      Empirical Bayes approach to block wavelet function estimation 

      Abramovich, F.; Besbeas, P.; Sapatinas, Theofanis (2002)
      Wavelet methods have demonstrated considerable success in function estimation through term-by-term thresholding of the empirical wavelet coefficients. However, it has been shown that grouping the empirical wavelet coefficients ...

      Numerical investigation of the nonlinear heat diffusion equation with high nonlinearity on the boundary 

      Christou, Marios Andreas; Sophocleous, Christodoulos; Christov, Christo I. (2008)
      A nonlinear heat diffusion problem is considered when the thermal conductivity and heat capacity are nonlinear functions of the temperature. At one of the boundaries a highly nonlinear condition is imposed involving both ...

      The singular function boundary integral method for biharmonic problems with crack singularities 

      Elliotis, Miltiades C.; Georgiou, Georgios C.; Xenophontos, Christos A. (2007)
      We use the singular function boundary integral method (SFBIM) to solve two model fracture problems on the plane. In the SFBIM, the solution is approximated by the leading terms of the local asymptotic solution expansion, ...

      Solvable risk-sensitive control problems with output feedback 

      Charalambous, Charalambos D.; Naidu, D. Subbaram; Moore, Kevin L. (IEEE, 1994)
      In this paper a partially observed nonlinear stochastic control with exponential running cost is considered. Explicit solutions for evaluating expectations of exponential functions are found when the control is assumed to ...

      Statistical analysis of multipath fading channels using generalizations of shot noise 

      Charalambous, Charalambos D.; Djouadi, S. M.; Kourtellaris, C. (2008)
      This paper provides a connection between the shot-noise analysis of Rice and the statistical analysis of multipath fading wireless channels when the received signals are a low-pass signal and a bandpass signal. Under certain ...

      Using time and activity in personalization for the mobile user 

      Panayiotou, Christoforos; Andreou, Maria I.; Samaras, George S. (2006)
      Mobile clients present a new and more demanding breed of users. Solutions provided for the desktop users are often found inadequate to support this new breed of users. Personalization is such a solution. The moving user ...
