Authors: Hosseinabadi-Farahani Mohammadjavad , Fallahi-Khoshknab Masoud , Arsalani Narges , Hosseini Mohammadali , Mohammadi Eesa
Published: February 2021

BACKGROUND:

Discrimination in health care is a common phenomenon whose complete understanding has always been a major concern of health-care systems to control and reduce it. This study aimed to explore the experiences of unintentional discrimination and related factors in health-care providers.

MATERIALS AND METHODS:

This qualitative study was conducted with a content analysis approach in 2019. Data were collected through semi-structured interviews with 13 health-care providers including two physicians, three nursing supervisors, two head nurses, four staff nurses, and two nurse aides in two general hospitals in Tehran, Iran. Participants were selected through purposeful sampling. The obtained data were analyzed by Graneheim and Lundman method.

RESULTS:

Three main categories and eight subcategories were obtained from the data analysis: (1) forced discrimination (superiors' pressures and executive orders, occupational concerns, and fear of the superiors); (2) guided discrimination (professional challenges, managers' policymaking, and lack of medical ethics knowledge); and (3) lack of resources (workforce shortage and lack of medical equipment).

CONCLUSION:

The results of this study suggest that health-care providers such as doctors and nurses are unintentionally forced to provide discriminatory care on some occasions. Knowing and managing these unwanted factors can partly counteract unintentional discrimination. Thus, preventing the factors that lead to superiors' pressures and occupational forces and improving the medical ethics knowledge should be considered by health-care managers.
The Role of Echocardiography in Heart Failure Today
Authors: Pinto Jostol , Koshy A. George
Published: February 2021

Although heart failure (HF) is often defined clinically, it has a large pre-clinical spectrum and its diagnosis, staging, response to therapy, and etiology are often determined by echocardiography. Understanding of pathophysiologic nuances in HF is significantly aided by the novel parameters that modern echocardiography can assess today, especially in the field of diastolic function and imaging of strain. This article attempts to link the understanding of the progression of HF with an applicable echocardiographic approach to patients at any point in this progression, sometimes in special clinical scenarios. It also conveys that how systolic and diastolic dysfunction is not mutually exclusive but can be assessed separately or simultaneously. Early HF can be subclassified based on myocardial deformation being dysfunctional either longitudinally or circumferentially. An insight into right ventricular evaluation is also included here.

Background:

Tuberculous constrictive pericarditis (CP) is a chronic inflammatory disease by Mycobacterium tuberculosis affecting the pericardium, occurring mainly in developing nations. The aim of this study was to evaluate left atrial (LA) and left ventricular (LV) myocardial mechanics in tuberculous CP using standard two-dimensional (2D) echocardiography and speckle tracking echocardiography (STE).

Methods:

A prospective observational echocardiographic study of 30 subjects was performed: 15 patients with tuberculous CP and 15 controls. 2D echocardiography, color Doppler imaging, and tissue Doppler imaging (TDI) were performed along with STE to evaluate the LV and LA mechanics.

Results:

We found that the global circumferential strain (GCS, P = 0.002) and the global longitudinal strain (P = 0.02) were significantly reduced in patients with CP compared with controls. The longitudinal lateral wall strain was significantly reduced (P = 0.001) in CP patients, whereas longitudinal septal strain was not reduced significantly (P = 0.18) in CP patients compared with controls. The longitudinal lateral strain was significantly reduced as compared to the longitudinal septal strain (P = 0.001) within the CP group (strain reversus). Annulus reversus (medial early diastolic mitral annular velocity [e'] > lateral e') by TDI was observed in 11 cases out of 15 in tuberculous CP group, whereas strain reversus (septal strain > lateral strain) was seen in all cases of CP group. The LA reservoir strain showed a statistically significant reduction in CP patients (P = 0.001) compared to controls.

Conclusions:

“Strain reversus” and reduced GCS are characteristic imaging findings on STE in patients with tuberculous CP and may provide an additional parameter to conventional echocardiography in the diagnosis of tuberculous CP.
The technique of precise and systematic vascular control during robotic pancreaticoduodenectomy for periampullary and pancreatic tumours
Authors: Kalayarasan Raja , Gautham M. S. , Gnanasekaran Senthil , Pottakkat Biju
Published: February 2021

Robotic pancreaticoduodenectomy (PD) remains one of the most advanced robotic procedures. Improved ergonomics and stable 3D vision with robotic platform helped overcome the technical challenges of pancreatic reconstruction in minimally invasive PD. However, inadequate understanding of the complex vascular anatomy of the pancreatic head and uncinate process often results in intra-operative bleeding and prolongs the learning curve. The technique of precise identification and systematic control of the vessels supplying the head and the uncinate process is described in this report. A good understanding of the common vascular anatomy and variations along with stepwise precise vascular control described in this report could minimise intra-operative bleeding and shorten the learning curve associated with robotic PD.

Myocardial infarction (MI) with nonobstructive coronary arteries (MINOCA) is syndrome with clinical evidence of acute MI (AMI) with normal coronary arteries. This study reports the case of a 23-year-old single woman referring to the hospital with clinical manifestations of MI, with electrocardiography findings of slow ventricular tachycardia or accelerated idioventricular rhythm and atrioventricular dissociation, and high troponin levels, which was admitted with the diagnosis of MINOCA due to mental stress (grief) and was discharged after 4 days of monitoring and following stabilization of conditions and absence of symptoms. Other causes of MINOCA ruled out through imaging studies. Mental stress can lead to MINOCA.
Skin and metabolic syndrome
Authors: Adibi Neda , Robati Reza M
Published: February 2021

Metabolic syndrome (MeTS) is a well-known health-related problem with several end-organ damages and the resulted side effects such as rising in the blood glucose and lipid and blood pressure. Although MeTS might show several skin symptoms such as acanthosis nigricans, skin tags, acne, and androgenic alopecia, it could also be implicated in the pathophysiology of numerous dermatologic disorders. Furthermore, some dermatologic drugs might be implicated in the incidence or exacerbation of MeTS. Consequently, MeTS and skin problem could interfere closely with each other and each one could predispose the patient to the other one and vice versa. Remembering these close relationships help us to have better therapeutic choices regarding each inflammatory skin conditions. Moreover, some of the skin symptoms should be followed cautiously to define the underlying MeTS.

Published: February 2021

A rare case reporting the occurrence of full-thickness macular hole (MH) formation following intravitreal antivascular endothelial growth factor injection in a case of hemicentral retinal vein occlusion and the subsequent management of the case. As described in few other similar case reports in the literature, there are quite a few probabilities of factors causing this pathology. An acute posterior vitreous detachment or sudden decompression of the macular edema can quite possibly lead to the above situation. This case report shares light on the evolution of a MH following intravitreal injection and the subsequent treatment process.

Published: February 2021

Dome-shaped macula (DSM) is a recently described entity characterized by convex protrusion of the macula within a posterior staphyloma. Serous macular detachment is the most common complication, but the condition often remains stable despite lack of intervention. Spontaneous resolution of the condition has also been reported in many cases. The condition may be observed with periodic review with optical coherence tomography (OCT). We report a 56-year-old Omani woman, a high myope without significant ocular complaints who was incidentally detected to have bilateral DSM with serous macular detachment and review the literature regarding its diagnosis, pathogenesis, and treatment options. As the patient was asymptomatic, she was followed with serial OCTs for 6 months and is stable in terms of visual acuity and subretinal fluid.

Authors: Meel Rachna , Dhiman Rebika , Vanathi Murugesan , Sen Seema , Gupta Noopur , Tandon Radhika
Published: February 2021

BACKGROUND:

To evaluate the role of interferon alpha 2b (IFNα2b) in the management of primary/recurrent cases of ocular surface squamous neoplasia (OSSN).

METHODOLOGY:

Medical records of 27 OSSN cases managed with IFNα2b (topical drops and/or perilesional injection) in 1 year were retrospectively reviewed.

RESULTS:

The median age of presentation was 60 years with a male: female ratio of 3.5:1. American Joint Commission on Cancer tumor grading was T1 in 1 eye (3.7%) and T3 in 26 eyes (96.3%). Eighteen cases were treated with topical drops (1 million IU/ml), 4 cases with perilesional subconjunctival injection (3–6 million IU/ml), and 5 cases with combined therapy. Overall, treatment response was seen in 88% cases. Complete regression was achieved in 80% cases. Median time to complete regression of tumor was 3 months (range 1–11 months) in cases treated with topical interferon therapy and 2.5 months (range 0.7–3 months) in cases managed with injections or a combination of the two. The mean duration of follow-up was 24 months. All cases with partial/no response showed complete regression on subsequent management with topical mitomycin C. None of the patients required surgery. Acute ocular surface congestion was seen in two patients necessitating discontinuation of therapy.

CONCLUSION:

In view of excellent treatment outcome and few side-effects, interferons can be considered as a primary, safe, and cost-effective treatment option for OSSN not only in tertiary centers but also by peripheral ophthalmologists.

Published: February 2021

AIM:

To evaluate the postoperative visual acuity and complications in eyes with ectopia lentis in children who underwent lens removal and then implantation of retropupillary fixated iris claw lens versus scleral fixated intraocular lens (SFIOL) implantation.

MATERIALS AND METHODS:

A retrospective analysis of pediatric cases who presented with lens subluxation secondary to ectopia lentis and who underwent lens extraction (57 eyes of 38 patients) with either retropupillary iris fixated intraocular lens (IOL) implantation (Group A – 36 eyes of 20 patients) and SFIOL implantation (Group B – 21 eyes of 18 patients) was done over a period of 5 years from March 2010 to February 2015. The main outcome measures were preoperative and postoperative best-corrected visual acuity (BCVA) and secondary postoperative complications.

RESULTS:

The study patients were divided into two groups: Group A patients were implanted with retropupillary iris claw lens whereas Group B patients were implanted with SFIOL. The mean age of presentation was 12 years, the mean follow-up period was of 24 months (range 14–36 months), and the median follow-up period was 26 months in both the groups. An improvement in the mean BCVA (LogMAR) was seen in both the groups. In Group A, the mean BCVA improved from 1.5 ± 0.2 preoperatively to 0.3 ± 0.2 postoperatively, whereas in Group B, the mean BCVA improved from 1.5 ± 0.3 preoperatively to 0.3 ± 0.2 postoperatively (P < 0.001). None of the eyes in either of the groups had any serious complications such as glaucoma, uveitis, cystoid macular edema, or endophthalmitis.

CONCLUSION:

Retropupillary iris fixation and scleral fixation of IOL are both safe and viable options for the correction of ectopia lentis in pediatric age group.

Authors: Schnyder Flurin , Cabalzar-Wondberg Daniela , Raptis Dimitri A. , Eisner Lukas , Zuber Markus , Weixler Benjamin
Published: February 2021

BACKGROUND
Neurological disturbances after open inguinal hernia repair affect approximately one in ten patients. Sutureless, self-gripping meshes were developed with the aim of reducing postoperative neurological disturbances or neuralgia. This study assessed short- and long-term outcomes after open inguinal hernia repair using a self-gripping light-weight mesh in a peripheral teaching hospital.

METHODS
Patients with uni- or bilateral inguinal hernia were included in this study. Open inguinal hernia repair was performed according to the Lichtenstein technique with a self-gripping, lightweight macroporous mesh. Postoperative follow-up was at 6 weeks after surgery and any long-term complications or recurrences were recorded up to 5 years postoperatively.

RESULTS
The median follow up time for all patients was 5–6 years and the median operation time was 40.0 minutes (inter quartile range 25.0–55.8). Of the 162 included patients, the mean numeric rating scale for pain (0 = no pain, 10 = excruciating pain) before hospital discharge was 2.7 (standard deviation [SD] 2.6) and 1.1 (SD 1.1) at 6 weeks postoperatively. The overall incidence of neurological disturbances at 6 weeks postoperatively was 11% when surgery was performed by the chief of surgery and 40% when it was performed by a senior consultant, 49% by chief-residents and 47% by supervised residents (p = 0.005). Patients with neurological disturbances were younger than asymptomatic patients (age 50, SD 15 vs 62, SD 17, p <0.001). The 1-, 3- and 5-year recurrence rates were 1%, 2% and 3%, respectively.

CONCLUSIONS
This study shows that open inguinal hernia repair using a self-gripping mesh is feasible, with a short operation time and low hernia recurrence rates in a peripheral teaching hospital. However, significant differences in neurological disturbances dependent on the surgeons experience were identified. Especially younger patients should be operated on by an experienced surgeon to reduce neurological disturbances and neuralgia.

Velocity distribution of 43Ca+ion cloud in the low temperature limit in a quadrupole Penning Trap
Authors: B M Dyavappa
Published: February 2021

Penning trap has electric field created by DC voltage applied between ring and end cap electrodes and magnetic field is applied along symmetry axis, as the electric field confines ions in the axial direction through an electric potential minimum and the magnetic field confines the ions in the radial direction. The trapping potential created by the DC voltage applied between the end cap and ring electrodes in the low temperature limit is cancelled by Coulomb interaction of ions and the total energy is mainly kinetic energy of ions. The velocity distribution of 43Ca+ ions along axial direction, in radial plane and total velocity distribution due to resulting motion of both axial and radial motion of ions in low temperature limit in a Quadrupole Penning trap are presented here. These results reveal the properties of 43Ca+ ion cloud and are useful to study confining techniques for different types of ions in low temperature limit and a qubit can be encoded in the hyperfine ground states of 43Ca+ isotope for ion trap quantum computation.
THE ENTREPRENEURIAL DECISION MAKING: USE OF EFFECTUATION AND RELATION WITH PERCEIVED FINANCIAL PERFORMANCEAND INNOVATION IN THE FIRM
Authors:   SZABIST, Karachi, Rizvi Subeika
Published: February 2021

During the start of the venture entrepreneurs rely on a number of techniques and strategies to make decisions. Effectuation and causation are important modes of this decision making process. The theory on effectuation is advancing from an early to a mature phase globally thus it’s important to understand its dimensions and their influence on the firm’s performance. This study explores the use of this effectual logic in micro and small firms operating in Pakistan and its influence on the financial performance and level of innovation in these firms. Although few researches have been focused on the antecedents and dependents of effectuation but none have arrived at a consensus on the appropriate variables. In Pakistan, as it’s a relatively new concept although being applied, there is all the more need to assess the nature of effect these variables could have on some of the important outcomes of the firm. This research contributes to existing literature by providing relationship of effectuation with, another important, variable of innovation in the firm. In this empirical study, a sample of 166 micro and small firm entrepreneurs was used all operating businesses within Pakistan. A survey, through a questionnaire, was conducted using snowball sampling. Findings indicate that use of effectuation is positively correlated with both higher perceived financial performance and level of innovation employed in the firms. Also not all effectual constructs have uniform influence on the variables which explains the formative nature of the logic of effectuation. A few implications of this study and future research areas have also been identified.

Published: February 2021

Low temperature stress can lead to variety of changes, including apoptosis in tilapia (Oreochromis niloticus). The B cell lymphoma-2 (Bcl-2) gene family plays an important role in the process of apoptosis. The present study conducted genome-wide characterization of the Bcl-2 family genes in tilapia and their mRNA expression profiles were analysed in different tissues of tilapia under the low temperature stress (10°C). Twenty-four Bcl-2 family genes were identified, containing 2~8 exons. These genes were classified into two subfamilies (Bcl-2 homologs and BH3-only) based on their conserved domains. Besides, these BCL-2 proteins in tilapia possess at least one of the four conserved BH domains. The phylogenetic analysis showed that the Bcl-2 family genes did not aggregate by species, demonstrating sequence conservation of different types of Bcl-2 family members. Real-time quantitative PCR (RT-qPCR) analysis showed that Bcl-2 family genes were broadly expressed in different tissues of tilapia. When reared at 10 °C, the transcriptional expression levels of most of anti-apoptotic Bcl-2 homologs subgroup members and other BH3-only subgroup members in most tissues of tilapia were higher than those at 30°C. However, most of other Bcl-2 family members revealed a lower expression. The results suggested that hypothermia had significantly induced apoptotic in tilapia.

Published: February 2021

Particle swarm optimizer is one of the searched based stochastic technique that has a weakness of being trapped into local optima. Thus, to tradeoff between the local and global searches and to avoid premature convergence in PSO, a new dynamic quantum-based particle swarm optimization (DQPSO) method is proposed in this work. In the proposed method a beta probability distribution technique is used to mutate the particle with the global best position of the swarm. The proposed method can ensure the particles to escape from local optima and will achieve the global optimum solution more easily. Also, to enhance the global searching capability of the proposed method, a dynamic updated formula is proposed that will keep a good balance between the local and global searches. To evaluate the merit and efficiency of the proposed DQPSO method, it has been tested on some well-known mathematical test functions and a standard benchmark
problem known as Loney’s solenoid design.

A re-examination of the conflict rules governing the validity of international contracts
Authors: Obiri-Korang Prince
Published: February 2021

Generally, under choice of law, the issue of uncertainty associated with the determination of the governing law of international contracts is quite clear. The level of this uncertainty, however, increases when dealing with questions about which law governs the validity of such contracts. Like other areas of private international law, matters concerning validity present several unique challenges both in theory and in practice, making it the most complicated topic in private international law literature. In fact, the uncertainty in this area has led to a situation where different rules are applied by different states, without taking into consideration the link that should exist between the state whose law becomes applicable and the function that the law is expected to serve – determining the validity of a contract. This article attempts to contribute to existing literature on choice of law questions regarding the validity of international contracts and also provides solutions, based on the underlying principles of private international law of contract that effectively address the uncertainty in this area of law. The article submits that the law that governs the validity of an international contract must, at all times, be one that has a legitimate interest in matters concerning the legality or otherwise of such contracts. In this regard, the article strongly opposes the theory that the parties’ intention determines the law that governs the validity of their contract. After a careful examination of literature and landmark judicial decisions in both civil law and common law jurisdictions, the article concludes that the lex loci solutionis is the appropriate law to determine matters relating to the validity of international contracts.
The impact of marine spatial planning legislation on environmental authorisation, permit and licence requirements in Algoa Bay
Authors: Metuge Denning
Published: February 2021

With a focus on Algoa Bay, this article considers the potential conflicts that may arise between South Africa’s marine spatial planning (MSP) legislation and the environmental authorisations, permits and licencing requirements provided under specific environmental management Acts (SEMAs). The legislation for MSP in South Africa is the Marine Spatial Planning Act, 2018 (MSPA). It provides that ‘[a]ny right, permit, permission, licence or any other authorisation issued in terms of any other law must be consistent with the approved marine area plans’. What is more, where there is a conflict between the MSPA and any other legislation ‘specifically relating to marine spatial planning’, the provisions of the MSPA prevail. Particular attention is given to the principle of sustainability that the MSPA incorporates into MSP and its impact on environmental authorisation, permit and licence requirements issued in terms of three SEMAs: the National Environmental Management: Biodiversity Act, 2004 (NEM:BA), the National Environmental Management: Protected Areas Act, 2003 (NEM:PAA) and the National Environmental Management: Air Quality Act, 2004 (NEM:AQA). The article concludes by summarising the potential impact the MSPA will have on the discussed SEMAs when it comes into operation and makes recommendations to prevent the occurrence of potential conflicts.

Published: February 2021

Due to its unique geographical location, for thousands of years the region of Bulgaria used to be a crossroads for many nationalities. The enormous Bulgarian cultural and historical heritage is little known outside the country and modern information and communication technologies have not been used in their full potential to promote and advertise it. In this paper, a personal tourist guide is presented, which is able to generate cultural routes. The routes can be virtual or real depending on preferences or location of the user. The architecture of the guide consists of several intelligent agents that work with ontology network and ambient network as a knowledge base, to generate the tourist routs. Ontologies present the cultural and historical objects of Bulgaria according the CCO standard, and ambient present the physical properties (location, working time etc.) of these objects. Furthermore, the dynamic generation of routes is demonstrated by modeling ambient-oriented approach.
APPROACH FOR MINIMIZATION OF PHONEME GROUPS IN AUTHORSHIP ATTRIBUTION
Authors: Khomytska Iryna , Teslyuk Vasyl , Bazylevych Iryna , Shylinska Inna
Published: February 2021

The developed mathematical support for authorship attribution software includes a combination of statistical methods (Student’s t-test, Kolmogorov-Smirnov’s test) and a statistical model for determining significant differences between styles. The combination of statistical methods allows us to enhance test validity of authorship attribution by obtaining the same results by the two methods applied. The model developed makes it possible to identify a consonant phoneme group with high style identification capability. The phoneme position in a word is taken into account. The greater number of significant differences is, the higher authorship identification capability of the phoneme group is. The developed system software is based on the algorithms of the used combination of methods and statistical model. The Java programming language provides platform independence. The minimized number of consonant phoneme groups makes the process of style and authorship attribution more automated. The obtained results of comparisons of the scientific, belles-lettres, conversational and newspaper styles are presented. The data obtained allows us to assert that the used combination of methods and the developed statistical model improve test validity of style and authorship attribution.

In this work, we draw attention to prediction of football (soccer) match winner. We propose the deep multilayer neural network based on elastic net regularization that predicts the winner of the English Premier League football matches. Our main interest is to predict the match result (win, loss or draw). In our experimental study, we prove that using open access limited data such as team shots, shots on target, yellow and red cards, etc. the system has a good prediction accuracy and profitability. The proposed approach should be considered as a basis of Oracle engine for predicting the match outcomes.

In this paper, we propose a method for using neural networks to model impacts on the parameters of complex IT projects for the creation of distributed information systems. The method allows predicting the level of changes in the results of the project activity at any time during the execution of projects and depending on changes in the time parameters of projects. An integrated information system is developed for modelling the changes of key parameters of IT projects using cloud data warehouses. The modern information technologies of management projects of leading developers are involved and integrated in the process of modelling. The evaluation of the results of modelling the effects of changes on the timing of work implementation is carried out taking into account the context characteristics of projects, including resource distribution both in time and in project work, cost distribution, etc. The model of in-depth training of the neural network is proposed, due to the experimental representation of the input and output data of numerical experiments. In this paper we propose a method for analysing the effects of changes on the terms of project execution.

A number of research initiatives have recently been launched around the world regarding the conceptualization, specification, design and development principles of the future use of credit cards, storing secret information on them, while most time we use them for online payment. In addition, if it has enough money, we can pay for what we need at any time. Therefore, the goal of this proposed research is to use data mining techniques to predict credit card payment next month. Our proposed system contains five steps: (a) find the suitable database from the internet because this database is not available in Iraq, (b) pre-process the credit card database based on person correlation matrix to determine which feature is less correlated with other to remove it and reduce the time of prediction, (c) split pre-processing database into two parts training and testing dataset, (d) apply TreeNet prediction data mining techniques (TPDMT) on training dataset to test if we need payment next month or do not, find the optimal tree. TreeNet based on Boosting Machine usually makes the predictor to use Decision Trees (DTs). (e ) Finally, pass the testing dataset on the optimal tree results from TPDMT, then using the five measures related to confusion matrix to evaluate the results including “Accuracy (AC), recall or true positive rate (TP), precision (P), F-measure (considers both precision and recall) and Fb”.

Published: February 2021

Association rule mining plays a very important role in the distributed environment for Big Data analysis. The massive volume of data creates imminent needs to design novel, parallel and incremental algorithms for the association rule mining in order to handle Big Data. In this paper, a framework is proposed for incremental parallel interesting association rule mining algorithm for Big Data. The proposed framework incorporates interestingness measures during the process of mining. The proposed framework works to process the incremental data, which usually comes at different times, the user's important knowledge is explored by processing of new data only, without having to return from scratch. One of the main features of this framework is to consider the user domain knowledge, which is monotonically increased. The model that incorporates the users’ belief during the extraction of patterns is attractive, effective and efficient. The proposed framework is implemented on public datasets as well as it is evaluated based on the interesting results that are found.

Published: February 2021

This article describes the original method of automatic summarization of scientific and technical texts based on rhetorical analysis and using topic modeling. The proposed method combines the use of a linguistic knowledge base and machine learning. For the detection of key terms, we used topic modeling. First, unigram topic models containing only one-word terms are constructed. Further, these models are extended by adding multiword terms. The most significant fragments of the original document are determined in the process of rhetorical analysis with the help of discursive markers. When evaluating the importance of text fragments, keywords, multiword terms, and scientific lexicon characterizing scientific and technical texts are also taken into account. A linguistic knowledge base has been created to store information about the markers and scientific lexicon. The experiments showed that this method is effective, needs a comparatively small amount of training data and can be adapted to processing texts of different subject fields in other languages.

Published: February 2021

Quality of live video streaming technology is based on quality of Experiences parameters (QoE). Approaching the peer-to-peer (P2P) or peer-assisted networks as a sympathetic solution is highly required, especially in light of its authentic scalability and its extremely low initial cost requirements. However, the design of robust, efficient, and performing P2P streaming systems remains a high challenge when real-time constraints are part of the quality of service (QoS), as in TV distribution or conferencing applications. One of the P2P main issues that affect the quality of streaming is the neighbor selection methodology. The proposed work presents an effective mesh-based neighbor selection approaches for video streaming – Uniform Peer Distribution Algorithm (UPDA) – based on QoS and QoE Parameters. UPDA shortens the latency to be ranging from 10 ms to 50 ms servicing up to 4000 online peers under failure / recovery tests. Simulation results demonstrate that the proposed UPDA achieves good performance in End-to End delay with a percentage of 10.4 % and packet delay variation about 2% compared to random neighbor selection method.

The problem of a robotic system creating for plasma spraying of biocompatible coatings on complex shaped implants based on a Fanuc LR Mate 200 id manipulation robot and modeling spraying trajectories using a virtual simulator Roboguide V6.40 is considered. Parametric classification of implants is carried out whenever possible by plasma spraying using robotic devices. The main procedures for implants preparation for spraying were investigated. The 3D UNIVERSE scanner is used for scanning the implant and building its spatial model, the 3D model of the implant is being developed in Geomagic Design X. To build the manipulator program movements taking into account the speed of movement, it is proposed to use fourth order splines, which is built in the Matlab tools with finding of the optimal close spline to the original values. As the example of Cox femoral joint implant, a simulation of robot motion is performed using a virtual simulator Roboguide V6.40 with the possibility of transferring the program to a real Fanuc LR Mate 200 id robot.

Published: February 2021

The features of integrity monitoring of FPGA-based safety-critical systems are considered. Hardware Trojans are distinguished as one of the most dangerous types of malicious integrity violation of FPGA-based systems. The study has proved that Hardware Trojans can be implanted into the system (or system project) during its planned modification. In particular, it happens when the integrity monitoring, based on the hash sum usage, does not operate. Before running the integrity monitoring, one should ensure that Hardware Trojans were not implanted. Authors proposed the method for detecting the hardware Trojans location in the space of FPGA-based components of safety-critical systems. The method is based on the analysis of addressing to the values of calculated LUT units for these components in the normal and emergency modes of system operation. The hardware module for addressing the registration in accordance with the proposed method is implemented.

Published: February 2021

The use of wireless sensor networks (WSN) in industry and for forest fire detection has recently become increasingly popular. Assessment of the availability of such networks is an important task, since they perform essential functions in critical situations. Sensor networks can be used to prevent and detect forest fires, and they must meet high availability requirements. Various options for organizing the WSN system are considered - with and without recovery. For such systems, the paper evaluates the probability of no-failure operation, as well as the readiness function, taking into account the network coverage ratio. In the paper the Markov WSN model for evaluating its availability function is developed taking into account the network coverage area. The obtained graphical dependencies allow us to evaluate how a change in the failure rate of sensors or system equipment affects the availability function value. The goal of this paper is to obtain metrics to assess the availability of system for monitoring forest by WSN and the availability function of a network using the Markov models. A special metric, so-called coverage availability factor is suggested in this paper taking into account different combinations of sensor failures which influence on completeness of monitoring forest fires.
