  2. 1. MULTIFOCAL SPHERICAL FISH LENSES

    Author : Yakir Gagnon; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multifocal Lens; Adaptation; Dispersion; Spherical lens; Model; Fish; Ray-trace; Longitudinal Chromatic Aberration; Longitudinal Spherical Aberration; Modulation Transfer Function; Point Spread Function; Refractive Index Gradient;

    Abstract : Vision is an important source of information for many animals. The lens plays a central role in the visual pathway and hence the ecology of these animals. Fish have spherically shaped crystalline lenses that contain a gradient of refractive index. Like all refracting elements, lens performance depends on the wavelength of the refracted light.

  4. 2. Spherical Crystallization of Benzoic Acid

    Author : Jyothi Thati; Åke Rasmuson; Luis Moreno; Eva Blomberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spherical agglomeration; Spherical agglomeration; Benzoic acid; Solubility phase diagram; Physico mechanical properties; Chemical engineering; Kemiteknik;

    Abstract : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water. READ MORE

  5. 3. Binaural Rendering of Spherical Microphone Array Signals

    Author : Hannes Helmholz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive noise; real-time signal processing; binaural rendering; Spherical microphone arrays;

    Abstract : The presentation of extended reality for consumer and professional applications requires major advancements in the capture and reproduction of its auditory component to provide a plausible listening experience. A spatial representation of the acoustic environment needs to be considered to allow for movement within or an interaction with the augmented or virtual reality. READ MORE

  6. 4. Charged Polymers at Spherical Surfaces

    Author : Anna Akinchina; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; Monte Carlo simulation; diblock polyampholyte brushes; polymer brushes; persistent length; stiffness; complexation; macroion; polyelectrolyte; polyion;

    Abstract : Two separate topics in the area of colloidal chemistry have been investigated by the use of molecular modeling: the structural properties of polyion?macroion complexes and of diblock polyampholyte brushes. The main results were obtained by the use of Monte Carlo simulation in the framework of the primitive model, and in the case of polyampholyte brushes the simulation results were also complemented by lattice mean-field calculations.
