A parametric experimental study was carried out to the influence of temperature (25-40°C), concentration (0.15-6 wt. % methanol in water) and rate flow (1.12-8.65 g/s) on performance a single mini-direct fuel cell (DMFC) operating semi passive mode with cathode active anode. Open circuit voltage, maximum power density efficiency were analyzed. To this purpose, open voltage current-voltage curves measured different conditions. Results indicate that is most decisive parameter increase DMFC...
Este artigo examina a disparidade entre formação pedagógica de professores universitários e eficácia na comunicação suas pesquisas. Utilizando uma metodologia qualitativa, pesquisa inclui revisão literatura abrangente sobre evolução da no ensino superior, além analisar materiais didáticos práticas pedagógicas em diferentes instituições. A estrutura do estudo é dividida capítulos que abordam, inicialmente, história os conceitos fundamentais pedagogia universitária. Segue com análise crítica...
Direct methanol fuel cells (DMFCs) typically operate in passive mode, where is distributed across the membrane electrode assembly through natural diffusion. Usual concentrations range from 1% to 5% by weight (wt.%), although this can vary depending on specific configuration and application. In work, effect of an additional pumping system supply has been analyzed varying flow rate within pump’s range. To end, a parametric experimental study was carried out influence temperature (25–40 °C),...
A unit disk graph is the intersection of a family disks in plane. If do not overlap, it also coin or penny graph. It known that finding maximum independent set NP-hard problem. In this work we extend result to graphs. Furthermore, prove minimum clique partition NP-hard, and present two linear-time approximation algorithms for computation partitions: 3-approximation algorithm graphs 2-approximation
A fullerene graph is a cubic bridgeless plane with all faces of size $5$ and $6$. We show that every on $n$ vertices can be made bipartite by deleting at most $\sqrt{12n/5}$ edges has an independent set least $n/2-\sqrt{3n/5}$ vertices. Both bounds are sharp, we characterize the extremal graphs. This proves conjectures Došlić Vukičević Daugherty. deduce two further independence number graphs, as well new upper bound smallest eigenvalue graph.
