Automation of expert decisions in delayed line haul deliveries: an application of the Behavioural Artificial Intelligence Technology

Making decisions regarding delayed line haul transport is a very demanding and complex process in E-commerce distribution centres. Automating this process can decrease decision-maker discussion and assessment time and, as a result, allow decision-makers to spend more time on other demanding tasks like sorting and distributing. Automation in this...

Thin-Film Lithium Niobate Acoustic Delay Line Oscillators

In this work, thin-film lithium niobate (LiNbO₃) acoustic delay line (ADL) based oscillators are experimentally investigated for the first time for the application of single-mode oscillators and frequency comb generation. The design space for the ADL-based oscillator is first analyzed, illustrating that the key to low phase noise...

Low-loss and wideband acoustic delay lines

This paper demonstrates low-loss acoustic delay lines (ADLs) based on shear-horizontal waves in thin-film LiNbO ₃ for the first time. Due to its high electromechanical coupling, the shear-horizontal mode is suited for producing devices with large bandwidths. Here, we show that shear-horizontal waves in LiNbO ₃ thin...

Integrated Temperature Sensors based on Heat Diffusion

This thesis describes the theory, design and implementation of a new class of integrated temperature sensors, based on heat diffusion. In such sensors, temperature is sensed by measuring the time it takes for heat to diffuse through silicon. An on-chip thermal delay can be determined by geometry and the thermal diffusivity of silicon, and since...

Design of Front-End Receiver Electronics for 3D Trans-Esophageal Echocardiography

The motivation behind this thesis is that cardio-vascular diseases claim the highest number of lives each year globally. In order to enhance the accuracy in diagnosis, construction of 3D images of the heart is required. From these images, precise information can be obtained regarding the 3D anatomy of the heart and its functioning. Trans...

Excitation and readout of a thermally driven time-domain optical coherence tomography system

This system presented in this thesis report will be put into practice in a sensory system for dental drilling. The aim of this system is to provide real-time feedback to the practitioner about the anatomical structure in close vicinity of the drill bit. Therefore, the system has to deal with in vivo, in situ bone tissue, bone tissue within a...
