This thesis describes the design of a 3rd order 1-bit delta-sigma modulator whose input-signal range (0 to 1.95V) exceeds its supply voltage (1.2V). By using a passive input stage and a single-OTA resonator, this beyond-the-rails modulator realizes a 3rd order loop filter with only two amplifiers instead of the usual three and thus achieves...

Technological devices are ubiquitous, think of for example smartphones and in-vehicle information systems. Both can contribute towards distracted driving where the visual field of the human controller is shifted away from the primary control task. In this paper a neural network model is trained using the InceptionTime architecture and used to...

Quantum computers, mainly rely on quantum bits (qubits), which need to be operated at cryogenic temperatures. With the need for systems with thousands or even millions of qubits, the challenges of wiring and scalability become more apparent. To address this, several studies focused on the idea of fully integrated cryogenic controller systems. It...

Cerebral oxygen saturation is an important indicator that reflects the oxygen metabolism of the brain tissues in such patients. The utilization of near-infrared spectroscopy (NIRS) enables the identification of the oxygen saturation levels in nearby tissues by analyzing the distinct oxygenation states of hemoglobin-oxyhemoglobin (HbO2) and the...

Single-photon detection is a critical step in both quantum computing and quantum information technology. For instance, the measurement of qubit states and the establishment of entanglement in nitrogen vacancy (NV) center quantum computing requires the detection of single photons. Superconducting nanowire single-photon detectors (SNSPDs) are very...

Call graphs are useful tools for representing method relationships within software projects and correlations between dependencies. Although static analysis is a prevalent method for call graph construction, it has its limitations such as struggling with handling dynamic features and lambda expressions. In this research, we introduced an approach...

In this work, we deal with the problem of reconstructing a complete bandlimited graph signal from partially sampled noisy measurements. For a known graph structure, some efficient centralized algorithms are proposed to partition the nodes of the graph into disjoint subsets such that sampling the graph signal from any of these subsets leads to a...

This research advocates for exploring the somatosensory system and its incorporation within XR systems, particularly in spatial recognition. This paradigm shift could introduce novel methodologies in XR design that perceive the body as a recipient of sensory stimuli and as an active participant in sensory perception. This could redefine our...

End-to-end Automatic Speech Recognition (ASR) systems improved drastically in recent years and they work extremely well on many large datasets. However, research shows that these models failed to capture the variability in speech production and have biases against the variant caused by the regional accented speech. Moreover, ASR research on...

Poly-hydroxy-alkanoate (PHA) is an intracellular polymer that can be used as an energy and carbon source by microorganisms. Measuring PHA is important for understanding the microbial metabolism of enhanced biological phosphorus removal (EBPR) and aerobic granular sludge (AGS) systems. There is a commonly used method to measure PHA, which is...

Concurrency bugs are easy to introduce but dif- ficult to detect, especially in implementations of distributed algorithms where concurrency non- determinism is an inherent problem. These bugs may only be identified under very specific order- ings of execution events, making them challenging to reproduce. Controlled concurrency testing tech-...
