Hybrid Simultaneous Localization and Map Building: Closing the Loop with Multi-Hypotheses Tracking

In this paper simultaneous localization and map building is performed with a hybrid, metric - topological, approach. A global topological map connects local metric maps, allowing a compact environment model, which does not require global metric consistency ...

Development of a Diabatic Two-Phase Flow Pattern Map for Horizontal Flow Boiling

John Richard Thome, Daniel Favrat, Olivier Zürcher

An improved two-phase flow pattern map is proposed for evaporation in horizontal tubes. Based on new flow pattern data for three different refrigerants covering a wide range of mass velocities, vapor qualities and heat fluxes. The new flow pattern map incl ...

Combining Topological and Metric: A Natural Integration for Simultaneous Localization and Map Building

Roland Siegwart, Nicola Tomatis

In this paper the metric and topological paradigm are integrated in a single system for both localization and map building. A global topological map connects local metric maps, allowing a compact environment model, which does not require global metric cons ...

Simultaneous Localization and Map Building: A Global Topological Model with Local Metric Maps

Roland Siegwart, Nicola Tomatis

In this paper an approach combining the metric and topological paradigm for simultaneous localization and map building is presented. The main idea is to connect local metric maps by means of a global topological map. This allows a compact environment model ...

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 ...

Flow Boiling in Horizontal Tubes. Part 1; Development of a Diabatic Two–Phase Flow Pattern Map

John Richard Thome, Daniel Favrat

An improved two-phase flow pattern map is proposed for evaporation in horizontal tubes. The new map was developed based on flow pattern data for five different refrigerants covering a wide range of mass velocities and vapor qualities. The new map is valid ...

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 ...

Prediction of Two-Phase Flow Patterns for Evaporation of Refrigerant R–407C Inside Horizontal Tubes.

John Richard Thome, Daniel Favrat, Olivier Zürcher

Two-phase flow pattern data have been obtained experimentally for R-407C flowing inside 12 mm bore sight glasses, which were located at the outlets of 3 m long, plain bore copper tube heat transfer test sections. The tests covered nominal mass velocities o ...

An integrated map of the genome of the tubercle bacillus, Mycobacterium tuberculosis H37Rv, and comparison with Mycobacterium leprae

Stewart Cole

An integrated map of the genome of the tubercle bacillus, Mycobacterium tuberculosis, was constructed by using a twin-pronged approach. Pulsed-field gel electrophoretic analysis enabled cleavage sites for Asn I and Dra I to be positioned on the 4.4-Mb circ ...

MycDB: an integrated mycobacterial database

Stewart Cole

As part of ongoing efforts to investigate the molecular biology of the human pathogens in the genus Mycobacterium, a customized database was developed specifically for these organisms and implemented in ACEDB database manager software. The data loaded incl ...
