The Chronology of two Bronze Issues in the Name of Philip II of Macedonia
Authors: Akamatis Nikos
Published: May 2022

Dans cet article, deux petites dénominations de bronze de Philippe II – les types Hercule / foudre (type A) et Hercule / massue (type B) – sont examinées sur la base de nouvelles données numismatiques et de découvertes archéologiques récentes en Grèce du nord. Les deux types monétaires ont été datés par la plupart des experts du règne de Philippe II (359-336 av. J.-C.). Bien que les deux types présentent certaines similarités, il faut exclure l’idée d’une frappe concomitante. Une des différences notable est la présence de symboles, de lettres et de monogrammes sur les monnaies du type B, en revanche absents sur celles du type A. On peut également relever d’autres différences en matière d’iconographie, de poids ou d’inscription. Une frappe des monnaies du type A au cours des premières années du règne du Philippe II semble être étayée par les découvertes archéologiques récentes, bien que celles-ci soient assez limitées. Au contraire, les monnaies du type B ont probablement été frappées de manière posthume, entre 325-309 ou 325-306 av. J.-C. Cette thèse est confirmée par l’étude des trésors ainsi que par la chronologie des tombes et autres contextes bien datés. En particulier, aucune tombe ne peut-être datée avant le dernier quart du ive siècle. Toutefois, les deux types monétaires, et principalement le type B, sont probablement restés en circulation jusqu’au début du deuxième quart du IIIe siècle av. J.-C.
Why do pirates and champions bite gold coins and medals?
Authors: Manas Arnaud
Published: May 2022

In this paper, I investigate whether it is true and to what extent pirates determined the fineness of gold coins by biting them. I use the classic beam theory to model coin bending. I bite five discs made of different gold alloys and conclude that while fine gold is softer than alloyed gold, pirates biting coins is almost certainly a Hollywood trope which finds its origin both in Stevenson’s Treasure Island and in the California gold rush of 1849.
A Cyborg Insect Reveals a Function of a Muscle in Free Flight
Authors: Vo-Doan T. Thang , Dung V. Than , Sato Hirotaka
Published: May 2022

While engineers put lots of effort, resources, and time in building insect scale micro aerial vehicles (MAVs) that fly like insects, insects themselves are the real masters of flight. What if we would use living insect as platform for MAV instead? Here, we reported a flight control via electrical stimulation of a flight muscle of an insect-computer hybrid robot, which is the interface of a mountable wireless backpack controller and a living beetle. The beetle uses indirect flight muscles to drive wing flapping and three major direct flight muscles (basalar, subalar, and third axilliary (3Ax) muscles) to control the kinematics of the wings for flight maneuver. While turning control was already achieved by stimulating basalar and 3Ax muscles, electrical stimulation of subalar muscles resulted in braking and elevation control in flight. We also demonstrated around 20 degrees of contralateral yaw and roll by stimulating individual subalar muscle. Stimulating both subalar muscles lead to an increase of 20 degrees in pitch and decelerate the flight by 1.5 m/s2as well as an induce in elevation of 2 m/s2.
Continuity Scaling: A Rigorous Framework for Detecting and Quantifying Causality Accurately
Authors: Ying Xiong , Leng Si-Yang , Ma Huan-Fei , Nie Qing , Lai Ying-Cheng , Lin Wei
Published: May 2022

Data-based detection and quantification of causation in complex, nonlinear dynamical systems is of paramount importance to science, engineering, and beyond. Inspired by the widely used methodology in recent years, the cross-map-based techniques, we develop a general framework to advance towards a comprehensive understanding of dynamical causal mechanisms, which is consistent with the natural interpretation of causality. In particular, instead of measuring the smoothness of the cross-map as conventionally implemented, we define causation through measuring the
scaling law
for the continuity of the investigated dynamical system directly. The uncovered scaling law enables accurate, reliable, and efficient detection of causation and assessment of its strength in general complex dynamical systems, outperforming those existing representative methods. The continuity scaling-based framework is rigorously established and demonstrated using datasets from model complex systems and the real world.

Organización actual de las guardias odontológicas: sus consecuencias en términos económicos y en la calidad de atención para una institución privada en la Ciudad Autónoma de Buenos Aires
Authors:   , Galán Julieta
Published: May 2022

La presente tesis de maestría aborda la temática de la salud bucal en tanto problema que integra múltiples y diversas preocupaciones por la salud pública. La salud bucal es fundamental para garantizar un bienestar general de la población total que va, desde la alimentación hasta ciertos hábitos y costumbres socialmente incorporadas. En este marco, destacamos que los eventos relacionados a la falta de un control de la salud bucal pueden tener profundas repercusiones en la salud general y en la calidad de vida de los ciudadanos. Es así como los efectos de las enfermedades bucodentales en términos de dolor, sufrimiento, deterioro funcional y disminución de la calidad de vida, son considerables y costosos. En términos generales y dentro de nuestro territorio nacional, al menos, se han instalados ciertos hábitos de control periódico de los niños menores de 6 años, así como controles preventivos en adultos con enfermedades crónicas. Sin embargo, todavía sigue quedando al margen, es decir, en segundo plano, la consulta odontológica programada como hábito preventivo. Frecuentemente, la consulta odontológica se ha realizado (y se realiza) en el momento que se presenta un cuadro de dolor agudo, traumatismo o urgencia estética. Esto significa que la mayoría de las personas que acuden a una consulta odontológica, recurren por una dolencia y/o patología, en lugar de atenderse por control. Por más que en otras especialidades médicas ya se habitúe las consultas año a año por control/prevención como el control anual oftalmológico, ginecológico en el caso de las mujeres, entre otras. Los motivos que se han encontrado acerca de estos hábitos, se podrían entender a partir de la falta de educación y promoción en materia de prevención odontológica, los altos costos que implica el tratamiento oral, desconocimiento en cuanto a coberturas, y a las dificultades de acceso a servicios. Por lo expuesto, se puede afirmar que más del 90 % de las consultas odontológicas se realizan en ocasión de una consulta espontánea de los pacientes ante un cuadro de emergencia. No existe, sin embargo, datos fidedignos a nivel regional, de cuál es el porcentaje de casos que se resuelven en guardia, ni cuáles son los factores condicionantes para que una consulta alcance su resolución en esta etapa. En consecuencia, nos proponemos determinar aquí qué sucede con la atención en las guardias odontológicas. Concretamente, nos interesa indagar la calidad de la atención Odontológica en la Guardia de la Clínica APO durante el año 2015. Para ello, recuperaremos una metodología interdisciplinar poniendo en diálogo aportes de múltiples disciplinas como la medicina, la economía, la sociología, la filosofía, la geografía, entre otras.
El manejo del ritmo en la poesía de Abraham Valdelomar
Authors: Ventura Vásquez Williams Nicks
Published: May 2022

Sobre la poesía de Abraham Valdelomar (1888-1919), la crítica especializada ha mencionado la autenticidad de incorporar la íntima añoranza familiar y la remembranza del paisaje regional; es decir, evocaciones que abrieron el sendero a la renovación literaria, luego de asimilar la tendencia poética modernista. Si bien se ha resaltado el tremendo valor que los aspectos rítmicos operan en la composición sonora de la poesía de Valdelomar, no se ha estudiado detenidamente el trabajo consciente del autor. En ese sentido, el presente artículo pretende vislumbrar la aplicación del ritmo en tres discursos poéticos (“El árbol del cementerio”, “Tristitia” y “Luna Park”) publicados en Las voces múltiples donde se evidencia el proceder rítmico en la composición versal. Para ello, utilizaremos los fundamentos teóricos del ritmo de cantidad y de intensidad propuestos por Balbín en Sistema de rítmica castellana y los principios de versificación de Navarro Tomás descritos en Métrica española.

Pengembangan Keterampilan Pembuatan Desain Kemasan Serta Pemanfaatan Pemasaran Digital Sebagai Strategi Bertahan UMKM yang Terdaftar Pada PLUT K-UMKM Kota Batu
Authors: Lia Della Ayu Zonna , Fitri Raisa
Published: May 2022

Tingginya tingkat persaingan antar pelaku UMKM di tengah era disrupsi digital dan menjamurnya e-commerce, mengharuskan pelaku UMKM memiliki keterampilan tambahan yang mampu memberikan nilai tambah pada produk yang mereka miliki. Pemberlakuan pembatasan pada kegiatan masyarakat dalam upaya penurunan penyebaran virus COVID-19, berdasarkan survei Kata Data Insight Center (KIC)  sebesar 82,9% UMKM terdampak negatif selama pandemi COVID 19.  Kondisi tersebut juga dikarenakan rendahnya pemanfaatan pemasaran digital, survei yang dilakukan Kata Data Insight Center (KIC)  membuktikan bahwa  hanya sekitar 4-10% UMKM memasarkan produknya pada platform digital. Upaya pemasaran digital ini juga harus disertai product branding yang baik, dimana hal tersebut diwujudkan dengan desain kemasan yang mewakili citra produk dan nilai tambah produk. Kedua strategi bertahan tersebut, diharapkan mampu diterapkan di Kota Batu yang memiliki total 14.750 unit UMKM, yang juga menjadi sumber pendapatan Kota Batu dan penyerap tenaga kerja. Menggunakan metode pelatihan dan pendampingan pada UMKM yang terdaftar di PLUT K-UMKM Kota Batu, diharapkan mampu memberikan solusi baru agar UMKM di Kota Batu mampu bertahan dan melakukan ekspansi pada masa pandemi COVID 19.

Potensi hasil perikanan di Kabupaten Selayar sangat berlimpah. Hal ini didukung karena merupakan wilayah kepulauan yang dikelilingi oleh pulau-pulau kecil dan berbatasan dengan perairan laut flores dan selat Makassar. Salah satu potensi hasil perikanan yang memiliki potensi untuk dikembangkan adalah ikan Cendro (Tylosorus sp). Pemanfaatan ikan ini belum terlalu dikembangkan. Namun dari segi ekonomi, ikan ini relatif murah dan cukup melimpah sehingga salah satu upaya untuk meningkatkan penggunaannya maka dibuat menjadi produk pangan. Selain dari segi ekonomis, kandungan nutrisi dari ikan ini cukup tinggi. Kandungan nutrisi meliputi protein, lemak, sedikit karbohidrat, vitamin dan garam-garam mineral. Salah satu pemanfaatan yang dilakukan adalah pembuatan kerupuk dan keripik ikan. Pada proses pembuatan maka perlu memperhatikan syarat-syarat yang di keluarkan oleh Badan POM, salah satunya adalah penambahan bahan pengawet pada produk pangan. Oleh karena itu, perlu juga diberikan pemahaman tentang bahan pengawet yang dizinkan oleh Badan POM.
Gondolatok a védelmi-biztonsági szabályozás reformjának egyes kérdéseiről
Authors: Kádár Pál
Published: May 2022

Az Országgyűlés 2020. őszi ülésszakán elfogadta az Alaptörvény kilencedik módosítását, amely a különleges jogrendre vonatkozó szabályrendszer alapjait 2023. július 1-jei hatállyal lényegesen megreformálja. Az alaptörvényi rendelkezés azonban csak az első lépése annak az átfogó jogalkotásnak és intézkedéssorozatnak, amely új alapokra helyezi a védelmi-biztonsági igazgatás egészét. A szerző áttekintést ad azokról a rendelkezésekről és jogalkotási lépésekről, amelyeken keresztül a védelmi-biztonsági szabályozás rendszere mélységében és működésében is megújul, és amelyek alapján a közigazgatás egésze felkészültebben nézhet szembe a 21. századi biztonsági kihívásokkal. A szabályozási reform következtében az ország védelmi képességei nem kizárólag a katonai vonatkozásban erősödnek, hanem a nemzeti ellenálló képesség megerősítésének követelményével összhangban komplexen, a teljes állami működésre kihatással fejleszthetők.
A proxyháborúk evolúciója
Authors: Ember István
Published: May 2022

A proxy-, vagyis a helyettesítők általi hadviselés komoly múlttal rendelkezik az emberiség történetében, és azt az egyes államok ma is magas színvonalon művelik. Rendkívül kedvező feltételeket biztosít azoknak a résztvevőknek, amelyek nem szeretnének közvetlen fegyveres konfliktusba kerülni egymással. A hidegháború időszakában a proxyhadviselést kizárólag a szuperhatalmak által alkalmazható módszernek gondolták a kutatók. E hadviselési forma napjainkban megváltozott körülmények mentén zajlik. A hibrid hadviselés jelentős hatást gyakorol a proxyháborúkra, emiatt szükségessé válik a korábban szilárdnak tartott alapvetések felülvizsgálata és aktualizálása. A hadviselési forma ismerete hozzásegítheti a kutatókat az egyes konfliktusok lefolyásának nagy pontossággal való előrejelzéséhez.
A Nemzetközösség múltja, jelene, jövője
Authors: Bajáki Péter
Published: May 2022

A Brit Nemzetközösség a világ egyik legrégebbi nem katonai-politikai államszövetsége, amelynek szerepe a közelmúltban bekövetkezett események hatására felértékelődött. Bár geopolitikai, geostratégiai szempontból pozíciója jelentős, katonai funkcióval a szervezet nem rendelkezik, ennek ellenére a tagországok összefogása és együttes nyomásgyakorlása adott helyzetben érvényesülhet. A Nemzetközösség – múltjából adódóan – erős brit befolyás alatt áll napjainkban is, működéséről, történetéről, gazdasági-társadalmi jelentőségéről azonban széles körben nem sokat hallani. A Covid–19 világjárvány okozta súlyos károkat szenvedett brit gazdaságnak mentőöv lehet egy olyan felvevőpiac, amelynek résztvevői szoros kapcsolatot ápolnak az országgal. Felvetődik a kérdés: a jelenlegi világgazdasági helyzetben az Egyesült Királyság élni tud-e a Nemzetközösség nyújtotta gazdasági lehetőségekkel, illetve sikerül-e újragondolnia a kapcsolati rendszereket a tagállamokkal?

„A városi környezetben vívott harcban a műveletek tervezése és végrehajtása során az ember építette környezet meghatározza azt az eszközrendszert, amely a vezető (parancsnok) rendelkezésére áll.” Ez a környezet gyorsan növekszik, és kölcsönhatásban más globális trendekkel a konfliktusok forrásává és műveleti környezetévé válik. Jelen tanulmányban a szerző igyekszik feltárni, hogy milyen folyamattal is állunk szemben, és ez milyen módon lehet hatással a katonai műveletekre.
Konvencionális légierőből aszimmetrikus haderőnem?
Authors: Lesták Tamás
Published: May 2022

Nagy-Britannia légi haderőneme az elmúlt évtizedekben szinte folyamatosan műveleti tapasztalatokat szerzett éles, harci körülmények között. Ezek a műveletek változó technikai és eljárásbeli kihívásokat jelentettek a szükséges képességek skáláján, a konvencionális jellegű képességektől az aszimmetrikus jellemzőkkel bírókig bezárólag. Jelen tanulmány a RAF által végrehajtott néhány fontosabb hadműveletet vizsgálja e szempontrendszer szerint, arra keresve a választ, hogy a brit légierő esetében mely képességek jelentették a prioritást az egyes hadműveletek során, illetve megállapítható-e egyértelmű fejlesztési irány ezen a téren.

Az autonóm fegyverrendszerekkel szemben támasztott követelmények a humanitárius nemzetközi jog tükrében
Authors: Schubert Bálint
Published: May 2022

Napjainkra a technológiai fejlődés egy olyan lépcsőfokára értünk el, amelyen egy autonóm fegyverrendszer (AWS) alkalmazásáról szóló beszámolót már nem nevezhetünk egyértelműen a tudományos fantasztikus irodalomból valónak. Az AWS-ek egyelőre nem jelentek meg széleskörűen még a legfejlettebb technológiákkal rendelkező államok fegyverarzenáljaiban sem, de prototípusai, különleges bevetésekre fejlesztett egyedi példányai már a világ legfejlettebb hadseregeinek rendelkezésére állnak. Példaként említhető az Észak- és Dél-Korea határára telepített SGR-A1 elnevezésű AWS.2 Az ilyen autonóm, működésüket tekintve emberi beavatkozástól és felügyelettől mentes fegyverrendszerek használata ugyanakkor számos jogi, morális és politikai kérdést vet fel. Ezek közül – természetükből adódóan, miszerint általában nemzetközi konfliktus vagy legalábbis nemzetközi jellegű konfliktusok során vetik be e rendszereket – kiemelkedő jelentőséggel bírnak a nemzetközi jog egy speciális normarendszerének, a jus in bello, vagyis a hadviselés joga szabályainak alkalmazása szempontjából. A szerző tanulmányában az autonóm fegyverrendszerek témáját körüljárva mutatja be azok nemzetközi jogi problémáit, például azt, hogy milyen előnyei és hátrányai vannak az ilyen fegyverek bevetésének, mely jelenlegi, a humanitárius nemzetközi jogot érintő szabályok vonatkoznak rájuk, illetve hogy hogyan felelnek meg ezek e szabályozás követelményeinek.

Conceptualization of Blockchain Enabled Interconnected Smart Microgrids
Authors: Dinesha Disha Lagadamane , Patil Balachandra
Published: May 2022

 Power systems are undergoing rapid transitions to incorporate renewable sources of generation and to combat climate change. Next stage of transitions will lead to a shift from large-scale, centralized systems to networks of smallsized, distributed electricity systems which require distributed or decentralized ledgers for database management for efficient transactions. Distributed Ledger Technology (DLT) are a form of decentralized ledgers where the transactions (energy, information and money) among various entities are maintained. One such DLT is blockchain technology which offers several advantages. Data recorded in blockchains are difficult to tamper with; have privacy protection; facilitate fast, accurate and real-time settlement of financial transactions. Contemporary research has started focusing on their possible applications in energy systems. State-of-the-art suggests that while business and market aspects have been extensively discussed, the electrical constraints and implementation methodologies have not been adequately addressed. Furthermore, all the reviewed projects have implemented only peer-to-peer transactions that are not scalable. To incorporate the new entities like prosumers, intermicrogrid transactions and interactions with the legacy power grid, new structural and operational frameworks are necessary. The proposed research explores the possibility of developing blockchain enabled smart microgrids (BSMG) with the above frameworks. It aims to build a conceptual framework of BSMG, including the transaction protocols and process flows. It proposes inclusion of network constraints in a three-levelled transaction setup which is executed over a four-layered architecture. Another practical challenge is that BSMGs may be set up on different blockchain platforms. Hence, this paper also proposes implementing Inter-Blockchain Protocol for the first time to include interoperability and communication between different platforms. Finally the performance metrics that will be used to validate the BSMGs are outlined.

Strongly enhanced self-phase modulation of femtosecond optical pulses in silicon nanowires with graphene oxide films
Authors: Moss David
Published: May 2022

We
experimentally demonstrate enhanced spectral broadening of femtosecond optical
pulses after propagation through silicon-on-insulator (SOI) nanowire waveguides
integrated with two-dimensional (2D) graphene oxide (GO) films. Owing to the
strong mode overlap between the SOI nanowires and the GO films with a high Kerr
nonlinearity, the self-phase modulation (SPM) process in the hybrid waveguides
is significantly enhanced, resulting in greatly improved spectral broadening of
the femtosecond optical pulses. A solution-based, transfer-free coating method
is used to integrate GO films onto the SOI nanowires with precise control of the
film thickness. Detailed SPM measurements using femtosecond optical pulses are
carried out, achieving a broadening factor of up to ~4.3 for a device with
0.4-mm-long, 2 layers of GO. By fitting the experimental results with theory,
we obtain an improvement in the waveguide nonlinear parameter by a factor of
~3.5 and the effective nonlinear figure of merit (FOM) by a factor of ~3.8,
relative to the uncoated waveguide. Finally, we discuss the influence of GO
film length on the spectral broadening and compare the nonlinear optical
performance of different integrated waveguides coated with GO films. These
results confirm the improved nonlinear optical performance for silicon devices
integrated with 2D GO films.
Towards Smart Public Interconnected Networks and Services – Approaching the Stumbling Blocks
Authors: Lønsethagen Håkon , Lange Stanislav , Zinner Thomas , Øverby Harald , Contreras Luis M. , Ciulli Nicola , Dotaro Emmanuel
Published: May 2022

The visions of 5G and Beyond (B5G) imply unprecedented expectations toward high-performing connectivity services in both public and private networks. Connectivity services that offer performance guarantees along multiple Quality of Service (QoS) dimensions are partially available today, but are confined to (virtual) private network services. However, open and equal access to public and Internet-scale Specialized Connectivity Services (SCS) delivered on-demand with interconnections across networks and support for mixed traffic modes that go beyond traditional best effort does not exist. In this paper, we argue that this is a huge industrial and societal problem that needs a solution. However, this problem is highly complex and multifaceted, and there are many reasons why we are more or less locked into the status quo.

The visions of 5G and beyond (B5G) imply unprecedented expectations toward general digital high-performing connectivity services in both public and private networks. Connectivity services that offer performance guarantees along multiple QoS dimensions are partially available today, but are confined to (virtual) private network services. However, open and equal access to public and Internet-scale Specialized Connectivity Services (SCS) delivered on-demand with interconnections across networks and support for mixed traffic modes that go beyond traditional best effort does not exist. In this paper, we argue that this is a huge industrial and societal problem that needs a solution. However, this problem is highly complex and multi-faceted, and there are many reasons why we are more or less locked into the status quo. This paper identifies the stumbling blocks and argues that there is a need for a holistic set of solution elements to take us across these hurdles. A roadmap approach is suggested alongside related research topics. Models and simulations are provided showing how a mixed traffic mode approach provides anticipated benefits. Arguments are given why the context brought by B5G will put us into conditions for change, allowing public SCS eventually at a global scale.
On the Predictive Power of Objective Intelligibility Metrics for the Subjective Performance of Deep Complex Convolutional Recurrent Speech Enhancement Networks

Speech enhancement (SE) systems aim to improve the quality and intelligibility of degraded speech signals obtained from far-field microphones. Subjective evaluation of the intelligibility performance of these SE systems is uncommon. Instead, objective intelligibility measures (OIMs) are generally used to predict subjective performance increases. Many recent deep learning based SE systems, are expected to improve the intelligibility of degraded speech as measured by OIMs.

However, validation of the OIMs for this purpose is lacking. Therefore, in this study, we evaluate the predictive performance of five popular OIMs. We compare the metrics' predictions with subjective results. For this purpose, we recruited 50 human listeners, and subjectively tested both single channel and multi-channel Deep Complex Convolutional Recurrent Network (DCCRN) based speech systems.

We find that none of the OIMs gave reliable predictions, and that all OIMs overestimated the intelligibility of `enhanced' speech signals.

In 2019 appeared a new Coronavirus Disease (COVID-19) in China, spreading rapidly globally and causing a pandemic with high infection and death numbers. To prevent a collapse of the health institutions, accurate decision making about assignments of intense care units (ICU) is required, depending on the probable outcome. The usage of machine learning (ML) for other medical fields had been successful before. So we applied ML techniques to a dataset of COVID-19 and influenza patients from Mexico to predict the severity of an individual’s infection regarding risk factors including, but not limited to, chronic obstructive pulmonary disease (COPD), cardiovascular disease, diabetes, asthma, immunosupression, and obesity. We conducted two experiments, one on hospitalised patients and the other one on a balanced dataset. The resulting applications should not be used as a diagnostic tool yet, due to a relatively short time period of data collection and 74.64% accuracy for the first experiment and 82.61% accuracy for the second one. Nonetheless it is a good starting point to continue research about predicting COVID-19 infection’s outcome based on risk factors.

Published: May 2022

Fused Deposition Modelling (FDM) or Fused Filament Fabrication (FFF) is an additive manufacturing technique in which layers of materials are fused together in a pattern to form an item. Acrylonitrile Butadiene Styrene (ABS), Poly Lactic Acid (PLA), Poly Ethylene Terephthalate (PET), Poly Vinyl Alcohol (PVA), Sandstone, and other materials are utilised in this FDM 3D printer. However, the rapid changes of Global needs and advances in Engineering domain, are in need of the combination of new materials to cater to fulfil the society and technical demands. Therefore, this work attempts to develop a new bio-composite filament for making components, which are associated with medical application. The commercially available extruders are not so cost effective and custom based for the biomaterials chosen for this work.
The selected materials for making the bio-composite are Poly Lactic Acid (PLA), Ultra High Molecular Weight Poly Ethylene (UHMWPE) along with Cissus quadrangularis (Adamant creeper) powder. So, it is essential to design and develop an extruder indigenously to make the Bio-composite filament. For this first phase, the basic components of the customized designed extruder are modelled using Solidworks 2018 and assembled. Subsequently the usage viability analysis is done by using ANSYS 18.1 at Manufacturing Engineering CAD laboratory. The thermal and dynamic analysis are successfully carried out. The results reveal that the heat sink of extruder could withstand up to 〖300〗^0 C and the heat transfer rates are reported.

Для определения понятия «информационная карта» осуществлен обзор основных этапов развития картографии в качестве инструментария, используемого для ориентации в окружающем пространстве, познания и планирования различных процессов, связанных с пространственными данными. С учетом данного обзора информационная карта определяется как цифровой объект, представляющий в пространстве исследуемое множество объектов, субъектов и процессов многомерного киберпространства на основе принципов: измеримости сходства объектов; близости изображений объектов, изображения контекста, воспроизводимости операций построения карты. Приводятся разноплановые примеры использования информационной карты в биологии, медицине, химии, социологии, интеллектуальном сотрудничестве и исторической науке. Тем самым обосновывается целесообразность информационного картографирования защищаемого киберпространства.

To define the concept of "information map", an overview of the main stages in the development of cartography as a tool used for orientation in the surrounding space, cognition and planning of various processes associated with spatial data is carried out. Taking into account this review, an information map is defined as a digital object representing in space the studied set of objects, subjects and processes of multidimensional cyberspace based on the principles: measurability of the similarity of objects; proximity of object images, context images, reproducibility of map building operations. Various examples of the use of the information card in biology, medicine, chemistry, sociology, intellectual cooperation and historical science are given. Thus, the expediency of information mapping of the protected cyberspace is substantiated.
