1. Step-by-step optimisation of robotic-assisted radical prostatectomy using augmented reality
ABSTRACT Introduction: Surgical training will be complemented by digitalisation, as the COVID 19 pandemic continues (1). Proximie is an augmented reality (AR) platform that can display up to 4 native camera views, with live or semi live telementoring. It can optimise ergonomics of the surgeon at the console (2), and robotic instrument orientation. We descri

2. El Sistema Informático de la Reforma GES en Chile: una etnografía de dispositivos de gobierno sanitario
Resumo Nas últimas décadas, as tecnologias da informação foram incorporadas aos sistemas de saúde por meio da criação de "redes assistenciais", que devem integrar diferentes níveis, instituições e agentes. No Chile, o regime de "garantias explícitas em saúde" (GES) liga-se a essas reformas modernizadoras do Estado, cujo objetivo é melhorar a efi

3. Influence of film coefficient during multicomponent diffusion – KCl/NaCl in biosolid for static and agitated system using 3D computational simulation
Abstract The influence of film coefficient formed during the diffusion of inorganic salts (NaCl and KCl) in biosolids was studied using a 3D computer modeling by Finite Elements Method (FEM) in COMSOL Multiphysics® software combined with SOM-type Artificial Neural Networks (ANN). Such tools have shown that the influence of the film formed in the biosolid/s

5. Contribution of the CASA system, based on open source software, to the assessment of sperm characteristics: informetric and usage-based approaches
ABSTRACT By using informetric tools, we evaluated the contribution and impact of the open source computer-assisted sperm analysis (CASA) software on sperm studies, especially pertaining to fish. The article was cited 125 times between 2007 and 2014 in four publication types (articles, doctoral dissertations, master’s theses, and books). Among articles, the

6. Breast tumor classification in ultrasound images using support vector machines and neural networks
Abstract Introduction The use of tools for computer-aided diagnosis (CAD) has been proposed for detection and classification of breast cancer. Concerning breast cancer image diagnosing with ultrasound, some results found in literature show that morphological features perform better than texture features for lesions differentiation, and indicate that a reduc

7. Spatial Interpolation of Rainfall Erosivity Using Artificial Neural Networks for Southern Brazil Conditions
ABSTRACT Water erosion is the process of disaggregation and transport of sediments, and rainfall erosivity is a numerical value that expresses the erosive capacity of rain. The scarcity of information on rainfall erosivity makes it difficult or impossible to use to estimate losses occasioned by the erosive process. The objective of this study was to develop

9. All-optical cryptography through spectral amplitude and delay encoding
All-optical data encryption is a promising technology that could lead communication systems to an unprecedented degree of security. In this paper we use computer simulations to systematically investigate a new all-optical cryptography technique that is bit-rate independent and transparent to modulation formats. Encryption encompasses signal spectral slicing

12. Projeto e avaliação de desempenho de torres de resfriamento de água utilizando redes neurais artificiais = : Design and analysis of cooling towers using neural netwoks / Design and analysis of cooling towers using neural netwoks
Em muitos processos há necessidade de remover a carga térmica de um dado sistema e utiliza-se, na maioria dos casos, a água como o fluido de resfriamento. Devido à sua crescente escassez e preocupação com o meio ambiente, além de motivos econômicos, a água "quente" que sai desses processos, deve ser aproveitada. Para tanto, ela passa por uma torre d
