First-principles investigation of LaGaO3 and LaInO3 lanthanum perovskite oxides
(Taylor & Francis Ltd, 2016)Among the class of ABO(3)-type perovskite oxides, LaMO3 (M=Ga and In) compounds are investigated in cubic (Pm-3m), tetragonal (P4mm), hexagonal (P-3m1), rhombohedral (R-3c) and orthorhombic (Pbnm) phases using generalised ... -
Forming a cloud computing based lifelong learning platform: integration of basic computer courses as mass open online courses to university
(Iclel Conferences, 2016)Today's formal educational institutions remain incapable of keeping people's knowledge up to date. Updating information in fields like general culture, information technology, language education and vocational education ... -
Latent Semantic Analysis via Truncated ULV Decomposition
(Ieee, 2016)Latent semantic analysis (LSA) usually uses the singular value decomposition (SVD) of the term-document matrix for discovering the latent relationships within the document collection. With the SVD, by disregarding the ... -
Design and Implementation of a Basic Microcomputer for Educational Purpose
(Ieee, 2016)Today, most of electronic equipments includes at least one microcomputer. Microcomputers control the operation of electronic devices and to provide the required operations. The microcomputer has a constantly developing and ... -
