The decision-making process towards implementing energy efficiency in a university-built park in southern Brazil

November 26, 2021 Physics & Electrical Engineering No Comments

Sustainability has been increasingly incorporated as an essential life perspective into educational institutions as well as local communities. Universities play an important role into the society by debating theoretical contributions and implementing concrete actions. The present research was developed to evaluate a university’s energy efficiency …..

Determination of differences in dosimetry with and without intravenous contrast media for radiotherapy planning in the anatomical region of the head and neck

November 22, 2021 Radiology & Cancer Therapy No Comments

In radiotherapy (RT), to determine the tumor volume (TV) and its morphology, computed tomography (CT) is used, acquiring images without and with intravenous iodinated contrast media (CM), where its influence has been poorly studied usually in artificial phantoms. Computerized dosimetries without and with CM from …..

How quarantine and social distancing policy can suppress the outbreak of novel coronavirus in developing or under poverty level countries: a mathematical and statistical analysis

November 8, 2021 Mathematics No Comments

In this paper, we develop a novel theoretical model named “Social distancing SEIQR model” to control the spread of infection by combining both quarantine and social distancing explicitly based on the real cases that observed where medical equipment and others resources are limited. COVID-19 is …..

Palindromic, periodic and Möbius Rubik’s snakes

October 19, 2021 Engineering No Comments

A Rubik’s Snake is an interesting toy which can be thought as a serial chain with applications in the construction of reconfigurable modular robots. In this paper, we present some theorems related to a Rubik’s snake with palindromic, periodic and Möbius properties. Examples are given …..
