Verification of effectiveness of

In monitoring the state of a marine engine, a method

method using lubricant analysis andbecause of its high accuracy of abnormality detection. The

condition based maintenancemachine learning for marine diesel
engineusing lubricating oil analysis has attracted attention

existing method focuses on iron abrasion powder that isconstantly generated during operation, and detects

anomaly from changes iron concentration in the oil. In

this study, we propose a new condition-based monitoring

method that can be for stepwise state estimation and easyborder of setting, which are issues of the existing method,by combining machine learning with the existing method,and verify its effectiveness.

Cooperative Object Transportation
System by Swarm Intelligence

The learning ability of a swarm composed of the Boid
units was studied through a cooperative object

transportation task. A cooperative transportation task ofdifferent-sized objects to the proper destinations placed ina 2-dimensional plane by multiple Boid units was

simulated. Considering Boid units as the cell bodies in an
artificial neural network, the learning algorithm of neuralnetwork was applied to the network of Boid units. As aresult, the network of a swarm had acquired how totransport objects to their appropriate goals by training

vibration fatigue mechanism was clarified by comparing

found that the vibration fatigue of the aluminumelectrolytic capacitor for a vehicle is largely affected by theforce applied from the substrate deformed by thevibration.

Study on decomposition

mechanism of dimethyl sulfoxide

Dimethyl sulfoxide (DMSO) is widely used in chemicalindustries, because of its high dissolving ability and low
toxicity. It is well-known that DMSO is highly stable attemperatures below 150 °C. On the other hand, DMSO
has high energy enough to cause explosion and several
accidents in laboratories and chemical processes havebeen reported. Therefore, it is important to obtain

information regarding autocatalysis and to understand
how we can handle DMSO safety. The purpose of thisstudy is to get better understanding of decomposition
mechanism of DMSO.

phenomenon using a unique method called the probability
density function method. This time, it was suggested that
this method could be used to determine the additive /synergistic effect of the two washing conditions. If thisdetermination is possible, it is considered that more
effective cleaning conditions can be clarified.

Study for the cause of induction
period of H2O2/CuCl2

Hydrogen peroxide is one of the widely used chemicalmaterial. On the other hand, it is so unstable that it

caused many accidents in past. It has been suggested thatwhen mixed with copper chloride, an induction period

occurs. But we didn’t have enough knowledge about thismixed system’s phenomenon. The purpose of this study isto unveil the cause of the induction period in the mixed
system of hydrogen peroxide and copper chloride.
