description: This thesis examines the counter-discourses articulated by Iranian activists’ online memetic resistance sparked by Mahsa Amini’s (alleged) murder by Iran’s Guidance Patrol. Iranian activists resist the Islamic Regime of Iran’s compulsory hijab laws and gendered violence through TikTok memes. Such subversive memetic actions incorporate embodied performances and lived experiences of forced veiling. This research uses Fairclough’s critical discourse analysis (CDA) to examine the counter-discourses constructed through rearticulations of politically fueled memes and identify how TikTok’s affordances facilitate the proliferation of online memetic content. By doing so, this research reveals meanings of bodily autonomy constructed by Iranian women which, in turn, contributes to the creation of the counter-discursive figure of the “good bad hijabi” who resists the embedded misogynistic culture and extreme religious rulings in Iran. Through imitating and rearticulating memetic actions that connect with youth culture, Iranian activists aim to foster transnational feminist practices. While this is the case, feminist coalition building within these protests are minimal as gaps exist in the socio-political understanding of Iran in non-Iranian allyship.

description: This research examines the role of Concrete 3D Printing (C3DP) in meeting the escalating housing demands on Indigenous Reserves in Canada. As a proof of concept, the thesis delves into the development of culturally appropriate on-reserve housing, with a focus on the design, construction using C3DP and evaluation of the "Kakatoosoyiists”, or Star Lodges project located in the Siksika Nation of Alberta, Canada. As the first 3D printed project in the province and the largest of its kind in Canada, the Star Lodges are comprised of 16 transitional homes aimed at providing temporary housing options to community members during emergencies. These homes were designed by the author and the supervisor under the guidance of Blackfoot Elders and Knowledge and built in partnership with Siksika Housing and Nidus 3d, a company specializing in C3DP technology. The project aimed to strategically leverage the advantages of C3DP to streamline the construction process, enhance durability, reduce maintenance costs, and improve the energy performance of the homes. This approach also offered the opportunity of design flexibility, democratizing the design and construction process, and addressing the longstanding housing crisis that has persistently affected Indigenous reserves for generations.

description: By 2015 the advanced versions of the gravitational-wave detectors Virgo and LIGO will be online. They will collect data in coincidence with enough sensitivity to potentially deliver multiple detections of gravitation waves from inspirals of compact-object binaries. This work is focused on understanding the effects introduced by uncertainties in the calibration of the interferometers. We consider plausible calibration errors based on estimates obtained during LIGO's fifth and Virgo's third science runs, which include frequency-dependent amplitude errors of $\sim 10%$ and frequency-dependent phase errors of $\sim 3$ degrees in each instrument. We quantify the consequences of such errors estimating the parameters of inspiraling binaries. We find that the systematics introduced by calibration errors on the inferred values of the chirp mass and mass ratio are smaller than 20% of the statistical measurement uncertainties in parameter estimation for 90% of signals in our mock catalog. Meanwhile, the calibration-induced systematics in the inferred sky location of the signal are smaller than $\sim 50%$ of the statistical uncertainty. We thus conclude that calibration-induced errors at this level are not a significant detriment to accurate parameter estimation.

description: The validity of the fluctuation theorem for entropy production as deduced from the observation of trajectories implicitly requires that all slow degrees of freedom are accessible. We experimentally investigate the role of hidden slow degrees of freedom in a system of two magnetically coupled driven colloidal particles. The apparent entropy production based on the observation of just one particle obeys a fluctuation theorem-like symmetry with a slope of 1 in the short time limit. For longer times, we find a constant slope, but different from 1. We present theoretical arguments for a generic linear behavior both for small and large apparent entropy production but not necessarily throughout. By fine-tuning experimental parameters, such an intermediate nonlinear behavior can indeed be recovered in our system as well.

description: For over twenty years, Indigenous scholars, and their aspiring allies from around the world have been conducting educational research that has generated a wealth of evidence that “learning and teaching are an essential means of protecting and sustaining Indigenous forms of knowledge” (Smith, 2010a, p. 102). Together, their work has informed federal, provincial, and local policies and professional standards to action “Education for Reconciliation” (Government of Alberta, 2024, para. 2) in Canada. One area of focus has been fostering both teacher and “student capacity for intercultural understanding, empathy, and mutual respect” (Truth and Reconciliation Commission of Canada, 2015, p.7). As a non-Indigenous art teacher, school-based leader, and scholar-practitioner, I am personally attuned to how these professional guiding documents have placed increasing pressure on educators across the territories of the Niitsítapi (the Blackfoot speaking people) and the people of the Treaty 7 region in Southern Alberta to examine and evolve their practice to “develop and apply foundational knowledge about First Nations, Métis and Inuit for the benefit of all students” (Alberta Education, 2023c, p. 5). At this time, there exists an “axiological void” (Donald, 2014, p. 2) as to how K-12 art teachers in Moh’kins’tsis/Calgary, Alberta should proceed in this work. Art teachers want to break the cycle of colonial engagements with Indigenous art and culture; however, many are fearful of doing something “wrong” (Scott & Gani, 2018). My collaborative arts-based case study attended to this significant problem of practice to better understand how learning from Indigenous insight and voices can provoke K-12 art educators to take up Indigenous art rooted with/in this place in good and ethical ways in their classrooms.
Life Cycle Assessment (LCA) and Techno-Economic Assessment (TEA) of Emerging Technologies: A Case Study of Laboratory Based Carbon Fiber Production from Alberta Oilsands Asphaltene (AOA)

description: Life cycle assessment (LCA) and techno-economic assessment (TEA) techniques are widely performed in commercial-scale technologies to quantify environmental and economic impacts. Applying LCA and TEA to emerging technologies can help technology developers identify opportunities to improve technical performance, reduce cost and environmental impacts, and evaluate scaling strategies. Existing LCA and TEA frameworks are not easily applied to emerging technologies at the laboratory-scale for a variety of reasons, including difficulty in collecting comprehensive and representative data, high variability in measured performance, and uncertainty over how laboratory-scale performance may scale to a commercial process. These challenges are examined through a case study centered around the manufacturing of carbon fiber using Alberta Oilsands Asphaltene (AOA). This thesis documents the LCA and TEA of an unoptimized laboratory-scale AOA carbon fiber manufacturing process with the goal of forecasting the potential environmental and economic impacts of a future commercial-scale AOA manufacturing process. Given its high carbon content, AOA has the potential to be a valuable precursor in carbon fiber manufacturing and could be comparable to incumbent, polyacrylonitrile (PAN) based carbon fibers. As the production yield of AOA carbon fiber production increases from 23% to 53%, the estimated cost ranges from USD 22.4 to 9.6 per kg, and the corresponding greenhouse gas emissions (GHG) vary from 18.2 to 8.6 kg CO2 eq/kg. In comparison to PAN, the estimated AOA carbon fibers had significantly lower costs and emissions. However, a direct comparison of emerging AOA carbon fiber manufacturing with the commercial PAN carbon fiber manufacturing may not be the most prudent approach. Different scaling approaches, availability of data, and technological and market uncertainties can lead to substantial shifts in LCA and TEA results of an emerging technology. The LCA and TEA findings of this thesis benefit three primary groups: technology developers, decision makers, and practitioners in the field of LCA and TEA. Technology developers and decision-makers can utilize these findings to bridge the gap between lab and commercial processes, considering environmental and economic factors. The thesis explores how practitioners should interpret results, particularly from the perspectives of technology developers and decision-makers.

description: Motivated by recent experiments, we investigate the system of isotropically-interacting bosons with Rashba spin-orbit coupling. At the non-interacting level, there is a macroscopic ground-state degeneracy due to the many ways bosons can occupy the Rashba spectrum. Interactions treated at the mean-field level restrict the possible ground-state configurations, but there remains an accidental degeneracy not corresponding to any symmetry of the Hamiltonian, indicating the importance of fluctuations. By finding analytical expressions for the collective excitations in the long-wavelength limit and through numerical solution of the full Bogoliubov- de Gennes equations, we show that the system condenses into a single momentum state of the Rashba spectrum via the mechanism of order by disorder. We show that in 3D the quantum depletion for this system is small, while the thermal depletion has an infrared logarithmic divergence, which is removed for finite-size systems. In 2D, on the other hand, thermal fluctuations destabilize the system.

description: Semantic segmentation has shown a significant success for achieving comprehensive scene understanding in real-time perception and urban modeling. Over the recent years, there have been significant advancements in semantic segmentation for LiDAR point clouds, largely the adopting of deep learning techniques. There are the related works of 3D semantic segmentation, including neural network models to process converted voxels, points, and graphs. However, point-based methods are not taken into account local structure feature, resulting in a lack of fine-grained features and limited generalization. Additionally, these models do not take full advantage of the high-level geometric correlations among local neighbors, resulting in low semantic segmentation accuracy. The use of voxel-based methods for balancing precision and computational efficiency is a useful technique. Still, voxel-based representation of point clouds is inefficient and tends to ignore fine details. Little research has investigated using graph-based methods for LiDAR point cloud semantic segmentation. Our work demonstrates the feasibility of using graph representation for highly accurate semantic segmentation in a point cloud. Other problems in the existing methods are high computational and memory requirements. Self-supervised learning on large unlabeled datasets is one way to reduce the number of manual annotations needed. In this thesis, we explore that leverage the combination self-supervised contrastive learning and graph-based method to overcome the semantic segmentation challenges of large-scale point clouds. An experimental qualitative and quantitative analysis of our method shows that the proposed approach can beat previous approaches on S3DIS and SemanticKITTI datasets for the task of LiDAR point cloud semantic segmentation.

description: The topological insulator Bi2Se3 shows a Raman scattering response related to topologically protected surface states amplified by a resonant interband transition. Most significantly this signal has a characteristic Lorentzian lineshape and spin-helical symmetry due to collision dominated scattering of Dirac states at the Fermi level E_F on bulk valence states. Its resonance energy, temperature and doping dependence points to a high selectivity of this process. Its scattering rate (Gamma=40 cm-1=5 meV) is comparable to earlier observations, e.g. in spin-polaron systems. Although the observation of topological surface states in Raman scattering is limited to resonance conditions, this study represents a quite clean case which is not polluted by symmetry forbidden contributions from the bulk

Hypercapnic Hemotherapy to Stabilize Blood Flow in the Acute Phase of Spinal Cord Injury

Subjects: subject: Blood Flow
subject: Spinal Cord Injury

subject: Neuroscience

description: Spinal cord injury (SCI) results in disturbances to sensory, motor, and/or autonomic function and impairs quality of life. There is a lack of standardized management strategies after SCI due to the lack of consensus regarding the use of corticosteroids, optimal timing of surgical intervention, and the type and timing of rehabilitation, amongst other things. Secondary damage after the initial trauma involves ischemia, hypoxia, and vascular damage, amongst other effects. This secondary insult during the acute phase of SCI has been shown to underlie approximately half of the final injury severity. There are no current therapies targeting the acute phase of SCI that could help reduce the severity of final injury. My project is focused on addressing this gap in finding an effective intervention during the acute phase of SCI to mitigate the severity of the final injury. My thesis aimed to characterize how hemodynamic parameters are impaired during the acute phase of SCI and if inspired carbon dioxide (CO2) could increase these hemodynamic parameters. We aimed to develop a method to stabilize blood flow (BF) using closed-loop during the acute phase of SCI in mice. I showed that penumbral BF and related hemodynamic parameters are impaired during the acute phase of SCI and that hypercapnia can stabilize these parameters to pre-SCI levels. I then developed a closed-loop system that titrated CO2 to keep penumbral BF around a pre-determined setpoint during the acute phase of SCI. The methods established in this study are Laser Doppler Flowmetry, Near-Infrared Spectroscopy, and O2 MicroOptode technology which have never all been studied in a SCI mouse model. This novel methodology will lead the way for future studies that aim to investigate hemodynamic parameters in a SCI mouse model. This project is significant because a closed-loop system has the potential to be an early therapy targeting the acute phase of SCI.

description: We explore the relationship between two figures of merit for an adiabatic quantum computation process: the success probability $P$ and the minimum gap $Δ_{min}$ between the ground and first excited states, investigating to what extent the success probability for an ensemble of problem Hamiltonians can be fitted by a function of $Δ_{min}$ and the computation time $T$. We study a generic adiabatic algorithm and show that a rich structure exists in the distribution of $P$ and $Δ_{min}$. In the case of two qubits, $P$ is to a good approximation a function of $Δ_{min}$, of the stage in the evolution at which the minimum occurs and of $T$. This structure persists in examples of larger systems.

Input Visualization: Collecting and Modifying Data with Visual Representations

Publisher: name: ACM
Year: 2024

description: We examine input visualizations, visual representations that are designed to collect (and represent) new data rather than encode preexisting datasets. Information visualization is commonly used to reveal insights and stories within existing data. As a result, most contemporary visualization approaches assume existing datasets as the starting point for design, through which that data is mapped to visual encodings. Meanwhile, the implications of visualizations as inputs and as data sources have received little attention—despite the existence of visual and physical examples stretching back centuries. In this paper, we present a design space of 50 input visualizations analyzing their visual representation, data, artifact, context, and input. Based on this, we identify input modalities, purposes of input visualizations, and a set of design considerations. Finally, we discuss the relationship between input visualization and traditional visualization design and suggest opportunities for future research to better understand these visual representations and their potential.

description: In the problem of quantum state discrimination, one has to determine by measurements the state of a quantum system, based on the a priori side information that the true state is one of two given and completely known states, rho or sigma. In general, it is not possible to decide the identity of the true state with certainty, and the optimal measurement strategy depends on whether the two possible errors (mistaking rho for sigma, or the other way around) are treated as of equal importance or not. Results on the quantum Chernoff and Hoeffding bounds and the quantum Stein's lemma show that, if several copies of the system are available then the optimal error probabilities decay exponentially in the number of copies, and the decay rate is given by a certain statistical distance between rho and sigma (the Chernoff distance, the Hoeffding distances, and the relative entropy, respectively). While these results provide a complete solution to the asymptotic problem, they are not completely satisfying from a practical point of view. Indeed, in realistic scenarios one has access only to finitely many copies of a system, and therefore it is desirable to have bounds on the error probabilities for finite sample size. In this paper we provide finite-size bounds on the so-called Stein errors, the Chernoff errors, the Hoeffding errors and the mixed error probabilities related to the Chernoff and the Hoeffding errors.

Comparisons of auditory steady-state response and behavioural air- and bone-conduction thresholds in infants and adults with normal hearing
Creators: name: Casey, Kelly-Ann
Publisher: name: University of British Columbia
Year: 2012

description: To improve our understanding of normal responses in infants, the present study compares air-conduction (AC) and bone-conduction (BC) auditory thresholds using both the auditory steady-state response (ASSR) and behavioural testing methods in normal-hearing infants (6-18 months of age) and adults. There are no correction factors available for estimating BC behavioural thresholds; this is a limiting factor to clinical implementation of the ASSR. Additionally, previous studies have reported that ASSR and visual reinforcement audiometry (VRA) thresholds (in dB HL) to air- and bone-conducted stimuli have different frequency-dependent trends and suggest that infants present with an air-bone gap that is not attributable to a conductive pathology; however, this relationship has not been assessed directly. The objectives of the present study are: (i) to compare BC thresholds between methods and provide the initial step towards positing correction factors to predict BC behavioural thresholds and; (ii) to directly compare AC and BC thresholds to provide a more accurate estimation of the maturational ABG. Thresholds were estimated at 500–4000 Hz using AM² stimuli for ASSRs and warbled-tone stimuli for behavioural testing. The results indicated that BC thresholds were, on average, 7–16 dB poorer for ASSR compared to VRA, but varied largely across infants. As expected for the ASSR, frequency-dependent differences in BC sensitivity were found— the 500- and 1000-Hz thresholds were better than the 2000-Hz threshold. For AC ASSR, the 500-Hz thresholds were higher than the other frequencies. There was a tendency for infant and adult ASSR thresholds to differ for BC, but not for AC. Behavioural thresholds for AC and BC were similar between infants and adults and across frequency. The results support the presence of a clinically significant maturational ABG (14 and 17 dB) in the low frequencies for infant ASSRs. The infant behavioural ABG also appeared at 500 Hz, as was posited by Hulecki and Small (2011), but was too small to be practically significant. Clinical consideration of the maturational ABG seems warranted when using ASSRs, but not for VRA. The results also provided preliminary normal levels for AC and BC ASSRs to AM² stimuli.

description: Literacy programs and curricula define literacy primarily through cognition, and this privileges an assumption that all learning is situated in the brain, separate from the body. Early-years classrooms are being filled with literacy programs designed with this definition in mind, and as a result, play is diminishing from these classrooms. Posthumanist theoretical perspectives identify the role of the body in learning, identifying play as an example of embodied learning. This study considers the role of the mind and body in embodied literacy-learning through play. The literature review considers posthumanist theories and literacy while also identifying research surrounding playful literacy learning in the 21st century. The context of this study is a Grade 1 classroom in an urban centre that borders a large city in Western Canada. The observations occurred over four months during the daily 45-minute free playtime. The data collection consisted of unstructured interviews, images, videos, and observational notes. Rhizoanalysis was used to identify the emergent nature of embodied literacy practices through play by mapping entities of humans, materials, and language in the play assemblages. Additionally, writing was used as a method of analysis through the creation of data stories, which are shared in the findings chapters. This case study research thinks with posthumanist concepts as the Grade 1 play stories were explored. In identifying embodied literacy practices through play, the findings of this study challenge traditional notions of play and literacy-supporting play as a generative means for literacy learning in the early years classroom.

description: In this article we explore the duality between the low energy effective theory of five-dimensional N=1 SU(N)^{M-1} and SU(M)^{N-1} linear quiver gauge theories compactified on S^1. The theories we study are the five-dimensional uplifts of four-dimensional superconformal linear quivers. We study this duality by comparing the Seiberg-Witten curves and the Nekrasov partition functions of the two dual theories. The Seiberg-Witten curves are obtained by minimizing the worldvolume of an M5-brane with nontrivial geometry. Nekrasov partition functions are computed using topological string theory. The result of our study is a map between the gauge theory parameters, i.e., Coulomb moduli, masses and UV coupling constants, of the two dual theories. Apart from the obvious physical interest, this duality also leads to compelling mathematical identities. Through the AGTW conjecture these five-dimentional gauge theories are related to q-deformed Liouville and Toda SCFTs in two-dimensions. The duality we study implies the relations between Liouville and Toda correlation functions through the map we derive.

description: Though the bulk of the observed optical flux from the discs of intermediate-redshift lensed quasars is formed well outside the region of strong relativistic boosting and light-bending, relativistic effects have important influence on microlensing curves. The reason is in the divergent nature of amplification factors near fold caustics increasingly sensitive to small spatial size details. Higher-order disc images produced by strong light bending around the black hole may affect the amplification curves, making a contribution of up to several percent near maximum amplification. In accordance with theoretical predictions, some of the observed high-amplification events possess fine structure. Here we consider three putative caustic crossing events, one by SBS1520+530 and two events for individual images of the Einstein's cross (QSO J2237+0305). Using relativistic disc models allows to improve the fits, but the required inclinations are high, about 70deg or larger. Such high inclinations apparently contradict the absence of any strong absorption that is likely to arise if a disc is observed edge-on through a dust torus. Still, the high inclinations are required only for the central parts of the disc, that allows the disc itself to be initially tilted by 60-90deg with respect to the black hole and aligned toward the black hole equatorial plane near the last stable orbit radius. For SBS1520+530, an alternative explanation for the observed amplification curve is a superposition of two subsequent fold caustic crossings. While relativistic disc models favour black hole masses ~10^10 solar (several times higher than the virial estimates) or small Eddington ratios, this model is consistent with the observed distribution of galaxies over peculiar velocities only if the black hole mass is about 3 10^8 solar.

description: The condensing solvent bitumen recovery process is a promising alternative to steam-assisted processes in terms of greenhouse gas emissions and energy consumption reduction. In this process, the solvent vapor injected into the reservoir condenses when it contacts the colder bitumen and the bitumen diffuses into the condensed liquid. The process has been piloted but field implementation is impeded by the absence of a reliable model to upscale laboratory measurements to the field scale. The details of the underlying physical mechanisms of this process (gravity drainage and mass transfer) are not fully understood, and predictive models are lacking. This thesis focuses on the little-investigated role of solvent flow rate, permeability and irreducible water saturation in condensing solvent processes. In order to better understand and represent the mechanisms controlling the process, a packed Hele-Shaw type apparatus was partially filled with bitumen with a sloped interface and liquid toluene was flowed on top of the bitumen layer at a fixed flow rate. The experiments were performed with silica sands and glass beads with and without irreducible water saturation. Toluene volumetric flow rates between 0.5 to 15 cm³/min and permeabilities within the range of 47 to 254 D were considered. Bitumen and solvent recoveries were measured over time and the change in bitumen profile was tracked with a camera. The key mechanisms of the process were verified to be diffusion of bitumen into solvent through convective mass transfer and convective flow of the resulting mixture in the drainage layer by gravity. The high dilution (high flow rate) data were predicted with an analytical model obtained from the solution of Fick’s second law of diffusion for the effective mass transfer of bitumen into the flowing drainage layer according to Darcy’s law. The full range of data was matched with a numerical model based on convective mass transfer of bitumen into the drainage layer using a correlated convective mass transfer coefficient derived from effective molecular diffusivity and Darcy flow. The correlation has only one adjustable parameter which was constant for steady-state mass transfer in the semi-infinite acting regime. Neither model required mechanical dispersion even in presence of irreducible water. A square root dependence of mass flux versus permeability was observed, consistent with molecular diffusion with no mechanical dispersion.

description: We study the hadron yield correlation in the combination models in high energy heavy ion collisions. We derive the relationship between the average yields of different hadrons produced in the combination of a system consisting of equal number of quarks and antiquarks. We present the results for the directly produced hadrons as well as those for the final hadrons including the strong and electromagnetic decay contributions. We also study the net quark influence by considering the case when the number of quarks is larger than that of the antiquarks. We make comparison with the data wherever possible.

Computational studies of the genome dynamics of mammalian transposable elements and their relationships to genes
Creators: name: Zhang, Ying

description: Sequences derived from transposable elements (TEs) comprise nearly 40 - 50% of the genomic DNA of most mammalian species, including mouse and human. However, what impact they may exert on their hosts is an intriguing question. Originally considered as merely genomic parasites or “selfish DNA”, these mobile elements show their detrimental effects through a variety of mechanisms, from physical DNA disruption to epigenetic regulation. On the other hand, evidence has been mounting to suggest that TEs sometimes may also play important roles by participating in essential biological processes in the host cell. The dual-roles of TE-host interactions make it critical for us to understand the relationship between TEs and the host, which may ultimately help us to better understand both normal cellular functions and disease. This thesis encompasses my three genome-wide computational studies of TE-gene dynamics in mammals. In the first, I identified high levels of TE insertional polymorphisms among inbred mouse strains, and systematically analyzed their distributional features and biological effects, through mining tens of millions of mouse genomic DNA sequences. In the second, I examined the properties of TEs located in introns, and identified key factors, such as the distance to the intron-exon boundary, insertional orientation, and proximity to splice sites, that influence the probability that TEs will be retained in genes. In the third, a study specifically focused on genes with extremely high or low TE content in three mammalian species, I showed associations between TE density and the function/conservation of genes, as well as the relevance of chromatin state to TE accumulation in genes. While most of my results clearly support the idea that today’s TE distribution pattern is an outcome of natural selection or genetic drift during evolution, the final part of my work, which compares TE density to chromatin state in embryonic stem cells, suggests that traces of the initial integration preference of TEs still exist. Taken together, these results demonstrated the effects of both initial TE integration and natural selection in shaping the landscape of today’s mammalian genomes and, most importantly, shed light on the roles of mobile elements in evolution.

Optimal Configurations for Urban Transit: A Study on Bus and Express Network Design via Analytical Approaches and Mathematical Programming

description: The Public Transit Network Design Problem (PTNDP), particularly the Public Bus Transit Network Design Problem (PBTNDP) and Express Transit Network Design Problem (ETNDP), is a key area in transportation research. Analytical approaches and mathematical programming are widely used methodologies in this field. Mathematical programming is particularly effective in handling complex problems and capturing real-world conditions. However, mathematical programming often acts as "black boxes" and offers limited insights into the problem. Conversely, analytical approaches provide deeper insights into the relationships between decision variables and problem parameters, though they sometimes necessitate simplifications that overlook certain real-world nuances. A comprehensive review of the applications of both analytical approaches and mathematical programming in the problems considered in this thesis is presented in Chapter 2. This thesis endeavors to explore three major problems related to the PTNDP by employing both analytical approaches and mathematical programming. In Chapter 3, the focus is on a single many-to-many public bus transit line and analytical approaches are used to model headway setting and vehicle sizing problems under varying demand and crowding conditions and in three different scenarios. In Chapter 4, the focus shifts to joint transit network design and headway setting problems for Public Bus Transit Systems (PBTSs) at the network level. Analyzing single-mode and bi-modal transit networks in a rectangular city, this chapter explores various routing schemes, including local buses and integrated local-express services. Chapter 5 delves into the ETNDP within a real-world urban framework, employing a hybrid approach of analytical methods and mathematical programming. A two-stage approach is suggested for the bi-modal surface ETNDP. The first stage employs analytical approaches to establish a methodology for identifying optimal station locations for different transit systems. In the second stage, first a mathematical programming is proposed to determine the optimal transit express routes and the transit technology of each transit route. Then, a metaheuristic algorithm based on the Genetic Algorithm is introduced to solve the proposed mathematical programming for real size transit networks. A case study of Calgary, Canada, demonstrates the applicability of the proposed methodologies in Chapter 6.
