Theoretical Charge density Proof of N–N weak bonds of RDX Energetic Molecule
Authors: A David Stephen , M Shankar
Published: May 2020

The bond topological analysis of Cyclotrimethylene-trinitramine (RDX) energetic molecule has been carried out for the wave function obtained from the ab initio and DFT methods of quantum chemical calculations. The geometrical parameters of all bonds are compared with that of experimental reports. The inclusion of diffuse function in HF basis set levels makes the significant shift of bond critical point towards carbon atoms of C–N bonds. The heteroatomic bond density character is well understood from unequal C-cp and cp-N distances in all C–N bonds. For all the level of calculations, the maximum bond density was found for all N=O bonds, attributes the maximum potential energy V(r). The N–N bond properties are strongly depends upon the equilibrium bond length which clears from charge concentration in shorter N1–N4 bond and charge depletion found in longer N2–N5 and N3–N6 bonding regions. The bond topological analysis of all bonds in RDX molecule resulted that the N–N bond is the weakest among all the other bonds. The weakness of N2–N5 and N3–N6 bonds than N1–N4 bond of RDX has also been analyzed from energy density calculation from various level of theories as an alternate for Laplacian of electron density. From the analysis of CHELPG charges at the MP2 level, the N–N bonds of RDX appears to have a significant ionic nature which attributes strong hyperconjugation effect. The hyperconjugation effect of RDX, due to polarization of    N–N bonds, is the additional proof of weak N–N bonds in RDX explosive. The isosurface electrostatic potential shows the electro positive and negative region in the molecule. A large negative potential found at the vicinity of oxygen atoms.
Compliance to Compassion: A pedagogy using emotional engagement and other techniques for teaching accessible design to architecture students.
Authors: Singh Raja
Published: May 2020

Universal Accessible Design in some form is included in the curriculum of all Architecture colleges. This subject is of importance not only from the point of view of compliance, but also for actually providing for the interaction of the Persons with Disabilities with the built environment. A special elective course was framed for architecture students on this subject called ‘Universally Accessible Design’ in an architecture college. The focus of the elective was to create a shift in the minds of the students by emotionally charged pedagogical exercises. The basis of these exercises was the premise that students will make a conscious effort to include Universal Accessibility interventions into the design if they meet and are sensitised towards the experiences of the Persons with disabilities. Along with this, students were made to undergo simulation exercises by themselves using wheelchairs and walking sticks. This was accompanied by case studies and lectures by a disability practitioner. At the end, students were asked to provide a feedback in the form of an anonymous and optional survey. All students agreed to the importance of such special electives for learning Universally Accessible Design. 87.5% stated that the elective has sensitised them towards the people with Disabilities.

Authors: Лапшинов А.Е. , Борисов А.В.
Published: May 2020

Вследствие высокой прочности и устойчивости к коррозии композитная полимерная арматура является хорошей альтернативой стальной арматуре, особенно в условиях агрессивных сред. Однако более широкому внедрению данного вида арматуры препятствуют традиционный консерватизм инженеров - проектировщиков, а также недостаточность экспериментальных данных. В данной статье рассматриваются вопросы нормативно-технического обеспечения и безопасности применения стеклокомпозитной арматуры в бетонных конструкциях. Были изготовлены и испытаны на изгиб 8 бетонных балок длиной 3,2 м, армированных стеклокомпозитной арматурой. Полученные экспериментальные результаты были сопоставлены с результатами расчета по современным нормам проектирования конструкций с композитной арматурой (СП 295.1325800.2017).

Authors: M. Dr. Duraipandian
Published: May 2020

The scaling and as well as the wavelet-functions of the wavelet is detected engaging the wavelet-filters that are empowered with the filter-bank principle that is utilized in recognizing the rough calculation and the feature co-efficient of the wavelet-filter. The coefficients recognized by the filter-bank for the musical sounds produced by the musical-instruments enables one to have a signature-wavelet of the sound signal. The signature-wavelet renovates the actual musical signal with insignificant disturbance. In order to recognize the factors (coefficients) the paper employs the least mean square (L-MS), normalized least means square (NL-MS), recursive least square (R-LS) and the QR-Recursive least square (QR-RLS). Among the above four the R-LS and the QR-RLS performs well under all grounds. More over the algorithm converges swiftly compared to the other algorithm. Thus providing an accuracy and SOC (speed of convergence) improved scaling and wavelet-function recognition.

Production and multiplication of national potato varieties in family farming systems
Authors: P. González P. L. Colnago; F. Vilaró;
Published: May 2020

Potato is the main vegetable in terms of production volume at national level. In Uruguay, two agricultural cycles are carried out every year, in autumn and in spring. Potato small-scale family farmers represent 80% in number and cover only 10% of national area. The current system of seed multiplication allows for two  crops in two years, involving the conservation of seed tubers for six  months. An alternative scheme for family farmers has been proposed, based on the use of national short dormancy varieties. With proper management, it is possible to obtain four crops in two years. In order to support the insertion of family farmers in a multiplication scheme of national varieties and to identify the main management factors to be improved, the monitoring of seed production was carried out in 2016. Farms were visited every 15 days to assess crop growth and health and support decision making. Total yield was estimated and classified into categories. Critical management factors discussed with farmers were crop design and density, emergence, harvest and post harvest management. We found harvest date is a bottleneck for family farmers, where delays in harvest are frequent. The delay of the spring harvest would not allow using these seeds for the autumn crop since they would not reach an adequate sprouting state. In spite of the fact that national varieties have short dormancy, for this scheme of seed multiplication, the spring harvest date is a key factor to ensure a proper sprout status for the next planting season.

Grasping the Social Dimensions of Event Experiences: Introducing the Event Social Interaction Scale (ESIS)
Authors: Marques Lénia , Borba Carla , Michael Janna
Published: May 2020

Experience has been widely recognized as an essential part of an event's success, but few studies have analyzed the processes underlying the event as social experience. This article contributes to a better understanding of the social processes that make an event a social interaction
platform. The social interaction processes that shape the event's social experience is examined using a framework that brings together cocreation practices, group socialization, and interaction ritual chains. This exploratory study investigates the social interaction processes that shape the
event's social experience by developing a quantitative tool, the Event Social Interaction Scale (ESIS), which measures different social dimensions of the event experience. The ESIS was applied at a popular culture event, the festivities of São João in Northeast Brazil, and 625
survey responses were collected in 2016 and 2017. Findings suggest that multiple interaction rituals occur. People who are more directly and actively engaged in the event are more likely to be open for contact with unknown others. The event becomes a multidimensional platform where different
types of social interaction are not only possible but fostered. The ESIS contributes to charting the footprint of the event as social experience, revealing a similar experience footprint across different years of the study. The ESIS and the implications of its processes for the event can be
useful for academics, practitioners, and policymakers interested in understanding and facilitating more engaging event social experiences.

Published: May 2020

One of the most important indicators in the epidemiological studies
of a particular population are the health stats for children and adolescents. The impact that environmental and behavioral factors on a single health characteristic is studied globally. However, there is a deficit
of research studying comprehensive methods to health assessment.
Therefore, the aim of our study is to develop just such a method of
assessing health comprehensively. The psycho-physiological health
characteristics of adolescents residing in the city of Kyiv and aged
12–15 years (n = 98), whose parents gave an informed consent for
this study, have been studied. The construction of the comprehensive health index is based on a grouping of objective and subjective
characteristics of health. We took into account blood pressure, pulse,
body mass index, hand strength, hemoglobin oxygen saturation level
and the level of well-being, normalizing them in the range from 0 to
1 and obtaining an integral estimate, as the average of all the components. In quantitative form, the indicator has a normal distribution
and can be used as a variant in parametric statistical calculations. For
non-parametric statistical methods, health index is proposed to be
normalized on the interquartile range. Such a comprehensive health
indicator can be the basis, upon which epidemiological studies are
founded and to determine the preventive measures at different levels
from individuals to populations.
Keywords: adolescent health, comprehensive health indicator, health
assessment methodology, direct and indirect health indicators, epidemiological studies.

RATIONALE FOR IMPROVEMENT MEASURING INFORMATION ACCUMULATION SYSTEMS DURING THE TESTS
Authors: Andrushko M. , Shein I.
Published: May 2020

With the development and complication of aviation objects, there is reduces the amount of free spaces required to place onboard measurement equipment. In this regard, it is important to choose the minimum dimensions of the test equipment when choosing an on-board measurement system.

The process of creating fundamentally new systems for measuring and processing information during conducting flight tests is not always appropriate, labour-consuming and associated with taking considerable time. One of the traditional line of research on the improvement of economically sound using of technical means of information support of flight tests is the solution of the problem of more complete and qualitative using of the on-board measurement system for conducting tests of production (upgraded) aircraft.

Various forms of functioning and interaction of test object systems, large flows of measurement information, using of a fairly sophisticated mathematical apparatus for its processing and analysis create the need for widespread use of registration and processing facilities based on the modern data carriers and PC to ensure the testing of modern AME in due time.

On-board measurement results are the universal basis for further evaluation of research objects during conducting their tests. Modern live monitoring and recording systems of aircraft have the ability to accumulate a whole data file obtained during a certain operation cycle of different types of aircraft. In the foreseeable future, with a proper adaptation of the database software, the live monitoring and recording systems can be recommended for testing a wide range of aircraft that being upgraded. Database completeness is a problem that needs to be solved during the revamping of information technologies. In drawing up of database, it’s important not to make mistakes when selecting and processing key data, selecting methods of database creation, monitoring and control of the process of database operation. Modern technologies allow to collect large data volume by on-board facilities. It can be resulted in the potential options for using this information not only for operating of production aircraft, but also for testing of upgraded aircraft.

Background:

A quality improvement project at a small midwestern community hospital assessed current education for adult patients with type 2 diabetes and nurses' knowledge and confidence in providing diabetes education.

Method:

The intervention targeted staff nurses on a medical-surgical floor and included a revised diabetes toolkit, development of an education process for patients with diabetes, and multimodality delivery of education about diabetes care.

Results:

Evaluation of the intervention was accomplished through a pre- and postsurvey measuring nurses' confidence. Nurses' confidence improved postintervention (
S
= 26,
p
= .04).

Conclusion:

The project outcome aligned with similar diabetes education projects in the literature that reflected an increase in nurse confidence following an educational intervention. Leadership support of ongoing educational experiences for nurses is necessary to address gaps in knowledge and changes in clinical standards. Patient outcomes may be positively affected if nurses are confident teaching patients how to effectively manage their diabetes.

Business-IT Alignment (BITA) remains a challenging endeavour for many organisations despite the continuous attention it garnered among researchers and practitioners. The literature provides a list of factors determining whether organisations succeed to achieve BITA or not. However, BITA studies were conducted in a few industries in developed countries. This case study is aimed at addressing the lack of BITA studies in developing countries. The data was collected from a bank in Ethiopia through interviews and internal documents. The study employed thematic analysis, which revealed 21 intra-organisational barriers to BITA. Business and IT leaders may find the result of the study invaluable to plan activities that might overcome these barriers and improve BITA maturity, which in turn improves overall organisational performance.
On the Enabling of Efficient Coexistence of LTE With WiFi
Authors: Hassan Mohamed S. , Ismail Mahmoud H. , El Tarhuni Mohamed , Aseeri Fatema
Published: May 2020

The recently proposed extension of the LTE operation to the unlicensed spectrum, known as LTE-Unlicensed (LTE-U), is not only expected to alleviate the congestion in the licensed band but is expected to result in an increase in the network capacity, as well. Unfortunately, such extension is challenged by a coexistence problem with wireless technologies operating in the unlicensed spectrum, especially Wi-Fi. Therefore, this article employs time series forecasting methods to enable efficient LTE coexistence with Wi-Fi. This is done by enabling the LTE-U Home eNodeB (HeNB) to avoid collisions with Wi-Fi by predicting the state of the unlicensed channels prior to using them. Specifically, this research proposes a recurrent neural network-based algorithm that utilizes Long Short Term Memory (LSTM) networks with time series decomposition to predict the state of the channels in the unlicensed spectrum. The authors investigate the performance of the proposed approach using extensive simulations. The results show that the proposed LSTM-based method outperforms the classical Listen Before Talk (LBT) and duty-cycling approaches in terms of improved coexistence of LTE-U with Wi-Fi.

Authors: Singh Neetu , Varshney Upkar
Published: May 2020

Reminders are a very promising intervention for improving medication adherence in mobile health environment. From the published literature, this research find that effectiveness of reminders varies widely and side effects of reminders have not been studied. To address these, this article develops an analytical model to evaluate different types of reminders for medication adherence. The model is also used to estimate side effects of the reminders. The results indicate that context-aware reminders perform better than simple reminders in improving medication adherence for willing patients in mobile health environment. Simple and persistent reminders also lead to more side effects than context-aware reminders. The results of this study will be useful for patients, healthcare providers, researchers and policy makers in improved decision making for medication adherence. The future work can include development of smart reminders to meet different requirements of patients, healthcare professionals and payers in terms of personalization, performance, long-term effectiveness, reliability, and health outcomes.

Published: May 2020

In this article, numerical investigation is carried out for the unsteady MHD mixed convection flow of radiating and chemically reacting fluid past an impulsively started oscillating vertical plate with variable temperature and constant mass diffusion. The transport model employed includes the Hall current. A uniform magnetic field is applied transversely to the direction of the fluid flow. The flow consideration is subject to small magnetic Reynolds number. The Rosseland approximation is used to describe the radiation heat flux in the energy equation. The dimensionless governing system of partial differential equations of the flow has been solved numerically by employing the FEM. The influence of pertinent parameters on primary velocity, secondary velocity, temperature and concentration are presented graphically whereas primary skin friction, secondary skin friction, Nusselt number and Sherwood number are presented in tabular form. The findings of the present study are in good agreement with the earlier reported studies.
COVID-19: Hemoglobin, Iron, and Hypoxia beyond Inflammation. A Narrative Review
Authors: Cavezzi Attilio , Troiani Emidio , Corrao Salvatore
Published: May 2020

Coronavirus disease-19 (COVID-19) has been regarded as an infective-inflammatory disease, which affects mainly lungs. More recently, a multi-organ involvement has been highlighted, with different pathways of injury. A hemoglobinopathy, hypoxia and cell iron overload might have a possible additional role. Scientific literature has pointed out two potential pathophysiological mechanisms: i) severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) interaction with hemoglobin molecule, through CD147, CD26 and other receptors located on erythrocyte and/or blood cell precursors; ii) hepcidin-mimetic action of a viral spike protein, inducing ferroportin blockage. In this translational medicine-based narrative review, the following pathologic metabolic pathways, deriving from hemoglobin denaturation and iron metabolism dysregulation, are highlighted: i) decrease of functioning hemoglobin quote; ii) iron overload in cell/tissue (hyperferritinemia); iii) release of free toxic circulating heme; iv) hypoxemia and systemic hypoxia; v) reduction of nitric oxide; vi) coagulation activation; vii) ferroptosis with oxidative stress and lipoperoxidation; viii) mitochondrial degeneration and apoptosis. A few clinical syndromes may follow, such as pulmonary edema based on arterial vasoconstriction and altered alveolo-capillary barrier, sideroblastic-like anemia, endotheliitis, vasospastic acrosyndrome, and arterio- venous thromboembolism. We speculated that in COVID-19, beyond the classical pulmonary immune-inflammation view, the occurrence of an oxygen-deprived blood disease, with iron metabolism dysregulation, should be taken in consideration. A more comprehensive diagnostic/therapeutic approach to COVID-19 is proposed, including potential adjuvant interventions aimed at improving hemoglobin dysfunction, iron over-deposit and generalized hypoxic state.
A Novel Random Split Point Procedure Using Extremely Randomized (Extra) Trees Ensemble Method for Human Activity Recognition
Authors: Padmaja B , Prasa V V Rama , Sunitha K V N
Published: May 2020

INTRODUCTION: Automatic detection and recognition of various human physical movements while performing daily life activities such as walking, jogging, running, sitting, standing etc. are usually considered as Activity Recognition (AR). AR is a prominent research area in many applications, such as elderly care, security and surveillance, smart homes, health and fitness. Extremely Randomized Trees Classifier (ET Classifier) is a type of ensemble learning technique used in Activity Recognition, which clusters several different decision trees into a forest from a single learning set and gives the classification result. But it suffers from high variance and over-fitting problem due to high inter-dependency among hyperparameters during model building.OBJECTIVES: The primary objective of this paper is to propose a novel RandomSplitPoint procedure for Extra tree classifier to make the existing approach more robust, less variance, less computational time in obtaining optimal split points and faster in model building. This approach generates K random split points from all the candidate features of the dataset and selects the best split point based on the maximum score obtained by information gain measure.METHODS: In the proposed method to improve the randomization and accuracy of AR system, a novel random split-point procedure for ET classifier is proposed. This approach reduces the bias-variance problem induced due to the three hyperparameters such as K, nmin and M used in split-point procedure of existing ET classifier (K : number of randomly selected attributes at each node, nmin : minimum sample size for splitting a node, M : number of decision trees for ensemble). This approach generates K random split points from all the candidate features of the dataset and selects the best split point based on the maximum score obtained by information gain measure.RESULTS: The proposed approach is experimented with two public AR datasets HAR and HAPT (UCI Machine Learning Repository) containing 6 and 12 activities respectively. In HAR dataset, smartphone sensed sensor signals of 3 static and 3 dynamic human daily activities are there, where as in HAPT dataset apart from these 6 daily activities, 6 postural transitions data is available. Experimental results and comparative analysis show that the proposed method outperforms over other existing techniques with an accuracy of 94.16% for HAR dataset and 92.63% for HAPT dataset. It also takes less computational time in finding optimal split-points and less model building time.CONCLUSION: AR systems can be used as an intelligent system in healthcare to monitor the behaviour of healthy people by recognizing their daily activities. These systems also help in early detection of some chronic diseases and improve the quality of life. In this paper, an attempt is made to improve the accuracy of Activity Recognition over some existing methods.

Museum education in semi-peripheries: social, cultural and economic aspects of the globalisation of Polish and Slovak heritage institutions
Authors: Porczyński Dominik , Vargová Lenka
Published: May 2020

The paper examines the problem of change in Central-Eastern European museum education in the globalising world. The main objective is to answer the question of whether museums located in peripheral regions of semi-peripheral states introduce patterns developed in global core-states or maintain the approach invented during the former political period. Its main assumption is that globalisation is a discursive process engaging global, national and local cultural elements, leading to reshaping of local patterns.
The paper is based on 14 in-depth interviews conducted with curators working at local museums of the Subcarpathian and Košice regions, supported by four interviews carried out with museum workers of national museums in Warsaw and Bratislava.

Published: May 2020

Kecepatan angin dan desain sudu mempengaruhi besarnya kecepatan putaran generator, sehingga data kecepatan putar sudu dan kecepatan putar generator menjadi salah satu acuan untuk berbagai keperluan seperti mendesain sudu turbin, data pembanding dengan output generator dalam menentukan kinerja generator dan sistem keamanan turbin. Tujuan dari penelitian ini adalah merancang alat pengukur kecepatan putar (rpm) generator yang dihasillkan dari pergerakan turbin angin. Prinsip kerja dari alat ini yaitu menembakkan cahaya infra merah pada bidang reflektif yang akan memantulkan cahaya inframerah yang kemudian diterima oleh detektor. Alat pengukur kecepatan putar ini menggunakan sensor led inframerah yang dapat memancarkan cahaya inframerah yang tidak kasat mata. Cahaya inframerah merupakan gelombang cahaya yang berada pada spektrum cahaya tak kasat mata yang ditembakkan ke daerah reflektif kemudian ditangkap oleh phototransistor sebagai receiver. Output receiver akan dikonversi dalam bentuk kecepatan putar (rpm) oleh mikrokontroler. Nilai rpm akan ditampilkan melalui display lcd. Berdasarkan hasil pengujian alat diperoleh bahwa error pengukuran paling kecil pada kecepatan 6000 RPM dengan prosentase error sebesar 0.00 %, sedangkan prosentase error terbesar pada kecepatan 500 RPM sebesar 0.04 %. Dari data hasil pengujian yang telah dilakukan , hasil pengukuran masih dalam batas toleransi yaitu sebesar ±10%.

Konsep pembuatan rancangan sistem otomatisasi pada stopbar light ini adalah untuk mempermudah dan membantu pekerjaan ATC dalam melaksanakan pengawasan dan meningkatkan keselamatan penerbangan. Saat ini di bandara Juanda mempunyai suatu masalah yang berhubungan dengan runway incursion, yaitu baik manusia,mobil,alat berat bahkan hewan sekalipun dilarang melewati daerah tersebut,yaitu pada daerah taxiway N3. Karena telah terdapat dalam Notam bahwa hanya pesawat yang telah landing saja yang diperbolehkan melewati daerah tersebut. Pada beberapa saat lalu hampir terjadi accident yang terjadi akibat pilot yang salah dalam pengambilan keputsan,antara tower dan pilot sebenarnya tidak ada pihak yang salah dalam melakukan komunikasi sampai read back pun benar. Hanya saja dalam melakukan implementation pilot mengalami kesalahan. Diharapkan dengan kejadian tersebut alat ini dapat membantu sebagai barikade saat pilot dan ATC mengalami kesalahan.
RANCANG BANGUN MONITORING KETINGGIAN AIR DANAU DAN KONTROL POMPA AIR MENGGUNAKAN MODUL ARDUINO DI BANDARA INTERNASIONAL JUANDA SURABAYA
Authors: Hartono Hartono
Published: May 2020

Pada musim penghujan, di Bandara Internasional Juanda dapat terjadi meluapnya danau dan telatnya pompa untuk membuang air ke sungai yang mengakibatkan air sungai juga ikut meluap. Untuk mengatasi hal tersebut, seorang teknisi harus menuju ke lokasi untuk melihat level danau dan mengoperasikan pompa. Pengoperasian pompa oleh teknisi tersebut dipandang kurang efisien karena belum adanya kontrol otomatis dan sistem Human Machine Interface pada PC. Jarak ruang teknisi ke Pump House yang terletak di dekat danau pun juga cukup jauh yaitu sekitar 2 km. Untuk mengatasi hal tersebut, penulis bermaksud untuk merancang sebuah alat kontrol pompa air otomatis dan monitoring level air danau dan sungai serta kondisi pompa dengan menggunakan modul arduino. Untuk mengetahui level air dan kontrol pompa yaitu dengan menggunakan sensor ultrasonic HC-SR04. Dengan sensor ultrasonic HC-SR04 maka bisa menentukan berapa ketinggian air dan berapa pompa yang harus menyala. Sedangkan untuk mengetahui berapa arus dari masing-masing pompa yaitu dengan menggunakan sensor arus ACS-712. Setelah diketahui level air dan arus dari masing-masing pompa, hasilnya akan ditampilkan pada PC dengan menggunakan Visual Basic sebagai Human Main Interface.
MONITORING DAN KONTROL PADA UPS MENGGUNAKAN MONITORING HUMAN MACHINE INTERFACE ( HMI ) SEBAGAI MEDIA PEMBELAJARAN DI LABOLATORIUM LISTRIK POLITEKNIK PENERBANGAN SURABAYA

Published: May 2020

Gedung Labolatorium Praktik Integrasi di Politaknik Penerbangan Surabaya, belum memiliki alat peraga ( Praktikum ) Uninterruptible Power Supply(UPS), sebagai supply catu daya cadangan apabila PLN OFF. Generator set (genset) membutuhkan waktu sekitar 12 detik untuk menyala setelah PLN OFF, oleh karena itu dibutuhkan adanya UPS guna memberikan perlindungan listrik bersih tak terputus atau interupt pada beban yang terhubung. Jadi, sistem kerja dari UPS tidak pernah OFF dan selalu standby dengan berbagai situasi dan kondisi. Dengan demikian, sistem di dalam UPS semakin lama semakin berkurang ketahanan dan usianya. Ketahanan dalam penyimpanan catu daya cadangan akan semakin melemah karena penggunaan yang setiap saat. Oleh karena itu apabila terjadi gangguan pada salah satu UPS yang dapat menyebabkan UPS tersebut tidak dapat bekerja sebagai mana mestinya, dibutuhkannya backup lain yang tetap akan dapat mem-backup beban UPS yang tidak dapat bekerja tersebut. Peneliti mencoba untuk membuat monitoring dan kontrol pada UPS menggunakan monitoring Human Machine intervase ( HMI ) yang bertujuan untuk menjaga suatu sistem tetap berfungsi dengan normal walaupun terdapat elemen yang tidak berfungsi. Hal ini biasanya dicapai dengan memiliki komponen backup yang berfungsi sama dengan elemen sistem. Sistem HMI pada UPS menekankan pada parameter seperti arus dan tegangan menggunakan personal computer (PC) sebagai interface dengan device pengontrol yaitu Mikrocontroller.

Beberapa kasus pada analisa rangkaian listrik banyak digunakan model matematika dalam menyelesaikannya. Model matematika selanjutnya dirumuskan secara numerik dalam Sistem Persamaan Linier (SPL). Persamaan linier yang dihasilkan dapat diselesaikan dengan menggunakan Metode Numerik yaitu Metode Pembalikan Matriks (matriks invers), metode Cramer, Metode Eliminasi Gauss, Metode Eliminasi Gauss-Jordan dan Metode Dekomposisi LU. Untuk menghitung persamaan dengan jumlah n variable yang tidak diketahui dari sistem yang besar dan kompleks, membutuhkan waktu yang cukup lama dan tidak efisien. Untuk memudahkan dalam perhitungan digunakan aplikasi Bahasa Pemrograman Scilab. Scilab merupakan sebuah freeware yang dapat digunakan secara gratis untuk keperluan pribadi maupun komersial yang tersedia dalam berbagai macam sistem operasi, seperti Windows, Linux, dan MacOS X.
Towards a Better Understanding of a Continuum of Heritage Language Proficiency: The Case of Adolescent Russian Heritage Speakers

Published: May 2020

The study presented here has three goals: (1) to identify types of errors in the noun inflectional
morphology in Russian as a heritage language among Russian-speaking adolescents in Israel
(n=11), the United States (n=11), Finland (n=14), and Germany (n=9), (2) to compare errors in
speech production between these groups, and (3) to investigate the impact of Russian language use
at home and in educational settings (formal bilingual education versus after-school classes) on the
preservation of Russian noun morphology. The participants’ speech was elicited through retelling
of Mayer and Mayer’s (1978) picture book 'Frog, Where Are You?' Case and gender errorsin speech
production were analyzed qualitatively and quantitatively. The groups were found to be clustered
at the opposite ends of a proposed continuum of noun morphology knowledge, with Russian
German and Russian Finish bilinguals outperforming their counterparts in Israel and the U.S. The
results of the study indicate the advantage of predominantly Russian use at home and formal
bilingual schooling for the acquisition of Russian morphology.
