Low Voltage Ride through Enhancement Using Grey Wolf Optimizer to Reduce Overshoot Current in the Grid-Connected PV System

In today’s world, the DG should not be disconnected in the event of a power outage but should instead remain linked to the grid and supported by reactive power. This can be accomplished by implementing the low voltage ride through (LVRT) with a proportional integral (PI) controller. As a result, the voltage profile can be enhanced. The PI controller, on the other hand, has drawbacks in that setting the gain takes a long time and results in an overshoot current on the grid, which could trigger the protection relay. To address this issue, this paper proposes employing a grey-wolf optimizer (GWO) to enhance the LVRT in a 5 MW three-phase grid-connected PV system. A MATLAB simulation was carried out then under a three-phase fault and load disturbance to verify the efficiency. It is found that, even with a 70% voltage sag, the PV system can remain connected to the electrical grid while minimising overshoot current on the grid side.
Linking teaching and research in an undergraduate course and exploring student learning experiences

ABSTRACT In this case study, we first describe how teaching and research are linked in a master’s course on tissue engineering. A central component of the course is an authentic research project that the students carry out in smaller groups and in collaboration with faculty. We then explore how the students experience learning in this kind of discovery-oriented environment. Data were collected through a survey, reflective writing, and interviews. Using a general inductive approach for qualitative analysis, we identified three themes related to the students’ learning experiences: learning to navigate the field, learning to do real research, and learning to work with others. Overall, the students strongly valued learning in a discovery-oriented environment and three aspects of the course contributed to much of its success: taking a holistic approach to linking teaching and research, engaging students in the whole inquiry process, and situating authentic problems in an authentic physical and social context.
Design and Fabrication of New Kind of Complex Ultrasonic Transducer

In order to improve the performance of ultrasonic transducer, a new kind of complex ultrasonic transducer was advanced. Two kinds of piezoelectric material are used in this transducer, in which PZT is used as transmitter and PVDF (Polyvinylidene Difluoride) is used as receiver. Using KLM (Krimholtz, Leedom and Mattaei) equivalent circuit model, this kind of transducer was analyzed theoretically. Based on the theoretical analysis and calculation, the complex ultrasonic transducer was designed and fabricated. The theoretical and experimental results show that this kind of transducer has low input power loss and relatively short pulse echo.
ESTIMATING A REGIONAL AIRPORT AIR PASSENGER DEMAND USING AN ARTIFICIAL NEURAL NETWORK APPROACH: THE CASE OF HUAHIN AIRPORT, THAILAND

: Artificial neural networks (ANNs) are a promising modelling approach for predicting an airport’s air passenger demand. The study proposed and empirically tested an artificial neural network model to predict the annual passenger demand for Huahin Airport, a regional and tourist focused airport located in Thailand. The ANN input variables included Thailand’s population size, Thailand’s real GDP, world jet fuel prices, Thailand total passengers carried, Thailand’s tourist numbers and Thailand’s unemployment rates. The data were trained using the Levenberg-Marquandt back-propagation algorithm. The ANN comprises eight neurons in the hidden layer and one neuron in the output layer. 80 per cent of the data was used in the training phase with the remaining data divided into validation (10 per cent) and testing (10 per cent) phases. The proposed ANN provided very accurate prediction values. The coefficient of determination R value of model was around 0.995, and the mean absolute percentage error (MAPE) of the final ANN model was 13.27%. The study found that the four key determinants of Huahin Airport annual air passenger demand were Thailand population size, the commencement of AirAsia services at Huahin Airport, Thailand’s tourist numbers, and Thailand’s real GDP.
The Surveillance of Physical Activity, Sedentary Behavior, and Sleep: Protocol for the Development and Feasibility Evaluation of a Novel Measurement System

Background There is increasing recognition of the need for more comprehensive surveillance data, including information on physical activity of all intensities, sedentary behavior, and sleep. However, meeting this need poses significant challenges for current surveillance systems, which are mainly reliant on self-report. Objective The primary objective of this project is to develop and evaluate the feasibility of a sensor-based system for use in the surveillance of physical activity, sedentary behavior, and sleep (SurPASS) at a national level in Denmark. Methods The SurPASS project involves an international, multidisciplinary team of researchers collaborating with an industrial partner. The SurPASS system consists of (1) a thigh-worn accelerometer with Bluetooth connectivity, (2) a smartphone app, (3) an integrated back end, facilitating the automated upload, analysis, storage, and provision of individualized feedback in a manner compliant with European Union regulations on data privacy, and (4) an administrator web interface (web application) to monitor progress. The system development and evaluation will be performed in 3 phases. These phases will include gathering user input and specifications (phase 1), the iterative development, evaluation, and refinement of the system (phase 2), and the feasibility evaluation (phase 3). Results The project started in September 2020 and completed phase 2 in February 2022. Phase 3 began in March 2022 and results will be made available in 2023. Conclusions If feasible, the SurPASS system could be a catalyst toward large-scale, sensor-based surveillance of physical activity, sedentary behavior, and sleep. It could also be adapted for cohort and interventional research, thus contributing to the generation of evidence for both interventions and public health policies and recommendations.

Disposable infrastructures: ‘Micromobility’ platforms and the political economy of transport disruption in Austin, Texas

The rapid rise of digital platform-based transportation services over the past decade has begun to transform urban mobility. Fleets of dockless bicycles and scooters – or ‘micromobility’– represent the newest horizon of investment, particularly in the United States. Micromobility platforms launch rapidly, with minimal public planning or funding and no fixed infrastructure, using inexpensive, GPS-connected vehicles stored in public space. These platforms represent a deepening of the neoliberalisation of transport, in which infrastructural properties emerge biopolitically from the dynamics of private platforms. This article examines public debates over the regulation of micromobility platforms in Austin, Texas, in early 2018. Drawing on interviews with city officials and bikesharing professionals, observation of public meetings and GIS analysis of usage data, we argue that conflicts we observed over new micromobility platforms – specifically ‘clutter’, equity in geographic coverage and data privacy – obscured the deeper political economy of platformisation and the austerity that limited the effectiveness of the existing public station-based bikeshare system. In Austin, the search for ‘innovative’ micromobility transportation at no public cost resulted in the further erosion of the underfunded public system. We argue that despite their flexible, low-carbon image, existing micromobility platforms in the United States largely exploit rather than address inadequacies of urban transport.
Low noise amplifier design with enhanced noise and gain performance using transformer boosting method for millimeter‐wave applications

In low noise amplifier (LNA) design, achieving minimum noise figure (NF) and enhanced gain is equally important in the field of communication. The major aim of this design with previous methods are those having implemented in the topology of design like metal oxide semiconductor field effect transistor at common source connection topology, pole‐based transformer boosting, and dual feedback technique. However, these methods fail to reach the desired performance due to their low NF and low gain. In order to overcome these failures and their causes, this article presented a topology in LNA design using a transformer as boosting component to improve the performance of NF and gain for millimeter‐wave applications. It has three common gate stages connected in cascode form, and three transformers are acquired to link the drain to the input signal. Transformers permit radio frequency feeding signal from drain to source, and output from the previous stage is connected to the input of the next stage. This connection increases the gain of the circuit and an enlarged coupling coefficient of value “1,” which minimizes noise. The unilateral coefficient remains to be 1, to make the circuit stable throughout execution. NF value can be minimized by properly selecting conductance coefficient and S‐parameter values. Since the transformer is used to provide feedback in this circuit, stability condition has to be analyzed carefully. Output load value is selected optimum as it creates an impact on the stability of LNA. This topology implemented in LNA design helps to increase the gain by boosting the signal input, and hence, in turn, it increases overall gain performance. Similarly, while executing this optimal LNA design using transformer boosting technique in CADENCE software, this LNA exhibits a minimum NF of 3 dB at 30 GHz and power gain of 12.2 dB at 50 GHz in measurement. Comparatively, the proposed LNA design overruns conventional methods and consumes a power supply of 1.1 V.
A High-Fat Diet Induces Low-Grade Cochlear Inflammation in CD-1 Mice

There is growing evidence for a relationship between gut dysbiosis and hearing loss. Inflammatory bowel disease, diet-induced obesity (DIO), and type 2 diabetes have all been linked to hearing loss. Here, we investigated the effect of a chronic high-fat diet (HFD) on the development of inner ear inflammation using a rodent model. Three-week-old CD-1 (Swiss) mice were fed an HFD or a control diet for ten weeks. After ten weeks, mouse cochleae were harvested, and markers of cochlear inflammation were assessed at the protein level using immunohistochemistry and at the gene expression level using quantitative real-time RT-PCR. We identified increased immunoexpression of pro-inflammatory biomarkers in animals on an HFD, including intracellular adhesion molecule 1 (ICAM1), interleukin 6 receptor α (IL6Rα), and toll-like-receptor 2 (TLR2). In addition, increased numbers of ionized calcium-binding adapter molecule 1 (Iba1) positive macrophages were found in the cochlear lateral wall in mice on an HFD. In contrast, gene expression levels of inflammatory markers were not affected by an HFD. The recruitment of macrophages to the cochlea and increased immunoexpression of inflammatory markers in mice fed an HFD provide direct evidence for the association between HFD and cochlear inflammation.
Polska adaptacja skali wartości materialnych (MVS) – właściwości psychometryczne wersji pełnej i wersji skróconych

The Material Values Scale (MVS) developed by Richins and Dawson (1992) is the most frequently used worldwide measurement of materialism. Although it has also been used in Polish research for almost a quarter of a century, the measurement properties of its Polish adaptations have not been systematically examined thus far. This article fills the gap. It contains an analysis of the measurement properties of the Polish adaptation (MVS_PL), which was based on three raw data sets. The author examined the basic 15-item MVS and three short versions consisting respectively of nine, six, and three items. The results show that all versions of MVS_PL have at least acceptable psychometric properties, but the scales with nine and six items best fit the Polish data. The analysis confirms that MVS_PL is a good, reliable, and accurate tool that could be recommended to measure materialistic orientation in the Polish environment.
A Survey of Physical Fatigue during Use of a Tablet LCD Monitor

This paper describes an investigation of the fatigue awareness of different parts of the body and operational performance when using a tablet LCD monitor tilted at various angles. The results showed that the shoulder, wrist, forearm, and upper arm experienced the most fatigue while the elbow experienced the least. The fatigue awareness of the neck, back, and waist had the highest levels when the tablet LCD monitor was placed horizontally. An angle of 25° from the horizontal was the most comfortable for users and was the angle that users were most willing to use in the future. Gender had no obvious effect on fatigue level, comfort level, future willingness to use, and operational performance. However, the tilt angle of the monitor had a significant effect on fatigue level, comfort level and future willingness to use, but had no significant effect on operational performance.
Compact single/dual band BPF with harmonic suppression using open-loop resonator and L-shaped coupling arm

: A new approach is presented to design a widestopband single and dual-band bandpass filter (BPF) using L-shaped coupling-arm and open-loop resonators (OLRs). Non-uniform gap between the L-shaped coupling-arm and OLR and the length of the coupling-arm lead to the selective and collective suppression of higher order harmonics. Using voltage wave analysis, it is shown that the coupling-coefficient reduces to zero for certain harmonics. To demonstrate the application of the proposed technique single and dual-band BPFs is designed and fabricated. Second- and fourth-order single-band BPFs are fabricated for the centre frequency of 2.24 GHz. Harmonic suppression up to 5.8 f o with the suppression level >30 dB is achieved in second-order BPF. One more second-order BPF is designed and fabricated using stub-loaded stepped impedance OLR. This BPF displays widestopband up to 8.4 f o with the suppression level of 30 dB. Further a compact dual-band BPF is also designed and fabricated. The response shows the harmonic suppression up to 5.3 f o . The measured results are in good agreement with the full-wave simulation performed by high-frequency structure simulator.
HARPAGON: An Energy Management Framework for Attacks in IoT Networks

The Internet of Things (IoT) represents an eclectic paradigm that is still growing in popularity. However, security aspects are a major concern for IoT devices due to their applications and the amount of sensitive data they provide. Simultaneously, the energy constraint in IoT networks remains a significant issue due to their limited resources. To reduce their energy consumption, several IoT protocols have integrated the energy-saving mode which offers four operating modes. On the basis of these four states, we derive an analysis framework, named HARPAGON, allowing an attacker to maximize his attack efficiency and minimize his impact in terms of energy consumption. Indeed, the effectiveness of many attacks depends principally on the state of the attacker and the victim at the same time. HARPAGON with the help of Markov chain theory allows modeling the interaction between the attacker and its victims. In this article, we demonstrate the effectiveness of the framework coupled with a jamming attack by comparing it to other types of jamming attacks. Experimental results reveal HARPAGON combined with a jamming attack drastically reduces the performance of the network, with an impact on the packet error rate (PER), which is around 13% higher than the reactive attack and with a reduced energy budget in respect of the other two well-known “green” jamming attacks.
Sorghum Crop Modeling and Its Utility in Agronomy and Breeding

Crop models are simplified mathematical representations of the interacting biological and environmental components of the dynamic soil–plant–environment system. Sorghum crop modeling has evolved in parallel with crop modeling capability in general, since its origins in the 1960s and 1970s. Here we briefly review the trajectory in sorghum crop modeling leading to the development of advanced models. We then (i) overview the structure and function of the sorghum model in the Agricultural Production System sIMulator (APSIM) to exemplify advanced modeling concepts that suit both agronomic and breeding applications, (ii) review an example of use of sorghum modeling in supporting agronomic management decisions, (iii) review an example of the use of sorghum modeling in plant breeding, and (iv) consider implications for future roles of sorghum crop modeling. Modeling and simulation provide an avenue to explore consequences of crop management decision options in situations confronted with risks associated with seasonal climate uncertainties. Here we consider the possibility of manipulating planting configuration and density in sorghum as a means to manipulate the productivity–risk trade-off. A simulation analysis of decision options is presented and avenues for its use with decision-makers discussed. Modeling and simulation also provide opportunities to improve breeding efficiency by either dissecting complex traits to more amenable targets for genetics and breeding, or by trait evaluation via phenotypic prediction in target production regions to help prioritize effort and assess breeding strategies. Here we consider studies on the stay-green trait in sorghum, which confers yield advantage in water-limited situations, to exemplify both aspects. The possible future roles of sorghum modeling in agronomy and breeding are discussed as are opportunities related to their synergistic interaction. The potential to add significant value to the revolution in plant breeding associated with genomic technologies is identified as the new modeling frontier.

Autogenic Signals in the Sedimentary Record of Organic Carbon Preservation

The burial of organic carbon (OC) preserves paleoenvironmental archives and drives the evolution of Earth's biogeochemical cycles. While the impact of kinetic heterogeneity on OC preservation has been studied, the effects of sedimentation dynamics remain largely unknown. Here, we incorporate the expected stochastic variability in sedimentation rates into a reactive‐transport model, generate predictions for stratigraphic variability of OC burial efficiency, and compare the model outputs to field observations. We find that internal sedimentation dynamics profoundly influence OC preservation efficiencies and create autogenic signals that may obscure signals originated from external forcings. Simulations match observations in terms of power spectra when our model considers transient periods of erosion during net deposition, implying that the manifestation of sedimentation dynamics and their interactions with biogeochemistry in chemostratigraphic records are prevalent in nature. As sedimentary OC records reflect both internal variability and external forcing, they may be used as proxies for past depositional conditions.
DEVELOPMENT OF A CROSS-CULTURAL COMPETENCY SCALE BASED ON THE EXPERIENTIAL MODEL OF CROSS-CULTURAL LEARNING SKILLS

"The aim of this study was to develop a cross-cultural competency scale based on perspectives from the experiential model of cross-cultural learning skills for successful adaptation of international assignees. The study involved 134 participants from 41 countries who studied at a graduate school in Japan, specializing in international relations and international management. Maximum likelihood exploratory factor analysis was conducted with varimax rotation, extracting three latent components of cross-cultural competency: building relationships, translation of complex information, and conflict management. To validate those components, confirmatory factor analysis was conducted with the same group of participants. Results showed acceptable levels of model fit, and the reliability of the three components ranged from 0.83 to 0.87. Accordingly, the cross-cultural competency scale developed in this study seems to be an effective measurement model to analyze cross-cultural competencies. "
Education-Centred Formal Wraparound Services in Support of School-Aged Students With Complex Support Needs: A Systematic Review

Abstract The aim of this systematic review was to map the peer-reviewed literature (2009–2019) relating to school involvement with wraparound models in the support of students with complex needs. Specific research questions addressed explored the evidence base of the efficacy of wraparound with these students and barriers and enablers in the provision of wraparound services. Database searches were conducted and a total of 50 articles were identified. The analysis revealed eight different aspects of wraparound efficacy, with mixed results. Nine factors were identified as having a positive enabling, or disabling, effect on the provision of effective wraparound services. The wraparound programs were varied in their nature and in their successful implementation, with time to allow the program to mature and adherence to the 10 principles of the wraparound process emerging as enabling factors for wraparound success.
Genetic causal beliefs and developmental context: Parents’ beliefs predict psychologically controlling approaches to parenting

We examined the association of parents’ genetic causal beliefs and parenting behaviors, hypothesizing a positive association between parents’ genetic causal beliefs and their use of psychological control. Study 1 (N = 394) was a cross-sectional survey and revealed that parents’ genetic essentialism beliefs were positively associated with their self-reported use of harsh psychological control, but only for parents who reported relatively high levels of problem behaviors in their children. Study 2 (N = 293) employed a 4-day longitudinal design and revealed that parents’ genetic causal beliefs positively predicted the use of psychological control, especially on days when they perceived relatively high problem behaviors in children. Overall, the studies demonstrated that parents’ genetic causal beliefs about character positively predicted psychologically controlling and harsh responses to child problem behaviors, which may ultimately be detrimental to child development.
