Low frequency noise in advanced Si bulk and SOI MOSFETs
Authors: Jomaah Jalal , Balestra Francis , Ghibaudo Gérard
Published: April 2024

A review of recent results concerning the low frequency noise in modern CMOS devices is given. The approaches such as the carrier number and the Hooge mobility fluctuations used for the analysis of the noise sources are presented and illustrated through experimental data obtained on advanced CMOS SOI and Si bulk generations. Furthermore, the impact on the electrical noise of the shrinking of CMOS devices in the deep submicron range is also shown. The main physical characteristics of random telegraph signals (RTS) observed in small area MOS transistors are reviewed. Experimental results obtained on 0.35-0.12 um CMOS technologies are used to predict the trends for the noise in future CMOS technologies, e.g., 0.1 um and beyond. For SOI MOSFETS, the main types of layout will be considered, that is floating body, DTMOS, and body-contact. Particular attention will be paid to the floating body effect that induces a kink-related excess noise, which superimposes a Lorentzian spectrum on the flicker noise.

Authors: Schwalke Udo
Published: April 2024

In this work we report on the process integration of crystalline praseodymium oxide (Pr2O3) high-k gate dielectric. Key process steps that are compatible with the high-k material have been developed and were applied for realisation of MOS structures. For the first time Pr2O3 has been integrated successfully in a conventional MOS process with n poly-silicon gate electrode. The electrical properties of Pr2O3 MOS capacitors are presented and discussed.
Mesh-free approach to Helmholtz equation based on radial basis functions
Authors: Kowalczyk Piotr , Mrozowski Michał
Published: April 2024

Recently, a radial basis functions (RBFs) method, which was originally proposed for interpolation problems, has been developed and applied to solve partial differential equations and eigenproblems. Properties of that method (meshfree algorithm) allows one to use it in many areas, including electromagnetics. In this paper the mesh-free RBF method for solving Helmholtz equation was applied and a new adaptive algorithm for defining the set of interpolation centers was proposed. Using the proposed approach the cutoff wavelengths and the field distribution in cylindrical waveguides of arbitrary cross-section were calculated with a high accuracy.
Absorption of EM energy by human body in the vicinity of the GSM base station antenna
Authors: Wójcik Dariusz , Topa Tomasz , Szczepański Krzysztof
Published: April 2024

A hybrid method is proposed for specific absorption rate analysis in a human body located in the near field of typical GSM base-station panel antenna. The method combines FDTD technique with analytical description of the near field of isolated antenna. The approximate results are found to be in excellent agreement with the results obtained by using the traditional FDTD. The most important advantage of proposed approach is minimization of computer memory requirements and

Improving interpretability: combined use of LVQ and ARTMAP in decision support
Authors: Kwok Hoi Fei , Giorgi Andrea , Raffone Antonino
Published: April 2024

The learning vector quantization (LVQ) network was used to classify the ECG ST segment into different morphological categories. Due to the lack of data in the ST elevation categories, the classifier was only trained to identify different types of ST depressions (horizontal, upsloping and downsloping). The accuracies were 91%, 85% and 65% respectively for the training, validation and testing data respectively. Despite the low accuracy for the testing data, most of the mis-classifications were downsloping ST depression being classified as horizontal ST depression. We concluded that more data and more training are needed in order to train the LVQ to recognize other morphological types of ST deviation and to improve the accuracy.
An adaptive iterative receiver for space-time coding MIMO systems
Authors: Teekapakvisit Chakree , Pham Van Dong , Vucetic Branka
Published: April 2024

An adaptive iterative receiver for layered space-time coded (LSTC) systems is proposed. The proposed receiver, based on a joint adaptive iterative detection and decoding algorithm, adaptively suppresses and cancels co-channel interference. The LMS algorithm and maximum a posteriori (MAP) algorithm are utilized in the receiver structure. A partially filtered gradient LMS (PFGLMS) algorithm is also applied to improve the convergence speed and tracking ability of the adaptive detector with a slight increase in complexity. The proposed receiver is analysed in a slow and fast Rayleigh fading channels in multiple input multiple output (MIMO) systems.
Application of convolutional interleavers in turbo codes with unequal error protection
Authors: Vaf Sina , Wysocki Tadeusz Antoni
Published: April 2024

This paper deals with an application of convolu- tional interleavers in unequal error protection (UEP) turbo codes. The constructed convolutional interleavers act as block interleavers by inserting a number of stuff bits into the interleaver memories at the end of each data block. Based on the properties of this interleaver, three different models of UEP turbo codes are suggested. Simulation results confirm that uti- lizing UEP can provide better protection for important parts of each data block, while significantly decreasing the number of stuff bits.

Choice With No Regret – Mobility Induced Migration in Fog Computing
Authors:   , Talebian Atefeh
Published: April 2024

Fog computing is a highly virtualized platform that acts as an intermediary be- tween end-devices and cloud centers. Due to the close proximity between fog nodes and users, fog computing is ideal for latency-sensitive applications. To ensure Quality of Service (QoS) for mobile users, especially in applications like autonomous vehicles, fog computing employs a network slicing approach for efficient resource allocation. Moreover, services need to be kept close to users, necessitating the transfer of services from current fog nodes to closer nodes while users are mobile, a process known as ”mobility induced migration in fog computing”.

This thesis introduces three novel methods: (1) Fuzzy Migration Decision (FMD)), (2) Efficient Destination Choice (EDC) and (3) Robust Intra-Slice Migration in Fog Computing. Each of these methods plays a distinct role in the migration process, encompassing the decision-making phase of when to initiate migration, the selection of the optimal destination node within the network, and the execution of migration in a manner that prioritizes robustness and low latency.

The FMD algorithm consistently outperforms existing methods by determining the optimal time to start migration using fuzzy logic. It achieves approximately a 15% reduction in migration time and a 12% decrease in network usage compared to bench- mark algorithms.

Similarly, the EDC algorithm, which aims to find the optimal destination node us- ing fuzzy logic and avoids negative impacts on network performance caused by mi- gration, achieves a 10.15% reduction in network usage compared to benchmark algo- rithms.

Moreover, our proposed Robust Intra-Slice Migration in Fog Computing algorithm demonstrates a reduction of total migration time by around 10-26% and downtime by about 2-23% compared to non-robust post-copy migration techniques.

The evaluation results demonstrate that the proposed algorithms effectively find a trade off between preserving QoS for users and enhancing network efficiency dur- ing their operation. Furthermore, when we execute the entire migration process using the proposed algorithms, there is a notable reduction in both migration latency and the number of migrations. This migration process exhibits robust performance when compared to other studies. These findings underscore how addressing all three mi- gration challenges (When, Where, and How) can significantly influence the overall outcome of mobility-induced migration.

Když dva dělají totéž: srovnávací tradiční rétorická analýza
Authors: Picha Marek
Published: April 2024

Text porovnává přesvědčovací strategie využité ve velmi podobných politicky angažovaných videoklipech The Great Schlep a Přemluv bábu. Ukazuje, že přestože se klip Přemluv bábu od své americké předlohy zásadně neliší v obecné struktuře, deklarovaném cíli či motivické výbavě, v jiných persvazivně významných ohledech se původnímu klipu vzdaluje. Rozdíly jsou patrné zejména v odlišné konstrukci publika, v jiném situování mluvčích a v topickém výběru vyjádřeném jinými stylistickými prostředky.
Reflexivita v propozičních postojích
Authors: Šmiřák Tomáš
Published: April 2024

Přijetí teze, že některé výrazy referují bez zprostředkování identifikujícími podmínkami přímo k objektům, vede k několika problematickým důsledkům týkajícím se propozičních postojů. Jedním z těchto důsledků je ten, že bychom tudíž na základě přesvědčení Lois Lanové, že Superman je silnější než Clark Kent, byli nuceni uznat, že je též přesvědčena o existenci někoho, kdo má tu vlastnost, že je silnější, než skutečně je. Snad žádný racionálně uvažující člověk by však zřejmě přesvědčení o existenci někoho, o kom by tato nemožná vlastnost měla platit, nepřijal. Klíčovým pojmem, na němž platnost vyvození tohoto přesvědčení stojí, je reflexivita – ze zjevně nereflexivního obsahu přesvědčení se vyvozuje přesvědčení reflexivní. Příspěvek se pokouší odhalit, kam je možno reflexivitu v rámci informačního obsahu věty zasadit. Zváženy jsou nejprve dvě možnosti: reflexivita je buď sémantickou vlastností vztahů, nebo anaforických zájmen. Obě možnosti budou vyvráceny prostřednictvím argumentace, že ve větách popisujících vztah mezi obsahy dvou koreferujících singulárních termínů nemůže být reflexivita součástí sémantické informace, jelikož znalost identity reference není podmínkou sémantické kompetence. Reflexivita je u těchto typů vět vázána na koordinaci znalostí mezi mluvčími. Jsou formulovány nutné podmínky, které by platnost daného vyvození teprve ospravedlnily.
Politickofilosofický úklid v čase plurality a zběsilé strnulosti
Authors: Géryk Jan
Published: April 2024

Autorský kolektiv z Katedry politologie brněnské Fakulty sociálních studií přichází s publikací, která má za cíl představit soudobé politicko-teoretické diskuze nad základními aspekty liberální demokracie, jako jsou například většinové rozhodování, idea lidské důstojnosti nebo vztah demokracie a lidských práv. Nepodává však pouze učebnicový přehled, ale jednotlivé představené koncepce též kriticky hodnotí. Jako problematické pak v obecnějším pohledu vnímá přílišné množství dílčích teoretických inovací spěchajících zachránit liberální demokracii. To totiž v konečném důsledku vede k nesrozumitelné kakofonii, která zevnitř disciplíny politické teorie/politické filosofie vychází. Kniha se tak snaží o systematizaci současných diskuzí a o pojmová vyjasnění. Jako zásadní věc pak vnímá též napětí mezi nutností přijímat legitimní a závazná kolektivní rozhodnutí a skutečností hluboké diverzity v současných společnostech. V poslední kapitole tak Pavel Dufek představuje jako vhodnou inspiraci teorie veřejného ospravedlnění. Tato recenze má za cíl seznámit čtenáře se základní strukturou a argumenty publikace a vnést do debaty s knihou některé další aspekty charakterizující naši postmoderní situaci.
Kauzalita činitele: představení hlavních argumentů knihy
Authors: Dvořák Petr
Published: April 2024

Článek shrnuje základní argumenty v knize P. Dvořáka Kauzalita činitele. Úvod do analytické diskuse o svobodě vůle (Togga 2020). Kniha obhajuje jednu dílčí teorii, tzv. kauzalitu činitele, coby nejlépe schopnou uchovat naše běžné intuice týkající se významu pojmu svoboda vůle a důsledků pro morální odpovědnost. V první části kniha uvádí základní pojmy a klíčový argument pro inkompatibilismus. Hlavního rivala, kompatibilismus v podobě tzv. standardní teorie (D. Davidson), odmítá ve třetí části. Hlavní teze, která leží v pozadí v obhajované hájené kauzality činitele, spočívá v tom, že kontingentní (sebe-)determinace představuje určitý střed mezi deterministickou a indeterministickou kauzalitou. Druhá část knihy pak hraje pomocnou úlohu: hájí nějaký typ dualismu (ať už vlastností či substanční dualismus) proti nereduktivnímu fyzikalismu tím, že se zaměřuje na tzv. problém vyloučení.
Časové vědomí a Husserlova kritika Brentana
Authors: Janoušek Hynek
Published: April 2024

Článek analyzuje původní verzi Husserlovy kritiky Brentanova pojetí časového vědomí, která je obsažena v Husserlových Přednáškách k fenomenologii vnitřního časového vědomí, a Husserlovu snahu vyřešit Brentanův argument nekonečně nekonečného regresu v rukopisném textu O primární modifikaci paměti. Z Husserlovy kritiky si všímá jen dvou bodů. Za prvé kritiky Brentanova prezentismu, tj. názoru, že časové vědomí je založeno v bodu přítomnosti, v němž jsou psychické fenomény, které názor času konstituují, dány současně. Za druhé Husserlovy výtky, že Brentano nepoužívá pro výklad vědomí času schéma počitkový obsah – pojetí počitkového obsahu. Za tímto účelem rekonstruuje text Brentanovu teorii v podobě, v které ji znal Husserl, a vykládá jak Brentanovy důvody pro odmítnutí časové povahy vnitřního vnímání, tak nedořešené problémy Brentanova hlediska. Následně se pokouší dokázat, že Husserl Brentanův prezentismus podcenil a že věcné problémy, které s jeho odmítnutím souvisely, musel řešit zavedením absolutně „kvazi-prezentního“ vědomí a odmítnutím schématu obsah – pojetí pro výklad konstituce imanentních časových jednot. Oba zvolené body Husserlovy kritiky Brentana se tak v pozdějších vrstvách přednášek ukazují jako částečně neoprávněné.The article discusses the original version of Husserl’s critique of Brentano’s concept of time consciousness, which forms a part of Husserl’s Lectures on the Phenomenology of the Consciousness of Internal Time. Next, it gives an overview of Husserl’s attempt to solve Brentano’s argument from the infinitely infinite regress against the consciousness of internal time. Two points of Husserl’s critique of Brentano are analyzed. The first point concerns Husserl’s critique of Brentano’s presentism. Brentano holds that consciousness of time is contained in the time point of the present now, in which psychical phenomena constituting our time consciousness are given simultaneously. The second point concerns the lack of content – apprehension scheme in Brentano’s explanation of the time consciousness. The article reconstructs Brentano’s position in the form known to Husserl and explains Brentano’s reasons for refusing the internal consciousness of time as well as problems connected with this refusal. An analysis of Husserl’s text proves that Husserl underestimated Brentano’s presentism and that he was forced to introduce a concept of the absolute time consciousness to solve the problems connected with his refusal of Brentano’s position. Since Husserl had to eventually give up the content – apprehension scheme in his explanation of immanent time unities, his original critique of Brentano is shown to be partly unjustified.
İ‘TİZÂLÎ DÜŞÜNCENİN ÂYETLERİN DİLSEL YORUMUNA ETKİSİ

Mu‘tezile İslam düşünce tarihinde önemli bir yeri olan aynı zamanda islâm ile ilgili itikadi prensipleri, aklî ilkeler çerçevesinde temellendirmeye çalışan kelâmi bir ekoldür. Mu‘tezile’nin ortaya çıkmasında fetihlerin akabinde farklı din ve kültürlere mensup insanlarla karşılaşılması ayrıca söz konusu fetihler neticesinde ilmi ve kültürel gelişmelerin artması önemli bir etken olmuştur. Mu‘tezile ekolü, itikadi alanda ortaya çıkmaya başlamasıyla birlikte kendine özgü inanç esasları ile ilgili ilkeleri oluşturmaya başlamıştır. Bu bağlamda usul-i hamse olarak ifade ettikleri “tevhid, adl, va‘d ve vaîd, el-menziletu beyne’l-menzileteyen ve emr bi’l-ma‘rûf nehyi ‘ani’l-münker” prensiplerini kendilerine ölçü edinmişler. İtikadi alandaki bütün düşünce ve meselelerini bu ilkeler çerçevesinde ifade etmeye çalışmışlardır. Buna ilaveten itikadi konularda Kur’ân’ın naslarına da aykırı bir düşünce ortaya koymamaya gayret etmişledir. Ancak bazen kendi ilkeleri ile Kur’ân naslarının çeliştiklerini görmüşlerdir. Dolayısıyla söz konusu nasları kendi itikadi ilkelerine uygun bir şekilde yorumlayabilmek için Arap dilinin imkânlarından yararlanmaya çalışmışlardır. Buna paralel olarak mu‘tezilî nahiv âlimleri de i‘tizalî düşüncelerine aykırı gördükleri ayetlerin zahiri anlamlarını dilin imkânlarından yararlanarak kendi itikadi düşüncelerine uygun olarak yorumlamışlardır. Bu çalışmada Arap dilinin tüm dilsel imkânları dâhil olmak üzere mu‘tezilî nahiv âlimlerinin Kur’an naslarını kendi itikadi ilkelerine göre yorumlamak için Arap dilinden nasıl istifade ettikleri konusu işlenmeye çalışılmıştır.
TUREYSİSÎ’NİN KUR’ÂN TE’VİLİNDEKİ İHTİLAF NEDENLERİNE VE MÜTEŞÂBİHE YAKLAŞIMI
Authors: Döner Naim
Published: April 2024

Mu‘tezilî bir âlim olan Rüknüddin Ebu Tahir et-Tureysisî’ye ilişkin Tabâkât kitaplarında herhangi bir bilgi bulunmamaktadır. Müellif, günümüze ulaşan Müteşâbihü’l-Kur’ân adlı eserinde inanç konularına dair âyetleri konulu bir şekilde kelâmî bir perspektifle değerlendirir. Haşviyye, Rafıza ve Batıniyye mezheplerinin Kur’ân te’viline yaklaşım yöntemlerini tenkit eden Tureysisî, aklī ve dilsel tahlil yöntemine dayalı Mu‘tezilî yaklaşım yöntemini savunur. Tureysisî’ye göre lafızdaki iştirak, iştikak ve icmal te’vilde ihtilafa neden olur. Bir karine bulunmadıkça lafzın hakikî manası bırakılıp mecazî manaya gidilmez. Hz. Peygamber’in söz ve fiilleri, beyana muhtaç olan namaz ve zekât gibi şer’î mücmellerin izah kaynağıdır. Atıf, mücaveret ve istisna gibi hususlar nazım cihetiyle, ziyadelik, hazif ve ifadenin yerinde kullanılmaması da mecaz açısından ihtilafın ortaya çıkmasına yol açar. Nassların bağlamından koparılması, birbiriyle ilgisi olmayan âyetlerin telfik edilmesi ve âyetlerin bütüncül olarak değerlendirilmemesi gibi hususlar da te’vilde ihtilafa sebep olur. Tureysisî’ye göre te’vilde anlamın doğruluğunu sağlayan temel ilkeler akıl, Kur’ân, Sünnet, İcma ve Arap dilidir. Doğru te’vili elde etmek için te’villerin bunlara arz edilmesi gerekir. Tureysisî, Allah Teâlâ‘nın müteşâbih âyetlere iman edenleri övmesi ve âyetlerin te’vilinin ardına düşenleri yermesi nedeniyle ilimde derin bilgi sahibi olanların da müteşâbihin anlamını bilmediği kanaatini taşımaktadır.

Time Electron Theory
Authors: Syed Munim Qadri
Published: April 2024

What is time? Is it a physical quantity, illusion, or dimension? Defining time is challenging and fascinating. We often consider time as a dimension to help us understand the concept of space-time. Time undeniably exists, but we can only sense its presence through its effects. For instance, if we take two apples, one bought months ago and the other just a day ago, we can tell that one apple was bought a long time ago because it had rotted. We express time as the effect caused by it. If there were no effects of time on this universe, then the concept of time would not exist [1,2].
Mathematics teacher specialization in elementary schools
Authors: Tawil Joumana , Dickson Brandon , Kotsopoulos Donna
Published: April 2024

This study explores elementary teacher and administrator perspectives related to mathematics specialty teachers in elementary schools, in a jurisdiction, where such roles were known by researchers to not be used. Mathematics specialty teachers are those teachers that have specialized training in both mathematics content and pedagogy. Online surveys were administered and completed by teachers and administrators in one school district in Ontario, Canada. The surveys included open- and closed-ended questions. The results of both the teacher and the administrator survey show that most participants were in favor of a mathematics teacher specialization model in elementary schools. Our findings contribute to the ongoing debate on the need for mathematics specialist teachers. While our findings are small and preliminary in nature, they represent a great interest amongst teachers and administrators on this school board in implementing such a model. These findings will have implications for policy makers both in the province of Ontario, but also in other regions looking to understand international models of mathematics education.

A doença cardíaca reumática (DCR) é endêmica em países em desenvolvimento.Os estudos com anticoagulantes de ação direta (direct-acting oral anticoagulants — DOAC) para a prevenção de eventos cardiovasculares em pacientes com fibrilação atrial (FA) associada a DCR têm sido limitados. O estudo INVICTUS avaliou dados de 4.531 pacientes com FA e DCR que apresentavam: escore CHA2DS2VASc≥2, área valvar mitral ≤2 cm2, e presença de contraste espontâneo ou trombo no átrio esquerdo. Os pacientes foram randomizados para receber rivaroxabana 20 ou 15 mg ou antagonista da vitamina K (AVK). O desfecho primário de eficácia foi um composto de acidente vascular cerebral, embolia sistêmica, infarto do miocárdio ou morte por causas vasculares (cardíacas ou não cardíacas) ou desconhecidas. O desfecho primário de segurança foi sangramento maior. A duração média de seguimento foi de 3,1±1,2 anos. A média de idade dos pacientes foi de 50,5 anos, e 72,3% eram mulheres. Na análise por intenção de tratar, o desfecho primário ocorreu em 560 pacientes (8,21%) no grupo rivaroxabana e 446 pacientes (6,5%) no grupo AVK (HR, 1,25; IC 95%, 1,1–1,4; P<0,001).

The impact of the military operation on the state of Ukraine’s economy is related to the growth of GDP in Ukraine in 2024 by 7.8%, the growth of inflation and national debt according to the consensus forecast of 10% and 90%, respectively. Therefore, attracting an investor to the business is one of the most important decisions, as it leads to increasing creditworthiness, risk distribution, incentive for innovation and infrastructure development. The main instruments of state regulation of investment activities include methods of financial planning, the economic-mathematical method, optimization of planned calculations, and the method of economic analysis. Within the framework of the above methods, we performed calculations for individual tasks to obtain the greatest profit from investing money; logistical issue of fast delivery of goods; optimal distribution of salespeople at retail outlets.Therefore, it is important to conduct simulations in the economy of Ukraine, even during the period of military operations, as this can contribute to the development of the country and increase its resilience to economic challenges.

Authors:   State Organisation “Institute for Economics and Forecastingof the National Academy of Sciences of Ukraine”, Tsyplitska Olena
Published: April 2024

The study focuses on the reassessment of the role of strategic planning of industrial development in conditions of global instability. It is determined that both developed and developing countries return to strategic planning due to various obstacles for industrial development in terms of high level of uncertainty, consequences of crisis and over-reliance on market forces. The known methodological approaches to strategic planning, in particular, the structure, internal and external environment analysis techniques, in the international space and in Ukraine are considered. Two main issues regarding conducting strategic planning processes in unstable environment are studied. The first is government intervention, which facing to global challenges, should expand the variety of industrial policy instruments through technological foresight and strategic diagnostics of the industry. The second relates to moving beyond the simple SWOT or PESTLE analysis in order to account global and local risks for the industrial sector. The types of industrial strategies and the criteria for their selection by a certain country are highlighted in the research. The ways to increase the state capacity to strategize industrial development and the determinants of strategic plan success are proposed.

Authors:   State Biotechnological University, Muzychenko Mykola
Published: April 2024

The historical development of China's gas market since the establishment of the People's Republic of China in 1949 to the present day has been investigated, particularly focusing on key stages of the gas industry's evolution. The transition of China from predominantly using coal to increasing consumption of natural gas, especially in the industrial sector, has been described. The stages of pipeline and liquefied natural gas (LNG) imports, as well as the pricing reform in the domestic market in 2011, have been extensively examined. The import of LNG by China, which began in the late 1990s to meet the country's significant gas demand, has been discussed along with the factors influencing this trend, including the impact of pandemic restrictions on demand. The development of LNG terminal infrastructure in China and planned future constructions and expansions, indicating a strategic approach to the country's gas sector, have been outlined. It has been noted that the liberalization of the Chinese gas market has led to the emergence of a new generation of LNG buyers, including regional government and municipal enterprises in the private sector. China's participation in global LNG projects, reflecting its active role in the gas industry, has been highlighted. The structure and dynamics of pipeline gas imports into China have been investigated. The network of pipelines connecting gas fields in Turkmenistan to China, including trunk lines A, B, and C, as well as the under-construction line D, has been analysed. The dynamics of natural gas production and consumption in China from 1990 to 2020 have been examined. The rapid growth in natural gas consumption in the country since 2010 has been noted. The sectoral and regional specificity of gas consumption, where industry uses it as both raw material and fuel in the highest quantity (52.3%), has been analysed. Demand for natural gas in China is forecasted to increase until 2035, but domestic production and re-export may influence conditions in the global LNG market after 2025.

A statistical analysis of the financial provision for inclusive development of territorial communities in the conditions of martial law has been conducted. It has been established that there is a significant increase in the revenues of local budgets in the Zakarpattia region and its communities, primarily due to the influx of a considerable population from other regions to the region, as well as increased business activity resulting from the relocation of enterprises from the east. The emergence of new challenges of inclusive orientation in the conditions of war has been demonstrated, namely: the need to ensure decent living conditions for citizens who are temporarily displaced persons from other regions, increased workload on local preschools and secondary educational institutions, and increased burden on healthcare systems. It has been proven that addressing the issues of financial provision for programs of inclusive development of territorial units will require coordinated efforts of government authorities and local self-government at all levels in the sphere of budget accumulation and effective redistribution. In this regard, it is important to create conditions for additional mobilization of funds by territorial communities for financing programs of inclusive growth.

Published: April 2024

The sectoral analysis of the of Ukrainian industry in general and the machine-building sector in particular, conducted by the author for the period from 2010 to the present, revealed threatening trends in the number of machine-building companies with domestic capital in favour of small and medium-sized enterprises with foreign capital that proves Ukrainian export potential reduction in the foreign market of machine-building products and the necessity to support export-oriented companies at the state level.Segmental assessment of the machine-building complex of Ukraine on the basis of the index approach, conducted by the author for the period from 2011 to the present, revealed the presence of strategic potential reserves for such machine building segments as production of vehicles, trailers and other vehicles and machinery and equipment production and other groups in 2019 and the production of electrical equipment, computers, electronic and optical products in 2020. The results of the segmental assessment of mechanical engineering in Ukraine indicate the need of programs development to strategize the development of potentially successful segments and investment support for unprofitable segments in order to prevent their decline.

Las pegmatitas de Mina Santa Elena (El Quemado, Salta, Argentina) pertenecen a la familia LCT, clase de elementos raros, tipo berilo, subtipo berilo-columbita-fosfato.La paragénesis de estadio pegmatítico incluye fosfatos de Li-Al-F-OH (montebrasita), Li-Mn-Fe (litiofilita), Ca-Mn-Fe-OH (jahnsita?), Ca-F-OH-Cl (apatita), Mn-Fe-Mg-Ca (triplita) y Al-Fe-Mg-OH (scorzalita); óxidos de Nb-Ta (columbita-tantalita), U (uraninita) y Zn (gahnita); silicatos de Li (Li-muscovita, lepidolita, elbaíta, espodumeno); y otros silicatos no litíferos tales como zircón, berilo, muscovita, chorlo,granate, feldespatos (albita, microclino) y cuarzo. La montebrasita contiene F entre <1% y 2,3%, y Li2O de 7,47-9,86%. El fundido, enriquecido en P, F y H2O, promovióla cristalización de montebrasita más que espodumeno, a temperaturas inferiores a los 400°C. Las fases minerales en paragénesis compitieron por diversos elementos químicos, de los cuales el F fue consumido preferencialmente por las micas y el Mn por columbita-tantalita. La removilización de Li, Ca, Mn y Fe durante el estadio hidrotermal contribuyó al desarrollo de venillas de triplita, apatita, litiofilita y souzalita, y al emplazamiento de una zona de reemplazo con lepidolita. Se interpreta que el incremento de la actividad del F constituyó un mecanismo efectivo en el fraccionamiento de Fe-Mn en la serie columbita-tantalita.

In the management of service stations in the city of N’Djamena and in the concern to resolve their storage management, and their taming from the Djarmaya refinery. We used GIS and metrology measurements in this perspective in order to verify the quantities of petroleum products supplied to the population of N'Djamena. Thanks to this approach, we were able to check more than 146 gas stations in the city of N'Djamena. It was observed that the association of service stations and their GPS coordinates allowed us to determine which are the most efficient stations for the delivery of petroleum products to N’Djamena. The implementation of this methodology played a crucial role in the efficient management of travel and fuel operations. By employing the 2819 gauge, which has exceptional accuracy and reliability, it has played a vital role in establishing high quality standards in different industrial fields where metrology is crucial to ensure the accuracy and reliability of final products. By pairing the 2819 gauge with GPS, nearby fuel stations can be easily located, simplifying planning routes and refueling stops, which can help make informed decisions when driving. Involves choosing a station to refuel. By incorporating GPS into the management of gas stations in the city of N'Djamena, it is possible to optimize the efficiency of operations, customer satisfaction and the overall management of the fuel distribution network.
