A comparative analysis of the volatility nature of cryptocurrency and JSE market
Authors: Kaseke Forbes , Ramroop Shaun , Mwambi Henry
Published: October 2022

Despite the rapid growth of developing markets, aided by globalization, comparative studies of cryptocurrency and stock market volatility have focused on the developed markets and neglected developing ones. In this regard, this study compares cryptocurrency volatility with that of the Johannesburg Stock Exchange (JSE), a developing market. GARCH-type models are applied to daily log returns of Bitcoin, Ethereum, and the FTSE/JSE 4O in two ways. Firstly, the models are applied directly; secondly, structural breaks are tested and accounted for in the models. The sample period was from September 18, 2017, to May 27, 2021. The results show higher volatility and higher volatility persistence in cryptocurrency than in the JSE market. They also show that persistence is overestimated for cryptocurrencies when structural breaks are not accounted for. The opposite was true for the JSE.Moreover, the two cryptocurrencies were found to have close to identical volatility plots that differ from that of the JSE. High volatility periods of cryptocurrency also did not coincide with that of JSE and those of JSE did not coincide with the cryptocurrency ones. There is also evidence of an inverse leverage effect in cryptocurrency, which opposes the normal leverage effect of the JSE market.
Comparison Between Different Architectures of Multilayer Perceptron Networks for Blocking Rate Prediction in Mobile Phone Networks
Authors: Melo Gabriel da Silva , Santos Bruno Andre , Gomes Rogerio Martins
Published: October 2022

Blocking in mobile phone networks is a problem that consists of the refusal of the connection between a telephone device and a cell responsible for emitting the signal. The occurrence of blocking can indicate that a cell is close to congestion, leading to financial losses for telephone companies. This work developed three prediction systems using Multilayer Perceptron neural networks. Each system was modeled following different strategies: Direct, Recursive, and Direct Recursive, respectively. The training and test of the networks were carried out by using real data containing the history of blocking rates from a network of cells. The development stages consisted of analyzing the performance of each prediction system, varying the number of neurons in the hidden layers and the number of predicted steps from 1 (corresponding to 15 minutes ahead) to 20 (corresponding to 5 hours ahead). The system based on the Recursive strategy presented the lowest performance making predictions of short (15 minutes) and long (5 hours) terms with RMSE (Root Mean Squared Error) of approximately 13% and 40%, respectively, with a confidence interval between 27% and 29% considering all predictions. The systems based on the Direct and Direct Recursive strategies presented similar results, making predictions of short and long terms with RMSE of approximately 12% and 31%, respectively, with confidence intervals between 21% and 23% considering all predictions. Although the Direct and Direct Recursive systems obtained the lowest RMSE, the Direct Recursive is more advantageous as it requires fewer MLP networks. Consequently, it has simpler training and a lower computational cost.

Published: October 2022

Smart grids are an alternative to minimize environmental impacts, such as CO2 emissions, and improve the efficiency of electricity consumption in buildings. Power grids enable adequate management and monitoring of consumption because of the periodic storage of measurements and easy access to them. In this scenario, an accurate prediction is a challenging task. Forecasting of consumption series is a defiant problem because data present linear and nonlinear patterns, and a dependence on external variables may be observed. Hybrid models are an alternative to mapping both patterns, which have been widely used to forecast load time series. Autoregressive Integrated Moving Average (ARIMA) and Support Vector Regression (SVR) models are used for this purpose, to map the linear and nonlinear patterns of the series, respectively. In this paper, a nonlinear optimized hybrid system based on ARIMA, SVR, and Particle Swarm Optimization (PSO) is proposed. The system can be divided into three steps. First, the linear patterns are predicted by the statistical model ARIMA. Then, the residual series is modeled using an optimized SVR, in which the parameters are selected from the PSO. One particularity from the proposal is to incorporate the choice of the topology and the inertia coefficient into the system. Lastly, the predictions are combined using the SVR. The simulations were conducted using a real database from smart meters of a building in Taiwan. To evaluate the performance of the proposed method, four related approaches were implemented and compared: a single ARIMA, two linear combination systems, and one non-linear combination system. The results show a superiority of the proposed method in terms of the metrics Mean Squared Error (MSE), Mean Absolute Error (MAE), and Mean Absolute Percentage Error (MAPE).
Carbon capture utilization and storage (CCUS) – it’s happening now! However, are there still any challenges?
Authors: Halland Eva
Published: October 2022

These days we see a growing interest and more concrete project plans for CCUS in many European countries but with a pathway to “Net Zero”, we are fare from on-track! This definitely implies a stronger push for CCUS in Europe.

Although we can show 26 years of permanently stored CO2 in deep geological formations offshore Norway, heavily studied and monitored, there are still many questions about whether CCS is a safe and viable technology. Based on this experience and many years of research and development, we can conclude that this is a viable and safe technology.

We know that we have a large storage resources for CO2 on land and offshore in Europe, and we have large CO2 emissions that need to be captured. If CCUS is to achieve the economies of scale necessary to reduce costs and develop technology, cooperation is needed. Like other technologies that are expensive at the start, CO2capture needs to be more efficient and by that less expensive and we need an effort to speed up the mapping and characterization of safe CO2 storage capacity.

However, CCUS is the lowest cost, or only, option for many industries to decarbonize, and these industries will be fully exposed to the carbon price by 2023, so CCUS is essential to deliver large-scale and permanent removal of CO2.

To contribute to the development of technology for capture, transport, and storage of CO2, with the ambition of achieving a cost-effective solution, the Norwegian government decided in 2020 to develop a full-scale carbon capture and storage project, called Longship.

As a result of this decision, we now see that the next phase for CCS is already underway with a growing interest in new areas for CO2storage and more industrial demonstration projects for emission reductions.

On the Norwegian continental shelf, three licenses for offshore storage of CO2have been awarded in recent years, these involve 5 companies, and new license applications and new companies are on the way. These companies have presented clear projects involving the entire business chain.

We have the knowledge and the technology is ready, so why isn't the CCUS flying? Perhaps it is about setting clear political goals, transporting CO2across national borders, removing potential regulatory barriers and developing new business models. Easy? Let's talk about it and cooperate.

Published: October 2022

Following the 1918 influenza virus attack, which resulted in a worldwide pandemic, the world is again facing a similar situation as of March 2020, according to the World Health Organization (WHO). The discovery of a novel infectious agent from the Coronaviridae family was made possible by advancements in Medical Science and achievements in pharmaceutical research. SARS-CoV-2 is a member of the coronavirus family, a large and diverse group of viruses with a wide range of characteristics. This single-stranded RNA virus that infects humans and other animals has a single linear RNA segment and infects them in a positive-sense manner. The common cold is not the only sickness that coronaviruses may cause. They can also cause more dangerous infections like the Middle East respiratory syndrome (MERS), with a 34 percent mortality rate. Rapid sequencing by several organizations aided in identifying the virus's structure and function, determining the virus's immunogenicity in various populations, and developing effective prophylactic medicines for the virus. As of December 2020, the Centers for Disease Control and Prevention (CDC) announced that more than 150 vaccine candidates for COVID-19 were developing. Because of this, a total of 52 potential vaccination candidates are now being investigated in different phases. According to the WHO, nine vaccines have been approved and have extensive use from at least one regulatory authority, and five more are under evaluation.
Dietary Status of Women who Gave Birth with Congenital Anomalies in Bale Zone Hospitals, Southeast Ethiopia
Authors: Mekonnen Alemayehu Gonie , Kitila Tamiru Tesfaye , Amare Nakachew Sewnet
Published: October 2022

Objective:

Congenital anomalies (CAs) are structural or functional anomalies that develop during intrauterine life and are present at birth. There has been very little knowledge on various forms of CAs as well as dietary status of women who gave birth with CAs in Southeast Ethiopia. This study, therefore, examined the types of CAs diagnosed at birth as well as the dietary status of women who gave birth with CAs in Southeast Ethiopia.

Methods:

An institutional-based cross-sectional study was conducted in Bale zone hospitals, Southeast Ethiopia. All women who gave birth with any form of CAs were included in the study. All births were examined by either obstetricians or emergency obstetric surgeons. Data were entered into SPSS version 21 for analysis. Descriptive statistics were computed to summarize the data.

Results:

In this study, anencephaly (30.9%) and spinal bifida (17.6%) were the most commonly reported form of CAs. A single case of the imperforated anus, minigocephalocele, severe spinal bifida, twin transfusion syndrome, polyhydramnios and the umbilical hernia was also diagnosed during the study period. Nearly half percent (48.5%) of women who gave birth with CAs consumed less than one meal of meat per week, and 33% of women consumed 1-3 meals of fresh vegetables per week during their pregnancy. Furthermore, the reported consumption of folic acid and intake of iron during the current pregnancy was 23.3% (95% CI: 17.2, 33.7) and 47.8% (95% CI: 32.6, 61.9), respectively.

Conclusion:

The incidence of CAs in the study area is high. Consumption of a range of vegetables and fruits may reduce the development of Cas; hence, educational interventions that improve women's healthy diet practices must be considered. We also recommend further studies to better understand the relationships between the dietary status of women and the incidence of CAs.
The Probabilistic Porous-Solid Model
Authors: Rojas Eduardo
Published: October 2022

: In the previous chapter, a computational network porous-solid model was
developed to simulate the hydraulic behavior of unsaturated soils. However, important
computational constraints make this model unpractical. In this chapter, a probabilistic
porous-solid model is developed to overcome these constraints. The probabilistic
model is an alternative to the use of computational network models and shows
important advantages. This model is built from the probability of a certain pore to be
filled or remain filled with water during a wetting or drying process, respectively. The
numerical results of the probabilistic model are compared with those of the
computational network model showing only slight differences. Then the model is
validated by making some numerical and experimental comparisons. Finally, a
parametric analysis is presented.
Undrained Tests
Authors: Rojas Eduardo
Published: October 2022

When undrained triaxial tests are performed, two main phenomena occur.
First, the compression of the sample produces an increase in the degree of saturation
and therefore, a reduction in the value of suction. Second, with the reduction in the
sizes of pores, the retention curves shift on the axis of suction. Thereafter, the
simulation of undrained triaxial tests requires the correct simulation of the
hydromechanical coupling phenomenon. A fully coupled constitutive model for
unsaturated soils is used herein to simulate the behavior of unsaturated soils subjected
to undrained conditions. The mechanical model is based on the modified Critical State
model and the effective stress concept. The hydraulic model uses the grain and pore
size distributions to approximately reproduce the structure of soils. This model is able
to simulate the soil-water retention curves during wetting-drying cycles. Plastic
volumetric strains modify the pore size distribution of the soil, which in turn affects
the retention curves and, therefore, the current effective stress. Some comparisons
between numerical and experimental results of undrained triaxial tests show the
adequacy of the model.
O Crasto de Soure no Estuário do Mondego no Final do I Milénio a.C.: as evidências materiais

Published: October 2022

The Crasto de Soure pairs up among the archaeological sites linked to protohistory and Romanisation of the Mondego lower basin. However, despite the interventions made and the supposed relevance of the archaeological settlement, only the preliminary news of the first archaeological excavations carried out in 1987 and 1990 are known. These were the most extensive works carried out at the site and provided a significant set of artefacts that have remained partially unpublished. In this regard, rather than reporting new findings at the site, this paper aims to explore the data gathered in those campaigns. A special focus is given to the study of material remains, which constitute the fundamental element to link the site to what will be a turning point in the occupation of this territory - the end of the 1st millennium BC
Ofícios e Pequena Indústria em Penafiel Caldeireiros
Authors: Soeiro Teresa
Published: October 2022

Following the overview of the coppersmith craft in the country we now focus on Penafiel where, since the 1840s, it gained unprecedented visibility due to the setting up of a professional coppersmith, Manuel Cunha, in the city. We trace the “Coppersmiths Cunha” family path investigating how they settled in, the strategies adopted to ensure economic viability, and the transmission of know-how from generation to generation. Later, with the Penafiel region needs met, the newer generations set out to conquer new markets. In this expansion process they established coppersmith shops all over Entre-Douro-e-Minho. These were in great demand when the family, at the turn of the 20th century, added to their traditional activity the preparing and installation of complex alembics, and the making and repairing of sprayers for agricultural use that became indispensable since the blight emergence
A Dual-PRF Scan Mode and Adaptive Doppler-Velocity Dealiasing to Increase Radar Clear-Air Velocity Data Coverage and Usability
Authors: Xu Qin , Nai Kang , Melnikov Valery
Published: October 2022

By using long pulses with extended dwelling time, lowered pulse repetition frequency (PRF) and reduced Nyquist velocity, the radar measurement capability can be enhanced to increase clear-air Doppler velocity data coverage (which is beneficial for radar wind analysis and data assimilation and motivated our previous study). This potential capability is further explored (beyond our previous study) by not only modifying the existing operational clear-air scan mode with a lowered PRF and reduced the Nyquist velocity (to nearly 12 m/s) but also coupling this low-PRF scan with a high-PRF scan into a new dual-PRF scan mode. With this dual-PRF scan mode, the velocities from the high-PRF scan can be used to dealias the raw velocities from the low-PRF scan. Doppler velocities collected by using the low-PRF scan in this dual-PRF scan mode exhibit enhanced clear-air data coverage but encounter increased difficulties in dealiasing beyond the radial range covered by the high-PRF scan. To overcome the encountered difficulties, the previously developed alias-robust variational method for analyzing severely aliased radar velocity observations with small Nyquist velocities is further improved adaptively, so reliable reference radial velocities can be obtained and used to dealias the low-PRF scanned raw velocities on range circles beyond those covered by the high-PRF scan.
Concordance and Accuracy of Teledermatology Using Mobile Phones in the Outpatient Clinic of Jose R Reyes Memorial Medical Center: Cross-sectional Study
Authors: Preclaro Ivan Arni Caballero , Gulmatico-Flores Zharlah , Tianco Elizabeth Amelia Velasco
Published: October 2022

Background

Dermatologists rely on visual findings; thus, teledermatology is uniquely compatible to providing dermatologic care. The use of mobile phones in a store-and-forward approach, where gathered data are sent to a distant health provider for later review, may be a potential bridge in seeking dermatologic care.

Objective

This study aimed to determine the agreement between face-to-face consultations and teledermatologic consultations through the store-and-forward approach using mobile phones and its accuracy compared to a histopathologic diagnosis.

Methods

The study design was a cross-sectional study of participants consecutively recruited from dermatology patients who presented with skin or mucosal complaint and without prior dermatologist consultation. Photographs were taken using a standard smartphone (iPhone 6s Plus), and a 4-mm skin punch biopsy was taken on each patient—the gold standard to which the study result was compared to. The photographs were sent to 3 consultant dermatologists using a store-and-forward approach, for independent diagnosis and treatment plan.

Results

A total of 60 patients were included, with a median age of 41 years. There was moderate-to–almost perfect agreement in terms of final diagnosis between the face-to-face dermatologic diagnosis and teledermatologic diagnoses. The third teledermatologist had the highest agreement with the clinical dermatologist in terms of final diagnosis (κ=0.84; P<.001). Among the 3 dermatologists, there was moderate-to–almost perfect agreement as well. Agreement between pairs of teledermatologists ranged from 0.45 to 0.84. The 3 teledermatologists had moderate-to-substantial agreement with the biopsy results, with the third teledermatologist having the highest accuracy (κ=0.77; P<.001). Overall, there was a moderate agreement in the diagnosis of patients across raters.

Conclusions

Teledermatology is a viable alternative to face-to-face consultations. Our results show moderate-to-substantial agreement in diagnoses from a face-to-face consultation and store-and-forward teledermatology.
El acto suicida en el cristianismo
Authors: Montes Vargas Pablo
Published: October 2022

Christian theology has manifested different standpoints along its history; however, despite tolerating suicide in the beginning, it has always been a problem both theoretical and practical. So, the question addressed is: Are love for God and love for oneself practical and theoretical concepts sufficient for negating the suicidal act? Since this is an in-depth question and a complex issue, this paper outlines the topic from a historical and systematic perspective to identify the main landmarks of the history of Christianism and the different arguments developed for negating or tolerating the suicidal act. This leads us to outline a future research line from ontology and technologies associated with suicide.

Published: October 2022

A multi-item producer-retailer integrated system featuring overtime and random scrap is studied. The objectives are to jointly decide the most economic rotation fabrication cycle time and distribution of products. In order to meet the increasing demands of diversified end items, production managers today need to plan a multiproduct fabrication schedule and to expedite both manufacturing and transportation times so that they can meet product demands as quickly as possible. Also, due to potential uncontrollable reasons, scrap items are generated randomly in a real fabrication process. To address the aforementioned issues, this study examines a multi-item producer-retailer integrated system featuring overtime and random scrap. We build a mathematical model to interpret the proposed multi-item producer-retailer integrated system which incorporates shipping and retailer’s holding cost. The Hessian matrix equations are used for solving the optimality of the system. Diverse important system information can now be exposed to backing managerial decision makings, which includes individual and combined influences of variations in particular system factor(s) (such as scrap rate and overtime related parameters) on the specific system performance.

A novel freezing unit was developed for use in ceramic processing by the freeze casting technique. This step is crucial, since the macrostructure promoted by this technique is formed during freezing. Several authors present basic information about the apparatus used in the freezing step, but there are no studies that describe a complete unit as we do in this work and there is no commercial equipment for this purpose. The components of the freezing unit were selected according to function, suitability to project, cost and market availability. Advanced ceramic samples of ZnFe2O4, MnFe2O4, CoFe2O4, NiFe2O4, SiO2, Al2O3 and metallic Cu were produced using the freezing unit and the results of typical macrostructure and porosity analysis validated the chosen setup.
Mask and Respirators: Disease Control and Prevention

Published: October 2022

Abstract: The current pandemic has pushed everyone to seek solutions for a reusable, stable and 100% effective face mask. This is due to common filter masks tend to gradually lose the ability to filter viruses and bacteria. All available masks for Covid-19 are mostly efficient 95%. These masks protect face from droplets released by another person in atmosphere which may contain Corona virus molecules. But these masks have efficiency of only up to 95% and these masks actively do nothing to stop Covid-19 from spreading. Thus, this type of masks is called Passive Masks On the contrary, Active Mask is absolutely stable because it does not only filter but inactivates the virus and/or bacteria, according to the systems used to tackle the viruses and bacteria. Active Masks are not only minimally 99.99% effective but also user has access to free airflow and thereby these types of masks are also comfortable for elderly or people with respiratory illness

As a result, The number of days of heat wave was found to be of the highest score in the climate exposure category. Second , Green area density was found to be of the highest score in urban sensitivity category. Third, Gross Regional Domestic Product (GRDP) and health and medical facilities in the region were found to be of the highest score in adaptability category. Fourth, Grid was found to be particularly excellent. Based on the results of the previous analysis the complementary points are as follows. In order to reduce the damage caused by the current heat wave, facilities such as sprinklers and fagora should be expanded to develop adaptability. Also, efforts should be made to prevent heat stroke and dehydration by expanding the number of firefighters and rescue workers. In Addition, additional indicators should be reflected to confirm the current status of each local government. Meanwhile, Based on this study, it is significance in that it can be used as a basic data to enhance the analysis of heat wave disaster vulnerability.
Quantifying fermionic interactions from the violation of Wick's theorem
Authors: Pachos Jiannis K. , Vlachou Chrysoula
Published: October 2022

In contrast to interacting systems, the ground state of free systems has a highly ordered pattern of quantum correlations, as witnessed by Wick's decomposition. Here, we quantify the effect of interactions by measuring the violation they cause on Wick's decomposition. In particular, we express this violation in terms of the low entanglement spectrum of fermionic systems. Moreover, we establish a relation between the Wick's theorem violation and the interaction distance, the smallest distance between the reduced density matrix of the system and that of the optimal free model closest to the interacting one. Our work provides the means to quantify the effect of interactions in physical systems though measurable quantum correlations.

Published: October 2022

Periodontal risk assessment is essential to ensure the successful outcome of periodontal therapy. Various assessment tools have been devised over the years of which the periodontal risk assessment(PRA) tool by Lang & Tonetti is one of the more authentic tools, and it assesses the risk of severity of periodontal disease by taking into account various components which are a combination of risk factors, indicators, and markers. The present study used this tool to evaluate the change in periodontal risk following phase 1 periodontal therapy. Following the approval from the institutional ethical committee, 299 male and female patients aged 18 to 60 years undergoing comprehensive clinical care (CCC) at ISNC dental clinics from October 2020 until April 2021 were selected, and PRA was assessed at baseline (before phase 1 therapy) and following a re-evaluation of phase 1 therapy (4-6 weeks after phase 1 therapy). All the parameters of the Lang and Tonetti’s PRA model were recorded, and the periodontal risk was calculated accordingly. The data collected was entered into a Microsoft excel sheet. Statistical analysis was carried out using SPSSV 22 software. The results showed significant differences in essential risk parameters – sites with bleeding on probing(BOP), alveolar bone loss, and polygon surface area for risk. (P<0.05). These were the expected parameters to change following phase -1 therapy, thus having a profound influence on the periodontal risk. However, chi-square values showed no changes in systemic and general factors and smoking. (P>0.05) These factors are usually permanent and often impossible to eliminate, even if under control. Concerning smoking, even if the patients quit or reduce the number of cigarettes smoked, the alteration in risk levels is minimal or negligible. Thus, Phase 1 periodontal therapy significantly influences the risk levels in adult patients.
Influence of Various Forms of Education on the State of Human Capital as a Factor of Production in the Regions of Russia
Authors: Zhiryaeva E. V. , Dmitriev P. A.
Published: October 2022

The study aims to identify the role of university and professional education in the formation of human capital, which is embodied in different rates of economic development at the regional level in the Russian Federation. With the method of regression analysis we compare the level of education of the population with the rating of universities located in the constituent entity of the Russian Federation. Using the methods of endogenous growth theories, the contribution of human capital to the interregional difference in gross regional product per capita was estimated. The absence of a relationship was found between the dependent variable (gross regional product per capita) and the independent variables (education index, the number of universities in the list of the best universities). When comparing two regions of the Russian Federation, in which the discrepancy between the rating of universities and the level of education was most obvious, it was found that the difference in gross regional product per capita is completely determined by the state of human capital. This distinguishes subnational comparisons from cross-country comparisons, where physical capital and related to technologies residuals play a role. Among the considered indicators of higher, professional education, postgraduate and doctoral studies, the relative level of professional education seems to be most significantly affect at the growth of the region’s well-being, expressed in gross regional product per capita.

Authors: Bakhlova O. V. , Bakhlov I. V.
Published: October 2022

Aims: identification of the advantages and vulnerabilities of the Union State of Belarus and Russia as an integration format.

Methods: informal substantive analysis of documents, formal legal method, SWOT analysis.

Results and discussion: The strengths and weaknesses of the Union State of Belarus and Russia, opportunities and threats in internal and external dimensions are shown. The corresponding matrices characterizing the parameters of their probability and values for the Union construction are constructed. The content of integration decisions and agreements in key areas of Russian- Belarusian integration is analyzed. The peculiarities of the positions of the member states of the Union State on topical issues of the integration agenda are emphasized.

Conclusion: The saturation of the analyzed evaluation areas demonstrates a high degree of probability of the realization of both relevant opportunities and threats to the Union State of Belarus and Russia in internal and external dimensions. With a less risky development of events, it is internal factors that can change the qualitative characteristics of the process and the state of Russian-Belarusian integration — in a positive or negative sense. However, now a powerful destructive external influence is exerted on the Union State and its member countries, which can become the main driver of accelerating the “restart” of Russian- Belarusian integration.
ESG-transformation Policies and Procedures for Russian Companies
Authors: Tsygalov Yu. M. , Strizhov S. A.
Published: October 2022

ESG-transformation of Russian companies is inevitable. The introduction of a “carbon” tax in many countries, fines for exceeding the level of greenhouse gas emissions provided for in Russian legislation, the introduction of adaptive and transformational sustainable development projects and their verification systems do not leave domestic companies any other way of development. For ESG transformation, companies need to develop and implement a package of policies and procedures. The study of the experience of leading Russian companies allowed us to define a framework list of policies and procedures necessary for ESG transformation and recommend the priority of their implementation. The purpose of the study is to identify and systematize the policies and procedures necessary for the ESG transformation of the corporation. The objectives of the study are the analysis of documents of Russian companies reflecting the implementation of the ESG agenda; the definition of framework policies and procedures and recommendations on the priority of their implementation. The study used methods of generalization, analysis and synthesis in terms of the study of methodological and legislative approaches to the formation of the ESG strategy of the corporation. It is necessary to start the transformation with the development of the G — corporate governance policy. Within the framework of this policy, the initial ones are image and control procedures, inventory of greenhouse gases, analysis of the industry value chain.
EX VIVO TERAHERTZ IMAGING REFLECTION OF MALIGNANT AND BENIGN HUMAN BREAST TUMORS
Authors: Al-Ibadi Amel
Published: October 2022

This study evaluated the effectiveness of spectroscopy and imaging tools, using a previously-unexplored (0.2- 1.4) terahertz range, for investigating tumors in human tissue and distinguishing between malignant and benign cancer cells. One advantage of this technique is that terahertz radiation in this frequency range passes through human tissue without causing ionization or any negative effects To assess the effectiveness of this band of frequencies, THz data were collected from 10 different fresh breast tissue samples, extracted directly after excision. The optical properties were investigated at a range of low frequencies and THz imaging revealed good contrast between the different types of fresh tissue. Observations indicated that the optical and electrical properties in the low-frequency (0.3-0.5) range provided accurate information about breast cancer tissue. These results demonstrated the effectiveness of the technique up to 0.5 THz for ex vivo studies in medical applications.

Published: October 2022

Static random-access memory is a significant portion of digital system.
The major problem of SRAM cell is the leakage of power. A shorted-gate
fin-type field-effect transistor based SRAM cell design using leakage
control transistor technique is proposed in this manuscript for
minimizing the leakage power delay and power delay product. The proposed
SG FinFETs based SRAM cell design using LECTOR technique is mainly used
for stacking improvement to minimize the leakage power dissipation.
LECTOR technique is mainly dependent on stacking of transistors, in
which, two additional transistors are applied to lessen the leakage
current and delay. The leakage control transistor utilizes two
additional transistors are placed in series amid the pull up and pull
down network that means additional SG FinFETs PMOS transistor inserts
amid the pull up network and output terminal. The simulation of the
proposed SGFinFETs based Static Random-Access Memory using LECTOR
technique is in HSPICE simulation tool. Therefore, the proposed
SGFinFETs based SRAM design using LECTOR method attains 11.31%, 51.47%
and 45.46%, lower read delay, 44.44%, 26.33% and 33.45% lower write
delay, 36.12%, 45.28% and 26.45% lower read power, 34.5%, 33.56%,
22.41% lower write power, 37.4%, 15.3% and 26.54% higher read SNM
and 33.67%, 35.8%,12.09% higher write SNM compared to three existing
methods.
Improved Performance of TS-FLC Based BESS for Power Quality Improvement of Grid Connected Hybrid Renewable Energy System

Published: October 2022

When coupled with the appropriate controller, a battery energy storage
system (BESS) is the most effective energy storage technology for
diminishing system fluctuations due to atmospheric and meteorological
variabilities. This work proposes DC and AC side controllers, for a
hybrid wind-PV-BESS connected to the grid, based on Takagi Sugeno-Fuzzy
Logic Controller (TS-FLC). When unbalanced loads are connected to the
Point of Common Coupling (PCC), the suggested inverter controller helps
balance grid currents, reduce harmonics caused by non-linear loads, and
compensate for reactive power demand by the load. The same inverter may
provide active power to the grid and act as a maximum power point
tracker (MPPT) as the battery’s State of Charge (SoC) reaches its
maximum, so a separate converter is not necessary to get the
maximum power. TS-FLC controller in various case scenarios have been
tested using MATLAB and is compared to the Proportional Integral (PI)
controller. Though both controllers work effectively but TS-FLC has an
extra edge over PI controller and Mamdani Fuzzy controllers as per
IEEE-519 standard. TS-FLC is capable of reducing source current
harmonics up to 0.08% (steady - state) and 0.10% (with fault), while
source current harmonics reduction with PI controller is comparatively
much higher.
Influence of Parameter Changes on The Operation Characteristics of Circuit Breaker with Oil Dashpot at Low Temperature
Authors: SU Xiuping , JIA Yanqing , SHI Hongwei , FU Zhe
Published: October 2022

The iron core in the circuit breaker of oil dashpot is mainly affected
by the electromagnetic force, spring force and oil damping force, which
can play the function of anti-time protection when overload current is
excited. At low temperature, the viscosity of the methyl silicone oil
damping fluid will change, and the parameters of spring and iron core
will also change with temperature. The change of this parameters will
lead to the change of the resultant force on the iron core, which will
affect the operation time. To analyze this problem, a correlation model
is established. Through the measurement of parameters at low
temperature, numerical calculation, electromagnetic analysis, simulation
analysis and compared with the experimental results. The study found
that the viscosity of the damping fluid increases, the iron core is
deformed, and the spring stiffness increases at low temperature. The
influence of a single factor on the operation characteristics of the
tripper is not enough to reflect its overall characteristics, and the
comprehensive effect of each factor needs to be considered. After
comprehensively considering all factors, the results are closer to the
experimental results. The results provide a theoretical basis for the
optimization design of the circuit breaker.

Lithium-ion battery cells are used for energy storage in many industrial sectors, such as consumer electronics or electromobility. Due to the diversity of these applications, the demand for tailored battery cells is increasing. Consequently, the technical development of the cells leads to numerous coexisting cell variants. Examples of such variants are altering cell materials, formats, and capacities. Different target capacities can be realized by changing the geometrical dimensions of the individual electrodes or the number of electrodes in the cell cores. The increasing quantity of variants poses challenges within battery cell manufacturing, such as the need to adapt the process parameters for the cell-internal contacting of a higher number of electrode sheets in the cell stack. Each new cell variant currently requires elaborate experimental parameter studies for its manufacture. An approach for selecting suitable process parameters for laser-based cell-internal contacting in terms of a modification of the cell properties is presented in this paper. A model was built to determine the weld depth in copper sheets using a millisecond pulsed laser welding strategy. The process parameters for welding stacks of electrode sheets to an arrester tab were calculated on the basis of this model. The necessary weld depth in the arrester tab for achieving suitable mechanical properties of the cell-internal joint was considered. The presented approach was validated by welding different numbers of foils to an arrester tab and varying the thickness of the foils. It was shown that the experimental effort for the selection of the process parameters for laser-based contacting can be reduced significantly.

This study aims to determine the effect of soaking time in distilled and non-distilled liquid smoke of kusambi wood (Schleicera oleosa) on the quality of smoked skipjack fillets. This study used an experimental method designed with a completely randomized design (CRD) with two factor treatments. The first factor was soaking time with four levels, namely 10, 20, 30 and 40 min. The second treatment factor was the type of liquid smoke from kusambi wood (without and with distillation). The variables observed in this study focused on the quality of the smoked skipjack fillets after the 8-day storage period, including: water content (%), pH, total acid (%), fat content (%) protein (%) and phenol content (%). The results showed that the liquid smoke of kusambi wood with distillation had a pH of 3.18 which was more acidic and had higher phenol content (0.61%) and acid content (17.62%) than liquid smoke without distillation. Of the eight treatment combinations, the quality of smoked skipjack fillets after 8 days of storage, it is found that the treatment of soaking 30 min and 40 min in distilled liquid smoke is the best treatment and meets the quality requirements of SNI. This is based on the value of water content (48.46% and 49.67%), pH (4.04 and 3.96), total acid (8.84% and 9.07%), fat content (4.85% and 4.92%), protein content (18.04% and 17.83%) and phenol content in smoked skipjack fillets (0.65% and 0.61%). Keywords: liquid smoke, distillation, soaking time, quality of smoked skipjack fillet
Design and Implementation of a Three-Phase Converter in a Solar PV System
Authors: Kumar Satyendra , Tiwari Prakash Narayan
Published: October 2022

A model of a solar panel array with variable irradiance and temperature is included in the study described here. Because each array receives a different amount of irradiation, the output varies. The system's output power has shifted as a result of this fluctuation. The work done here is done to adapt temperature and irradiance fluctuations in the solar panels and to increase the power output produced by the renewable energy source. With the suggested modulation technique, which has a simplified computational methodology, the levels of a multilevel inverter can be any number. This approach would be preferable for a solar system with variable input variables that generates consistent and effective output power.
