(John Wiley & Sons, 2014)Defining and formalizing the software development process is a common means for improving it. Software processmodeling is often a challenging and expensive endeavor, because a well specified processmay still include in ...
-
(MDPI AG, 2019)Avocado oil has generated growing interest among consumers due to its nutritional and technological characteristics, which is evidenced by an increase in the number of scientific articles that have been published on it. ...

(American Physical Society, 2017)Because of their quantum fluctuations, axion fields had a chance to experience field excursions traversing many minima of their potentials during inflation. We study this situation by analyzing the dynamics of an axion ...
-
(Elsevier, 2012-10-22)Incremental equilibrium equations and corresponding boundary conditions for an isotropic, hyperelastic and incompressible material are summarized and then specialized to a form suitable for the analysis of a spherical shell ...

Aysen seismic swarm (January 2007) in southern Chile: analysis using Joint Hypocenter Determination (SPRINGER, 2010-10)A seismic swarm at the Aysén fjord started in January, 2007, reaching its highest activity between January and April, 2007. It was punctuated by the Mw5.3 23rd January event and the Mw6.2 21st April event which triggered ...

(Universidad de Chile, 2018)El presente trabajo muestra la implementación de técnicas de clasificación basadas en árboles de decisión para resolver y entender el problema de identificación de genes anotados en el ADN de la bacteria Escherichia Coli. ...
-
(Universidad de Chile, 2022)El presente trabajo define un modelo de subgrafos aleatorios de torneos $T_{p}$ y desarrolla técnicas que combinan ideas de grafos aleatorios, de torneos y de teoría extremal para encontrar ciertas familias de subestructuras ...
-
(Amer Physical Soc, 2015)It was recently shown that a large value of the tensor to scalar ratio r implies a constraint on the minimum value of the sound speed c(s) of primordial curvature perturbations during inflation that is stronger than current ...
-
(Springer, 2015)A b-coloring of a graph is a proper coloring such that every color class contains a vertex that is adjacent to all other color classes. The b-chromatic number of a graph , denoted by , is the maximum number such that admits ...

(Elsevier B.V., 2019)Backyard production systems (BPS) that involve poultry are a good way to improve food security and poverty alleviation. Few studies have been carried out to quantify the contribution of poultry production to these households ...
-
(Royal Society of Chemistry, 2020)We confine a dense suspension of motileEscherichia coliinside a spherical droplet in a water-in-oil emulsion, creating a "bacterially" propelled droplet. We show that droplets move in a persistent random walk, with a ...
