Authors: Wang Li , Ding Kun , Hou Chunguo , Zou Zhiqiang , Qin Song
Published: December 2019

Background: Severe fever with thrombocytopenia syndrome (SFTS) is a severe systemic virus infectious disease usually having multi-organ dysfunction which resembles sepsis.Methods: A total of 321 patients with laboratory-confirmed SFTS from May 2013 to July 2017 were retrospectively analysed. Demographic and clinical characteristics, calculated quick sequential organ failure assessment (qSOFA) score and systemic inflammatory response syndrome (SIRS) criteria for survivors and nonsurvivors were compared. Independent risk factors associated with in-hospital mortality were obtained using multivariable logistic regression analysis. Risk score models containing different risk factors for mortality in stratified patients were established whose predictive values were evaluated using area under ROC curve (AUC).Results: Of 321 patients, 87 died (27.1%). Age (p<0.001) and percentage numbers of patients with qSOFA≥2 and SIRS≥2 (p<0.0001) were profoundly greater in nonsurvivors than in survivors. Age, qSOFA, SIRS score and aspartate aminotransferase (AST) were independent risk factors for mortality for all patients. And qSOFA score was the only common risk factor in all patients, those of age≥60 years and those enrolled in intensive care unit (ICU). A risk score model containing all these risk factors (Model1) has high predictive value for in-hospital mortality in these three groups with AUCs (95% CI): 0.919 (0.883-0.946), 0.929 (0.862-0.944) and 0.815 (0.710-0.894), respectively. Kaplan-Meier survival analysis showed a strong difference between high-risk and low-risk groups at a cutoff value > 9.22 (log-rank c2 = 126.3, p <0.0001) Conclusions: qSOFA and risk models containing qSOFA have high predictive validity for SFTS in-hospital mortality.

Published: December 2019

Background: Post-neurosurgical bacterial meningitis (PNBM) is a severe complication with high morbidity and mortality. Rapid and accurate diagnosis of PNBM is difficult. Therefore, it is necessary to find more reliable markers to assist the diagnosis. This study aims to evaluate the predictive value of cerebrospinal fluid (CSF) lactate for PNBM diagnosis and treatment efficacy.Methods: Total 105 cases were enrolled in patients with clinically suspected PNBM who underwent neurosurgeries during October 2015 to December 2016. CSF lactate as well as CSF routine and biochemistry test was measured. Receivers operating characteristic (ROC) curve analysis was used to evaluate the diagnostie power of CSF lactate for PNBM. To assess the predictive value of CSF lactate for treatment efficacy, a linear regression was used and tendency diagrams of CSF lactate and glucose for each patient were drawn.Results: Fifty-four of 105 patients were diagnosed with PNBM. CSF lactate level was significantly higher in PNBM than in non-PNBM patients (p < 0.001). The ROC curve analysis showed a great diagnostic power of CSF lactate for PNBM, and the cut-off value was 4.15 mmol/L (AUC = 0.92, sensitivity, 92.6%; specificity, 74.5%). The combination of CSF lactate and glucose showed better diagnostic efficacy (AUC = 0.97, sensitivity, 94.4%; specificity, 90.2%). The linear regression showed thatΔCSF lactate inversely correlated with ΔCSF glucose and directly correlated with ΔCSF leucocyte (both p < 0.001). The tendency diagrams showed CSF lactate a better predictor for PNBM treatment efficacy than CSF glucose.Conclusion: Our study showed CSF lactate had an excellent discriminatory power in distinguishing between PNBM and non-PNBM. The combination of CSF lactate and glucose had a better diagnostic accuracy than other CSF parameters alone. CSF lactate was a reliable predictor of treatment efficacy in PNBM patients.

Published: December 2019

Background: China launched a new round of National Malaria Eradication Program (NMEP) in 2010 that sets the goal to eliminate malaria by 2020, while it has been challenged by the large-scale frequent population migration. To assess the influence of geographic mobility of population on the epidemiology of malaria, we conducted a comprehensive study about the care-seeking behavior among malaria patients. Methods: The malaria cases were identified within a national database from the National Health Commission of the People’s Republic of China. All health institutions and facilities reported malaria patient records during the period from January 2014 to December 2016. Overall 1633 malaria patients were selected in six provinces located in eastern, central and western China that saw most severe malaria epidemic using stratified sampling. Descriptive statistical analysis was used to investigate the distribution of malaria patients in various medical institutions, and the chi-square test was used to compare the cross-regional visit rates of different types of hospitals. Colored maps were drawn to visualize the spatial distribution of hospitals and spatial flow of malaria patients by using the ArcGIS software. Results: The proportions of malaria patients who sought medical care in general hospitals, township hospitals, and professional public health institutions were 81.7%, 14.7% and 3.6%, respectively. For those who visited hospitals, the percentages who chose provincial, prefecture-level and county-level hospitals for malaria treatment were 17.4%, 60.5% and 22.1%, correspondingly; the proportions of malaria patients who sought medical care in tertiary hospitals, secondary hospitals, and primary hospitals were 59.8%, 39.9% and 0.3%, respectively. Moreover, the proportions of inter-provincial, inter-city and inter-county patients were 3.9%, 82.4% and 80.2%, respectively. In addition, we also found that the percentage of malaria patients who sought treatment in designated hospitals was high. Conclusion: With the implementation of National Malaria Control Program (NMCP), malaria patients tended to seek medical care in designate tertiary hospitals, and slightly more than half of patients could be treated in health institutions and facilities in prefectural area. In the post-stage of malaria elimination, it is necessary to establish prompt response grassroots hospitals to refer malaria patients to designated malaria treatment hospitals.

Published: December 2019

Background: The vaginal microbiome has been widely investigated because of its utility in the diagnosis of vaginitis and its connection to various conditions. However, its relationship with impaired ovarian function and the influence of environmental pollutants have not been evaluated. Here, we conducted a next-generation sequencing study of the vaginal microbiome in young females with normal and decreased ovarian function and analyzed its correlation with various environmental pollutants. Methods: Vaginal swabs were collected from 92 individuals (22 with impaired ovarian function and 70 with normal function), and the vaginal microbiome was analyzed using next-generation sequencing. The 16S rDNA sequences were assembled by Fast Length Adjustment of SHort reads (FLASH) and clustered by Operational Taxonomic Units (OTUs). Diversity analysis was performed using Quantitative Insights Into Microbial Ecology (QIIME). Laboratory findings, including hormonal status were measured. Results: Most characteristics of the two groups were similar, except that the impaired function group showed lower AMH and higher FSH (p < 0.01 and p = 0.04, respectively). Among the most abundant taxa, several species differed; however, only two species showed significant differences: Propionibacterium acnes and Prevotella copri. The heat map did not show significant differences between the groups. Canonical correlation analysis revealed that more environmental pollutants were related to changes in the vaginal microbiome in the impaired ovarian function group than in the normal group. Conclusion: The vaginal microbiomes in young women with decreased ovarian function tended to be more sensitive to various environmental pollutants, especially volatile organic compounds (VOCs). Therefore, females with impaired ovarian function could be more vulnerable to VOCs.

Published: December 2019

BackgroundThe association between environmental factors and asthma has attracted much attention. Numerous studies have focused on the effects of air pollution or meteorological factors, but the synergistic effects and regional heterogeneity remain unclear. MethodsBetween 2014 and 2015, 8,563 hospital admissions in 2014 and 7,804 hospital admissions in 2015 due to asthma were collected from 14 regions in Guangxi, China. First, we performed a Spearman correlation coefficient model as the single factor analysis to estimate correlation between environmental factors and asthma hospitalization rates in multiple regions. Second, Generalized Additive Model (GAM) was used to analyze the synergistic effects of environmental factors on asthma hospitalization rates in 14 regions, respectively.ResultsThe results indicated that asthma hospitalization rates were high in spring and autumn. There were all nonlinear relationships between air pollutants, meteorological factors and asthma hospitalization rates, and the relationships were different from region to region. According to the single factor analysis, asthma hospitalizations were related to the daily temperature, daily range of temperature, CO, NO2, and PM2.5 in multiple regions. According to the result of synergistic effects analysis, the adjusted R-square was high in Beihai and Nanning, with values of 0.292 and 0.207, which meant that environmental factors were powerful in explaining changes of asthma hospitalization rates in Beihai and Nanning.ConclusionDaily range of temperature is an important factor impact on asthma, which should be considered in the analysis of environmental factors impact on asthma. It is suggested that the relationship between asthma and risk factors in different regions deserves additional study. Governments should develop targeted protective measures for asthma in different regions.

Authors: Sakhanda Ivanna , Orlov Oleksii
Published: December 2019

The aim. To substantiate the effectiveness of the use of VAC-therapy in the treatment of wounds in patients with diabetic foot syndrome. Materials and methods. The patient with a complicated form of diabetic foot syndrome was examined. The monitoring of the course of the wound process is supplemented by clinical, cytological, microbiological and morphological criteria. In the treatment of patients we used vacuum therapy apparatus. Vacuum wound therapy was performed in negative pressure regimens in the range of 80–125 mm Hg. Results. In the pattern of morbidity in economically developed countries, diabetes mellitus (DM) occupies one of the first places. Its prevalence is 1.5–6 %. The number of patients with diabetes in Ukraine is likely to reach 14 million by 2020. Lesions of the lower extremities of different genesis occur in 30–80 % of people with impaired carbohydrate metabolism. Most often, these lesions are complicated by the development of chronic peptic ulcer defects, which, when untimely diagnosed and inadequate treatment, leads to amputation of the affected limb. Even when radical surgery is avoided, the long and costly treatment of trophic disorders of the soft tissues of the feet and legs leads to huge costs of both material resources and time for medical staff. In 15 % of patients with DM, trophic ulcers of the lower extremities are diagnosed. Recent studies have focused on such important aspects of the study of this issue as the early diagnosis of soft tissue lesions in individuals with DM, the development of treatment aimed at preventing amputations, facilitating the further rehabilitation of patients. Vacuum therapy is one of the new methods of treating wound defects, including in patients with diabetic foot syndrome. Topical application of vacuum therapy has already become an integral therapeutic option for wound debridement in patients with diabetic foot syndrome. However, when applying the classic vacuum therapy technique, these patients have the problem of delaying the outflow of tissue exudate and lysis detritus to the vacuum system. Conclusions. Optimization of the technique of the influence of negative pressure on the wound by applying forced drainage with irrigation of the wound with an antiseptic can maintain a constantly high concentration of antimicrobial agent in the wound, increase the speed of wound dialysis and prevent clogging of pores of the sponge and the bacterial colonies in it. The application of this technique avoids high amputation, accelerates the time of wound healing, and retains the supporting function of the lower extremity.
The policy-led sustainability and financial performance linkage in the banking sector: case of Bangladesh
Authors: Parvez Ahmed Samiul , Uddin Ahmed Sarwar , Fahad Noor Mohammad , Ahmed Zaima , Karmaker Uttam
Published: December 2019

Researchers in developed countries argue that banks should be free to decide about their sustainability initiatives without the interference from regulators. However, researchers in developing countries tend to think differently. This study aimed to focus on this argument by examining the linkage between sustainability and financial performance (SFP) aided through regulatory policy guidelines. In doing so, a comparative study was conducted between 2012 and 2018 to compare the pre- and post-status of SFP due to implementation of policy measures. Environmental, social and governance (ESG) scores were calculated and related with financial performance (return on assets) through regression analysis. The sample data includes 30 private commercial banks (PCBs) in Bangladesh. The analysis of the data shows that during these years, the overall sustainability performance, i.e., environmental, social and governance scores of the banks increased by 33 percent. However, the transformation of this performance into better financial performance could not been established even when age and size were taken into account. The current turbulent state of the banking sector due to growing non-performing loan has been identified as the single most influential factor for this neutral result. Research findings suggest that policy guideline initiatives do have a positive impact on bank sustainability. However, exogenous factors, such as political interference, may appease, deviate and prolong its impact on financial performance. This work will enhance the understanding of academics and policy-makers about the feasibility and impact of the policy-led sustainability model in the banking sector, particularly in developing countries.
Detection of human fecal pollution in environmental waters using human mitochondrial DNA and correlation with general and human-associated fecal genetic markers
Authors: Tanvir Pasha A. B. M. , Hinojosa Jessica , Phan Duc , Lopez Adrianne , Kapoor Vikram
Published: December 2019

Human mitochondrial DNA (mtDNA) genetic markers are abundant in sewage and highly human-specific, suggesting a great potential for the environmental application as human fecal pollution indicators. Limited data are available on the occurrence and co-occurrence of human mtDNA with fecal bacterial markers in surface waters, and how the abundance of these markers is influenced by rain events. A 1-year sampling study was conducted in a suburban watershed impacted by human sewage contamination to evaluate the performance of a human mtDNA-based marker along with the bacterial genetic markers for human-associated Bacteroidales (BacHum and HF183) and Escherichia coli. Additionally, the human mtDNA-based assay was correlated with rain events and other markers. The mtDNA marker was detected in 92% of samples (n = 140) with a mean concentration of 2.96 log10 copies/100 ml throughout the study period. Human mtDNA was detected with greater abundance than human-associated Bacteroidales that could be attributed to differences in the decay of these markers in the environment. The abundance of all markers was positively correlated with rain events, and human mtDNA abundance was significantly correlated with various bacterial markers. In general, these results should support future risk assessment for impacted watersheds, particularly those affected by human fecal pollution, by evaluating the performance of these markers during rain events.

Authors: Mann Sonia , Sharma Ankita , Sarkar Ashish , Kharb Rupsi , Malhotra Rajesh , Datta Barun , Gupta Rajinder K. , Biswas Sagarika
Published: December 2019

Background:

Rheumatoid Arthritis (RA) is an autoimmune, systemic disease mainly affecting
joints. Presently, there is no specific treatment/ drug available for curing RA except few supportive
medicines. Therefore, the focus has been shifted to medicinal plants for the treatment of such diseases.
Choerospondias axillaris commonly known as Lupsi/Lapsi and has been reported to have several
properties for the treatment of various diseases.

Objective:

The present study has been conducted to explore the anti-inflammatory effects of Choerospondias
axillaris fruit extract on Synoviocytes (FLS) and Collagen-Induced Arthritis (CIA) rat model.

Methods:

Methanolic extract of the Choerospondias axillaris fruit was used for determining phytochemical,
antioxidant and anti-inflammatory properties. Antioxidant activity of Choerospondias axillaris
fruit was determined by free radicals scavenging assays and bioactive compounds were identified
via LC-MS/MS analysis. Anti-inflammatory effect was investigated in RA and Osteo Arthritis (OA)
primary cells and also in Collagen Induced Arthritis (CIA) rat models. Further, the medicinal properties
of anti-inflammatory bioactive compounds were supported by docking studies.

Results:

In-vitro and in-vivo studies showed significant decrease in the levels of inflammatory cytokines.
Docking analysis revealed that quercetin inhibits TNF-α having -9.1 kcal/mol binding energy
and 10.13 μM inhibitory constant. Quercetin also inhibits IL-6 having -6.6 kcal/mol binding energy
and 21.9 μM inhibitory constant.

Conclusion:

Observed results suggest that the underutilized fruit Choerospondias axillaris can be used
to reduce the inflammation of inflammatory diseases like RA.

Published: December 2019

Background:

Antibacterial resistance is a serious public health problem infecting millions in
the global population. Currently, there are few antimicrobials on the market against resistant bacterial
infections. Therefore, there is an urgent need for new therapeutic options against these strains.

Objective:

In this study, we synthesized and evaluated ten Bis(2-hydroxynaphthalene-1,4-dione) against
Gram-positive strains, including a hospital Methicillin-resistant (MRSA), and Gram-negative strains.

Method:

The compounds were prepared by condensation of aldehydes and lawsone in the presence of
different L-aminoacids as catalysts in very good yields. The compounds were submitted to antibacterial
analysis through disk diffusion and Minimal Inhibitory Concentration (MIC) assays.

Result:

L-aminoacids have been shown to be efficient catalysts in the preparation of Bis(2-
hydroxynaphthalene-1,4-dione) from 2-hydroxy-1,4-naphthoquinones and arylaldehydes in excellent
yields of up to 96%. The evaluation of the antibacterial profile against Gram-positive strains (Enterococcus
faecalis ATCC 29212, Staphylococcus aureus ATCC 25923, S. epidermidis ATCC 12228) also
including a hospital Methicillin-resistant S. aureus (MRSA) and Gram-negative strains (Escherichia coli
ATCC 25922, Pseudomonas aeruginosa ATCC 27853 and Klebsiella pneumoniae ATCC 4352), revealed
that seven compounds showed antibacterial activity within the Clinical and Laboratory Standards
Institute (CLSI) levels mainly against P. aeruginosa ATCC 27853 (MIC 8-128 µg/mL) and MRSA
(MIC 32-128 µg/mL). In addition, the in vitro toxicity showed all derivatives with no hemolytic effects
on healthy human erythrocytes. Furthermore, the derivatives showed satisfactory theoretical absorption,
distribution, metabolism, excretion, toxicity (ADMET) parameters, and a similar profile to antibiotics
currently in use. Finally, the in silico evaluation pointed to a structure-activity relationship related to
lipophilicity for these compounds. This feature may help them in acting against Gram-negative strains,
which present a rich lipid cell wall selective for several antibiotics.

Conclusion:

Our data showed the potential of this series for exploring new and more effective antibacterial
activities in vivo against other resistant bacteria.

Published: December 2019

Background:

In this paper, a two-pole 3 kW three-phase induction motor is taken as an
example to establish a two-dimensional finite element model. The correctness of the model is verified
by comparing the finite element calculation data with the experimental data.

Methods:

On this basis, the influence of electromagnetic characteristics of different shell materials
on the motor yoke saturation degree, loss, current and power factor are studied, it is determined
that the motor yoke saturation degree is the key factor affecting the power factor, current and loss
of the motor. The influence of different stator yoke thickness on the saturation degree of motor stator
yoke with the same shell material is further studied. The influences of motor stator yoke saturation
degree on motor current, loss and power factor are obtained when the stator yoke thickness is
different.

Results:

The optimum range of motor current, loss and power factor is obtained.

Conclusion:

Finally, by comparing the different shell materials to optimize the motor structure size, it
is determined that the motor stator yoke thickness can be reduced by using cast iron shell, and the motor
materials consumption can be saved to provide reference for motor optimization design.

Identification of the Facial Features of Patients With Cancer: A Deep Learning–Based Pilot Study (Preprint)
Authors: Liang Bin , Yang Na , He Guosheng , Huang Peng , Yang Yong
Published: December 2019

BACKGROUND

Cancer has become the second leading cause of death globally. Most cancer cases are due to genetic mutations, which affect metabolism and result in facial changes.

OBJECTIVE

In this study, we aimed to identify the facial features of patients with cancer using the deep learning technique.

METHODS

Images of faces of patients with cancer were collected to build the cancer face image data set. A face image data set of people without cancer was built by randomly selecting images from the publicly available MegaAge data set according to the sex and age distribution of the cancer face image data set. Each face image was preprocessed to obtain an upright centered face chip, following which the background was filtered out to exclude the effects of nonrelative factors. A residual neural network was constructed to classify cancer and noncancer cases. Transfer learning, minibatches, few epochs, L2 regulation, and random dropout training strategies were used to prevent overfitting. Moreover, guided gradient-weighted class activation mapping was used to reveal the relevant features.

RESULTS

A total of 8124 face images of patients with cancer (men: n=3851, 47.4%; women: n=4273, 52.6%) were collected from January 2018 to January 2019. The ages of the patients ranged from 1 year to 70 years (median age 52 years). The average faces of both male and female patients with cancer displayed more obvious facial adiposity than the average faces of people without cancer, which was supported by a landmark comparison. When testing the data set, the training process was terminated after 5 epochs. The area under the receiver operating characteristic curve was 0.94, and the accuracy rate was 0.82. The main relative feature of cancer cases was facial skin, while the relative features of noncancer cases were extracted from the complementary face region.

CONCLUSIONS

In this study, we built a face data set of patients with cancer and constructed a deep learning model to classify the faces of people with and those without cancer. We found that facial skin and adiposity were closely related to the presence of cancer.
A Scalable System for Passively Monitoring Oral Health Behaviors Using Electronic Toothbrushes in the Home Setting: Development and Feasibility Study (Preprint)
Authors: Shetty Vivek , Morrison Douglas , Belin Thomas , Hnat Timothy , Kumar Santosh
Published: December 2019

BACKGROUND

Dental disease (including dental caries and periodontal disease) is largely preventable and closely linked to inadequate oral health behaviors. Digital health technologies have great potential for unobtrusively monitoring brushing behaviors in home settings and promoting optimal oral self-care routines at scale.

OBJECTIVE

The aim of this study is to leverage the ubiquity of electronic toothbrushes and smartphones with the development of a Remote Oral Behaviors Assessment System (ROBAS) and evaluate its feasibility for passively tracking brushing behaviors in real-world settings.

METHODS

We developed ROBAS by linking inertial sensors contained within consumer electronic toothbrushes to a scalable software platform comprised of a smartphone app linked to a cloud platform. First, the criterion validity of ROBAS for accurately capturing brushing details was established in a laboratory setting. Next, real-world performance and usability were evaluated in a stratified community sample of 32 participants who used ROBAS daily for 1 month and maintained a diary of their brushing episodes. Semistructured interviews at baseline and exit captured the user experience. We used regression models and Bland-Altman analyses to assess the criterion validity, functionality, accuracy, and consistency of ROBAS.

RESULTS

Using a stopwatch as the criterion reference, ROBAS showed a mean absolute percent error (MAPE) of 1.8%, an estimated bias of 0.64 seconds that was not statistically distinguishable from zero (95% CI –0.93 to 2.22 seconds, SE 0.79), and a connection failure rate of 6.7% (95% CI 0.8%-22.1%, SE 4.6%). In real-world testing, ROBAS showed close agreement with the daily diary recordings of brushing episodes; estimated average discrepancies between the diary and ROBAS were 0.13 sessions per day (95% CI 0.01-0.26, SE 0.06), 8.0 seconds per brushing session (95% CI 1.4-14.7, SE 3.3), and 30 seconds of brushing per day (95% CI 9.3-50.1, SE 10.0). Retrospective self-reports produced substantially higher estimates of brushing frequency and duration compared to ROBAS measurements. Participants reported ROBAS was easy to use and expressed an interest in receiving ROBAS-delivered feedback on their brushing behaviors. Most participants were bothered by the use of an additional study phone, and some reported connectivity-related issues.

CONCLUSIONS

ROBAS has a high criterion validity for measuring oral health behaviors. It can accurately and reliably monitor brushing patterns in home settings for extended periods. Unobtrusive data collection through ROBAS sets the stage for automated coaching and optimization of oral self-care practices at the individual and population level.

Authors: Naguboina Vinay , Gudey Satish
Published: December 2019

In this work, a Three phase Transformerless Hybrid Series Active Power Filter
(THSeAF) based on Sliding Mode Control (SMC) is proposed to mitigate the
voltage and current distortions present in an electrical distribution
systems (EDS). A Sliding Mode Controller is designed by controlling the
parameters present on the load side as well as source side of the system.
Three separate voltage source converters (VSC) are used. The mod1elling of
the system is derived by considering a single-phase system by using state
space analysis. The frequency response characteristics have been derived for
the single-phase system and the stability of the system is studied. It is
observed that the system has good stability margins when the SMC is applied
at the source side compared to load side. Simulation results obtained in
PSCAD/EMTDC v4.6 have been observed for power quality issues like voltage
sags, voltage swells, voltage distortions, voltage unbalances and their
concurrent occurrence. The approach of stationary reference frame was used
for source side control and PQ theory is used for load side control. It is
observed that the proposed controller works well in obtaining a stable and
constant load voltage during these power quality issues. The difference in
settling time observed is around 4 ms for the load side and source side
control. The THD present in the load voltage is near about 1%. The SMC is
found to be robust in obtaining a constant load voltage with low THD and an
improved power factor.
Adaptive quantum-inspired evolutionary algorithm for optimizing power losses by dynamic load allocation on distributed generators
Authors: Manikanta Gopisetti , Mani Ashish , Singh Hemender , Chaturvedi Devendra
Published: December 2019

In this paper, an Adaptive Quantum-inspired Evolutionary Algorithm (AQiEA)
has been applied for minimizing the power losses in the distribution network
by suitable placement, sizing and subsequent allocation of load on
Distributed Generators (DG) for a varying load with a time horizon of
twentyfour hours. Many efforts have been reported in the literature to
minimize power losses. However, they have mostly used a fixed load, i.e.,
nonvarying load, whereas it is well known that load in distribution network
varies during the day. An investigation was undertaken to find the reduction
in power losses on a timevarying load. It has been found that the average
power losses for dynamic load allocation on DGs for every hour have a
maximum reduction in power loss as compared with other well-known cases in
the literature. Optimal location and size of DG is a difficult nonlinear,
non-differentiable combinatorial optimization problem. AQiEA is used to find
the appropriate location and capacity of DG for a varying load with a time
horizon of twenty-four hours to minimize the power losses. AQiEA doesn?t
require additional operators like local search and mutation to improve the
convergence rate and avoid the premature convergence. A Quantum Rotation
inspired Adaptive Crossover operator is used as a variation operator, which
is parameter free. The effectiveness of AQiEA is demonstrated on two test
bus systems viz., 33 bus system and 69 bus system, which are used as
benchmark problems for validating the proposed methodology as well as for
comparative testing amongst existing techniques. Wilcoxon signed rank test
is also used to demonstrate the effectiveness of AQiEA. The experimental
results show that AQiEA has better performance as compared to some existing
?state of art? techniques.

Published: December 2019

The state estimation of the voltage conversion process (with Kalman
filtering) in a solar power system is shown in this paper. Theoretical
principles of solar power systems are presented, along with the position and
working principles of a DC-DC boost converter in a solar power system.
Different modes of state estimation of the voltage conversion process are
shown, along with a detailed explanation of the Kalman filter appliance.
This approach can be applied to one of the maximum power point tracking
systems (MPPT). In the practical section of this paper, the implementation
of noise filtering concepts in a solar power system is shown, by using the
National Instruments LabVIEW programming suite. Processes that occur in this
type of system are simulated, and the basic principles of noise cancellation
are explained, in order to achieve optimal working conditions.
