Towards an analytical framework of science communication models [PDF]
, 2008 This chapter reviews the discussion in science communication circles of models for public communication of science and technology (PCST). It questions the claim that there has been a large-scale shift from a ‘deficit model’ of communication to a ...

MODELLING AND EVALUATION OF OPERATIONAL COMPETITIVENESS OF MANUFACTURING ENTERPRISES [PDF]
Kvalita Inovácia Prosperita, 2009 This paper is aiming to connect previous research in global competitiveness analysis. Research is based on doing numerous case studies and creating analytical models to evaluate the overall competitiveness, which is a novel concept by integrating the ...

Analytical models for quark stars
, 2007 We find two new classes of exact solutions to the Einstein-Maxwell system of equations. The matter content satisfies a linear equation of state consistent with quark matter; a particular form of one of the gravitational potentials is specified to ...

Analytical Dynamical Models for Double-Power-Law Galactic Nuclei [PDF]
, 1996 Motivated by the finding that the observed surface brightness profile of many galactic nuclei are well fit by double-power-laws, we explore a range of spherical self-consistent dynamical models with this light profile.

Comparison of the Results of Analytical and Numerical Models of Pre-Reinforcement in Shallow Tunnels
Archives of Civil Engineering, 2017 The steel pipe umbrella is a widely used technology when tunnelling in weak soils in order to create pre-support ahead of the tunnel face. The design of steel pipes is frequently done through simplified analytical approaches which are easy to apply but ...

Fast optimisation procedure for the selection of L-PBF parameters based on utility function
Virtual and Physical Prototyping, 2022 L-PBF is an additive manufacturing process forming parts with complex geometries by adding material layer by layer. The selection of the process parameters in L-PBF has a significant impact on the mechanical properties of the printed parts.

Relativistic and Newtonian core-shell models: analytical and numerical results [PDF]
, 1998 We make a detailed analysis of Newtonian as well as relativistic core-shell models recently proposed to describe a black hole or neutron star surrounded by shells of matter, and in a seminal sense also galaxies, supernovae and star remnants since there ...

ANALYTIC MODELING OF STARSHADES [PDF]
The Astrophysical Journal, 2011 External occulters, otherwise known as starshades, have been proposed as a solution to one of the highest priority yet technically vexing problems facing astrophysics - the direct imaging and characterization of terrestrial planets around other stars. New apodization functions, developed over the past few years, now enable starshades of just a few tens

Analytical Study of Certain Magnetohydrodynamic-alpha Models
, 2006 In this paper we present an analytical study of a subgrid scale turbulence model of the three-dimensional magnetohydrodynamic (MHD) equations, inspired by the Navier-Stokes-alpha (also known as the viscous Camassa-Holm equations or the Lagrangian ...
