Reliability of a concept inventory to determine the level of students in statics
(Institute of Electrical and Electronics Engineers Inc., 2019-01-01)
Basic core courses in engineering are often taught and assessed only through procedural approaches, neglecting the conceptual grounds of the subject. In an effort to change that, a Concept Inventory test was applied to 195 ...

A laboratory scale device for microencapsulation of genetically engineered cells into alginate beads
(Pontificia Universidad Católica de Valparaíso, 2002-12)
The microencapsulation of recombinant cells, widely used for in vitro high-density cell culture, is a novel and potentially cost-effective method of in vivo heterologous protein delivery, where the protein producing cells ...
Reliability-Aware Design Space Exploration for Fully Integrated RF CMOS PA
(Institute of Electrical and Electronics Engineers, 2020-03)
A design for reliability approach is proposed for fully integrated RF CMOS class A-to-C power amplifiers. Reliability hazards like time dependent dielectric breakdown and hot carrier injection are mapped into the design ...
