Chinese Dialect Recognition Using X-vector with Multi-task Learning

Speech recognition is often hard for language in countries with diverse accents, like Mandarin. However, the recognition of different dialects may help to improve the later speech recognition. In this paper, we conduct some experiments on a ten-dialect recognition task. We improve the system with different methods, like x-vector and multi-task learning with phone recognition. Finally, with the combination of the methods, we improve the accuracy of baseline model from 76.48% to 88.25%, where the relative improvement is 15%.
Feature Detection in Hierarchical Structure Based on Tensor Factorization

Feature is an important connection point of hierarchical structure. Large-scale network feature detection becomes an important way to analyse hierarchical structure. In this paper, we use tensor decomposition based large-scale network feature detection to study hidden relationships among different users and infer its potential feature structure. Data set experiment is used to verify the effectiveness of the algorithm from two aspects of accuracy and efficiency. At the same time, the two algorithms of tensor decomposition and Fast Newman and SLPA are compared to find that the hierarchical structure feature detection algorithm based on tensor decomposition is more efficient and more accurate.
CONCENTRATED ACID CONVERSION OF PINE SAWDUST TO SUGARS. PART II: HIGH-TEMPERATURE BATCH REACTOR KINETICS OF PRETREATED PINE SAWDUST

A study of high-temperature, concentrated-acid hydrolysis kinetics was undertaken for pretreated pine utilizing a corotating twin-screw extruder reactor. Five different acid concentrations were prepared ranging from 5 to 30 wt. % acid. These solutions were subjected to high-temperature acid hydrolysis at 110°, 120°, and 130°C using a custom-fabricated zirconium batch reactor. A number of nonlinear and linear regression analyses were undertaken so that the concentration of less resistant cellulose, resistant cellulose, glucose, and decomposition products could be obtained as a function of time, temperature, and acid concentration. Application of the kinetic rate constants obtained from the static batch reactor hydrolysis studies demonstrates that more than 50% of the theoretical glucose available in the pine sawdust can be obtained in roughly 25 minutes and 41% of the theoretical glucose available can be achieved in as little as 3 minutes. Further analysis highlights the importance of the pretreatment technique in achieving significant quantities of theoretical glucose in a short high-temperature reaction time.
Taux de change interne et équilibre du compte courant au Maroc : analyse par la méthode de soutenabilité externe

: The internal exchange rate (IER) corresponds to the ratio of the prices of non-tradable goods and services to those of tradable goods and services, it’s appreciation constitutes a handicap for improving the current balance since the increase of this rate encourages investors to orient themselves more and more towards non-tradable activities, mainly made up of building and public works and services, whose prices and margins are relatively more attractive. This work aims to evaluate the effect of the IER on the current account balance equilibrium for Morocco. More precisely, it consists in calculating the Moroccan IER in order to evaluate, thereafter, the link between this rate and the current account balance equilibrium. The results of the analysis of the relationship between the IER and the current account balance show that the surplus needed to ensure the balance of the current account is higher when economic growth is weak requiring a more significant drop in the IER.
Tungsten Bronze-Type Solid Solutions Ba6−3xSm8+2xTi18O54(x=0.3, 0.5, 0.67, 0.71) with Superstructure

Structural parameters of tungsten bronze-type compounds Ba6−3xSm8+2xTi18O54(x=0.3, 0.5, 0.67, and 0.71) were refined in a space groupPbnmby the Rietveld method using high-resolution synchrotron radiation powder diffraction data. All the specimens crystallized in the orthorhombic system with a superstructure having the doubledcaxis of the reported orthorhombic tungsten bronze-type structure. Unit-cell parameters (in A) area=12.1715(5),b=22.3772(3),c=7.67523(9) forx=0.3,a=12.1568(1),b=22.3253(2),c=7.66301(7) forx=0.5,a=12.1472(1),b=22.2972(2),c=7.65338(6) forx=0.67, anda=12.1452(1),b=22.3029(2),c=7.65007(6) forx=0.71, andZ=2. The use of two wavelengths allowed the determination of cation and vacancy distributions over two pentagonal and five tetragonal tunnels in the structure. In the compounds withx=0.3 and 0.5, pentagonal tunnel sites were fully occupied by Ba, and the remaining Ba partially substituted Sm at two of five tetragonal tunnel sites. No evidence was found for the substitution of Sm for Ba at the pentagonal sites, and thus vacancies were formed at the pentagonal sites forx=0.71. An amplitude of periodic modulation along thecaxis, which caused superstructure, was increased with increasingxin the compositional range examined. A relationship between observed and calculated intensities of superstructure reflections suggests the presence of local lattice distortion, which takes its minimum atx=0.67.
Bleeding Incidence in Patients Administered with Warfarin at Secondary Hospitals in Yogyakarta Province

Warfarin is an oral anticoagulant most-commonly prescribed for prevention and treatment of thromboembolism. It is widely acknowledged that warfarin has both narrow therapeutic index and various drug-food interactions, thus carrying the risk of subtherapeutic or bleeding. Therefore, warfarin is among the priority drugs to be evaluated to improve the quality of care for warfarin use. This study aimed to analyze the indications and dosage as well as the bleeding incidence in warfarin use at secondary hospitals in Yogyakarta. This research employed the retrospective cross-sectional design among outpatients and inpatients who received warfarin for a minimum of three days. Data of patient demographics, indications and doses of warfarin, incidence of bleeding, and other drugs interacting with warfarin were collected from the medical records for two years of research. The bleeding incidence could include conjunctival bleeding, melena, hematemesis, petechiae, purpura, ecchymosis, or hematochezia as was documented in the medical records. The research involved 139 patients with a majority of male patients and age range of >60 years. The three highest indications of warfarin use were CHF (37.41%), CHF-AF (23.74%), and AF (10.79%) with an average dose of 1.83±0.54 mg/day. Despite the administration of low doses of warfarin, four patients (2.90%) experienced bleeding with hematuria as the main clinical manifestation. This study recommends adjusting to a lower warfarin dose, particularly for the elderly who receive a combination with aspirin. In addition to a lower maintenance dose, a lower therapeutic target of INR should be further verified for Indonesian patients who receive warfarin.
Characteristics of reject waters and condensates generated during drying of sewage sludge from selected wastewater treatment plants

AbstractThe aim of the investigation was to evaluate the levels of BOD, chemical oxygen demand, biogen compounds (e.g. ammonium nitrogen, phosphates) and the heavy metals (Zn, Cu, Ni, Cd, and Pb) content in supernatants, and condensates generated during sewage sludge drying and reject waters, compared to the concentrations in raw wastewater from selected WWTP in southern Poland. It was stated that when compared to raw wastewater, other liquids were highly polluted with ammonium nitrogen. Reject waters and condensates were not highly polluted with phosphates in contrast to supernatants. The most abundant heavy metal in all samples was zinc, followed by nickel. Copper and lead concentrations were similar but lower than that of zinc. Cadmium concentration was at a very low level. Considering the potential loads of heavy metals, which may be discharged with condensates and supernatants to the head of WWTP, they can be at the level of maximum 2% of the total load. It indicates that one-time effect of these liq.
Memory response on wave propagation in a micropolar magneto-thermo-viscoelastic half-space

The present analysis reports the Kelvin–Voigt-type magneto-thermo-viscoelastic interactions in a thermally conducting unbounded half-space whose surface is subjected to time-harmonic thermal source in the context of micropolar thermoelasticity, being enlightened by memory-dependent derivative (MDD) in the context of three-phase (3P) lag model. The bounding plane of the half-space is stress-free and is subjected to a prescribed temperature distribution. Employing the Laplace transform and Fourier transforms, analytical results for the distributions of the thermophysical quantities have been derived in the transformed domain. The numerical inversions of the respective transforms have been carried out using a suitable numerical scheme based on Fourier series expansion technique. Numerical computations for the stresses, displacement and temperature within the medium have been carried out and also have been demonstrated graphically. Since, micropolar elasticity allows better results to be obtained for microstructural and singular domains as compared to the classical theory of elasticity, therefore, the investigations outline how the micropolarity, magnetic field and viscoelastic parameters influence the thermophysical quantities of the half-space to determine the microstructural changes within the body. Moreover, significant differences on the thermophysical quantities are revealed due to the influence of memory effect and time-delay also, which helps to determine the past effects to the present.

Influence of Water and Loading Rate on Deformation and Failure Behavior of Shirahama Sandstone

Uniaxial compression tests, Brazilian tests and fracture toughness tests were carried out on dry and wet specimens of Shirahama sandstone at several loading rates. Effects of water in the uniaxial compression tests were as follows: (1) UCS and Young's modulus decreased by 42 % to 47 % and 42 % to 46 %, respectively; (2) Poisson's ratio increased slightly; and, (3) No obvious effects were observed on the critical strains. Effects of loading rate were as follows: (1) UCS and Young's modulus decreased as loading rate decreased; (2) No obvious effects were observed on Poisson's ratio; and, (3) Critical compressive strain and the absolute value of the critical extensile strain decreased as loading rate decreased. It was clarified in the fracture toughness and Brazilian tests that the fracture toughness / indirect tensile strength decreased by 70 % to 80 % / 52 % to 72 %, respectively, and that a positive linear correlation was observed between fracture toughness / indirect tensile strength and logarithm of loading rate, respectively. Mechanisms of the above observations were discussed based on the breakage of interlocking between such mineral particles as quartz and plagioclase. Breakage of cementing by illite was also considered.
Educación, justicia social y multiculturalismo: teoría y práctica en el aula

After almost fifty years from the appearance of the term “multicultural education” in the United States, this research wants to show the current trend in this area, after the review of the most recent literature published in prestigious international journals and editorials. Multicultural education is going to be associated with social justice. It refers refers not only to a critical interrogation of power and privilege, but also to acts that intentionally disrupt or respond to systemic oppression towards no-hegemonic groups. A very clarifying example of implementation in the classroom is included in this paper. This proposal encourages a new kind of teacher that gives a great value to dialogue and students´ participation; offers them opportunities to commit to fighting against discrimination; to linking ethical values with political actions; and to applying ideas of justice, autonomy, and reciprocity. This work concludes emphasizing the need to develop this methodology in education aimed at a social transformation supported by values such as active respect, freedom, equity, and social justice. To summarize education requires a perspective that recognizes human diversity as normal. This is very important, bearing in mind the drastic increase of economic, social, and cultural inequality that tends to provoke feelings of humiliation and disrespect in disadvantaged groups. It is a situation that hinders a peaceful democratic coexistence.

Crosslinked polyurethanes with shape memory properties

A series of shape memory polyurethanes (SMPUs) was prepared from polycaprolactone diol (PCL) 4000, 1,4-butanediol (BDO), dimethylol propionic acid (DMPA), triethylamine, and 4, 4′-diphenylmethane diisocyanate (MDI), to which excess MDI or glycerin were added to obtain crosslinked shape memory polyurethanes. Their mechanical, thermomechanical, thermal and shape memory properties were investigated by using differential scanning calorimetry (DSC), Fourier-transform (FT-IR) spectroscopy, dynamic mechanical analysis (DMA) and tensile testing. The results showed that crosslinked SMPUs have better thermal and thermomechanical properties than those prepared from linear polyurethanes and display good shape memory effects.

An Improved Throughput for Non-Binary Low-Density-Parity-Check Decoder

Low-Density-Parity-Check (LDPC) based error control decoders find wide range of application in both storage and communication systems, because of the merits they possess which include high appropriateness towards parallelization and excellent performance in error correction. Field-Programmable Gate Array (FPGA) has provided a robust platform in terms of parallelism, resource allocation and excellent performing speed for implementing non-binary LDPC decoder architectures. This paper proposes, a high throughput LDPC decoder through the implementation of fully parallel architecture and a reduction in the maximum iteration limit, needed for complete error correction. A Galois field of eight was utilized alongside a non-uniform quantization scheme, resulting in fewer bits per Log Likelihood Ratio (LLR) for the implementation. Verilog Hardware Description Language (HDL) was used in the description of the non-binary error control decoder. The propose decoder attained a throughput of 10Gbps at 400-MHz clock frequency when synthesized on a ZYNQ 7000 Series FPGA.
Vacancy Effects on Electric and Thermoelectric Properties of Zigzag Silicene Nanoribbons

We study the crystal reconstruction in the presence of monovacancies (MVs), divacancies (DVs) and linear vacancies (LVs) in a zigzag silicene nanoribbon (ZSiNR) with transversal symmetry. Their influence on the electric and thermoelectric properties is assessed by the density functional theory combined with the nonequilibrium Green's functions. In particular, we focus on the spin resolved conductance, magnetoresistance and current-voltage curves. A 5-atom-ring is formed in MVs, a 5-8-5 ring structure in DVs, and a 8-4-8-4 ring structure in LVs. The linear conductance becomes strongly spin dependent when the transversal symmetry is broken by vacancies especially if they are located on the ribbon's edges. The giant magnetoresistance can be smeared by asymmetric vacancies. Single spin negative differential resistance may appear in the presence of LVs and asymmetric MVs or DVs. A strong spin Seebeck effect is expected at room temperature in ZSiNRs with LVs.
Investigation of Structural Voltage Stability in Tunisian Distribution Networks Integrating Large-Scale Solar Photovoltaic Power Plant

This research shows a structural voltage stability analysis of a distribution network incorporating large-scale solar photovoltaic power plant. Detailed modeling of the transmission network and photovoltaic systems is presented and a differential-algebraic equations model is developed. The resulting system state and load-flow Jacobian matrix are reorganized according to the type of the bus system in place of the standard injected complex power equations arrangement. The interactions among system buses for loading tests and solar photovoltaic power penetration are structurally scrutinized. Two-bus bifurcations are revealed to be a predecessor to system voltage collapse. The investigation is carried out by using bifurcation diagrams of photovoltaic generation margin, load-flow analysis, short-circuits, photovoltaic farm disconnections and loading conditions. Furthermore, evaluation of voltage stability reveals that the dynamic component of the voltage strongly depends on fault short-circuit capacity of the power system at the bus, where, the solar system is integrated. The overall result, which encompasses the views from the presented transmission network integration studies, is a positive outcome for future grid integration of solar photovoltaic in the Tunisian system. Tunisia’s utilities policies on integration of solar photovoltaic in distribution network is expected to benefit from the results of the presented study. Moreover, given the huge potential and need for solar photovoltaic penetration into the transmission network, the presented comprehensive analysis will be a valuable guide for evaluating and improving the performances of national transmission networks of other countries too.
Modelling of partial capability states and estimation of the level of operational readiness for integrated avionics systems

Maintaining continuity of use is extremely important in the modern world and in particular in the armed forces. Analysis of the system exploitation course allows obtaining information about the time in which the system was in a state of total or partial capability or in a state of inability to use. Based on information about the amount of time spent in a given state, user of the system or device can plan the operation of the device in the context of the future. On the basis of operating data, operational readiness can also be calculated, which information can be found in the article. The fallowing paper presents the possibilities and conditions of forming operating readiness for full and partial capability states of a ZSŁ (Integrated Communications Systems) with its selected components current serviced at AFIT (Air Force Institute of Technology). A probabilistic approach to the analysis of the issues associated with the determination and prediction of reliability and capability of integrated communications systems was discussed, with the use of the theory of operating states and Markov chains. The assumptions to the adopted method of modelling operating states for electronically integrated ZSŁ type communications systems were presented. Conditions for the determination of operational readiness and the possibility of forming it on the basis of an IT system were presented based on the obtained results of analytical studies. The article also presents the test stand for the integrated communication system. Information on capability of individual system components is also included, an example is based on the SK1 communication server. It's presented graph of transitions between it's individual partial capability states. The server can be in five operating states. By modelling individual components of the system in this way, you can estimate how the system will behave during operation. At the end of the article there is information about the actual and estimated operational readiness of the system.
