Improvement of heat and water management in gas diffusion layers (GDL) is a critical issue to high-performance proton exchange membrane fuel cells (PEMFC). In this study, we develop gas–liquid-solid coupled solver simultaneously model the liquid transport, vapor condensation, conjugate transfer, electric conduction their interactions. A stochastic method employed reconstruct 3D structural GDL. ...

This study aims to look at the effectiveness of Guided Discovery Learning (GDL) learning model and Project-Based (PjBL) in terms achievement, self-confidence, students' critical thinking skills Digital Beauty Design course. type research is Quasi experiment. The subjects this were two classes students from Department Cosmetology Education, Padang State University who randomly selected. Data ana...

Sigil is an e-module creation software that can be used by high school teachers to help provide various teaching materials. However, the teacher's ability use still low where teacher not able apply materials in this e-module. E-modules online learning. One of learning models Guided Discovery Learning (GDL) model. For reason, society service for chemistry who are members Padang Panjang Chemistry...

In this work, the influence of geometric and mechanical properties constitutive layers a Proton Exchange Membrane Fuel Cell (PEMFC) on system performance was investigated. More specifically, study focused internal electrical resistances due to interlayer contacts. Indeed, contact are one main sources ohmic losses in PEMFC therefore require special attention improve efficiency. To end, Design Ex...

Recently the general Game Description Language (GDL) has been extended so as to cover arbitrary games with incomplete/imperfect information. Learning—without human intervention—to play such games poses a reasoning challenge for general game-playing systems that is much more intricate than in case of complete information games. Action formalisms like the Situation Calculus have been developed fo...

Injectable biomaterials to aid bone regeneration are worth investigating in bone tissue engineering due to minimized invasive damages. In this study, a novel in situ formed composite cement consisting of alginate and Sr-containingmesoporous calcium silicate nanoparticles (mSCS) has been designed. Firstly, mSCSwere fabricated with Sr-substitution for Ca in mesoporous calcium silicate nanoparticl...

One of the oldest dreams in the research area of Artificial Intelligence is the design of autonomous robots with problem-solving ability comparable to that of humans. Beginning of the 70's was the Stanford Research Institute Planning System STRIPS (Fikes & Nilsson, 1971). Its formalism for the description of action planning domains is fundamental. STRIPS is motivated by mapping plans to robots,...
