A feasibility study on incremental bundle adjustment with fisheye images and low-cost sensors
(2019-01-01)
Low cost imaging and positioning sensors are opening new frontiers for applications in near real-time Photogrammetry. Omnidirectional cameras acquiring images with 360° coverage, when combined with information coming from ...
Geogrid creep and tensile tests performed with nonconventional equipment
(2014-01-01)
Creep behavior of geosynthetics is commonly determined by means of creep tests performed with in-isolation specimens. Soil-geosynthetic interaction and duration of the tests were already addressed in previous studies with ...
Virtual instrumentation applied to the implementation of IEEE STD 1459-2000 power definitions
(2005-12-01)
This paper discusses the utilization of Virtual Instrumentation to the implementation and evaluation of different power definitions, so that classical formulations and new definitions can be compared without the necessity ...
Detection of Simultaneous Faults Using State Observer Methodology
(2021-01-01)
Due to the big interest of industries in predictive maintenance, the development of techniques to diagnose failures has been gradually acquiring a relevant role in the current industrial scenario. For this reason, this ...
Power performance evaluation of an electric home fan with triac-based automatic speed control system
(2009-12-01)
In order to provide a low cost system of thermal comfort, a common model of home fan, 40 cm diameter size, had its manual four-button control system replaced by an automatic speed control. The new control system has a ...
Design of a control system based on EIT sensors: An optimization approach
(2015)
Sensor based on Electrical Impedance Tomography has been developed to address the need of nonintrusive measurements for a wide range of applications such as: sedimentation, mixing, interface detection and concentration ...
Development of advanced algorithm for measuring bone densitybased on radio graphic densitometry
(Ieee, 2016-01-01)
Radiographic densitometry is a technique that allows us to evaluate bone density, using as reference an inert material, such as aluminum. Those techniques allow for the support of the diagnosis of diseases and bone ...
A genetic neuro-model reference adaptive controller for petroleum wells drilling operations
(2007-12-01)
Motivated by rising drilling operation costs, the oil industry has shown a trend towards real-time measurements and control. In this scenario, drilling control becomes a challenging problem for the industry, especially due ...
