Foreword
ETAPS 2005 was the eighth instance of the European Joint Conferences on Theory
and Practice of Software. ETAPS is an annual federated conference that was estab-
lished in 1998 by combining a number of existing and new conferences. This year it
comprisedfiveconferences(CC,ESOP,FASE,FOSSACS,TACAS),17satellitework-
shops (AVIS, BYTECODE, CEES, CLASE, CMSB, COCV, FAC, FESCA, FINCO,
GCW-DSE,GLPL,LDTA,QAPL,SC,SLAP,TGC,UITP),seveninvitedlectures(not
including those that were specific to the satellite events), and several tutorials. We re-
ceivedover550submissionstothefiveconferences thisyear,givingacceptance rates
below 30% for each one. Congratulations to all the authors who made it to the final
program!Ihopethatmostoftheotherauthorsstillfoundawayofparticipatinginthis
excitingeventandIhopeyouwillcontinuesubmitting.
The events that comprise ETAPS address various aspects of the system develop-
ment process, including specification, design, implementation, analysis and improve-
ment. The languages, methodologies and tools which support these activities are all
well within its scope. Different blends of theory and practice are represented, with an
inclination towards theory with a practical motivation on the one hand and soundly
based practice on the other. Many of the issues involved in software design apply to
systems in general, including hardware systems, and the emphasis on software is not
intendedtobeexclusive.

Preface
This volume collects the proceedings of “Foundations of Software Science and Com-
putation Structures,” FOSSACS 2005. FOSSACS is a member conference of ETAPS,
the “European Joint Conferences on Theory and Practice of Software,” dedicated to
foundationalresearchforsoftwarescience.Itinvitessubmissionsontheoriesandmeth-
odstounderpintheanalysis,integration,synthesis,transformation,andverificationof
programsandsoftwaresystems.Topicscoveredusuallyinclude:algebraicmodels;au-
tomata and language theory; behavioral equivalences; categorical models; computa-
tionprocessesoverdiscreteandcontinuousdata;computationstructures;logicsofpro-
grams;modal,spatial,andtemporallogics;modelsofconcurrent,reactive,distributed,
andmobilesystems;modelsofsecurityandtrust;language-basedsecurity;processal-
gebras and calculi; semantics of programming languages; software specification and
refinement;andtypesystemsandtypetheory.
