Acoustic energy harvesting using phononic crystal fiber with conical input

In this paper, a novel phononic crystal fiber with conical input is introduced for coupling environmental acoustic waves to the fiber core. Environmental acoustic waves can be focused and coupled to the core through conical input. In the first step, a cone shape coupler has been considered for coupling the incident acoustic waves to the core region. This initial idea has a significant acoustic energy loss. This disadvantage encourages us to design a new phononic crystal fiber without it. Designed structure includes a phononic crystal fiber with conical input meaning solid rods have been shaped in conical way at the input section of fiber. By using this structure, environmental acoustic waves can be properly coupled to the core region of the fiber. Acoustic wave leakage to outside of the Phononic crystal fiber has been extremely decreased in comparison with initial coupler. Experimental results indicate that environmental acoustic waves can be focused and coupled to the core region by phononic crystal fiber with conical input.

Features of fluoroethers-filled flat plate pulsating heat pipe: Influence of cooling temperature and semi-empirical modeling

We studied the effects of heat input and cooling temperature on the operational characteristics and heat transfer characteristics of flat plate pulsating heat pipes (FPPHP) using HFE-7100, HFE-7200 and HFE-7300 as working fluids. Empirical correlation equations were fitted to predict the thermal performance of FPPHP. The results showed that the start-up heat input, ultimate heat input, thermal resistance, and evaporation section temperature were positively correlated with boiling point under most operating conditions. At a cooling temperature of 20℃, the FPPHP start-up heat inputs for HFE-7100, HFE-7200, and HFE-7300 are 50 W, 70 W, and 110 W, respectively. After the start-up of the FPPHP, with the increase of cooling temperature, the flow patterns of slug flow, churn flow, annual flow, and vapor region appear successively. FPPHP has lower thermal resistance and ultimate heat input at higher cooling temperatures. At a cooling temperature of 80℃, the ultimate heat inputs of the three fluoroethers in FPPHP are 50 W, 50 W, and 90 W, respectively. In addition, it fills the gap in the empirical equations related to FPPHP and fluoroether working solutions and expands the Ku value range in the current experimental equations to 0.084.

Стационарное протекание несжимаемой вязкой жидкости сквозь двухмерный разветвленный канал

The results of a numerical experiment for the problem of an incompressible viscous fluid stationary flow through a branched planar (two-dimensional) channel are presented. The region in which the flow occurs simulates either blood vessels or a river delta. The finite element method and a modification of the penalty method, as well as the splitting method, are used for calculations. The implementation of the calculation algorithm is using with the help the package FreeFem++. The main goal, in addition, of course, to study the properties and structure of the stationary flow, is to demonstrate the effectiveness of the proposed modification of the penalty method. It is assumed that the region has one input boundary section through which the liquid flows into the region, and several (five) boundary sections through which the liquid flows out of the region. The remaining sections of the region boundary are considered impermeable to liquid. The boundary condition corresponding to the Poiseuille flow in a plane rectilinear channel is set at the input section. Three types of boundary conditions are considered on the output boundary secctions. 1. The boundary conditions correspond to the conditions of conservation of motion of luid particles i. e. the material derivative of the velocity is zero. 2. The boundary conditions correspond to the setting of the flow velocity. 3. The boundary conditions correspond to the setting of the same pressure. The stationary solution is constructed by the relaxation method. In fact, a non-stationary problem is solved over a sufficiently large time interval. As an initial condition for a non-stationary problem, a flow is chosen that is a Poiseuille flow in some region near the input boundary. The dependence of the convergence rate of the relaxation method on the initial data is investigated. It is found that the Poiseuille flow, given at the input section of the boundary of the region, induces similar Poiseuille flows at the output boundaries sections of the region in all these cases of boundary conditions. For a region with five sections of the output boundaries for some configuration of the region, the presence of stationary vortex flows (‘maelstorm’) is found.

In the electronics system section, the input section uses the HC SR04 sensor, the processing system uses an integrated Arduino Uno board system and an RTC DS3231 timer system, for the output itself to be displayed in the form of an LCD (liquid crystal display) and stored in the Secure Digital Card module in the form of a data logger. It is hoped that with this P2SOP instrument in the future tide measurements can be carried out in an automated manner and minimize the occurrence of inaccurate measurement times and reading errors on manual tide measurements.

Factors causing emergency medical care overload during heatwaves: A Delphi study.

Heatwaves pose an important risk for population health and are associated with an increased demand for emergency care. To find factors causing such overload, an online Delphi study included 15 experts in emergency medicine, disaster medicine, or public health. One open-ended question was delivered in the first round. After content analysis, the obtained statements were sent to the experts in two rounds to be rated on a 7-point linear scale. Consensus was defined as a standard deviation ≤ 1.0. Thirty-one statements were obtained after content analysis. The experts agreed on 18 statements, mostly focusing on the input section of patient processing and identifying stakeholders, the population, and primary care as targets of potential interventions. Additional dedicated resources and bed capacity were deemed important as per throughput and output sections, respectively. These findings could be used in the future to implement and test solutions to increase emergency healthcare resilience during heatwaves and reduce disaster risk due to climatic change.

AUTOMATIC PLANT WATERING PROTOTYPE AND RAT REPELLENT ON EGGPLANT

Water is the main constituent of plant cells. Eggplant plants include plants that are not drought tolerant, but also not resistant to standing water. In addition, eggplant is also susceptible to rat pests. Most farmers in Indonesia still use the manual method, sometimes when using the manual method it can lead to negligence in watering plants and guarding against rat pests. The use of mechanization tools is needed to facilitate and overcome negligence that can occur at any time, which can help plant cultivation by getting the best results, overcoming negligence that can cause losses, and damage to plants. In this tool there are several components of input, process, and output. Input section consists of 3 sensors, namely, Soil Moisture, Passive Infra Red, and DHT 11. Process section there is only Arduino Uno. And the output section consists of 4 components, namely water pump, LCD, buzzer, and servo. Automatic watering works when the value of the Soil Moisture sensor is more than 700 which means it is dry, and the water pump will turn on until the value is less than 700. The mouse repellent works when the PIR sensor detects the movement of an infrared object and will move the Servo and Buzzer.

Design and simulation of a dynamically tunable 1× 2 power splitter using MZI configuration in the telecom regime

We propose an ultra-broadband, ultra-compact and a dynamically tunable power splitter on a silicon on Insulator (SOI) platform with a 220 nm thick silicon light-guiding layer, using two multimode interference (MMI) couplers connected with graphene-based waveguides as the phase-tuning section through a Mach-Zehnder Interferometer (MZI) configuration. First, we theoretically present and demonstrate a novel design for the MMI couplers by combining the plane wave expansion method (PWEM) and the mode expansion conjecture concept. To verify the proposed theory, a center-fed MMI coupler and a MMI coupler, respectively, as the input and output sections of our proposed device, are designed and simulated. The simulation results achieved by Lumerical FDTD show good agreement with the design theory. Then, a highly tunable graphene-embedded silicon waveguide, for the highly efficient modulation of the effective mod index (EMI), is duly designed using Lumerical Mode Solutions. As the two MZI arms, a pair of the proposed waveguides is introduced into the middle of the cascaded MMI couplers. Accordingly, the integration properties of the analytically designed MMI couplers and the numerically designed waveguide is demonstrated through our proposed device for the aim of achieving any wanted power splitting ratio. To this end, we consider the case that the real part of the EMI of the waveguide in the lower MZI arm is modulated by varying the graphene Fermi level values, being the same for all the layers belonging to the same waveguide, while that of the upper arm is constant. The corresponding power splitting ratio can be dynamically tuned in the range of All reported results assume TE polarization. The designed MZI-based splitter possesses a bandwidth of over the wavelength range from to for various power splitting ratios, maintaining the averaged insertion loss and the averaged power imbalance, respectively, below as low as and The overall footprint of the proposed device is also highly small, i.e., about

GLADS: A global-local attention data selection model for multimodal multitask encrypted traffic classification of IoT

With the rapid development of the Internet of Things (IoT), numerous of IoT devices and different characteristics in IoT traffic patterns need traffic classification to enable many important applications. Deep-learning-based (DL-based) traffic methods have gained increasing attention due to their high accuracy and because manual feature extraction is not needed. Furthermore, seek a lightweight, multitask methods that supports a “performance-speed” trade-off. Thus, we proposed the 0.11 M global-local attention data selection (GLADS) model. The core of the GLADS model includes an “indicator” mechanism and a “local + global” framework. The “indicator” mechanism is a completely different method for handling multimodal input that allows the model to efficiently extract features from multimodal input with a single-modal-like approach. The “local + global” framework for the “performance-speed” trade-off includes a “local” part to obtain the features of each patch in the model input and a Global-Local Attention mechanism in the “global” part outputs the classification results under all possible lengths. Tests on the ISCX-VPN-2016, ISCX-Tor-2016, USTC-TFC-2016, and TON_IoT datasets show that GLADS achieves better performance than several state-of-the-art baselines, ranging from 2.42% to 7.76%. Furthermore, we also propose the “indicator,” which allows the model to simply cope with multimodal input. Based on global-local attention, we analyze the relation of the input section and model performance in detail.

Investigations on Three-Section Plate-Type Electrostatic Precipitators Used in Thermoelectric Power Plants

Dust emissions must be managed and reduced as much as possible to safeguard the environment and human health. Plate-type electrostatic precipitators have been used to decrease pollution in a number of sectors, particularly for applications needing massive volumes of gas to be dedusted at high dust concentrations and temperatures. This paper examines large-capacity plate-type electrostatic precipitators with three sections used in a coal-fired thermal power plant. Using simulations and experiments, the collection efficiency (in different ways of supplying sections, without and with sections rapping), the influence of dust resistivity and a dust layer on the surfaces of collection electrodes, the electrical parameters (voltage, current density, and space charge density) for the sections of the electrostatic precipitators, and the electrical parameters of the power sources (voltage, current, power, and power factor) are studied. A higher dust resistivity will cause a change in the shape of the voltage delivered to the sections, an increase in the average voltage from sections, and a decrease in collecting efficiency (by a few percent). A greater degree of intermittence alters the current-voltage characteristics of the sections, decreases the current across the sections, and improves collection efficiency. The density of space charges increases with the degree of intermittency and is highest at the input section. With increasing thickness of the dust layer on the collection electrodes, the collection efficiency increases. PM10 dust particles (which have a lower migration speed) are the hardest to collect with ESPs. When the sections are rapping, PM 20–30 dust particles are more difficult to collect because their migration speeds decrease significantly (compared to the situation when the sections are not rapping). The operation of the power sources of the ESP sections is dynamic, being controlled by the regulators, and the current (or current density), depending on the voltage characteristics, changes permanently (at intervals of a few seconds). The power sources of the sections are deforming consumers (the current is much different from the sinusoidal form).

An evaluation of the effectiveness of the English Upgrading program for TOEFL in an Indonesian university using the CIPP model

Human resources capacity building is a vital part of institutional development, especially in the educational field, such as the university. As an academic language, English skills are highly needed among lecturers to improve the quality of institutions in general. What is the effectiveness of an English preparation course for lecturers in an Indonesian university during the pandemic time? Using Stufflebeam’s CIPP model, this study aims to measure the quality and make recommendations on what should be improved or changed from such activity. There were 25 participants, two tutors, and one program coordinator involved as an informant. An online questionnaire was administered, as well as an in-depth interview with the tutors, coordinator, and selected participants. The results show that (1) the context is suitable to the condition, resources, and needs of the institution as well as participants. (2) In the Input section, the curriculum and variations in learning methods need to be further developed. (3) In the process section, the obstacles faced were the lecturer’s workload, which should be adjusted during the course to make them focus on the program. (4) In the product section, a high level of satisfaction was found among the participants, with an overall positive review of its merit. There is still room for improvement. One of them is to follow up on participants’ progress after the program is ended. An evaluation sheet or survey should be administered after the program is finished to assess the quality of the tutors and participants’ satisfaction with the training.

HISTORICAL EMPATHY; THE OPPORTUNITIES, REALITY, AND CHALLENGES OF ONLINE HISTORY LEARNING IN SENIOR HIGH SCHOOL

After two years of online learning, an evaluation is needed to assess whether the changes and adaptations in the process could achieve its objectives. Some adaptations had been done at UPI Laboratory School/s but no study has been conducted to assess its practice and success. Using the sequential exploratory mixed-method with the CIPP Stufflebeam model as a research framework, three teachers and 112 students from two UPI Laboratory Senior High Schools participated in this project. In-depth interviews were conducted with teachers, while online questionnaires were independently developed, validated, and distributed to students. It can be concluded that historical empathy in online learning at UPI Laboratory School/s; 1) is contextually appropriate to the conditions, resources, and needs of the institution and teachers but only part of the participants or students; 2) For Input section, aspects of the ability and capacity of teachers need to be improved; 3) As Process section, the teacher's workload and time constraints are the obstacles faced, and 4) in the Product section, the level of satisfaction among the participants varies with the theoretical aspects, dominating the practical outcomes of historical empathy-based learning. Overall, the learning program fulfilled the merit of being retained with some basic improvements.

Design of the Radio Frequency Section of a Ka-Band Multiple Beam Ladder-Type Extended Interaction Klystron

Ka-band frequencies are becoming increasingly popular due to their application potential in high-data-rate wireless communications relevant to 5G applications, satellite link establishment, etc. High-power amplifiers in this frequency band, offering several tens of watts of output RF power, are one of the main enabling components of these communication systems. This article reports the design studies and analysis of the radio frequency (RF) section of a multiple beam-extended interaction klystron (MB-EIK). The proposed multiple beam RF section with a ladder-type EIK structure offers several crucial features, such as a low-voltage operation, moderate operational bandwidth, and high output power. Starting from the design of the intermediate cavities, the input and output sections and the overall RF section are presented. The proposed RF section supports the operation at 28.5 GHz center frequency with about a 500 MHz 3 dB bandwidth employing four electron beams with a 4 kV DC accelerating field.

MLReal: Bridging the gap between training on synthetic data and real data applications in machine learning

Among the biggest challenges we face in utilizing neural networks trained on waveform (i.e., seismic, electromagnetic, or ultrasound) data is its application to real data. The requirement for accurate labels often forces us to train our networks using synthetic data, where labels are readily available. However, synthetic data often fail to capture the reality of the field/real experiment, and we end up with poor performance of the trained neural networks (NNs) at the inference stage. This is because synthetic data lack many of the realistic features embedded in real data, including an accurate waveform source signature, realistic noise, and accurate reflectivity. In other words, the real data set is far from being a sample from the distribution of the synthetic training set. Thus, we describe a novel approach to enhance our supervised neural network (NN) training on synthetic data with real data features (domain adaptation). Specifically, for tasks in which the absolute values of the vertical axis (time or depth) of the input section are not crucial to the prediction, like classification, or can be corrected after the prediction, like velocity model building using a well, we suggest a series of linear operations on the input to the network data so that the training and application data have similar distributions. This is accomplished by applying two operations on the input data to the NN, whether the input is from the synthetic or real data subset domain: (1) The crosscorrelation of the input data section (i.e., shot gather, seismic image, etc.) with a fixed-location reference trace from the input data section. (2) The convolution of the resulting data with the mean (or a random sample) of the autocorrelated sections from the other subset domain. In the training stage, the input data are from the synthetic subset domain and the auto-corrected (we crosscorrelate each trace with itself) sections are from the real subset domain, and the random selection of sections from the real data is implemented at every epoch of the training. In the inference/application stage, the input data are from the real subset domain and the mean of the autocorrelated sections are from the synthetic data subset domain. Example applications on passive seismic data for microseismic event source location determination and on active seismic data for predicting low frequencies are used to demonstrate the power of this approach in improving the applicability of our trained NNs to real data.

Concept and realization of a modular and versatile platform for metal oxide semiconductor gas sensors

Abstract To meet the requirements for high quality data capturing of metal oxide semiconductor (MOS) gas sensors, a platform is presented that can handle a large variety of sensors. Besides manufacturer modes, the platform is able to run sensors in temperature cycled operation (TCO). A system concept is presented that provides hardware modules to adapt to different MOS types like analog/digital or thin film/thick film. For analog sensors, an analog frontend with two different power variants handles the different power demands of thick film and thin film sensors. The concept and realization of the analog frontend is shown. For digital sensors, a generalized design with digital signal input sections was developed to receive data via I2C, SPI, or UART. A single microcontroller model constitutes the core of each board variant and it is flashed with a unified firmware which manages the module specific tasks. For continuity and usability, a graphical user interface (GUI) is presented that allows the user to modify measurement parameters and monitor the measurement. GUI and firmware are tuned to one another and exchange data and information to perform user commands. The validation of the accuracy of the analog temperature control is discussed and the successful usage of the system in various applications like indoor air quality (IAQ) is shown.

Thermal analysis of horizontal earth-air heat exchangers in a subtropical climate: An experimental study

The earth-air heat exchanger (EHX) has a promising potential to passively save the energy consumption of traditional air conditioning systems while maintaining a high degree of indoor comfort. The use of EHX systems for air conditioning in commercial and industrial settings offers several environmental benefits and is capable of operating in both standalone and hybrid modes. This study tests the performance and effectiveness of an EHX design in a sandy soil area in Baghdad, Iraq. The area has a climate of the subtropical semi-humid type. Ambient air temperatures and soil temperatures were recorded throughout the months of 2021. During the months of January and June, the temperatures of the inlet and outflow air at varying air velocities were monitored concurrently in 10-min increments at each location. Further numerical and thermodynamical analyses of the measurements were conducted to reveal the influencing performance parameters. The highest temperature rises of air between the input and exit sections were determined as 12.3°C (January) and 17.2°C (June). It is found that the maximum values of effectiveness are 0.80 and 0.81, while coefficients of performance are 1.6 and 1.8 for January and June, respectively. It is also found that the EHX shows good functionality and effectiveness, with potential energy savings for equipment for cooling and heating under different weather conditions.

Modular DC‐DC converter with reduced current ripple and low voltage stress suitable for high voltage applications

AbstractIn this paper, a couple inductor‐based dc‐dc boost converter with extensible capability is presented. In the proposed converter, attaching extensions to input section alleviates input current ripple. Furthermore, the current sharing performance between different phases operates beneficially by expanding optimized boost converters, especially when a partial inequality exists among different switches' duty cycles and leakage inductances. The voltage conversion ratio of the proposed converter is also additionally optimized by a series of VMR's output capacitors. Meanwhile, not only the voltage stress upon the main switches is decreased but also the all switches are managed to be turned on with zero current switching technique. The voltage spikes across MOSFETs are eliminated by using the recycling energy of leakage inductances on the clamp capacitor. The topology of the proposed converter, steady‐state analysis, and design procedure is presented to indicate the merits of the suggested converter. A prototype circuit with a three‐phase interleaved boost converter, two number of diode‐capacitor in each VMR, and output power 660 W and 40–800 V conversion ratio is experimented to corroborate the validity of the presented structure.

Evaluasi Penggunaan Sistem Informasi Tuberkulosis dengan HOT-FIT Framework di Puskesmas Mergangsan Yogyakarta

Background : The Tuberculosis Information System (SITB) is an application for recording and reporting TB cases designed by the Indonesian’s Ministry of Health in electronic form. This system is used by TB surveillance programmers at the primary health care (namely : Puskesmas), but in its use there are several obstacles including the system which sometimes becomes slow during the data input process and features that are felt to be incomplete. The purpose of this study was to evaluate the use of SITT at Puskesmas Mergangsan, Yogyakarta using the HOT-Fit Framework approach.
 Method : This research design is a qualitative research through descriptive case studies by conducting in-depth excavations through an in-depth interview process and document review regarding the input, process and output of the integrated tuberculosis information system and its contribution to decision making. The informants in this study were the Head of the Puskesmas, SITB Programmers, laboratory and pharmacy staff who used SITT and the deputy supervisor (wasor) from the health office district of Yogyakarta city. The sample selection uses a porpusive sample, namely the selection of samples with certain criteria that are considered to be able to answer the research problem.
 Results : Assessment of human factors at SITB is known that system users have received training before the system is used so that the system can be easily used, users are satisfied with the system that has been provided. Assessment of Organizational Factors, it is known that officers who use SITB at Puskesmas Mergangsan are sufficient, namely there are programmers, SITB in charge of the laboratory and SITB in charge of pharmacy, there is supporting facilities from Puskesmas Mergangsan, namely the procurement of laptops. Evaluation is carried out by the Dinas Kesehatan Kota Yogyakarta every three months. Technological Factor Assessment, the quality of the information produced depends on the accuracy of the data entered by health workers, there is still incomplete or clear information. The quality of system services is supported by the provision of a communication and coordination group by the Dinas Kesehatan Kota Yogyakarta.
 Conclusion : The implementation of SITB at the Puskesmas is still constrained in the input section of network facilities which has an impact on the data input process which cannot be done quickly, thus requiring support from the Puskesmas. It is hoped that there will be periodic socialization carried out by the Dinas Kesehatan Kota Yogyakarta as an evaluator of SITB users at the Puskesmas so that the use of SITB is more optimal
