This chapter describes the application of MDA (model driven architecture) and UML for the modeling and specification of collaborative business processes, with the purpose of enabling enterprises to establish business-to-business collaborations. The proposed MDA approach provides the components and techniques required for the development of collaborative processes from their conceptual modeling to the specifications of these processes and the partners’ interfaces in a B2B standard. As part of this MDA approach, a UML profile is provided that extends the semantics of UML2 to support the analysis and design of collaborative processes. This UML profile is based on the use of interaction protocols to model collaborative processes. The application of this UML profile in a case study is presented. Also, an overview is provided about the automatic generation of B2B specifications from conceptual models of collaborative processes. In particular, the generation of B2B specifications based on ebXML is described.

This paper presents a short-cut procedure for the design of batch distillations which is equivalent to the Fenske−Underwood−Gilliland procedure for continuous distillations. Given a separation task, we propose computing the minimum number of stages and minimum reflux ratio required to perform it by batch distillation. These parameters are quite different from the continuous N min and R min parameters for the same separation task, because of the difference in the form of the material balances (steady state in continuous but integrated differential mass balances in the batch case). We propose that they should be computed as the number of stages and reflux ratio required by hypothetical batch distillation columns that operate at total reflux or have an infinite number of stages, respectively. Then, it is shown that the performance of batch distillations does correlate in Gilliland coordinates constructed with these batch N min and R min. This produces a quite simple, straightforward method to do preliminary design of batch distillations.

The state reformation that took place in the 1990s and the technological explosion have led governments to reframe their way of working so as to be able to offer new and better services for citizens. To achieve this goal, major obstacles must be overcome, such as the problem of semantic heterogeneity that leads to more difficult recovery and integration of information from different government sectors. Although in the private sector solutions to this problem through the building of ontologies have already been set out, the characteristics of government itself have led the direct application of these practices to fail. This paper presents a process for building a domain ontology in the public sector from scratch. In addition, it presents the application of this process for building an ontology for the Budgetary Domain of Santa Fe Province (Argentina).
