Isogeometric based formulations for the bending analysis of laminated composite structural elements
Isogeometric analysis (IGA) is a family of numerical methods to solve boundary value problems. The founding principle of isogeometric methods is aimed at integrating computer aided design (CAD) with nite element method ... -
Studies on the behaviour of the fibre reinforced cement stabilised rammed earth
Cement stabilised rammed earth (CSRE) is a monolithic construction used for the loadbearing walls in the buildings and other structures. The soil, fine aggregates and cement form the basic materials for the CSRE construction. ... -
Investigation of Buffer Design and Carbon doping in AlGaN/GaN HEMTs for High Breakdown Voltages
III-nitride HEMTs are strong contenders for next-generation power electronic applications. The superior material and electrical properties render GaN-based transistors suitable for high-power switching. The material ... -
Functional Characterization of a SAND–Domain–containing Factor OsULTRAPETALA1 – a Direct Downstream Target of OsMADS1
Studies on meristem identity regulators in Rice (Oryza sativa), a model plant for cereal crops have revealed how meristem identity and transitions are controlled, bearing implications for crop yield improvement. We were ... -
Nanopore Based Single-molecule Sensors
In the past two decades nanopores have been used as highly sensitive detection systems for exploring the properties of analytes at single molecule resolution. The small dimensions of a nanopore permit the molecule of ... -
