Density of impurity states of hydrogenic impurities in an inverse parabolic quantum well under the magnetic field
(ELSEVIER SCIENCE BV, 2007)
We investigated the effects of the magnetic field on the density of impurity states in a GaAs/GaAlAs inverse parabolic quantum well (lPQW) for different Al concentrations at the well center. The calculations were performed ...
Multicriteria choice of ore transport system for an underground mine: application of PROMETHEE methods
(SOUTH AFRICAN INST MINING METALLURGY, 2004)
The aim of this paper is to demonstrate the implementation of multicriteria analysis in selection of the most suitable underground ore transport system for a chromite mine in Turkey. The related problem includes five ...
THERMAL-DEGRADATION OF BLENDS OF PVC WITH POLYDIMETHYLSILOXANE
(ELSEVIER SCI LTD, 1993)
The thermal degradation of blends of PVC with polydimethylsiloxane (PDMS) has been studied by thermogravimetry (TG) over the whole composition range and by thermal volatilisation analysis (TVA) for 1:1 by weight blends. ...
New records and a checklist of Cephidae (Hymenoptera: Insecta) of Turkey with a short biogeographical consideration
(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2010)
Twenty-five species of Cephidae are reported from Turkey based on literature records and specimens collected mainly from Central Anatolia. Of these Cephus fumipennis Eversmann, C. nigrinus Thomson, C. pulcher Tischbein, ...
Layered feedforward neural network is relevant to empirical physical formula construction: A theoretical analysis and some simulation results
(ELSEVIER SCIENCE BV, 2005)
We theoretically establish that, contrary to superficial observation, constructing an empirical physical formula (or physical law interchangeably) to explain the physical phenomenon is inherently full with several serious ...
Interruption time effects on InGaAs/InAlAs superlattices of quantum cascade laser structures grown by MOCVD
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2016)
We report the growth of high quality InGaAs/InAlAs quantum cascade laser (QCL) structure which composed of superlattices (SLs) and the effects of interruption time between each layer of the SL structure. Inserting an ...

Electric and magnetic field modulated energy dispersion, conductivity and optical response in double quantum wire with spin-orbit interactions
(ELSEVIER SCIENCE BV, 2018)
We study the influence of electric field on the electronic energy band structure, zero-temperature ballistic conductivity and optical properties of double quantum wire. System described by double well anharmonic confinement ...
