Composite reliability evaluation combining adequacy and security aspects

Currently, it is an ordinary procedure to restrict the use of renewables, mainly wind power, to accommodate a more stable set of generating units (e.g.: thermal units) to supply the load. The purpose of this paper is to discuss particular aspects from the adequacy and security evaluation of generation and transmission (G&T) system that must be revised due to the massive integration of wind power in the present ...

Benchmarking Analysis of Social Media Strategies in the Higher Education Sector

The adoption of social media networks by organizations has been increasing, mainly by using more social networks but also by constantly increasing on the number of messages and received comments posted on these channels. Interestingly, this process apparently has not been accompanied by a carefully planned and strategically design process to provide the essential alignment with organizational goals. This study ...

Preparing relational algebra for "just good enough" hardware

Device miniaturization is pointing towards tolerating imperfect hardware provided it is "good enough". Software design theories will have to face the impact of such a trend sooner or later. A school of thought in software design is relational: it expresses specifications as relations and derives programs from specifications using relational algebra. This paper proposes that linear algebra be adopted as an evolu...
