Authors: Liu Shangjunnan , Liu Shuhai , Xiao Huaping
Published: January 2024

Due to the compact parking of vehicles in parking lots, the working environment of electric vehicle charging robots is complex and narrow, which puts higher demands on the flexibility of robot manipulators. The workspace of manipulator reflects its working range, while the density of the workspace reflects the flexibility of all parts of the manipulator within its working range. According to the working range of the electric vehicle charging robot, adjusting the ratio of the number of manipulator joints and the length of the manipulator can improve its dexterity. This article uses MATLAB simulation to calculate the workspace density of manipulator with different joint numbers and length ratios, and draws workspace density cloud map, which can more intuitively judge the performance of the manipulator. The research provides guidance and inspiration for optimizing the geometric dimensions of the manipulator.

Published: January 2024

Addressing the challenge of autonomous navigation for mining Unmanned Ground Vehicles (UGVs) in mining environments, this paper introduces a comprehensive navigation framework tailored to bumpy terrains, integrating improved obstacle recognition with localized obstacle avoidance techniques. The algorithmic realization of this framework involves four key stages. The first stage involves 3D mapping and localization of the environment. It is achieved through the fusion of a radar LiDAR-Visual Inertial SLAM System (LVI-SAM) and Monte Carlo Localization (MCL) algorithms. In the next stage, dense global paths are generated using Plane Fitting Rapidly Expanded Random Tree (PF-RRT*) and Gaussian Process Regression (GPR). In the third stage, an improved Density-Based Spatial Clustering of Applications with Noise (DBSCAN*) is employed to address the obstacles around the UGV, and these obstacles are encapsulated using adaptive cylindrical envelopment. In the final stage, an Adaptive Control Barrier Function (A-CBF) is proposed to be used in combination with Model Predictive Control (MPC) to aid in dynamic obstacle avoidance and global trajectory tracking. The algorithmic framework’s effectiveness is confirmed through simulation experiments in the Gazebo software and real-world navigation tests conducted in mining environments, with the results exhibiting the UGV’s precise target-reaching abilities.

Published: January 2024

In this paper, we present a digital microfluidics (DMF) system with closed-loop feedback droplet sensing. The system is capable of controlling the movement of droplets and detecting their positions in real time, and is compatible with different numbers of DMF electrodes. The detection of the droplet position is realized by impedance sensing. When an electrode failure occurs, the system automatically performs path planning to move the droplet successfully. Besides, we designed a voltage control unit (5V DC/AC to 80V DC/AC) to realize the voltage control for different droplets. The experimental results show that the droplet position detection time is about 2 ms, and the detection accuracy reaches 100% at 100 times. With the help of the droplet sensing system, even there’s an ineffective electrode in the origin path, the droplet was able to move to the target electrode by the replanned path. The system is expected to play an important role in many biochemical experiments due to its automation and reliability.

In order to further improve the speed and precision of electronic component identification, an improved MobileNetV3 electronic component identification method is proposed. Addressing the limited capacity of channel attention in the MobileNetV3 network to capture essential information, an improved hybrid attention mechanism is proposed, which connects channel attention and spatial attention in parallel to maximize effectiveness of these two attention mechanisms for feature extraction, and combines the specific features of electronic component recognition. The network structure and the number of layers are adjusted and optimized to further shorten training time and improve the operational velocity of the model. Compared with the traditional MobileNetV3 network, the empirical results substantiate that the recognition accuracy of the improved approach in the self-built data set of components reach 95.07% and the number of model parameters is reduced by nearly 20%.

Published: January 2024

A new green air-conditioning system based on the traditional absorption air-conditioning system is proposed: the system adopts biomass waste and forms a medium cycle with capacitive deionization (CDI) technology. The key to the new system is the electrodes of CDI. In our work, corn cobs, corn stalks, and waste cigarette butts have been used to prepare micro/mesoporous carbon material for electrode fabrication. The resultant material has been characterized by BET. The electrochemical performance has been tested with electrochemical workstation. The COP has been analyzed for the new air-conditioning system with different electrode materials. The results find the suitable conditions for preparing the electrode material with excellent pore structure and higher specific surface area. It has been demonstrated that the corn cobs activated at 800 °C (CBC-800) possess the highest specific surface area of 1201.9 m2 g-1 and the highest electrochemical capacitance of 141.1F g-1 at a scan rate of 5 mV s-1. The results show that the system with LiBr solution has the highest COP, it can approach 6 with a 40 % concentration when CBC-800 is used as carbon electrodes.

Published: January 2024

In order to compare performance of different fire detection systems commonly used in urban utility tunnel, several types of fire detectors were selected to test by setting up a fire experimental bench to record the response time of detectors. In the experiment, ceramic tube electric heating and alcohol ignition were used to ignite the cable respectively so that fire detectors in the cable tunnel could give an alarm. Results show that contact-type linear temperature sensor has the fastest alarm time for ceramic tube electric heating method. The cable line-type rate-of-rise and fixed temperature detector are more stable, and the alarm times are shorter. The image fire detector did not give an alarm. As for alcohol ignition method, fire is relatively small in the early stage, the temperature in the utility tunnel is relatively low, and the fire detection response time would be long. In addition, wind velocity in the utility tunnel has a great influence on the detector alarm time.

Published: January 2024

BACKGROUND:

People with forward head posture (FHP) and rounded shoulder posture (RSP) may experience shifts in scapular position and alterations in the strength of the muscles surrounding the scapula. Therefore, a reliable scapula position and scapula muscle strength test are required to identified scapula problem and provided appropriate intervention programs.

OBJECTIVE:

This study aimed to determine the reliability of scapular position measurements obtained using a modified digital inclinometer and palpation meter, as well as muscle strength using a hand-held dynamometer (HHD) in individuals with FHP and RSP.

METHODS:

Thirty healthy subjects underwent scapular position tests (upward rotation, anterior tilt, depression, and protraction) and strength tests of periscapular muscles (serratus anterior, upper trapezius, middle trapezius, and lower trapezius) on both the dominant and non-dominant sides. The reliability of the measurements was confirmed by computing the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimal clinically important difference (MCID). Test and re-tests were conducted over a period of one week and actual values for each measurement were also obtained and assessed.

RESULTS:

The ICC ranged from 0.802 to 0.935 for the scapular position tests and from 0.808 to 0.949 for muscle strength tests on the dominant and non-dominant sides. For scapular position tests, SEM values ranged from 0.3 cm to 0.6 cm (protraction and depression), from 1.0∘ to 1.7∘ (upward rotation and anterior tilt) and MCID values ranged from 0.7 cm to 1.6 cm (protraction and depression), from 2.8∘ to 4.7∘ (upward rotation and anterior tilt). Regarding muscle strength tests, SEM and MCID values were in the range 14.4N–27.3N and 39.9N–75.7N, respectively.

CONCLUSIONS:

Scapular position and periscapular muscle strength can be reproducibly measured in healthy subjects individuals with FHP and RSP. These instruments can hence be recommended for evaluating these functional traits in subjects with FHP and RSP.

Published: January 2024

The success of deep learning in natural language processing relies on ample labelled training data. However, models in the health domain often face data inadequacy due to the high cost and difficulty of acquiring training data. Developing such models thus requires robustness and performance on new data. A generalised incremental multiphase framework is proposed for developing robust and performant clinical text deep learning classifiers. It incorporates incremental multiphases for training data size assessments, cross-validation setup to avoid test data bias, and robustness testing through inter/intra-model significance analysis. The framework’s effectiveness and generalisation were confirmed by the task of identifying patients presenting in ‘pain’ to the emergency department.

The magnetic CoFe2O4 nanoparticles, prepared by hydrothermal method combining with the heat treatment at 600oC, were used to act as a photo‒Fenton catalyst in the methylene blue (MB) degradation reaction. The composition, structure, and surface morphology of the prepared materials were studied by X-ray diffraction (XRD), Fourier-transform infrared (FT-IR) spectroscopy, field-emission scanning electron microscopy (FESEM), and energy-dispersive X-ray (EDX) spectroscopy. The optical properties of CoFe2O4 before and after calcination, analyzed by UV-Vis diffuse reflectance (DRS) spectroscopy, demonstrated that after heating at 600oC, the structure and crystallinity of CoFe2O4 were increased. The calcination process also caused the CoFe2O4 sintering to grow to a larger size, thereby reducing the surface area of the CoFe2O4 after calcination compared to the original ones. This value was determined through nitrogen the adsorption‒desorption isotherms curve. The magnetism of CoFe2O4 before and after calcination was studied by vibrating sample magnetometer (VSM). After sintering at 600oC, the saturation magnetization (Ms) and residual magnetism (Mr) of CoFe2O4 were higher than those of the original. The Fenton photocatalytic performance was evaluated by MB degradation reaction under UVA radiation in the presence of oxalic acid as an active free radical generating agent. In the methylene blue degradation reaction at room temperature, the prepared CoFe2O4 catalyst showed the maximum degradation efficiency of 97% for MB and the reaction yields were almost unchanged after three consecutive reactions. This method promised in making ferrite materials for water treatment based on some advantages such as simple process, low cost, and environmentally friendly solvent usage.

Carrying out calculations to ensure the qualitative optimization of the parameters of technical means in various categories, the organization of effective production and operational control is possible only on the basis of the creation of effective methods and algorithms for the analysis of functioning processes and the accuracy of complex structures and schematic diagrams of systems and devices that are designed and developed. When developing these methods and algorithms, a set of complex scientific problems arises, the solution of which requires a number of scientific studies. The task of assessing the impact of deviations of the parameters of nonlinear dynamic systems on their movement and quality indicators is considered. Both when analyzing the accuracy of dynamic systems and when solving synthesis problems with accuracy conditions, the ability to analytically express the additional motion of dynamic systems is of great importance. The corresponding formulas for the deviations of the trajectories of the dynamic system relative to the reference trajectory and relative to the excited motion were obtained and analyzed. A method of rational determination of interpolation nodes when calculating functionals from the initial coordinates of the dynamic system is proposed. The technique refers to the selection of Gaussian quadrature nodes when calculating the quality indicators of dynamic systems with the smallest calculation error.

Анотація. Під час російської агресії, Україна стикається із багатьма проблемами у різних сферах життєдіяльності. Через великий потік пацієнтів є надзвичайно важко забезпечити якісний протиепідемічний режим у медичних закладах, що знаходяться близько до лінії фронту. Після надання першої медичної допомоги пацієнти потрапляють до лікарень на мирних територіях для продовження стаціонарного лікування та протезування. Гнійно-септичні ускладнення вогнепальних поранень розвиваються у 50-75% випадків. Результати проведених мікробіологічних досліджень ран постраждалих внаслідок вибухових або мінно-вибухових поранень показали переважання грамнегативної мікрофлори. Стійкий до антибіотиків P. aeruginosa, що вражає рани, пов’язані з війною, є серйозною проблемою з регіональними та глобальними наслідками, яка потребує регулярного тестування на чутливість до антибіотиків. Метою дослідження було виділення псевдомонад, які ускладнюють перебіг загоєння ран, що відтермінує можливість протезування пацієнтів, визначення спектру чутливості виділених штамів до антибактеріальних препаратів. Виділені псевдомонади були резистентні практично до усіх антибіотиків, що рекомендовані для тестування керівництвом EUCAST. Перспективними дослідженнями є пошук та тестування нових протимікробних засобів, що володіють високою активністю відносно резистентних ізолятів P. aeruginosa.

У статті визначено ступінь деструкції рослинних решток кукурудзи за дії мікробних препаратів. Одним із способів активізації та прискорення процесу розкладання рослинних решток є використання мікробіологічних препаратів – деструкторів, що містять у своєму складі селекціоновані високоефективні штами та консорціуми мікроорганізмів-целюлозолітиків. Біодеструктор Екостерн бактеріальний – препарат на основі штамів агрономічно цінних бактерій для розкладання рослинних решток, стимуляції росту й розвитку рослин, захисту від фітопатогенів, Триходермін – високоефективний, екологічно безпечний препарат, який виготовляється на основі гриба Trichoderma viride з антагоністичними та целюлозолітичними властивостями. За результатами досліджень нами виявлено високу ефективність застосування біодеструкторів стерні для прискорення розкладання рослинних решток кукурудзи завдяки збільшенню кількості корисних мікроорганізмів у ґрунті, які є відповідальними за процеси біодеструкції. Характер дії біодеструкторів суттєво різнився упродовж періоду дії препаратів. Так, через півроку після внесення деструкторів ступінь розкладання рослинних решток кукурудзи у ґрунті на варіанті із застосуванням Триходерміну становив 13,4 %, а Екостерну – 15,2 %. На восьмий місяць деструкції інтенсивність розкладання рослинних решток збільшилась у 2,5–3 рази у всіх досліджуваних варіантах. По завершенню досліджень (10-й місяць деструкції) інтенсивність розкладання рослинних решток кукурудзи за дії біодеструкторів зросла до 66,3 % у варіанті із Триходерміном та до 64,2 % – Екостерну. Загалом, застосування Триходерміну та Екостерну сприяло збільшенню інтенсивності розкладання рослинних решток кукурудзи на 29,2 % та 27,1 % відносно контрольних показників деструкції. Найбільшу чисельність грибів роду Trichoderma на кожному етапі досліджень виявлено у варіанті із застосуванням Триходерміну, що дозволяє стверджувати про успішне адаптування та приживання біоагента препарату на рештках і в ґрунті. Проте збільшення загальної чисельність мікроміцетів спостерігалось у варіанті із обробкою Екостерном бактеріальним, що можна пояснити стимуляцією розвитку аборигенної мікрофлори ґрунту, зокрема грибів.

Оцінено вплив післяжнивного сидерату редьки олійної та різних способів його загортання на зміну потенційної засміченості чорнозему типового та фактичної забур’яненості кукурудзи. Виявлено, що застосування сидерату редьки олійної забезпечувало, порівняно з безсидеральним фоном, суттєве зменшення засміченості 0–30 см шару ґрунту насінням бур’янів на 2,9–7,1 млн шт./га, знижувало в посівах кукурудзи чисельність всіх біологічних груп бур’янів – на 0,2–4,5 шт./м2 та їх масу – на 4–68 г/м2, та підвищувало врожайність зерна культури на 1,5-1,8 т/га. З’ясовано, що заміна оранки безполицевими обробітками для загортання сидерату редьки олійної знижувала запаси насіння бур’янів в шарі ґрунту 0–30 см на 0,7–1,7 млн шт./га. При цьому встановлено суттєве зростання чисельності насіння бур’янів в шарі ґрунту 0–5 і 5–10 см – на 3,3–5,6 і 14,3–16,1 млн шт./га та суттєве їх зменшення в шарах 10–20 і 20–30 см – на 10,4–13,2 і 8,1–8,4 млн шт./га. Найглибший безполицевий обробіток забезпечував найменшу потенційну засміченість шару ґрунту 0–5 см – 24,4 і 22,3 млн шт./га, що порівняно з безполицевими розпушуваннями глибиною 13–15 і 6–8 см менше на 0,6–1,1 і 2,3–3,3 млн шт./га. Заміна оранки безполицевими обробітками збільшувала чисельність та масу бур’янів в посівах кукурудзи переважно за рахунок групи ярих ранніх та пізніх. Неістотну зміну даних груп бур’янів до оранки за кількістю (0,1–0,9 шт./м2) і масою (2–24 г/м2) спостерігали за безполицевого обробітку на глибину 25–27 см. За фактичною забур’яненістю до варіанту оранки найближчим був глибокий безполицевий обробіток на 25–27 см. Різниця між ними була несуттєвою на сидеральному фоні за загальною кількістю бур’янів – 0,6–10,9 шт./м2. Зменшення глибини безполицевого обробітку призводило до суттєвого збільшення в посівах кукурудзи кількості – на 5,0–9,1 шт./м2 та маси – на 98–207 г/м2 бур’янів, що обумовлювало істотний недобір врожаю в межах 0,5–0,8 т/га. Найвищу урожайність кукурудзи отримали при застосуванні післяжнивного зеленого добрива редьки олійної на сидерат та оранки (7,7 т/га) і безполицевого обробітку на глибину 25–27 см (7,9 т/га). Дієвіший контроль потенційної і фактичної забур’яненості за післяжнивного сидерату редьки олійної та проведенням безполицевого обробітку глибиною 25–27 см сприяв отриманню найвищої врожайності зерна кукурудзи – 7,9 т/га.
