QoS-driven adaptation of BPEL scenario execution
- in Web Services, 2009. ICWS 2009. IEEE International Conference on
, 2009
"... BPEL/WSBPEL is the predominant approach for com-bining individual web services into integrated business processes, allowing for the specification of their se-quence, control flow and data exchanges. BPEL however does not include mechanisms for considering the invoked services ’ Quality of Service (Q ..."

BPEL scenario execution: QoS-based dynamic adaptation and exception resolution
"... Abstract. BPEL/WSBPEL is the main approach for combining individual web services into integrated business processes. A BPEL / WSBPEL scenario allows for specifying which services will be invoked, their sequence, the control flow and how data will be exchanged between them. BPEL however does not incl ..."

Secret Key Agreement by Public Discussion From Common Information
- IEEE Transactions on Information Theory
, 1993
"... . The problem of generating a shared secret key S by two parties knowing dependent random variables X and Y , respectively, but not sharing a secret key initially, is considered. An enemy who knows the random variable Z, jointly distributed with X and Y according to some probability distribution PX ..."

) are derived for the case where X = [X 1 ; : : : ; XN ], Y = [Y 1 ; : : : ; YN ] and Z = [Z 1 ; : : : ; ZN ] result from N independent executions of a random experiment generating X i ; Y i and Z i , for i = 1; : : : ; N . In particular it is shown that such secret key agreement is possible for a scenario
Feature Location via Information Retrieval based Filtering of a Single Scenario Execution Trace
- in Automated Software Engineering (ASE 2007
, 2007
"... The paper presents a semi-automated technique for feature location in source code. The technique is based on combining information from two different sources: an execution trace, on one hand and the comments and identifiers from the source code, on the other hand. Users execute a single partial scen ..."

The source code is indexed using Latent Semantic Indexing, an Information Retrieval method, which allows users to write queries relevant to the desired feature and rank all the executed
Specifying and executing reactive scenarios with

This language specifically targets the domain of reactive systems, where an execution is a (virtually) infinite sequence of input/output reactions. More precisely, it is dedicated to the description and t ..."

It can also be useful for early simulation of huge systems, where Lutin programs can be used to describe and simulate modules that are not yet fully developed. The programming style mixes relational

Feature location using probabilistic ranking of methods based on execution scenarios and information retrieval

, 2007
"... Abstract—This paper recasts the problem of feature location in source code as a decision-making problem in the presence of uncertainty. The solution to the problem is formulated as a combination of the opinions of different experts. The experts in this work are two existing techniques for feature lo ..."
