Enhanced Glycerolysis of Fatty Acid Methyl Ester by Static Mixer Reactor.

This study investigates the synthesis of monoglycerides (MGs) and diglycerides (DGs) from glycerol (G) and fatty acid methyl ester (FAME) using a static mixer reactor (SMR), which combines a static mixer (SM) with a reactor tank. The SMR integrates Kenics static mixers (KSM) and low-pressure drop static mixers (LPDSM) with varying length-to-diameter ratios (L/D = 1.0 and 1.5). Keys glycerolysis parameters, including the G:FAME molar ratio of 2:1-3:1, 2-3 wt % potassium hydroxide (KOH), and reaction time of 30-90 min at 150 °C were systematically explored. The SMR design allows precise control over the reaction time without altering the feed flow rate or tube length and avoiding agitator leakage. The optimal operating conditions, determined through a face-centered central composite design, resulted in 71.35% MGs and 14.20% DGs at a 3:1 molar ratio of G to FAME, 3 wt % KOH, 60 min, and 150 °C using an LPDSM with an L/D of 1.5. In comparison, an LPDSM with an L/D of 1 achieved 79.28% MGs and 10.17% DGs under the same conditions. When applied to purified crude glycerol, these conditions yielded 61.09% MGs and 23.44% DGs. The study found that a lower L/D ratio improved the mixing efficiency but increased the pressure drop. The SMR demonstrated superior performance in glycerolysis compared with conventional stirred tank reactors and ultrasonic probe reactors, indicating its potential for enhanced industrial application.

— Smart and wearable devices for visually impaired individuals have advanced significantly, but often face limitations such as limited functionality, high cost, and usability issues. Despite numerous studies and available solutions, providing comprehensive and accessible support remains challenging. This study identifies these gaps through various literature reviews and market analyses, proposing an innovative approach by integrating ultrasonic sensors with the Arduino Pro Mini board to create a 'third eye for the blind.' This device uses ultrasonic waves to detect obstacles and alerts users with buzzer sounds or vibrations, enabling confident and swift navigation. Leveraging advancements in computer science, electrical engineering, and medicine, this solution addresses the limitations of traditional aids like the white cane. According to WHO, 39 million people globally are visually impaired, facing significant daily challenges. Existing technologies offer alternatives, but the given solution uniquely enhances mobility by allowing users to locate and recognize objects in their vicinity, providing alerts through vibrations or beeps when objects are detected. This approach offers a practical, cost-effective, and user-friendly alternative, significantly improving the quality of life for visually impaired individuals by enhancing their ability to travel safely and independently.

Control of tungsten-epoxy composite porosity prepared using a high-energy ball milling method: An engineering aspect of backing layer fabrication

Tungsten-epoxy composite is commonly used as a backing layer substrate of piezoelectric-based ultrasonic transducers. The physical properties of this composite, such as porosity, play a significant role in controlling the behavior and specifications of transducer fabrication. Therefore, this study aimed to investigate the effects of tungsten content in epoxy to control porosity and determine the engineering aspects of ultrasonic transducer fabrication. The experiment was conducted using a shaker-type high-energy ball milling method, where non-spherical and faceted tungsten particles with a mean size of 1 μm were composited into epoxy resin as a matrix at various tungsten-epoxy weight ratios of 0:1 to 10:1. The prepared composite surface morphological and elemental, tungsten loading, particles, and epoxy bonding were examined and analyzed. Furthermore, analysis was carried out on the relationship between tungsten content and the parameters corresponding to the composite acoustic characteristics, such as sound velocity, acoustic attenuation, and acoustic impedance. The results showed that composite porosity increased in the range of 12.40–31.87%, corresponding to acoustic impedance from 3.04 to 9.37 Mrayl (below 10 Mrayl for biomedical ultrasonic transducers) when the tungsten-epoxy weight ratio varied from 0:1 to 10:1. This showed the significant influence of tungsten particle loading on controlling porosity of tungsten-epoxy composite by precisely tuning the weight ratio, contributing to engineering process in the fabrication. In conclusion, porosity was adjusted by controlling the tungsten loading content in epoxy.

Implementation of smart wheelchair with obstacle avoidance

The primary goal of this work is to develop a dependable and efficient solution for maintaining optimal mobility in wheelchair systems. The aim is to enhance functionality and reduce the user’s physical effort required to move the wheelchair wheels. The proposed system integrates advanced sensing technology, intelligent control algorithms, and robust hardware components to manage the wheelchair, detect obstacles, and eliminate the need for external assistance. This wheelchair employs joystick control and halts when the system senses an obstacle. The system enhances user autonomy by providing ease of control and ensures safety by detecting and avoiding obstacles. Motor speeds are adjusted based on joystick input, and the motor direction (forward, backward, left, right) is determined accordingly. An ultrasonic sensor measures obstacle distance, and if an obstacle is detected (distance <= 20cm), both motors stop, and a warning buzzer activates for 1 second. If no obstacle is detected, the warning buzzer turns off, and motor speeds are adjusted based on joystick input. The system effectively demonstrated obstacle avoidance by changing direction when a command was issued away from the obstacle. The outcomes of this study contribute valuable insights to the field of wheelchairs, specifically in the realm of obstacle avoidance.

Generative domain-adapted adversarial auto-encoder model for enhanced ultrasonic imaging applications

In this study, we propose a class-conditioned Generative Adversarial Autoencoder (cGAAE) to improve the realism of simulated ultrasonic imaging techniques, in particular the Multi-modal Total Focusing Method (M-TFM), based on the availability of both simulated and experimental TFM images. In particular, this work studied the case of the inspection of a complex geometry block representative of weld-inspection problem based on ultrasonic multi-elements probe. The cGAAE is represented by a tailored learning schema, trained in a semi-supervised fashion on a labeled mixture of synthetic (class 0) and experimental (class 1) M-TFM images, obtained under different meaningful inspection set-ups parameters (i.e., the celerity of the transverse ultrasonic wave, the specimen back-wall slope and height, the flaw tilt and heigh). That is, the cGAAE schema consists in a combination of learning stages involving class-conditioned spatial-transformers and arbitrary style transfer endows the cGAAE of powerful generative features, such as quasi real-time generation of M-TFM images by sweep of the inspection parameters. We exploited the cGAAE model to improve the realism of simulated M-TFM images and enhance the accuracy of the inverse problem, aiming at estimating the inspection parameters based on experimental acquisitions.

Fabrication of BiScO3–PbTiO3/epoxy 1–3 piezoelectric composites for high‐temperature transducer applications

Abstract1–3 piezoelectric composites are widely used in piezoelectric ultrasonic transducers due to their high thickness electromechanical coupling factor. However, the applications of the composites in high‐temperature fields are limited by the low heat resistance of both the piezoelectric and polymer phases. To tackle this, we designed and fabricated the BiScO3–PbTiO3/epoxy high‐temperature 1–3 piezoelectric composites. These composites exhibit a high thickness electromechanical coupling factor kt of 63%, a large piezoelectric coefficient d33 of 470 pC/N, and a pure thickness vibration mode. Furthermore, we fabricated a high‐temperature transducer based on the BiScO3–PbTiO3/epoxy 1–3 composites. The bandwidths of the composites measured in water and silicone oil (30% and 23%, respectively) are approximately 1.65 times greater than those of monolithic piezoelectric ceramics (18% and 14%, respectively). The bandwidth of the transducer can be increased to 78% by adding a porous alumina backing layer, with the working temperature reaching up to 300°C. The results indicate that the BS–PT/epoxy 1–3 composite is a potential candidate for high‐temperature transducer applications.

Arrayed ultrasonic wind speed and direction measurement based on the BNF-FLOC-MUSIC algorithm

An arrayed ultrasonic wind measurement method based on the BNF-FLOC-MUSIC algorithm is proposed to address the issue of low measurement accuracy and poor noise suppression capabilities of current array wind measurement methods in impulse noise backgrounds. The proposed method utilizes an array structure consisting of one transmitting ultrasonic sensor and five receiving sensors. Continuous sampling is performed leveraging this structure, and the received array signals are processed using a bounded nonlinear function (BNF). Subsequently, the fractional lower-order covariance (FLOC) operations are applied to suppress impulse noise’s influence further. Finally, combining these steps with the Multiple Signal Classification (MUSIC) algorithm enables high-precision wind speed and direction measurement. The effectiveness and superiority of the method are examined through simulation experiments and actual measurement systems, and the errors of wind speed and wind direction angle in actual measurement are 1.2% and 2°, respectively, which satisfy the design requirements of the ultrasonic anemometer.

Safety and effectiveness of controlled ovarian stimulation and oocyte retrieval during prepubertal and peripubertal period.

Is itsafe and effective to perform controlled ovarian stimulation (COS) and oocyte retrieval (OR) in prepubertal and peripubertal patients? In this retrospective cohort study, data of 20 pre-/peripubertal patients who underwent COS and OR for the purpose of oocyte cryopreservation (OC) between 2008 and 2023 were reviewed.Following COS, all OR procedures were performed transabdominally using a vaginal ultrasound probe. Ovarian reserve was assessed by serum FSH, LH, estradiol, AMH, and antral follicle counts (AFC) in all subjects. All mature oocytes were vitrified. Mean age of the patients was 15.05 ± 1.87, mean AMH was 0.84 ± 0.8ng/ml, mean FSH was 6.39 ± 3.95IU/L, mean estradiol was 61.6 ± 51.9pg/ml, mean LH was 4.69 ± 3.46IU/L, and mean AFC was 5.5 ± 5.82. Among the patients, 12 had regular menstrual cycle, 5 had irregular menstrual cycle, whereas 3 patients still did not have their menarche yet. The indications for OC were as follows: primary ovarian insufficiency (n = 7), ovarian surgery for ovarian tumors (n = 5) or ovarian torsion (n = 1), mosaic Turner syndrome (n = 2), acute lymphoblastic leukemia (n = 1) anaplastic B-cell lymphoma (n = 1), Ewing's sarcoma (n = 1), Noonan syndrome (n = 1), and Thalassemia (n = 1). The mean number of oocytes retrieved, MII oocytes frozen, and maturation rate were 5.11 ± 5.0, 3.92 ± 4.48, and 75.1 ± 25.6%, respectively.Stepwise linear regression analysis demonstrated a positive correlation between AFC and number of total oocytes retrieved and number of MII oocytes. In the case diagnosed with Noonan syndrome, all 7 retrieved oocytes were MI and all frozen at MI phase. No patient had any complication related to COS or OR. Even though number of the enrolled subjects is limited and mean AMH is lower in our cohort, we demonstrated that performing COS and OR is safe in pre-/peripubertal patients. If required, transabdominal route can be performed in this age group for OR. AFC appears as a prognostic factor for stimulation outcome in this age group. Pediatric patients or young adolescents at risk for primary ovarian insufficiency should not bediscouragedfrom utilizing OC.

The IoT-Based Early Warning System for Detecting High Tide Floods (ROB-EWS) in Tambak Lorok, Semarang Indonesia

Background and Objectives: The Tambaklorok fishing village area, located on the northern coast of Semarang City, Indonesia, is susceptible to sea level fluctuations, which often lead to tidal flooding and seawater encroaching into residential areas. Consequently, a seawater flood detector (rob) is needed for effective disaster mitigation for affected communities. This study aims to implement a disaster mitigation system by installing an IoT-based Seawater Flood (Rob) Early Warning System to reduce disaster risks and their impacts on the community. Methods: The IoT-based Early Warning System is designed to detect floods by monitoring sea level height parameters. Results: IoT-based devices measure sea level using ultrasonic sensors, with the readings processed by a microprocessor. The data is then periodically analyzed and transmitted to an application in real-time. This technology allows for real-time information dissemination through web applications and alerts in the form of sirens. These warnings enable residents to evacuate and move to safer areas. The siren alerts are categorized into two levels: Alert 1 indicates that seawater is approaching the land boundary, while Alert 2 signals that water has begun to enter residential areas. Additionally, designated evacuation zones will guide affected communities to safer areas. Conclusion: The installation of an IoT-based Early Warning System delivers real-time information to help mitigate the impact of rising sea levels (rob) in the Tambak Lorok fishing village community.

Focus control of a concave–convex ultrasonic gel lens in the radial direction

Optical image stabilization (OIS) systems maintain the three-dimensional focal position of a lens through mechanical actuation systems. This paper examines an optical lens for OIS that utilizes ultrasound vibration to alter the focal position, not only in the depth direction but also in the radial direction. The lens has a simple structure with no mechanical moving parts and consists of an ultrasound transducer divided into four pieces, a glass disk, and a transparent viscoelastic gel film that functions as a lens. The acoustic radiation force generated by the resonant flexural vibration of the glass disk can alter the surface profile of the gel film, allowing for a variable-focus function. The concave and convex lenses can be interchanged using two resonant vibration modes: the standing-wave mode, in which the vibration loop appears at the center, and the traveling-wave mode, in which the vibration node appears at the center. The positions of ultrasound vibrations on the lens can be controlled in a two-dimensional plane by adjusting the driving amplitudes of each channel, thereby achieving focus control in the radial direction. The focusing characteristics of the lens are evaluated through ray-tracing simulation.

Ultrasonic imaging of concrete-embedded corroded steel liners using linear and nonlinear evaluation

ABSTRACT This study explores the efficacy of horizontally polarised shear (SH) waves in ultrasonic inspection of concrete-embedded steel liner plates, focusing on corrosion detection. SH-waves are found to significantly improve the localisation and potential dimensional assessment of embedded plate-like structures compared to compressional (P) waves, as evidenced by SH C-scans. Anomalies corresponding to severe corrosion are discernible in SH C-scans, whereas they are minimally visible in P-wave scans. Nonlinear evaluation explores harmonic-based imaging, including second harmonic generation (SHG) and third harmonic generation. Nonlinear SH-wave evaluation accurately locates the most severely corroded embedded plate, whereas comparative P-wave evaluations fail. However, potential FFT sidelobe contamination in the results warrants consideration. These results suggest a promising use for nonlinear waveform distortion in SH-wave-based corrosion detection though conclusive evidence of the source of SHG is uncertain. Experiments utilised an automatic scanner system for consistent control. The concrete specimen investigated herein contained pre-corroded plates which hint at heightened nonlinear effects when corrosion occurs post-embedment due to corrosion-induced cracking. These findings encourage further investigation into SH-waves for nonlinear ultrasonic detection of concrete-embedded steel liner plates and the development of instrumentation tailored to such methods.

The Analysis Of Ultrasonic Sensors In Smart Trash Bin Technology Based On Arduino Nano Microcontroller

Waste is an environmental problem that is increasing along with population growth and public consumption. To solve this problem, an automatic device that controls the opening and closing of the trash can without direct touch is developed using an Arduino Nano microcontroller, HC-SR04 ultrasonic sensor, VL53L0X LIDAR, and MG996R servo motor. This research aims to evaluate the responsiveness of the sensor in detecting objects, the effect of the interaction of distance, angle, and object thickness on the sensor response time and aims to determine the effect of garbage volume on the response time of the indicator LED light. The test was conducted using the experimental method of distance variation of 20 cm, 30 cm, 40 cm, and 50 cm; angle variation of 0°, 10°, and 20°; and thickness variation of 10 mm, 65 mm, and 120 mm. Data analysis using multiple linear regression research methods shows a P-Value of 0.409 for the ultrasonic sensor with ɑ of 0.05, if the P-Value > ɑ, then H0 is accepted and H1 is rejected which mean that there is no significant effect of the interaction between distance, angle, and thickness of the object on the response time of the trash can lid opening sensor.

Real-time tracking of the Bragg peak during proton therapy via 3D protoacoustic Imaging in a clinical scenario

Proton radiotherapy favored over X-ray photon therapy due to its reduced radiation exposure to surrounding healthy tissues, is highly dependent on the accurate positioning of the Bragg peak. Existing methods like PET and prompt gamma imaging to localize Bragg peak face challenges of low precision and high complexity. Here we introduce a 3D protoacoustic imaging with a 2D matrix array of 256 ultrasound transducers compatible with 256 parallel data acquisition channels provides real-time imaging capability (up to 75 frames per second with 10 averages), achieving high precision (5 mm/5% Gamma index shows accuracy better than 95.73%) at depths of tens of centimeters. We have successfully implemented this method in liver treatment with 5 pencil beam scanning and in prostate cancer treatment on a human torso phantom using a clinical proton machine. This demonstrates its capability to accurately identify the Bragg peak in practical clinical scenarios. It paves the way for adaptive radiotherapy with real-time feedback, potentially revolutionizing radiotherapy by enabling closed-loop treatment for improved patient outcomes.

A compact and low-frequency drive ultrasound transducer for facilitating cavitation-assisted drug permeation via skin.

Low-frequency sonophoresis has emerged as a promising minimally invasive transdermal drug delivery method. However, effectively inducing cavitation on the skin surface with a compact, low-frequency ultrasound transducer poses a significant challenge. This paper presents a modified design of a low-frequency ultrasound transducer capable of generating ultrasound cavitation on the skin surfaces. The transducer comprises a piezoelectric ceramic disk and a bowl-shaped acoustic resonator. A conical slit structure was incorporated into the modified transducer design to amplify vibration displacement and enhance the maximum sound pressure. The FEM-based simulation results confirmed that the maximum sound pressure at the resonance frequency of 78 kHz was increased by 1.9 times that of the previous design. Ultrasound cavitation could be experimentally observed on the gel surface. Moreover, 3 min of ultrasound treatment significantly improved the caffeine permeability across an artificial membrane. These results demonstrated that this transducer holds promise for enhancing drug permeation by generating ultrasound cavitation on the skin surface.

Sustainable ultrasonic extraction of antibacterial Basella alba fruit dye for cotton, silk, and leather

Alternative to synthetic dyes containing harmful compounds, dyes derived from natural sources are gaining popularity due to their safer and eco-friendly nature. This study focuses on extracting red dye from Basella alba fruit and optimising the extraction methods, including ultrasonic bath, ultrasonic probe, and direct heating. The extracted dye was then used for dyeing cotton, silk, and leather without needing a mordant. Furthermore, the antibacterial properties of the extracted red dye were evaluated against skin bacteria. The UV–Visible spectrophotometric analysis revealed that the maximum red colour in the methanol extract (λmax 270 and λmax 542 nm) was achieved at 60 °C for 30 min using the ultrasonic water bath extraction method, followed by the ultrasonic probe and direct heating methods. The FTIR spectra confirmed the presence of flavonoids, betacyanin, and gomphrenin-I in the extracted dye. The ultrasonic dyeing process at 50 °C yielded a K/s value 6.3 for the dyed cotton, silk, and leather without using a mordant. Additionally, the fatness test indicated a high grade of 0.5–1.5 for the ultrasonic dyeing method compared to other dyeing techniques. The extracted dye exhibited significant antibacterial activity against all Pseudomonas sp. after extraction in methanol, with the highest inhibition observed against Pseudomonas sp. with a MIC of 1.56 mg/ml.

StepSafe Cane: Empowering Confident Steps for a Healthier Future

Mobility is the capability of one to get to another place. Vision is defined as the faculty and power of seeing. As technology develops and grows, several devices and tools have aided those with mobility issues or impairment and those who are visually impaired. For those who are visually impaired, the traditional aid has been the white cane for a long time which only helps them navigate their way and detect obstacles without providing physical support. While those with mobility issues use a walking stick which does not help them in detecting surrounding obstacles. For those with both mobility issues and visual impairment, this becomes a problem as it is uncommon for a gadget or aid to tackle both these issues at once. The Smart Guide Cane is specially designed for this group of people with both issues. It can also help those with any of the two issues as it has many features that will allow them to be more confident in their movement, improving the quality of life for the disabled. Many steps have been taken in developing the Smart Guide Cane. A program was coded and simulated together with the circuit to ensure the functionality of the program. Then, the physical prototype was created, using Arduino UNO, HC-SR04 (ultrasonic sensor), MPU6050 (fall detector), TTP223 (touch sensor), vibration motor and buzzer as its main components. Tests have been done using this prototype circuit to demonstrate the feasibility and functionality of the Smart Guide Cane. From the prototyping and testing, it can be seen that all the components would function as intended in the Smart Guide Cane.

The cultivation system using hydroponics is now widely popular among the community because it does not require large areas of land. Using the hydroponic system results in faster and optimal harvests. However, the busy activities of urban communities often cause them to fail in implementing it due to constraints in controlling and monitoring hydroponic plants. Additionally, PLN electricity is essential for operating the water pump, and the electricity load and tariff increases, along with sudden blackouts, significantly impact business actors. To address this problem, this research creates an Internet of Things (IoT)-based water monitoring system for ACONE Hydroponics partners with solar panel (PLTS) energy sources as an alternative energy in the event of a sudden PLN power outage. The sensors used in this system include the HCR-04 ultrasonic sensor to monitor water availability and the water flow sensor to measure water flow (discharge). Sensor data is processed by the ESP32 microcontroller and sent to the Blynk cloud platform via an internet connection and displayed on an LCD. System testing shows that the system can send sensor data to the cloud platform stably and in real-time. Data visualization on the cloud platform is easy to understand and helps hydroponic owners monitor water conditions in hydroponic systems. This water monitoring system can help users optimize water use in hydroponic systems.

A tunable spatial coherence imaging with ultrasonic array for defects in composites

ABSTRACT Ultrasonic phased array detection technology is a promising non-destructive testing (NDT) method that has been widely used for defect detection. Due to the high attenuation characteristics of ultrasonic wave propagation in carbon fibre reinforced polymer (CFRP) and the directivity of the array elements, the possibility of false or missed detection for defects that are far from the array elements or located very close together will increase. In addition, the total focusing method (TFM) employs only the defect information contained in the full matrix capture (FMC) dataset while ignoring the spatial information of the array signals, leading to image mixed with artefact and noise. An improved method called p-weighted-TFM (p-WTFM) is proposed. First, this method scales the magnitude of time-delayed channel signal by p-th root while maintaining the phase unchanged. Second, channel summation with energy compensation and directional correction will be realised. Finally, the signal dimensionality is restored by p-th power. Experimental results show that the p-WTFM can use any rational p-value to flexibly adjust image quality. Specially, this method can accurately distinguish adjacent defects spaced 1 mm apart with p value of 2.5, and it can also detect two defects located 10 mm deep with p value of 3.0.

A low-voltage-driven MEMS ultrasonic phased-array transducer for fast 3D volumetric imaging

Wearable ultrasound imaging technology has become an emerging modality for the continuous monitoring of deep-tissue physiology, providing crucial health and disease information. Fast volumetric imaging that can provide a full spatiotemporal view of intrinsic 3D targets is desirable for interpreting internal organ dynamics. However, existing 1D ultrasound transducer arrays provide 2D images, making it challenging to overcome the trade-off between the temporal resolution and volumetric coverage. In addition, the high driving voltage limits their implementation in wearable settings. With the use of microelectromechanical system (MEMS) technology, we report an ultrasonic phased-array transducer, i.e., a 2D piezoelectric micromachined ultrasound transducer (pMUT) array, which is driven by a low voltage and is chip-compatible for fast 3D volumetric imaging. By grouping multiple pMUT cells into one single drive channel/element, we propose an innovative cell–element–array design and operation of a pMUT array that can be used to quantitatively characterize the key coupling effects between each pMUT cell, allowing 3D imaging with 5-V actuation. The pMUT array demonstrates fast volumetric imaging covering a range of 40 mm × 40 mm × 70 mm in wire phantom and vascular phantom experiments, achieving a high temporal frame rate of 11 kHz. The proposed solution offers a full volumetric view of deep-tissue disorders in a fast manner, paving the way for long-term wearable imaging technology for various organs in deep tissues.
