The Virtual Secretary (ViSe) is a kind of intelligent agent that could assist its user in major secretarial work. Users give the orders of what to do, while agents figure out how to do and carry out the tasks. This paper presents the ViSe agents in two aspects: (1) construct individual agent on three intelligence levels: knowledge-base level, learning level and cooperation level; and (2) to mod...

Mathematicians routinely lift operators to structures. For instance, almost every textbook on calculus lifts addition pointwise to functions: ( f + g)(x) = f (x)+ g(x). In this particular example, the lifted operator inherits the properties of the base-level operator. Does this hold in general? In order to approach this problem, one has to make the concept of lifting precise. I argue that lifti...

Spending costs in construction of road pavements has turned this subject into one of the significant points in transportation infrastructure of countries. Concrete slabs consider as a paving method with ability of reducing the rehabilitation needs. Therefore, to manage costs and optimize the thickness of concrete pavements, recognizing the amount of determinative factors’ influence will be requ...

DNA base composition is a fundamental genome feature. However, the evolutionary pattern of base composition and its potential causes have not been well understood. Here, we report findings from comparative analysis of base composition at the whole-genome level across 2210 species, the polymorphic-site level across eight population comparison sets, and the mutation-site level in 12 mutation-trac...

This paper proposes a meta-learning framework in the context of information extraction from the Web. The proposed framework relies on learning a meta-level classifier, based on the output of base-level information extraction systems. Such systems are typically trained to recognize relevant information within documents, i.e., streams of lexical units, which differs significantly from the task of...

The aim of clustering ensemble is to combine multiple base partitions into a robust, stable and accurate partition. One of the key problems of clustering ensemble is how to exploit the cluster structure information in each base partition. Evidence accumulation is an effective framework which can convert the base partitions into a co-association matrix. This matrix describes the frequency of a p...

Interaction between a structure under base excitation and heavy non-structural elements that it supports is significant in the seismic analysis and design of the structure. Heavy non-structural elements may slide/rock under base excitation, and this dynamic action affects the seismic behavior of the supporting structure. Hence, in this study, a numerical model was presented to describe the seis...
