Influência de cortes no comportamento mecânico de paredes em alvenaria estrutural submetidas à compressão
(Universidade Federal de Santa Maria, 2019-09-13)
Chases in masonry walls with no design prediction are often found in Brazilian buildings, usually for electrical, hydraulic, gas, air-conditioning, and other installations. As the wall is the supporting element in this ...
Comportamento mecânico, funcional e ambiental de misturas asfálticas porosas
(Universidade Federal de Santa Maria, 2019-10-07)
Road transportation is the main means of transportation in Brazil and it is also known
that about 90% of paved roads have asphalt concrete as a coating layer. When it
comes to OGFC (Open-Graded Friction Course) hot ...
Influência do módulo de finura nas proprieades de argamassas com aditivo incorporador de ar
(Universidade Federal de Santa Maria, 2019-08-15)
The characteristics of the fine aggregate that are present in mortar composition
significantly influence the properties of the mortars, and may change the application
yield and performance in the hardened state. Using ...
Contribuição para a previsão empírico-mecanicista da irregularidade longitudinal e seus desdobramentos econômicos em pavimentos asfálticos
(Universidade Federal de Santa Maria, 2019-05-03)
The guarantee of ride quality conditions with safety and comfort is one of the main objectives during a road structure design. A road functional behavior is evaluated quantitatively by indexes that determine, among other ...
Determinação das características do solo visando o aproveitamento geotérmico como fonte renovável de energia
(Universidade Federal de Santa Maria, 2019-03-29)
Knowledge of the soil thermal characteristics is indispensable for dimensioning geothermal
exchangers for air conditioning or yet to decrease their electric consumption. The present
thesis evaluates the geothermal potential ...
Diagnóstico energético em sistema de climatização (self contained) de um laboratório de pesquisas com nível de biossegurança NB-2
(Universidade Federal de Santa Maria, 2019-02-16)
Recent studies have shown that a large portion of the electric energy consumed in
Brazil is destined to commercial and public buildings. Noting that the HVAC (Heating
Ventilation and Air Conditioning) system plays a ...
Avaliação do desempenho dos métodos de proteção contra a perda de excitação em geradores síncronos: uma contribuição para a melhoria da técnica baseada em combinações de sinais
(Universidade Federal de Santa Maria, 2019-07-19)
This work aims to evaluate the behavior of synchronous generators against total (TLOE)
and partial (PLOE) loss of excitation, to demonstrate the behavior of the main electrical variables
involved, to analyze the performance, ...

(Universidade Federal de Santa Maria, 2019-08-19)
People with disabilities and reduced mobility, beyond the medical and individual perspective, associate themselves to a structural and social perspective, where the interaction environment has a huge impact on the experience ...
Circuito para monitoramento e restabelecimento da tensão elétrica em células a combustível tipo PEM usando curtos-circuitos controlados
(Universidade Federal de Santa Maria, 2019-03-31)
Electricity generation from renewable sources can contribute significantly to mitigate the impacts that non-renewable sources have on nature. Of these, hydrogen power generation is of great interest and can be easily ...
Estudo de concretos com pozolanas submetidos à carbonatação em ensaios acelerado e natural monitorado por 20 anos
(Universidade Federal de Santa Maria, 2019-09-02)
Carbonation, a potentially aggressive chemical reaction to concrete, is a slow process and difficult to detect in the short term through accelerated testing. In this work were studied concretes with fly ash (CV) and rice ...
