Authors: Smolin M. B.
Published: April 2024

The article is devoted to the concept of power of the professor of the Imperial Novorossiysk University Pyotr Evgenievich Kazansky (1866–1947), described in the capital study “The Power of the All-Russian Emperor. Essays on the Current Russian Law” (Odessa, 1913).

This study was devoted to the supreme power, which, under any political principle, always exists alone in the state. The study deals with the supreme state power, its manifestations in various areas of public administration during the Duma monarchy. The book is devoted to the tradition of Russian state power, the clarification of its historical place in society and the state and its power activities. Professor P.E. Kazansky claims that the emperor possessed not only executive, legislative or judicial power, but also the Supreme Power of the Empire, which directed the activities of all subordinate departments.
Waste water treatment through microalgae and cyanobacteria
Authors: Rajput Ritu Singh , Kumar Anuj
Published: April 2024

Resource recovery systems for microalgae and cyanobacteria could substantially advance the recovery of nutrients from waste water by reaching the rate of effluent nitrogen (N) and phosphorus (P) below the current technology limits. However, the efficient introduction of phytoplankton involves the creation of process models that retain efficiency and simplicity in order to effectively replicate complex performance in response to environmental conditions. This research synthesises the variety of model structures that have gained from the modelling of algae and cyanobacteria and the key model features needed to allow reliable process modelling in water resource recovery facilities. Processes of cyanobacteria, including comprehensive growth prediction guidelines (under phototrophic, heterotrophic and mixotrophic conditions), nutrient absorption, carbon absorption and accumulation, and respiration are provided.

Additional Legal Protection for Corruption Whistleblowers
Authors: Fardiansyah Ahmad Irzal , Farid Muhammad , Diansyah P Ramadani Fitra
Published: April 2024

Corruption represents a breach of the economic rights of society, elevating it beyond mere criminality to the status of an extraordinary offense. Therefore, safeguarding the rights of individuals who report instances of corruption is necessary to ensure their protection. As law enforcement officers, Prosecutors hold the authority to provide legal protection to whistleblowers of corruption, as stipulated in Law Number 13 of 2006 concerning the Protection of Witnesses and Victims (LPSK). Among the various legal protections provided to whistleblowers, maintaining the confidentiality of their identity stands out as the utmost priority. This protection is crucial to ensure effective law enforcement. Hence, safeguarding whistleblowers is important, and to formalize this, law enforcement should be empowered to provide them with the necessary protection.

Unprecedented selectivity for homologous lectin targets: differential targeting of the viral receptors L-SIGN and DC-SIGN

Published: April 2024

DC-SIGN (CD209) and L-SIGN (CD209L) are two C-type lectin receptors (CLRs) that facilitate SARS-CoV-2 infections as viral co-receptors. SARS-CoV-2 manipulates both DC-SIGN and L-SIGN for enhanced infection, leading to interest in developing receptor antagonists. Despite their structural similarity (82% sequence identity), they function differently. DC-SIGN, found in dendritic cells, shapes the immune response by recognizing pathogen-associated carbohydrate patterns. In contrast, L-SIGN, expressed in airway epithelial endothelial cells, is not directly involved in immunity. COVID-19’s primary threat is the hyperactivation of the immune system, potentially reinforced if DC-SIGN engages with exogenous ligands. Therefore, L-SIGN, co-localized with ACE2-expressing cells in the respiratory tract, is a more suitable target for anti-adhesion therapy. However, designing a selective ligand for L-SIGN is challenging due to the high sequence identity of the Carbohydrate Recognition Domains (CRDs) of the two lectins. We here present Man84, a mannose ring modified with a methylene guanidine triazole at position 2. It binds L-SIGN with a KD of 12.7 μM ± 1 μM (ITC) and is the first known L-SIGN selective ligand, showing 50-fold selectivity over DC-SIGN (SPR). The X-ray structure of the L-SIGN CRD/Man84 complex reveals the guanidinium group’s role in achieving steric and electrostatic complementarity with L-SIGN. This allows us to trace the source of selectivity to a single amino acid difference between the two CRDs. NMR analysis confirms the binding mode in solution, highlighting Man84’s conformational selection upon complex formation. Dimeric versions of Man84 achieve additional selectivity and avidity in the low nanomolar range. These compounds selectively inhibit L-SIGN dependent trans-infection by SARS-CoV-2 and Ebola virus. Man84 and its dimeric constructs display the best affinity and avidity reported to date for low-valency glycomimetics targeting CLRs. They are promising tools for competing with SARS-CoV-2 anchoring in the respiratory tract and have potential for other medical applications.
Modulators of the Hop-HSP90 Protein-Protein Interaction Disrupt Early-Stage of KSHV Lytic Replication
Authors: Veale Clinton , Okpara Michael , Vaaltyn Michaelone , Mahama Alhassan , Albericio Fernando , de la Torre Beatriz , Clarke David , Edkins Adrienne
Published: April 2024

The central role of the chaperome in maintaining cellular proteostasis has seen numerous viral families evolve to parasitically exploit host chaperones in their life cycle. The HSP90 chaperone protein and its co-chaperone Hop, have both individually been shown to be essential factors for KSHV lytic replication. Given the fundamental regulatory role that PPIs play in cellular biology, we reasoned that disrupting the Hop-HSP90 PPI may provide a new host-based target for inhibiting KSHV lytic replication. This study expands upon a previous report of non-natural peptides, which disrupted the association between the HopTPR2A and its interacting HSP90CTD. Here, in addition to demonstrating disruption of the full-length Hop-HSP90PPI, and selective engagement with the HopTPR2A domain in cell lysates, we showed that a cell-penetrating peptide modified analogue, inhibited intracellular HSP90 and acted as a non-cytotoxic inhibitor of early-stage KSHV lytic replication. Importantly, this activity resulted from inhibition of specific KSHV lytic genes, rather than a global reduction in viral DNA transcription. In addition to tentative evidence for the Hop-HSP90 PPI as a much-needed target for KSHV drug discovery, this study represents an important step in understanding host HSP90 – viral interactions.
Investigation of key electronic states in layered mixed chalcogenides with a d0 transition metal as Li-ion cathodes
Authors: Kumar Khagesh , Sunariwal Neelam , Louis Jacques , Leube Bernhard , Roy Indrani , Sterbinsky George , Tarascon Jean-Marie , Cabana Jordi
Published: April 2024

Lithium-rich transition metal chalogenides are witnessing a revival as candidates for Li-ion cathode materials, spurred by the boost in their capacities from transcending conventional redox processes based on cationic states and tapping into additional chalcogenide states. A particularly striking case is Li(2)TiS(3-y)Se(y), which feature a d0 metal. While the end members are expectedly inactive, substantial capacities are measured when both Se and S are present. Using X-ray absorption spectroscopy, we confirm that, in Li(2)TiS(2.4)Se(0.6), this behavior is underpinned by concurrent and reversible redox of only S and Se, and identify key electronic states. Moreover, wavelet transforms of the extended X-ray absorption fine structure provide direct evidence of the formation of short Se-Se units upon charging. The study uncovers the underpinnings of this intriguing reactivity and highlights the richness of redox chemistry in complex solids.
Buildup and Consumption of Species in Emulsion Droplets during Aqueous Suzuki Coupling Correlate with Yield
Authors: Peacock Hannah , Blum Suzanne
Published: April 2024

Fluorescence lifetime imaging microscopy (FLIM) provides spatiotemporal resolution of the changing composition of emulsion droplets during an aqueous–surfactant Suzuki coupling. In contrast to previous investigations, the present experiments characterize the full course of a catalytic chemical reaction, addressing key questions about if and where reaction species build up, and correlating these microscale behaviors with bench-scale product yields. At low concentrations of (active) catalyst, droplet environments are stable; however, at higher concentrations, emulsion droplet environments change markedly, as indi-cated by the rise and fall of fluorescence lifetimes. These changes are consistent with buildup and consumption of reaction species inside the droplets. A combination of FLIM and brightfield imaging pinpoint limitations in catalyst solubility as controlling the rate and degree of buildup of species in droplets. These solubility limitations are also identified as the cause of a reaction induction period, and an origin of the rate-and-reproducibility advantage obtained by adding a THF as a cosolvent. The subsequent mechanistic model from these data led to a bench-scale reaction optimization, wherein premixing the catalyst components bypasses the catalyst induction period, resulting in a faster reaction at otherwise constant catalyst load-ing. The understanding generated by FLIM thus provides an early example of how understanding changes in droplet compo-sitions on the microscale during ongoing aqueous–organic reactions can be leveraged for enhancing efficiencies in bench-scale reactions.

Hysteresis and Bistability Bifurcation Induced by Combined Fluid Shear Thickening and Double-Diffusive Convection in Shallow Porous Enclosures Filled with Non-Newtonian Power-Law Fluids
Authors: Khir Saleh , Rebhi Redha , Kezrane Mohamed , Borjini Mohamed Naceur
Published: April 2024

This paper presents a numerical study of the linear and non-linear stability of thermosolutal convection within a porous medium saturated by a non-Newtonian binary fluid. The power-law model is utilized for modeling the behavior of the working medium. The given statement implies that the horizontal boundaries experience thermal and solutal flow rates, whereas the vertical walls are impermeable and thermally isolated. The relevant factors that govern the problem being investigated are the Rayleigh number, , the power-law index, , the cavity aspect ratio, , the Lewis number, , and the buoyancy ratio, . An analytical solution is obtained for shallow enclosures ( ) using the parallel flow approximation and a modified form of the Darcy equation. By solving the entire set of governing equations, a numerical investigation of the same phenomenon was conducted. One of the most intriguing discoveries from this research is that it identifies a bi-stability phenomenon, this particular phenomenon signifies the existence of two stable solutions. The results obtained from both methods demonstrate a good level of agreement across a diverse range of these governing parameters.

Published: April 2024

This study explores the growth of Sb2Se3 films on soda-lime glass (SLG) surfaces using the chemical molecular beam deposition (CMPD) method at a substrate temperature of 500°C. High-purity binary compounds, Sb2Se3 and Se, were employed as source materials for film deposition. Scanning electron microscopy (SEM) was employed to investigate the morphological characteristics of the Sb2Se3 films. Furthermore, the influence of temperature on the grain size and crystallographic orientation in selenium films was examined. Samples were obtained from a selenium source at temperatures of 370°C and 430°C. The results indicate that increasing the temperature of the selenium source results in the formation of larger grains and the presence of rod-shaped grains of Sb2Se3 aligned parallel to the substrate. A sample obtained at 370°C exhibited grains larger than 2 µm in size, evenly distributed across the substrate surface, indicating a uniform growth process. In contrast, when the temperature of the selenium source was raised to 430°C, considerably larger grains measuring approximately 4 μm were detected on the film surface substrate. X-ray diffraction analysis was conducted to gain insights into the crystalline phases and crystal structure of the Sb2Se3 films synthesized under different temperatures of the selenium source. The X-ray diffraction patterns displayed prominent peaks corresponding to the crystallographic planes (221) and (211), indicating the presence of strong crystalline phases. Additionally, peaks such as (020), (120), and (310) were observed in the X-ray patterns, further confirming the crystallinity of the films.

Authors: Das Trishna Moni , Sarmah Devabrata , Borah Sankar Moni , Baruah Sunandan
Published: April 2024

In this work the evolution of a capacitive type sensor based on nanoporous anodic aluminum oxide (AAO) fabricated by a two-step anodization process using a low-cost customized setup designed in-house is reported. The parallel plate capacitors were fabricated using aluminum (Al) as base electrode and gold as top electrode, where the porous AAO was used as the dielectric material. This demonstrated the clear dependence of the capacitance values of the as prepared different sensors on the dielectric material’s thickness. The as developed sensors were tested for the detection of arsenic (As) ions.An increase in the capacitance was observed while increasing the concentration of the As ion in aqueous solutions. The presence of As ion was confirmed through EDS (Energy dispersive X-ray spectroscopy) mapping carried out in a FESEM. This change in capacitance can be attributed to the change in dielectric constant of the active material with the incorporation of metal ions.

Isothermal Decay Analysis of Thermoluminescence Peaks of Quartz for Kinetic Parameter Determination
Authors: Mammadov Sahib , Gurbanov Muslim , Abishov Aqshin , Ahadov Ahmad
Published: April 2024

This study delves into the intricacies of isothermal decay analysis applied to thermoluminescence (TL) peaks, focusing on determining kinetic parameters. The study challenges the conformity of the trap responsible for the ITL signals to first, second, or general-order kinetics, supported by the non-conforming decay pattern and the inference of two overlapping first-order TL peaks. This work enhances the understanding of TL peaks and establishes a reliable methodology for characterizing luminescence mechanisms in materials, contributing to advancements in luminescence dosimetry research. These observations lead to the conclusion that the TL data originates from more than one trap, and based on existing literature, it is inferred that there are two overlapping first-order TL peaks. The investigation involves the consideration of isothermal decay data at distinct temperatures (T = 250, 260, 270, 280, and 290°C) and explores challenges associated with achieving precise linear fits for different kinetic order values (b). The nature of decay is interpreted based on the monomolecular theory, suggesting adherence to a first-order process. ITL curves were deconvoluted into two exponential decay curves. The slopes of the regression lines provide activation energy (E) values for curve1 and curve2, respectively: E1 = 0.99±0.16 eV and E2 = 1.32±0.18 eV. The frequency factor (s) is determined from the intercept of the regression line: s1 = 1.32×108 s−1 and s2 = 1.77×1012 s−1.

Authors: Zhytniakivska Olga , Tarabara Uliana , Vus Kateryna , Trusova Valeriya , Gorbenko Galyna
Published: April 2024

Protein-based drug nanocarriers are increasingly recognized as promising candidates for effective drug delivery, owing to a multitude of beneficial advantages over synthetic materials including low cytotoxicity, biocompatibility, biodegradability, abundance, renewability, and high drug loading capacity mediated by diverse functional groups and interactions. In the present study the molecular dynamics simulation was employed to explore the stability of lysozyme-based drug delivery nanosystems functionalized by the antiviral drugs (favipiravir, molnupiravir, nirmatrelvir and ritonavir) and cyanine dyes (AK7-5, AK5-6, AK3-11). A series of 5 ns or 100 ns MD simulations for the top-scored docked drug-dye-protein complexes, obtained using the PatchDock server was performed at 310 K with GROMACS software using the CHARMM General Force Field. The MD results have been analyzed in terms of the parameters, such as the backbone root mean-square deviation, gyration radius, solvent accessible surface area, the root means square fluctuations. The analysis of calculated parameters for the studied systems enabled us to improve the previously acquired molecular docking data. Taken together, the results obtained indicate that Lz-F-AK3-11, Lz-R-AK75, Lz-R-AK56, Lz-N-AK75, Lz-N-AK3-11, and Lz-M-AK75 systems exhibit the highest stability among the examined dye-drug-protein systems and represent potential candidates for the targeted delivery of the explored antiviral agents.
Characteristics of Nonlinear Dust Acoustic Waves (DAWs) Propagating in an Inhomogeneous Collisionless Magnetized Dusty Plasma
Authors: Hirak Jyoti Dehingia  , Deka Paramananda
Published: April 2024

In this paper, we have presented our investigation on the characteristics of nonlinear dust acoustic waves (DAWs) propagating in an inhomogeneous collisionless magnetized dusty plasma (MDP). In this problem, we have considered a collisionless plasma consisting of nonthermal ions, non-extensive electrons and negatively charged dust grains. Using the reductive perturbation theory (RPT) we have derived the modified Zakharov-Kuznetsov (m-ZK) equation. The solution of m-ZK equation indicates the nonlinear characteristics of the DASWs in plasma. Our investigation also predicts how the amplitudes of nonlinear DASWs are significantly modified due to the influence of magnetic field, non-extensive electrons and inhomogeneity parameters in plasma. The results obtained in this investigation may be useful for understanding the propagation characteristics and modification of structures of nonlinear waves in both laboratory and astrophysical plasmas.
Decision support for extracting and dissolving consumers’ uneasiness over foods using stochastic DEMATEL
Authors: Tamura Hiroyuki , Okanishi Hiroki , Akazawa Katsuhiro
Published: April 2024

In this paper we try to extract consumers’ uneasy factors on foods such as carcinogenic substance, bovine spongiform encephalopathy (BSE) problem, genetic recombination, etc., and try to construct structural models among these uneasy factors using stochastic DEMATEL. Stochastic DEMATEL is developed as a revised DEMATEL (Decision Making Trial and Evaluation Laboratory) to extract structural models of a complex problematique composed of many factors under uncertainty. For structural modeling of uneasy factors on foods we look at the binary relation such that “How much would it help to dissolve uneasy factor j by dissolving uneasy factor i?” Finally, we try to find the priority of dissolving each factor among all the uneasy factors based on the information of stochastic composite importance. This would contribute for decision support to dissolve uneasy feeling and to get sense of security on foods.
A new algorithm for calculating the most reliable pair of disjoint paths in a network
Authors: Gomes Teresa , Craveirinha José , Violante Artur
Published: April 2024

In various types telecommunication networks, namely mobile ad hoc networks, WDM networks and MPLS networks, there is the necessity of calculating disjoint paths for given node to node connections in order to increase the reliability of the services supported by these networks. This leads to the problem of calculating a pair of disjoint paths (or a set of disjoint paths) which optimises some measure of performance in those networks. In this paper we present an algorithm, designated as OptDP, for obtaining the most reliable pair of disjoint paths based on the loopless version of MPS, a very efficient k-shortest path algorithm, and on Dijkstra algorithm. Since to the best of our knowledge there is no other proposal of an algorithm capable of solving exactly the same problem we perform a comparison with the application to this problem of the DPSP algorithm which calculates a set of disjoint paths with high reliability. Also a comparison with a simplified version (designated as NopDP) of the proposed algorithm, which stops after a maximal number F of candidate pairs of paths have been found, is presented. The comparison also includes the percentage of cases in which both algorithms were not capable of finding the optimal pair.
Technology and change: the role of information technology in knowledge civilization
Authors: Wierzbicki Andrzej Piotr
Published: April 2024

The paper presents a reflection on the role of technology and, in particular, information technology in the era of knowledge civilization. Diverse perceptions of this era, the concepts of three civilization eras versus three waves, of a cultural platform versus an episteme of a civilization era, of a big change at the end of industrial civilization era are outlined. The first principle of cultural anthropology and the concept of cultural imperialism are recalled. The contemporary philosophy of technology is shortly reviewed. An interpretation of Die Technik und die Kehre of M. Heidegger from a technological point of view is given. It is shown that we should distinguish technology proper from the system of its socio-economic applications, and that the relation of technology proper to hard science and to socio-economic applications of technology forms two positive feedback loops; the one of socio-economic applications might be more dan- gerous in cases of social infatuation with technological possibilities or other misapplications of technology. It is shown that the technology of knowledge civilization era will differ from that of industrial era in proposing boundless number of diversified technological possibilities; thus, the Heideggerian warning against social infatuation with technological possibilities must be not only repeated, but also modified and strengthened.

Published: April 2024

The paper describes results of introductory research focused on possibility to use location data available in a mobile network for the analysis of transport system status and efficiency. The details of a system capable of detecting abnormal traffic situation (accidents, heavy congestion) are described. This system (called VASTAR) uses a neural network to learn and store certain characteristic of the analyzed part of a road system. Based on a measured divergence from normal characteristic, a notification about non-typical situation is triggered. The results of a computational experiment using real-world location data and simulation of abnormal situation are provided. The proposed system can be a relatively low cost way to improve competitiveness of a mobile network operator by allowing him to offer new type of informational service. It could also aid municipal authorities by providing support for decisions regarding road traffic control and management and be used by emergency services as a monitoring an alarming tool for detecting abnormal road traffic situations when other means of observation are unavailable.

On MILP Models for the OWA Optimization
Authors: Ogryczak Włodzimierz , Olender Paweł
Published: April 2024

The problem of aggregating multiple outcomes to form overall objective functions is of considerable importance in many applications. The ordered weighted averaging (OWA) aggregation uses the weights assigned to the ordered values (i.e., to the largest value, the second largest and so on) rather than to the specific coordinates. It allows to evaluate solutions impartially, when distribution of outcomes is more important than assignments these outcomes to the specific criteria. This applies to systems with multiple independent users or agents, whose objectives correspond to the criteria. The ordering operator causes that the OWA optimization problem is nonlinear. Several MILP models have been developed for the OWA optimization. They are built with different numbers of binary variables and auxiliary constraints. In this paper we analyze and compare computational performances of the different MILP model formulations.
Secure Biometric Verification Station Based on Iris Recognition
Authors: Czajka Adam , Piech Krzysztof
Published: April 2024

This paper describes an application of the Zak-Gabor-based iris coding to build a secure biometric verification station (SBS), consisting of a professional iris capture camera, a processing unit with specially designed iris recognition and communication software, as well as a display (LCD). Specially designed protocol controls the access to the station and secures the communication between the station and the external world. Reliability of the Zak-Gabor-based coding, similarly to other wavelet-based methods, strongly depends on appropriate choice of the wavelets employed in image coding. This choice cannot be arbitrary and should be adequate to the employed iris image quality. Thus in this paper we propose an automatic iris feature selection mechanism employing, among others, the minimum redundancy, maximum relevance (mRMR) methodology as one, yet important, step to assess the optimal set of wavelets used in this iris recognition application. System reliability is assessed with approximately 1000 iris images collected by the station for 50 different eyes.
Competition and Diffusion of Telecommunication Services: The Multimedia Communication Services in Brazil
Authors: Rauen Cristiane Vianna
Published: April 2024

This paper aims to discuss the recent trends in the regulation of telecom services regarding the diffusion of broadband. To this matter, it compares the recent international competition regulation experiences to the Brazilian scenario. Considering that the telecom sector passed through huge technological and structural transformations in the last decades (from typical voice communications to convergent services based on broadband, and from voice services monopoly to multiple services oligopoly), its regulatory framework has also changed. Lately, several countries – such as the United States, the Netherlands, Korea and Chile – have established inter and intra-platform competition regulations in order to expand the access to the new forms of communications based on broadband. In Brazil, such mechanisms are not fully explored, and the country has lots of areas in which there is no competition in broadband services (known as multimedia communication services). As a result, Brazil has one of the highest prices of broadband services and one of the lowest levels of broadband penetration. In this way and considering international success in expanding services through competition, the paper defends that such mechanisms should be reinforced in the Brazilian broadband market.
Connecting for Surgery: The Belgian Use Case on the Legal Aspects of the Digital Operating Room
Authors: Vandezande Niels , Verhenneman Griet , Dumortier Jos
Published: April 2024

Telecommunications technology is making its way into operating rooms by new developments in e-health. However, conflicts arise with existing legal principles regarding data protection. This paper deals with key elements of the interactions between data protection and evolution in e-health. The scope will be the digital operating room, where different health services and activities converge through networked technology, raising a number of privacy-related issues. For instance, the patient’s health records and tools for recording surgical procedures could be integrated within the same platform, potentially leading to sensitive personal data linkage. Also the possible duration and reason of storage of surgical recordings, is a matter that remains largely unresolved in current practice. First, this paper will analyze the data exchanges of the digital operating room. As these will include personal patient data, it must be assessed whether and how the European framework on data protection can apply. Second, the regulatory regime of the manufacturers of the devices of the digital operating room will be analyzed. Can the current legal framework relating to e-health provide for suitable regulation for such devices? Drawing from experience gained in research projects, this paper aims to provide practical answers to often theoretical questions.
Reliable and High QoS Wireless Communications over Harsh Environments

Published: April 2024

One of the most challenging research fields in which research community has taken a very active role is focused on trying to bring the features of wireless networks into line with the traditional wired solutions. Given the noisy and lossy nature of the wireless medium, it is more difficult to provide a comparable Quality of Service (QoS) and Reliability over wireless networks. This lack of reliability avoids the use of wireless solution in scenarios under harsh environment and mission-critical applications. In this paper we propose an inter-node collaborative schema with the aim of improving the achievable QoS level for multicast streaming, through the use of Network Coding and the algebra it is based on. We also present an implementation of the described algorithm on the OPNET discrete event simulation tool. Experimental results highlighting the performance achieved by the proposed algorithm and its improved efficiency as compared to other solutions are described.
Innovative Method of the Evaluation of Multicriterial Multicast Routing Algorithms
Authors: Stachowiak Krzysztof , Zwierzykowski Piotr
Published: April 2024

Theoretical considerations of the multicast Quality of Service (QoS) routing have been a rapidly developing and dynamic research area for years. Several algorithms derived from different approaches have been proposed, while the pool of valid solutions to the problem is steadily growing. When new solutions are compared with their predecessors, as much information as possible about their characteristics and differences is needed. Both the graph theory and the optimization theory provide robust and objective means of comparing not only algorithms, but also the results they produce. However, any possible extension to the comparison methods is vital and can bring interesting new information that would eventually lead to innovative conclusions. This article presents a method, derived from practice and experience, that simulates the drainage of resources accumulated by consecutive communication allocations. The nature of this comparison is an extension to the classical measurement of the success ratio and this creates a context of the continuous measure of a success rather than a simple binary value. In this article such a method with regard to algorithms optimizing multicast problems for more than two criteria is used for the first time and leads to an interesting conclusion about the influence of the number of the criteria on the result.
Quality Aware Virtual Service Delivery System
Authors: Fraś Mariusz , Kwiatkowski Jan
Published: April 2024

The problem of providing support for quality of service (QoS) guarantees is studied in many areas of information technologies. In recent years the evolution of software architectures led to the rising prominence of the Service Oriented Architecture (SOA) concept. For Web-based systems there are three attributes that directly relate to everyday perception of the QoS for the end user: availability, usability, and performance. The paper focuses on performance issues of service delivery. The architecture of Virtual Service Delivery System (VSDS), a tool to serve requests for synchronized services is presented. It is proposed suitable monitoring technique used for estimation of values of service parameters and allocation of communication and execution resources by means of service distribution. The paper also presents results of experiments performed in real environment that show effectiveness of proposed solutions.

This paper describes the performance of various methods of QoS assurance for each connection in an environment composed of virtual networks and dedicate end-to-end connections inside them. The authors worked on the basis of research conducted with the use of the authorial network management system named Executed Management, which uses resources virtualization platforms VMware and Mininet for testing purposes. We briefly describe our system and techniques we used and some alternatives we tested and discarded because of their limitations. Functionality and performance of proposed solution to widespread implemented mechanisms as OpenFlow and MPLS are compared. Reasons for selecting well-known techniques to isolate networks and limit bandwidth on different levels of virtualization are considered. The purpose of this paper is to show out our studies and performance we achieved.

Authors: Danilewicz Grzegorz , Dziuba Marcin
Published: April 2024

In this paper, the Maximal Size Matching with Permanent Selection (MSMPS) scheduling algorithm and its performance evaluation, under different traffic models, are described. In this article, computer simulation results under nonuniformly, diagonally and lin-diagonally distributed traffic models are presented. The simulations was performed for different switch sizes: 4×4, 8×8 and 16×16. Results for MSMPS algorithm and for other algorithms well known in the literature are discussed. All results are presented for 16×16 switch size but simulation results are representative for other switch sizes. Mean Time Delay and efficiency were compared and considered. It is shown that our algorithm achieve similar performance results like another algorithms, but it does not need any additional calculations. This information causes that MSMPS algorithm can be easily implemented in hardware.
Cooperative Games with Incomplete Information for Secondary Base Stations in Cognitive Radio Networks
Authors: Martyna Jerzy
Published: April 2024

Cognitive radio (CR) technology is considered to be an effective solution for enhancing overall spectrum efficiency. Using CR technology fully involves the providing of incentives to Primary Radio Networks (PRNs) and revenue to the service provider so that Secondary Base Stations (SBSs) may utilize PRN spectrum bands accordingly. In this paper, a cooperative games with incomplete information for SBSs in a CR network is presented. Each SBS can cooperate with neighboring SBSs in order to improve its view of the spectrum. Moreover, proposed game-theory models assume that the devices have incomplete information about their components, meaning that some players do not completely know the structure of the game. Using the proposed algorithm, each SBS can leave or join the coalition while maximizing its overall utility. The simulation results illustrate that the proposed algorithm allows us to reduce the average payoff per SBS up to 140% relative to a CR network without cooperation among SBSs.
