Determination of the numerical parameters of a continuous damage model for the structural analysis of clay brick masonry
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2012-12-01)
Models based on the continuous damage theory present good responses in representing the nonlinear behavior of reinforced concrete structures with loss of strength and stiffness of the material. However, damage theory is ...
Profile of Children with Deficits in Numerical Cognition
(Pontifica Univ Javeriana, Fac Psych, 2017-01-01)
This study aimed to characterize the neurocognitive profile of children regarding quantitative, intellectual, and mnemonic skills; and their emotional state. The sample consisted of 42 school children 8-10 years old, divided ...
Rectal Douching Prevalence and Practices Among Peruvian Men Who have Sex with Men and Transwomen: Implications for Rectal Microbicides
(Springer, 2015)
Peruvian men who have sex with men (MSM) and transwomen (TW) could benefit from a rectal microbicide (RM) formulated as a rectal douche to prevent HIV infection. However, little is known about rectal douching practices ...
Bus stops and pedestrian-motor vehicle collisions in Lima, Peru: a matched case-control study
(BMJ Publishing Group, 2013)
OBJECTIVE: To evaluate the relationship between bus stop characteristics and pedestrian-motor vehicle collisions. METHODS: This was a matched case-control study where the units of study were pedestrian crossings in Lima, ...
Economic Burden of Dengue Virus Infection at the Household Level Among Residents of Puerto Maldonado, Peru
(American Society of Tropical Medicine and Hygiene, 2015)
Dengue virus (DENV) was reintroduced to Peru in the 1990s and has been reported in Puerto Maldonado (population ~65,000) in the Peruvian southern Amazon basin since 2000. This region also has the highest human migration ...
Nonlinear dynamic numerical analysis of a RC frame subjected to seismic loading
(Elsevier, 2017-05)
In the context of seismic engineering, reliable modeling methodologies are needed to represent the nonlinear dynamic behavior of structures under the effect of the seismic action. Only in this way is it possible to assess ...
Free expansion of attractive and repulsive Bose-Einstein condensed vortex states
(2002-03-01)
A numerical study of the time-dependent Gross-Pitaevskii equation for an axially symmetric trap to obtain insight into the free expansion of vortex states of BEC is presented. As such, the ratio of vortex-core radius to ...
Modeling of geophysical fluid flows: case of a Peruvian region
(Universidad Nacional Autónoma de Tayacaja Daniel Hernández Morillo - UNATPE, 2021-12-15)
We model mathematically and computationally the geophysical fluid flows, using the basic concepts of rational mechanic and mathematical analysis; then as applications we present the numerical simulation of a rotating of ...
Developmental perspectives of numerical thinking for the interpretation of physical quantities
(IOP Publishing, 2020)
This research reveals the perspectives in the teaching of numerical thinking through a documentary review. The representation of physical elements such as functions, vectors and operators, and their subsequent interpretation ...
Interaction between wave and coastal structure: Validation of two lagrangian numerical models with experimental results marine 2011
(2011-12-01)
Numerical modeling of the interaction among waves and coastal structures is a challenge due to the many nonlinear phenomena involved, such as, wave propagation, wave transformation with water depth, interaction among ...
