Published: October 2022

It is very important to predict the acoustic radiation of vehicle body for the control of interior noise. Firstly, the kinetic equations of coupled acoustic-structural finite element method are explained and the numerical analytical methods of noise transfer function and acoustic panel participation are further obtained. Then the coupled acoustic-structural finite element model of body in white and passenger compartment cavity of a minicar is established and verified by modal test. The passive side of engine mounting points are chosen as the excitation points, and driver’s right ear is the output point of sound pressure response. The noise transfer function is calculated and the critical frequency of vehicle interior noise is obtained. The acoustic panel participation analysis of vehicle roof and floor are conducted, and the key acoustic panels are identified. In order to reduce the noise of critical frequency, the measures, pasting damping material and welding beam, are adopted. The results indicate that, compared with the results of structure improvement of modal method, the vehicle interior noise is controlled more effectively by using the acoustic panel participation analytical method.
A fault diagnosis approach of reciprocating compressor gas valve based on local mean decomposition and autoregressive-generalized autoregressive conditional heteroscedasticity model
Authors: Lei Na , Tang Youfu , Lei Yong
Published: October 2022

Vibration signal of reciprocating compressor gas valve represents nonlinear, non-stationary and multiple impulse characteristics. To extract the features of the signal, an integration approach based on local mean decomposition (LMD) method and autoregressive-generalized autoregressive conditional heteroscedasticity (AR-GARCH) model is proposed. First, the property of LMD is investigated in the paper, which indicates that LMD method not only can effectively alleviate non-stationary feature and restrain the end effect of non-stationary signal, but also can accurately improve the resolution of time-frequency analysis. Then, the first five PF components of gas valve signal are modeled by AR(1)-GARCH(1, 1) model as the feature vectors without any prior knowledge about the fault mechanism. Finally, the BP neural networks are applied to diagnose the faults of reciprocating compressor gas valve based on the feature vectors above. The results indicate that high diagnosis accuracy can be obtained by integrating LMD method and AR-GARCH model. So the approach proposed in the paper provides an effective measure to extract the fault feature of reciprocating compressor gas valve.
Mitigation of wind-induced vibration of a tall residential building using liquid column vibration absorber
Authors: Cho Bong-Ho , Yu Eunjong , Kim Hongjin
Published: October 2022

The most important thing in applying mass type dampers including Liquid Column Vibration Absorber (LCVA) is tuning its natural frequency to an optimum value which is a function of the natural frequency of the building and the mass ratio of damper to the building. However, exact prediction of the natural frequency of the building at design stage is very difficult especially for concrete buildings. Thus, continuous updating of the target frequency and correction of the design of the damper based on field measurement is necessary. In this paper, application of LCVAs to mitigate the wind-induced vibration of 64-story residential buildings is presented. The LCVA were designed to have adjustable dimension for vertical column to take the advantage of ease tuning and wide frequency range. For updating of initial design, the tuning and performance assessment of LCVA several tests and measurement were carried out. The ambient vibration measurement of a partially completed building and a completed building without water in LCVA was performed and final values of the width of vertical column and the height of water were determined from the system identification results based on the collected acceleration data. In addition, ambient vibration measurement of buildings with LCVA water was performed and the system identification results indicated that the apparent damping ratio due to LCVA was increased about 3.13 to 3.89 times.

Authors: Feng Xue-li , Hu Jie
Published: October 2022

The parallel mechanism was adopted as seat suspension system in this paper. And the active joints with damping springs as the reduction vibration actuator, the reduction vibration seat model with 3-PRPS parallel mechanism which had six degree of freedom was established. With position of the mechanism as the premise, stability indexes of the reduction vibration seat in motion were proposed. As a result, the task space of the moving platform was obtained according to the inverse solution of the mechanism position. To reduce vibration effectively, velocity matrix of branched chain was built by means of vector method. The structural parameters were obtained by the numerical computation to improve the reduction vibration space and flexibility. Based on the above analysis, the simulation model can be obtained. In order to verify the reliability of the simulation model, the experiment of vibration acceleration transmissibility was conducted and the result was then compared with that of the numerical computation. Their results were consistent with each other. It indicated that the simulation model was reliable and could be used for the subsequent analysis. Then, influence factors of vibration acceleration transmissibility were researched based on the verified simulation model. In order to obtain a suspension system with better reduction vibration performance, making the maximum vibration acceleration transmissibility in the vertical and horizontal be minimal was set as the optimization objective. And the above influence factors were taken as the design variables. Finally, the ride comfort of vehicles was improved. Meanwhile, this research can also provide some references for the similar engineering problems.
Effects of motion-induced aerodynamic force on the performance of active buffeting control
Authors: Sun Jie , Li Min
Published: October 2022

During buffeting control of an aircraft, there consequently is a motion-induced aerodynamic force. However, it is not yet clear whether this additional force must be considered in design of control law. In this paper, to hopefully answer this interesting question, effects of the motion-induced aerodynamic force on the active buffeting control during control law design are studied. The macro fiber composite (MFC) actuator is modeled by employing the load simulation method, and the motion-induced unsteady aerodynamic forces are computed by the doublet-lattice method. Two different controllers, i.e. one with the motion-induced aerodynamic force and another without it, are simultaneously designed based on the linear quadratic Gaussian (LQG) control method. And, two corresponding models are respectively developed. Then, the control effects of the two models are compared and the physical mechanisms are discussed. From our simulation results it is found that the motion-induced aerodynamic forces do influence the buffeting responses depending on airflow velocity. The differences of the control effects of the two models are smaller at lower airflow velocity below the flutter velocity, however with the increase of the airflow velocity the control effect of the model considering the motion-induced aerodynamic force is much better. The larger the velocity is, the more significant the differences are. Finally, the energy dissipation of the motion-induced aerodynamic force is examined and found to be a main factor influencing the differences of the two models.

Authors: Chen Xiaozhe , Kong Xiangxi , Dou Jingxin , Liu Yunshan , Wen Bangchun
Published: October 2022

In this paper, we study the coupling dynamic characteristic of a single mass vibration machine driven by two eccentric rotors rotating oppositely. According to the coordinate of rotor flux, we deduce the electromagnetic torque of an induction motor in the steady state operation. From three ways of numerical analysis, model simulation and experiment, we discuss the coupling dynamic characteristic by using the actual parameters of this vibration machine. The results show that when the synchronization condition is satisfied, not only the vibration synchronization transmission can be achieved, but also the synchronization motion of the two motors with different power supply frequencies also can be achieved. The phase of the bigger mass-radius product lags behind that of the smaller one, the phase of the bigger distance between the rotation center of eccentric rotor and the mass center of the vibration rigid body lags behind that of the smaller one, and the phase difference decreases with increasing the synchronization velocity. We present a new method that adjusting the power supply frequencies of the two motors to make the vibration system with different structure parameters carry out the 0 phase difference, and its feasibility is verified by experiment.
Grid-connected isolated shoot-through Z-source inverter with coupled inductor based on novel control strategy
Authors: Su Hongsheng , Lin Hongjian
Published: October 2022

This paper presents a new grid-connected control strategy based on a new type of Z-source inverter. For this Z-source inverter, a coupled inductor is used to displace the inductor connected to the positive of the power supply in traditional Z-source topology and its position relative to the three-phase inverter bridge has changed. In contrast with traditional Z-source inverter, it can achieve higher voltage gain, lower capacitor voltage stress during steady state and suppress inrush current at startup. Last, it is modeled in two-phase static frame and then a grid-connected power loop and a capacitor voltage loop are used to realize it to connect grid. Simulation results show that by this new grid-connected strategy, this Z-source inverter can reach its grid connection with high power factor and the system can work in good stability, strong robustness and dynamic performance.

A novel type of hybrid ultrasonic motor using longitudinal and torsional vibration modes is presented, which has four side panels uniformly distributed along the circumference of the stator cylinder. There is rectangle piezoelectric ceramics (PZTs) based ond31effect bonded on both sides of each side panels, which can be used to convert the first bending vibration mode of the side panels into the second torsional vibration mode of the stator when the exciting voltage is applied. Meanwhile, there are rectangle PZTs based ond31effect bonded on the surfaces of the stator cylinder between every two side panels, which can be used to excite the first longitudinal vibration mode of the stator. The simulation results using finite element method (FEM) software Workbench reveals the suitable polarization arrangement of PZTs and the final designed structure of the motor. The appearance size of the prototype is 28.2 mm×28.2 mm×68 mm, while the outer diameter of the stator cylinder is 20 mm. The major vibration and mechanical characteristics of the prototype have been measured. The working frequency of the prototype measured in experiment is around 43.12 kHz, which is consistent with the numerical results. When operating voltage of 350 Vp-pis applied, the no-load speed of the prototype is 103 rpm and the stalling torque is 48 mN·m.

Analysis of axial stiffness characteristics of a mechanism of fluid bag shock absorber under alternative factors
Authors: Zhang Ming , Jiang Rongmin , Nie Hong
Published: October 2022

A mechanism of fluid bag shock absorber which could provide axial shock protection under small displacement and small deformation was designed. The finite element model of the mechanism was established in ABAQUS, the different types of loads imposed on the bottom of mechanism when the mechanism worked in different environment were described and the load stiffness matrix was obtained when pressure loads were imposed on the mechanism. The effects of the notch in fluid bag on axial stiffness characteristics were discussed. The results indicate that the flip of inner shell occurs as the axial concentrated load is imposed to the bottom of inner shell and the notch in fluid bag has little effects on the increment of pressure and volume variation of bag. The equivalent axial force generated by pressure loads imposed on the inner shell was calculated, the axial displacement of inner shell as well as increment of bag pressure caused by pressure loads is larger than concentrated load. The effects of different factors affecting the axial stiffness characteristics were discussed. The factor of load type has almost no effects on the axial stiffness variation, and has small impact on the increment of pressure variation of bag; Outer shell appears to be one of the crucial factors affecting the axial stiffness and increment of bag pressure variations; Fluid bag is the key factor determining the axial stiffness characteristics of mechanism, both of the axial displacement of inner shell and increment of bag pressure increase with loads when the pressure loads are imposed on the surface of fluid bag.

Authors: Acciani Giuseppe , Adamo Francesco , Di Modugno Filomena , Gelao Giancarlo
Published: October 2022

Energy Harvesting (EH) is the science that studies the conversion of energy dispersed in environment into a different and more useful form of energy, mainly the electrical one. In recent years, several energy-harvesting devices using piezoelectric materials have been developed to transform environmental vibrations into electrical energy. Since most piezoelectric energy harvesters are in form of cantilevered beams, the aim of this paper is to model and simulate a cantilever beam as energy harvester from wind-induced vibrations. The behavior of a cantilever beam with a fixed configuration (dimensions, materials, boundaries and shape) subjected to wind pressure was observed in an experimental apparatus and the reaction of the same device was described with a mathematical model based on piezoelectric constitutive equations and mechanical equilibrium equations. The device was simulated with the Comsol Multiphysics software that implements the equations of the mathematical model by the Finite Element Method (FEM). The experimental results were used to validate the simulation environment and their comparison with calculated results allows an appropriate choice of the most suitable piezoelectric material, among natural crystals, piezo ceramics, piezo polymers and piezocomposites, for this type of cantilever.

Authors: Xu Juncai , Ren Qingwen , Shen Zhenzhong
Published: October 2022

Low strain detection, an indirect and nondestructive testing method, is one of the main pile integrity testing methods. We propose low strain testing analysis based on a synchrosqueezing wavelet transformation (SST). Through a typical model pile test, the SST is applied to identify pile bottom signal reflection time and to separate signal from noise. It is also compared with the conventional wavelet de-noising and the empirical mode decomposition (EMD) de-noising method. Results show that the SST technique can be used to identify the reflected signal of the pile bottom, achieve signal and noise separation, and improve signal-to-noise ratio. The method has significant advantage in low strain detection signal processing compared to other methods.
Analysis of vibroacoustic estimators for a heavy-duty diesel engine used in sea transport in the aspect of diagnostics of its environmental impact
Authors: Merkisz-Guranowska Agnieszka , Waligórski Marek
Published: October 2022

The paper describes the impact of a marine engine operation on selected vibroacoustic quantity estimators and their characteristics made in different signal domains. The authors focused on the assessment of the combustion process diagnostic for the engine operating characteristics to obtain information on its functional relations and its nature determined by changes in the main structural and operational point measures, in a powertrain of a non-road means of sea transport. In the empirical research, the vibration, acoustic signal generation and its propagation have been selected to obtain quantitative measures of an engine diagnostic assessment. The authors have confirmed that the considered vibroacoustic estimators and their specified characteristics can be useful for a continuous engine assessment in a vehicle during its normal operation, which gives additional tools to perform more accurate diagnostics under real stationary and non-stationary operating conditions. Furthermore, it makes it possible to identify malfunctions in regular operation of the means of transport, which can be also helpful in the identification of their sources. All such factors and the obtained analyses are in strict correlation with the present and future requirements of the international and domestic regulations for means of transport fitted with combustion engines.

Published: October 2022

Globalization has changed the corporate sector, allowing the wealthy to control the market. The weak side is excluded from competition and becomes a passive observer. This research examines the cash flow operations of Koyafa's savings and loan and trade sectors to establish its financial performance. The study incorporates quantitative data from Koyafa's financial records and qualitative data from the cooperative's AD/ART. Linear regression was employed using SPSS 25. According to the research, Koyafa has not prepared financial accounts in accordance with PSAK No. 27. The current financial records do not adequately represent Koyafa's competence to manage its finances. According to financial records, Koyafa's liquidity in meeting its short- and long-term financial commitments is still insufficient, even though company earns net money every year. Koyafa's net profit is adequate due of effective asset investment. Cash flow and liquidity have a favorable influence on cooperative earnings, thus it's important to manage them for better financial performance. Koyafa must restructure its company and inventories to meet its goal and objective.

Published: October 2022

The accounting profession faces significant challenges and noticeable changes due to the COVID-19 pandemic. The rising demand for digital talent and the need to ensure critical thinking skills are applied in making decisions have become the main challenges for accountants nowadays. A drastic change from the official site to working from home due to lockdown is an issue to be discussed. Therefore, based on case studies, this paper aims to discuss the effects of COVID-19 on the accounting profession. The selection of the case studies is based on the company awarded as Best Employer and Most Attractive Graduate Employers to Work in Malaysia in recent years. By focusing on the importance of digital and critical thinking, a framework is developed to show the transformation of the accounting profession over the last 50 years and future insights for the accounting talent in the current context. The findings show that the Accountant's traditional role of preparing a complete set of accounts is still vital and relevant. However, accountants need to equip themselves with digital and critical thinking skills to become future-fit accountants in the near future, especially in the post-COVID-19 era.

Myokine Response to Resistance Exercise in Older Adults and the Similarities and Differences to Younger Adults: A Brief Narrative Review
Authors: Cordingley Dean , Cornish Stephen
Published: October 2022

Myokines are cytokines secreted from muscle during contraction and are implicated in autocrine, paracrine, and endocrine regulation of biological systems. It is postulated that myokines contribute to skeletal muscle adaptations in response to resistance exercise. Exercise, including resistance exercise, is an important factor in the management of maintaining skeletal muscle strength, mass, and function with aging. Sarcopenia is exacerbated with increased age and therefore, it is important to understand the potential underlying mechanisms whereby exercise may be beneficial in reducing the consequences of sarcopenia for older adults. Myokine secretion is one mechanism which is postulated to account for the benefits of exercise in aging muscle. The response of myokines to aerobic exercise in older adults have previously been reviewed; however, there is limited research focused on the response of myokines to resistance exercise. Therefore, the aim of this narrative review is to discuss the response of various myokines to an acute bout of resistance exercise and/or chronic resistance exercise training in older adults, compare the response between younger and older adults, and briefly outline the influence myokines may have on skeletal muscle adaptations.

Authors: Fuster-Casanovas Aïna , Das Ronnie , Vidal-Alaball Josep , Lopez Segui Francesc , Ahmed Wasim
Published: October 2022

Background

Vaccination is one of the most successful public health interventions for the prevention of COVID-19. Toward the end of April 2021, UNICEF (United Nations International Children’s Emergency Fund), alongside other organizations, were promoting the hashtag #VaccinesWork.

Objective

The aim of this paper is to analyze the #VaccinesWork hashtag on Twitter in the context of the COVID-19 pandemic, analyzing the main messages shared and the organizations involved.

Methods

The data set used in this study consists of 11,085 tweets containing the #VaccinesWork hashtag from the 29th to the 30th of April 2021. The data set includes tweets that may not have the hashtag but were replies or mentions in those tweets. The data were retrieved using NodeXL, and the network graph was laid out using the Harel-Koren fast multiscale layout algorithm.

Results

The study found that organizations such as the World Health Organization, UNICEF, and Gavi were the key opinion leaders and had a big influence on the spread of information among users. Furthermore, the most shared URLs belonged to academic journals with a high impact factor. Provaccination users had other vaccination-promoting hashtags in common, not only in the COVID-19 scenario.

Conclusions

This study investigated the discussions surrounding the #VaccinesWork hashtag. Social media networks containing conspiracy theories tend to contain dubious accounts leading the discussions and are often linked to unverified information. This kind of analysis can be useful to detect the optimal moment for launching health campaigns on Twitter.
Efficacy of Internet-Based Acceptance and Commitment Therapy for Depressive Symptoms, Anxiety, Stress, Psychological Distress, and Quality of Life: Systematic Review and Meta-analysis
Authors: Han Areum , Kim Tae Hui
Published: October 2022

Background

Acceptance and commitment therapy (ACT) is an empirically supported transdiagnostic approach that involves mindfulness processes and behavior change processes for valued living.

Objective

This systematic review and meta-analysis of randomized controlled trials (RCTs) aimed to assess the efficacy of internet-based ACT (iACT) for depressive symptoms, anxiety, stress, psychological distress, and quality of life (QoL).

Methods

PubMed, CINAHL, PsycINFO, and SCOPUS databases were searched to identify relevant RCTs published up to June 5, 2021. The included RCTs were assessed using the Cochrane Collaboration risk-of-bias tool. The use of either a random effects model or fixed effects model was determined using I2 statistic values for heterogeneity. Subgroup analyses were conducted according to the type of control group, the use of therapist guidance, delivery modes, and the use of targeted participants, when applicable.

Results

A total of 39 RCTs met the inclusion criteria. Meta-analyses found small effects of iACT on depressive symptoms, anxiety, stress, psychological distress, and QoL at the immediate posttest and follow-up. There was no significant effect of iACT on stress at follow-up. Subgroup analyses showed small to medium effects of iACT on all the outcomes at the immediate posttest and follow-up compared with the passive control groups. In contrast, subgroup analyses that compared iACT with active control groups found no differences between groups on stress, psychological distress, and QoL at the immediate posttest or on depressive symptoms, anxiety, and stress at follow-up. In addition, subgroup analyses conducted according to the use of therapist guidance, delivery modes, and the use of targeted participants found no statistically significant subgroup differences among studies in all the outcomes, except for the subgroup difference among studies according to the use of targeted participants for depressive symptoms at the immediate posttest (ie, a statistically significant, larger effect of iACT when studies targeted people with depressive symptoms). The overall risk of bias across the studies was unclear.

Conclusions

The findings of this study contribute to the body of evidence regarding the effects of iACT on depressive symptoms, anxiety, stress, psychological distress, and QoL and may be applicable in any population, as ACT is a transdiagnostic approach. Few studies have compared iACT with active control conditions, especially for stress and psychological distress at the immediate posttest and follow-up. In addition, the active control conditions varied among the included studies. Further high-quality studies are needed to better understand whether iACT is comparable or superior to other evidence-based interventions, such as cognitive behavioral therapy, in decreasing depressive symptoms, anxiety, stress, and psychological distress and improving QoL.

Authors: Motahari-Nezhad Hossein , Al-Abdulkarim Hana , Fgaier Meriem , Abid Mohamed Mahdi , Péntek Márta , Gulácsi László , Zrubka Zsombor
Published: October 2022

Background

The introduction of new medical technologies such as sensors has accelerated the process of collecting patient data for relevant clinical decisions, which has led to the introduction of a new technology known as digital biomarkers.

Objective

This study aims to assess the methodological quality and quality of evidence from meta-analyses of digital biomarker–based interventions.

Methods

This study follows the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guideline for reporting systematic reviews, including original English publications of systematic reviews reporting meta-analyses of clinical outcomes (efficacy and safety endpoints) of digital biomarker–based interventions compared with alternative interventions without digital biomarkers. Imaging or other technologies that do not measure objective physiological or behavioral data were excluded from this study. A literature search of PubMed and the Cochrane Library was conducted, limited to 2019-2020. The quality of the methodology and evidence synthesis of the meta-analyses were assessed using AMSTAR-2 (A Measurement Tool to Assess Systematic Reviews 2) and GRADE (Grading of Recommendations, Assessment, Development, and Evaluations), respectively. This study was funded by the National Research, Development and Innovation Fund of Hungary.

Results

A total of 25 studies with 91 reported outcomes were included in the final analysis; 1 (4%), 1 (4%), and 23 (92%) studies had high, low, and critically low methodologic quality, respectively. As many as 6 clinical outcomes (7%) had high-quality evidence and 80 outcomes (88%) had moderate-quality evidence; 5 outcomes (5%) were rated with a low level of certainty, mainly due to risk of bias (85/91, 93%), inconsistency (27/91, 30%), and imprecision (27/91, 30%). There is high-quality evidence of improvements in mortality, transplant risk, cardiac arrhythmia detection, and stroke incidence with cardiac devices, albeit with low reporting quality. High-quality reviews of pedometers reported moderate-quality evidence, including effects on physical activity and BMI. No reports with high-quality evidence and high methodological quality were found.

Conclusions

Researchers in this field should consider the AMSTAR-2 criteria and GRADE to produce high-quality studies in the future. In addition, patients, clinicians, and policymakers are advised to consider the results of this study before making clinical decisions regarding digital biomarkers to be informed of the degree of certainty of the various interventions investigated in this study. The results of this study should be considered with its limitations, such as the narrow time frame.

Fiscal Decentralization and Natural Disaster Relief in China
Authors: Bo Wang
Published: October 2022

This paper analyzes the impact of fiscal decentralization on the level of government relief for natural disasters using 30 provincial-level data from 1997 to 2017 in China. The results show that fiscal decentralization positively impacts local government expenditure on natural disaster relief. Although it is different from the existing conclusion that fiscal decentralization inhibits the supply of local non-economic public goods, this conclusion can be explained by the literature on disaster prevention and control; the incentive of decentralization to increase government revenue increases the opportunity cost of disaster prevention and control investment, which makes the pre-disaster funds insufficient, and the post-disaster financial expenditure of natural disaster relief increase accordingly.

Authors: Pedersen Mette , Larsen Christian F. , Eeg Martin
Published: October 2022

Quantitative voice analysis for clinical use has been focused upon for many years. The aim was to test if Glottal Analysis Tools (GAT) could be used, based on High-Speed Video (HSV) to quantify distances between the vocal folds at any place on the vocal folds. The software includes a reproduced computed film of the vocal fold movements online. 20 normal HSV and 30 with insufficient closure in the rear part of the vocal folds (rear glottal gap) were compared in a case-control study. The distance of trajectories was chosen at 50% and 10% from the rear part of the glottis and maximum and minimum distances between the vocal folds were defined during phonation in the 2 groups. It was possible to calculate the absolute data of insufficiency of closure of the vocal folds compared to normal HSV with a statistical difference of p<0,0001. An interesting result was in this material also that functional closure was found in all images in the middle of the vocal folds. In the future quantification of voice disorders should include specific parts of the Glottal Area Waveform (GAW) analyses based on HSV for better differentiation of function and pathology of the vocal folds.

The Courses of Agrarian Sciences have been losing their original characteristics through the pasting years, especially after the WWII, under the influence of the ‘green revolution’ over agriculture practices worldwide, increasing productivity to address the hunger extinction. The productivity has been significantly increased since that. However, the hunger remains a huge concern across the world. This model also generated several social and environmental negative externalities. Some of reasons for these results are well-known. The agri-food systems were captured by few international corporations, who control the entire the food chains from the farms to the supermarkets shelves. Therefore, the courses of agrarian sciences are being realigned to prepare professionals to work only for these sectors of agriculture. Furthermore, these conglomerates are guided by the international commodity markets, undermining the local markets of food production and distribution. Notwithstanding, with the arise of agroecology movements, this model has been strongly questioned both inside the educational institutions and across the society. In this context, some universities launched courses with agroecological approaches, whose UNEMAT, in the Brazilian State of Mato Grosso, is one case, where the bachelor’s degree in agronomy incorporated not only the agroecological approach, but also an interdisciplinary teaching. That is the experience that this article is about. It includes an analysis of the historical, pedagogical and political aspects that influenced the course design, from its conception until its collapse. The lessons learned offer insights to how being more successful in designing new courses of agrarian sciences based on interdisciplinary and agroecological approaches.

Ferrites are ceramic like material having magnetic properties which are being utilized for several applications. Cobalt ferrites are hard magnetic material with high coercivity. In our study Crystalline, Magnetic nanoparticles of Cobalt ferrite Co0.8Fe2.2O4 were synthesized by Sol Gel Method using ferric chloride and cobalt nitrate with NaOH as a reactant. Structural characteristics of samples were determined by X-Ray diffraction, FESEM and TEM. Particle size found 14.26nm by using Debye Scherrer method. Scanning electron microscopic (SEM) studies revealed nano-crystalline nature of the sample. AFM showed surface roughness. Magnetic properties were investigated using VSM (vibrating sample magnetometer). Various magnetic parameters such as saturation magnetization (Ms) and remanence (Mr) and coercivity (Hc) are obtained from the hysteresis loops. The calculated value of saturation magnetization in our study for Cobalt ferrite was found lower than the value reported for the bulk. The coercivity was found very high which indicate that the nanoparticles exhibit ferromagnetic behavior.

Abstract: Privacy-preserving routing protocols in wireless networks frequently utilize additional artificial traffic to hide the source-destination identities of the communicating pair. Usually, the addition of artificial traffic is done heuristically with no guarantees that the transmission cost, latency, etc., are optimized in every network topology. We explicitly examine the privacyutility trade-off problem for wireless networks and develop a novel privacy-preserving routing algorithm called Optimal Privacy Enhancing Routing Algorithm (OPERA). OPERA uses a statistical decision-making framework to optimize the privacy of the routing protocol given a utility (or cost) constraint. We consider global adversaries with both Lossless and lossy observations that use the Bayesian maximum-a-posteriori (MAP) estimation strategy. We formulate the privacy-utility trade-off problem as a linear program which can be efficiently solved.

Abstract: Banks have been providing a better way for people to save and deposit money. With the advent of banks, payment and deposit methods became far more convenient than they were previously, but thefts continued to plague banks, causing millions of dollars in damage. These thefts have harmed the lives of thousands of businesses all over the world. Theft is increasing at a rapid pace as technology advances, but technological concepts such as artificial intelligence and machine learning have assisted businesses and individuals in dealing with these issues. Companies are using artificial intelligence to track down these thefts, from proper customer authentication to multiple level security checks. AI is proving to be a better way to combat these thefts. In this article, we discussed the most common types of theft and how to prevent them using artificial intelligence.

Published: October 2022

Introducción: el síndrome hemolítico urémico atípico es una enfermedad severa y huérfana, la cual en su variedad atípica se presenta con manifestaciones clínicas extrarrenales y sistémicas. La presencia de afectación gastrointestinal es infrecuente, pero en los pacientes en los que se manifiesta el pronóstico desfavorable, dado que estos cursan con más recaídas y mayor mortalidad, por lo cual se hace indispensable que el personal de salud esté entrenado en detectar y reconocer las manifestaciones menos frecuentes de esta patología, para así impactar positivamente en el desenlace de estos pacientes.
Objetivo: se busca ilustrar un caso singular en cuanto a la sintomatología presentada infrecuente por el paciente y sobre una etiología no descrita previamente en la literatura.
Presentación del caso: se reporta el caso de un escolar masculino de 8 años que presentó fiebre, ictericia, dolor abdominal y lumbar, diarrea, hematemesis y hematuria, al cual se le diagnosticó síndrome hemolítico urémico atípico. El paciente presentó un rápido deterioro clínico con compromiso multiorgánico, documentándose hipertensión arterial y lesión renal aguda, que recibió manejo con cristaloides y diurético de asa sin mejoría, por lo que requirió inicio de terapia de reemplazo renal e incluso múltiple soporte transfusional; sin embargo, continuó sin mejoría clínica, por lo que se indicó inicio de anticuerpo monoclonal IgG humanizado recombinante con buenos resultados.
Discusión y conclusión: este caso es un claro ejemplo de que la afectación extrarrenal y multiorgánica puede ser la manifestación principal de esta enfermedad, por lo que es importante que el clínico se encuentre sensibilizado y conozca los signos y los síntomas de la presentación atípica de esta patología, con el fin de evitar retrasos diagnósticos y terapéuticos. Asimismo, el abordaje etiológico es de suma importancia para brindar un pronóstico más preciso al paciente y su familia.

Published: October 2022

A color fusion image color harmony assessment framework based on joint
features is proposed. In this framework, the topic model is improved to
extract global natural statistical features, then the memory color
theory is proposed to calculate the color harmony score of local images
to solve the problem of the lack of the reference images, and finally a
quality assessment module is designed to fuse global natural statistical
features and local spatial features to evaluate color fusion images.
Experimental results demonstrate the promising performance of the
proposed method.
