본 논문에서는 전극칩에서 배양하는 세포의 활동성을 실시간으로 모니터링 하기 위해 AC 함수발생기와 Lock-in-amplifier (SR 830, Stanford Research System)를 이용하여 개발한 LabVIEW(National Instrument)기반 세포 임피던스 측정시스템을 제안하였다. 대장암 세포인 HT-29를 다 채널 전극칩에서 60시간동안 배양하는 동안 LabVIEW기반 세포 임피던스 측정시스템을 이용해서 인가하는 신호의 주파수와 세포의 배양시간에 따른 세포 임피던스 변화를 관찰하였다. 결과 HT-29 세포가 전극에 안착하고 증식하기 때문에 전극의 임피던스가 증가한다는 이전 연구결과와 일치하는 측정결과를 얻었고, 이 결과를 통해서 제안한 LabVIEW 기반 세포 임피던스 측정시스템이 암세포 연구에 적합하고, 앞으로 유용하게 사용될 수 있음을 확인하였다.

We developed the numerical analysis program using LabVIEW for the monte-carlo simulation code for OCT signal in dental medium. In calculation, we obtain the two different signals as a function of the probing depth. These two signals are very different in their angular distributions, and the numbers of scattering in dental medium. Signal 2 begins to exceed the signal 1 at a very small probing depth(=60${\mu}{\textrm}{m}$).

LabVIEW is faster than text language based program regarding development time and can monitor the output of data fast without the separate compiling work as the graphic-based graphical programming language. And, its coding is fast because it is designed by connecting the function with the wire and its has the merit of relatively intuitive UI. In this paper, data transmission and receiving between the program that is implemented in C language as CAN communication method that is strong against noise and used in power electronics application field variously and LabVIEW based program are explained. And, the design of LabVIEW based CAN communication program, data analysis and GUI screen composition that is convenient for monitoring are shown.

In this paper, we developed a green home simulator using LabVIEW for house designers or users to assess energy saving costs in an easy and direct way. The LabVIEW simulator has a strong graphic user interface, which is intuitive to general users. Therefore, the developed simulator enables one to gather information on electric power consumed in its house and to calculate efficiency for installing green energy generators such as solar and wind power generators. As an actual application, we simulate and compare the efficiencies of installing green energy generators at various cities and seasons using the developed LabVIEW simulator. The simulation results confirm that energy saving effects of green energies are easy to calculate by the proposed green home simulator.

This paper presents a gas turbine data acquisition and monitoring system using a LabVIEW programming. The developed real-time monitoring system entitled a C-Tune DAS Plays an important role to make an analysis of the real-time operation of the gas turbine under maintenance. the LabVIEW based software is divided into three parts according to their original functions; Data acquisition, Data analysis and display, and Data storage. The data acquisition part receives data from a PMS (Plant Management System) server and two cFPs (Compact-Field Point). To verify the validity of the developed system, it is applied to gas turbines in the combined cycle power plant in Korea.

A design and analysis program is proposed for switched reluctance motor using an analytical method and a CAD program LabVIEW. The algorithm uses conventional permeance method, in which flux linkages, inductances and torques are calculated numerically. In order to analyze a dynamic characteristics of the motor, voltage control scheme is fallen and a single pulse operation is applied. 2 SRM models are analyzed under the given specifications and constraints. The results compared with measured data.

A wind turbine monitoring system is essential equipment fur the performance evaluation and mechanical load analysis of a wind turbine. A monitoring system using LabVIEW is developed in this study. This system monitors signals from a meteorological mast, wind turbine generator, and tower. The discrete signals which are sampled at t Hz are automatically saved on a data file in the unit of a day. Besides these basic functions, the developed monitoring system has the other several capabilities. One of them is the information access from a remote PC through the internet. A vision image of the test site area and data files that are produced by LabVIBW software can be uploaded to the main computer located in a remote site. An emergency backup system using UPS fur the power loss on the monitoring HW is also prepared, A detail explanation for the developed wind turbine monitoring system is presented in this study.

With the arrival of the fourth industrial era, demand for agriculture is increasing day by day, and smart farm technology, in which computers manage agriculture in line with the current situation, is developing. However, agricultural workers who use it find it difficult to set up and use a management system for smart farms. This paper aims to establish a Lab-View smart farm management system to facilitate the use of a control program for ICT technology farms (hereinafter referred to as smart farms), one of the promising projects of the next industrial revolution. Based on Lab-View, users simply set the type of crops they want to grow, set appropriate temperature/humidity data for each set crop, and collect data in real time through sensors and store it in DB. This functionality maximizes convenience and usability in terms of users.

In this paper, a portable rotor bar fault diagnosis system for small 3 phase induction motors is suggested. For portable real-tine diagnosis system, an USB-DAQ board for collecting the 3 phase current data, three current probes, and a notebook computer are used. The LabVIEW graphical language is used for filtering, analysis, storing, and monitoring the current data. The three phase stator current are filtered and transformed to frequency level by FIT. An analysis window programed by LabVIEW is located in front panel to show the FIT results and this suggested window has a zooming function to detect the fault feature more easily near the feature frequency range which is varying by the slip frequency. To show the possibility of portable rotor bar diagnosis system, three types(healthy, one rotor bar fault, two rotor bar fault) of rotor bar are intentionally prepared and compared by the suggested window of front panel. Experimental results are shown that a suggested diagnosis system is applicable to portable diagnosis system and the rotor bar fault is detected by the frequency window in front panel programed in LabVIEW graphical language.
