description: In many safety-critical control systems, possibly opposing safety restrictions and control performance objectives arise. To confront such a conflict, this letter proposes a novel methodology that embeds safety into stability of control systems. The development enforces safety by means of barrier functions used in optimization through the construction of barrier states (BaS) which are embedded in the control system's model. As a result, as long as the equilibrium point of interest of the closed loop system is asymptotically stable, the generated trajectories are guaranteed to be safe. Consequently, a conflict between control objectives and safety constraints is substantially avoided. To show the efficacy of the proposed technique, we employ barrier states with the simple pole placement method to design safe linear controls. Nonlinear optimal control is subsequently employed to fulfill safety, stability and performance objectives by solving the associated Hamilton-Jacobi-Bellman (HJB) which minimizes a cost functional that can involve the BaS. Following this further, we exploit optimal control with barrier states on an unstable, constrained second dimensional pendulum on a cart model that is desired to avoid low velocities regions where the system may exhibit some controllability loss and on two mobile robots to safely arrive to opposite targets with an obstacle on the way.

description: High performance but unverified controllers, e.g., artificial intelligence-based (a.k.a. AI-based) controllers, are widely employed in cyber-physical systems (CPSs) to accomplish complex control missions. However, guaranteeing the safety and reliability of CPSs with this kind of controllers is currently very challenging, which is of vital importance in many real-life safety-critical applications. To cope with this difficulty, we propose in this work a Safe-visor architecture for sandboxing unverified controllers in CPSs operating in noisy environments (a.k.a. stochastic CPSs). The proposed architecture contains a history-based supervisor, which checks inputs from the unverified controller and makes a compromise between functionality and safety of the system, and a safety advisor that provides fallback when the unverified controller endangers the safety of the system. Both the history-based supervisor and the safety advisor are designed based on an approximate probabilistic relation between the original system and its finite abstraction. By employing this architecture, we provide formal probabilistic guarantees on preserving the safety specifications expressed by accepting languages of deterministic finite automata (DFA). Meanwhile, the unverified controllers can still be employed in the control loop even though they are not reliable. We demonstrate the effectiveness of our proposed results by applying them to two (physical) case studies.

description: This is the second paper by Nordstr{ö}m on his five dimensional theory. It aims at generalizing the relations $\mathbf{D} = ε\mathbf{E}$, $\mathbf{B} = μ\mathbf{H}$ of electromagnetism to the five dimensional gravito-electric theory and to show that this is consistent with the principle of equivalence. Some steps are taken toward providing a foundation for a theory of matter. Nordstr{ö}m hopes, as stated in the conclusion, to show ''that the five dimensional perspective, while still having only a formal content, may however provide footholds for further developments of the theory of gravitation, which otherwise would have been hard to find''.

In der Bevölkerung hingegen genießt das Gericht seit jeher ein besonders hohes Vertrauen. Ihm wird die Sachkompetenz zugesprochen, das Verfassungsrecht politisch neutral zu schützen und zeitgemäß auszulegen. Wo aber liegen die kompetenziellen Grenzen zwischen Gericht und Gesetzgeber?

description: Education for Sustainable Development (ESD) is recognized as one of the most important tools for achieving sustainability through cultivating new environmental culture and knowledge, skills, values and attitudes. An important ecological concept, which is considered one of the principles of sustainability is the concept of carrying capacity. It describes the pressure that organizations exert on their surroundings in an attempt to meet their needs for food, housing, water, etc. How the conceptual framework of carrying capacity meets the principles and objectives of Education for Sustainable Development? How could it contribute in teaching Sustainability? This thesis attempts to investigate the contribution of the conceptual framework of the ecological concept of "carrying capacity" (characteristics, principles, philosophy) in forming an educational tool for sustainability in an Education Environment for Sustainable Development.

The implementation of Ontario pay equity legislation
Creators: name: Strom, Arlene J.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is a case study of the implementation of Ontario's 1987 pay equity legislation. Ontario's pay equity legislation was very progressive and was aimed at eliminating the portion of the wage gap between men and women caused by discrimination. The legislation mandated both public and private sector employers with more than 10 employees to create pay equity plans to eliminate the discriminatory portion of the wage gap. The legislation has met with some success. However, measuring the progress of eliminating wage discrimination is difficult because the Ontario government was unwilling to impose a coercive implementation regime. Consequently, the government has little information to measure either employer compliance or the results of employer pay equity plans. Employers have few incentives to comply with the legislation and the implementing agency has insufficient financial resources to monitor compliance. Clearly this implementation regime was a delicate political balancing of the interests of business and labour and women.

description: Genus Ornithogalum is mostly described as morphologically variable („execrable“) genus, without clear morphological distinction among species. What is noticeable in Ornithogalum – is low number of distinctive qualitative morphological characteristics, in the first place among closely related species. Seed texture was nominated as species specific characteristic, but the latest research refuted that. The flower has the most quantitative characteristics and using morphometric analysis Ornithogalum s.s. species can be differentiated. To present flower differences of eight Ornithogalum species (O. comosum, O. montanum, O. dalmaticum, O kochii, O. umbellatum, O divergens, O sibthorpii, O. refractum), in total 21 characteristics were analysed. Parameters of flower length (perigon length) were correlated with scape, inflorescence and pedicel length, with an aim to merge these characteristics for plant determination key. Ornithogalum comosum and O. montanum were separated as species with „small“ flowers, while O. kochii has medium size flowers. All other investigated species have „large“ flowers. Different combinations of analysed flower characteristics allow species discrimination to some extent. For some species, however, additional characteristics (as scape, inflorescene and pedicel length) are needed for correct plant identification.

description: Beyond the conventional trial-and-error method, machine learning offers a great opportunity to accelerate the discovery of functional materials, but still often suffers from difficulties such as limited materials data and unbalanced distribution of target property. Here, we propose the ab initio Bayesian active learning method that combines active learning and high-throughput ab initio calculations to accelerate prediction of desired functional materials with the ultrahigh efficiency and accuracy. We apply it as an instance to a large family (3,119) of two-dimensional hexagonal binary compounds with unbalanced materials property, and accurately screen out the materials with maximal electric polarization and proper photovoltaic band gaps, respectively, whereas the computational costs are significantly reduced by only calculating a few tenths of possible candidates in comparison to the random search. This approach shows enormous advantages for the cases with unbalanced distributions of target property. It can be readily applied to seek for a broad range of advanced materials.

description: The natural interpretation of deep inelastic scattering is in terms of hard scattering on QCD constituents of the target. We examine the relation between amplitudes measured in exclusive lepto-production and the quark content of the nucleon. We show that in the Bjorken limit, the natural interpretation of amplitudes measured in these hard exclusive processes is in terms of the quark content of the meson cloud and not the target itself. Therefore the most efficient representation of these exclusive processes is in terms of leading Regge amplitudes.

description: In this dissertation we studied the problem of predictive learning and more specifically the problem of predicting multiple attributes at once. We mostly focused on regression, where the output variables are numeric. At first, we present some known regression and multi-target regression techniques and also the metrics that can be used for evaluating regression models. The next chapters include a presentation of a proposed method for multi-target regression. This method transforms the multi-target problem into a single-target one, by making the assumption that the target attributes are correlated linearly and thus using random linear combinations of these target attributes during the transformation process. Finally it uses an ensemble of models of that kind to increase the predictive performance of the system. The goal of this technique is to take advantage of any information that can be provided from the fact that the output attributes may be related.

Επίσης, προτείνεται μία νέα μέθοδο διαστρωματωμένης δειγματοληψίας για δεδομένα πολλαπλών ετικετών που βασίζεται στο συνδυασμό προηγούμενων μεθόδων διαστρωματωμένης δειγματοληψίας. Πιο συγκεκριμένα, μελετήθηκαν δύο τεχνικές (αλγόριθμοι) διαστρωματωμένης δειγματοληψίας. Στην πρώτη, οι ομάδες παραδειγμάτων διαμορφώνονται με βάση τους διαφορετικούς συνδυασμούς των ετικετών (labelsets) που υπάρχουν στα παραδείγματα εκπαίδευσης. Στη δεύτερη, κάθε ετικέτα αντιμετωπίζεται ανεξάρτητα από τις άλλες διατηρώντας την κατανομή θετικών και αρνητικών παραδειγμάτων για κάθε ετικέτα. Οι δύο παραπάνω μέθοδοι τροποποιήθηκαν ώστε να δουλεύουν και για δημιουργία ομάδων με άνισα ποσοστά παραδειγμάτων. Τέλος, προτείνουμε μία νέα “υβριδική” μέθοδο διαστρωματωμένης δειγματοληψίας η οποία συνδυάζει τις δύο μεθόδους που αναφέρθηκαν παραπάνω. Το βασικό σκεπτικό είναι να διατηρηθούν οι αναλογίες των παραδειγμάτων ανά ετικέτα στις ομάδες που προκύπτουν. Αυτό επιτυγχάνεται εφαρμόζοντας αρχικά την πρώτη μέθοδο δειγματοληψίας και εφόσον ικανοποιούνται κάποιες συνθήκες εφαρμόζεται η δεύτερη μέθοδος.
description: This thesis has as objective the study of existing techniques for stratified sampling of multi-label data. Then, we propose a new method for stratified sampling of multi-label data which is based on a combination of the previous stratification methods. More specifically, we studied two techniques (algorithms) for stratified sampling. In the first technique, the groups of the examples are formed based on the different combinations of labels (labelsets) that exist in the training set. In the second technique, each label is treated independently of the other while maintaining the distribution of positive and negative examples for each label. These two methods have been modified to create groups of examples with unequal rates of examples. Finally, we propose a new "hybrid" stratification method which combines the two methods that are mentioned above. The basic idea is to maintain the proportions of examples per label in the groups that arise. This is accomplished applying, initially, the first stratification method and if certain conditions are satisfied, we apply the second stratification method.
Fuel-Economical Distributed Model Predictive Control for Heavy-Duty Truck Platoon

description: This paper proposes a fuel-economical distributed model predictive control design (Eco-DMPC) for a homogenous heavy-duty truck platoon. The proposed control strategy integrates a fuel-optimal control strategy for the leader truck with a distributed formation control for the following trucks in the heavy-duty truck platoon. The fuel-optimal control strategy is implemented by a nonlinear model predictive control (NMPC) design with an instantaneous fuel consumption model. The proposed fuel-optimal control strategy utilizes the preview information of the preceding traffic to achieve the fuel-economical speed planning by avoiding energy-inefficient maneuvers, particularly under transient traffic conditions. The distributed formation control is designed with a serial distributed model predictive control (DMPC) strategy with guaranteed local and string stability. In the DMPC strategy, each following truck acquires the future predicted state information of its predecessor through vehicle connectivity and then applies local optimal control to maintain constant spacing. Simulation studies are conducted to investigate the fuel economy performance of the proposed control strategy and to validate the local and string stability of the platoon under a realistic traffic scenario. Compared with a human-operated platoon and a benchmark formation-controlled platoon, the proposed Eco-DMPC significantly improves the fuel economy and road utilization.

description: It has been proposed that there are new degrees of freedom intrinsic to quantum critical points that contribute to quantum critical physics. We study 2+1 D antiferromagnets in order to explore possible new quantum critical physics arising from nontrivial topological effects. We show that skyrmion excitations are stable at criticality and have nonzero probability at arbitrarily low temperatures. To include quantum critical skyrmion effects, we find a class of exact solutions composed of skyrmion and antiskyrmion superpositions, which we call topolons. We include the topolons in the partition function and renormalize by integrating out small size topolons and short wavelength spin waves. We obtain a correlation length critical exponent nu=0.9297 and anomalous dimension eta=0.3381.

description: We develop a resource theory of symmetric distinguishability, the fundamental objects of which are elementary quantum information sources, i.e., sources that emit one of two possible quantum states with given prior probabilities. Such a source can be represented by a classical-quantum state of a composite system $XA$, corresponding to an ensemble of two quantum states, with $X$ being classical and $A$ being quantum. We study the resource theory for two different classes of free operations: $(i)$ ${\rm{CPTP}}_A$, which consists of quantum channels acting only on $A$, and $(ii)$ conditional doubly stochastic (CDS) maps acting on $XA$. We introduce the notion of symmetric distinguishability of an elementary source and prove that it is a monotone under both these classes of free operations. We study the tasks of distillation and dilution of symmetric distinguishability, both in the one-shot and asymptotic regimes. We prove that in the asymptotic regime, the optimal rate of converting one elementary source to another is equal to the ratio of their quantum Chernoff divergences, under both these classes of free operations. This imparts a new operational interpretation to the quantum Chernoff divergence. We also obtain interesting operational interpretations of the Thompson metric, in the context of the dilution of symmetric distinguishability.

description: This work studies the production of direct photons in relativistic nuclear collisions, along with the production of hadrons. Radiation from the very first instants to the final moments of the evolution is included. The hybrid model used here describes all stages of relativistic heavy-ion collisions. Chronologically, those are an initial state reflecting the collision of nuclei described within the Color Glass Condensate effective theory; a pre-equilibrium phase based on non-equilibrium linear response; relativistic viscous hydrodynamics, and a hadronic afterburner. The effect of the pre-equilibrium phase on both photonic and hadronic observables is highlighted for the first time. The potential of photon observables -- spectrum, differential elliptic and triangular flow -- to reveal the chemical equilibration time is studied. Finally, we consider "small collision systems", including proton+nucleus collisions and collisions of light nuclei, as probed by hadronic and electromagnetic observables. We demonstrate how photon production can signal the formation of quark-gluon plasma in such small systems.

description: Inspired by anomalies which the standard scattering matrix pole-extraction procedures have produced in a mathematically well defined coupled-channel model, we have developed a new method based solely on the assumption of partial-wave analyticity. The new method is simple and applicable not only to theoretical predictions but to the empirical partial-wave data as well. Since the standard pole-extraction procedures turn out to be the lowest-order term of the proposed method the anomalies are understood and resolved.

description: Two-dimensional (2D) magnets have broad application prospects in the spintronics, but how to effectively control them with a small electric field is still an issue. Here we propose that 2D magnets can be efficiently controlled in a multiferroic heterostructure composed of 2D magnetic material and perovskite oxide ferroelectric (POF) whose dielectric polarization is easily flipped under a small electric field. We illustrate the feasibility of such strategy in the bilayer CrI3/BiFeO3(001) heterostructure by using the first-principles calculations. Different from the traditional POF multiferroic heterostructures which have strong interface interactions, we find that the interface interaction between CrI3 and BiFeO3(001) is van der Waals type. Whereas, the heterostructure has particular strong magnetoelectric coupling where the bilayer CrI3 can be efficiently switched between ferromagnetic and antiferromagnetic types by the polarized states of BiFeO3(001). We also discover the competing effect between electron doping and the additional electric field on the interlayer exchange coupling interaction of CrI3, which is responsible to the magnetic phase transition. Our results provide a new avenue for the tuning of 2D magnets with a small electric field.

description: With its ability to look at bright galactic X-ray sources with sub-millisecond time resolution, the Rossi X-ray Timing Explorer (RXTE) discovered that the X-ray emission from accreting compact stars shows quasi-periodic oscillations on the dynamical timescales of the strong field region. RXTE showed also that waveform fitting of the oscillations resulting from hot spots at the surface of rapidly rotating neutron stars constrain their masses and radii. These two breakthroughs suddenly opened up a new window on fundamental physics, by providing new insights on strong gravity and dense matter. Building upon the RXTE legacy, in the Cosmic Vision exercise, testing General Relativity in the strong field limit and constraining the equation of state of dense matter were recognized recently as key goals to be pursued in the ESA science program for the years 2015-2025. This in turn identified the need for a large (10 m2 class) aperture X-ray observatory. In recognition of this need, the XEUS mission concept which has evolved into a single launch L2 formation flying mission will have a fast timing instrument in the focal plane. In this paper I will outline the unique science that will be addressed with fast X-ray timing on XEUS.

description: Статья освящает понятие корпоративной культуры, которое не нашло единого подхода среди исследователей. Корпоративная культура рассматривается как система ценностей и норм поведения на предприятии, обладающая определенной структурой. Она выполняет целый перечень важных функций и ставит своей целью повысить эффективность работы сотрудников и компании в целом. Корпоративная культура особым образом влияет на показатели организации, однако ее появление не всегда является результатом действий руководства. В конце приводятся основные ценности, составляющие КК западных компаний и обеспечившие их успех.The article sanctifies the concept of corporate culture, which has not found a unified approach among researchers. Corporate culture is considered as a system of values and norms of behavior in an enterprise with a certain structure. It performs a whole range of important functions and aims to improve the efficiency of employees and the company. Corporate culture in a special way affects the performance of the organization, but its appearance is not always the result of management actions. At the end, the basic values that constitute the QC of Western companies and ensure their success are given.

description: В статье рассматривается целесообразность создания региональных саморегулируемых организаций в агропромышленном комплексе Пермского края. Сельское хозяйство региона в большей степени ориентировано на развитие отрасли животноводства. Создание СРО АПК Пермского края, в состав которого будут входить сельскохозяйственные организации, крестьянско-фермерские хозяйства, индивидуальные предприниматели, позволит решать не только вопросы производственной и финансово-экономической деятельности членов СРО, но и формировать кадровый потенциал и управлять человеческими ресурсами хозяйствующих субъектов.The article considers the feasibility of creating regional self-regulatory organizations in the agricultural sector of the Perm region. Agriculture in the region is more focused on the development of the livestock industry. Creation of self-regulatory organizations of the Perm region, which will include agricultural organizations, peasant farms, individual entrepreneurs, will allow to solve not only the production and financial and economic activities of members of SROs, but also to form human resources and manage the human resources of economic entities.
Consumer/survivor-run businesses : community economic development and self-help for people with a history of mental illness
Creators: name: Kerr, David George
Publisher: name: University of British Columbia
Year: 2009

description: Consumer/survivor-run businesses (CSRB's) are businesses in which people with a history of mental illness play a role in developing and managing the business. Key aspects of this type of activity include flexibility in working hours, and some form of democratic control over the business. Consumer/survivor-run businesses employ aspects of both community economic development and self-help for people with a history of mental illness. These businesses act as an alternative form of vocational rehabilitation for people with a history of mental illness. The predominant forms of vocational rehabilitation, such as sheltered work, employment preparation programs, transitional employment, and supported employment are often beneficial, but are not without limitations. Dependency on professionalized services, stagnation in entry-level jobs, and a lack of independence are some of the limitations described in the literature. Five cases of CSRB's from across Canada are analyzed. From the literature reviewed and the experiences of these cases, constraints faced by CSRB's and opportunities presented for support to them through public policy are discussed. The constraints included (i) bureaucratic restrictions that limit what consumer/survivors may earn on top of their disability pensions; (ii) attitudes of the general public, namely the stigma of mental illness; (iii) attitudes of mental health professionals, who hold to a 'service paradigm'; (iv) problems inherent in the development of alternative settings, and (v) the drift towards professionalism often experienced by alternative settings.
Magnetic flux emergence in granular convection: Radiative MHD simulations and observational signatures

description: We study the emergence of magnetic flux from the near-surface layers of the solar convection zone into the photosphere. To model magnetic flux emergence, we carried out a set of numerical radiative magnetohydrodynamics simulations. Our simulations take into account the effects of compressibility, energy exchange via radiative transfer, and partial ionization in the equation of state. All these physical ingredients are essential for a proper treatment of the problem. Furthermore, the inclusion of radiative transfer allows us to directly compare the simulation results with actual observations of emerging flux. We find that the interaction between the magnetic flux tube and the external flow field has an important influence on the emergent morphology of the magnetic field. Depending on the initial properties of the flux tube (e.g. field strength, twist, entropy etc.), the emergence process can also modify the local granulation pattern. The emergence of magnetic flux tubes with a flux of $10^{19}$ Mx disturbs the granulation and leads to the transient appearance of a dark lane, which is coincident with upflowing material. These results are consistent with observed properties of emerging magnetic flux.

description: We prove that four different ways of defining Cartesian fibrations and the Cartesian model structure are all Quillen equivalent: On marked simplicial sets, on bisimplicial spaces, on bisimplicial sets, on marked simplicial spaces. The main way to prove these equivalences is by using the Quillen equivalences between quasi-categories and complete Segal spaces as defined by Joyal-Tierney and the straightening construction due to Lurie.

description: We consider the problem of calculating the Green's functions associated to a massive scalar field with modified dispersion relations. We analyze the case when dispersion is modified by higher derivative spatial operators acting on the field orthogonally to a preferred direction, determined by a unit time-like vector field. By assuming that the integral curves of the vector field are geodesics, we expand the modified Klein-Gordon equation in Fermi normal coordinates. By means of a Fourier transform, we find a series representation in momentum-space of the Green's functions. The coefficients of the series are geometrical terms containing combinations of the Ricci tensor and the vector field, as expected from previous calculations with different methods and for specific backgrounds.

description: Supervised learning for semantic segmentation requires a large number of labeled samples, which is difficult to obtain in the field of remote sensing. Self-supervised learning (SSL), can be used to solve such problems by pre-training a general model with a large number of unlabeled images and then fine-tuning it on a downstream task with very few labeled samples. Contrastive learning is a typical method of SSL that can learn general invariant features. However, most existing contrastive learning methods are designed for classification tasks to obtain an image-level representation, which may be suboptimal for semantic segmentation tasks requiring pixel-level discrimination. Therefore, we propose a global style and local matching contrastive learning network (GLCNet) for remote sensing image semantic segmentation. Specifically, 1) the global style contrastive learning module is used to better learn an image-level representation, as we consider that style features can better represent the overall image features. 2) The local features matching contrastive learning module is designed to learn representations of local regions, which is beneficial for semantic segmentation. The experimental results show that our method mostly outperforms SOTA self-supervised methods and the ImageNet pre-training method. Specifically, with 1\% annotation from the original dataset, our approach improves Kappa by 6\% on the ISPRS Potsdam dataset relative to the existing baseline. Moreover, our method outperforms supervised learning methods when there are some differences between the datasets of upstream tasks and downstream tasks. Since SSL could directly learn the essential characteristics of data from unlabeled data, which is easy to obtain in the remote sensing field, this may be of great significance for tasks such as global mapping.
