The role of women in politics almost all countries experiences obstacles, especially developing countries, with both structural and cultural constraints. constraints referred to are the level education, economy, work housewives, child care, kitchen work. This is identified as a second-class job that difficult balance men when it comes involvement public sector. While factors place private space...

Frequency control rebalances supply and demand while maintaining the network state within operational margins. It is implemented using fast ramping reserves that are expensive and non-renewable, and which are expected to grow with the increasing penetration of renewables. The most promising solution to this problem is the use of demand response, i.e. load participation in frequency control. Yet...

In this paper, we consider economies with (possibly endogenous)solvency constraints under uncertainty. Long-run inefficiency corresponds toa feasible redistribution yielding a welfare improvement beginning from everycontingency reached by the economy. A sort of Cass Criterion (Cass [11]) com-pletely characterizes long-run inefficiency. This criterion involves only observ-abl...

Existing systems that support semistructured views do not maintain semantics during the process of designing views. Thus, there is no guarantee that the views obtained are valid and reversible views. In this paper, we propose an approach to designing valid and reversible semistructured views. We employ four types of view operators, namely, select, drop, join and swap operators, and develop a se...

Existing systems that support semistructured views do not maintain semantics during the process of designing the views. Thus, these systems do not guarantee the validity and reversibility of the views. In this paper, we propose an approach to address the issue of valid and reversible semistructured views. We design a set of view operators for designing semistructured views. These operators are ...

In this paper we study a DL rich enough to express UML class diagrams including ISA and disjointness between classes (but not covering constraints), typing of associations, and participation and functional cardinality constraints. For such a DL, which we call DL-Lite, we propose novel reasoning techniques for a variety of tasks, notably including query containment and query answering for conjun...

In e-commerce, customers have become Information System users. In this environment of nonmandatory usage, remote, untrained users need to quickly feel comfortable and satisfied with a site encounter. Throughout the literature for four decades, a commonly cited factor pertaining to system success has been user participation in the systems development process. Among other things this is likely to...
