering recorded data at different access levels. Applicable guidelines on selection of measuring devices for both shallow and deep water zones are presented herein.

Smart Pole Measurement System was constructed with not only the core sensors of a GNSS receiver, a TRS sensor and a soil moisture sensor but supplementary installation of power supply and radio communication for monitoring steep slope sites. Also a data processing software for displacement extraction and visualization was developed. Smart Pole Measurement sensor is composed of a GNSS antenna at the top of the pole, a TRS sensor and a gyro sensor vertical below right of the antenna and a soil moisture sensor at the bottom of the pole. The sensor combination extracts not only ground combination in real time but transltion, slide, settlement and soil moisture content. This measuring/monitoring system which cosists of data receiving part, data collection/transfer part and data processing part was built to exercise their functions and then test measuring/monitoring was conducted by introducing artificial displacement and the results were analyzed to evaluate field applicability.

Technologically advanced railway countries had a unique ability to design, test and evaluation systems for development of High-speed train system. To evaluate the performance of the train system in Korea for the development of advanced measurement technology and systems are needed. In this study, the Overall Measuring System(OMS) is going to be established to efficiently verify the performance, stability and reliability of the train system and the components, and verify of the maximum speed though an on-line test. OMS consist of vehicle measuring system, pantograph measuring system, video monitoring system and monitoring room was constructed for the overall measuring system and monitoring system. The results of this study were expected to contribute to technical improvement for evaluation of train system.

In this paper, we introduce the software of the measuring system for on-line test and evaluation of high speed rail. This software should set and control the hardware of the measuring system, perform the analysis and calculation of measuring data and interface between users and the measuring system. For this purpose, three programs, such as a measuring program, a monitoring program and post-processing program, have developed.

This paper describes a sensor-based remote monitoring technique for ship block assembly and implementation of a prototype system. Instead of manual processing or optical measuring devices, the proposed approach attaches some distance-measuring sensor nodes to ship blocks. Remote monitoring of the assembly status makes it possible to minimize marginal errors during ship block assembly process, and helps efficient ship building.

Condition monitoring technique used in the military is JOAP, for which the spectroscopic analysis is applied. However it is known that the technique has some problems in economical and practical point of view. This study introduces a new technique for measuring wear in real time base and applies the technique to a high power semi-automatic transmission. The results show the feasibility by measuring the concentration of ferrous wear particles from the transmission oil.

In this paper, we analyze the operations and/or status of our structure which builds the management structure measuring integrated monitoring system based on linked open data in a short term or long term bases. We have applied a novel analyzing method of linked open data to expect what movements can be occurred in the structure, and we improve the monitoring system using an integrated design to solve the drawbacks of conventional types of monitoring. And collecting data through cloud and their reliability can be proved by evaluation of soundness of data amount and their confidence.

In this paper, a PC-based virtual measuring program for efficiency analysis of DC-DC converter is developed. Furthermore, a newly developed, highly accurate and reliable data acquisition system for DC-DC converter is presented. The virtual measuring system consists of two different types of monitoring and measuring system. Also, this paper give a full explanation for a LabVIEW realization of the measuring system for DC-DC converter.
