Keyword extraction attracts much attention for its significant role in various natural language processing tasks. While some existing methods for keyword extraction have considered using single type of semantic relatedness between words or inherent attributes of words, almost all of them ignore two important issues: 1) how to fuse multiple types of semantic relations between words into a unifor...

In recent years, many private corporations and government organizations have digitized corpuses of legacy paper documents. Often, these organizations hope to take advantage of digital representations to transform costly manual tasks associated with paper archives into less-costly computer-assisted tasks. The most common approach toward automated information extraction is through inverted indexi...

This contribution gives an introduction to an integrated vehicle routing and resource allocation problem. We refer to it as the Swap Trailer Problem and formulate the mathematical model. After the analysis of dynamic decision problems and the development of a framework for this problem, we highlight the dynamic aspect of the problem. Two different solution strategies are supposed. Special prope...

The gaining popularity of production rule systems had as a result the recent Rule Interchange Format (RIF) extensibility framework. This framework, developed by the W3C Consortium, is for modeling production rules in forward chaining rule engines. Our research, based on this RIF extensibility framework, sets the foundational work for a flexible new rule language to facilitate knowledge represen...

While the use of tangible interfaces in music is mostly restricted to exploration and manipulation of pre-composed music due to their limited amount of degrees of freedom, no system has yet been developed that allows explicit music composition through tangible interaction. SoundStrand is a tangible interface that supports an alternative paradigm to the process of music composition. This approac...

The problem of robust nonlinear energy-to-peak filtering for nonlinear descriptor systems with model uncertainties is addressed. The system is assumed to have nonlinearities both in the state and output equations as well as norm-bounded time-varying uncertainties in the realization matrices. A generalized nonlinear dynamic filtering structure is proposed for such a class of systems with more de...

This work is focused on impedance control of robot manipulators performing six-degree-of-freedom interaction tasks. An energy-based formulation leads to formally deriving the dynamic equation characterizing a mechanical impedance at the end effector. An inverse dynamics strategy with contact force and moment measurement is adopted to obtain a configurationindependent desired impedance. For give...

In this paper, a precoding scheme for interference mitigation based only on local channel state information is proposed for downlink multicell multiantenna systems with joint transmission. The investigated scheme places interference components at the receivers coming from the different transmitters in predefined subspaces, so that they are completely or approximately cancelled. It is shown how ...

The banking sector is one of the important financial intermediaries in an economic system. Improvement in the banking sector can achieve optimal allocation of financial resources. The performance of banks and other financial service providers has direct effect on economic growth. One of the factors that can affect the banks operation is economic freedom. Economic freedom and freedom of private ...
