Energy and gas dynamic characteristics of ionization nitrogen installations of industrial type
Authors: Bosyakov M. N. , Kozlov A. A.
Published: November 2018

The work provides the analysis of power characteristics of the industrial equipment – ionic nitriding applications – with different types of vacuum chambers – with hot and cold walls. The calculations results and experimental researches of thermal balance of the system “melt-wall chamber” at the process of plasma nitration for industrial applications are given. The work examines the influence of heat-shielding screens quantity in the applications with cold walls on the internal screen temperature and power of thermal losses at warming up parts melt and at its isothermal endurance. It has been displayed the significant influence of the discharge chamber geometry on the discharge power value which is necessary for the melt warming up and its exposition at the certain temperature – the less are geometrical sizes of the chamber (diameter and height), the smaller is the power of the smoldering discharge which is required for ensuring necessary melt temperature. It is shown that at sufficient melt parts distance from the chamber walls, the voltage drop on the skeleton of the smoldering discharge can be tens volts that causes the decrease of cathodic falling potential and, respectively, the increase of the electric power which is required to maintain necessary melt temperature in comparison to melt which is as close as possible to chamber walls. It leads to the fact that at more dense loading, smaller specific consumption of the electric power to ensure the necessary depth of the nitrated layer is required; at the same time the specific energy consumptions by the melt temperature of 525–530 °C are 0.6–1.6 kW∙h/kg, depending on the loading extent of the chamber. It has been displayed that at ionic nitration, the value of working gas pressure must provide the deviance of the smoldering discharge i. e. the whole area the cathode –melt must be captured by the discharge luminescence.

At present, the technology of diamond blade whetting with nano-sized roughness is widely used at the manufaсturing of metal-optical products, first of all, mirror-reflectors for “transportation” of powerful laser energy flows. Optimum material for mirror-reflectors is an aluminum alloy AMg2, which surface purity, is affected by the quality of preliminary mechanical heat treatment during superfinishing treatment by diamond whetting.

Preliminary machining of the surface with a carbide cutter and finishing with a diamond cutter (with a radius of curvature of the blade less than 0.05 μm) were performed on a precision lathe of the MK 6501 model with a vertical spindle position on an air bearing. Thermal treatment was carried out in the laboratory electric furnace SNOL 58/350. Various modes of preliminary heat treatment, machining with a carbide cutter and finishing with a diamond cutter of substrates (20×20×7 mm3) were tested. The surface state analysis was carried out using the PMT-3 microhardness tester, the SolverPro P47 atomic-force microscope (AFM), and the experimental probe-electrometry device. The control of the electrophysical parameters of the surface was carried out by recording the distribution of the electron work function (RWF) by the contact potential difference with the processing by the microprocessor measuring transducer of electrostatic potentials. The recorded changes in the RWF characterize the physic-chemical and mechanical parameters of the surface of mirrors and indicate the presence of a different type and nature of defects.

Modified preliminary mechanical-thermal treatment allowed to improve the cleanliness of surface treatment of substrates. Finishing nanoscale diamond blade processing, including the complete removal of the surface layer that was disturbed by previous operations, bring to the greatest possible improvement in the quality of the surface in terms of the uniformity of the distribution of its electrophysical properties. As a result, according to the values and changes of the RWF, achievement of the specified performance characteristics of the product surface was monitored in order to optimize the technological processing modes in accordance with the functional designations of the devices.

The methods for increasing the efficiency of nanoscale diamond blade processing and performing researches of the electrophysical properties of the surface to control defects in the manufacture of metal reflector mirrors with high reflectivity and radiation strength for operation under extreme conditions.

Trust discourse in existential philosophy
Authors: Kozhemiakina O. N.
Published: November 2018

The conceptual analysis of the problematization of the crisis of trust in the context of existential philosophy is performed in the article, paying special attention to the specificity of the ambivalent interpretation of the ontological and phenomenological levels of trust as the value basis for social interaction. Addressing the works of K. Jaspers, M. Buber, O. F. Bollnov, N. Abbagnano, the ways of overcoming the crisis bases of trust and the conditions of the “possibility of possibilities” of trust as a positive existential of responsible coexistence are analyzed. The conceptualization of trust as an existential self-determination in the horizons of reliability of world and readiness for vulnerability is presented.

An existential analytics of the phenomenological level of trust in the interpretation of strategies of critical optimism and suspicion practices is proposed, which allowed us to consider the constructive and destructive effects of trust in terms of meaningful problems of choice, fear, anxiety, concern, freedom, responsibility in the “trust-to-the-world” and “trust-to-Other” horizons, conceptualizing internal and external resources of basic expectations of reliability, security, optimistic openness and pulsating humanity.

AbstrakPerkawinan merupakan peristiwa penting dalam kehidupan manusia. Dimana perkawinan adalah ikatan lahir dan batin antara seorang pria dan seorang wanita untuk menjadi suami istri yang bertujuan membentuk keluarga bahagia kekal abadi berdasarkan Ketuhanan Yang Maha Esa. Pada dasarnya azas perkawinan di Indonesia adalah azas monogami. Meskipun poligami tidak dilarang selama memenuhi syarat dan ketentuan yang berlaku sesuai dengan Pasal 4 ayat (1) dan ayat (2) Undang-Undang Nomor 1 Tahun 1974 tentang Perkawinan. Namun pada praktek dalam Pengadilan Agama, Penetapan Majelis Hakim sering kalitidak sesuai dengan ketentuan dari ijin Poligami itu sendiri yang telah ditentukan di dalam Pasal 4 dan Pasal 5 UU No. 1 Tahun 1974 mengenai syarat absolut dan alternatif dalam poligami. Penelitian ini menggunakan metodeyuridis normatif yaitu dengan cara meneliti sumber pustaka an pada data sekunder saja, yang berupa norma hukum tertulis. Harapan yang ingin disampaikan peneliti dalam penelitian ini adalah agar Majelis Hakim khususnya di Pengadilan Agama lebih jeli dan teliti dalam memberikan ijin poligami terhadap pemohon pelaku poligami.

Entrepreneurial opportunity decisions under uncertainty: Recognizing the complementing role of personality traits and cognitive skills
Authors: Mensah Emmanuel Kwasi , Asamoah Lawrence Adu , Sadeghi Vahid Jafari
Published: November 2018

Entrepreneurship research on decision making under uncertainty has focused largely on the effect
of uncertainty on the entrepreneurial actions while attempt at the individual level particularly,
from the cognitive framework seeks to explain why actions differ. Scholarly efforts have also been
made on what informs entrepreneurial actions from the perspective of the entrepreneur’s
personal attributes. However, no integrated approach is offered in the literature to study how
cognitive skills and personality traits complement each other. In this paper, we consider how
cognitive skills and personality traits affect an entrepreneur’s decision to discover or create
opportunities under uncertainty. Specifically, we examine the complementary role of personality
traits and cognitive skills towards opportunity decisions. We provide a conceptual basis for a
broader perspective on behaviors and cognitions that motivate or hinder entrepreneurial actions
while at the same time positioning the entrepreneur’s decision at the core of the decision theory.
Propositions regarding the application of some selected personality traits and cognitive skills and
their complementarity are presented and discussed.
Semantic and morphological cross-word priming during sentence reading
Authors: Marjanovic Katarina , Crepaldi Davide
Published: November 2018

Our current understanding of visual word identification is difficult to extend to text reading—both experiments and theories focus primarily, if not exclusively, on out-of-context individual words. Here, we try to fill this gap by studying cross-word semantic and morphological priming within sentences in a natural reading, eye tracking experiment. We find that words are skipped more when they are preceded in the sentence by semantically related primes. Also, cross-word semantic priming manifests itself in later (e.g., gaze duration), but not in earlier (e.g., first-of-many fixations) indexes of eye movement on the target words. We also find that semantic priming is not modulated by the morphological agreement between primes and targets; and that morphological agreement does not yield any priming per se. These results point to independent lexical-semantic and morphological processing during sentence reading, and suggest cross-word reset for the latter, but not for the former.

This study aims to maintain the authenticity of the data to assure the recipient that the data is free from modifications made by other parties, and if there is a modification to the data, then the recipient will know that the data is no longer maintained authenticity. The digital signature technique is used by using a combination of the MD5 algorithm as a hash function algorithm to generate the message digest, and ElGamal algorithm as a public key algorithm, with the combination of the two algorithms, will be generated the digital signature of each data that will be preserved. The ElGamal algorithm is used to encrypt message digest from the process of the MD5 algorithm to files where the digital signature is the result of encryption of message digest. The private key is used for the encryption process, while the public key is used to process the digital signature description when the file testing process is received. The results of the combination of the two algorithms are implemented in a web-based application that is built using the PHP programming language. Data used as input can be in the form of files of any format that has a maximum size of 100 MB. The results showed that a combination of the two algorithms provides digital signatures that have a high level of security and with reasonably fast processing time.

This paper aims at exploring adjective reduplication in Toba Batak language. The major issue in this descriptive microlinguistic study is the formations of adjective reduplication. There are some urgent points under discussion, namely, the identification of the morpheme that form the formation of the adjective reduplication, the morphological processes of the word formation, and the meaning emerged as the result of the morphological processes. The result of the analysis shows that there are five types of adjective reduplication in Toba Batak language, they are, (1) full adjective reduplication, (2) partial adjective reduplication with prefix mar- and um-, (3) partial adjective reduplication with infix –um-, (4) partial adjective reduplication with suffix –an, -hian, and –an, and (5) partial adjective reduplication with marsi-i, ha-assa, ma-hu, pa-hu, sa-na, and um-hian. The meanings of the adjective reduplication can be grouped into eight, namely, (1) refers to the basic meaning of the base adjective, (2) in the condition as mentioned in the base adjective, (3) has the characteristic as mentioned in the base adjective, (4) shows degree of comparison, (5) shows differences, (6) shows that something or some one is just so so .... as mentioned in the base adjective, (7) shows that something or some one is too ..., and (8) expresses superlative degree about something or some one.

Published: November 2018

Tujuan saya menulis bahan ini adalah sebagai pengantar diskusi kita tentang mengembangkan organisasi ini di Universitas Negeri Padang. Sebagai langkah awal dari pencarian benang merah dari beragamnya ide kita yang berserakan. Tulisan ini dipandu oleh cara pandang teori difusi inovasi dari Gabriel Tarde di awal 1900-an yang selanjutnya dikembangkan oleh Everett M. Roger pada 1960-an.Cara pandang difusi inovasi digunakan untuk melihat sejauh mana individu atau suatu kelompok dalam mengadopsi sebuah inovasi. Inovasi yang dimaksud adalah gagasan, pengetahuan, dan teknologi. Dalam konteks organisasi kita (GMNI di UNP) berarti sejauh mana gagasan nasionalisme diadopsi oleh mahasiswa. Atau sejauh mana mahasiswa di UNP mengenal GMNI dari aspek keorganisasian, aktivitas, dan perannya pada organisasi kemahasiswaan di UNP. Bagian ini merupakan pembatasan yang diusulkan melalui tulisan ini.

Regional autonomy (decentralization) is the regional authority to regulate and manage the interests of society at its initiative based on community aspiration and according to laws and regulation. One aspect of local government that must be regulated carefully is the financial management area. To analyze the performance of local governments in managing local finances can be done with the financial ratio analysis. The financial ratios used include the effectiveness ratios, efficiency ratio, growth ratio and the ratio of independence. The purpose of this study is to determine the financial performance of Medan. Government significant effect on the ratio of independence. The population in this study is Medan Realization Report Government Budget in which samples are taken four years (2010/2013 in months January to December). The variables studied include the ratio of effectiveness, efficiency ratio and growth ratio as independent variables as well as the ratio of independence as a dependent variable. The results of the regression analysis showed that the ratio of effectiveness, effectiveness ratio, and growth ratio is evident from the 0,000 probability value of <0.05. Partial, effectiveness ratio has significantly influenced the ratio of independence. However, efficiency ratio and growth rate do not significantly influence the ratio of independence (budget financial field municipal government). Analysis of the coefficient of determination (R2) shows the number of 0.452 or equal to 45.2% which changes the city government performance ratio by the effect ratio, efficiency ratio and growth ratio, while the remaining 54.8% are likely influenced by other variables not examined in this study there are activity ratio, debt service cover ratio.

Published: November 2018

Computer security aims to help users prevent fraud or detect fraud in an information-based system. The information must be secured to be free from threats. Cryptographic techniques can prevent data theft. One cryptographic algorithm is Hill Cipher. This algorithm is one symmetric cryptography algorithm. The Hill Cipher algorithm uses an m x m sized matrix as the key to encryption and decryption. The fundamental matrix theory used in Hill Cipher is multiplication between matrices and inverses the matrix. Hill Cipher has two types of matrices in general, 2 x 2 and 3 x 3. This study discusses the order 2 x 2. The application of Hill Cipher in text-shaped media is highly recommended because it has fast encryption and decryption speeds. This method is very good at securing data that will be transmitted on an open network.
Compression Rate Comparison between Elias Delta and Unary Codes
Authors: Siahaan Andysah Putera Utama
Published: November 2018

Compression is significant in data storage. Existing data is in desperate need of a reduction technique so that the data can be stored efficiently. Compression is useful because it helps reduce the use of hard disk storage. Also, compression is useful for reducing transmission costs for sending data on the network. There are many methods used to do compression. This study contains a comparison of two methods of compression. The Elias Delta and Unary algorithms are the two algorithms chosen to compare in this study. Both of these algorithms have different work processes. The results of both are also very competitive in data compression. In different data, the Elias Delta algorithm is superior in storing space during compression, and the Unary algorithm is weak in compression. On the other hand, the Unary algorithm is superior in storing data, while Elias Delta algorithm loses in storing data. The result of both algorithms has different performance using different data.
