Portable Water Color Monitoring System Using Microcontroller for Phytoplankton Bloom Measurement in Japanese Lake
Ping WANG; Yuko Ishikawa; D.D.G.L.Dahanayaka and Atsushi Minato, Corresponding, Rapid assessment of algal blooms in lakes has been difficult due to lack of inexpensive and portable measurement systems and lack of spatial resolution from current freely available satellites. Here we demonstrate the capacity of a low-cost, portable water color monitoring system in assessing phytoplankton bloom in the Lake Senba, Ibaraki Prefecture, Japan. We developed two types of instruments, one is using three color LED and the other is using small spectroscopic module. The design of these systems and result of fundamental experiment is reported.

Storage-based content distribution is in the spotlight before the boom in digital broadcasting. In 2002, we carried out the research, "Development of satellite based on-demand content distribution systems and verification of effectiveness" which was sponsored by the Information-technology Promotion Agency (IPA). In this paper, the storage-based content distribution service is evaluated from four viewpoints, interest, taste, selection and satisfaction. As the result of the evaluation, most of all generations had interested in this service. The selection of contents is almost the same as one of existing broadcasting. In addition, it was found that the restriction of viewer by IC card and the operability of remote controller were important for the storage-based content distribution service., Japan Society of Kansei Engineering

A New Lighting Communication System for Audio Signal with White LEDS. LIU; A. Minato; S. Ozawa and M. Nakagawa, Corresponding, Light Emitting Diode (LED) is expected as the lighting source of next generation because they are long life, small size, and low power consumption, etc. In previous paper, we proposed a simple visible-light transmission system for sound using white LED. However, the flicker of light is sensed if the transmitted sound signal has the low frequency component. In this study, we propose improved modulation technique to overcome the flicker. LED can transmit audio signal while it is used for lighting source. We verified that it is possible to communicate with the received luminous flux of 1.1×10
-5 lm without flicker. We also evaluated the effects of interference by plural LEDs., The Illuminating Engineering Institute of Japan

We found the forward-bent of patient can be a parameter indicating the mental condition of client. The training was recorded by a digital video-camera. After the training, the forward-bent was measured manually from recorded pictures. In this paper, we reports the application of pattern matching technique to measure the forward-bent. As result of preliminary experiment, it was found that the downward distance calculated by the matching technique and the distance obtained manually are mutually related. In addition, frequency analysis is enabled by this technique. We examined possibility to grasp strain state of mind by frequency analysis, for example, stiff movement by strain of mind, and to be relaxed by change of frequency distribution. We developed a DV camera system in this analysis, but Video capture from a DV camera and conversion work to huge number of still image is necessary. We plan the camera interface connection such as IEE1394or USB2.0 protocol to a PC directly and an image transfer to memory improves efficiency., The Society of Life Support Engineering

Introducing experiments helps understanding, but we don't have enough time for the lecture. We have developed a new teaching technique. The split of two air−packs on the two−dimensional plane is recorded in advance. The air−packs and the sliding plane are designed elaborately to achieve extremely low friction. Displaying and analyzing the recorded picture on the computer, the conservation of momentum is verified by students with enough accuracy.

At first, we defined a concept of 'quality of products' and 'customer's prediction to quality', and modeled 'intension of purchase' and 'customer satisfaction' with them. Next, we analyzed influence of customers' sensitivity to products and technology on 'customer's prediction to quality' and 'intension of purchase' by experiments using questionnaires.

２次元六方晶系モデル結晶における非線形波の伝搬に関する計算機実験ITABA Masanori; MINATO Atsushi; OZAWA Satoshi; HIKI Yosio, Molecular dynamics computer experiments have been carried out for two-dimensional hexagonal mass-spring model crystals. Anharmonic forces up to the third order were taken into account, and central forces were considered between the nearest neighbor (nn) and the next nearest neighbor (nnn) atoms. The ratio of the potential between the nnn atoms to the potential between the nn atoms was varied. An input pulse displacement was given to central atomic planes in the crystal or to the end atomic plane of the crystal, and induced displacements and velocities of all atoms were computed. Solitons were produced as the atomic excitation, and the propagation velocity and the strength of solitons were enumerated. Two crystallographic directions were taken for the input pulse direction, and the values of the nnn interaction parameters were widely varied. As the nnn interaction was enhanced, the soliton velocity increased and the soliton energy decreased. The results were compared with those of 1D, 2D and 3D crystals obtained previously. Discussions and remarks are presented for these results., Society of Computer Chemistry, Japan

授業イメージアンケートによる高専の情報科目における授業分析方法の試みFuse Masahiko; Minato Atsushi; Ozawa Satoru, The classes we teach daily are numerous and go by so quickly that we may have questions as to how meaningful each session was for students or whether there are students worrying that they may not have fully understood the content. It is sometimes difficult to detect problems of individual students during the class, and often some students may have fallen by the wayside by the time we become aware of the problem. To cope with these problems, we developed a system helping the students of the college of technology study "the information processing". We utilized networked computers to gather questionnaires about the contents at the end of each class. The analysis of the result for each course was carried out individually. We also developed a support system for extracting the feedback for following sessions. We have used this system in the course of "the information processing" for 2 years. In this paper, we discuss the results of analysis and the effect of our method., CIEC

Propagation of errors in a measured spectrum was studied analytically. The result shows that the systematic error in the determined concentration depends on the type of the noise included in spectral data and it is important to use appropriate weighting function in least square fitting for minimizing the error. Optimization of measurement conditions was also investigated by the analytical method., The Spectroscopical Society of Japan

ADEOS搭載リトロリフレクター(RIS)の設計(共著)湊 淳; 杉本,笹野, Lead, This paper describes optical design of the Retroreflector In-Space (RIS) for the Advanced Earth Observing Satellite (ADEOS), which is planned for launch in February of 1995. RIS is a cube-corner retroreflector for earth-satellite-earth laser longpath absorption measurements of atmospheric trace species such as ozone, CFC 12, carbon dioxide and methane. In the RIS measurement, a laser beam is transmitted from a ground station, reflected by RIS and received at the ground station. The absorption spectrum of the atmosphere is measured by scanning the laser wavelength. The density of the trace species are obtained by analyzing the spectrum. RIS has a single-element hollow structure and has an effective diameter of 0.5 m. The mirror shape for RIS was newly designed to optimize the intensity pattern of the beam reflected by RIS in orbit. A slightly curved surface is used for one of three mirrors forming the retroreflector to overcome the velocity aberration of the reflected beam. The effect of the curved surface on the intensity pattern of the reflected beam was investigated by a computer simulation. The parameters of the surface curvature were determined by optimizing the reflected beam intensity at the ground station., The Remote Sensing Society of Japan

Multiple Wavelength Laser Radar for Measuring the Stratospheric and Tropospheric Ozone ProfileSUGIMOTO Nobuo; SASANO Yasuhiro; NAKANE Hideaki; HAYASHIDA-AMANO Sachiko; MATSUI Ichiro; MINATO Atsushi, Last, A multiple wavelength differential absorption laser radar has been constructed to measure the ozone profiles from the lower troposphere up to the upper stratosphere. The system consists of two subsystems ; one (the low altitude system ; LA) for the tropospheric measurements and the other (the high altitude system ; HA) for the stratospheric measurements. The LA system employs a KrF excimer laser with a deuterium and a hydrogen Raman shifter to generate 277, 292 and 313 nm laser pulses, and a receiving telescope with a diameter of 0.56 meter. The HA system has a XeCl laser with a deuterium Raman shifter and a XeF laser to generate 308, 339 and 351 nm laser pulses, and a receiving telescope with a diameter of 2 meters. The whole system is controlled by a mini-computer. Details of the system and some measurement examples are presented., The Japan Society of Applied Physics
