Chaos Suppression Occurred in Spur Gear Mechanism by Reset Control

Mechatronics equipment are required to control the response of machines at high speed and with high accuracy. However, many machines include pinion stands, gear couplings, etc., and there are some roles in the transmission part. When the response of these machines is increased, chaos phenomenon occurs due to the backlash, which is an obstacle to high speed and high accuracy. In this study, we show the result that suppresses the chaos to the gear transmission system by applying the reset control by simulation.
UFCNet: U-shaped Fully Connected Network for Improving Direction of Arrival Estimation Accuracy in Electronic Intelligence Systems

In practical applications, it is crucial to eliminate errors, which are significantly introduced in the estimation of the direction of arrival (DOA) by the presence of array defects such as element position errors or phase/gain inconsistencies. This paper proposes a U-shaped deep neural network called UFCNet, which employs fully connected layers exclusively, to automatically calibrate the phase and amplitude errors present in the covariance matrix. The output of UFCNet is a nearly ideal covariance matrix, which is then utilized by the MUSIC or rootMUSIC algorithms to accurately estimate the DOA of signals. Simulation results demonstrate that UFCNet effectively mitigates phase and amplitude errors, thereby providing a nearly perfect covariance matrix for the rootMUSIC algorithm to estimate the DOAs of incoming signals with high precision. In comparison to other traditional methods, the combination of UFCNet and rootMUSIC achieves the best performance in terms of DOA estimation accuracy.
Performing the ‘global citizen’ in social imaginaries: the value of intercultural exchange for Australian students in Mexico

ABSTRACT Due to the recent increase in Australian students undertaking study abroad opportunities, an effect of a neoliberal society, there has been a plethora of literature in this area with the extant literature focusing on students’ motivations and subsequent benefits of exchange. This paper examines how the capital acquired during intercultural experiences are performed by Australian exchange students. Interviewed before, during, and after Mexican sojourns, the students initially (re)produced a stylised pastiche of ‘Mexico’. Made in urban Australia, this imaginary comprises Frida-Kahlo themed restaurants and Day-of-the-Dead exotica. As a result of geographic distance and limited migration from Mexico, Mexicanidad in Australia operates as a vacant conceptual category into which ‘cool’ yearnings can be inscribed. Despite problematising their pre-departure constructions at times, the students continued to employ this version of Mexicanidad in their performance of the role of Mexican expert, in Mexico and on their return. This article theorises the functions of such identity performances, proposing that exchange experiences, and the intercultural capital they acquire, serve as a method by which students can construct and perform transnational identities.
A Spurious-Free Piezoelectric Resonator Based 3.2 kW DC–DC Converter for EV On-Board Chargers

Piezoelectric power conversion has emerged as a promising technology for power-dense, efficient dc–dc conversion absent of magnetic components for energy storage. However, two practical challenges of piezoelectric devices have limited prototype demonstrations to relatively low power. First, spurious resonant modes plague low impedance resonator design, restricting operating load range, and lowering efficiency. Second, the mechanical nature of piezoelectric energy storage prevents traditional methods of removing heat. This work presents a spurious-free piezoelectric resonator design and a FOM for measuring a power resonator's spurious modes. Additionally, this work develops thermal enhancements at both the piezoelectric device and converter level to improve heat extraction. These advances in acoustic and thermal performance overcome the challenges for moving piezoelectric power conversion to high power, demonstrated by a paralleled piezoelectric dc–dc converter capable of outputting 3.2 kW at 97.7% efficiency, and a piezoelectric resonator achieving a component power density of 5.7 kW/cm$^{3}$.
Tomographie acoustique océanique en guide d'ondes : de l'utilisation des temps à celle des angles

Dans l'ocean, les changements de temperature induisent des perturbations de la vitesse de propagation des ondes acoustiques. La tomographie acoustique oceanique utilise les fluctuations de signaux acoustiques enregistres pour cartographier ces perturbations de vitesse du son. Cette etude propose une methode alternative utilisant la direction de propagation des ondes acoustiques (plutot que les temps de propagation utilises classiquement) pour imager un guide d'onde oceanique peu profond (~100 m), petite echelle (1 a 10 km), avec une haute resolution spatiale (10 m horizontalement, 2 m en profondeur). Dans ce contexte, les ondes acoustiques basse frequence (~1 kHz) a large bande spectrale (~1.5 kHz) se propagent selon des trajectoires multiples assimilables a des rayons geometriques epais spatialement. L'utilisation d'un couple d'antennes (emission/reception) et de la double formation de voies permet de separer les signaux en provenance des differents trajets acoustiques et de mesurer leur : temps de propagation (TP), direction d'arrivee (DA) et direction de depart (DD). Dans l'hypothese de faibles perturbations, les variations des TP, DA et DD sont reliees lineairement aux perturbations de la distribution de vitesse du son de maniere analytique. Cette formulation, basee sur la physique de la diffraction de Born au 1er ordre, utilise des fonctions noyaux appelees : noyaux de sensibilite temps-angles (NSTA). Les methodes classiques d'inversion permettent alors de retrouver les perturbations de vitesse a partir des variations de TP, DA et DD en utilisant les NSTA. Les methodes developpees ont ete validees sur donnees simulees, puis appliquees a des donnees reelles d'experiences a echelle reduites realisees dans la cuve ultrasonore de l'ISTerre, Grenoble.
Differential-Fed Dual-polarized Dual-band Stacked Patch Antenna Using Multi-Resonances

A differential-fed dual-polarized dual-band stacked microstrip patch antenna is proposed for 2.45-GHz and 3.5-GHz applications. The design is composed of a double differential-fed slotted patch for dual-polarization and unidirectional radiation pattern. The antenna utilizes $TM_{10}$ mode for the low-band operation. Four rectangular slots are introduced to create an extra resonance in the upper-band while a stacked patch with four vias is implemented to further broaden the high-band operating bandwidth. With the combination of differential-fed scheme and symmetric structure, the proposed antenna yields very high isolation of $\geq$ 40 dB. The fabricated prototype with a profile of 0.09$\lambda_{2.45-GHz}$ obtains a measured 10-dB return loss bandwidth of 2. 42-2.52 GHz and 3. 21-4.12GHz. The simulated results also show highly symmetrical patterns and low cross-polarization in all operating frequencies for both differential-port operation.
A systematic review of the prevalence and risk factors for adverse drug reactions in the elderly in the acute care setting

: Adverse drug reactions (ADRs) are an important health issue. While prevalence and risk factors associated with ADRs in the general adult population have been well documented, much less is known about ADRs in the elderly population. The aim of this study was to review the published literature to estimate the prevalence of ADRs in the elderly in the acute care setting and identify factors associated with an increased risk of an ADR in the elderly. A systematic review of studies published between 2003 and 2013 was conducted in the Cochrane Database of Systematic Reviews, EMBASE, Google Scholar and MEDLINE. Key search terms included: “adverse drug reactions”, “adverse effects”, “elderly patients and hospital admission”, “drug therapy”, “drug adverse effects”, “drug related”, “aged”, “older patients”, “geriatric”, “hospi-talization”, and “emergency admissions”. For inclusion in the review, studies had to focus on ADRs in the elderly and had to include an explicit definition of what was considered an ADR and/or an explicit assessment of causality, and a clear description of the method used for ADR identification, and had to describe factors associated with an increased risk of an ADR. Fourteen hospital-based observational studies exploring ADRs in the elderly in the acute care setting were eligible for inclusion in this review. The mean prevalence of ADRs in the elderly in the studies included in this review was 11.0% (95% confidence interval [CI]: 5.1%–16.8%). The median prevalence of ADRs leading to hospitalization was 10.0% (95% CI: 7.2%–12.8%), while the prevalence of ADRs occurring during hospitalization was 11.5% (95% CI: 0%–27.7%). There was wide variation in the overall ADR prevalence, from 5.8% to 46.3%. Female sex, increased comorbid complexity, and increased number of medications were all significantly associated with an increased risk of an ADR. Retrospective studies and those relying on identification by the usual treating team reported lower prevalence rates. From this review, we can conclude that ADRs constitute a significant health issue for the elderly in the acute care setting. While there was wide variation in the prevalence of ADRs in the elderly, based on the findings of this study, at least one in ten elderly patients will experience an ADR leading to or during their hospital stay. Older female patients and those with multiple comorbidities and medications appear to be at the highest risk of an ADR in the acute care setting.
Autonomous Vehicle

In 2015, there were about five lakhs road accidents in India, which killed about 1.5 lakhs people and injured about five lakhs people.18% of which happened due to lack of driver consciousness and 11% due to speeding, all of these would have been avoided at the first place if there was a more automated law obeying system. This is where the need of self driving car comes into picture which is completely automated and significantly reduces the death ratio due to accidents. <br>
NOVEL BOUNDARY INTEGRAL METHOD FOR SLOW FREE SURFACE FLOWS

The present article introduces a novel boundary integral method (BIM), adapted from an earlier method of Hansen and Kelmanson (1992, 1994) and suitable for the solution of creeping ﬂow boundary value problems where the boundary presents singularities in the stresses. We use the new BIM to solve the problem of the planar extrusion of a Newtonian ﬂuid at zero Reynolds number and, in particular, to determine the shape of the free surface in the immediate neighbourhood of the separation point for a range of capillary numbers. The proposed method incorporates the singular solution near the separation point, thus overcoming one limitation of a classical BIM to the problem (see, for example, Kelmanson (1983)). In a recent article, Owens (2022) also incorporated the singular solution into his BIM formulation. However, since the integration path used in the present BIM passes directly through the separation point this leads to an important improvement on the method of Owens (2022), who was obligated to skirt the singularity due to the non-integrability there of the normal derivative of the vorticity. Results presented for the extrudate swell ratio, the angle of separation and the leading exponent in the asymptotic expression for the stream function are shown to be in convincing agreement with others in the theoretical, numerical and experimental literature.
Controller Design for Heave and Surge Motions for AUVs

In this paper, we constructed a simulation block for an underwater vehicle using the MATLAB Simulink tools. The equation of motion and parameters are referred from the MIT Autolycus. First, the step responses are checked to see the correctness of the model. Then the linear models for heave and surge motions are obtained using the system Identification tool in MATLAB Simulink using the step responses from the nonlinear model. A 2-degree-of-freedom PID controller is designed, and the performance and stability margins of the control loops are analyzed. It is found that both controllers have big gain margins and 69-degree phase margins. The bandwidths of the surge control loop and heave control loop are both 2 rad/sec. Both step responses show that the steady-state errors and maximum overshoot are small. We checked the linearly obtained controller on the nonlinear plant model and the results are good enough.
Prevalence and risk factor of anemia among pregnant women admitted in antenatal ward in PBMH Bhubaneswar, Odisha

Background: Anemia is one of the contributing factors for morbidity and mortality during pregnancy in developing country including India, which eventually leads to fetal and maternal consequences. Growing fetus depends completely on mothers for all its growth and maturity. Anemia is one of the nutritional deficiency disorders and around 56% of women are suffering from anemia in India. It is one of the reasons for maternal deaths and fetal complication during pregnancy. Aim: The aim of the study was to assess the prevalence of anemia and to determine the risk factors of anemia among pregnant women in PBMH hospital, Bhubaneswar, Odisha. Materials and Methods: A descriptive cross-sectional study was conducted over a period of 1 month from October 11, 2022, to November 11, 2022, from the Department of Obstetrics and Gynecology of Pradyumna Bal Memorial Hospital KIMS, Bhubaneswar. A total sample comprised of 52 pregnant women who were interviewed by using self-structured questionnaire for data collection and classification of anemia was performed according to the Indian Council of Medical Research (ICMR) criteria. Results: A total of 52 antenatal mothers were admitted during this study period (October 11, 2022, to November 11, 2022), and all were selected as study sample. The incidence of anemia among antenatal mother in PBM hospital was found as follows: 17 (33%) mild, 04 (07%) moderate, and 02 (04%) were severe in this present study. The most common indication of anemia among antenatal mother as per the present study was found to be H/O infection (21%), chronic malaria (15%), hook worm (27%), and birth interval (42%). Conclusion: The study implies that the prevalence rate of Anemia is high, that is, 44.2%. Spacing between pregnancy and H/O infection plays a significant role in considering anemia in pregnant women, which eventually affects both maternal and fetal condition.
Imaging Ultrasound Scattering Targets using Density-Enhanced Chaotic Compressive Sampling

The ultrasound imaging method is a highly promising technique used in various fields. The utilization of ultrasound technique's backscattering could also allow humans to observe objects as small as the size of the incident wavelength. However, the employing backscattering approach requires high computational calculations and poses a significant obstacle to the production of equipment using the ultrasonic method. In this work, we utilized the pseudo-random compression sampling method in the extended DBIM model, which takes tissue density factor. This is necessary because tissue density provides quantitative information about soft tissue and serves as an image contrast source. This method combines pseudo-random measurement and compressed sensing data recovery technique. The simulation results have proved the effectiveness of the proposed CCS-DBIM method. In terms of imaging quality, at compression ratios as low as 0.5, the large difference in imaging quality is evident. After 5 iterations, the normalization error of the DBIM and CCS-DBIM methods was 0.8828 and 0.5281 respectively, i.e. a 40% reduction in normalization errors when the number of measurements was only half of the variables. The disadvantage of the proposed CCS-DBIM method is that the imaging time is significantly greater than that of the DBIM method. However, with today's parallel computing technology, large amounts of data and computational time will no longer be a big problem.
Integrated Rearrange Processing of Hybrid Model with Weighted Values for PM2.5 Forecasting

This paper suggests using the integrated two hybrid models, ARIMA-LSTM and LSTM-ARIMA forecasting model, with weighing values for PM2.5 forecasting. The dataset, PM2.5 data of Bangkok, included wind direction (WD), wind speed (WS), temperature (Temp), and particulate matter 2.5 (PM2.5) for hourly data updated. The experiment results found that two hybrid models forecasting by ARIMA-LSTM & LSTM-ARIMA with then adjusting the weights ratio can predict the lower error when comparing forecasting with the other algorithms. Specifically, forecasting by a set of hybrid models with an LSTM Univariate Variable.
Association Between Maternal Mood Disorders and Schizophrenia and the Risk of Type 1 Diabetes in Offspring: A Nationwide Cohort Study

Objective Our study aimed to determine whether mothers with bipolar disorder, major depressive disorder, schizophrenia, or schizoaffective disorder affected the risk of type 1 diabetes (T1D) in their offspring. Methods We conducted a nationwide cohort study by using data from Taiwan’s National Health Insurance Research Database and the Maternal and Child Health Database from 2004 to 2018. A total of 2,556,640 mother-child pairs were identified. Cox proportional hazards models were used to compare the risk of T1D between children born to mothers with mood disorders and schizophrenia and those without. Results No significant difference in risk of T1D was observed between the offspring of mothers with major psychiatric disorders and those without (adjusted hazard ratio (aHR) of 0.86 with a 95% confidence interval (CI) of 0.58–1.24). In subgroup analysis, we found an aHR of 1.81 with a 95% CI of 0.83–3.82 in the maternal bipolar disorder on the risk of T1D in offspring and an aHR of 0.87 (95% CI: 0.59–1.25) in maternal major depressive disorder. In the schizophrenia/schizoaffective disorder group, aHR cannot be obtained due to lesser than three events in the analysis. Conclusion The risk of T1D in offspring of mothers with mood disorders and schizophrenia was not significant. However, children born to mothers with bipolar disorder may have a tendency to develop T1D. The relationship between maternal psychiatric disorders and the risk of T1D in offspring warrants further investigation in studies with longer follow-up periods.
Assessment, patient selection, and rehabilitation of nerve transfers

Peripheral nerve injuries are common and can have a devastating effect on physical, psychological, and socioeconomic wellbeing. Peripheral nerve transfers have become the standard of care for many types of peripheral nerve injury due to their superior outcomes relative to conventional techniques. As the indications for, and use of, nerve transfers expand, the importance of pre-operative assessment and post-operative optimization increases. There are two principal advantages of nerve transfers: (1) their ability to shorten the time to reinnervation of muscles undergoing denervation because of peripheral nerve injury; and (2) their specificity in ensuring proximal motor and sensory axons are directed towards appropriate motor and sensory targets. Compared to conventional nerve grafting, nerve transfers offer opportunities to reinnervate muscles affected by cervical spinal cord injury and to augment natural reinnervation potential for very proximal injuries. This article provides a narrative review of the current scientific knowledge and clinical understanding of nerve transfers including peripheral nerve injury assessment and pre- and post-operative electrodiagnostic testing, adjuvant therapies, and post-operative rehabilitation for optimizing nerve transfer outcomes.

La présente étude est conduite dans u.n faciès particulier de In région : le terroir oilla,geois. 1. G. palpalis s.l. présente de fortes densités appa.ren,tes moyen.nes dans des biotopes péridontestiques (périph&ie du village, point d’ea,u). C’est la. seule espèce àpérzétrer a.11 centre du village. A l’opposé, G. pallicera présente des densités appa.rentes moyennes s’élec>a,nt à. mesu.re que les biotopes sont plus éloignés du village. Elle domine numériquement G. palpalis s.l. dans la, plantation de cacaoyers. G. nigrofusca a une distribu.tion proche de celle de G. pallicera avec des densités plus faibles. 2. La ua1eu.r du sez-ratio de G. palpalis s.l. est caractéristique des dijjîérents biotopes. Les mûles dominent les femelles da#ns les biotopes les plus om,bragés (forêt, point d’ea.u) et c’est l’inverse dans les biotopes les plus ensoleillés (périphérie du village). Dans les pla.ntation. s, de luminosité ambia.nte intermédia. ire, le sez-ra,tio est équilibré. L’occupation de b’espace pa,r les deux sexes de cette espèce est probablement détermin. ée essentiellement par des phototactismes différents. Ce n’est pa,s le cas de G. pallicera qui présente une distribution des mâles et des femelles très homogène da,ns tous les biotopes. 3. La densité a,ppa,rente de G. palpalis s.l. pou.r l’ensemble des biotopes péridomestiques (proches du village) ne présen. te que de faibles variations saison. nières. Il existe pur contre une redistribution. importante dans les différents biotopes en fowtion de leur éco-clim.at pa,rticulier : en saison sèche les femelles de G. palpalis s.l. trowent refu.ge da.ns les biotopes om bra,gès (planta.tion, foret et surtout point d’eau) et leur temps de présence à la, périphérie du village diminu,e. Dnns la pkntation de ca.caogers, su.ivent les conditions climatiques : les densités appa.ren. tes des trois espèces présentent des fluctuations qui croissance a.16 début et décroissance à la fin, de la saison des pluies. G. pallicera présente une brève ph.ase de dispersion, en fin de saison des pluies, comme I’a montré une augmentation de la. diversité des habitats fréquen,tés pa.r cette espèce para. llèlement à une dkcroissa.nce brrrta,le des densités appcrrentes. 4.

La périphérie du village est un. lieu de concentration pour les femelles ûgées, les biotopes ombragés, par contre, abritent les fractions les plus jeunes de la population (nullipa.res et jeunes pares).
Magnetotelluric Modelling and Inversion For Earthquake Studies in Taiwan

In this paper, we present a magnetotelluric (MT) modelling and inversion method for geophysical exploration using the Global Integral Local Differential (GILD) algorithm. We first describe GILD electromagnetic modelling and inversion algorithm and then apply it to interpret MT data from the Chi-Chi earthquake source area in Taiwan. In the resistivity image computed from the GILD algorithm, the Chelungpu (CLP) fault and the associated structures appear more clearly than those of the previous 1-D results.
