Opis:
For two-dimensional manifold M with locally symmetric connection ∇ and with ∇-parallel volume element vol one can construct a flat connection on the vector bundle TM ⊕ E, where E is a trivial bundle. The metrizable case, when M is a Riemannian manifold of constant curvature, together with its higher dimension generalizations, was studied by A.V. Shchepetilov [J. Phys. A: 36 (2003), 3893-3898]. This paper deals with the case of non-metrizable locally symmetric connection. Two flat connections on TM ⊕ (ℝ × M) and two on TM ⊕ (ℝ2 × M) are constructed. It is shown that two of those connections – one from each pair – may be identified with the standard flat connection in ℝN, after suitable local affine embedding of (M,∇) into ℝN.

Opis:
The paper deals with the analysis of syntactic connection between unattached phrases (with characterizing semantics, but without detailing semantics) and the structure of the basic sentence. The author proves that various structural-semantic types of unattached phrases have diff erent grammatical ways of connection with the basic sentence. The semipredicative syntactic connection occurs between an unattached component of properlyattribute semantics and any substantive of the basic sentence. Unattached adverbial modifiers and also unattached attributes of attribute-adverbial semantics and unattached appositions of characterizing-adverbial semantics join the predicative centre of the basic sentence with the determinative subordinate syntactic connection. And the syntactic connection in sentences with an unattached adjective component of dual-predicate (predicative attribute, duplexes) is a transitional between unitary and dual types.

Opis:
Rainbow connection number of Cartesian products and their subgraphs are considered. Previously known bounds are compared and non-existence of such bounds for subgraphs of products are discussed. It is shown that the rainbow connection number of an isometric subgraph of a hypercube is bounded above by the rainbow connection number of the hypercube. Isometric subgraphs of hypercubes with the rainbow connection number as small as possible compared to the rainbow connection of the hypercube are constructed. The concept of c-strong rainbow connected coloring is introduced. In particular, it is proved that the so-called Θ-coloring of an isometric subgraph of a hypercube is its unique optimal c-strong rainbow connected coloring.

An edge-coloured graph G is rainbow connected if any two vertices are connected by a path whose edges have distinct colours. The rainbow connection number of a connected graph G, denoted rc(G), is the smallest number of colours that are needed in order to make G rainbow connected. In this paper we prove that rc(G) = 2 for every connected graph G of order n and size m, where $\binom{n-1}{2} + 1 ≤ m ≤ \binom{n}{2} - 1$. We also characterize graphs with rainbow connection number two and large clique number.

In [C] and [F1] the connection matrix theory for Morse decomposition is developed in the case of continuous dynamical systems. Our purpose is to study the case of discrete time dynamical systems. The connection matrices are matrices between the homology indices of the sets in the Morse decomposition. They provide information about the structure of the Morse decomposition; in particular, they give an algebraic condition for the existence of connecting orbit set between different Morse sets.

Opis:
A fatigue assessment of steel structures based on the safe life approach requires a detail category representing the fatigue strength. For flexible culverts there are no matching details in the governing regulations. In this paper the testing and evaluation of the fatigue strength of a standardized bolted connection for steel culverts are presented. A test rig was designed to mimic the in-service conditions with a combination of bending moment and axial force. A total of ten specimens was tested to failure. The failure was governed cracks initiating at the indentations from the bolt heads and propagated towards the nearest edge. From the test results, an S-N curve has been derived suggesting a characteristic fatigue strength of 124 MPa at 2 million cycles and a slope of 5 in log-log scale.

Opis:
In the most general terms, the Logical Connection Argument (LCA) states that theory and practice are two inseparable aspects of the same thing. Every action (or practice), linguistic or otherwise, is an indivisible unity of content and the means by which it is expressed. Alternatively, we may talk of the inseparability of content and form, meaning and act of expression, goal and method or means of its realization, and so forth. The argument was meant to prove that intentions cannot be treated as causes in social scientific explanation, but it did it at the cost of making any meta-analysis, and hence, critique, highly problematic. My position is that the LCA is indeed logical, and hence irrefutable. Nonetheless, we can distinguish between “raw” and “refined” versions of the argument. The refined version maintains that while ultimately and ideally, the content and means of expression presuppose one another in the sense that a content is inconceivable without a form, and vice versa, in reality there is never a perfect match between aims and methods. In typical circumstances, we do not have a precise sense of what we are doing; the meaning of our actions is gradually discovered in the course of exploratory behaviors, of which (immanent) critique is an indispensable part. In this contribution, I venture to examine the problem from a neuropsychological perspective with the view to showing in exactly what sense and to what extent explorative behaviors and associated motivations preside over other activities. I argue that content is always underdetermined with respect to its form (and vice versa), and hence the alleged internal connection between them is not a given, but rather amounts to a regulative principle which motivates mutual adjustments.

Opis:
Our discussion in this article centers around various issues related to the use of anycasting in connection-oriented computer networks. Anycast is defined as a one-to-one-of-many transmission to deliver a packet to one of many hosts. Anycasting can be applied if the same content is replicated over many locations in the network. Examples of network techniques that apply anycasting are Content Delivery Networks (CDNs), Domain Name Service (DNS), Peer-to-Peer (P2P) systems. The role of anycasting is growing concurrently with the popularity of electronic music, movies, and other content required by Internet users. In this work we focus on the optimization of anycast flows in connection-oriented networks. We formulate a model of anycast connections and next propose a heuristic algorithm based on the Lagrangean relaxation aimed to optimize jointly routes for anycast and unicast connections. Results of numerical experiments are presented and evaluated. Finally, we analyze briefly problems related to anycasting in dynamic routing and multi-layer networks.

Opis:
The connection between law and (imaginative) literature can still affect surprisingly. The theme of the present article is to summarize some of the basic features of the movement, which is called „Law and Literature” and to suggest some starting-points with which it is associated. These starting points include, for instance linguistic conception of law, narratology in law or the relations between law and culture. The article offers an overview of the classical approaches connecting law and literature and mentions the reasons for this connection: e.g. cultivation of law and lawyers, improvement of judicial decisions or improvement of legal interpretation. Some of the findings resulting from the joint of law and literature can be used in practice and goes beyond „mere” theory. The article is to be seen as an introduction to the movement of „Law and Literature”, presentation of ideas on which this movement is based and offering the possibility of its further development.

We will then mention some of the physical and geographical characteristics of the study area: its geographical position, relief, climate and flora and their role on the development of the study area’s population. We will make an evaluation of the area’s infrastructure and its role on the communication and connection with the other areas. The methodology employed is that of a questionnaire. The questionnaire, the data analysis and the publication of results took us a period of one year. The results were analyzed by giving the social, political and economical reasons that break off the spiritual connection to the living place, the present situation and the tendency by giving conclusions and recommendations that we think will be of great help to the solution of such an important issue in this period of enormous changes in every aspect.

In the paper modelling and calculations of an asymmetrical multi-bolted connection at the operational stage are presented. The physical model of the joint is based on a flexible flange element that is connected with a rigid support by means of linear spring elements, which substitute bolts. Between the flange element and the support, the linear Winkler model of a contact layer is taken into consideration. The multi-bolted system is preloaded and then subjected to an eccentric normal load. Influence of nonlinearity of the contact layer between joined elements on computational values of bolt forces has been investigated. Results of calculations for several different values of the joined element’s thickness are pointed out.

Opis:
The aim of the paper is to analyse an exemplary bolted connection under the conditions of loss of bearing capacity of some fasteners in the connection. The presented tests are numerical and concern an asymmetric bolted connection. The joined elements in the connection were modelled as 3D finite elements, and the fasteners were treated as hybrid models consisting of rigid heads and nuts, and flexible beams between them. The bolted connection was first preloaded according to six different tensioning orders using a standardised force. After all bolts were tensioned, the selected bolts were removed, simulating bolt damage. The connection was then tested for external loads with temperatures ranging from 20 to 600°C. The influence of loosening the connection on the load in the remaining bolts at the operational stage of the connection was investigated. The calculation results were compared with the test results for a healthy bolted connection. It was shown that the bearing capacity of the connection in the damaged state decreased by 13%.

This article explores how the use of communication technology has transformed social interactions and the sense of self that is derived from such interactions by considering the role of presence and absence in relationships among college students. Analyzing interviews with 38 participants, I explore how they construct understandings of presence, absence, connection, and disconnection within peer social groups and intimate relationships, indicating the emergence of a culture of hyper-connection. I suggest that technological developments have enabled forms of interaction that encourage frequent connection and the idealization of constant communication among participants. These findings further indicate that the normalization of hyper-connection may have impacts on relationship practices and constructions of identity among participants.

The article presents an example of the use of functional series for the analysis of nonlinear systems for discrete time signals. The homogeneous operator is defined and it is decomposed into three component operators: the multiplying operator, the convolution operator and the alignment operator. An important case from a practical point of view is considered – a cascade connection of two polynomial systems. A new, binary algorithm for determining the sequence of complex kernels of cascade from two sequences of kernels of component systems is presented. Due to its simplicity, it can be used during iterative processes in the analysis of nonlinear systems (e.g. feedback systems).

Opis:
Everyday spaces represent central platforms that provide opportunities for encounters marked by ethnic and cultural diversity, where transformations can be negotiated that rethink living together. The significance of these ‘third places’ has been extensively researched. Yet, some spaces such as public libraries continue to be largely overlooked by geographers. Public libraries also remain under-appreciated within wider society despite their obvious social functions. Central here is that public libraries can be understood as dynamic and ‘lived spaces’ that enable the emergence of transient connections and relationships. Such spaces are increasingly sparse within modern cities. This paper explores the potential of everyday spaces of encounter, specifically public libraries, to facilitate the unfolding of ‘light’ connections and relationships, nurturing more inclusive forms of urban togetherness and belonging in multi-ethnic societies and the significance that people attribute to these often mundane encounters and micro connections. In so doing, this paper combines findings from two research projects that investigate mixed or intercultural encounters in public libraries in Bremen (Germany) and Glasgow (Scotland).

Opis:
Air conditioning systems in vehicles require long-term reliability during their entire service life. Especially, a good sealing function is needed for the prevention of coolant leaking. Unfortunately, in specific cases, after a particular time, screw connections of the air conditioning circuit lose their tightness, and the coolant starts to leak. Therefore, this paper focuses on the analysis and design optimisation of screw connections. We used the finite element method for describing the sealing, screw and disc spring behaviour. Then, we proposed a new design of the disc spring to obtain the proper force-deformation characteristics of the connection and ensure the tightness of the screw connection.

Opis:
Steel frame wind bracing systems are usually made of hot rolled profiles connected to frame elements directly or through a gusset plate. The behaviour of angle bracing members is generally complex since controlled by tension or compression, bending and torsion. The common practice is to transform the problem of complex behaviour into the buckling strength of a truss member. This paper deals with an analytical formulation of the force-deformation characteristic of a single angle brace subjected to compression. A strut model takes into consideration the effect of brace end connections and softening effect of its force-deformation characteristic. Two different boundary conditions, typical for engineering practice, are dealt with. Experimental program of testing the behaviour of angle brace in portal sub-frame specimens is described. Results of experimental investigations are presented. They are used for the validation of developed model. Conclusions are formulated with reference to the application of validated brace model in the analysis of braced steel frameworks.

Opis:
A path in an edge-coloured graph is called a rainbow path if its edges receive pairwise distinct colours. An edge-coloured graph is said to be rainbow connected if any two distinct vertices of the graph are connected by a rainbow path. The minimum k for which there exists such an edge-colouring is the rainbow connection number rc(G) of G. Recently, Bau et al. [Rainbow connectivity in some Cayley graphs, Australas. J. Combin. 71 (2018) 381–393] introduced this concept with the additional requirement that the edge-colouring must be proper. The proper rainbow connection number of G, denoted by prc(G), is the minimum number of colours needed in order to make it properly rainbow connected. Obviously, prc(G) ≥ max{rc(G), χ′(G)}. In this paper we first prove an improved upper bound prc(G) ≤ n for every connected graph G of order n ≥ 3. Next we show that the difference prc(G) – max{rc(G), χ′(G)} can be arbitrarily large. Finally, we present several sufficient conditions for graph classes satisfying prc(G) = χ′(G).

Opis:
The article is devoted to the study of modern problematic issues of causation in criminal law. These issues include, in particular, the issue of relevance of causation in criminal law itself, and the specifics of manifestations of relevance of causation in criminal law. The article notes that the purpose of scientific research is to identify and analyze the characteristics and criteria of relevant causation. The methods of the presented study include dialectical, systemic-structural, logical, etc. The results of the study are summarized in a number of important provisions. The author emphasizes the importance of the study of causation in criminal law as a formal and legal one, which is related to the study of causation as relevant, meeting the requirements and solving the problems of modern criminal law. The article notes that the characterization of causation in criminal law should not be limited to the connection between an act and socially dangerous consequences, since causality expressed by causation is manifested in a combination of components which are part of the content of various criminal law institutions. The article examines some characteristics of the relevance of causation in criminal law. Attention is drawn to the importance of legal and technical reflection of causation in criminal law as a condition for the relevance of causation. The article notes that the formalization of causation is the basis for considering such a connection as relevant (meeting legal requirements). The author examines institutional and inter-institutional manifestations of causation in criminal law. Furthermore, the author examines the causal manifestations which combine a criminal offense (in particular, a crime) and the legal consequences provided for by criminal law in relation to the subject who committed the offense. The article examines the peculiarities of causation in relation to certain criminal law institutions. The main conclusions of the study are the following: the need to clarify the criteria of relevant causation, the statement of relevant causation in criminal law within certain criminal law institutions, the need to consider causation in a broader criminal law context, and not only within the corpus delicti, etc.

Opis:
The main objective of this paper is to develop an effective evolutionary algorithm (EA) for the path-assignment problem in survivable connection-oriented networks. We assume a single-link failure scenario, which is the most common and frequently reported failure event. Since the network flow is modeled as a non-bifurcated multicommodity flow, the discussed optimization problem is NP-complete. Thus, we develop an effective heuristic algorithm based on an evolutionary algorithm. The main novelty of this work is that the proposed evolutionary algorithm consists of two levels. The “high” level applies typical EA operators. The “low” level is based on the idea of a hierarchical algorithm. However, the presented approach is not a classical hierarchical algorithm. Therefore, we call the algorithm quasi-hierarchical. We present its description and the results of simulation runs over various networks.

Opis:
In this study, the non-preloaded bolted connection of a roof girder, commonly used in steel halls with a frame system, was analyzed. Two options were considered: a connection before reinforcement and one reinforced by adding a new row of bolts. For both of the analyzed variants, analytical calculations were performed based on the component method and numerical calculations using the Finite Element Method. The load capacity of the connection was checked before and after reinforcement. A large convergence of the calculation results for both methods was demonstrated. It was confirmed that the proposed reinforcement of the existing joint of the roof girder (by adding an new row of bolts) easily increases its load capacity (for the analyzed case, the load capacity of the connection increased by approx. 28%). Such a reinforcement can be performed under load, with minimal interference to the existing joint, and the high deformability (elongation ability) of the bolts used allows for a full redistribution of internal forces in the reinforced joint.
Poddano analizie niesprężone połączenie śrubowe rygla dachowego, występujące powszechnie w halach stalowych o układzie ramy pełnościennej. Rozpatrzono dwa warianty: połączenie przed wzmocnieniem oraz po wykonaniu wzmocnienia poprzez dodatnie nowego szeregu śrub. Dla obu analizowanych wariantów wykonano obliczenia analityczne w oparciu o metodę składnikową oraz numeryczne wykorzystujące metodę elementów skończonych. Sprawdzono nośność połączenia przed i po wzmocnieniu. Wykazano dużą zbieżność wyników obliczeń dla obu zastosowanych metod. Potwierdzono, iż zaproponowane wzmocnienie istniejącego połączenia doczołowego rygla dachowego (poprzez dodanie dodatkowego szeregu śrub) po zwala w prosty sposób zwiększyć jego nośność (dla analizowanego przypadku nośność połączenia wzrosła o ok. 28%). Wzmocnienie takie można wykonać pod obciążeniem, przy minimalnej ingerencji w istniejący styk, a wysoka odkształcalność (zdolność do wydłużenia) zastosowanych śrub pozwala na pełną redystrybucje sił wewnętrznych we wzmocnionym połączeniu.

In this paper the distribution of pressure on surfaces of the screw's connections with preload tension is considered. A joining model which is used in rolling bearing is the subject of the analysis. The aim of the work is to introduce an auxiliary criterion of 'connection tightness' to the calculating methodology of bearings' fastening connections with building structure. Considered part of the three-row roller bearing, rings bearings and mounting elements are modelled solid type, and the bolts are modelled with beam-type element introduced preload tension value equivalent catalogue. Connected elements of the screw head rigid elements. The screws used in such a combined coronary bearings are not close fit, and established contact between the surfaces of the rings and the building is not homogeneous. Work is not only dedicated to the stress of contact between the contact surfaces A and B, but also considered is the effect of pitch spacing of the screws on the pitch rolling element bearing in the numerical solution ADINA system was used to prepare numerical models of junction. The results of the calculations of pressure distributions for changeable screw's span are shown graphically and the table of percentages of the load loss of contact between the surfaces A and B of slewing bearing screw connection.

Obecna sytuacja gospodarcza powoduje, że wiele obiektów budowlanych zmienia swoich właścicieli i konieczne jest dostosowanie istniejącej infrastruktury do wymagań nowego użytkownika. Modernizacja powoduje często przyrost obciążenia użytkowego lub modyfikację geometrii konstrukcji. Niejednokrotnie przebudowie nie musi ulegać cała konstrukcja, a jedynie jej poszczególne elementy, czego przykładem może być dołączenie wspornika stanowiącego podporę belki podsuwnicowej, do istniejącego w hali słupa żelbetowego.
The results of the experimental investigations of the corbels reinforced with steel double-headed studs connected with precast columns were introduced in the work. Cracks morphology and carrying capacity strongly depends on the kind of the interface between corbel and column. The carrying capacity of these corbels was calculated by means of ACI-318 provisions based on shear-friction theory.

Given a graph G and a vertex coloring c, G is called l-radio connected if between any two distinct vertices u and v there is a path such that coloring c restricted to that path is an l-radio coloring. The smallest number of colors needed to make G l-radio connected is called the l-radio connection number of G. In this paper we introduce these notions and initiate the study of connectivity through radio colored paths, providing results on the 2-radio connection number, also called L(2, 1)-connection number: lower and upper bounds, existence problems, exact values for known classes of graphs and graph operations.

Associated with - satisfying some particular conditions - local basis of TM local connection form of such a connection is an R(G)-valued 1-form build from the dual basis ω1, ω2 and from the local connection form ω of ▽. The structural equations of (M,∇) are equivalent to the condition dΩ-Ω∧Ω=0. This work was intended as an attempt to describe in a unified way the construction of similar 1-forms known for constant Gauss curvature surfaces, in particular of that given by R.

Opis:
The paper presents the results of experimental investigations into fatigue properties of metal and CFRP-composite glued joints. The object of investigation was adhesive joints between metal sheets made from iron alloy 30HGS (popular steel in the Polish aviation industry) and CFRP orthogonal reinforced sheets made from 10 layers of SIGRATEX CE3208 pre-preg. The main adhesive was the WK-3 glue (applied in the form of 0.2 mm thin foil) while the DP-490 - liquid epoxy glue was used as technological aid for specimen manufacturing. Two kinds of specimens were prepared and tested: single-lap joints and double-lap joints. The paper presents S-N curves for both kinds of those specimens. Besides fatigue life of the glued joints, the interest was focused on the NDT tests regarding damage propagation inside the glue-connection. The paper presents several C-scans made at different stages of fatigue testing. It has been found that the damage occurs almost equally in the whole volume of the glue layer (contrary to the expectation following from the physical model of the glue-connection internal loading). The results of experiments regarding thermal effect of cyclic loading of the glued joints are also described. It has been found that this effect could be used as an important parameter for diagnostics purposes of the glued joints.

Opis:
A path in an edge-colored (respectively vertex-colored) graph G is rainbow (respectively vertex-rainbow) if no two edges (respectively internal vertices) of the path are colored the same. An edge-colored (respectively vertex-colored) graph G is rainbow connected (respectively vertex-rainbow connected) if every two distinct vertices are connected by a rainbow (respectively vertex-rainbow) path. The rainbow connection number rc(G) (respectively vertex-rainbow connection number rvc(G)) of G is the smallest number of colors that are needed in order to make G rainbow connected (respectively vertex-rainbow connected). In this paper, we show that for a connected graph G and any edge e = xy ∈ E(G), rvc(G) ≤ rvc(G − e) ≤ rvc(G) + dG−e(x, y) − 1 if G − e is connected. For any two connected, non-trivial graphs G and H, rad(G□H)−1 ≤ rvc(G□H) ≤ 2rad(G□H), where G□H is the Cartesian product of G and H. For any two non-trivial graphs G and H such that G is connected, rvc(G ◦ H) = 1 if diam(G ◦ H) ≤ 2, rad(G) − 1 ≤ rvc(G ◦ H) ≤ 2rad(G) if diam(G) > 2, where G ◦ H is the lexicographic product of G and H. For the line graph L(G) of a graph G we show that rvc(L(G)) ≤ rc(G), which is the first known nontrivial inequality between the rainbow connection number and vertex-rainbow connection number. Moreover, the bounds reported are tight or tight up to additive constants.

Opis:
Modelling and calculations of an asymmetrical bolted flange connection at the operational stage are presented. The physical model of the joint is based on a flexible flange element that is connected with a rigid support by means of hybrid elements, which substitute bolts. Between the flange element and the support, the linear Winkler model of a contact layer is taken into account. The bolted flange connection is preloaded and then subjected to an eccentric normal load. The influence of nonlinearity of the contact layer between the joined elements on computational values of bolt forces has been investigated. Results of calculations for several different values of the joined element’s thickness are described.

Opis:
The current analysis raises the issue of the syntactic relations typology in contemporary Russian. The two complementary directions in the morphosyntactic research are discussed, which are the reductionist and the expansionist approaches. Following the formal syntactic criterion, the author introduces and then analyses thoroughly the opposition of two syntactic linkings: connection and innection. Connection is defined as a syntactic linking based on the primary linear co-occurrence of lexemes (as syntactems), while innection includes the adjustment of one element to the other, according to the formal grammatical rules. The presented analysis is illustrated by the linguistic material from contemporary Russian.
