Aspect-Oriented Programming (AOP) has arisen as a new technology to support a better SoC (Separation of Concerns), intending to contribute to the development of reusable, maintainable, and evolvable software systems. Aspects have been also explored in the early life cycle phases, aiming at contributing to a more adequate development of aspect-oriented software systems. In this perspective, in o...

A short and self-contained presentation of the results known about the Pom-peiu problem is given and a new result is obtained. In particular, it is proved that if D 1 has Pompeiu's property (P-property) then D 2 has it, provided D 2 is sufficiently close to D 1 in the following sense: meas(D 12 \ D 12) is sufficiently small. Here D 12 := D 1 ∪ D 2 , D 12 := D 1 ∩ D 2 .

In this paper we offer an overview on the topic of Microservices Science and Engineering (MSE) and we provide a collection of bibliographic references and links relevant to understand an emerging field. We try to clarify some misunderstandings related to microservices and Service-Oriented Architectures, and we also describe projects and applications our team have been working on in the recent p...

Data integration is the process by which data from heterogeneous data sources are conceptually integrated into a single cohesive data set. In recent years agents have been increasingly used in information systems to promote performance. In this work we propose a modeling framework for agent oriented data integration to demonstrate how agents can support this process. We provide a systematic ana...

This paper deals with the design of crosscutting features in general and in the UML in particular. We postulate a couple of issues that we think an aspect-oriented designer is faced with when designing crosscutting features. These issues include the independent specification of the crosscutting details and of where to crosscut, the designation of crosscut or referenced elements, the characteriz...

The GeoWebAgri-project evaluates the use of spatial data in precision farming tasks. A service-oriented spatial data infrastructure working with standards could identified as optimal environment for the users’ needs. Using standards of OGC, ISO and W3C help to increase the functionality, usability and accessibility of spatial based applications in agriculture.

Dynamic changes of services and requirements require service connection relationships adaptable in service compositions. This paper presents an adaptable service connector model and related language and tools. The model presents service connection relationships as an explicit component with which service connections can be reconfigured and changes of services involved in the interaction can be ...

COSMA proposes a novel SLA management approach for composite services. It supports a composite service provider in managing SLAs with providers of atomic services, in managing SLAs with requesters of composite services, and aligning both SLA management activities with each other. On this basis, a composite service provider can control and optimize its composite SLA management activities during ...
