description: Over the past few years a major effort has been put into the exploration of potential sites for the deployment of submillimetre astronomical facilities. Amongst the most important sites are Dome C and Dome A on the Antarctic Plateau, and the Chajnantor area in Chile. In this context, we report on measurements of the sky opacity at 200 um over a period of three years at the French-Italian station, Concordia, at Dome C, Antarctica. We also present some solutions to the challenges of operating in the harsh polar environ- ment. Dome C offers exceptional conditions in terms of absolute atmospheric transmission and stability for submillimetre astron- omy. Over the austral winter the PWV exhibits long periods during which it is stable and at a very low level (0.1 to 0.3 mm). Higher values (0.2 to 0.8 mm) of PWV are observed during the short summer period. Based on observations over three years, a transmission of around 50% at 350 um is achieved for 75% of the time. The 200-um window opens with a typical transmission of 10% to 15% for 25% of the time. Dome C is one of the best accessible sites on Earth for submillimetre astronomy. Observations at 350 or 450 μm are possible all year round, and the 200-um window opens long enough and with a sufficient transparency to be useful. Although the polar environment severely constrains hardware design, a permanent observatory with appropriate technical capabilities is feasible. Because of the very good astronomical conditions, high angular resolution and time series (multi-year) observations at Dome C with a medium size single dish telescope would enable unique studies to be conducted, some of which are not otherwise feasible even from space.

description: Particle IDentification (PID) is fundamental to particle physics experiments. This paper reviews PID strategies and methods used by the large LHC experiments, which provide outstanding examples of the state-of-the-art. The first part focuses on the general design of these experiments with respect to PID and the technologies used. Three PID techniques are discussed in more detail: ionization measurements, time-of-flight measurements and Cherenkov imaging. Four examples of the implementation of these techniques at the LHC are given, together with selections of relevant examples from other experiments and short overviews on new developments. Finally, the Alpha Magnetic Spectrometer (AMS 02) experiment is briefly described as an impressive example of a space-based experiment using a number of familiar PID techniques.

description: In nuclear engineering studies, uncertainty and sensitivity analyses of simulation computer codes can be faced to the complexity of the input and/or the output variables. If these variables represent a transient or a spatial phenomenon, the difficulty is to provide tool adapted to their functional nature. In this paper, we describe useful visualization tools in the context of uncertainty analysis of model transient outputs. Our application involves thermal-hydraulic computations for safety studies of nuclear pressurized water reactors.

description: Quantitative assessment of the uncertainties tainting the results of computer simulations is nowadays a major topic of interest in both industrial and scientific communities. One of the key issues in such studies is to get information about the output when the numerical simulations are expensive to run. This paper considers the problem of exploring the whole space of variations of the computer model input variables in the context of a large dimensional exploration space. Various properties of space filling designs are justified: interpoint-distance, discrepancy, minimum spanning tree criteria. A specific class of design, the optimized Latin Hypercube Sample, is considered. Several optimization algorithms, coming from the literature, are studied in terms of convergence speed, robustness to subprojection and space filling properties of the resulting design. Some recommendations for building such designs are given. Finally, another contribution of this paper is the deep analysis of the space filling properties of the design 2D-subprojections.

description: Motivated by the underlying desire to identify novel, physically reasonable resource states for measurement-based quantum computation (MBQC), this thesis explores two seemingly unrelated topics in some detail. The first is a study of the circumstances under which multiqubit quantum states that are equivalent to cluster states of the same size under stochastic local operations and classical communication (SLOCC) are either deterministic or probabilistic resource states, with the aim of identifying new resource states that are related to, but non-trivially different from, the cluster states.The second is an analysis of the properties of the ground state of a potentially physically realisable coupled-cavity quantum electrodynamics model called the Jaynes-Cummings-Hubbard (JCH) model. The hope is that the ground state of the model can in fact serve as a universal resource for MBQC. In the first study, I identify two classes of 1D states in the SLOCC-equivalence class of 1D cluster states that constitute resources for random-length single-qubit rotations, in one case quasi-deterministically (N-U-N states) and in another probabilistically (B-U-B states). In contrast to the cluster states, the N-U-N states exhibit spin correlation functions that decay exponentially with distance, while the B-U-B states can be arbitrarily locally pure. I also show that a two-dimensional square N-U-N lattice is a universal resource for quasi-deterministic measurement-based quantum computation, and that cubic B-U-B states can be locally converted to 2D universal resource states. In the second study, the Density Matrix Renormalization Group (DMRG) algorithm is used to characterize the ground states of the 1D JCH model in the regime of low photon densities, and compare it to the 1D ground state of the Bose-Hubbard (BH) model. Numerical results indicate that a Tonks-Girardeau regime, in which the photons are strongly fermionized, appears between the Mott-insulating and superfluid phases as a function of the intercavity coupling. The final chapter of the thesis outlines the initial progress that I have made in determining whether the 1D JCH ground state can serve as a resource for universal single-qubit rotations in the MBQC picture, as well as directions for future investigation.

description: Spin-only approaches to anisotropic effects in strongly interacting materials are often insufficient for systems close to the Mott regime. Within a model context, here the consequences of the low-symmetry relevant Dzyaloshinskii-Moriya (DM) interaction are studied for strongly correlated, but overall itinerant, systems. Namely, we investigate the Hubbard bilayer model supplemented by a DM term at half filling and in the hole-doped regime. As an add-on, further results for the two- impurity Anderson model with DM interaction are also provided. The model Hamiltonians are treated by means of the rotational invariant slave boson technique at saddle point within a (cellular) cluster approach. Already small values of the anisotropic interaction prove to have a strong influence on the phases and correlation functions with increasing U. An intriguing metallic spin-flop phase is found in the doped bilayer model and a reduction of the RKKY exchange in the two-impurity model.

subject: transformative

description: This paper explores the transformative learning experiences of nine generous volunteers whose change experience was catalyzed by fiction. Using narrative methodology (Clandinin & Connelly, 2000), volunteer experiences were analyzed in a three-dimensional inquiry space based on temporality (i.e., past, present, and future), sociality (i.e., relationship), and place. Commonalities included the readers’ love of fiction, type of fiction, informal learning experienced, evidence of change, and the role passage of time played in the experience. Links are made from their experiences to adult development, complex catalysts, the roles of emotion and motivation, our storied pasts, neuroplasticity, sustaining change, and motivation for change. Trends in the data compiled in this narrative-based, qualitative study add nuances of interest to adult educators hoping to promote transformative learning. The key to each participant’s transformative experience was the combination of cognitive, affective, and contextual meaning conferred by the reader on what they read. The four types of change revealed (i.e., formative, incremental, influential, epochal) coincided with the stages of adult development (i.e., adolescence, young adulthood, middle adulthood, maturity) at which they occurred as proposed by Erikson (1968). It was found that the interviewees were influenced greatly by both emotion and motivation, moving from a purely rational to integral, holistic approach to learning.
An Integrated Approach for Precision Machining of Freeform Surfaces

description: Freeform surfaces, also called sculptured surfaces, have been increasingly used in different industries such as automotive, aerospace, and die and mold manufacturing. Increasing precision requirements for products with freeform surfaces have led to significant challenges for manufacturing companies. Multi-axis CNC machining is the primary method to manufacture these freeform surfaces. Prediction of machining errors with different geometric shapes under varying machining conditions is the key to improve quality in freeform surface manufacturing. An integrated approach for precision machining of freeform surfaces has been developed in this research. In the first step of this approach, geometric errors of machine tool and process-related errors are identified and compensated. Geometric errors of machine tool are identified through a newly developed offline identification method using the kinematic modeling of machine tool and magnetic double ball bar measurement of the machine's volumetric errors. Process-related errors are modeled as functions of machining process and freeform surface parameters, and measured using on-machine inspection in a multi-layer machining method. These identified error sources are then compensated through tool path re-planning using the mirror approach. In the second step of the integrated approach, the machined surface is inspected to identify and remove any residual errors on the surface. Since comparison between manufactured surface and design surface is conducted by aligning the two surfaces in different coordinate systems, an optimization method is introduced to identify the best alignment with minimum area of the error regions to reduce the re-machining efforts. When error regions on the manufactured surface are identified, CNC machining tool paths need to be generated to remove these errors. Since various tool path generation methods may be used for the identified error islands on the surface, mapping between the error islands and the tool path generation methods needs to be studied. In this research, the mapping is conducted by analyzing the geometric characteristics of each error island and the capabilities of the tool path generation algorithms. The results obtained through different evaluation methods, such as simulations, measurement of machine tool's volumetric accuracy, and machining experiments, reveal significant improvement in the accuracy and efficiency of freeform surface machining process.
Universal monopole scaling near transitions from the Coulomb phase

description: Certain frustrated systems, including spin ice and dimer models, exhibit a Coulomb phase at low temperatures, with power-law correlations and fractionalized monopole excitations. Transitions out of this phase, at which the effective gauge theory becomes confining, provide examples of unconventional criticality. This work studies the behavior at nonzero monopole density near such transitions, using scaling theory to arrive at universal expressions for the crossover phenomena. For a particular transition in spin ice, quantitative predictions are made through a duality mapping to the XY model, and confirmed using Monte Carlo simulations.

description: Current models of island biogeography treat endemic and non-endemic species as if they were functionally equivalent, focussing primarily on species richness. Thus, the functional composition of island biotas in relation to island biogeographical variables remains largely unknown. Using plant trait data (plant height, leaf area and flower length) for 895 native species in the Canary Islands, we related functional trait distinctiveness and climate rarity for endemic and non-endemic species and island ages. Endemics showed a link to climatically rare conditions that is consistent with island geological change through time. However, functional trait distinctiveness did not differ between endemics and non-endemics and remained constant with island age. Thus, there is no obvious link between trait distinctiveness and occupancy of rare climates, at least for the traits measured here, suggesting that treating endemic and non-endemic species as functionally equivalent in island biogeography is not fundamentally wrong.
Private social capital and the construction of mastery

Publisher: name: University of British Columbia
Year: 2010

description: Based on the data of the General Social Survey GSS cycle 17 (GSS 17) carried out in 2003, this study tests the relationship between private social capital and the perceived level of mastery. Private social capital has been defined as social networks composed of relatives, friends and neighbors and the type of communication and level of reciprocity they have with the individual. Mastery is a psychological learned trait that gives individuals a sense of control over the positive and negative outcomes of their lives. The notions of empowerment, self efficacy, leadership and initiative are associated with mastery and are considered as valuable resources, with positive impact in fields like health, well being and happiness, for the individuals. This study tests in particular four hypotheses that examine the relationship between private social capital and mastery. The four hypotheses propose the following: a) the larger the social network, the greater the mastery level b) the more frequent the contact, the greater the mastery level, c) the more favours received, the greater the mastery level and d) the more favours given, the higher the mastery level in the individual. The results indicate that frequency of contact, size of network, in particular network size of close members are significant and positively related to mastery; the numbers of favours given are all positively associated with mastery but no significant, finally favours received are not are significantly associated with mastery. This study suggests that increasing social interaction with our private social network of members than one’s feels close has a positive impact on the mastery level of individuals, despite the lack of reciprocity in the relationship.

description: Although OGLE-TR-56b was the second transiting exoplanet discovered, only one light curve, observed in 2006, has been published besides the discovery data. We present twenty-one light curves of nineteen different transits observed between July 2003 and July 2009 with the Magellan Telescopes and Gemini South. The combined analysis of the new light curves confirms a slightly inflated planetary radius relative to model predictions, with R_p = 1.378 +/- 0.090 R_J. However, the values found for the transit duration, semimajor axis, and inclination values differ significantly from the previous result, likely due to systematic errors. The new semimajor axis and inclination, a = 0.01942 +/- 0.00015 AU and i = 73.72 +/- 0.18 degrees, are smaller than previously reported, while the total duration, T_14 = 7931 +/- 38 s, is 18 minutes longer. The transit midtimes have errors from 23 s to several minutes, and no evidence is seen for transit midtime or duration variations. Similarly, no change is seen in the orbital period, implying a nominal stellar tidal decay factor of Q_* = 10^7, with a three-sigma lower limit of 10^5.7.

description: Objective: We conducted a scoping review with the aim of comprehensively investigating what tools or methods have been examined in general practice research that capture a wide range of psychosocial problems (PSPs) and serve to identify patients and highlight their characteristics. Methods: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews and the Joanna Briggs Institute Reviewer’s Manual on scoping reviews. A systematic search was conducted in four electronic databases (Medline [Ovid], Web of Science Core Collection, PsycInfo, Cochrane Library) for quantitative and qualitative studies in English, Spanish, French, and German with no time limit. The protocol was registered with Open Science Framework and published in BMJ Open. Results: Of the 839 articles identified, 66 met the criteria for study eligibility, from which 61 instruments were identified. The publications were from 18 different countries, with most studies employing an observational design and including mostly adult patients. Among all instruments, 22 were reported as validated, which we present in this paper. Overall, quality criteria were reported differently, with studies generally providing little detail. Most of the instruments were used as paper and pencil questionnaires. We found considerable heterogeneity in the theoretical conceptualisation, definition, and measurement of PSPs, ranging from psychiatric case findings to specific social problems. Discussion and conclusion: This review presents a number of tools and methods that have been studied and used in general practice research. Adapted and tailored to local circumstances, practice populations, and needs, they could be useful for identifying patients with PSPs in daily GP practice; however, this requires further research. Given the heterogeneity of studies and instruments, future research efforts should include both a more structured evaluation of instruments and the incorporation of consensus methods to move forward from instrument research to actual use in daily practice.

description: We explore some aspects of phase transitions in cellular automata. We start recalling the standard formulation of statistical mechanics of discrete systems (Ising model), illustrating the Monte Carlo approach as Markov chains and stochastic processes. We then formulate the cellular automaton problem using simple models, and illustrate different types of possible phase transitions: density phase transitions of first and second order, damage spreading, dilution of deterministic rules, asynchronism-induced transitions, synchronization phenomena, chaotic phase transitions and the influence of the topology. We illustrate the improved mean-field techniques and the phenomenological renormalization group approach.

We then study the behaviour of this propagator for different values of the gauge parameters. We will show that in any gauge, apart from the Landau gauge, the graviton propagator in the AdS spacetime contains a complicated term involving the derivative of a hypergeometric function which can not be expressed in terms of elementary functions. We do our calculations in the Euclidean approach.

description: Structural mapping was completed on northwest Ellesmere Island to improve the understanding of the regional structures, as well as provide insight into the Eurekan Orogen as a whole. The Eurekan Orogen is a Paleogene-aged deformation event caused by the collision of Greenland with the Canadian Arctic. This deformation belt is present on Svalbard, Greenland and Ellesmere Island, and extends west into the Sverdrup Basin. On Ellesmere Island, Borup Fiord Pass is a north-south valley that cross-cuts east-west oriented Eurekan structures. A 50km north-south transect was mapped at 1:25,000 scale extending from Higgins Glacier to Mount Leith. The study area includes dextral strike slip faults and detachment folds, consistent with the deformation style on Northern Ellesmere Island, and the results support interpretations made by stratigraphic work completed in the area. These results are applied to the orientation of regional primary stresses, to solve irregular relationships within the orogeny. Conjugate fault systems on Ellesmere Island support westward movement of Central Ellesmere towards the Sverdrup Basin. A gravity-driven salt detachment model is suggested to explain the northerly trending Eurekan structures within the Sverdrup Basin.

subject: FOS: Mathematics

description: The method of derivative based global sensitivity measures (DGSM) has recently become popular among practitioners. It has a strong link with the Morris screening method and Sobol' sensitivity indices and has several advantages over them. DGSM are very easy to implement and evaluate numerically. The computational time required for numerical evaluation of DGSM is generally much lower than that for estimation of Sobol' sensitivity indices. This paper presents a survey of recent advances in DGSM concerning lower and upper bounds on the values of Sobol' total sensitivity indices $S\_{i}^{tot}$. Using these bounds it is possible in most cases to get a good practical estimation of the values of $S\_{i}^{tot} $. Several examples are used to illustrate an application of DGSM.
Death Reflection and Life-Meaning Construction
Creators: name: Hu, Chao S.
Publisher: name: OSF Registries
Year: 2023
Subjects: subject: Social and Behavioral Sciences

description: Localized Study of Death Reflection and Life-Meaning Construction Death reflection is an important process in the construction of life meaning. Death not only involves the destruction of the individual and thus fear but also the separation of interpersonal relationships and, thus, sadness. Based on this, the applicant proposes a sorrow management theory more suitable for Chinese people than the Terror management theory. It was found that when sadness dominates, reflecting on death makes Chinese people pay more attention to their inner life goals. Terror management involves the defense of one's worldview and cultural values, while wise reasoning requires overcoming self-serving biases and gaining insight into the facts of life. Creating psychological distance from oneself can reduce self-serving biases and help individuals re-examine their existing beliefs, discover the limitations of their knowledge, and thus consider and integrate new information to make reasoning more comprehensive and flexible. The applicant found that a future-oriented temporal perspective is helpful for wise reasoning in interpersonal conflicts. Likewise, can reflecting on death from a self-distanced perspective enhance wise reasoning and thus sorrow management, improve inner life goals, and thereby promote the sense of meaning in life and reduce suicidal ideation among Chinese people? Experiment 1 will explore the effects of death reflection from different spatiotemporal perspectives (time perspective: present/future ✖ spatial perspective: involved/observing) on emotions and life goals. Experiment 2 will explore the moderating effect of individualistic values. Experiment 3 will explore the mediating effect of wise reasoning. Experiment 4 will compare the differences between reflecting on the inevitability (everyone will die) and unpredictability (may die at any time) of death. Experiment 5 will investigate the neural mechanisms. Experiment 6 will conduct a longitudinal study: Participants will engage in 7 days of expressive writing (15 minutes per day) to reflect on death from different perspectives and complete measurements of sense of meaning in life and suicidal ideation before the intervention and 1, 3, and 6 months after the intervention. This project aims to develop the Sorrow Management Theory further for life wisdom education and suicide prevention practices.

description: The purpose of this qualitative study is to open a window of articulation and understanding into the lived experience and meaning of spirituality in the lives of gay men who, in the past or present, identify as being members of the Anglican expression of Christianity. While over the last 50 years or so institutionalized religious institutions have been declining in their social influence and membership numbers, there has been an increase in interest and attention to spirituality. Institutional religious movements in the past have been nearly uniformly negative or condemnatory of individuals identifying as gay, lesbian, bisexual, or transgender (GLBT), and of same-gender sexual expressions. Recently, however, attitudes have been changing in some branches of Christianity. Within the worldwide Anglican Communion,and more particularly in the Anglican Church of Canada, official and unofficial voices have expressed positions along a continuum ranging from condemnatory to affirming of same-sex affection, desire, and relationships. This study’s aim is to shed light on how gay men with roots in this particular religious community live out their gay identity and how they experience and express spirituality in their lives. Participants (N = 14) took part in two interviews. The starting points for the second interview were the photographs they brought reflecting their experience of spirituality. Utilizing Interpretive Phenomenological Analysis (IPA), two interrelated principal lenses were identified through which participants created meaning about that experience. The first lens, Influences, identified the location of various influences impacting participants’ experiencing spirituality. The second lens, Interpretative Engaging, explored how participants sifted, sorted, and sewed together both negative and growthful experiencing of these influences as they created meaning about spirituality in their lives. Identifiable qualities characterizing these participants’ experiencing also emerged. These qualities were that spirituality was (a) relational, (b) intentional, (c) directional, and (d) transformational. Limitations of this research are discussed, along with identifying potentially fruitful avenues of future research. Implications particularly for counselling psychology are also identified, especially noting the rich potential in utilizing photographic images as tools expressing and exploring experiential areas of life when words themselves fall short.

description: We show that Delaunay triangulations and compressed quadtrees are equivalent structures. More precisely, we give two algorithms: the first computes a compressed quadtree for a planar point set, given the Delaunay triangulation; the second finds the Delaunay triangulation, given a compressed quadtree. Both algorithms run in deterministic linear time on a pointer machine. Our work builds on and extends previous results by Krznaric and Levcopolous and Buchin and Mulzer. Our main tool for the second algorithm is the well-separated pair decomposition(WSPD), a structure that has been used previously to find Euclidean minimum spanning trees in higher dimensions (Eppstein). We show that knowing the WSPD (and a quadtree) suffices to compute a planar Euclidean minimum spanning tree (EMST) in linear time. With the EMST at hand, we can find the Delaunay triangulation in linear time. As a corollary, we obtain deterministic versions of many previous algorithms related to Delaunay triangulations, such as splitting planar Delaunay triangulations, preprocessing imprecise points for faster Delaunay computation, and transdichotomous Delaunay triangulations.

description: The IL-8 luciferase reporter cell line, THP-G8 cells, used in the in vitro sensitization test, OECD442E, can respond to a variety of stimuli other than haptens, such as lipopolysaccharide (LPS), other bacterial toxins, and detergents. Considering these characteristics, we examined the ability of the IL-8 luciferase assay using THP-G8 cells to evaluate water pollution. We first stimulated THP-G8 cell with various Toll-like receptor (TLR) agonists and nucleotide-binding oligomerization domain-like receptor (NLR) agonists, and found that TLR1, 2, 4, 5, 6 agonists and NOD 1, 2 agonists significantly augmented IL-8 luciferase activity (IL8LA). Then, we examined the detection threshold of LPS by THP-G8 cells, and found it 0.4 EU/ml. Next, we examined whether THP-G8 cells can differently respond to a variety of sources of environmental water around Sendai, Japan and Manila, Philippine and whether there is a correlation between the IL8LA of different sources of water and their level of endotoxin assessed by the LAL assay. There was a clear trend that the IL8LA was lower in the upper stream and higher in the downstream in both Japan and Philippine. Moreover, there was a strong correlation between the IL8LA of the environmental water and its endotoxin level. Finally, using N-acetyl-L-cysteine, an antioxidant/radical scavenger, and polymyxin B that neutralizes endotoxin, we demonstrated that there was a difference in the suppressive effects by them between the water from Japan and that from Philippine. These data suggest the potential of the IL-8 luciferase assay for evaluating environmental water pollution both quantitatively and qualitatively.

description: Manganese (Mn), iron (Fe), and zinc (Zn) are essential for diverse processes in plants, but their availability is often limiting or excessive. Cation diffusion facilitator (CDF) proteins have been implicated in the allocation of those metals in plants, whereby most of our mechanistic understanding has been obtained in Arabidopsis. It is unclear to what extent this can be generalized to other dicots. We characterized all CDFs/metal tolerance proteins of sugar beet (Beta vulgaris spp. vulgaris), which is phylogenetically distant from Arabidopsis. Analysis of subcellular localization, substrate selectivities, and transcriptional regulation upon exposure to metal deficiencies and toxicities revealed unexpected deviations from their Arabidopsis counterparts. Localization and selectivity of some members were modulated by alternative splicing. Notably, unlike in Arabidopsis, Mn- and Zn-sequestrating members were not induced in Fe-deficient roots, pointing to differences in the Fe acquisition machinery. This was supported by low Zn and Mn accumulation under Fe deficiency and a strikingly increased Fe accumulation under Mn and Zn excess, coinciding with an induction of BvIRT1. High Zn load caused a massive upregulation of Zn-BvMTPs. The results suggest that the employment of the CDF toolbox is highly diverse amongst dicots, which questions the general applicability of metal homeostasis models derived from Arabidopsis.

description: The needs to assess robust performances for complex systems and to answer tighter regulatory processes (security, safety, environmental control, and health impacts, etc.) have led to the emergence of a new industrial simulation challenge: to take uncertainties into account when dealing with complex numerical simulation frameworks. Therefore, a generic methodology has emerged from the joint effort of several industrial companies and academic institutions. EDF R&D, Airbus Group and Phimeca Engineering started a collaboration at the beginning of 2005, joined by IMACS in 2014, for the development of an Open Source software platform dedicated to uncertainty propagation by probabilistic methods, named OpenTURNS for Open source Treatment of Uncertainty, Risk 'N Statistics. OpenTURNS addresses the specific industrial challenges attached to uncertainties, which are transparency, genericity, modularity and multi-accessibility. This paper focuses on OpenTURNS and presents its main features: openTURNS is an open source software under the LGPL license, that presents itself as a C++ library and a Python TUI, and which works under Linux and Windows environment. All the methodological tools are described in the different sections of this paper: uncertainty quantification, uncertainty propagation, sensitivity analysis and metamodeling. A section also explains the generic wrappers way to link openTURNS to any external code. The paper illustrates as much as possible the methodological tools on an educational example that simulates the height of a river and compares it to the height of a dyke that protects industrial facilities. At last, it gives an overview of the main developments planned for the next few years.
Development Of A Three-Dimensional Model For Ice Rubble Interactions On Conical Structures

description: Offshore structures in waters where ice cover is prevalent from four to nine months a year have been constructed for the last 30 years to extract natural resources and to transport people and goods. Many of these structures are conical or sloped faced in shape, where flexural failure becomes the dominant mode of failure for the ice sheet. This reduces the magnitude of ice structure interaction loads in comparison to other modes of failure. In this particular study, ice interactions with the piers of the Confederation Bridge were examined. Since the 13 km bridge, spanning across the Northumberland Strait between the eastern Canadian provinces of Prince Edward Island and New Brunswick, opened in 1997, the Confederation Bridge Monitoring Program has been instituted to monitor ice interactions with the piers through the installation of video cameras, load sensors, and deformation sensors. Through 15 years of the Monitoring Program, archived video footage have shown that the highest interaction loads recorded on the piers are a result of ice rubble piles sitting on a level ice sheet and on the pier surface as the level ice sheet continues to fail in flexure. Various researchers have devised flexural failure models for ice and conical structure interactions. Each model shares the same principle of the ice sheet being modelled as a beam on an elastic foundation and each has different limitations in precisely predicting interaction loads. Some models do not incorporate the rubble pile, while other models make over simplified assumptions for three-dimensional behaviour. The proposed three-dimensional finite element model aims to reduce some of these limitations through: modelling the bilinear-shape ice rubble piles with a more rigorous slope stability method, modelling the geometry of the rubble around the cone through small-scale tests, adding a driving force in keeping the rubble pile intact during the interaction, and accounting for eccentric offsetting moments during ice-structure contact. Ten full-scale interaction events were chosen to validate the proposed model. Results of the model indicate good predictions of interaction loads for ice and conical structures.

description: This paper studies multi-user wireless powered communication networks, where energy constrained users charge their energy storages by scavenging energy of the radio frequency signals radiated from a hybrid access point (H-AP). The energy is then utilized for the users' uplink information transmission to the H-AP in time division multiple access mode. In this system, we aim to maximize the uplink sum rate performance by jointly optimizing energy and time resource allocation for multiple users in both infinite capacity and finite capacity energy storage cases. First, when the users are equipped with the infinite capacity energy storages, we derive the optimal downlink energy transmission policy at the H-AP. Based on this result, analytical resource allocation solutions are obtained. Next, we propose the optimal energy and time allocation algorithm for the case where each user has finite capacity energy storage. Simulation results confirm that the proposed algorithms offer 30% average sum rate performance gain over conventional schemes.
