ON THE RESULTS OF STUDYING THE INFLUENCY OF VIBRATION-FLUCTUATIONS PROCESSES ON THE RESOURCE OF WELDED JOINTS OF MARINE STATIONARY PLATFORMS FOR OIL, GAS AND OTHER USEFUL MINERALS ON THE SHELF
Authors: Starokon Ivan
Published: June 2020

The study of the occurrence of resonant oscillations when the frequency spectrum from the hydrodynamic load coincides with the natural frequencies of the elements of the offshore platforms, as a result of which the acting stresses multiply, has a great practical importance. In the process of research it was found that the most loaded elements of the platform under such an impact are the supports. In this research, the degree of influence on the supports of the force arising due to the formation and breakdown of vortices during the flow around the supports with a fluid flow is estimated. A conclusion about the influence of vibrational-fluctuations processes on the resource of offshore stationary platforms is based on this research.
ABOUT OF THE METHOD OF DECREASE RAIL TRANSPORT IMPACT NOISE IN LOW FREQUENCY RANGE
Authors: Kolykhalin Vitaly
Published: June 2020

The method of decrease impact noise between of wheel pairs rail transport and rail joints being main sources of noise is analyzed. The spectrum of such noise reaches a maximum in an octave strip of 31,5 Hz and sharply decreases in a strip of 1 kHz. The practical implementation dipole effect can be received by formation a pair of the knock impulse sources when the direction of acoustical axes is along the railway under small angle. The compensatory effect when one rail joint for example right moves according left joint in other rail on the distance d having half of wave length of the basic low-frequency range of shock impulses is reached. The system of standing waves in the interval d by an antiphase pair of sources with coherent components in the basic frequency 31,5 Hz and odd harmonics is formed. The new additional effect to noise reduction by replacement the rectangular rail joint edges on the oblique-angled rail joints having 45 degree edge angle is carried out.
TRANSFORMATION OF SPECTRAL PECULIARITIES OF THE SOIL RESPONSE TO DYNAMIC IMPACTS OF VARYING VALUE

Published: June 2020

The aim of the work was the question of the prediction of soils and structures behavior during intensive impacts. Adequate study of nonlinearity, which is an immanent feature of natural phenomena, will make it possible to bring the corresponding anti-seismic measures closer to the real features of seismic effect manifestations during strong earthquakes. To assess the level of soil inelasticity directly, a special scheme of experimental research with a gas-dynamic pulse source GSK-6M was used. It has been determined that a high-frequency component prevails in the vibration spectrum of weak soil, caused by a close oscillator of high-energy source, which quickly attenuates with distance. A low-frequency component dominates in the vibration spectrum in the process of the influence of remote oscillator on the same soil. Analysis of the records of strong and destructive earthquakes, as well as the analysis of specially conducted experimental effects, showed that the area of spectra of the corresponding ground vibrations is not constant at inelastic phenomena. The study of formulas based on the consideration of various physical characteristics of soils and motion indicators in order to calculate the seismic intensity increment was conducted. The limits of physical applicability of the formulas developed based on taking into account various indicators of soil movements are established. The application of the formula, which considers the weighted average frequencies and amplitudes of ground vibrations (which characterize the non-linearity/inelasticity of soils), is physically most reasonable.
Extending UML Use Case Diagrams to Represent Non-Interactive Functional Requirements
Authors: Iqbal Saqib , Al-Azzoni Issam , Allen Gary , Ullah Khan Hikmat
Published: June 2020

Background: The comprehensive representation of functional requirements is a crucial activity in the analysis phase of the software development life cycle. Representation of a complete set of functional requirements helps in tracing business goals effectively throughout the development life cycle. Use case modelling is one of the most widely-used methods to represent and document functional requirements of the system. Practitioners exploit use case modelling to represent interactive functional requirements of the system while overlooking some of the non-interactive functional requirements. The non-interactive functional requirements are the ones which are performed by the system without an initiation by the user, for instance, notifying something to the user or creating an internal backup.

Aim: This paper addresses the representation of non-interactive requirements along with interactive ones (use cases) in one model. This paper calls such requirements `operation cases’ and proposes a new set of graphical and textual notations to represent them.

Method: The proposed notations have been applied on a case study and have also been empirically evaluated to demonstrate the effectiveness of the new notations in capturing non-interactive functional requirements.

Results and Conclusion: The results of the evaluation indicate that the representation of operation cases helps in documenting a complete set of functional requirements, which ultimately results in a comprehensive translation of requirements into design.
Evolutionary Stable Strategies in Games with Fuzzy Payoffs
Authors: Haozhen Situ
Published: June 2020

Evolutionarily stable strategy (ESS) is a key concept in evolutionary game theory. ESS provides an evolutionary stability criterion for biological, social and economical behaviors. In this paper, we develop a new approach to evaluate ESS in symmetric two player games with fuzzy payoffs. Particularly, every strategy is assigned a fuzzy membership that describes to what degree it is an ESS in presence of uncertainty. The fuzzy set of ESS characterize the nature of ESS. The proposed approach avoids loss of any information that happens by the defuzzification method in games and handles uncertainty of payoffs through all steps of finding an ESS. We use the satisfaction function to compare fuzzy payoffs, and adopts the fuzzy decision rule to obtain the membership function of the fuzzy set of ESS. The theorem shows the relation between fuzzy ESS and fuzzy Nash equilibrium. The numerical results illustrate the proposed method is an appropriate generalization of ESS to fuzzy payoff games.
The Beveridge Curve in the Housing Market
Authors: Gaetano Lisi
Published: June 2020

As opposed to a recent criticism (according to which a model à la Pissarides inherently generates a downward sloping Beveridge curve), this short theoretical paper shows that a baseline search-and-matching model is able to take into account the main distinctive features of the housing market, thus generating an upward sloping Beveridge curve.

Published: June 2020

Introdução: A periodização no treinamento de força é necessária para obtenção de maiores ganhos das diferentes manifestações da força à medida que o treinamento avança.

Objetivo: Comparar dois diferentes modelos de periodização sobre a força máxima e potência utilizando por um período de 24 semanas.

Métodos: Estudo experimental, com amostra por conveniência, do qual participaram 12 jovens adultos (20-45 anos), de ambos os sexos. Os participantes foram aleatoriamente alocados nos dois tipos de intervenção: periodização ondulatória semanal (POS) e periodização ondulatória diária (POD). A intervenção teve a duração de 24 semanas.

Resultados: Tanto POD como POS apresentaram melhorias para a força, porém na POD os ganhos foram observados a partir da semana 8 (p = 0,003) e POS a partir da semana 16 (p = 0,004) sem diferenças significativas para os testes de potência. Quanto às diferenças intergrupos, foi observado um tamanho do efeito médio (d = 0,512) na semana 16 para a POD quando comparada à POS no leg press 45º. Para potência, foi observado tamanho do efeito médio no SJT no período pós (d = 0,549) para a POS se comparada à POD.

Conclusão: Conclui-se que, comparando-se os métodos POS e POD para otimizar ganhos de força, a POD é mais eficiente, porém, se o objetivo for melhorar o desempenho da potência, a POS pode ser a melhor estratégia.

THE ISSUE OF THE RUSSIAN TRADITIONS lawmaking In the XVII century
Authors: Ельчанинова Ольга Юрьевна
Published: June 2020

Вопросы познания правотворческой традиции XVII в., ее диалектической связи с факторами общественного развития нуждаются в дальнейшем изучении в отечественной правовой доктрине. Исследование эволюции отечественного правотворческого процесса предопределило обращение автора статьи к изучению его субъектов, порядка и результатов. Автором показано, что появление большого массива правового материала вызывало потребность в совершенствовании способов и приемов создания правовых норм, навыков их формулирования и толкования. Результатом систематизации законодательства стало Соборное уложение, которое консолидировало огромный массив актов, изданных различными субъектами правотворчества, регламентирующих различные сферы общественных отношений. Сделан вывод относительно того, что именно в XVII в. стало складываться паритетное соотношение между обычным правом и законом. Этот период можно считать началом нового этапа эволюции отечественного правотворческого процесса. В рамках исследования применялся диалектический подход, метод ретроспективного анализа, метод систематизации и др.

In the domestic legal doctrine, issues of knowledge of the law-making tradition of the 17th century, its dialectical connection with factors of social development need further study. A study of the evolution of the domestic law-making process predetermined the appeal of the author of the article to the study of its subjects, order and results. The author shows that the emergence of a large array of legal material caused the need to improve the methods and techniques of creating legal norms, the skills of their formulation and interpretation. The result of the systematization of legislation was the Council Code, which consolidated a huge array of acts issued by various subjects of lawmaking that govern various spheres of public relations. The conclusion is made about what exactly in the XVII century. a parity relationship has developed between customary law and law. This period can be considered the beginning of a new stage in the evolution of the domestic law-making process. The study used the dialectic approach, the retrospective analysis method, the systematization method, etc.
A 3D-polyphenylalanine network inside porous alumina: Synthesis and characterization of an inorganic–organic composite membrane
Authors: Stott Jonathan , Schneider Jörg J
Published: June 2020

Surface functionalization of porous materials allows for the introduction of additional functionality coupled with high mechanical stability of functionalized inner pores. Herein, we investigate the surface-initiated ring-opening polymerization (SI-ROP) of phenylalanine-N-carboxyanhydride (PA-NCA) in porous alumina membranes (ALOX-membranes) with respect to different solvent mixtures (tetrahydrofuran (THF) and dichloromethane (DCM)). It was found that increasing the volume fraction of DCM leads to an increasing amount of fibrillar polymer structures within the porous ALOX-membrane. A three-dimensional fibrillar network with intrinsic porosity was formed in DCM, whereas in THF, a dense and smooth polypeptide film was observed. A post-treatment with a mixture of chloroform and dichloroacetic acid leads to rearrangement of the morphology of the grafted polymer films. The analysis by scanning electron microscopy (SEM), near-infrared spectroscopy (NIR) and contact angle measurements (CA) reveals a change in morphology of the grafted polymer films, which is due to the rearrangement of the secondary structure of the polypeptides. No significant loss of the surface-grafted polypeptides was determined by thermogravimetric (TG) measurements, which indicates that the change in morphology of the polymer films is solely a result of a conformational change of the surface-grafted polypeptides. Furthermore, adsorption of a test analyte (chloroanilic acid) was investigated with respect to different polymer functionalization schemes for reversed-phase solid phase extraction applications. The adsorption capability of the functionalized composite membrane was increased from 16.7% to 38.1% compared to the native ALOX-membrane.

The duration of the operation, the volume of blood loss, the frequency and nature of intra- and postoperative complications were evaluated.Conclusion: laparoscopic access is accompanied by a smaller amount of blood loss, decrease of frequency of early postoperative complications, contributes to more comfortable postoperative period with early activation, less severe pain syndrome and leads to a reduction in the duration of inpatient treatment.
‘Byron Pasha’ in Istanbul with Mozart and Rossini: The Seductions of Ottoman Sovereignty
Authors: Pal-Lapinski Piya
Published: June 2020

While much critical attention has focused on Byron’s involvement with Greece, less work has been done on his response to Istanbul and the Ottoman Empire. In Britain and Europe, Byron’s literary representations of Ottoman power were preceded and paralleled by a rich tradition of the heroic, and often tragic, role of the Ottoman sultan on the operatic stage. This article explores Byron’s shifting engagement with Istanbul and Ottoman sovereignty in
The Bride of Abydos
and the Istanbul cantos of
Don Juan
alongside Mozart’s
Don Giovanni
and Rossini’s
Maometto II
. It departs from most studies of Byron’s orientalism by commenting on how the figure of the Ottoman sultan in his work complicates his response to both imperial cosmopolitanism and the emerging discourse of nationalism.
A ‘Romantic Land’ Twice Invaded, and Twice Supported: Byron, Hemans, Moore, and ‘Hafiz’ on Spain, 1808–14 and 1820–23
Authors: Blanco Agustín Coletes
Published: June 2020

Byron called Spain a ‘romantic land’ in
Childe Harold’s Pilgrimage
and in
The Age of Bronze
, thus repeating his support for the Spanish, who were facing major episodes of national crisis: first a Napoleonic, later, a Royalist, invasion. Byron was not alone. Other well-known contemporary writers, Felicia Hemans and Thomas Moore, and the less known yet influential Robert Stott (‘Hafiz’), had shown their support for Spain on both occasions. Was this an expression of these authors’ unabated trust in Spain, or of their sustained loyalty to their own convictions? Were they lending their support to
different
Spanish causes on each occasion? This article situates the analysis of these poets’ sympathy towards Spain within the historical and political shifts that divide the two instances of Byron’s use of ‘Romantic land’. The range of authors and texts presented here shows how the dramatic events in Spain during the Peninsular War and its aftermath, right up to the Congress of Verona, fascinated contemporary English poets.
Simultaneous Optical Transmission Spectroscopy of a Terrestrial, Habitable-zone Exoplanet with Two Ground-based Multiobject Spectrographs
Authors: Diamond-Lowe Hannah , Berta-Thompson Zachory , Charbonneau David , Dittmann Jason , Kempton Eliza M.-R.
Published: June 2020

Investigating the atmospheres of rocky exoplanets is key to performing comparative planetology between these worlds and the terrestrial planets that reside in the inner solar system. Terrestrial exoplanet atmospheres exhibit weak signals, and attempting to detect them pushes at the boundaries of what is possible for current instrumentation. We focus on the habitable-zone terrestrial exoplanet LHS 1140b. Given its 25-day orbital period and 2 hr transit duration, capturing transits of LHS 1140b is challenging. We observed two transits of this object, approximately 1 yr apart, which yielded four data sets thanks to our simultaneous use of the IMACS and LDSS3C multiobject spectrographs mounted on the twin Magellan telescopes at Las Campanas Observatory. We present a jointly fit white light curve, as well as jointly fit 20 nm wavelength-binned light curves from which we construct a transmission spectrum. Binning the joint white light-curve residuals to 3-minute time bins gives an rms of 145 ppm; binning down to 10-minute time bins gives an rms of 77 ppm. Our median uncertainty in

in the 20 nm wavelength bins is 260 ppm, and we achieve an average precision of 1.3× the photon noise when fitting the wavelength-binned light curves with a Gaussian process regression. Our precision on

is a factor of four larger than the feature amplitudes of a clear, hydrogen-dominated atmosphere, meaning that we are not able to test realistic models of LHS 1140b’s atmosphere. The techniques and caveats presented here are applicable to the growing sample of terrestrial worlds in the Transiting Exoplanet Survey Satellite era, as well as to the upcoming generation of ground-based giant segmented mirror telescopes.
Constraints on the Distances and Timescales of Solid Migration in the Early Solar System from Meteorite Magnetism
Authors: Bryson James F. J. , Weiss Benjamin P. , Biersteker John B. , King Ashley J. , Russell Sara S.
Published: June 2020

The migrations of solid objects throughout the solar system are thought to have played key roles in disk evolution and planet formation. However, our understanding of these migrations is limited by a lack of quantitative constraints on their timings and distances recovered from laboratory measurements of meteorites. The protoplanetary disk supported a magnetic field that decreased in intensity with heliocentric distance. As such, the formation distances of the parent asteroids of ancient meteorites can potentially be constrained by paleointensity measurements of these samples. Here, we find that the WIS 91600 ungrouped C2 chondrite experienced an ancient field intensity of 4.4 ± 2.8 μT. Combined with the thermal history of this meteorite, magnetohydrodynamical models suggest the disk field reached 4.4 μT at ∼9.8 au, indicating that the WIS 91600 parent body formed in the distal solar system. Because WIS 91600 likely came to Earth from the asteroid belt, our recovered formation distance argues that this body previously traveled from ∼10 au to 2–3 au, supporting the migration of asteroid-sized bodies throughout the solar system. WIS 91600 also contains chondrules, calcium-aluminum-rich inclusions and amoeboid olivine aggregates, indicating that some primitive millimeter-sized solids that formed in the innermost solar system migrated outward to ∼10 au within ∼3–4 Myr of solar system formation. Moreover, the oxygen isotopic compositions of proposed distal meteorites (WIS 91600, Tagish Lake and CI chondrites) argue that the CM, CO, and CR chondrites contain micrometer-scale dust and ice that originated in the distal solar system.
A Comparison of X-Ray Photon Indices among the Narrow- and Broad-line Seyfert 1 Galaxies
Authors: Ojha Vineet , Chand Hum , Dewangan Gulab Chand , Rakshit Suvendu
Published: June 2020

We present a detailed comparative systematic study using a sample of 221 narrow-line Seyfert 1 (NLSy1) galaxies in comparison to a redshift-matched sample of 154 broad-line Seyfert 1 (BLSy1) galaxies based on their observations using ROSAT and/or XMM-Newton in soft X-ray band (0.1–2.0 keV). A homogeneous analysis is carried out to estimate their soft X-ray photon indices (

) and its correlations with other parameters of nuclear activities such as Eddington ratios (R
Edd), bolometric luminosities (L
bol), black hole masses (M
BH), and the widths of the broad component of Hβ lines (FWHM(Hβ)). In our analysis, we found clear evidence of the difference in the

and R
Edd distributions among NLSy1 and BLSy1 galaxies, with steeper

and higher R
Edd for the former. Such a difference also exists in the spectral index distribution in hard X-ray (

), based on the analysis of 53 NLSy1 and 46 BLSy1 galaxies in the 2–10 keV energy band. The difference in R
Edd distributions does exist even after applying the average correction for the difference in the inclination angle of NLSy1 and BLSy1 galaxies. We also estimated R
Edd, based on SED fitting of 34 NLSy1 and 30 BLSy1 galaxies over the 0.3–10 keV energy band, and found that results are still consistent with R
Edd estimates based on the optical bolometric luminosity. Our analysis suggests that the higher R
Edd in NLSy1 is responsible for its steeper X-ray spectral slope compared to the BLSy1, consistent with the disk-corona model as proposed for the luminous AGNs.
Non-detection of M60-UCD1 in Quasi-simultaneous X-Ray and Radio Observations
Authors: Lena Davide , Rogantini Daniele , Miller-Jones James C. A. , Jonker Peter G.
Published: June 2020

Simultaneous detection in X-rays and radio, following the proportionality implied by the “fundamental plane of black hole activity,” can indicate the presence of an accreting black hole (BH), allowing a rough estimate of its mass. We used the XMM-Newton satellite and the Karl G. Jansky Very Large Array to perform quasi-simultaneous observations (within 24 hr) of the ultra-compact dwarf galaxy M60-UCD1, where the presence of a supermassive BH was inferred from stellar dynamics. The galaxy was not detected in either the X-ray or the radio band. We used the fundamental plane of BH activity to set constraints on the mass of any BH that might reside in its nucleus.

À l’heure où les cliniques psychiatriques ne se désemplissent pas, le rôle des gem est primordial, pour « l’avenir du handicap psychique » notamment, mais également pour les personnes avec des troubles du spectre autistique ou vieillissantes. En effet, les groupes d’entraide mutuelle permettent d’apporter un autre regard : vierge et non médical. Certes, la distinction entre soin et accompagnement n’est pas toujours clarifiée correctement auprès de tous, ce qui ne donne pas encore une entière légitimité aux bienfaits des gem . Il est vrai que pour le moment il n’y a pas assez de recul sur ces pratiques. Toutefois, Patrick Gohet, délégué interministériel aux Personnes handicapées, déclarait en 2004 dans une interview à Sport adapté magazine  : « Il est indispensable que, dans les structures de vie et de travail où il y a des activités d’accompagnement, les activités physiques et sportives trouvent toute leur place. » C’est pourquoi l’association sportive Actiphypsy vise un accompagnement exigeant des usagers des gem à partir d’une pratique raisonnée des activités physiques adaptées ( apa ) et accompagnés par des professionnels apa .

À travers un moment très particulier vécu lors d’un concert de jazz avec les résidents d’un foyer de vie, l’auteur questionne notre rapport au langage, à la beauté, à l’art. Il raconte comment la mise en liberté du langage peut être dérangeante mais aussi ouvrir tout un chacun à une autre considération de la différence.
La place et le rôle des familles en institution médico-sociale : impact de la dimension existentielle
Authors: Paillet Alice , Desport Mélanie
Published: June 2020

L’article présente les résultats d’une enquête associative sur le vécu et les représentations des professionnels sur la place et le rôle des familles en institution médico-sociale. L’objectif initial était d’identifier en quoi les familles étaient un facteur de stress pour ceux-ci. Les résultats révèlent que les difficultés relationnelles apparaissent dès qu’ils se trouvent confrontés aux mêmes limites concernant l’accompagnement des résidents, face à des questions existentielles telles que la sexualité et la mort, car il devient complexe de définir les rôles et places de chacun.
Les adjectifs tough et le marquage de l’infinitif en néerlandais
Authors: Lagae Véronique , Van Peteghem Marleen
Published: June 2020

En néerlandais, les adjectifs du type ‹difficile› ou ‹facile› entrent dans deux constructions qui se distinguent par la présence ou l’absence du complémenteur OM. L’objectif de cette étude est de montrer que ces deux constructions correspondent à deux analyses de la construction Tough proposées pour l’anglais et qu’elles donnent lieu à deux délimitations différentes de la classe des adjectifs tough . La construction appelée easy-to-please (avec OM) peut s’analyser comme une relative réduite, donc comme un ‹mouvement non A› alors que l’infinitif modal (sans OM) a les propriétés d’une structure à montée, donc de ‹mouvement A›. Nous montrons également que les adjectifs tough au sens strict, signifiant ‹difficile›, ‹facile›, ont une préférence nette pour la construction à infinitif modal, qui est donc la vraie construction Tough du néerlandais.
Circuits courts agro-alimentaires et clivages politiques : le cas des produits palmipèdes landais
Authors: Smith Andy
Published: June 2020

Depuis 15 ans, la recherche a produit des analyses fines des relations marchandes qu’implique l’agriculture en circuit court. Toutefois, le paradigme relationnel qui l’a dominée tend fortement à minimiser les conflits politiques qui marquent les industries agricoles concernées en les réduisant à des « jeux » qui ne sont que partiellement stabilisés. En s’appuyant sur une enquête portant sur l’industrie des produits palmipèdes, et guidé par l’institutionnalisme constructiviste, cet article restitue plus frontalement l’antagonisme structurel qui s’est développé autour des « circuits courts » dans les Landes, les deux objectifs socio-économiques contrastants qui leur sont attribués, et l’impact de ce clivage politique sur la régulation de la biosécurité, des labels et de l’installation des nouveaux entrants. Le texte dans son ensemble montre notamment que si les grippes aviaires de 2015-2016 semblaient initialement « rebattre les cartes » en faveur de la production en circuit court, dans cette industrie les institutions et les relations de pouvoir de longue durée ont rapidement contribué à restaurer une division du travail entre la production, la transformation et la commercialisation.
Operational planning of supply chains in a production and distribution center with just-in-time delivery
Authors: Biswas Pablo , Sarker Bhaba
Published: June 2020

Purpose: A supply chain consists of raw material suppliers, manufacturers and retailers where inventory of raw materials and finished goods are involved, respectively. Therefore, it is important to find optimal solutions, which are beneficial for both supplier, manufacturer and retailer.Design/methodology/approach: This research focuses on a semi-continuous manufacturing facility by assuming that the production of succeeding cycle starts immediately after the production of preceding cycle. In reality, the inventory of a supply chain system may not be completely empty. A number of products may be left over after the deliveries are made. These leftover inventories are added to the next shipment after the production of required amount to makeup a complete batch for shipment. Therefore, it is extremely important to search for an optimal strategies for these types production facilities where leftover finished goods inventory remains after the final shipment in a production cycle. Considering these scenarios, an inventory model is developed for an imperfect matching condition where some finished goods remains after the shipments.Findings: Based on the previous observation, this research also considers a single facility that follows JIT delivery and produces multiple products to satisfy customers’ demand. For this problem a rotational cycle model is developed to optimize the facility operations. Both problems are categorized as mixed integer non-linear programming problems which are to be solved to find optimum number of orders, shipments and rotational cycle policy for multiple products. Also, this solution will lead to estimate the optimum production quantity and minimum total system cost.Research limitations: This research considers the supply chain based on manufacturers point of view and it does not consider the transportation cost associated with supply chain. Next study will be focused on issues with joint decision making, information sharing, and transportation decision.Practical implications: This study will help the managers of refinery and paper industries in making their operation smooth by applying optimizing techniques and robust decision making.Originality/value: Based on the literature, no research was found on continuous production system supply chain and its optimization with JIT delivery. This research will definitely provide a direction for such problem to the researchers.
An adaptive edge finite element method for the Maxwell's equations in metamaterials
Authors: Wang Hao , Yang Wei , Huang Yunqing
Published: June 2020

In this paper, we study an adaptive edge finite element method for time-harmonic Maxwell's equations in metamaterials. A-posteriori error estimators based on the recovery type and residual type are proposed, respectively. Based on our a-posteriori error estimators, the adaptive edge finite element method is designed and applied to simulate the backward wave propagation, electromagnetic splitter, rotator, concentrator and cloak devices. Numerical examples are presented to illustrate the reliability and efficiency of the proposed a-posteriori error estimations for the adaptive method.

A Development of Augmented Reality Mobile Application to Promote the Traditional Indonesian Food
Authors: Weking Alfian Nara , Suyoto Suyoto , Santoso Albertus Joko
Published: June 2020

Traditional food is a representation of the culture and identity of certain regions and is a symbol of cultural heritage. Traditional Indonesian food must be preserved and introduced to the community, especially the easy generation as the next generation of the nation as a form of love for the culture that has been passed down from generation to generation. It aims to avoid the influence of food or foreign cuisine that enters Indonesia, which from time to time makes the preservation of traditional Indonesian food increasingly eroded. One form of an effective cultural approach is by introducing to the easy generation and also to the wider community. Therefore the use of technology is very important to maintain the preservation of traditional Indonesian food and convey it to the community, especially the easy generation. This study aims to develop a mobile application for augmented reality as a promotional medium to introduce traditional Indonesian food. Mobile augmented reality in applications built with the Unity3D program is done in different ways in presenting information to other media. This method allows users to view the media as a presentation of their information in the form of 2D and or 3D image modelling by using tracking images through a smartphone device's camera. The mobile augmented reality application that will be developed can provide an interesting and interactive information experience so that it can be fun for every user so that knowledge of traditional Indonesian food can be distributed and channelled so that the preservation of traditional Indonesian food is maintained.
Combination of Hiding and Encryption for Data Security

Published: June 2020

One of the techniques used in information security is the concealment technique, where the information to be hidden within another information medium to be saved in the process of messaging between two sides without detection. In this paper, an algorithm was proposed to conceal and encrypt data using several means.in order to ensure its preservation from detection and hackers. Wavelet transformer was used to change the shape of a wave of information (one and two-dimensional data) and its different mathematical formulas. Two sets of data were used, the first group used in a hidden process. The second group was considered as a means of both embedding and encryption.  The data in the second group is reduced to the extent of sufficient for the modulation process, by extracting its high-value properties and then removing them from the mother's information wave. The process of encrypting of the two sets of data comes together using an exponential function. The result is undetectable information signals. Algorithms were built to hide and encrypt one and two-dimensional data. High-security signals and images were obtained. Decryption algorithms were built to return encrypted data to their original forms, and getting the replica data.

Authors: Briciu Victor-Alexandru , Mircea Ioana-Alexandra , Briciu Arabela
Published: June 2020

The entrepreneurs need to create a good impression in order to act in the business environment. A bad impression affects the communication and implicitly the collaboration that can turn into unintended results. Thus, they access information on how to make a good impression by using several sources: specialty literature, training guides, and courses and online shows promoted by business sites. The main objectives of this chapter are to clarify the notions and the relations between communication and entrepreneurship in the Romanian context and also to present the main results of a research that aimed to identify if the first impression of a person in the Romanian business context is dissimulated or not. The implications for entrepreneurs consist in the degree of promotion of achieving a good first impression and the manipulative or persuasive value of the negotiation techniques applied in the Romanian business environment.
