Fault feature extraction and fusion method for AUV with weak thruster fault based on variational mode decomposition and D-S evidence theory
Authors: Yu Dacheng , Zhang Mingjun , Liu Xing , Yao Feng
Published: June 2022

This study investigated the fault feature extraction and fusion problem for autonomous underwater vehicles with weak thruster faults. The conventional fault feature extraction and fusion method is effective when thruster faults are serious. However, for a weak thruster fault, that is, when the loss of effectiveness of thrusters is less than 10%, the following two problems occur if the conventional method is used. First, the ratio of fault features to noise features is small. Second, there is no monotonic relationship between the fusion fault features fused by the conventional method and the fault severity. In this paper, the following two methods are proposed to solve this problem: 1) Fault-feature extraction method. Based on negentropy, this method improves the evaluation index of the parameter optimization of the modified variational mode decomposition and finally enhances the fault features extracted by the modified Bayesian classification algorithm. 2) Fault-feature fusion method. To create a monotonic relationship between the fusion fault features and fault severity, this method expands the number of original signals of the traditional fusion method based on D-S evidence theory, improves the focus element of the traditional fusion method, and adopts the strategy of double fusion. Finally, the effectiveness of the proposed method was verified by pool-experiment results on Beaver II prototype.

Published: June 2022

During the past few years, freelancing has grown exponentially due to the pandemic and subsequent economical changes in the world. In fact, in the last ten years, a drastic increase in freelancing has been observed; people quit their jobs to be their own boss. There are various reasons for this: downsizing of employees, not having fun in their jobs, unemployment, part time work to earn more, etc. Observing this vast change, many individuals on Facebook/YouTube, NGOs, and government departments started teaching freelancing as a course; to date, thousands of youngsters have been trained to start their careers as freelancers. It has been observed that the ratio of informed freelancers is more successful than those who start their careers independently. We construct a compartmental model to explore the influence of information on the expansion of freelancing in this article, which was motivated by this surge in freelancing. Following that, the model is subjected to dynamical analysis utilizing dynamical systems and differential equation theory. To validate our analytical conclusions, we used numerical simulation.

Published: June 2022

Despite the technological advancements in neuroimaging and physiological technologies, studies about using this technology to study the neural correlates of consumers' behavior toward external stimuli remain unclear in the academic literature. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework in this article to select relevant articles for this study. We extracted and analyzed fifty-six articles from the Web of Science (WoS) database to answer the research questions. We found eight common methods, as follow: (i) neuroimaging tools such as fMRI, fNIRS, and EEG used to study the neural responses of emotional and cognitive processes, (ii) physiological tools such as ET, EMG, GSR, ECG, and IAT to study eye movements, fixation, pupil dilation, consumers’ attitudes, visual attention, heart rate, zygomatic and corrugator facial muscles toward environment stimuli such as machines. We hope this article provides valuable insights into neuroimaging and physiological technology guiding new practitioners and researchers to choose the appropriate tool to conduct the experiment and get high-quality and reliable results.

Using content analysis, we have determined the research hotspots of the scientific publications during the past five years
ECG Signal Analysis for Automated Cardiac Arrhythmia Detection
Authors: Jha Chandan Kumar
Published: June 2022

The graphical recordings of electrical stimuli generated by heart muscle cells are known as an electrocardiogram (ECG). In cardiology, ECG is widely used to detect different cardiovascular diseases among which arrhythmias are the most common. Irregular heart cycles are collectively known as arrhythmias and may produce sudden cardiac arrest. Many times, arrhythmia evolves over an extended period. Hence, it requires an artificial-intelligence-enabled continuous ECG monitoring system that can detect irregular heart cycles automatically. In this regard, this chapter presents a methodological analysis of machine-learning and deep-learning-based arrhythmia detection techniques. Focusing on the state of the art, a deep-learning-based technique is implemented which recognizes normal heartbeat and seven different classes of arrhythmias. This technique uses a convolutional neural network as a classification tool. The performance of this technique is evaluated using ECG records of the MIT-BIH arrhythmia database. This technique performs well in terms of different classification metrics.

Authors: Ferrah Aek , Bouaziz Amina Manel , Bouaziz M.N.
Published: June 2022

This paper deals with natural thermal convection combined with the mass transfer of nanoparticles occurring in the boundary layers of a nanofluid subjected to magnetohydrodynamics. The wall consists of an inclined plate is considered according to a temperature as well as the volume fraction of the nanoparticles varying as the power of the axial coordinate. In addition, internal heat generation/absorption is taken into account in the mathematical formulation. The governing partial differential equations based on Buongiorno's approach are transformed into a set of ordinary differential equations. The two-level method of no-similarity equations is used to achieve higher accuracy. The whole calculation procedure is implemented using a limit value problem program written according to the Matlab computer language that applies the Lobbato IIIa finite difference method. The obtained results have revealed that small variations of the boundary conditions with the axial coordinate become very significant on the local Nusselt number and the local Sherwood number for nanoparticles. Moreover, a better heat transfer has been obtained with a larger S. However, a trade-off between desired heat transfer rate and level of reduced skin friction should be scheduled.

Published: June 2022

This article deals with the problematics of the production of small castings using gravitational investment casting. These are castings with a relatively complex shape, which are used as parts of trigger assembly for musical wind instruments. During their production, various defects occur which are connected with the casting process. The aim of this article is to describe the defects and suggest possible methods for removing them. The first step was to find and identify these defects using metallographic and EDX microanalysis. Furthermore, a simulation calculation of the casting process was used to determine the influence of the casting geometry on casting quality. Based on these analyses, the most suitable alloy and casting system geometry were proposed for the production of the casting.

Authors: Rizza Giovanni , Galati Manuela , Iuliano Luca
Published: June 2022

The partial sinter between the powder particles during the electron beam – powder bed fusion (EB-PBF) process is fundamental to guarantee adequate thermal and electrical conductivities and conduct the process safely. The sintering degree is tuned by using the process parameters that, at the present day, are mainly optimised with an experimental trial and error approach. Simulation has proven the capability to reduce costs and time related to parameter optimisation. In the current work, a phase field model was developed to simulate sintering during the EB-PBF process. The novelty lies in simulating the sintering process under non isothermal conditions which emulate the heating of the powder due to the preheating and subsequent temperature decrease due to the layer additions. The results show a strong influence of the thermal history on the neck growth and dimension, which differ significantly with respect to the traditional approach to the sintering simulation which considers only constant temperature.

Published: June 2022

Significant demand of Li-ion batteries (LIBs) is raising awareness of future LIBs wastes which are highly required to be reprocessed, reused or recycled. In this research, copper foil waste from spent LIBs are upcycled as an anode material, CuO. Hydrometallurgical route was applied to selectively dissolve copper foils where nitric acid, maleic acid and acetic acid were used as the leaching agents while oxalic acid were used to precipitate copper into copper oxalate which is a precursor to CuO. CuO was obtained by calcination of copper oxalate at high temperature. Based on XRD and FTIR analysis, Copper (II) oxalate dihydrates is successfully obtained while SEM images of the samples confirmed micron sized agglomerates which is consist of submicron primary particles. XRD analysis of CuO samples obtained from various leaching process confirmed that a pure CuO is successfully synthesized from nitric acid leaching process while CuO from acetic acid and maleic acid leaching has Cu2O and Cu phase. CuO and 10%CuO@graphite sample from nitric acid leaching were used as sole anode and composite anode in a LiNi0.8Co0.1Mn0.1O2(NCM) battery, respectively. The initial columbic efficiency of CuO anode was far inferior to CuO@graphite. However, CuO@graphite had higher specific charge-discharge capacity with the value of 347.8 mAh/g compared to pure graphite (286.5 mAh/g). In conclusion, Cu-foils are a promising source of CuO to enhance the capacity of commercial graphite anode.

Published: June 2022

In the present study, feasibility of micro-plasma transferred arc (M-PTA) for flank surface treatment of gears has been explored. 20MnCr5 spur gears manufactured by sustainable technique minimum quantity lubrication assisted hobbing (MQLAH) were subjected to M-PTA-based heat treatment for further improving the surface properties of flank surface and comparisons were made with respect to M-PTA treated gears machined by conventional flood lubrication assisted hobbing (FLAH). The results revealed that M-PTA enhanced flank surface hardness of all the gears without deteriorating the gear accuracy. However, flank hardness increment was observed to be almost 18% in case of MQLAH gears as compared to 15% for FLAH gears. This study proves that M-PTA based heat treatment after MQLAHcan result in superior surface hardness along with better gear accuracy and can improve the sustainability of overall process chain involved in machining-based gear manufacturing.

Published: June 2022

A temperature stress testing machine (TSTM) was used to investigate effect of cement composition and temperature history on thermal stress of concrete. Results show that the benefit of higher amount of C3S on concrete strength enhancement was compromised by the relatively higher temperature rise at early age, leading to a lower temperature difference. However, by means of a delicate design of cooling history, the deficiency of concrete with higher amount of C3S can be compensated and the cracking sensitivity was closer to that of concrete with lower amount of C3S.

Authors: Minh Pham Son , Huynh Do Song Toan , Son Tran Anh
Published: June 2022

Three-dimensional (3D) printing is a method of additive manufacturing that involves creating objects by serial deposition for pre-production or production. After designing a 3D model with a CAD program, a processable file is customized to create a layered design, which is then printed. Although this technique costs more than traditional techniques, such as metal injection molding, metal 3D printing can significantly improve the production times of lightweight parts produced in small numbers. Furthermore, is improves flexibility, and is more able to produce complicated geometries that would not be possible with common methods, such as turning, milling or drilling. The fused deposition modeling technique uses a metal powder filament, which is pulled through a high-temperature extrusion nozzle, thus melting the material; after that, the printed parts are placed in the debinding station with a solvent to remove the wax from the powder. Finally, completed products are taken from the sinter furnace with inert gases. Depending on the material, different characteristics arise in the production process, and the produced parts manifest different mechanical properties. This paper describes some experiments performed on the fused deposition modeling method using stainless steel filaments, debinding Opeteon and a sinter furnace.

Published: June 2022

Modification of nanometer size order in anode material of hematite nanoparticles is believed to be one of the keys to increasing the specific capacity of Li-ion batteries application. So that, the synthesis temperature dependence of nanocrystallite size properties in co-precipitated hematite nanoparticles is studied. Sample of Hematite nanoparticles is modified the physical properties by synthesis temperature and then annealed of 700°C for 4 hours. The crystallite size increase with the increase of the synthesis temperature i.e., 23.06 to 29.64 nm. It is indicated that the synthesis temperature affects crystallite formation. Furthermore, the magnetic properties show that the coercive field decrease from 869 to 211 Oe with the increase of the temperature synthesis. It is related to the change in the nanosize-order of the sample crystallite.

Published: June 2022

Lithium iron phosphate (LiFePO4) batteries have received much attention because they can provide higher power density with abundant raw materials, better safety, low toxicity, and high thermal stability. In general, the production of LiFePO4 cathodes uses polyvinylidene fluoride (PVDF) as a binder and N-methyl-2-pyrrolidone (NMP) as a solvent. These components are expensive, toxic, and can adversely affect the environment. Therefore, to address these shortcomings, the solvent and binder were replaced in this study. The solvent in the current study is water. The water soluble binders employed in this study are carboxymethyl cellulose (CMC) and styrene-butadiene rubber (SBR). Suitable electrode formulations were investigated to obtain high performance cylindrical Li-ion batteries. As a result, a formulation with a ratio of LiFePO4:AB:KS6:SBR:CMC equal to 90:3:3:2.677:1.333 was used. It has a high specific discharge capacity, 120 mAh/g. This NMP-based cathode can yield about 145 mAh/g, which is slightly higher than a water-based LiFePO4 cathode.
Optimal Control Strategy for Energy Management of PV-Diesel-Battery Hybrid Power System of a Stand-Alone Micro-Grid
Authors: Gbadega Peter Anuoluwapo , Balogun Olufunke
Published: June 2022

New control algorithms are required to deal with the intermittent, stochastic, and distributed nature of the generation and new consumption patterns. Control of micro-grids poses significant challenges that need to be addressed through advanced control techniques. This paper investigates an optimal control strategy that efficiently manages a stand-alone residential micro-grid comprising renewable and non-renewable energy sources. An adaptive model predictive control (AMPC) algorithm is implemented for choosing an optimal mode and set of inputs for the system to track both a constant and load-varying power demand profile. The problem to be solved by the AMPC control algorithm is to perform an optimal power reference tracking problem, where the consumption of energy from the diesel generator is minimized while maximizing the efficiency of the storage bank. The objective of the optimal control scheme is for the generation to meet the demand, minimize the use of fossil fuels and ensure the energy storage is always maintained around a nominal point such that it is not over-depleted. Therefore, the main goal is to maximize the use of renewable sources and minimize traditional sources. The design and simulation of the plant model and the AMPC controller are carried out on the MATLAB/Simulink environment.
Analysis of a Damaged Drill Made from Hs 2-9-1-8 Steel
Authors: Průcha Vojtěch , Bricin David , Hájek Jiří
Published: June 2022

This article aims to explain the reasons leading to the damage of a drill during its final grinding. Metallographic analysis using light and scanning electron microscopy was used to determine whether the damage was related to the structure of the material, which is given by its chemical composition, forming, and especially its heat treatment, or the grinding methodology. The drill was made of HS 2-9-1-8 tool steel. Fractographic analysis showed a cleavage fracture. In terms of the heat treatment used, the measured hardness of the analysed samples was appropriate for the requirements and possibilities of the tool steel. The metallographic analysis showed that the microstructure contained areas with clusters of primary carbides. These clumps significantly reduce the toughness of the material. In addition, there was a structural notch in the form of a white layer with a higher carbon content on the outer circumference of the samples. This layer also significantly contributed to the reduction of toughness. The hardened layer below the structural notch also contributed to the reduction in toughness. All of these microstructural defects were caused by poor grinding, which led to damage to the tool.

Published: June 2022

Ultrasonic Vibration-Assisted Machining (UVA) is a machining process that adds a micro-scale high frequency vibration to the motion of a cutting tooltip to interrupt the continuous interaction of tool - workpiece surface. A good point of machining with UVA is more effective than conventional processes such as lower machining forces, higher machining stability, less tool wear and better surface finishes. In molds fabrication with some narrow cavities having a conversion space diameter of less than 3mm will face many difficulties while low surface roughness is required. Low stiffness of technological system in these cases of finishing machining is the reason of a weak machining in high-speed cutting. The ability to achieve cutting speeds for surface finishing of this type in tight spaces is also an interesting application for UVA tools. This paper discusses the finishing machining tool design with UVA for milling machine in such as analyze of the main parameters, adding diagonal split and simulation of the generated vibration effects to evaluate the achieved results before fabrication by using the help of ANSYS.

Published: June 2022

COVID-19 can affect multiple organs, including skin. A wide range of skin manifestations have been reported in literature. Six main phenotypes have been identified: i) urticarial rash, ii) confluent erythematous/maculopapular/morbilliform rash, iii) papulovesicular exanthem, iv) a chilblain-like acral pattern, v) a livedo reticularis/racemosa-like pattern, and vi) a purpuric vasculitic pattern. The pathogenetic mechanism is still not completely clear, but a role of hyperactive immune response, complement activation and microvascular injury have been postulated. The only correlation between the cutaneous phenotype and the severity of COVID-19 has been observed in the case of chilblain-like acral lesions, that is generally associated with the benign/subclinical course of COVID-19. Herein, we report two cases of SARS-CoV- 2 infection in patients who developed cutaneous manifestations that completely solved with systemic steroids and antihistamines. The first case is a female patient not vaccinated for SARS-CoV-2 with COVID-19 associated pneumonia, while the second case is a vaccinated female patient with only skin manifestations.

We describe the case of a 78-year-old woman admitted to our emergency department for an acute onset of severe dyspnoea with inspiratory wheezing-like sounds. She denied fever, cough, voice change and pain. She referred a similar but less severe episode occurred spontaneously one year before, with complete resolution in few minutes without sequelae. On examination upper airway obstruction was firstly excluded. She was initially treated as having asthma, without response. Parenteral high dose corticosteroids and antihistamines provided no benefit. Point-of-care-ultrasound resulted normal. Flexible laryngoscopy during the episode showed paradoxical vocal cord movement with adduction during both inspiration and expiration. This demonstrated that her dyspnoea was from Vocal Cord Dysfunction (VCD). VCD completely solved after administration of intravenous benzodiazepines.

Knee Osteoarthritis (OA) is a highly prevalent condition affecting knee joint that causes loss of physical function and pain. Clinical treatments are mainly focused on pain relief and limitation of disabilities; therefore, it is crucial to find new paradigms assessing cartilage conditions for detecting and monitoring the progression of OA. The goal of this paper is to highlight the predictive power of several features, such as cartilage density, volume and surface. These features were extracted from the 3D reconstruction of knee joint of forty-seven different patients, subdivided into two categories: degenerative and non-degenerative. The most influent parameters for the degeneration of the knee cartilage were determined using two machine learning classification algorithms (logistic regression and support vector machine); later, box plots, which depicted differences between the classes by gender, were presented to analyze several of the key features’ trend. This work is part of a strategy that aims to find a new solution to assess cartilage condition based on new-investigated features.

ALLA RICERCA DI UNA SFERA DI INFLUENZA IN ASIA: LA POLITICA ITALIANA IN AFGHANISTAN TRA LE DUE GUERRE (1919-1928)
Authors: Casolari Marzia
Published: June 2022

L’Afghanistan, dal 2001 al centro della politica internazionale, ha acquisito ulteriore rilevanza a seguito del ritiro del contingente NATO nell’ agosto 2021, dopo esattamente vent’anni di presenza nel paese. Fra le nazioni che hanno aderito alla coalizione, l’Italia ha svolto un ruolo di primo piano: la funzione del nostro paese si è concentrata sulla ricostruzione, soprattutto istituzionale e dei servizi rivolti alla popolazione. È evidente che il governo italiano ha messo in campo un notevole investimento in Afghanistan, in termini di persone impiegate, ma soprattutto in termini economici. A riprova dell’importanza della presenza italiana nel paese è la richiesta da parte del portavoce dei talebani, Zabiullah Mujahid, il 1 settembre 2021, di non chiudere l’Ambasciata d’Italia a Kabul1. Sorge spontaneo chiedersi da dove derivi l’importanza dell’Afghanistan per l’Italia, che si è così a lungo e tanto spesa in questo paese, e quale sia l’importanza dell’Italia per l’Afghanistan, al punto che da un esponente di primo piano di un governo non certo benevolo vero l’Occidente arrivi una simile richiesta. Una ricostruzione delle origini della presenza italiana in Afghanistan potrà aiutare a fornire risposte a questo quesito, in una prospettiva storica. Questo articolo abbraccia un arco cronologico che va dalle prime iniziative avviate in Afghanistan fin dalle fasi conclusive del quinto governo Giolitti, nella primavera 1921, alla vigilia della caduta di re Amanullah Khan e del suo esilio in Italia, nel 1929. Questa vicenda ha rappresentato uno spartiacque sia nella storia dell’Afghanistan, sia nella politica italiana in questo paese. Amanullah Khan fu il primo fra i regnanti e i capi di stato afghani a cercare di introdurre importanti riforme modernizzatrici. Nonostante questo tentativo sia in gran parte fallito, il regno di Amanullah ha segnato un’epoca e ha lasciato un segno profondo nella memoria storica dell’Afghanistan. Questo saggio si ferma alla vigilia degli anni Trenta, quando la politica italiana nella regione compresa tra Asia centrale e meridionale era ancora di cauta esplorazione e di interlocuzione con la Gran Bretagna.
TRE STUDI SU LEO STRAUSS. UNA RASSEGNA CRITICA
Authors: Ghibellini Alberto
Published: June 2022

A conferma dell’importanza dell’autore, la letteratura critica su Leo Strauss, in Italia e all’estero, non ha fatto che crescere negli ultimi anni. Dopo una parentesi contrassegnata da un’impronta marcatamente ideologica (più contra che pro) delle interpretazioni del suo pensiero, oggi si assiste, in generale, ad un ritorno alla sobrietà e al distacco di letture che si sforzano soprattutto di capire Strauss, al di là dei motivi soggettivi per apprezzarne o rifiutarne le concezioni. Il proposito di questo articolo è discutere alcuni sforzi interpretativi recenti che si distinguono per ampiezza, rilevanza e originalità. Si tratta, in particolare, di tre monografie – Una filosofia in esilio. Vita e pensiero di Leo Strauss (Carocci, Roma, 2021) di Carlo Altini, Leo Strauss tra Husserl e Heidegger. Filosofia pratica e fenomenologia (Edizioni ETS, Pisa, 2018) di Pierpaolo Ciccarelli e Leo Strauss (Polity Press, Cambridge, 2021) di Neil G. Robertson – che risultano caratterizzate da un approccio organico alla riflessione straussiana e dall’ambizione di fornirne un’interpretazione esaustiva e coerente, almeno nelle sue linee fondamentali. Nel prosieguo di questo articolo si cercherà di mostrare con quali risultati, avendo cura, soprattutto, di evidenziare le questioni, tra le molte meritoriamente sollevate, che risultano a nostro avviso ancora aperte.
TRAME DEL RICONOSCIMENTO: DA HEGEL ALL’IDENTITÀ DI GENERE
Authors: Di Donato Giulio
Published: June 2022

La prevenzione e il contrasto alle discriminazioni e alla violenza per motivi fondati sul sesso, sul genere e sull’orientamento sessuale rappresentano un’esigenza sentita in maniera ormai trasversale e allo stesso tempo un tema oggetto di polemiche infuocate nel momento in cui si passa dal piano della petizione di principio al piano della traduzione normativa (se ad esempio si tratta di modificare gli articoli 604 bis e ter del Codice penale e la successiva legislazione in materia di istigazione a delinquere, equiparando la discriminazione per i motivi di cui sopra a quella su base razziale, etnica o religiosa). Polemiche che hanno reso e rendono assai difficile intavolare una discussione laica e ragionata sul merito, al di là degli opposti isterismi e delle opposte strumentalizzazioni. In questa sede, lontani dalla concitazione del dibattito più acceso e fanatico, proveremo a riflettere sulle implicazioni di carattere filosofico-giuridico che l’eventualità di un intervento normativo in materia solleva: dalle definizioni di sesso e di genere all’equilibrio fra salvaguardia della libertà di opinione e lotta alle discriminazioni, per soffermarci infine sulla contraddizione fra le istanze soggettivistiche e contingenti alla base del concetto di identità di genere (comunemente definita l’identificazione percepita e manifestata di sé in relazione al genere, anche se non corrispondente al sesso, indipendentemente dall’aver concluso un percorso di transizione) e i criteri di oggettività e stabilità che sono propri della dimensione giuridica e in particolar modo della norma penale.

With the developing digital technologies, pre-production, production, post-production, distribution and screening stages in cinema are changing and developing. This leads to changes in the position of the audience. Since the movies are watched collectively in movie theaters in the era of conventional production, the cinema experience is not individual but social. However, with digitalization, the audience started to watch the movies at home. Cinema is now moving towards an individual viewing culture rather than a social one. In the late 1970s, viewers had the opportunity to watch movies whenever and wherever they wanted via videotapes. However, there are problems with watching movies with some parts cut off due to the inaccessibility of every movie and the current controls. In the 1990s, thanks to the developing CD-Rom technologies, anyone who had a computer was able to have their own personal cinema. In the 2000s, with the developing internet technologies, the audience had the opportunity to access almost any movie they wanted. The desired movies can be accessed through computers, tablets and mobile phones, even during travel. In recent years, three-dimensional and interactive films have also met with the audience. Thus, viewers can intervene in digital films and re-edit them as they wish, thanks to the developing computer technologies.
