Future communication scenarios will require massive Multiple-input multiple-output (MIMO) by the use of multi-beam antenna systems. Maximizing the number of beams for a given antenna size is paramount given that the space allocated to the antenna is often limited. This work aims at evaluating the maximum number of beams by analyzing the SIR in...

Over the years, care givers in nursing homes have seen their workload gradually increase. With no end of this trend in sight, the need for smart support systems increases. Especially systems which decrease the time spent on menial tasks are valued highly, because this frees more time for high quality and personal care.<br/>To achieve this, Momo...

To make open door policies easier in nursing homes, it is important to have a smart system that can check whether access is allowed for the person trying to enter some place or not. This thesis documents how an access control system has been built, for Momo Medical, to be used at a nursing home. It sheds light on hardware considerations made and...

Due to the precise lithography and highly pure silicon used in IC technology, thermal-diffusivity (TD) temperature sensors can achieve high accuracy without the need for trimming. TD sensors employ electrothermal filters (ETFs) to measure the thermal diffusivity of silicon, i.e. the rate at which heat diffuses through silicon, which is a well...

The inverse shortest path problem (ISPP) is a problem based on graph theory, that is to design link weights in a graph to satisfy that given paths are the shortest between the corresponding node pairs. It can be used in networks of complex systems to solve practical problems such as re-routing in transportation systems and reallocating resources...

Global electricity usage has been increasing exponentially over the last 40 years and with the current pace of population and economic growth, the same trend will continue in the coming years. However, the current electricity generation is predominantly fossil fuels based, which makes the overall process unsustainable and polluting, and is...

Sensors are extremely valuable to this world. Without sensors, we would not be able to live as we do in this data-driven environment. Therefore, finding new ways to measure the matter around us is a continuous process. In this work, an addition to the new sensors is attempted, using materials that can withstand the most extreme circumstances....

Emission of ammonia and nitrogen oxides puts pressure on vulnerable ecosystems in The Netherlands. Satellite data from TROPOMI and CrIS gives vertical column density (VCD) maps for nitrogen dioxide and ammonia respectively. The Flux-Divergence method converts a VCD map to an emission map, by temporally averaging the divergence of the flux of the...

The electrification of modern-day society keeps increasing and the demand for electricity grows along with it. Technologies like EVs and heat pumps are both part of the new types of demand, while PV systems and wind farms are meant to be our main new sources of generation. Contrary to traditional resources connected to the electricity network,...

Time-of-Flight (ToF) is an optical range detection technique that derives range from the round-trip time of light pulse between the imager and the target. Due to the simple hardware and distance extraction algorithm, ToF imagers are widely adopted in existing (automotive, consumer electronics, etc.) and emerging (AR/VR, etc.) applications...

A minimal Kitaev chain can be realized by coupling two quantum dots to a superconductor on both sides. Andreev Bound States inside the superconductor mediate two types of interdot couplings: Cross Andreev Re ection (CAR) and Elastic Co-tunneling (ECT). Spin-orbit interaction (SOI) enables equal strengts of CAR and ECT, where Majorana Bound...

Nowadays, recent Integrated Circuit Technology demands a minimum metal fill inclusion across the entire die of each functional layer to have uniform planarity. It is challenging to numerically simulate the real structure using Electromagnetic (EM) solvers because the mesh size of an EM solver is inversely proportional to the number of vertices...

Background &amp; Objective<br/>Cardiovascular diseases (CVDs) are the leading cause for death globally nowadays. Pulse wave velocity (PWV), a marker of arterial stiffness, is an important predictor of CVD risk. In precedent work, carotid artery data was collected with ultrasound to estimate the PWV with a digital signal processing (DSP) pipeline...

This paper presents a 0.01mm2 10MHz FLL-based RC frequency reference that does not require the use of resistors with complementary temperature coefficients (TCs), thus facilitating its implementation in a wide range of standard CMOS processes. Fabricated in a 0.18μm CMOS process, it achieves a frequency inaccuracy of ±0.28% from −45°C to 125°C...

Implantable Medical Devices (IMDs) offer a wide range of applications including but not limited to blood pressure monitoring, bladder pressure sensing, glucose level monitoring, neurostimulation etc. For such applications, it is often desired that an IMD is as small as possible while meeting the required objective. Consequently, using a battery...

Whereas in the past, the Distribution System Operator (DSO) almost never encountered congestion in their grids, nowadays, with the increase of connected renewable energy sources, this will become more prevalent. To forecast congestion on transformer stations, with the goal of mitigating it, the Dutch DSO Stedin uses machine learning models with...

Class-D amplifiers are quickly becoming the standard in many audio applications. Their highly efficient behavior and wide power range make these amplifiers more suitable than traditional Class A/AB audio amplifiers. Battery-powered devices are a particularly interesting sub-field due to their special demand for extended battery duration and...

Class D audio amplifier is widely used in many electronic applications such as automobiles, laptops, and mobile phones. However, electromagnetic interference (EMI) generated by Class-D audio amplifiers frequently requires an external LC filter for suppression. The LC filter itself causes significant nonlinearity. Hence, feedback after LC is...
