A Performance Comparison between Different Industrial Real-Time Indoor Localization Systems for Mobile Platforms.

The flexibility and versatility associated with autonomous mobile robots (AMR) have facilitated their integration into different types of industries and tasks. However, as the main objective of their implementation on the factory floor is to optimize processes and, consequently, the time associated with them, it is necessary to take into account the environment and congestion to which they are subjected. Localization, on the shop floor and in real time, is an important requirement to optimize the AMRs' trajectory management, thus avoiding livelocks and deadlocks during their movements in partnership with manual forklift operators and logistic trains.

Splenomesenteric bypass as revascularisation technique after iatrogenic injury of the superior mesenteric artery during radical nephrectomy: A case report.

Introduction: Iatrogenic vascular injuries during radical nephrectomy are rarely reported. In the case of an injury of the superior mesenteric artery, the consequences for the patient are potentially catastrophic. It occurs more frequently in patients with large renal tumors, due to the presence of bulky perihilar adenopathies, or in cases of pyelonephritis.

Multistage spectral relaxation method for solving the hyperchaotic complex systems.

We present a pseudospectral method application for solving the hyperchaotic complex systems. The proposed method, called the multistage spectral relaxation method (MSRM) is based on a technique of extending Gauss-Seidel type relaxation ideas to systems of nonlinear differential equations and using the Chebyshev pseudospectral methods to solve the resulting system on a sequence of multiple intervals. In this new application, the MSRM is used to solve famous hyperchaotic complex systems such as hyperchaotic complex Lorenz system and the complex permanent magnet synchronous motor.

Profile of patients with lung cancer assisted at the National Cancer Institute, according to their smoking status, from 2000 to 2007.

Introduction: Tobacco use is directly related to the future incidence of lung cancer. In Brazil, a growing tendency in age-adjusted lung cancer mortality rates was observed in recent years.

Objective: To describe the profile of patients with lung cancer diagnosed and treated at the National Cancer Institute (INCA) in Rio de Janeiro, Brazil, between 2000 and 2007 according to their smoking status.
