Abstract:
Among design engineers, it is known that breaking symmetries of a brake rotor can help to prevent squeal. From a modelling point of view, in the literature brake squeal is almost exclusively treated using models with a symmetric brake rotor, which are capable of explaining the excitation mechanism but yield no insight into the relation between rotor asymmetry and stability. In previous work, it has been demonstrated with linear models that the breaking of symmetries of the brake rotor has a stabilizing effect. The equations of motion for this case have periodic coefficients with respect to time and are therefore more difficult to analyse than in the symmetric case. The goal of this article is to investigate whether due to the breaking of symmetries also, the non-linear behaviour of the brake changes qualitatively compared to the symmetric case.

Abstract:
Group theoretical methods are used to obtain the form of the elastic moduli matrices and the number of independent parameters for various symmetries. Particular attention is given to symmetry groups for which 3D and 2D isotropy is found for the stress-strain tensor relation. The number of independent parameters is given by the number of times the fully symmetric representation is contained in the direct product of the irreducible representations for two symmetrical second rank tensors. The basis functions for the lower symmetry groups are found from the compatibility relations and are explicitly related to the elastic moduli. These types of symmetry arguments should be generally useful in treating the elastic properties of solids and composites.

Abstract:
In this paper, we introduce types of relations on complex fuzzy sets such as the complex fuzzy (CF) inverse relation, complex fuzzy reflexive relation, complex fuzzy symmetric relation, complex fuzzy antisymmetric relation, complex fuzzy transitive relation, complex fuzzy irreflexive relation, complex fuzzy asymmetric relation, complex fuzzy equivalence relation, and complex fuzzy-order relation. We study some basic results and particular examples of these relations. Moreover, we discuss the applications of complex fuzzy relations in Future Commission Market (FCM). We show that the introduction of CF relations to applications of FCMs can give a significant method for describing the temporal dependence between parameters of a Future Commission Market.

Abstract:
We introduce the concepts of a bipolar fuzzy reflexive, symmetric, and transitive relation. We study bipolar fuzzy analogues of many results concerning relationships between ordinary reflexive, symmetric, and transitive relations. Next, we define the concepts of a bipolar fuzzy equivalence class and a bipolar fuzzy partition, and we prove that the set of all bipolar fuzzy equivalence classes is a bipolar fuzzy partition and that the bipolar fuzzy equivalence relation is induced by a bipolar fuzzy partition. Finally, we define an ( a , b ) -level set of a bipolar fuzzy relation and investigate some relationships between bipolar fuzzy relations and their ( a , b ) -level sets.

Abstract:
The concept of symmetry is omnipresent, although originally, in Greek antiquity, distinctly different from the modern logical notion. In logic a binary relation R is called symmetric if xRy implies yRx. In Greek, ‘being symmetric’ in general usage is synonymous with ‘being harmonious’, and in technical usage, as in Euclid's Elements, it is synonymous with ‘commensurable’. Due to the second meaning, which is close to the etymology of συ´μμετρoς, ‘with measure’ has likewise to be read as ‘being [in] rational [ratios]’ and displays the origin of the concept of rationality of establishing a proportion. Heraclitus can be read as a master of such connections. Exercising rationality is a case of simultaneously finding and inventing symmetries. On that basis a proposal is made of how to relate the modern logical notion of symmetry, a second-order concept, on the one hand with modern first-order usages of the term symmetric in geometry and other fields, and on the other hand with the notion of balance that derives from the ancient usage of symmetric. It is argued that symmetries as states of balance exist only in theory, in practice they function as norms vis-à-vis broken symmetries.

In this paper we present a way of perturbing reflexive, symmetric, antisymmetric, perfect antisymmetric, transitive and partially included intuitionistic fuzzy relations afterward obtaining the perturbation of another reflexive, symmetric, antisymmetric, perfect antisymmetric, transitive and partially included intuitionistic fuzzy relation. To do so we study the main properties of an operator that allows us to go from an intuitionistic fuzzy set to another also intuitionistic fuzzy set, we then apply this operator to intuitionistic fuzzy relations with different properties and we study the conditions there must be for the new intuitionistic fuzzy relation to maintain the original properties.

Full text
Abstract:
According to Wlodek Rabinowicz's fitting-attitude analysis of comparative value, it is possible to analyse both standard and non-standard value relations in terms of the standard preference relations and two levels of normativity. In a recent article, however, Johan Gustafsson has argued that Rabinowicz's analysis violates a principle of value–preference symmetry, according to which for any value relation, there is a corresponding preference relation. Gustafsson has proposed an alternative analysis which respects this principle and which allegedly accounts for the idea that originally motivated Rabinowicz's analysis, namely, that in some cases different preference relations between a pair of items are equally permissible. The goal of my article is to show that the arguments offered by Gustafsson in favour of his account do not succeed. In particular, I argue that Gustafsson faces a dilemma: either he abandons the principle of value–preference symmetry or he cannot make conceptual room for multiple permissible preferences.

Abstract:
Magnetic moments of the octet baryons are computed using lattice QCD in background magnetic fields, including the first treatment of the magnetically coupled ∑0- ⋀ system. Although the computations are performed for relatively large values of the up and down quark masses, we gain new insight into the symmetries and relations between magnetic moments by working at a three-flavor mass-symmetric point. While the spinflavor symmetry in the large Nc limit of QCD is shared by the naïve constituent quark model, we find instances where quark model predictions are considerably favored over those emerging in the large Nc limit. We suggest further calculations that would shed light on the curious patterns of baryon magnetic moments.

Full text
Abstract:
Relations between common information measures include the duality relations based on Möbius inversion on lattices, which are the direct consequence of the symmetries of the lattices of the sets of variables (subsets ordered by inclusion). In this paper we use the lattice and functional symmetries to provide a unifying formalism that reveals some new relations and systematizes the symmetries of the information functions. To our knowledge, this is the first systematic examination of the full range of relationships of this class of functions. We define operators on functions on these lattices based on the Möbius inversions that map functions into one another, which we call Möbius operators, and show that they form a simple group isomorphic to the symmetric group S3. Relations among the set of functions on the lattice are transparently expressed in terms of the operator algebra, and, when applied to the information measures, can be used to derive a wide range of relationships among diverse information measures. The Möbius operator algebra is then naturally generalized which yields an even wider range of new relationships.

Abstract:
In our independent work, the purpose for us is to gain an increased insight into the complex collaboration that exists between educators and guardians and to gain an increased insight into the relationship between educator and student. We believe that this is not a sufficiently explored topic in the after-school center and the challenge therefore lies in finding suitable literature that relates to our independent work. In this independent work, we start from our professional experiences in two difficult-to-assess dilemmas in school and leisure activities. Christopher's dilemma text is about his empathy for "his" student, and that Christopher chooses to tell a white lie to his student's mother to protect the student in question. Fredrik's dilemma text is similar to Christopher's, but the action differs from Christopher's text. Fredrik chooses to tell the truth to “his” student's mother in the belief of being able to see things in a larger perspective and thus create better conditions for the student's schooling. In our independent work, we have used methods such as: scientific essay writing and hermeneutic approach. The theories we have chosen to use are the relationship between educator and student, the relationship between school and home and ethical perspectives. We have then linked the theory part to our individual and joint reflections. Our study deals with the asymmetric versus the symmetrical relationships that exist between adults and children and the interpretive preference that adults have. We discuss the UN Convention on the Rights of the Child and how complex it is to decide what is in the best interests of the child and who can decide it. In the theory part that deals with the relationship between school and home, we highlight the problematic collaboration that exists between educators and guardians. We also highlight the collaboration with an intercultural perspective where cultures and traditions have a great impact. In the study, we write about how we can work to achieve a better collaboration with the homes. We also shed light on the concept of practical knowledge and how it can be expressed in our professional profession. Finally, in the theory part, we deal with ethics of duty, ethics of discourse, ethics of utility and ethics of proximity. At the end of our independent work, we write about our lessons from the study and concluding thoughts about what we learned during the work. Keywords: collaboration, communication, ethics, asymmetric / symmetrical relationship, leisure center, school, trust, dialogue, relationship competence, practical knowledge.
I vårt självständiga arbete är syftet för oss att få en ökad insikt i den komplexa samverkan somfinns mellan pedagoger och vårdnadshavare samt att få en ökad insikt i relationen mellan pedagog och elev. Vi anser att detta inte är ett tillräckligt utforskat ämne inom fritidshemmet och utmaningen ligger därför i att hitta lämplig litteratur som rör vårt självständiga arbete. I detta självständiga arbete utgår vi från våra yrkeserfarenheter i två svårbedömda dilemman inom skol- och fritidsverksamheten. Christophers dilemmatext handlar om hans empati för ”sin” elev, och att Christopher väljer att dra en vit lögn för sin elevs mamma för att skydda eleven ifråga. Fredriks dilemmatext är snarlik Christophers men handlandet skiljer sig från Christophers text. Fredrik väljer att berätta sanningen för ”sin” elevs mamma i tron om att kunna se saker i ett större perspektiv och således skapa bättre förutsättningar för elevens skolgång. I vårt självständiga arbete har vi använt oss av metoder som: vetenskapligt essäskrivande och hermeneutiskt förhållningssätt. De teorier som vi valt att använda oss av är relationen mellan pedagog och elev, relationen skola och hem samt etiska perspektiv. Teoridelen har vi sedan kopplat till våra individuella och gemensamma reflektioner. Vår studie behandlar de asymmetriska kontra de symmetriska relationerna som finns mellan vuxna och barn samt det tolkningsföreträde som vuxna har. Vi diskuterar kring FN:s barnkonvention och hur komplext det är att avgöra vad som är barnets bästa och vem som kan besluta det. I teoridelen som behandlar relationen skola och hem belyser vi det problematiska samarbetet som finns mellan pedagoger och vårdnadshavare. Vi belyser även samarbetet med ett interkulturellt perspektiv där kulturer och traditioner har en stor påverkan. I studien skriver vi om hur vi kan arbeta för att nå ett bättre samarbete med hemmen. Vi belyser även begreppet praktisk kunskap och hur det kan ta sig i uttryck i vår yrkesprofession. Avslutningsvis i teoridelen behandlar vi pliktetik, diskursetik, nyttoetik och närhetsetik. I slutet av vårt självständiga arbete skriver vi om våra lärdomar från studien samt avslutande tankar kring vad vi lärt oss under arbetets gång.

Abstract:
Abstract A progenitor developed by Robert T. Curtis is a type of infinite groups formed by the semi-direct product of a free group m∗n and a transitive permutation group of degree n. To produce finite homomorphic images we had to add relations to the progenitor of the form 2∗n : N. In this thesis we have investigated several permutations progenitors and monomials, 2∗12 : S4, 2∗12 : S4 × 2, 2∗13 : (13 : 4), 2∗30 : ((2• : 3) : 5), 2∗13 :13,2∗13 :(13:2),2∗13 :(13:S3),53∗2 :m (13:4),7∗8 :m (32 :8),and 53∗4 :m (13 : 4). We have discovered that the permutations progenitors produced the following finite homomorphic images, we have found P GL(2, 13), U3 (4) : 2, 2 × Sz (8), PSL(2,7), PGL(2,27), PSL(2,8), PSL(3,3), 4•S4(5), PSL2(53), and 13 : PGL2(53) as homomorphic images of this progenitors. We will construct double coset enumeration for the homomorphic images, 2 × Sz (8) over (13 : 4) Suzuki twisted group, P GL(2, 13) over S4,and PSL(2,7) over S4 and Maximal subgroups of 2×PGL(2,27) over 2•(13 : 2), P SL(2, 8) over (9 : 2), and P SL(3, 3) over (13 : 3). We will also give our techniques of finding finite homomorphic images and their isomorphism images.

Abstract:
This study intends to research SVT’s work with dialogical and symmetrical two-way communication with their audience on the social media site Facebook. Because of SVT’s position as the government’s public broadcasting service, they inheret a certain responsibility towards the population of Sweden. With this study we aim to observe and analyze SVT’s communication on Facebook based on theories, interviews and their own policy regarding communication online. To be able to reach our goals with this study we are going to analyze the policy document as well as articles regarding social media use from SVT, interview communicators at SVT and also perform an analysis on one of SVT’s Facebook pages based on online observations. When analysing the content of the Facebook page we are using a synthesized definition of the theoretical frameworks and models regarding dialogue, two-way communication and deliberative democracy. Our results show that SVT’s own definition of dialogue differs from an academic definition of the very specific and complicated concept of dialogue. In our research we notice that SVT aims to market themselves and perform dialogue simultaneously, which becomes problematic due to the strict academic definitions of the dialogue-notion. The interaction between SVT and their stakeholders on Facebook mostly contain simple questions regarding the organisation’s broadcasting and range which does not provide the right conditions for dialogue.

Abstract:
Governments often fund foreign nationals to live, work and study in their countries, creating specialist programmes tasked with promoting international mobility. In this thesis I establish that much of this funding is intended to serve a public diplomacy agenda, improving international relations to the benefit of the sponsor. Expectations about how offering funding to foreigners affects international relations have come to centre on what I label the ‘symmetric public diplomacy model’, which suggests that governments intend to influence other countries’ behaviour by influencing their citizens. I tested this model using a combination of panel surveys and interviews with students who took part in these programmes. Although mobility programmes do bring many educational and personal benefits to participants, my results do not support the expectation that they endow most visiting foreigners with more helpful attitudes than they would have developed had they not taken part in the programmes. While other studies have come to different conclusions on this issue, the research design employed in this thesis is better-suited to the task than most others. Mobility programmes may bring diplomatic benefits by other means. One possibility is that the act of creating, for example, scholarships for foreign nationals sends signals to foreign governments. The histories of major British scholarship programmes suggest that they were originally created to signal goodwill or distract attention from potentially-embarrassing policies. Despite this, administrators now present these programmes as tools of public diplomacy. The symmetric public diplomacy model has been applied to these programmes long after they were initially created, and I suggest that the model may have been adopted because it is useful for attracting funding to continue and expand mobility programmes.

Abstract:
This thesis is concerned with the utilization of object symmety as a cue for segmentation and object recognition. In particular it investigates the problem of detecting 3D bilaterally symmetric objects from affine views. The first part of the thesis investigates the problem of detecting 3D bilateral symmetry within a scene from known point correspondences across two or more affine views. We begin by extending the notion of skewed symmetry to three dimensions, and give a definition in terms of degenerate structure that applies equally to an affine 3D structure or to point correspondences across two or more affine views. We then consider the effects of measurement errors on symmetry detection, and derive an optimal statistical test of degenerate structure, and thereby of 3D-skewed symmetry. We then move on to the problem of searching for 3D skewed symmetric sets within a larger scene. We discuss two approaches to the problem, both of which we have implemented, and we demonstrate fully automatic detection of 3D skewed symmetry on images of uncluttered scenes. We conclude the first part by investing means of verifying the presence of bilateral rather than skewed symmetry in the Euclidean space, by enforcing mutual consistency between multiple skewed symmetric sets, and by drawing on partial knowledge about the camera calibration. The second part of the thesis is concerned with the problem of obtaining feature correspondences across multiple affine views, as required for the detection of symmetry. In particular we investigate the geometric matching constraints that exist between affine views. We start by specilizing the four projective multifocal tensors to the affine case, and use these to carry the bulk of all known projective multi-view matching relations to affine views, unearthing some new relations in the process. Having done that, we address the problem of estimating the affine tensors. We provide a minimal set of constraints on the affine trifocal tensor, and search for ways of estimating the affine tensors from point and line correspondences.

Abstract:
Web 2.0 har möjliggjort och öppnat upp för en ny typ av mellanmänsklig kommunikation. Numera kan vem som helst starta sin egen offentliga och lättillgängliga webbplattform där digitala dialoger frodas och med det skapas attraktiva marknadsplatser för företag. Enligt forskningsluckan vi har identifierat anser vi att det saknas insikter om hur företag på bästa sätt ska arbeta med bloggare utifrån bloggarnas perspektiv. Bloggar är inte bara en attraktiv marknadsplats för företag utan också för bloggarna själva som skapar sitt personliga varumärke genom att bygga upp den digitala identitet som presenteras i bloggen. Således är syftet med vår uppsats att bidra till ökad förståelse för bloggares preferenser i relationen med företag och varumärken, samt hur de väljer varumärken att beröra i sin blogg utifrån sin digitalt konstruerade identitet. För att genomföra vår studie har vi valt en kvalitativ metod med en abduktiv ansats där vi har genomfört semistrukturerade intervjuer med sju populära bloggare i Sverige. Den teoretiska referensramen som ligger till grund för vår studie är uppdelad i tre huvudkategorier; marketing public relations, word-of-mouth/word-of-blog samt personligt varumärke, där vi berör begreppen relationer, digitala dialoger, tvåvägs-symmetrisk kommunikation, digitalidentitet och källtrovärdighet. Resultatet i vår studie visar att bloggare önskar ett professionellt bemötande i relationen med PR-utövare men en personlig relation till varumärken. PR-utövare bör erbjuda bloggarna unikhet, involvering, nyhetsvärde och arvode för att skapa fördelaktiga tvåvägs-symmetriska bloggrelationer i syfte att gynna varumärket. Således förändras synen på traditionell PR vilket snarare innefattar relationer än finansiering. I vår studie presenterar vi därför en definition och modell av begreppet Blog Public Relations (BPR) vilket är vårt huvudsakliga bidrag till den vetenskapliga diskursen. Vidare visar vår undersökning att det finns tre faktorer som påverkar bloggare till att avvika från sin digitala identitet i samarbetet med företag. Förutom att de känner en press att uppdatera bloggen, och därmed ibland har valt att skriva om vissa produkter på grund av det, påverkar ett högt arvode eller ett riktigt bra och proffsigt bemötande från PR-utövarna den kommersiella avvägningen.
Web 2.0 has enabled and opened up for a new type of interpersonal communication. Nowadays, anyone can start their own public and accessible web platform where digital dialogues flourish and thus the creation of attractive markets for companies. According to the research gap we have identified, we believe that there is a lack of understanding of how companies’ best should practice blog relationships according to the bloggers. Blogs are notonly an attractive marketplace for companies but also for the bloggers themselves since they create their own personal brand by building up their digital identities that are presented in the blog. Thus, the purpose of this essay is to contribute to a better understanding of bloggers' preferences in their relationship with companies and brands and how they choose brands to mention in the blog from their digitally constructed identities. To carry out our study, we chose a qualitative method with an abductive nature where we have carried out semistructured interviews with seven popular bloggers in Sweden. The theoretical framework that forms the basis of our study is divided into three main categories; marketing public relations, word-of-mouth/word-of-blog, and personal brand, where we touch the concepts of relationships, digital dialogues, two-way symmetrical communication, digital identity and source credibility. The result of our study shows that bloggers wish for a professional approach in the relationships with PR practitioners and a personal relationship with the brands. PR practitioners should offer bloggers uniqueness, involvement, news-value and emolument to create beneficial two-way symmetric blog relationships in order to promote the brand. Moreover, this approach is changing the perception of traditional PR, which includes relationships, rather than financing. In our study, we therefore present a definition and model of the term Blog Public Relations (BPR) that is our main contribution to the scientific discourse. Furthermore, our study shows that there are three factors that influence bloggers to deviate from their digital identity in collaboration with companies. Besides that they feel pressured to update the blog, and thus sometimes chose to write about certain products because of it, a high emolument or a really good and professional behavior from PR practitioners affects the commercial balance.

Then we examine embedding stable and consistent statistics on the affine Weyl group of type A which permit the definition of an affine infinite symmetric group.

Abstract:
Surveys show that consumers tend to avoid traditional marketing channels, leading the practitioners to use earned media channels through public relations (PR). This has also led to the use of covert PR. To understand the use of this communications method, the purpose of this thesis is to study campaigns, which have gained transmission in social media, by investigating how practitioners of three different campaigns motivate the choice to use covert PR. The study is based on a hermeneutic methodology and has an abductive approach. It is carried out by semi-structured elite interviews with six contributors of three different campaigns, using covert PR. The primary data consists of the empery of the interviews, while the secondary data consists of a theoretical framework of excellence in public relations, the PR practice and viral messages. The result of the study indicates the point of view that covert PR has given the campaigns a wider reach. Furthermore the campaigns are described as having gained an extensive viral transmission, which exceeded the expectations of the interviewees. Nevertheless none of the practitioners think they will do a similar campaign again, it seems that they are aware of the risk of covert PR reducing the organisation’s reputation. The analysis also show a contradiction between the interviewees’ position and the presented theory, which might be caused by a perspective on PR as a way of spreading information rather than creating relationships.
Undersökningar visar att konsumenter i allt större utsträckning undviker reklam, vilket har gjort att kommunikationspraktiker i större utsträckning väljer förtjänade kanaler, eller public relations (PR), för att nå sina målgrupper. En följd av det är PR-aktiviteter med dolda avsändare. Med utgångspunkt i den debatt som finns kring metoden är syftet med studien att undersöka PR som fått viral spridning med avseende på hur tre kampanjer utformats och hur praktikerna bakom dessa i efterhand motiverar och resonerar kring valet av dold viral PR. För att få förståelse för fenomenet och varför sådana kampanjer genomförs har studien ett hermeneutiskt förhållningssätt och en abduktiv ansats. Undersökningen har genomförts med en kvalitativ metod genom semistrukturerade elitintervjuer med sex stycken praktiker som jobbat med någon av tre valda kampanjer. Det empiriska materialet i form av intervjuerna utgör studiens primärdata, medan dess sekundärdata består av teorier och tidigare forskning om excellens i public relations, PR i praktiken och viral spridning i sociala medier. Resultatet visar att den dolda avsändaren och dess avslöjande anses bidra till viral spridning. Kampanjerna motiveras med att de nått stora målgrupper, väckt debatt och varit underhållande – och räckvidden har överträffat praktikernas förväntningar. Ändå nämner alla att det inte är önskvärt att förknippas med metoden. Respondenternas utsagor går till viss del emot teorins normativa resonemang, vilket möjligtvis skulle kunna förklaras av en syn på PR som informationsspridande snarare än relationsskapande.

Abstract:
Metaphysical orthodoxy maintains that the relation of ontological dependence is irreflexive, asymmetric, and transitive. The goal of this paper is to challenge that orthodoxy by arguing that ontological dependence should be understood as non-symmetric, rather than asymmetric. A series of cases across a wide range of ontological commitments are presented, and it is argued that each case should be understood as one in which the relation of dependence holds symmetrically. If these arguments work, however, they provide reasons to be skeptical of the way in which contemporary discussions typically lump dependence together with relations such as grounding and in virtue of, which arguably need to be understood as asymmetric. If the asymmetry of dependence is relinquished, interesting things follow for what can be said about metaphysical explanation—particularly for the prospects of explanatory holism.

Abstract:
The fact that physical laws often admit certain kinds of space-time symmetries is often thought to be problematic for substantivalism—the view that space-time is as real as the objects it contains. The most prominent alternative, relationism, avoids these problems but at the cost of giving abstract objects (rather than space-time points) a pivotal role in the fundamental metaphysics. This incurs related problems concerning the relation of the physical to the mathematical. This paper presents a version of substantivalism that respects Leibnizian theses about space-time symmetries, and argues that it is superior to both relationism and the more orthodox form of substantivalism.

Abstract:
This paper argues for an alternative to orthodox foundationalist accounts of metaphysical structure as characterized by grounding relations. There are good reasons to take grounding to be a non-symmetric (rather than an asymmetric) relation, and to take facts to be related in complex networks of ground. These networks are closely analogous to the networks of justified beliefs characteristic of coherentism about justification. This position is called metaphysical interdependence. The chapter argues that grounding is an explanatory relation (rather than merely a relation which backs explanations), and that there are good reasons to resist the contention that explanation is asymmetric, including cases seemingly best described as cases of holistic metaphysical explanation. Metaphysical interdependence is a promising account of the metaphysical structure of reality.

Abstract:
This chapter introduces the divergence equation. A key ingredient in the proof of the Main Lemma for continuous solutions is to find special solutions to this divergence equation, which includes a smooth function and a smooth vector field on ³, plus an unknown, symmetric (2, 0) tensor. The chapter presents a proposition that takes into account a condition relating to the conservation of momentum as well as a condition that reflects Newton's law, which states that every action must have an equal and opposite reaction. This axiom, in turn, implies the conservation of momentum in classical mechanics. In view of Noether's theorem, the constant vector fields which act as Galilean symmetries of the Euler equation are responsible for the conservation of momentum. The chapter shows proof that all solutions to the Euler-Reynolds equations conserve momentum.

Abstract:
Chapter 5 determines the semantic typology of patterns III and VI, sometimes termed the vowel-lengthening patterns. It asserts that verbs formed in these patterns are symmetrical predicates, denoting relations consisting of two complementary forces. It shows that the difference between the two patterns results from the interplay between an underlying symmetric relation and a figure–ground orientation in which one of the participant roles involved is made more prominent than the other. The chapter divides verbs formed in pattern III into verbs of resistance, risk, competition, interaction, and co-action, and those formed in pattern VI into reciprocal verbs, feigning verbs, chaining verbs, and verbs of progressive change. It argues that an account based on a common symmetric structure is able to unite this diverse range of verbs within one analysis, and it offers data from other languages to support this claim.

Abstract:
Abstract We consider the decidability of the verification problem of programs modulo axioms — automatically verifying whether programs satisfy their assertions, when the function and relation symbols are interpreted as arbitrary functions and relations that satisfy a set of first-order axioms. Though verification of uninterpreted programs (with no axioms) is already undecidable, a recent work introduced a subclass of coherent uninterpreted programs, and showed that they admit decidable verification [26]. We undertake a systematic study of various natural axioms for relations and functions, and study the decidability of the coherent verification problem. Axioms include relations being reflexive, symmetric, transitive, or total order relations, functions restricted to being associative, idempotent or commutative, and combinations of such axioms as well. Our comprehensive results unearth a rich landscape that shows that though several axiom classes admit decidability for coherent programs, coherence is not a panacea as several others continue to be undecidable.

Abstract:
Multi-task clustering improves the clustering performance of each task by transferring knowledge among the related tasks. An important aspect of multi-task clustering is to assess the task relatedness. However, to our knowledge, only two previous works have assessed the task relatedness, but they both have limitations. In this paper, we propose a multi-task clustering with model relation learning (MTCMRL) method, which automatically learns the model parameter relatedness between each pair of tasks. The objective function of MTCMRL consists of two parts: (1) within-task clustering: clustering each task by introducing linear regression model into symmetric nonnegative matrix factorization; (2) cross-task relatedness learning: updating the parameter of the linear regression model in each task by learning the model parameter relatedness between the clusters in each pair of tasks. We present an effective alternating algorithm to solve the non-convex optimization problem. Experimental results show the superiority of the proposed method over traditional single-task clustering methods and existing multi-task clustering methods.
