Abstract:
The Siromoney matrix model is a simple and elegant model for describing two-dimensional digital picture languages. The notion of attaching indices to nonterminals in a generative grammar, introduced and investigated by Aho. is considered in the vertical phase of a Siromoney matrix grammar (SMG). The advantage of this study is that the new model retains the simplicity and elegance of SMG but increases the generative power and enables us to describe pictures not generable by SMG. Besides certain closure properties and hierarchy results. applications of these two-dimensional grammars to describe tilings, polyominoes, distorted patterns and parquet deformations are studied.

Abstract:
Honeycomb paperboard has been widely used in transportation and packaging of electronic instruments and furniture owing to the advantages of light weight, good compression resistance, environmental friendliness, and easy degradation. As a common cushioning material in transportation, it is worth studying the damping characteristic and vibration reduction mechanism of honeycomb paperboard. Based on the basic principles of vibration mechanics, the damping of honeycomb paperboard was proposed. Then the influences of cell length, paperboard thickness, grammage of core paper, and the honeycomb structures with face sheet or without face sheet on the damping characteristic of honeycomb paperboard were analyzed. Finally, the vibration reduction mechanism of packaging system with honeycomb paperboard and block was discussed briefly. The results show that the damping value of honeycomb paperboard decreases with the increase of cell length and paperboard thickness. The honeycomb paperboard with large grammage of core paper has high damping value, and yet paper honeycomb core structure without face sheet has poor damping capacity. What's more, the vibration reduction capacity of packaging system is influenced by the deformation and damping characteristic of honeycomb paperboard, among which material damping and structural damping contribute more, honeycomb deformation and air damping contribute less. The weight of block does not affect the damping characteristic of honeycomb paperboard, but affects the vibration reduction capacity of the whole system.

Abstract:
Aramid (AF), glass (GF), carbon (CF), basalt (BF), and flax (FF) fibers in the form of fabrics were used to produce the composites by hand-lay up method. The use of fabrics of similar grammage for composites’ manufacturing allowed for a comprehensive comparison of the properties of the final products. The most important task was to prepare a complex setup of mechanical and thermomechanical properties, supplemented by fire behavior analysis, and discuss both characteristics in their application range. The mechanical properties were investigated using tensile and flexural tests, as well as impact strength measurement. The investigation was improved by assessing thermomechanical properties under dynamic deformation conditions (dynamic mechanical–thermal analysis (DMTA)). All products were subjected to a fire test carried out using a cone calorimeter (CC).

Abstract:
AbstractMeasured local paper structure—i.e. local basis weight, local thickness, local density and local fiber orientation—has been linked to local strain and local material failure (local temperature increase due to energy dissipation upon fiber–fiber bond failure) measured during tensile testing. The data has been spatially linked through data map registration delivering several thousand $$1\times 1\,\hbox{mm}^2$$ 1 × 1 mm 2 paper regions, each containing all measured properties. The relation between local paper structure and resulting local deformation and failure is studied with regression models. Multiple linear regression modeling was used to identify the paper structure related drivers for local concentrations of strain under load and local concentrations of material failure, which are both starting to occur considerably before rupture of the paper. Analyzing the development of local strain in paper we found that regions with higher basis weight and higher fiber orientation in load direction tend to exhibit considerably lower strain during tensile testing. Furthermore, the relation between local strain and local grammage can be predicted with the statistical theory of elasticity. Also regions with higher density have lower local strain, but not as pronounced. The findings for local fiber–fiber bond failure of paper are similar but not equivalent. The strongest correlation exists with local grammage. Local density and local fiber orientation show in turn weaker correlation with local bond failure. Local variations in paper thickness were not relevant in any case. These findings are highlighting the relevance of local fiber orientation and local density variations as structural mechanisms governing paper failure. In the past the focus has been mostly on paper formation. Together with local grammage (formation) they are responsible for the weak spots in paper, and thus cause local concentrations of paper strain and the initiation of failure under tensile load.

Abstract:
Relevance of research. Under complex correction of speech disorders in existing orthodontic pathology, it is important to establish the causative factor, because incorrect tongue articulation, infantile type of swallowing and other bad habits can be the cause of dental and maxillary pathologies and, at the same time, speech disorders. The cause-and-effect relationship between dentoalveolar and speech disorders has been proved. Anomalies and deformations of the dentoalveolar apparatus prevent the sounds from being pronounced normally, contribute to strengthening the habits of improper articulation and complicate logopedic correction. The problem of logopedic correction of sound pronunciation should be addressed comprehensively in collaboration with an orthodontist. The purpose of the research. To treat patients with anomalies of bite and speech disorders according to the proposed algorithm. Materials and methods. To achieve study objectives, 82 patients with severe orthodontic pathology and speech disorders, with normal hearing and intellect, were accepted for treatment. Clinical examination according to the generally accepted scheme, extraoral and intraoral photographs, anthropometry, myography, cephalometry, and logopedic diagnostics of all aspects of speech were conducted. After establishing the diagnosis, determining the treatment plan, orthodontic treatment was performed simultaneously with speech therapy correction. Results and discussion. The first step in the algorithm of successful treatment (correction) of speech disorders and dentoalveolar anomalies was the explanation of its necessity. The second stage of the algorithm was a clinical examination, which included medical history taking and objective methods of examination. The speech therapy part of the algorithm provided for speech therapy diagnosis of all aspects of speech: sound pronunciation, vocabulary, grammar, phonetics. Additional methods of examination were performed for the preparation of the plan, the choice of method and tactics of treatment: extraoral and intraoral photographs, anthropometry, myography, cephalometry, which is an integral part of the second stage of the treatment algorithm for patients with abnormalities and deformations of the dentoalveolar device in conjunction with correction of speech disorders. The third stage of the algorithm was direct orthodontic treatment and speech correction. The retention period is the final stage of the algorithm for treating patients with abnormalities and deformations of the dental apparatus in combination with the correction of speech disorders. Conclusion. The algorithm for treating patients with anomalies of bite and speech disorders consists of the following blocks: motivation, detailed diagnosis, treatment planning and tactics, the active period of orthodontic treatment simultaneously with speech correction and patient management in the retention period.

Abstract:
The object of analysis in the provided article is the language-game as a method of representing the author’s vision. The content behind term “language-game” is revealed by an art space of A.I. Vvedensky, Russian poet of avant-gardism and philosopher. It is analyzed a distinction between children’s and adult’s works. The main content of the current study is an analysis of the most effective methods of language-game presentation in artistic communication of the poet, such as free verse, contamination of phraseological units, comparison, semantic indifference of lexemes, transformation of grammar categories, phrase deformation, etc. Based on the conducted research, a conclusion about specifics of the poet’s individual writing style can be made. In Vvedensky’s linguistic poetics, language-game manifests itself at different levels of text function as an important factor to text formation. It is important to note that language-game techniques found in his children’s works are aimed at building a positive dialog and are seen as a positive phenomenon, while his more mature works feature an abstract artistic world with abstract artistic meaning.

Abstract:
Abstract Nanocellulose network in the form of cellulose nanopaper is an important material structure and its time-dependent mechanical response is crucial in many of its potential applications. In this work, we report the influences of grammage and strain rate on the tensile response of bacterial cellulose (BC) nanopaper. BC nanopaper with grammages of 20, 40, 60 and 80 g m−2 were tested in tension at strain rates ranging from 0.1% s−1 to 50% s−1. At strain rates $$\le$$ ≤ 2.5% s−1, both the tensile modulus and strength of the BC nanopapers stayed constant at ~ 14 GPa and ~ 120 MPa, respectively. At higher strain rates of 25% s−1 and 50% s−1 however, the tensile properties of the BC nanopapers decreased significantly. This observed anomalous tensile response of BC nanopaper is attributed to inertial effect, in which some of the curled BC nanofibres within the nanopaper structure do not have enough time to uncurl before failure at such high strain rates. Our measurements further showed that BC nanopaper showed little deformation under creep, with a secondary creep rate of only ~ 10–6 s−1. This stems from the highly crystalline nature of BC, as well as the large number of contact or physical crosslinking points between adjacent BC nanofibres, further reducing the mobility of the BC nanofibres in the nanopaper structure.

Abstract:
This PhD thesis deals with the use of structural methods of objects identification for industrial robots operation. First, the present state of knowledge in the field is described, i.e. the whole process of objects recognition with the aid of common methods of the syntactic analysis. The main disadvantage of these methods is that is impossible to recognize objects whose digitalized image is corrupted in some ways (due to excessive noise or image disturbances), objects are therefore deformed. Further, other methods for the recognition of deformed objects are described. These methods use structural description of objects for object recognition, i.e. methods which determine the distance between attribute descriptions of images. The core part of this PhD thesis begins in Chapter 5, where deformation grammars, capable of description of all possible object deformations, are described. The only complication in the analysis is the ambiguity of the deformation grammar, which lowers the effectiveness of the analysis. Further, PhD thesis deals with the selection and modification of a proper parser, which is able to analyze a deformation grammar effectively. Three parsers are described: the modified Earley parser, the modified Tomita parser and the modified hybrid LRE(k) parser. As for the modified Earley’s parser, ways of its effective implementation are described. One of the necessary parts of the object recognition is providing the invariances, which this PhD thesis covers in detail, too. Finally, the results of described algorithms are mentioned (successfulness and speed of deformed objects recognition) and suggested testing environment and implemented algorithms are described. In conclusion, all determined possibilities of deformation grammars and their results are summarized.
