The Effect of Social Factors and Brand Image on The Decision of Parents in Choosing Education Services Educated by The Parent's Attitude

This study aims to examine and analyze the influence of social factors and brand image on decision making mediated by the attitude of parents of Al-Izzah Natural Elementary School, Sidoarjo Regency. The sampling technique is probability sampling and uses a saturated sampling method with a sample of 84 respondents. However, only 83 questionnaires can be processed using Partial Least Square. The results showed that social factors and brand image influence attitudes and decisions and attitudes also influence decisions. Looking at the mediating variables shows that attitudes give a partial mediating role to the influence of social factors and brand image on decisions. In further research, it is recommended to add new variables and the scope of the sample population to provide more complex and different results.
Personalized knowledge point recommendation system based on course knowledge graph

Existing class education lacks analysis of students’ learning data, which can not reasonably evaluate students’ mastery of knowledge points and locate students’ learning path in real time, nor effectively recommend the required knowledge points for students. In order to solve the above problems, a personalized knowledge point recommendation system model (KG-PKP) combined with the knowledge graph of the course is proposed. By using accuracy, answer-time and answer-types in answer records, evaluation equations which to judge students’ mastery of knowledge points can be constructed. We can extract the knowledge points in answer records and map them into the course knowledge graph. Personalized knowledge points for students can be recommended by using the semantic hierarchical relationship and sequence of knowledge points in the knowledge graph. The comparative experiment proves the validity and interpretability of the model.
Energetic proton depletion near Io: atmospheric charge exchange and inhomogeneous magnetic and electric fields

<p>The flux of energetic protons (80 keV-1.04 Mev) near the Galilean moons was measured by the Energetic Particle Detector (EPD) on the Galileo mission (1995 - 2003). Near Galilean moon, such as Io and Europa, depletions of the energetic proton flux, of several orders of magnitude, were observed. </p> <p>Such energetic proton depletions can be caused by the precipitation of these particles onto the moon's surface or charge exchange with the neutral atmosphere. In order to interpret the depletion features in the EPD data, a Monte Carlo particle tracing code has been developed by (H. L. F. Huybrighs et al., 2020; Hans L. F. Huybrighs et al., 2017; Hans Leo Frans Huybrighs, 2018). The expected flux of the energetic ions is simulated under different scenarios, for three Galileo flybys of Io (I24, I27, and I31), including with and without an atmosphere and inhomogeneous magnetic and electric fields. By comparing the simulated distribution to the EPD data, the cause of the depletion features can be investigated. </p> <p>The following causes of energetic proton depletion near Io are identified:</p> <ul> <li>Some depletions are consistent with atmospheric charge exchange for flybys I24, I27, and I31. </li> <li>Some of depletions coincide with the inhomogeneous fields produced in the MHD model by (Dols et al., 2012) for flybys I24, I27, and I31. </li> <li>For I24 the depletions are consistent with a two component atmosphere: a dense low scale height atmosphere and an extended corona described by a low surface density but a large scale height as presented by (Bl&#246;cker et al., 2018). </li> </ul> <p>Furthermore, latitudinal and longitudinal dependencies in the atmospheric models for Io are investigated for all three aforementioned flybys. </p> <p><strong>Bibliography</strong></p> <ul> <li>Bl&#246;cker, A. , Saur, J., Roth, L. , & Strobel, D.

Kinetics of Avermectin B1b Production by Streptomyces avermitilis 41445 UV 45(m)3 in Shake Flask Culture

Background: Use of avermectin B1b as anthelmintic and insecticidal agent has increased to protect soil and for enhanced crop production. Enhanced production of avermectin B1b was obtained from mutant strain of Streptomyces avermitilis 41445. Objectives: Modeling of mutant strain S. avermitilis 41445 UV 45(m) 3 growth and avermectin B1b production is therefore required for optimization during fermentation process. Kinetics of intracellular avermectin B1b production was studies in shake flask culture during submerged fermentation. Materials and Methods: Mathematical models based upon Logistic and Piret Equations have been used to investigate the kinetics of avermectin B1b production and substrate utilization from S. avermitilis 41445 UV 45(m)3. Effect of carbon sources (glucose, maltose, lactose, potato starch, soluble corn starch, and wheat starch), pH (6.0, 6.5, 7.0, and 7.5), agitation speed (150, 200, and 250 rpm) on microbial growth and product formation were evaluated. Results: Maximum avermectin B1b production (420.02mg.L-1 and cell biomass (31.74 g.L-1) were obtained in media having potato starch as carbon substrate at adjusted medium pH 7.5 and 250 rpm agitation speed. Maximum specific growth rate(µmax), growth associated avermectin B1b production coefficient (α) and non-growth associated avermectin B1b production coefficient (β) obtained were 0.16h-1, 0.0 mg.g-1 and 3.5 mg.g-1.h-1 respectively. Conclusion: From above results we can conclude that avermectin B1b production is non-growth associated process.
Low Power implementation of FIR Filter for De-noising the EOG signal

In this paper, we propose a modified FIR filter using canonical signed digit representation and compressor techniques for de-noising the Electrooculography signal (EOG). A dipole, formed between cornea and retina in an eye, resulting in voltage difference with occurrence of eye movement, which in turn generates an electrical signal. These electrical signals, called Electrooculography (EOG) signal and are useful in many medical and bioelectrical applications. To remove the noise in EOG signal an enhanced 16-bit FIR filter is used. The proposed FIR architecture uses canonical signed digit based multipliers and 3:2 or 4:2 compressors to achieve greater improvement in power and delay compared to conventional shift-add method of multiplication. Canonic signed digit (CSD) is used in order to reduce the design complexity of the multiplication by representing the filter coefficients in CSD format. Instead of using Carry Look Ahead adders, 4:2 compressors are used. The proposed approach is implemented on FPGA development kit.

Assessing the Quality of Swipe Interactions for Mobile Biometric Systems

Quality estimation is a key study in biometrics, allowing optimisation and improvement of existing authentication systems by giving a prediction on the model performance based on the goodness of the sample or the user. In this paper, we propose a quality metric for swipe gestures on mobile devices. We evaluate a quality score for subjects on enrollment and for swipe samples, we estimate three quality groups and explore the correlation between our quality score and a state-of-art biometric authentication classifier performance. A further analysis based on the combined effects of subject quality and the amount of enrollment samples is conducted, investigating if increasing or decreasing enrollment size affects the authentication performance for different quality groups. Results are shown for three different public datasets, highlighting how higher quality users score a lower equal error rate compared to medium and low quality users, while high quality samples get a higher similarity score from the classifier.
Analysis of Planar Multilink Cable Driven Robots Using Internal Routing Scheme

The multilink cable driven robot (MCDR) is an extension of the cable robots where the moving platform is replaced by a multibody chain. It is typically an open-chain structure with multiple links and complex cable routing. This design introduces the advantages of having a serial kinematic structure and preserves the benefits associated with cable-driven parallel mechanism. To achieve a minimum number of actuating cables while possessing a large workspace region, a novel internal cable routing scheme is proposed. It is shown that by incorporating internal routing with multi-segment cables, any serial chain with n degrees of freedom can be controlled with n + 1 cables. In this work, through studying the kinematics and statics, we demonstrate how internally-routed cable actuation of multilink manipulators have an increased workspace and reduced cable forces to execute trajectories.
Effect of nano‐polystyrene (nPS) on thermal, rheological, and mechanical properties of polypropylene (PP)

Polystyrene nanoparticles (nPS) in the range of 10–100 nm with spherical shape were synthesized by oil/water (o/w) microemulsion process. In this process ammonium persulfate (APS) as an initiator, sodium dodecyl sulphate as a surfactant and n-pentanol as cosurfactant were used. Isolated nPS was characterized by FTIR and 1H NMR spectroscopy. DSC studies of nPS showed higher Tg as compared to bulk PS. The effect of lower weight percentage (wt%) of nPS on the mechanical, rheological, and thermal properties of PP was investigated. The blends were prepared individually on brabender plastograph by incorporating nPS of ∼60 nm with different wt% of loading (i.e., 0.10–0.5%). It was shown from the experimental results that thermal, rheological, and mechanical properties were increased as the polymer particles blended with PP. Blends with 0.25 wt% loading of nPS exhibit better properties compared with that of other wt% loadings. The improvements in properties were due to the close packing of PP chains as recorded by improvement in crystallinity of PP with the addition of nPS as shown by SEM.

The Financial Literacy and Small and Medium Enterprises’ Performance in Lagos State, Nigeria: An Empirical Approach

The study examines the influence of financial literacy on the performance of SMEs with particular reference to SMEs registered with Lagos Business directory. The total population of the study comprises all 376 SMEs that registered and listed in Lagos Business Directory. Closed-ended questionnaires were employed to collect data from 190 SME entrepreneurs. The result reveals that the majority of the SME operators had a numeracy level of financial literacy of using a calculator for addition and subtraction only. This implies that most of the small business entrepreneurs did not have a spectrum of financial skills. It was also discovered that financial literacy dimensions independently and jointly influence SMEs’ performance. Therefore, the study recommends that SME entrepreneurs should leverage on the spectrum of financial skills, and also there should be a collaboration between SME entrepreneurs and accounting professional bodies in Nigeria, to organize seminars and workshops on financial literacy. Thus, this will go a long way to equip SME entrepreneurs with an array of financial skills such as book-keeping, cash management, inventory management, daily cash reconciliation and budgeting.
Detection of Anisotropy in Cartilage Using 2H Double-Quantum-Filtered NMR-Spectroscopy

Double-quantum-filtered (DQF) NMR spectroscopy of I = 1 spin systems is a diagnostic tool for the detection of anisotropy in macroscopically disordered systems. For deuterium, this method reveals the presence of a residual quadrupolar interaction for D2O in bovine nasal cartilage. This tissue is not macroscopically ordered and the quadrupolar splitting is not resolved. Fitting the calculated spectral lineshapes to the experimental results was possible only when a distribution of the residual quadrupolar interaction, omega(q), was assumed. The series of DQF lineshapes obtained for different creation times in the DQF experiment could be fitted using a single set of three parameters: the average residual quadrupolar interaction ωq/2π = 110 Hz, its standard deviation Δωq/2π = 73 Hz, and the transverse relaxation rate of 63 s−1. Separate deuterium DQF measurements for the constituents of the cartilage, collagen, and chondroitin sulfate indicated that the DQF spectra of cartilage are the result of anisotropic motion of D2O due to binding to the fibrous collagen in the tissue.
Digital Interventions for Depression and Anxiety in Older Adults: Protocol for a Systematic Review

Background There is a high prevalence of older adults experiencing depression and anxiety. In response to heightened demands for mental health interventions that are accessible and affordable, there has been a recent rise in the number of digital mental health interventions (DMHIs) that have been developed and incorporated into mental health treatments. Digital interventions are promising in their ability to provide researchers, medical practitioners, and patients with personalized tools for assessing behavior, consultation, treatment, and care that can be used remotely. Reviews and meta-analyses have shown the benefits of DMHIs for the treatment and prevention of depression, anxiety, and other mental illnesses, but there is still a lack of studies that focus on the benefits and use of DMHIs in the older population. Objective The aim of this systematic review is to investigate the current evidence for the effect of technology-delivered interventions, such as smartphone/tablet applications, remote monitoring and tracking devices, and wearable technology, for the treatment and prevention of depression and anxiety in adults older than 50 years. Methods The academic databases SCOPUS, PsycINFO, AgeLine (EBSCO), and Medline (PubMed) will be searched from January 1, 2010, to the date of search commencement to provide a review of existing randomized controlled trial studies. The search will include 3 key concepts: “older adults,” “digital intervention,” and “depression/anxiety. ” A set of inclusion criteria will be followed during screening by two reviewers. Data will be extracted to address aims and objectives of the review. The risk of bias for each study will be determined using appropriate tools. If possible, a random-effects meta-analysis will be performed, and the heterogeneity of effect sizes will be calculated. Results Preliminary searches were conducted in September 2020. The review is anticipated to be completed by April 2021. Conclusions The data accumulated in this systematic review will demonstrate the potential benefits of technology-delivered interventions for the treatment of depression and anxiety disorders in older adults. This review will also identify any gaps in current studies of aging and mental health interventions, thereby navigating a way to move forward and paving the path to more accessible and user-friendly digital health interventions for the diverse population of older adults.

Shear of Diblock Copolymer Lamellae: Width Changes and Undulational Instabilities

We investigate the effect of oscillatory shear on the lamellar spacing in melts of symmetric diblock copolymers in the strong segregation limit. We find that the equilibrium lamellar spacing decreases. The modulus due to entanglements plays an important role. We further argue that before equilibrium is reached the layers will show an undulational instability in the direction perpendicular to the velocity and the velocity gradient
Quantitative Determination of Sulfur Oxide Species in White Liquor by FT-IR

The Circle® cell has made possible the quantitative analysis of samples by infrared spectroscopy in aqueous solutions. With the use of this technique, which makes use of an FT-IR spectrometer, a novel analytical method is presented for the quantitative determination of sulfur oxide anions in white liquor. The method is appropriate only for oxidized sulfur species. However, it is shown that when Na2S concentrations are determined by another technique (e.g., ion chromatography or ion-selective electrode), the results can be used to carry out material/species balance on the unoxidized as well as oxidized samples of white liquor. The method is fast, straightforward, and convenient to use, and it does not require further treatments of white liquor solutions. Another advantage of this method is that it lends itself to in situ analysis. It is also general enough to be used for the quantitative analysis of other aqueous solutions. Linear regressions carried out on the SO=4, S20=3, and SO=3 species (in concentration ranges of 0–70, 0–45, and 0–42 g/L as salts, respectively) led to correlation coefficients of higher than 0.99; respective minimum detection limits of 0.01, 0.02, and 0.02 g/L were obtained. The latter can be further improved upon by employing longer-pathlength crystals. The method provides a way of carrying out material species balances, and studying reactions and their kinetics. The process does not use any toxic materials or environmentally unfriendly bleaching agents; it makes use of a combination of temperature, pressure, and molecular oxygen to oxidize white liquor to sulfate.
