Linear filtering of image subbands for low complexity postprocessing of decoded color images
(SPIE-Int Soc Optical Engineering, 2005)
In [1], image adaptive linear minimum mean squared error (LMMSE) filtering was proposed as an enhancement layer color image coding technique that exploited the statistical dependencies among the luminance/chrominance or ...
Constraint-based routing in traffic engineering
(IEEE, 2006)
Traffic engineering (TE) describes a domain-wide perspective for traffic control as opposed to application-specific concerns of QoS. MPLS is today's most powerful architecture for TE. Constraint-based routing refers to the ...
Algorithmic modifications to SPIHT
(IEEE, 2001)
This paper proposes several low complexity algorithmic modifications to the SPIHT (Set Partitioning in Hierarchical Trees) image coding method of [3] The modifications exploit universal traits common to the real world ...
Comparison of evolutionary techniques for Value-at-Risk calculation
(Springer-Verlag Berlin, 2007)
The Value-at-Risk (VaR) approach has been used for measuring and controlling the market risks in financial institutions. Studies show that the t-distribution is more suited to representing the financial asset returns in ...
Estimation of microstretch elastic moduli by the use of vibrational data
(Springer, 2007)
In the present work, a nonlinear wave theory is used for the estimation of the material properties of a "microstretch" medium. For this purpose a thin plate is considered and triplicate Chebyshev polynomial series are used ...
Automatic XML schema matching
(2009)
As the enterprise systems increasingly use the XML technology in their data presentation, the Enterprise Application Integration is gradually becoming the problem of Xml Schema matching. Different organizations overall ...
Mixed-method validation of pedagogical concepts for an intercultural online learning environment: a case study
(Assoc Computing Machinery, 2007)
The rise of social software poses the challenges to the design and evaluation of a pedagogically sound online learning environment (OLE). Our OLE addresses these challenges by the integration of three pedagogical concepts ...
Readiness and mindset for IT offshoring: Insights from banking and insurance organizations
(2009-07-13)
In this research we examine the IT offshore outsourcing (offshoring) practice of a number of leading finance and insurance organizations in the Netherlands. In particular, we investigate the readiness (the state, condition ...
