Taking excerpts text can be problematic, as key pieces may not explicit local window. We isolate define problem decontextualization: taking together with its rewriting it to interpretable out context, while preserving meaning. describe an annotation procedure, collect data on Wikipedia corpus, train models automatically decontextualize sentences. present preliminary studies show value decontextualization user-facing task, preprocessing systems perform document understanding. argue is important subtask many downstream applications, definitions resources provided benefit tasks operate sentences occur richer

Vertically Integrated Systems in Stand - Alone

This involves having production units distribute to the consuming units through a single vertical and central distribution network. Each fl oor is served by an indirect connected substation (Figure 3). Enhancing comfort1 and reducing energy demand2 is possible when fl oorto-fl oor (rather than building-to-building) consumption is moderate (cooling) or low (heating) temperature radiant-based sur...

Unbalance Compensation in Stand-alone Microgrids

− The study presented in this paper aims to develop a new method for active and reactive power balancing in a four-wire stand-alone microgrid (MG), which feds single phase loads. Two unbalance compensation controllers are used, for active and reactive powers. The compensation is based on a dump load (DL) and a static compensator (STATCOM), which ensure the balance of the active and reactive pow...
