It has been suggested that “historians are particularly suited” to exploring teaching about future.

This paper presents an efficient meta-heuristic algorithm for optimization of double-layer scallop domes subjected to earthquake loading. The optimization is performed by a combination of harmony search (HS) and firefly algorithm (FA). This new algorithm is called harmony search firefly algorithm (HSFA). The optimization task is achieved by taking into account geometrical and material nonlinear...

Personal search history is an important type of personal information, from which we can learn a user’s interests and information needs, thus improve the search service for the user. In this paper, we describe our recent work on User-Centered Adaptive Information Retrieval (UCAIR), which aims at capturing personal search history with a client-side search agent and exploiting the history informat...
