"We report experimental results on the competitive passage of elongated self-propelled vehicles rushing through a constriction. For the chosen experimental conditions, we observe the emergence of intermittencies similar ...

"Several works have addressed the issue of fault tolerance in multirotors in case of a rotor total failure, particularly their ability to keep full independent control of attitude and altitude. It has been proven that to...

"We study experimentally the properties of the flow of mechanical vibration-driven vehicles confined in two chambers connected through a narrow opening. We report that the density of particles around the opening presents...

"In the last years, progress has been made attempting to replace a unique, complex and expensive vehicle equipped with several sensors such as LIDAR, RGB cameras, thermal sensor, etc. with a group of small vehicles, each...

"The thermochemical decomposition of beech wood biomass results in a poor quality bio-oil, which cannot be directly used in diesel engines. In order to make this oil resemble liquid fossil fuels, an upgrading technique s...

The objective of this work was to investigate feasibility of transdermal delivery of loratadine. Effect of pH, vehicles and chemical enhancers on the skin permeation of loratadine was studied in vitro, using rat abdomina...

"The high emissions of greenhouse gases and the impact generated on the environment by human behavior during the last few years has led many governments to decide to promote the use of electric cars for passenger transpo...

Vehicles and enhancers effect on in vitro probenecid permeation through dermatomed abdominal pig skin was investigated. The permeability of different probenecid percentages dispersed in vehicles as vaseline, carbopol/e...

"There is an increasing interest in replacing a unique, complex, and expensive vehicle equipped with several sensors with a group of small vehicles, each of them carrying fewer sensors. There are several advantages in th...

Solubility represents a limiting factor when testing new compounds in animal experiments, since solubilizing agents generally have pharmacological effects that can interfere with the studied substance. Vehicles are com...

"This thesis evaluates the technical, economic and environmental performance of a hydrogen fueled hybrid bus, which uses an internal combustion engine as a power unit. Results are compared to those of a conventional dies...

"The transportation sector has become one of the most important sources of greenhouse gases (GHG) emissions and energy consumption in the world, and such emissions have impact in the global warming. For that reason, gove...

"This article proposes an integrated navigation system for multiple micro aerial vehicles flying in formation. A data fusion algorithm uses measurements from an inertial measurement unit, a GPS receiver, and a camera all...
