Published: June 2018

Keuntungan koperasi sangat besar pengaruhnya terhadap total pinjaman yang dimilikinya. Hal ini yang menjadikan perhitungan suatu pinjaman yang dimiliki dibutuhkan untuk mengetahui total pinjaman terendah untuk menjaga nilai keuntungan suatu koperasi. Perhitungannya yang dilakukan menggunakan metode persamaan non – linear menurut Secant karena dalam penerapan metode ini hamper sama dengan Metode Persamaan Non – Linear menurut Newton Rapson yang tidak bisa digunakan untuk menghitung persamaan non – linear yang mengdekati titik puncak suatu grafik dan namun dalam metode ini perulangan perhitungan untuk iterasi hingga thresholdnya sudah ditentukan dahulu sehingga perulangan iterasi bisa dibatasi dengan nilai yang ditentukan dulu. Proses perhitungannya menggunakan Program Matlab.
Implementasi Test Driven Development Dalam Pengembangan Aplikasi Berbasis Web
Authors: Thohari Afandi Nur Aziz , Amalia Andika Elok
Published: June 2018

Sebuah perangkat lunak dikatakan siap untuk dipakai apabila sudah melalui tahap pengujian. Pada era pengembangan perangkat lunak dengan metodologi tradisional, pengujian dilakukan dengan cara mencoba satu persatu menu aplikasi ketika aplikasi yang dikembangkan sudah jadi. Cara pengujian tersebut akan membutuhkan waktu yang lama apabila developer mengerjakan proyek perangkat lunak dalam skala besar. Selain itu, cara tersebut juga tidak dapat menguji logika dan method dari suatu kelas. Salah satu metode pengembangan perangkat lunak yang dapat menghemat waktu pengujian, namun fungsionalitasnya tetap terjaga adalah test driven development (TDD). Pada metode TDD, pengembangan perangkat lunak dilakukan dengan membuat test case terlebih dahulu baru kemudian melakukan producing code. Pada penelitian ini, dikembangkan sebuah aplikasi web menggunakan TDD. Aplikasi web yang dikembangkan adalah berupa sistem informasi mengenai ulasan film lokal indonesia atau disebut Indonesia Movie Database (IMDB). Bahasa pemrograman web yang dipakai adalah ruby dengan menggunakan framework rails. Sedangkan alat yang dipakai untuk pengujian adalah Rspec. Hasil implementasi TDD membuktikan bahwa fungsi-fungsi dari aplikasi web yang dibangun dapat berkerja dengan baik. Selain itu kode program yang dihasilkan juga menjadi rapi dan mudah dibaca oleh pengembang lain karena menerapkan refactoring. Pengujian unit test menggunakan Rspec membantu pengembang dalam menangani kesalahan dan memudahkan menambah fitur baru dari aplikasi web.

Penelitian ini berjudul ”Pola Pengasuhan Orang Tua Dalam Upaya Pembentukan Kemandirian Anak Down Syndrome (studi deskriptif pola pengasuhan orang tua pada anak Down Syndrome yang bersekolah di kelas C1 SD-LB Yayasan Pembina Pendidikan Luar Biasa Bina Asih Cianjur). Penelitian ini bertujuan untuk menggambarkan bagaimana bentuk pola pengasuhan yang diterapkan orang tua terhadap anak Down Syndrome di kawasan Cianjur. Pola pengasuhan tersebut meliputi pola pengasuhan permisif, otoriter dan demokratis.Peneliti menggunakan pendekatan penelitian kualitatif dengan metode penelitian studi deskriptif, sedangkan instrumen yang digunakan dalam pengumpulan data adalah pedoman wawancara, pedoman observasi, dan pedoman studi dokumentasi. Teknik yang digunakan adalah wawancara mendalam, observasi non-partisipatif, dan studi kepustakaan. Informan dalam penelitian ini berjumlah 8 orang yaitu, 6 orang dari pihak orang tua anak Down Syndrome. Dimana dalam penelitian ini akan di observasi dari 3 keluarga yang memiliki anak Down Syndrome, dengan masing-masing terdiri dari ayah dan ibu. Serta 2 orang dari pihak yayasan sebagai pihak yang memantau perkembangan kemandirian anak pada saat di sekolah.Hasil penelitian ini menunjukan bahwa pola pengasuhan orang tua berperan besar dalam pembentukan kemandirian anak Down Syndrome. Bentuk pola pengasuhan seperti apa, itulah yang akan membentuk karakter anak dan mempengaruhi kemandirian anak Down Syndrome, dikarenakan pola pembiasaan-pembiasaan yang diterapkan pada saat di rumah. Anak Down Syndrome memang membutuhkan perhatian lebih karena keterbatasannya. Namun hal ini tidak berarti mereka menjadi anak yang terus bergantung dan tidak mampu mandiri. Di satu sisi, mereka membutuhkan perhatian khusus, namun di sisi lain mereka juga perlu diberikan ruang untuk dapat mengembangkan kemampuannya. Maka dari itu, pola pengasuhan orang tua lah yang sangat berperan dalam hal ini.Dengan demikian, peneliti menyarankan suatu program pelatihan dan pembinaan bagi para orang tua anak Down Syndrome yaitu “Parenting Support”. Program ini bertujuan untuk memberikan pembinaan dan pelatihan bagi para orang tua agar mampu dalam merawat, mendidik dan menjaga anak Down Syndrome, guna mendukung pada ketercapaian pemenuhan kebutuhan dasar dan kemandirian mereka.

Published: June 2018

Social networking sites such as Facebook, Twitter and VKontakte, online stores such as eBay, Amazon and Alibaba as well as many other websites allow users to share their thoughts with their peers. Often those thoughts contain not only factual information, but also users’ opinion and feelings. This subjective information may be extracted using sentiment analysis methods, which are currently a topic of active research. Most studies are carried out on the basis of texts written in English, while other languages are being less researched. The present survey focuses on research conducted on the sentiment analysis for the Latvian and Russian languages.
Smooth Non-increasing Square Spatial Extents of Filters in Convolutional Layers of CNNs for Image Classification Problems
Authors: Romanuke Vadim V.
Published: June 2018

The present paper considers an open problem of setting hyperparameters for convolutional neural networks aimed at image classification. Since selecting filter spatial extents for convolutional layers is a topical problem, it is approximately solved by accumulating statistics of the neural network performance. The network architecture is taken on the basis of the MNIST database experience. The eight-layered architecture having four convolutional layers is nearly best suitable for classifying small and medium size images. Image databases are formed of grayscale images whose size range is 28 × 28 to 64 × 64 by step 2. Except for the filter spatial extents, the rest of those eight layer hyperparameters are unalterable, and they are chosen scrupulously based on rules of thumb. A sequence of possible filter spatial extents is generated for each size. Then sets of four filter spatial extents producing the best performance are extracted. The rule of this extraction that allows selecting the best filter spatial extents is formalized with two conditions. Mainly, difference between maximal and minimal extents must be as minimal as possible. No unit filter spatial extent is recommended. The secondary condition is that the filter spatial extents should constitute a non-increasing set. Validation on MNIST and CIFAR- 10 databases justifies such a solution, which can be extended for building convolutional neural network classifiers of colour and larger images.

Published: June 2018

The complications, especially those affecting microcirculation, exhibit great importance in the assessment and follow-up of patients with diabetes mellitus. Blood viscosity plays its most important role in the microcirculation where it contributes significantly to peripheral resistance and may cause sludging in the post capillary venules. The effect of whole blood viscosity in patients whit diabetic nephropaty is still unclear.

The aim of this study was to examine the influence of glicaemic control measured by glicated hemoglobin on rheological parameters, and especially on whole blood and plasma viscosity in patients with diabetic nephropaty. Blood viscosity is an important determinant of local flow characteristics. Blood exhibits shear thinning behavior: its viscosity decreases exponentially with increasing shear rates.

Estimation of whole blood and plasma viscosity was made on 42 patients, comparing different stages of diabetic nephropathy and with different values of glicated hemoglobin.

Depression of the regulatory mechanisms of microvascular blood flow as well as decreased tissue perfusion indicated the restricted blood flow in microcirculatory network in diabetic nephropathy. In conclusion blood viscosity was elevated in the patients with major organ complications and not in the patients without or with early complications, in correlation with poor glicaemic control.

Published: June 2018

The subclavian artery’s are two voluminous artery’s, left and right, which have their origin in a different way, the right one originating from the brahiocefalic trunk, and the left one directly from the aortic arch, at a distance that varies according to the origin of the left common carotid arteries.

Our study was made on computed tomography angiography, on which we have had the opportunity to examine the scans from Medimar Imagistic Center, in the County Clinical Hospital “Sf. Andrei” in Constanta, being carried out on a computer tomography GE LightSpeed 16 slice CT. Also, we had available angiography’s executed in the center for diagnosis Pozimed, being carried out on a computer tomography GE LightSpeed VCT64 Slice CT.

The variability of the findings in the anatomical parts of the subclavicular artery’s ostium, both as regards the size of the horizontal and vertical diameters, also their shape and as regards morfological relations with other branches of the aortic arch. The dimensions of the diameters vary according to sex, but it is a general rule that the dimensions are higher in male, the minimum and maximum values may be different in the two sexes.

Published: June 2018

Born in Trento (Italy, 2003) for the purpose of standardising vocabulary and units of humus form classification, after publishing a first synthetic classification e-book (Zanella et al. 2011) they do not cover all site conditions in the European area. Although having basic concepts and general lines, the European (and North American, Canadian, the Humus group decided to use its classification for handling global change (Zanella and Ascher-Jenull 2018). The process is detailed in many scientific articles published in three Special Issues (Humusica 1, 2 and 3) of the journal Applied Soil Ecology. Conceptually, the whole of Humusica answers three crucial questions: A) What is soil? Soil is a biological ecosystem. It recycles dead structures and implements mineral material, furnishing more or less re-elaborated organic, mineral and organic-mineral elements to support living organisms. Article chapters: 1. Essential vocabulary; 2. Soil covers all the Earth’s surfaces (soil as the seat of processes of organic matter storage and recycling); 3. Soil may be involved in the process of natural evolution (through organisms’ process of recycling biomass after death). B) If soil has a biogenic essence, how should it be classified to serve such managerial purposes as landscape exploitation or protection? A useful classification of soil should consider and propose useful references to biologically discriminate soil features. Article chapters: 4. Soil corresponds to a biogenic structure; 5. TerrHum, an App for classifying forest humipedons worldwide (a first attempt to use a smartphone as a field manual for humus form classification). C) How can this soil classification be used for handling the current global change? Using the collected knowledge about the biodiversity and functioning of natural (or semi-natural) soil for reconstructing the lost biodiversity/functioning of heavily exploited or degraded soils. Article chapters: 6. Agricultural soils correspond to simplified natural soils (comparison between natural and agricultural soils); 7. Organic waste and agricultural soils; 8. Is traditional agriculture economically sustainable? Comparing past traditional farm practices (in 1947) and contemporary intensive farm practices in the Venice province of Italy.

Classification of shallow and skeletal mountain soils with the WRB system on the example of the Trialeti Range, Lesser Caucasus (Georgia)
Authors: Kunchulia Ilia , Kakhadze Rusudan , Tsereteli Giuli , Ghambashidze Giorgi , Urushadze Teo
Published: June 2018

The aim of the paper is to evaluate the usefulness of the World Reference Base for Soil Resources (WRB) 2015 to classify shallow soils on mountains of the Trialeti Range, Lesser Caucasus, Georgia. The article also presents the evolution of the concept of Leptosols and of the qualifier “Leptic” and the diagnostic property of continuous rock. It also provides approaches to defining keys in the reference soil group (RSG) of Leptosols and identifying principal and supplementary qualifiers in WRB 2015 on example of soils of the Trialeti Range. The article gives few examples of classification for such shallow and stony soils with different set of qualifiers. Most of them fulfil the criteria of Leptosols and Regosols. These soils occur on the mountain range together with other RSGs (e.g. Pheozems). The authors propose to add the qualifier Technolithic to the list of Principal/Supplementary qualifiers of Leptosols.
Challenges of Soil Taxonomy and WRB in classifying soils: some examples from Iranian soils
Authors: Salehi Mohammad Hassan
Published: June 2018

The two most widely used soil classifications are the Soil Taxonomy (ST) and the World Reference Base for Soil Resources (WRB). The purpose of this paper is to clarify the differences and the similarities between ST and WRB in their current state, with some examples for representative soils in arid and semi-arid regions of Iran. Four representative pedons were classified and soil units from WRB were compared to those obtained by using ST at the family level. WRB could show the status of soils polluted by heavy metals through the Toxic qualifier and its subqualifiers. On the other hand, ST could indicate the status of shallow soils in our studied soils but it was not able to show gleyic conditions and the existence of a salic horizon because of the differences in its criteria compared to those of WRB. Special effort should be made to quantify various anthropogenic activities in upcoming editions of both classification systems.
Spatial variations in soil properties across ecotones: a short review
Authors: Marfo Theodore Danso , Resjek Klement , Vranova Valerie
Published: June 2018

Ecotones are considered as unique environments. The concepts of edge effect and ecotone species (flora and fauna) are widely used. Considering the fact that the majority of the species found in ecotones are usually at their physiologically determined limits of distribution, how they react to global climate changes becomes crucial. Ecotones are reputed to be more biologically diverse than areas close to them, and therefore possesses a high conservation value, yet little is known on how soil properties vary across ecotones. In this paper, we firstly highlighted the roles ecotones play in assessing the effect on global climate change, the mediatory role they play in the movement of material (water and nutrients) into and out of the region. Secondly, we reviewed studies on how soil properties change across ecotones and it is worthwhile to note that soil properties tend to differ across various ecotones (e.g. increasing pH and decreasing P & N across forest–glade ecotones, decreasing pH across ancient–recent forest ecotones) in a manner that defines the character of the ecotones existing.
The Soil Classification course in Russian universities: an important ingredient of education
Authors: Gerasimova Maria , Bezuglova Olga
Published: June 2018

The teaching of soil classification in the universities of Russia is being discussed as a comparatively new experience in the education of environmental science students. The lecture course (24–30 academic hours) changes in response to the inevitable changes in soil classification systems. In the introduction, the objectives and structure of soil classifications are outlined, and then a brief overview of the most well-known national systems is given, which is also important for understanding the difficulties, origin and problems of the International WRB system. The latter is the central point of the lecture course: its principles are explained, the main diagnostic features of Reference Soil Groups are communicated, and students are trained to use system basing on the descriptions of soil profiles and analytical data relating to them. As a result, students give WRB names to soils either by correlating with a name from the national system, which is familiar to them, or by looking at soil profile photos; in both cases morphological and analytical data are clarified by the teacher. Chernozem is used as an example for training. In the conclusion, the reasons to know soil classifications are specified, and they are differentiated for soil scientists, geochemists and geographers.

Most of the information on the evaluated educational portals is targeted at high school students. These websites present only basic content. The most frequent issues on the analyzed portals were: soil types and soil systematics, distribution of soils in Poland, definition of soil and also soil valuation classes. Websites addressed to university students constitute a decided minority, could be said, that even an exception. One of those is article on Wikipedia, which has the highest educational value among all analysed websites.
Soils in the Slovenian educational system
Authors: Repe Blaž
Published: June 2018

There is a considerable amount of confusion in soil-related topics at all levels of Slovenian education. The fundamental problem is the use of the term “soil”. We use several different terms for more or less the same natural phenomenon. Other problems include the lack of an official Slovenian soil classification, the occasional use of out-of-date soil topics in primary and secondary education, the inexpert use of soil names for soil types of the World, and very few higher education soil specialisations. There are a lot of existing initiatives to improve the current state, but there are still a lot of obstacles impeding this process.

Due to the increasing thermal-technical requirements for building structures, the insulating materials are developed. One of the modern thermal insulating materials is so-called aerogel. Unfortunately, this material is not used in the field of external thermal insulation composite systems because of its price and its properties. The aim of this paper is to present possibilities of using this insulating material in the civil engineering - specifically a usage of aerogel in the production of windows.
Investigating the Performance of Viscoelastic Dampers (VED) Under Nearfield Earthquakes with Directivity Feature
Authors: Vatanshenas Ali , Rohanimanesh Mohammad Sadegh , Mohammadiha Ehsan
Published: June 2018

One of the most important factors that make structures vulnerable to earthquakes is the short distance between structures and epicenter. Near-field earthquakes have special properties, such as increasing acceleration applied to the structure, which distinguishes them from far-field earthquakes. Therefore, the absorption of input energy for structures located near the faults is very important. Hence, by rotating the earthquake acceleration time history and comparing the resulting spectral acceleration response, the angle which applies the greatest force to the structure on the earthquake directivity side is obtained, and then the performance of a steel structure with viscoelastic dampers (VED) under near-field earthquakes with directivity feature is investigated. After analyzing the structure using nonlinear time history analysis, it was observed that the directivity phenomenon leads to significant increase in the force applied to the structure, but the viscoelastic dampers showed an acceptable performance in both states of with and without directivity.
Pinned - Fixed Beam - Column Resistance Verification According to European Standards
Authors: Prokop Jozef , Vičan Josef
Published: June 2018

Verification of beam-column resistance can be accomplished according to design approaches given in EN 1993-1-1 [1]. These approaches are derived from verification of single span beam with pinned end conditions subjected to compression and bending moments. In the case of different end conditions, the application of those approaches is not so accurate and more difficult. Therefore, the comparison of verification according to above standard EN 1993-1-1 [1] as well as EN 1999-1-1 [2] to results of experimental analyses of beam-columns having pinned-fixed end conditions subjected to an eccentric compressive force simulating the behaviour of columns integrated into frames is presented in this paper.

The article analyses parameters of the effect of high-speed trains on simple beam spanning bridge structures and suggests a technique of determining of the dynamic index to the live load. Reliability of the proposed methodology is confirmed by results of numerical simulation of high-speed train passage over spans with different speeds. The proposed algorithm of dynamic computation is based on a connection between maximum acceleration of the span in the resonance mode of vibrations and the main factors of stress-strain state. The methodology allows determining maximum and also minimum values of the main efforts in the construction that makes possible to perform endurance tests. It is noted that dynamic additions for the components of the stress-strain state (bending moments, transverse force and vertical deflections) are different. This condition determines the necessity for differentiated approach to evaluation of dynamic coefficients performing design verification of I and II groups of limiting state. The practical importance: the methodology of determining the dynamic coefficients allows making dynamic calculation and determining the main efforts in split beam spans without numerical simulation and direct dynamic analysis that significantly reduces the labour costs for design.

Published: June 2018

The paper deals with the lifetime of wooden poles, situated in the archaeological open-air museum Liptovská Mara - Havránok, which were erected outdoors about 12 years ago. It is aimed at diagnosing their condition using sonic tomography. The poles differ from each other in the location, anchorage, and positioning in terms of the terrain slope. Investigation was focused on the free-standing poles (quasi sacrifice poles) and the poles that are part of the fortification (gates and walls). Measurements were carried out using the device Fakopp ArborSonic 3D Sonic Tomograph that has 18 sensors. It measures the sonic response (sound velocity) in a tree stem. Sound wave velocity within sound wood depends on its species, moisture content, and the direction of measurement. Measurements brought remarkable results.

Published: June 2018

The paper presents numerical analysis of block made of three layers: concrete with I-shape rubber pads, space filled with air and concrete with embedded cross rubber pads, respectively. The block is subjected to the dynamic load. To the analysis as rubber the hyperelastic incompressible Zahorski material model was assumed. This material well describes the real material properties in the range of large elastic deformations. Embedded rubber pads provide an additional protection against the transversal dynamic load. ADINA software was utilized to perform numerical analysis of determining the percentage damping factor of rubber-concrete composite in comparison with block made of concrete.

Published: June 2018

Experimental studies of rectangular steel-concrete columns under centric compression with random eccentricity were conducted. The stress-strain state and the carrying capacity exhaustion have been assessed. The regression dependence is proposed to determine the maximum carrying capacity of such columns. The mathematical model takes into account the combined influence of the physical and geometric characteristics of the columns, such as their length, crosssectional area, casing thickness, prism strength of concrete, yield strength of steel, modulus of elasticity of both steel and concrete. The correspondence of the obtained model to the experimental data, as well as the significance of the regression parameters are confirmed by the Fisher and Student criteria.

This paper describes an image encryption algorithm which utilizes chaotic logistic map. Values generated by this map are used in two steps of algorithm which shuffles image pixels and then changes their intensities. Design of the encryption scheme considers possibility of various attacks, such as statistical, differential or phase space reconstruction attacks. Robustness against last mentioned type of attacks is introduced by selective skipping of values generated by the map. This skipping depends on key entered by user. The paper also verifies properties of proposed algorithm by common measures and by set of statistical tests that examine randomness of computed encrypted images. Results are compared with other approaches and they are also briefly discussed.

Published: June 2018

The paper presents a new original robust PID design method for non-minimum phase plants to achieve closed-loop performance prescribed by the process technologist in terms of settling time and maximum overshoot, respectively. The proposed design procedure has two steps: first, the uncertain system is identified using external harmonic excitation signal with frequency, second, the controller of the nominal system is designed for specified gain margin. A couple of parameters is obtained from the time domain performance specification using quadratic regression curves, the so-called performance Bparabolas so, as to simultaneously satisfy robust closed-loop stability conditions. The main benefits of the proposed method are universal applicability for systems with both fast and slow dominant dynamics as well as performance specification using time domain criteria. The proposed PID design method has been verified on a set of benchmark systems.

Authors: Šošić Darko , Stefanov Predrag
Published: June 2018

Configuration of distribution system can be changed manually or automatically, by changing the status of the respective switching elements, with the aim of reducing power losses, increase system reliability, or improving the power quality. When changing the status of switching equipment it is necessary to satisfy the requirement for the radial and connected structure of the distribution network. Using the single criteria optimization it is possible to improve one of the characteristics of the distribution network, on the other hand by using multicriteria optimization it is possible to find a network configuration that enhances multiple distribution system characteristics at the same time. In this paper, a modification of the multi-criteria Gray Wolf optimization algorithm is proposed in order to create an efficient algorithm that can be implemented in the management functions of smart grid concept of modern distribution systems. The proposed reconfiguration algorithm was tested on standard symmetrical IEEE 33 test distribution network.

Thanks to non-pollution and sustainability of wind energy, it has become the main source of power generation in the new era worldwide. However, the inherent random fluctuation and intermittency of wind power have negative effects on the safe and stable operation of power system and the quality of power. The key solving this problem is to improve the accuracy of wind speed prediction. In the paper, considering the forecasting accuracy is affected by many factors, we propose that, Principal Component Analysis (PCA) is combined with Independent Component Analysis (ICA) to process the sample, which can weaken the mutual interference between the various factors, extract accurately independent component reflected the characteristics of wind farm and achieve the purpose of improving the accuracy of wind speed prediction. At the same time, the adaptive and self-learning ability of neural network is more suitable for wind speed sequence prediction. The prediction results demonstrate that compared with the traditional neural network predicting model (RBF, BP, Elman), this model makes full use of the information provided by varieties of relevant factors, weakens the volatility of wind speed sequence and significantly enhances the short-term wind speed forecasting accuracy. The research work in the paper can help wind farm reasonably arrange the power dispatching plan, reduce the power operation cost and effectively boost the large-scale development and utilization of renewable energy.
