      A context query language for pervasive computing environments 

      Reichte, R.; Wagner, M.; Khan, M. U.; Geihs, K.; Valla, M.; Fra, C.; Paspallis, Nearchos; Papadopoulos, George Angelos (2008)
      This paper identifies requirements for querying and accessing context information in mobile and pervasive computing environments. Furthermore it studies existing query languages showing that they satisfy only a subset of ...

      From beads-on-a-string to colloidal aggregation: novel crystallization phenomena in the PEO-SDS system 

      Leontidis, Epameinondas; Kyprianidou-Leodidou, Tasoula; Caseri, Walter; Kyriacou, Kyriacos C. (1999)
      The anionic surfactant sodium dodecyl sulfate (SDS) interacts strongly with poly(ethylene oxide) (PEO) in aqueous solution, forming micellar aggregates attached to the polymer chains above the so-called critical association ...

      Gold colloids from cationic surfactant solutions. 1. Mechanisms that control particle morphology 

      Leontidis, Epameinondas; Kleitou, K.; Kyprianidou-Leodidou, Tasoula; Bekiari, Vlasoula; Lianos, P. (2002)
      The mechanism of formation of gold particles by reduction of AuIII in solutions of alcyltrimethylammonium chloride surfactants was studied in the absence and in the presence of NaCl. AuIII anions interact strongly with ...

      The micropulse framework for adaptive waking windows in sensor networks 

      Zeinalipour-Yazdi, Constantinos D.; Andreou, Panayiotis G.; Chrysanthis, Panos K.; Samaras, George S.; Pitsillides, Andreas (2007)
      In this paper we present MicroPulse, a novel framework for adapting the waking window of a sensing device S based on the data workload incurred by a query Q. Assuming a typical tree-based aggregation scenario, the waking ...

      Multi-compartment unimolecular micelles from (ABC)n multi-arm star triblock terpolymers 

      Stavrouli, N.; Triftaridou, Aggeliki I.; Patrickios, Costas S.; Tsitsilianis, C. (2007)
      Four linear and four star equimolar terpolymers based on non-ionic hydrophilic methoxy hexa(ethylene glycol) methacrylate, ionizable hydrophilic 2-(dimethylamino)ethyl methacrylate and neutral hydrophobic methyl methacrylate ...

      Polyelectrolytic amphiphilic model networks in water: A molecular thermodynamic theory for their microphase separation 

      Vamvakaki, Maria; Patrickios, Costas S. (2002)
      The aqueous aggregation behavior of networks comprising hydrophilic ionic blocks and hydrophobic nonionic blocks was studied by formulating a molecular thermodynamic theory, which considers the Gibbs free energies of the ...

      Protein complexation with acrylic polyampholytes 

      Patrickios, Costas S.; Hertler, Walter R.; Hatton, T. Alan (1994)
      The interaction of dilute mixtures of proteins and ABC triblock methacrylic polyampholytes at different values of pH was investigated turbidimetrically. The onset of interaction was manifested by large changes in turbidity ...

      Thixotropic rheology of semisolid metal suspensions 

      Burgos, G. R.; Alexandrou, Andreas N.; Entov, V. (2001)
      Understanding the time-dependent flow behavior of semisolid materials (SSM) is essential for the simulation of semisolid processes. During processing, the structure of the material changes with the processing history due ...

      Trade and industrial location with heterogeneous labor 

      Amiti, Mary; Pissarides, Christopher A. (2005)
      It is shown in the context of a new economic geography model that when labor is heterogeneous trade liberalization may lead to industrial agglomeration and inter-regional trade. Labor heterogeneity gives local monopsony ...
