Quantifying Biomedical Amplifier Efficiency: The noise efficiency factor

There has been a long-standing interest in controlling and instrumenting the human body. Whether to restore lost function with neural prosthetics, monitor blood glucose levels, or augment human capabilities, there are countless opportunities for sensors inside ( e.g., ingestible, injectable, and implantable) and outside ( e.g., wearable) the...

An Intriguing Relation Between the Power Consumption and Number of Antenna Elements in Multi-Beam Phased Arrays

An improved system-level power consumption model (PCM) for 5G base station multi-beam phased-array transmit architectures is developed. Using this model, it is shown that an optimum number of antenna elements of the array exists with respect to the total power consumption. The proposed model is benchmarked against a recent study which is shown...

Risk-averse Estimation of Electric Heat Pump Power Consumption

An important aspect of the energy transition is the expected grid impact due to the abrupt increase of distributed electric generation and electric load demand. A part of this impact is going to be inflicted by the electrification of heating with heat pumps (HPs). Therefore, it is essential that the future power consumption of electric...

Power Consumption Analysis of 5G Transmit Antenna Topologies and Beamforming Schemes

An exponential growth in the mobile communications industry over the past decade has raised concerns over it’s energy consumption, especially in light of the current climate crisis. 5G technologies in particular exhibit features that imply high power consumption, such as the densification of 5G base stations. Implementing mitigation measures...

Speed-Power Improvement in High-Voltage Switches Employed in Multi-Electrode Arrays

In multi-electrode arrays (MEAs), for electrical recording and electrical stimulation, high voltage (HV) switches are employed to build an analog multiplexer to conduct either a HV stimulation signal from the pulse generator circuit to an electrode or a low-voltage noise-sensitive signal from the electrode to a recording stage. In this brief,...

Would Magnonic Circuits Outperform CMOS Counterparts?

In the early stages of a novel technology development, it is difficult to provide a comprehensive assessment of its potential capabilities and impact. Nevertheless, some preliminary estimates can be drawn and are certainly of great interest and in this paper we follow this line of reasoning within the framework of the Spin Wave (SW) based...

Energy Consumption and Scalability of Transmitting Firmware Updates Over LoRa

The rapid growth of LoRa sensor networks lead to more and more maintenence challenges. One of them is wirelessly updating the firmware, especially for the ones that are hard or dangerous to reach. Is it feasible to do a firmware update over LoRa, and what is its additional power consumption of the wireless sensors? In this thesis a LoRa Class B...

Energy-aware noise reduction for wireless acoustic sensor networks

In speech processing applications, e.g., speech recognition, hearing aids (HAs), video conferencing, and human-computer interaction, speech enhancement or noise reduction is an essential front-end task, as the recorded speech signals are inevitably corrupted by interference, including coherent/incoherent noise and reverberation. Traditional...

Technical feasibility study for slurry transport of the Atlantis II deep-sea mining field

Deep-sea mining is becoming more popular. The Atlantis II Deep is a deep sea mining field of metalliferous muds in the Red Sea. This field could be exploited by transporting the sediments through a pipeline laid from shore onto the sea bed to the field. From determined concentrations with their shear stress-shear rate relation, parameters for...

Designing a self sustaining tracker

Currently location trackers for valuables have a short battery life, demanding an intensive battery maintenance experience of the user. Discharged batteries mean a malfunctioning product, resulting in a false sense of security by the user. The incentive of this thesis is to explore the opportunities in energy harvesting technologies, low power...

On the prediction of residential loads in India

The Indian Energy grid is growing rapidly and there is a large simulation to improve not only the grid reliability, but also provide power for all by 2027. To this aim the Government of India has launched the Restructured Accelerated Power Development Program (RAPDRP). In India, residential loads contribute to about 27% of the total power...

Energy Saving in Bluetooth 4.0 Wireless Locks Connected via Mobile Phone to the Internet

In a modern environment users are more dependant on their ability to use their mobile phone for nearly everything. They communicate with almost any device and those devices provide nearly limitless access to for instance a watch or in new applications, a lock. Issues encountered with these devices are the almost always lack the ability to keep...
