RESTful Discovery and Eventing for Service Provisioning in Assisted Living Environments
(MDPI, 2014-05)
Service provisioning in assisted living environments faces distinct challenges due to the heterogeneity of networks, access technology, and sensing/actuation devices in such an environment. Existing solutions, such as ...
Fiber Bragg Gratings, IT Techniques and Strain Gauge Validation for Strain Calculation on Aged Metal Specimens
(MDPI, 2011-01)
This paper studies the feasibility of calculating strains in aged F114 steel specimens with Fiber Bragg Grating (FBG) sensors and infrared thermography (IT) techniques. Two specimens have been conditioned under extreme ...
Design and Development of a Low-Cost Optical Current Sensor
(MDPI, 2013-10)
In this paper we demonstrate the design of a low-cost optical current sensor. The sensor principle is the Faraday rotation of a light beam through a magneto-optical material, SF2, when a magnetic field is present. The ...
A Temperature Sensor Based on a Polymer Optical Fiber Macro-Bend
(MDPI, 2013-10)
The design and development of a plastic optical fiber (POF) macrobend temperature sensor is presented. The sensor has a linear response versus temperature at a fixed bend radius, with a sensitivity of 1.92.10(-3) (degrees ...
Proof of Concept of Impact Detection in Composites Using Fiber Bragg Grating Arrays
(MDPI, 2013-09)
Impact detection in aeronautical structures allows predicting their future reliability and performance. An impact can produce microscopic fissures that could evolve into fractures or even the total collapse of the structure, ...
An Optical Fiber Bundle Sensor for Tip Clearance and Tip Timing Measurements in a Turbine Rig
(MDPI, 2013-06)
When it comes to measuring blade-tip clearance or blade-tip timing in turbines, reflective intensity-modulated optical fiber sensors overcome several traditional limitations of capacitive, inductive or discharging probe ...
Feedback on the Rate and Depth of Chest Compressions during Cardiopulmonary Resuscitation Using Only Accelerometers
(Public Library Science, 2016-03-01)
Background
Quality of cardiopulmonary resuscitation (CPR) is key to increase survival from cardiac arrest. Providing chest compressions with adequate rate and depth is difficult even for well-trained rescuers. The use ...
PAnalyzer: A software tool for protein inference in shotgun proteomics
(BioMed Central, 2012-11-05)
Background
Protein inference from peptide identifications in shotgun proteomics must deal with ambiguities that arise due to the presence of peptides shared between different proteins, which is common in higher eukaryotes. ...
Simplified Formulae for the Estimation of Offshore Wind Turbines Clutter on Marine Radars
(Hindawi Publishing, 2014)
The potential impact that offshore wind farms may cause on nearby marine radars should be considered before the wind farm is installed. Strong radar echoes from the turbines may degrade radars' detection capability in the ...
