description: No abstracts are to be cited without prior reference to the author. The Eastern Channel is a strategic area that supports many human activities from freight to tourism, aggregates extraction, commercial fisheries or windfarms. These activities sharing the same marine space, there is a need for a good understanding of their interactions in order to avoid major spatial conflicts. Besides, their potential interactions with marine populations have not yet been well established. Many Marine Protected Areas have been created in the Channel in the past few years or are still being discussed. Anticipating the consequences of these MPAs on the marine system is necessary to recommend approriate management measures that ensure sustainability of both fish populations and human activities.
Numerical modelling of experimental data of reinforced concrete beam-to-column joints

Publisher: name: University of British Columbia

description: Since the 1970's, increasing attention has been given to seismic design in building codes with emphasis on ductility. Ductile behaviour in reinforced concrete moment resisting frames is important from the point of view of an energy dissipating mechanism. Modern design codes today have stringent guidelines on the design of the beam to column joint region in order to achieve ductile behaviour without brittle shear failure. There are many older buildings, however, that are deficient in strength and ductility with respect to seismic loading. Deficient structures such as these may be retrofitted by encasing the beam to column joint in a steel shell. Cyclic testing of reinforced concrete beam and column sub-assemblies have proven that a very substantial increase in bending and shear strength can be achieved in the joint area by encasing the region with a steel tube and filling the cavity with cement grout. Failures were deflected from the joint area to adjacent members, which were intentionally weakened to form plastic hinges. Subsequent tests on the remaining joint specimens, which forced the failure mechanism into the joint region, provided strength and ductility data for the joint itself. Because experimental testing of scale models can be expensive and at times impractical for every situation that may arise in practice, a non-linear finite element program was written for the analysis of the joint area. The program utilizes plasticity based constitutive descriptions of the concrete and steel material models and intends to be able to predict the behaviour and peak values of the strength envelopes of the joints. Comparisons with available experimental results were encouraging insofar as the plastic behaviour of the concrete and steel were captured. Due to the complex nature of the problem the program was unable to accurately predict the maximum load carrying capacity and more research is required in "fine tuning" the material constitutive models and finite element models. Recommendations for continuing research are given.

description: Although most metal-insulator transitions in doped insulators are generally viewed as Mott transitions, some systems seem to deviate from this scenario. Alkali metal-ammonia solutions are a brilliant example of that. They reveal a phase separation in the range of metal concentrations where a metal-insulator transition occurs. Using a mean spherical approximation for quantum polarizable fluids, we argue that the origin of the metal-insulator transition in such a system is likely similar to that proposed by Herzfeld a long time ago, namely, due to fluctuations of solvated electrons. We also show how the phase separation may appear: the Herzfeld instability of the insulator occurs at a concentration for which the metallic phase is also unstable. As a consequence, the Mott transition cannot occur at low temperatures. The proposed scenario may provide a new insight into the metal-insulator transition in condensed-matter physics.

description: We explore coherent control of Penning and associative ionization in cold collisions of metastable He$^*({2}^3\text{S})$ atoms via the quantum interference between different states of the He$_2^*$ collision complex. By tuning the preparation coefficients of the initial atomic spin states, we can benefit from the quantum interference between molecular channels to maximize or minimize the cross sections for Penning and associative ionization. In particular, we find that we can enhance the ionization ratio by 30% in the cold regime. This work is significant for the coherent control of chemical reactions in the cold and ultracold regime.

description: No abstracts are to be cited without prior reference to the author. In 2003, Belgium was one of the first countries in Europe to start with spatial zoning for the North Sea (= Master Plan) and currently a marine spatial plan (MSP) based on a legally binding process is underway. The journey towards such MSP was turbulent, triggered by several sectoral needs (e.g. offshore energy; nature conservation) and was examined within the MESMA project (Monitoring and Evaluation of Spatially Managed Areas). A number of successful events can be noticed (e.g. the extension of a Special Area of Conservation to 1/3th of the total Belgian part of the North Sea, allocation of an area for renewable energy,... ). Nevertheless, there are also a number of obstacles within the MSP process such as the lack of management plans as well as conflicts with and among the users (e.g. renewable energy versus nature conservation conflicts, etc.). All these events are proceeded by a series of processes, which are documented in this study.

description: The reason of choise of the specific subject was the developed interest for the protected natural habitats, the cross-border prospect of their sustainability and their viable development, as well as the cross-state cooperation for the maintenance and management of the natural resources of the area. The specialized analysis of the architectural landscape in the Cross-border Prespes Park attempts to provide an understanding of the protected area’s landscape structure as well as the possibility of intervention in it under certain circumastances. The thesis contains an applied research at the Hellenic protection part of the Cross-Border Prespes Park. This research focuses on the way of the transition in the landscape, on the established and suggested flow of human resources, with the aim to outline the readability of the landscape, to record the functions of the habitat and its value for the local community. The conclusion that might be extracted from the thesis may be used in order to create certain policies on how to support and strengthen the landscape in terms of planning and management.

description: No abstracts are to be cited without prior reference to the author. Integrated maritime governance is advocated by the European Union. This seeks to coordinate rather than replace sectoral policies. Individually the majority of marine and coastal activities have overarching policy objectives, aimed at progressing that activity. A review of the extent to which current legal and institutional frameworks facilitate or impede integrated maritime governance was a central aim of the FP7 COEXIST project, where existing management approaches to the interaction and colocation of aquaculture, fisheries and other competing sectors were examined. This highlights where there are barriers to, and opportunities for, more efficient management. The review incorporated stakeholder surveys, institutional analysis and an analysis of relevant legislation and policies at EU level. Results confirm that responsibilities remain shared between national, regional and local institutions with little opportunity for horizontal or vertical integration. Whilst there are opportunities for better integration under existing instruments, there remains a disconnect between these strategic management frameworks and experience at the operational level. Law and policy amendments and the proposed Directive on Maritime Spatial Planning and Integrated Coastal Management could provide opportunities to redress existing shortcomings, thereby facilitating implementation of integrated management.

description: The Thousand Pulsar Array (TPA) project currently monitors about 500 pulsars with the sensitive MeerKAT radio telescope by using subarrays to observe multiple sources simultaneously. Here we define the adopted observing strategy, which guarantees that each target is observed long enough to obtain a high fidelity pulse profile, thereby reaching a sufficient precision of a simple pulse shape parameter. This precision is estimated from the contribution of the system noise of the telescope, and the pulse-to-pulse variability of each pulsar, which we quantify under some simplifying assumptions. We test the assumptions and choice of model parameters using data from the MeerKAT 64-dish array, Lovell and Parkes telescopes. We demonstrate that the observing times derived from our method produce high fidelity pulse profiles that meet the needs of the TPA in studying pulse shape variability and pulsar timing. Our method can also be used to compare strategies for observing large numbers of pulsars with telescopes capable of forming multiple subarray configurations. We find that using two 32-dish MeerKAT subarrays is the most efficient strategy for the TPA project. We also find that the ability to observe in different array configurations will become increasingly important for large observing programmes using the Square Kilometre Array telescope.

description: An Andreev pair from a s-wave superconductor (S) entering a conventional gapless charge density wave (CDW) below the Peierls gap dephases on the Fermi wavelength while one particle states are localized on the CDW coherence length. The paths following different sequences of impurities interfere destructively, due to the different electron and hole densities in the CDW. The same conclusion holds for averaging over the conduction channels in the ballistic system. We apply two microscopic approaches to this phenomenon: i) a Blonder, Tinkham, Klapwijk (BTK) approach for a single highly transparent S-CDW interface; and ii) the Hamiltonian approach for the Josephson effect in a clean CDW and a CDW with non magnetic disorder. The Josephson effect through a spin density wave (SDW) is limited by the coherence length, not by the Fermi wave-length.

description: No abstracts are to be cited without prior reference to the author. There is likely to be a rapid increase in the number of tidal stream turbines in the next decade. A major concern is that deep diving seabirds (auks Alcidae sp and cormorants Phalacrocorax sp) may collide with the moving components of devices during foraging dives. However, if individuals do not dive near tidal stream turbines within the tidal pass habitats favoured for installations, then they will not face collision risks. Identifying associations between physical conditions and deep diving seabirds would allow species fine scale foraging distributions within tidal passes to be predicted, leading to estimations of spatial overlap between species foraging distributions and tidal stream turbines. Here we outline a suite of biological and physical datasets from the Fall of Warness, Orkney, UK that have been collated to identify associations between physical conditions and vulnerable species. Preliminary results reveal associations between strong currents and several vulnerable species although seasonal variations were seen. However, the inclusion of more physical conditions in future statistical analysis will allow more precise predictions of species fine-scale distributions. This will lead towards confident estimations of spatial overlap between deep diving seabirds and devices in tidal pass habitats
Superradiant instability of large radius doubly spinning black rings

description: We point out that 5D large radius doubly spinning black rings with rotation along S^1 and S^2 are afflicted by a robust instability. It is triggered by superradiant bound state modes. The Kaluza-Klein momentum of the mode along the ring is responsible for the bound state. This kind of instability in black strings and branes was first suggested by Marolf and Palmer and studied in detail by Cardoso, Lemos and Yoshida. We find the frequency spectrum and timescale of this instability in the black ring background, and show that it is active for large radius rings with large rotation along S^2. We identify the endpoint of the instability and argue that it provides a dynamical mechanism that introduces an upper bound in the rotation of the black ring. To estimate the upper bound, we use the recent black ring model of Hovdebo and Myers, with a minor extension to accommodate an extra small angular momentum. This dynamical bound can be smaller than the Kerr-like bound imposed by regularity at the horizon. Recently, the existence of higher dimensional black rings is being conjectured. They will be stable against this mechanism.

description: CONTEXT: Gravitationally lensed quasars constitute an independent tool to derive H0 through time-delays; they offer as well the opportunity to study the mass distribution and interstellar medium of their lensing galaxies and, through microlensing they also allow one to study details of the emitting source. AIMS: For such studies, one needs to have an excellent knowledge of the close environment of the lensed images in order to model the lensing potential: this means observational data over a large field-of-view and spectroscopy at high spatial resolution. METHODS: We present VIMOS integral field observations around four lensed quasars: HE 0230-2130, RX J0911.4+0551, H 1413+117 and B 1359+154. Using the low, medium and high resolution modes, we study the quasar images and the quasar environments, as well as provide a detailed report of the data reduction. RESULTS: Comparison between the quasar spectra of the different images reveals differences for HE 0230-2130, RX J0911.4+0551 and H 1413+117: flux ratios between the images of the same quasar are different when measured in the emission lines and in the continuum. We have also measured the redshifts of galaxies in the neighborhood of HE 0230-2130 and RX J0911.4+0551 which possibly contribute to the total lensing potential. CONCLUSIONS: A careful analysis reveals that microlensing is the most natural explanation for the (de)magnification of the continuum emitting region of the background sources. In HE 0230-2130, image D is likely to be affected by microlensing magnification; in RX J0911.4+0551, images A1 and A3 are likely to be modified by microlensing de-magnification and in H 1413+117, at least image D is affected by microlensing.

Real-World Data Driven Characterization of Urban Human Mobility Patterns

Publisher: name: Carnegie Mellon University
Year: 2022
Subjects: Applied Computer Science

description: Human movement in urban areas is a complex phenomenon to analyze and understand. The geographical spread of human movement, described by locations between which individuals tend to travel, varies from city to city. The geographical spread of such locations within a city would also vary with time. This thesis explores how to formally analyze and understand human mobility using large sets of realworld data from ride-sharing services for more than a dozen cities and to derive succinct characterizations for large urban areas which account for both geographical and temporal changes. A wide range of machine learning problems require immense amounts of data. To overcome this issue for human mobility, we propose a framework which includes a stochastic graph model, and adversarial networks to generate synthetic humanmobility data which conforms with the geographical and temporal characteristics observed in real data.Deriving interesting insights from large sets of data and applying those to realworld applications can be challenging. Here we also highlight how formal characterizations can be applied to applications like ride pooling and vehicle placement. We also derive performance bounds for online algorithms using city level characterizations. Finally, we provide an open-source framework to understand properties of humanmovement, generate synthetic human mobility data, and apply it to different what-if scenarios for real-world applications. Using such a framework would help publicentities and researchers alike to thoroughly understand a complex and highly relevant phenomenon.Throughout, we link our problem formulations with other domains like social network graphs and online algorithms along with extensive empirical evaluations toincrease our understanding of not just human mobility but established techniques in the linked domains.

description: No abstracts are to be cited without prior reference to the author. We used GPS technology to improve our understanding of how a declining breeding population of a scarce endemic seabird, the great skua (Stercorarius skua), uses the marine environment by tracking the movements and behaviour of breeding adults from two Scottish special protection areas on the Orkney and Shetland Islands. We assessed spatial overlap with a long-term human activity (fishing) and a relatively recent human activity (marine renewable energy generation) to improve our understanding of this species’ response to current and future pressures. These pressures include the increasing development of the marine environment for renewable energy generation and changes to fisheries discard policies. Increasing our understanding of seabird movements at sea in relation to human activities will support marine spatial planning (MSP) by informing the management of sustainable marine activities, the sensitive designation of sites for marine renewable energy development and the implementation of marine protected areas.

description: No abstracts are to be cited without prior reference to the author. The Shetland Islands’ Marine Spatial Plan (SMSP) first developed in 2006 is now progressing towards adoption as Supplementary Guidance (SG) to the Council’s Local Development Plan (LDP), the first statutory plan in the UK. This marks a unique and significant move to standardise the approaches and responsibilities between terrestrial and marine planning jurisdictions and a more integrated approach to MSP and integrated coastal zone management (ICZM). Prior to reaching this stage, a review was carried out to evaluate and monitor the effectiveness of the SMSP to date. This exercise highlighted achievements to date, future challenges and opportunities and helped to guide the development of the forthcoming edition of the SMSP. The sharing of knowledge and practical experiences of MSP and its broader issues ensures an adaptive approach in addressing uncertainty over time. It is also imperative to understand that early ‘pioneers’ in MSP may not get it exactly right on the first attempt but by developing initial precedents and processes, these can be built upon in the future

description: Scalable video coding (SVC) is extended from its predecessor advanced video coding (AVC) because of its flexible transmission to all type of gadgets. However, SVC is more flexible and scalable than AVC, but it is more complex in determining the computations than AVC. The traditional full search method in the standard H.264 SVC consumes more encoding time for computation. This complexity in computation need to be reduced and many fast mode decision (FMD) algorithms were developed, but many fail to balance in all the three measures such as peak signal to noise ratio (PSNR), encoding time and bit rate. In this paper, the proposed optimal mode selection algorithm based on the orientation of pixels achieves better time saving, good PSNR and coding efficiency. The proposed algorithm is compared with the standard H.264 JSVM reference software and found to be 57.44% time saving, 0.43 dB increments in PSNR and 0.23% compression in bit rate.

description: Transmission of forces in static granular materials are studied within the framework of the force network ensemble, by numerically evaluating the mechanical response of hexagonal packings of frictionless grains and rectangular packings of frictional grains. In both cases, close to the point of application of the overload, the response is non-linear and displays two peaks, while at larger length-scales it is linear and elastic-like. The cross-over between these two behaviors occurs at a depth that increases with the magnitude of the overload, and decreases with increasing friction.

description: (Abridged) The colour-magnitude relations of one of the most massive, high redshift clusters of galaxies known have been studied. Photometry has been measured in the V, R, I, z, F606W, F814W, J and K bands to a depth of K*+2.5 and spectroscopy confirms 27 K band selected cluster members. The V-K colours are equivalent to a rest-frame colour of ~2700A-J, and provide a very sensitive measure of star-formation activity. HST ACS imaging has been used to morphologically classify the galaxies. The cluster has a low early-type fraction compared to nearby clusters, with only 33% of the cluster members having types E or S0. The early-type member galaxies form a clear red-sequence in all colours. The scatter and slope of the relations show no evolution compared to the equivalent Coma cluster relations, suggesting the stellar populations are already very old. The normalisation of the relations has been compared to models based on synthetic stellar populations, and are most consistent with stellar populations forming at z>3. Some late-type galaxies were found to lie on the red-sequence, suggesting that they have very similar stellar populations to the early-types. These results present a picture of a cluster in which the early-type galaxies are all old, but in which there must be future morphological transformation of galaxies to match the early-type fraction of nearby clusters. In order to preserve the tight colour-magnitude relation of early-types seen in nearby clusters, the late-type galaxies must transform their colours, through the cessation of star-formation, before the morphological transformation occurs. Such evolution is observed in the late-types lying on the colour-magnitude relation.

description: Fundamental parameters and physical processes leading to the formation of white dwarfs (WDs) may be constrained and refined by discovering WDs in open clusters (OCs). Cluster membership can be utilized to establish the precise distances, luminosities, ages, and progenitor masses of such WDs. We compile a list of probable WDs that are OC members in order to facilitate WD studies that are impractical or difficult to conduct for Galactic field WDs. We use recent catalogs of WDs and OCs that are based on the second data release of the \textit{Gaia} satellite mission (GDR2) to identify WDs that are OC members. This crossmatch is facilitated by the astrometric and photometric data contained in GDR2 and the derived catalogs. Assuming that most of the WD members are of the DA type, we estimate the WD masses, cooling ages, and progenitor masses. We have detected several new likely WD members and reassessed the membership of the literature WDs that had been previously associated with the studied OCs. Several of the recovered WDs fall into the recently reported discontinuity in the initial-final mass relation (IFMR) around $M_{i} \sim 2.0 M_{\odot}$, which allows for tighter constrains on the IFMR in this regime.

A review to determine the need, location, and design of runaway lanes in British Columbia
Creators: name: Yee, Hon Wa
Publisher: name: University of British Columbia
Year: 2009

description: British Columbia's steep mountain highways require runaway lanes to assist heavy vehicles if they lose control. Runaway lanes, or speed control lanes have been implemented in Canadian and American highways for over 40 years. They are used in mountainous regions as a primary tool to minimize the risk and consequences of heavy vehicle runaway accidents. Insufficient vehicle and brake maintenance, improper use of brake check faculties prior to descending steep grades, excessive descent speeds and/or relying primarily on the service brakes to control speed on downgrades leading to excessive brake heating results in a loss of brake capacity. Also, the lack of knowledge of the highway terrain to be encountered contributes to a condition where the driver has insufficient brake capacity to reduce vehicle speed for the road terrain being encountered. Runaway lanes are therefore placed at various locations along steep and/or lengthy downgrades where drivers can utilize them soon after realizing that a potential runaway situation exists. A comprehensive review of previous work relating to runaway lane design was conducted. Full scale tests of several runaway lane designs currently existing in British Columbia were carried out to identify any design deficiencies. In addition, a brake temperature model was evaluated and modified to reflect the eight axle truck configurations existing in British Columbia to devise a simple runaway lane warrant. The final outcome of the research concluded that the arrestor bed type runaway lane is the most suitable for safely stopping the different truck configurations currently existing in British Columbia. In addition, a simple runaway lane warrant based on brake fade temperature was devised and calibrated for an eight axle B-train truck configuration.

description: Training Convolutional Neural Networks (CNNs) for very high resolution images requires a large quantity of high-quality pixel-level annotations, which is extremely labor- and time-consuming to produce. Moreover, professional photo interpreters might have to be involved for guaranteeing the correctness of annotations. To alleviate such a burden, we propose a framework for semantic segmentation of aerial images based on incomplete annotations, where annotators are asked to label a few pixels with easy-to-draw scribbles. To exploit these sparse scribbled annotations, we propose the FEature and Spatial relaTional regulArization (FESTA) method to complement the supervised task with an unsupervised learning signal that accounts for neighbourhood structures both in spatial and feature terms.

description: No abstracts are to be cited without prior reference to the author. How will Natura2000 sites and the introduction of windmill parks in the North Sea impact the fishing sector? To answer this question we have simulated how various closures on the North Sea will affect the economic results of the German and Dutch fishing fleets using the spatial version of FishRent. FishRent is a bio-economic model which simulates fishermen behaviour based on optimal effort allocation. Spatial FishRent has been applied in this paper to estimate the costs of various closure scenarios for German and Dutch trawling fleets catching flatfish and shrimps in the North Sea. The predictions show that the economic effects in terms of lost profit of the planned closures are limited. While there are some considerable closures planned in the North Sea, the fleet segments are quite mobile and thus able to switch to other areas. A contributing factor is the increased biomass of the target species. While some areas may not be accessible to the fishing fleets anymore the biomass is large enough to support more fishing in other areas. However as the fishing intensity in the remaining areas substantially increases it may well be possible that crowding costs will become far more extensive.

On steady-state currents through nano-devices: a scattering-states numerical renormalization group approach to open quantum systems

description: We propose a numerical renormalization group (NRG) approach to steady-state currents through nano-devices. A discretization of the scattering-states continuum ensures the correct boundary condition for an open quantum system. We introduce two degenerate Wilson chains for current carrying left and right-moving electrons reflecting time-reversal symmetry in the absence of a finite bias $V$. We employ the time-dependent NRG to evolve the known steady-state density operator for a non-interacting junction into the density operator of the fully interacting nano-device at finite bias. We calculate the temperature dependent current as function of $V$ and applied external magnetic field using a recently developed algorithm for non-equilibrium spectral functions.

description: ISO-Oph 2 is a wide-separation (240 au) binary system where the primary star harbors a massive (M$_{dust}$ $\sim$40 M$_{\oplus}$) ring-like disk with a dust cavity $\sim$50 au in radius and the secondary hosts a much lighter (M$_{dust}$ $\sim$0.8 M$_{\oplus}$) disk. As part of the high-resolution follow-up of the "Ophiuchus Disk Survey Employing ALMA" (ODISEA) project, we present 1.3 mm continuum and $^{12}$CO molecular line observations of the system at 0''02 (3 au) resolution. We resolve the disk around the primary into two non-axisymmetric rings and find that the disk around the secondary is only $\sim$7 au across and also has a dust cavity (r $\sim$2.2 au). Based on the infrared flux ratio of the system and the M0 spectral type of the primary, we estimate the mass of the companion to be close to the brown dwarf limit. Hence, we conclude that the ISO-Oph 2 system contains the largest and smallest cavities, the smallest measured disk size, and the resolved cavity around the lowest mass object (M$_{\star}$ $\sim$0.08 M$_\odot$) in Ophiuchus. From the $^{12}$CO data, we find a bridge of gas connecting both disks. While the morphology of the rings around the primary might be due to an unseen disturber within the cavity, we speculate that the bridge might indicate an alternative scenario in which the secondary has recently flown by the primary star causing the azimuthal asymmetries in its disk. The ISO-Oph 2 system is therefore a remarkable laboratory to study disk evolution, planet formation, and companion-disk interactions.

Assessment of the snow-cover numerical model crocus-application to avalanches and hydrology
Creators: name: Mingo, Laurent
Publisher: name: University of British Columbia
Year: 2009

description: The French snow-cover numerical model CROCUS was tested with respect to avalanche forecasting issues and hydrological applications under two specific climatic conditions. Mt. Fidelity at Glacier National Park (Selkirk Mountains) and Blackcomb Mt. Resort (South coast Mountins) were chosen for the experiments. These sites are characterized by deep snow-packs (3 to 4 meter snow-pack is common) with moderate snow-pack temperature gradients in the order of 5 °C/m. Numerous time periods can also commonly experience 10 °C/m to 15 °C/m gradients as well as isothermal temperature distributions. Such snow-pack characteristics offer the possibility to assess the performances of the model under various new conditions that differ from previously published work. CROCUS proved itself being very efficient for modeling snow-depth, density and temperature profiles, which are parameters considered important for hydrological modeling. Results show that good performance of the grain simulation is only obtained for particular ranges of snow-pack temperature gradients. For values close to 5 °C/m it is sometime difficult to achieve good simulations and the model has a tendency to mistakenly emphasize facets formation. Suggestions are proposed for the remediation of this behavior. CROCUS' heat exchanges simulations at the surface of the snow-cover were processed as an attempt to track surface hoar occurrences. Encouraging results are shown.
