Gradients of histogenesis in the ependymal lining of the third ventricle in the Rabbit
(1986)
Tritiated thymidine autoradiography was used to analyze the site, time of origin, and developmental gradients of the specialized lining of the ependymal surface of the third ventricle. Cells destined to form the ependyma ...
Flowrate independent 3D printed microfluidic concentration gradient generator
(Elsevier Science SA, 2020-02)
Christmas tree like microfluidic concentration gradient generators (MCGG) and other geometries as well, rely on molecular diffusion to achieve concentration gradients. This condition limits the flowrate in the case of ...

The ACS Fornax Cluster Survey. X. Color Gradients of Globular Cluster Systems in Early-type Galaxies
(2011)
We use the largest homogeneous sample of globular clusters (GCs), drawn from the ACSVCS and ACSFCS, to investigate the color gradients of GC systems in 76 early-type galaxies. We find that most GC systems possess an obvious ...
Simulador de escoamento multifásico em poços de petróleo (SEMPP)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2013-02-07)
The multiphase flow occurrence in the oil and gas industry is common throughout fluid
path, production, transportation and refining. The multiphase flow is defined as flow
simultaneously composed of two or more phases ...
Histograma de gradientes orientados utilizando processamento paralelo em GPU
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia de ComputaçãoUTFPR, 2015-07-10)
Feature extraction is fundamental to the process of pattern recognition. In this project a GPU implementation of an image feature descriptor based on local distribution of gradient orientation, the Histograms of Oriented ...
Gradient systems on coupled cell networks
(IOPBristol, 2015)
functions, that is, functions whose gradient is an admissible vector field. The schematic representation of a gradient network dynamical system is of an undirected cell graph, and we use tools from graph theory to deduce ...
Método de gradientes conjugados: um estudo teórico aplicado a quadráticas convexas
(Blumenau, SC, 2019-11-28)
Neste trabalho é apresentado o método dos Gradientes Conjugados. Para isso, foi realizado um estudo sobre o problema de otimização, condições de otimalidade e convexidade, buscando entender os principais
resultados e ...
