Research Topics

1. Utilization of disaster wastes as geo-materials
A large amount of disaster wastes were caused by the great east Japan
Earthquake. Compaction, CBR and direct shear tests were conducted on thedisaster waste obtained from several sites at Tohoku region. An innovative
approach by using compost containing Halo bacteria/salt tolerance bacteria
was tested to restore the saline soil.
It was found that the disaster waste has a similar strength in comparison withusual sandy soil. The disaster waste contains organic waste such as wood
Disaster wastes
chip. It was considered that the organic waste will affect on the strength ofthe disaster waste for a long term. It was also found the compost is useful for reducing the excessive salts
from the soil.
2. Geo-environmental improvement techniques using microorganism for sustainable development
Various geo-environmental issues have occurred in regional and global levels. Utilization of wastes andremediation of contaminated soils are examples of geo-environmental problems. When waste material isutilized as geomaterials, it is required to apply any treatment for reducing the harmful substances. From aviewpoint of reducing environmental load, a method with low cost and without using special chemicals isneeded for sustainable development.
A remediation method by using aerobic or anaerobic fermentation is applied. The effect of compostingwith aerobic or anaerobic fermentation was discussed based on the test results. It is concluded that theanaerobic fermentation with organic matter, effective microorganism resources, and leaf mold is very
effective for remedying the contaminated soil with hexavalent chromium.

system identification theories such as Realization theory. Developed techniques make measurement
operations ‘on-line’ by ICT-aided computerized-operations from data collection to showing results ofanalysis. The system demonstrates high accuracy of identification and its practicability throughapplications to the several actual bridges.
A Simple Pavement Diagnostic System Using Dynamic Responses of an Ordinary Vehicle
A simple monitoring system 'Vehicle Intelligent Monitoring System' has been proposed for inspecting
road surface conditions objectively, promptly and inexpensively. The system estimates International
Roughness Index by capturing the vehicle's dynamic response from vertical acceleration. In this study,
VIMS has been introduced for road inspections in some countries.
Image Processing Techniques for Detecting Structural Damage on Surface
New robust automated image processing methods for detecting cracks in surface images of concrete
and asphalt structures have been developed in this study. The mark of this study is the multiple
sequential image filters which are generated by evolutionary computation with genetic programming(: GP). The proposed method can be used for the accurate detection of cracks in surface images
recorded under various conditions. Moreover, the widths of the detected cracks can be quantified on
the basis of the spatial derivatives of the brightness patterns in sub-pixel resolution.

Study on the relation between water quality dynamic andoccurrence of red tide in Isahaya Bay;A big project that consists of the construction of sea-dike andreclamation in Isahaya Bay was completed in 2009. These caused several
environmental problems such as a change in current, eutrophication,oxygen depression and so on. Recently, big damage was given to clamfarming at the outbreak of red tide. However, the hydrodynamic
mechanism related to these phenomena has not been clarified because of
the insufficiency of scientific data. In order to realize the relation between

Development of an approach based on a joint moment generating function (MGF) for stochastic
network calculus. The aim of the study is to provide a new approach based on a joint MGF. For
isolation, many approaches are based on marginal distributions, which lack the information on higher
degree cross moments such as correlations. To capture the effects, we introduce a joint MGF
approach. Recent results have given two inequalities on a generalized effective bandwidth and ageneralized Chernoff bound. They are tighter than that by the previous approaches. Unfortunately, theBoole inequality have never been generalized based on a joint distribution.
Application to a non feed forward networks. The joint MGF approach consists some inequalities
which do not require any statistical independence assumptions. The non feed forward networks
permits a situation that the input traffic sources to a node depends on each other. Here, we have toconsider efficient evaluation methods.

Associate Professor

Field of Specialty
Electric Power/Electric Equipment Engineering

Research Topics

1.

Design of high-efficiency high-frequency switching circuits
basing on analytical approaches
We express the relationships between circuit response and elements assome formulations, basing on circuit theory and combining differential
equations and Fourier analysis, which enables designers to understandthe circuit operations well and design switching circuits easily.
2. Circuit development by taking advantage of software
By using the software, which is a design algorithm developed by Dr.
Circuit experiment
Sekiya, it is possible to obtain accurate design values with high speed.
We take advantage of the software to design complicated switching circuits or propose new-topology ones.

electron

1. Surface modification of materials by ion implantation
Surface modification with ion implantation and analysis ofsurface are studied to give environmental conscious and excellent
mechanical properties to surface of materials.
2. Preparation of thin films by a plasma source ion
implantation
A combined method of plasma CVD and ion implantation by anapplication of high voltage pulse bias to the substrate in a plasma isstudied in order to prepare functional thin films. By the transfer ofthis technology, a coating serves company was established at 2006
in Nagasaki.
