Does Walking with a Load Affect Asymmetry in Bilateral Lower Extremity Mechanics?

PURPOSE This study sought to analyze the velocity and asymmetry between bilateral lower extremity mechanics according to the load during walking.METHODS A total of 14 adults with right leg dominance participated in this study (Male=7, Female=7). We respectively applied 30% of body weight load carriage on the subjects. Gait characteristics were analyzed with 3-dimensional cinematography and ground reaction force (GRF) system consisted of a center of gravity (COG) velocity, center of pressure (COP) area, leg stiffness, and GRF components.RESULTS Change in velocity of the maximum-minimum COG showed statistically significant in the main effect of load. The 1st anterior-posterior GRF (braking force) and vertical GRF were statistically significant in the main effects of load and bilateral lower limbs. The 2nd anterior-posterior GRF (propulsive force) was statistically significant in the main effect of load. COP area and leg stiffness exhibited statistically significant differences in the main effects of load and bilateral lower limbs. Interaction was observed in the vertical GRF, COP area. Furthermore , one-way variance analysis revealed load main effect had a greater influence on the increase in the magnitude of the vertical GRF and COP area than the asymmetry of bilateral lower limbs.CONCLUSIONS This study revealed the differences in asymmetry between the dominant and non-dominant lower limbs according to the load during walking. These findings may explain the differences shock attenuation and stress mechanisms between the bilateral lower limbs.

Longitudinal population dynamics of Mediterranean-Atlantic Arbutus during the last 30 ka

The current distribution of the genus Arbutus in the Old World prompts questions about its long-term population dynamics, location and extent of refuge areas, and modern vulnerability in relation to climate change and human activity. Our work aims to address these questions by combining modern occurrence data with a comprehensive survey of pollen and macrofossil records. Range maps of past distribution have been produced for the last 32 ka to investigate geographical trends in population dynamics and the timing of the appearance of Arbutus across different biogeographical regions. In the Atlantic domain, Arbutus has been consistently present during the last 32 ka, even during the Last Glacial Maximum. In the central and eastern Mediterranean regions, it progressively increased since the beginning of the Holocene, appearing along the coasts of the Black Sea and in the Levant during the Middle Holocene. In addition, the dynamics of Arbutus in a number of peripherals stands (Ireland, Canary Islands, Cyrenaica, Crimea, and Black Sea coasts) is discussed. The palaeobotanical evidence suggests that the delayed emergence of eastern populations and peripheral stands in the fossil record may be ascribed to a very low population density, rather than to a sequential migration process from the western sectors of the range. The comparison of fossil records and modern occurrences highlights an overall temporal continuity between long-term persistence areas and current centers of gravity and calls for density-weighted ecological models that may contribute to an informed assessment of conservation actions and strategies.

Smart Ground Support Equipment—The Design and Demonstration of Robotic Ground Support Equipment for Small Spacecraft Integration and Verification

In order to reduce the costs of integration and verification processes and to optimize the assembly, integration and verification (AIV) flow in the prototype development of small- and medium-sized spacecrafts, an industrial six-axis robot was used as a universal mechanical ground support equipment instead of a tailored prototype specific ground support equipment (GSE). In particular, a robotic platform offers the possibility of embedding verification steps such as mass property determination into the integration process while offering a wider range of ergonomic adaption due to the enhanced number of degrees of freedom compared to a classical static Mechanical GSE (MGSE). This reduces development costs for projects and enhances the flexibility and ergonomics of primarily mechanical AIV operations. In this paper, the robotic MGSE system is described, the operational prospects for in-line verification are elaborated and an example is given showing the possibilities and challenges of its operational use as well as its in-line mass determination capabilities. For this purpose, a method has been developed that allows for the precise measurement of the spacecraft mass using the robot’s existing technology without the need for additional hardware. Subsequent work will extend this to determine the center of gravity and the moments of inertia of the payload on the robotic MGSE.

Towards High-Precision Quadrotor Trajectory Following Capabilities: Modelling, Parameter Estimation, and LQR Control

Abstract Quadrotor unmanned aerial vehicles (UAVs) are small, agile four-rotor systems suitable for various applications, from surveillance to disaster support missions. Hence, achieving high-precision trajectory tracking is crucial for their successful deployment. This research focuses on modelling, parameter identification, and Linear Quadratic Regulator (LQR) control design for quadrotors, aiming to enhance their trajectory following capabilities. The quadrotor dynamics are a sixth degree-of-freedom (6DOF) equation of motion derived from Newton’s second law, encompassing moment of inertia, centre of gravity, weight, and thrust of propeller parameters. Experimental measurements are conducted to accurately determine these parameters, ensuring a realistic representation of the quadrotor system. Subsequently, a linearized model is constructed to provide a suitable plant for control system development. The LQR control design is intended to improve the trajectory tracking performance. This control strategy is validated through simulation and practical experiments, demonstrating its effectiveness in achieving high-precision trajectory following capabilites. The proposed approach demonstrates that LQR control effectively guides the quadrotor to resemble a predefined trajectory, experiencing only 3 % overshoot observed during the initial phase of flight.

Exploring the destination network in the context of tourism mobility: a multi-scale analytical framework

ABSTRACT Tourist mobility has attracted considerable attention from tourism academics and industry practitioners. This study explores the destination network, which is constructed based on tourists’ digital footprint data collected from online travel diaries, by proposing a multi-scale analytical framework. In particular, to analyze the tourism destination network comprehensively, the proposed framework integrates traditional quantitative analysis (gravity center model, statistics of flow directions) and three scales of network analysis (macroscopic, mesoscopic and microscopic network metrics), to reveal the structural patterns of the underlying pattern characteristics; furthermore, by using the multiple regression quadratic assignment procedure (MRQAP), the framework also explores the formation mechanism of the destination network by measuring the correlation and causality between the destination network and the corresponding transportation network, combining other potential driving factors. Based on illustrative case study data, which contains 18, 939 travel diaries and 51, 603, 044 transportation records from Chengdu-Chongqing economic circle in China, the empirical results show that the destination network is dynamically changed during four-year period, and the transportation network has great potential in explaining the formation of destination network. The dynamic characteristics of destination network and the exploration of formation mechanism offer the opportunities for improving destination planning and management.

Biomechanics as support for forensic expert reports in after pedestrian-car collisions

This paper systematically explores the mechanical properties of facial and cranial bones, aiming to contribute to the understanding of brain and cervical spine injuries from a mechanical/biomechanical perspective. The research also seeks to provide insights applicable in forensic practice, bridging the gap for engineering professionals not typi-cally involved in forensic medicine. Strength and stiffness parameters of facial and cra-nial bones were utilized to analyze forces leading to fractures, proposing a simple analyt-ical approach for determining head velocity upon striking a car windshield. Experimental testing was conducted to examine defects on the windshield resulting from an impactor's crash, simulating head impacts at varying velocities. Two approaches for determining head impact velocity during pedestrian-car collisions were explored. The first, neglect-ing body deformation effects, assumes that the manikin's center of gravity moves at the same speed as the impacting vehicle, resulting in an impact velocity that is approximate-ly twice the car's speed. The second, a more realistic scenario, considers slower move-ment of the body's center of gravity, yielding an impact velocity that is about one and a half times the car's speed, with a specific angle relative to the X-axis. Calculation reveals that head impact velocity decreases with reduced windshield inclination at constant ve-hicle speed. Experimental testing with an adult head impactor monitored impact velocity, acceleration, contact time, and puncture diameter and depth on the vehicle glass. Results align closely with published data, emphasizing higher injury risk near the location of fixation of the windshield to the frame of the vehicle. In forensic investigations, the re-search findings, including newly measured or calculated parameters, offer practical ap-plications. Acknowledging simulation limitations, the study emphasizes the reliance on experimental data for a more realistic understanding. Application of knowledge in expert opinions for car crashes with injuries involves considering windshield defect dimen-sions in relation to speed, minimizing the need for revision by expert opinions. This comprehensive exploration contributes to understanding biomechanical factors influenc-ing injuries, particularly in vehicular accidents, and underscores the importance of em-pirical data in forensic practice. The proposed analytical approach and experimental insights provide valuable tools for forensic professionals and contribute to the broader understanding of injury mechanisms.

CALCULATION OF THE LOGISTICS SYSTEM CENTER OF THE MAGNUM SUPERMARKET CHAIN IN PETROPAVLOVSK

The logistics system of Magnum supermarkets is the largest in Petropavlovsk, therefore the parameters of transport processes in this system have different directions and values, both in time and in space. Improving the efficiency of the transport logistics system is a priority. One of the factors influencing the efficiency of the transport logistics system is the location of warehouses and stores. In this article, the author calculated the center of the logistics system in order to determine the coordinates of the warehouse location in order to reduce transportation costs. For the calculation, the method of determining the center of gravity of the physical model of the distribution system was used. The results of the work are defined in the form of coordinate values. The calculation method can be used in distribution logistics. The data obtained cannot always be applied in practice, so this calculation method must be used together with other methods for determining the location of the warehouse, for example, the test point method.

Tele-connecting renewable energy availability from production to consumption via multi-national supply chains

Renewable energy transition is recognized as an irreplaceable strategy under low-carbon transition, which has gradually drawn due attention worldwide. Through combining the gravity center and the Lorentz curve, this study conducts a comparative assessment to depict gravity center trajectories across countries/regions and renewable energy inequality within income groups, providing a new perspective to clarify renewable energy transition worldwide. From the results, renewable energy availability experienced a rapid growth over time, and the gravity center of renewable energy availability shifted slightly towards the northeast. Through tele-connecting renewable energy availability via multi-national supply chains, renewable energy exchanges greatly expanded between 2000 and 2019, with Canada-USA, China-USA, Paraguay-Argentina, Mexico-USA, China-India, and China-Japan identified as intensive trade partners. In consideration of inequality levels, an obvious decrease in Gini coefficients could be witnessed, however, the Gini coefficients of renewable energy inequalities worldwide remained high. When compared, the upper-middle-income countries had the lowest Gini coefficients and gradually surpassed high-income countries as the most equitable group. By unveiling the trajectory and inequality of renewable energy availability from both production- and consumption-based perspectives, some rational and feasible strategies would be practical in consideration of economic growth and regional disparity to promote sustainable and equitable renewable energy transition worldwide.

Revealing early pest source points and spreading laws of Pantana phyllostachysae Chao in Moso bamboo (Phyllostachys pubescens) forests from Sentinel-2A/B images

Pantana phyllostachysae Chao is a leaf-eating pest that poses a significant threat to bamboo forest health. Current research mainly focuses on statically identifying damage using remote sensing images. However, the mechanism behind the damage's traceability remains unclear, making it difficult to pinpoint early infestation sources accurately. Additionally, our understanding of the pest's spreading laws is limited. This study leverages Sentinel-2A/B images from February to November 2021 to investigate P. phyllostachysae infestation traceability through the dynamic age algorithm and indicator analysis method. The results shed light on the distribution of early pest sources over the study period. By analyzing both the overall pest infestation “cluster” and its center of gravity, we dissect P. phyllostachysae infestation characteristics and paths monthly throughout the study period. Our findings reveal three zones with strong spreading momentum, three with slow spreading momentum, and two transitional zones during the February-November period, aligning with P. phyllostachysae occurrence patterns. However, the direction of P. phyllostachysae spreading varies, likely due to a combination of meteorological, topographical, vegetative biochemical, and human activity factors. This study introduces innovative approaches for identifying early pest source points and understand their spreading laws, contributing to more effective pest prevention and control in forest ecosystems.

A typology of polished stone axes in the middle Yellow River and their impact on early complex societies

Polished stone axes have long been recognized as essential tools directly related to logging and wood processing in sedentary societies, playing a crucial role in prehistoric people's survival and social production. Their evolution as production tools has been a driving force behind the advancement of society's productive capacities. In this article, information and data on stone axes from the middle Yellow River region are systematically compiled, presenting a typology based on 640 stone axes from 153 sites spanning the Middle Neolithic to the Bronze Age. The main conclusions derived from the study are as follows: (1) Typological study reveals that stone axes can be classified into 7 types. By examining the evolution of these types and their combinations, four distinct phases in the development of stone axes are identified, reaching its peak during the middle stage of Phase 4. (2) The flourishing of the stone axe types originated in the Yangshao period in the Guanzhong Plain. With the development of social complexity and the establishment of the Xia and Shang dynasties after the Longshan period, the center of gravity of stone axe types and assemblages gradually shifted to the Central Plains and the Fen River Valley. Finally, the genealogy spread to the eastern foothills of the Taihang Mountains and declined. (3) The types of stone axes from the late Yangshao period and the middle and late Longshan periods exhibit a clear shift, highlighting their functional differentiation during these periods. (4) The production of stone axes can be categorized into two modes based on the raw stone material used: (a) and (b). The metallization of tools, even during the so-called Bronze Age, experienced significant delays, and it was only during the Yinxu era that bronze axes began to replace some of the stone axes produced in mode (b). (5) The functional differentiation of axes and the transformation of the mode of production have played a role in inducing the emergence of social complexity and expediting its development to some extent.

Plantar load distribution with centers of gravity balance and rearfoot posture in daily lives of Taiwanese college elite table tennis players: a cross-sectional study.

Table tennis is an asymmetric sport involving the powerful forward swing of the upper limbs depends on the solid support of the lower limbs. The foot drive really affects the weight balance and stroke accuracy even though the distance and momentum of the lower limb displacement are limited within a limited range. Given that previous research on table tennis has typically focused on the footwork and stroke performance of professional players, the study aimed to investigate the daily static and dynamic plantar load distribution as well as the centers of gravity balance and rearfoot posture among Taiwanese college elite table tennis players. This is a cross-sectional study of 70 elite male table tennis players (age: 20.0 ± 0.9 years; height: 173.4 ± 5.1 cm, weight: 67.6 ± 5.3 kg, experience: 10.0 ± 1.6 years) and 77 amateur table tennis players of the same gender (age: 20.1 ± 0.8 years, height: 167.4 ± 4.4 cm, weight: 64.3 ± 4.0 kg, experience: 4.4 ± 1.2 years) from Taiwanese universities. The JC Mat optical plantar pressure analyzer was applied to determine the plantar load distribution along with arch index (AI) and centers of gravity balance. Assessment of rearfoot postural alignment was mainly used to contrast the performance of the centers of gravity balance. The static arch indices of both feet in the elite group were symmetrical and considered normal arches (AI: 0.22 ± 0.07) during their non-training and non-competition daily lives. Their static plantar loads were symmetrically concentrated on the bipedal lateral metatarsals (P < 0.05) as well as shifted to the medial and lateral heels (P < 0.05) and the lateral metatarsals (P < 0.05) during the walking midstance phase. Additionally, the plantar loads were mainly applied to the bipedal medial (P < 0.01) and lateral heels (P < 0.05) during the transitional changes between both states. Elite athletes had symmetrical and evenly distributed centers of gravity on both feet (left: 50.03 ± 4.47%; right: 49.97 ± 4.47%) when standing statically, along with symmetrical rearfoot angles and neutral position of the subtalar joint (left: 2.73 ± 2.30°; right: 2.70 ± 2.32°) even though they were statistically lower than those of the amateur athletes (P < 0.05). The daily static and dynamic foot patterns of Taiwanese college elite table tennis players were characterized by plantar load distribution on the lateral metatarsals and the entire calcaneus along with balanced centers of gravity and normal rearfoot posture. This foot and posture layout outlines the excellent athletic performance of the foot and ankle in professional athletes. Portions of this text were previously published as part of a preprint (https://doi.org/10.21203/rs.3.rs-2993403/v1).

A new propulsion system GUI based control amenable model development for high‐power rockets

SummaryThis paper proposes a new algorithm to model and characterize an autonomous high‐power rocket using an indigenously developed graphical user interface (GUI) platform. This platform features a newly devised app, termed as THIEC Rocketry App which embeds the simulation based analysis to determine the design parameters of the rocket, required for a vertical flight. A solid propellant using potassium nitrate and sucrose, also known as rocket‐candy, is considered for the GUI development. The GUI facilitates the designer to specify the desired flight parameters for the rocket propulsion system. Various characteristic plots for visualization and analysis are made available in GUI. The obtained parameters from the GUI are then utilized in computer‐aided designing (CAD) for further identification of geometrical parameters like inertia tensor, center of gravity (CG) and center of pressure (CP). The mathematical control amenable model of the rocket is then developed using first principles so as to achieve an altitude up to 3 km. The overall system represents a complex nonlinear multi‐input multi‐output (MIMO) dynamics, having six degrees of freedom. The Newton‐Euler formulation is employed to develop the equations of motion. The attitude control using canards is analyzed via simulations for the complete flight path ‐ the boost and coast flights. Finally, the developed GUI based model is validated by practically manufacturing the components of the propulsion system for the small‐scale high‐power rocket. The proposed model will create the pathway for the development of some robust model‐based control schemes for such autonomous rockets in future.

Evaluation of the movement performance of a vibrating screen due to machining errors on the shaft

This paper presents a case study investigating the impact of a machining error in the shaft of a medium-sized Vibrating Screen on its operation and vibration parameters. In vibratory equipment, the operational principle relies on a mechanism comprising a shaft with eccentric masses at each end. Depending on the machine's purpose, one to three drive shafts may be present. Precision manufacturing is crucial to ensure minimal positional difference in the center of gravity between the eccentric masses at both ends of the shaft. Even a slight error in manufacturing these eccentric masses or premature wear in the key and shaft can result in distortions in the vibratory movement of the machine, leading to potential structural failures such as cracks and component fractures. Apart from structural issues, such defects can result in performance loss, causing substantial losses for large-scale equipment. This study delves into a detailed analysis of a machining error in a drive shaft that resulted in distortions in the vibratory motion of a Vibrating Dewatering Screen, model AI PVD 4818 1A, with a nominal length of 4.8 m, internal width of 1.8 m, and a total weight of 66267 N. The manufacturing error in the shaft resulted in such significant distortions in the screen’s working motion that it completely hindered acceptable equipment performance, necessitating the replacement of the faulty part.

Research on Calibration Method of Six Dimensional Force Sensor at the End of Robot

A six-axis force sensor calibration method for industrial robots is proposed to meet the demand for precise force measurement of end effectors in industrial robots. Firstly, establish a sensor data relationship calculation model, and based on this, focus on considering the interference caused by sensor "zero drift"; Then, the least squares method is used to determine the inclination angle between the robot's end effector and the installation of the six-axis force sensor, the gravity of the end effector, and the coordinate parameters of the center of gravity. Finally, a CR5 robotic arm experimental platform was built to verify the feasibility of the algorithm. The experiment showed that the calibrated sensor maintained a stable force value of 0N without external force, verifying the accuracy of the calibration algorithm.

Effect of thoracolumbosacral braces on running ground reaction force components in male individuals with kyphosis

Background & aimsBraces are one of the methods for kyphosis treatment, but they can relocate the center of gravity of the trunk, affecting the ground reaction force (GRF) during running. Therefore, this study aimed to investigate the effects of two types of thoracolumbosacral braces on running GRF components in individuals with kyphosis. Materials & methodsParticipants were 15 males diagnosed with kyphosis who volunteered in this quasi-experimental study. Each subject performed the barefoot running trials on the force plate with one simple brace, with a sensor brace, and without the brace condition. The ground reaction forces components were calculated in the stance phase. Statistical analysis was done with repeated measures test with a significant level of 0.05. ResultsPeak medial ground reaction force when running with a sensor brace was lower than running with a simple brace (p = 0.017). Free moments were similar during three running conditions (p > 0.05). ConclusionLower maximum medial ground reaction force while using a sensor brace may possibly demonstrate the beneficial effects of a sensor brace in individuals with kyphosis.

Numerical Computation of Restoring Time and Prediction of Self-Righting Process

Excellent self-righting performance is important to guarantee the normal navigation of Unmanned Surface Vehicles (USVs) after overturning, and the restoring time is an important index in design requirements. Traditionally, the static stability method and experiments on full-scale vehicles were used to analyze the large-angle stability of the USV. However, when it comes to the analysis of self-righting performance, the traditional static stability method will cause improper integration, and experiments are not convenient. To solve these problems, an improved static stability method was proposed, and a whole self-righting process simulation of a physical model was finished. The numerical simulation method was used to predict the self-righting process of a USV under four working conditions. Firstly, a midpoint average method based on the static stability theory was adopted to compute the static restoring time, and the results were compared with the results of the references, which verifies the effectiveness of the midpoint average method. Also, the midpoint average method is convenient because it only needs the restoring arm curve, the width and the gravity center height. Then, a numerical simulation of a physical model in static water was finished, and an experiment for a physical model in a towing tank was conducted. Comparing the restoring time of the midpoint average method, the numerical simulation and the experiment, the results show that the numerical simulation has high accuracy. Moreover, the numerical simulation was used to predict the self-righting process and analyze the self-righting performance of a USV under four working conditions.

Dynamic evaluation of China's atmospheric environmental pressure from 2008 to 2017: Trends and drivers

Evaluating the pressure of atmospheric pollutant emissions on the atmospheric environment is crucial for effective pollution control and emission reduction policies. This study introduces a novel Atmospheric Environmental Pressure Index (AEPI) and employs a dynamic comprehensive method to evaluate China's Atmospheric Environmental Pressure (AEP) across 31 provinces from 2008 to 2017. The drivers of AEP were analyzed using a spatial panel data model, uncovering the integral role of pollution reduction policies, particularly the Air Pollution Prevention and Control Action Plan, which led to a 25 % reduction in AEP during its enforcement. Our findings reveal significant spatial disparities in AEP, with higher levels in the Beijing-Tianjin-Hebei and Yangtze River Delta regions. The regression analysis identifies economic development, industrial structure, energy efficiency, environmental regulations, and urbanization as key influencing factors, though their impacts vary across different regions, suggesting the need for region-specific pollution control policies. Furthermore, the shift in the AEP gravity center from 2008 to 2017 indicated a southeastward movement, suggesting the necessity to focus air pollution control efforts on the southeast provinces. In conclusion, the AEPI developed in this study enables comparative analysis of AEP across different regions and facilitates the monitoring of long-term trends, which is valuable in guiding regional air pollution control in China.

Anti-Swaying Control Strategy of Ship-Mounted 3-RCU Parallel Platform Based on Dynamic Gravity Compensation

It is essential to ensure stability during marine transportation or the installation of high center of gravity loads. The heavy loads increase gravity disturbance, affecting the steady-state-error control of the multiple degrees of freedom (DOFs) motion compensation platform. In this paper, we propose a proportional derivative (PD) controller with dynamic gravity compensation (PDGC) for a 3-RCU (revolute–cylindrical–universal) parallel platform to improve the control effect of marine motion compensation for high center of gravity loads. We introduce an evaluation parameter of load stability and a weighting coefficient of anti-swaying control to tune the controller performance. The controller can set its control target between the two, keeping the load contact surface level and allowing the load center of gravity with the least movement. By deriving the Jacobian matrix, the gravity disturbance in the joint space is calculated and is compensated in the controller. First, we verify the control superiority of this controller over the PD controller under sinusoidal excitation in simulation and validate the effectiveness of the proposed anti-swing strategy. Then, the experiments are conducted with random excitation. The root mean square (RMS) value of the load’s residual angle with the proposed controller is reduced to 32.2% and 17.6% in two directions, respectively, compared with the PD controller under class 4 sea state excitation. The proposed method is effective for the anti-swaying control of ship-mounted 3-RCU parallel platforms.
