Lessons Learnt from the Ultra-Micro Gas
نویسنده
چکیده
The outcome of NEDO supported international research project led by University of Tokyo is reviewed, with respect to developing key technologies for ultra-micro gas turbines (UMGT). The study suggested ‘Finger-top’ gas turbines as a currently feasible extreme that install rotors of 8 mm in diameter with 1.2 million rpm to produce tens of watts net output. Prior to practicing such UMGT system integration, ‘Palm-top’ gas turbine engine of an expected 2 – 3 kW output was first prototyped to operate successfully under a measurable control system, using propane as the fuel and installing a compact heat exchanger, which yielded valuable conceptual as well as practical data base for further advancement of UMGT designing.

Lessons learnt from errors in radiotherapy centers
Background: The purpose of this work is to discover and analyze errors and incidents in some radiotherapy centers, and to introduce methods that could reduce their occurrences, especially those which had happened due to the use of improper and inadequate equipment. This work is a first step toward clarifying the role of education in a risk-conscious culture, and changing the attitude of radioth...

Separation of Ultra - Fine Sulphur Particles from Nta Dispersion by Aphron Flotation
Oxidative scrubbing is used to remove H2S from gas streams. A key problem in regeneration of the absorbent is the removal of fine particles of sulphur from the suspension of the scrubbing liquid. Dispersions of ultra-fine bubbles have been called "colloidal gas aphrons" or aphrons for short. These dispersions have interesting properties and it was found that they have particular advantages in t...
متن کاملAgent-based Ubiquitous Systems: 9 Lessons Learnt
The recent emergence of agent prototyping environments for developing Java agents (Aglets, JATlite, JACK, Agent Factory) and the availability of the J2ME (Java 2Micro Edition) on light devices (PDAs and cellular phones) provides the ability for strong agenthood to be delivered in the mobile and ubiquitous sector. This is an experience paper that discusses the lessons learnt in the construction ...
