An electric micro-resistance sensor that can continuously measure the deformability of a single red blood cell (RBC) in a microchannel and a numerical model that can simulate the resistance and capacitance of the cell membrane and cytoplasm are developed and improved. The resistance ... Read More

The scientific method requires techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge [1]. The Oxford English Dictionary defines the scientific method as "a method or procedure that has characterized natural science since the ... Read More

Underwater acoustics is an area that studies the sound propagation in water and the interactions with other objects and water boundaries. There are many technologies available for acoustic exploration of the ocean. Underwater vehicles are robots used in ocean sciences that travel ... Read More

Electromagnetic and thermal simulations are achieved using COMSOL Multiphysics® with 2D axisymmetrical finite–element method for a percutaneous microwave hyperthermia system with ex–vivo experiments on different biological tissues. Temperature variation and distribution are studied in ... Read More

This work describes the implementation with COMSOL Multiphysics® of a thermal simulation of a space environmental chamber, the SpaceQ chamber [1]. Space environment facilities are needed to simulate on Earth the expected performance of hardware and instrumentation that shall operate in ... Read More

Capacitor is mainly defined as two conducting plates that can hold the opposite charges on it. These plates can be used either as a sensor or an actuator. If the relative distance between the two conductors changes as result of given input, then capacitance values will change. This ... Read More

Dynamic measurement of magnetic particles in continuous flow devices is made very difficult by the limitations imposed by the sensors themselves. Thus, certain sensor layouts are restricted to either number sensitive or spatial resolutive measurements of magnetic particles. We ... Read More

The possibility to detect and probe molecules in microfluidic devices gives rise to interesting applications. There are different approaches how to detect and probe particles, but a common step, for most methods, is to place the particles on a sensor. This can be done by applying ... Read More

Here we optimize the geometry: proof mass length Lm to total length L, thickness of the piezoelectric material (Tp) to total cantilever thickness (T) for obtaining the maximum stress distribution (Smax), output voltage (Vout) and power performance (Pout) of the unimorph Cantilever beam ...

Offshore operations, using Robotically Operated Vehicles (ROVs) in areas with high ambient temperatures require ampacity limitations to be established. Specifically, the risk of overheating ROV umbilicals and tethers when running at high power, due to multiple layers on winch drums is a ... Read More
