An empirical framework to applying unit testing in operational research
(Curran Associates Inc., 2018-12)
Operational Research (OR) models usually deal with uncertain, changing requirements. This leads to a continuous process of adapting and reworking the mathematical code. However, there are scarce mechanisms to control its ...
Real-time physical engine for floating objects with two-way fluid-structure coupling
(IDOSI, 2013-06)
A method to simulate graphic animations of objects floating in a water surface in real time is presented. The fluid is simulated by means of the Lattice Boltzmann method for the shallow-waters equations, and the movement ...
Simulation and testing of a solar reciprocating steam engine
(Pergamon-Elsevier Science Ltd, 2018-05-15)
A solar thermal system for steam generation was built in the city of San Carlos, Salta province, Argentina. This system is a Linear Fresnel Collector (LFC) used for producing steam for many applications, such as vegetable ...
Design and construction of a Stirling engine prototype
(Pergamon-Elsevier Science Ltd, 2008-07)
In this work an external combustion engine is presented, which was designed through principles of energetic similarity and scaling, combined with adiabatic simulation, pressure loss and heat exchange characteristics analysis. ...
Multimodal piezoelectric device for energy harvesting from engine vibration
(Mathematical Science Publ, 2018-04-07)
In a conventional transport vehicle, only about 10% to 16% of the energy from the fuel is used to move it down the road. The rest of the energy is lost in the brakes, transmission, engine, accessories, rolling resistance, ...
Cordgrass canopy elicits weak effects on sediment properties and microphytobenthic abundance in a harsh environment
(Inter-Research, 2016-05)
The magnitude of the outcome of ecosystem engineering is context-dependent; asenvironmental stresses increase, habitat amelioration by ecosystem engineers becomes more relevant. Moreover, the individual- and population-level ...
Model-based run-to-run optimization for process development
(Brazilian Society of Chemical Engineering, 2018-07)
Research and development of new processes is a fundamental part of any innovative industry. For process engineers, finding optimal operating conditions for new processes from the early stages is a main issue, since it ...
An ontology for specifying and tracing requirements engineering artifacts and Test Artifacts
(Centro Latinoamericano de Estudios en Informática, 2019-04-01)
Nowadays, modern software development processes follow an iterative approach, which makes possible to start the testing of a system at early stages. This approach requires recording the requirements artifacts that specify ...
Engineering by an invasive species alters landscape-level ecosystem function, but does not affect biodiversity in freshwater systems
(Wiley, 2014-02)
Aim: Ecological theory predicts that invasive ecosystem engineers like the American beaver (Castor canadensis) in Tierra del Fuego (TDF) affect landscape-level biodiversity and ecosystem function (BEF) when engineered ...
Pilot testing of a bioremediation system of water and soils contaminated with heavy metals: vegetable depuration module
(Taylor & Francis, 2019-03)
We present a novel constructed wetland called a vegetable depuration module (VDM) as a pilot test of a bioremediation system (BS) for decontaminating water and soil polluted with heavy metals. The VDM consisted of a pool ...
