Development of a Test-Bench for the Accurate Positioning of Scintillation Detector Modules for Medical Imaging Applications
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2018)
When assessing the impact of novel concepts of scintillation block detectors for PET tomography by measuring the performance of single modules, or one module in coincidence with another, it is not trivial to translate the ...
A Proposal for a Formula of Absolute Pole velocities between Relative Poles
(Elsevier, 2017-04-10)
In this paper is proposed a vectorial equation that relates the absolute pole velocities of three moving rigid
bodies with a planar motion of general type. From this equation, it is possible to obtain a relation between ...
Control Distribution of Partially Decoupled Multi-level Manipulators with 5 DOFs
(Cambridge University Press, 2017-02-01)
Multi-level manipulators are those mechanisms in which two or more levels,
that de ne the main chain of the manipulator, are joined in parallel to
each other. Besides, each level is linked to the base in parallel by ...
A robot for welding inspection in offshore mooring chains
(Springer, 2018-08-31)
In this paper, the authors present the CIRUS robot. This automatic system uses a combination of pulse-echo and pitch and catch ultrasonic strategies for the inspection of the welded area of mooring chain links in an automatic ...
A robot for non-destructive testing weld inspection of offshore mooring chains
(SAGE Publications Inc., 2018-05-09)
Welding flaw detection is a key step in manufacturing many components. In offshore chains, every link is manufactured from a steel bar that is bent and the ends joined by flash butt welding. Ultrasonic inspection of the ...
Structural Synthesis of 3-DoF Spatial Fully Parallel Manipulators
(Intech Europe, 2014-07-16)
In this paper, the architectures of three degrees of freedom (3-DoF) spatial, fully parallel manipulators (PMs), whose limbs are structurally identical, are obtained systematically. To do this, the methodology followed ...
A Comparison of Numerical Approaches for the Design of Mooring Systems for Wave Energy Converters
(MDPI, 2020-07-16)
This paper analyses the numerical outcome of applying three different well-known mooring design approaches to a floating wave energy converter, moored by means of four catenary lines. The approaches include: a linearized ...
Insights into mechanism kinematics for protein motion simulation
(Biomed Central, 2014-06-12)
Background: The high demanding computational requirements necessary to carry out protein motion simulations make it difficult to obtain information related to protein motion. On the one hand, molecular dynamics simulation ...
Translational parallel manipulator with Pa2 kinematic joints
(Springer, 2016-10-01)
The kinematic pair Pa2 is composed of two interlinked parallelograms. It has two degrees of freedom that generate a translational plane variable with position. It has a structure different from the PaPa pair, which is ...
Design of an active reconfigurable 2R joint
(Springer, 2019-06-14)
The increasing flexibility requirements in the manufacturing processes has led to the development of novel reconfigurable mechanisms to be implemented in ma-chine heads and tables. This is the case of the reconfigurable ...
