Abstract:
In recent era, today a many firms share their service/product descriptions. With that, many meaningful information in the textual form is hidden under the unstructured text. Algorithms like information extraction enable the identification of structured relations and they does not produce an optimal result and it is much costlier to operate with headlines of a text which has no examples of the target structured information. We propose a new approach which facilitates the formation of a structured metadata by recognizing documents which are likely to have some type and this information is to be subsequently used for both segregation and search process. Our approach is based on an idea that some attributes of a text will match with the query object which acts as identifier both for segregation as well as for storage and retrieval. Our implementation results show that our approach provides some superior results than existing approaches which rely only on query content or on textual information, to discover the key attributes.

Abstract:
Abstract A column EnKF, based on the Canadian global EnKF and using the RTTOV radiative transfer (RT) model, is employed to investigate issues relating to the EnKF assimilation of Advanced Microwave Sounding Unit-A (AMSU-A) radiance measurements. Experiments are performed with large and small ensembles, with and without localization. Three different descriptions of background temperature error are considered: 1) using analytical vertical modes and hypothetical spectra, 2) using the vertical modes and spectrum of a covariance matrix obtained from the global EnKF after 2 weeks of cycling, and 3) using the vertical modes and spectrum of the static background error covariance matrix employed to initiate a global data assimilation cycle. It is found that the EnKF performs well in some of the experiments with background error description 1, and yields modest error reductions with background error description 3. However, the EnKF is virtually unable to reduce the background error (even when using a large ensemble) with background error description 2. To analyze these results, the different background error descriptions are viewed through the prism of the RT model by comparing the trace of the matrix , where is the RT model and is the background error covariance matrix. Indeed, this comparison is found to explain the difference in the results obtained, which relates to the degree to which deep modes are, or are not, present in the different background error covariances. The results suggest that, after 2 weeks of cycling, the global EnKF has virtually eliminated all background error structures that can be “seen” by the AMSU-A radiances.

Abstract:
We study Darboux transformations for the two boson (TB) hierarchy both in the scalar as well as in the matrix descriptions of the linear equation. While Darboux transformations have been extensively studied for integrable models based on SL (2, R) within the AKNS framework, this model is based on SL (2, R)⊗ U (1). The connection between the scalar and the matrix descriptions in this case implies that the generic Darboux matrix for the TB hierarchy has a different structure from that in the models based on SL (2, R) studied thus far. The conventional Darboux transformation is shown to be quite restricted in this model. We construct a modified Darboux transformation which has a much richer structure and which also allows for multi-soliton solutions to be written in terms of Wronskians. Using the modified Darboux transformations, we explicitly construct one-soliton/kink solutions for the model.

Abstract:
This paper investigates the process of integrating descriptions of static structures in the form of charts and specifications at the stage of conceptual modeling of automated systems, that are developed to solve design tasks. In the process of creating an automated system based on the methodology for automating intellectual labor (MAIL), models of design tasks are formed: initial, conceptual, infological and datalogical. The conceptual model describes the system of concepts of the subject area. The description of conceptual model representation includes specifications and charts: for a static component - F1 and F2, the chart of conceptual structure; for a dynamic component - F3 and F4, the chart depicting a system of subject dependences; F6 and the matrix chart showing the model as a whole including static and dynamic components coordination. The features of constructing diagrams and forming specifications in the formation of a conceptual structure are studied, on the basis of which the method and technique to integrate descriptions of static components for the system of concepts of the subject area are determined. The article is given the integration of descriptions in the form of diagrams and specifications for the static components of conceptual model representations.

Full text
Abstract:
This paper challenges the concept of matrix, base or basic language used in many descriptions and models of insertional code-switching. It proposes an account based on Construction Grammar and usage-based principles. At the heart of the paper is a discussion of four problematic issues of matrix-language approaches: the unitary conception of the notion of language, the generalization that syntactic frames mirror languages, the missing independent evidence for a matrix language and the narrow scope of the models that employ this term. The proposed approach of Bilingual Construction Grammar instead operates with a more complex, usage-based concept of language affiliation and places constructions in the centre of speech production. It thus avoids too coarse global predictions in favour of construction-specific predictions. This way, the matrix-language effect can be reinterpreted as by-product of constructional processing. Instead of using the term matrix language it is thus more appropriate to speak of matrix constructions.

Abstract:
Finite Element based micromechanical methods are used to study the influence of microscale phase arrangements on the overall and microscale thermomechanical properties of two advanced two-phase materials, duplex steels and unidirectional continuously reinforced metal matrix composites (MMCs). Both inclusion-matrix topologies and interwoven microgeometries are investigated for duplex steels, and the predicted macroscopic transverse elastoplastic responses are correlated with quantitative stereological descriptions of the microgeometries. For the MMCs, the emphasis is put on the influence of the fiber arrangement on the microscale residual stress states of the as-produced material and on their effects on damage mechanisms.

Abstract:
This chapter was originally presented to a mixed audience of physicists and mathematicians with some basic working knowledge of random matrix theory. The first part is devoted to the solution of the chiral Gaussian unitary ensemble in the presence of characteristic polynomials, using orthogonal polynomial techniques. This includes all eigenvalue density correlation functions, smallest eigenvalue distributions, and their microscopic limit at the origin. These quantities are relevant for the description of the Dirac operator spectrum in quantum chromodynamics with three colors in four Euclidean space-time dimensions. In the second part these two theories are related based on symmetries, and the random matrix approximation is explained. In the last part recent developments are covered, including the effect of finite chemical potential and finite space-time lattice spacing, and their corresponding orthogonal polynomials. This chapter also provides some open random matrix problems.

Abstract:
Students of geology who may have only a modest background in mathematics need to become familiar with the theories of stress, strain, and other tensor quantities, so that they can follow, and apply to their own research, developments in modern, quantitative geology. This book, based on a course taught by the author at UCLA, can provide the proper introduction. Included throughout the eight chapters are 136 complex problems, advancing from vector algebra in standard and subscript notations, to the mathematical description of finite strain and its compounding and decomposition. Fully worked solutions to the problems make up the largest part of the book. With their help, students can monitor their progress, and geologists will be able to utilize subscript and matrix notations and formulate and solve tensor problems on their own. The book can be successfully used by anyone with some training in calculus and the rudiments of differential equations.

Abstract:
Mobile computing is getting more and more attention these days, but the fact that there is still inadequate source of development methodologies to support mobile development, triggers the interest in this study to explore issues related to mobile development methodologies. The mobile developers are facing formidable challenges in the development of mobile application due to the specific demand and technical constraints of mobile environment. Selecting a suitable development methodology is believed to be the key answer to all these issues. Thus, this study aimed to propose a solution to resolve the issues. A decision matrix based on Pugh method was constructed to assist mobile developers especially the novices, to choose the methodology that suits the requirements of their mobile development projects. In order to rate the usefulness of the constructed matrix, an electronic version of the matrix was designed and developed, called md-Matrix. Detail descriptions of the processes involved in constructing the matrix and designing the electronic version of the constructed matrix are also described. Analysis of data gathered from a questionnaire given after the test of md-Matrix shows that participants fairly agreed that md-Matrix is useful in helping them to develop a mobile application.

Abstract:
This article provides a comprehensive overview of the machining of aluminum alloys, composites, and ceramics at micro scale. All major aspects of the micromachining of aluminum alloys including process descriptions, key research findings, applications, major challenges, and guidelines for future research have been covered in this article. Based on the literature, conventional micromachining processes, such as turning, milling, grinding, and drilling, have been found to be suitable for machining most of the cast and wrought aluminum alloys. On the other hand, nonconventional micromachining processes were approached for the micromachining of aluminum metal matrix composites and alumina ceramics. Some challenges and aspects in the area of micromachining of aluminum alloys that need future considerations are burr formation, tool wear, surface finish, microstructures and properties changes, and process development for advanced and hybrid micromachining.

Abstract:
The purpose of this study was to explore the contributions of the vision community-based rehabilitation association (VCBRA) in early intervention programs in Ambo, Ethiopia. In this case study, a total of 18 respondents, consisting of the VCBRAs’ staff, such as the program director, the manager, social workers, beneficiaries, and participants from partners’ institutions, such as Ambo branch organizations of persons with disabilities, Ambo University, Ambo town social affairs office, were participated in the study as sources of data. Data were collected through document analysis, interview, and close-ended questionnaire. The quantitative data were analyzed using descriptive statistics, such as frequency, percentage, and mean. In addition, data from document analysis and interviews were analyzed thematically and supplemented by narrative descriptions and verbatim quotations. The effectiveness of VCBRA intervention programs were assessed using a CBR matrix, and the finding uncovered that VCBRA intervention programs were found to be effective in general. Specifically, VCBRA seems to be more effective in the three intervention areas, such as health, education, and livelihood components, while empowerment and social components of rehabilitation programs were less focused. In addition, children and youths with different disabilities, parents of children with disabilities, and poor families were beneficiaries of VCBRA intervention programs. Further, lack of trained and diversified staff, lack of financial resources, low parent involvements, and the negative impact of COVID-19 were identified as the main challenges hindering the implementation of early intervention programs provided by the VCBRA.

Abstract:
The classical idea of an instructional process is to create some new knowledge, skills and abilities, so-called KSAs. If a student has a set of KSAs at the beginning of a learning process and if he or she has a new set of them at the end of a learning period we can say the instructional activity transforms the student from the starting state (state number 1) to the final state (state number 2). One can define such transformation as an effective action. It is possible to describe each action as a set of external impacts. In the case when this set is a series of standard actions, which usually give a predicted result, we can say it is a traditional education technology in so-called triad form: object number 1 transfers into object number 2. It is possible to present this in the form of a matrix equation. This equation is the main one in the general theory of technologies. The main idea of this article is to analyze the effectiveness of an instructional process based on mathematical descriptions, which was developed in the general theory of technologies.

Abstract:
The interest in quantum information processing has given rise to the development of programming languages and tools that facilitate the design and simulation of quantum circuits. However, since the quantum theory is fundamentally based on linear algebra, these high-level languages partially hide the underlying structure of quantum systems. We show that in certain cases of practical interest, keeping a handle on the matrix representation of the quantum systems is a fruitful approach because it allows the use of powerful tools of linear algebra to better understand their behavior and to better implement simulation programs. We especially focus on the Joint EigenValue Decomposition (JEVD). After giving a theoretical description of this method, which aims at finding a common basis of eigenvectors of a set of matrices, we show how it can easily be implemented on a Matrix-oriented programming language, such as Matlab (or, equivalently, Octave). Then, through two examples taken from the quantum information domain (quantum search based on a quantum walk and quantum coding), we show that JEVD is a powerful tool both for elaborating new theoretical developments and for simulation.

Abstract:
This chapter presents performance of a new technique for constructing Quasi-Cyclic Low-Density Parity-Check (QC-LDPC) encrypted codes based on a row division method. The new QC-LDPC encrypted codes are flexible in terms of large girth, multiple code rates, and large block lengths. In the proposed algorithm, the restructuring of the interconnections is developed by splitting the rows into subrows. This row division reduces the load on the processing node and ultimately reduces the hardware complexity. In this method of encrypted code construction, rows are used to form a distance graph. They are then transformed to a parity-check matrix in order to acquire the desired girth. In this work, matrices are divided into small sub-matrices, which result in improved decoding performance and reduce waiting time of the messages to be updated. Matrix sub-division increases the number of sub-matrices to be managed and memory requirement. Moreover, Prototype architecture of the LDPC codes has been implemented by writing Hardware Description Language (VHDL) code and targeted to a Xilinx Spartan-3E XC3S500E FPGA chip.

Four main methods allowing for the reduction of memory usage and computational complexity are presented: hierarchical grids, tiles, and two techniques based on the indirect addressing (the fluid index array and the connectivity matrix). For parallel implementations, the advantages and disadvantages of the different methods of domain decomposition and workload balancing are discussed.

Abstract:
Understanding the cellular principles of odontogenesis requires an incremental and up-to-date understanding of the sequential molecular embryological processes leading to a complete normal dental formation. This topic review provides a state-of-the-art explanation of these dental morphogenetic processes and the subsequent crown development in normal deciduous and permanent teeth, based on an upgraded version of the “odontogenic homeobox code”. The description of these processes is shown from the differential epithelium-ectomesenchyme and epithelium-mesenchyme interaction stand-points, necessary to produce cell-cell and extracellular matrix-cell transformations. These cellular processes lead to the sequential stages of classic histological dental formation, which progressively correspond to the development of dental regions, identities, and forms, to obtain complete deciduous and permanent human dentitions.

Abstract:
This study presents the application of a novel, discrete modeling framework for composite materials made via 3-D printing of continuous fibers. Fiber tows are explicitly modeled as Timoshenko beam elements, and the matrix is represented via tetrahedral elements derived from the set of beam nodes. The constitutive law of the matrix is defined at facets which are generated from the tessellation process in the mesh. Vectoral representation of stress and strain on facets provides clear and physics-based material descriptions. A computationally efficient, robust, and highly parallelized scheme is provided to generate the 3-D printed composite parts, which can attain the fiber volume fractions higher than 60 %. The calibration result of the model applied to the 3-D printing composite materials is presented, which demonstrates the capability of the model in capturing the main damage mechanisms of 3D printed composites.

Full text
Abstract:
Microstructual studies suggest that in some tissues, collagen fibers are approximately normally distributed about a mean preferred fiber direction. Structural constitutive equations that account for this dispersion of fibers have been shown to capture the mechanical complexity of these tissues quite well. However, such descriptions are computationally cumbersome for two-dimensional fiber distributions, let alone for fully three dimensional fiber populations. We have developed a new constitutive law for such tissues, based on a novel invariant theory for dispersed transverse isotropy. The model is polyconvex and fits biaxial data for aortic valve tissue as accurately as the standard structural model. Modification of the fiber stress-strain law requires no re-formulation of the constitutive tangent matrix, making the model flexible for different types of soft-tissues. Most importantly, the model is computationally expedient in a finite element analysis.

Full text
Abstract:
Dynamic simulation of the operation of a compressor station requires mathematical modelling of the dynamic behaviour of the compressor unit and various piping elements. Such models consist of large systems of non-linear partial differential equations describing the pipe flow together with non-linear algebraic equations describing the quasi-steady flow through various valves, constrictions and compressors. In addition, the models also include mathematical descriptions of the control system which consists of mixed algebraic and ordinary differential (mad) equations with some inequalities representing controllers’ limits. In this paper a numerical technique for the solution of the gas dynamics equations is described, which is based on the transfer matrix formulation relating the state vector time-difference at one side of an element to that on the other side. This approach facilitates incorporation of all elements transfer matrices into an overall transfer matrix according to the system geometrical connectivity. The paper also presents simulation results and comparison with actual field measurements of three case histories: 1) simulation of a compressor surge protection control process; 2) unit startup; and 3) slow transient of a compressor station responding to changes in the discharge pressure set point. Good agreement between simulation results and field measurements is demonstrated.

Abstract:
Ab initio calculation was performed to investigate the nature of Si-Al bonding in Al based alloys. Total electronic energy Etot for different configurations of the model cluster Si2Al6 was calculated. When the model cluster consists of two perfect tetrahedrons there is a strong influence of the Si-Si distance on the Si-Al adiabatic potential. The equilibrium distance between Si and Al atoms increases with the length of Si-Si bond increasing. It was concluded that description of Si clusters in Al matrix demands an account of the angle depending part of Si-Al interaction.

Abstract:
Attention to mixed methods studies research has increased in recent years, particularly among funding agencies that increasingly require a mixed methods approach for program evaluation. At the same time, researchers operating within large-scale, rapid-turnaround research projects are faced with the reality that collection and analysis of large amounts of qualitative data typically require an intense amount of project resources and time. However, practical examples of efficiently collecting and handling high-quality qualitative data within these studies are limited. More examples are also needed of procedures for integrating the qualitative and quantitative strands of a study from design to interpretation in ways that can facilitate efficiencies. This paper provides a detailed description of the strategies used to collect and analyze qualitative data in what the research team believed to be an efficient, high-quality way within a team-based mixed methods evaluation study of science, technology, engineering, and math (STEM) high-school education. The research team employed an iterative approach to qualitative data analysis that combined matrix analyses with Microsoft Excel and the qualitative data analysis software program ATLAS.ti. This approach yielded a number of practical benefits. Selected preliminary results illustrate how this approach can simplify analysis and facilitate data integration.
