Urban heat island analysis over the land use zoning plan of Bangkok by means of Landsat 8 imagery

Surface urban heat island (SUHI) maps retrieved from spaceborne sensor data are increasingly recognized as an efficient scientific support to be considered in sustainable urban planning. By means of reflective and thermal data from Landsat 8 imagery in the time interval 2014-2016, this&...

Meta-analysis of perioperative outcomes of acute laparoscopic vs open repair of perforated gastroduodenal ulcers

Surgery is the treatment of choice for perforated peptic ulcer disease (PUD). The aim of the present review is to compare the perioperative outcomes of acute laparoscopic versus open repair for PUD.

Solving numerically nonlinear systems of balance laws by multivariate sigmoidal functions approximation

A numerical method for solving systems of nonlinear one-dimensional balance laws, based on multivariate sigmoidal functions approximation, is developed. Constructive approximation theorems are first established in both, uniform and $L^p$ norms. A priori as well as a posterior...
