During the last years, electric power generation was based mainly on large centralized fossil fuelled power plants. However, nowadays and in the future, efforts are made to increase the share from renewable sources, as a result of increasing environmental concern. Indeed, in some networks areas, wind generators gradually start to replace...

In this report the finger vibrotactile subsystem of the SoftGlove wearable haptic feedback glove is discussed. This system is an upgrade over the vibrotactile feedback that the current SenseGlove haptic feedback glove provides. The designed system consists of a linear resonant actuator (LRA) on each finger, which is controlled by a dedicated LRA...

External Quantum Efficiency (EQE) is an important performance measure parameter of a solar cell. EQE characterization gives deeper insights into the opto-electrical properties, current generation and recombination mechanisms in solar cells. Conventional EQE characterization of solar cells are done using a monochromator and lock-in amplifier....

Recent projections estimate that the Netherlands needs circa 33 GW of offshore wind capacity in the North Sea to meet the goals of the Paris Agreement. To this end, the Dutch government has very ambitious plans to create new wind sites far from shore and integrate that power generation to the high-voltage power grid in the next years. Due to the...

Over the last 50 years, the global airline industry has seen resilient growth in the demand for passenger travel; this trend is expected to continue in the coming decades. With kerosene being the predominant source used as jet fuel, this increase in air traffic is expected to result in the depletion of non-renewable fossil fuels and undesired...

Eddy currents are loops of electrical currents induced within conductors by varying magnetic field in the conductor. Eddy currents flow in the closed loops in the conductor, in planes perpendicular to the magnetic field. The eddy current effect plays an important role in the transformer or an actuator system. <br/>If there is a coil wound around...

One of the most important aspects to consider when a PV system will be mounted, is the PV panel’s orientation in order to receive the highest amount of solar radiation and thus produce as much energy as possible. This is achieved by tilting the solar panel to an optimal angle (which depends of the location’s latitude) or by tracking systems...

Tidal energy is one of form through which renewable energy can be extracted from oceans which covers more than 70% of the earth surface. Tides are a periodic function and can be predicted for a long period this makes tidal energy more favorable than other ocean energy. To prevent the sealing problems associated with the tidal generators the...

There are two existing surface passivation principles. Passivation of unsaturated Si bonds is called chemical passivation. Surface passivation can also be achieved by shielding the minority charge carriers from the semiconductor interface by means of an electric field. This method is referred to as field-effect passivation. <br/>To test the...

In a cordless kitchen system, the appliances do not make use of a power cord. The system consists of a power channel and a communication channel. There are various resonant topologies which can be implemented in the power channel[9]. The chosen topology should meet the functional as well as non-functional equirements of the system. Presently, a...
