Published: July 2022

In order to investigate the pulse modulation potential of SnSe2 in all-solid-state lasers, an active and passive dual-loss-modulated (APDM) Q-switched and mode-locking (QML) Nd:YVO4 laser was realized by employing an acousto-optic modulator (AOM) and a 5.9 nm thick SnSe2 saturable absorber (SA). The significant pulse compression ability of SnSe2 film was found experimentally, and sub-nanosecond mode-locking pulses with large peak power were obtained. The average output power, pulse energy, and pulse width versus the pump power were measured. With a pump power of 8.5 W, 242 ps mode-locking pulses with a pulse peak power of 231.4 kW were realized successfully. The experimental results also show that the SnSe2-based APDM QML laser has great potential in generating sub-nanosecond pulses with large peak power and high stability.

Authors: Wu Daohua , Han Yashuai , Zhu Xuehua , Cao Zhuoliang
Published: July 2022

We report the generation of long-term stable squeezed vacuum states at 1064 nm using a degenerate optical parametric amplifier (DOPA) with a periodically poled KTiOPO4 crystal (PPKTP). The OPA is pumped by a 532 nm light produced by frequency doubling the fundamental light with a bow-tie enhancement second harmonic generator (SHG). When the DOPA and relative phases are locked using a dither-locking method, the squeezed vacuum states are stably measured over 2 h at 11 MHz. The highly compact and simple squeezed light source is suitable for applications in quantum optics experiments.

Published: July 2022

Tocopherol is vital for the nutritional value and stability of Indian mustard (Brassica juncea L. Czern and Coss) oil; nonetheless, the lack of information on genetic control is hampering its improvement. In this study, six populations (P1, P2, F1, F2, BC1P1, and BC1P2) of RLC3 × NPJ203 were evaluated in a family block design to evaluate the inheritance pattern, gene effects, and various other genetic parameters of tocopherol content (α, γ, and total), using generation mean analysis. The comparison of direct and reciprocal crosses indicated that the tocopherol content was not influenced by maternal inheritance. Negative directional heterosis showed that ATC, GTC, and TTC are governed by recessive genes. Potence ratio and degree of dominance highlighted an over-dominance type of gene interaction for GTC and TTC, whereas ATC was governed by epistatic interactions. Furthermore, the six-parameter model revealed a duplicate gene action for α-tocopherol content. Broad and narrow sense heritability coupled with genetic advances were high.

1–Methylcyclopropene (1–MCP) is used for extending the postharvest life of the avocado during storage. Evaluated the effect of 1–MCP application at different times after harvest, i.e., 0, 7, 14, and 21 d at 5 °C, to identify the threshold of the ethylene inhibition response in “Hass” avocado. Our results showed that fruits from two maturity stages at harvest: low dry matter (20–23%) and high dry matter (27%). Changes in ethylene production rates and transcript accumulation of genes involved in ethylene metabolism were measured at harvest and during storage. 1–MCP treated fruit up to 14 d of storage showed similar values of firmness and skin color as fruit treated at harvest time. In contrast, when the application was performed after 21 d, the fruit showed ripening attributes similar to those of the untreated ones. To further understand the molecular mechanisms responsible for the lack of response to 1–MCP at 21 d of storage, transcriptomic analysis was performed. Gene ontology analyses based on the DEG analysis showed enrichment of transcripts involved in the ‘response to ethylene’ for both maturity stages. All genes evaluated showed similar expression profiles induced by cold storage time, with a peak at 21 d of storage and an increased softening of the fruit and peel color. This was a two-year field study, and results were consistent across the two experimental years. Our results should help growers and markets in selecting the optimal timing of 1–MCP application in “Hass” avocados and should contribute to a deeper understanding of the molecular mechanisms of the avocado ripening process.

Published: July 2022

Olea europaea subsp. cuspidata has a relatively low commercial value due to the low size and pulp to stone ratio of its drupes compared to commercial olive cultivars. Nevertheless, this subspecies could represent a valid source of useful traits for olive breeding. In the current work, the drupe metabolic composition (secoiridoids, flavonoids, simple phenols, triterpenic acids, etc.) of a progeny of 27 cuspidata genotypes coming from free pollination and their female parent was evaluated by applying a powerful LC-MS method. A total of 62 compounds were detected within the profiles; 60 of them were annotated and 27 quantified. From a quantitative point of view, the genotypes from the progeny of cuspidata showed quite different metabolic profiles to olive common cultivars (“Arbequina”, “Frantoio”, “Koroneiki” and “Picual”) used as controls. Cuspidata drupes were richer in terms of several bioactive compounds such as rutin, hydroxytyrosol glucoside, a few interesting secoiridoids and the compounds of m/z 421 and 363. The relationships among several secondary metabolites determined in the progeny inferred from the results of both PCA and cross-correlation analysis were explained according to metabolic biosynthesis pathways in olive drupes. These outcomes underlined the potential of cuspidata genetic resources as a source of potentially interesting variability in olive breeding programs.

Published: July 2022

Multiphase pumps are used as an important tool for natural gas hydrate extraction owing to their excellent gas–liquid mixing and transport properties. This paper proposes an adaptive response surface-based integrated optimization design method. A model pump is designed based on the axial flow pump design theory. The model pump is numerically simulated and analyzed to obtain its performance parameters. Then the structural and performance parameters of the pump are parameterized to establish a closed-loop input–output system. Based on this closed-loop system, a sensitivity analysis is performed on the structural parameters of the impeller and guide vane, and the parameters that affect the performance of the gas–liquid hybrid pump the most are derived. The Sparse Grid method was introduced to design the experiment and construct the approximate model. The structural parameters of the impeller and guide vane are used as design variables to optimize the pressure increment and efficiency of the pump. After optimization, the pressure increment of the multiphase pump was increased by 10.78 KPa and the efficiency was increased by 0.89% compared to the original model. Finally, we validate the accuracy of the optimized model with tests.

Authors: Subramanian Aswinprakash , Thirunavukkarasu Jayaraman , Muthuraman Arunachalam
Published: July 2022

Retinopathy is one of the most common complications of diabetes mellitus. Diabetic retinopathy (DR) occurs due to microvascular damage in retinal tissues provoked by high blood sugar levels. The available drugs for DR are limited. Astaxanthin (AST) has anti-hypertensive, anti-obesity, and anti-diabetic properties. However, the therapeutic effect of AST on DR remains elusive. The present study is designed to investigate the effects of AST on DR via inhibition of neuron-specific enolase (NSE) activity. DR was induced by the administration of streptozotocin (STZ, 35 mg/kg: intraperitoneal; and 20 μL of STZ: intravitreal) in mice. AST (10 and 20 mg/kg) was administered orally (p.o.) for 21 days. The DR associated visual changes were assessed at different time intervals via optokinetic motor response (OMR) and penta-maze (PM) tests. Blood glucose level as well as retinal catalase, lactate dehydrogenase (LDH), & neuron-specific enolase (NSE) were estimated. The reference drug i.e., dexamethasone (DEX, 10 mg/kg; p.o.) was administered for 21 days. The administration of AST showed significant ameliorative potential in DR. Hence, AST can be used as a natural medicine for the management of DR due to its potential antioxidant, anti-diabetic, and NSE inhibitory properties.

Published: July 2022

Liquid fertilizers are mainly applied by spraying liquid fertilizer on the surface of crop leaves and by deep openings between rows. The first causes considerable environmental pollution, and the second can easily cause to damage the root system of crops. In this study, corn crops were taken as the study object and an efficient deep-hole application method for liquid fertilizer based on alternate drilling was proposed. The needle body is driven by the spur gear wheel system in a caving mechanism to puncture holes alternately in a vertical posture and high-speed punctures are implemented with less disturbance to the soil. The cylindrical hollow cam of the mechanism is controlled so that the fertilizer needle sprays fertilizer when injected into soil and stops injecting when pulled out of the soil. Based on the bench test, fertilizer injecting performance and energy saving performance of the differential two-way fertilizer supply distribution device were analyzed and the head loss for energy saving value is 2.1, 3.1, and 5.5 m. Based on numerous field tests, the puncture track, hole width, and hole spacing are analyzed under different puncture speeds. Field tests were carried out according to a quadratic orthogonal rotating combination design and the results show that when the fertilization depth for agronomic requirements is 80 mm and the machine work speed and forward speed are 127 r min−1 and 1.40 m s−1, respectively, the hole width is 39.9 mm, the hole spacing is 320 mm. The efficient deep-hole application method for liquid fertilizer based on alternate drilling can provide support for data analysis and theoretical design of liquid fertilizer deep application technology for corn crops.

Published: July 2022

Pore structure is the key factor affecting reservoir accumulation and enrichment behavior. Due to the complex mineral components and pore structure of shale oil reservoirs and strong heterogeneity, it is necessary to explore the micro-pore structure characteristics of inter-salt shale. In this study, in order to qualitatively and quantitatively analyze the pore structure of inter-salt shale reservoirs, as well as evaluate the mineral composition and its spatial distribution characteristics, three shale samples from the 10th cyclothem of the Eq3 (Eq34–10 cyclothem) inter-salt shale were selected to acquire 2D and 3D grayscale images by modular automated processing system (MAPS) and X-ray micro-computed tomography (Micro-CT), respectively. The color map of the inlaid characteristics of mineral aggregates was established by Quantitative Evaluation of Minerals by Scanning Electron Microscopy (QEMSCAN), and different mineral types in the grayscale image were determined. After that, the digital core technology was used to reconstruct the core in 3D, and the maximum sphere method was used to extract the pore network model, so as to realize the quantification of micron pore throats and the 3D visualization of inter-shale samples. Meanwhile, in order to compare the fractal characteristics of the pores of the samples, the two-dimensional and three-dimensional fractal dimensions of the three cores were calculated by combining the digital core technique with fractal theory. The study yielded several notable results: the pore structure of inter-salt shale reservoirs is complex and multi-scale, and the CT scanning digital core technology can effectively realize 3D visualization of rock microstructure without damage. The pore types of rock samples are mainly intergranular pores, interparticle pores, and dissolved pores, and the minerals are mainly dolomite, calcite, and glauberite. The micron pore throat radius of the rock sample is 0.5–13.9 μm, the distribution of coordination number is mainly in the range of 1–4, and the shape of the pore throat is mainly triangular and square. The pore space of inter-salt shale has suitable fractal characteristics, and the three-dimensional fractal dimension of the three cores is in the range of 2.41–2.49. In sum, this work used digital core technology to study the microscopic pore structure of inter-salt shale oil, establishing a basis for further understanding of the seepage characteristics and exploration and development of shale oil.

Published: July 2022

Alpha thalassemia is an autosomal recessive disorder caused by large deletions and/or point mutations in the α- globin genes. Hemoglobin H (Hb H) disease is most frequently due to deletion of three of the four α globin genes associated with variable clinical severity depending on the genotype. There are few reports on Hb H disease in Indians where genotyping has been done and we have reviewed the molecular and clinical heterogeneity of these cases. An electronic search for relevant articles was conducted using two journal databases, i.e., PubMed and Science Direct using the key words “Hb H Disease”, “Hemoglobin H”, “α-thalassemia”, “mutations”, “molecular heterogeneity”, “case reports” and “India”. This review was performed based on preferred reporting items for the systematic review and meta-analysis protocols (PRISMA-P) guidelines. The molecular spectrum of Hb H disease in Indians includes the most common [-α3.7, -α4.2, --SA, Poly A (AATAAA→AATA--), Hb Sallanches], rare [--SEA, --MED, IVS 1nt 1 (G→A), Hb Koya Dora, Hb Sun Prairie], very rare [Hb Iberia, Hb Seal Rock, Hb Zürich-Albisrieden] and novel [Codon 76 (+T) and --Kol] α-globin gene mutations inherited largely as compound heterozygotes with considerable clinical variability. The molecular diagnosis of Hb H disease is important for genetic counseling and management.

False flax is a valuable and irreplaceable oilseed crop. The oil obtained from false flax plants can be compared with flax oil in terms of its useful properties. However, false flax oil has better preservation and has better taste qualities. It is very profitable to use false flax for the production of feed. After the false flax undergoes heat treatment, the remaining press-cake is used as feed for poultry and livestock. Thus, 100 kg of press-cake and 17 kg of protein contain 115 feed units. The purpose of the research was to determine the influence of elements of cultivation technology on the yield of spring false flax on seeds under the conditions of the Ryazan region. The Ryazan region is characterized by a temperate continental climate with warm summers and moderately cold winters with stable snow cover and well-defined, but less long transitional seasons such as spring and autumn. Under the conditions of the Ryazan region the most effective technological techniques (sowing period, seeding rate, use of plant growth regulators) have been developed and experimentally substantiated in order to increase production and improve the quality characteristics of oilseed false flax seeds. The relationship between the individual elements of the crop structure and the yield of spring false flax, as well as weather conditions, is revealed. It is established that the cultivation of spring false flax with a seeding rate of 7 million pieces germinating seeds/ha, was the most cost-effective, where the level of profitability did not fall below 70,3 %. At the same time, the level of profitability was higher in the first sowing period than in the second, which is associated with a higher yield (1,11–1,25 t/ha) and the quality of the products obtained.

Authors: Ibrahim Hisham R. , Ahmed Ahmed S. , Komeda Airi , Miyata Takeshi
Published: July 2022

Background: Camel milk has been recognized for its health benefits since ancient times and has recently been attracting increasing attention as a form of medical treatment for diverse human diseases. Studies on the health benefits of camel milk attributed its medicinal effects to nutritional status, but the molecular mechanisms of proteins involved in such effects remain unknown. Objectives: The aim of this study was to explore the anticancer properties of camel milk proteins (CMPs). Methods: CMPs were fractionated into camel casein proteins (CCPs) and camel whey proteins (CWPs). The CWP exhibited the most potent anticancer activity against colon (HCT-116) and breast (MCF-7) cancer cells. The CWP was further fractionated into cationic and anionic proteins using HiTrap cationic (SP-XL) and anionic (QFF) exchange columns. Results: QFF-bound proteins (QFF-B) exhibited the strongest anticancer activities against both cancer cells. QFF-B proteins produced three peaks (P1~P3) on RP-HPLC, whereas P3 showed superior anticancer activity. The cytotoxic effects of CWP and QFF-B proteins are associated with increased production of intracellular ROS and subsequent apoptosis in both cancer cells. MALDI-TOF-MS identified lactophorin, glycation-dependent cell adhesion molecule1 (GlyCAM-1), and its three driven fragments as dominant peptides in QFF-B, while RP-HPLC-P3 contained two of them with molecular masses of 8080.3 and 9395.6 Da. The two peptides, both derived from the C-terminal of lactophorin, were the most representative peptides in the most active protein fractions (QFF-B and RP-HPLC-P3). Conclusion: The results highlight for the first time that lactophorin is the major anti-cancer ingredient in camel milk and its unique C-terminal peptides present potential candidacy as anticancer agents in nutraceutical and pharmacological applications.

Published: July 2022

Background: Genistein is an isoflavone that has been reported to have various anti-cancer properties. Objectives: This study aimed to reveal whether or not the anti-cancer properties of genistein in AGS gastric cancer cell line were mediated through caspase-3 enzyme. Methods: AGS gastric cancer cells were treated with different concentrations of genistein for 12, 24, and 48 hours and, then, the viability of the cells and IC50 were determined. To determine the effect of genistein on AGS cell migration potency, the wound healing assay was performed. The genistein-induced apoptosis in AGS gastric cells was evaluated by flow cytometry. Caspase-3 gene (CASP3) expression level and its enzyme activity level were determined by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and colorimetric techniques, respectively. Results: The IC50 value was calculated as 70 µM concentration for 24 hours of incubation with genistein. Genistein significantly reduced AGS cell migration compared to the untreated control cells (P<0.001). Genistein increased the early and late apoptosis of the cells (P<0.001) and upregulated the caspase-3 gene expression (P<0.001), but did not significantly enhance the caspase-3 enzyme activity in treated cells. Conclusion: Genistein exhibited anti-cancer effects on AGS cells to some extent by reducing cellular migration, increasing apoptosis, and upregulating CASP3 gene expression; however, it did not alter the caspse-3 activity. Therefore, it was recommended that more studies should be carried out to delineate the role of caspase-3 in health benefits attributed to the genistein.

Authors: Avogbe Patrice Hodonou , Sanni Ambaliou
Published: July 2022

Background: An elevated level of uric acid (UA), also known as hyperuricemia (HUA), contributes to the occurrence of cardiovascular diseases (CVDs). However, epidemiolocal features of HUA in populations of Benin are rare. Objectives: We identified clinical and metabolic factors associated with HUA in taxi-motorbike drivers (TMDs) of Cotonou. Methods: A total of 134 participants with a mean age of 39.3 years were analyzed using a retrospective cross-sectional study design. Data from a self-administered questionnaire and biochemical markers including, plasma UA, glucose, insulin, creatinine, and lipids were obtained from each participant. HUA was defined as plasma UA greater than 416 μmol/L. Insulin resistance (IR) was determined using the homeostatic model assessment (HOMA). Logistic regression analysis was performed to determine the association of various risk factors with HUA. Odds ratio (OR) and 95% confidence interval (CI) were calculated for HUA. Results: The overall prevalence of HUA was 19.4% (95% CI: 12.7-26.1) in TMDs. Multivariable logistic regression showed that IR (OR=3.60, 95% CI: 1.27-10.22, P=0.02), hypertension (OR=2.75, 95% CI: 1.00- 7.54, P=0.05), and triglycerides (TG; OR=4.25, 95% CI: 1.39-12.98, P=0.01) were risk factors for HUA. Furthermore, creatinine was inversely associated with HUA (OR=0.62, 95% CI: 0.41-0.94, P=0.02). Conclusion: HUA was found in 19.4% of the patients. In addition, hypertension, IR, creatinine, and TG levels were independently associated with HUA in TMDs. Therefore, the monitoring of these markers may help prevent HUA.

Authors: Maghsoodlou Mona , Fozouni Leila , Salehnia Sammak Ali
Published: July 2022

Background: Dental caries is one of the most common causes threatening human health globally. Sortase A (Srt A) as a transpeptidase, mediates the attachment of the Streptococcus mutans cell wall to dental surfaces by biofilm formation. Due to the development of multidrug-resistance bacteria, attempting to discover growth inhibitors is logical and promising. Objectives: The current study aimed at the experimental and docking-based virtual screening of myricetinlike inhibitors for the inhibition of Srt A enzyme in S. mutans isolates. Methods: Sixty-three S. mutans were isolated from pupils based on cultural, morphological, and biochemical characteristics (N=150). After identifying the srtA gene using the polymerase chain reaction (PCR) with specific primers, a broth microdilution test was conducted according to CLSI-2020 criteria to determine the minimum inhibitory concentration (MIC) of myricetin. The in silico exploration of Srt A inhibitors was performed using AutoDock 4.2.6. Results: The frequency of S. mutans isolates containing the srtA gene was 87.3% of which, fifty isolates (79.4%) were categorized as susceptible to myricetin (MIC,≤16 μg/mL). Of 20 ligands having a high degree of similarity with myricetin, the best docking results were related to ligand 2. Conclusion: It was concluded that myricetin has an inhibitory effect on oral bacteria in vitro, and ligand 2 had the most negative binding energy (-4.66 kcal/mol) and favorably interacts with the key amino acid residues at the active site of Srt A. Accordingly, this ligand can be utilized as a lead compound for further studies to discover novel inhibitors targeting Srt A in S. mutans.

Authors: Nga Cao Phuong
Published: July 2022

To reach a better form of new product development performances along with customer participation, this study has examined the benefits of customer participation, which leads to customer satisfaction based on three attributes of Kano's model. Although the prior studies have stated that customer participation in the new product development is a double-edged sword strategy, this study has shown that cooperating with customers is an easy path to get to the customer satisfaction. We also assume that this satisfaction has led to a greater willingness of customers to buy and use products that improve financial performance and as customer acceptance increases, the new product market will grow dramatically. Obtained data collected from 567 holding companies and 422 customers indicates that customer participation leads to the customer satisfaction and it has a positive impact on new product development financial performance and new product market. The results of this article provide specific managerial guidelines for managing customer participation to improve radical new product innovation.

Published: July 2022

The rapid inflation process is the most important stage in the whole working process of rapid deployment of aerostat.
However, it is difficult to reveal its mechanical mechanism by existing experimental and numerical methods and
reasonably explain the damage and helium leakage during the inflation process. An air-launched balloon for rapid
deployment was designed and manufactured, and the related ground steady inflation experiment was carried out in this
work. Then, the rapid inflation process of the folded balloon was studied by using the Simplified Arbitrary Lagrangian-
Eulerian (SALE) method. Here, the folded balloon model was obtained by the reverse folding method. The structure and
flow field were described by Lagrangian elements, and the coupling between them was obtained by a contact algorithm.
The numerical results were in good agreement with the experimental results. The numerical method in this work could
obtain abundant information on the structure and flow field which couldn’t be obtained by the experimental method. The
change law of structure and flow field was obtained and the failure mechanism in the destructive experiment was
explained. The numerical method proposed in this work could provide a reference for the material selection, gas source
selection and structure optimization of the rapid deployment aerostat system.

Published: July 2022

Alternative assessment is traditionally viewed as a method of evaluating students’ performance and as a formal testing method of gauging students’ performance. However, in the wake of the Covid-19 pandemic, alternative assessment has influenced the way students learn through collaborative peer learning. This exploratory case study design integrated e-portfolio and oral presentation as an alternative assessment in measuring students’ learning performance and concur that alternative assessment provides a pathway to learning through collaborative learning in writing. The sample comprised 25 students who were from a tertiary institution undertaking an English course. By creating an e-portfolio in Google classrooms, students uploaded their written evaluative commentary of the tasks and uploaded their video recording of their oral presentations, in addition to providing their reflection and feedback on their learning experience while undergoing the alternative assessment. The e-portfolio was employed as an alternative assessment in order to measure students’ writing skills by facilitating, compiling and archiving their work using an analytical rubric. The tasks were tailored to equip students with reasoning and critical thinking skills along with key toolkits in producing evaluative commentary and group oral presentation. The quantitative data in the form of students raw score and the qualitative data from students’ written reflection and feedback were thematically. The findings of the study revealed five themes (boost confidence, enhanced communication skills, encouraged collaborative learning and teamwork and novel learning experience) that support its role as an innovating learning tool among second language learners of English in enhancing their writing skills. Additionally, students were able to explore their learning by making connections and thinking critically through collaborative learning tasks. The study concludes that e-portfolio as an alternative assessment could potentially lead to deep learning when tasks are effectively integrated in multi-layers to promote learning.

Published: July 2022

Psychological distress referred to an emotional suffering state characterized by depression such as lost interest and hopelessness and anxiety symptoms such as felt tension and restlessness. Parents of children with special needs were likely to be at a higher risk of psychological distress since they might experience many challenges to raise the children. t The long-term issues of children with physical-motor disorders and mental retardation and the need for continuous treatment, these parents would experience high levels of stress and frequently became depressed, frustrated, and disappointed with their children development This study aimed to identify the severity of psychological distress of the parents among special needs children and the relationship between demographic variables and parents' psychological distress among special needs children. A total of 224 parents with special needs children in Terengganu were involved. The psychological distress of parents was measured by using Kessler Psychological Distress Scale (K10). Results indicated 36.6% of parents were having severe distress, 21% were experiencing moderate distress and, 21.9% had mild distress. Parent’s job status had indicated a positive significant correlation between severity of psychological distress (r = 0.148, N = 224, p < 0.05). The other variables such as parent's age, parent’s gender, child’s age and diagnosis, parent’s marital status, and parent's education level had shown no significant correlation between the severities of psychological distress. In conclusion, most parents were having psychological distress. Nevertheless, only the job status had demonstrated an impact on the psychological distress of parents.

Published: July 2022

The practice of reading the Qur'an is an act of worship and is required in Islam. However, students nowadays disdain the learning of the Qur'an and focus more on the academic besides being less fluent in reading the Qur'an. Thus, this study examines the practice and awareness of Muadzam Shah Polytechnic (PMS) students on the importance of reading the Quran in daily life. This study aims to look at the demographic factors and its relation to the practice and awareness of reading the Qur'an. The method used in this study is descriptive research using questionnaires. A total of 239 respondents were involved comprising final semester students from each department. The analysis of the study was done using IBM SPSS software (Statistical Packages for the Social Sciences) version 24.0. The findings of the study through T-test showed that there was no significant difference in the practice and awareness based on students’ gender and study program. However, Pearson correlation analysis showed that there was a significant positive relationship between the practice of reading the Quran and the status of completion of the Quran. The results showed that the practice and awareness of reading the Quran among PMS students is at a high level.

This article is a continuation of the article [1]. It details the features of C4I [2] systems and the main problems occurring in their development. The article focuses on mathematical methods and rationales for their use. The sequence in which the material is given is in line with stages of the complex system software development, which include the formation of software structure, the structural analysis and the evaluation of success analysis. At the stage of forming the model structure the components are decomposed and the numerical evaluation of components connection is carried out. The mathematical apparatus of Markov chains is used to form a matrix that describes the connection between software components. The structural analysis stage provides clustering of software components and functional analysis, which reveals the feedback effect of the formed clusters of software components. The evaluation of success analysis provides the calculation of development success using a decision tree.

Throughout the life cycle of a product, a large amount of information is accumulated, the management of which is an extremely important and complex task. This task is solved by means of project data management systems PDM / PLM-systems (Product Data Management / Product Lifecycle Management). These systems provide an access to data on the product by various attributes and navigation based on its hierarchical structure. They also maintain information links between the product components and their describing documentation. The article discusses the challenges of modern enterprises of the aviation instrument-making industry, namely the data transfer between ECAD systems (electronic computer-aided design) and PDM/PLM systems. Database integration options are described using various connectors (Directum, Solidworks, ATK BIView, net, bom). The article analyses a functionality of existing ECAD systems for integration with PDM/PLM systems. A technique for integrating ECAD with PDM based on data import in bom or net-file format was developed.

Some parameters of many objects in practical situations are quasi-periodic, or there is a noticeable repeatability with random variations. Such parameters can be represented by random quasiperiodic processes, for example speech signals, aircraft engine noise and vibration, etc. From time to time, against the background of this process, special structures (signals) may appear that arise due to the influence of internal or external factors on the object, for example, impacts of external objects. In this article an autoregressive model is used to represent quasi-periodic processes. It is assumed that the detected signals interact additively with the background (process) and have a known shape. The detection algorithm is based on the classical likelihood ratio. In this case, the statistics of the decision rule is represented through the compensation of the background ‘to the point’, that is, through the subtraction from the observation at the point of its forecast for all other observations. The parameters of the background model may be unknown; therefore, an adaptive pseudogradient algorithm for optimizing the parameters of the background compensator is applied. In the case of homogeneous processes, the compensator converges to the optimal one, constructed with known background parameters, and in the case of inhomogeneity, compensation and detection are carried out that are close to optimal. The results of statistical tests of the developed algorithm are presented.

The conditions of combustion reactions determine the nature of combustion and its results. An uninterrupted operation of combustion devices is required to ensure a complete combustion of fuel by the influence of heat mass transfer and aerodynamics on the ongoing chemical reactions since power plants are the main sources of hazardous emissions. Therefore, the study of furnace process efficiency by means of mathematical modeling is getting more significant. This study allows to determine the dynamic performance of a power plant, to investigate the effectiveness of security measures, the use of combined fuels and low-emission burners. Based on the review of works on the research topic, it can be concluded that the study of furnace processes requires the use of CFD modeling. The article considers a mathematical model and methodology for the numerical study of the methane-air mixture combustion in STAR-CCM+, and describes the choice of mesh and combustion model. The results of numerical study with the influence of recirculation degree changing the ratio of combustion gas from 0 to 15% to reduce the hazardous emissions are presented. Based on the results of simulation, a technical solution was developed to improve the effectiveness of fuel combustion in power plants, and its scheme is presented. The article is intended for graduate and doctoral students interested in numerical study and development of methods for suppressing the formation of thermal nitrogen oxides in the combustion products of boilers of thermal power plants.

Published: July 2022

Traditional survey methods for finding surface re- sistivity are time consuming and labor intensive. Very few studies have focused on finding the resistivity / conductivity using remote sensing data and deep learning techniques. In this line of work, we assessed the correlation between surface resistivity and Synthetic Aperture Radar (SAR) by applying various deep learning methods and tested our hypothesis in the Coso Geothermal Area, USA. For detecting the resistivity, L- band full polarimetric SAR data acquired by UAVSAR were used, and MT (Magnetotellurics) inverted resistivity data of the area were used as the ground truth. We conducted experiments to compare various deep learning architectures, and suggest the use of Dual Input UNet (DI-UNet) architecture. DI-UNet uses a deep learning architecture to predict the resistivity using full polarimetric SAR data by promising a quick survey addition to the traditional method. Our proposed approach accomplished improved outcomes for the mapping of MT resistivity from SAR data.
Polynomial Approximation of Power System Eigenvalues for Fast Small Signal Stability Analysis
Authors: Khodaei Farhad
Published: July 2022

In power system dynamic analysis, computation of eigenvalues of state equations for various active dispatched powers is important. This concept provides a better understanding of the system dynamic behavior. In this paper, an approximate equation extraction technique is proposed for fast computation of real-part of the most critical eigenvalue of New England 39-bus power system. Simulation by using MATLAB PSAT toolbox is carried out as a source of the initial data for finding a proper approximate function and also its verification. As an application example, the obtained polynomial approximate function has been applied to small signal stability constrained optimal power flow by using GAMS optimization package. The obtained polynomial function can be used with various optimization criteria in the valid interval of the approximation. Also this polynomial function can be re-used when generation cost functions are changed, without need for a new dynamic analysis. All of the dynamic analyses by PSAT toolbox are performed by using automatic intermediate codes cooperating with functions and variables of the PSAT toolbox and handy registration of numbers is avoided.
