This week Toyohashi Tech publishes the June 2012 issue of the e-Newsletter. The issue includes ‘Research Highlights’ — easy-to-understand summaries of some of the top papers from researchers at the university — as well as news and views from one of Japan’s most dynamic science and technology based universities. Direct inks to the relevant articles can be found below.
Digital generation of true random numbers for computer security:
------------------------------------------------------------------------------------
http://www.tut.ac.jp/english/newsletter/research_highlights/research01.html
The generation of true sets of random numbers is critical for secure computer system networks. Here, Hisashi Hata and Shuichi Ichikawa describe the design and implementation of TRNG from fully digital circuits by exploiting the metastability the RS latch.

Monitoring health of milk cows:
----------------------------------------
http://www.tut.ac.jp/english/newsletter/research_highlights/research02.html
The mass production of high quality milk necessitates routine monitoring of the health of dairy cows. In particular, monitoring the pH, electrical conductivity, and temperature of the rumen would enable precise control of the feeding system to optimize the stomach conditions.
Here, Masato Futagawa and colleagues at Toyohashi University of Technology describe a wireless multimodal sensor system for measuring the electrical conductivity and temperature of the stomach of a dairy cow.

Gallium nitride ultraviolet detector with integrated silicon amplifier:
------------------------------------------------------------------------------------
http://www.tut.ac.jp/english/newsletter/research_highlights/research03.html
Gallium nitride (GaN) and related materials are extensively used for the fabrication of blue LEDs and lasers. However, current GaN based UV detectors necessitate connection of external transistor circuits to amplify the otherwise weak signal from the UV detector.
Here Chang Yong Lee and colleagues at Toyohashi University of Technology describe the realization of GaN Schottky diode UV detectors with integrated silicon-charge transfer type signal processors, thereby eliminating the requirement to-date for attaching external transistor circuits to amplify the weak signal from the GaN UV detector.
