title: Enhancing the Efficiency of Subject-Specific Knee Joint Biomechanical Simulations With Applications to Osteoarthritis
Creators: name: Kakavand, Reza
Publisher: name: Graduate Studies
Year: 2024
Subjects: subject: Engineering--Mechanical
subject: Engineering--Biomedical

description: There are three challenges in conventional subject-specific modelling techniques. First, having an accurate material model is essential for studying biomechanical response of musculoskeletal systems. For instance, the stresses and strains in knee joint articular cartilage are influenced by site-specific variations in collagen fibril orientations that vary with aging, which is ignored in finite element (FE) analyses using a generic knee geometry. The other challenge is related to the manual geometry reconstruction from biomedical images, which is a time-consuming process and not practical for clinical applications. Finally, estimating joint forces and moments with conventional methods requires marker-based motion capture facilities to study the kinematics of human body motion and convoluted human body modeling to determine the kinetics of motions. Although marker-based motion capture offers the precise measurement of marker positions on the body and enables the calculation of kinematics and kinetics in a controlled setting, its data collection is labor-intensive and requires staff with expensive equipment and specialized technical experience. Subject-specific FE modeling provides a viable approach for the study of cartilage mechanics in normal and pathomorphological knee, thus providing insight into the mechanics of knee articular cartilage. Therefore, in this project we aimed to facilitate the development of subject-specific FE models of the knee. We developed and validated: 1) a 3D remodeling algorithm of collagen fibrils within knee joint cartilage under simulated gait, 2) a semi-automatic segmentation routine of knee joint geometry from magnetic resonance images (MRIs), and 3) a markerless motion capture to perform kinematics and kinetics analyses. To develop the cartilage fibril remodeling algorithm, a fibril-reinforced, biphasic cartilage model was integrated with 3D human knee joint geometry. For the MRI segmentation, we used 3D Swin UNETR, a statistical shape model (SSM) and automated filtering techniques to extract the distal femur, proximal tibia, femoral and tibial cartilages. To facilitate the estimation of joint forces and moments, OpenCap, a markerless motion capture software, was used during a cycling task. This technique is intended to expedite kinematics and kinetics analysis. The ultimate goal of this project is to develop an efficient pipeline for subject-specific FE modeling.

description: The 1st workshop of the series, ‘Why Mappings Matter and how to make them FAIR?" was organised on April 13th by FAIR-IMPACT and the SSSOM developer community. to introduce participants to the motivation behind doing mappings and how they could benefit even more by making mappings FAIR. A series of Show and Tell presentations took place, where use cases and practices from a range of communities –spanning domains, research infrastructures, projects, task forces, and working groups– were presented. During this workshop, the Simple Standard for Sharing Ontological Mappings (SSSOM) was introdeuced as a candidate format for defining and sharing entity mappings, considering also its pivotal role in the FAIRCORE4EOSC technical specifications. The presentations was followed by a collaborative work on mapping aspects, including methodologies, formats, tools, requirements for FAIR mappings and examples. The main objective of this workshop was to define, together with different communities, the initial requirements for developing a useful framework around FAIR mappings including the requirements to adhere to the FAIR principles.

description: When patients have strong initial attitudes about a medical intervention, they might not be open to learning new information when choosing whether or not to receive the intervention. We aim to show that non-fit messaging (messages framed in a manner that is incongruent with recipients’ motivational orientation) can increase attention to the message content, thereby de-intensifying an initial attitude bias and reducing the influence of this bias on choice. In this study, 196 students received information about the pros and cons of a vaccine, framed in either a fit or non-fit manner with their motivational orientation. The results show that when information was presented in a non-fit (vs. fit) manner, the strength of participants’ initial attitude was reduced. An eye-tracking procedure indicated that participants read information more thoroughly (measured by the average length of fixation time while reading) in the non-fit condition versus fit condition. This average time of fixation mediated the effect of message framing on the strength of people’s attitudes. A reduction in attitude was associated with participants’ ability to recall the given information correctly and make a choice consistent with the provided information. Non-fit messaging increases individuals’ willingness to process information when individuals’ pre-existing attitude biases might otherwise cause them to make uninformed decisions.
Optimal nonlocal multipartite entanglement concentration based on projection measurements

description: We propose an optimal nonlocal entanglement concentration protocol (ECP) for multi-photon systems in a partially entangled pure state, resorting to the projection measurement on an additional photon. One party in quantum communication first performs a parity-check measurement on her photon in an N-photon system and an additional photon, and then she projects the additional photon into an orthogonal Hilbert space for dividing the original $N$-photon systems into two groups. In the first group, the N parties will obtain a subset of $N$-photon systems in a maximally entangled state. In the second group, they will obtain some less-entangled N-photon systems which are the resource for the entanglement concentration in the next round. By iterating the entanglement concentration process several times, the present ECP has the maximal success probability which is just equivalent to the entanglement of the partially entangled state. That is, this ECP is an optimal one.

description: Art and science are essential for sustainable development, and art-science interactions can advance both fields and enhance their impact. This is supported by historical, personal, and contemporary examples. Dance and performing arts are especially powerful when representing the physical world studied by environmental science, and for encouraging change in thoughts and actions related to the environment. The ways in which artistic approaches differ from the scientific are helpful in encouraging innovation and scientific discovery. Obstacles to such collaborations are discussed, as well as potential solutions and best practices. One such practice is measuring impacts of interdisciplinary collaborations, and a methodology is proposed to do so. Study of these interactions will enable strategic art-science partnerships and encourage wider acceptance of interdisciplinary innovation.
Spectrum sensing and throughput maximization in cognitive radio networks
Creators: name: Moghimi, Farzad
Publisher: name: University of British Columbia
Year: 2012

description: In cognitive radio (CR) systems, reliable spectrum sensing techniques are required in order to avoid interference to the primary users (PUs) of the spectrum. In this dissertation two spectrum sensing techniques are developed, and sensing time and power allocation are optimized in multi-input multi-output (MIMO) CR systems. The motivation of the first proposed spectrum sensing technique is that, in practice, CRs also have to cope with various types of non-Gaussian noise such as man-made impulsive noise, and co-channel interference. However, most of the existing literature on spectrum sensing only considers impairment by additive white Gaussian noise (AWGN). To address this issue, we propose an Lp-norm detector which has tunable parameters that can be adjusted for the underlying type of noise. We also propose an adaptive algorithm for optimization of the Lp-norm parameters which does not require any a priori knowledge of the noise statistics. The motivation for the second proposed spectrum sensing technique is that the signals transmitted by PUs often also contain known pilot symbols for synchronization and channel estimation purposes. Coherent correlation based spectrum sensing techniques can exploit these known symbols but waste the energy contained in the data symbols. Hence, while considering AWGN impairment, we propose a hybrid coherent/energy detection scheme which exploits both the pilot and the data symbols transmitted by the PU. Since the complexity of the globally optimal hybrid detection metric is very high, we develop a simple locally optimal hybrid metric, which turns out to be a linear combination of an energy detection metric and a correlation metric. While the proposed methods improve the accuracy of spectrum sensing, there exists a tradeoff between sensing time and transmission time for CR networks. In this thesis, we investigate this issue for conventional energy detection in MIMO CR networks. Specifically, we optimize the sensing threshold, sensing time, and transmit power of both single-band and multi-band MIMO CR systems for maximization of the opportunistic throughput under transmit power, probability of false alarm, and probability of detection constraints. We also develop efficient iterative algorithms for solving these non-convex optimization problems based on the concept of alternating optimization.
Magnetic interactions in iron superconductors studied with a five-orbital model within the Hartree-Fock and Heisenberg approximations

description: We have analyzed the magnetic interactions of a five orbital model for iron superconductors treated both within Hartree-Fock and Heisenberg approximations. We have found that the exchange constants depend non-trivially on the Fe-As-Fe angle and on the charge and orbital filling. Within the localized picture, columnar ordering is found for intermediate Hund's coupling J_H. At smaller J_H, an unusual orbital reorganization stabilizes checkerboard ordering. Ferromagnetism appears at large J_H. Ferromagnetic correlations are enhanced with electron doping while large hole doping stabilizes checkerboard antiferromagnetism, explaining the change in magnetic interactions upon substitution of Fe by Co or Mn. For intermediate and large values of U, Hartree-Fock shows similar results as strong coupling though with a double stripe phase instead of ferromagnetism. Itinerancy enhances the stability of the columnar ordering. Comparison of the two approaches reveals a metallic region of the phase diagram where strong coupling physics is determinant.

description: In this master’s thesis, I explore how community gardening contributes to place-making and belonging among newcomer youth of colour. While existing research largely focuses on community gardening with newcomer adults and their ways of creating home during migration, there's a notable gap concerning newcomer youth's place-making practices. This research addresses this gap by employing feminist qualitative research methods with a co-design methodology in the centre; collaborating with 18 newcomer youth of colour within a community-based research initiative, we co-created a community garden (YARI-Collective, 2024). The co-design methodology draws on critical Southern feminist axiological orientations toward deep care (Banerjee, Khandelwal, & Sanyal, 2022) and a Southern moral imaginary (Banerjee, Chacko, & Korsha, 2022). This approach resists the marginalization of newcomer youth gardeners by centering their voices in garden design decisions and within a historical context of colonialism that implicates host countries of global north in their displacement. Attending to the politically and experientially contested nature of newcomer community gardens (Strunk & Richardson, 2019; Tsu, 2021), I found that home and a sense of belonging among newcomer youth of colour emerged in the co-designed garden in four key ways. First, in centering stories of home, a collaborative approach to knowledge production that subverted neoliberal and paternalistic models of newcomer ‘deficiency’ emerged in the garden. Second, a sense of community emerged in the garden through the multiplicity of the space as engendered through re-embodying parts of home and practices of community that have been discouraged elsewhere in Canada. Third, embodied and sensorial connections to land facilitated the surfacing of memories and ways of being from home that resist the erasure of newcomer youth of colour’s subjectivities, as well as the erasure and fragmentation of land as an object of colonial dispossession. Finally, the public engagements around the garden amplified the unsilencing of newcomer youth gardeners’ voices beyond the immediate community of the research collective. In conclusion, this thesis critiques neoliberal and colonial views of newcomer gardening and integration as linear and individualistic, following instead the re-orientations offered by newcomer youth gardeners toward collective care and dignity.

description: We present an analysis of the evolution of the central mass-density profile of massive elliptical galaxies from the SLACS and BELLS strong gravitational lens samples over the redshift interval z ~ 0.1-0.6, based on the combination of strong-lensing aperture mass and stellar velocity-dispersion constraints. We find a significant trend towards steeper mass profiles (parameterized by the power-law density model with rho ~ r^[-gamma]) at later cosmic times, with magnitude d/dz = -0.60 +/- 0.15. We show that the combined lens-galaxy sample is consistent with a non-evolving distribution of stellar velocity dispersions. Considering possible additional dependence of on lens-galaxy stellar mass, effective radius, and Sersic index, we find marginal evidence for shallower mass profiles at higher masses and larger sizes, but with a significance that is sub-dominant to the redshift dependence. Using the results of published Monte Carlo simulations of spectroscopic lens surveys, we verify that our mass-profile evolution result cannot be explained by lensing selection biases as a function of redshift. Interpreted as a true evolutionary signal, our result suggests that major dry mergers involving off-axis trajectories play a significant role in the evolution of the average mass-density structure of massive early-type galaxies over the past 6 Gyr. We also consider an alternative non-evolutionary hypothesis based on variations in the strong-lensing measurement aperture with redshift, which would imply the detection of an "inflection zone" marking the transition between the baryon-dominated and dark-matter halo-dominated regions of the lens galaxies. Further observations of the combined SLACS+BELLS sample can constrain this picture more precisely, and enable a more detailed investigation of the multivariate dependences of galaxy mass structure across cosmic time.

description: In the Amazonian department of Caquetá (Colombia), considered a Revolutionary Armed Forces of Colombia (FARC) stronghold, 300 families are currently challenged with implementing the peace agreement in their territory while also navigating the road to sustainable development. This process entails trusting others, collaborating, and making decisions about health and education services, environmental problems, economic issues, and even aspects of everyday life. The Paisajes Conectados program is focused on reducing deforestation and promoting sustainable development in two municipalities of Caquetá. Its mission is to build new skills and share knowledge within local communities in order to strengthen governance and participation. This paper presents the findings of a field practicum, developed with the objective of determining community perceptions of the Capacity Building and Governance Strategy implemented under the Paisajes Conectados program in the context of a transition from conflict to peace.
title: A Novel Data Science Approach to Estimate a Borehole Caliper Log Utilizing Tripping Data
Creators: name: Prasad, Mandyam Rangayyan Prathik
Publisher: name: Graduate Studies
Year: 2024
Subjects: subject: Engineering--Chemical

description: During drilling operations, monitoring the borehole integrity is crucial. Borehole irregularities, such as constrictions, ledges, and breakouts, can lead to significant non-productive time and present challenges when casing and cementing the well, adversely affecting operational efficiency. These issues are particularly problematic during tripping – the process of moving the drill string in and out of the borehole. However, monitoring rig data during trips presents an opportunity to monitor the same problems. Early identification of such dysfunctions allows proactive measures to mitigate their impact on operations. This technique shows promise for estimating borehole quality in advance of wireline caliper measurements while also allowing for deeper estimation in geothermal wells where current caliper tools cannot log due to high temperatures. This study introduces a novel forward/backward modelling strategy that utilizes resistance signatures in conjunction with drill string configurations to identify and quantify borehole dysfunctions, thereby enhancing operational efficiency. This approach is based on the analysis of overpull, calculated by subtracting the expected hook load (HL) calculated from a soft string drill string model from the real-time measurements of HL. Two signals were used for analysis: the Bottom Hole Assembly (BHA) configuration signal and a synthetic resistance signal. The BHA signal represents the outer diameter (OD) of the BHA, whereas the synthetic resistance signal represents the borehole gauge vs. depth. A synthetic overpull signal can be obtained by convolving the BHA signal with the resistance profile at each depth. In the reverse problem, the real overpull signal may be deconvolved with the BHA signal to estimate the resistance signal. The model was applied to actual overpull data from a drilling operation. First, the resistance signal was manually estimated to enable the overpull signal to match the field data. There was a good match between the resistance signal and the measured four-arm caliper log. A backward model was then applied to calculate the resistance signal. For shallow depths, the model is capable of detecting changes in the caliper log; however, for deeper depths, drill string dynamics confound the signal, presenting an opportunity to perform further work.
Restoration of Lorentz Symmetry for Lifshitz-Type Scalar Theory

description: The purpose of this paper is to present our study on the restoration of the Lorentz symmetry for a Lifshitz-type scalar theory in the infrared region by using nonperturbative methods. We apply the Wegner-Houghton equation, which is one of the exact renormalization group equations, to the Lifshitz-type theory. Analyzing the equation for a z=2, d=3+1 Lifshitz-type scalar model, and using some variable transformations, we found that broken symmetry terms vanish in the infrared region. This shows that the Lifshitz-type scalar model dynamically restores the Lorentz symmetry at low energy. Our result provides a definition of ultraviolet complete renormalizable scalar field theories. These theories can have nontrivial interaction terms of ϕ^{n} (n=4, 6, 8, 10) even when the Lorentz symmetry is restored at low energy.

description: A small proportion of children and youth undergo grief over losing a parent, sibling, or another family member. Although parentally bereaved children comprise a low-incident, vulnerable population, they are at risk for developing mental health issues. Given that students spend most of their time in school environments, it is crucial for educational institutions to have mechanisms in place to provide ongoing individual support for bereaved students. School psychologists are well-positioned to offer direct services and consultation tailored to the needs of bereaved students; however, there is limited literature exploring the current level of involvement and training of school psychologists in supporting parentally bereaved children. The purpose of this study is to clarify school psychologists' role and perspectives on supporting parentally bereaved children at the school level. Semi-structured interviews were transcribed and analyzed using reflexive thematic analysis. The following six global themes were identified: (a) what does grief look like, (b) perceived supports and services that are necessary for grieving children, (c) addressing grief in schools: practices, policies, and responses, (d) school psychologists serve as a valuable asset for school communities, (e) barriers to implementation of services and supports, and (f) lifelong learning: continuing to develop and expand knowledge. This study explored the challenges and barriers that school psychologists face in supporting parentally bereaved children and aimed to identify existing strategies and resources that are effective in meeting the needs of bereaved students in school settings.

description: We discuss a class of (local and non-local) theories of gravity that share same properties: i) they admit the Einstein spacetime with arbitrary cosmological constant as a solution; ii) the on-shell action of such a theory vanishes and iii) any (cosmological or black hole) horizon in the Einstein spacetime with a positive cosmological constant does not have a non-trivial entropy. The main focus is made on a recently proposed non-local model. This model has two phases: with a positive cosmological constant $Λ>0$ and with zero $Λ$. The effective gravitational coupling differs essentially in these two phases. Generalizing the previous result of Barvinsky we show that the non-local theory in question is free of ghosts on the background of any Einstein spacetime and that it propagates a standard spin-2 particle. Contrary to the phase with a positive $Λ$, where the entropy vanishes for any type of horizon, in an Einstein spacetime with zero cosmological constant the horizons have the ordinary entropy proportional to the area. We conclude that, somewhat surprisingly, the presence of any, even extremely tiny, positive cosmological constant should be important for the proper resolution of the entropy problem and, possibly, the information puzzle.

The incorporation of acoustic technology into the Canadian Pacific sardine (Sardinops sagax) survey
Creators: name: Graas, Jonathon Allan
Publisher: name: University of British Columbia
Year: 2012

description: Hydroacoustics can provide cost-effective ways of improving the accuracy of non-acoustic surveys, such as Canada’s annual nighttime Pacific sardine (Sardinops sagax) surface trawl survey. Seasonal sardine abundance in Canada is currently estimated by extrapolating average catch densities from this survey to 30 m depth over a distributional area. The primary goal of this thesis was to assess, using acoustic methods, the uncertainty associated with catch density extrapolation from the trawl survey. Nighttime bias in the acoustic data due to the near-field limits was also investigated. An alternative acoustic approach is then reviewed to direct future research. Concurrent acoustic and trawl catch data from the 2011 Canadian sardine survey were analyzed to compare the two methodologies and approximate the species’ vertical distribution within the near-surface layer at night. Acoustic observations made at 38 and 120 kHz were compared to determine if fish are present in the near-field safe range of the 38 kHz transducer. Acoustic observations indicated that sardine density was significantly greater (P<0.05) above the trawl’s foot rope path than below it. Substantial backscatter in the surface scattering layer was observed within the near-field safe range of the 38 kHz transducer. No significant linear relationships between trawl-based density and acoustic backscatter or density estimates were found. These findings have important implications as sources of uncertainty in non-acoustic and acoustic methods were identified, including catch density extrapolation and the near-surface acoustic blind-zone and/or near-field safe range. This thesis then reviews the potential of multi-beam acoustics as an alternative to single-beam. Multi-beam sonars (MBS) can sample the water column over a wide range of angles and near-surface targets can be detected. Present methodologies and hardware, however, cannot yet quantify multi-beam backscatter as abundance. Calibration procedures for MBS’s are undefined for most models. Hardware and software required for real-time interaction with acoustic gear have not been developed for many systems. Since MBS’s insonify targets from multiple angles, the conversion of multi-beam backscatter to abundance is complex. Research on the natural orientation of fish and the accurate averaging of backscatter from multiple incidence angles is needed.

description: Quasiclassical approximation in the intrinsic description of the vortex filament dynamics is discussed. Within this approximation the governing equations are given by elliptic system of quasi-linear PDEs of the first order. Dispersionless Da Rios system and dispersionless Hirota equation are among them. They describe motion of vortex filament with slow varying curvature and torsion without or with axial flow. Gradient catastrophe for governing equations is studied. It is shown that geometrically this catastrophe manifests as a fast oscillation of a filament curve around the rectifying plane which resembles the flutter of airfoils. Analytically it is the elliptic umbilic singularity in the terminology of the catastrophe theory. It is demonstrated that its double scaling regularization is governed by the Painleve' I equation.

description: Intensified acute in-hospital physiotherapy (IP) after hip fracture (HF) may enhance patient’s ability to regain basic mobility at discharge. The primary objective was to assess the feasibility of IP. Secondary to estimate the effect of IP on regained basic mobility at discharge. In a pragmatic, randomized, unblinded feasibility trial, 60 patients (mean age 79 years, 41 women) with HF and an independent pre-fracture basic mobility level were randomized (2:1) to IP with two daily sessions on weekdays focusing on functional training and weight-bearing activities (n = 40) versus usual care (UC) physiotherapy once daily (n = 20). Feasibility outcomes included physiotherapy completion rates, reasons for non-successful completion, and adverse events. The primary effect outcome was recovery of basic mobility (Cumulated Ambulation Score (CAS)). Eighty-two percent of the sessions in the IP group were successfully- or partially completed versus 94% of the sessions in the UC group. No adverse events occurred. The main reason for not completing physiotherapy was fatigue. At discharge (median 7 days), 50% in the IP group had regained their pre-fracture basic mobility level (CAS = 6) versus 16% in the UC group; odds ratio = 5.33, 95%CI [1.3;21.5]. IP seems feasible for patients after HF surgery, and it may enhance recovery. Fatigue was the primary obstacle to completing IP. Two daily physiotherapy sessions focusing on functional training and weight-bearing activities are feasible for patients after isolated hip fracture surgery, including subtrochanteric fracture, and may enhance recovery of basic mobility at discharge.During hospitalization, patient participation in intensified physiotherapy is mainly restricted by fatigue.Systematic assessment and management of fatigue may improve the completion of physiotherapy and recovery of basic mobility.

description: It is recently conjectured that generic non-extremal Kerr black hole could be holographically dual to a hidden conformal field theory in two dimensions. Moreover, it is known that there are two CFT duals (pictures) to describe the charged rotating black holes which correspond to angular momentum $J$ and electric charge $Q$ of the black hole. Furthermore these two pictures can be incorporated by the CFT duals (general picture) that are generated by $SL(2,\mathbb{Z})$ modular group. The general conformal structure can be revealed by looking at charged scalar wave equation in some appropriate values of frequency and charge. In this regard, we consider the wave equation of a charged massless scalar field in background of Kerr-Sen black hole and show in the "near region", the wave equation can be reproduced by the Casimir operator of a local $SL(2,\mathbb{R})_L \times SL(2,\mathbb{R})_R$ hidden conformal symmetry. We can find the exact agreement between macroscopic and microscopic physical quantities like entropy and absorption cross section of scalars for Kerr-Sen black hole. We then find an extension of vector fields that in turn yields an extended local family of $SL(2,\mathbb{R})_L \times SL(2,\mathbb{R})_R$ hidden conformal symmetries, parameterized by one parameter. For some special values of the parameter, we find a copy of $SL(2,\mathbb{R})$ hidden conformal algebra for the charged Gibbons-Maeda-Garfinkle-Horowitz-Strominger black hole in the strong deflection limit.

description: The Philippines is among the countries most threatened by climate change. This combined with other human and developmental factors compounds the challenge that barangays, the smallest political and administrative units in the country, face: to build and scale-up local resilience. This paper presents the case of Barangay Tumana in Marikina City, Philippines, the second most populated barangay in the city and the most devastated when Typhoon Ondoy (international name: Ketsana) hit the country in 2009.

The study examines key hazards and elements of the communities in Barangay Tumana that contribute to its susceptibility to climate-related impacts, using the definition of the United Nations Framework Convention on Climate Change (UNFCCC) to frame the process of analysis. In particular, it characterizes the biophysical/environmental risks and socioeconomic/demographic vulnerabilities of the communities (exposure and sensitivity elements) in Barangay Tumana that can be addressed through planning in order to further community resilience and enhance long-term quality of life (Ensor, and Berger, 2009). These risks and vulnerabilities are established through various quantitative and qualitative methods of data gathering and analysis, including questionnaire surveys, key informant interviews, Geographic Information System (GIS) analysis, reviews of key local documents and related literature, and a multi-stakeholder validation and consultation. Policy options to build barangay resilience in the context of climate change are then recommended.

description: Geothermal energy is a clean, reliable, and domestic source of energy that offers constant electricity while emitting relatively few emissions of carbon dioxide and other pollutants. Despite these benefits, its development globally has not been as rapid in recent years as that of other renewable energy sources. We examine Indonesia as a case study— while home to over a third of the world’s geothermal resources, the country exploits only 5.8% of it. Moreover, as a rapidly developing economy with projected electricity growth of 8.5% per year until 2025, Indonesia must harness its geothermal potential if it is to meet electricity needs without requiring the fossil fuels upon which it has historically been reliant. However, significant roadblocks impede geothermal development in Indonesia, primarily in the geoscientific, financial, and political spheres. Firstly, there is a lack of geologic data crucial to preliminary geothermal potential assessment, rendering it difficult to locate available resources. Financial issues also deter investment in geothermal development by private companies due to the high up-front cost of preliminary resource exploration. Lastly, an uncertain political and regulatory environment create uncertainty for geothermal investors. Cognizant of these problems, we examine solutions and policies effectively implemented by other countries and industries that can be applied to Indonesian geothermal energy development. While specific to Indonesia, our recommendations for collaborations amongst governments, development agencies, and private companies bear implications for accelerating the development of geothermal energy resources worldwide.
title: Development of Asphaltenes-derived Carbon Fiber Reinforced Composite for Structural Applications via 3D Printing

description: There is an increasing demand for carbon fibers (CFs) that are affordable and have outstanding mechanical properties in a wide range of industries. Asphaltenes (i.e., the heavy fraction of bitumen) have recently been identified as promising low-cost precursors for developing low-cost carbon fibers that could accelerate the widespread adoption of CFs in existing and new industries. The thesis was initiated by exploring the utilization and effectiveness of asphaltene-derived carbon fibers (ACFs) in carbon fiber-reinforced composites (CFRCs) produced through additive manufacturing. Leveraging the high aromaticity and carbon content of petroleum asphaltenes, ACFs offer a cost-effective alternative to commercial carbon fibers (CCFs) derived from polyacrylonitrile (PAN). Composites were 3D printed by incorporating different weight proportions (0%, 2.5%, 5% and 7.5%) of chopped ACFs (length 3-4 mm, diameter ~6-12 μm, tensile strength ~500-1150 MPa, tensile modulus ~40-90 GPa) into an acrylonitrile butadiene styrene (ABS) matrix without any post-treatment. Mechanical properties of both ACFs and their derived composites were extensively characterized, including tensile, flexural, hardness and impact properties. Results indicate that incorporating 7.5 wt% ACFs enhanced ABS's flexural and tensile strengths by approximately 20% and 5%, respectively and its corresponding modulus values by about 30% and 34%. Additionally, ABS's hardness improved by 31% with the inclusion of 7.5 wt% ACFs. Despite the lower surface roughness and surface energy of untreated ACFs, the composites exhibited promising performance. To address the poor interfacial adhesion between the hydrophobic, chemically inert ACFs and the polymer matrix, various surface treatments (HNO3, silane, H2O2, etc.) were proposed to introduce polar functional groups and increase surface roughness. Furthermore, the ABS matrix was grafted with maleic anhydride (MA) to facilitate better bonding with surface-functionalized ACFs. This study systematically investigates the effects of these surface modifications on the properties of ACFs and the fiber-matrix interface, demonstrating that surface treatments can significantly enhance the fiber-matrix compatibility of ACF-reinforced composites, making them viable for a wide range of applications.
