Control Performance of Two-stage Positioning System with Intelligent Control Methods.

As a high precision positioning system with a long working range and high speed, two-stage positioning systems which include the coarse and the fine positioning mechanisms have been proposed. However their most suitable control method has been clarified yet. The purpose of this research is to clarify the most suitable control method for the systems theoretically and experimentally. For this purpose, this paper discusses the performances of the positioning systems with two kinds of intelligent control methods such as the neural control and the fuzzy control ones. Each controller comprises two sub-controllers ; one is for the coarse positioning mechanism and the other is for the fine one. Both controllers are designed by using the dynamic reference models of the mechanism which is expressed on phase plane. Effect of step height, the table mass and constant load changes on the positioning performances are evaluated by simulation and experiment.
Reducing Obesogenic Eating Behaviors in Hispanic Children through a Family-Based, Culturally-Tailored RCT: Abriendo Caminos

Family-based interventions that incorporate culturally-tailored multi-component curricula and are grounded on evidence-based information and theoretical frameworks can help reduce the prevalence of obesity among Hispanic children. Abriendo Caminos: Clearing the Path to Hispanic Health is a multi-site culturally-tailored randomized control trial that aims to reduce obesity rates in Hispanic families by delivering education on nutrition, family wellness, and physical activity. This study evaluated the effect of the Abriendo Caminos six-week intervention on dietary behaviors of Hispanic children (6–18 years). Mothers (n = 365) reported their child’s eating behavior intake using the U.S. Department of Education’s Early Childhood Longitudinal Study protocol (ECLS). Pre/post dietary changes were evaluated using separate generalized estimating equation models adjusted for site, child sex, and child age group. Findings indicate a reduction in the frequency of sugar-sweetened beverages (OR 0.55, 95% CI 0.35, 0.87, p = 0.01), French fries (OR 0.56, 95% CI 0.36, 0.86, p = 0.009), and fast food (OR 0.55, 95% CI 0.36, 0.84, p = 0.006) consumption among children in the intervention arm. Additionally, children in the intervention arm increased their frequency of vegetable consumption (OR 1.84, 95% CI 1.08, 3.12, p = 0.03). The Abriendo Caminos intervention effectively improved four of eight eating behaviors in a short-term intervention.
RESEARCH IN AUTOMATIC MILKING SYSTEM CAPACITY

The aim of the research is to state the capacity of automatic milking systems (AMS) in operation conditions and to determine the maximal size of the cow group that could be served by one AMS. The research was performed on three different farms. On every farm the cows are milked by two company "DeLaval" produced AMS. The main initial data are obtained processing the information in the farm management systems. A corresponding algorithm has been developed for calculating the AMS operation time, capacity and maximal size of the herd. The research results show that the AMS capacity is influenced by different factors: the size of the served group of cows, time spent in the milking stand, time for servicing of milking machines and milk tanks, kind of cow traffic to milking, design of the milking zone etc. Using the company "DeLaval" produced AMS the maximal size of the herd served by one AMS should not exceed 58 - 59 cows.
Uncertainty Quantification via Variable Fidelity Kriging Model

In this paper, a variable fidelity Kriging model approach is applied to aerodynamic data modeling and uncertainty quantification of 2D airfoil aerodynamic performances. This approach enables to construct an accurate surrogate model efficiently by utilizing high and low fidelity function information simultaneously. The low fidelity functions are defined by utilizing coarser computational meshes in this research. The uncertainty quantification is executed by Monte-Carlo simulation on the surrogate model, which is often referred to as Inexpensive Monte-Carlo simulation approach. The developed uncertainty quantification approach showed comparable accuracy with full non-linear Monte-Carlo simulation results and was executed with much lower computational cost.
Impact of radiation and heat generation/absorption in a Walters’ B fluid through a porous medium with thermal and thermo diffusion in the presence of chemical reaction

ABSTRACT In this paper, the analytical technique is adopted to investigate the behaviours of the various patients in the non-Newtonian type model of a Walters’ B fluid through a porous medium with the interactive impact of thermal radiation, heat generation/absorption and diffusion thermo impact in the presence of thermal diffusion and chemical reaction. The highly nonlinear systems of equations responsible for the behaviours of the model are modified to the system of coupled nonlinear ordinary differential equations via the fluid variables. The converted equations are executed by Homotopy Analysis Method (HAM). The significance of magnetic parameter, local Weissenberg number as well as other parameters encountered are discussed accordingly. Among the major finding is the variation in thermal buoyancy parameter, which accelerates the motion of the fluid and cools the problem with a significant role of cooling of the system and other electronic panels in the science-related field while the quiescent-fluid gained thermal-effect on the account of the penetration of strong convective-heating for different values of convective-heat parameter which contributes to the drying of material components in technological-related disciplines.
Compact RF planar filters-improvement of the out-of-band rejection and tunabiliity

The purpose of this work was to develop RF bandpass filters in PCB technology,with three main objectives. The first objective was to develop synthesis formulas tosimplify the design procedure of the filter. The second was to achieve wideout-of-band rejection without modifying the in-band filtering characteristics. Thethird objective was to control the center frequency of the filter by using varactordiode.The bandpass filter topology treated in this thesis is based on Stub-LoadedResonators (SLR). The main features of this filter topology were treated. Equivalentcircuits based on J-inverters and susceptance parameters were derived. Based onthese equivalent circuits, synthesis formulas were developed. Simulations werepresented to validate the synthesis theory. For a proof-of-concept, third orderstripline bandpass filters were designed and fabricated based on this synthesis.Analysis technique using odd- and even- mode was achieved on the SLR. Thusresonance odd- and even-mode conditions were derived. These conditions aim toeasily control the first spurious frequency. Moreover, to go further in improving theout-of-band rejection a new technique, called “U corner structure”, was developedand design rules were derived. Based on these design rules an extended out-of-bandrejection was achieved without any modification in the passband and by maintainingthe compactness of the filter. A first spurious frequency was localized at up to ninetimes the working frequency in the case of the Parallel-coupled Stub-Loadedresonator (PC-SLR) filter. Also, by applying this technique into the classicalparallel-coupled filter the first and second spurious frequencies were rejected. Toaddress the issue of tunable filters, the SLRs were correctly loaded by variablecapacitors (varactor diode). The center frequency of the PC-SLR filter was easilycontrolled by maintaining a large out-of-band rejection.
Storm time polar cap expansion: IMF clock angle dependence

Abstract. It is well known that the polar cap, delineated by the Open Closed field line Boundary (OCB), responds to changes in the Interplanetary Magnetic Field (IMF). In general, the boundary moves equatorward when the IMF turns southward and contracts poleward when the IMF turns northward. However, observations of the OCB are spotty and limited in local time, making more detailed studies of its IMF dependence difficult. Here, we simulate five solar storm periods with the coupled model consisting of the Open Geospace General Circulation model (OpenGGCM) coupled with Coupled Thermosphere Ionosphere Model (CTIM) and the Rice Convection Model (RCM), i.e., the OpenGGCM-CTIM-RCM model, to estimate the location and dynamics of the OCB. For these events, polar cap boundary location observations are also obtained from Defense-Meteorological Satellite Program (DMSP) precipitation spectrograms and compared with the model output. There is a large scatter in the DMSP observations and in the model output. However, we generally find good agreement between the model and the observations. On average, the model overestimates the latitude of the open-closed field line boundary by 1.61 degrees. Additional analysis of the simulated polar cap boundary dynamics across all local times shows that the MLT of the largest polar cap expansion closely correlates with the IMF clock angle; that the strongest correlation occurs when the IMF is southward; that during strong southward IMF the polar cap shifts sunward; and that the polar cap rapidly contracts at all local times when the IMF turns northward.
Examining the Ability of Two Actigraph Models to Detect and Discriminate Between Low Frequency Movements

Recently, there has been a notable shift to increasingly more sedentary lifestyles, yet it remains unclear whether inexpensive accelerometers, such as those contained in Actigraph devices, can provide consistent measurements of low magnitude accelerations. This study sought to explore the ability of two Actigraph models to differentiate low frequency oscillations, in reference to higher-end accelerometers with the idle sleep mode disabled (ISM) (Part 1) and enabled (Part 2) in a controlled environment. Eight GT9X, fifteen wGT3X-BT and two higher-end accelerometers (Triaxial ICP) were mounted to a 6-degree of freedom robot, which introduced frequencies ranging from 0.5-2.0 Hz (Part 1) and 0.5-4.0 Hz (Part 2). To compare the models, the minimum, maximum and range of outputs were calculated for each of the frequencies. Part 1 revealed that the Actigraph monitors were able to detect low frequency oscillations; the captured output was similar across the different Actigraph models but was significantly greater than the higher-end devices. Part 2 demonstrated that amplitudes greater than the described 40 m g (0.392 m/s2) threshold were required for the Actigraph monitors to wake up. This study demonstrates that the GT9X and wGT3X-BT Actigraph accelerometers can detect low magnitude movements when the ISM is disabled.
Optimization of Deep Eutectic Solvent Extraction of Phenolic Acids and Tannins from Alchemilla vulgaris L.

Alchemilla vulgaris L. is a good source of antioxidant components with an emphasis on phenolic acids and tannins. In this study, gallic acid, ellagic acid, and hydrolyzable tannins (HT) were extracted from this plant with different deep eutectic solvents (DESs), varying the amount of added H2O, temperature and extraction time. Seventeen DESs (n = 3) were used for the extraction, of which choline chloride:urea (1:2) proved to be the most suitable. The selection of the best solvent was followed by the examination of the influence of the extraction type and parameters using response surface methodology (RSM). Gallic acid content was in the range of 0.00–1.89 µg mg−1, ellagic acid content was 0.00–12.76 µg mg−1 and hydrolyzable tannin (HT) content was 3.06–181.26 µgTAE mg−1, depending on the used technique and the extraction conditions. According to the results, extraction by stirring and heating was the most suitable since the highest amounts of gallic acid, ellagic acid, and HT were extracted, and the obtained optimal values using response surface methodology (RSM) are confirmed by experimentally obtained values.
Impact of Gleason score of the tumor at the positive surgical margin as a prognostic factor

Although numerous studies have reported that a positive surgical margin (PSM) is the most important predictive factor for biochemical recurrence (BCR) of prostate cancer (PCa), only a small number of studies have evaluated the predictive value of the Gleason score (GS) of the tumor at the margin in radical prostatectomy (RP). The present study aimed to investigate the preoperative factors that predict PSM and the significant predictive factors for BCR in cases with PSM. In addition, it was examined whether documenting the GS of the tumor at the margin in pathological reports is useful as a predictive factor for BCR. Data of 241 patients with PCa who underwent RP at Kurume University Hospital (Kurume, Japan) between January 2007 and December 2011 were retrospectively reviewed. The median follow-up period was 72 months and 122 patients had at least one PSM. The time to BCR was significantly shorter in patients with PSM than in those with a negative surgical margin. Multivariate analysis demonstrated that >10 ng/ml prostate-specific antigen at diagnosis (P=0.024) and >25% positive core at biopsy (P=0.041) were independent prognostic preoperative factors for PSM. The GS of the tumor at the margin was equal, lower and higher than those of the main tumor in 74 (60.7%), 16 (13.1%) and 32 (26.2%) RPs, respectively. The BCR rates were 35.7, 55.1 and 82.1% in patients whose GS of the tumor at the margin was 6, 7 and 8-10, respectively (P=0.0017). The GS of the tumor at the PSM (P=0.038) and anatomic location of the PSM (P=0.04) were identified as independent prognostic preoperative factors for BCR, whereas the GS of the main tumor and margin length were not. These results suggest that documenting the GS at the margin in pathological reports is useful as a predictive factor for BCR.
Adaptive Priority Adjustment Scheduling Approach With Response-Time Analysis in Time-Sensitive Networks

With the advent of Industry 4.0 and the popularization of smart terminal equipment, the interaction between industrial field information systems and production equipment has intensified. To meet the real-time transmission of time-triggered flow and the coordinated transmission of best effort flow, time-sensitive network-related technologies are used to implement flow queue forwarding by strictly following the gate control list. First, response-time analysis method is proposed to predict the upper bound of delay under a scheduling model following IEEE 802.1Qbv. Second, according to response-time analysis, a deadline monotonic scheduling algorithm with temporary priority expansion is proposed to divide the priority into more levels, which is not limited by the queue type, so as to ameliorate the transmission sequence of switch export flow. Finally, an adaptive priority adjustment scheduling algorithm with temporary priority expansion is designed to construct the optimal scheduling method further improving the scheduling success rate and reducing worst-case end-to-end delays. Compared with similar algorithms, the algorithm proposed improves the scheduling success rate by at least 30%, reduces the total delay by at least 21% and the TT flow delay by 11% in high network utilization conditions.
Body morphometric and otolith shape analyses of anchovy (Engraulis encrasicolus (Linnaeus, 1758)) in the Algerian basin

Body morphometric characteristics and otolith shape described by elliptic Fourier descriptors analyses were carried out on European anchovy (Engraulis encrasicolus) samples collected from six locations in Algerian waters during the acoustic survey ALPEL2018 (south-western Mediterranean Sea, GFCM-GSA04). The discriminant analysis was applied over twelve morphometric body distances and 31 normalized elliptic Fourier descriptors. It highlighted significant difference between areas but with high overlapping. No significant difference was detected between males and females, or right and left otoliths. Hierarchical clustering analysis conducted on the mean form of body and otolith shape showed a clear geographical cline. The results indicate that the geographical trend is present with a high level of overlapping between the near areas, suggesting that European anchovies in Algerian waters are not completely isolated.
Ship Air Wake CFD Comparisons to Wind Tunnel and YP Ship Results

As part of a project to determine ship air wake impact on naval rotary wing vehicles, this paper compares wind tunnel and computational fluid dynamics (CFD) simulations with in situ data that has been collected on an instrumented United States Naval Academy (USNA) YP (Patrol Craft, Training). The in situ data has been collected underway on a vessel which is 108 ft long and has a 24 ft above water line height. The wind tunnel data is from a 4% scale model tested in the USNA 42 × 60 × 120 inch wind tunnel. CFD simulations were performed on a 15.5 million tetrahedral unstructured grid. Data from the three sources is compared over 11 vertical and horizontal planes above the flight deck on the stern section of the YP. Data is compared for a head wind condition and for relative wind 15° off the starboard bow. Good comparison in velocity direction, typically less than 10-15°, is observed in the vertical and horizontal planes. Normalized velocity magnitudes do not compare as well, likely arising from the lack of an atmospheric boundary layer modeled in CFD simulations and wind tunnel testing.
Staphylococcus aureus nt5 gene contributes to bacterial infection ability to form kidney abscess

Staphylococcus aureus (S. aureus) is a commonly conditional infection pathogen, in which several key virulence genes are responsible for bacterial infection ability. The S. aureus nt5 gene, encoding 5’-nucleotidase, mediates bacterial nucleic acid pathway, yet it is nearly unknown of nt5 function for staphylococcal infection ability. Herein we have constructed S. aureus mutant with the gene nt5C166T silence (S. aureus Δnt5) by a CRISPR RNA-guided base editing system to investigate bacterial infection ability in vitro and in vivo. As expected, several nt5-related genes are disturbed in S. aureus Δnt5, in which gene transcription level of py is decreased compared with the wild-type S. aureus. Bacterial gene nt5 is downregulated and py/adk are upregulated when S. aureus is exposed to antibiotics daptomycin, which indicates nt5-mediated nucleic acid pathway is interfered upon with daptomycin treatment. Furthermore, the mutant Δnt5 displays about a 40-fold reduction of bacterial loading in mouse kidney on a mouse sepsis model, and the infection ability of Δnt5 is reduced than the wild-type bacteria. The gene nt5 contributes to S. aureus-infected abscess formation in mouse kidney, and the silence of nt5 gene promotes phagocytosis of S. aureus by mouse and human immunocytes. In general, our findings reveal nt5 silence impedes bacterial loading in kidney to form abscess but enhances S. aureus to be phagocytosed by host cell immune system in vitro and in vivo, which indicates that nt5 gene plays an important role in bacterial infection and immune evasion.
Impact of Technology Readiness and Techno Stress on Teacher Engagement in Higher Secondary Schools

Rapid technology advancements resulted a fundamental shift in the education sector which redefined the teaching-learning process and teacher engagement. Based on numerous studies on work engagement models and technology readiness, this study explores, how the teachers’ readiness to embrace educational technologies, impact on teacher engagement. With stratified cluster sampling model, data were collected from principals, managers, students and 122 faulty were participated in this quantitative study using standardized tools. Teachers were highly engaged with students-colleagues and varied across experience/age groups. Technology readiness factors positively impacted on social engagements with students-colleagues. As education technology usage is exponential, more future research is needed.
A High Efficiency and High Power Density DC Transformer Topology With Output Regulation Capability

LLC based dc transformer (DCX) with fixed voltage ratio is a suitable candidate for telecommunication equipment and data center for its high efficiency. Traditionally, a pulsewidth modulation (PWM) regulator are employed to achieve voltage regulation capability. However, the two-stage structure makes sacrifice in efficiency. Hence, this article proposes a novel partial regulated DCX with fixed switching frequency. The input power issplit into two parts in the proposed converter. Most power is delivered by the main DCX and only a small part is converted by an auxiliary DCX cascading with a PWM converter. The output voltage of DCX can be regulated by the PWM converter. Therefore, the efficiency sacrifice is minimized and high efficiency can be obtained. The operating principle and design consideration are analyzed to achieve an optimal global efficiency. The source-impedance-equivalent method is also proposed to simplify the small-signal modeling process. Based on the proposed topology, a prototype with 360–440V input and 12V/500-W output is demonstrated. A peak efficiency of 96.3% and a power density of 148 W/in3 are achieved on the prototype. A total 2% efficiency improvement and 55% power density improvement can be obtained compared with the conventional two-stage structure.
