Authors: Meleshko Ye. , Khokh V. , Bosko V.
Published: January 2020

Об’єктом дослідження є процес створення списків рекомендацій відвідувачам веб-сайтів. Метою даної роботи є дослідження існуючих матричних факторизаційних моделей рекомендаційних систем. У рекомендаційних системах факторизація застосовується до матриці рейтингів з метою виявляння прихованих факторів, властивих об’єктам системи, що впливають на вподобання користувачів. Матричні факторизаційні моделі рекомендаційних систем досить популярні серед розробників та мають багато модифікацій. У даній роботі розглянуто наступні моделі: FunkSVD, SVD++, Asymmetric SVD та timeSVD. Факторизаційні моделі рекомендаційних систем використовуються у методах колаборативної фільтрації на рівні з моделями на основі сусідства. На відміну від моделей на основі сусідства, які використовують коефіцієнти подоби для створення списків рекомендацій, дані моделі використовують не подобу, а приховані фактори. Перевагами таких моделей є підвищена, порівняно з іншими моделями, робастність до атак ін’єкцією профілів та висока точність прогнозування вподобань користувачів. До недоліків досліджуваних моделей слід віднести погану масштабованість, довгий час навчання, а також необхідність повного перенавчання системи при появі нових даних, що частково вирішено лише у асиметричному SVD. Проведене дослідження показало, що існуючі моделі матричної факторизації дають можливість використовувати як явні зворотні зв’язки від користувачів (рейтинги об’єктів, виставлені користувачами), так і неявні зворотні зв’язки (перегляди об’єктів, написані коментарі, тощо), що дозволяє підвищувати точність роботи рекомендаційної системи на веб-ресурсах, де користувачі залишають багато неявного зворотного зв’язку. Такий принцип вперше був реалізований у SVD++. Факторизаційні моделі дозволяють також враховувати неперіодичні та періодичні зміни вподобань користувачів у часі, що, зокрема, реалізовано у timeSVD

Сучасні методи екранування допускають використання найбільш придатних металевих матеріалів для одночасного вирішення декількох задач для захисту працюючих та електромагнітної сумісності технічного обладнання. Одним з таких ефективних металевих матеріалів вважають аморфні магнітом’які сплави. Предмет дослідження даної роботи – визначення захисних властивостей аморфного магнітом’якого сплаву при різних значеннях частотних та амплітудних характеристик в залежності від зміни товщини стрічки матеріалу. Досліджено магнітні властивості пермалою від різної частоти екранованого поля з різним відсотковим вмістом нікелю та різною товщиною захисного металевого матеріалу; залежності коефіцієнта екранування магнітом’яких аморфних сплавів від індукції зовнішнього магнітного поля; коефіцієнти екранування аморфного магнітом’якого сплаву різної товщини та різного відсоткового вмісту кобальту від змінних значень амплітуди; магнітооброблений стан та вихідний стан (недоліки та переваги для конкретних умов використання при захисті та економічних вимог); залежності магнітної проникності магнітом’якого аморфного сплаву від різних значень частоти та амплітуди. Мета роботи - визначення коефіцієнтів екранування захисних аморфних магнітом’яких сплавів від амплітудно-частотних характеристик екранованого магнітного поля та обґрунтування ефективності використання таких матеріалів та надання конкретних рекомендацій щодо захисту від електромагнітних полів та випромінювань працюючих людей та сумісності електричного та електронного технічного обладнання. Розроблено захисні властивості магнітних екранів на основі аморфних сплавів у різних амплітудно-частотних діапазонах. Запропоновано раціональні обґрунтовані рекомендації щодо вибору матеріалу для забезпечення найбільш придатних значень коефіцієнтів екранування Доведено експериментально що аморфні магнітом’які сплави мають сприятливі коефіцієнти екранування від частоти екранованого поля, що підвищує ефективність захисту від магнітних полів працюючих людей та спрощує, з економічної точки зору, обрання матеріалу на конкретному виробництві. Отримані графічні залежності надають можливість обирати необхідний захисний металевий матеріал та автоматизувати процеси розроблення засобів оптимального екранування магнітних полів. Багатосерійність досліджень та легка керованість властивостей матеріалів з різним вмістом металевої субстанції, різної товщини стрічки матеріалу, тощо надає змогу змінювати загальні захисті властивості металевого сплаву ( в залежності від поставленої умови на виробництві)
SYNTHESIS OF INVENTORIES TO THE INTERFERENCE OF INFORMATION AND TELECOMMUNICATION SYSTEMS
Authors: Shefer О. , Topikha B. , Shefer V. , Myhal S.
Published: January 2020

The article deals with the development of analytical algorithms of information and telecommunication systems formation that are invariant to the obstacle (additiveornon-aditiveone). The basic approaches to determine the class of obstacles for which an invariant system can be constructed are discussed and analyzed in detail. It is established that the invariance property of a feedback system guarantees the given probability of receiving information, but it does not guarantee a preset speed of information transmission. Studies have shown that invariance is achieved by reducing the noise immunity of additive noise. In a second-order phase-difference modulation system, the error probability is invariant to the signal frequency, but it is greater than the error rate in the system with phase-difference modulation at a constant signal frequency. As a result of the conducted researches it is established that the maximum of the undetected error does not depend on the characteristics of the interference, but is determined solely by the parameters of the correction code. The ways of improving the qualitative characteristics of information and telecommunication systems to ensure their invariance to the obstacle have been determined by analytical means, which is confirmed by simulation results and experimental data

Published: January 2020

En este artículo presentamos la investigación etnográfica realizada sobre uno de los círculos territoriales del partido político Podemos de España, etnografía caracterizada por la multilocalización y fragmentación de su objeto de estudio. Concretamente indagamos en la estructura organizativa y en las significaciones sobre la política que delinean su imaginario, a través de una observación próxima y sensible, de entrevistas y de un análisis documental de los escritos oficiales de Podemos.Finalmente sostenemos que los círculos territoriales representan una novedad en las formas de participación política tradicionales.  Son parte de una forma de organización asamblearia que impulsa la acción política y que no encontramos en otros partidos tradicionales. Sin embargo, no podemos dejar de reconocer que en los últimos años el método participativo y la horizontalidad que caracterizaron a los círculos han empezado a debilitarse.

Quantitative Weld Quality Acceptance Criteria: An Enabler for Structural Lightweighting and Additive Manufacturing
Authors:   American Welding Society, DONG PINGSHA
Published: January 2020

Most of the existing weld quality acceptance criteria stipulated in various codes and standards, as well as in recommended practices, are empirical in nature. Historically, these workmanship-based criterias have been adequate for quality control purposes in construction of welded structures. However, as the competition for achieving structural lightweighting intensifies, more quantitative quality acceptance (also known as fitness-for-purpose based) criteria are increasingly called for. This is because various new forms of discontinuities and joint configurations (e.g., dis-similar materials joints) cannot be readily related to existing acceptance criteria. Even if existing criteria can be made applicable, recent research findings have shown that existing criteria can be excessively conservative for some and unconservative for others when dealing with thin gauge and lightweight construction. A similar situation exists for additively manufactured metallic components, which can be viewed as “all weld metal” components containing randomly distributed discontinuities over the entire component volume. In this paper, some of the recent developments in quantitative weld quality acceptance criteria will be first highlighted, some of which are made possible by advanced fracture mechanics analysis techniques. Applications in structural lightweighting and additive manufacturing will then be demonstrated with some real-world examples. Finally, implications on a broader application of the methodologies presented for ensuring both structural integrity and cost-effectiveness in construction will be discussed in light of these developments.
LOW COST EMBEDDED CONTROLLER SIMULATION FOR MISSILE IN REAL-TIME ENVIRONMENT
Authors: Putro Idris Eko , Septanto Harry
Published: January 2020

This paper focuses on the development of real-time environment for low cost embedded system to control flight performance of missile. Real-time simulation is generated by using xPC target so that standalone target boot can be developed, and target PCs can be simulated in real-time. Two PCs and single board computers (SBCs) are required to configure the host and standalone target respectively. The host PCs are used to control the target PCs while these target PCs run simultaneously in real-time. Target PCs are divided into plant platform and controller platform. Plant platform represents missile dynamics model, while control algorithm is compiled to the other system as controller platform. Linear control synthesis will be implemented for maintaining flight stability of missile using optimal control approach based linear quadratic regulator (LQR). This real-time system should resemble the environment of future flight test.Keywords: r

On the Etymology and Semantic History of Slavic *kras-
Authors: Varbot Zhanna
Published: January 2020

The history of how humans discovered percussion methods of fi re-lighting presupposes the primacy of the meaning ‘cut, hew' for Proto-Slavic *kresati, the ‘fi re striking' semantics of the verb being a more recent development. The article argues for the hypothesis that the noun *krasa, denoting a craf-ted piece perfect in shape = a beautiful object (cf. the motivational pattern of Latin formosus ‘shapely, beautiful'), could be a derivative of *kresati. The ‘fi re making' semantics developed by *kresati would in its turn moti-vate the shift towards the meaning ‘red (color)', by association with fire.

Published: January 2020

ABSTRACT Pakcoy (Brassica rapa L.) is a type of vegetable crop and one of the short-lived species needed by the body because it contains good nutrition. In order to meet the needs of pakcoy, it must also be balanced with the production level. One of the efforts to increase the production of pakcoy is the nutrient application of liquid organic fertilizer (LOF) from jiringa hulls. LOF can be absorbed by plants quickly rather than solid organic fertilizers and it does not damage soil structures such as synthetic chemical fertilizers. This study aimed to determine the optimum concentration of LOF on growth and production of pakcoy. The research took place at the Green House Laboratory of Agronomy, Faculty of Agriculture, University of Bengkulu. This research used Completely Randomized Design (CRD) with one treatment factor and repeated 5 times, each treatment unit included 3 potted plants. Treatment of LOF concentration, consisted of 5 levels: T0: LOF 0% (Control), T1: LOF 25%, T2: LOF 50%, T3: LOF 75%, T4: LOF 100%. The concentration of L0F 100% produce the best growth and production of pakcoy and has longest canopy (22,18 cm), highest number of leaf (15,86 strands), widest leaf width (34,26 cm2), highest fresh canopy weight (68,85 gram), highest total dry weight (6.92 grams), highest greenish leaves (48.48), and highest dried root weight (1.72 grams). Keywords: LOF, Jiringa Hulls, Pakcoy, Concentration
The Growth and Yield of Sweet Corn under Minimum Tillage Technology by Using Various Doses of Herbicide Mixtures of Glyphosate and 2,4-D
Authors: Simanuhuruk Bilman Wilman , Simarmata Marulak , Aprianto Ayyi
Published: January 2020

Glyphosate is a widely used herbicide for minimum tillage technology because it effectively kills broadleaf and grass weeds. Mixing glyphosate with other herbicide that has a different mechanism, such as 2,4-D may increase control efficacy and prevent the evolved of resistant weeds.  Research was conducted to obtain the effective dose of glyphosate and 2,4-D mixtures and to evaluate the effect of the herbicide mixtures on the growth rate and yield of sweet corn. Depression on summed dominance ratios (SDR) and increased number of dominant weeds were observed after the application of glyphosate and 2,4-d mixtures. The interaction of the herbicide mixtures was observed optimum at the doses of glyphosate and 2,4-D of 1.94 and 1.5 L ha-1, respectively, with maximum of net assimilation rates (NAR) at 4-6 weeks after planting of 0.0003617 g cm-2 days-1.  Plant growth rates (PGR) and NAR were observed maximum by a single treatment of glyphosate at a dose of 1.5 L ha-1 which were 2.23614 and 2.23607813 g cm-2 days-1, respectively.  Yield of sweet corn observed as fresh-weight of cobs was found maximum of 129.41 g with a single treatment of glyphosate at 2,018 L ha-1.

No Additional Evidence that Proximity to the July 4th Holiday Affects Affective Polarization
Authors: Brandt Mark John , Turner-Zwinkels Felicity Mary
Published: January 2020

One promising approach for reducing affective polarization is priming a shared American identity and one promising event to prime that identity is the 4th of July. Prior work showed that proximity to the 4th of July reduced affective polarization. We conceptually replicated this study using a 9-wave longitudinal design in 2019. We found no short-term or long-term effects of the 4th of July on social distance from partisan and ideological ingroups or outgroups. Notably, our within-subjects design was able to identify the existence of individual differences in social distance trajectories across time, but there were not individual differences in short-terms changes in social distance in close proximity to the 4th of July. Additional analyses, did not find consistent predictors of these individual differences, suggesting a clear gap for future studies. Although priming a shared American identity may be effective, these findings suggest that the salutary effects of the 4th of July holiday do not emerge in 2019.

Published: January 2020

Introduction: Mobile medical and surgical camps are one of the means of providing medical and surgical facilities to people living in rural areas of developing country like Nepal.

Methods: An observational cross-sectional descriptive retrospective study was done collecting data from surgical camps done by Nepali Army in six years from February 2013 to February 2019 AD. Total number of surgical cases requiring anaesthesia along with type of anaesthesia, American Society of Anaesthesiologist physical status classification and anaesthesia related complications were collected.

Results: In a six year period, total 12 mobile surgical camps were conducted by Nepali Army. Out of which, two were done in collaboration with Ministry of Health, Government of Nepal. Total 703 surgical cases were conducted. Out of which, 583 were general surgical cases and 120 were gynaecological cases. 262 cases were done in local anaesthesia, 242 cases were done in spinal anaesthesia, 108 cases were done in total intravenous anaesthesia and 91 cases were done in general anaesthesia. Hypotension, nausea, vomiting, shivering, failed spinal and difficult airway were the complications noticed during intra-operative and postoperative period.

Conclusions: Surgical outreach camps are beneficial in providing surgical care to unaffordable people living in rural and remote areas where health care facilities are limited and inaccessible. Safety of patient is the key concern in such camps. Proper organised plan is required selecting target group of populations with target surgeries per day for successful conduction of safe surgeries in such camps.

Rejected
Authors: Rana Shavana Rajya Laxmi
Published: January 2020

Rejection is faced by all of us; it is upon us to take it in one’s stride. If we consider rejection as a step in scientific writing, handling a rejection becomes easy and bearable. The very fact that most of the well known scientific authors have faced rejection somewhere down their academic career would perhaps help most of the academicians to take rejections logically. It is no wonder to many academicians that even Albert Einstein had been rejected for the post of Lecturer in numerous universities and worked as a clerk in a Patent office.1

The letter of rejection might state various reasons, common ones being lack of originality, incomprehensibility, poor scientific reasoning or unsuitable to that journal’s readership. No matter what the reason may have been, a set format of polite rejection mail from the most journals is quite familiar to most of us. This is a very important guiding principle for improvement of the quality of the article. This should be taken as a stepping-stone in the process of acceptance for publication.

The rejection rate of journals can vary tremendously. Generally, the higher the academic value of the journal, the higher the rejection rate. Most of us are discouraged by the higher rejection of the highly reputed journals. Many reputed journals have a rejection rate of 80 to 85%.2 However, the best part of highly reputed journals is that along with their polite mail of rejection, they also send the expert opinion of the reviewers why the particular article would have been rejected. In this regards, it is sometimes more logical to consider such reputed journals for ones submission. If the rejection mail arrives in less than a month, then it is probable that it was not sent to a reviewer and was rejected by the editors, in view of basic formatting not being in consonant with the journal or the substance matter not fitting in with the scope of the journal.

It is upon the author to decide whether to reform the article or send it to a new journal after the rejection. Generally, the pool of reviewers for many reputed journals have many names common. So, if the author does not modify the article and submit it to another journal, very likely, the reviewer’s comments also remain the same. Usually if the reviewer has sent some comments, amending the article according to the critical comments and resubmitting is wise and more scientific rather than hunting exasperatedly for optional journals. It is always advisable to rethink and spend some time reforming your article according to the journal’s guidelines and the reviewer checklists. And many of the times, it would be much prudent to take the reviewer’s comments seriously and it would surprise the author how his/her article can turn out so beautiful after modifications. If you are not ready to accept the reviewer’s comments, it is better to give reason validating your writing but continuous letter of rejection demands serious rethinking of the whole approach.

Untuk mengurangi beban mati pada konstruksi rumah, dikembangkan produk genteng dari bahan Concrete foam (Beton busa) diperkuat serat tandan kosong kelapa sawit (TKKS) sebagai bahan ringan alternatif. Beton busa merupakan jenis beton ringan yang menggunakan foam dan serat TKKS sebagai agregat ringannya. Beton busa telah diteliti dan dikembangkan menjadi berbagai produk bangunan ringan, salah satunya ialah genteng ringan. Fenomena hujan es dapat merusak pesawat, mobil, dan tentu saja atap rumah. Penelitian ini bertujuan untuk menganalisa respon mekanik produk genteng dari material komposit beton busa diperkuat serat TKKS akibat beban impak yang diakibatkan hujan es. Untuk memverifikasi hasil pengukuran, dilakukan pula simulasi beban impak menggunakan software Ansys. Pengujian impak hail (hujan es), dilakukan menggunakan alat uji kompresor impak (KOMPAK) dengan batang aluminium sebagai impactor-nya. Pengukuran tegangan pada spesimen diukur dengan menggunakan strain gages untuk beton. Pengujian divariasikan dengan jarak impak striker dan impactor. Dari penelitian ini diperoleh hasil bahwa produk genteng tidak mengalami kegagalan hingga kecepatan impak 14 m/detik. Pada jarak impak 60 mm (kecepatan impak 16,09 m/detik) genteng mulai mengalami kerusakan, dengan tegangan yang terukur pada strain gage sebesar 1,07 MPa. Dari hasil simulasi beban impak dengan Ansys, diperoleh tegangan normal arah sumbu X sebesar 1,0726 MPa.

Published: January 2020

e-KTP merupakan cara baru yang dilakukan oleh pemerintah dengan tujuan membangun database kependudukan secara nasional untuk mendukung pelaksanaan e-Government yang efektif, efisien dan transparan. Namun pada kenyataannya, fungsi e-KTP masih sebatas untuk identitas kependudukan saja, padahal masih banyak sumber daya data lainnya yang dapat dimanfaatkan dalam mengelola data kependudukan. Tujuan penelitian ini adalah untuk mendeskripsikan implementasi program dan pemanfaatan e-KTP yang terintegrasi di Kabupaten Sambas serta mengidentifikasi faktor penghambat dan pendukung dalam implementasi program dan pemanfaatan e-KTP yang terintegrasi tersebut. Penelitian dilaksanakan di Kabupaten Sambas yaitu pada Disdukcapil , BPJS, KUA Kecamatan Tekarang, Kecamatan Tekarang dan Desa Merubung. Penelitian bersifat deskriptif kualitatif. Pengumpulan data dilakukan dengan teknik wawancara. Teknik analisa dalam penelitian ini adalah analisis deskriptif. Hasil penelitian memperlihatkan bahwa peran pemerintah dalam memberikan pemahaman kepada masyarakat sangat baik, yaitu berupa sosialisasi yang gencar dilakukan hingga daerah perbatasan. Hal ini dibuktikan dengan jumlah persentase perekaman yang tinggi. Namun, keberhasilan tersebut masih menyisakan beberapa hambatan antara lain sumber daya manusia yang kurang memadai, minimnya alat perekaman, keterbatasan jaringan internet, sering terjadi pemadaman listrik, keterbatasan anggaran, keterbatasan blangko perekaman, jangkauan antar wilayah yang cukup jauh dan dialek penduduk perbatasan yang condong ke negara Malaysia sehingga susah untuk dibedakan serta struktur birokrasi yang panjang dalam proses pembuatan e-KTP. Pemanfaatan e-KTP belum optimal karena tidak didukung kuat oleh sinergitas aplikasi yang terintegrasi pada masing-masing lembaga pemerintahan dalam  pelayanan publik.

Most research interests focused on the development of non-toxic and environmentally green corrosion inhibitors. In this work, three environment friendly corrosion inhibitors based on cinnamaldehyde named N,N-dimethyl-N-(2-((3-phenylallylidene) amino)ethyl)octan-1-aminiumbromide (PhAEO), N,N-dimethyl-N-(2-((3-phenyl allylidene) amino)ethyl)decan-1-aminiumbromide (PhAED) and N,N-dimethyl-N-(2- ((3-phenylallylidene)amino)ethyl)dodecan-1-aminiumbromide (PhAEDD) were prepared. The chemical structures of the prepared green corrosion inhibitors were confirmed by FTIR and1H-NMR. Their surface activities were studied using different surface parameters. The corrosi on inhibition efficiency of these compounds in 1 M hydrochloric acid on carbon steel was investigated chemically using weight loss method at varing temperatures (30, 45, and 60°C) and electrochemically at 30°C using potentiodynamic polarization measurements and electrochemical impedance spectroscopy. The carbon steel surface was characte rized by Scanning Electron Microscopy. The results show that the prepared compounds have a significant inhibiting effect on the corrosion of carbon steel and protection efficiencies up to 92%. These results were supported by theoretical studies using Density Functional Theory (DFT), which was used to calculate some quantum chemical descriptors, particularly the energy of Highest Occupied Molecular Orbital (EHOMO), Lowest Unoccupied Molecular Orbital (ELUMO) and the energy band gap ΔEgap. Fukui indices f+and f–for local nucleophilic and electrophilic attacks were considered. The theoretical results show that the behavior of the energy gap and adsorption energy is consistent with the sequence of the percent inhibition efficiency obtained by chemical and electrochemical measurements.

Published: January 2020

Effect of optically active dopants on the morphologic and optical refracting properties of the lyotropic liquid crystalline mesophase with anisometric micelles has been investigated. Lyotropic lamellar mesophases, which are formed by the plate-like micelles of quasi-indef inite diameter, were objects of the investigations. Wine acid (WA) and tartaric acid (TA) were used as the optically active dopants. Texture transformations under influence of an external magnetic field and time and temperature changes of these textures for quaternary mixtures with various concentrations of the optically active dopants have been studied. Unusual textures with the spherical microdroplet formations have been found and studied. The optical refracting properties of ternary and quaternar y lyotropic systems vs. temperature and concentration were investigated.
The Concept of "Ethno-Cultural Design" in the System of Project Methodology of Interpretation of Socio-Political Reality
Authors: Gorbachev Mikhail Valerevich
Published: January 2020

The Concept «design» is one of the most popular and demanded in modern social and humanitarian Sciences. It is used to explain the controlled processes in the economic, political, social and spiritual spheres of public life. As a result, in each of the designated areas, their own types of design and project activities are formed, which have a unique specificity that requires detailed analysis. One of these types of design is ethnocultural design. The aim of the article is to interpret the concept of «ethno-cultural projection» as an organic part of the project theory of explaining social changes. The realization of this goal is possible by solving the following tasks. First, the classification of the main types of design, which are presented in the system of social and humanitarian knowledge. Secondly, the definition of the features and functionality of «ethno-cultural design». The methods of the article are based on the combination of the provisions of the civilizational theory with the principles of the project approach to the interpretation of socio-political reality. As a result of the analysis, it was revealed that the concept of «ethno-cultural design» is an integral part of the project methodology of interpretation of modern socio-political reality. At the same time, being a part of modern project methodology, this concept acts as an independent ideological and instrumental construction. Thus, it is formed around its own industry features and characteristics. The article concludes that ethno-cultural design is able to claim the status of an independent direction within the project methodology. The achievement of such a position is possible through the formulation of its own conceptual and categorical apparatus, the conditions for the implementation of project work, the mechanisms of project activity.
