Mobile objects in distributed Oz

Peter Van Roy, Seif Haridi, Per Brand, Gert Smolka, Michael Mehl, Ralf Scheidhauer
1997 ACM Transactions on Programming Languages and Systems  
These ideas have been implemented in Distributed Oz, a concurrent object-oriented language that is state aware and has dataflow synchronization.  ...  In particular, we show how to give objects an arbitrary mobility behavior that is independent of the object's definition.  ...  ACKNOWLEDGEMENTS We thank Luc Onana for fruitful discussions that led to mobile ports and to the proof given in Appendix A.1. We thank Christian Schulte for his help with the shared editor.  ...

Multiparadigm Model Oriented to Development of Grid Systems [chapter]

Jorge Luis Victória Barbosa, Cristiano André da Costa, Adenauer Corrêa Yamin, Cláudio Fernando Resin Geyer
2004 Lecture Notes in Computer Science  
Besides, we propose the Grid Holo (GHolo), a platform to support the multi-domain heterogeneous distributed computing of programs developed in Holo. GHolo is based on object mobility and blackboards.  ...  This distributed model can be fully implemented on Java platform.  ...  In addition, Jinni does not work with logical mobility and with levels of encapsulated blackboards. So, Oz and Jinni have a kind of mobility.  ...

Methods for Determining Mobile Location in Zones without GPS Reception

P.M. Porvatov, S.M. Elsakov
2016 Journal of Computational and Engineering Mathematics  
In reality it is not possible to use only accelerometer, gyroscope and magnetic compass, because it is necessary to calculate an object location from the already known point.  ...  The paper is devoted to methods of determination of mobile device location in zones where GPS signal does not get, using only sensors of the mobile device.  ...  force distributed along axes OX, OY, OZ depending on a tilt angle to each axis, where g = √ g 2 x + g 2 y + g 2 z .

Privacy Engineering in Dynamic Settings

2017 2017 IEEE/ACM 39th International Conference on Software Engineering Companion (ICSE-C)  
Modern distributed software platforms are linking smart objects such as smartphones, cars and health devices to the internet.  ...  A frequent challenge in the design of such platforms is determining the appropriate information disclosure protocol to use when one object interacts with another.  ...  Whereas, the distribution of objects introduces new dynamics that makes these assumptions difficult to hold.  ...

Specifying and Verifying Holonic Multi-Agent Systems Using Stochastic Petri Net and Object-Z: Application to Industrial Maintenance Organizations [chapter]

Belhassen Mazigh, Abdeljalil Abbas-Turki
2012 Petri Nets - Manufacturing and Computer Science  
However, OZ does not support the effective definition of concurrent and distributed systems and OZ specifications often do not have an explicit operational semantics.  ...  SPN expressed in OZ This section discusses aspects of SPN expressed in OZ. These aspects can be obtained by successive refinements starting from formal definition of ordinary PN.  ...

A Virtual Machine for a Process Calculus [chapter]

Luís Lopes, Fernando Silva, Vasco T. Vasconcelos
1999 Lecture Notes in Computer Science  
We present some performance results and compare them to other languages such as Pict, Oz, and JoCaml.  ...  The system runs byte-code files, assembled from an intermediate assembly language representation, which is in turn generated by a compiler.  ...  We are interested in using TyCO to study the issues involved in the design and implementation of languages with run-time support for distribution and code mobility.  ...

High-Level Networking With Mobile Code And First Order AND-Continuations [article]

Paul Tarau, Veronica Dahl
2004 arXiv   pre-print
Mobile threads are implemented by capturing first order continuations in a compact data structure sent over the network.  ...  Among the examples, we describe how to build programmable client and server components (Web servers, in particular) and mobile agents.  ...  The Oz 2.0 distributed programming proposal of (Van makes object mobility more transparent, although the mobile entity is still the state of the objects, not "live" code.  ...

High-level networking with mobile code and first order AND-continuations

PAUL TARAU, VERONICA DAHL

Mobile threads are implemented by capturing first order continuations in a compact data structure sent over the network.  ...  Among the examples, we describe how to build programmable client and server components (Web servers, in particular) and mobile agents.  ...  Although thread mobility is not implemented in Distributed Oz 2, some of this functionality can be emulated in terms of network transparent mobile objects.  ...

A service-oriented language for programming mobile agents

Hervé Paulino, Luís Lopes
2006 Proceedings of the fifth international joint conference on Autonomous agents and multiagent systems - AAMAS '06  
In this paper we present Mob, a service-oriented scripting language for programming mobile agents in distributed systems.  ...  The main feature of the language is the integration of the service-oriented and the mobile agent paradigms.  ...  Agents are handled in Mob programs much like objects are handled in object-oriented languages. The service is another main abstraction.  ...
