IMA NEWS - Mar. 2002

Motto : We challenge risk boldly, deduce conclusion rapidly, create new
business chance and contribute to revitalization of Japanese economy.

IMA (Institute of Mathematical Analysis) news is delivered every month. 

Ｒ&D in Our Institute

The other day, a person called me. Unfortunately, the author was out,
and one of his families replied the phone call. The person asked if there is
brochure of our institute. Since the institute does not sell goods or meet
many unknown people, there was no big need for such a brochure. The
author thought the homepage may be a substitute. However, there was no
appropriate description on the homepage. So, he decided to make some
explanations helpful for such a purpose. The results are shown in Figures below.

Jobs in February

(1) Proposal for practical use of an Underground GPS (Especially on signal
sources)
(2) Proposal for R&D of a high sensitivity GPS
(3) Proposal for practical use of a high precision GPS receiver (collection of
information in US)
(4) Basic study on modulation and demodulation of communication
(Application of wavelet)
(5) Preparation of a paper presented at UT2002 (April, Tokyo)

Essay: Surprising ideas

In the previous IMA news, the author wrote that he attended NTM
(National Technical Meeting) of ION (Institute Of Navigation) held at San
Diego, California, USA and made a presentation on Underground GPS. He
also wrote that he was astonished by a presentation on an application of GPS
technology to an unmanned vehicle on Mar’s surface.

The author has been studying GPS for several years, but, unfortunately,
his research is always one step behind and he feels it a regret. He would like
to make an original proposal in ideas at least. He would like to surprise
researches in US. How enjoyable it would be if succeeded! The author wrote
this kind of nonsense in the previous IMA news.

Then, the author thought following ideas. How about space seismology
or planet seismology! For example, it investigates the internal structure of
moon, Mars etc. by measuring vibration of the ground caused by artificial
earthquakes. The positions of the seismometers and epicenter of the
earthquake are measured precisely by GPS technology using pseudolites.
Very valuable scientific data may be obtained.

Another idea is an airplane flying in the atmosphere of Mars. The
gravity of Mars is 0.38 times that of earth. The atmospheric pressure is 1/200
of that on earth surface. Although the atmosphere is very thin, it may be
possible if the fuselage weight is reduced and the wing area is increased very
much. Something like a butterfly. The airplane may be able to move around
very fast. So, it will collect data in much wider area than a vehicle.

The author thought these ideas are quite unique. However, the former
idea has already been performed on moon. And with regards to the latter
idea, Australian people have recently developed a flying object used on Mars.
There are many unique people in the world!
