description: The “Stabilized Reference Cavity and Laser Lock” project is intended to produce a laser which is locked to a cavity in order to produce a significantly smaller bandwidth (or, in optical terms, “linewidth”) than the laser could normally achieve. The project was undertaken by Tenny Gao, Rudy Lam, and Andrew Cavers between September 26 2011 and January 10 2012. The overall goal of the project was to couple light from an 899-21 titanium sapphire ring laser (Ti:Sapph) into a cavity and use the transmission intensity through the cavity as error feedback to lock the laser to a specific frequency. The overarching tasks required to reach this goal were to assemble the Ti:Sapph laser, characterize the cavity, and test the quality of the laser lock. The deliverables of the project were: 1. Buying or building control electronics which allow the Ti:Sapph to be controlled by a user and by a feedback signal from a cavity. Deliverable A was found to be unnecessary, as a control electronics box (or "lockbox") was provided by the sponsor to control the laser. It was later found that this lockbox was broken in some way and required repair. 2. Assembling and bringing the disassembled 899-21 laser in the sponsor's lab into narrowband lasing. This deliverable was unattainable because although the 479 group brought the 899-21 laser into broadband lasing, the component required for narrowband lasing (the inter-cavity assembly, or ICA) could not be mounted into the laser and allowed to lase at the same time. The team ultimately resorted to locking another, identical Ti:Sapph laser in the sponsor's lab. 3. Locking the titanium sapphire ring laser onto a cavity, which in turn must be locked onto a frequency comb laser. Deliverable C was found to be impossible without replacing the initial cavity selection with a more stable cavity. The cavity the 479 group attempted to lock to was found to drift as quickly as 100 MHz a minute, endlessly. 4. Using an acousto-optic modulator to further correct the signal of the cavity-locked laser, using feedback from the cavity. Deliverable C was impossible to even initiate without Deliverable B complete. 5. Optionally, decreasing the line width of the laser further. This could be done by designing a new cavity to produce a more sensitive error signal and then adjusting the elements which rely on the cavity to control the laser‟s line width so that they can accept the new signal. Obviously, this deliverable was not reached by the 479 team. All of the components for the project, other than the titanium-sapphire ring laser, will need to be purchased by the ENPH 479 group from outside vendors. The group will rely on the budget of the sponsor‟s (Dr Kirk Madison) lab.

description: Finding optimal wave sampling methods has far-reaching implications in wave physics, such as seismology, acoustics, and telecommunications. A key challenge is surpassing the Whittaker-Nyquist-Shannon (WNS) aliasing limit, establishing a frequency below which the signal cannot be faithfully reconstructed. However, the WNS limit applies only to periodic sampling, opening the door to bypass aliasing by aperiodic sampling. In this work, we investigate the efficiency of a recently discovered family of aperiodic monotile tilings, the Hat family, in overcoming the aliasing limit when spatially sampling a wavefield. By analyzing their spectral properties, we show that monotile aperiodic seismic (MAS) arrays, based on a subset of the Hat tiling family, are efficient in surpassing the WNS sampling limit. Our investigation leads us to propose MAS arrays as a novel design principle for seismic arrays. We show that MAS arrays can outperform regular and other aperiodic arrays in realistic beamforming scenarios using single and distributed sources, including station-position noise. While current seismic arrays optimize beamforming or imaging applications using spiral or regular arrays, MAS arrays can accommodate both, as they share properties with both periodic and aperiodic arrays. More generally, our work suggests that aperiodic monotiles can be an efficient design principle in various fields requiring wave sampling.

description: Laser spectroscopy and interferometry have provided an unparalleled view into the fundamental nature of matter and the universe through ultra-precise measurements of atomic transition frequencies and gravitational waves. Optical frequency combs have expanded metrology capabilities by phase-coherently bridging radio frequency and optical domains to enable traceable high-resolution spectroscopy across bandwidths greater than hundreds of terahertz. However, quantum mechanics limits the measurement precision achievable with laser frequency combs and traditional laser sources, ultimately impacting fundamental interferometry and spectroscopy. Squeezing the distribution of quantum noise to enhance measurement precision of either the amplitude or phase quadrature of an optical field leads to significant measurement improvements with continuous wave lasers. In this work, we generate bright amplitude-squeezed frequency comb light and apply it to molecular spectroscopy using interferometry that leverages the high-speed and broad spectral coverage of the dual-comb technique. Using the Kerr effect in nonlinear optical fiber, the amplitude quadrature of a frequency comb centered at 1560 nm is squeezed by >3 dB over a 2.5 THz of bandwidth that includes 2500 comb teeth spaced by 1 GHz. Interferometry with a second coherent state frequency comb yields mode-resolved spectroscopy of hydrogen sulfide gas with a signal-to-noise ratio (SNR) nearly 3 dB beyond the shot noise limit, taking full metrological advantage of the amplitude squeezing when the electrical noise floor is considered. The quantum noise reduction leads to a two-fold quantum speedup in the determination of gas concentration, with impact for fast, broadband, and high SNR ratio measurements of multiple species in dynamic chemical environments.

Plastic filament extrusion system for use with a 3D printer
Creators: name: Eldridge, Dale

Publisher: name: The University of British Columbia
Year: 2012

description: The objective of this project was to produce plastic filament suitable for use with RepRap 3D printers from raw plastic pellets or recycled plastic waste for the UBC Rapid student team. The specifications for the filament required that it be of similar quality to commercial filaments, smooth and with minimal bubbles with a constant diameter of about 3mm. To accomplish this end, a prototype plastic extruder was designed, constructed and tested. The prototype was tested running at different speeds and temperatures to determine a good operating point. The investigation showed that extrusion of plastic filament of comparable quality to commercial filaments is possible with careful operation. The diameter is the most critical feature and is dependent on the rate at which the filament is drawn away from the die as well as a steady input to the heating pipe. With an outfeed mechanism, the filament could be drawn at constant rate to form a constant diameter. The prototype showed several ways in which extrusion could be made more efficient in later designs. The recommendations leading from the testing of the prototype include isolation of the hopper from the heating area to prevent clogging by partially melted plastic and lengthening the heating area to allow for full melting of the plastic and steady flow to extrude for homogeneous filaments.

title: Image-based and structure-integrated sensor for multiaxial measurement of structure deformations
Creators: name: Al-Baradoni, Nassr Mohammed Mosleh
Publisher: name: UNSPECIFIED
Year: 2024

description: Automated process chains in Industry 4.0 lead to increasing relevance for data acquisition to control forces and torques in many manufacturing processes. By measuring process forces and moments, it is possible to implement control approaches and, thus, more accurately obtain selected product characteristics. Moreover, the use of sensors is increasing to enable digital structural monitoring approaches and predictive maintenance. However, poor accessibility, error-prone measurement positions, or harsh environments typically prevent the use of external sensors for the accurate measurement of load conditions in load-bearing structures or process forces/moments in manufacturing machines. Structure and machine elements with integrated sensors permit the direct measurement of process forces and moments on the structural components or machine tools without affecting their mechanical functionality. According to the latest research, the integration of electromechanical transducers, such as strain gauge-based or piezoelectric transducers, into passive metallic structures by various methods, especially forming technology, has proven to be particularly promising. However, while these solutions have excellent potential, their widespread implementation is hampered by the limited performance of the sensors, such as high-resolution detection of the direction and magnitude of the applied loads, and their associated high cost.
This dissertation undertakes an investigation into the viability of employing optical image-based measurement concepts for measuring structural deformation under external loads, with the aim of realizing cost-effective and, at the same time, multiaxial sensor load-bearing structures and machine elements. A specialized measurement concept is developed, and relevant system design parameters are identified in a systematic manner. In addition, a process design is investigated for the integration of sensitive optical elements into metallic structures by rotary swaging, taking into consideration the respective requirements for positional accuracy. The dissertation concludes by highlighting the overall potential of optical image-based sensors for the comprehensive detection of multiaxial loads in structures and machine elements, thereby paving the way for the widespread integration of sensor structures and machine elements in various application domains.
A 400MHz Direct Digital Synthesizer with the AD9912 : Part I : design and fabrication of the device

Publisher: name: The University of British Columbia
Year: 2012

description: Part I of this report discusses the design and and fabrication stage of this project. At time of writing, testing is on hold while a complete prototype device has been assembled. Part II will follow and will include documentation the testing procedures, the results and all recommendations. This project aimed to design, build and test a complete and functional Direct Digital Synthesizer (DDS) device with output frequencies of up to 400MHz. A DDS is a device capable of digitally generating sinusoidal waves with programmable frequency and phase. The Analog Devices 9912 (AD9912) was chosen as a suitable DDS Integrated Circuit (IC) and this was used in the project design. An enclosure also had to be built to house the DDS device. The device had to be compatible with an existing parallel control interface used in the lab, requiring a parallel-to-serial converter, as the AD9912 requires a serial interface. This parallel-to-serial converter was designed and prototyped on a breadboard to verify correct operation. It was also necessary for the device to minimize noise. This was accomplished with a passive analog filter circuit that was simulated in SPICE and confirmed to meet design specifications. Complete designs and fabrication files for the circuit and enclosure had to be provided. The schematics for the board were completed and a PCB layout was designed from this schematic. The PCB layout generated all files required for manufacturing. The enclosure was modifed from an existing design to better accommodate the PCB layout and to improve heat dissipation. Twenty PCBs had to be manufactured and parts had to be ordered for 15 boards. These have all arrived and a prototype device is currently being assembled. Enclosures for 15 boards also had to be ordered and these are all currently being manufactured.

description: Die angestrebten Klimaziele der Europäischen Union erfordern eine Abkehr von den bestehenden, etablierten konventionellen Antrieben hin zu Antrieben auf Grundlage emissionsärmerer Kraftstoffe. Eine vielversprechende Alternative stellt der Einsatz von Erdgas dar. In verflüssigter Form (LNG – Liquefied Natural Gas) besitzt es neben den bekannten Vorteilen hinsichtlich der emittierten Abgase eine ausreichend hohe Energiedichte, um auch im Fernverkehr oder für den Betrieb von mobilen Maschinen Verwendung zu finden. Der Einsatz solcher mobilen Maschinen mit dem Kraftstoff Erdgas wurde im Zuge des Forschungsprojektes LeanDeR untersucht. Dazu wurden sowohl Messungen zur Fahrzeugnutzung als auch zum Emissionsausstoß erhoben. Es wurde ein LNG-betriebener Terminaltraktor einer vergleichbaren dieselbetriebenen Variante gegenübergestellt. Ebenso wurde ein Fahrzeug des Typs Reachstacker auf einen Diesel/LNG-Dual-Fuel-Betrieb umgerüstet und der Betrieb des Fahrzeugs sowohl im reinen Diesel- als auch im Dual-Fuel-Betrieb untersucht. Im Zuge dieses Umweltberichtes werden die Ergebnisse der Emissionsmessung präsentiert und diskutiert. Dabei werden der Versuchsaufbau und die gewonnene Datenbasis beschrieben.
description: The climate targets of the European Union require a move away from the existing, established conventional drives towards drives based on lower-emission fuels. The use of natural gas is a promising alternative. In liquefied form (LNG – Liquefied Natural Gas) it has, in addition to the known advantages in terms of emitted exhaust gases, a sufficiently high energy density for use in long-distance transport or for the operation of mobile machines. The use of such mobile machines with natural gas was being investigated in the course of the research project LeanDeR. For this purpose, both measurements for vehicle use and emissions were collected. A LNG-powered terminal tractor was compared to a comparable diesel operated variant. Likewise, a Reachstacker vehicle was being converted to diesel/LNG-dual-fuel operation and the operation of the vehicle was being investigated in both operation modes. In the course of this environmental report, the results of the emission measurement are presented and discussed. The test setup and the database obtained are also described.

description: In the age of gravitational-wave (GW) sources and newly discovered local black holes (BH) and neutron stars (NS), understanding the fate of stars is a key question. Not every massive star is expected to successfully explode as a supernova and leave behind a NS; some stars form BHs. The remnant depends on explosion physics but also on the final core structure, often summarized by the compactness parameter or iron core mass, where high values have been linked to BH formation. Several groups have reported similar patterns in these parameters as a function of mass, characterized by a prominent compactness peak followed by another peak at higher masses, pointing to a common underlying physical mechanism. Here, we investigate its origin by computing single-star models from 17 to 50 solar masses with MESA. The first and second compactness increases originate from core carbon and neon burning, respectively, becoming neutrino dominated, which enhances the core contraction and ultimately increases the iron-core mass and compactness. An early core neon ignition during carbon burning, and an early silicon ignition during oxygen burning help counter the core contraction and decrease the final iron core mass and compactness. Shell mergers between C/Ne and O-burning shells further decrease the compactness and we show that they are due to an enhanced entropy production in these layers. We find that the final structure of massive stars is not random but already written in their cores at core helium exhaustion. The same mechanisms determine the final structure of any star in this core mass range, including binary products, though binary interactions systematical shift the range of expected BH formation. Finally, we discuss the role of stellar physics uncertainties and how to apply these findings to studies of GW sources. [Abridged]

description: Social media platforms enable instant and ubiquitous connectivity and are essential to social interaction and communication in our technological society. Apart from its advantages, these platforms have given rise to negative behaviors in the online community, the so-called cyberbullying. Despite the many works involving generative Artificial Intelligence (AI) in the literature lately, there remain opportunities to study its performance apart from zero/few-shot learning strategies. Accordingly, we propose an innovative and real-time solution for cyberbullying detection that leverages stream-based Machine Learning (ML) models able to process the incoming samples incrementally and Large Language Models (LLMS) for feature engineering to address the evolving nature of abusive and hate speech online. An explainability dashboard is provided to promote the system's trustworthiness, reliability, and accountability. Results on experimental data report promising performance close to 90 % in all evaluation metrics and surpassing those obtained by competing works in the literature. Ultimately, our proposal contributes to the safety of online communities by timely detecting abusive behavior to prevent long-lasting harassment and reduce the negative consequences in society.

LeanDeR ist ein Verbundvorhaben zwischen den Industriepartnern Duisburger Hafen AG und RWE Supply & Trading (RWEST GmbH) sowie einem Partner der Wissenschaft, der Universität Duisburg Essen (UDE). In dem Verbundvorhaben LeanDeR wird ein ganzheitliches und nachhaltiges LNG-Logistikkonzept über mehrere Planungsstufen entwickelt und im Duisburger Hafen unter Praxisbedingungen im Demonstrationsbetrieb getestet und evaluiert. Das Projekt legt mit seinem multimodalen Konzept den Grundstein für eine nachhaltige Mobilität an dem Leuchtturmstandort Duisburger Hafen. Der Projektkern ist der Betrieb einer multimodal nutzbaren mobilen LNG-Anlage sowie die forschungsseitig begleitete Umrüstung und Demonstration zweier Hafenumschlagsgeräte. In dem Demonstrationsvorhaben wird ein starker Fokus auf die Forschung und Entwicklung der LNG-Technologie gelegt, was den Wissens-stand zum Einsatz von LNG in der Industrie dauerhaft erhöhen soll. In diesem Zusammenhang wird der Test-betrieb von Hafenumschlaggeräten unter realen Bedingungen durchgeführt. Die Geräte werden im Dual-Fuel-(Diesel/LNG) sowie im reinen LNG-Betrieb erforscht, getestet und optimiert. Die gewonnenen Ergebnisse wer-den zur Entwicklung eines langfristigen Geschäftsmodells für die LNG-Kraftstoff-Nutzung verwertet und verbreitet. Das Arbeitspaket 4 (AP4), dessen Ergebnisse anteilig im vorliegenden Bericht dargestellt werden, fokussiert sich auf die Erarbeitung von Leitfäden, Handlungsanweisungen, ggf. Normen und den regulatorischen Rah-men für den Einsatz von LNG in dem genannten Kontext. Dieses AP stellt den technischen und normativen Wissenstransfer über die Projektgrenzen hinaus sicher. Ein wesentliches Ergebnis dieses Arbeitspaketes ist dieser Leitfaden zum Betrieb und zur Betankung von Hafengeräten durch eine mobile LNG-Anlage sowie zum LNG-Betrieb von Hafenfahrzeugen.

Recommendation report : apparatus to amplify headphones and test sound quality
Creators: name: Ellis, George
Publisher: name: The University of British Columbia

description: The purpose of this project was to prototype a hi-quality headphone amplifier, and to measure the amp’s performance using a dummy (pure resistive) or real headphone load. The idea was to either demonstrate how a headphone amp could quantifiably improve sound quality played out of a source, or to at least investigate typical usage scenarios and metrics for measuring sound quality. Key metrics identified for characterising the amp’s performance were: input and output impedance, signal-to-noise + distortion (SINAD), and the gain response over audio frequencies. The original discrete amplifier design chosen for the project was changed a more forgiving LM1875 op amp design during the prototyping stage due to deficiencies in parts ordered. The second amp was measured to have 21 Ω input and < 1 Ω output impedances, and a noise floor at -85 dB(VRMS) relative to the audio signal. Qualitatively, the amplifier was able to drive audio transducers from computer Line Out with impedances from 8 Ω to 100 Ω without noticeable noise or degrading audio quality. It was concluded that a medium-quality audio amplifier is not necessarily suitable for all applications. Recommendations include further testing and continued prototyping of the more ambitious (but trickier) hi-fi design.

description: Cybersecurity requires an effective risk transfer regime and a well‐functioning insurance market to improve stakeholder resilience. However, rapid cyber threat adaptation, limited data availability, and inadequate risk understanding pose significant challenges for the insurance industry and its customers. This research uses a mixed methods approach to analyze the inclusions, exclusions, and suitability of current cyber policies in the German cyber insurance market. The study analyzes 41 cyber insurance policies, representing about 80% of the German cyber insurance market. This examination is supported by semistructured interviews with 23 cyber insurance experts. The authors find that there are no standardized cyber policy wordings, and insurers use different terms and definitions in their insurance policies. Specifically, the results show a significant lack of clarity around coverages and exclusions. This research contributes to the cybersecurity risk management community and will enable businesses, insurance companies, and policymakers to better understand, measure, and manage cyber risk.
Phase-Synchronized Quantum Energy Transfer: Resolving the Long-Distance Transfer Paradox through Synchromatics Theory
Creators: name: Fedotov, Anton
Publisher: name: Zenodo
Year: 2024

description: This work delves into the mechanics of quantum energy transfer via phase resonance fields, presenting a fresh perspective on long-distance energy exchange between quantum systems without the need for entanglement or particle exchange. By applying the Synchromatics framework, we address the "long-distance transfer paradox" — the puzzling observation that certain quantum interactions appear to maintain coherence over significant separations, defying traditional limitations imposed by decoherence and attenuation in quantum mechanics.

Synchromatics introduces phase synchronization as a bridge to explain these paradoxical behaviors, offering mathematical models and specific predictions. These include resonance amplification in variable-density media, energy transfer through phase tunnels in vacuum, and phase correction effects in gravitationally perturbed fields. Experimental pathways are also suggested, aiming to validate Synchromatics' applicability across fields such as quantum information, biophysics, and astrophysics. This study invites further investigation into how resonance fields might reshape our understanding of quantum coherence and non-local interactions.

title: Responding to Disclosure: A Study to Explore the Preparation of Trainee Teachers to Operationalise Safeguarding Policy in the Context of Adolescent Sexting Behaviour
Creators: name: Hewitson, Dawn Sylmay
Publisher: name: University of Central Lancashire
Year: 2024

description: This professional doctorate explores the content and efficacy of safeguarding training for secondary computer science trainee teachers, referred to as trainees or computing teachers. The research focuses on the preparation of trainees to operationalise safeguarding policy in the context of disclosures of online Aggressive Adolescent Sexting Behaviours (AASB) in secondary schools located in North-West England. The researcher studies key stakeholders and trainees, seeking to answer three research questions: How do trainees define sexting behaviours? How should trainee teachers plan to respond to AASB? How do trainees plan to respond to AASB? This study uses Kincheloe and Berry’s (2004) conceptualisation of Bricolage methodology and Quinlan and Cross’s (2020) adaptation of Papert’s (1993) Computational Thinking (CT) that informed the theoretical and conceptual framework to structure this research investigation. Lipsky’s (1980) ‘Street Level Bureaucracy’ was applied to explore simulated trainee policy enactment. This research uses three methods to elicit data:

• Vignettes containing sexting incidents derived from Wolak and Finkelhor’s (2011) study, ‘Sexting a Typology’, combine vignettes with trainee participant surveys.
• A trainee focus group.
• Semi-structured interviews with participant experts. Text-based thematic analysis identifies emergent themes using Braun and Clarke’s (2022) thematic analysis.

Preliminary findings indicate a trainee knowledge gap regarding constructing comprehensive definitions of sexting behaviours and identifying the constituents of AASB. Trainees expressed apprehension concerning encountering AASB pupil disclosures in schools and discussed limited exposure to training and support. Practitioner experts and consultants state that trainees should know who school safeguarding officers are and should be able to use school safeguarding reporting systems confidently. Furthermore, practitioner and consultant experts expect trainees to possess skillsets that support and reassure AASB victims and specifically know how to help and direct pupils regarding removing imagery from the Internet. The Office for Standards in Education (OFSTED, 2021b) identifies the need to address sexually aggressive behaviour in schools. Therefore, the recommendations here stress the need for trainees to experience consistent AASB training. Further findings indicate that current training resources to address AASB and cyberbullying behaviours in schools are inadequate for novice teachers, and this study recommends updating these resources.

description: We present a numerical discovery that the observable stellar properties of present galaxies retain significant dependences on the primordial density and tidal fields. Analyzing the galaxy catalogs from the TNG300-1 simulations, we first compute the primordial spin factor, $τ$, defined as the mean degree of misalignments between the principal axes of the initial density and potential hessian tensors at the protogalactic sites. Then, we explore in the framework of Shannon's information theory if and how strongly each of six stellar properties of the present galaxies, namely two stellar sizes ($R_{90\star}$ and $R_{50\star}$), ages, specific star formation rates, optical colors and metallicities, share mutual information with $τ$, measured at $z=127$. Deliberately controlling the TNG galaxy samples to have no differences in the mass, environmental density and shear distributions, we single out net effects of $τ$ on each of the galaxy stellar properties. In the higher stellar mass range of $M_{\star}/(h^{-1}\,M_{\odot})\ge 10^{10}$, significant amounts of mutual information with $τ$ are exhibited by all of the six stellar properties, while in the lower range of $M_{\star}/(h^{-1}\,M_{\odot})< 10^{10}$ only four of the six properties except for the specific star formation rates and colors yield significant signals of $τ$-dependence. Examining how the mean values of the six stellar properties vary with $τ$, we also show that the galaxies originated from the protogalactic sites with higher $τ$ values tend to have larger sizes, later formation epochs, higher specific star formation rates, bluer colors and lower metallicities. It is also discovered that the galaxy stellar sizes, which turn out to be most robustly dependent on $τ$ regardless of $M_{\star}$, follow a bimodal Gamma distribution, the physical implication of which is discussed.

description: Rodents have become a problem in a older greenhouse at the UBC Farm. They find the warm atmosphere of the greenhouse and the harvest and seedlings stored in the greenhouse a welcoming home. The rodents damage the hard work of the UBC Farm staff. Conventional rodent control mechanism have proven ineffective such as sonic traps which use high frequency ultrasound; snap traps require a great deal of attention and attract birds into the greenhouse when rodents are caught; resealing the greenhouse is far too costly; thus, the our team has designed an active device to track rodent movement within the bounds of the greenhouse and follow the rodents with the ability to trigger an external device for frightening the rodents. The external devices is out of the scope of our engineering team’s knowledge and is left up to professionals in the field to implement. We present a real-­‐time image-­‐processing mechatronic system. Using an infrared camera, to eliminate the distinction between daylight and night time, to capture images of the greenhouse and using image processing on the computer track rodents. The device installed in the greenhouse includes a housing mechanism for the camera with motors to control the position of the camera and consequently any external triggering device attached to it. The tracking system is tested in the laboratory and has proven effective at tacking small objects in both regular light and low light conditions. There is a ~1.5s delay in motion present in front of the camera and reaction of the tracker; however, in the time frame present our team was not able to eliminate this delay completely but reduced it down from 2.8s to 1.5s using sophisticated probabilistic models for immediate future motion tracking. The system has 5 components, 3 of which are coded on a computer using MATLAB computation software while the other 2 components are an Arduino microcontroller and the infrared camera. The computer and microcontroller communicate via a serial connection while information from the camera is read into the computer via Ethernet. Accurate and precise motion detection allows the system to detect the smallest of changes in the environment it is monitoring thus making the system ideal for small rodents.
