Characterization of microcapsules

Jutta Christine Wandrey, David Hunkeler

A review on the methods of characterization of multicomponent microcapsules. Requirements to measure the ingress and egress of small and macromols. through the membrane are discussed, along with the relevant theory. The relevant factors to consider in micr ...

Objects + Views = Components?

Martin Odersky

In support of flexible composition, components need to be adaptable and they need to have first-class plugs. Abstract state machines and object-oriented programming each satisfy one of these requirements very well but satisfy the other only incompletely. T ...

Requirements for an architecture for believable social agents

Daniel Thalmann, Anthony Guye-Vuillème

This paper introduces four sociological concepts which we argue are important for the creation of autonomous social agents capable of behaving and interacting realistically with each other as virtual humans. A list of functional requirements based on these ...

Poloidal polarimeter system for current density measurements in ITER

The polarimeter system for ITER features 10 viewing chords covering almost the full poloidal cross section of the plasma in a fan-like arrangement. The 10 laser beams all enter the plasma via 150 mm diam penetrations through the diagnostic plug at the low- ...

Demonstration of microwave generation by a ferroelectric-cathode tube

Catherine Pralong

A ferroelectric cathode is employed in a cyclotron-resonance maser (CRM). The CRM oscillator device operates at similar to 7 GHz, near the cutoff frequency of a hollow cylindrical cavity. The cathode is made of a PLZT 12/65/35 ceramic with high-dielectric ...

An interface for the interactive design of artistic screens

Roger Hersch

The article presents the concepts and the tools involved in the interactive design of artistic screens. The screen elements are derived from a small set of analytical contours provided by the screen designer. We present the requirements that these contours ...

Feasibility Study of the Eu Home Team on a 170ghz 1mw Cw Gyrotron for Ech on Iter

Minh Quang Tran, Trach-Minh Tran

The gyrotron system for ECH and burn control on ITER requires at least 50MW of RF power at frequencies near 170GHz operating in CW. To meet these requirements, high efficiency gyrotron tubes with greater than or equal to 1MW power output capability are nec ...

Startup Methods for Single-Mode Gyrotron Operation

Stefano Alberti, Minh Quang Tran, Trach-Minh Tran

Experimental start-up results of a 118 GHz TE(22,6) gyrotron are presented and compared with theory. The theoretical excitation regimes of competing modes are computed in the energy-velocity-pitch-angle plane. The start-up paths through the plane are deter ...

Exploring user requirements of expert systems in power system operation and control

The most critical viewpoints and requirements of potential users are discussed, and a practical and descriptive definition of what an expert system does (rather than what it is) is proposed. The costs and benefits of its adoption are assessed, and lessons ...

Nitrobenzene production with simultaneous azeotropic distillation

Albert Renken

A process for nitration of C6H6 [71-43-2] with continuous removal of H2O formed in the process (by azeotropic distn. with C6H6) using the reaction heat was described in which the H2SO4 catalyst thus remained undild. and did not need to be regenerated. Requ ...
