description: Recent studies have developed tunable topological elastic metamaterials to maximize performance in the presence of varying external conditions, adapt to changing operating requirements, and enable new functionalities such as a programmable wave path. However, a challenge remains to achieve a tunable topological metamaterial that is comprehensively adaptable in both the frequency and spatial domains and is effective over a broad frequency bandwidth that includes a subwavelength regime. To advance the state of the art, this research presents a piezoelectric metamaterial with the capability to concurrently tailor the frequency, path, and mode shape of topological waves using resonant circuitry. In the research presented in this manuscript, the plane wave expansion method is used to detect a frequency tunable subwavelength Dirac point in the band structure of the periodic unit cell and discover an operating region over which topological wave propagation can exist. Dispersion analyses for a finite strip illuminate how circuit parameters can be utilized to adjust mode shapes corresponding to topological edge states. A further evaluation provides insight into how increased electromechanical coupling and lattice reconfiguration can be exploited to enhance the frequency range for topological wave propagation, increase achievable mode localization, and attain additional edge states. Topological guided wave propagation that is subwavelength in nature and adaptive in path, localization, and frequency is illustrated in numerical simulations of thin plate structures. Outcomes from the presented work indicate that the easily integrable and comprehensively tunable proposed metamaterial could be employed in applications requiring a multitude of functions over a broad frequency bandwidth.

description: Shrinkage Compensating Concrete (Class S) is made with an expansive cement in which the expansion, if restrained, induces compressive stresses that approximately offset tensile stresses induced during drying shrinkage, thereby eliminating or significantly reducing the occurrence of shrinkage cracking in concrete. The objectives of this study were to evaluate the construction and performance of the Shrinkage Compensating Concrete (Class S) and to compare these characteristics to previous Class S concrete data and to conventional Class AA bridge deck concrete. This report summarizes construction activities and provides final performance evaluations and recommendations relative to experimental decks and barrier walls constructed of shrinkage compensating concrete during the widening and reconstruction of 1·75 in Kenton County, Kentucky.

description: In this paper we extend categorically the notion of a finite nilpotent group to fusion categories. To this end, we first analyze the trivial component of the universal grading of a fusion category C, and then introduce the upper central series of C. For fusion categories with commutative Grothendieck rings (e.g., braided fusion categories) we also introduce the lower central series. We study arithmetic and structural properties of nilpotent fusion categories, and apply our theory to modular categories and to semisimple Hopf algebras. In particular, we show that in the modular case the two central series are centralizers of each other in the sense of M. Muger.

description: Many workers at the production department of Libyan Textile Company work with different performances. Plan of company management is paying the money according to the specific performance and quality requirements for each worker. Thus, it is important to predict the accurate evaluation of workers to extract the knowledge for management, how much money it will pay as salary and incentive. For example, if the evaluation is average, then management of the company will pay part of the salary. If the evaluation is good, then it will pay full salary, moreover, if the evaluation is excellent, then it will pay salary plus incentive percentage. Twelve variables with 121 instances for each variable collected to predict the evaluation of the process for each worker. Before starting classification, feature selection used to predict the influential variables which impact the evaluation process. Then, four algorithms of decision trees used to predict the output and extract the influential relationship between inputs and output. To make sure get the highest accuracy, ensemble algorithm (Bagging) used to deploy four algorithms of decision trees and predict the highest prediction result 99.16%. Standard errors for four algorithms were very small; this means that there is a strong relationship between inputs (7 variables) and output (Evaluation). The curve of (Receiver operating characteristics) for algorithms gave a high-level specificity and sensitivity, and Gain charts were very close to together. According to the results, management of the company should take a logic decision about the evaluation of production process and extract the important variables that impact the evaluation.

description: Pyrament Blended Cement (PBC) is a high performance cement that was developed by Lone Star Industries. Concrete that is made with PBC is rapid setting, has high strength and low permeability. The Kentucky Transportation Cabinet chose to use PBC concrete in a lull·depth bridge deck. The objectives of this study were to evaluate the construction and performance of a full-depth bridge deck constructed of PBC concrete and to compare the data obtained to historical construction and performance properties of conventional, Class AA bridge deck concrete. This report provides information relative to construction activities, materials properties, and a summary of the three-year performance of the experimental bridge deck.
Use of Class AA Concrete Modified with a High-Range Water Reducing Admixture in a Full-Depth Bridge Deck Slab US 127, Lincoln County

description: Because it is desirable for bridge deck concrete to be strong and durable, the Kentucky Department of Highways chose to use a high-range water reducer to modify the properties of a conventional Class AA concrete mixture to be placed in a full-depth concrete bridge deck on US 127 in Lincoln County. A high-range water reducer is a chemical admixture that when added to low-to-normal slump concrete produces a high slump to flowing concrete. The higher slump enhances placement properties in areas of closely spaced and congested reinforcing steel such as that encountered in the corners of a skewed bridge structure. The addition of a high-range water reducer permits reductions in mix water in the range of 12 to 30 percent. The reduction in mix water lowers the water-to-cement ratio leading to increased strength properties. The Kentucky Department of Highways specified an admixture dosage rate of 10.42 mL per kilogram of cement (16.0 oz per 100 lbs of cement). Test results indicated that this dosage rate would facilitate the desired 15 percent reduction in the available mix water.  The use of a high-slump concrete enhances placement properties in areas of closely spaced reinforcing steel such as a skewed bridge structure. Data obtained during this study indicate that the high-range water reducing admixture also enhances durability and strength properties of concrete. The magnitude of cracking was slightly more for the experimental deck concrete but the severity of the cracks appeared to be higher in the control deck. The inability to adhere to the specified admixture rate compounded by the finishing characteristics of the concrete mixture contributed to the poor results achieved with the experimental deck. The admixture representative present during the experimental deck placement could not provide the suitable proportioning of the admixtures necessary for both a good finishing mix that also met the requirements of the project.  It is recommended that consideration be given again to the use of high-range water reducers to modify conventional bridge deck concrete in situations where the placement properties can be enhanced or where it is desired to enhance strength and durability properties. The positive attributes of the modified concrete identified in this project make it worthwhile to gain additional experience with the use of these admixtures. It is recommended the specifications be revised for any future projects to require that trial batches be performed until two separate batches conform to all specification requirements and that the bridge contractor have his intended placement and finishing personnel at the trial placements to gain experience.
Similar but different: the varied landscape of Onfp/Oef stars variability

description: The Oef category gathers rapidly rotating and evolved O-stars displaying a centrally reversed He II 4686 emission line. The origin of the variability of their photospheric and wind spectral lines is debated, with rotational modulation or pulsations as the main contenders. To shed new light on this question, we analysed high-quality and high-cadence TESS photometric time series for five Oef stars. We also collected a new time series of spectra for one target (lambda Cep) which had been the subject of specific debates in the last years. These observations reveal the variety of Oef behaviours. While space-based photometric data reveal substantial red noise components in all targets, only zeta Pup seems to display a long-lived periodicity. In our sample, stars exhibit a dominant signal at low frequencies but it appears relatively short-lived. This is reminiscent of rotational modulations by transient photospheric spots, though this scenario is challenged by the case of HD 14442, whose 1.230 d$^{-1}$ signal significantly exceeds the critical rotational frequency. In parallel, no evidence of persistent p-mode non-radial pulsations is found in either photometry or spectroscopy of the stars, only temporary excitation of g-mode pulsations could offer an alternative explanation for the dominant signals. Finally, the revised luminosities of the stars using GAIA-DR2 show that they are not all supergiants as zeta Pup. The question then arises whether the Oef peculiarity denotes a homogeneous class of objects after all.

description: • Issues perceived to be the most controversial were topics from the 20th century. • Teachers’ views on history are often not reflective; epistemic cognition is influenced by epistemic aims and is also topic specific. • It is important to concentrate on more complex epistemological interpretation schemata concerning history and learning and the connections between them in teacher training. Purpose: The purpose of this study was to discover topics in history education in Estonia that are perceived to be controversial, and to analyse how teachers’ epistemic cognition is reflected in the teaching of issues perceived to be controversial. Design/methodology/approach: Qualitative research based on group and individual interviews with 12 teachers, plus data from lesson observations among 10 participants. Findings: Issues perceived to be the most controversial are topics from the 20th century. The reflection of epistemic cognition in practice is a result of a complex interplay between knowledge and knowing related beliefs and processes. Research limitations: The small number of participants (12). Developed categories must be considered with caution as exploratory findings

description: Numerical calculations simulate transport experiments in carbon nanotube quantum dots (P. Jarillo-Herrero et al., Nature 434, 484 (2005)), where a strongly enhanced Kondo temperature T_K ~ 8K was associated with the SU(4) symmetry of the Hamiltonian at quarter-filling for an orbitally double-degenerate single-occupied electronic shell. Our results clearly suggest that the Kondo conductance measured for an adjacent shell with T_K ~ 16K, interpreted as a singlet-triplet Kondo effect, can be associated instead to an SU(4) Kondo effect at half-filling. Besides presenting spin-charge Kondo screening similar to the quarter-filling SU(4), the half-filling SU(4) has been recently associated to very rich physical behavior, including a non-Fermi-liquid state (M. R. Galpin et al., Phys. Rev. Lett. 94, 186406 (2005)).

description: • In Social Sciences, subject content needs to be related to students’ experiences and knowledge. • In secondary school, the language used to construct knowledge is abstract, dense, and complex. • The concept of Third space (Bhabha,1994) revealed problems with teaching and teachers’ perceptions of L2 students’ needs. • Education here appears as a space for a restricted curriculum with Swedish as the gatekeeper. • This shows that subject teachers need to learn linguistic aspects of their own subject. Purpose: The aim is to analyse linguistic aspects of education in Social Sciences for L2 students. Method: Lingustic ethnography is used for studying the hybridity of Social Sciences with material from nine lesson observations and interviews with three teachers. Findings: Findings showed that students’ earlier experiences, knowledge, and perspectives on life were not acknowledged. The Third space appears as a transitional space where students are perceived as deficient, not yet reaching the goal of the introduction programme: to enter mainstream education. Students’ agency was related to this space where the transformation was expected to take place, while teachers positioned themselves as outside, and the knowledge presented was simplified and fragmentized. While teachers expressed dissatisfaction with students’ (lacking) Swedish proficiency, they did not seem to understand their own role to teach Swedish through Social Sciences. Implications: This shows that subject teachers need to learn linguistic aspects of their own subject and conditions for L2 students’ learning.

description: • The European dimension in education was formed as a multilateral project of the Council of Europe and the European Union to improve European integration processes. • From the scholarly perspective, the development of the European dimension in education in Croatia is analysed from 1996 until 2020 • Political praxiology of education is introduced as a possible theoretical framework for future development. Purpose: This paper aims to present the twenty-five-year evolving pathway of the European dimension in education in Croatia. Furthermore, the paper critically problematises the lack of a theoretical framework that has marked this concept's research and partly contributed to its conceptual dispersion and scholarly ambiguity. Design: The paper design is based on chronological and content analysis of the European dimension in education development, primarily focusing on the Croatian context. The period analysed is from 1996, when the first paper on the European dimension in education in Croatia was published until 2020. Findings: The development frame of the European dimension in education is proposed, with an overview of appurtenant phases, followed by chronological and detailed elaborated thematic groups. As an answer to detected theoretical deficiencies, the political praxiology of education is introduced as a direction of its future theoretical development and a partly new shift in the conceptual definition of the European dimension in education is proposed.

Rheology and processability of teflon FEP resins for wire coating
Creators: name: Rozenbaoum, Evgueni E.
Publisher: name: University of British Columbia
Year: 2009

description: Experiments were carried out in both parallel plate and capillary rheometers for a variety of tetrafluoroethylene/hexafluoropropylene (TFE/HFP) copolymers and TFE/HFP/per-fluoro(alkyl vinyl ether) (TFE/HFP/PAVE) terpolymers, also known as Teflon® FEP polymers, having different molecular weights and compositions (HFP and PAVE content). The critical conditions for the onset of melt fracture and the influence of temperature, molecular weight, and composition of the resins are determined. The critical molecular weight for the onset of entanglements was found to be about 100,000, a value much higher than those previously reported. The relationships between the processability of the wire coating Teflon® FEP resins and their composition, viscosity, ability to crystallize, and melt elasticity were established. The experimental data were used for a thorough rheological modeling of the behavior of these resins. The latter includes calculation of their linear relaxation time spectra and nonlinear parameters using a multimode Phan-Thien and Tanner (PTT) constitutive equation. A new data analysis procedure based on a mathematical model for the nonisothermal capillary flow of polymer melts coupled with heat transfer is developed. The computer simulations proposed can be used to provide detailed velocity, temperature, and pressure distributions and to recover the parameters of the employed slip velocity model corrected for the effect of viscous heating. Finally, the effect of various processing aids on the processability of fluoropolymers and polyolefins during extrusion and wire coating was studied. It was found that polyethylene works as a processing aid in the extrusion of Teflon® FEP resins in the same way as fluoropolymers do in the extrusion of polyolefins. Finally, the processing additive based on a boron nitride (BN) composition was found to eliminate sharkskin melt fracture and postpone gross melt fracture to significantly higher shear rates for a variety of polymers.

description: Progressive Hedging is a popular decomposition algorithm for solving multi-stage stochastic optimization problems. A computational bottleneck of this algorithm is that all scenario subproblems have to be solved at each iteration. In this paper, we introduce randomized versions of the Progressive Hedging algorithm able to produce new iterates as soon as a single scenario subproblem is solved. Building on the relation between Progressive Hedging and monotone operators, we leverage recent results on randomized fixed point methods to derive and analyze the proposed methods. Finally, we release the corresponding code as an easy-to-use Julia toolbox and report computational experiments showing the practical interest of randomized algorithms, notably in a parallel context. Throughout the paper, we pay a special attention to presentation, stressing main ideas, avoiding extra-technicalities, in order to make the randomized methods accessible to a broad audience in the Operations Research community.

description: We investigate electron and ion surface states of a negatively charged dust particle in a gas discharge and identify the charge of the particle with the electron surface density bound in the polarization-induced short-range part of the particle potential. On that scale, ions do not affect the charge. They are trapped in the shallow states of the Coulomb tail of the potential and act only as screening charges. Using orbital-motion limited electron charging fluxes and the particle temperature as an adjustable parameter, we obtain excellent agreement with experimental data.

description: This dissertation examines part of the ground and polished stone tools from Toumba, Thessaloniki. The material comes from the deposits of three buildings on top of the hill (buildings Z, H, M), dated on Middle and Late Bronze Age. Some of the goals are the examination of raw material acquisition, tool production and use. These questions are approached through the study of typological and morphological characteristics, use-wear analysis and petrographical study by thin-section analysis. The data obtained are then examined in their archaeological context in order to understand the ways in which their manufacture and consumption were structured within the daily lives of the site's inhabitants.

description: Shock parameters at Earth's bow shock in rare instances can approach the Mach numbers predicted at supernova remnants. We present our analysis of a high Alfvén Mach number ($M_A= 27$) shock utilizing multipoint measurements from the Magnetospheric Multiscale (MMS) spacecraft during a crossing of Earth's quasi-perpendicular bow shock. We find that the shock dynamics are mostly driven by reflected ions, perturbations that they generate, and nonlinear amplification of the perturbations. Our analyses show that reflected ions create modest magnetic enhancements upstream of the shock which evolve in a nonlinear manner as they traverse the shock foot. They can transform into proto-shocks that propagate at small angles to the magnetic field and towards the bow shock. The nonstationary bow shock shows signatures of both reformation and surface ripples. Our observations indicate that although shock reformation occurs, the main shock layer never disappears. These observations are at high plasma $β$, a parameter regime which has not been well explored by numerical models.

description: • The mind and intelligence games can be used as an effective instrument for teaching some skills included in the social studies curriculum such as historical empathy, thinking, problem solving and decision-making skills. • Teacher candidates were both excited and concerned about using mind and intelligence games for social studies education. • To increase the professional self-confidence of social studies teachers, in-service teacher training can be enriched with workshop activities on mind game training and practices. Purpose: The study aims at analyzing teacher candidates’ experience and views about the use of mind and intelligence games in social studies courses. Design/methodology/approach: The basic qualitative design was used in this paper. Data were obtained during the 2016-2017 academic year from 12 4th year college students studying social studies teacher education in a university located in Turkey. A two-week (16 hours) workshop program on 21 different mind and intelligence games of different genres was given to the teacher candidates. Dataset were analyzed regarding the usability of mind and intelligence games in social studies education. Findings: The obtained results showed that although mind and intelligence games offer important contributions to teaching social studies, there may be some difficulties. Practical implications: University administrators may organise in-service training programs for instructors on mind and intelligence games as implementing them in courses may increase learner satisfaction and contribute to a more positive classroom environment.

Probability assignment in a quantum statistical model

description: The evolution of a quantum system, appropriate to describe nano-magnets, can be mapped on a Markov process, continuous in $β$. The mapping implies a probability assignment that can be used to study the probability density (PDF) of the magnetization. This procedure is not the common way to assign probabilities, usually an assignment that is compatible with the von Neumann entropy is made. Making these two assignments for the same system and comparing both PDFs, we see that they differ numerically. In other words the assignments lead to different PDFs for the same observable within the same model for the dynamics of the system. Using the maximum entropy principle we show that the assignment resulting from the mapping on the Markov process makes less assumptions than the other one. Using a stochastic queue model that can be mapped on a quantum statistical model, we control both assignments on compatibility with the Gibbs procedure for systems in thermal equilibrium and argue that the assignment resulting from the mapping on the Markov process satisfies the compatibility requirements.

description: Traditional statistical and measurements are unable to solve all industrial data in the right way and appropriate time. Open markets mean the customers are increased, and production must increase to provide all customer requirements. Nowadays, large data generated daily from different production processes and traditional statistical or limited measurements are not enough to handle all daily data. Improve production and quality need to analyze data and extract the important information about the process how to improve. Data mining applied successfully in the industrial processes and some algorithms such as mining association rules, and decision tree recorded high professional results in different industrial and production fields. The study applied seven algorithms to analyze production data and extract the best result and algorithm in the industry field. KNN, Tree, SVM, Random Forests, ANN, Naïve Bayes, and AdaBoost applied to classify data based on three attributes without neglect any variables whether this variable is numerical or categorical. The best results of accuracy and area under the curve (ROC) obtained from Decision tree and its ensemble algorithms (Random Forest and AdaBoost). Thus, a decision tree is an appropriate algorithm to handle manufacturing and production data especially this algorithm can handle numerical and categorical data.

description: We propose a new physical implementation of spin qubits for quantum information processing, namely defect states in antidot lattices defined in the two-dimensional electron gas at a semiconductor heterostructure. Calculations of the band structure of a periodic antidot lattice are presented. A point defect is created by removing a single antidot, and calculations show that localized states form within the defect, with an energy structure which is robust against thermal dephasing. The exchange coupling between two electrons residing in two tunnel-coupled defect states is calculated numerically. We find results reminiscent of double quantum dot structures, indicating that the suggested structure is a feasible physical implementation of spin qubits.

description: Στόχος της εν λόγω εργασίας είναι να διερευνήσει τις αλλαγές στις στάσεις μαθητών και μαθητριών Δευτεροβάθμιας εκπαίδευσης στην προώθηση της ισότητας των φύλων στο σχολείο. Αυτές οι αλλαγές καταγράφηκαν μετά τη διδακτική παρέμβαση στο μάθημα της Λογοτεχνίας. Η συγκεκριμένη παρέμβαση, εστίασε στην προώθηση της γυναικείας εμπειρίας και πιο συγκεκριμένα της ηθικής της φροντίδας μέσα από την έρευνα δράσης. Η παρέμβαση έδειξε ότι οι μαθήτριες επιθυμούν την επέκταση του ρόλου τους στην δημόσια, πολιτική και επαγγελματική σφαίρα καθώς και την επέκταση του ανδρικού ρόλου στην οικογενειακή σφαίρα. Επιπλέον, ότι τα αγόρια, παρόλο που διατηρούν παραδοσιακές αντιλήψεις, σχετικά με την ισότητα των δύο φύλων, ωστόσο παρουσίασαν μετά την παρέμβαση μία πιο κριτική και προοδευτική στάση. Συμπερασματικά, η συγκεκριμένη έρευνα αποδεικνύει την ανάγκη εφαρμογής πιο συστηματικής και μεγαλύτερης διάρκειας παρέμβασης στο μάθημα της Λογοτεχνίας.
description: Aim of the specific study is to explore the changes of secondary male and female students’ attitudes towards the promotion of gender equality at school. These changes were monitored after the didactic intervention at the course of literature. The particular intervention focused on the promotion of women’s experience and in particular on the ethic of care through action research. The intervention showed that female pupils are willing to expand their own role at the public, political and professional sphere and that they furthermore desire the expansion of men’s role at the domestic sphere. Additionally, although male pupils hold more traditional values, in reference to gender equality, the intervention had as a result the development of their critical and progressive attitude. Overall, the specific study indicated the need of a more systematic and longer intervention.

Subjects: subject: Transportation Engineering

description: Shrinkage Compensating Concrete (Class S) is made with an expansive cement in which the expansion, if restrained, induces compressive stresses that approximately offset tensile stresses induced during drying shrinkage, thereby eliminating or significantly reducing the occurrence of shrinkage cracking in concrete. The objectives of this study were to evaluate the construction and performance of the Shrinkage Compensating Concrete (Class S) and to compare these characteristics to previous Class S concrete data and to conventional Class AA bridge deck concrete. This report summarizes the construction activities and interim performance of experimental decks and barrier walls constructed of shrinkage compensating concrete.
