Including Nonlinguistic Processing Tasks in the Identification of Developmental Language Disorder
Authors: Ebert Kerry Danahy , Pham Giang
Published: August 2019

Purpose

Accurate identification of developmental language disorder (DLD) remains challenging, particularly for children who speak different dialects, languages, or more than 1 language. Children with DLD, on average, have shown subtle deficits on nonlinguistic cognitive processing tasks, and performance on such tasks may be minimally influenced by language experience. This study explores whether nonlinguistic cognitive processing tasks can contribute to the identification of DLD in children from diverse linguistic backgrounds.

Method

Study 1 combined data from 4 U.S.-based investigations to yield a sample of 395 children, ages 6–10 years, who spoke only English or both Spanish and English. Study 2 consisted of an international sample of 55 kindergarten children living in Vietnam. Each study included children with DLD and children with typical development. Participants completed nonlinguistic cognitive tasks of processing speed, auditory working memory, and attentional control. Data analysis compared typically developing to DLD groups by age and language background. Then, we empirically derived cut-points to report diagnostic accuracy (sensitivity, specificity, and positive and negative likelihood ratios).

Results

For all 3 tasks, adequate sensitivity or specificity (but not both in most cases) was achieved in nearly all age groups. Likelihood ratios reached moderately to very informative levels in several instances. Diagnostic results were maintained when monolingual and bilingual samples were combined into a single group.

Conclusions

Nonlinguistic cognitive processing tasks may contribute to accurate identification of DLD in combination with other measures. Further research is needed to refine tasks, confirm cut-points established here, and extend findings to children from additional language backgrounds.
Evidence-Based Interventions for Learners Who Are Deaf and/or Multilingual: A Systematic Quality Review
Authors: Crowe Kathryn , Guiberson Mark
Published: August 2019

Purpose

Many educators and speech-language pathologists have difficulty providing effective interventions to the growing population of d/Deaf and hard-of-hearing (DHH) learners who use more than 1 language. The purpose of this review article was to identify evidence-based interventions for speech, language, and literacy used with DHH multilingual learners (DMLs), monolingual DHH learners, and hearing bilingual learners without hearing loss. Interventions used with these groups can inform the practice of professionals providing services to DMLs.

Method

This review article considered speech, language, and literacy interventions used with DHH and hearing bilingual learners from birth to 21 years of age. The following electronic databases were searched: Academic Search Complete/EBSCO (CINAHL, Education, ERIC), Linguistics & Language Behavior Abstracts, PsycINFO, and PubMed. Data describing article, participant, methodological, and intervention variables were extracted from studies. The methodological quality of studies was examined using the Council for Exceptional Children's (2014) standards for evidence-based practice in special education.

Results

A total of 144 studies were reviewed, describing over 9,370 learners aged 1.8–22.0 years. Two studies investigated DMLs, 76 investigated DHH learners, and 67 investigated hearing bilingual learners. A total of 146 different interventions were examined. Most studies reported positive effects. Only 17 studies met all quality indicators specified by the Council for Exceptional Children (2014): 7 examined DHH learners, and 10 examined hearing bilingual learners. There was insufficient evidence for any intervention to be considered an evidence-based intervention, although 6 could potentially contribute to evidence-based practice.

Conclusions

No evidence-based interventions for DMLs were identified. A small number of interventions examined in high-quality studies of DHH and hearing bilingual learners were identified, which may be appropriate for use with DMLs following further investigation.

Teacher−student framework‐based knowledge transfer with incremental block‐wise retraining
Authors: Bae J.‐H. , Yim J. , Kim J.
Published: August 2019

This Letter proposes a stage‐wise training method that uses block‐wise retraining to transfer the useful knowledge of a pre‐trained deep residual network (ResNet) in a teacher−student framework (TSF). To achieve this, flow‐based hidden information transfer and hierarchically supervised retraining of the information are alternatively implemented from bottom to top between teacher and student ResNets in the TSF. To evaluate the effectiveness of the proposed method, the authors used well‐known image data sets Canadian Institute For Advanced Research (CIFAR)‐10, CIFAR‐100, and street view house number. The results showed that the flow‐based bottom‐up knowledge transfer combined with incremental block‐wise retraining can provide the improved small student ResNet with higher accuracy than the deep teacher ResNet. This approach will help extend the use of deep neural network models to limited computing environments.
Programmable manipulation of zeroth‐order resonance based on an active and digitally coding metamaterial antenna
Authors: He Yiming , Yang Guangli , Luo Yong
Published: August 2019

In this Letter, the authors focus on the programmable manipulation in frequency spectrum through an active Metamaterial (MTM) antenna with digitally coding sequences. The MTM cell operates in the zeroth‐order resonance (ZOR) where the resonances are independent of the physical length, providing the freedom to utilise arbitrary cell number with keeping the resonance. Benefiting from the isolated periodical cells, n‐cell MTM can be tuned by PIN diodes cell by cell individually, hence, achieve many tunable states, which can be coded digitally with sequences, compatible to evolve to programmable functionalities. Micro‐Controller Unit with C Language is utilised to realise programmable voltages for supplying diode switches, resulting in programmable ZOR (PZOR) in one of the 5G band (4.8 to 5.2 GHz), and unfolding the advantages in achieving many NB (Narrow‐Bandwidth) spectrum channels. The proposed programmable MTM ZOR with sliced‐NB channels is suitable for NB‐IoT (Internet of Things) in the near future.
Optimal search algorithm in a big database using interpolation–extrapolation method
Authors: Kabir M.N. , Alginahi Y.M. , Ali J. , Abdel‐Raheem E.
Published: August 2019

Fast data search is an important element of big data in the modern era of internet of things, cloud computing, and social networks. Search using traditional binary‐search algorithm can be accelerated by employing an interpolation search technique when the data is regularly distributed. In this work, the interpolation search is investigated in which the search results provided unexpected sluggish progress during a search in a large database due to the irregular distribution of data. Irregular distribution of data does not allow the interpolation to make a good prediction about the location of the search item. To overcome this issue, an interpolation–extrapolation search (IES) method is proposed where the interpolation method is integrated with an extrapolation method that balances the lower and upper bounds of the search interval. The proposed method provides faster convergence property than the binary search and the interpolation method. Hence, the proposed IES method provides a faster search for items in a big database.

Context. The origin of the observed diversity of planetary system architectures is one of the main topics of exoplanetary research. The detection of a statistically significant sample of planets around young stars allows us to study the early stages of planet formation and evolution, but only a handful are known so far. In this regard a considerable contribution is expected from the NASA TESS satellite, which is now performing a survey of ~85% of the sky to search for short-period transiting planets.

Aims. In its first month of operation TESS found a planet candidate with an orbital period of 8.14 days around a member of the Tuc-Hor young association (~40 Myr), the G6V main component of the binary system DS Tuc. If confirmed, it would be the first transiting planet around a young star suitable for radial velocity and/or atmospheric characterisation. Our aim is to validate the planetary nature of this companion and to measure its orbital and physical parameters.

Methods. We obtained accurate planet parameters by coupling an independent reprocessing of the TESS light curve with improved stellar parameters and the dilution caused by the binary companion; we analysed high-precision archival radial velocities to impose an upper limit of about 0.1 MJup on the planet mass; we finally ruled out the presence of external companions beyond 40 au with adaptive optics images.

Results. We confirm the presence of a young giant (R = 0.50 RJup) planet having a non-negligible possibility to be inflated (theoretical mass ≲ 20 M⊕) around DS Tuc A. We discuss the feasibility of mass determination, Rossiter-McLaughlin analysis, and atmosphere characterisation allowed by the brightness of the star.

Published: August 2019

The purpose of the study is to consider the possibility of using microsilica - waste of aluminum production, as filler in a vacuum insulation panel. The properties of silicon dioxide powder have been studied, and compositions and manufacturing technology of vacuum thermal insulation panels on its base have been developed. Differential thermal analysis of powders is carried out; the curves of differential thermal analysis and thermogravimetric analysis, x-ray phase analysis are obtained. The microstructure of the samples is investigated. The thermal conductivity of the manufactured panels is measured. The test results suggest that for the manufacture of low–vacuum insulation panels of microsilica powders, waste production of crystalline silicon can be used. The use of waste in the future can become the basis for the production of high-quality vacuum insulation with low cost.
Combined processes of environmentally friendly technology for magnetic-pulse welding
Authors: Strizhakov Evgeny , Nescoromniy Stanislav
Published: August 2019

Various techniques for producing fixed joints in solid using electromagnetic fields are considered; basic diagrams, physics, features, and technical capabilities of each method are described. It is shown that thin-walled tubular irregular structures can be obtained under the magnetic-pulse moulding welding that joins the combined actions of induced currents passing through the overlap zone and magnetic pressure for apposing the weldable edges and for shaping in accordance with the matrix configuration. Obtaining joints from dissimilar materials and structures of different thicknesses is implemented due to shock pulse capacitor welding with magnetic pulse drive. The series connection of the weldable parts enables to synchronize the current flow and force impact on the weld junction. Depending on the combination of the weldable products, three techniques of shock pulse capacitor welding with magnetic pulse drive are proposed. To intensify the quality improvement of the female connectors obtained, it is proposed to use the magnetic-pulse welding in vacuum instead of the diffusion welding. Preheating of the complete unit in vacuum allows for the pre-activation of the connectable surfaces. A unique feature of the implemented diagram is a remote action on the telescopic joints of dissimilar alloys heated in vacuum to the pre-melting temperatures through a quartz glass.

Published: August 2019

When modeling temperature fields in details of different geometry on the basis of the obtained calculations, the graphs of temperature dependence on the power of the source and the thickness of the deposited layer, non-contact measurement of temperatures in the working area and the sub-sequent calculation of temperature fields allow describing the thermal processes in the electromagnetic surfacing in the first approximation. The determination of temperatures should be carried out taking into account the accumulation of heat by an infinite cylinder with a constant source evenly distributed over its lateral surface.

Published: August 2019

The topicality of studied subject is based on inappropriate usage of different materials in wooden structures, since using metal joint in wooden construction leads to reduction of construction working life cycle. In this regard, a study of several options for wooden screw carving was conducted in order to determine the most appropriate one (screw). There are several different types of carving, such as: trapezoidal, triangular, rectangular, etc. The most appropriate ones are trapezoidal and triangular-section threads for wooden screws. The effectiveness of a wooden screw thread was determined from the conditions (capacity) of shear fracture and bearing stress. After analyzing the results of calculations of the specific capacity for shear fracture and bearing stress, it can be concluded that the value of specific bearing capacity for shear fracture is less than the value of bearing stress by 1.3%. Therefore, a further comparison of the trapezoidal thread and the triangular cross-section will proceed from the spalling conditions. It has been found that the most effective thread is a triangular cross-section. Based on the results of calculations, a mathematical model has been established that describes the dependence of the carrying capacity on the screw diameter.

Published: August 2019

The paper is dedicated to waste processing management in waste processing technology. Processing of scrap concrete waste, similar in composition and condition to traditional raw materials, is economically and ecologically feasible. Secondary crushed stone obtained by crushing scrap of reinforced concrete panels in demolished five-storey apartment blocks of the first phase was studied. It is shown that concrete with scrap concrete waste shows strength properties similar to primary concrete and helps organize waste-free production. The methods of recycled waste usage, especially usage of secondary crushed stone made of crushed concrete scrap, are becoming ever more relevant with every passing year. Imported concrete aggregate volumes can be reduced by 15-30% due to usage of secondary crushed stone. Consideration of industrial waste problem and methods of solving this problem by using waste in construction industry, including secondary crushed stone made of crushed concrete scrap, is made. Annually, about 11.5 million tons of construction waste is generated in Moscow. The use of industrial waste similar in terms of composition and condition of traditional raw materials unquestionable from economic and environmental point of view. This study showed that concrete using fine granulated blast furnace slag as cement additives has higher initial strength characteristics.

Published: August 2019

The development of prefabricated residential buildings construction is regarded. Organizational and technological features of building construction are disclosed. An approach to determine the period of the construction of buildings, taking into account serviceability is given. This serviceability is expressed in terms of the consolidation of prefabricated elements, using the example of the standard series of residential buildings (KOPE, I-155). The calculation formulas for determining the period of construction of substructure and superstructure are specified. The period depends on the average daily number of erected prefabricated parts. The resultant dependence between the period of the erection of prefabricated elements and the number of erected storeys is substantiated. The proposed optimization methods will reduce energy costs and make the construction process less energy intensive.

Published: August 2019

The paper discusses the relevance of the use of metallurgical wastes crushed to a fine state in the production of building materials. Domain granulated slag (DGS) was used as a research object. A method for introducing fine ground slag (FGS) into the cement composition in the form of a slag suspension instead of mixing water has been developed. To establish the uniform distribution of FGS particles in the cement matrix, the behavior of slag particles in an aqueous dispersion medium was previously studied. The optimal parameters of ultrasonic dispersion of slag suspensions are established: the frequency of ultrasonic vibrations is 44 kHz; temperature of dispersion - 25±2°C; dispersion time - 15 min. It has been established that the application of UST to slag suspensions with the observance of optimal dispersion parameters can increase the aggregative and sedimentation stability of the FGS suspension by 2–3 times as compared with mechanical mixing, accelerate the micelle formation process, and enhance the electrostatic factor of aggregative stability.
Revisiting the analogies of physical processes and connection between thermal and acoustic indexes of roll flooring materials
Authors: Gerasimov Anatoly , Saltykov Ivan
Published: August 2019

This issue shows the close correlation between thermophysical and acoustic properties of roll flooring materials, such as linoleum, rubber linoleum and carpet covering. The thermophysical properties are characterized by the heat absorption index, S, and the main acoustic feature is the index of impact noise insulation improvement, ΔLnw. The analyses of equations for boundary conditions, as the smooth transition of temperature and heat flow through the interface of two media, allowed revealing the mathematical similarity between acoustic and thermal wave transmission processes, in particular, between the thermal and acoustic impedances. This similarity provided the basis for correlation research between the heat absorption specific coefficient and the index of impact noise insulation improvement values. Therefore, the correlation formula for different types of roll flooring materials was obtained.

Authors: Shcherbakov Vladimir , Akulshin Aleksandr , Bachmetev Aleksandr , Akulshin Anatolyi
Published: August 2019

The paper is devoted to the problem of optimal design, construction and operation of water supply systems and their elements. The key element of the system is a water well. The quality of its design and construction determines the operation of the water intake as a whole. Disadvantages in the construction of a well lead to disruption of the entire water supply system of a particular object. The paper proposed a methodology for selecting the optimal diameter and length of the well filter of a water well. Based on the methodology, an example of filter parameters selection for hydrogeological conditions of the city of Kursk is given. The above calculation showed that the use of the entrance velocity criterion in the design of wells can significantly reduce the cost of well construction while ensuring the design flow rate and allowable lowering of the water level. The cost of the filter, depending on the well design, is 20-30% of the total price for its construction. The most important filter parameters affecting the cost of a well are its length and diameter. Justifying the minimum diameter of the filter that ensures the designed water intake and allowable dewatering can significantly reduce the cost of the well, taking into account the fact that modern pumping equipment allows the use of columns of small diameter above the filter.

Digital economy and green economy: rural unemployment and territorial self-development in Russia
Authors: Aleksandrov Igor N. , Fedorova Marina Yu.
Published: August 2019

The unemployment, low quality of life and low salaries are the main problems of the Russian countryside which is in the process of dying now. The out-migration from rural territories to big cities such as Saint- Petersburg and Moscow takes place all other the country. It damages the regional economy due to the outflow of human resources. We assume that the rate of unemployment in rural Russia is higher than statistics data shows, because the majority of unemployed do not want to be registered by state bodies. A survey of countryside local residents showed that they need extra money, they are not familiar with entrepreneurship through the Internet, they are interested in making money through the Internet. Taking in mind the realm of the digitalization and post-industrial economy, we propose to renovate the rural economy with the help of self-development tools that involve the local community in the entrepreneurship in digital economy. That is why we propose to work with locals, teaching them to earn money with the help of Internet.

Published: August 2019

Achieving energy security by preventing and timely eliminating the consequences of accidents at energy facilities and in energy supply systems of enterprises is one of the important tasks of energy management. The basis for planning appropriate energy security measures is the prediction of damage from these accidents. The purpose of forecasting is to assess the possibility of an accident occurring at some point in time and leading to a particular damage, and to assess the magnitude of this damage. The article proposed methodological approaches to the construction of mathematical models of such prediction. In this case, as an indicator of damage, the economic losses caused by these accidents are taken. The simulation is based on the representation of this indicator in the form of a step change function of the magnitude of losses in the event of an accident. Depending on the amount of information available in the period prior to forecasting, the mathematical representation of the forecasting problem is reduced to the construction of conditionally determined or stochastic models. Conditionally determined models allow obtaining acceptable damage estimates with a short period of retrospection and small amounts of information, and stochastic models with significantly large amounts. At the same time, the principle of “maximum uncertainty” formalized in the form of maximum entropy is the basis for removing uncertainty in the construction of both conditionally determined and stochastic models. Its use has allowed increasing the objectivity of forecasts by minimizing the subjective information used in modeling. The proposed approaches to the construction of mathematical models for predicting accidents at energy facilities and power supply systems of enterprises are the basis for creating specific techniques for solving relevant energy management tasks both at the micro level at the scale of individual enterprises and at the macro level at the scale of industries, regions and the state as a whole.

Authors: Zharov Vladimir , Tsukerman Viacheslav
Published: August 2019

For the Arctic municipalities, the actual problem of their sustainable development is the reduction of industrial emissions of pollutants into the environment together with production waste, and a decrease in the amount of already accumulated waste. The aim of the study is to develop a scheme for the provision of state financial support to industrial enterprises for the introduction of technologies that reduce the level of energy and resource capacity of production. A procedure for developing such support has been proposed in the form of a system of priorities and criteria for selecting industrial en-terprises. The criteria for such a selection are formulated. It is pro-posed to use the imitational dynamic model of the enterprise’s inno-vative development, which introduces an analytical relationship be-tween the set target increase in the share of value added in the value of industrial products and the amount of investment in fixed capital necessary to achieve this goal. It is shown that using such a model to develop medium-term forecasts for the development of enterprises, it is possible to calculate the increase in the volume of basic taxes that will receive the budgets of all three levels of the Russian budget sys-tem.

Published: August 2019

The article is about the use of membrane technologies in water treatment cycle for boiler houses which use water of superficial reservoirs for operation. Working process of a flat membrane element is described in the article. Movement scheme of purified water streams is introduced. The layer of undesirable deposits which are slowing down membrane operation is formed on membrane surface during its operation. This formed layer is a result of the arising concentration polarization. Impact of low-frequency fluctuations on saturation water stream is offered to decrease concentration polarization which leads to decline in production of membrane devices. Fluctuations were brought in a stream by means of the vibrator. Steady standing waves are in the membrane device as a result of vibration effect. These waves reduce the formation of undesirable deposits layer on a membrane surface. Results received by mathematical modeling and confirmed by experimental studies state that process productivity of ultrafiltration increased by 30% in frequency range of 60-70 Hz. Frequency range is in standing wave.

Authors: Gnevanov Mikhail , Sharlaimova Anastasya
Published: August 2019

This study examines the impact of organizational commitment on upgrading ERP for maintaining the quality of information and the performance. Many manufacturing companies in East Java have been implementing ERP in managing their business. Although the ERP post- implementation has been continuously maintained by these companies, the inevitable changes and development in the current business practices have forced them to upgrade their ERP infrastructure. All ERP system upgrades require a commitment from both management and employees, which is also known as the organizational commitment. This research used the employees of 110 manufacturing companies in the region of East Java, which have been implementing ERP for more than two years. The response rate is quite good, as many as 90 questionnaires out of 110 distributed questionnaires are completed by the respondents. Data analysis has been performed using partial least square (PLS) technique. The result demonstrated that the organizational commitment brings a significant impact to the ERP infrastructure upgrade. The organization commitment shows a significant impact on the information quality, but does not show a direct impact towards the ERP performance. Similarly, the ERP infrastructure upgrade also shows a significant impact on the information quality, but does not show a direct impact on the ERP performance. The information quality has a positive impact on the ERP performance. In total, the organizational commitment directly and indirectly affects the ERP performance. The management commitment empowers the key user to be aware of the ERP system upgrading all the time. Keeping ERP to the most up-to-date condition will contribute to the high quality of the information. Furtherly, the best information quality provides the appropriate information in term of the right time and the right information in the decision making process. The appropriate information enables the top management to make decisions in the pursuit of improving the company’s performance.

Authors: Reshnyak V.I. , Kazmin K.A.
Published: August 2019

The paper is devoted to the organization of cleaning oily water, which is one of the parties to the problem of environmental protection in case of accidental oil spills. The oily water is formed during the elimination of an accidental spill. The organization of oily water purification is a limiting factor determining the effectiveness of the entire accidental spill response operation. Firstly, the organization of oily water purification is characterized by the effectiveness of the purification devices used. Secondly, it is characterized by the organization itself providing the response to an emergency spill with these devices. It has been stated that the effectiveness of cleaning devices is determined by the technology used in the cleaning device and by its design. Purification technology is determined by the properties of the treated oily water and the purification quality requirements. The technical solution for a cleaning device that can be applied for oil spill response has been proposed. The organizational and layout schemes for providing an oil spill response were developed, which makes it possible to select the most proper scheme considering the conditions for particular spill response.

Unified land use in the modern system of state cadastral registration
Authors: Golyakova Yulia
Published: August 2019

Abstract. This paper discusses the features of such a unique land plot type as the unified land use. This type of a land plot appeared by virtue of the Russian Federal Law No. 28-FZ “On the State Land Cadastre” dated January 2, 2000. However, the current land legislation does not contain such a term. Currently, the unified land use cannot be formed, but previously registered land still exists in the state cadastre. In addition to a number of features in the land register procedure, the unified land use has no restrictions and freely participates in civilian circulation. Land plots that are the unified land use may be subject to all types of transformation specified in 11.9 of the Land Code of the Russian Federation, with the transformation into two types: the so-called ordinary plot and multi-contour land plot. It should also be noted that there is no term of multi-contour land plot in the land legislation. Some authors draw an analogy between the unified land use and a multi-contour land plot. However, there are a number of differences.
Specially protected natural areas of the Russian Far North
Authors: Okmyanskaya Valentina
Published: August 2019

An important measure of the legal protection of the economic and social interests of small groups of indigenous people is the allocation of territories of traditional nature management. When it comes to territories of traditional environmental management of indigenous people as specially protected natural territories, the regime of environmental management should be environmentally reasonable, socially acceptable and cost-effective. However, the realization of these conditions is tough. The task is to direct the process of development of the territories of traditional environmental management in an environmentally safe course, to try to integrate these territories into various spheres of life of indigenous people, especially in the northern regions, until they are roughly integrated exclusively into the production sphere. The difficulties of the legal plan are caused by the inconsistency of the sectoral federal and regional legislation, the protracted procedure for the development of the status, regime and, especially, the territorial boundaries of the territories of traditional environmental management.
