In applications that need meteorological forecast data, for instance for planning purposes (such as construction or environmental applications), each weather service is currently an effort-intensive result of domain-dependent programming. Instead, such applications need weather information platforms that would combine new forecast technologies and new information and communication technologies in a flexible manner. In this context, we introduced SITUMET, a platform for situation-based meteorological services. The core of the platform is based on (i) open sensor integration, (ii) a flexible forecast module, and (iii) situation-based service generation. In this paper we focus on the later, which is based on the notion of users' context that remains constant during a time interval. We introduce a situation-centric approach to dynamic weather service provision in push and pull mode. It is based on a common model for current and planned activity sequences and for weather information. We illustrate our approach with a particular up-and-running mobile application defined in the SITUMET framework. Copyright 2008 ACM.

The participation of women science,technology,engineering and mathematics(STEM)and energy fields is essential in advancing knowl-edge,securing economic growth,promoting prosperity and contribut-ing to the well-being of *** the number of women in-volved in STEM fields has recently witnessed an increase in compar-ison to their natural counterparts,the“leaky pipeline”metaphor still applies.A greater number of women“leak out”and leave the educa-tional and professional pipelines at every stage of their lives,transition-ing from school to university to their careers,than men[1].The epitome of gender differences in the fields of STEM and energy industry can be captured by the disparities in representation of women in publications,salaries,senior rankings,annual productivity and resources allocation[2].

Kernel/2r is a software infrastructure that provides the integration platform for the construction of distributed process-oriented multi-user/multi-role systems. Kernel/2r includes different process engines that enable the enactment of formally defined process models, thus assisting users in staying in line with procedures and regulations required by law or by the organization or ISO 9000 quality standards, for instance. The authors demonstrate the appropriateness of Kernel/2r as a basis for the construction of application systems in the engineering domain as well as in the commercial domain by discussing the IRIN Software Factory and the OTIS on-line ticket vending system.< >
