Two-Phase Flow and Heat Transfer across Horizontal Tube Bundles – A Review

This paper presents a state-of-the-art review of two-phase flow and flow boiling across horizontal tube bundles. The review covers studies related to the dynamic aspects of two-phase flow on the shell side of staggered and in-line tube bundles for upward, ...

Active Vision and Receptive Field Development in Evolutionary Robots

Dario Floreano, Claudio Mattiussi, Mototaka Suzuki

In this paper, we describe the artificial evolution of adaptive neural controllers for an outdoor mobile robot equipped with a mobile camera. The robot can dynamically select the gazing direction by moving the body and/or the camera. The neural control sys ...

Vision-based Navigation from Wheels to Wings

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

We describe an incremental approach towards the development of autonomous indoor flyers that use only vision to navigate in textured environments. In order to cope with the severe weight and energy constraints of such systems, we use spiking neural control ...

Hybrid, metric - topological, mobile robot navigation

Nicola Tomatis

This thesis presents a recent research on the problem of environmental modeling for both localization and map building for wheel-based, differential driven, fully autonomous and self-contained mobile robots. The robots behave in an indoor office environmen ...

Method for producing visually evenly spaced typographic characters

Roger Hersch

Methods are proposed for visually evenly spacing of two successive characters taking into account outline shape modifications induced by character grid-fitting. Visually even spacing of characters is obtained by converting the geometric space between two c ...

Evaporation of Ammonia in a Smooth Horizontal Tube : Heat Transfer Measurements and Predictions

John Richard Thome, Daniel Favrat, Olivier Zürcher

Experimental test results for flow boiling of pure ammonia inside horizontal tubes were obtained for a plain stainless steel tube. Tests were run at a nominal saturation temperature of 4°C, nine mass velocities from 20- 140 kg/m2s, vapor qualities from 1-9 ...

Making the future safe for the past: Adding Genericity to the Java Programming Language

Martin Odersky

We present GJ, a design that extends the Java programming language with generic types and methods. These are both explained and implemented by translation into the unextended language. The translation closely mimics the way generics are emulated by program ...

Evaporation du réfrigérant HFC 407C sur des tubes lisses ou à surface améliorée.

John Richard Thome, Daniel Favrat, Olivier Zürcher

The substitution of CFC refrigerants in refrigeration systems, heat pumps and organic Rankine cycles for heat recovery, requires good methods for predicting heat transfer of substitute fluids. The measurements in the LENI test facility (concentric tubes wi ...
