Abstract We have studied the Steiner tree problem using six-pin soap films in detail. We extend the existing method of experimental realisation of Steiner trees in n-terminal problem through soap films to observe new non-minimal Steiner trees. We also produced spanning tree configurations for the first time by our method. Experimentally, by varying the pin diameter, we have achieved these new s...

Abstract The thermal resistance of semiconductor thin films is predicted using lattice dynamics (LD) calculations and molecular dynamics (MD) simulations. We consider Si and Ge films with thicknesses, LF , between 0.2 nm and 30 nm that are confined between larger extents of the other species (i.e., Ge/Si/Ge and Si/Ge/Si structures). The LD predictions are made in the classical limit for compari...

ISSN 2250 – 1088 | © 2011 Bonfring Abstract--This paper presents a high-Q MWCNT (Multi Wall Carbon Nano-Tube) network based pulse-shaped on-chip embedded nano-inductor for power electronic circuits. This high-Q inductor is fabricated using a composite of MWCNT (multi Wall Carbon Nano Tube) network and Fe in semiconductor processing environment. A layer of nano composite film (Cu/CoFe2o4) is pat...

Abstract. We give a model for the deformation and magnetization of a single crystal ferromagnetic shape memory thin film under the influence of an applied magnetic field. The energy is nonconvex since it models multiple phases and symmetry-related variants of the crystal structure. Nonconvexity is also presented by the magnetic saturation condition which requires the magnetization to have a con...

ABSTRACT Background: The radiographic image accuracy depends on the X-ray film information visibility. Good visibility is found by good contrast. Radiation exposure parameters (kVp, mAs) and film processing conditions have impact on contrast. In dentistry radiography machines, exposure time and processing procedure are set by radiographer. No optimized exposure time and process...

the renowned majority of legal theoreticians (uṣūliyyūn) believe that the premises of ḥikmat are three: 1. the possibility of absoluteness and limitation (iṭlāq wa taqyīd); 2. non-provision of evidence (qarīna); and 3. the speaker being in an expressive position. muḥaqqiq khurāsānī, however, has added a fourth premise, i.e., lack of agreed certitude in conversing face to face (takhātub). some l...

Patients & Methods: Direct film was prepared and samples were cultured aerobically and anaerobically from the deeper parts of the suppurative exudate of secondarily infected skin of 37 outpatients and 23 inpatients suffering from various dermatoses. This was followed by antibiotic sensitivity testing in addition to testing of gram positive and gram negative organisms for beta lactamase and exte...

The formation of spatiotemporal patterning in biology has intrigued experimentalists and theoreticians for many generations. Here we present a brief review of some mathematical models for pattern formation and then focus on three models which use the phenomenon of chemotaxis to generate pattern.

An international workshop on animal migration was held at the Lorentz Center in Leiden, The Netherlands, 2-6 March 2009, bringing together leading theoreticians and empiricists from the major migratory taxa, aiming at the identification of cutting-edge questions in migration research that cross taxonomic borders.
