Wave slamming on a horizontal plate
Creators: name: Bhat, Shankar Subraya
Publisher: name: University of British Columbia
Year: 2009

description: The design of coastal and offshore structures requires a thorough understanding of environmental loading, particularly due to waves. Structural elements such as decks located in the splash zone encounter intermittent contact with the water, and the loads associated with the water impact may be several times larger than those experienced by elements when fully submerged. These forces may give rise to localized damage and to fatigue problems. Such structures should clearly be designed to account for wave impact, in addition to more general wave loading. Several studies have reported the related problems of ship bottom slamming, missile entry and sea plane landing. Although previous studies have contributed to an improved understanding of wave impact, there is still considerable uncertainty in the estimation of impact loads on structural elements near the water surface. In this context, the present study has been carried out to examine the wave loads on a fixed horizontal plate located near the still water level. Experiments were conducted in the wave flume of the Hydraulics Laboratory of the Department of Civil Engineering at the University of British Columbia. A plate, 60.0 cm long, 20.0 cm wide and 6.25 mm thick, was instrumented with load-cells to measure the vertical force on the plate due to waves. The plate was supported by two vertical rods through the load-cells which were connected to a cross shaft mounted on bearings at the ends. Tests were conducted over a range of wave periods and wave heights in combination with different plate clearances above the still water level. The vertical reactions at the two supports were measured, and the time histories of vertical force and its line of action are thereby obtained. The wave surface elevations at the leading and rear end of the plate were measured with the plate absent. Results are presented in the form of force time histories, their lines of action and the associated water surface elevation. An analysis of these time histories is carried out to obtain various parameters of wave impact which include, the peak upward and downward force, their lines of action and times of occurrence, and the associated wetted lengths. The influence of incident wave parameters on these is investigated. Video images are studied to understand the impact process and to identify the difficulties involved in the investigation. An attempt is also made to predict the vertical force based on the hydrodynamic impact, drag and buoyancy forces.

description: An auto-Bäcklund transformation for the quad equation $\mathrm{Q1}_1$ is considered as a discrete equation, called $\mathrm{H2}^a$, which is a so called torqued version of $\mathrm{H2}$. The equations $\mathrm{H2}^a$ and $\mathrm{Q1}_1$ compose a consistent cube, from which a auto-Bäcklund transformation and a Lax pair for $\mathrm{H2}^a$ are obtained. More generally it is shown that auto-Bäcklund transformations admit auto-Bäcklund transformations. Using the auto-Bäcklund transformation for $\mathrm{H2}^a$ we derive a seed solution and a one-soliton solution. From this solution it is seen that $\mathrm{H2}^a$ is a semi-autonomous lattice equation, as the spacing parameter $q$ depends on $m$ but it disappears from the plain wave factor.

description: The United States subsidized 50 percent of its wheat exports between 1985 and 1988 under the Export Enhancement Program (EEP) in an attempt to expand U.S. exports and counter European Community export subsidies. The Department of Agriculture uses a complex bidding process to award EEP subsidies to targeted countries. The program grew steadily from 1985 through mid-1988, with wheat accounting for over 80 percent of EEP sales value. Economic analysis indicates that the program raised U.S. wheat export volume, prices, and gross export revenues. But net export revenues rose only slightly once the value of commodities from Government inventories awarded to exporters under the EEP is taken into account.
A study of bridge coating maintenance
Creators: name: Tam, Chun Kwok
Publisher: name: University of British Columbia
Year: 2009

description: Two analysis methods are presented in this thesis to minimize the cost of coating maintenance for steel bridges. The first method is incorporated into the Bridge Corrosion Cost Model. This model performs a life-cycle cost analysis using equivalent annual costs to compare the three maintenance strategies: spot repair, overcoat, and recoat. The strategy that provides the minimum equivalent annual cost is considered to be optimal. A computer application has been developed to reduce the work required to implement the procedures described in this model. The flexibility of this program allows the user to adjust key parameters in order to account for variability in costs and environmental conditions between different regions in British Columbia. In addition, an on-line help feature is provided to reduce the time needed to operate this program. The second method presented in this thesis uses the dynamic programming approach. The procedures are implemented into the Bridge Coating Maintenance Model. In this model, the sum of the costs resulting from a sequence of rehabilitation choices is rninimized. The procedures developed in this analysis can easily be converted into algorithms for possible computer applications. On the basis of the preliminary analysis using these two approaches, spot repair is the most cost effective rehabilitation method. Overcoating is the second most effective strategy and recoating is usually the most expensive solution. However, the difficulty in obtaining adequate deterioration and cost functions for the coating systems will significantly reduce the accuracy of these analysis techniques. Therefore, a uniform data collection system should be implemented so that a database will be available for these models.

description: The effects of heavy quarks energy loss on the transverse momentum spectra of single muons are studied. The energy loss of heavy quarks when traversing the medium formed in PbPb collisions at $\sqrt{s_\mathrm{NN}}$=5.5 TeV is calculated by implementing the collision geometry and the quenching weights. The medium density is assumed to decrease at forward pseudo-rapidity and to be proportional with pseudo-rapidity multiplicity $dN/dη$. Muons from W decays can be used as a medium-blind reference to quantify the effect of heavy quarks energy loss on the single muon production.

description: We construct a covariant formulation of the heterotic superstring on K3 times T^2 with manifest N=2 supersymmetry. We show how projective superspace appears naturally in the hybrid formulation giving a (partially) geometric interpretation of the harmonic parameter. The low-energy effective action for this theory is given by a non-standard form of N=2 supergravity which is intimately related to the N=1 old-minimal formulation. This formalism can be used to derive new descriptions of interacting projective superspace field theories using Berkovits' open string field theory and the the heterotic Berkovits-Okawa-Zwiebach construction.

description: People who write code for research are few and far between in the archaeological sciences. Quite often they are regarded as technicians and their function in research projects reduced to those of “helpers”, diminishing their contribution to the success of the undertaking. Nowadays some students of the humanities are trained in digital technologies to bridge the information gap between the different fields (Digital Humanities, DH). A similar situation can be found in Digital and Computational Archaeology, though the two disciplines only marginally influenced each other (Hugget 10.12759/hsr.37.2012.3.86-105). Some centers of Digital Archaeology work closely with DH departments and some DH specialists moved from archaeology to the broader field of DH, which shows that the job market in Digital Archaeology does not offer enough possibilities. The temporary nature of research related projects is another reason for an unstable job market in the field. To mitigate the effects of this instability, increased workload, surveillance and underappreciation, Hugget calls for a resilient scholarship in a digital age (Hugget 10.5334/jcaa.25). One important aspect he names on the individual level is forming a community for networking and support. We will present the “Research Squirrel Engineers”, an open, diverse and international network, which aims at RSEs connecting and developing their own ideas for side projects independent from institutions (and funding). Within the Research Squirrel community, currently two members have an engineering background (computer science, geoinformatics) whereas the other two studied a humanities subject (archaeology). By focusing on their own research interests they help RSEs to retain joy in their job, diversify and showcase their skill sets. So far Squirrels focus on (Linked) Open Data projects, but are happy to receive suggestions and new research squirrels joining at SORSE.

Για να το πετύχουμε, χρησιμοποιούμε διαθέσιμα RNA-seq δεδομένα Σιδερίτη. Ωστόσο, ο αριθμός των διαθέσιμων δειγμάτων (σύνολα γονιδιακών μετρήσεων) που διαθέτουμε μέχρι στιγμής δεν επιτρέπει την εφαρμογή υπαρχόντων στατιστικών μεθόδων.

Με αυτόν τον τρόπο, αυξάνουμε το πλήθος των διαθέσιμων φυτών και δημιουργούμε ένα νέο τεχνητό γένος ώστε να πετύχουμε τα (α) και (β) αντίστοιχα. Στη συνέχεια εξετάζουμε διάφορες μεθόδους επιλογής χαρακτηριστικών βασιζόμενοι σε τυχαία δάση για να επιλέξουμε τα πιο σημαντικά γονίδια (δηλαδή αυτά που περικλείουν τις διαφορές μεταξύ ειδών ή μεταξύ γενών). Χρησιμοποιούμε τυχαία δάση για να αξιολογήσουμε τις προτεινόμενες μεθόδους παραγωγής δεδομένων και επιλογής γονιδίων, καθώς είναι ευρέως αποδεκτά ως μια από τις καταλληλότερες μεθόδους ταξινόμησης γενομικών δεδομένων. Τέλος, ερευνούμε την επίδραση των επιλεγμένων υποσυνόλων γονιδίων στην αναγνώριση ειδών και γενών και παρουσιάζουμε τα αντίστοιχα γονιδιακά προϊόντα
description: In this work, we attempt to identify: a) the most important genes that differentiate between three species of Sideritis: Scardica, Syriaca and Athoa and b) those genes that characterize the entire genus. To do so, we use available Sideritis RNA-seq data. However, the number of currently available samples (i.e. sets of gene measurements) does not permit proceeding with sophisticated statistical methods. To this end, we propose and compare several novel methods for simulated data generation. This way, we increase the number of available plants and create a new simulated genus, to address (a) and (b) respectively. We then explore various feature selection methods based on random forests, aiming to select the most important genes (i.e. those encapsulating the differences between species or between genera). We use random forests to evaluate methods proposed for data generation and gene selection, since they are generally accepted as one of the most suitable methods for genomic data classification. Finally, we investigate the impact of the selected gene subsets on species and genera recognition and present related gene products

description: Prognostication of vehicle trajectories in unknown environments is intrinsically a challenging and difficult problem to solve. The behavior of such vehicles is highly influenced by surrounding traffic, road conditions, and rogue participants present in the environment. Moreover, the presence of pedestrians, traffic lights, stop signs, etc., makes it much harder to infer the behavior of various traffic agents. This paper attempts to solve the problem of Spatio-temporal look-ahead trajectory prediction using a novel recurrent neural network called the Memory Neuron Network. The Memory Neuron Network (MNN) attempts to capture the input-output relationship between the past positions and the future positions of the traffic agents. The proposed model is computationally less intensive and has a simple architecture as compared to other deep learning models that utilize LSTMs and GRUs. It is then evaluated on the publicly available NGSIM dataset and its performance is compared with several state-of-art algorithms. Additionally, the performance is also evaluated on a custom synthetic dataset generated from the CARLA simulator. It is seen that the proposed model outperforms the existing state-of-art algorithms. Finally, the model is integrated with the CARLA simulator to test its robustness in real-time traffic scenarios.

description: Epitaxial self-assembled quantum dots (SAQDs) represent an important step in the advancement of semiconductor fabrication at the nanoscale that will allow breakthroughs in electronics and optoelectronics. In these applications, order is a key factor. Here, the role of crystal anisotropy in promoting order during early stages of SAQD formation is studied through a linear analysis of a commonly used surface evolution model. Elastic anisotropy is used a specific example. It is found that there are two relevant and predictable correlation lengths. One of them is related to crystal anisotropy and is crucial for determining SAQD order. Furthermore, if a wetting potential is included in the model, it is found that SAQD order is enhanced when the deposited film is allowed to evolve at heights near the critical surface height for three-dimensional film growth.

description: Bipartite networks are a useful tool for representing and investigating interaction networks. We consider methods for identifying communities in bipartite networks. Intuitive notions of network community groups are made explicit using Newman's modularity measure. A specialized version of the modularity, adapted to be appropriate for bipartite networks, is presented; a corresponding algorithm is described for identifying community groups through maximizing this measure. The algorithm is applied to networks derived from the EU Framework Programs on Research and Technological Development. Community groups identified are compared using information-theoretic methods.

description: In Transport Mode Detection, a great diversity of methodologies exist according to the choice made on sensors, preprocessing, model used, etc. In this domain, the comparisons between each option are not always complete. Experiments on a public, real-life dataset are led here to evaluate carefully each of the choices that were made, with a specific emphasis on data fusion methods. Our most surprising finding is that none of the methods we implemented from the literature is better than a simple late fusion. Two important decisions are the choice of a sensor and the choice of a representation for the data: we found that using 2D convolutions on spectrograms with a logarithmic axis for the frequencies was better than 1-dimensional temporal representations.

description: We test whether or not the tau lepton manifests the same couplings as the mu lepton by investigating the relative decay rates in purely leptonic D+ meson decays. Specifically, we place the first upper limit on the ratio R=Gamma(D+ -> tau+ nu)/Gamma(D+ -> mu+ nu). We use 281 inverse pb of data accumulated at the psi(3770) resonance with the CLEO-c detector, to determine B(D+ -> tau+ nu) < 2.1 x 10^(-3) at 90% confidence level (C. L.). The ratio of R to the Standard Model expectation of 2.65 then is <1.8 at 90% C. L., consistent with the prediction of lepton universality.

description: Improved irrigation technology and advanced farm management practices offer an opportunity for agriculture to use water more efficiently. Farmers may install new equipment, such as drip irrigation systems, or adopt advanced water management practices to conserve water without sacrificing crop yields. While farmers' decision to adopt water-saving irrigation technology responds to the cost of water, physical properties of the land such as topography or soil texture dominate the choice of irrigation technology.

Οι συμμετέχοντες έπαιξαν το παιχνίδι 2 φορές, υπό τους ήχους 2 διαφορετικών μουσικών backgrounds επιλεγμένα ώστε να προκαλούν διαφορετικά συναισθήματα στον παίκτη, το ένα θυμό και το άλλο νοσταλγία. Εξετάστηκε αν το συναίσθημα επηρεάζει το χρόνο αντίδρασης, άρα το χρόνο λήψης μιας απόφασης ηθικής συνείδησης, κάτι που όντως βρέθηκε να συμβαίνει τόσο στους άντρες όσο και στις γυναίκες συμμετέχοντες. Αυτό συνέβη στις περιπτώσεις που χτυπούσαν άντρες και μακρινούς στόχους. Δεν βρέθηκαν διαφορές φύλου στις επιλογές και τους μέσους όρους των χρόνων αντίδρασης. Οι συμμετέχοντες επέλεξαν να πυροβολήσουν άντρες και όχι γυναίκες στόχους, όμως είχαν μεγαλύτερο δισταγμό να χτυπήσουν τους άντρες από ό,τι τις γυναίκες. Επίσης, επέλεξαν κοντινούς και όχι μακρινούς στόχους, τους οποίους δίσταζαν λιγότερο να χτυπήσουν
description: In the present paper a theoretical analysis was done about consciousness and the matter of existence of free will. After that, the issue of moral consciousness was analyzed. The experiment was designed to study these two issues combined. A shoot them up video game was created, in which the targets were videotaped humans, standing at close or far distances. The goal was to study the decisions and the reaction time of the players, as the criteria of hesitation towards certain targets could function as a possible indicator of moral conflict. Each player played the game twice, listening to 2 different musical backgrounds, chosen to cause different emotions, anger for the first condition and nostalgia for the second. Whether emotion has an impact on reaction times and thus on the process of making the moral decisions was examined. This actually happened for both male and female players when they shot male and far situated targets. There were no gender differences when it came to the decision of which target to shoot or the reaction times. The players chose male over female targets, but they hesitated more to shoot male targets. They chose close over far situated targets and they hesitated more to shoot the far ones

description: We present a quantum Monte Carlo method with exact projection on parity and angular momentum that is free of sign-problems for seniority-conserving nuclear interactions. This technique allows a microscopic calculation of angular momentum and parity projected nuclear level densities. We present results for the $^{55}$Fe, $^{56}$Fe and $^{57}$Fe isotopes. Signatures of the pairing phase transition are observed in the angular momentum distribution of the nuclear level density.

description: We analyze the memory in volatility by studying volatility return intervals, defined as the time between two consecutive fluctuations larger than a given threshold, in time periods following stock market crashes. Such an aftercrash period is characterized by the Omori law, which describes the decay in the rate of aftershocks of a given size with time t by a power law with exponent close to 1. A shock followed by such a power law decay in the rate is here called Omori process. Studying several aftercrash time series, we show that the Omori law holds not only after significant market crashes, but also after ``intermediate shocks''. Moreover, we find self-similar features in the volatility. Specifically, within the aftercrash period there are smaller shocks that themselves constitute Omori processes on smaller scales, similar to the Omori process after the large crash. We call these smaller shocks subcrashes, which are followed by their own aftershocks. We also find similar Omori processes after intermediate crashes in time regimes without a large market crash. By appropriate detrending we remove the influence of the crashes and subcrashes from the data, and find that this procedure significantly reduces the memory in the records. Our results are consistent with the hypothesis that the memory in volatility is related to Omori processes present on different time scales.

description: As novel applications spring up in future network scenarios, the requirements on network service capabilities for differentiated services or burst services are diverse. Aiming at the research of collaborative computing and resource allocation in edge scenarios, migrating computing tasks to the edge and cloud for computing requires a comprehensive consideration of energy consumption, bandwidth, and delay. Our paper proposes a collaboration mechanism based on computation offloading, which is flexible and customizable to meet the diversified requirements of differentiated networks. This mechanism handles the terminal's differentiated computing tasks by establishing a collaborative computation offloading model between the cloud server and edge server. Experiments show that our method has more significant improvements over regular optimization algorithms, including reducing the execution time of computing tasks, improving the utilization of server resources, and decreasing the terminal's energy consumption.

description: The low energy scattering of gravitons from a composite extended system, which is made of classical massive bodies, is considered; by using the Feynman rules of effective quantum gravity, the corresponding cross-section is computed to lowest order in powers of the gravitational coupling constant. For the gravitons scattering from a rotating planet or a star, it is shown that the classical limit of the matter-gravitons coupling in the effective quantum gravity lagrangian leads to a low energy scattering amplitude which coincides with the expression obtained in classical general relativity.

description: Η ανάγκη προστασίας των προσωπικών δεδομένων αποτελεί τον συνηθέστερο λόγο που επικαλείται η Διοίκηση για την απόρριψη των αιτήσεων παροχής πρόσβασης στα έγγραφα που κατέχει. Σε πολλές περιπτώσεις η επίκληση είναι καταχρηστική, στοχεύοντας στην ελάφρυνση του φόρτου εργασίας του Δημοσίου εις βάρος της Διαφάνειας, συνήθως όμως αποτελεί συνέπεια της αδυναμίας των διοικητικών αρχών να εφαρμόσουν τις αντιφατικές και αλληλοσυγκρουόμενες διατάξεις που διέπουν την πρόσβαση στα δημόσια έγγραφα με προσωπικά δεδομένα. Η ίδια προβληματική εμφανίζεται και στο ενωσιακό δίκαιο όπου ελλείψει ενός συνεκτικού θεσμικού πλαισίου, το βάρος της εξισορρόπησης των διακυβευόμενων δικαιωμάτων μετακυλίεται στα θεσμικά όργανα. Η μελέτη διερευνά το δίπολο προστασία δεδομένων - πρόσβαση στην πληροφορία, στην ελληνική και ενωσιακή έννομη τάξη, εξετάζει τα προβλήματα που δημιουργεί στην πράξη η διασταύρωση των δύο δικαιωμάτων και εκθέτει τις λύσεις που έχουν προταθεί στη θεωρία και τη νομολογία για την υπέρβαση των αναφυόμενων συγκρούσεων. Τα de lege lata κριτήρια ορθής συνεφαρμογής των δύο δικαιωμάτων ακολουθούν de lege ferenda προτάσεις αναθεώρησης του θεσμικού πλαισίου προς μια κατεύθυνση που θα περιορίζει τις στρεβλώσεις και θα ενισχύει την ασφάλεια δικαίου
description: The need to safeguard personal data is the most common reason invoked by Public Administration for refusal of access to documents. Data protection is in many cases invoked abusively, aiming to lighten administrative workload to the detriment of transparency. Yet, most often this is a consequence of public authorities’ inability to implement the inherently inconsistent and contradictory provisions governing public access to documents which contain personal data. The same problem preoccupies European Law, where achieving a right balance between the rights at stake is passed on to the Union’s institutions in the absence of a coherent institutional framework. This dissertation explores the relationship between data protection and access to documents in Greek and European legal order, examines the problems arising in practice from the conflicting interests and illustrates solutions proposed in doctrine and jurisprudence. It also proposes criteria for the proper balancing of rights and suggests de lege ferenda changes to existing legislation toward limiting distortions and enhancing legal certainty

description: Machine learning (ML) has been used to develop increasingly accurate link quality estimators for wireless networks. However, more in-depth questions regarding the most suitable class of models, most suitable metrics and model performance on imbalanced datasets remain open. In this paper, we propose a new tree-based link quality classifier that meets high performance and fairly classifies the minority class and, at the same time, incurs low training cost. We compare the tree-based model, to a multilayer perceptron (MLP) non-linear model and two linear models, namely logistic regression (LR) and SVM, on a selected imbalanced dataset and evaluate their results using five different performance metrics. Our study shows that 1) non-linear models perform slightly better than linear models in general, 2) the proposed non-linear tree-based model yields the best performance trade-off considering F1, training time and fairness, 3) single metric aggregated evaluations based only on accuracy can hide poor, unfair performance especially on minority classes, and 4) it is possible to improve the performance on minority classes, by over 40% through feature selection and by over 20% through resampling, therefore leading to fairer classification results.

description: A basic problem associated with the development of new techniques in the fields of computer animation, robotics, and simulation is that many researchers utilize dissimilar constructs to represent common structures. Attempts to combine various models into one coherent system can often be painstakingly difficult. This forces the users to expend valuable time re-inventing previously written code. To resolve this problem, this thesis presents the RASP (Robotic and Animation Simulation Platform) toolkit - an extensible collection of primitives, functions, and essential abstractions for the creation of reusable time-varying simulations. Based on object-oriented principles, modern patterns of communications, and various simulation techniques, the toolkit defines a common architecture and set of conventions for researchers to follow when developing simulations. Through these building blocks, users will be able to borrow, without considerable need for modifications, code segments and tools from previously developed RASP projects. The RASP toolkit is highlighted by the following set of features: (a) IMVCD - a framework for the construction of time-varying systems; (b) Connection Paradigm - a "port"-based approach to data communication; (c) Hierarchical Temporal Modeling - a top down approach to temporal management based upon multiple world views and first-class temporal primitives; and (d) Hybrid Object Construction - a clear design for the development and visualization of complex objects.

description: Light trapping is a constant pursuit in photonics because of its importance in science and technology. Many mechanisms have been explored, including the use of mirrors made of materials or structures that forbid outgoing waves, and bound states in the continuum that are mirror-less but based on topology. Here we report a compound method, combing mirrors and bound states in the continuum in an optimized way, to achieve a class of on-chip optical cavities that have high quality factors and small modal volumes. Specifically, light is trapped in the transverse direction by the photonic band gap of the lateral hetero-structure and confined in the vertical direction by the constellation of multiple bound states in the continuum. As a result, unlike most bound states in the continuum found in photonic crystal slabs that are de-localized Bloch modes, we achieve light-trapping in all three dimensions and experimentally demonstrate quality factors as high as $Q = 1.09 \times 10^6$ and modal volumes as low as $V = 3.56~ μm^3$ in the telecommunication regime. We further prove the robustness of our method through the statistical study of multiple fabricated devices. Our work provides a new method of light trapping, which can find potential applications in photonic integration, nonlinear optics and quantum computing.

description: Higgs boson production in association with two forward jets and a central photon at the CERN Large Hadron Collider is analyzed, for the Higgs boson decaying into a b bbar pair in the m_H <= 140 GeV mass region. We study both irreducible and main reducible backgrounds at parton level. Compared to the Higgs production via vector-boson fusion, the request of a further photon at moderate rapidities dramatically enhances the signal/background ratio. Inclusive cross sections for p_T^γ>= 20 GeV can reach a few tens of fb's. After a suitable choice of kinematical cuts, the cross-section ratio for signal and irreducible-background can be enhanced up to >= ~1/10, with a signal cross section of the order of a few fb's, for m_H ~ 120 GeV. The request of a central photon radiation also enhances the relative signal sensitivity to the WWH coupling with respect to the ZZH coupling. Hence, a determination of the cross section for the associated production of a Higgs boson decaying into a b bbar pair plus a central photon in vector-boson fusion could help in constraining the b bbar H coupling, and the WWH coupling as well. A preliminary study of QCD showering effects points to a further significant improvement of the signal detectability over the background.
